[0032] As Figure 3 shown, in an alternative embodiment of the present invention, two or more cleaning grooves 51 are formed on the cleaner 46, and cleaning bristles 52 are provided on the inner wall of the cleaning grooves 51.

[0033] As Figure 1 、 Figure 2 shown, in an alternative embodiment of the present invention, a dredging component is provided on the crushing box 2.

[0034] As Figure 1 、 Figure 2As shown, in an alternative embodiment of the present invention, a transmission groove 50 is formed in the outer wall of the crushing box 2. The dredging assembly includes a connecting plate 31, a force-bearing triangular prism member 32, a second spring member 33, a first wedge block 34, a dredging strip 35, a third spring member 36, and a connecting piece 37. The connecting plate 31 is slidably connected to the inner wall of the transmission groove 50. Two or more force-bearing triangular prism members 32 are fixedly connected to the connecting plate 31. The force-bearing triangular prism member 32 extends to the outside of the crushing box 2.

[0035] The second wedge block 48 cooperates with the first wedge block 34 to form a structure for driving the dredging strip 35 to move. The lower end of the dredging strip 35 is pointed, so as to facilitate insertion into the powder in the discharge port 6 for dredging.

[0036] As Figure 1 、 Figure 2 As shown, in an alternative embodiment of the present invention, the support plate 24 is rotatably connected to the inner wall of the screening cavity 22 through a rotating shaft 23. The rotating shaft 23 guides the rotation of the support plate 24.

[0037] As Figure 1 、 Figure 2 As shown, in an alternative embodiment of the present invention, the bottom wall of the feed inlet 5 is inclined, which is convenient for soybeans to fall into the box cavity 4.

[0038] In an alternative embodiment of the present invention, a glass window is inlaid on the crushing box 2, which is convenient for users to observe the crushing situation of soybeans.

[0039] In an alternative embodiment of the present invention, a wireless module is provided in the crushing box 2, and users can remotely control the device wirelessly.

[0040] In an alternative embodiment of the present invention, the crushing box 2 is connected to a controller through an electric wire, and users can control the device through the controller.

[0041] In an alternative embodiment of the present invention, the rotating rod 7 and the crushing blade 8 are made of stainless steel. Stainless steel has high hardness and corrosion resistance functions, which are suitable for crushing soybeans.

[0042] Implementation process: the user pours soybeans into the screening chamber 22, the support plate 24 supports the soybeans, the electromagnet 16 and the motor 10 are turned on, the electromagnet 16 is energized to generate magnetic repulsion, so that the first permanent magnet 13 moves to the left, the second gear 11 disengages and engages with the first gear 9, the second gear 11 engages with the third gear 17, and the rotor of the motor 10 drives the second gear 11, the third gear 17, and the threaded rod 18 to rotate. Since the threaded rod 18 is threadedly connected to the threaded hole 55, the material transfer box 19 will move up along the side wall of the crushing box 2.

[0043] During the upward movement of the material transfer box 19, the rack 20 will drive the fourth gear 30 to rotate, the fourth gear 30 will drive the tooth plate 49 to move left, the tooth plate 49 will drive all the third magnetic strips 42 to move left, the third magnetic strips 42 will contact with the soybeans, and the third magnetic strips 42 will adsorb the magnetic substance in the soybeans. When the second permanent magnet 41 moves to below the fourth permanent magnet 45, the fourth permanent magnet 45 will magnetically attract the second permanent magnet 41, so that the second permanent magnet 41, the third magnetic strip 42, and the slide plate 39 will move upward, and the third magnetic strip 42 will leave the screening chamber 22 and move to the top of the material transfer box 19, and the third magnetic strip 42 will continue to move left into the cleaning tank 51, and the cleaning bristles 52 in the cleaning tank 51 will sweep the magnetic substance on the outer wall of the third magnetic strip 42 into the metal recovery chamber 21 for recovery, thereby completing the separation of the magnetic substance in the soybeans and improving the quality of soybean extraction.

[0044] When the screening chamber 22 moves to the left side of the feed port 5, the screening chamber 22 is connected to the feed port 5, and the pressing sheet 43 presses the second air bag 29, so that the gas in the second air bag 29 enters the first air bag 26 through the air pipe. The first air bag 26 expands and lifts the left end of the support plate 24. The support plate 24 rotates clockwise around the rotating shaft 23, and the support plate 24 tilts to the right. The soybeans on the top wall of the support plate 24 slide down under the action of gravity. After passing through the feed port 5, the soybeans fall into the box cavity 4 and wait to be crushed.

[0045] When the electromagnet 16 is turned off, the electromagnet 16 loses its magnetic force, and the transmission plate 12 is reset to the right under the elastic force of the first spring member 14. The second gear 11 meshes with the first gear 9 again, and the second gear 11 drives the first gear 9, the rotating rod 7, and the crushing blade 8 to rotate, thereby increasing the rotor speed of the motor 10. The crushing blade 8 crushes the soybeans into powder, so that the subsequent soy protein isolate extraction is more thorough.

[0046] After the pulverization is completed, the valve 47 is opened, and the powder passes through the discharge port 6 under its own gravity and falls to the bottom of the pulverization box 2. The user can receive the powder in a container and then perform subsequent deep processing on the powder to achieve soy protein extraction.

[0047] Turn on the electromagnet 16 again, reverse the motor 10, and the second gear 11 drives the third gear 17 and the threaded rod 18 to reverse, so that the material transfer box 19 descends and resets, facilitating the user to pour soybeans into the screening cavity 22 again. During the descent of the material transfer box 19, the force-applying triangular prism member 54 in the component channel 53 will push all the force-receiving triangular prism members 32 towards the box cavity 4 one by one. The first wedge block 34 will push the second wedge block 48 and the dredging strip 35 to move downward against the elastic force of the third spring member 36. The dredging strip 35 is inserted into the discharge port 6 to dredge the powder in the discharge port 6 and prevent the powder from being blocked in the discharge port 6 and unable to be discharged. When the force-applying triangular prism member 54 is separated from the force-receiving triangular prism member 32, the dredging strip 35 will move upward and reset under the elastic force of the third spring member 36, and the force-receiving triangular prism member 32 will move leftward and reset under the elastic force of the second spring member 33. In this way, the dredging strip 35 dredges the discharge port 6 multiple times.

[0048] In the case where the large crushing box 2 of the present invention is provided with a relatively high feed inlet 5, by driving with a single motor 10, the material transfer box 19 can transport soybeans from a lower position to the relatively high feed inlet 5 and enter the box cavity 4, eliminating the need for the user to climb to a high place and improving processing safety. It can also drive the crushing blades 8 to crush the soybeans, thereby improving the quality of subsequent soybean protein extraction; during the transportation of soybeans to the feed inlet 5, the third magnetic strip 42 can automatically separate and recover magnetic substances in the soybeans; when the material transfer box 19 descends and resets, the dredging strip 35 can automatically dredge the discharge port 6 to prevent powder from blocking the discharge port 6 and affecting the operation of the device.

[0049] Components, modules, mechanisms, and devices whose structures are not described in detail in the present invention are all standard components or components known to those skilled in the art. Their structures and principles can all be obtained by those skilled in the art through technical manuals or by conventional experimental methods.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
