Description

Technical Field

[0001] This invention belongs to the field of feed production technology, and in particular relates to a device for crushing and mixing biological feed raw materials. Background Technology

[0002] A biological feed ingredient crushing and mixing device is a piece of equipment used in the feed production process. It is mainly used to crush and mix the raw materials for biological feed to facilitate subsequent shaping, fermentation, or other processing. This device is receiving increasing attention in modern animal husbandry, especially in the formulation of nutritionally balanced feeds.

[0003] Currently, existing double-roller crushing mechanisms generally lack online cleaning functions. When crushing high-moisture, high-sugar, and high-fiber biological feeds, the roller surface is prone to material sticking, which leads to a reduction in the effective meshing area, a decrease in crushing efficiency, and secondary extrusion of the sticky material to form "hard strips". This material is mixed into the finished product, affecting the uniformity of subsequent fermentation. Frequent manual scraping and cleaning by stopping the machine is required, which is labor-intensive and poses a risk of dust explosion.

[0004] Therefore, we propose a biological feed ingredient crushing and mixing device. Summary of the Invention

[0025] like Figures 1-9 As shown, an embodiment of the present invention provides a biological feed raw material crushing and mixing device, including a support frame 1 and a crushing component 2 and a mixing component 3 disposed on the upper surface of the support frame 1. The crushing component 2 and the mixing component 3 are connected by a connecting pipe 4. The crushing component 2 includes a crushing box 21 disposed on the upper surface of the support frame 1 and a crushing wheel 22 disposed inside the crushing box 21. There are two crushing wheels 22, and the two crushing wheels 22 are positioned corresponding to each other. A cleaning component 26 is disposed below the two crushing wheels 22. The cleaning component 26 is used to clean the debris on the crushing wheels 22 and can clean itself. The mixing component 3 includes a fixed seat 31 disposed on the support frame 1, and a mixing box 32 is disposed on the upper surface of the fixed seat 31.

[0026] It should be noted that the lower end face of the crushing box 21 is provided with a discharge port, one end of the connecting pipe 4 is connected to the discharge port, one end of the mixing box 32 is provided with a feed port, the other end of the connecting pipe 4 is pressed against the mixing box 32, and the position of the connecting pipe 4 pressed against the mixing box 32 corresponds to that of the feed port.

[0027] The cleaning assembly 26 includes a large gear 261 disposed at one end of the crushing wheel 22 and a small gear 262 disposed on the side below the large gear 261. The small gear 262 located on the side below the large gear 261 meshes with the large gear 261. A bidirectional screw 263 is disposed on the large gear 261. The end of the bidirectional screw 263 away from the large gear 261 is rotatably connected to the inner wall of the crushing box 21.

[0028] A guide block 264 is provided on one side below the bidirectional screw 263. A movable plate 265 is threadedly connected to the bidirectional screw 263. The guide block 264 on one side below the bidirectional screw 263 passes through the movable plate 265. A cleaning brush 266 is provided at one end of the movable plate 265. One end of the cleaning brush 266 presses against the crushing wheel 22. A first guide plate 267 is provided below both bidirectional screws 263. A second guide plate 268 is provided on both sides of the top inner side of the crushing box 21.

[0029] It should be noted that both the first guide plate 267 and the second guide plate 268 are elastic plates, and one end of the first guide plate 267 and the second guide plate 268 are connected to the inner wall of the crushing box 21.

[0030] During the operation of the crushing wheel 22, the chain drive of the large gear 261, small gear 262, and bidirectional screw 263 causes the moving plate 265 to drive the cleaning brush 266 to reciprocate along the wheel surface. The brush bristles peel off the fibrous and greasy debris adhering to the wheel teeth and grooves in real time, avoiding the "sticking" phenomenon, maintaining a constant wheel tooth meshing gap, and ensuring the uniformity of the crushed particle size. At the same time, it reduces the additional power consumption and temperature rise caused by secondary extrusion of debris.

[0031] The two second guide plates 268 and the two first guide plates 267 are arranged in a figure-eight shape. A vibration knocking assembly is provided on the pinion 262. The vibration knocking assembly includes a fixing ring 2621 on the pinion 262, a fixing rod 2622 on the fixing ring 2621, a limit socket 2623 at one end of the fixing rod 2622, a helical spring 2624 at the bottom inner side of the limit socket 2623, and a vibration knocking plate 2625 inserted inside the limit socket 2623. The cross-section of the end of the vibration knocking plate 2625 away from the fixing rod 2622 is arc-shaped.

[0032] The pinion 262 simultaneously drives the fixed ring 2621, the fixed rod 2622, and the vibrating tapping plate 2625 to rotate. When the arc end of the vibrating tapping plate 2625 strikes the first guide plate 267, the plate surface generates elastic high-frequency micro-vibration, which continuously loosens and removes the damp powder and grease layer attached to the plate surface, and slides down the V-shaped slope to the discharge port, avoiding the phenomena of "bridging" and "arching". The compression-reset process of the helical spring 2624 absorbs excessive impact, which not only protects the tapping plate itself, but also keeps the vibration frequency or amplitude in the optimal cleaning range, achieving continuous, gentle, and low-noise self-cleaning of the plate surface.

[0033] The movable plate 265 is provided with an auxiliary cleaning component, which includes a fixed box 2651 disposed on both sides of the movable plate 265. A fixed wheel 2652 is rotatably disposed inside the fixed box 2651. The fixed wheel 2652 passes through the fixed box 2651 and presses against the guide block 264. A first bevel gear 2653 is disposed on the fixed wheel 2652.

[0034] The two side walls of the movable plate 265 are rotatably provided with first synchronous wheels 2655. The two first synchronous wheels 2655 are respectively located inside the two fixed boxes 2651. The first synchronous wheels 2655 are connected to the second bevel gear 2654 through the fixed shaft. The second bevel gear 2654 meshes with the first bevel gear 2653.

[0035] A second synchronous wheel 2656 is rotatably disposed above the first synchronous wheel 2655 on the movable plate 265. The second synchronous wheel 2656 is hollow. A synchronous belt 2658 connects the first synchronous wheel 2655 and the second synchronous wheel 2656. The bidirectional screw 263 passes through the first synchronous wheel 2655 on the movable plate 265. A cleaning ring 2657 is provided on the inner wall of the second synchronous wheel 2656, and the cleaning ring 2657 presses against the bidirectional screw 263 passing through the second synchronous wheel 2656.

[0036] When the moving plate 265 moves, the fixed wheel 2652 rolls on the guide block 264, driving the first bevel gear 2653, the second bevel gear 2654, the first synchronous pulley 2655, the synchronous belt 2658, the second synchronous pulley 2656, and the cleaning ring 2657 to rotate. The spiral cutting edge on the inner wall of the cleaning ring 2657 performs double scraping of the thread groove of the bidirectional screw 263 by "rotation + axial sliding", continuously discharging the powder falling into the screw outward, preventing the thread from being "filled" and causing the moving plate 265 to jam, ensuring that the reciprocating stroke of the cleaning brush 266 is always accurate, and extending the trouble-free cycle of the screw-nut pair.

[0037] The crushing box 21 is equipped with a first drive motor 23. The output end of the first drive motor 23 is connected to a crushing wheel 22. Two transmission gears 24 are rotatably arranged on one side wall of the crushing box 21. The two transmission gears 24 mesh with each other and are respectively connected to the two crushing wheels 22. The upper end face of the crushing box 21 is equipped with a feed hopper 25.

[0038] The upper end face of the fixed base 31 is provided with multiple limiting grooves at equal intervals. The outer wall surface of the mixing box 32 is provided with multiple limiting rings 33. The multiple limiting rings 33 on the mixing box 32 are slidably connected in the multiple limiting grooves on the fixed base 31. A fixing frame 34 is provided on one side of the fixed base 31. The fixing frame 34 is mounted on the support frame 1.

[0039] The fixed frame 34 is provided with a second drive motor 37, the mixing box 32 is fitted with a second gear 36, the fixed frame 34 is provided with a first gear 35, the output end of the second drive motor 37 is connected to the first gear 35, and the second gear 36 meshes with the first gear 35.

[0040] Inside the crushing box 21, the second guide plate 268 concentrates the feed and directs it to the double-wheel meshing area, while the first guide plate 267 guides the shaken-fallen material to the discharge port, forming a closed loop of "feeding-crushing-cleaning-shaking-discharging". The connecting pipe 4 directly introduces the crushed material into the rotatable mixing box 32. The second drive motor 37 drives the first gear 35, the second gear 36, and the mixing box 32 to rotate at a low speed. The spiral ribs on the inner wall of the box repeatedly lift, scatter, and axially propel the material, realizing a continuous process of "crushing and mixing at the same time", reducing intermediate transfer links and lowering the risk of cross-contamination.

[0041] Working principle: The first drive motor 23 drives the crushing wheel 22, which in turn rotates. The crushing wheel 22 drives the transmission gear 24, which in turn rotates. The meshing of the transmission gear 24 causes the two crushing wheels 22 to rotate relative to each other. The raw material is then fed into the crushing box 21 through the feed hopper 25. Under the guidance of the second guide plate 268, the raw material in the crushing box 21 is concentrated between the two crushing wheels 22. The raw material falling between the two crushing wheels 22 is crushed. During the rotation of the crushing wheel 22, it drives the large gear 261 mounted on it to rotate. The large gear 261 drives the small gear 262, which meshes with it, to rotate. The small gear 262 drives the bidirectional screw 263 to move back and forth along the guide block 264. 263 drives the moving plate 265 to move, and the moving plate 265 drives the cleaning brush 266 to move on the crushing wheel 22. The cleaning brush 266 cleans the residual debris on the crushing wheel 22. As the moving plate 265 moves, the fixed wheel 2652, which presses against the guide block 264, rotates with the movement. The fixed wheel 2652 drives the first bevel gear 2653 to rotate, and the first bevel gear 2653 drives the second bevel gear 2654 to rotate. The second bevel gear 2654 drives the first synchronous pulley 2655 to rotate through the fixed shaft. The first synchronous pulley 2655 drives the second synchronous pulley 2656 to rotate through the synchronous belt 2658. The second synchronous pulley 2656 drives the cleaning ring 2657 to rotate. The rotation of 2657 cleans impurities and debris from the bidirectional screw 263 through which the second synchronous pulley 2656 passes. Simultaneously, the pinion 262 rotates, driving the fixed ring 2621 mounted on it to rotate. The fixed ring 2621 drives the fixed rod 2622 to rotate, which in turn drives the vibrating tapping plate 2625 to rotate. When one end of the vibrating tapping plate 2625 rotates to the first guide plate 267, and the end of the vibrating tapping plate 2625 away from the fixed rod 2622 presses against and strikes the vibrating tapping plate 2625, the vibrating tapping plate 2625 vibrates. If the force of the vibrating tapping plate 2625 pressing against and striking the vibrating tapping plate 2625 is too great, the vibrating tapping plate 2625 will apply the excess force to the fixed rod 2625. The helical spring 2624 inside 622 is compressed under force to prevent the vibrating striking plate 2625 from being damaged due to excessive force. The first guide plate 267 can guide the debris falling from the pinion 262 to the discharge port of the crushing box 21. The raw material discharged from the crushing box 21 will be transported to the mixing box 32 through the connecting pipe 4. At the same time, the second drive motor 37 is started, which drives the first gear 35 to rotate. The second gear 36 meshed with the first gear 35 rotates, and the second gear 36 drives the mixing box 32 to rotate. During the rotation, the mixing box 32 mixes the raw material inside and transports the mixed raw material to one side and sends the raw material out of the mixing box 32.
