DETAILED DESCRIPTION

[0031] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] The present invention provides a pulverizing device for mixed feed, see Figure 1 , Figure 2 and Figure 5 The invention comprises a base 1 and a crushing cylinder 2 fixedly connected to the upper end of the base 1. A crushing cone 3 is arranged inside the crushing cylinder 2. Figure 6 As shown, the inside of the base 1 is fixedly connected with a motor 301, and the output end of the motor 301 movably passes through the base 1 and the bottom end of the crushing tube 2 until it is fixedly connected with the lower end of the crushing cone 3, and the outer side of the crushing cone 3 is sleeved with a crushing disk 1 41, a crushing disk 2 42 and a crushing disk 3 43 which are distributed in sequence from top to bottom;

[0034] See also Figure 3 and Figure 4 The crushing disc 1 41, the crushing disc 2 42 and the crushing disc 3 43 have the same structure and all include an inclined mesh disc 401, a crushing ring 402, a connecting rod 403 and an outer ring 404. The inclined mesh disc 401 is fixedly connected to the upper end of the crushing ring 402, the outer ring 404 is sleeved on the outer side of the crushing ring 402, and a plurality of connecting rods 403 are provided and are evenly fixedly connected between the crushing ring 402 and the outer ring 404. Figure 5 and Figure 6 The inclined mesh plate 401 and the crushing ring 402 are located inside the crushing cylinder 2, the outer ring 404 is located outside the crushing cylinder 2, and a plurality of evenly distributed strip holes 201 are opened at the side end of the crushing cylinder 2, and a plurality of connecting rods 403 are slidably connected to the inside of the plurality of strip holes 201 respectively.

[0035] See also Figure 5A pair of cylinders 1 51, a pair of cylinders 2 52 and a pair of cylinders 3 53 are fixedly connected to the upper end of the base 1, the telescopic end of the cylinder 3 53 is fixedly connected to the lowermost outer ring 404, the telescopic end of the cylinder 2 52 movably penetrates the lowermost outer ring 404 and is fixedly connected to the outer ring 404 at the middle position, the telescopic end of the cylinder 1 51 movably penetrates the pair of outer rings 404 from bottom to top in sequence until it is fixedly connected to the uppermost outer ring 404, that is, the cylinder 1 51 drives the entire crushing disk 1 41 to move up and down, the cylinder 2 52 drives the entire crushing disk 2 42 to move up and down, and the cylinder 3 53 drives the entire crushing disk 3 43 to move up and down, so as to adjust the crushing distance between the multiple crushing rings 402 and the crushing cone 3, so as to facilitate the graded crushing of materials of different sizes.

[0036] The crushing cone 3 is a truncated cone structure that is thin at the top and thick at the bottom. The inner end face of the crushing ring 402 is a conical surface structure that matches the outer end face of the crushing cone 3, and the inner diameters of the multiple crushing rings 402 gradually increase from top to bottom. After adjusting the position of each crushing ring 402 up and down, it is convenient to make the spacing between the multiple crushing rings 402 and the crushing cone 3 gradually decrease from top to bottom. The process of crushing large particles of feed first and then finely crushing small particles of feed is realized.

[0037] The inclined mesh plate 401 has a conical structure and is inclined downward in a direction close to the crushing cone 3. The mesh apertures of the multiple inclined mesh plates 401 gradually decrease from top to bottom. The conical structure of the inclined mesh plates 401 facilitates the feed to roll toward the crushing cone 3 and enter between the crushing ring 402 and the crushing cone 3 for crushing. At the same time, during the rolling process of the feed, small particles of feed can be directly transferred to the next inclined mesh plate 401 through the mesh of the crushing ring 402, so as to achieve simultaneous feed screening and crushing. In addition, through the screening process, feed particles with too large size differences are not crushed in the same way, which can effectively improve the adequacy of feed crushing. The size of the crushed material obtained between the previous crushing ring 402 and the crushing cone 3 is similar to the size of the feed particles directly falling on the next inclined mesh plate 401. Then the two enter between the next crushing ring 402 and the crushing cone 3 for further crushing, and finally a feed product with the required crushing requirements can be obtained.

[0038] The upper end of the crushing cylinder 2 is fixedly connected with a feed pipe communicating therewith, and the side end of the crushing cylinder 2 is fixedly connected with a discharge pipe 8, and the crushed feed can be sucked out through the discharge pipe 8 by a suction machine.

[0039] A pulverizing device for mixed feed, the use method of which comprises the following steps:

[0040] S1, such as Figure 7As shown, according to the material crushing requirements, the cylinder 1 51, the cylinder 2 52 and the cylinder 3 53 are started to drive the crushing disc 1 41, the crushing disc 2 42 and the crushing disc 3 43 to move up and down respectively, and the distances between the multiple crushing rings 402 and the crushing cone 3 are adjusted. It is assumed that the distances between the multiple crushing rings 402 and the crushing cone 3 from top to bottom are Q1, Q2 and Q3 respectively, then Q1>Q2>Q3, so that the feed can be crushed step by step from coarse to fine;

[0041] S2, such as Figure 8 As shown, the motor 301 is started to drive the crushing cone 3 to rotate, and a crushing channel is formed between the rotating crushing cone 3 and the crushing ring 402. The material to be processed is fed into the crushing cylinder 2 through the feed pipe, and the material rolls along the conical table 71, and finally falls along the four sides of the conical table 71 to the uppermost inclined mesh plate 401;

[0042] S3, the material rolls along the inclined surface of the inclined mesh plate 401 toward the crushing cone 3, wherein: the larger material particles directly roll down to the gap between the crushing ring 402 and the crushing cone 3 for crushing, and the crushed material falls between the next crushing ring 402 and the crushing cone 3 for further crushing; the smaller material particles directly pass through the mesh of the inclined mesh plate 401 and fall onto the inclined mesh plate 401 on the lower side, and then also roll along the inclined surface of the inclined mesh plate 401 for screening and crushing;

[0043] S4. After the materials are separated and subjected to synchronous screening and crushing processes, all the materials finally enter between the lowermost crushing ring 402 and the crushing cone 3 for crushing to obtain crushed materials that meet the requirements.

[0044] The present application arranges a plurality of inclined mesh plates 401 with mesh apertures distributed in stages, and adjusts the crushing distance between each crushing ring 402 and the crushing cone 3 as needed. During use, the size separation process of the mixed feed and the crushing process from coarse to fine are simultaneously realized. On the basis of effectively avoiding the crushing of feeds with too large size differences in one step, the full crushing process of the mixed feed mixed with particles of different sizes is realized, and feed crushed particles of the required size standard can be obtained, which greatly improves the applicability of the present application and has high practical and economic value.

[0045] Second implementation method:

[0046] Based on the embodiment 1, the present embodiment adds a blanking assembly table and a material shielding sleeve 6, specifically as follows: a blanking assembly table is also provided inside the pulverizing cylinder 2, and the blanking assembly table includes a conical table 71, and the conical table 71 is fixedly connected to the upper end of the pulverizing cone 3, and the upper end surface of the conical table 71 is a downwardly inclined conical surface, and the blanking assembly table also includes a circular ring 72 arranged on the outside of the conical table 71, and the circular ring 72 is fixedly connected to the inner wall of the pulverizing cylinder 2, and there is a gap between the conical table 71 and the circular ring 72 in the horizontal direction.

[0047] By setting the conical table 71, the feed to be processed can be dispersed and fall to the edge of the inclined mesh plate 401, and then roll and screen along the inclined mesh plate 401. In addition, the conical table 71 rotates with the crushing cone 3. On the one hand, the feed can be quickly dispersed and not easily accumulated on the upper end of the conical table 71. On the other hand, the feed is thrown outward by centrifugal force, so that part of the feed can hit the inner wall of the crushing cylinder 2 and break, effectively reducing the content of large particles of feed. The inner diameter of the ring 72 is smaller than the outer diameter of the inclined mesh plate 401, so that the feed passing between the conical table 71 and the ring 72 can fully fall onto the inclined mesh plate 401 below it.

[0048] A material shielding sleeve 6 is fixedly connected between the circular ring 72 and the uppermost connecting rod 403, between the lowermost connecting rod 403 and the inner bottom surface of the crushing barrel 2, and between adjacent connecting rods 403. The material shielding sleeve 6 is in a relaxed state in the vertical direction. The inclined mesh plate 401 is located on the inner side of the material shielding sleeve 6. The discharge pipe 8 is fixedly passed through the lowermost material shielding sleeve 6 and communicated with the inner side thereof. The arrangement of the material shielding sleeve 6 can effectively shield the strip hole 201, so that the material in the crushing process is not easily dropped to the outside through the strip hole 201 without affecting the crushing process.

[0049] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
