Abstract

The utility model relates to an improved foot tread thresher which comprises a threshing roller, a main shaft, supporting frames, a foot tread mechanism, big and small sprocket wheels, and chains. The utility model is characterized in that bearing covers are respectively fixed on both ends of a roller, wherein, the small sprocket wheels are fixed on the end surface of one of the bearing covers; the main shaft supports the roller through bearings which are installed inside the bearing covers; both ends of the main shaft are fixed on the supporting frames respectively. The utility model has the advantages of compact structure, low cost, and portable use.

Description

Pedal thresher

The utility model relates to agricultural mechanical field, particularly a kind of improvement of pedal thresher.

Disclosed foot pedal threshing machine in CN2053844; its structure comprises threshing cylinder, main shaft, support, footstep mechanism, large and small sprocket wheel and chain etc.; join with shaft joint between minor sprocket and the threshing cylinder; the other end of threshing cylinder also is connected to shaft joint; during use, power passes to main shaft by footstep mechanism through large and small sprocket wheel, makes threshing cylinder follow its rotation; this machine spindle and threshing cylinder are to be fixed together, and rotation friction is bigger.

The purpose of this utility model is that a kind of main shaft of design is motionless, is directly driven the thresher of threshing cylinder by minor sprocket.

Task of the present utility model is to realize like this, be fixed with bearing cap respectively at the threshing cylinder two ends, on the bearing cap end face that minor sprocket is fixed therein, main shaft is supporting threshing cylinder by the bearing that is located in the bearing cap, and the main shaft two ends are separately fixed on the support.This equipment is not followed rotation because of main shaft in use, has reduced frictional force, and it is more light that pin is stepped on.

The utlity model has compact conformation, cost is low, uses light characteristics.

Accompanying drawing, the pedal thresher schematic diagram.

With reference to accompanying drawing, be fixed with bearing cap 2 respectively at the two ends of threshing cylinder 1, on the end face of the bearing cap 2 that minor sprocket 3 is fixed therein, main shaft 4 is supporting cylinder 1 by the bearing 5 that is located in the bearing cap 2, and main shaft 4 two ends are separately fixed on the support 6.As long as adjust the hold-down nut 7 at main shaft 4 two ends, can change the contraposition relation of large and small sprocket wheel.

Claims

1, a kind of pedal thresher of forming by threshing cylinder, main shaft, support, footstep mechanism, hinge wheel, minor sprocket and chain; it is characterized in that threshing cylinder two is fixed with bearing cap respectively; on the bearing cap end face that minor sprocket is fixed therein; main shaft is supporting threshing cylinder by the bearing that is located in the bearing cap, and the main shaft two ends are separately fixed on the support.
