Abstract

The utility model discloses a wheat thresher which belongs to agricultural machinery and is used in the process of wheat threshing. The wheat thresher is composed of a whitening cylinder, a propelling blade, a top cover, a threshing board, a concave plate, etc. The whitening cylinder operates in a continuous kneading and spiral propelling mode and is capable of being used through being matched with various cleaning mechanisms, in this way, the purpose of once completing the process of threshing, rolling and winnow is achieved, and the labour intensity is also reduced. Time saving and energy source saving are more than 50%.

Description

Wheat thresher

The wheat thresher belongs to farm machinery.

No matter general wheat thresher adopts any threshing mode, and threshing performance only reaches about 97%, and only wheat is played flailing action, then can not grind straw and become grass.And the most of wheet-producing areas of China; owing to feed livestock; also need wheat straw is ground into forage grass; (wheat straw stone roller stoking) so, common thresher then can not satisfy these needs, after peasants have to take off wheat with thresher; grind wheat straw again with animals or tractor etc. again; like this, not only taken a lot of work, time-consuming, but also polyvoltine money, have more power, and also need carry out cure process to the place.So quite a few peasant without thresher, and changes the stone roller method of threshing wheat with original threshing ground in the summer harvest, carrying out manual labor heavy.

The purpose of this utility model, be to provide one simple to operate, work efficiency is high and disposablely finish threshing, grind careless double-acting thresher, the stone roller mode is changeed and to the cure process requirement in place in the threshing ground that wheat and cereal is fundamentally eliminated fall behind for thousands of years.

The novel task of this use realizes by following approach.

Reach optimum state for making to take off to grind, take off to grind and adopt roller to add the method that helical blade advances.And be provided with in the top cover and fixedly take off plate, (the thresher structure was identical as cylinder-concave clearance, shell and other were same) wheat straw advances interior walking crosswise.This can make wheat extended stroke in taking off the stone roller process rub repeatedly.Reach not only totally but also fast and be not afraid of obstruction.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Below in conjunction with this use of description of drawings novel concrete structure and operation principle.

This structure comprises a feeding mouth 1, loam cake 3, fixedly takes off plate 4, roller 5, screw propulsion blade 6, twill bar 7, notch board 8.

Its operation principle is: roller 5 is through the external force driven rotary, wheat enters by arrow 2 through feeding mouth 1, by twill bars 7 all on the roller 5 with notch board 8, fixedly take off plate 4 and carry out threshing, roller 5 carries out roller with the inwall that fixedly takes off plate 4, notch board 8 again and grinds, advance by helical blade all on the roller 56 simultaneously, form threshing, roller stone roller, advance and carry out synchronously.

The horizontal sextant angle β of the pitch angle alpha will of helical blade 6 and twill bar 7 does not wait, can be relatively or in the same way, and it is unlikely and wheat straw is flowed out easily along spiral and influences the formation of wheat straw.Like this, wheat straw falls out at another side in interior several circles back of rubbing, and can become grass, and wheat also can purify fully.

Among the figure *-wheat straw zero-wheat △-wheat husk, broken grass they each fly out in the direction of arrows.

Novel and the existing threshing of this use is ground the technology of beating and is compared, when province is arranged, laborsaving, economical, improve work efficiency more than 50%, the rate of purifying reaches 100%, support the use with various dressing mechanisms, can make wheat and cereal crops take off, grind, raise once and finish, alleviated widely labour intensity, liberated and developed the advantages such as productivity.

Claims (3)

1, the wheat thresher has a stone roller that takes off that is loaded on center between loam cake 3 and the notch board 8, advance to be the roller assembly of one, it is characterized in that this assembly is made up of roller 5, screw propulsion sheet 6, twill bar 7.

2, thresher according to claim 1 is characterized in that having on the roller 5 screw propulsion sheet 6 and is in the same place in one or rivet welding for casting with twill bar 7.

3, thresher according to claim 1 and 2 is characterized in that:

1. the pitch angle alpha will of screw propulsion sheet greater than 0 ° less than 90 °;

2. the horizontal sextant angle β of twill bar 7 can be between 0 ° to 90 °.
