Description

Technical Field

[0001] This invention relates to the field of agricultural product conveying technology, specifically to an agricultural product material detection and conveying device and its operating method. Background Technology

[0002] Agricultural product material testing and conveying devices are mechanical systems specifically designed for automated material transfer in agricultural product testing processes. Their core function is to achieve efficient automated testing and improve testing accuracy and efficiency. Agricultural product material testing covers a wide range of items, typically including safety tests such as pesticide residue testing, heavy metal and trace element testing, and veterinary drug and antibiotic residue testing, as well as quality indicator testing such as nutritional component analysis and physical property testing. It is a core link in ensuring the safety and quality of agricultural products. The conveying mechanism achieves efficient automated material flow through modular design. It typically consists of a drive unit, conveyor belt, tensioning mechanism, and frame. The drive unit drives the active roller to rotate, which pulls the conveyor belt through friction. The driven roller is responsible for tensioning and guiding, ensuring appropriate belt tension, preventing slippage or deviation, ensuring smooth material movement, and reducing damage to agricultural products. After harvesting, agricultural products often have soil and impurities adhering to their surface, especially root vegetables that grow underground, which have a larger amount of soil adhering to their surface. The soil adhering to the surface of agricultural products may carry heavy metals, microorganisms, or environmental pollutants, interfering with the detection results of pesticide residues, fungal toxins, and other target substances, resulting in a significant impact of soil impurities on the detection results. Existing batch cleaning of agricultural products usually uses water washing methods. During the water washing process, water-soluble pesticides may be washed away, leading to lower detection values. Moreover, if the product is not thoroughly dried after washing, the residual moisture will dilute the sample extract, reducing the detection sensitivity. It is difficult to effectively clean the soil and impurities on the surface of agricultural products without affecting the detection results. Therefore, we propose an agricultural product material detection and conveying device and its operating method. Summary of the Invention

[0003] The purpose of this invention is to provide an agricultural product material detection and conveying device and its operating method to solve the problems mentioned in the background art.

[0006] Preferably, a rotating shaft is rotatably installed inside the feed hopper, and a transmission mechanism is provided between the end of the rotating shaft and the end of one of the roller shafts. Several baffles for preventing materials from falling rapidly are fixedly installed on the rotating shaft, and the baffles are arranged in multiple layers in a circular pattern.

[0007] Preferably, a plurality of elastic rods are fixedly connected between the lower end of the support plate and the inner wall of the feed hopper, and a wedge-shaped strip is fixedly installed at the lower end of the support plate, the wedge-shaped strip being located on the movement trajectory of the baffle.

[0008] Preferably, a plurality of electric shafts are rotatably mounted on the lower end of the cover plate in the opposite direction to the rotation of the cleaning roller, and a sponge tube is fixedly mounted on each of the electric shafts.

[0009] Preferably, each nozzle has a guide rod fixedly installed on both sides, and a plurality of limiting plates are fixedly installed on the lower end of the cover plate. Each limiting plate corresponds to a nozzle, and each limiting plate is provided with an arc-shaped groove that cooperates with the guide rod. A sliding frame is slidably installed on the lower end of the cover plate, and the sliding frame is provided with a plurality of guide grooves that cooperate with the guide rod. One of the electric shafts has a reciprocating screw groove at its end, and a limiting ring is sleeved on the electric shaft. A guide block that cooperates with the reciprocating screw groove is fixedly installed on the inner wall of the limiting ring, and a connecting rod is fixedly connected between the limiting ring and the sliding frame.

[0010] Preferably, the cover plate is configured to be upturned at the end near the feed hopper, and several rubber rollers for limiting the material are rotatably installed below the upturned end of the cover plate.

[0011] Preferably, a plurality of sliding members are symmetrically fixedly installed at both ends of the conveyor belt, and each sliding member corresponds to a support rod. Each sliding member has a slider slidably installed inside it, and each slider is fixedly connected to the inner wall of the sliding member with a spring. The slider is located at one end of the conveyor belt movement direction inside the sliding member, and the lower end of each support rod is fixedly connected to the corresponding slider.

[0012] Preferably, both the conveyor belt and the guide plate are provided with a number of through holes for the falling of soil and impurities. The edge of each through hole is rounded to prevent scratching the material. A dust collection bin for collecting soil and impurities is fixedly installed at the bottom of the frame.

[0013] An operating method for an agricultural product material detection and conveying device specifically includes the following steps: S1. Check the equipment's operating status and perform a deep cleaning to prevent any residual dirt or impurities. S2. Select root and tuber agricultural products and pour them into the feed hopper. The materials fall orderly onto the guide plate through the gap between the support plate and the inner wall of the feed hopper, and are divided into several groups by the partition. Then start the equipment. S3. When the motor is working, it drives the conveyor belt to move. At the same time, the roller shaft drives the rotating shaft and the baffle to rotate in opposite directions. Each row of baffles pushes the corresponding row of material on the guide plate to roll downwards. The material can fall accurately between two adjacent cleaning rollers. Then the material is pressed between the two cleaning rollers by the rubber roller. After the gears and racks at both ends of the cleaning roller mesh, the cleaning roller rotates and cleans the material. At the same time, the electric shaft drives the sponge cylinder to rotate. The sponge cylinder prevents the material from falling out of the clamp of the two cleaning rollers and improves the cleaning effect of the material. S4. While the material is being cleaned, the airflow generated by the blower blows downward through the nozzle. The limit ring drives the sliding frame to slide back and forth along the electric shaft. The guide rod drives the nozzle to swing back and forth along the arc groove. The dirt and impurities cleaned off the material are blown to both sides of the conveyor belt and fall into the dust collection bin through the through holes on the conveyor belt and the gap between the conveyor belt and the inner walls of both sides of the frame. The cleaned material finally rolls down onto the discharge plate in an orderly manner. S5. After the material is conveyed, clean the entire equipment again to prevent residual dirt and impurities from contaminating the next batch of materials.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a motor to drive a conveyor belt in continuous motion. After the material falls between two cleaning rollers, it is held by the two cleaning rollers and conveyed backward with the movement of the conveyor belt. When the gears at both ends of the cleaning rollers move to the meshing position with the rack, they will drive the cleaning rollers to rotate, so that the cleaning rollers clean the material. The friction between the material and the cleaning rollers causes the material to rotate continuously, and every surface of the material can be cleaned, reducing the impact of dirt and impurities on the material on subsequent material inspection. At the same time, the airflow output by the blower is continuously blown onto the conveyor belt and the material through the nozzle, improving the cleaning effect on the material.

[0015] 2. This invention utilizes a support plate to support the material. The material falls orderly from the gap between the support plate and the inner wall of the feed hopper onto the guide plate and is divided into several groups by partitions. During the rotation of each row of baffles, a corresponding row of material on the guide plate will roll downwards, and this row of material can fall between two adjacent cleaning rollers, so that a similar number of rows of material can be placed between each two cleaning rollers, which facilitates the subsequent cleaning of the material one by one. At the same time, the support plate continuously shakes up and down, reducing the phenomenon of material getting stuck in the gaps and shaking off loosely adhered dirt and impurities on the material.

[0016] 3. This invention utilizes an electric shaft to drive the sponge cylinder to rotate, preventing the material from detaching from the clamping of the two cleaning rollers. The rotation of the sponge cylinder improves the cleaning effect on the material. When the sponge cylinder and the cleaning rollers come into contact, they can also clean each other. During the rotation of the electric shaft, the limiting ring will drive the sliding frame to slide back and forth along the electric shaft, causing the guide rod to drive the nozzle to swing back and forth along the arc groove. The airflow angle blown out by the nozzle changes continuously, and the dirt and impurities cleaned off the material are blown to both sides of the conveyor belt and fall into the dust collection bin through the through holes on the conveyor belt and the gaps between the conveyor belt and the inner walls of both sides of the frame, reducing the phenomenon of dirt and impurities re-adhering to the material.

[0019] 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.

[0020] Please see Figures 1-11This invention provides a technical solution: an agricultural product material detection and conveying device, comprising a frame 1, an inlet hopper 2 and an outlet plate 14 fixedly installed at both ends of the frame 1, two roller shafts 4 rotatably installed inside the frame 1, a conveyor belt 5 driven between the two roller shafts 4, a motor 3 fixedly installed on the frame 1, the output end of the motor 3 being fixedly connected to the end of one of the roller shafts 4, a plurality of support rods 9 symmetrically arranged on both sides of the conveyor belt 5, and a cleaning roller 10 rotatably installed between every two corresponding support rods 9, the cleaning roller 10 being located above the conveyor belt 5 but not in contact with it, each cleaning roller 10 being composed of... Made of elastic sponge material, several sliding parts 6 are symmetrically fixedly installed at both ends of the conveyor belt 5. Each sliding part 6 corresponds to a support rod 9. A slider 7 is slidably installed inside each sliding part 6. A spring 8 is fixedly connected between each slider 7 and the inner wall of the sliding part 6, and the slider 7 is located at one end of the conveyor belt 5 in the direction of movement inside the sliding part 6. The lower end of each support rod 9 is fixedly connected to the corresponding slider 7. Guide rails 12 for limiting the support rods 9 are fixedly installed on the inner walls of both sides of the frame 1. A rack 13 is fixedly installed on the top inner wall of each guide rail 12. Each cleaning roller 10 has a rack 13 at both ends. A gear 11, which meshes with the rack 13, is fixedly installed. After the motor 3 starts, it drives one of the roller shafts 4 to rotate. The two roller shafts 4 keep the conveyor belt 5 taut at all times. The conveyor belt 5 moves continuously under the drive of the roller shafts 4, which in turn drives the sliding parts 6 on both sides and the cleaning rollers 10 to move synchronously. When the material falls between two adjacent cleaning rollers 10, the cleaning rollers 10 drive the support rods 9 and sliders 7 at both ends to slide within the corresponding sliding parts 6 to accommodate materials of different sizes. After the material falls between the two cleaning rollers 10, it is clamped by the two cleaning rollers 10 and will move with the conveyor belt 5. The conveyor belt 5 is conveyed in the direction of movement. At the same time, the support rod 9 is limited by the guide rail 12. The support rod 9 will pull the sliding part 6 to provide a certain support for the conveyor belt 5, reducing the phenomenon of deformation of the conveyor belt 5 under pressure. When the cleaning roller 10 moves, the gears 11 at both ends also slide in the guide rail 12. After the gears 11 move to the meshing position with the rack 13, they will drive the cleaning roller 10 to rotate, so that the cleaning roller 10 cleans the material. The friction between the material and the cleaning roller 10 makes the material rotate continuously, and each surface of the material can be cleaned, reducing the impact of dirt and impurities on the material on subsequent material inspection.

[0021] An inclined support plate 20 is provided inside the feed hopper 2. A gap is provided between the support plate 20 and the inner wall of the feed hopper 2 to allow the material to fall in an orderly manner. Below the support plate 20, a guide plate 15 is provided with the opposite inclination direction. The guide plate 15 is fixedly installed on the inner wall of the feed hopper 2. Several partitions 16 are fixedly installed on the guide plate 15. The upper end of each partition 16 is wedge-shaped. A rotating shaft 17 is rotatably installed inside the feed hopper 2. A transmission mechanism 19 is provided between the end of the rotating shaft 17 and the end of one of the roller shafts 4 (the transmission mechanism 19 is an existing belt and gear transmission device, so it will not be described in detail in this invention). Several baffles 18 are fixedly installed on the rotating shaft 17 to prevent the material from falling rapidly. The baffles 18 are multi-faceted. The layers are arranged in a circular pattern. Several elastic rods 21 are fixedly connected between the lower end of the support plate 20 and the inner wall of the feed hopper 2. A wedge-shaped strip 22 is fixedly installed at the lower end of the support plate 20. The wedge-shaped strip 22 is located on the movement trajectory of the baffle 18. Several through holes 23 for soil and impurities to fall off are provided on both the conveyor belt 5 and the guide plate 15. The edge of each through hole 23 is rounded to prevent scratching the material. A dust collection bin 24 for collecting soil and impurities is fixedly installed at the bottom of the frame 1. After the material is poured into the feed hopper 2, it will first fall onto the support plate 20 and slide down along the upper slope of the support plate 20. Then, it will fall orderly onto the guide plate 15 through the gap between the support plate 20 and the inner wall of the feed hopper 2. When the material on the guide plate 15 passes through the partition 16, it will fall onto the guide plate 15. Divided into several groups in an orderly manner, the roller 4 drives the rotating shaft 17 to rotate in the opposite direction through the transmission mechanism 19. Since the rotation speed of the rotating shaft 17 driving the baffle 18 is limited, the material on the guide plate 15 cannot continuously roll down onto the conveyor belt 5, preventing the material from accumulating on the conveyor belt 5. During the rotation of the baffle 18, each row of baffles 18 will push the corresponding row of material on the guide plate 15 to roll down, and this row of material can fall precisely between two adjacent cleaning rollers 10, so that a similar number of rows of material can be placed between each two cleaning rollers 10. Since the spacing between each row of baffles 18 is the same, each row of baffles 18 pushes the material between the lower end of the partition 16 and the lower end of the guide plate 15, even if there are differences in volume between different materials. However, the amount of material that the area can accommodate is always within a certain range, and the materials of the same batch grow in the same environment, so their size is usually within a certain range. Therefore, the amount of material in each row should be similar. When the rotating shaft 17 drives the baffle 18 to rotate, each row of baffles 18 will contact the inclined surface of the wedge strip 22, pushing the support plate 20 to move upward slightly. Then the support plate 20 will be reset under the pull of the elastic rod 21, so that the support plate 20 will continuously shake up and down, reducing the phenomenon of material getting stuck in the gap between the support plate 20 and the inner wall of the feed hopper 2. During the shaking process, the loosely adhered soil and impurities on the material can be shaken off and finally fall along the inclined surface of the guide plate 15 or its through hole 23 into the dust collection bin 24 for collection.

[0022] A cover plate 25 is fixedly installed on the frame 1. The end of the cover plate 25 near the feed hopper 2 is designed to be upturned. Several rubber rollers 28 for limiting the material are rotatably installed below the upturned end of the cover plate 25. When the material is too large to fall directly between the two cleaning rollers 10, it will come into contact with the rubber rollers 28 as it is conveyed. The rubber rollers 28 rotate to reduce friction with the material, and the material will be pressed downward between the two cleaning rollers 10. A blower 29 is fixedly installed on the cover plate 25. Several hoses 30 are connected to the output end of the blower 29. Each hose 30 is fixedly installed with a nozzle 31 for spraying airflow. Each nozzle 31 is located below the cover plate 25. The lower end of the cover plate 25 is rotatably mounted. There are several electric shafts 26 rotating in the opposite direction to the cleaning roller 10. A sponge tube 27 is fixedly installed on each electric shaft 26. Guide rods 32 are fixedly installed on both sides of each nozzle 31. Several limiting plates 33 are fixedly installed at the lower end of the cover plate 25. Each limiting plate 33 corresponds to a nozzle 31. Each limiting plate 33 is provided with an arc-shaped groove 34 that cooperates with the guide rod 32. A sliding frame 35 is slidably installed at the lower end of the cover plate 25. The sliding frame 35 is provided with several guide grooves 36 that cooperate with the guide rods 32. One of the electric shafts 26 has a reciprocating screw groove 37 at its end, and a limiting ring 38 is sleeved on the electric shaft 26. A guide groove that cooperates with the reciprocating screw groove 37 is fixedly installed on the inner wall of the limiting ring 38. A connecting rod 40 is fixedly connected between block 39, limit ring 38, and sliding frame 35. When the conveyor belt 5 conveys materials, the electric shaft 26 drives the sponge cylinder 27 to rotate. When the two cleaning rollers 10 rotate, the material between them will rotate in opposite directions due to friction. During the rotation, it may move upward due to friction. The sponge cylinder 27 can prevent the material from detaching from the clamps of the two cleaning rollers 10. Moreover, the sponge cylinder 27 rotates in the same direction as the material, which can improve the cleaning effect on the material. When the rotating sponge cylinder 27 comes into contact with the cleaning rollers 10, they can clean each other and reduce the adhesion of dirt and impurities. While the material is being cleaned, the airflow generated by the blower 29 blows downward through the nozzle 31. During the rotation of the electric shaft 26, the airflow is blown downward through the nozzle 31. The cooperation between the guide block 39 inside the limiting ring 38 and the reciprocating screw groove 37, as well as the limiting of the sliding frame 35 by the cover plate 25, causes the limiting ring 38 to drive the sliding frame 35 to slide back and forth along the electric shaft 26. The limiting of the guide rod 32 on the nozzle 31 by the guide groove 36 on the sliding frame 35, and the limiting of the guide rod 32 by the arc groove 34 on the limiting plate 33, causes the guide rod 32 to drive the nozzle 31 to swing back and forth along the arc groove 34. The airflow angle blown out by the nozzle 31 changes continuously, and the dirt and impurities cleaned off the material are blown to both sides of the conveyor belt 5 and fall into the dust collection bin 24 through the through hole 23 on the conveyor belt 5 and the gap between the conveyor belt 5 and the inner walls on both sides of the frame 1, reducing the phenomenon of dirt and impurities adhering to the material again.

[0023] Specifically, firstly, the material is poured into the feed hopper 2. The material slides downwards along the inclined surface of the support plate 20, and falls orderly onto the guide plate 15 through the gap between the support plate 20 and the inner wall of the feed hopper 2. It is then orderly separated into several groups by the partition plate 16. Then, the motor 3 is started, causing the conveyor belt 5 to drive the sliding parts 6 on both sides and the cleaning rollers 10 to move synchronously. The roller shaft 4 drives the rotating shaft 17 to rotate in the opposite direction. During the rotation of the baffles 18, each row of baffles 18 will push the corresponding row of material on the guide plate 15 to roll downwards, and the row of material can fall accurately between two adjacent cleaning rollers 10, so that each... A similar amount of material can be placed between the two cleaning rollers 10. Simultaneously, each row of baffles 18 contacts the inclined surface of the wedge-shaped strip 22, causing the support plate 20 to continuously vibrate up and down. This reduces the likelihood of material getting stuck in the gap between the support plate 20 and the inner wall of the feed hopper 2. During the vibration, loosely adhering dirt and impurities are shaken off. After falling between the two adjacent cleaning rollers 10, the material is conveyed and comes into contact with the rubber roller 28, being pressed downwards between the two cleaning rollers 10. The cleaning rollers 10 drive their end support rods 9 and sliders 7 to move relative to the corresponding sliding parts 6. The inner sliding mechanism accommodates materials of different sizes. The material is then conveyed backward by the conveyor belt 5. When the gears 11 at both ends of the cleaning roller 10 move to the meshing position with the rack 13, they drive the cleaning roller 10 to rotate, thus cleaning the material. While the conveyor belt 5 is conveying the material, the electric shaft 26 drives the sponge cylinder 27 to rotate. The sponge cylinder 27 prevents the material from detaching from the grip of the two cleaning rollers 10. Since the sponge cylinder 27 rotates in the same direction as the material, it improves the cleaning effect. When the rotating sponge cylinder 27 contacts the cleaning roller 10, they clean each other. As the material is cleaned, the airflow generated by the blower 29 blows downward through the nozzle 31. During the rotation of the electric shaft 26, the limiting ring 38 drives the sliding frame 35 to slide back and forth along the electric shaft 26. The guide rod 32 drives the nozzle 31 to swing back and forth along the arc groove 34. The angle of the airflow blown out by the nozzle 31 changes continuously. The dirt and impurities cleaned off the material are blown to both sides of the conveyor belt 5 and fall into the dust collection bin 24 through the through hole 23 on the conveyor belt 5 and the gap between the conveyor belt 5 and the inner walls on both sides of the frame 1. The cleaned material finally rolls down onto the discharge plate 14 in an orderly manner.

[0024] An operating method for an agricultural product material detection and conveying device specifically includes the following steps: S1. Check the equipment's operating status and perform a deep cleaning to prevent any residual dirt or impurities. S2. Select root and tuber agricultural products and pour them into the feed hopper 2. The materials fall orderly onto the guide plate 15 through the gap between the support plate 20 and the inner wall of the feed hopper 2, and are orderly divided into several groups by the partition plate 16. Then start the equipment. S3, when motor 3 is working, it drives conveyor belt 5 to move. At the same time, roller shaft 4 drives rotating shaft 17 and baffle 18 to rotate in opposite directions. Each row of baffles 18 pushes a corresponding row of material on guide plate 15 to roll downwards. The material can fall accurately between two adjacent cleaning rollers 10. Then the material will be pressed between the two cleaning rollers 10 by rubber roller 28. After the gears 11 and racks 13 at both ends of the cleaning roller 10 mesh, the cleaning roller 10 rotates and cleans the material. At the same time, electric shaft 26 drives sponge cylinder 27 to rotate. Sponge cylinder 27 prevents the material from falling out of the clamp of the two cleaning rollers 10 and improves the cleaning effect of the material. S4. While the material is being cleaned, the airflow generated by the blower 29 blows downward through the nozzle 31. The limiting ring 38 drives the sliding frame 35 to slide back and forth along the electric shaft 26. The guide rod 32 drives the nozzle 31 to swing back and forth along the arc groove 34. The dirt and impurities cleaned off the material are blown to both sides of the conveyor belt 5 and fall into the dust collection bin 24 through the through hole 23 on the conveyor belt 5 and the gap between the conveyor belt 5 and the inner walls on both sides of the frame 1. The cleaned material finally rolls down onto the discharge plate 14 in an orderly manner. S5. After the material is conveyed, clean the entire equipment again to prevent residual dirt and impurities from contaminating the next batch of materials.

10. An operating method for an agricultural product material detection and conveying device, characterized in that: The operating method of the agricultural product material detection and conveying device according to claim 9 specifically includes the following steps: S1. Check the equipment's operating status and perform a deep cleaning to prevent any residual dirt or impurities. S2. Select root and tuber agricultural products and pour them into the feed hopper (2). The materials fall orderly from the gap between the support plate (20) and the inner wall of the feed hopper (2) onto the guide plate (15) and are orderly divided into several groups by the partition plate (16). Then start the equipment. S3. The motor (3) works, driving the conveyor belt (5) to move. At the same time, the roller shaft (4) drives the rotating shaft (17) and the baffle (18) to rotate in opposite directions. Each row of baffles (18) pushes the corresponding row of materials on the guide plate (15) to roll downwards. The row of materials can fall accurately between two adjacent cleaning rollers (10). Then the material will be pressed between the two cleaning rollers (10) by the rubber roller (28). After the gears (11) at both ends of the cleaning roller (10) mesh with the rack (13), the cleaning roller (10) rotates and cleans the material. At the same time, the electric shaft (26) drives the sponge cylinder (27) to rotate. The sponge cylinder (27) prevents the material from falling out of the clamping of the two cleaning rollers (10) and improves the cleaning effect of the material. S4. While the material is being cleaned, the airflow generated by the blower (29) blows downward through the nozzle (31). The limiting ring (38) drives the sliding frame (35) to slide back and forth along the electric shaft (26). The guide rod (32) drives the nozzle (31) to swing back and forth along the arc groove (34). The dirt and impurities cleaned off the material are blown to both sides of the conveyor belt (5) and fall into the dust collection bin (24) through the through hole (23) on the conveyor belt (5) and the gap between the conveyor belt (5) and the inner wall on both sides of the frame (1) and are collected. The cleaned material finally rolls down onto the discharge plate (14) in an orderly manner. S5. After the material is conveyed, clean the entire equipment again to prevent residual dirt and impurities from contaminating the next batch of materials.
