[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] For examples, see Figure 1 and Figure 2The present application provides a grain silo transfer device with dust removal function, comprising a support body 1, wherein the support body can be a structure such as a bracket or a support column, a screen 2 is installed on the support body, the screen is inclined, and a guide plate 3 is connected to one end with a relatively small height, the top of the guide plate is connected to the screen, and the bottom is arc-shaped, and the bottom of the guide plate is provided with a drainage structure for guiding grain into the granary on the side away from the screen; a wind dust removal structure is installed on the guide plate;

[0023] In this embodiment, the wind dust removal structure includes a dust removal box 4, the bottom surface of the dust removal box is arc-shaped, and there is a distance between the dust removal box and the guide plate for grain to pass through. When making it, supports can be set on both sides of the guide plate, such as setting two support plates on both sides of the bottom end of the dust removal box, and the support plates are connected to the guide plate; an air inlet 4-1 is set on the side of the dust removal box facing away from the screen, and an air outlet is set on the side of the dust removal box facing the screen, and an induced draft fan 5 is set in the air outlet, and a filter screen 6 is installed on the inner wall of the dust removal box at a position corresponding to the air outlet, wherein the air inlet and the induced draft fan can be set at one or more, and when multiple induced draft fans are set, one or more filter screens can be set, and no specific limitation is made here;

[0024] In this embodiment, the drainage structure includes a bottom plate 14 and a support plate 15, a partition 16 is arranged between the bottom plate and the support plate, the partition divides the space between the bottom plate and the support plate into a first chamber 17 and a second chamber 18, the first chamber is farther away from the support body relative to the second chamber; a grain outlet 19 is arranged at one end of the first chamber away from the partition; a top plate 20 is arranged above the support plate at a position corresponding to the first chamber, a sealing plate 21 is arranged between the top plate and the support plate, the sealing plate is located at one end of the top plate close to the support body, so that a third chamber 22 is formed between the top plate and the support plate, and the third chamber is connected to the inside of the dust removal box; a grain inlet 23 is arranged on the support plate, and the grain inlet is located on the side of the sealing plate close to the support body.

[0025] When the above-mentioned grain silo transfer device with dust removal function is used, refer to Figure 1The grain outlet is set at 29-1, corresponding to the inlet of the granary. When the grain is transferred, it is introduced into the screen from a high place, and then the grain moves downward along the screen. During the movement of the grain on the screen, part of the dust in the grain is first screened out through the screen, forming a dust removal; then the grain reaches the guide plate, falls along the inclined part, and finally flows out through the arc-shaped bottom. Since the grain converts potential energy into kinetic energy when flowing out, it is lifted up when flowing out. At this time, the airflow formed by the operation of the induced draft fan attracts the dust in the raised grain, and the dust enters the dust removal box through the air inlet and is filtered The net is intercepted in the dust removal box, thus forming a secondary dust removal; the grain after the secondary dust removal falls onto the support plate, enters the first chamber through the grain inlet, moves downward along the first chamber, and is finally discharged through the grain outlet, and enters the granary along the inlet of the granary 29. In this process, due to the third chamber and the dust removal box, the induced draft fan has a negative pressure drainage effect on the third chamber, so that the third chamber attracts the dust in the grain discharged from the grain outlet, thus forming a tertiary dust removal; in this way, the grain undergoes three dust removals during transportation, the operation is relatively simple, and the work efficiency is high. The granary transportation device with dust removal function in this embodiment can be used for transportation and dust removal of grains such as soybeans, mung beans, red beans, and sorghum.

[0026] In the above embodiment, the bottom plate and the support plate are preferably arranged at an angle, and the inclination direction is the same as the inclination direction of the filter screen; first baffles 24 are arranged on both sides of the bottom plate, the support plate and the top plate, as well as on both sides of the guide plate. Generally, one first baffle is arranged on each side, and the two first baffles are respectively connected to the bottom plate, the support plate and the top plate to limit the diffusion of grain to both sides; a second baffle 25 is arranged on the top plate, and the height of the second baffle is greater than or equal to the height of the dust removal box. The first baffle extends to both sides of the second baffle. The second baffle is preferably arranged at an angle, and the bottom end is close to the dust removal box relative to the top end, so that the second baffle prevents the grain from being lifted up and flying forward too far, which is not conducive to the grain entering the grain inlet.

[0027] As a preferred embodiment, an arc-shaped extension 20-1 is provided at one end of the top plate away from the support body, and third baffles 26 are provided on both sides of the arc-shaped extension, so that the mutually extending parts and the third baffles form a cover body to cover the grain outlet, and when the grain falls through the grain outlet, it is easier to form an upward airflow to remove dust from the grain under the action of the induced draft fan. For the stability of the device, a support column 27 for supporting the bottom plate is preferably fixed below the bottom plate.

[0028] As a preferred implementation, see Figure 2, a dust outlet is provided at the bottom end of the dust removal box, and a plug 7 is installed inside the bottom end of the dust removal box, a first electromagnet 8 is fixed on the plug, a support body 9 is provided in the dust removal box, wherein the support body can be a bracket or a support plate or support rod fixed transversely in the box, and a second electromagnet 10 is provided on the bottom surface of the support body corresponding to the position of the first electromagnet; a dust receiving plate 11 is slidably connected to the top surface of the support body, and the dust receiving plate is located below the filter screen, and the thickness of the dust receiving plate gradually increases from the side close to the induced draft fan to the other side, and a third electromagnet 12 is installed on the side of the dust receiving plate away from the induced draft fan, and a fourth electromagnet 13 is installed on the inner wall of the dust removal box corresponding to the position of the third electromagnet. In this embodiment, the first electromagnet, the second electromagnet, the third electromagnet and the fourth electromagnet preferably use DC electromagnets, so that the direction of the magnetic poles of the electromagnets can be changed by reversely supplying power to the electromagnets, thereby controlling the two electromagnets to switch between attraction and repulsion; when this structure is used, there are at least two ways of use:

[0029] Usage 1: In the original state, the first electromagnet and the second electromagnet are controlled to repel each other, and the third electromagnet and the fourth electromagnet are controlled to repel each other. The dust attracted by the induced draft fan during operation is blocked by the filter into the dust removal box, and the accumulated dust falls to the dust receiving plate under the action of gravity. When the transfer is completed, the induced draft fan is stopped, and the first electromagnet and the second electromagnet are controlled to attract each other. The dust receiving plate moves to the left and sticks to the inner wall of the left side of the dust removal box. The dust falls along the inclined surface of the dust receiving plate through the right side of the dust receiving plate. At the same time, the third electromagnet and the fourth electromagnet are controlled to attract each other, the plug moves up, the dust outlet is opened, and the dust falls through the dust outlet and is finally cleaned up by the staff. This usage method is suitable for dust removal of grains with large particle weight such as corn;

[0030] Usage 1: In the original state, the first electromagnet and the second electromagnet are controlled to repel each other, and the third electromagnet and the fourth electromagnet are controlled to repel each other. The dust attracted by the induced draft fan during operation is blocked by the filter into the dust removal box, and the accumulated dust falls to the ash receiving plate under the action of gravity. When the transfer is completed, the induced draft fan is stopped, and the first electromagnet and the second electromagnet are controlled to attract each other. The ash receiving plate moves to the left and sticks to the inner wall of the left side of the dust removal box. The dust falls along the inclined surface of the ash receiving plate through the right side of the ash receiving plate. At the same time, the third electromagnet and the fourth electromagnet are controlled to attract each other, the plug moves up, the dust outlet is opened, and the dust falls through the dust outlet and is finally cleaned up by the staff. This usage method is suitable for dust removal of grains with large particle density;

[0031] Usage 2: In the original state, the first electromagnet and the second electromagnet are controlled to repel each other, and the third electromagnet and the fourth electromagnet are controlled to attract each other. During the operation of the induced draft fan, the dust attracted outside the dust outlet is blocked by the filter and moved into the dust removal box. The accumulated dust falls onto the dust receiving plate under the action of gravity. At the same time, during the operation of the induced draft fan, negative pressure attraction is formed at the dust outlet. The attracted dust moves upward through the left side of the dust receiving plate and is blocked by the filter and moved into the dust removal box. In this way, the grain flowing under the dust removal box is dusted, which increases the number of dust removal times. At the same time, The opening of the dust outlet increases the air inlet, thereby weakening the wind force at the air inlet on the left side of the dust box, preventing the air inlet on the left side of the dust box from having too much suction force and attracting grains to fall close to the dust box, affecting the subsequent lifting of grains; when the transfer is completed, the induced draft fan is stopped, the first electromagnet and the second electromagnet are controlled to attract each other, the ash receiving plate moves to the left and sticks to the inner wall of the left side of the dust box, the dust falls along the inclined surface of the ash receiving plate through the right side of the ash receiving plate, the dust falls through the dust outlet and is finally cleaned up by the staff. This usage method is suitable for dust removal of grains with lower particle density.

[0032] As an implementation method, see Figure 3 A rotating shaft 30 and a motor for driving the rotating shaft to rotate are installed on at least one of the first baffles, which is located on the side of the dust removal box away from the screen. When manufacturing, the distance between the rotating shaft and the guide plate is preferably the same as the distance between the dust removal box and the guide plate. A material stripping plate 31 is installed on the rotating shaft, and the rotating shaft is arranged near the end of the guide plate away from the screen. When the grain particles leave the bottom of the guide plate, this structure drives the material stripping plate to strip the grain particles through the rotation of the rotating shaft, so that the kinetic energy of the grain particles increases when they leave the guide plate, which is conducive to the grain particles being lifted upward.

[0033] In order to prevent grain particles falling on the screen from escaping from the screen to the sides or upward, fourth baffles 32 are provided on both sides of the screen, and the end of the screen with a relatively large height is bent upward.

[0034] In the above embodiment, the screen can be directly fixed on the support body and directly connected to the guide plate. At this time, the top to bottom of the guide plate can be directly set to be inclined, and the inclination direction can be the same as the inclination direction of the screen. The inclination angle is preferably greater than the inclination angle of the screen, and the top is directly connected to the bottom end of the screen; in order to improve the efficiency of the screen, the applicant has also made the following design: the above-mentioned support body is a support frame, the screen is slidably connected to the support frame, and a reciprocating motion device 28 for driving the screen to move back and forth is installed on the support frame. The reciprocating motion device can use an existing device as long as it can drive the screen to reciprocate. At this time, the top of the guide plate can be set to be bent and overlapped with the guide plate, and the top to the bottom is set to be inclined.
