Description

Technical Field

[0001] The invention belongs to the technical field of piglet breeding and relates to feed processing equipment for piglets. Background Art

[0002] Starter feed and nursery feed are feeds formulated to replace whole milk, with their primary ingredients being dairy byproducts. Starter feed is for suckling piglets, with its primary function being to induce early feeding, strengthen the gastrointestinal tract, and supplement the nutritional deficiencies of breast milk after three weeks. It is easily digestible and prevents diarrhea. Nursery feed is for weaned piglets, with its primary function being to be easily digestible, prevent diarrhea, and promote the transition of piglets from breast milk to corn and soybean meal-based feeds. The nutrient solution composition and concentration of starter feed and nursery feed produced by different manufacturers vary, including materials such as powdered corn, dairy products, fish meal, puffed soybeans, and soy protein concentrate. These starter feed and nursery feed ingredients generally undergo processes such as crushing, impurity removal, puffing, and re-crushing during production. The puffing process, in particular, matures the feed, helping to meet the feed production requirements for fresh-mature piglet rearing.

[0003] The actual floor space occupied by existing feed processing equipment is relatively large. For example, the extrusion screw in the puffing process has a large diameter and mostly extends in a horizontal spiral direction, so it is large in size and has high space costs. Secondly, the distribution span of different production processes is relatively large, which will also lead to high material transportation costs and significantly affect production efficiency.

[0035] Specifically, the stand 1 provides a reasonable assembly basis for the material grading unit 21, the mixing unit 22, the tumbling unit 23, the dividing unit 24 and the puffing and crushing unit 25, and realizes integrated installation in a coordinated manner, which not only shortens the feeding path, but also compresses the actual floor space of the entire equipment, which is beneficial to saving costs and improving the comprehensive utilization rate of the equipment. More specifically, the airflow feeding pipe 3 serves as a feeding channel, and can transport materials with wind as the power, reducing the investment in mechanical feeding mechanisms, which is beneficial to reducing the probability of equipment failure; the airflow feeding pipe 3 drives different feed raw materials such as powdered corn, dairy products, imported fish meal, puffed soybeans and soybean concentrated protein into the four material grading units 21, and the first material dispensing mechanism 212 disperses the agglomerated materials while dispensing the materials, so that the materials can enter the mixing unit 22 more evenly; each two material grading units 21 are grouped together and firstly drive their respective materials into two different The mixing unit 22 performs premixing. The second material transfer mechanism 26 in the mixing unit 22 transfers the premixed materials from the mixing unit 22 to the tumbling and kneading unit 23 for tumbling and mixing. All materials are tumbled and kneaded at a certain frequency and duration in the tumbling and kneading unit 23. The material distribution unit 24 then distributes the tumbled materials to different puffing and crushing units 25. Although the diameter of the puffing and granulating unit 25 is significantly smaller than that of existing large-scale equipment, the combined action of multiple puffing mechanisms and the extrusion die plate 255 ensures a sufficient working volume to ensure production efficiency in the workshop. After the puffed feed is extruded from the extrusion die plate 255, it is crushed and granulated by the granulation and crushing mechanism 256. The granulated feed is then discharged from the discharge port 14. The workshop conveyor can transport the granulated feed from below the third gear 13 to the workshop collection equipment. The observation window design allows staff to observe the actual extrusion process of the extruder mechanism in the puffing chamber, allowing for timely maintenance.

[0036] In order to improve the space intensiveness of the device, the material distribution box 211, the mixing box 221, the tumbling box 231 and the material distribution box 241 provided by the present invention are all 80×80×60 cm. 3 The box body 27, the top and bottom of the box body 27 cooperate with the cam rails provided between the mounting gears, and the box body includes a front box cover 271 and a rear box cover 272 nested in the front and rear, and the inner wall of the rear box cover 272 is a horizontal cylindrical surface, and the cylindrical surface is movably cooperated with the maximum rotation surface of the first material dispensing mechanism 212 and the second material dispensing mechanism 26. Among them, the box body adopts the combination of the front box cover 271 and the rear box cover 272 to form a material chamber, which can not only meet the movement needs of the material, but also facilitate targeted maintenance of part of the box body and its internal mechanism. The design of the cylindrical surface is conducive to the full transfer of materials from the inside of the box body to another box body in the first material dispensing mechanism 212 and the second material dispensing mechanism 26. The volume design of the box body, especially the fact that the entire equipment can be assembled together in a wall-mounted manner, can greatly ensure the space utilization rate of the equipment while meeting the production volume requirements.

[0037] To improve the transmission performance of the first and second material diverting mechanisms 212 and 26, the present invention provides a combined bearing assembly 4 on the front housing cover 271. The combined bearing assembly 4 is used to reduce the rotational resistance of the first and second material diverting mechanisms 212 and 26. Furthermore, a drumhead groove 273 is provided at the front end of the front housing cover 271. A center hole is provided at the center of the drumhead groove 273 for mounting the combined bearing assembly 4. The design of the drumhead groove 273 and the center hole effectively increases the heat exchange area between the center of the housing and the external environment, reducing moisture in the material during transfer and reducing heat generated along the transmission path, thereby ensuring the normal operation of the equipment.

[0038] In order to improve the utilization rate of the combined bearing component 4, the combined bearing component 4 provided by the present invention includes a central sleeve 41 nested with the center hole and a concentric bearing ring 42 disposed inside the drumhead groove 273. The central sleeve 41 flexibly cooperates with the rotation center of the first and second material selection mechanisms 212 and 26, while the inside of the drumhead groove 273 and the concentric bearing ring 42 flexibly cooperate with the rotation end surfaces of the first and second material selection mechanisms 212 and 26. The mating surfaces of the central sleeve 41 and the concentric bearing ring 42 with the first and second material selection mechanisms 212 and 26 are smooth, and the concentric bearing ring 42 also increases the radial working span and transmission area of the combined bearing component 4, which has a positive significance for improving the rotational stability of the first and second material selection mechanisms 212 and 26.

[0039] In order to improve the stability of all boxes on the stand 1, the present invention provides a plurality of horizontal connection holes 274 at the corners of the drum surface groove 273 on the front box cover 271.

Among them, after the first transmission sleeve 212b and the first outer ring 212c are connected in transmission, the power of the rotating shaft can be effectively transmitted to the radial blade group 212d and the spiral blade 212e, and the combination of the two is a hollow structure. On the one hand, it can provide a larger heat dissipation area for the box body and external equipment, and on the other hand, it can reduce the thickness of the material between the inner wall of the box body and the first material selection mechanism 212. In addition, due to the cutting effect of the spiral blade 212e, the thickness will not cause large-scale agglomeration of the material during the material selection process, and will not increase the working torque of the first rotating shaft 212a, thereby improving the material selection efficiency of the first material selection mechanism 212, and to a certain extent, it is also beneficial to extend the actual service life of the first material selection mechanism 212.
