Straw separating device

Abstract

The invention relates to an agricultural material screening tool, and in particular relates to a straw separating device which comprises a frame, a screen drum arranged above the frame and a storage battery, a main shaft is arranged in the center of the screen drum, a front supporting beam and a rear supporting beam are arranged at the positions, located at the two ends of the screen drum, of the upper portion of the frame respectively, the two sides of the main shaft body are connected with the front supporting beam and the rear supporting beam through bearings respectively, one end of the main shaft is fixedly connected with the end of the connecting rod, the other end of the connecting rod is connected with the handle, the end, away from the connecting rod, of the main shaft is connected with an output end shaft of the driving motor, the driving motor is connected with the storage battery through a wire, the main shaft is fixedly connected with the inner wall of the screen drum through the connecting rod, a sleeve is arranged on one side of the frame, and a connecting elbow matching and connected with the sleeve in an inserted mode is fixedly arranged on the side wall of the storage battery.

Description

technical field [0001] The invention relates to an agricultural material screening tool, in particular to a straw separating device. Background technique [0002] In agricultural labor, we often use sieves to separate the particle size of rice and wheat. At present, the sieves we commonly use are mainly reciprocating sieves. By alternately exerting force on both sides of the sieve, the particles are separated by gravity and material inertia. Conventional reciprocating sieves There are the following problems: (1) the amount of material input is small each time. Since there is only one contact surface between the screen and the material, the amount of material should not be too much each time, otherwise the coarse material below will block the fine material from going down, and the material screening will not be complete; Hold the sieve reciprocatingly, and at the same time need to bear the weight of the material; (3) The utilization efficiency of the sieve is low. The conta...

AI Technical Summary

Problems solved by technology

Since there is only one contact surface between the screen and the material, the amount of material should not be too much each time, otherwise the coarse material below will block the fine material from going down, and the material screening will not be complete; Hold the sieve reciprocatingly, and at the same time need to bear the weight of the material; (3) The utilization efficiency of the sieve is low

The contact surface between the sieve and the material is limited, the coarse material blocks the sieve hole, and the fine material should not be sieved out

When the material contains grain husk, the above problems will become more obvious, and the sieve hole will be blocked seriously, and the sieving operation will be difficult.
