Description

Roller and screen box for specific gravity compound cleaning and sorting machine and double specific gravity compound cleaning and sorting machine

Technical Field

The utility model belongs to the technical field of the relevant technique of agricultural machine equipment and specifically relates to a cylinder, sieve case and two proportion double entry cleaning mills that are used for proportion double entry cleaning mill.

Background

The screen box part of the present specific gravity compound cleaning and sorting machine is divided into a brush type and an elastic ball type. For crops with regular shapes, such as beans, corns, wheat and the like, an elastic ball type sieve box is used; for crops with irregular shapes such as peanut fruits, camellia seeds and the like, a brush type sieve box is used.

There are several problems and disadvantages with existing brush type screen boxes. Particularly, due to different maturity degrees of crops such as peanuts and the like, the situation of big end and small end of the fruit shape is easy to occur; the small end of the fruit is inserted into the sieve pores of the sieve sheet and the big end of the fruit cannot fall down, the fruit is inserted more and more tightly under the influence of the vibration force of the machine, finally, the crop is clamped on the sieve pores and cannot fall down, and the sieve pores are completely blocked when the fruit is serious, so that the screening function of the machine is lost. The brush type screen box is characterized in that a brush frame body which moves in a reciprocating mode is arranged below a screen sheet, and the screen sheet is brushed in a reciprocating mode through bristles to play a role in cleaning the screen. The defects of the method are proved to be as follows through years of market practice;

1. the brush hair of the brush is generally made of nylon or PVC materials, and the brush hair has the defects of being softer and not cleaning peanuts blocked in the sieve pores without enough force. And the anti-aging capability and the anti-abrasion capability are poor, and the user needs to adjust or replace the brush regularly, so that the production cost is increased, and time and labor are wasted.

2. The brush transmission mechanism adopts lever support arm transmission, the structure is more complex, and the production process requirement is higher.

3. The brush transmission mechanism and the screen box transmission mechanism share one motor to output power, and once the brush transmission mechanism breaks down, the transmission of the screen box and even the whole machine are affected, so that the number of machine fault points is increased, and the stability is poor.
