Description
Technical field
The utility model belongs to machinery manufacturing technology field, relates to a kind of grain harvest machinery.
Background technology
At present, domestic combine generally partly is made up of transmission system, induction system, threshing system, cleaning and sorting system etc.Its cleaning and sorting system is positioned at the back of threshing system, finishes the separation to the cylinder emersion object, to obtain clean seed.Because existing cleaning and sorting system of harvester adopts screen box to clean, cause the problem that has following four aspects: the one, wheat is when full maturity or air humidity are not big, though open the top sieve aperture fully, wheat and Mai Pi still easily stop up screen box and cause the wheat whereabouts not smooth; The 2nd, when the crop weeds are too much, cause easily and take off the screw feeder obstruction again, had a strong impact on the operating efficiency of grain header; The 3rd, screen box must often be shut down between operational period and be carried out the order of classes or grades at school cleaning, to remove the awn of wheat and cane foreign material between the sieve sheet, influences the operating efficiency of grain header; The 4th, the high yield wheatland is big for going into amount, because the amount of jitter of sieve is limited up and down, the speed of cleaning does not catch up with feed quantity, causes wheat and Mai Pi cluster to occur easily, and formation is pressed from both sides grain, leaked grain, the waste of formation grain resource.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model discloses a kind of cleaning and sorting system of harvester.By the effect of break-in wind-force, adopt chain gear transmission and several decomposition baffle plate, wheat and Mai Pi are carried out separating for several times, reach and prevent the purpose of pressing from both sides grain, leaking grain, increasing work efficiency and reduce production costs.
The technical solution of the utility model is to realize like this, cleaning and sorting system of harvester transmission system, induction system, each part structure of threshing system are same as the prior art, its selected part by paddy feeding port slide plate, loose axle, base plate, carry the grain screw feeder, decompose plate, gripper shoe, the plate that drops, break-in wind axis, blighted grain decomposition plate, portable plate, casing, fan blower, take off screw feeder again and form.The paddy feeding port slide plate is located at the eccentric lower left of moving sieve, is installed in the top of loose axle at an angle by two rectangular slabs; Loose axle is connected with casing; Carry the top that the grain screw feeder places the base plate recessed joint, be connected with casing; The break-in wind axis is located at the lower left of loose axle, is connected with casing, and the break-in wind axis is a helical structure, on the axle flight is set; Base plate is a rectangle bent plate, is connected upper left quarter and casing welding by bolt with fan blower; Slotted hole is set on the portable plate, decomposes plate and base plate hinged; Gripper shoe is welded with base plate and decomposition plate respectively; Plate and the blighted grain decomposition plate that drops is the thin plate that is provided with rectangular opening, is overlapped on the casing; Take off screw feeder again above the base plate recessed joint; Also be welded with loose net on the loose axle.
Good effect of the present utility model is: watering and separation procedure adopts the effect of wind-force fully, utilizes baffle plate to change wind direction, reaches and cleans purpose, safety, environmental protection; The cancellation screen box, structure is simpler, and equipment cost reduces, and prolong service life; Solved the screen box blocking problem fully, increased the feed quantity in the unit interval greatly, made the operating efficiency of combine improve nearly one times, fuel consume saves 50%; Clean by the secondary that takes off screw feeder realization wheat again, it is almost nil to leak grain, has improved peasant's increasing both production and income greatly.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model front view
Fig. 3 is the utility model shifting wind axle construction schematic diagram;
1 paddy feeding port slide plate among the figure, 2 loose axles, 3 base plates, 4 are carried grain screw feeder, 5 and are decomposed plates, 6 gripper shoes, 7 and drop that plate, 8 break-in wind axises, 9 blighted grains decompose plate, 10 portable plates, 11 take off screw feeder, 12 casings, 13 fan blowers, 14 induction systems, 15 threshing systems, 16 moving sieve eccentric wheels, 17 row wheat skin mouths, 18 loose nets, 19 cedings of Taiwan, 20 car bodies, 21 helical blades, 22 transmission systems again.
As shown in the figure; The utility model transmission system (22), induction system (14), threshing system (15) are identical with the prior art structure, its cleaning and sorting system by paddy feeding port slide plate (1), loose axle (2), a base plate (3), carry grain screw feeder (4), decompose plate (5), gripper shoe (6), the plate that drops (7), break-in wind axis (8), blighted grain are decomposed plate (9), portable plate (10), casing (12), fan blower (13), take off screw feeder (11) again forms.Paddy feeding port slide plate (1) is installed in the top of loose axle (2) at an angle by two rectangular slabs, break-in wind axis (8) is in the lower left of loose axle (2), break-in wind axis (8) and loose axle (2) are installed on the casing (12), break-in wind axis (8) is symmetrical arranged helical blade (21), and helical blade (21) employing waits the money steel plate to be welded on the break-in wind axis (8); Base plate (3) is a rectangle bent plate, is connected by bolt with fan blower (13), welds with casing (12); It is hinged with base plate (3) to decompose plate (5); Gripper shoe (6) is welded with base plate (3) and decomposition plate (5) respectively; Plate (7) and the blighted grain decomposition plate (9) that drops all has the thin plate of several rectangular openings to be overlapped on the casing (12).Be spirally connected with the decomposition plate; Row's wheat skin mouth (18) is a crooked metal sheet, and loose net (19) is a gauze; Car body (20), transmission system (22), carry grain screw feeder (4), take off screw feeder (11) again, moving sieve eccentric wheel (17) is all same as the prior art.
During work, not separated wheat arrives cleaning and sorting system by threshing system, drop on the loose axle through the paddy feeding port slide plate, the rotatory force that loose axle is gone up loose net is broken up the whereabouts wheat, the clean wheat of a part is directly fallen on the base plate, be transported to silo through carrying grain screw feeder and transport tube, the wheat skin is then discharged by row wheat skin mouth; Another part does not separate clean wheat then because the effect of fan blower is blowed to plate and the portable plate of dropping, and falls into through the hole on it and takes off again in the screw feeder, through the secondary threshing, slides into and carries the grain screw feeder, is transported to silo through carrying grain screw feeder and transport tube.
