Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a high-efficiency anti-clogging screening machine for bio-organic fertilizer. Background Technology

[0002] A bio-organic fertilizer screening machine is a screening device used in the production process of bio-organic fertilizer. Its main function is to separate materials of different particle sizes in organic fertilizer to ensure that the finished organic fertilizer has uniform particles and meets the required quality standards. The screening machine mainly uses vibration to remove impurities, excessively large or small particles from the material through screens or sieves, thereby ensuring the quality of the organic fertilizer.

[0003] Existing bio-organic fertilizer screening machines mainly consist of a machine body, a screen plate, and a vibrating device. Workers need to place the bio-organic fertilizer inside the machine body and then operate the vibrating device to cause the screen plate to vibrate, thus enabling the screen plate to screen the bio-organic fertilizer. However, the aforementioned bio-organic fertilizer screening machines still have certain shortcomings in use:

[0004] 1. Bio-organic fertilizer is fertilizer obtained by processing organic matter through fermentation, decomposition and other processes. These organic materials themselves contain a certain amount of moisture, which makes the surface of bio-organic fertilizer often wet when it falls onto the screen plate. The wet bio-organic fertilizer will make it more viscous, which may cause the bio-organic fertilizer to stick to the screen plate groove during the screening process, and may lead to screen plate blockage.

[0005] Second, because bio-organic fertilizer is obtained by processing organic matter through fermentation, decomposition and other processes, it often carries some large impurities during the acquisition process. These impurities can also cause clogging of the screen plate. According to the utility model patent disclosed in patent application publication number CN220919942U, which discloses an anti-clogging screening machine for organic fertilizer production, it is necessary to first crush the larger impurities with crushing rollers and then use steel nails moving from top to bottom to clean the screen plate. This process increases the energy consumed for cleaning, and if the crushing rollers do not completely crush the larger impurities, the cleaning method using steel nails may damage the screen plate. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides a high-efficiency anti-clogging screening machine for bio-organic fertilizer, which solves the technical problem in the prior art that moist bio-organic fertilizer easily adheres to the groove of the screen plate, causing the screen plate to become clogged.

[0038] like Figures 1-7 As shown, it illustrates a high-efficiency anti-clogging screening machine for bio-organic fertilizer in one embodiment of the present invention, comprising:

[0039] The machine body 1 has a coarse discharge groove on one side and a fine discharge groove on the bottom. A feed hopper 2 is fixedly connected to the top of the machine body 1. An installation groove is located at the bottom of the front end of the inner cavity of the machine body 1. Movable grooves are located on both sides of the front and rear ends of the machine body 1. A cleaning assembly 4 is fixedly connected to the side wall of the machine body 1. The cleaning assembly 4 includes a threaded motor 20. A grooved plate 21 is slidably connected to the outer surface of the output end of the threaded motor 20. Fixed rods 22 are fixedly connected to the front and rear ends of both sides of the bottom of the grooved plate 21. A fixed connection is also fixed to the bottom of the fixed rods 22. A threaded rod 24 is rotatably connected to the front end of the top of the fixed plate 23. A gear 25 is fixedly connected to the outer surface of the threaded rod 24. A vent plate 26 is slidably connected to the outer surface of the fixed plate 23. A venting top rod 27 is fixedly connected to the top of the vent plate 26. The inner diameter of the slot of the venting top rod 27 is equal to the outer diameter of the fixed rod 22. A first limiting rod 5 is fixedly connected to the top of the movable slot. A second limiting rod 8 is fixedly connected to the side wall of the inner cavity of the machine body 1. The inner diameter of the slot of the slot plate 21 is equal to the outer diameter of the second limiting rod 8.

[0040] like Figure 4 , Figure 5 and Figure 7 As shown in this embodiment, it should be noted that the threaded motor 20 enables the slotted plate 21, the vent plate 26, and the limiting plate 23 to move laterally. The inner diameter of the slot of the slotted plate 21 is equal to the outer diameter of the venting rod 27, allowing the venting rod 27 to pass through the slotted plate 21. The threaded rod 24 enables the vent plate 26 to move up and down, and the fixing rod 22 can limit the four sides of the vent plate 26.

[0041] The drying assembly 3 includes a sealed box 16, an electric heater 17 fixedly connected to the top of the sealed box 16, an air pump 18 fixedly connected to one side of the sealed box 16, an air transmission pipe 19 fixedly connected to the other side of the sealed box 16, one end of the air transmission pipe 19 being connected to the ventilation plate 26, the side wall of the drying assembly 3 being connected to the side wall of the machine body 1, and the components of the drying assembly 3 being connected to the components of the cleaning assembly 4.

[0042] like Figure 4 As shown in this embodiment, it should be noted that the air transmission pipe 19 is a corrugated pipe. Its flexibility allows the air transmission pipe 19 to remain connected to the air vent plate 26 during the lateral and vertical movement of the air vent plate 26, and prevents it from separating from the sealed box 16. The electric heater 17 can heat the inside of the sealed box 16, and the air pump 18 can transport the gas.

[0043] The screening assembly 6 includes a buffer 10. The bottom of the buffer 10 is connected to the movable groove. The top of the buffer 10 is fixedly connected to a connecting plate 11. There are two connecting plates 11. A screening plate 12 is fixedly connected between the two connecting plates 11. The screening plate 12 is U-shaped and inclined. A screening groove is opened on the downward inclined side of the top of the screening plate 12. The fine discharge groove is located directly below the screening groove. The inner diameter of the groove on both sides of the connecting plate 11 is equal to the outer diameter of the first limiting rod 5. The bottom of the screening assembly 6 is connected to the movable groove. The two sides of the screening assembly 6 are slidably engaged with the first limiting rod 5.

[0044] like Figures 1-3 As shown in this embodiment, it should be noted that the opening of the screening trough enables the screening plate 12 to screen the bio-organic fertilizer. The U-shaped screening plate 12 can block the bio-organic fertilizer above it, thereby preventing the bio-organic fertilizer from running out of the machine body 1 through the moving trough. The setting of the buffer 10 can provide buffer protection and support for the connecting plate 11 and the screening plate 12.

[0045] The vibration drive assembly 7 includes a support frame 13, a servo motor 14 is fixedly connected to the top of the support frame 13, a cam 15 is fixedly connected to the surface of the output rod of the servo motor 14, and there are two vibration drive assemblies 7. The two vibration drive assemblies 7 are respectively connected to the front end and the rear end of the machine body 1, and the components of the vibration drive assembly 7 are in contact with the screening assembly 6.

[0046] like Figure 3 As shown in the figure, it should be noted in this embodiment that the servo motor 14 allows the cam 15 to rotate, which in turn can produce an intermittent pushing effect on the connecting plate 11.

[0047] The outer surface of the toothed plate 9 and the gear 25 are in contact with one side of the toothed plate 9. The side wall of the toothed plate 9 is connected to the mounting groove. The side of the toothed plate 9 near the center of the machine body 1 is in transmission cooperation with the components of the cleaning assembly 4.

[0048] like Figure 7 As shown in this embodiment, it should be noted that the fixedly installed toothed plate 9 causes the threaded rod 24 to rotate when it moves laterally at the toothed plate 9.

[0049] In the example of the screening machine's operation, the operator first needs to operate the air pump 18, which transmits external gas through the air transmission pipe 19 to the interior of the ventilation plate 26. The gas is then discharged through the ventilation rod 27 to the area below the screening plate 12. Next, the electric heater 17 is operated to heat the gas discharged through the ventilation rod 27, thus heating the gas discharged through the ventilation rod 27 to the screening plate 12. This heating process allows the organic fertilizer to be poured into the machine body 1 through the feed hopper 2, thereby ensuring the organic fertilizer is properly absorbed and utilized. The organic fertilizer moves above the screening plate 12, and then the servo motor 14 is activated, causing the cam 15 to intermittently push the connecting plate 11, thereby causing the connecting plate 11 and the screening plate 12 to vibrate up and down. When the organic fertilizer has not yet moved into the screening trough of the screening plate 12, the vibration of the screening plate 12 allows the organic fertilizer to repeatedly contact the heated screening plate 12, thus dehumidifying the organic fertilizer. However, when the organic fertilizer moves into the screening trough of the screening plate 12... It can be used in conjunction with a screening trough to vibrate and screen organic bio-fertilizer. After screening for a certain period of time, the servo motor 14 is first run, causing the cam 15 to push the connecting plate 11 and the screening plate 12 to the highest position. Then, the threaded motor 20 is run, causing the trough plate 21 to move the fixing rod 22, the limiting plate 23, the ventilation plate 26, and the ventilation top rod 27 to below the screening trough opened on the screening plate 12. When the limiting plate 23 moves, it causes the toothed plate 9 to generate a rotational force on the gear 25, which in turn causes the threaded rod 24 to drive the ventilation plate 26. The venting rod 27 moves upward, so when the venting rod 27 moves to the bottom of the screening groove opened on the screening plate 12, the venting rod 27 is also in a higher position. Then, the air pump 18 is run separately, so that the venting rod 27 can blow out the lightly stuck small impurities in the screening groove. Then, the servo motor 14 continues to run, so that the connecting plate 11 and the screening plate 12 move downward, so that the venting rod 27 can push out the heavyly stuck large impurities in the screening groove, thereby cleaning the impurities inside the screening groove.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
