A stable conveyor to prevent vegetables from stacking

Abstract

This invention discloses a stable conveyor for preventing vegetable stacking, relating to the field of conveyor technology. The conveyor body has two sets of fixed frames fixedly connected to its upper surface, each set having a limiting groove. A movable plate is slidably connected inside the limiting groove, and an abutment mechanism is provided below the movable plate. In this stable conveyor for preventing vegetable stacking, during the deformation and compression of the abutment plate, the first soft cavity inside is compressed, causing gas inside the first soft cavity to enter a connected second soft cavity. This causes the second soft cavity to inflate and expand. The expanded second soft cavity pushes a swing plate to rotate outward around the positioning seat, thereby causing the partition plate below the swing plate to swing outward. This pushes the stacked vegetables compressed by the deformation abutment plate towards both sides of the conveyor body, evenly dispersing the vegetables concentrated in the middle of the conveyor and further preventing the vegetables from stacking in one place.

Description

Technical Field

[0001] This invention relates to the field of conveyor technology, specifically to a stable conveyor that prevents vegetables from piling up. Background Technology

[0002] Vegetable conveyors are commonly used conveying equipment in the vegetable transportation and processing process. They are mainly used to transport and transfer sorted and cleaned vegetables to facilitate subsequent processing.

[0003] To overcome the aforementioned shortcomings, existing technology 1 (Chinese Patent No. CN214022031U, Publication Date: 2021-08-24) discloses a conveying device for highland vegetable production and processing, comprising a conveyor frame, conveyor rollers, columns, sorting components, and a swing motor. The conveyor frame is arranged symmetrically in a C-shape in two sets, with a pair of conveyor rollers rotatably connected between the two sets. A conveyor belt is wound around the outer surface of each pair of conveyor rollers. Four columns are arrayed on the upper surface of the two sets of conveyor frames, with the ends of the four columns away from the conveyor frame fixedly connected to a mounting frame. Two relatively parallel rotating rods are movably inserted inside the mounting frame, and sorting components are staggered on the outer surfaces of the two rotating rods. The sorting components include a sliding sleeve movably fitted onto the outer surface of the rotating rods, a first sorting plate fixedly connected to the lower end of the sliding sleeve, a positioning sleeve fixedly connected to the upper end of the sliding sleeve, and a positioning rod movably inserted inside the positioning sleeve. This device is easy to adjust, has high sorting efficiency, and can be widely used.

[0004] There is also prior art 2 (Chinese patent CN215972498U, published on 2022-03-08) which describes an automatic vegetable packaging machine with sorting function, relating to the field of vegetable processing technology. This automatic vegetable packaging machine with sorting function includes a first collection box and a sorting mechanism. A second collection box is provided on one side of the first collection box. Both the first and second collection boxes have open tops. Conveyor belts are installed inside both the first and second collection boxes, arranged vertically. Before packaging potatoes, the machine performs sorting, allowing potatoes to be sorted according to size, thus facilitating subsequent packaging. This effectively increases the neatness and aesthetics of the packaged potatoes, while also preventing poor sealing after lamination due to inconsistent potato sizes. This significantly improves the overall packaging effect and facilitates its promotion and use.

[0005] In existing vegetable conveyors, vegetables tend to pile up on the conveyor surface during transport. Large vegetables tend to concentrate in one spot on the conveyor belt, which not only affects the uniform processing of vegetables in subsequent steps, but also causes unstable transport and makes vegetables prone to slipping. Some conveyors with anti-piling mechanisms have fixed structures that cannot be adapted to vegetables of different sizes. Moreover, they often use fixed baffles to block and separate the vegetables, which can easily scratch the vegetable skin during separation and affect the appearance of the vegetables.

[0006] Therefore, we propose a stable conveyor to prevent vegetable stacking in order to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a stable conveyor that prevents vegetables from piling up, in order to solve the problems mentioned in the background art, such as the inability to adapt to vegetables of different sizes in the current market, and the fact that vegetables are mostly separated by fixed baffles, which can easily scratch the surface of the vegetables and affect their appearance.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a stable conveyor for preventing vegetable stacking, comprising a conveyor body, two sets of fixed frames fixedly connected to the upper surface of the conveyor body, and each set of fixed frames having a limiting groove inside, and a movable plate slidably connected inside the limiting groove. An abutting mechanism is provided below the movable plate. The abutting mechanism separates vegetables with uneven stacking volume by abutting against the conveyed vegetables through the deformation of the deformation abutting plate contained therein, preventing large vegetables from stacking in one place. A swinging mechanism is provided inside the movable plate and on its side. The swinging mechanism further pushes the stacked vegetables to the side through the deformation of the deformation abutting plate, and works with the abutting mechanism to evenly distribute the stacked vegetables on the surface of the conveyor body.

[0009] Preferably, an adjusting screw is threadedly connected to the upper part of the fixed frame, and the lower end of the adjusting screw is rotatably connected to the side of the upper surface of the moving plate. The moving plate is driven to move vertically by the threaded engagement between the adjusting screw and the fixed frame. An auxiliary roller is rotatably connected to the center of the lower surface of the moving plate.

[0010] Preferably, the outer side of the auxiliary roller is made of rubber, and the outer surface of the auxiliary roller is in contact with the vegetables to be transported. The auxiliary roller further limits the height of the transported vegetables to prevent the vegetables from stacking too high. At the same time, the rubber material can provide cushioning when in contact with the vegetables to prevent scratching the vegetable skin.

[0011] Preferably, the abutment mechanism includes a groove, which is located inside the lower part of the movable plate, and a slider is slidably connected inside the groove, while a deformable abutment plate is fixedly connected to the inner side of the slider.

[0012] Preferably, the deformable contact plate has an inclined structure on both sides, and in the initial state, the lower surface of the deformable contact plate is lower than the lower surface of the moving plate. The deformable contact plate is made of elastic rubber. When the vegetables pass under the deformable contact plate, they will squeeze the deformable contact plate to cause elastic deformation. The inclined part of the contact plate unfolds to both sides, thereby pushing the slider to slide along the groove to both sides of the moving plate.

[0013] Preferably, a return spring is fixedly connected between the interior of the deformable contact plate and the moving plate, and the return springs are distributed on both sides of the deformable contact plate to further ensure that the deformable contact plate quickly returns to its original position after deformation.

[0014] Preferably, the swing mechanism includes a movable groove, which is opened on the lower side of the movable plate. A positioning seat is fixedly connected to the side of the movable plate, and a swing plate is rotatably connected to the positioning seat. The swing plates are arranged at equal intervals, and the inner end of the swing plate extends into the interior of the groove.

[0015] Preferably, a partition plate is fixedly connected to the lower outer side of the swing plate, and the lower side of the partition plate is set in an inclined structure. The partition plate effectively separates the conveyed vegetables and avoids the vegetables from being piled up in the middle of the conveyor.

[0016] Preferably, a first soft cavity is fixedly connected between the inner upper surface of the deformable contact plate and the movable plate, a positioning plate is fixedly connected inside the movable groove, and a second soft cavity is fixedly connected to the side of the positioning plate. The other side of the second soft cavity is fixedly connected to the side of the swing plate. A connecting hose is connected through the second soft cavity and the first soft cavity, and the swing plate is driven to rotate by the expansion of the second soft cavity.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) A movable plate is provided. When transporting vegetables, the movable plate can be moved vertically under the action of the limiting groove by rotating the adjusting screw according to the vegetables being transported. This allows the movable plate to be adjusted to a suitable height to adapt to the transport of vegetables of different sizes, ensuring the stable implementation of subsequent dispersion and anti-stacking work. At the same time, the movable plate itself can initially limit the stacking height of vegetables by blocking the vegetables. The auxiliary roller made of rubber can block the upper stacked vegetables without damaging the vegetable skin, reducing the probability of vegetable stacking. (2) When the stacked vegetables pass under the deformation contact plate, the stacked vegetables will squeeze the deformation contact plate to cause elastic deformation because the sides of the deformation contact plate are set in an inclined structure. During the deformation process, the deformation contact plate will push the sliders at both ends to drive the deformation contact plate to slide to both sides of the groove. The deformation contact plate can further separate the stacked vegetables that have been initially blocked, so that vegetables with uneven volume will not be piled up in one place, and smaller vegetables will not be stuck in the gaps of larger vegetables to form a pile. (3) During the deformation and compression process of the deformation contact plate, the first soft cavity inside will be squeezed, so that the gas inside the first soft cavity enters the connected second soft cavity, causing the second soft cavity to be filled and expanded. The expanded second soft cavity pushes the swing plate to rotate around the positioning seat to the outside of the moving plate, thereby driving the partition plate below the swing plate to swing outward, pushing the stacked vegetables squeezed by the deformation contact plate to both sides of the conveyor body, dispersing the vegetables concentrated in the middle of the conveyor evenly, and further preventing the vegetables from being piled up in one place. (4) When the vegetables pass through, the reset spring will pull the deformation contact plate to quickly reset, the first soft cavity will recover its deformation, and the gas in the second soft cavity will flow back into the first soft cavity, so that the swing plate will drive the partition plate to reset synchronously, and wait for the next stack of vegetables to pass through before it will act again. The overall structure has strong linkage, and the dispersion and anti-stacking operation can be completed without additional power components, reducing the cost of equipment use, while ensuring that the vegetables can be evenly distributed on the surface of the conveyor body to achieve stable conveying. (5) In the initial state, the partition plate is set on both sides below the moving plate. The partition plate can separate and guide the transported vegetables, so that the vegetables can be evenly distributed on the transport surface during the transport process, avoiding the vegetables from being concentrated in the middle of the conveyor, thereby further reducing the possibility of vegetables stacking and ensuring the stability of the overall transport process. At the same time, the inclined lower end of the partition plate can also prevent the sharp edges from scratching and damaging the vegetable skin, ensuring the integrity of the vegetables after transport.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: As Figure 1 - Figure 3 The present invention provides the following technical solution: a stable conveyor for preventing vegetable stacking. Two sets of fixed frames 2 are fixedly connected to the upper surface of the conveyor body 1. Each set of fixed frames 2 has a limiting groove 5 inside. A movable plate 4 is slidably connected inside the limiting groove 5. An auxiliary roller 9 is rotatably connected to the center of the lower surface of the movable plate 4. The outer surface of the auxiliary roller 9 is made of rubber, and the outer surface of the auxiliary roller 9 contacts the vegetables to be conveyed. The auxiliary roller 9 further limits the height of the conveyed vegetables, preventing excessive stacking. Simultaneously, the rubber material provides protection when in contact with the vegetables. To cushion and prevent scratching the vegetable skin, an adjusting screw 3 is threadedly connected to the upper part of the fixed frame 2, and the lower end of the adjusting screw 3 is rotatably connected to the side of the upper surface of the moving plate 4. The adjusting screw 3 and the fixed frame 2 are threaded together to drive the moving plate 4 to move vertically. An auxiliary roller 9 is rotatably connected to the center of the lower surface of the moving plate 4. The outer side of the auxiliary roller 9 is made of rubber, and the outer surface of the auxiliary roller 9 is in contact with the vegetables to be conveyed. The auxiliary roller 9 further limits the height of the conveyed vegetables to prevent the vegetables from stacking too high. At the same time, the rubber material can provide cushioning when in contact with the vegetables to prevent scratching the vegetable skin.

[0022] When vegetables are being transported, the height of the moving plate 4 can be adjusted according to the size of the vegetables. By rotating the adjusting screw 3 on the top of the fixed frame 2 and using the threaded connection between the adjusting screw 3 and the fixed frame 2, the moving plate 4 can be driven to move vertically along the limiting groove 5 inside the fixed frame 2. After the moving plate 4 is adjusted to the appropriate height for vegetable transport, it stops rotating and the transport operation can begin. When vegetables pass under the moving plate 4, stacked vegetables that exceed the height limit will be blocked by the moving plate 4 and stop behind to wait for the previous batch of vegetables to pass, thus preventing the stacking layers from being too high. At the same time, the rubber auxiliary roller 9 can provide cushioning when in contact with the vegetables to prevent scratching the vegetable skin, thus initially completing the limitation on the stacking height of vegetables.

[0023] Example 2: Figure 4 - Figure 6 The present invention provides the following technical solution: a stable conveyor for preventing vegetable stacking. A contact mechanism is provided below the moving plate 4. This contact mechanism separates vegetables with uneven stacking volumes by using a deformable contact plate 8 within it to resist the deformation of the conveyed vegetables, preventing large vegetables from stacking together. The contact mechanism includes a chute 10, which is located inside the lower part of the moving plate 4. A slider 11 is slidably connected inside the chute 10, and a deformable contact plate 8 is fixedly connected to the inner side of the slider 11. The deformable contact plate 8 has inclined sides. In the initial state, the lower surface of the deformable contact plate 8 is lower than the lower surface of the moving plate 4. The deformable contact plate 8 is made of elastic rubber. When the vegetables pass under the deformable contact plate 8, they will squeeze the deformable contact plate 8 to cause elastic deformation. The inclined part of the contact plate 8 unfolds to both sides, thereby pushing the slider 11 to slide along the slide groove 10 to both sides of the moving plate. A return spring 13 is fixedly connected between the interior of the deformable contact plate 8 and the moving plate 4. The return spring 13 is distributed on both sides of the deformable contact plate 8. The return spring 13 further ensures that the deformable contact plate 8 quickly returns to its original position after deformation.

[0024] When smaller vegetables pass under the deformable contact plate 8 without being blocked by the moving plate 4, stacked together with larger vegetables, the stacked vegetables will squeeze the elastic rubber deformable contact plate 8, causing it to deform elastically. This will cause the sliders 11 on both sides of the deformable contact plate 8 to slide along the groove 10 towards both sides of the moving plate 4. The larger vegetables are initially squeezed by the deformable contact plate 8, thus slowing down the conveying speed. The smaller vegetables can pass through the gaps between the larger vegetables first, achieving natural separation of vegetables of different sizes and preventing smaller vegetables from getting stuck in the gaps between the larger vegetables and forming a continuous stack. After the batch of vegetables has completely passed under the deformable contact plate 8, the deformable contact plate 8 can be quickly pulled back to its original position under the pulling force of the return springs 13 on both sides, waiting for the next batch of stacked vegetables to pass.

[0025] Example 3: Figure 7 - Figure 9 The present invention provides the following technical solution: a stable conveyor for preventing vegetable stacking, wherein a swing mechanism is provided inside and on the side of the moving plate 4, and the swing mechanism further pushes the stacked vegetables to the side through the deformation action of the deformation abutment plate 8, and in conjunction with the abutment mechanism, evenly disperses the stacked vegetables on the surface of the conveyor body 1. The swing mechanism includes a movable groove 12, which is opened on the lower side of the moving plate 4. A positioning seat 18 is fixedly connected to the side of the moving plate 4, and a swing plate 6 is rotatably connected to the positioning seat 18. The swing plates 6 are arranged at equal intervals, and the inner end of the swing plate 6 extends into the interior of the slide groove 10. A partition plate 7 is fixedly connected to the lower outer side of the swing plate 6, and the lower side of the partition plate 7 is set in an inclined structure. The partition plate 7 effectively separates the conveyed vegetables and prevents the vegetables from being piled up in the middle of the conveyor. A first soft cavity 15 is fixedly connected between the inner upper surface of the deformation contact plate 8 and the moving plate 4. A positioning plate 17 is fixedly connected inside the movable groove 12, and a second soft cavity 16 is fixedly connected to the side of the positioning plate 17. The other side of the second soft cavity 16 is fixedly connected to the side of the swing plate 6. A connecting hose 14 is connected through the second soft cavity 16 and the first soft cavity 15. The swing plate 6 is driven to rotate by the expansion of the second soft cavity 16.

[0026] During the upward deformation of the deformation contact plate 8 under pressure, it simultaneously compresses the first soft cavity 15, causing the gas in the first soft cavity 15 to flow into the second soft cavity 16 through the connecting hose 14. After the second soft cavity 16 is inflated, its volume expands, pushing the swing plate 6 to rotate around the positioning seat 18 to the outside of the moving plate 4. This causes the partition plate 7 below the swing plate 6 to swing outward synchronously, pushing the stacked vegetables concentrated in the middle of the conveyor body 1 to both sides, so that the vegetables are evenly distributed on the conveying surface of the conveyor body 1, avoiding the vegetables from continuously being concentrated in the middle. After the vegetables pass through, the deformation contact plate 8 is reset under the action of the return spring 13, the first soft cavity 15 returns to its original shape, and the gas in the second soft cavity 16 flows back to the first soft cavity 15. The second soft cavity 16 contracts, causing the swing plate 6 and the partition plate 7 to reset, waiting for the next action. The whole process does not require additional power and can automatically complete the dispersion operation by relying on the force of the vegetable compression, effectively reducing the operating cost of the equipment. At the same time, the lower end of the inclined partition plate 7 will not scratch the vegetables, ensuring the integrity of the vegetables after conveying.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
