Abstract

The utility model discloses a grain cleaning windmill which comprises a hopper, a separation cavity and a wind cavity; the tangential line at the connection part of the inner wall at a wind outlet of the wind cavity and the inner wall of a baseplate of the separation cavity faces to a feeding port of the hopper; and a top plate of the separation cavity is higher than the feeding port of the hopper. The tangential line at the connection part of the inner wall at a wind outlet of the wind cavity and the inner wall of a baseplate of the separation cavity faces to the feeding port of the hopper, wind generated in operation of a blower device completely and slantingly is blown toward the discharge opening; and remaining sundries in grains in the separation cavity are completely suspended at the upper part of the separation cavity, so that the separation is more thorough. The windmill has the advantages of good separation effect, high operating efficiency, simple structure, light weight and low cost.

Description

The grain cleaning windmill

Technical field

The utility model relates to a kind of grain cleaning machine, particularly a kind of grain cleaning windmill.

Background technology

The grain cleaning windmill that uses at present, the hopper discharging opening is far away from the wind chamber, and the air-out direction in wind chamber is near the wind chamber; The wind that the air-blast device running produces, some wind circulates in the wind chamber, and wind-force is not enough; Foreign material can not be separated up hill and dale in the cereal, and separating effect is undesirable, inefficiency.

The utility model content

The technical problem that the utility model solved is to provide the grain cleaning windmill of a kind of good separating effect, high efficiency.

In order to solve the problems of the technologies described above, the grain cleaning windmill of the utility model comprises hopper, disengagement chamber and wind chamber, and the tangential direction of said wind chamber air outlet place inwall and said disengagement chamber plate inner wall junction is pointed to the feed opening of said hopper.

As further improvement, the top board of said disengagement chamber is higher than the hopper feed opening.

Adopt the structure of the utility model; Because the tangential direction of wind chamber air outlet place inwall and said disengagement chamber plate inner wall junction is pointed to the feed opening of said hopper; The wind that the air-blast device running produces is the oblique feed opening that blows to all; Flow down foreign material in the cereal of the disengagement chamber disengagement chamber top that suspended fully and be discharged from, fall into discharging opening naturally from great cereal.Because the top board of disengagement chamber is higher than the hopper feed opening, flow down foreign material in the cereal of disengagement chamber by the disengagement chamber top that suspends fully, separate more thorough.The utility model good separating effect, high efficiency, and simple in structure, light, cost is low.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in detail:

As shown in Figure 1, the grain cleaning windmill of the utility model comprises hopper 1, disengagement chamber 5, wind chamber 2, and the tangential direction of said wind chamber 2 air outlet place inwalls 3 and said disengagement chamber 5 plate inner wall junctions is pointed to the feed opening of said hopper 1.

In order to increase the space of disengagement chamber, strengthen separating effect, the top board of said disengagement chamber 5 is higher than hopper 1 feed opening.

In order to prevent the cereal hopper that is blown out, said hopper 1 feed opening leans on 2 sidewall bottoms, wind chamber to extend beyond opposing sidewalls bottom horizontal line downwards.

In order to prevent to produce return air,, hopper 1 feed opening also is provided with return air baffle plate 4 below leaning on wind chamber 2 sidewalls; Said wind chamber 2 air outlet place inwalls 3 lean on 2 sidewall bottoms, wind chamber with the feed opening that the tangential direction of said disengagement chamber 5 plate inner wall junctions is pointed to said hopper 1.
