Abstract
The utility model relates to the technical field of agricultural machinery, in particular to a combine harvester which comprises a rack, a cutting platform, a conveying chute, a vibrating screen, a front threshing room and a rear threshing room, wherein the front and the rear threshing rooms are positioned on the frame and distributed at the front part and the rear part; each threshing room comprises a top cover, an axial flow roller and a concave screen; roller shafts are arranged in the two axial flow rollers, and are mounted on the rack through bearing seats; and each threshing room comprises a feed port and a discharge port, and the discharge port of the front threshing room is opposite to the feed port of the rear threshing room. The combine harvester is characterized in that the front and the rear threshing rooms are vertically distributed, and the front and the rear axial flow rollers are vertically distributed. In the combine harvester, the flow paths of materials in the threshing rooms are more reasonable, the flow of the materials is smoother, the threshing rate is high, the breakage rate is low, the discharge status of straw is good, and the straw blockage in a machine body can be avoided.
Description
(1) technical field:
The present invention relates to agricultural machinery technological field, especially a kind of combine.
(2) background technology:
At present, the combine of crops such as harvesting paddy and wheat includes only a threshing cylinder with teeth usually, crops by ceding of Taiwan results enter threshing chamber through delivery chute, while threshing cylinder with teeth high speed rotating, under the acting in conjunction of threshing cylinder and concave grate, the grain of mature and plump is split away off from straw.The combine of this class formation is not ideal aspect threshing performance.Immediate for this reason prior art Chinese patent CN02288324.X discloses the patent that name is called the sheller unit of combine, Chinese patent 200920021696.0 discloses the patent that name is called the twin-roll rice combine, these two patents have all increased a threshing chamber that comprises threshing cylinder with teeth, two threshing chambers are front and back and column distribution, the threshing cylinder that increases newly parallels with former threshing cylinder, straw after threshing cylinder carries out threshing the preceding, enter after threshing cylinder carry out threshing, by increasing threshing cylinder, prolonged the effective travel of threshing, improved threshing performance, the fine percentage of damage of having taken into account has been avoided high percentage of damage simultaneously.The deficiencies in the prior art are that material is unreasonable at the circulation route of threshing chamber, and the smooth and easy circulation of material is not good, and power consumption is big, need be improved.
(3) summary of the invention:
The present invention aims to provide a kind of threshing performance height that overcomes above-mentioned deficiency, material circulation combine more smoothly.
Technical solution of the present invention is as follows:
Combine, comprise frame, the ceding of Taiwan, delivery chute, console, be positioned at distribute before and after being on the frame preceding threshing chamber with at the back threshing chamber, each threshing chamber all includes top cover, axial-flow type drum and the concave grate that has deflector, two axial-flow type drums all are installed on the frame by bearing block, two threshing chambers have feeding mouth and outlet respectively, at the outlet of preceding threshing chamber with relative at back threshing chamber feeding mouth, it is characterized in that: described preceding threshing chamber with the back threshing chamber be in vertical distribution, preceding axial-flow type drum with the back axial-flow type drum be in vertical distribution.
Further technical scheme is:
Above-mentioned preceding threshing chamber with the back threshing chamber, preceding axial-flow type drum with in back axial-flow type drum T-shaped vertical distribution, promptly the outlet of preceding threshing chamber with at back threshing chamber feeding mouth corresponding to medium position at preceding threshing chamber.
The technical scheme in another step is:
Above-mentioned at preceding threshing chamber and at the back threshing chamber, at preceding axial-flow type drum and in the L-shaped vertical distribution of back axial-flow type drum.Promptly the outlet of preceding threshing chamber with back threshing chamber feeding mouth corresponding to preceding threshing chamber with respect to opposite side position at the feeding mouth of preceding threshing chamber.
Crops by ceding of Taiwan results enter at preceding threshing chamber through delivery chute, threshing cylinder (at preceding axial-flow type drum) high speed rotating, its spike-tooth constantly impacts the straw that is fed, the grain of mature and plump is split away off from straw, straw is made axial flow at the effect lower edge of top cover deflector threshing cylinder simultaneously, be transported to outlet at preceding threshing chamber, under centrifugal action, be thrown into the back threshing chamber from back threshing chamber feeding mouth, threshing cylinder (at the back axial-flow type drum) high speed rotating at the back threshing chamber, its spike-tooth constantly impacts the straw threshing once more that is fed, and grain splits away off from straw, and the straw after the threshing is from discharging at the outlet of back threshing chamber.
In the technical solution of the present invention, T-shaped or the L shaped front and back of two threshing chambers vertical distribution, prolonged the effective travel of threshing, improved threshing performance, the fine percentage of damage of having taken into account of while, material is more reasonable at the circulation route of threshing chamber, and the material circulation is more smooth and easy, reduce power consumption, realized goal of the invention easily.
When the vertical distribution of the L-shaped front and back of two threshing chambers, the effective travel of threshing obtains farthest to prolong.
Further technical scheme is again:
Described have the transition passage that is bent to form by ganoid rebound at the outlet of preceding threshing chamber and in threshing chamber feeding mouth junction, back.
Above-mentioned transition passage can be taper type or half taper type.
Field trial proves that the present invention gathers in not only threshing performance height, and percentage of damage is low, and straw circulation property is good, and straw is discharged in order, the interior no straw of body stops up.
(4) description of drawings:
Below with reference to drawings and Examples the present invention is described in further details:
Accompanying drawing 1 is the outline drawing of the embodiment of the invention.
Accompanying drawing 2 is the vertical view of accompanying drawing 1 illustrated embodiment.
Accompanying drawing 3 is in accompanying drawing 1 illustrated embodiment, after top cover is raised preceding threshing chamber with the back threshing chamber structural representation (overlooking).
Each sequence number is respectively in the accompanying drawing: 1, the ceding of Taiwan, 2, delivery chute, 3, console, 4, at preceding threshing chamber, 5, in back threshing chamber, 6, the chassis, 7, at preceding axial-flow type drum top cover, 8, at preceding axial-flow type drum, 9, at back axial-flow type drum top cover, 10, at the back axial-flow type drum, 11, concave grate, 12, rebound.
