Female part 32 is in this embodiment, also shown in Fig. 6 (a), to be made up of four aggregates of cutting apart female part 320 at processing drum axis direction and the circumferential mode that respectively is divided into two groups.But female part also can be made up of the monomer that has with the same structure of a plurality of aggregates of cutting apart female part, also can be made up of the aggregate of cutting apart female part of varying number.
Cut apart female part 320 and be made as same structure respectively, have framework 321 and sieve nest 322.Cut apart female part 320 at processing drum axis direction and circumferentially respectively be set up in parallel two, adjacent cut apart female part 320 and framework 321 each other with contact at suitable end face the circular-arc mode of formation with respect to the wall portion of formation process chamber 33 via installations such as connecting pieces.
Like Fig. 7, shown in Figure 8, framework forms sheet 321F, 321B, left and right sides framework formation sheet 321L, 321R before and after on framework 321, possessing.Before and after framework form sheet 321F, 321B and be respectively along the outer peripheral face of body portion 311, the plate-shaped member of the partial arc shape of convex curvature downwards, keep the setting of predetermined distance ground at fore-and-aft direction.
Left and right sides framework forms sheet 321L, 321R is respectively along the plate-shaped member of the linearity of fore-and-aft direction extension, and framework forms between the mutual left and right end portions of sheet 321F, 321B before and after being set up in.Like this, framework 321 is formed by the front and back framework that sheet 321F, 321B and left and right sides framework form sheet 321L, 321R constitutes the frame shape.
Possess a plurality of sieve nests at sieve nest 322 and form sheet 322A.Sieve nest forms sheet 322A and forms along the bar-like member of the linearity of fore-and-aft direction extension, and in this embodiment, forming special in bar-like member is the cylinder-like part of curved surface with the outer peripheral face.A plurality of sieve nests form sheet 322A and dispose abreast with left and right sides framework formation sheet 321L, 321R respectively, and framework forms between sheet 321F, 321B before and after being set up in along the every separated predetermined distance of its bending direction.
At this, sieve nest forms as shown in Figure 9 being set to of sheet 322A, and its internal diameter is certain in the fore-and-aft direction scope, and the end 322Aa before and after external diameter is limited to is a path, and near the mode that is regarded as convex with section the end of front and back constitutes.On the other hand, the framework of front and back form sheet 321F, 321B along bending direction every possess at a distance from predetermined distance have end 322Aa almost a plurality of through hole 321Fa, the 321Ba of same diameter that forms the front and back of sheet 322A with sieve nest.
And the end 322Aa that sieve nest forms the front and back of sheet 322A embeds respectively with the front and back framework and forms sheet 321F, through hole 321Fa, 321Ba that 321B is corresponding.Thus, sieve nest form sheet 322A be arranged at before and after framework form the scope between sheet 321F, the 321B, by the front and back framework forms sheet 321F, 321B prevents deviating from, and rotate around the axis that this sieve nest forms sheet 322A and to be supported freely.Below, describe as the outer peripheral face that sieve nest forms sheet 322A with end 322Aa and outer peripheral faces processing drum 31 opposed parts that remove sieve nest formation sheet 322A.
Form in the supporting structure of sheet 322A at this sieve nest; It is as shown in Figure 9 that sieve nest forms sheet 322A; Comparing suitably increase with the external diameter of end, front and back 322Aa with the external diameter of these processing drum 31 opposed parts sets; As shown in Figure 5, to dispose from the distance of the outer peripheral face of processing drum outer peripheral face to processing drum 31 equidistant mode with the outer peripheral face of processing drum side end face to the processing drum 31 of the past after-frame bodily form 321F in blocks, 321B.That is, sieve nest forms sheet 322A and is positioned at its processing drum side outer peripheral face and forms the mode that the processing drum side end face of sheet 321F, 321B is almost with one side with the front and back framework and dispose.
In addition; Sieve nest forms sheet 322A and compares with the external diameter of the end 322Aa of front and back suitably to increase with the external diameter of these processing drum 31 opposed parts and set, and the short mode of distance of outer peripheral face that forms processing drum side end face to the processing drum 31 of sheet 321F, 321B with the distance from processing drum side outer peripheral face to the outer peripheral face of processing drum 31 than the framework from front and back disposes.That is, sieve nest formation sheet 322A more disposes near the mode of processing drum 31 than the processing drum side end face that front and back framework forms sheet 321F, 321B with processing drum side outer peripheral face.
In other words; Sieve nest forms sheet 322A and compares suitably increase setting with the external diameter of the end 322Aa of front and back with the external diameter of these threshing tube 31 opposed parts; As shown in Figure 5; With processing drum side outer peripheral face from processing drum side end face that the framework of front and back forms sheet 321F, 321B hardly to the side-prominent mode of processing drum 31, or more dispose to processing drum 31 side-prominent modes with the processing drum side end face that the framework than front and back forms sheet 321F, 321B.
In addition; Sieve nest forms sheet 322A supporting structure shown in Figure 10 (a); Also can be following formation: set external diameter and framework that sieve nest forms sheet 322A roughly the samely and form the through hole 321Fb that sheet 321F, 321B possess, the external diameter of 321Bb in front and back; So that sieve nest forms the state that the end 322Ac of the front and back of sheet 322A runs through through hole 321Fb, 321Bb; Form sheet 321F, 321B from the framework of the front and back of each end 322Ac the external diameter of outstanding part is bigger than the external diameter of through hole 321Fb, 321Bb laterally through making; Prevent that sieve nest from forming sheet 322A the past after-frame bodily form 321F in blocks, 321B deviates from, and support freely around the axis rotation of this sieve nest formation sheet 322A.
Perhaps; Sieve nest forms the supporting structure of sheet 322A shown in Figure 10 (b); Framework inboard through framework formation sheet 321F, 321B in front and back sets firmly the supporting mass 325 of a plurality of ring-types; The end 322Aa that makes each sieve nest form sheet 322A embeds in this supporting mass 325, also can support sieve nest freely and form sheet 322A with respect to front and back framework formation sheet 321F, 321B rotation thus.
Under the situation of this supporting structure, framework forms that sheet 321F, 321B are last to form a plurality of through hole 321Fb, 321Bb to have the little diameter of internal diameter that forms sheet 322A than sieve nest in front and back, and is that concentric mode is configured with the opening with each supporting mass 325.And, more lean on framework inboard than supporting mass 325, near the end 322Aa of sieve nest formation sheet 322A, be formed with through hole 322Ad.
Like this, form the state of the internal communication of sheet 322A, be communicated with the inside and outside of supporting mass 325, and be communicated with sieve nest by through hole 322Ad and form the inside and outside of sheet 322A by through hole 321Fa, 321Ba with the inside of supporting mass 325 and sieve nest.
Thus; In the tip-clearance of supporting mass 325 and framework formation sheet, piled up under the situation of dust; Through utilize air gun etc. in the past the through hole 321Fa, 321Ba of after-frame bodily form 321F in blocks, 321B towards the delivered inside air of supporting mass 325; Can remove this dust simply, realize preventing that the rotation that is formed sheet 322A by the sieve nest that dust causes from stopping.
In addition; Form in the supporting structure of sheet 322A at above-mentioned sieve nest; A plurality of sieve nests form sheet 322A and see in the front of processing drum 31; As shown in Figure 5; Form sheet 322A and form the interval that sheet 322A adjacent sieve nest of bending direction that framework forms sheet 321F, 321B in front and back forms sheet 322A with certain sieve nest, handle the leading section of tooth 313 and handle tooth 313 at the interval of the leading section of the adjacent processing tooth 313 of fore-and-aft direction, circumferentially arrange for the mode of same degree in processing drum with respect to this with certain of processing drum 31 with respect to this sieve nest.
Therefore; Certain sieve nest forms sheet 322A and together is disposed at the first straight line L1 that extends to the processing drum radial outside from the pivot of processing drum 31 when going up with handling tooth 313, forms the adjacent sieve nest of bending direction that the framework of sheet 322A in front and back form sheet 321F, 321B with respect to certain sieve nest and forms sheet 322A and also be disposed at from the pivot of processing drum 31 at the adjacent processing tooth 313 of fore-and-aft direction and circumferentially stagger predetermined angular on the second straight line L2 that the processing drum radial outside extends and form with respect to the first straight line L1 in processing drum with handle tooth 313 with respect to certain.
Promptly; Certain sieve nest forms sheet 322A when handling the opposed mode of tooth 313 leading sections and dispose with certain of processing drum 31, with respect to certain sieve nest form the adjacent sieve nest of bending direction that the framework of sheet 322A in front and back form sheet 321F, 321B form sheet 322A also with handle tooth 313 with respect to certain and dispose and form in the opposed mode of leading section of the adjacent processing tooth 313 of fore-and-aft direction.In other words, each other adjacent sieve nest form sheet 322A with the adjacent leading section of respectively handling tooth 313 of the fore-and-aft direction of processing drum 31 simultaneously opposed mode dispose and form.
At this moment; See in the front of processing drum 31 processing drum 31 respectively handle tooth 313 and with respect to this processing tooth 313 at the circumferential interval of the processing drum of the adjacent processing tooth 313 of fore-and-aft direction because of set as previously mentioned roughly the samely; Therefore, each sieve nest forms sheet 322A and forms the circumferential interval of processing drum that sheet 322A adjacent sieve nest of bending direction that framework forms sheet 321F, 321B in front and back forms sheet 322A with respect to this sieve nest and sets also roughly the samely.Therefore, the bending direction of a plurality of sieve nests formation sheet 322A framework formation sheet 321F, 321B in front and back is equally spaced arranged.
In addition; In this embodiment, a plurality of sieve nests are formed sheet and form sheet interval each other with identical at the leading section interval each other of handling tooth with sieve nest; And handling tooth rim to arranging for equally spaced mode, still, corresponding to the change at the leading section interval each other of handling tooth; Sieve nest forms sheet interval each other also can be big to form sheet interval each other at a part of sieve nest, forms little mode unequal interval ground, sheet interval each other at remaining sieve nest and arrange.
In addition, shown in Figure 11 (a), lining body 323F, the 323B of front and back also can be set respectively in the framework formation sheet 321F of the front and back of supporting sieve nest formation sheet 322A, the framework outside of 321B.Lining body 323F, 323B are made as identical structure respectively, have fixed part 323Fa, 323Ba and the 323Fb of lining portion, 323Bb, shown in Figure 11 (b), form and analyse and observe L word shape.
Fixed part 323Fa, 323Ba form with the front and back framework and form sheet 321F, the roughly the same shape of 321B.And fixed part 323Fa, 323Ba dispose with the mode that forms sheet 321F, 321B from the framework outside and front and back framework and overlaps, and be relative with it, releasably fixes via connecting piece at the every separated predetermined distance of bending direction.
The 323Fb of lining portion, 323Bb has and the front and back framework forms sheet 321F, 321B the width of bending direction extend along fore-and-aft direction towards the framework inboard from the upper end of fixed part 323Fa, 323Ba with the width ground formation of degree.At this moment the 323Fb of lining portion, the front and back width setup of 323Bb form the degree of the supporting part of sheet 322A for the sieve nest of framework formation sheet 321F, 321B before and after can covering.
Like this, the threshing portion 30 of combine 1, female part 32 also can be following formation: framework forms sheet 321F, last swivel bearing front and back lining body 323F, the 323B partly that covers each sieve nest formation sheet 322A of sieve nest 322 from processing drum 31 sides that be provided with respectively of 321B in the front and back of framework 321.
Thus, when threshing operations, be difficult to make the stem etc. of straw to be wrapped in the swivel bearing part that each sieve nest of sieve nest 322 on the female part 32 forms sheet 322A, and soil etc. also is difficult to invade.Therefore, can suppress the reduction of durability that sieve nest forms the swivel bearing portion of sheet 322A, and can prevent that the rotation that sieve nest forms sheet 322A from stopping.
In addition, shown in figure 12, on sieve nest 322, can at least one sieve nest among a plurality of sieve nests formation sheet 322A be formed sheet 322A and be made for the shape that has protuberance 322Ae at its outer peripheral face.This protuberance 322Ae is along spiralization, and this spiral is consistent with sieve nest formation sheet 322A axis, and this protuberance 322Ae is configured on fore-and-aft direction between the rear and front end portion of sieve nest formation sheet 322A.
Like this; The threshing portion 30 of combine 1, female part 32 also can be following formation: at least one sieve nest forms on sheet 322A and has spiral helicine protuberance 322Ae in a plurality of sieve nests formation sheet 322A of sieve nest 322, and this protuberance 322Ae is consistent with this sieve nest formation sheet 322A axis.
Thus, the sieve nest with spiral helicine protuberance 322Ae forms sheet 322A when threshing operations, utilizes the straw of being carried by processing drum 31, does not have the sieve nest of protuberance 322Ae to form sheet 322A than other and rotates more.And the sieve nest with spiral helicine protuberance 322Ae forms sheet 322A and forms under the situation more than two, with the rotary speed rotation that has nothing in common with each other.
Therefore, the flow velocity of the straw that can quicken to be transferred also prevents its stagnation, and can realize the reduction of power to processing drum 21.In addition, can promote grain, suppress to produce dirty grain from the leaking down of female part 32.In addition, can change the angle of straw with respect to the moving direction of handling tooth 313, it is residual to reduce processing.
In addition, in the process chamber 33 that this processing drum 31 and female part 32 are set, be provided with a plurality of blades 35 and a plurality of dirt valves 36 that send.A plurality of blades 35 are arranged at the left side side on the top of the body portion 311 that constitutes processing drum 31,, in the scope relative with the front and back central portion, are set up in parallel at the processing drum axis direction from the leading section of body portion 311 with keeping predetermined distance.Dispose these a plurality of blades 35 fore-and-aft direction scope specifically, near the processing tooth 313 that is disposed at the front position from outer peripheral face in body portion 311 near the rearward end of first chaffer 411 of the oscillatory sorting device 41 of sorting portion 40.
Each blade 35 is seen in the front of processing drum 31; Extending out towards body portion 311 with the mode of handling tooth 313 repetitions; Be disposed at the rotation that utilizes processing drum 31 and handle between the path of tooth 313 rotation; When carrying out the threshing of processing drum 31 and female part 32 generations, can cut off straw and make it to shorten.Like this, be implemented in the raising to the threshing performance of straw of threshing portion 30, be implemented in the raising of separation performance of first chaffer 411 of 40 pairs of threshing objects of sorting portion.
On the other hand; A plurality of dirt valves 36 that send are provided with the mode that above the body portion 311 of processing drum 31, extends out along left and right directions;, in the scope relative, be set up in parallel from the leading section of body portion 311 at the processing drum axis direction with the rear portion with keeping predetermined distance.The top board face that respectively send dirt valve 36 to be rotatably supported in process chamber 33, variable direction with respect to this processing drum axis direction, and at one end portion and bar-like member 37 link, and send dirt valve 36 rotatable linkedly with other.
And the action bars 38 that is arranged at the outside of process chamber 33 is connected with a plurality of dirt valves 36 that send that are disposed at the front position in the dirt valve 36 that send, and utilizes the operation of this action bars 38, and a plurality of dirt valves 36 that send together change its direction.The direction of sending dirt valve 36 utilizes near the guide post 39 that is arranged at it to be fixed in the operating position of hope through action bars 38, keeps suitable direction thus.Like this, can regulate its holdup time according to the condition of straw, be implemented in the raising to the threshing performance of straw of threshing portion 30 at process chamber 33.
As stated, the threshing portion 30 of combine 1 possesses axis processing drum 31 that rotatably sets and the female part 32 that is disposed at the below of processing drum 31 around fore-and-aft direction.Processing drum 31 possess the body portion 311 of the drum that extends along fore-and-aft direction and from the outer peripheral face of body portion 311 to the outstanding a plurality of processing teeth 313 of processing drum radial outside; Tooth 313 be will handle and axis and these processing drum 31 consistent and coiling direction unanimities will be configured to; Be positioned at the first different spiral 301 of spirals and the intersection point of second spiral 302; And the front in processing drum 31 is seen; Mode configuration process tooth 313 that a mutual part repeats only to be arranged and sets first spiral 301 roughly one all front or rear of spirals with respect to these processings tooth 313 to the second spirals 302 littlely at the adjacent processing tooth 313 of fore-and-aft direction; Constituting of female part 32; Possess: framework 321, its have along the outer peripheral face of the body portion 311 of processing drum 31 downwards the framework of the front and back of the convex curvature framework that forms sheet 321F, 321B and be set up in these front and back form sheet 321F, 321B about each end between about framework formation sheet 321R, 321L; Sieve nest 322, it has along the processing drum axis direction is that a plurality of sieve nests of the tubular that extends of fore-and-aft direction form sheet 322A, the framework in front and back forms between sheet 321F, the 321B and sets up a plurality of sieve nests formation sheet 322A along bending direction is every at a distance from predetermined distance ground.
Thus, when threshing operations, one second spiral 302 is configured to the tooth 313 respectively handled of row at fore-and-aft direction to act on the threshing object that is transferred is on the straw in the past with being separated with the time difference in order in processing drum 31 upper edges.Therefore, can suppress straw and be wound in rope form.In addition, the sieve nest of sieve nest 322 forms sheet 322A and forms cylindricly on female part 32, becomes entangled in sieve nest and forms on the sheet 322A so can suppress straw.Therefore, threshing operations smoothly can be carried out, the raising of threshing performance can be realized.And, handle tooth 313 and act on the straw as previously mentioned, so can alleviate biography to the overload of the moment of processing drum 31, noise and the generation vibration that processing drum 31 produces.Therefore, can cosily improve the sensation of taking of the combine 1 that possesses this threshing portion 30.
Threshing portion 30, the female part 32 of combine 1 are processed following formation: the framework in the front and back of framework 321 forms each sieve nest that the last axis rotation that forms sheet 322A around this sieve nest of sheet 321F, 321B supports sieve nest 322 freely and forms sheet 322A.
Thus, when threshing operations, the sieve nest of sieve nest 322 formation sheet 322A contacts with straw and rotates on female part 32.Therefore, even straw for example contains the straw of washy soybean, also be difficult to be wrapped on the sieve nest 322, be difficult to thrust in the sieve nest 322, promote that grain leaks down from female part 32, can reduce the dirty grain of loss, generation of grain, and can stop the straw delay in flow.Therefore, threshing operations smoothly can be carried out, the raising of threshing performance can be realized.
Threshing portion 30, the female part 32 of combine 1 are processed following formation: will see in the front of processing drum 31; To be set at adjacent sieve nest formation sheet 322A interval each other at the bending direction of sieve nest 322, these adjacent each other sieve nests form sheet 322A with simultaneously opposed at the adjacent leading section of respectively handling tooth 313 of the fore-and-aft direction of processing drum 31.
Thus; When threshing operations; Certain sieve nest of sieve nest 322 forms sheet 322A and handles tooth 313 when opposed on female part 32; It is also opposed with processing tooth 313 to form sheet 322A at the adjacent sieve nest of fore-and-aft direction, and these adjacent each other sieve nests form sheet 322A and always handle the rotation of tooth 313 clamping straw ground with each.Therefore, straw flows with certain speed roughly, can quicken the flowing of straw between processing drum 31 and the female part 32.Therefore, threshing operations smoothly can be carried out, the raising of threshing performance can be realized.
Threshing portion 30, the processing drum 31 of combine 1 are processed following formation: the processing tooth 313 that in a plurality of processing teeth 313, comprises the rear that is positioned at female part 32; Be provided with and handled tooth 313, so that wherein a part repeats for female part 32 in the positive read fortune of this processing drum 31.
Thus, when threshing operations,, handle tooth 313 at the rear of female part 32 and also cut off the straw that has twined even under the situation of having twined straw.Therefore, promote the discharge of straw, can quicken the flowing of straw between processing drum 31 and the female part 32.In addition, can realize passing reduction to the power of processing drum 31.Therefore, can carry out threshing operations swimmingly, can realize the raising of threshing performance.
Threshing portion 30, the female part 32 of combine 1 are processed following formation: the processing drum side outer peripheral face that the sieve nest of sieve nest 322 is formed sheet 322A forms processing drum side end face that front and back framework with framework 321 forms sheet 321F, 321B for roughly with simultaneously.
Thus, on female part 32, do not exist the sieve nest of sieve nest 322 to form the front and back framework formation sheet 321F of sheet 322A and framework 321, the step of 321B, so when threshing operations, straw flows on female part 32 swimmingly.Therefore, straw can be suppressed to the entanglement of the sieve nest 322 of female part 32 and thrust etc., the obstruction that produces in threshing portion 30 can be alleviated.In addition, also can alleviate the vibration that produces in threshing portion 30.
The grain portion of portion 30 of combine 1, female part 32 are processed following formation: form each sieve nest formation sheet 322A of sieve nest 322 cylindric.
Thus, during threshing operations, straw is difficult to be wrapped on the sieve nest 322 of female part 32.Therefore, can alleviate the obstruction that produces in threshing portion 30.In addition, can realize being difficult to forming sheet 322A damage grain, can realize the reduction of damaged kernel by sieve nest.And, be prone to make sieve nest to form sheet 322A rotation, can promote grain to leak down from female part 32, can suppress the generation of dirty grain.
And threshing portion 30, the female part 32 of combine 1 are also processed following formation: framework forms sheet 321F, last swivel bearing front and back lining body 323F, the 323B partly that covers each sieve nest formation sheet 322A of sieve nest 322 from processing drum 31 sides that be provided with respectively of 321B in the front and back of framework 321.
Thus, when threshing operations, the stem of straw is difficult on female part 32 swivel bearing that each sieve nest to sieve nest 322 forms sheet 322A and partly tangles, and soil etc. is difficult to invade.Therefore, can suppress the reduction of durability that sieve nest forms the swivel bearing portion of sheet 322A, can prevent that the rotation that sieve nest forms sheet 322A from stopping simultaneously.
In addition; Threshing portion 30, the female part 32 of combine 1 are also processed following formation: at least one sieve nest forms on sheet 322A and has spiral helicine protuberance 322Ae in a plurality of sieve nests formation sheet 322A of sieve nest 322, and this protuberance 322Ae is consistent with this sieve nest formation sheet 322A axis.
Thus, the sieve nest with spiral helicine protuberance 322Ae forms sheet 322A when threshing operations, utilizes the straw of being carried by processing drum 31, does not have the sieve nest of protuberance 322Ae to form sheet 322A with other and compares rotation more.And, form sheet 322A at sieve nest and form under the situation more than two, with different separately rotary speed rotations with helical form protuberance 322Ae.
Therefore, the straw that can quicken to be transferred mobile prevent it and stagnate, and can realize being delivered to the reduction of the power of processing drum 31.In addition, promote that grain leaks down from female part 32, can suppress the generation of dirty grain.In addition, can change the angle of straw with respect to the moving direction of handling tooth 313, it is residual to reduce processing.
In addition, threshing portion 30 particularly its processing drum 31 also can constitute as follows, is explained.
Like Figure 13, Figure 14, shown in Figure 15, it constitutes processing drum 31, has body portion 311; The impeller 312, the spiral that are installed on body portion 311 are handled tooth 314; Be installed on the independent process tooth 315 of spiral processing tooth 314 etc.Body portion 311 have with process chamber 33 with the front and back length of degree and form cylindricly, extend along the processing drum axis direction.But only the leading section of body portion 311 forms the cylindric of the chamfering different with other part.
Body portion 311 is with the straw input port 331 of its leading section in the face of process chamber 33, and rearward end disposes in the face of the mode of the straw outlet of process chamber 33.And body portion 311 by the fulcrum that is set up in the processing drum axis direction 34 supportings, under the situation that this fulcrum 34 is driven in rotation at the power that obtains engine, can be pivot and one rotation with it with fulcrum 34 in process chamber 33.
Impeller 312 forms helical form, is arranged at the outer peripheral face of the leading section of body portion 311.On the other hand, spiral is handled tooth 314 so that the leading section than body portion 311 more leans on the outer peripheral face of rear portion side to be provided with to the outstanding mode of processing drum radial outside at the rear of impeller 312.Below, describe with the outer peripheral face that more leans on rear section than the leading section of body portion 311 outer peripheral face as body portion 311.
A plurality of independent process teeth 315 are provided with to the outstanding mode of processing drum radial outside to handle at spiral in the tooth 314 in more detail in the front that spiral is handled the outer peripheral edges portion of tooth 314.In the processing drum 31 of this formation, a plurality of independent process teeth 315 form and are equivalent to above-mentioned processing tooth 313, and on this basis, spiral is handled tooth 314 and is arranged between the outer peripheral face of these independent process teeth 315 and body portion 311.
The installation site that spiral is handled tooth 314 and each independent process tooth 315 is that first spiral 301 and second spiral 302 determine according to the spiral with two kinds of the solid line of Figure 13 and double dot dash line outer peripheral face that represent, that be set in body portion 311.First spiral 301 and second spiral 302 are spirals as separately coiling direction of following content setting, in the length of the processing drum axis direction about a week on the outer peripheral face of body portion 311.
That is, first spiral 301 is set to second spiral 302 all has the axis that the edge fore-and-aft direction consistent with the axis of processing drum 31 extends, and mutual coiling direction is identical, and spirals is different each other.First spiral 301 is set with its spirals mode littler than the spirals of second spiral 302, around the outer peripheral face of body portion 311 enclose the land more around.
Second spiral 302 is bigger than the spirals of first spiral 301 with its spirals, and sets with respect to the very large mode of front and back length of body portion 311, not around the outer peripheral face of body portion 311, reaches the rearward end of body portion 311.And second spiral 302 possesses many, in this embodiment, possesses eight, and second spiral 302 keeps certain compartment of terrain almost parallel and non-intersect each other, only intersects with first spiral 301.
Like this, spiral is handled tooth 314 first spiral, 301 configurations on the outer peripheral face edge of body portion 311.A plurality of independent process teeth 315 are handled the outer peripheral edges portion of tooth 314 along the 301 every separated equal intervals ground configurations of first spiral at spiral, and along the 302 every separated equal intervals ground configurations of second spiral.That is, independent process tooth 315 disposes with the mode of the intersection point that is positioned at first spiral 301 and second spiral 302.At this moment, the quantity that is disposed at the independent process tooth 315 about week of first spiral 301 is the quantity of second spiral 302.
Consequently, in a plurality of independent process teeth 315 certain week of first spiral 301 by the independent process tooth 315 of the independent process tooth 315 of regulation order configuration and the preceding of first spiral 301 or the same order configuration that next is all on the second identical spiral 302 to arrange in the adjacent mode of the fore-and-aft direction that becomes the processing drum axis direction.Simultaneously, like Figure 15, shown in Figure 16, these see in the front of processing drum 31 that at the adjacent independent process tooth 315 of fore-and-aft direction it is some circumferentially to stagger in processing drum each other, that is, the circumferential position of processing drum is arranged differently mutually each other.
Promptly; In a plurality of second spirals 302 on same second spiral 302; Relation for the adjacent independent process tooth 315 of fore-and-aft direction; With respect to independent process tooth 315 of certain week configuration of first spiral 301, see in the front of processing drum 31 at the roughly independent process tooth 315 of week back configuration of first spiral 301, be arranged in processing drum direction of rotation upstream side in processing drum with circumferentially keeping certain spacing bias.Thus, these see in the front of processing drum 31 that at the adjacent independent process tooth 315 of fore-and-aft direction the mode only there to be a mutual part to repeat disposes each other.
On this basis; These handle on the tooth 314 repeated configuration towards the rear at the adjacent independent process tooth 315 of fore-and-aft direction at spiral each other, not arrange with the mode that the linearity of the parallel axes of processing drum 31 forms row at fore-and-aft direction along one second spiral 302.One row of 315 groups in the independent process tooth of this fore-and-aft direction according to the quantity of second spiral 302 in circumferentially multiple row configuration at regular intervals of processing drum.Like this, the outer peripheral face in body portion 311, the installation site of spiral processing tooth 314 and each independent process tooth 315 is by first spiral 301 and 302 decisions of second spiral.
In addition; In this embodiment; The spirals of first spiral of the installation site through will being used to determine the independent process tooth and the spirals of second spiral are made as necessarily; Make at the leading section interval each other of the adjacent independent process tooth of above-mentioned fore-and-aft direction to equate, but also can be through in any range of the fore-and-aft direction of body portion, both sides or a side's spirals is changed than the spirals in other scope is big or little.
In addition; In this embodiment, make at the leading section interval each other of the adjacent independent process tooth of the coiling direction of first spiral to equate, but also can make it to shorten, make it to increase through a part that is omitted in the independent process tooth that the first screw winding direction arranges through between the adjacent independent process tooth of the coiling direction of first spiral, appending configuration independent process tooth.
And; Under this situation; For female part 32; Forming like above-mentioned sieve nest in the supporting structure of sheet 322A; A plurality of sieve nests form sheet 322A see in the front of processing drum 31 shown in figure 16, certain sieve nest form sheet 322A and with respect to this sieve nest form interval that sheet 322A adjacent sieve nest of bending direction that framework forms sheet 321F, 321B in front and back forms sheet 322A with the leading section of certain independent process tooth 315 of processing drum 31 and with respect to this independent process tooth 315 at the interval of the leading section of the adjacent independent process tooth 315 of fore-and-aft direction in processing drum circumferentially for to arrange with the mode of degree.
Therefore; Certain sieve nest forms sheet 322A and certain independent process tooth 315 and together is disposed at the first straight line L1 that extends to the processing drum radial outside from the pivot of processing drum 31 when going up, and forms the adjacent sieve nest of bending direction that the framework of sheet 322A in front and back form sheet 321F, 321B with respect to certain sieve nest and forms sheet 322A and also circumferentially depart from predetermined angular to second straight line L2 of processing drum radial outside extension on respect to the first straight line L1 in processing drum with being disposed at from the pivot of processing drum 31 at the adjacent independent process tooth 315 of fore-and-aft direction with respect to certain independent process tooth 315.
Promptly; When certain sieve nest forms sheet 322A and disposes with the opposed mode of leading section with certain independent process tooth 315 of processing drum 31, form the adjacent sieve nest of bending direction that the framework of sheet 322A in front and back form sheet 321F, 321B with respect to certain sieve nest and form sheet 322A also to form with disposing in the opposed mode of leading section of the adjacent independent process tooth 315 of fore-and-aft direction with respect to certain independent process tooth 315.In other words, each other adjacent sieve nest form sheet 322A with the leading section of each adjacent independent process tooth 315 of the fore-and-aft direction of processing drum 31 simultaneously opposed mode dispose and form.
At this moment; Front in processing drum 31 is seen; Each independent process tooth 315 of processing drum 31 and set at the circumferential interval of processing drum of the adjacent independent process tooth 315 of fore-and-aft direction with respect to this independent process tooth 315 as previously mentioned roughly the samely; So each sieve nest forms sheet 322A and forms the circumferential interval of processing drum that the adjacent sieve nest of bending direction that the framework of sheet 322A in front and back form sheet 321F, 321B forms sheet 322A with respect to this sieve nest and sets also roughly the samely.Thus, a plurality of sieve nests formation sheet 322A equally spaced arrange at the framework formation sheet 321F of front and back, the bending direction of 321B.
In addition; In this embodiment; Forming sheet interval each other the same with the leading section interval each other of independent process tooth with sieve nest is that equally spaced mode is arranged a plurality of sieve nests formation sheets; But corresponding to the change at the leading section interval each other of independent process tooth, sieve nest forms sheet interval each other and also can form the sheet each interval with the sieve nest of a part and become big, and remaining sieve nest forms the mode unequal interval ground arrangement that sheet interval each other diminishes.
As stated; Following formation is processed by the threshing portion 30 of combine 1: between the outer peripheral face of independent process tooth 315 and body portion 311, also possess to the outstanding spiral of processing drum radial outside and handle tooth 314; Handle tooth 314 along first spiral, 301 configuration spirals, this first spiral 301 is consistent with these processing drum 31 axis.
Thus, when threshing operations, it is on the straw that each independent process tooth 315 that one second spiral 302 is configured to row at fore-and-aft direction in processing drum 31 upper edges acts on the threshing object that is transferred in the past with being separated with the time difference in order.Therefore, can suppress straw and be wound in rope form.Therefore, threshing operations smoothly can be carried out, the raising of threshing performance can be realized.And independent process tooth 315 as above-mentioned acting on the straw are so can alleviate biography to the overload of the moment of processing drum 31, noise and the generation vibration that processing drum 31 produces.Therefore, also can cosily improve the sensation of taking of the combine 1 that possesses this threshing portion 30.
And; Threshing portion 30, the female part 32 of combine 1 are processed following formation: the front in processing drum 31 is seen, forms sheet 322A with these adjacent each other sieve nests and forms sheet 322A interval each other with the adjacent sieve nest of bending direction that is set in sieve nest 322 in opposed mode of the leading section while of each adjacent independent process tooth 315 of the fore-and-aft direction of processing drum 31.
Thus; When threshing operations; Certain sieve nest of sieve nest 322 forms sheet 322A and independent process tooth 315 when opposed on female part 32; It is also opposed with independent process tooth 315 to form sheet 322A at the adjacent sieve nest of fore-and-aft direction, and these adjacent each other sieve nests form sheet 322A and always rotate with each independent process tooth 315 clamping straw.Therefore, straw can quicken the flow velocity of the straw between processing drum 31 and the female part 32 so that roughly certain speed is mobile.Therefore, threshing operations smoothly can be carried out, the raising of threshing performance can be realized.
In addition, in the threshing portion 30 of this combine 1, female part 32 also can constitute as follows, and it is described.
Shown in figure 17; In female part 32, being set up in parallel in processing drum circumferentially is that two of left and right directions are cut apart female part 320 so that part left framework that the right framework of the framework 321 of cutting female part 320 forms sheet 321R and part the framework 321 of cutting female part 320 on the right side on the left side and form sheet 321L face state of contact and link.Framework 321 as the above-mentioned formation of respectively cutting apart female part 320.
Also shown in Figure 18 (a); About cut apart the left framework that parts the framework 321 of cutting female part 320 on the right side in the female part 320, processing drum direction of rotation upstream side and form sheet 321L and have vertical 321La of portion and horizontal part 321Lb, form anti-L word shape with horizontal part 321Lb from the upper end of the vertical 321La of portion towards form the mode that sheet 322A side extends at the circumferentially adjacent sieve nest of processing drum.
Left side framework forms sheet 321L and forms sheet 321F binding in the right side and the preceding framework of its leading section, and the right side of portion and after-frame bodily form 321B in blocks links in its back-end.At this linking part, the vertical 321La of portion that left framework is formed sheet 321L is fastening with the left part that the framework of front and back forms sheet 321F, 321B, and the horizontal part 321Lb that left framework forms sheet 321L carries on the left part of framework formation sheet 321F before and after placing, 321B.
In addition, left framework form sheet 321L in its left side can with part the right framework of cutting female part 320 on the left side and form sheet 321R and engage.At this graft union, the vertical 321La of portion that left framework forms sheet 321L contacts with the vertical 321Ra of the portion face that parts the right framework formation sheet 321R that cuts female part 320 on the left side in the scope of front and back.This right side framework forms sheet 321R and left framework formation sheet 321L left-right symmetric constitutes much the samely.
And, pole shape parts 326 form in left framework sheet 321L the vertical 321La of portion right side side and horizontal part 321Lb under form sheet 322A with sieve nest and dispose abreast, the framework before and after being set up in forms between sheet 321F, the 321B.These pole shape parts 326 form the continuous mode in the right side of horizontal part 321Lb of sheet 321L to the right side of this horizontal part 321Lb with its right side outer peripheral face and left framework, promptly processing drum direction of rotation upstream side is outstanding some.Like this, form the adjacent sieve nest that is provided with on the sheet 321L with processing drum direction of rotation upstream side in left framework and form the opposed curved face part 327 of sheet 322A.But, replacements such as the enough cylinder-like parts of pole shape parts ability.
Perhaps, shown in Figure 18 (b), left framework forms the horizontal part 321Lb of sheet 321L at its left and right directions middle part, along axially being the broken curve that fore-and-aft direction extends to processing drum, removes end roughly bending at right angles towards the below of front and back.Like this, left framework forms the adjacent sieve nest that sheet 321R is provided with processing drum direction of rotation upstream side and forms the opposed bight 328 of sheet 322A.
Promptly; It constitutes female part 32, about cut apart in the female part 320, processing drum direction of rotation upstream side part on the right side the framework 321 of cutting female part 320, be positioned at and the left framework that parts the binding side of cutting female part 320 on the left side forms sieve nest formation sheet 322A opposed curved face part 327 or the bight 328 adjacent with processing drum direction of rotation upstream side are set on the sheet 321L.
Thus; During threshing operations; Cut female part 320 from processing drum direction of rotation upstream side downstream during side flow by the straw of processing drum 31 threshings parting on the right side; Contact with curved face part 327 or bight 328, be difficult to lash and form on the sheet 321L, particularly on its horizontal part 321Lb in the left framework of framework 321.Therefore, when straw is the soybean straw, can reduce the dirty grain of soybean.In addition, the straw lash be can suppress to produce and the obstruction of cutting apart female part 320 (female part 32) that causes on the sheet 321L, the straw lash forms the threshing portion 30 that causes on the sheet 321L in right framework integral body obstruction formed in left framework.The raising of the operating efficiency in the time of consequently, can realizing threshing operations.
Utilizability on the industry
The threshing portion of combine of the present invention so can carry out threshing operations smoothly, can realize the raising of threshing performance because straw can not be wound in rope form, so useful on the industry.
