Description

Technical Field

[0001] The utility model relates to the technical field of granular material processing, and particularly relates to a material sorting device. Background Technique

[0002] In the production process of fertilizers, screening is a key step, and its main purpose is to ensure the uniformity and appropriate size of fertilizer particles. Uniform particle size is crucial for the effective application of fertilizers because it directly affects the fluidity of fertilizers, the uniformity of application, and the crop absorption efficiency. Therefore, effective screening technology is of great significance for ensuring fertilizer quality and improving agricultural production efficiency.

[0003] The publication number CN211488462U discloses a chemical fertilizer particle screening device. By arranging a blocking component in the screening barrel, the blocking component can intercept the chemical fertilizer particles rolling in the screening barrel, so that part of the chemical fertilizer particles flow back for secondary screening, effectively improving the screening effect. However, in the above scheme, the aperture of the screen mesh is the same, and it can only screen chemical fertilizer particles of the same particle size, with a small application range and unable to meet the production requirements of screening chemical fertilizers of different particle sizes.

[0004] Therefore, we propose a material sorting device to solve the problems raised above. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0024] Please refer to Figures 1-3 As shown, the present utility model provides a material sorting device, including a screening cylinder 1. The left and right ends of the screening cylinder 1 are respectively a feeding end and a discharging end. A blanking mechanism 4 is arranged at the discharging end. A plurality of screening holes 11 with gradually increasing apertures from left to right are formed on the screening cylinder 1. A spiral pushing piece 12 is arranged on the inner wall of the screening cylinder 1 from left to right. A material receiving mechanism 2 is arranged below the screening cylinder 1;

[0025] The material receiving mechanism 2 includes a material receiving box 21 with an open top and partitions 22 fixedly arranged at intervals in the material receiving box 21. The partitions 22 divide the material receiving box 21 into a plurality of branch material receiving boxes 23. The screening cylinder 1 is rotatably connected to the tops of the plurality of partitions 22.

[0026] The blanking mechanism 4 includes a temporary storage bin 41. A guiding box 42 in an inverted funnel shape is arranged at the bottom of the temporary storage bin 41. An outlet pipe 43 is arranged at the bottom of the guiding box 42. An electromagnetic valve 44 is arranged on the outlet pipe 43. A conical cylinder 13 communicated with the outlet pipe 43 is arranged at the feeding end of the screening cylinder 1.

[0027] A driving mechanism 3 is arranged on one side of the screening cylinder 1 and the material receiving box 21. The driving mechanism 3 includes a driving motor 31. A transmission gear 32 is arranged on the rotating shaft of the driving motor 31. A toothed ring 33 meshing with the transmission gear 32 is arranged on the screening cylinder 1.

[0028] When the electromagnetic valve 44 is opened, the material enters the feeding end of the screening cylinder 1 from the temporary storage bin 41 through the outlet pipe 43 and the conical cylinder 13. The driving mechanism 3 drives the screening cylinder 1 to rotate. When the screening cylinder 1 rotates, under the action of the spiral pushing piece 12, the material moves towards the discharging end. Since the screening holes 11 with gradually increasing apertures from left to right are formed on the side wall of the screening cylinder 1, when passing through the screening holes 11 with different diameters, the material particles with corresponding particle sizes will fall into the corresponding branch material receiving boxes 23. The sorting operation of materials with different particle sizes can be completed in one pass, with a wide application range and time saved for multiple sorting operations.

[0029] As a preferred technical solution of the present utility model: One side of the branch material receiving box 23 is a material taking port. A closing plate 24 is hinged on one side of the material taking port. A fixed lock is arranged between the closing plate 24 and the side wall of the partition plate 22. A diversion plate 25 is arranged at the bottom of the branch material receiving box 23. One end of the diversion plate 25 close to the material taking port is inclined downward. The arrangement of the material taking port facilitates taking the material in the branch material receiving box 23. The closing plate 24 is in a closed state under normal conditions and can be opened during material taking to prevent the material from flowing out from the material taking port during sorting; the arrangement of the diversion plate 25 enables the material to flow towards the material taking port, facilitating material taking.

[0030] For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances; for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
