Description

Technical Field

[0001] The invention relates to the technical field of pet food processing, in particular to a bone crusher for pet food processing. Background Art

[0002] Bone crusher for pet food processing, also known as bone crusher or bone grinder, has the core function of crushing hard animal bones into smaller particles or powder for subsequent processing into pet food. This equipment plays an important role in the field of pet food manufacturing, not only improving production efficiency, but also ensuring the quality and nutritional value of pet food.

[0003] As disclosed in the publication number CN112604754A, the invention relates to a crusher, and in particular to a bone crusher for processing pet food. The technical problem to be solved by the invention is how to design a bone crusher for processing pet food that can save manpower during operation and can perform multiple crushing to achieve a better crushing effect. In order to solve the above technical problems, the invention provides a bone crusher for processing pet food, comprising: a frame, one side of the top of which is connected to a support frame; a discharge box, which is connected to the support frame, and one side of the top of the discharge box is connected to a discharge hopper, and the discharge hopper is connected to the inside of the discharge box; a preliminary crushing mechanism, which is arranged on the discharge box; a discharge mechanism, which is arranged between the preliminary crushing mechanism and the discharge box. The invention achieves the effect of crushing the bones by cooperating with the preliminary crushing mechanism and the discharge mechanism.

[0004] In the above-mentioned prior art, bones are added to the crushing area for preliminary crushing. The crushed bones fall to the bottom of the hopper and are blocked by the baffle, thus unable to be discharged. Then the push rod is pushed to drive the discharge frame and the baffle, the baffle is gradually separated from the hopper, and the discharge frame gradually moves to the bottom of the frame, and the crushed bones enter the frame. Then the reverse operation is performed, the hopper is blocked again, and the frame carries the bones to the bottom of the crushing blade for crushing. Since the frame is hollow, the bones are moved by the frame moving on the frame and scraping the bones, so the bones are inside the frame and in contact with the frame. Since there is a gap between the frame and the frame, the bone powder will adhere to the frame and cannot be completely pushed out, and there is also a gap between the baffle and the hopper. The bone powder accumulated at the bottom of the hopper is easy to flow out through such gaps. Therefore, when the frame moves and the crushing knife is crushed, the bone ashes will splash, causing the top of the crushing blade and the frame to be covered with bone powder, thereby polluting the environment. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that, due to the hollow setting of the material frame, the bones are moved by the material frame moving on the frame to scrape the bones, so the bones are inside the material frame and in contact with the frame, and because there is a gap between the material frame and the frame, the bone powder will adhere to the frame and cannot be completely pushed out, and there is also a gap between the baffle and the hopper. The bone powder accumulates at the bottom of the hopper and easily flows out through such gaps. Therefore, when the material frame moves and the crushing knife crushes, the ashes will splash, causing the top of the crushing blade and the frame to be covered with bone powder, thereby polluting the environment.

When it moves and contacts the second rotating rod, the deflection plate deflects with the rotating shaft as the axis, and the deflection plate drives the second spring to twist and deform. When the deflection plate is separated from the second rotating rod, the elasticity of the second spring drives the deflection plate back to its original position to continue cleaning. Therefore, cleaning can be achieved under the cover of the second rotating rod.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, the staff arranges the crushing assembly inside the crushing box to limit the diffusion of bone powder, and starts the first cylinder to drive the material blocking plate to rise and fall, and the material blocking plate is separated from the discharge port. The crushed bone powder slides onto the receiving plate through the slope. When the discharged aggregate reaches a certain amount, the first cylinder pushes the material blocking plate to move down to block the discharge port, and the material blocking plate drives the fixed rod to move, and the fixed rod drives the rack to move, and the rack is meshed with the second gear to make the second gear rotate, and the second gear drives the first rotating rod to rotate, and the first rotating rod drives the knocking protrusion to rotate, and the knocking protrusion knocks on the slope, so that the ashes on the slope slide into the receiving plate, thereby avoiding the accumulation of ashes.

[0018] 2. In the present invention, when the crushing knife group is crushing up and down, the ashes splashed will accumulate on the crushing knife group. Therefore, after the bone powder is crushed, the crushing knife group rises to the highest point, and the second cylinder is started. The second cylinder drives the receiving plate to enter the inside of the crushing box, and the bone powder on the receiving plate is squeezed by the inner wall of the top of the collecting trough and slides into the collecting trough for collection. When the receiving plate moves, it pulls the traction rope, and the traction rope is stretched, and drives the cleaning plate to move along the bracket to clean the top of the crushing knife group. When the cleaning plate moves, it squeezes the first spring. When the receiving plate returns to its original position, the first spring pushes the cleaning plate back to its original position.

[0034] In this embodiment, the staff adds the bones to the top of the processing box 1, starts the first motor 11, and the first motor 11 drives a crushing roller 12 to rotate. The crushing roller 12 drives another crushing roller 12 to rotate through the first gear 13, thereby crushing the bones. The crushed bones fall onto the guide slope 14 for collection. The staff sets the crushing component inside the crushing box 2 to limit the diffusion of bone powder. By starting the first cylinder 32 to drive the blocking plate 33 to rise and fall, the blocking plate 33 is separated from the discharge port, and the crushed bone powder passes through the slope 2 1 slides onto the receiving plate 513. When a certain amount of aggregate is discharged, the first cylinder 32 pushes the blocking plate 33 to move down to block the discharge port. The blocking plate 33 drives the fixing rod 34 to move.

[0035] like Figure 1 - Fig. 9 As shown, the crushing assembly includes a second motor 51, which is fixed to the side of the top of the crushing box 2 away from the fixed plate 31, and the bottom end of the second motor 51 is transmission-connected with a second rotating rod 511, which penetrates the crushing box 2 and is rotatably connected with the crushing box 2, and a reciprocating groove 5111 is provided at the bottom end of the second rotating rod 511, and the second rotating rod 511 is threadedly connected with a crushing knife group 512 through the reciprocating groove 5111, and both sides of the crushing knife group 512 are slidably connected with the crushing box 2, and the bottom end of the crushing knife group 512 is slidably connected with a receiving plate 513, and the receiving plate 513 is slidably connected with the crushing box 2 and the processing box body 1, and the receiving plate 513 is fixedly connected with a second cylinder 514 on the side close to the processing box body 1, and the second The cylinder 514 is fixed inside the processing box 1, and the cleaning assembly includes two groups of brackets 52, each group of brackets 52 is fixed on both sides of the top of the crushing knife group 512, and a cleaning plate 521 is slidably connected in the middle of each group of brackets 52. The two ends of the cleaning plate 521 are fixedly connected with a first spring 522, the first spring 522 is sleeved on the bracket 52, and one end is fixedly connected to the bracket 52, and a traction rope 523 is fixedly connected in the middle of the cleaning plate 521. Two guide ring frames 524 are fixedly connected in the middle of the top of the crushing knife group 512 away from the processing box 1, and the traction rope 523 is slidably connected to the guide ring frame 524. The end of the traction rope 523 away from the cleaning plate 521 slides through the crushing box 2 and is fixedly connected to the receiving plate 513.

[0036] In this embodiment, the second motor 51 is started to drive the second rotating rod 511 to rotate, and the second rotating rod 511 drives the crushing knife group 512 to move up and down through the reciprocating groove 5111 to crush the aggregate on the receiving plate 513. When the crushing knife group 512 is crushed up and down, the ashes will be splashed and accumulated on the crushing knife group 512. Therefore, after the bone powder is crushed, the crushing knife group 512 rises to the highest point, and the second cylinder 514 is started. The second cylinder 514 drives the receiving plate 513 to enter the crushing box 2 Inside, the bone powder on the receiving plate 513 is squeezed by the inner wall of the top of the collecting trough 22 and slides into the collecting trough 22 for collection. When the receiving plate 513 moves, it pulls the traction rope 523, and the traction rope 523 is stretched, and drives the cleaning plate 521 to move along the bracket 52 to clean out the top of the crushing knife group 512. When the cleaning plate 521 moves, it squeezes the first spring 522. When the receiving plate 513 returns to its original position, the first spring 522 pushes the cleaning plate 521 back to its original position.

[0037] like Figure 1 - Fig. 9 As shown, one end of the cleaning plates 521 that are close to each other is fixedly connected with a rotating shaft 5212, the middle part of the rotating shaft 5212 is rotatably connected with a deflection plate 5211, the deflection plate 5211 is rotatably connected to the cleaning plate 521, a rotating groove 5213 is opened inside the deflection plate 5211 close to the side of the cleaning plate 521, the deflection plate 5211 is located inside the rotating groove 5213 and is fixedly connected with a second spring 5214, and the other end of the second spring 5214 is fixedly connected to the rotating shaft 5212.

[0040] In this embodiment, the part of the traction rope 523 outside the crushing box 2 is up and down, and is supported in an arc state by the pulley 534. Therefore, the force generated during the stretching of the traction rope 523 pulls the cleaning plate 521 to move and also presses the pulley 534. The pulley 534 presses the limiting slide groove 531 through the limiting slider 532, which can help stretch the traction rope 523 and avoid wear caused by large friction between the traction rope 523 and the crushing box 2.

[0041] Working principle: First, the staff adds the bones to the top of the processing box 1 and starts the first motor 11. The first motor 11 drives a crushing roller 12 to rotate. One crushing roller 12 drives another crushing roller 12 to rotate through the first gear 13, thereby crushing the bones. The crushed bones fall onto the guide slope 14 for collection. The staff sets the crushing component inside the crushing box 2 to limit the diffusion of bone powder. By starting the first cylinder 32, the material blocking plate 33 is driven to rise and fall. The material blocking plate 33 is separated from the discharge port. The crushed bone powder slides onto the receiving plate 513 through the slope 21. When the discharged aggregate reaches a certain amount, the first cylinder 32 pushes the material blocking plate 33 to move downward to the discharge port. The material inlet is blocked, the blocking plate 33 drives the fixing rod 34 to move, the fixing rod 34 drives the rack 35 to move, the rack 35 meshes with the second gear 41, so that the second gear 41 rotates, the second gear 41 drives the first rotating rod 42 to rotate, the first rotating rod 42 drives the knocking protrusion 43 to rotate, the knocking protrusion 43 knocks on the slope 21, so that the ashes on the slope 21 slide onto the receiving plate 513, so as to avoid the accumulation of ashes, the second motor 51 is started to drive the second rotating rod 511 to rotate, the second rotating rod 511 drives the crushing knife group 512 to move up and down through the reciprocating groove 5111 to crush the aggregate on the receiving plate 513, and when the crushing knife group 512 is crushed up and down, the ashes splash will pile up The bone meal accumulates on the crushing knife group 512, so after the bone meal is crushed, the crushing knife group 512 rises to the highest point, and the second cylinder 514 is started. The second cylinder 514 drives the receiving plate 513 to enter the crushing box 2, and the bone meal on the receiving plate 513 is squeezed by the inner wall of the top of the collecting tank 22 and slides into the collecting tank 22 for collection. When the receiving plate 513 moves, it pulls the traction rope 523, and the traction rope 523 is stretched, and drives the cleaning plate 521 to move along the bracket 52 to clean the top of the crushing knife group 512. When the cleaning plate 521 moves, it squeezes the first spring 522. When the receiving plate 513 returns to its original position, the first spring 522 pushes the cleaning plate 521 back to its original position, and The buffer member provided can help to stretch the traction rope 523, and avoid wear caused by large friction between the traction rope 523 and the crushing box 2. The movement of the cleaning plate 521 drives the movement of the deflection plate 5211, and the deflection plate 5211 cleans one side of the second rotating rod 511 horizontally. If it moves and contacts with the second rotating rod 511, the deflection plate 5211 deflects with the rotating shaft 5212 as the axis, and the deflection plate 5211 drives the second spring 5214 to twist and deform. When the deflection plate 5211 is separated from the second rotating rod 511, the elasticity of the second spring 5214 drives the deflection plate 5211 back to its original position, thereby continuing to clean. Therefore, cleaning can also be achieved under the cover of the second rotating rod 511.
