[0003] In the process of agricultural product processing, grains (such as wheat and rice) need to be dehulled. However, grains are usually mixed with hard impurities such as stones. If they are poured directly into the dehulling equipment, it will increase friction and shorten the life of the equipment.

[0004] Therefore, it is necessary to provide an agricultural product processing peeling machine to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem that grains often contain hard impurities such as stones, which, when directly poured into peeling equipment, would increase friction and shorten the equipment's lifespan, this utility model provides an agricultural product processing peeling machine.

The return spring is sleeved on the guide rod, and its two ends are respectively connected to the inner wall of the pretreatment box and the screening frame.

[0008] Preferably, the peeling mechanism includes two peeling rollers and two rotating motors. The two peeling rollers are rotatably mounted inside the peeling box, and the two rotating motors are fixedly mounted on the peeling box. The peeling rollers are connected to the output shaft of the rotating motors via couplings.

[0009] Preferably, the peeling box is provided with an inclined plate located below the peeling roller, and a discharge port is provided on one side of the peeling box, which corresponds to the inclined plate.

[0013] Compared with related technologies, the agricultural product peeling machine provided by this utility model has the following beneficial effects:

[0014] This utility model provides an agricultural product processing peeling machine:

[0015] 1. The screening frame inside the pretreatment box can separate larger stones from grains, preventing hard impurities from entering the peeling box, reducing wear on peeling parts, effectively extending the service life of the peeling equipment, and reducing equipment maintenance and replacement costs. The drive motor drives the cam to rotate continuously, enabling the screening frame to make continuous reciprocating linear motion, allowing grain particles to tumble and jump continuously inside the screening frame, so that smaller grain particles can fall through the aperture more quickly and fully, greatly improving screening efficiency, separating grains from stones more effectively, and improving screening quality.

[0016] 2. By rotating two peeling rollers relative to each other, the contact area and contact opportunities between the grain and the peeling rollers are increased. The grain is subjected to squeezing and friction from two directions between the two rollers, which can more comprehensively and deeply break down and peel off the outer shell of the grain, significantly improving the peeling efficiency. The inclined plate provides a clear direction of movement for the peeled material. Under the action of gravity, the material naturally slides along the inclined plate towards the discharge port, improving the discharge efficiency.

[0017] 3. The negative pressure fan can create a stable negative pressure environment in the collection box, which can quickly and effectively extract the grain husks generated during the peeling process from the peeling box. The electric telescopic rod drives the baffle to block and open the discharge port to realize the discharge of materials. The exhaust port provides an additional discharge channel for the airflow in the collection box, which helps to maintain a stable negative pressure environment in the collection box.

[0024] The agricultural product processing peeling machine includes: a peeling box 1 and a pre-treatment box 2. The pre-treatment box 2 is fixedly installed on the top of the peeling box 1. The top of the pre-treatment box 2 is provided with a feed hopper 3, and the bottom of the pre-treatment box 2 is fixedly connected to a discharge pipe 4, which is connected to the top of the peeling box 1; a screening frame 5, which is located inside the pre-treatment box 2.

[0025] The screening mechanism includes a drive motor 7, a cam 8, a wheel 9, and a return spring 10. The drive motor 7 is fixedly installed on one side of the pretreatment box 2. The cam 8 is connected to the output shaft of the drive motor 7 via a coupling. The wheel 9 is rotatably installed on one end of the guide rod 6 and contacts the cam 8. The return spring 10 is sleeved on the guide rod 6, and its two ends are respectively connected to the inner wall of the pretreatment box 2 and the screening frame 5. The drive motor 7 drives the cam 8 to rotate continuously, so that the screening frame 5 can continuously perform reciprocating linear motion, allowing the grain particles to continuously tumble and jump inside the screening frame 5, so that smaller grain particles can fall through the aperture more quickly and fully, greatly improving screening efficiency and separating grains from stones more effectively, thus improving screening quality.

[0026] The peeling mechanism includes two peeling rollers 11 and two rotating motors 12. The two peeling rollers 11 are rotatably mounted inside the peeling box 1, and the two rotating motors 12 are fixedly mounted on the peeling box 1. The peeling rollers 11 are connected to the output shafts of the rotating motors 12 via couplings. The relative rotation of the two peeling rollers 11 increases the contact area and interaction opportunities between the grain and the peeling rollers 11. The grain is subjected to squeezing and friction forces from two directions between the two rollers, which can more comprehensively and deeply break down and peel off the outer shell of the grain, significantly improving the peeling efficiency.

[0027] The peeling box 1 is equipped with an inclined plate 13 located below the peeling roller 11. A discharge port 14 is provided on one side of the peeling box 1, which corresponds to the inclined plate 13. The inclined plate 13 provides a clear direction for the movement of the peeled material. Under the action of gravity, the material naturally slides along the inclined plate 13 toward the discharge port 14, thereby improving the discharge efficiency.

[0028] A collection box 15 is fixedly installed on one side of the peeling box 1. A negative pressure fan 16 is fixedly installed inside the collection box 15. A filter bag 17 for collecting grain husks is provided inside the collection box 15. The filter bag 17 is located above the negative pressure fan 16. A suction pipe 18 is fixedly connected to the top of the collection box 15. The suction pipe 18 is connected to the peeling box 1. A stable negative pressure environment can be formed inside the collection box 15 by the negative pressure fan 16, which can quickly and effectively extract the grain husks generated during the peeling process from the peeling box 1.

[0029] An electric telescopic rod 19 is fixedly installed on one side of the peeling box 1. The output rod of the electric telescopic rod 19 is provided with a baffle 20 for blocking the discharge port 14. The baffle 20 is driven by the electric telescopic rod 19 to block and open the discharge port 14, so as to realize the discharge of materials.

[0030] The bottom of the collection box 15 is provided with an exhaust port, and a cleaning door is hinged to one side of the collection box 15. The exhaust port provides an additional outlet for the airflow inside the collection box 15, which helps to maintain a stable negative pressure environment inside the collection box 15.

[0031] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] The working principle of the agricultural product processing peeling machine provided by this utility model is as follows:

[0033] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0034] In use, the grains to be peeled are poured into the pretreatment box 2 through the feed hopper 3. The grains fall into the screening frame 5 located inside the pretreatment box 2. The drive motor 7 is started, and its output shaft drives the cam 8 to rotate through the coupling. As the cam 8 rotates, due to its irregular shape, it periodically pushes the wheel 9 in contact with it. The wheel 9 is rotatably mounted on one end of the guide rod 6. Under the push of the cam 8, the wheel 9 drives the guide rod 6 to move away from the center of the pretreatment box 2. The movement of the guide rod 6 drives the screening frame 5 to move together. At this time, the return spring 10 sleeved on the guide rod 6 is... When the cam 8 rotates to a certain position and no longer applies a thrust to the wheel 9, the return spring 10 will push the screening frame 5 and the guide rod 6 towards the center of the pretreatment box 2 due to its own elastic restoring force, so that the screening frame 5 returns to the vicinity of the initial position. As the drive motor 7 continues to run, the cam 8 rotates continuously, and the screening frame 5 will make reciprocating linear motion under the combined action of the guide rod 6 and the return spring 10. In this process, grain particles smaller than the aperture of the screening frame 5 will fall through the aperture and enter the peeling box 1 through the feed pipe 4, while larger stones and other hard impurities will be trapped in the screening frame 5, thereby achieving the separation of grains and stones.

[0035] During the peeling process, the grain particles after being screened in the pretreatment box 2 smoothly enter the peeling box 1 through the feeding pipe 4. The two peeling rollers 11 start to rotate relative to each other under the drive of the rotating motor 12. The grain particles are subjected to the action of the two peeling rollers 11, and are constantly rubbed and squeezed between the two rollers. In this process, the outer shell of the grain gradually separates from the grain under the action of mechanical force, thus achieving the purpose of peeling. During this process, the negative pressure fan 16 is turned on and starts to work, forming a negative pressure environment in the collection box 15. Under the action of negative pressure, the outer shell of the grain and dust in the peeling box 1 are sucked into the collection box 15 along the suction pipe 18. The outer shell of the grain in the airflow is intercepted by the filter bag 17 and collected in the filter bag 17, while the filtered clean air is discharged from the collection box 15, thus completing the separation of the outer shell of the grain from the air.

[0036] During discharge, the electric telescopic rod 19 is activated, and the output rod of the electric telescopic rod 19 retracts. The output rod drives the baffle 20 away from the discharge port 14, and the discharge port 14 is in a fully open state. The peeled grains fall downwards under the action of gravity and land on the inclined plate 13. The inclined plate 13 has a certain inclination angle. Under the action of the component force of gravity, the material will slide along the inclined plate 13 to the lower end and will be discharged from the peeling box 1 through the discharge port 14 to enter the subsequent collection or further processing stage.

[0037] Compared with related technologies, the agricultural product peeling machine provided by this utility model has the following beneficial effects:

[0038] This utility model provides an agricultural product processing peeling machine. The screening frame 5 within the pretreatment box 2 separates larger stones from grains, preventing hard impurities from entering the peeling box 1, reducing wear on peeling components, effectively extending the service life of the peeling equipment, and lowering maintenance and replacement costs. The drive motor 7 drives the cam 8 to rotate continuously, enabling the screening frame 5 to continuously reciprocate linearly. This allows grain particles to continuously tumble and jump within the screening frame 5, allowing smaller grain particles to pass through the aperture more quickly and fully, greatly improving screening efficiency and more effectively separating grains from stones, thus improving screening quality. The relative rotation of the two peeling rollers 11 increases the contact area and interaction opportunities between the grain and the peeling rollers 11. The grain husks are subjected to extrusion and friction from two directions between the two rollers, which can more comprehensively and deeply break down and peel off the grain husks, significantly improving the peeling efficiency. The inclined plate 13 provides a clear direction of movement for the peeled material, which naturally slides along the inclined plate 13 towards the discharge port 14 under the action of gravity, improving the discharge efficiency. The negative pressure fan 16 can form a stable negative pressure environment in the collection box 15, which can quickly and effectively extract the grain husks generated during the peeling process from the peeling box 1. The baffle 20 is driven by the electric telescopic rod 19 to block and open the discharge port 14, realizing the discharge of the material. The exhaust port provides an additional discharge channel for the airflow in the collection box 15, which helps to maintain a stable negative pressure environment in the collection box 15.
