Description

Technical Field

[0001] The utility model belongs to the technical field of animal husbandry, and particularly relates to a grinding device for pig bone powder used as feed. Background Art

[0002] Feed is a general term for food for animals raised by all people, including more than ten types of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives, etc. Among them, bone and meat meal is a product made from livestock carcasses, residual minced meat, bones, and internal organs that are not suitable for consumption in livestock and poultry slaughterhouses, and is made through high-temperature cooking, defatting, drying, and crushing. It is a good source of protein, calcium, phosphorus, and vitamin B12 for pigs, chickens, ducks, etc. Among the types of bone and meat meal, pig bone meal is widely used. It needs to be cooked, disinfected, dried, and crushed and ground during the production and processing process. Due to the high hardness of pig bones, workers usually use grinding equipment to assist in the crushing and grinding of pig bones to improve production efficiency, but it still has the following disadvantages in actual use:

[0003] 1. The utility model with publication number CN215429291U discloses a pig bone crushing device for processing pork powder feed, wherein an upper shell is fixedly installed on the upper surface of the lower shell, a pillar is fixedly installed on the lower surface of the lower shell, a support rod is fixedly installed on the outer surface of the lower shell, a transmission shaft housing is fixedly installed on the upper surface of the upper shell, and a support rod is fixedly installed on the bottom of the transmission shaft housing. The pig bone crushing device has a simple structure and is easy to operate. However, in actual use, due to the large size of the pig bones, when crushing the larger pig bones, it is difficult for the pig bones to rely on gravity and the rotation of the first crushing gear to enter between the two first crushing gears for crushing, which increases the labor intensity and safety hazards of the staff;

[0004] 2. When actually using the grinding equipment for pig bone powder, it is usually divided into two parts: a crushing structure and a grinding structure. The pig bones are crushed to a certain size before being ground. The production time is long, and the two parts need to be cleaned separately, which is time-consuming and laborious. Utility Model Content

[0013] Furthermore, a discharge pipe is welded through the bottom of the grinding box, a connecting pipe is welded through one end of the discharge pipe, and a blower is fixedly connected to the top of the connecting pipe;

[0014] When the pig bone powder is crushed and ground, the air flow driven by the blower can further drive the pig bone powder in the grinding box into the inner side of the discharge pipe through the feeding hole, and be discharged through the connecting pipe with the downward airflow, thereby improving production efficiency, avoiding pig bone powder from being blocked in the feeding hole, and reducing the difficulty of cleaning.

[0015] Furthermore, a telescopic rod is slidably connected to the bottom of the hydraulic cylinder, a support plate is connected to the bottom of the telescopic rod, the telescopic rod is inserted through the top of the top cover, a grinding motor is fixed to the top of the support plate, the rotating grinding roller is rotatably connected to the bottom of the grinding motor, the rotating grinding roller is inserted through the bottom of the support plate, and the rotating grinding roller is attached to the inner wall of the grinding box;

[0016] The hydraulic cylinder can drive the telescopic rod to extend and retract, and further drive the rotating grinding roller to move up and down. The pig bones can be squeezed and crushed by the rapid movement of the rotating grinding roller. At the same time, the grinding motor drives the rotating grinding roller to rotate, so that the pig bone powder can be squeezed and ground, thereby improving production efficiency. A pressure sensor can be set at the bottom of the support plate to avoid damage to the rotating grinding roller and the replaceable grinding roller due to excessive pressure.

[0017] Furthermore, a positioning groove is provided on the outer circumference of the replaceable grinding roller, a material passage hole is provided through the top of the replaceable grinding roller and the second rotating gear, the limiting frame is inserted into the bottom of the positioning groove, and the feeding pipe is located between the second rotating gear and the rotating grinding roller;

When cleaning, only the inside of the grinding box, the bottom of the rotating grinding roller and the replaceable grinding roller need to be cleaned. The operation is simple and convenient, which reduces the labor intensity of the staff.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model solves the problem that the pig bone crushing device has a simple structure and is easy to operate by arranging a top cover and a replaceable grinding roller. However, in actual use, due to the large size of the pig bones, it is difficult for the pig bones to rely on gravity and the rotation of the first crushing gear to enter between the two first crushing gears for crushing when crushing the larger pig bones, which increases the labor intensity of the staff and safety hazards. After the pig bones enter the grinding box, the hydraulic cylinder drives the rotating grinding roller to move downward quickly to squeeze and crush the pig bones, avoiding the difficulty of the pig bones entering the gap between the two crushing gears, improving processing efficiency, and reducing safety hazards.

[0021] 2. The utility model solves the problem that the pig bone powder grinding equipment is usually divided into two parts, namely, a crushing structure and a grinding structure, and the pig bones are ground after being crushed to a certain size, which takes a long time to produce and needs to be cleaned separately, which is time-consuming and laborious. When the hydraulic cylinder drives the rotating grinding roller to move downward and the pig bones are crushed by the rotating grinding roller and the replaceable grinding roller, the grinding motor drives the rotating grinding roller to rotate and the pig bones are ground, so that the pig bones are squeezed, crushed and ground at the same time, and the blower drives the flow of air so that the ground pig bone powder can be discharged at the same time, which greatly improves the production efficiency. When cleaning, it is only necessary to clean the inside of the grinding box, the bottom of the rotating grinding roller and the replaceable grinding roller. The operation is simple and convenient, which reduces the labor intensity of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
