Description

Technical Field

[0001] The utility model belongs to the technical field of material sorting, in particular to a raw material sorting device for production. Background Art

[0002] Production materials are the most important foundation for production and manufacturing activities, and production materials need to be processed more finely before they are actually put into production and use, which includes sorting operations. Sorting equipment is used to sort production materials and classify materials according to their certain characteristics. The most common of the above characteristics is particle diameter. Different types of materials are sorted according to their different particle diameters, and the most suitable materials for production operations are taken out. The remaining materials are further processed in a finer manner. Sorting devices are mainly divided into two types according to their screening methods: air blast screening and vibration screening. Air blast screening is mainly used for sorting light materials, while vibration screening is used for sorting heavier materials.

[0003] A Chinese patent application (or patent) with publication number CN219253279U discloses a vibrating screen for sorting raw materials for mining, comprising a housing, the inner wall of which is rotatably connected to a rotating barrel, a motor 1 fixedly connected to the front of the housing, an output shaft of the motor 1 passing through the housing and fixedly connected to the rotating barrel, three grooves being provided on the outer side of the rotating barrel, a sliding rod slidably connected thereto interspersed with the inner walls of the three grooves, the three sliding rods being square in shape, a sieve plate fixedly connected to one end of the three sliding rods away from the rotating barrel, springs fixedly connected between adjacent sieve plates and the grooves, an eccentric wheel rotatably connected to the inner wall of the rotating barrel, and a motor 2 fixedly connected to the back of the rotating barrel. This utility model can replace sieve plates of different apertures without disassembling the sieve plates, thus omitting the step of disassembling the sieve plates and effectively improving the efficiency of sieve plate replacement.

[0004] The above-mentioned mining raw material sorting vibrating screen has three sieve plates with different apertures in its box body, and the materials falling into the box body are screened by the sieve plates, and only one of the three sieve plates can perform screening work at a time. Therefore, when the actual screening work is carried out, after the required target particle diameter passes through the sieve plate and falls below, the material that does not meet the particle size diameter is retained above the sieve plate. The bottom of the chamber where the material is retained is horizontal, and there is no material pushing structure, so it will cause this part of the material to be difficult to flow out of the retained chamber, and continuous feeding will cause the material to block the chamber above the sieve plate; and, of the three sieve plates in its box body, only one and only one sieve plate can perform screening work at a time, so the target material screened out has only one particle size specification, and it is impossible to screen multiple groups of particle size specifications according to actual needs. To this end, we provide a raw material sorting device for production to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment 1

[0031] See also Figure 1-4 The utility model is a raw material sorting device for production, including a sorting box 1 and a sorting component 4 inserted in the sorting box 1. The sorting component 4 is composed of a primary sorting piece 401, a secondary sorting piece 402 and a tertiary sorting piece 403. The material entering the sorting box 1 is sorted by utilizing three groups of sorting pieces stacked relatively one above the other, and the apertures of the sorting holes on the three groups of sorting pieces decrease from top to bottom, and the aperture of the sorting holes on each sorting piece is adjustable.

[0032] Specifically, the top cover of the sorting box 1 is provided with a cover plate 2, and the feed trough 201 in the cover plate 2 is installed with a device for auxiliary materials to enter the feed hopper 3, and the right and left sides of the sorting box 1 are provided with inclined chutes 101, and the chutes 101 are respectively connected to the first-level sorting component 401, the second-level sorting component 402 and the third-level sorting component 403 in the sorting component 4. The structures of the first-level sorting component 401, the second-level sorting component 402 and the third-level sorting component 403 are the same, but the apertures of the sorting holes on the first-level sorting component 401, the second-level sorting component 402 and the third-level sorting component 403 decrease successively.

[0033] Furthermore, taking the three-stage sorting component 403 as an example, the three-stage sorting component 403 includes a sorting frame 403a, and a sorting slot 403a-1 inside it for inserting the sorting plate 403b, and the sorting frame 403a and the sorting plate 403b are both provided with plate holes 403b-1 with the same aperture, and one side outer wall of the sorting plate 403b is abutted against the spring 403d arranged on the inner wall of the sorting slot 403a-1 through the abutment plate 403c, and the sorting plate 403d is provided with side holes 403b-2 for inserting the positioning pin 403e in the front and rear side walls outside the sorting frame 403a.

[0034] The operation process of this embodiment is as follows: the material to be sorted is poured into the feed hopper 3, and the material falls into the interior of the sorting 1 under the action of its own gravity, firstly contacts the primary sorting element 401 in the sorting assembly 4, and the material that meets the aperture passes through the primary sorting element 401 and falls onto the secondary sorting element 402, and then the material that meets the aperture passes through the secondary sorting element 402 and falls onto the tertiary sorting element 403, and because the primary sorting element 401, the secondary sorting element 402 and the The three-stage sorting components 403 are all arranged in an inclined structure, so the materials retained on them roll toward the position of the lowest recovery trough 102. When it is necessary to adjust the screening aperture of the sorting component 4, it is only necessary to pull out the positioning pin 403e, and then pull the sorting plate 403b to change the overlap between the upper plate hole 403b-1 of the sorting plate 403b and the upper plate hole 403b-1 of the sorting frame 403a. After adjustment, the positioning pin 403e can be inserted into the side hole 403b-2 again. Specific embodiment 2

[0038] Furthermore, a card slot 501 a for being connected to the card plate 502 is provided on the inner wall at the end of the recovery box 501 , and a slide groove 502 a for assisting the folding plate 503 in folding and sliding is also provided in the card plate 502 .

[0039] The operation process of this embodiment is as follows: the screw rod 504a can be driven to work by the servo motor 504, and when the screw rod 504a is working, the folding plate 503 connected to it at its end through the driving nut will slide in the slide groove 502a, and when the servo motor 504 rotates forward, the folding plate 503 extends along the slide groove 502a to achieve the effect of closing the feeding port of the recovery box 501, and vice versa, the feeding port is opened. When the feeding port of the recovery box 501 is opened, the material retained on the corresponding sorting component in the sorting box 1 will flow into the recovery box 501 through the recovery trough 102 for storage.
