Technical Field

[0001] The present invention relates to the technical field of agricultural product processing, and in particular to primary processing equipment for edible agricultural products. Background Art

[0002] Traditional processing equipment usually adopts a modular separation design, with each process running independently and requiring manual connection operations. The cleaning modules are mostly fixed water tanks or drum cleaning machines, and cleaning is achieved through manual or simple mechanical stirring. During transportation, most of them rely on manual handling, which makes materials prone to stacking and damage.

[0003] The existing processing equipment requires manual transfer of some cleaned materials to transfer equipment, and manual placement is required for cutting, which is inefficient and easily affected by human factors. Manual connection of various processes further leads to low equipment processing efficiency. During the transfer and cutting process, due to manual intervention, the material is easily damaged, which greatly reduces the overall functionality of the equipment.

[0004] Therefore, in order to solve the problem that the above-mentioned processing equipment manually connects the various processes, has low efficiency, and easily damages the materials during the transportation and cutting process, a primary processing equipment for edible agricultural products can be designed. Summary of the Invention

[0005] In order to overcome the problem that existing processing equipment manually connects various processes, has low efficiency, and is easy to damage materials during transportation and cutting.

[0006] The technical solution is as follows: A primary processing equipment for edible agricultural products, including a cleaning tank, an equipment support frame installed at the bottom of the side end of the cleaning tank, an upper end of the equipment support frame located on one side of the cleaning tank is installed with a transfer mechanism for transporting the cleaned edible agricultural products, a guide discharging mechanism for unloading the transported edible agricultural products according to individual categories is installed on the side of the transfer mechanism away from the cleaning tank, a material support frame is installed below the guide discharging mechanism, a transverse belt conveyor is installed on the inner side of the material support frame, a cutting mechanism for slicing the edible agricultural products transported to the transverse belt conveyor is installed on the upper end of the material support frame, a door-type frame plate is fixedly connected to the upper end of the cleaning tank, a first cylinder is installed at the center of the upper end of the door-type frame plate, a movable transverse plate is installed at the output end of the first cylinder, the lower end of the movable transverse plate is fixedly connected to a linkage rod, the lower end of the linkage rod is fixedly connected to a filter screen plate, and the bottom of the filter screen plate is inclined.

[0007] Furthermore, second cylinders are installed on both sides of the upper end of the movable horizontal plate, a control frame plate is installed on the output end of the second cylinder, and a first servo motor is installed on one side of the control frame plate.

[0008] Furthermore, an adjusting screw is installed at the output end of the first servo motor, a screw slider is threadedly connected to the outer side of the adjusting screw, and a cleaning brush is installed at the lower end of the screw slider.

[0009] Furthermore, the transfer mechanism includes an inclined lifting conveyor installed at the upper end of the equipment support frame, and multiple groups of equidistantly distributed partitions are installed on the inclined lifting conveyor.

[0010] Furthermore, the guide discharging mechanism includes a discharge inclined plate installed on one side of the inclined lifting conveyor, and two sets of limiting guide plates are fixedly connected to the upper end of the discharge inclined plate, and a guide groove is formed between the discharge inclined plate and the limiting guide plate.

[0011] Furthermore, a transverse guide plate is fixedly connected to one outer end of the limiting guide plate, and the transverse guide plate is located above the transverse belt conveyor.

[0016] The beneficial effect is: in the present invention, the first cylinder can drive the filter screen to move up and down, so that the agricultural products can be dynamically combined with soaking and brushing in the cleaning pool, avoiding manual turning and improving the cleaning efficiency. At the same time, the filter screen can filter the cleaning wastewater to prevent impurities from remaining, and it is also convenient for subsequent transfer processing. The transfer mechanism can separate and transport the cleaned agricultural products to prevent stacking and squeezing.

A first servo motor 108 is installed on one side of the control frame plate 107. The cleaning tank 1 serves as the core pretreatment unit of the equipment and is made of food-grade 304 stainless steel, which has good corrosion resistance and easy cleaning. The bottom of the filter plate 105 is tilted to facilitate the rapid discharge of sewage after cleaning, avoiding secondary contamination of agricultural products caused by residual sewage. At the same time, the tilt angle is 5°-10°, which can make the agricultural products slide naturally toward the transfer mechanism, reducing energy consumption. In addition, the cleaning tank 1 can be equipped with a circulating filtration system, which realizes the reuse of cleaning water through multi-layer filters and ultraviolet sterilization devices, and the water saving rate can reach more than 60%.

[0021] An adjusting screw 109 is installed at the output end of the first servo motor 108, and a screw slider 110 is threadedly connected to the outer side of the adjusting screw 109. A cleaning brush 111 is installed at the lower end of the screw slider 110. The cleaning brush 111 adopts a quick-release structure and can be disassembled and replaced within one minute, which is convenient for equipment maintenance and cleaning and meets the hygiene requirements of the food processing industry; when cleaning root agricultural products, such as potatoes and ginger, the height of the cleaning brush 111 can be lowered by adjusting the screw 109 to increase the scrubbing force; when cleaning leafy vegetables, the height is raised and a gentle scrubbing mode is adopted.

[0022] The transfer mechanism includes an inclined lifting conveyor 201 installed at the upper end of the equipment support frame 2, and multiple groups of equidistantly distributed partitions 202 are installed on the inclined lifting conveyor 201; the belt material is made of food-grade PVC, and the surface adopts a diamond pattern design with a friction coefficient of ≥0.6 to ensure that agricultural products do not slip during transportation; the drive motor in the inclined lifting conveyor 201 is equipped with a frequency converter to meet different production rhythm requirements.

[0023] The guide discharging mechanism includes a discharge inclined plate 301 installed on one side of the inclined lifting conveyor 201. Two sets of limiting guide plates 302 are fixedly connected to the upper end of the discharge inclined plate 301. A guide groove 303 is formed between the discharge inclined plate 301 and the limiting guide plate 302. The discharge inclined plate 301 is made of smooth stainless steel mirror material with a surface roughness of Ra≤0.8μm, which reduces the sliding resistance of agricultural products and reduces friction damage to the surface. Its inclination angle has been optimized through fluid mechanics simulation and is between 30°-45°, ensuring that the material slides down at a uniform speed under the action of gravity and will not cause collision due to excessive speed.

[0024] A transverse guide plate 304 is fixedly connected to one outer end of the limiting guide plate 302, and the transverse guide plate 304 is located above the transverse belt conveyor 6. The transverse guide plate 304 can adopt a retractable structure, and the retractable length is controlled by an electric push rod. The retractable range is between 0-200mm. When processing transverse conveyor belts 6 of different widths or agricultural products of different sizes, the guide plate position can be flexibly adjusted.

[0025] Hydraulic telescopic rods 501 are installed on both sides of the material support frame 5. A limit block 502 is installed at the output end of the hydraulic telescopic rod 501, and a clamping side plate 503 is installed at the side end of the limit block 502. The hydraulic telescopic rod 501 adopts a closed-loop servo hydraulic system and is equipped with a high-precision pressure sensor and a displacement sensor. The pressure control accuracy can reach ±0.1MPa and the displacement accuracy can reach ±0.1mm. The clamping force can be automatically adjusted according to the hardness and shape of the agricultural products.

[0026] The cutting mechanism includes a control support frame 701 installed at the upper end of the material support frame 5, a second servo motor 702 is installed on the side end of the control support frame 701, and a threaded adjustment rod 703 is installed at the output end of the second servo motor 702. The control support frame 701 is constructed with high-strength aluminum alloy profiles, and the structural design is optimized through finite element analysis. The weight is reduced while ensuring rigidity, thereby reducing the overall load of the equipment.

[0027] The outer surface of the threaded adjustment rod 703 is threadedly connected to a movable sleeve 704. The lower end of the movable sleeve 704 is fixedly connected to a limit slider 705. A limit slot 706 is provided through the interior of the control support frame 701, and the limit slider 705 slides within the limit slot 706. A preloaded nut pair is used between the movable sleeve 704 and the threaded adjustment rod 703 to effectively eliminate transmission backlash and ensure the repeatable positioning accuracy of the cutting blade 709 during lateral movement. The limit slider 705 and the limit slot 706 utilize a linear guide slider structure. The guide rails are selected from the Hiwin HGH series. The sliders have built-in high-rigidity ball bearings, which have a strong load-bearing capacity and can withstand the lateral forces generated during cutting.

[0028] A mounting plate 707 is installed at the lower end of the limiting slider 705, a third cylinder 708 is installed at the lower end of the mounting plate 707, and a cutting blade 709 is installed at the output end of the third cylinder 708. The mounting plate 707 is made of thickened stainless steel, and the cutting blade 709 is made of high-carbon and high-chromium stainless steel, such as 440C. The cutting edge is vacuum quenched and the hardness reaches HRC58-62, which is sharp and durable; the blade shape can be customized according to processing requirements, and a straight blade or a serrated blade can be used.

[0029] The agricultural products are poured onto the filter plate 105 of the cleaning pool 1. The pool is filled with cleaning water. Food-grade cleaning agents can also be added to the cleaning water. The first cylinder 102 drives the movable horizontal plate 103 to descend, so that the filter plate 105 is immersed in water, and the agricultural products are soaked to remove sediment. The second cylinder 106 pushes the control frame plate 107 to move horizontally to adjust the position of the cleaning brush 111; the first servo motor 108 drives the adjustment screw 109 to rotate, driving the screw slider 110 and the cleaning brush 111 to swing up and down to scrub the surface of the agricultural products; After cleaning is completed, the first cylinder 102 raises the filter screen 105 to drain the water and prepare for transportation; The drained agricultural products are lifted up to the feed end of the inclined lifting conveyor 201 along with the filter screen 105. The partition 202 separates the agricultural products into independent units to avoid stacking and squeezing. The conveyor conveys the materials upward to the guide discharge mechanism at a set speed, such as 0.5-2m / min. The agricultural products fall from the inclined lifting conveyor 201 onto the unloading inclined plate 301 and slide down along the guide groove 303; The limiting guide plate 302 forces the agricultural products to pass through in a single file, preventing multiple pieces from falling at the same time; The transverse guide plate 304 guides the agricultural products to fall vertically into the center of the transverse belt conveyor 6 in preparation for cutting; The agricultural products are moved to the cutting area along the transverse belt conveyor 6. The hydraulic telescopic rod 501 pushes the limit block 502 and the clamping side plate 503 to clamp the materials from both sides. The clamping force can be adjusted by the hydraulic system, such as 5-10N. The second servo motor 702 drives the threaded adjustment rod 703 to rotate, driving the movable sleeve 704 and the cutting blade 709 to move horizontally above the material; The third cylinder 708 quickly presses down the cutting blade 709 to complete the slicing action, with a cutting speed between 0.5-1m / s; After the slicing is completed, each component is reset, and the transverse belt conveyor 6 continues to convey the next material, and the above process is repeated.
