Description

Technical Field

[0001] This utility model relates to the field of soybean seed screening technology, specifically a soybean seed gravity cleaning machine. Background Technology

[0002] A gravity separator is a device that uses the difference in specific gravity of materials for cleaning or grading. It is mainly used to remove impurities such as husks, stones, shriveled seeds, insect-infested seeds, and moldy seeds from materials. Its working principle is that the reciprocating vibration of the screen bed and the airflow of the fan cause the heavier seeds to fall to the lower layer and move upward, while the lighter seeds float to the upper layer and drift downward, thereby achieving the purpose of cleaning or grading.

[0003] Existing soybean seed gravity sorting equipment causes soybean seeds to collide with each other under vibration during the specific gravity screening process, which causes dust on the surface of the soybean seeds to fall off. This results in a large amount of dust being collected during the specific gravity screening process, affecting air quality. To solve the above problems, this application proposes a soybean seed gravity cleaning machine. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] To address the technical problems existing in the background art, this utility model proposes a soybean seed gravity cleaning machine. An air intake fan injects outside air into the lower air guide hood, increasing the air pressure inside the lower air guide hood. This causes the air to move upward through the dust removal mesh. As the soybean seeds move forward, they collide with each other, causing the dust adhering to their surfaces to fall off. The fallen dust rises under the blowing of the upward airflow. At the same time, a dust suction pump, in conjunction with the upper dust collection hood, can suck up the rising dust and discharge it into a dust storage box for storage. This reduces dust generation during gravity cleaning, thus solving the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To solve the above technical problems, this utility model provides a soybean seed gravity cleaning machine, including a gravity meter and a flow guide baffle. The flow guide baffle is located at the outlet of the gravity meter and is arranged symmetrically. A dust removal screen is provided in the middle of the inner cavity of the feed trough of the gravity meter.

[0008] The lower surface of the feed trough of the gravity meter is provided with a lower air guide hood corresponding to the position of the dust removal screen plate. A slag storage pipe is connected to the center of the lower air guide hood. Air inlets are opened through the two sides of the lower air guide hood, and air intake fans are installed on the surface of the air inlets.

[0009] The gravity meter is equipped with an upper dust collection hood, and the top of the upper dust collection hood is connected to a dust storage box through an air guide pipe. A dust suction pump is installed on the surface of the dust storage box.

[0010] Preferably, the slag storage pipe is used to store debris leaking from the dust removal screen, and a bottom cover is threadedly connected to the bottom of the slag storage pipe.

[0011] Preferably, the feed chute of the gravity meter has support frames welded to both sides, the support frames are symmetrically arranged, and the upper dust collection hood is welded to the top of the support frames.

[0012] Preferably, a folded rubber belt is movably provided between the top of the feed chute of the gravity meter and the upper dust collection hood. The folded rubber belt is symmetrically arranged, and when unfolded, it is used to seal the area between the top of the feed chute of the gravity meter and the upper dust collection hood.

[0013] Preferably, the top of the feed chute of the gravity meter is provided with a lower guide groove, the lower surface of the upper dust collection hood is provided with an upper guide groove, and the top and bottom of the folded rubber belt are respectively inserted into the lower guide groove and the upper guide groove.

[0014] Preferably, a fixed bracket is welded to one end of the feed chute of the gravity meter, and one end of the folded rubber belt is fixedly connected to the fixed bracket.

[0015] Preferably, the other end of the folded rubber strip is connected to a guide seat, and the bottom of the guide seat is slidably connected to the lower guide groove.

[0016] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0017] 1. In this utility model, the air intake fan injects outside air into the lower air guide hood, increasing the air pressure inside the lower air guide hood. This causes the air to move upward through the dust removal mesh plate. As the soybean seeds move forward, they collide with each other, causing the dust adhering to their surfaces to fall off. The fallen dust rises under the blowing of the rising airflow. At the same time, the dust suction pump, in conjunction with the upper dust collection hood, can suck up the rising dust and discharge it into the dust storage box for storage. This reduces the generation of dust during gravity separation.

[0030] It should be noted that the gravity separator 1 performs gravity separation on soybean seeds. The soybean seeds move in the feed chute under the action of vibration. During the movement, the air intake fan 7 injects outside air into the lower air guide hood 4, and the air pressure in the lower air guide hood 4 increases, causing the air to move upward through the dust removal screen 3. As the soybean seeds move forward, they collide with each other, causing the dust adhering to the surface to fall off. The fallen dust rises under the blowing of the rising airflow. At the same time, the dust suction pump 11, in conjunction with the upper dust collection hood 9, can suck up the rising dust and discharge it to the dust storage box 10 for storage. This can reduce the generation of dust during gravity separation.

[0031] In this embodiment, as Figure 5 As shown, the slag storage pipe 5 is used to store the debris leaking out of the dust removal screen plate 3, and the bottom of the slag storage pipe 5 is threadedly connected to a lower cover 6.

[0036] It should be noted that the upper dust collection hood 9 and the material guide chute are sealed by a folded rubber strip 14. One end of the folded rubber strip 14 is fixed to the fixed bracket 13, and the other end is fixed to the guide seat 15. The top and bottom of the folded rubber strip 14 are respectively inserted into the upper guide groove 16 and the lower guide groove 12. The guide seat 15 moves within the lower guide groove 12, which can fold the folded rubber strip 14, thereby exposing the material guide chute for easy observation during the cleaning process and making it more convenient to use.

[0037] The working principle and usage process of this utility model: The gravity separator 1 performs gravity separation on the soybean seeds. The soybean seeds move within the feed chute under vibration. During this movement, the air intake fan 7 injects outside air into the lower air guide hood 4, increasing the air pressure inside. This causes the air to pass through the dust collection screen 3 and move upwards. As the soybean seeds move forward, they collide with each other, causing the dust adhering to their surfaces to fall off. The fallen dust rises under the blowing of the upward airflow. Simultaneously, the dust pump 11, in conjunction with the upper dust collection hood 9, sucks up the rising dust and discharges it to... The dust collection box 10 stores dust, which can reduce dust generation during gravity separation. The upper dust collection hood 9 is sealed to the guide trough by a folded rubber belt 14. One end of the folded rubber belt 14 is fixed to the fixed bracket 13, and the other end is fixed to the guide seat 15. The top and bottom of the folded rubber belt 14 are respectively inserted into the upper guide groove 16 and the lower guide groove 12.
