Description

Technical Field

[0001] The invention relates to the technical field of feed processing, in particular to a fine grinding machine for feed preparation. Background Art

[0002] In many fields such as animal husbandry, aquaculture and pet breeding, feed is the core nutritional supply element to ensure the growth, development and health of animals. Its quality is closely related to the sophistication of the processing technology. The grinding mill undoubtedly occupies a key position in the feed processing chain. In feed processing practice, it is usually necessary to use a grinding mill to convert various feed raw materials into fine powder, and then use the powdered raw materials as the basis to promote the subsequent finished product processing process. However, looking at the design structure of the current feed grinding mill, it is not difficult to find that there are several areas that need to be improved. In terms of its working principle, most grinding mills at this stage mainly rely on the rotation of the roller to realize the conversion of large-particle feed into powder, but in actual operation, The working area of ​​the roller is concentrated at the bottom. Only when the roller completes one revolution inside the equipment can a complete round of grinding be carried out on all the feed to be processed. Since it takes a long time for the roller to rotate once, the overall grinding efficiency is directly limited, which is difficult to meet the demand rhythm of high-speed and mass production in the modern feed industry. At the same time, in the front-end operation link of feed grinding, manual feed feeding is currently widely used. Operators need to be on duty continuously and frequently add feed to the grinder manually, which undoubtedly greatly increases labor costs and labor intensity. Manual operation is prone to introduce subjective factors, resulting in unstable feed volume, which in turn affects the consistency of grinding quality and is not conducive to building a standardized and automated feed processing production line.

[0047] Specific usage method and function of this embodiment:

[0048] In the present invention, as Figures 1 to 8 shown, a sealing plate 104 is inserted at the material taking port 1012 inside the main body 101 to achieve the sealing function. Then, the limiting plate 1021 inside the movable groove 102 is slid downward until it is inserted into the limiting groove 1041 of the sealing plate 104, thereby fixing the sealing plate 104 inside the material taking port 1012. A grinding roller 201 is rotatably installed inside the main body 101 to ensure that the toothed ring 202 at the bottom of the grinding roller 201 forms an effective transmission connection with the driving gear 103 on the rear back plate 1011 of the main body 101. Subsequently, the substrate 301 is firmly installed inside the main body 101 by bolts, so that the guiding frame 3011 at the upper end of the substrate 301 is located inside the grinding roller 201. A lifting plate 3012 is slidably installed on the guiding frame 3011, and the lifting plate 3012 is controlled by the driving screw 302 on the substrate 301. The lifting plate 3012 is adjusted to the lowest side of the grinding roller 201, and the driven wheel 3021 at the lower end of the driving screw 302 is exposed from the bottom of the main body 101. At the same time, a transmission connection is established between the driven wheel 3021 and the transmission wheel 1031 below the driving gear 103 through a belt. The grinding roller 201 is filled with large particle feed to be ground and processed, and these feeds will fall onto the upper end of the lifting plate 3012. When the equipment starts to work, the motor drives the grinding roller 201 and the driving screw 302 to rotate respectively through the driving gear 103 and the transmission wheel 1031. Due to the speed difference between the driving screw 302 and the grinding roller 201, while the grinding roller 201 rotates, the driving screw 302 will make the lifting plate 3012 rise slowly through its own rotation action, thereby evenly pushing the feed out from the top of the grinding roller 201. As the feed is continuously pushed out, the feed loses the restriction from the grinding roller 201 and scatters around, and falls into the processing area between the grinding roller 201 and the inside of the main body 101. In this processing area, the grinding of the feed is achieved through the friction between the inner wall of the main body 101 and the grinding roller 201. As the feed particles become smaller and smaller during the processing, the finally ground feed powder will gradually slide down to the lower part inside the main body 101. At this time, the limiting plate 1021 is pulled upward to disengage it from the limiting groove 1041, and the sealing plate 104 is removed from the material taking port 1012. Since the grinding roller 201 rotates continuously inside the main body 101, the grinding roller 201 can drive the feed to move inside the main body 101 through friction, so that there will be no material accumulation inside the main body 101. The operator only needs to make good reception at the material taking port 1012.
