Description

Technical Field

[0001] The utility model relates to the technical field of ruminant feed processing, in particular to a ruminant feed crushing device. Background Technique

[0002] Ruminants refer to those animals that can chew the food that has been swallowed again in the stomach after soaking and softening for a period of time. Green forage is one of the ruminant feeds. When processing ruminant feeds, a crushing device is needed to crush them.

[0003] In the prior art, it is often necessary to use a hammer mill to crush ruminant feeds. During operation, the material is first impacted by the high-speed rotating hammer blades and is initially broken into small pieces. Under the continuous impact of the hammer blades, the crushed material continuously undergoes strong friction with the sieve plate and is further pulverized.

[0004] When the existing hammer mill processes green forage, due to the high fiber content of green forage, the fibers are easily wound around the sieve plate, and clogging or jamming phenomena are likely to occur. However, since the sieve plate is fixedly installed inside the hammer mill, it is not convenient to disassemble, clean, and replace the sieve plate. Therefore, it is necessary to propose a ruminant feed crushing device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a ruminant feed crushing device, which has the characteristics of being convenient for disassembling, cleaning, and replacing the sieve plate.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A ruminant feed crushing device, including a box body and a sieve plate. A connecting shaft is rotatably connected inside the box body. A plurality of limiting disks are fixedly connected to the outer wall of the connecting shaft. Three mounting rods are fixedly connected between the plurality of limiting disks. Hammer blades staggered with the plurality of limiting disks are arranged on the outer walls of the three mounting rods. An arc-shaped limiting groove is opened on the right side of the inner wall of the box body. One end of the sieve plate extends into the arc-shaped limiting groove. An arc-shaped through groove is penetrated and opened on the left side of the inner wall of the box body. The other end of the sieve plate penetrates through the arc-shaped through groove and is fixedly connected to a connecting plate. The other end of the connecting plate is rotatably connected to a steering shaft. Two pressure-receiving strips are fixedly connected to the outer wall of the steering shaft. Circular holes are opened at the left ends of the two pressure-receiving strips. Two L-shaped fixing frames are installed on the left end face of the box body. Screws are rotatably connected to the left sides of the inner walls of the two L-shaped fixing frames. Moving blocks are threadedly connected to the outer walls of the two screws. Extrusion columns extending into the two circular holes are fixedly connected to the right ends of the two moving blocks.

[0007] To facilitate improving the stability of the movement of the two moving blocks, as an optimization of the ruminant feed crushing device of the present utility model, the two moving blocks and the inner walls of the two L-shaped fixing frames are all slidably connected through sliders and chutes.

[0008] To improve the stability of the installation of the two screws, as an optimization of the ruminant feed crushing device of the present utility model, the other ends of the two screws are rotatably connected to the left side of the box body.

[0009] To facilitate driving the connecting shaft to rotate, as an optimization of the ruminant feed crushing device of the present utility model, the connecting shaft is driven by a motor installed on the right side of the box body.

[0010] To facilitate the rotation of the two screws respectively, as an optimization of the ruminant feed crushing device of the present utility model, the left ends of the two screws are fixedly connected with connecting rods passing through the two L-shaped fixing frames, and the left ends of the two connecting rods are fixedly connected with hand wheels.

[0011] To facilitate feeding and discharging respectively, as an optimization of the ruminant feed crushing device of the present utility model, the upper end of the box body is penetrated and connected with a feed hopper, and the lower end of the box body is provided with a discharge hopper.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] When installing the sieve plate, one end of the sieve plate needs to pass through the arc-shaped through groove and enter the inside of the arc-shaped limiting groove until the connecting plate contacts the box body. Then, the two pressure-receiving strips are rotated to the vertical state, and then the two extrusion columns enter the two round holes and squeeze the two pressure-receiving strips to the right to fix them. At the same time, the sieve plate can be fixed. When removing the sieve plate, the two extrusion columns need to be separated from the two round holes through the reverse steps, and then the two pressure-receiving strips are rotated to the horizontal state, and the sieve plate can be taken out, thereby achieving the purpose of facilitating the disassembly, cleaning and replacement of the sieve plate.

[0022] During use, the feed to be crushed is added to the inside of the box body 1, and the connecting shaft 2 rotates at a high speed, simultaneously driving the three mounting rods 4 and multiple hammer pieces 5 to rotate at a high speed. The feed is impacted by the high-speed rotating hammer pieces 5 and is initially broken into small pieces. Under the continuous impact of the hammer pieces 5, the crushed feed continuously undergoes strong frictional action with the sieve plate 7, thereby enabling the feed to be crushed. The crushed material will fall through the sieve plate 7 and then be discharged.

[0034] In this embodiment: By providing the two mounting seats 18, it is convenient to install and fix the device.

[0035] Working principle: When installing the sieve plate 7, first make one end of the sieve plate 7 pass through the arc-shaped through slot 9 and enter the inside of the arc-shaped limiting slot 8. The arc-shaped limiting slot 8 can limit one end of the sieve plate 7 until the connecting plate 10 contacts the box body 1. Then, make the two pressure-receiving bars 17 rotate along with the steering shaft 11 until the two pressure-receiving bars 17 are in the vertical state. At this time, the positions of the two round holes 15 correspond to the two extrusion columns 16. Then, rotate the two screw rods 13 respectively through the two handwheels and the two connecting rods, and further drive the two moving blocks 14 and the extrusion columns 16 to move to the right until the two extrusion columns 16 enter the two round holes 15 and squeeze the two pressure-receiving bars 17 to the right and fix them. At the same time, the sieve plate 7 can be fixed. At this time, the positions of the two extrusion columns 16 can be limited through the two round holes 15. When the sieve plate 7 needs to be removed, the two extrusion columns 16 need to be disengaged from the inside of the two round holes 15 through the reverse steps, and then the two pressure-receiving bars 17 are rotated to the horizontal state, and the sieve plate 7 can be taken out, so as to achieve the purpose of facilitating the disassembly, cleaning and replacement of the sieve plate 7;

[0036] During use, first add the feed to be crushed into the box body 1 through the feed hopper, and drive the connecting shaft 2 to rotate at a high speed through the motor 6, and at the same time drive the three mounting rods 4 and the multiple hammer pieces 5 to rotate at a high speed. The feed is impacted by the high-speed rotating hammer pieces 5 and is initially broken into small pieces. Under the continuous impact of the hammer pieces 5, the broken feed continuously has a strong frictional effect with the sieve plate 7, and thus the feed can be crushed. The crushed material will fall through the sieve plate 7 and then be discharged through the discharge hopper.
