Technical Field
[0001] This utility model relates to the field of screening device technology, specifically to a screening mechanism of a feed raw material crushing device. Background Technology
[0002] During feed production, after crushing, feed needs to be screened to separate particles of different diameters to meet the different needs of subsequent processing. However, many existing feed screening methods use screens, which are prone to clogging after prolonged use, thus affecting the screening efficiency. Utility Model Content
[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a screening mechanism for a feed raw material crushing device, which has the advantages of avoiding clogging during feed screening.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a screening mechanism for a feed raw material crushing device, comprising:
[0005] frame;
[0006] The partition is horizontally installed inside the frame and has a discharge port.
[0007] Screening roller, the screening roller is set above the partition plate;
[0008] The adjustable material hopper is located below the discharge port;
[0009] The screening roller includes a fixed roller and an adjusting roller arranged in parallel, and the adjusting roller is connected to a telescopic cylinder set on the inner wall of the frame.
[0010] Preferably, the regulating hopper includes:
[0011] A rotating shaft is located below the discharge port;
[0012] The trapezoidal material bucket is a hollow isosceles trapezoidal structure. The rotating shaft passes through the trapezoidal material bucket, which is rotatably positioned below the discharge port via the rotating shaft. Both the upper and lower bottom edges of the trapezoidal material bucket are open.
[0013] The feed guide block is installed inside the top bottom opening of the trapezoidal feed hopper via multiple return springs. By rotating the trapezoidal feed hopper, the feed guide block is rotated to the upper or lower position, thereby guiding the feed after it is discharged from the outlet or screening and collecting the feed through the trapezoidal feed hopper.
[0014] Preferably, the cross-section of the guide block is an isosceles triangle, and the bottom surface of the guide block and the upper bottom edge opening of the trapezoidal feed hopper are both rectangular structures. The bottom surface of the guide block is movably installed through the upper bottom edge opening of the trapezoidal feed hopper by multiple return springs. When the trapezoidal feed hopper is rotated so that the guide block is located in the discharge port, the screened feed can slide down along both sides of the guide block to the bottom surface inside the frame under the action of the guide block, which is convenient for collection.
[0015] Preferably, the opening at the bottom edge of the trapezoidal feed hopper corresponds to the position of the discharge port, which facilitates rotating the guide block to the lower position by rotating the trapezoidal feed hopper, so that the feed screened by the fixed roller and the adjusting roller can be collected through the trapezoidal feed hopper.
[0016] Preferably, the fixed roller comprises:
[0017] The fixed roller motor is embedded in the inner wall of the frame;
[0018] The rolling shaft is coaxially and fixedly sleeved outside the output shaft of the fixed roller motor, and the outer peripheral wall of the rolling shaft has a sawtooth structure.
[0019] Separating disc 1, there are multiple separating discs 1. Separating disc 1 is fixedly sleeved on the outside of the crushing shaft, and multiple separating disc 1 are distributed at intervals along the length of the axis of the crushing shaft. The fixed roller motor drives the crushing shaft and separating disc 1 to rotate simultaneously. With the cooperation of the crushing shaft and separating disc 2, the feed can be screened and discharged through the gap between separating disc 2 and the crushing shaft.
[0020] Preferably, the adjusting roller comprises:
[0021] The U-shaped roller frame is mounted on the piston rod of the telescopic cylinder, and the U-shaped opening of the U-shaped roller frame faces the direction of the rolling axis.
[0022] The adjusting roller motor is embedded in the inner wall of the U-shaped opening of the U-shaped roller frame, and the rotation direction of the adjusting roller motor is opposite to that of the fixed roller motor.
[0023] Separating disc two, there are multiple separating discs two. Separating disc two is fixedly sleeved outside the output shaft of the adjusting roller motor, and separating disc two is distributed at intervals with separating disc one. The outer peripheral wall of separating disc two has a sawtooth structure. The fixed roller motor drives the grinding shaft and separating disc one to rotate at the same time. With the cooperation of the grinding shaft and separating disc two, the feed can be screened and discharged through the gap between separating disc two and grinding shaft.
[0024] Preferably, the number of the second separators is less than the number of the first separators, and each second separator is located between two first separators at corresponding positions. With the cooperation of the crushing shaft and the second separators, the feed can be screened and discharged through the gap between the second separator and the crushing shaft.
[0025] Preferably, the size of the discharge port is adapted to the size of the bottom opening of the trapezoidal feed hopper, so that the feed can be collected through the discharge port and the bottom opening of the trapezoidal feed hopper.
[0026] Preferably, the outer peripheral wall of the second separator plate and the outer peripheral wall of the grinding shaft are spaced apart, which facilitates the screening and feeding of feed through the gap between the second separator plate and the grinding shaft.
[0027] Preferably, the top of the frame is provided with a feeding port, and the overlapping position between the second separator and the first separator corresponds to the position of the feeding port, so that the feed added through the feeding port can fall to the position between the second separator and the crushing shaft, which is convenient for screening.
[0028] The beneficial effects of this utility model are as follows: 1. Feed can be screened by fixed rollers and adjusting rollers arranged in parallel, and the position of the adjusting hopper can be adjusted by rotating to collect or guide feed particles of different diameters after screening.
[0029] 2. The feed with smaller particle diameter can be screened and collected between the grinding shaft and the second separator plate first. Then, the telescopic cylinder is activated to drive the U-shaped roller frame and the second separator plate to move away from the fixed roller motor. Then, the feed with larger particle diameter can be screened and collected between the grinding shaft and the second separator plate. This can achieve the screening of feed particles of different diameters without the phenomenon of feed blockage. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Example 1
[0040] like Figures 1 to 6 As shown, this utility model provides a screening mechanism for a feed raw material crushing device, including a frame 1; a partition 2 horizontally arranged inside the frame 1, with a discharge port 21 on the partition 2; a screening roller 3 arranged above the partition 2; and an adjusting hopper 4 rotatably arranged below the discharge port 21. The screening roller 3 includes a fixed roller 31 and an adjusting roller 32 arranged side by side, and the adjusting roller 32 is connected to a telescopic cylinder 33 arranged on the inner wall of the frame 1. Feed is added between the fixed roller 31 and the adjusting roller 32, and is screened under the action of the fixed roller 31 and the adjusting roller 32. The screened feed falls into the adjusting hopper 4 through the discharge port 21 on the partition 2 for collection.
[0041] The position of the adjusting roller 32 can also be adjusted under the action of the telescopic cylinder 33. The telescopic cylinder 33 extends and retracts, driving the adjusting roller 32 to adjust the distance between it and the fixed roller 31 (that is, adjusting the distance between the fixed roller 31 and the adjusting roller 32), thereby enabling the feed to achieve different screening effects.
[0042] Example 2
[0043] Based on Example 1, such as Figure 2 , Figures 4 to 6 As shown, the adjusting material bucket 4 includes a rotating shaft 41, which is located below the discharge port 21; the trapezoidal material bucket 42 is a hollow isosceles trapezoidal structure, with the rotating shaft 41 passing through it, and the trapezoidal material bucket 42 is rotatably positioned below the discharge port 21 via the rotating shaft 41, and both the upper and lower bottom edges of the trapezoidal material bucket 42 are open; the guide block 43 is movably positioned through the upper bottom edge opening of the trapezoidal material bucket 42 via multiple return springs 44; the cross-section of the guide block 43 is an isosceles triangle, and both the bottom surface of the guide block 43 and the upper bottom edge opening of the trapezoidal material bucket 42 are rectangular structures, with the bottom surface of the guide block 43 movably positioned through the upper bottom edge opening of the trapezoidal material bucket 42 via multiple return springs 44; the opening of the lower bottom edge of the trapezoidal material bucket 42 corresponds to the position of the discharge port 21.
[0044] When feed collection is required, the trapezoidal feed hopper 42 can be rotated so that the bottom opening of the trapezoidal feed hopper 42 faces the fixed roller 31 and the adjusting roller 32. After the feed falls between the fixed roller 31 and the adjusting roller 32, since the size of the discharge port 21 is adapted to the size of the bottom opening of the trapezoidal feed hopper 42, the feed can enter the trapezoidal feed hopper 42 through the discharge port 21 on the partition 2 for collection. (And when the weight of the feed in the trapezoidal feed hopper 42 is greater than the tension of the return spring 44, the guide block 43 can be pushed away from the top opening of the trapezoidal feed hopper 42.) This allows the feed to be discharged from the top bottom opening of the trapezoidal feed hopper 42. When the weight of the feed in the trapezoidal feed hopper 42 is less than the tension of the return spring 44, the feed can be kept inside the trapezoidal feed hopper 42. When it is not necessary to collect the feed, the trapezoidal feed hopper 42 can be rotated so that the guide block 43 faces the direction of the fixed roller 31 and the adjusting roller 32. After the feed falls between the fixed roller 31 and the adjusting roller 32, it can fall onto the guide block 43 and then slide down the two side walls of the guide block 43 to the two sides of the frame 1, thereby realizing feed diversion and avoiding the accumulation of feed after screening.
[0045] A rotating motor can also be embedded inside the frame 1, with the rotating shaft 41 coaxially mounted on the output shaft of the rotating motor, so that the rotating motor can drive the trapezoidal material bucket 42 to rotate for position adjustment.
[0046] Example 3
[0047] Based on Example 1, such as Figures 1 to 3As shown, the fixed roller 31 includes a fixed roller motor 311, which is embedded in the inner wall of the frame 1; the rolling shaft 312 is coaxially fixedly sleeved outside the output shaft of the fixed roller motor 311, and the outer peripheral wall of the rolling shaft 312 has a sawtooth structure; multiple partition discs 313 are provided, which are fixedly sleeved outside the rolling shaft 312, and the multiple partition discs 313 are spaced apart along the length of the axis of the rolling shaft 312; the adjusting roller 32 includes a U-shaped roller frame 321, which is set on the piston rod of the telescopic cylinder 33, and the U-shaped opening of the U-shaped roller frame 321 faces the rolling shaft 312; the adjusting roller motor 322 is embedded in the U-shaped opening of the U-shaped roller frame 321. On the inner wall of the opening, the rotation direction of the adjusting roller motor 322 is opposite to that of the fixed roller motor 311; multiple partition discs 323 are provided, which are fixedly sleeved on the outside of the output shaft of the adjusting roller motor 322, and are distributed alternately with partition discs 313. The outer peripheral wall of partition discs 323 has a serrated structure; the number of partition discs 323 is less than the number of partition discs 313, and each partition disc 323 is located between two partition discs 313 in the corresponding position; the outer peripheral wall of partition discs 323 is distributed alternately with the outer peripheral wall of the grinding shaft 312, which facilitates the screening and feeding of feed through the gap between partition discs 323 and grinding shaft 312.
[0048] According to the screening needs, the telescopic cylinder 33 can be activated to drive the U-shaped roller frame 321 and the second separator 323 to move simultaneously towards or away from the fixed roller motor 311, thereby adjusting the distance between the crushing shaft 312 and the second separator 323. This facilitates the screening and feeding of feed of different particle sizes between the crushing shaft 312 and the second separator 323. Specifically, after the feed is added to the position between the crushing shaft 312 and the second separator 323, the fixed roller motor 311 drives the crushing shaft 312 and the first separator 313 to rotate, while the adjusting roller motor 322 drives the second separator 323 to rotate, thus allowing the feed to pass between the crushing shaft 312 and the second separator 323. The feed is fed at the designated position (the outer peripheral walls of the crushing shaft 312 and the second separator 323 are both serrated to prevent the feed from accumulating between the crushing shaft 312 and the second separator 323, allowing for crushing and preventing accumulation or blockage); at the same time, smaller diameter feed particles can be screened and collected between the crushing shaft 312 and the second separator 323 first, and then the telescopic cylinder 33 is activated to drive the U-shaped roller frame 321 and the second separator 323 to move away from the fixed roller motor 311, allowing larger diameter feed particles to be screened and collected between the crushing shaft 312 and the second separator 323, thus achieving the screening of feed particles of different diameters.
[0049] Example 4
[0050] Based on Example 1, such as Figures 1 to 3 As shown, the top of the frame 1 is provided with a feeding port 11, and the overlapping position between the second separator 323 and the first separator 313 corresponds to the position of the feeding port 11; so that after the feed is added through the feeding port 11, it can fall to the position between the second separator 323 and the crushing shaft 312, which is convenient for screening.
[0051] A feeding pipe can also be vertically installed inside the feeding port 11. Multiple slots adapted to the first separating disc 313 and the second separating disc 323 are respectively provided on the opposite side walls at the lower end of the feeding pipe. This allows the second separating disc 313 and the second separating disc 323 to be inserted into their corresponding slots when the lower end of the feeding pipe contacts them. This facilitates the feeding of feed from the feeding port 11, allowing it to pass through the feeding pipe and be screened between the first separating disc 313 and the second separating disc 323. Feed that cannot pass through the first separating disc 313 and the second separating disc 323 can be screened. The feed between 323 can remain between the first separator 313 and the second separator 323. After screening is completed and the feed collected in the trapezoidal feed hopper 42 is cleaned, the trapezoidal feed hopper 42 is rotated so that the bottom opening of the trapezoidal feed hopper 42 faces between the first separator 313 and the second separator 323. The telescopic cylinder 33 is activated to drive the U-shaped roller frame 321 and the second separator 323 to move away from the fixed roller motor 311 at the same time. At this time, the feed that cannot pass between the first separator 313 and the second separator 323 can fall into the trapezoidal feed hopper 42 for collection.
[0052] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
