Description

Technical Field

[0001] This utility model relates to a pre-crushing machine, specifically a pre-crushing machine for the harmless treatment of diseased and dead animals, belonging to the technical field of harmless treatment of diseased and dead livestock and poultry. Background Technology

[0002] Dead animals are dangerous sources of infection, as they may carry a large number of pathogenic microorganisms (including viruses, bacteria, parasites, etc.). Dead animals must be disposed of in a harmless manner. This is primarily to completely block the spread of pathogens, prevent the spread of major zoonotic diseases and animal epidemics, and fundamentally safeguard public health and livestock safety. Secondly, this measure can effectively protect the ecological environment, prevent the decomposition of carcasses from polluting the soil, water sources, and air, and eliminate the attraction of mosquitoes, flies, rodents, and other vectors that could lead to secondary disease transmission. Before the harmless disposal of dead animals, they are generally pre-crushed.

[0003] In the pretreatment of dead animals, crushers are generally used to crush them. However, animal tissues contain a large amount of oil and protein. During the crushing process, they are squeezed and heated by friction, which makes them exhibit "sticky" physical properties. They adhere firmly to the blades and shaft surfaces of the crushing rollers like glue. They are also rich in hair and connective tissue. Hair and fascia have a strong wrapping property and can easily wrap around the cutter shaft and blades, carrying other debris and forming an increasingly thick layer of adhesion. Therefore, uneven adhesion can lead to dynamic imbalance, causing abnormal vibration of the equipment. In the long run, this can seriously damage bearings, gearboxes, and motors. The wrapping of hair and tough tissue may seal the connection between the cutter shaft and the bearing housing, leading to oil contamination, damage to the seals, and ultimately allowing blood and dirt to enter the bearings, causing rapid bearing damage. Moreover, the adhered organic residue is a perfect breeding ground for pathogenic microorganisms (bacteria, viruses). If it is not cleaned in time, it will cause serious cross-contamination, violating the original purpose of harmless treatment. Utility Model Content

[0004] The purpose of this invention is to provide a pre-crusher for the harmless treatment of dead animals in order to solve the above problems. It can clean the animal tissue and hair remaining inside the crushing box and prevent residue from remaining in the edge gaps.

This cleans the animal tissue and hair remaining inside the crushing box, preventing residue from remaining in the edge gaps. Attached Figure Description

A positioning plate 209 is detachably connected to the other side of the installation plate 208, and a wire brush 210 is fixedly connected to the positioning plate 209.

[0024] As a technical optimization of this utility model, the rotating groove 203 is circular in shape, and both sides of the slider 204 are arc-shaped, so that the slider 204 can rotate.

[0025] As a technical optimization of this utility model, a limiting structure 3 is installed on the fixed plate 201 and the slider 204. The limiting structure 3 includes a limiting ring 306. The limiting ring 306 is fixedly connected to the outer end of the slider 204. The limiting ring 306 abuts against the fixed plate 201. A positioning ring 307 is fixedly connected to the other side of the slider 204. The positioning ring 307 abuts against the fixed plate 201, thereby limiting the slider 204.

[0026] As a technical optimization of this utility model, a fixing block 301 is fixedly connected to the side of the fixing plate 201, and abutting blocks 302 are fixedly connected to both sides of the limiting ring 306. The fixing block 301 and the abutting block 302 abut against each other, thereby limiting the rotation of the slider 204.

[0027] As a technical optimization of this utility model, a fixing plate 303 is fixedly connected to the top of the fixing plate 201, and a limiting plate 304 is fixedly connected to the outer end of the limiting ring 306. A fixing post 305 is inserted into the fixing plate 303 and the limiting plate 304, so as to fix the slider 204.

[0028] As a technical optimization of this utility model, a fixing structure 4 is installed on the mounting plate 208 and the positioning plate 209. The fixing structure 4 includes a fixing ring 401. The fixing ring 401 is fixedly connected to the positioning plate 209. The fixing ring 401 and the mounting plate 208 are engaged, thereby fixing the positioning plate 209.

[0029] As a technical optimization of this utility model, a fixing rod 402 is slidably connected inside the mounting plate 208. The fixing rod 402 and the fixing ring 401 are inserted into each other. The other end of the fixing rod 402 is fixedly connected to a limiting plate 403. The limiting plate 403 and the mounting plate 208 are slidably connected. A spring 404 is fixedly connected between the limiting plate 403 and the mounting plate 208, so that the fixing ring 401 can be installed.

[0030] As a technical optimization of this utility model, a crushing structure 5 is installed on the crushing box 1. The crushing structure 5 includes a fixed shaft 501. Two fixed shafts 501 are rotatably connected in a parallel and symmetrical relationship inside the crushing box 1. A crushing roller 502 is fixedly connected to the fixed shaft 501. Gears 503 are fixedly connected to the side ends of the two fixed shafts 501. The two gears 503 mesh with each other. A hopper 504 is fixedly connected to the top of the crushing box 1. A motor 505 is installed on the side end of the crushing box 1. The output end of the motor 505 is fixedly connected to one of the fixed shafts 501 through a coupling, thereby enabling the crushing of dead animals.

[0031] In use, when crushing diseased or dead animals, the animals are placed into the crushing chamber 1 through the feeding hopper 504. The motor 505 is then started, and the meshing of two gears 503 drives two fixed shafts 501 to rotate in opposite directions. This allows the two opposing crushing rollers 502 to pre-crush the animals. After prolonged operation, the motor 505 is turned off, and the fixed column 305 is pulled upwards. When the fixed column 305 engages with the fixed plate 303 and the limiting plate 30... 4. After separation, slide the slider 204 outward in the slide groove 202. When the slider 204 slides into the rotating groove 203, it rotates through the rotating groove 203, thus driving the rotating shaft 205 and the connecting plate 206 to rotate. After rotating until the abutting block 302 and the fixing block 301 on the other end of the limiting ring 306 abut against each other, the positions of the sealing plate 207 and the mounting plate 208 can be interchanged. Then, slide the slider 204 into the slide groove 202 again. When the fixing plate 303 and the limiting plate 304 abut against each other again... After the fixing post 305 is inserted, the slider 204 can be fixed again. Therefore, the positioning plate 209 and wire brush 210 can be inserted into the crushing box 1. The motor 505 is restarted, and cleaning agent is added to the crushing roller 502. The rotating crushing roller 502, in contact with the wire brush 210, cleans away any remaining animal tissue and hair, preventing residue from remaining in the edge gaps. Then, the cleaning agent on the crushing roller 502 is rinsed off with a high-pressure spray gun. After adjusting the slider 204 to rotate, the positions of the sealing plate 207 and the mounting plate 208 are interchanged again. The side of the crushing box 1 is sealed by the sealing plate 207. Then, the fixing rod 402 is pressed. After the fixing rod 402 and the fixing ring 401 are separated, the positioning plate 209 is removed to clean the wire brush 210. After cleaning, the fixing rod 402 and the fixing ring 401 are reconnected by the spring 404 and the limiting plate 403, so that the positioning plate 209 and the wire brush 210 can be fixed again.
