Abstract
The utility model discloses a threshing machine, comprising a machine frame, a feeding platform, a rotary drum, a concave plate, a machine cover, a straw-discharging machine, a suction blower, a remains-recovering/cleaning screen, an elevator, a grain box and a transmission mechanism. The rotary drum and the blower are divided into two bodies, and a medium shaft is arranged between the rotary drum and the blower; an idle wheel arranged on the medium shaft can be changed anytime, so as to adjust the rotary speed of the blower and increase the cleaning rate of kernels. With a chain-rack type conveying device which has favorable sealing performance, the feeding platform is provided with a cleaning device, a chain-lift bucket type elevator and a running device. The cleaning plant can automatically recover the remains; the running device is convenient to run. The utility model reduces middle operating course, increases working efficiency, improves operating environment and guarantees operators' safety.
Description
Technical field
The utility model relates to a kind of agricultural machinery, is specifically related to a kind of grain separator.
Background technology
The thresher pattern is various to cut both ways; general axial-flow thresher; drum spindle and blower fan are with speed, and blower fan wind-force is not enough, influences thresher and cleans rate; demand along with market; the raising of planting technology and the improvement of auxiliary facility, the enhancing of peasant market consciousness designs a kind of needs that can satisfy market; mating power is suitable, both practical, simple again new thresher.
The utility model content
The purpose of this utility model is to provide a kind of raising grain cleaning rate, reduces cleaning loss, improves the thresher of operating environment.
The technical solution of the utility model is: this thresher is by frame, the feeding platform, cylinder, notch board, cover, blower fan, assorted surplus separator, sorting screen, tanker, elevator and transmission mechanism are formed, drum spindle is arranged on the frame by bearing, the cylinder top is provided with cover, notch board is arranged on the cylinder below, the cylinder side is provided with two air channels blower fan, between blower fan and the cylinder stub is set, idle wheel is set on the stub, assorted surplus separator is set between blower fan and the cylinder, sorting screen is arranged on the notch board below, and sorting screen constitutes double-deck sieve nest by flake sieve sheet and wire gauze sieve sheet, is driven by eccentric rod mechanism; The feeding platform is totally-enclosed automatic feeding platform, and feeding is provided with the sleeve-barrel roollr chain of scraper plate in the platform, and elevator is fixed on the frame tail end by support, in the sleeve-barrel roollr chain is set, the elevator exit is provided with tanker.
The utility model feeding platform adopts the chain-and-harrow type conveying plant of good seal, does not run grain, and feeding speed is fast; Cylinder and blower fan are divided into two bodies, and the centre is provided with stub, when crop overdrying or wet excessively when being unfavorable for cleaning, and the idle wheel on the interchangeable stub, thus adjust rotation speed of fan, improve grain cleaning rate; Flake sieve sheet is adopted in the two air channels of two sieves, top sieve, makes the unlikely slotting compass screen surface of foreign material, and it is fully separated; Disconnected fringe and sucking-off seed foreign material are admitted to assorted surplus separator and are recovered to cylinder and take off again again, have thoroughly solved the problem of grain clean rate and cleaning loss, and chain promotes the bucket type elevator, auto-filling, and solved belt creep, defective that the operation fault is many; The road wheel conveniently moving is set, can reduces the intermediate transportation link in farm work.The utility model is rational in infrastructure, mechanism's compactness, and simple to operate, easy to maintenance, serviceability is reliable.

Fig. 1 and Fig. 2 are respectively the utility model thresher front view and left view.
Embodiment
As shown in the figure; the utility model thresher is by frame 10; feeding platform 31; cylinder 7; notch board 9; cover 14; straw outlet; blower fan 27; assorted surplus separator 15; sorting screen 6; tanker 18; elevator 19 and transmission mechanism are formed; the frame below is provided with road wheel 2; drum spindle is arranged on the frame 10 by bearing; the cylinder top is provided with cover 14; notch board 9 is arranged on cylinder 7 belows; the cylinder side is provided with blower fan 28, and blower fan is two air channels 26; 28, stub 29 is set between blower fan and the cylinder; idle wheel is set on the stub; blower fan upper outlet 20 communicates with assorted surplus separator 15 by assorted surplus transport tube 16, and assorted surplus separator 15 is arranged on the cylinder top, and a side is provided with straw outlet.Sorting screen 6 is articulated in the notch board below by suspension rod, and sorting screen constitutes double-deck sieve nest by flake sieve sheet and wire gauze sieve sheet, is driven by eccentric rod mechanism; Feeding platform 31 is fixed on cylinder one end by support 30, be provided with the sleeve-barrel roollr chain and the feeding belt pulley 32 of scraper plate in the totally-enclosed automatic feeding platform, elevator 19 is fixed on the frame tail end by support, in the sleeve-barrel roollr chain is set, tanker 18 is arranged on the elevator exit.
The utility model transmission mechanism, thresher hitch frame 1 is connected with the tractor-drawn ring, and power take-off 3 is connected with the tractor rear axle power take-off by the universal joint shaft joint.Power-take-off pulley 4 drives cylinder main pulley 12 and rotates, and eccentric driving wheel 11 and feeding platform driving wheel 13 are equipped with in the main pulley outside, and feeding platform driving wheel 13 is passed to eccentric wheel 5 by eccentric driving wheel 11 with power, makes sorting screen 6 normal operations.Cylinder main pulley 12 is coaxial with main shaft afterbody negative pulley wheel 24, make cylinder normal operation while negative pulley wheel drive blower fan main pulley 25 by the idle wheel on the stub 29, drive the elevator driving wheel 22 coaxial simultaneously, make the blower fan normal operation drive elevator upper belt pulley 17 simultaneously and make the normal operation of elevator parts with it.
The course of work: crop is dropped in the feeding platform, crop is sent into threshing cylinder 7 and carries out threshing under the effect of feeding chain of stations bar and scraper plate, crop is rubbed down at the strike and the notch board 9 of spike-tooth, plate tooth, seed and the assorted surplus sorting screen 6 that falls into, cane is by outside the straw outlet eliminating machine, seed separates with assorted surplus top sieve through shake, seed falls into down sieve, assorted surplus clever shell is transported to blower fan and is sent to assorted surplus separator 15 and makes assorted surplus clever shell be discharged from outside the machine through the effect of air-flows, and the disconnected fringe of seed is admitted to cylinder and takes off again.Under sieve seed and be transported to down and sift out the grain mouth and enter elevator 19 and rise to tanker and pour in the bag then.
