Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and in particular to a grain selection device for grain entering a grain warehouse. Background Technology

[0002] Grain silos are specialized buildings used for large-scale grain storage, requiring properties such as moisture resistance, heat insulation, and ventilation. They can be categorized by form into room-type silos and silos, and by function into bulk silos and packaged silos. When transporting grain to a grain silo for storage, it is necessary to separate and remove any straw and impurities mixed in with the grain.

[0003] Currently, grain is mostly transported into the granary by conveyor belts. Because the conveyor belts transport a large amount of grain, blowers can only remove impurities from the surface of the grain, but cannot remove impurities from the bottom layer of grain, resulting in a low cleaning effect on the grain. Utility Model Content

[0004] In order to solve the problems of the prior art, this utility model provides a grain sorting device for grain entering a grain warehouse.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A grain sorting device for grain entering a grain warehouse includes a screening box. A reciprocating trough extending into the interior is provided on one side of the screening box near the top edge. A screen plate is slidably arranged between the inner walls on both sides of the reciprocating trough. A bellows is fixed in the middle of one side of the screening box. One end of the bellows extends obliquely into the interior of the screening box. A through-hole extending into the other side is provided on one side of the screening box near the bottom edge. Side plates are fixed at both ends of the through-hole at the two sides of the edge.

[0006] Optionally, two side plates located on one side of the screening box are grouped together, and V-shaped conveyor rollers are rotatably installed between the opposite sides of the two side plates in each group.

[0007] Optionally, a conveyor belt is provided between the outer surfaces of the two V-shaped conveyor rollers, and a guide pipe is connected to the top of the screening box near the other edge.

[0008] Optionally, a feed trough is provided on the top of the screen plate. The bottom surface of the feed trough is inclined and extends to one side of the screen plate. Multiple screening ports that extend to the bottom are provided at equal intervals on the bottom surface of the feed trough.

[0009] Optionally, a fan blade roller is rotatably mounted between the inner walls of both sides of the wind box near one edge, and a driven pulley is rotatably mounted on the front side of the wind box, with the driven pulley and one end of the fan blade roller being fixed to each other.

[0010] Optionally, a lever is fixed to the front side of the sieve plate, and a waist-shaped opening extending to the rear side is provided on the front side of the lever. A lever is fixed near the edge of the front side of the driven pulley, and the lever is slidably disposed inside the waist-shaped opening.

[0011] Optionally, a mounting base is fixed to the front side of the screening box, a motor is fixed on the mounting base, a drive pulley is fixed to the output end of the motor, and a belt is provided between the drive pulley and the driven pulley.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art. Of course, any product implementing this utility model does not necessarily need to achieve all of the following advantages at the same time: 1. In this utility model, the grain transported to the granary is first transported to a sieve plate for screening. During the screening process, the grain flows along the inclined surface at the bottom of the feed trough to the screening port. Then, the airflow blown by the bellows is directed towards the screening port, so that impurities in the grain can be blown upward through the screening port. The blown impurities are discharged through the guide pipe. At the same time, when the sieve plate is screening, the driven pulley drives the lever to move the lever back and forth, which can make the sieve plate reciprocate to improve the efficiency of dispersing the grain during screening and improve the screening effect. The screened grain falls from one end of the sieve plate onto the conveyor belt inside the screening box and is transported out by the conveyor belt.

[0013] 2. In this utility model, when the equipment is working, the motor drives the drive pulley to rotate. When the drive pulley rotates, it drives one of the V-shaped conveyor rollers to rotate, thereby driving the conveyor belt to convey. At the same time, the drive pulley drives the driven pulley to rotate synchronously through the belt. When the driven pulley rotates, it drives the fan roller to rotate. The fan blades on the fan roller can transport airflow from the outside to the inside of the air box, so that the airflow blows out from one end of the air box. On the other hand, when the driven pulley rotates, it can drive the lever to reciprocate the lever plate, causing the screen plate to reciprocate. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Example 1, such as Figure 1-4 As shown, this utility model provides a technical solution for a grain sorting device for grain storage: it includes a screening box 1, a reciprocating groove 2 extending into the interior of the screening box 1 near the top edge on one side, a screen plate 3 slidably disposed between the inner walls of the two sides of the reciprocating groove 2, a bellows 4 fixed in the middle of one side of the screening box 1, one end of the bellows 4 extending obliquely into the interior of the screening box 1, and a through-hole 12 extending into the other side near the bottom edge on one side of the screening box 1, with side plates 5 fixed at both ends of the through-hole 12 at the two side edges.

[0019] The effect achieved by the entire embodiment 1 is that the grain transported to the grain warehouse is first transported to the screen plate 3 for screening. During the screening process, the grain flows along the inclined surface at the bottom of the feed trough 16 to the screening port 17. Then, the airflow blown by the bellows 4 blows the airflow towards the screening port 17, thereby blowing the impurities in the grain upward through the screening port 17. The blown impurities are discharged through the guide pipe 6. At the same time, when the screen plate 3 is screening, the driven pulley 18 drives the lever 19 to move the lever 10 back and forth, thereby making the screen plate 3 reciprocate to improve the efficiency of dispersing the grain during screening and improve the screening effect. The screened grain falls from one end of the screen plate 3 onto the conveyor belt 14 inside the screening box 1 and is transported out by the conveyor belt 14.

[0020] Example 2, as Figure 1-4As shown, two side plates 5 located on one side of the screening box 1 form a group. V-shaped conveyor rollers 13 are rotatably arranged between opposite sides of the two side plates 5 in each group. A conveyor belt 14 is arranged between the outer surfaces of the two V-shaped conveyor rollers 13. A guide pipe 6 is connected to the top of the screening box 1 near the other edge. A feed chute 16 is opened on the top of the screen plate 3. The inner bottom surface of the feed chute 16 is inclined and extends to one side of the screen plate 3. Multiple screening ports 17 that penetrate to the bottom are equidistantly opened on the inner bottom surface of the feed chute 16. Rotatably arranged between the inner walls of the two sides of the air box 4 near one edge. There is a fan roller 15, and a driven pulley 18 is rotatably mounted on the front side of the air box 4. The driven pulley 18 is fixed to one end of the fan roller 15. A baffle plate 10 is fixed on the front side of the screen plate 3. A waist-shaped opening 11 extending to the rear side is opened on the front side of the baffle plate 10. A lever 19 is fixed near the edge on the front side of the driven pulley 18. The lever 19 is slidably mounted inside the waist-shaped opening 11. A mounting base 7 is fixed on the front side of the screening box 1. A motor 8 is fixed on the mounting base 7. A drive pulley 9 is fixed at the output end of the motor 8. A belt 20 is provided between the drive pulley 9 and the driven pulley 18.

[0021] The effect achieved by the entire embodiment 2 is that when the equipment is working, the motor 8 drives the drive pulley 9 to rotate. When the drive pulley 9 rotates, it drives one of the V-shaped conveyor rollers 13 to rotate, thereby driving the conveyor belt 14 to convey. At the same time, the drive pulley 9 drives the driven pulley 18 to rotate synchronously through the belt 20. When the driven pulley 18 rotates, it drives the fan roller 15 to rotate. The fan blades on the fan roller 15 can transport the airflow from the outside to the inside of the air box 4, so that the airflow blows out from one end of the air box 4. On the other hand, when the driven pulley 18 rotates, it can drive the lever 19 to reciprocate the lever plate 10, thereby driving the screen plate 3 to reciprocate.

[0022] Working principle: Grain transported to the grain silo is first fed to screen plate 3 for screening. During the screening process, the grain flows along the inclined surface at the bottom of the feed trough 16 to the screening port 17. Then, the airflow blown by the bellows 4 is directed towards the screening port 17, which blows impurities in the grain upwards through the screening port 17. The blown impurities are discharged through the guide pipe 6. At the same time, when the screen plate 3 is screening, the driven pulley 18 drives the lever 19 to move the lever 10 back and forth, which in turn makes the screen plate 3 reciprocate, improving the efficiency of grain dispersion during screening and improving the screening effect. The screened grain falls from one end of the screen plate 3 onto the conveyor belt inside the screening box 1. On 14, the conveyor belt 14 transports the contents out. When the equipment is working, the motor 8 drives the drive pulley 9 to rotate. When the drive pulley 9 rotates, it drives one of the V-shaped conveyor rollers 13 to rotate, thereby driving the conveyor belt 14 to convey the contents. At the same time, the drive pulley 9 drives the driven pulley 18 to rotate synchronously through the belt 20. When the driven pulley 18 rotates, it drives the fan roller 15 to rotate. The fan blades on the fan roller 15 can transport the airflow from the outside to the inside of the air box 4, so that the airflow blows out from one end of the air box 4. On the other hand, when the driven pulley 18 rotates, it can drive the lever 19 to reciprocate the lever plate 10, thereby driving the screen plate 3 to reciprocate.
