[0026] The first aspect of the utility model, as shown in Figure 1 , Figure 2 and Figure 3 , the scheme is a screening process added in the normal transportation process of chemical fertilizer, preferably adding this screening function in the transportation process of the last bagging of chemical fertilizer.
[0027] Specifically, first, the conveyor belt 102 is set as a net-shaped conveyor belt 102, and the mesh aperture on the conveyor belt 102 is smaller than the diameter of the chemical fertilizer particles, wherein the conveyor belt 102 is rotationally connected to the conveying table 101, and the conveying table 101 is the original conveying equipment for transferring chemical fertilizer particles.
[0028] In addition, a supporting plate 105 is arranged inside the conveyor belt 102, the supporting plate 105 is located at the bottom of the inside of the conveyor belt 102, and the lower end surface of the supporting plate 105 is slidingly connected with the conveyor belt 102. The supporting plate 105 is also located between two driving rollers 104 for driving the conveyor belt 102 to rotate, and the supporting plate 105 is fixedly connected with the conveying table 101. The driving roller 104 is rotationally connected to the conveying table 101 and fixedly connected with the output shaft of the driving motor on the conveying table 101, and the driving roller 104 is rotationally connected with the supporting plate 105.
[0029] The key point is that, as shown in Figure 2 and Figure 3As shown, a screening area is arranged in the middle of the conveying belt 102, and a plurality of air cylinders 107 are arranged in the screening area, and a top plate 108 is connected to the output shaft of the air cylinder 107, and the top plate 108 is used to impact the conveying belt 102 above, and the top plate 108 can make the plastic plate, and a layer of sponge or rubber pad is arranged at the upper end.
[0030] In the screening area, the fertilizer particles are screened, and the fertilizer is transported while being screened, and the production efficiency is not affected, and the quality of the product finally bagged is ensured.
[0031] Preferably, the air cylinder 107 is arranged in three, and the air cylinder 107 is fixedly connected to the upper end surface of the supporting plate 105, and the air cylinder 107 periodically impacts the conveying belt 102, so that the broken particles and dry powder can be smoothly screened out, and the screening effect is ensured.
[0032] In another aspect, as shown in Figure 3 and Figure 4 As shown, the conveying table 101 is further provided with a plurality of air suction ports 109 in communication with the inner space of the conveying belt 102, and each air suction port 109 is connected to an external air suction pump through an air suction pipe 110 fixedly connected to the conveying table 101.
[0033] The two ends of the screening area are each provided with a partition plate 106 fixedly connected to the supporting plate 105, and the upper end surface of the partition plate 106 is in sliding connection with the conveying belt 102, and all the air suction ports 109 are located in the screening area between the two partition plates 106.
[0034] The broken particles and dry powder screened out are sucked away for recycling, and the remaining complete particle fertilizer is smoothly sent to the next process. The whole process does not need to stop the transportation of the fertilizer, and the production efficiency is ensured.
[0035] In particular, a splash-proof cover 103 is further arranged above the conveying belt 102, and the lower end of the splash-proof cover 103 is fixedly connected to the conveying table 101, and the screening area is located within the range below the splash-proof cover 103.
[0036] When the air cylinder 107 periodically impacts the conveying belt 102, the fertilizer particles above the conveying belt 102 will be splashed out of the conveying belt 102 due to the impact, and finally be conveyed to the next process by the conveying belt 102, and it is ensured that the fertilizer reaching the next process is in the form of particles, and the broken particles and dry powder are screened out. DETAILED DESCRIPTION
[0037] After the fertilizer is produced, before being bagged, the fertilizer is first transported to the inlet end of the conveying table 101, and finally bagged from the outlet end of the conveying table 101.
[0038] In the process, the fertilizer will pass through the screening area below the splash guard 103, the three air cylinders 107 in the screening area continuously drive the top plate 108 to hit the conveying belt 102 above, so that the conveying belt 102 in this area is continuously vibrated, and the fertilizer particles in this area are also continuously thrown down. However, the fertilizer particles cannot splash out of the conveying belt 102 due to the shielding of the splash guard 103. The continuous throwing down of the fertilizer particles makes the dry powder and the broken particles pass through the mesh holes of the mesh conveying belt 102 and fall into the conveying belt 102, that is, fall into the screening area between the two partitions 106. The conveying table 101 is also provided with a plurality of air suction ports 109 in communication with the inside space of the conveying belt 102, and each air suction port 109 is connected with an external air suction pump through an air suction pipe 110 fixedly connected to the conveying table 101.
[0039] Therefore, the broken particles and the dry powder screened out are sucked away for recycling, and the remaining complete particle fertilizer, because its diameter is greater than the mesh hole diameter of the conveying belt 102, cannot fall into the conveying belt 102, but can smoothly enter the next process. The whole process does not need to stop the transportation of the fertilizer, ensuring the production efficiency. While not affecting the production efficiency, the quality of the finally bagged product is ensured.
[0040] Based on the above, the utility model discloses a screening area in the conveying belt 102, and the fertilizer particles are screened in the screening area. The fertilizer is screened while being transported, the production efficiency is not affected, and the quality of the finally bagged product is ensured. The mesh conveying belt 102 is adopted, and the mesh hole diameter of the mesh conveying belt 102 is less than the diameter of the fertilizer particles. The air cylinder 107 is arranged in the screening area to periodically hit the conveying belt 102, so that the broken particles and the dry powder can be smoothly screened out, and the screening effect is ensured. The broken particles and the dry powder screened out are sucked away for recycling, and the remaining complete particle fertilizer can smoothly enter the next process. The whole process does not need to stop the transportation of the fertilizer, ensuring the production efficiency.
