Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a feed processing pretreatment equipment for large-scale egg-laying hen farms. Background Technology

[0002] Chicken farming is an important part of agricultural animal husbandry. It involves raising chickens in various ways, such as in mountainous areas, plastic greenhouses, and cages, utilizing their physiological functions to artificially breed and convert plant-based feed into animal energy to produce chicken meat and eggs. Feed is a general term for the food consumed by all domesticated animals. In a narrower sense, feed generally refers to the food consumed by animals raised in agriculture or animal husbandry. Feed includes more than ten types of feed ingredients, such as soybeans, soybean meal, corn, fishmeal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives.

[0003] Before mixing and processing chicken feed, a series of pretreatments are required for the raw materials. Impurity removal and drying are essential operations. Some raw materials with larger particles also need to be crushed and ground. However, in the current market, impurity removal, drying and grinding are carried out separately when pretreating chicken feed raw materials, which increases the workflow and workload, reduces work efficiency, and wastes a lot of labor and time in the process of large-scale chicken farming. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a special chicken feed pretreatment equipment that integrates the removal of impurities, drying, and grinding of chicken feed raw materials, thereby greatly improving operational efficiency.

[0005] This utility model is achieved through the following technical solution: a pre-treatment equipment for feed processing in large-scale egg-laying hen farms, including a frame, a cleaning mechanism and a grinding mechanism on the frame, the cleaning mechanism including a screen box, the screen box being installed on the top of the frame by springs, a feed hopper fixed on the top of the screen box, a vibrating motor fixed on the bottom of the screen box, a first screen, a second screen and a third screen arranged sequentially from top to bottom inside the screen box, a first discharge trough opposite to the third screen on the side wall of the screen box, and a feed inlet communicating with the first discharge trough of the grinding mechanism.

[0006] The impurity removal mechanism in this solution removes impurities from the raw materials through a first screen, a second screen, and a third screen. The removed raw materials then enter the grinding mechanism for grinding through the first discharge trough, achieving integrated impurity removal and grinding operations. This makes the solution convenient to use and greatly improves operational efficiency.

[0007] As an optimization, a hot air blower is installed on the top of the screen box, with the blower's nozzle extending into the screen box. This optimized solution uses the hot air blower to blow hot air into the screen box, drying the raw materials while screening, achieving integrated operations of impurity removal, drying, and grinding, further improving operational efficiency.

[0008] As an optimization, the bottom of the screen box is provided with a slope, and a second discharge chute is provided on the side wall of the screen box opposite to the slope. In this optimized solution, impurities screened out of the screen box fall onto the slope and are discharged from the second discharge chute, facilitating the sliding out of the impurities.

[0009] As an optimization, the grinding mechanism includes a grinding box with two grinding rollers arranged horizontally side by side inside, forming a grinding gap between them. The grinding rollers are rotatably connected to the grinding box via a rotating shaft. A drive motor for driving the rotating shaft is located on the outer wall of the grinding box, and the feed inlet is located above the grinding rollers. In this optimized solution, the drive motor drives the two grinding rollers to rotate, thereby grinding the raw material falling into the grinding gap.

[0010] As an optimization, a baffle is provided above the gap between the outer wall of the grinding roller and the side wall of the grinding box. One end of the baffle is fixed to the side wall of the grinding box, and the other end of the guide plate extends downward at an angle to the top of the grinding roller. This optimization scheme prevents raw materials from falling into the gap between the grinding roller and the side wall of the grinding box through the baffle.

[0011] As an optimization, a third discharge chute is provided at the bottom of the grinding box, and a cover can be detachably installed on the third discharge chute. The ground raw material is discharged from the third discharge chute in this optimized solution.

[0012] As an optimization, a discharge port is provided at the bottom of the first discharge trough, and the inlet is connected to the discharge port through a discharge pipe. A cover plate is provided inside the first discharge trough to close the discharge port, and the end of the cover plate away from the screen box is hinged to the first discharge trough via a hinge shaft. In this optimized solution, when grinding is not required, the discharge port is closed by the cover plate, and the raw material is discharged directly. The cover plate can be rotated around the hinge shaft to open, and after the cover plate is opened, the raw material is discharged into the grinding mechanism through the discharge pipe for grinding, making it more flexible to use. At the same time, the open cover plate also seals the outer port of the first discharge trough, preventing the raw material from being discharged from the outer port of the first discharge trough.

[0013] As an optimization, the hinge shaft and the cover plate are fixedly connected. A handle is fixedly connected to one end of the hinge shaft, and a locking nut is screwed to the other end. In this optimized solution, rotating the hinge shaft with the handle will cause the cover plate to rotate and open. After the cover plate is opened, it is locked in place by the locking nut, keeping the cover plate in the open state.

[0014] As an optimization, the first and second screens are fixed alternately inside the screen box. This optimization extends the raw material screening path and improves screening and drying efficiency.

[0015] The beneficial effects of this utility model are as follows: the impurity removal mechanism removes impurities from the raw materials through the first screen, the second screen and the third screen, and blows hot air into the screen box through the hot air blower to dry the raw materials at the same time as screening. The impurity-removed raw materials enter the grinding mechanism for grinding through the first discharge chute, realizing the integrated operation of impurity removal, drying and grinding, which greatly improves the work efficiency and saves a lot of manpower and time in large-scale chicken farming.

[0016] The first discharge trough is equipped with a cover plate. When grinding is not required, the discharge port can be closed by the cover plate, and the raw material can be discharged directly. The cover plate can be opened by rotating around the hinge shaft. After the cover plate is opened, the raw material is discharged into the grinding mechanism through the discharge pipe for grinding, making it more flexible and convenient to use.
