[0024] A discharge port is provided at the lower end of the screen cylinder 7, a protective shell is fixedly connected to the outer end of the driving motor 6, an annular baffle 11 is fixedly connected to the outer end of the protective shell, and the annular baffle 11 is located at the lower end of the screen cylinder 7 and is slidably connected to the screen cylinder 7, a perforation matching the discharge port is provided at the lower end of the annular baffle 11, a cleaning box 9 is fixedly installed at the inner end of the sand removal cabinet 1, and the cleaning box 9 is located on the side of the support plate 5, a conveying pipe 8 is provided between the cleaning box 9 and the screen cylinder 7, a plurality of sand removal components 10 are fixedly installed at the inner end of the sand removal cabinet 1, and a plurality of sand removal components 10 are located above the cleaning box 9, a plurality of water spray heads 17 are fixedly connected to the inner end of the sand removal cabinet 1, and the plurality of water spray heads 17 are alternately distributed with the plurality of sand removal components 10, and the soybeans enter the conveying pipe 8 from the discharge port and fall into the cleaning box 9, the soybeans are rinsed by the water spray head 17, and the sand removal components 10 are used to remove sand from them.

[0025] The cleaning box 9 includes a containing box 91, which is fixedly installed at the inner end of the sand removal cabinet 1, and a filter screen 92 is fixedly connected to the middle of the inner end of the containing box 91. A pair of electromagnets 93 are inlaid on the inner wall of the containing box 91, and the electromagnet 93 is located above the filter screen 92. The sand removal component 10 includes an exhaust pipe 101.

The electromagnet 93 is intermittently magnetized in sequence to attract the magnetic ball 104, so that the magnetic ball 104 swings left and right to generate vibration. At the same time, the magnetic ball 104 pulls the traction rope 103 to move the cylindrical cover 102 downward to wrap and cover the upper end of the exhaust pipe 101, so that the gas is injected into the exhaust pipe 101 to generate bubbles that overflow from the water. Under the elastic force of the reset spring 106, the magnetic ball 104 resets once every swing, thereby achieving the purpose of continuously generating bubbles.

[0026] The reason why the traction rope 103 is not elastic is to prevent the magnetic balls 104 from being subjected to excessive magnetic attraction, which may cause multiple magnetic balls 104 to collide with each other or multiple traction ropes 103 to be entangled with each other.

The protective door 18 can protect the equipment in the sand removal cabinet 1 and can also be observed. It can also be opened for subsequent cleaning and collection.

[0030] The gas here can be natural gas or gas supplied by external equipment. Air can be used. The most common gas used for soybean cleaning is air. High-pressure air jets or fans are used to blow away light impurities such as dust and small particles adhering to the surface of soybeans. The advantages are low cost, easy access and simple operation. The limitation is that the air contains oxygen, which may not be applicable to certain specific situations such as those requiring an oxygen-free environment. Nitrogen can be used instead of air in the cleaning process where oxidation needs to be avoided. Nitrogen is an inert gas that can be purged and cleaned without introducing oxygen. The advantage is that it does not participate in chemical reactions and can prevent oxidation damage. The limitation is that the cost is higher than air and special supply and storage facilities are required. Carbon dioxide can be used for dry ice blasting cleaning, especially when grease or sticky dirt needs to be removed. Dry ice will subthermally expand after contacting the surface, physically stripping the dirt from the soybean surface. The advantage is that dry ice will sublimate during the cleaning process, leaving no moisture or chemical residue. The limitation is that the cost is high and special safety measures and equipment are required. Steam is not a gas, but it can be used for cleaning and disinfection when it is converted into a gas state; steam can effectively remove grease, bacteria and other organic matter; the advantage is that it can clean and disinfect at the same time with high efficiency. The limitation is that it consumes a lot of energy and requires steam generation and delivery equipment.

[0031] Working principle: The poured soybeans are pre-screened by the pre-screen 3 to remove larger impurities such as stones and larger soil blocks. Then the soybeans fall to the upper end of the conveying net 4 and collide with it. Under the impact force, part of the mud and sand on the outer surface of the soybeans can be removed and screened by the conveying net 4. The soybeans fall into the screen cylinder 7 and rotate at high speed under the drive motor 6. The centrifugal force generated by the high-speed rotation of the soybeans will throw out the fine sand particles adhering to the surface of the soybeans. At the same time, under the cooperation of the diffusion gear rod 12, the soybeans collide with it, which can make part of the mud and sand fall off. The soybeans enter the conveying pipe 8 from the discharge port and fall into the cleaning box 9, and are washed by the water spray head. 17 The soybeans are rinsed until the water submerges the soybeans and covers the magnetic ball 104 and contacts the exhaust pipe 101. The magnetic ball 104 is intermittently magnetized by the electromagnet 93 to attract the magnetic ball 104, so that the magnetic ball 104 swings left and right to generate vibration. At the same time, the magnetic ball 104 pulls the traction rope 103 to move the cylindrical cover plate 102 downward to wrap and cover the upper end of the exhaust pipe 101, so that gas is poured into the exhaust pipe 101 to generate bubbles that overflow from the water. Under the elastic force of the reset spring 106, the magnetic ball 104 resets once each time it swings, thereby achieving the purpose of continuously generating bubbles.

[0032] It can be seen from the above technical solutions that the present invention has the following beneficial effects: The present invention aims to fully remove the residual sand on the surface of soybeans in the water by vibrating the sand removal component 10 and generating bubbles. The soybeans and sand and gravel poured into the feed frame 2 are pre-screened by the pre-screen 3, and then fall into the sand removal cabinet 1 and enter the screen cylinder 7. The screen cylinder 7 is driven by the drive motor 6 to rotate at a high speed. The centrifugal force generated by the high-speed rotation is used to throw out the fine sand particles adhering to the surface of the soybeans, and then enter the conveying pipe 8 from the discharge port and slide into the cleaning box 9 at the upper end of the filter screen 92, and the water spray head 17 is used to remove the fine sand particles adhering to the surface of the soybeans. The fallen soybeans are rinsed until the water submerges the soybeans and covers the magnetic ball 104. Then, a pair of containing boxes 91 are intermittently activated to attract the magnetic ball 104, causing the magnetic ball 104 to swing left and right to generate vibration while pulling the traction rope 103, so that the cylindrical cover 102 moves down to cover the upper end of the exhaust pipe 101 and injects gas into the exhaust pipe 101, so that the gas overflows from the lower end of the exhaust pipe 101, thereby generating bubbles in the water to thoroughly remove the mud and sand adhering to the surface of the soybeans.
