Description
Technical Field
[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen for compound fertilizer production. Background Technique
[0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, few secondary components and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization rate and promoting high and stable yield of crops. A series of processes are required during the production of compound fertilizer, and screening is an essential step to remove unqualified products with size specifications not meeting the requirements in the product.
[0003] When the existing vibrating screen is used for screening compound fertilizer, it often only adopts a fixed screening mode. This means that when users have specific requirements for the particle size of compound fertilizer, different specifications of screening plates need to be replaced to achieve precise screening operations. For example, when it is necessary to screen out smaller particle compound fertilizer, the existing vibrating screen may be equipped with a screening plate with a larger aperture, which cannot meet the requirements. At this time, the common solution is to use other vibrating screens of different levels equipped with appropriate screening plates for re-screening. This approach not only greatly increases the screening cost because multiple vibrating screen devices of different specifications need to be purchased and maintained, but also, when it is necessary to replace the screening plate or use different levels of screening equipment, the operation becomes cumbersome, resulting in a longer screening process and affecting the overall production efficiency, which is not convenient for people to use.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0021] The present utility model provides a technical solution: as Figures 1-4As shown in the figure, in this embodiment, a vibrating screen for compound fertilizer production includes: a bracket 1, and a vibrating motor 101 is fixedly installed on one side of the bracket 1; starting the vibrating motor 101 can drive the bracket 1 to vibrate, thereby driving the screening box 2 to vibrate, generating a vibrating effect to vibrate and screen the compound fertilizer on the first screening plate 5 or the second screening plate 6.
[0022] A screening box 2, the screening box 2 is rotatably installed between the two sides of the inner wall of the bracket 1, and a rotating component 3 for driving the screening box 2 to rotate is installed on the bracket 1;
[0023] Openings 4, there are two of them, and the two openings 4 are respectively opened on one side and the bottom of the screening box 2. A first screening plate 5 is fixedly installed on one of the openings 4, and a second screening plate 6 is fixedly installed on the other opening 4;
[0024] Closing plates 7, there are two of them, and the two closing plates 7 are respectively rotatably installed on one side and the bottom of the screening box 2, and are respectively used to block the two openings 4. A driving member 8 for driving the two closing plates 7 to rotate is installed on the screening box 2;
[0025] Both the other side and the top of the screening box 2 are provided with feed ports 9. Cover plates 10 are slidably installed on the two feed ports 9. A moving component 11 for driving the two cover plates 10 to move is installed on the screening box 2. When one of the cover plates 10 closes one of the feed ports 9, the other cover plate 10 moves to open the other feed port 9.
[0026] First, the screening box 2 is installed between the two sides of the inner wall of the bracket 1, and is stably supported by the bracket 1. The vibration motor 101 is installed on one side of the bracket 1. Two openings 4 are respectively provided on one side and the bottom of the screening box 2. A first screening plate 5 and a second screening plate 6 of different specifications are fixedly installed on each opening 4. The screening holes of the first screening plate 5 and the second screening plate 6 are of different sizes to meet the screening requirements of different-sized particles. By driving the screening box 2 to rotate through the rotating assembly 3, the conversion of the screening specifications can be realized. Rotate the screening box 2 as needed so that the first screening plate 5 or the second screening plate 6 is located below for convenient screening. The closing plates 7 are respectively installed on one side and the bottom of the screening box 2 to block the corresponding openings 4 and ensure the tightness of the screening process. Feed inlets 9 are provided on the other side and the top of the screening box 2. The cover plate 10 is slidably installed on the feed inlet 9, and the movement of the cover plate 10 is realized through the moving assembly 11 to control the feeding process of the compound fertilizer. When one cover plate 10 closes one feed inlet 9, the other cover plate 10 opens the corresponding feed inlet 9 to realize the screening of the compound fertilizer and prevent the compound fertilizer from spilling out through the feed inlet 9. In addition, a driving member 8 is also installed on the screening box 2 to drive the rotation of the closing plate 7 to quickly close the first screening plate 5 or the second screening plate 6. For example, when the first screening plate 5 is in use, one closing plate 7 closes the second screening plate 6 to avoid affecting the screening of the compound fertilizer. This design not only improves the screening efficiency, reduces the screening cost, but also simplifies the operation process, makes the screening equipment more convenient to use, and meets the screening requirements of different users for the particle size of the compound fertilizer.
[0027] As Figure 1 shown, the rotating assembly 3 includes a rotating motor 31 fixedly installed on one side of the bracket 1. A first bevel gear 32 is fixedly installed at the output end of the rotating motor 31. A second bevel gear 33 is fixedly installed on one side of the screening box 2. The first bevel gear 32 and the second bevel gear 33 are meshed.
[0028] Start the rotating motor 31 to drive the first bevel gear 32 to rotate, thereby driving the second bevel gear 33, and then the screening box 2 can be rotated by an angle, and each rotation angle is 90°.
[0029] As Figure 1 shown, the driving member 8 includes two electric push rods 81 rotatably installed on one side of the screening box 2. One ends of the two electric push rods 81 are rotatably installed on one side of the screening box 2. The telescopic ends of the two electric push rods 81 are respectively rotatably connected to the two closing plates 7.
[0030] Start the electric push rod 81 to extend its telescopic end, thereby pushing the closing plate 7 to rotate and open the opening 4. The compound fertilizer can be screened through the first screening plate 5 or the second screening plate 6, and the screened and falling compound fertilizer slides down through the closing plate 7 to the designated position.
[0031] As shown Figure 1 in FIG. 1, the moving assembly 11 includes a driving motor 111 fixedly installed on the screening box 2. The output end of the driving motor 111 is fixedly installed with a main gear 112. Two toothed plates 113 are slidably installed on the screening box 2. Both of the two toothed plates 113 are engaged with the main gear 112, and the two toothed plates 113 are respectively fixedly connected to the two cover plates 10.
[0032] When the driving motor 111 is started to drive the main gear 112 to rotate, since both of the two toothed plates 113 are engaged with the main gear 112, the two toothed plates 113 can be driven to move. When one cover plate 10 closes one feed inlet 9, the other cover plate 10 moves to open the other feed inlet 9, preventing the compound fertilizer from spilling out through the feed inlet 9.
[0033] As shown Figure 1 in FIG. 2, two collecting frames 12 are symmetrically inserted into the bracket 1, and are located below the opening 4.
[0034] The two collecting frames 12 are used to collect the compound fertilizer screened out by the first screening plate 5 and the second screening plate 6 respectively. When the electric push rod 81 extends its telescopic end, the closing plate 7 can be pushed to rotate and tilt, opening the opening 4, and the screened and falling compound fertilizer falls through the closing plate 7 and slides into the collecting frame 12.
[0035] As shown Figure 4 in FIG. 3, an anti-slip pad 13 is fixedly installed at the bottom of the bracket 1, and moving wheels 14 are arranged at the bottom of the collecting frame 12.
[0036] The anti-slip pad 13 is used to increase the anti-slip effect, facilitate the stable placement of this device, and prevent it from moving randomly when vibrating. The moving wheels 14 facilitate the movement of the collecting frame 12.
[0037] As shown Figure 2 in FIG. 4, an electric telescopic rod 15 is fixedly installed at the top of the bracket 1. The telescopic end of the electric telescopic rod 15 is fixedly installed with a clamping plate 16. A clamping groove is fixedly installed on one side of the screening box 2, and the clamping plate 16 is clamped with the clamping groove.
[0038] After the screening box 2 finishes rotating, start the electric telescopic rod 15 to drive the clamping plate 16 to move, and make it engage with the clamping groove, so that after the screening box 2 rotates, it can be in a stable position, preventing deviation and rotation and affecting the use.
[0039] The present utility model provides a vibrating screen for compound fertilizer production, and the specific working principle is as follows:
[0040] When screening is required, start the drive motor 111 to drive the main gear 112 to rotate. Since both toothed plates 113 are engaged with the main gear 112, the two toothed plates 113 can be driven to move. When one cover plate 10 closes one feed inlet 9, the other cover plate 10 moves to open the other feed inlet 9, preventing the compound fertilizer from spilling out through the feed inlet 9. Start the rotation motor 31 to drive the first bevel gear 32 to rotate, thereby driving the second bevel gear 33, and then the screening box 2 can be rotated by an angle, each time by an angle of 90°, so that the first screening plate 5 or the second screening plate 6 is located directly below. The screening holes of the first screening plate 5 and the second screening plate 6 are of different sizes, meeting the screening requirements of different users for the particle size of the compound fertilizer. Start the vibration motor 101 to drive the support 1 to vibrate, thereby driving the screening box 2 to vibrate, generating a vibration effect to vibrate and screen the compound fertilizer on the first screening plate 5 or the second screening plate 6. At the same time, start the electric push rod 81, and make its telescopic end extend, so as to push the closing plate 7 to rotate and open the opening 4. The compound fertilizer can be screened through the first screening plate 5 or the second screening plate 6, and the screened and falling compound fertilizer falls and slides down through the closing plate 7 to the designated position.
