Abstract
The utility model discloses a stem pulling roller structure, and relates to the technical field of corn harvesters. The stem pulling roller structure comprises a stem pulling roller body, a connecting piece, a sleeve and a leading-in taper, wherein the stem pulling roller body is fixedly connected with the connecting piece and the leading-in taper; the stem pulling roller body is in an integral structure; a ridge of each tooth crest of the stem pulling roller body is in a fillet transition shape; the connecting piece is provided with a U-shaped opening groove; and the U-shaped opening groove is internally provided with a hard wearproof shaft bush. The stem pulling roller structure is simple in processing technique, reduces working procedures, improves the production efficiency, prolongs the service life of a stem pulling roller, and reduces the maintenance cost.
Description
Technical field
The utility model relates to the maize harvesting machine technical field.
Background technology
The version of present existing Maize harvesting machine is divided into the snapping bar formula and draws the stem roll-type.Draw the structure of stem roll-type to be divided into the four square tool formula again and six ribs are board-like, the board-like six block plates welding moulding of adopting of six ribs more.There is following problem in this kind preparation method: the welding operation is difficult to guarantee to draw the symmetry of stem roller crest line, and the crest line of weld is more coarse, is difficult for handling, and can directly influence the operation quality of the ceding of Taiwan.In addition, because need of work, draw the gap between the stem roller to need often to adjust, therefore draw the axis of stem roller and the axis of transmission case can present certain included angle, draw the contact point of stem roller rear end and casing link position that frequent variations can take place, cause the contact point meeting rapid wear of connector, service life is short, increases maintenance cost.
The utility model content
It is simple that technical problem to be solved in the utility model provides a kind of processing technology, long service life draw the stem roll structure.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of stem roll structure that draws, comprise and draw stem roller roll body, connector, sleeve and importing awl, described connector with draw stem roller roll body, draw stem roller roll body and import awl and be and fixedly connected, it is characterized in that: described to draw stem roller roll body be monolithic construction, and the crest line that draws the tooth top portion of stem roller roll body is round-corner transition shape.
Preferably, the described cross section of stem roller roll body that draws is close-shaped for what wait slab to constitute, and tooth portion is overlapping.
Preferably, drawing the cross section of stem roller roll body is hexagon.
Preferably, described connector is provided with the U-shaped open slot, in the U-shaped open slot axle sleeve is set.
Preferably, described axle sleeve and connector cooperation place are the plane, and axle sleeve adopts the hard, wear-resistant material.
The beneficial effect that adopts technique scheme to produce is:
The stem roller roll body that draws of the present utility model is monolithic construction, the crest line that draws the tooth top portion of stem roller roll body is round-corner transition, and is smooth mellow and full, and symmetry is good, need not post-processed, processing technology is simple, enhances productivity, and the hard, wear-resistant axle sleeve is when drawing the stem roller to rotate, make the friction transfer of connector and bearing pin between bearing pin and the axle sleeve, reduce the wearing and tearing of drawing the stem roller, directly prolonged the service life of drawing the stem roller, reduced maintenance cost.

Fig. 3 is the A-A cutaway view of Fig. 1.
Among the figure: 1-draws stem roller roll body, 2-axle sleeve, 3-bearing pin, 4-connector, 5-sleeve, 6-power transmission shaft.
7-imports awl.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the part sectioned view that draws the stem roll structure, and Fig. 2 is the part sectioned view of an embodiment of the present utility model, and Fig. 3 is the A-A cutaway view of Fig. 1.
As shown in Figure 1 draw the stem roll structure, comprise and draw stem roller roll body 1, connector 4, sleeve 5 and importing awl 7, described connector 4 is and fixedlys connected with drawing stem roller roll body 1, draw stem roller roll body 1 and import awl 7, the described stem roller roll body 1 that draws adopts shaping equipment, make monolithic construction, so the cross section that draws stem roller roll body 1 that forms is close-shaped by waiting slab to constitute, and cross section is hexagon, and tooth portion is overlapping, the crest line of its tooth top portion is round-corner transition shape, smooth mellow and full, symmetry is good, in the described connector U-lag axle sleeve is set.
An embodiment as shown in Figure 2, this draws stem roll structure outside that housing is housed, housing will draw stem roll structure and transmission case to be assembled together by bolt, draw stem roller roll body 1 and connector 4 to weld together, connector 4 is provided with the U-shaped open slot, bearing pin 3 inserts in the installing hole of power transmission shaft 6, the two ends of bearing pin 3 cooperate with axle sleeve 2 endoporus, axle sleeve 2 is contained in the open slot of connector 4, axle sleeve 2 is the plane with connector 4 cooperation places, belong to tight fit between axle sleeve 2 and the connector 4, axle sleeve 2 adopts the hard, wear-resistant material, power transmission shaft 6 by bearing pin 3 to drawing stem roller roll body 1 transferring power, two ends and the big matched in clearance of axle sleeve 2 endoporus of while bearing pin 3, thereby between bearing pin 3 and the axle sleeve 2, axle sleeve 2 adopts wear-resistant material, connector 4 rapid wears when having solved power transmission with the friction transfer between original bearing pin 3 and the connector 4, draw the stem roller to change the problem of difficulty.
Adopting the crest line that draws stem roller roll body tooth top portion of this kind structure is round-corner transition shape, and smooth mellow and full, symmetry is good, and processing technology is simple, has reduced operation, has improved production efficiency, has prolonged the service life of drawing the stem roller, has reduced maintenance cost.
