Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer screening devices, in particular to a screening device for compound fertilizer processing. Background Art

[0002] In agricultural production, compound fertilizer is inevitably used. Compound fertilizer is a chemical fertilizer containing two or more essential nutrients for plants. In order to unify the particle size of compound fertilizer and ensure that crops absorb the fertilizer more evenly, a screening device for compound fertilizer processing is needed to perform preliminary screening of the compound fertilizer.

[0003] Chinese patent CN214638246U discloses a vibrating screen device for compound fertilizer particles, including a screening box, a vibrating mechanism and a screen. A screen is provided inside the screening box, and the screen is slidably connected to a chute provided on the inner wall of the screening box through a slider. A spring is welded between the bottom of the slider and the inner bottom plate of the chute. A drying box is fixed to one side wall of the screening box by welding through a bracket. The top of the drying box is conductively connected to an air inlet, and a fan is provided in the air inlet. A heating wire is provided in the drying box, and the drying box is conductively connected to the screening box through an air outlet pipe. In this utility model, three screens are provided, which can achieve four-level screening of compound fertilizer particles, maximizing its practicality. Secondly, the screen is at an angle of 30 degrees to the horizontal plane, so that the screen has a certain inclination angle. In conjunction with the setting of the vibrating mechanism, it effectively prevents the accumulation of compound fertilizer particles from causing clogging of the screen, thereby ensuring the stability and efficiency of its screening. If there are still defects that can be improved:

[0004] 1. This utility model vibrates the screen by installing a vibration mechanism at the bottom of the screen. However, the vibration mechanism is located in the middle of the bottom of the screen, which is the concentrated area where compound fertilizer falls. Small compound fertilizers can easily penetrate into the vibration mechanism, causing the vibration mechanism to fail in a short time, thereby reducing work efficiency.

[0005] 2. This utility model discharges large-particle compound fertilizer from the screening box by placing the screen at an angle of 30 degrees to the horizontal plane. However, it should be noted that since the compound fertilizer has a certain humidity during the processing process, it is very easy to stick to the screen and cause the sieve holes to be blocked. It is difficult to clean the compound fertilizer on the screen at a 30-degree angle alone, which will reduce efficiency.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0034] The present invention will be described in further detail below with reference to the accompanying drawings.

[0035] The working principle of this utility model is as follows Figures 1-6As shown, a screening device for compound fertilizer processing includes a screening box 1, a feed pipe 12 is fixedly connected to the middle of the top of the screening box 1, and the compound fertilizer to be processed enters the screening box 1 from the feed pipe 12, and then a working plate 6 is provided in the screening box 1, and the middle of the top of the working plate 6 has a screening hole. At the same time, isolation plates 10 are fixedly connected to the front and rear parts of the top of the working plate 6. When the compound fertilizer falls from the feed pipe 12, it will fall on the screening hole at the top of the working plate 6 and be blocked by the isolation plate 10 to prevent the compound fertilizer from shifting to other places during vibration. Then a pushing device is provided between the front and rear isolation plates 10. 11, at the same time, positioning holes 7 are opened on the front and rear parts of both sides of the top of the working plate 6. It should be emphasized that the two isolation plates 10 are between the front and rear positioning holes 7, and then positioning columns 8 are inserted into the positioning holes 7 on the front and rear parts of the two sides, and the bottom ends of the positioning columns 8 on both sides are fixedly connected to the receiving seat 3. Here, the separated sides of the receiving seats 3 on both sides are fixedly connected to the screening box 1. In addition, a spring 9 is wound around the periphery of the front and rear positioning columns 8 on both sides, and the top and bottom ends of the spring 9 are respectively fixedly connected to the working plate 6 and the receiving seat 3, and then a vibration device 5 is provided in the middle of the top of the receiving seat 3 on both sides. So far, The effect achieved is that when the vibration device 5 starts to run, the working plate 6 will continuously move up and down on the positioning column 8, and at the same time the working plate 6 will continuously compress and stretch the spring 9, and then the blocking plates 4 are fixedly connected to the adjacent sides of the receiving seats 3 on both sides. It should be noted that the height of the blocking plates 4 will not affect the vibration of the vibration device 5 on the working plate 6, and then the ramp plate 2 is fixedly connected to the bottom wall of the screening box 1, and then the discharge cylinder 13 is fixedly connected to the upper part of the side of the screening box 1 away from the pushing device 11. The discharge cylinder 13 is used in conjunction with the working plate 6, and the lower part of the screening box 1 away from the pushing device 11 is opened A discharge port 14 is provided, and a discharge plate 15 for use with the discharge port 14 is fixedly connected to one side of the screening box 1. The effect achieved here is that when the compound fertilizer falls from the feed pipe 12, it first reaches the screening hole in the middle of the working plate 6, and then the vibrating device 5 starts to vibrate. Through the vibration of the vibrating device 5, large compound fertilizer particles are retained on the working plate 6, while small compound fertilizer falls from the screening hole of the working plate 6, and then the compound fertilizer that falls on the ramp plate 2 is discharged to the outside of the screening box 1 through the discharge port 14 due to gravity. At the same time, the pushing device 11 pushes the residual compound fertilizer on the working plate 6 to the outside of the screening box 1 through the discharge cylinder 13.

[0036] The above-mentioned structures together constitute the general appearance structure of the screening device for compound fertilizer processing of the present invention.

[0037] In order to further explain the specific working principle of the screening device for compound fertilizer processing of the present invention, the above-mentioned pushing device 11 includes a through hole 1101 opened on the upper part of the side of the screening box 1 away from the discharge barrel 13. First, a connecting plate 1107 is provided above the working plate 6, and the bottom end of the connecting plate 1107 is fixedly connected to a silicone pad 1109, and the silicone pad 1109 is used in conjunction with the working plate 6. Then, a pushing plate 1108 is fixedly connected to the side of the top of the connecting plate 1107 close to the discharge barrel 13. The pushing plate 1108 is used to push the compound fertilizer on the working plate 6. At the same time, dampers 1110 are fixedly connected to the front and rear parts of the top of the connecting plate 1107 away from the push plate 1108. Then, the top of the damper 1110 is fixedly connected to the fixed plate 1105, and springs 110 are wound around the periphery of the front and rear dampers 1110. 1106, and the top and bottom ends of spring two 1106 are fixedly connected to the fixed plate 1105 and the connecting plate two 1107 respectively. The effect achieved here is that when the connecting plate two 1107 rises, the connecting plate two 1107 will compress the spring two 1106 and the damper 1110. In addition, a connecting plate one 1104 is fixedly connected to the side of the bottom end of the fixed plate 1105 away from the spring two 1106, and then a multi-stage electric push rod 1103 is fixedly connected to the front and rear parts of the connecting plate one 1104 away from the spring two 1106. The multi-stage electric push rod 1103 can push the connecting plate one 1104 to the specified position, and then a protective shell 1102 used in conjunction with the through hole one 1101 is fixedly connected to one side of the screening box 1. Finally, the two multi-stage electric push rods 1103 are fixedly connected to the side wall of the protective shell 1102 away from the side of the connecting plate one 1104.

[0038] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when it is necessary to push away the residual compound fertilizer on the working plate 6, the two multi-stage electric push rods 1103 push the connecting plate 1104 toward the side close to the discharge barrel 13, and then the connecting plate 1104 will drive the fixed plate 1105 fixedly connected to it to move together, and the fixed plate 1105 will indirectly drive the pushing plate 1108 to move together. In the process of moving the pushing plate 1108, the residual compound fertilizer on the working plate 6 will be pushed out of the screening box 1. At the same time, in this process, the connecting plate 2 1107 will also move up and down continuously. In the process of moving the connecting plate 2 1107, the spring 2 1106 and the damper 1110 will be compressed to ensure that the silicone pad 1109 on the connecting plate 2 1107 can fit with the working plate 6.

[0039] In order to further explain the specific working principle of the screening device for compound fertilizer processing of the utility model, the vibration device 5 includes a fixed shell 501 fixedly connected to the middle part of the top of the receiving seat 3, and an exciter 502 is arranged in the fixed shell 501. Through the fixed shell 501, not only can the exciter 502 be fixed, but also the exciter 502 can be protected from impact damage. Finally, a coupling block 503 is fixedly connected to the output shaft of the exciter 502, and the top of the coupling block 503 is fixedly connected to the working plate 6. It should be noted that the coupling block 503 has a certain elasticity, so as to reduce the damage of the exciter 502 to the working plate 6 when it is constantly vibrating.

[0040] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the working plate 6 needs to be vibrated, the working rod of the exciter 502 first continuously pushes the connecting block 503 to move up and down. When the connecting block 503 is displaced, it can drive the working plate 6 to move together, thereby completing the vibration of the working plate 6.
