Problems solved by technology

[0002] The universal threshing machine used for threshing corn, rice and wheat is equipped with a roll for feeding in the feed port of the machine body. The common roll is generally a helical rack with a one-way helical rack. When the thresher is running, because the spiral rack is in a one-way spiral state, the rolled billets will gradually accumulate on both sides, which will cause the winding roller and other parts to be stuck, resulting in abnormal operation and failure of the thresher. Frequent, directly affects the threshing efficiency

Embodiment Construction

[0010] attached figure 1 , 2 As shown in the embodiment: several helical rack plates 2 are distributed on the installed winding roller 1 , and each helical rack plate 2 is provided with a forward-rotation rack 3 and a reverse-rotation rack 4 . The helical rack plates 2 of several forward-rotation racks 3 and reverse-rotation racks 4 are distributed on the winding roller 1 in an intersecting and staggered manner.

[0011] figure 2 In the embodiment: the forward-rotation rack 3 and the reverse-rotation rack 4 are set alternately and alternately.

[0012] In the running state: the forward spiral rack 3 in the spiral rack plate 2 on the winding roller 1 will roll in the material, and it will deviate to one side during the rolling process. The reverse spiral rack 4 will wind up the material in the middle, and the next spiral The bar 2 keeps up with the forward rotation rack 3 and continues to be drawn inward. When the deviation occurs again, the reverse rotation rack 4 will pla...

Abstract

The invention provides a threshing machine provided with a positive and reverse spiral rack coiling roller. A plurality of spiral rack plates are distributed on the coiling roller, each spiral rack plate is respectively provided with positive spiral racks and reverse spiral racks, in the use process, the spiral rack plates can bring fed threshing blanks into a machine body, because the positive and reverse spiral racks are arranged on the spiral rack plates, the brought threshing blanks can be uniformly distributed in the straight operation conveying process, the machine clamping phenomenon caused by the deviation towards the two sides cannot be caused, the structure is simple, and the normal faultless operation of the threshing machine can be favorably realized.

Description

technical field [0001] The invention relates to a threshing machine, in particular to a threshing machine equipped with positive and negative spiral rack rolls. Background technique [0002] The universal threshing machine used for threshing corn, rice and wheat is equipped with a roll for feeding in the feed port of the machine body. The common roll is generally a helical rack with a one-way helical rack. When the thresher is running, because the spiral rack is in a one-way spiral state, the rolled billets will gradually accumulate on both sides, which will cause the winding roller and other parts to be stuck, resulting in abnormal operation and failure of the thresher. Frequent, directly affects the threshing efficiency. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned existing truck phenomenon, and provide a thresher equipped with positive and negative spiral rack rolls, which can allow the fed blanks to run smooth...
