[0028] In the embodiment of the present application, the storage bucket 1 is arranged in a square shape, and the specifications of the storage bucket 1 are arranged according to the specific use conditions. The embodiment of the present application does not make specific restrictions, as long as the crushing roller 11, the primary screening component 2, the secondary screening component and the connecting piece 4 are all placed, the feed port 12 is arranged in a rectangular shape, the crushing roller 11 is arranged in a cylindrical shape, the crushing roller 11 is arranged horizontally along the long side direction of the feed port 12, and three crushing rollers 11 are arranged to rotate in sequence along the short side direction of the feed port 12, wherein the crushing roller 11 is driven by a servo motor 38. The collection box 13 is arranged in a rectangular shape, wherein the upper end of the collection box 13 is open, and the screened raw materials can be collected. Specifically, a closed door is arranged on one side of the storage bucket 1, and the closed door can be opened after the filtration is completed to collect the filtered materials at the bottom of the primary screening component 2 and the primary storage bucket 1.

[0029] During specific use, the crushing roller 11 is started, and oat grains are poured in from the feed port 12 to be crushed, and then the crushed oat germ, oat bran and powder fall into the primary screening component 2, and then the primary screening component 2 retains the oat germ in the primary screening component 2, and then the oat bran and powder fall into the secondary screening component, and the secondary screening component separates the oat bran and the powder, so that the powder falls into the bottom of the storage bucket 1, and the secondary screening component opens the storage bucket 1 under the action of the connecting piece 4 while separating the oat bran and the powder, so that the oat bran falls into the collecting box 13, and there is no need to replace the screen when screening the oat crushed material, thereby improving the working efficiency of oat screening.

[0030] Combination Figure 1 , Figure 2 and Figure 3In a specific embodiment, a first magnetic wheel 14 is fixedly provided on the outer peripheral side of the pulverizing roller 11 in the middle of the three pulverizing rollers 11. The primary screening assembly 2 includes a first filter screen 21, a rotating shaft 22, and a stirring paddle 24. The peripheral side of the first filter screen 21 is fixedly provided on the inner peripheral side of the storage bucket 1; the rotating shaft 22 is rotatably provided on the first filter screen 21, and a second magnetic wheel 23 is fixedly provided on the upper end of the rotating shaft 22; one end of the stirring paddle 24 is fixedly provided on the peripheral side of the rotating shaft 22.

[0031] In the embodiment of the present application, the first filter 21 is arranged in a semi-arc shape. It should be noted that the filter holes of the first filter 21 are just enough to let the oat bran and powder fall off. The rotating shaft 22 is arranged in a cylindrical shape, and the rotating shaft 22 is arranged coaxially with the first filter 21. The stirring paddle 24 is arranged in a rectangular shape, and a plurality of stirring paddles 24 are arranged at intervals along the circumference of the rotating shaft 22. The stirring paddle 24 is arranged in multiple layers at intervals along the axial direction of the rotating shaft 22, so that when the rotating shaft 22 rotates, the stirring paddle 24 can stir the oatmeal crushed materials at different heights. The stirring paddle 24 can be fixed to the rotating shaft 22 by bolts, or by bonding or bolting, which is not specifically limited in the embodiment of the present application. The first magnetic wheel 14 is arranged in a circular ring shape. It should be noted that the inner peripheral side of the first magnetic wheel 14 is fixed to the outer peripheral side of the pulverizing roller 11 in the middle of the three pulverizing rollers 11 by bonding or bolting. The fixing method is not specifically limited in the embodiment of the present application and can be set according to the specific use situation. It is only necessary to fix the first magnetic wheel 14 to the pulverizing roller 11. The second magnetic wheel 23 is arranged in a circular ring shape. The inner peripheral side of the second magnetic wheel 23 is fixed to the outer peripheral side of the rotating shaft 22 close to the pulverizing roller 11; it should be noted that the inner diameter of the second magnetic wheel 23 is smaller than the inner diameter of the first magnetic wheel 14.

[0032] During specific use, the crushing roller 11 rotates to drive the first magnetic wheel 14 to rotate. Due to the principle that like poles of magnets repel each other and unlike poles attract each other, when the first magnetic wheel 14 rotates, the magnetic pole changes. At the same time, the change in the magnetic pole of the first magnetic wheel 14 will drive the magnetic pole of the second magnetic wheel to change. Therefore, the second magnetic wheel 23 will drive the rotating shaft 22 to rotate, so that the stirring roller stirs the oatmeal crushed material, so that the oat bran and powder can fall from the first filter 21, thereby increasing the screening efficiency.

[0033] Combination Figure 2 , Figure 3 and Figure 4In a specific embodiment, the lower end of the rotating shaft 22 penetrates the first filter 21, a slide groove 52 is circumferentially arranged on the inner circumference of the storage bucket 1, and a corrugated groove 51 is circumferentially arranged on the circumference of the rotating shaft 22. The secondary screening component includes: an electric telescopic plate 31, a second filter 32, a scraper plate 33, a switch 34, a fan 35, a matching rod 36, a matching plate 37, and a driving member. Two electric telescopic plates 31 are provided, and the two electric telescopic plates 31 are fixedly arranged on the inner side wall of the storage bucket 1; the second filter 32 is slidably arranged in the slide groove 52; one end of the scraper plate 33 is fixedly arranged on the circumference of the rotating shaft 22; the switch 34 is fixedly arranged in the slide groove 52, and the switch 34 is electrically connected to the electric telescopic plate 31; the fan 35 is fixedly arranged on one side of the storage bucket 1; the matching rod 36 is horizontally arranged in the storage bucket 1, and one end of the matching rod 36 penetrates the outside of the storage bucket 1; the matching plate 37 is fixedly connected to the surrounding side of the matching rod 36; the driving member is fixedly arranged on the outside of the storage bucket 1; wherein, the electric telescopic plate 31 is located below the first filter screen 21, the second filter screen 32 is located below the electric telescopic plate 31, the matching rod 36 is located at the lower end of the second filter screen 32, and the height of the driving member is equal to that of the matching rod 36; the driving member is a motor 38, and the output shaft of the motor 38 is fixedly connected to one end of the second bevel gear 42.

[0034] In the embodiment of the present application, the chute 52 is arranged in a rectangular shape. It should be noted that the chute 52 can be arranged on the opposite sides of the storage bucket 1 or can be arranged around the storage bucket 1. The specific arrangement is based on the on-site use conditions, and the embodiment of the present application does not make specific restrictions. The corrugated groove 51 is arranged in a wave shape, so that the second filter 32 can slide up and down. It should be noted that a guide block is arranged at one end of the second filter 32 that contacts the rotating shaft 22, one end of the guide block is fixedly connected to one end of the second filter plate close to the rotating shaft 22, and the other end is slidably arranged in the wave groove. The electric telescopic plate 31 is reserved with a position for the rotating shaft 22 to pass through, and the specific aperture specifications are set according to the specific conditions of the rotating shaft 22 when used on site. The second filter 32 is arranged in a square shape, and the specifications meet the requirements for sliding in the chute 52, wherein the size of the filter hole of the second filter plate is sufficient to leak the powder and leave the oat bran on the second filter plate. The scraper plate 33 is arranged in a square shape and is arranged above the wave groove. When the second filter plate moves to the top, the oat bran can be stirred so that the powder accumulated in the oat bran can fall off. The switch 34 is arranged in a square rod shape. It should be noted that the free end of the switch 34 extends away from the bottom wall of the chute 52. The switch 34 is electrically connected to the electric telescopic plate 31 and the fan 35. When the rotating shaft 22 drives the second filter plate to move upward, the second filter plate will squeeze the open tube upward, so that the electric telescopic plate 31 and the fan 35 are started. The matching rod 36 is arranged in a cylindrical shape, and the length of the matching rod 36 is greater than the length of the storage bucket 1. The matching plate 37 is arranged in a square shape, and the specifications of the matching plate 37 meet the requirements of just closing the storage bucket 1. The fan 35 is arranged at the lower end of the second filter plate to increase the contact area with the oat bran, and at the same time, the oat bran on the second filter plate can be blown out as much as possible, which is simple and convenient.

[0035] In actual use, when the rotating shaft 22 rotates, the second filter plate slides up and down, and the switch 34 is turned on during the upward sliding process, so that the electric telescopic plate 31 extends, and the upper end of the second filter plate is closed. When the electric telescopic plate 31 extends and closes, the fan 35 is started, and when the switch 34 is turned on, the motor 38 is started, so that the motor 38 drives the matching rod 36 to rotate, and the matching rod 36 drives the matching plate 37 to rotate, and the lower end of the second filter plate is closed, so that the second filter plate forms a relatively closed space, thereby screening the oat bran simply and conveniently.

[0036] Combination Figure 2 , Figure 3 and Figure 4In a specific embodiment, a discharge port 15 is provided on one side of the storage bucket 1, and the connecting member 4 includes: a first bevel gear 41, a second bevel gear 42, a closing plate 43, and a connecting rod 44. One end of the first bevel gear 41 is fixedly arranged on the end of the matching rod 36 penetrating the outer side of the storage bucket 1; the second bevel gear 42 is fixedly connected to the driving member; the closing plate 43 is hinged to the discharge port 15 to open and close the discharge port 15; one end of the connecting rod 44 is rotatably connected to the end of the second bevel gear 42 away from the driving member, and the other end is rotatably connected to the upper end of the closing plate 43.

[0037] In the embodiment of the present application, the discharge port 15 is arranged in a rectangular shape. It should be noted that the discharge port 15 is arranged within the space where the second filter plate moves, so that the oat bran can be blown out from the discharge port 15. The closing plate 43 is arranged in a rectangular shape, and the lower end of the closing plate 43 can be connected to the discharge port 15 by a hinge or by rotating the shaft 22. It should be noted that the specification of the closing plate 43 is just enough to close the discharge port 15. The connecting rod 44 is arranged in a rectangular shape, and the length of the connecting rod 44 is sufficient to be connected to the closing plate 43. Specifically, a guide plate 16 is fixed at the upper end of the closing plate 43 to reduce the blown oat bran from falling on the motor 38 and affecting the operation of the motor 38.

[0038] During specific use, when the motor 38 is started, the output shaft of the motor 38 drives the second bevel gear 42 to rotate, and at the same time drives the first bevel gear 41 to rotate so that the matching rod 36 rotates. Since the connecting rod 44 is rotatably connected to the end of the second bevel gear 42 close to the first bevel gear 41, when the second bevel gear 42 rotates, it drives the connecting rod 44 to move downward, so that the connecting rod 44 opens the discharge port 15, so that the fan 35 blows the oat bran out of the discharge port 15 and falls into the collection box 13, thereby increasing the oat crushing and screening efficiency, which is simple and easy to operate.

[0039] The implementation principle of the embodiment of the present application is as follows: the crushing roller 11 is started, oatmeal grains are poured in from the feed port 12, so that the oatmeal grains are crushed, and then the crushed oats fall on the first filter screen 21, the crushing roller 11 rotates to drive the first magnetic wheel 14 to rotate, and the change of the magnetic pole of the first magnetic wheel 14 will drive the magnetic pole of the second magnetic wheel to change, so that the second magnetic wheel 23 will drive the rotating shaft 22 to rotate, so that the stirring roller stirs the crushed oats, so that the oat bran and powder can fall from the first filter screen 21, and then the oat bran falls on the second filter screen 32, and the powder from the second filter screen 32 falls and enters the bottom of the storage bucket 1. When the rotating shaft 22 rotates, the second filter plate slides up and down. At the same time, the switch 34 is turned on during the upward sliding process, so that the electric telescopic plate 31 extends and closes the upper end of the second filter plate. When the electric telescopic plate 31 extends and closes, the fan 35 is started. When the switch 34 is turned on, the motor 38 is started, so that the motor 38 drives the matching rod 36 to rotate, so that the matching rod 36 drives the matching plate 37 to rotate, and the lower end of the second filter plate is closed, so that the second filter plate forms a relatively closed space, thereby sieving the oat bran, which is simple and convenient. As a result, the oat germ remains on the first filter screen 21, the oat bran falls into the collection box 13, and the powder falls into the bottom of the storage bucket 1. When sieving the oat crushed material, there is no need to replace the screen, thereby improving the working efficiency of oat screening.
