Abstract

The utility model relates to an agriculture machine, a thresher roller and threshing equipment thereto. The threshing equipment includes a shell with an air duct, a power transmission device, a thresher roller and a grain transporting device. The thresher roller is a totally enclosed cylinder made of sheet and two support sheets with center support bases are arrange in the roller. The axle of the roller is provided with a key slot. One terminal of the roller axle is connected with roller by the joint between the key slot and the support bases; the other terminal of the roller axle is arranged on the shell of the threshing equipment through a bearing. The threshing equipment made of the novel thresher roller in the utility model is small in size, and performs threshing more thoroughly. Rice ears and wheat ears are easier to discharge from machine so as not easy to occur clogging.

Description

Thresher drum and sheller unit thereof

Technical field:

The utility model relates to a kind of agricultural machinery and accessory thereof, particularly a kind of sheller unit and accessory thereof.

Background technology:

The common thresher drum that is used for paddy wheat thresher mostly is rare window formula greatly at present, mostly the fulcrum of cylinder is two supports, adopt the weak point of the thresher that the rare window formula of this kind thresher drum makes to be: 1, the spike of rice or the wheat head enter behind the thresher easily that the heave in cylinder is difficult for separating, and cause straw to discharge relatively difficulty of thresher; 2, because straw is difficult for discharging thresher, make short and small stalk increase, the impure increase of the cereal of results, separation circuit increases; 3, because straw is difficult for discharging, make the threshing space to increase, it is big that body volume becomes; 4, owing to open wide in the middle of the cylinder, the paddy after the threshing, wheat fall into centre of the drum easily, outside body is discharged in the axle center, cause waste.

The utility model content:

The technical problems to be solved in the utility model provides a kind of fully closed thresher drum, and the sheller unit above shortcomings part of sheller unit to overcome above-mentioned rare window formula thresher drum and to adopt this kind cylinder to make that adopts the fully closed thresher drum of this kind to make.

The technical scheme that solves the problems of the technologies described above is: a kind of thresher drum; comprise drum shaft, barrel and distribution threshing spike-tooth thereon; barrel one end is welded with fan propeller; described barrel is the totally-enclosed cylinder that a usefulness thin plate is made; be fixed with two gripper shoes of center band supporting seat in the barrel; keyway is arranged on the drum shaft; thereby an end of drum shaft is connected with barrel by keyway and supporting seat are fixedly connected, and the other end of drum shaft is useful on the bearings point and the bearings point of stationary thresher cylinder.

Further technical scheme of the present utility model is: a kind of sheller unit; comprise the shell, power and the transmission device thereof that have the air channel; thresher drum; send the paddy device; described thresher drum is the above-mentioned thresher drum of the utility model; its barrel is the totally-enclosed cylinder that a usefulness thin plate is made; be fixed with two gripper shoes of center band supporting seat in the barrel; keyway is arranged on the drum shaft; thereby an end of drum shaft is connected with barrel by keyway and supporting seat are fixedly connected, the other end of drum shaft by bearing fixing on the shell of sheller unit.

Because adopt technique scheme, the totally enclosed type thresher drum and the sheller unit of the utility model have following beneficial effect:

1, thresher drum is made totally enclosed type, makes the spike of rice or the wheat head do centrifugal motion along cylinder outer wall, and the chance that has increased the friction of the spike of rice or the wheat head and screen cloth makes threshing more thorough;

2, because cylinder is a totally enclosed type, the spike of rice or the wheat head can not twist on cylinder, discharge body easily;

3, cylinder is made totally enclosed type, has prolonged sieve and has beaten route, makes sheller unit smaller and more exquisite, and threshing is more thorough;

4, all at an end of cylinder, it is more smooth and easy outward that the spike of rice or the wheat head are discharged machine for the fulcrum of back-up roller, is difficult for taking place choking phenomenon;

5, because cylinder leans on an end of back shaft to be provided with fan propeller, produce the wind-force that blows to the back shaft other end when cylinder rotates, help the discharge of stalk.

Below, in conjunction with the accompanying drawings and embodiments the thresher drum of the utility model and the technical characterictic of sheller unit are further described.
