Description
Technical Field
[0001] This utility model relates to the field of vibrating screening mechanisms, specifically a soybean vibrating screening mechanism that is easy to clean and maintain. Background Technology
[0002] The soybean vibrating screen is a key piece of equipment that uses vibration to efficiently separate soybeans from impurities, and it is widely used in the initial processing stage of soybeans in agricultural processing. This equipment mainly consists of core components such as a screen box, a vibration source, and a filter screen. Its working principle is to utilize the excitation force generated by a vibrating motor or a forced synchronous vibrator to achieve particle size classification and impurity removal of the material on the screen surface under high-frequency vibration. In agricultural processing, the soybean vibrating screen not only effectively improves the purity of raw materials but also provides important quality assurance for subsequent processing techniques.
[0003] However, due to the long-term exposure to high-intensity vibration and material impact, filter screens are prone to wear and clogging, requiring disassembly and maintenance. In vibrating screening equipment, the method of fixing the filter screen directly affects its service life and ease of maintenance. Currently, common filter screen designs mainly include bolt fixing and welding fixing. However, the disadvantage of bolt fixing and welding fixing is that the disassembly process is cumbersome, especially after long-term operation, when bolts may become difficult to remove due to rust or fatigue, increasing maintenance time and costs. In contrast, snap-fit fixing, as a quick connection method, has gradually gained attention in recent years. This method uses a specially designed slot structure to allow the filter screen to be quickly embedded and locked onto the screen frame, completing installation and disassembly without additional tools.

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0015] Please see the appendix Figure 1-5 This application provides the following technical solutions.
[0016] A soybean vibrating screening mechanism that is easy to clean and maintain includes a vibrating screening machine body 1, an installation mechanism 2 is provided inside the vibrating screening machine body 1, and a screening mechanism 3 is provided on the top of the installation mechanism 2; the vibrating screening machine body 1 includes an installation box 11, and a limiting port 16 is opened on the side wall of the installation box 11; the installation mechanism 2 includes two fixed seats 23, which are slidably connected to the inner wall of the limiting port 16; two vibration springs 22 are fixedly connected to the bottom of each of the two fixed seats 23; four fixing members 21 are fixedly connected to the bottom of each of the four vibration springs 22; one end of each fixing member 21 is fixedly connected to the installation box 11; two sliding grooves 25 are opened through both sides of the fixed seats 23; sliding extrusion blocks 26 are slidably connected to the inner wall of the four sliding grooves 25; an extrusion groove is opened in the middle of the sliding extrusion block 26; an extrusion inclined surface is provided on the inner wall of the extrusion groove; a limiting plate 27 is fixedly connected to the inner wall of the fixed seat 23; one side of the limiting plate 27 is in contact with the sliding extrusion block 26.
[0017] It should be noted that during the soybean screening process, a lot of impurities may remain on the top and bottom of the filter screen 32 and in the filter holes. Long-term accumulation can easily clog the filter holes, requiring disassembly, cleaning and maintenance. The operator pulls the handle 29, causing the insert 28 to slide out of the slot 345, and at the same time, the limiting plate 27 moves along the slide groove 25, so that the fixing plug 34 is inserted into the extrusion groove. The locking block 343 contacts the extrusion inclined surface, and the return spring 344 retracts, causing the locking block 343 to be pulled into the shrinkage groove 342. After all four handles 29 are fully pulled out, the operator can pull the handle 33 to cause the mounting frame 31 to slide out along the limiting slide rail 15, and the fixing plug 34 will slide out from the inner wall of the insertion port 24, thus completing the disassembly.
[0018] The screening mechanism 3 includes four fixed inserts 34. The outer wall of the fixed insert 34 is slidably connected to the insertion port 24. The fixed insert 34 includes a fixed block 341. A shrinkage groove 342 is provided through both sides of the fixed block 341. Two locking blocks 343 are slidably connected to the inner wall of the shrinkage groove 342. The bottom of the locking block 343 is provided with a slope. A return spring 344 is fixedly connected to the opposite side of the two locking blocks 343. The middle part of the return spring 344 is fixedly connected to the fixed block 341. A slot 345 is provided through the bottom side wall of the fixed block 341. An insert 28 is inserted into the inner wall of the slot 345. One side of the insert 28 is fixedly connected to the sliding extrusion block 26. A pull handle 29 is fixedly connected to the other side of the insert 28.
[0019] It should be noted that after maintenance is completed, the operator only needs to pull the handle 33 to slide the mounting frame 31 along the limiting slide rail 15, so that the four fixing plugs 34 are inserted into the corresponding sockets 24. The locking block 343 contacts the socket 24 through the slope and is squeezed into the shrinkage groove 342. When the fixing plugs 34 reach the bottom of the inner wall of the fixing seat 23, the operator then pushes the handle 29 to move the sliding extrusion block 26 until it contacts the limiting plate 27. The plug 28 is inserted into the slot 345. The reset spring 344 pushes the locking block 343 to reset and lock it at the bottom of the socket 24 to complete the fixed installation of the screening mechanism 3.
[0020] The top of the fixed plug 34 is fixedly connected to the mounting frame 31. The inner wall of the mounting box 11 is provided with four limiting slide rails 15. The two ends of the mounting frame 31 are slidably connected to the limiting slide rails 15. The middle of the mounting frame 31 is fixedly connected to the filter screen 32. The inner wall of the mounting frame 31 is fixedly connected to the handle 33. The top of the mounting box 11 is provided with the inlet 12. The bottom of the mounting box 11 is provided with the outlet 13. The outlet 13 is located at the bottom of the mounting frame 31. The bottom of the mounting box 11 is provided with the outlet 2 14. The outlet 2 14 is located below the gap between the screening mechanism 3 and the inner wall of the mounting box 11.
[0021] It should be noted that during use, the operator starts the motor to drive the fixed seat 23 to move up and down on the inner wall of the limiting port 16 through the vibration spring 22 between the fixed seat 23 and the fixed part 21, thus vibrating. Then, soybeans are put into the installation box 11 through the input port 12 and fall to the top of the filter screen 32. The fixed seat 23 drives the screening mechanism 3 to vibrate, causing soybeans smaller than the aperture of the filter screen 32 to fall to the bottom of the installation box 11 and be discharged through the discharge port 13. Subsequently, the soybeans remaining on the top of the filter screen 32 are slowly dropped from the front end of the screening mechanism 3 and the gap between the front end of the screening mechanism 3 and the installation box 11 to the bottom of the installation box 11 and are discharged through the discharge port 24.
[0022] During use, the operator starts the motor, which drives the fixed seat 23 to move up and down on the inner wall of the limiting port 16 via the vibration spring 22 between the fixed seat 23 and the fixing part 21, causing vibration. Soybeans are then fed into the mounting box 11 through the inlet 12, falling onto the top of the filter screen 32. The fixed seat 23 drives the screening mechanism 3 to vibrate, causing soybeans smaller than the aperture of the filter screen 32 to fall to the bottom of the mounting box 11 and be discharged through the discharge port 13. Subsequently, soybeans remaining on the top of the filter screen 32, due to vibration, slowly fall from the front end of the screening mechanism 3 into the gap between the front end and the mounting box 11, and are discharged through the discharge port 24. During soybean screening, a lot of impurities easily remain on the top and bottom of the filter screen 32 and in the filter holes. Long-term accumulation can easily clog the filter holes, requiring disassembly, cleaning, and maintenance. The operator pulls the handle 29, causing the insert 28 to slide out of the slot 345, simultaneously moving the limiting plate 27 along the slide groove 25, thus fixing the insert. 34 is inserted into the extrusion groove, and the locking block 343 contacts the extrusion slope. The return spring 344 retracts, causing the locking block 343 to retract into the shrinkage groove 342. After the four pull handles 29 are fully pulled out, the operator can pull the handle 33 to move the mounting frame 31 along the limit slide rail 15 to disengage. The fixing plug 34 slides out from the inner wall of the insertion port 24, thus completing the disassembly. After maintenance, the operator only needs to pull the handle 33 to slide the mounting frame 31 along the limit slide rail 15, so that the four fixing plugs 34 are inserted into the insertion port 24 respectively. The locking block 343 contacts the insertion port 24 through the slope and is squeezed into the shrinkage groove 342. When the fixing plug 34 reaches the bottom of the inner wall of the fixing seat 23, the operator then pushes the pull handle 29 to move the sliding extrusion block 26 until it contacts the limit plate 27. The plug 28 is inserted into the slot 345. The return spring 344 pushes the locking block 343 to reset and lock it at the bottom of the insertion port 24 to complete the fixed installation of the screening mechanism 3.
