Description

A crushing device for processing perilla seeds Technical Field

[0001] This utility model relates to the field of perilla seed technology, specifically to a crushing device for processing perilla seeds. Background Technology

[0002] Perilla seeds are the fruit of Perilla frutescens, an annual herbaceous plant belonging to the genus Perilla in the family Lamiaceae. They have rich nutritional value. Their surface is grayish-brown to dark brown or yellowish-brown with raised reticulate patterns. The pointed end has a fruit stalk mark. The pericarp is thin, hard, and brittle, and easily crushed.

[0003] For example, a perilla seed crushing device with authorization announcement number "CN219540404U" can prevent crushed perilla seeds from accumulating on the feed hull during the feeding process, thus avoiding blockages and difficulty in feeding. However, this device accumulates non-sized perilla seeds on the filter screen, slowing down or even halting the screening process and reducing its processing capacity. Frequent machine stops are required to clean the filter screen, and the fixed frame makes cleaning difficult. Furthermore, the device relies solely on two crushing rollers, requiring a considerable amount of time to achieve the desired crushing degree. For large quantities of perilla seeds, the slow crushing process reduces overall production efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of inconvenience in cleaning perilla seeds left on the filter screen and the fact that relying solely on two crushing rollers to squeeze perilla seeds requires a long time to achieve the desired degree of crushing. For large quantities of perilla seeds, the crushing process is slow, reducing overall production efficiency. Therefore, this invention proposes a crushing device for processing perilla seeds.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a crushing device for processing perilla seeds, including a box body and a first shell. The right end of the box body is fixedly connected to the first shell. The interior of the first shell is provided with a filter screen flipping structure. The lower end of the box body is provided with a second discharge port. The upper end of the box body is fixedly connected to a curved plate. The outer wall of the curved plate is fixedly connected to a second shell. The interior of the second shell is provided with a perilla seed preliminary crushing structure. The inner wall of the upper end of the box body is fixedly connected to a box body.

[0007] Preferably, the filter screen flipping structure includes an electric telescopic rod, the outer wall of which is fixedly connected to the first housing, the output end of which is slidably connected to the first housing, a rack fixedly connected to the output end of which, the upper end of which is slidably connected to a slide rod, both ends of which are fixedly connected to the first housing, the rack meshing with a first gear, the rotating shaft of which is rotatably connected to the first housing via a bearing, the inner walls on both sides of the housing being rotatably connected to a round rod via sealed bearings, and the end of which is fixedly connected to the filter screen.

[0008] Preferably, a second servo motor is fixedly connected to the rear end of the housing, and a second gear is fixedly connected to the output shaft of the second servo motor. The second gear meshes with a third gear, and the rotation shafts of the second gear and the third gear are rotatably connected to the housing through sealed bearings.

[0009] Preferably, the rotating shafts of the second gear and the third gear are both fixedly connected to the crushing roller, and both ends of the crushing roller are rotatably connected to the housing through sealed bearings.

[0010] Preferably, the perilla seed preliminary crushing structure includes a first servo motor, the outer wall of which is fixedly connected to a second housing, a connecting rod fixedly connected to the output shaft of the first servo motor, both ends of the connecting rod's rotating shaft being rotatably connected to the second housing via bearings, a cylinder fixedly connected to the end of the connecting rod, the outer wall of the cylinder being slidably connected to a groove frame, sliders fixedly connected to both ends of the groove frame, the outer walls of the sliders being slidably connected to the second housing, and a pressing block fixedly connected to the lower end of the groove frame, the outer wall of the pressing block being slidably connected to the second housing.

[0011] Preferably, the lower end of the box body is provided with a first discharge port, and a guide plate is fixedly connected to the lower end of the box body.

[0012] The present invention provides a crushing device for processing perilla seeds, which has the following advantages: through the cooperation of the filter screen flipping structure and the first housing, the output end of the electric telescopic rod moves and drives the rack to slide on the slide rod. The slide rod limits the rack, causing the rack to move linearly. The rack movement drives the gear to rotate, the gear rotation drives the round rod to rotate, and the round rod rotation drives the filter screen to rotate. When the filter screen rotates 180 degrees, the unqualified perilla seeds fall into the unqualified product collection box below through the second discharge port due to gravity, thus facilitating the operator to collect the unqualified perilla seeds on the filter screen.

[0013] Through the cooperation of the initial crushing structure for perilla seeds and the second shell, the output shaft of the second servo motor rotates, driving the connecting rod to rotate. The rotation of the connecting rod causes the cylinder to slide within the groove frame, thereby moving the groove frame. The movement of the groove frame causes the slider to slide within the second shell. The slider acts as a limiter for the groove frame, ensuring that the groove frame can only move vertically. The movement of the groove frame causes the pressing block to move into the box until it contacts the perilla seeds inside the box. The pressing block then continues to move downwards, crushing most of the perilla seeds. This helps the subsequent crushing roller to crush the perilla seeds more finely and evenly, and improves work efficiency. Attached Figure Description

[0025] Referring to Figures 1, 2, and 4: The filter screen flipping structure 3 includes an electric telescopic rod 301. The outer wall of the electric telescopic rod 301 is fixedly connected to the first housing 2. The model of the electric telescopic rod 301 is selected according to actual needs, and only those that meet the working requirements are selected.

[0028] Working principle:

[0029] When using a grinding device for processing perilla seeds:

[0030] Preliminary crushing of perilla seeds:

[0031] Slide the lid on box 7 to the right to remove it. Pour the perilla seeds to be crushed into box 7. Connect the external power supply to the second servo motor 601 and start the second servo motor 601. The output shaft of the second servo motor 601 rotates, driving the connecting rod 602 to rotate. The rotation of the connecting rod 602 drives the cylinder 603 to slide in the groove of the groove frame 604 (as shown in Figure 2), thereby moving the groove frame 604. The movement of the groove frame 604 drives the slider 605 to slide in the second housing 5. The slider 605 limits the groove frame 604, allowing it to move only vertically. The movement of the groove frame 604 drives the pressing block 606 to move into the box 7 until the pressing block 606 contacts the perilla seeds in the box 7. The pressing block 606 then continues to move downwards, causing the perilla seeds to come into contact with the perilla seeds in the box 7. When the perilla seeds are crushed and the slider 605 slides to the bottom of the second housing 5, the continued rotation of the output shaft of the first servo motor 601 causes the pressing block 606 to move upward and reset. During this process, the perilla seeds in the center of the pressing block 606 are crushed, and the perilla seeds around the pressing block 606 are squeezed outward as the pressing block 606 descends. After the pressing block 606 resets, the operator can use external tools such as a rice shovel to move the uncrushed perilla seeds towards the center of the pressing block 606 and the crushed perilla seeds towards the periphery of the pressing block 606. Repeating the above operation pre-treats the perilla seeds, achieving the purpose of initial crushing, which helps the subsequent crushing roller 13 to crush the perilla seeds more finely and evenly, and improves work efficiency.

[0032] After initial crushing, the pressing block 606 is reset by the first servo motor 601, the first servo motor 601 is turned off, and the perilla seeds on the pressing block 606 are scraped into the box 7 by the scraper.

[0033] Secondary grinding:

[0034] Open the solenoid valve on the first discharge port 8. Most of the initially crushed perilla seeds fall through the first discharge port 8 onto the two crushing rollers 13, while a small portion falls onto the guide plate 9. Due to the shape of the guide plate 9 (as shown in Figure 6), the guide plate 9 has the effect of concentrating and sliding the perilla seeds. A vibration motor can be installed at the same horizontal level as the guide plate 9 on the back of the housing 1. When a small portion of the perilla seeds fall onto the guide plate 9, the vibration motor can transmit power to the guide plate 9, causing the perilla seeds on the guide plate 9 to fall between the two crushing rollers 13. Connect the external power supply of the second servo motor 10 and start the second servo motor 10. The output shaft of the second servo motor 10 rotates, driving the second gear 11 to rotate. The rotation of the second gear 11 drives the third gear 12 to rotate. The rotation of the second gear 11 and the third gear 12 rotates in opposite directions. The rotation of the two gears causes the two crushing rollers 13 to rotate inward, thereby performing secondary crushing on the perilla seeds between the two crushing rollers 13.

[0035] Place the qualified product collection box below the second discharge port 14, open the solenoid valve of the second discharge port 14, and the crushed perilla seeds enter the qualified product collection box through the second discharge port 14. Another vibration motor can be set at the same level as the filter screen 305 on the back of the box body 1. When the crushed perilla seeds fall onto the filter screen 305, the vibration motor will make the qualified products on the filter screen 305 fall off better, while the unqualified perilla seeds remain on the filter screen 305. After the qualified perilla seeds are collected, take out the qualified product collection box and place the unqualified product collection box below the second discharge port 14.

[0036] Start the electric telescopic rod 301. The output end of the electric telescopic rod 301 moves, causing the rack 302 to slide on the slide rod 303 (as shown in Figure 4). The slide rod 303 limits the rack 302, causing the rack 302 to move linearly. The movement of the rack 302 drives the gear 304 to rotate. The rotation of the gear 304 drives the round rod 306 to rotate. The rotation of the round rod 306 drives the filter screen 305 to rotate until the filter screen 305 rotates 180 degrees. Then, close the electric telescopic rod 301. The unqualified perilla seeds fall into the unqualified product collection box below through the second discharge port 14 due to gravity. After the unqualified perilla seeds are collected, remove the unqualified product collection box and reset the filter screen 305 by using the electric telescopic rod 301. It should be noted that the electric telescopic rod has a self-locking function to prevent the filter screen 305 from rotating. Turn off all power, and the working process of the crushing device for perilla seed processing is completed. The front end of the box 1 is equipped with an inspection door, which can be used to inspect the inside of the box 1.
