Description

Grain clearance sieve dust collector for feeding

Technical Field

The utility model relates to a grain cleaning equipment, in particular to grain clearance sieve dust collector for feeding.

Background

After being harvested, grains are usually dried and cleaned and then sent to a granary for storage, and the existing grain cleaning method is to send the grains to a vibrating screen and remove dust in the grains through the vibrating action of the vibrating screen.

However, the processing has a defect that the grains are gathered together in the vibrating screen, so that dust attached to the surfaces of the grains cannot be removed, a lot of dust still adheres to the surfaces of the grains sent out from the discharging end of the vibrating screen, and the cleaning is not thorough.

In order to solve the problems, the conventional method is to firstly remove dust from grains by using a dust removal device before the grains enter a vibrating screen, but when the conventional dust removal device works, the movement track of the grains in the dust removal device is fixed, and the grains and dust are separated in the movement by setting a complex movement track, so that the dust can be sucked away by dust collection equipment, and the purpose of removing dust is achieved.

However, the movement track of the grain in the existing dust removal device is fixed and cannot be adjusted, when the grain processing capacity is increased, the separation effect of the grain and the dust is not ideal enough, and when the grain processing capacity is reduced, the processing efficiency cannot be guaranteed.

SUMMERY OF THE UTILITY MODEL

To the dust collector that grain clearance sieve that prior art exists was used can not be according to the nimble problem of adjusting grain movement track of the change of grain handling capacity, the utility model aims to provide a dust collector for grain clearance sieve feeding.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a dust removal device for feeding of a grain cleaning sieve comprises a support connected with the grain cleaning sieve and a sieve cylinder arranged on the support, wherein the top of the sieve cylinder is provided with a feeding hole, and the bottom of the sieve cylinder is provided with a discharging hole; discharge plates which are arranged in a staggered mode are arranged on two opposite side walls of the screen drum; the discharging plate is fixed on a rotating shaft, the rotating shaft is rotatably connected to the side wall of the screen drum, an action drum is coaxially and fixedly installed on the rotating shaft, an opening for exposing the action drum is formed in the side wall of the screen drum, and a handle fixedly connected with the action drum is arranged outside the screen drum; the action cylinder is provided with a locking mechanism, the locking mechanism comprises a fixed seat, a guide rod, a compression spring and a locking seat, the fixed seat is fixed on the outer wall of the screen cylinder, the guide rod is fixed on the fixed seat, the locking seat is sleeved on the guide rod, and the compression spring is sleeved on the guide rod between the fixed seat and the locking seat; the outer wall of the action cylinder is provided with clamping teeth which are uniformly distributed in the circumferential direction, and the side wall of the locking seat facing the opening is provided with tooth grooves matched with the clamping teeth.

As a further limitation of the present invention, the rotating shaft is rotatably connected to two opposite side walls of the opening, and the actuating cylinder is in clearance fit with the opening.

As a right step, the locking seat is connected with a toggle handle.

As a further limitation to the present invention, the latch has an involute tooth profile.

As a further limitation to the present invention, a circle of sealing member is disposed on the side wall of the opening.

As a further limitation to the present invention, the sealing member is a sponge or wool felt.

By adopting the technical scheme, due to the arrangement of the rotating shaft, the action barrel, the opening, the handle and the locking mechanism, the action barrel and the rotating shaft can be driven to rotate by operating the handle, and the discharging plate is driven to rotate by the rotating shaft, so that the angle of the discharging plate is adjusted, and the movement track of grains after falling on the discharging plate is correspondingly changed; the smaller the included angle between the discharging plate and the horizontal plane is, the lower the grain discharging speed is, the longer the movement time of grains on the discharging plate is, the easier the dust is separated from the grains, but the grain processing capacity is reduced; on the contrary, when the included angle between the discharging plate and the horizontal plane is increased, the discharging speed of the grains is increased, the grain processing capacity is increased, but the movement time of the grains on the discharging plate is reduced, and the dust is not easily separated from the grains; and because the arrangement of the compression spring, the guide rod, the locking seat and the tooth grooves on the locking seat in the locking mechanism, the rotating position of the action cylinder can be flexibly adjusted by operating the separation and separation of the locking seat and the action cylinder, and the purpose of adjusting the angle of the stripper plate is achieved conveniently and quickly.
