[0002] Peanuts are a popular food. When processing peanuts, it is often necessary to sort them by size so that they can be used for different purposes or sold according to their quality. Peanut sorting machines are devices used to sort peanut pods.

[0003] According to a public notice (Announcement No.: CN212310060U), the above application describes a new type of multi-stage peanut sorting machine that uses a material equalization mechanism to uniformly transport peanut pods to a sorting screen. The sorting screen openings gradually increase in size from the feeding end to the discharge end, thus achieving multi-stage sorting of peanut pods. This effectively solves the problem of uneven peanut pod sorting and results in high sorting efficiency.

[0004] While the oscillating motion of the screen can shake off materials stuck in the screen holes, the oscillation amplitude cannot be adjusted, making it unsuitable for screening peanut pods of different sizes and moisture levels, thus affecting the equipment's versatility and sorting efficiency.

[0005] The purpose of this invention is to provide a novel multi-stage peanut sorting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a peanut sorting device, comprising a frame, a fixed bracket hinged to the inner wall of the frame via a fixed rod, a slot extending to its side wall provided on the inner wall of the fixed bracket, a sorting sieve plate inserted into the slot, a sliding groove provided on the side wall of the frame, a swinging assembly provided inside the sliding groove, the swinging assembly comprising a slider slidably connected inside the sliding groove, one side of the slider being hinged to the side wall of the fixed bracket via a telescopic rod, the other side of the slider being fixedly connected to a connecting shaft, an adjusting rod rotatably connected to the end of the connecting shaft, a sleeve plate sleeved on the outer wall of the adjusting rod 1, an adjusting rod slidably connected inside the sleeve plate, protrusions fixedly connected to the surfaces of the adjusting rod 1 and the adjusting rod 2, the two sets of protrusions being threadedly connected by a bidirectional threaded rod, a rotating wheel fixedly connected to the end of the bidirectional threaded rod, a hinged rod hinged to the end of the adjusting rod 2, a disc rotatably connected to the side wall of the hinged rod, the disc rotatably connected to the side wall of the frame.

[0007] Preferably, a conveying assembly is provided below the fixed frame. The conveying assembly includes two sets of symmetrically arranged conveying rollers. The conveying rollers are rotatably connected between the inner walls of the frame. The two sets of conveying rollers are connected by a conveyor belt. Both ends of the conveying rollers are fixedly connected to an extension shaft. The extension shaft passes through and is rotatably connected to the side wall of the fixed frame. A drive wheel is fixedly connected to the end of one set of extension shafts. The drive wheel is connected to a disc via a synchronous belt. A motor is fixedly connected to the side wall of the frame. The output shaft of the motor is fixedly connected to the end of the other set of extension shafts.

[0008] Preferably, a limiting component is provided on the side wall of the fixing frame. The limiting component includes a horizontal plate, which is fixedly connected to the side wall of the fixing frame. Two sets of symmetrically arranged positioning rods are fixedly connected to the surface of the horizontal plate. A limiting block is fixedly connected to the end of the positioning rod.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a peanut sorting device, including a frame 1, with four sets of symmetrically arranged support legs 11 fixedly connected to the bottom surface of the frame 1, and a fixed frame 2 hinged to the inner wall of the frame 1 by a fixed rod. The inner wall of the fixed frame 2 has a slot 21 extending to its side wall, and a sorting sieve plate 22 is inserted into the slot 21. A handle is provided on the side wall of the sorting sieve plate 22 to facilitate the removal of the sorting sieve plate 22 from the slot 21 for replacement, so as to perform more accurate peanut sorting.

[0023] The side wall of the frame 1 is provided with a slide groove 3, and the inside of the slide groove 3 is provided with a swing assembly 4. The swing assembly 4 is used to swing the fixed frame 2 and the sorting screen plate 22. The swing assembly 4 includes a slider 41, which is slidably connected inside the slide groove 3. The surface of the slider 41 is provided with a through hole, and a guide rod 42 is slidably connected in the through hole. The guide rod 42 is fixedly connected to the inner wall of the slide groove 3. One side of the slider 41 is hinged to the side wall of the fixed frame 2 through a telescopic rod. The guide rod 42 is used to position the slider 41 so that the slider 41 can move stably in the vertical direction inside the slide groove 3. When the slider 41 moves up and down, the slider 41 drives one side of the fixed frame 2 to move synchronously through the telescopic rod. At the same time, the other side rotates at the hinge point between the fixed rod and the inner wall of the frame 1, thereby causing the peanuts on the sorting screen plate 22 to shake. Peanuts of different sizes are sorted through the screen holes of the sorting screen plate 22 with gradually decreasing apertures. A connecting shaft 43 is fixedly connected to the other side of the slider 41. An adjusting rod 44 is rotatably connected to the end of the connecting shaft 43. A sleeve plate 441 is sleeved on the outer wall of the adjusting rod 44. An adjusting rod 45 is slidably connected inside the sleeve plate 441. A protrusion 46 is fixedly connected to the surface of the adjusting rod 44 and the adjusting rod 45. The two sets of protrusions 46 are threaded together by a bidirectional threaded rod 47. A rotating wheel 48 is fixedly connected to the end of the bidirectional threaded rod 47. A through groove 49 for sliding of the two sets of protrusions 46 is opened on the surface of the sleeve plate 441. A hinge rod 410 is hinged to the end of the adjusting rod 45. A disc 411 is rotatably connected to the side wall of the hinge rod 410. The disc 411 is rotatably connected to the side wall of the frame 1. The rotation of the disc 411 causes the hinge rod 410 to rotate around the center of the disc 411, which in turn causes the adjusting rod 45, the sleeve plate 441, and the adjusting rod 44 to drive the slider 41 to move up and down via the connecting shaft 43. The rotating wheel 48 causes the bidirectional threaded rod 47 to drive the two sets of protrusions 46 to move towards each other or away from each other, thereby adjusting the distance between the adjusting rod 44 and the adjusting rod 45. When the distance between the adjusting rod 44 and the adjusting rod 45 decreases, the distance the slider 41 moves up and down decreases, and the swing amplitude of the sorting screen plate 22 decreases. When the distance the slider 41 moves up and down increases, the swing amplitude of the sorting screen plate 22 increases, thus adapting to the screening needs of peanut pods of different sizes and moisture content.

[0024] A conveying assembly 5 is installed below the fixed frame 2. The conveying assembly 5 includes two sets of symmetrically arranged conveying rollers 51, which are rotatably connected between the inner walls of the frame 1. The two sets of conveying rollers 51 are connected by a conveyor belt 52. Multiple arrays of protruding strips 53 are fixedly connected to the surface of the conveyor belt 52. The protruding strips 53 form protrusions on the surface of the conveyor belt 52, which separate the peanut pods that fall onto the conveyor belt 52 after being sorted by the sorting screen 22, thereby preventing the sorted peanut pods from re-aggregating. Both ends of the conveying rollers 51 are fixedly connected to extension shafts 54, which pass through and are rotatably connected to the side wall of the fixed frame 2. A drive wheel 55 is fixedly connected to the end of one set of extension shafts 54. The drive wheel 55 is connected to the disc 411 via a synchronous belt 56. A motor 57 is fixedly connected to the side wall of the frame 1, and the output shaft of the motor 57 is fixedly connected to the end of the other set of extension shafts 54. Two sets of extension shafts 54 connect the output shaft of motor 57 to transmission wheel 55. Motor 57 drives conveyor roller 51 to rotate, and conveyor belt 52 conveys peanut pods on the surface. At the same time, transmission wheel 55 drives disc 411 to rotate through synchronous belt 56, so that swing component 4 and conveyor component 5 work at the same time.

[0025] A limiting component 6 is provided on the side wall of the fixed frame 2. The limiting component 6 is used to lock the sorting screen plate 22 and prevent it from falling off during the screening process. The limiting component 6 includes a horizontal plate 61, which is fixedly connected to the side wall of the fixed frame 2. Two sets of symmetrically arranged positioning rods 62 are fixedly connected to the surface of the horizontal plate 61. The ends of the positioning rods 62 are fixedly connected to limiting blocks 63. A T-shaped plate 64 is slidably connected to the outer wall of the positioning rods 62. The T-shaped plate 64 and the limiting block 63 are elastically connected by a return spring 65. A limiting plate 66 is fixedly connected to the bottom surface of the T-shaped plate 64 and is slidably connected to the bottom surface of the horizontal plate 61. The horizontal plate 61 forms a support platform on the side wall of the fixed frame 2. The positioning rods 62 play a role in positioning and guiding the T-shaped plate 64, so that the T-shaped plate 64 can move the limiting plate 66 vertically. The limiting block 63 restricts the movement range of the T-shaped plate 64, allowing the T-shaped plate 64 to move within the length range of the positioning rod 62, thus preventing it from detaching. The limiting block 63 also provides a support point for the top of the return spring 65. Through the elastic force of the return spring 65, the T-shaped plate 64 drives the limiting plate 66 to move downwards and contact the side wall of the sorting screen plate 22, locking the sorting screen plate 22.

[0026] In this utility model, during use, according to the peanut pod screening requirements, by pulling the T-shaped plate 64 upward, the return spring 65 is compressed, causing the limiting plate 66 to disengage from the sorting screen plate 22. Holding the handle of the sorting screen plate 22, it is pulled out horizontally along the slot 21. The matching sorting screen plate 22 is aligned with the slot 21 and slowly pushed in. The T-shaped plate 64 is released, and the return spring 65 pushes the limiting plate 66 to contact the side wall of the screen plate, completing the locking.

[0027] The peanuts to be sorted are placed on the sorting screen plate 22. By rotating the rotating wheel 48, the bidirectional threaded rod 47 can drive the two sets of protrusions 46 to move towards each other or away from each other, thereby adjusting the distance between the adjusting rod 1 44 and the adjusting rod 2 45. When the distance between the adjusting rod 1 44 and the adjusting rod 2 45 decreases, the distance the slider 41 moves up and down decreases, and the swing amplitude of the sorting screen plate 22 decreases. When the distance the slider 41 moves up and down increases, the swing amplitude of the sorting screen plate 22 increases. The power of the motor 57 is turned on, and the output shaft of the motor 57 directly drives a set of conveyor rollers 51 to rotate. The conveyor rollers 51 drive another set of conveyor rollers 51 to rotate synchronously through the conveyor belt 52, and the conveyor belt starts running. The transmission wheel 55, which is coaxial with the conveyor rollers 51, drives the disc 411 to rotate through the synchronous belt 56. The disc 411 drives the hinge rod 410 to perform a circular motion, and the hinge rod 410 pushes the adjusting rod 2 45 to perform a reciprocating linear motion. Adjusting rod 2 45 drives slider 41 to reciprocate on guide rod 42 via sleeve plate 441 and adjusting rod 1 44, thereby causing fixed frame 2 and sorting screen plate 22 to oscillate periodically. Peanuts of different sizes pass through the screen holes in different areas and fall onto the surface of conveyor belt 52. They are separated by multiple sets of convex strips 53 to prevent peanuts from piling up again. Conveyor belt 52 transports the graded peanuts to the discharge port, and peanuts from different areas are received by corresponding collection containers.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
