Abstract

The utility model discloses a combined multifunctional thresher combining threshing with sorting for corn and sunflower. The utility model has the advantages of simple structure and strong applicability. Because of the structure characteristics of a threshing assisting device, the advantages of a concave plate sieve and the action of secondary sorting, the utility model can effectively realize the purpose combining threshing with sorting; thus, sorting husks, impurities and seeds are separated.

Description

Multifunctional corn sunflower thresher

Technical field:

The utility model belongs to a kind of crops thresher machine, especially to a kind of multi-functional mechanical of corn, sunflower threshing.

North scape technology:

Existing corn sunflower thresher; all adopting bottom semicircular screen cloth and mesh is circle and bar shaped; and by be arranged on the sieve in the threshing axle on the tooth plate that takes off carry out operation; and take off tooth plate guide effect is arranged all generally; force crop to be discharged, a lot of crops are blocked at mechanical afterbody, the ability through threshing to mechanical afterbody; cause with foreign material can for so a lot of seeds and mix the chance that one discharges, have the defective that to clean the assorted value in the seed simultaneously.

The utility model content:

The utility model provides a kind of threshing and takes off a kind of combined type thresher that choosing combines, and it can overcome above-mentioned deficiency of cleaning effectively.

The purpose of this utility model is implemented by following technical scheme: it comprises the threshing axle, helps and take off device, concave grate, slide plate, take off the separating mechanism of choosing tube and transmission and take off screening device.Its structural feature is: described separating mechanism; Comprise that with cover and concave grate be interior circle, be positioned at the charging aperture right side, and help and take off device in peripheral sheathed one of threshing axle and threshing tooth, describedly help that to take off device be to make a kind of hollow cone bar shaped grid with metal material, and with cover and concave grate in the circle outer wall fix, its taper is protruded to mechanical caudal directions, and can play the repetition flailing action of blocking, take off the peripheral bottom of device and threshing tooth and establish a flute profile concave grate described helping, and fix with frame, its wall of described concave grate is provided with microscler mesh, is convenient to microscler sunflower seed and spills, below the preceding methods, rack of described concave grate, an if C type coaming plate, its bottom is positioned in the middle of the two side, establishes a downward-sloping plane slide plate, the gradient of described slide plate, seed can be glided downwards in the above fast to be as the criterion, a splayed baffle plate is established at the middle part on described slide plate, and the plate face height of described baffle plate all can stop the seed that slides on its slide plate to both sides downwards and is as the criterion.

The described screening device that takes off: this device is arranged on the preceding bottom of separating mechanism; be positioned at centre, two side and slide plate bottom and establish a cylindric choosing tube that takes off; described its outer wall of choosing tube that takes off is provided with circular mesh; be provided with in it and take off choosing axle and take off and select plate; the described two ends, bottom of choosing tube of taking off are near the place, two side; be provided with two seed inlets, and be connected, establish a discharging opening above leaning in the described preceding middle part of choosing tube of taking off with two, baffle plate lower end.

The utility model has the advantages that:

The repetition threshing of blocking at machinery middle part, making it play corn purifies and could spill from helping to take off in the device grid, microscler mesh with regard to concave grate, being beneficial to foreign material isolates, be convenient to the effect that corn, sunflower seed spill, the secondary through taking off the choosing tube takes off choosing again, makes the assorted value in its seed, it is broken to select the plate rubbing to take off by taking off of rotation, selects the drum outer wall mesh to spill to taking off.

The explanation of accompanying drawing drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a cut-away view of the present utility model;

Fig. 3 is for slide plate of the present utility model and take off a choosing tube connection diagram;

Fig. 4 takes off the device schematic appearance for of the present utility model helping;

Embodiment:

As Fig. 1; 2; 3; shown in 4; comprise threshing axle 9; help and take off device 10; concave grate 12; slide plate 16 takes off the separating mechanism of choosing tube 6 and transmission and takes off screening device; its structural feature is: described separating mechanism comprises that with cover 2 and concave grate 12 be interior circle; be positioned at charging aperture 1 right side; and help and take off device 10 and help that to take off device 10 be to make a kind of hollow cone bar shaped grid with metal material in peripheral sheathed one of threshing axle 9 and threshing tooth 11; and with cover 2 and concave grate 12 in the circle outer walls fix; make its taper to mechanical afterbody to square protrusion; and can play the repetition flailing action of blocking; help and take off the peripheral bottom of device 10 and threshing tooth and establish a flute profile concave grate 12; and fix with frame 4; its wall is provided with microscler mesh; being convenient to microscler sunflower seed spills; methods, rack 4 is to divide into a C shape coaming plate 5 before the concave grate 12; a downward-sloping plane slide plate 16 is established in the middle of being positioned at two side 3 in its bottom; the gradient of its slide plate 16; seed can be glided downwards in the above fast to be as the criterion; a splayed baffle plate 13 is established at the middle part on the slide plate 16; two, lower end of its baffle plate 13 connects with the seed inlet 15 that takes off choosing tube 6 two bottom sides, and the plate face height of baffle plate 13 is that the seed that slides downwards on its slide plate 16 all can stop to both sides and is as the criterion.

The described screening device that takes off: this device is arranged on the preceding bottom of separating mechanism; be positioned at 3 centres, two side and slide plate 16 bottoms and establish a cylindric choosing tube 6 that takes off; take off choosing tube 6 outer walls and be provided with circular mesh; being provided with taking off of rotation in it selects axle 8 to select plate 14 with taking off; take off the two ends, bottom of choosing tube 6; be provided with two seed inlets 15 near 3 places, two side, and be connected, establish a discharging opening 7 above leaning in the described choosing tube 6 preceding middle parts of taking off with two, baffle plate 13 lower end.
