Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a tomato weeding and film removal machine. Background Technology

[0002] Weeding and film removal machines are specialized equipment used for pre-processing of agricultural products. Their main function is to automatically remove weeds, residual film, vines, and other impurities attached to or mixed in the materials before crops (such as tomatoes, beets, potatoes, etc.) enter the washing, sorting, or processing process. This equipment is usually installed on a conveying system and effectively separates impurities from useful crops through technologies such as vibrating screening, airflow separation, drum screening, or optical sorting. This avoids blockages, pollution, or malfunctions in subsequent processing equipment, improves production efficiency and product quality, and reduces the intensity and error of manual operation.

[0003] In the tomato processing stage, after the harvested fruits are transported to the workshop via conveyor belt, the weeds and residual film attached to their surface, if not removed in time at the feeding end, will enter the washing, sorting and processing equipment with the materials. This can easily cause mechanical blockage and downtime, and may also contaminate the products and affect hygiene and safety. Currently, weeding and film removal are mainly carried out by manual removal, which is not only inefficient, but also prone to missed removal. Therefore, it is necessary to improve this method. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a tomato weeding and film removal machine, which has the advantage of good weeding and film removal effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tomato weeding and film removal machine, comprising a fixed frame, an mounting frame fixedly connected to the top of the fixed frame, a powerful fan fixedly connected to the top of the mounting frame, connecting pipes and mounting pipes fixedly connected to the left and right sides of the powerful fan respectively, a collection box located to the left of the powerful fan fixedly connected to the top of the mounting frame, a fixed pipe and a filter screen fixedly connected to the left and right sides of the collection box respectively, the right side of the filter screen being fixedly connected to the left side of the connecting pipe, and the bottom end of the fixed pipe penetrating the mounting frame and extending to the outside of the mounting frame and being fixedly connected to a gas collection hood.

[0006] As a preferred embodiment of this utility model, a grid mesh is fixedly connected to the bottom of the gas collection hood, and the grid mesh is made of stainless steel.

[0007] As a preferred technical solution of this utility model, a drive motor is fixedly connected to the left side of the front of the fixed frame, and a rotating shaft is fixedly sleeved at the other end of the output shaft of the drive motor. The other end of the rotating shaft passes through the fixed frame and extends into the interior of the fixed frame, and is fixedly sleeved with an active roller.

[0008] As a preferred embodiment of this utility model, a driven roller is movably sleeved in the inner cavity of the fixed frame, and the driven roller is connected to the driving roller via a transmission belt.

[0009] As a preferred embodiment of this utility model, a rectangular plate is fixedly connected to the top of the mounting frame, and fixing blocks are fixedly connected to both the front and rear sides of the top of the inner cavity of the mounting frame. A baffle is fixedly connected to the top of the fixing frame, and a power motor is fixedly connected to the right side of the rectangular plate. A threaded rod is fixedly sleeved at the other end of the output shaft of the power motor. The other end of the threaded rod passes through the rectangular plate and extends into the interior of the rectangular plate, and a moving block is threadedly sleeved thereon. The bottom of the moving block is movably connected to the top of the mounting frame.

[0010] As a preferred embodiment of this utility model, a sleeve rod is fixedly connected to the front of the moving block, a swing rod is movably connected to the inner surface of the sleeve rod, and a rotating rod is fixedly sleeved inside the bottom of the swing rod.

[0011] As a preferred embodiment of this utility model, the other end of the rotating rod passes through the fixed block and extends into the interior of the fixed block, and is fixedly sleeved with a toggle plate, which is made of food-grade silicone.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a connecting pipe, an installation pipe, a collection box, a fixing pipe, and a gas collection hood, allows the gas collection hood to extract weeds and broken film from tomatoes located above the conveyor belt when the powerful fan is started. The impurities are sequentially drawn into the inner cavity of the collection box through the gas collection hood and the fixing pipe. At this time, the air is filtered by the filter screen and discharged from the device through the connecting pipe and the installation pipe, while the weeds and broken film remain in the collection box, achieving the function of efficiently removing weeds and broken film. Furthermore, the design of the gas collection hood can effectively expand the suction range, thereby covering the entire width of the conveyor belt and ensuring no dead corners.

[0013] 2. This utility model, by setting up a sleeve rod, a swing rod, a rotating rod, a fixed block, and a deflector plate, will drive the threaded rod to rotate when the power motor starts running. At this time, the moving block will drive the sleeve rod to move horizontally to the left along the top of the mounting frame, so that the sleeve rod squeezes the swing rod, causing the swing rod to drive the rotating rod and the deflector plate to rotate around the rotating rod as the axis. Finally, through the reciprocating motion of the moving block, the deflector plate will swing back and forth left and right, pushing aside the tomatoes piled up on the transmission belt, preventing the gas collection hood from being unable to absorb weeds and broken film due to the accumulation of tomatoes.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a tomato weeding and film removal machine, including a fixed frame 1, an mounting frame 2 fixedly connected to the top of the fixed frame 1, a powerful fan 3 fixedly connected to the top of the mounting frame 2, a connecting pipe 4 and a mounting pipe 5 fixedly connected to the left and right sides of the powerful fan 3 respectively, a collection box 6 located to the left of the powerful fan 3 fixedly connected to the top of the mounting frame 2, a fixed pipe 7 and a filter screen 9 fixedly connected to the left and right sides of the collection box 6 respectively, the right side of the filter screen 9 fixedly connected to the left side of the connecting pipe 4, and the bottom end of the fixed pipe 7 penetrating the mounting frame 2 and extending to the outside of the mounting frame 2 and fixedly connected to a gas collection hood 8.

[0018] When the powerful fan 3 is started, it will extract weeds and broken film from the tomatoes above the conveyor belt 15 through the air collection hood 8. The impurities will be drawn into the inner cavity of the collection box 6 through the air collection hood 8 and the fixed pipe 7. At this time, the air will be filtered by the filter screen 9 and discharged from the device through the connecting pipe 4 and the installation pipe 5. The weeds and broken film will remain in the collection box 6. The design of the air collection hood 8 effectively expands the suction range, thereby covering the entire width of the conveyor belt 15 and ensuring no dead corners.

[0019] The bottom of the gas collection hood 8 is fixedly connected to a grid 10, which is made of stainless steel.

[0020] The design of the grid mesh 10 can effectively prevent small tomatoes from being sucked into the gas collection hood 8 and clogging the pipes.

[0021] Among them, a drive motor 11 is fixedly connected to the left side of the front of the fixed frame 1, and a rotating shaft 12 is fixedly sleeved at the other end of the output shaft of the drive motor 11. The other end of the rotating shaft 12 passes through the fixed frame 1 and extends into the interior of the fixed frame 1, and is fixedly sleeved with an active roller 13.

[0022] When the drive motor 11 starts running, it will cause the rotating shaft 12 to drive the drive roller 13 to rotate synchronously.

[0023] The inner cavity of the fixed frame 1 is movably fitted with a driven roller 14, which is connected to the driving roller 13 via a transmission belt 15.

[0024] When the drive roller 13 rotates, it will drive the driven roller 14 to rotate synchronously through the transmission belt 15.

[0025] The mounting frame 2 is fixedly connected to the top of a rectangular plate 16. Fixing blocks 23 are fixedly connected to the front and rear sides of the top of the inner cavity of the mounting frame 2. The top of the fixing frame 1 is fixedly connected to a baffle 25. The right side of the rectangular plate 16 is fixedly connected to a power motor 17. The other end of the output shaft of the power motor 17 is fixedly sleeved with a threaded rod 18. The other end of the threaded rod 18 passes through the rectangular plate 16 and extends into the interior of the rectangular plate 16 and is threadedly sleeved with a moving block 19. The bottom of the moving block 19 is movably connected to the top of the mounting frame 2.

[0026] When the power motor 17 starts running, it drives the threaded rod 18 to rotate, thereby causing the moving block 19 to move horizontally to the left along the top of the mounting bracket 2.

[0027] Among them, the front of the moving block 19 is fixedly connected to the sleeve rod 20, the inner surface of the sleeve rod 20 is movably connected to the swing rod 21, and the bottom of the swing rod 21 is fixedly sleeved with the rotating rod 22.

[0028] When the moving block 19 drives the sleeve rod 20 to move to the left, the sleeve rod 20 will squeeze the swing rod 21, causing the swing rod 21 to drive the rotating rod 22 to swing slightly around the axis of the rotating rod 22.

[0029] The other end of the rotating rod 22 passes through the fixing block 23 and extends into the interior of the fixing block 23, and is fixedly sleeved with a toggle plate 24, which is made of food-grade silicone.

[0030] This design virtually eliminates the risk of mechanical damage, skin breakage, or bruising to tomatoes, while also preventing the materials from contaminating the product.

[0031] Working principle and usage process of this utility model: First, start the drive motor 11, causing the rotating shaft 12 to drive the active roller 13 to rotate synchronously, and the driven roller 14 to start rotating together through the transmission belt 15. At this time, the tomatoes will begin to be conveyed. Then, start the power motor 17, which drives the threaded rod 18 to rotate. At this time, the moving block 19 will drive the sleeve rod 20 to move horizontally to the left along the top of the mounting frame 2, so that the sleeve rod 20 squeezes the swing rod 21, causing the swing rod 21 to drive the rotating rod 22 and the actuating plate 24 to rotate around the rotating rod 22 as the axis. Finally, through the reciprocating motion of the moving block 19, the actuating plate 24 swings left and right, pushing away the tomatoes piled on the transmission belt 15, preventing the gas collection hood 8 from being unable to absorb weeds and broken film due to the accumulation of tomatoes.

[0032] Then, the powerful fan 3 is started. At this time, the air collection hood 8 will extract the weeds and film fragments from the tomatoes located above the conveyor belt 15. The impurities will be drawn into the inner cavity of the collection box 6 through the air collection hood 8 and the fixed pipe 7. At this time, the air will be filtered by the filter screen 9 and discharged from the device through the connecting pipe 4 and the installation pipe 5, while the weeds and film fragments will remain in the collection box 6, realizing the efficient removal of weeds and film fragments. In addition, the design of the air collection hood 8 can effectively expand the suction range, thereby covering the entire width of the conveyor belt 15 and ensuring no dead corners.
