Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of livestock breeding, especially to a dung granulator for livestock breeding. BACKGROUND

[0002] Livestock breeding refers to the activity of feeding and breeding livestock and poultry, and a large amount of dung is produced in the breeding process. If the dung is not treated in time, it will cause serious pollution to the environment. The dung is made into granules, which can reduce the volume and odor of the dung, facilitate storage and transportation, and also convert the dung into organic fertilizer, realize resource recycling, reduce breeding cost, avoid soil and water pollution caused by random stacking of dung, and be conducive to the protection of ecological environment and sustainable development.

[0003] The dung granulator currently used has a simple structure and single function, and can only produce granules of a specific particle size. This situation cannot meet the multiple requirements of different uses for granule pore size, greatly limits the scope of application, and lacks flexibility. In addition, the formed dung granules are easily adhered to each other during the production and discharge of dung granules, which greatly affects the subsequent use and makes the quality of finished granules poor.

[0004] Therefore, a dung granulator for livestock breeding is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL

[0013] Compared to existing technologies, the advantages of this invention are as follows: The extrusion mechanism conveys the poured-in feces, causing it to be squeezed out through the granulation holes and formed into cylindrical feces. Simultaneously, the pelletizing mechanism pelletizes the cylindrical feces into fecal pellets. Depending on the application, the positioning mechanism adjusts the front-to-back and left-to-right positions of the extrusion mechanism, allowing it to operate within three pelletizing cylinders. Each of the three cylinders has a large pelletizing hole, a medium pelletizing hole, and a small pelletizing hole. The pore size of the pelletizing hole is larger than that of the medium pelletizing hole, which in turn is larger than that of the small pelletizing hole. Therefore, fecal pellets of different sizes can be manufactured to meet the needs of different applications, thus improving the applicability and flexibility. After the shaped fecal pellets are made, they fall onto the collection hopper and are discharged from the discharge frame. During this process, the falling fecal pellets are dried by a drying mechanism to reduce their moisture content, keep them dry, reduce pellet sticking, and improve the quality of the finished pellets.
