Abstract
Description
Technical Field
[0001] This utility model relates to the field of vegetable sorting technology, specifically a vegetable sorting machine. Background Technology
[0002] A vegetable sorting machine is an auxiliary device used to sort vegetables. It is widely used in the field of agricultural equipment. Most vegetable sorting machines on the market work based on the screening principle of sorting rollers, which separate vegetables of different sizes through the channels formed between the sorting rollers.
[0003] Chinese utility model patent CN219597230U discloses a vegetable sorting machine, including a sorting box. Multiple sets of rotatable sorting rollers are installed on the upper part of the inner wall of the sorting box. Each sorting roller is conical, with one end wider than the other near the feed inlet. A sorting channel is provided between each set of sorting rollers, the width of which increases sequentially from the feed inlet to the discharge outlet. The sorting rollers are driven to rotate by a motor fixed outside the sorting box. This utility model relates to the field of vegetable sorting technology. This vegetable sorting machine improves upon existing sorting roller screening methods by first employing rotating sorting rollers. During the sorting process, the rotation allows vegetables of different sizes to be separated, preventing them from getting tangled together. Furthermore, by setting an oscillation mechanism on the sorting rollers, the rollers can vibrate while rotating, which effectively further promotes the separation of vegetables from each other.
[0004] The sorting rollers in existing equipment are mostly fixed installation structures, and their spacing is set during manufacturing. They cannot be flexibly adjusted according to the actual size of the vegetables to be sorted, thus creating a problem of inconvenience in adjusting the spacing of the sorting rollers.
[0005] Therefore, this utility model provides a vegetable sorting machine to solve the above problems. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a vegetable sorting machine that solves the aforementioned problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: A vegetable sorting machine includes a base. An adjustment mechanism and a protective assembly are fixedly connected to the upper surface of the base. The adjustment mechanism includes a support frame and a protective frame fixedly connected to the upper surface of the base.

A first sorting roller is slidably connected to the outer surface of the sliding block. The outer surface of the fixed plate is hinged to the outer surface of the sliding block. A second sorting roller is slidably connected to the outer surface of the sliding block. The protective assembly includes an electric telescopic rod and a fixed frame fixedly connected to the upper surface of the base. A lifting frame is fixedly connected to the output end of the electric telescopic rod. A limit rod and a fixed block are fixedly connected to the inner wall of the lifting frame. A connecting block is slidably connected to the outer surface of the limit rod. The outer surface of the connecting block is hinged to one end of the second sorting roller.

[0008] Furthermore, a geared motor is fixedly connected to the outer surface of the fixed plate, the output shaft of the geared motor is fixedly connected to the outer surface of the bidirectional threaded rod, and a feed frame is fixedly connected to the upper surface of the support frame.
[0009] By adopting the above technical solution, the output shaft of the geared motor drives the bidirectional threaded rod to rotate, and the rotation of the bidirectional threaded rod drives the two sets of moving plates to move in opposite directions, thereby facilitating the adjustment of the distance between the moving plate and the fixed plate, and facilitating the adjustment of the distance between the first sorting roller and the second sorting roller.
[0010] Furthermore, a limiting groove is formed at one end of the first sorting roller and the second sorting roller near the sliding block, a limiting block is fixedly connected to the outer surface of the sliding block, and the outer surface of the limiting block is slidably connected to the inner wall of the limiting groove.
[0011] By adopting the above technical solution, the limiting block slides on the inner wall of the limiting groove, thereby facilitating the prevention of separation between the sliding block and the first sorting roller.
[0012] Furthermore, a support telescopic rod is slidably connected to the inner wall of the fixed frame, a limit plate is fixedly connected to the lower surface of the support telescopic rod, the limit plate is slidably connected to the inner wall of the fixed frame, and the upper surface of the support telescopic rod is fixedly connected to the lower surface of the lifting frame.
[0013] By adopting the above technical solution, the support telescopic rod slides on the inner wall of the fixed frame, which facilitates the limiting of the outer surface of the lifting frame. At the same time, the limiting plate can prevent the support telescopic rod from separating from the fixed frame.
[0014] Furthermore, the protective assembly also includes a buffer net fixedly connected to the inner wall of the support frame, and a barrier net is fixedly connected to the outer surface of the buffer net.
[0015] Using the above technical solution, the buffer net helps to cushion falling vegetables, and the barrier net helps to separate vegetables of different sizes.
[0016] Furthermore, one side of the buffer net is provided with multiple sets of collection shells, and a control panel is fixedly connected to the outer surface of the base.
[0017] Using the above technical solution, collecting the outer shell makes it easier to collect vegetables of different sizes.
[0018] Beneficial effects
[0019] This utility model provides a vegetable sorting machine. Compared with the prior art, it has the following advantages:

[0031] Furthermore, a geared motor 201 is fixedly connected to the outer surface of the fixed plate 212, and the output shaft of the geared motor 201 is fixedly connected to the outer surface of the bidirectional threaded rod 208.

[0032] In this embodiment, the geared motor 201 drives the bidirectional threaded rod 208 to rotate, causing the moving plate 206 to move in the opposite direction. With the sliding connection between the sliding block 209 and the sorting roller and the limiting block 211, the distance between the first sorting roller 204 and the second sorting roller 205 can be flexibly adjusted to adapt to the sorting needs of vegetables of different sizes, ensure sorting accuracy, and complete the grading of vegetables of multiple specifications without changing the equipment, thus improving the versatility of the equipment.
[0033] Reference Figures 1 to 4 In one aspect of this embodiment, a support telescopic rod 302 is slidably connected to the inner wall of the fixed frame 301, a limit plate 304 is fixedly connected to the lower surface of the support telescopic rod 302, the limit plate 304 is slidably connected to the inner wall of the fixed frame 301, and the upper surface of the support telescopic rod 302 is fixedly connected to the lower surface of the lifting frame 308.

[0035] In this embodiment, the electric telescopic rod 303 pushes the lifting frame 308 to rise and fall, the support telescopic rod 302 assists in limiting the position, and drives one end of the sorting roller to tilt and change the angle, thereby slowing down the rolling speed of the vegetables. The falling vegetables are buffered by the buffer net 305 and separated by the barrier net 306 to reduce collision damage. At the same time, the support structure is stable, ensuring the sorting process is safe and orderly and improving the integrity of the sorted vegetables.
[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0037] Working principle: First, based on the size requirements of the vegetables to be sorted, the target distance between the first sorting roller 204 and the second sorting roller 205 is preset. After the reduction motor 201 is started, its output shaft drives the bidirectional threaded rod 208 to rotate. The bidirectional threaded rod 208 drives the two sets of moving plates 206 to move in opposite directions, thereby changing the distance between the moving plate 206 and the fixed plate 212. At this time, the sliding block 209, which is hinged to the moving plate 206, moves accordingly. The sliding block 209 slides in the limiting groove 210 at the end of the first sorting roller 204 through the limiting block 211 to prevent the two from separating, thus facilitating... The distance between the first sorting roller 204 and the second sorting roller 205 is adjusted to facilitate the sorting of vegetables of different sizes. The vegetables are then placed on the feeding frame 202 above the support frame 207. Under gravity, the vegetables slide down from the feeding frame 202 and enter the sorting area composed of the first sorting roller 204 and the second sorting roller 205. By activating the electric telescopic rod 303, the output end of the electric telescopic rod 303 pushes the lifting frame 308 up or down. Simultaneously, the support telescopic rod 302 slides against the inner wall of the fixed frame 301, facilitating protection of the output end of the electric telescopic rod 303. The movement of the lowering frame 308 causes the connecting block 310 and the fixing block 311 to move, allowing one end of the first sorting roller 204 and the second sorting roller 205 to tilt upwards or downwards. This facilitates adjustment of the tilt angle of the first sorting roller 204 and the second sorting roller 205. During this process, the sliding block 209 and the limiting groove 210 have adjustable space, providing sufficient room for adjustment of the sorting roller angle and preventing jamming. This slows down the rolling speed of the vegetables. Guided by the first sorting roller 204 and the second sorting roller 205, the vegetables, which are smaller than the sorting rollers, move downwards. Vegetables with smaller gaps between the sorting rollers fall through the gaps first, while larger ones continue to be conveyed. During this process, the sliding connection between the sliding block 209 and the sorting roller, and the cooperation between the connecting block 310 and the limiting rod 309, ensure the stable posture of the sorting roller. The falling vegetables first come into contact with the buffer net 305 on the inner wall of the support frame 207. The elasticity of the buffer net 305 reduces collision damage. Then, they fall onto the barrier net 306 on one side of the buffer net 305. The barrier net 306 further separates vegetables of different sizes according to the mesh size. Finally, the separated vegetables fall into the collection shell 307 in the corresponding position to complete the classification and collection.
