Description

Technical Field

[0001] This utility model belongs to the field of feed processing technology, and in particular relates to a crushing and mixing device for feed. Background Technology

[0002] In the feed processing industry, grinding and mixing are key steps in improving feed palatability and nutritional uniformity, directly affecting feed quality and breeding outcomes. Currently, most feed grinding and mixing devices on the market have limitations in structural design, particularly in terms of ease of disassembly and cleaning, making it difficult to meet the demands for efficient and hygienic processing.

[0003] In existing equipment, the crushing components are typically fixedly connected to the mixing shaft or frame, such as through welding or integral molding. This design leads to feed debris easily remaining on the surface of the crushing blades after prolonged use. Because these components cannot be disassembled individually, cleaning requires operating the entire mixing structure, which is not only time-consuming and labor-intensive but also makes it difficult to thoroughly remove residual material from the crevices. Residual feed is prone to bacterial growth and mold in humid environments, affecting the hygienic quality of subsequent feed processing and potentially posing a health threat to farmed animals if moldy substances are mixed into new feed.

[0004] To address these issues, we provide a feed grinding and mixing device. Utility Model Content

[0005] The purpose of this invention is to provide a feed crushing and mixing device. Through the action of the mixing frame, which is connected to the motor output shaft via a transmission rod, the crushing blade can be rotated to crush the feed. The mixing frame and the crushing blade are detachable. The crushing blade is fixed to the positioning tube, which is fitted into the mounting groove of the mounting rod via an mounting strip and secured by threaded holes and screws on the mounting plate. After mixing, the screws can be unscrewed, and the positioning tube along with the crushing blade can be removed from the mounting rod. This facilitates thorough cleaning of any residual feed on the surface of the crushing blade, solving the problem in existing devices where residual feed easily breeds bacteria and molds in humid environments, affecting the hygienic quality of subsequent feed processing and potentially threatening the health of farmed animals by moldy substances mixing into new feed.

[0047] Specifically, a limiting rod 16 is fixed at the bottom of the mixing frame 6; a discharge trough 17 is opened at the bottom of the mixing shell body 1, and a support strip 18 is fixed at the bottom of the mixing shell body 1; a limiting tube 19 is fixed in the center of the support strip 18; the limiting rod 16 is rotatably connected to the inner wall of the limiting tube 19.

[0048] Furthermore, several cleaners 20 are fixed on both sides of the mixing frame 6; each cleaner 20 includes a cleaning shell 21, which is fixedly connected to the inner wall of the mixing frame 6; a telescopic rod 22 is fixed inside the cleaning shell 21; a connecting plate 23 is fixed to one end of the telescopic rod 22, and a spring 24 is fixed between the connecting plate 23 and the inner wall of the cleaning shell 21; a connecting rod 25 is fixed to one side of the connecting plate 23; a scraper 26 is fixed to one end of the connecting rod 25, and the scraper 26 matches the inner wall of the mixing shell body 1; the connecting rod 25 passes through the mixing frame 6.

[0049] The operation process of this embodiment is as follows: Before using this device, first take out the positioning tube 10. The crushing blade 14 is fixed on the outside of the positioning tube 10. Align the mounting strip 11 on the inner wall of the positioning tube 10 with the mounting groove 9 on the surface of the mounting rod 8, and fit it onto the outside of the mounting rod 8 along the direction of the mounting groove 9. After the positioning tube 10 is properly adjusted, pass the screw through the threaded hole 13 on the surface of the mounting plate 12 and tighten it to ensure that the crushing blade 14 is firmly installed and to prevent it from loosening during operation. Then add the feed to be processed into the mixing shell body 1, cover the top of the mixing shell body 1 with the cover plate 2, and fix the cover plate 2 to the mixing shell body 1 with bolts to ensure that the cover plate 2 is sealed. The seal is good; the power supply to motor 3 is turned on, and motor 3 is started. The output shaft of motor 3 rotates stably through bearing 4, driving the transmission rod 5 and the outer stirring frame 6 to rotate synchronously. When the stirring frame 6 rotates, the mounting rods 8 on both sides of its internal crossbeam 7 rotate with the stirring frame 6, driving the crushing blade 14 on the outside of the positioning tube 10 to rotate at high speed, crushing the feed inside the stirring shell body 1; at the same time, the stirring rods 15 on the upper and lower sides of the crossbeam 7 rotate synchronously, stirring the feed, so that the feed is in full contact with the crushing blade 14, improving the uniformity of crushing. The cleaners 20 on both sides of the stirring frame 6 rotate with the stirring frame 6; the springs 24 inside the cleaners 20 are in operation. The connecting plate 23 applies a pushing force to the connecting rod 25, ensuring that the scraper 26 at one end of the connecting rod 25 remains in close contact with the inner wall of the mixing shell body 1, scraping off the feed adhering to the inner wall to prevent feed residue and ensure that the feed is fully crushed by the crushing blade 14. The feed crushed to the required particle size is screened through the filter screen 28 in the discharge trough 17 and falls into the receiving box 31 below, completing the processing. The limiting rod 16 at the bottom of the mixing frame 6 is rotatably connected to the inner wall of the limiting tube 19 in the center of the bottom support strip 18 of the mixing shell body 1, which can enhance the stability of the mixing frame 6 during rotation and prevent shaking. In this device, the mixing frame 6 is the crushing blade. The mounting carrier of 14 is connected to the output shaft of motor 3 via transmission rod 5, which can drive the crushing blade 14 to rotate to achieve feed crushing. At the same time, the mixing frame 6 and the crushing blade 14 adopt a detachable design. The crushing blade 14 is fixed on the positioning tube 10. The positioning tube 10 is matched and sleeved with the mounting groove 9 of the mounting rod 8 via the mounting strip 11, and is fixed by the threaded hole 13 and screws on the mounting plate 12. After the mixing is completed, the screws can be unscrewed, and the positioning tube 10 and the crushing blade 14 can be removed from the mounting rod 8 to facilitate the thorough cleaning of the feed residue on the surface of the crushing blade 14, and to avoid the accumulation of residual feed affecting subsequent use.
