Description

Technical Field

[0001] The utility model relates to the technical field of animal corpse processing, and more specifically to a device for pre-processing dead animal corpses. Background Art

[0002] Pretreatment of dead animal carcasses is an important step in ensuring public health safety and environmental protection. It reduces the risk of pathogen transmission and reduces the difficulty of subsequent treatment. Pretreatment is an important part of the management of dead animal carcasses. It helps improve treatment efficiency, reduce costs, ensure public health safety, and is conducive to resource recycling.

[0003] The purpose of pre-treatment of existing diseased and dead animals is to reduce the risk of pathogen transmission, prevent environmental pollution, prepare for subsequent treatment (such as incineration, composting, biodegradation, etc.), and improve the efficiency of subsequent treatment.

[0004] In actual use of the existing technology, since it takes longer time to fully treat the broken animal carcasses during incineration, composting, etc., the degradation process is slow, and the large pieces of unbroken carcasses will take up more space, which is easy to cause inconvenience especially during storage and transportation. Therefore, a pretreatment device for dead animal carcasses is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In response to the problems existing in the prior art, the utility model provides a device for pre-processing dead animal carcasses, which starts a motor to drive a driving roller to rotate and drives two conveyor belts to move inward at the same time through two meshing gears to automatically transport the animal carcasses inward and drop them onto the crushing rollers. When the gears rotate, the driving wheel, the driven wheel and the belt cooperate to drive the two crushing rollers to rotate inward at the same time to crush the animal carcasses, breaking larger animal carcasses into smaller blocks for easy subsequent processing. Crushing can accelerate the biodegradation process and produce higher quality fertilizer or biogas. The crushed carcasses are easier to carry and load into transportation vehicles.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) This solution starts the motor to drive the driving roller to rotate and drives the two conveyor belts to move inward at the same time through the cooperation of two meshing gears to automatically transport the animal carcasses inward and drop them on the crushing roller. When the gears rotate, the driving wheel, the driven wheel and the belt drive the two crushing rollers to rotate inward at the same time to crush the animal carcasses, breaking the larger animal carcasses into smaller pieces for easy subsequent processing. Crushing can accelerate the biodegradation process and produce higher quality fertilizer or biogas. The crushed carcasses are easier to carry and load into transportation vehicles. The crushed animal carcasses fall on the discharge plate and automatically slide outward through the discharge port due to the crushing of the discharge plate, making them easier to collect uniformly.

[0018] (2) This solution is connected to an external tank storing disinfectant through an external pipe, and the disinfectant is pumped out by starting the pump and sprayed out through the atomizing nozzles on the upper nozzle and the side nozzle. When the animal carcass moves on the conveyor belt, the disinfectant is sprayed through the upper nozzle to disinfect the surface of the animal carcass. When the animal carcass falls, the disinfectant is sprayed through the side nozzle to disinfect its back, so as to kill the pathogens carried on the animal carcass and reduce the risk of pathogen transmission.
