Description

Technical Field

[0001] The invention belongs to the field of agricultural fertilizer production, and in particular relates to a crushing device for agricultural organic fertilizer production. Background Art

[0002] Organic fertilizers have many benefits in agriculture and horticulture, which not only help to increase crop yields and quality, but also improve soil health and environmental sustainability. In the process of producing organic fertilizers, many raw materials need to be crushed to improve their decomposition efficiency, mixing uniformity and the quality of the final product. Among them, the more common raw materials for making organic fertilizers include animal manure, plant residues and kitchen waste.

[0003] At present, the treatment of kitchen waste usually involves first sorting the waste, then dehydrating the waste that can be converted into organic fertilizer, and then sending it to a crushing device for crushing. Since the composition of kitchen waste is relatively complex, even after the waste is sorted, there will still be some other waste that has not been completely sorted and removed, such as plastic bags or packaging bags. After entering the crushing device, these wastes are easily entangled on the crushing roller of the crushing equipment. The internal space of the existing crushing equipment shell is narrow, especially for multi-stage crushing equipment, there is a problem of difficulty in cleaning.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-10 The present application is further described in detail.

[0032] Please refer to Figure 1-Figure 9 A crushing device for producing agricultural organic fertilizers includes a base 1, and the upper part of the base 1 is provided with three groups of crushing mechanisms 2 that are sequentially connected from top to bottom. The crushing mechanism 2 includes an outer shell 21 with an open structure at the top and bottom, a stepped groove 211 is provided at the upper open port of the outer shell 21, and a plug-in end 212 matching the stepped groove 211 is fixedly connected to the lower side of the outer shell 21, and the corresponding stepped grooves 211 in the three outer shells 21 are slidably plugged with the plug-in end 212, and a connecting seat 5 is fixedly provided on the upper part of the base 1, and a slot matching the plug-in end 212 is provided on the connecting seat 5, and the plug-in end 212 on the lower side of the lower outer shell 21 is slidably plugged into the slot. An inclined support seat with a triangular structure is fixedly provided on the left and right side walls of the lower outer shell 21, and the inclined support seat is fixedly connected to the base 1 by bolts, and a lower bin is provided at the middle position of the upper side of the base 1. Two symmetrical fixing rods 22 are fixedly arranged inside the outer shell 21, and a blanking plate 23 is rotatably arranged on the fixing rods 22. Sliding components 24 are arranged on the front and rear side walls of the outer shell 21. Two symmetrical crushing rollers 25 are rotatably connected between the two corresponding front and rear sliding components 24, and a supporting component 26 for supporting the blanking plate 23 is arranged on the sliding component 24. A toggle block 4 that cooperates with the supporting component 26 to drive the blanking plate 23 to shake is fixedly arranged on the front and rear end side walls of the crushing roller 25.

[0033] In order to improve the crushing quality of fertilizer raw materials, the distance between the two crushing rollers 25 is adjusted by the sliding component 24, so that the distance between the two corresponding crushing rollers 25 in the three groups of crushing mechanisms 2 is reduced from top to bottom, so as to realize multi-stage continuous crushing and ensure the crushing quality. At the same time, the sliding component 24 can cooperate with the supporting component 26. When the sliding component 24 moves, it synchronously drives the supporting component 26 to move. The supporting component 26 can drive the corresponding unloading plate 23 to rotate around the fixed rod 22. While adjusting the distance between the corresponding two crushing rollers 25, the inclination angle of the two corresponding unloading plates 23 above can also be adjusted accordingly, so as to adjust the size of the unloading opening formed between the two unloading plates 23, so that when the distance between the two adjacent crushing rollers 25 is reduced, the unloading opening formed by the two corresponding unloading plates 23 above is reduced synchronously, so as to avoid the fertilizer falling too quickly and accumulating between the two crushing rollers 25 to affect the crushing quality, thereby further improving the crushing quality of the fertilizer.

[0034] See also Figure 6 and Figure 7 The front and rear side walls of the outer shell 21 are provided with through holes in a strip-shaped structure. The sliding assembly 24 includes a screw rod 241 rotatably arranged between the left and right side walls of the through hole. The two ends of the screw rod 241 are provided with threaded sections with opposite thread directions and the two threaded sections are threadedly connected with sliders 242. The crushing roller 25 is rotatably arranged between the corresponding front and rear sliders 242. The left side wall of the outer shell 21 is rotatably provided with two handles 243 symmetrically arranged in front and back. The left end of the screw rod 241 is fixedly connected to the corresponding handle 243. The screw rod 241 is rotated by rotating the front and rear handles 243 at the same time by manual or external driving source, so that the two sliders 242 on the screw rod 241 move toward each other, and the corresponding two crushing rollers 25 are controlled to approach or move away from each other, and the distance between the two is adjusted as needed.

[0035] See also Figure 8 and Fig. 9The support assembly 26 includes a mounting frame 261 with a U-shaped structure, and the mounting frame 261 is fixedly connected to the corresponding slider 242 through a connecting column 264. The horizontal section of the mounting frame 261 is slidably connected with a first slide column 262, and the upper end of the first slide column 262 is slidably inserted with a second slide column 263. The upper end of the second slide column 263 movably contacts the lower side wall of the blanking plate 23. A locking bolt is threadedly provided on the side wall of the first slide column 262 near the upper end, and a plurality of locking holes matching the locking bolts are provided on the surface of the second slide column 263. Stop blocks 265 are fixedly provided on the left and right side walls near the upper end of the first slide column 262, and the stop blocks 265 movably contact the upper side wall of the horizontal section of the mounting frame 261. A lifting block 266 with an arc-shaped structure is fixedly provided at the lower end of the first sliding column 262, and the toggle block 4 is set to an arc-shaped structure. A plurality of guide rollers evenly distributed along the center direction of the circle are rotatably provided on the outer arc surface of the toggle block 4. The guide rollers roll against the arc surface of the lifting block 266, and the friction when the lifting block 266 and the toggle block 4 contact is reduced by the guide rollers. Two left-right symmetrical springs 267 are fixedly provided on the lower side wall of the horizontal section of the mounting frame 261, and the lower end of the spring 267 is fixedly connected to the corresponding lifting block 266.

[0036] In order to reduce the risk of the fertilizer raw material adhering to the upper side wall of the unloading plate 23 when unloading, the second sliding post 263 is in active contact with the lower side of the unloading plate 23. When the slider 242 on the sliding assembly 24 moves, it can drive the second sliding post 263 to move left and right, so that the second sliding post 263 can slide left and right to drive the unloading plate 23 to rotate around the fixed rod 22, thereby adjusting the inclination angle of the unloading plate 23. At the same time, the second sliding post 263 and the first sliding post 262 can slide relative to each other and be fixed by a locking bolt. When the second sliding post 263 moves upward to increase the height, the second sliding post 263 can also The unloading plate 23 is driven to rotate around the fixed rod 22, so that the inclination angle of the unloading plate 23 changes, and the size of the unloading opening formed between the two corresponding unloading plates 23 is changed. At the same time, when the crushing roller 25 rotates, it will drive the toggle block 4 to rotate synchronously. When the toggle block 4 rotates, it will cyclically conflict with the arc surface of the lifting block 266, driving the lifting block 266 to move upward, driving the first sliding column 262 and the second sliding column 263 to move upward, so that the second sliding column 263 can continuously push the unloading plate 23 with a small amplitude, causing the unloading plate 23 to shake cyclically, thereby promoting the movement of fertilizer on the unloading plate 23.

[0037] See also Figure 1 , Figure 4 , Figure 5 and Fig.10The locking mechanism 3 includes a first sleeve 31, a first limit block 32 is slidably disposed inside the first sleeve 31, a second sleeve 33 is fixedly connected to the upper side of the first limit block 32, a second limit block 34 is slidably connected inside the second sleeve 33, a locking rod 35 is fixedly connected to the upper side of the second limit block 34, two front-to-back symmetrical ear plates 36 are fixedly disposed on the left and right side walls of the three outer shells 21, the lower end of the first sleeve 31 is fixedly connected to the lowermost corresponding ear plate 36, and the upper ends of the second sleeve 33 and the second sleeve 33 are respectively threadedly connected to the adjacent ear plates 36. The first sleeve 31 is movably connected to the second sleeve 33, and the second sleeve 33 is movably connected to the locking rod 35. The first sleeve 31 and the second sleeve 33 both have movable cavities formed therein, the first limit block 32 and the second limit block 34 are slidably disposed in the corresponding movable cavities respectively, the upper ends of the first sleeve 31 and the second sleeve 33 both have sliding holes connected to the corresponding movable cavities, the second sleeve 33 is slidably disposed in the sliding hole at the upper end of the first sleeve 31, and the locking rod 35 is movably disposed in the sliding hole at the upper end of the second sleeve 33.

[0038] In order to facilitate the cleaning of the crushing mechanism 2, the outer shells 21 on the three crushing mechanisms 2 are locked by the locking mechanism 3. Before installation, the second sleeve 33 is retracted in the first sleeve 31, and the locking rod 35 is retracted in the second sleeve 33. During installation, when the three outer shells 21 are plugged in sequence, the first sleeve 31 is fixed on the lowermost outer shell 21, and the second sleeve 33 is pushed upward so that the upper end of the second sleeve 33 abuts against the corresponding ear plate 36 on the side wall of the middle outer shell 21, and then the second sleeve 33 is rotated forward so that the second sleeve 33 and the ear plate 36 are locked. The second sleeve 33 is threadedly connected, and the second sleeve 33 is continuously rotated forwardly, so that the first limit block 32 finally abuts against the upper side of the internal active cavity of the first sleeve 31. At this time, the second sleeve 33 and the first sleeve 31 interact with each other to generate a tensioning force, and then the locking rod 35 is pulled upward, so that the upper end of the locking rod 35 abuts against the corresponding ear plate 36 on the side wall of the uppermost outer shell 21, and then the locking rod 35 is rotated forwardly again, so that the locking rod 35 is threadedly connected with the ear plate 36, and the locking rod 35 is continuously rotated forwardly, so that the second limit block 34 finally abuts against the inner active cavity of the second sleeve 33. The second sleeve 33 and the locking rod 35 interact with each other to generate a tensioning force, thereby fastening the three outer shells 21 together to ensure stability. When the crushing roller 25 inside the outer shell 21 needs to be cleaned, the locking rod 35 can be rotated in the opposite direction to separate the locking rod 35 from the ear plate 36 on the side wall of the uppermost outer shell 21, so that the middle outer shell 21 no longer limits the uppermost outer shell 21, which facilitates the removal of the uppermost outer shell 21. Similarly, the second sleeve 33 is then reversed to make the lowermost outer shell 2 1 no longer limits the position of the middle outer shell 21, so that the middle outer shell 21 can also be removed, so that the three crushing mechanisms 2 originally fixed together can be separately disassembled, which is convenient for cleaning the inside of the crushing mechanism 2. At the same time, the staff can manually rotate the unloading plate 23 to make the unloading plate 23 rotate counterclockwise, so that the unloading plate 23 no longer blocks the crushing roller 25, which is more convenient for cleaning the crushing roller 25. When cleaning, the two crushing rollers 25 can also be separated from each other by the sliding assembly 24, which is further convenient for cleaning the crushing roller 25.

[0039] See also Figure 1 , Figure 6 , Figure 7 and Figure 8The front end of the crushing roller 25 is fixedly connected with a first bevel gear 6, and a first connecting plate is fixedly arranged on the front side wall of the slider 242 located on the front side of the outer shell 21. The first connecting plate is rotatably connected with a second bevel gear 7 through a rotating shaft, and the second bevel gear 7 is meshed with the first bevel gear 6. A second connecting plate is fixedly arranged on the front side wall of the outer shell 21, and a connecting shaft 8 is rotatably arranged on the second connecting plate. The connecting shaft 8 and the two second bevel gears 7 are slidably connected by spline matching. The connecting shaft 8 can drive the two second bevel gears 7 to rotate at the same time, and the crushing roller 25 rotates in cooperation with the first bevel gear 6, and the second bevel gear 7 can slide along the length direction of the connecting shaft 8. When the two sliders 242 on the sliding assembly 24 move, the corresponding first bevel gear 6 and second bevel gear 7 can follow the movement.

[0040] See also Figure 2 , Figure 6 and Figure 7 A third connecting plate is fixedly provided at a position near the left end of each connecting shaft 8 on the front side wall of the outer shell 21, and a first connecting rod 9 is rotatably provided on the third connecting plate. A third bevel gear 10 is fixedly provided on the left end of the connecting shaft 8, and a fourth bevel gear 11 meshing with the adjacent third bevel gear 10 is fixedly provided on the surface of the first connecting rod 9 close to the third bevel gear 10. The lower ends of the two first connecting rods 9 except the lowest first connecting rod 9 are fixedly connected with a rectangular block 12, and the upper ends of the two first connecting rods 9 except the uppermost first connecting rod 9 are fixedly connected with a second connecting rod 13, and the upper end of the second connecting rod 13 is fixedly provided with a holder 14, and a slot matching the block 12 is opened on the upper side of the holder 14, and the block 12 is slidably inserted in the corresponding slot. A driving motor is fixedly provided on the lower side wall of the third connecting plate at the lowest point through the fourth connecting plate, and the output shaft of the driving motor is fixedly connected to the lower end of the lowest first connecting rod 9. When the three outer shells 21 are fixed, the slot on the upper end of the second connecting rod 13 and the corresponding block 12 at the lower end of the first connecting rod 9 are inserted, so that the first connecting rod 9 can drive the second connecting rod 13 to rotate. During operation, the driving motor drives the bottom first connecting rod 9 to rotate, so that the bottom fourth bevel gear 11 rotates the bottom connecting shaft 8 with the cooperation of the corresponding third bevel gear 10, driving the bottom two crushing rollers 25 to rotate, and at the same time, the bottom first connecting rod 9 rotates the other two connecting shafts 8 at the same time through the two second connecting rods 13, so that the three connecting shafts 8 can rotate at the same time to drive the crushing rollers 25 inside the corresponding outer shell 21 to rotate and crush the fertilizer raw materials.

[0041] See also Figure 4 , Figure 5 and Figure 7Two symmetrical connecting ports are provided on the left and right side walls of the two outer shells 21 except the lowermost outer shell 21. The connecting ports are connected to the interior of the outer shell 21. A slide 15 is slidably arranged in the connecting port. A pull rod 16 is rotatably arranged on the side of the slide 15 close to the interior of the outer shell 21. A hook 17 is fixedly arranged on the end of the pull rod 16 away from the slide 15. The hook 17 is hooked with a nearby fixed rod 22. A rotating rod 18 is rotatably arranged on the side of the slide 15 away from the pull rod 16. A U-shaped fixing frame 19 is threadedly connected to the rotating rod 18. The fixing frame 19 is fixedly arranged on the outer wall of the outer shell 21.

[0042] In order to further improve the stability of the three outer shells 21 after installation, when the three outer shells 21 are connected, the top rotating rod 18 is rotated forward to drive the corresponding slide seat 15 to move outward, thereby pulling the pull rod 16 to move, so that the hook 17 at the lower end of the pull rod 16 can approach the fixed rod 22 on the same side of the middle outer shell 21, and finally the hook 17 is hooked with the fixed rod 22, so that the top outer shell 21 and the middle outer shell 21 are further locked by the connection between the pull rod 16 and the fixed rod 22, and the middle outer shell 21 and the bottom outer shell 21 are locked by the same method, so as to further improve the stability between the outer shells 21. When disassembling the outer shell 21 later, it is only necessary to rotate the rotating rod 18 in the opposite direction to separate the hook 17 from the corresponding fixed rod 22.

[0043] During specific operation, the spacing between the two crushing rollers 25 inside each outer shell 21 is adjusted by the sliding assembly 24, so that the spacing between the three groups of crushing rollers 25 is reduced from top to bottom in sequence. At the same time, the sliding assembly 24 also cooperates with the supporting assembly 26 to automatically drive the unloading plate 23 above the crushing roller 25 to rotate, so that the unloading port formed by the two corresponding unloading plates 23 on the left and right can be expanded or reduced synchronously. The fertilizer raw material falls from the top port of the outer shell 21 and falls on the unloading plate 23, and then slides along the unloading plate 23 to between the two top crushing rollers 25. At the same time, the driving motor drives the three connecting shafts 8 to rotate, so that the crushing roller 25 can rotate to crush the fertilizer raw material, and the fertilizer raw material is crushed step by step from top to bottom. During the rotation process, the crushing roller 25 can also drive the toggle block 4 to rotate. The rotation of the toggle block 4 can cooperate with the supporting assembly 26 to drive the unloading plate 23 to vibrate slightly, so as to avoid adhesion between the fertilizer raw material and the unloading plate 23 and hinder unloading.

[0044] When it is necessary to clean the crushing roller 25, the locking rod 35 and the second sleeve 33 are rotated in sequence, so that the locking rod 35 and the second sleeve 33 are retracted into the first sleeve 31, and the limit between the three outer shells 21 of the locking mechanism 3 is released. Then the rotating rod 18 is rotated in the opposite direction to make the slide seat 15 slide toward the inside of the outer shell 21. During the sliding process, the hook 17 originally connected with the fixing rod 22 will gradually move away from the fixing rod 22 and finally separate from the fixing rod 22. After that, the two upper outer shells 21 can be lifted off the lowermost outer shell 21, so that the three outer shells 21 are separated from each other, and then the blanking plate 23 is rotated in the opposite direction to expose the crushing roller 25. At the same time, the corresponding two crushing rollers 25 are separated by controlling the sliding assembly 24 through the manual reverse rotation handle 243, so as to facilitate the cleaning of the crushing roller 25.
