Description

Technical Field

[0001] This invention relates to the field of organic fertilizer production technology, specifically to an environmentally friendly pulverizing device for bio-organic fertilizer. Background Technology

[0002] The bio-organic fertilizer crushing device is a key piece of equipment used for crushing bio-organic fertilizers. It plays an important role in the production process of organic fertilizers. The bio-organic fertilizer crushing device is a mechanical device specifically designed for crushing bio-organic fertilizers. It can effectively crush bio-organic fertilizers to the required particle size for subsequent processing and use. Depending on the crushing method and principle, bio-organic fertilizer crushing devices can be divided into several types, such as blade crushers and disc crushers.

[0003] The patent titled "A Fertilizer Crushing Device for Organic Fertilizer Production," publication number CN110732390B, addresses existing crushing devices that require granulation after organic fertilizer crushing. These devices often require fertilizers of varying crushing degrees to produce particles of different sizes. Conventional crushing devices are inconvenient for adjusting the crushing degree, and they tend to generate significant dust during crushing. Furthermore, they are not ideal for humidifying excessively dry fertilizer to reduce dust generation. This new device, however, incorporates a transmission structure that adjusts the distance between the crushing blades and the outer barrel wall. By pressing down a hydraulic rod, the rotating plate is pushed outwards, thereby adjusting the crushing effect. A connecting groove is provided on the inner inclined surface of the device, allowing water to be slowly added to the inside through the top of the device. The water can flow from the top layer of the connecting groove to the bottom layer, preventing the fertilizer from drying out too much and causing dust to rise. However, in actual use, it was found that during the crushing process, the crushing blades are connected to the outer and inner barrels respectively. The outer and inner barrels are movable and there are no other positioning structures, which causes significant shaking during the crushing process. Under such significant shaking, the distance between the inner and outer barrels will constantly change, resulting in poor effect in adjusting the particle size of the crushed fertilizer. Therefore, an environmentally friendly crushing device for bio-organic fertilizer is proposed. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1, such as Figure 1 As shown, this application discloses an environmentally friendly pulverizing device for bio-organic fertilizer, comprising an L-shaped support base 100, a hydraulic cylinder 103 fixedly connected to the outside of the L-shaped support base 100, a drive motor 104 fixedly connected to the piston rod end of the hydraulic cylinder 103, a connecting rod 105 fixedly connected to the output shaft of the drive motor 104, a pulverizing roller 106 fixedly connected to the end of the connecting rod 105 away from the drive motor 104, two arc-shaped support plates 101 movably connected to the L-shaped support base 100, a pulverizing chamber 102 fixedly connected to the arc-shaped support plate 101, the two pulverizing chambers 102 being hinged together, the pulverizing chamber 102 enclosing the pulverizing roller 106, inclined cutters connected to the inner wall of the pulverizing chamber 102 and the outside of the pulverizing roller 106, the cross-sections of the pulverizing chamber 102 and the pulverizing roller 106 being rhomboid, and a pressure regulating structure installed inside the pulverizing chamber 102 and the pulverizing roller 106.

[0029] Specifically, during use, the operator can throw the organic fertilizer material to be crushed into the feed inlet of the crushing chamber 102. When the organic fertilizer material is relatively raw, the operator can activate the hydraulic cylinder 103 to drive the drive motor 104 and the crushing roller 106 downwards, thereby increasing the space at the feed inlet of the crushing chamber 102 and allowing the material to be smoothly fed into the crushing chamber 102. When the material enters the crushing chamber 102, the operator can activate the drive motor 104. During the activation of the drive motor 104, the crushing roller 106 can be rotated via the connecting rod 105. During the rotation of the crushing roller 106, the material located between the crushing roller 106 and the crushing chamber 102 can be crushed by the inclined cutter.

[0030] Furthermore, during the material crushing process, the operator can intermittently activate the hydraulic cylinder 103 to drive the crushing roller 106 to move up and down inside the crushing chamber 102. As the crushing roller 106 moves upward, it gradually comes into contact with the inner wall of the crushing chamber 102. When the crushing roller 106 comes into contact with the inner wall of the crushing chamber 102, it will gradually compress the material. As the material is gradually compressed and is cut by the tilting cutter driven by the rotating crushing roller 106, the material can be further crushed into smaller particles. When it is only necessary to cut the material into larger particles, the hydraulic cylinder 103 can be activated again to drive the connecting rod 105 and the crushing roller 106 to move downward inside the crushing chamber 102, which can increase the distance between the material and the crushing chamber 102 and reduce the phenomenon of the material being crushed into smaller particles.

[0031] Furthermore, during the material crushing process, the cross-sections of the crushing chamber 102 and the crushing roller 106 are rhomboid. When the crushing roller 106 moves upward to cooperate with the crushing chamber 102 to reduce the material crushing space, the crushing space below the crushing roller 106 and below the crushing chamber 102 will increase accordingly, allowing more material to flow out of the interior of the crushing chamber 102 quickly. When the material flows out of the bottom of the crushing chamber 102, it will also be crushed again, increasing the crushing stroke and reducing the phenomenon of material not being crushed in time.

[0032] like Figure 1 As shown, the bottom of the arc-shaped support plate 101 is integrally formed with a magnetic seat 600. The magnetic seat 600 is used to attach to the L-shaped support base 100, thereby fixing the arc-shaped support plate 101 to the L-shaped support base 100. Multiple fixing plates 700 are fixedly connected to the outside of the arc-shaped support plate 101. Multiple threaded holes are opened on the outside of both the fixing plates 700 and the L-shaped support base 100, and bolts are threaded inside the threaded holes.

[0033] Specifically, during use, the two grinding chambers 102 are supported by two arc-shaped support plates 101. During installation, the arc-shaped support plates 101 are fixed to the L-shaped support base 100 by fixing plates 700 and bolts. In order to maintain the stability of the arc-shaped support plates 101 on the L-shaped support base 100 when they are not fixed, the arc-shaped support plates 101 can be attracted to the L-shaped support base 100 by magnetic base 600.

[0034] like Figure 1 and Figure 2 As shown, both grinding chambers 102 are externally connected to buckles 500.

[0035] Specifically, during use, the two crushing chambers 102 are hinged together, and the two hinged crushing chambers 102 can be connected by buckles 500 to ensure the stability of the two crushing chambers 102 during the crushing process. When crushing fertilizer is not required, the two buckles 500 can be opened to remove the fixation of the arc-shaped support plate 101, and the two crushing chambers 102 can be separated by the staff, which facilitates the internal inspection and cleaning of the two crushing chambers 102. The overall structure is simpler and more convenient.

[0036] like Figure 7 As shown, the crushing chamber 102 is fitted with two separate feed hoppers 400. One separate feed hopper 400 has multiple insertion holes 402 on its exterior, and the other separate feed hopper 400 has multiple insertion rods 401 integrally formed on its exterior. The insertion rods 401 are inserted into the interior of the insertion holes 402.

[0037] Specifically, during the feeding process, the two separate feeding hoppers 400 can be connected to the inside of the insertion hole 402 through the insertion rod 401, so that the separate feeding hoppers 400 form a complete feeding funnel and can be easily snapped onto the crushing chamber 102.

[0038] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, the adjustment between the crushing chamber 102 and the crushing roller 106 is not achieved through a linkage structure. During the overall adjustment process, the crushing roller 106 and the crushing chamber 102 are relatively independent. Therefore, it is more stable during the rotation and cutting of materials, and there will be no excessive shaking. In addition, while adjusting the cutting fineness, the feed rate and cutting stroke can be controlled by the crushing chamber 102 and the crushing roller 106 with a diamond-shaped cut surface, thereby increasing the cutting time and further increasing the crushing effect of organic fertilizer.

[0039] Example 2: Considering that during the material crushing process, although the diamond-shaped crushing chamber 102 and crushing roller 106 can increase the material cutting stroke, in processes requiring finer material cutting, a single material cutting may not meet the fine cutting requirements. Furthermore, after the material is cut inside the crushing chamber 102, it gradually accumulates at the bottom of the crushing chamber 102 due to gravity, affecting the cutting condition of the crushing chamber 102. To address the above technical problems, this application proposes the following technical solution:

[0040] like Figures 2-3As shown, both the crushing chamber 102 and the crushing roller 106 are divided into an upper crushing section and a lower crushing section. The inclined cutter includes multiple upper spiral cutter groups 107 and multiple lower spiral cutter groups 108. The multiple upper spiral cutter groups 107 are respectively connected to the inner wall of the crushing chamber 102 in the upper crushing section and the outside of the crushing roller 106. The multiple lower spiral cutter groups 108 are respectively connected to the inner wall of the crushing chamber 102 in the lower crushing section and the outside of the crushing roller 106. The upper spiral cutter groups 107 are located above the lower spiral cutter groups 108.

[0041] Specifically, when the drive motor 104 drives the connecting rod 105 and the crushing roller 106 to rotate, the multiple upper spiral cutter groups 107 in the upper crushing section of the crushing roller 106 and the crushing chamber 102 are spirally downward. As the material enters the crushing chamber 102 and comes into contact with the crushing roller 106, the multiple spiral cutter groups 107 spirally downward cut and transport the material downward. As the material gradually spirals downward and accumulates below the crushing chamber 102, the multiple lower spiral cutter groups 108 in the lower crushing section of the crushing roller 106 and the upper spiral cutter groups 107 spirally cut and transport the material upward. Overall, the material is continuously spirally transported and cut inside the crushing chamber 102, reducing the accumulation of material at the bottom of the crushing chamber 102. A manual or electric discharge device (not shown in the figure) can be installed at the discharge port at the bottom of the crushing chamber 102. When the material is cut to a specified degree, the manual or electric discharge device is opened to transport the material to the outside.

[0042] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, after the material passes through the cutting above the crushing roller 106, the material will gradually accumulate to the bottom of the crushing chamber 102 due to gravity. The upper spiral cutter group 107 and the lower spiral cutter group 108 can move the material fed into the crushing chamber 102 downwards for cutting. After moving downwards for cutting, the material will move upwards again for cutting. Overall, the material does not accumulate at the bottom of the crushing chamber 102 due to gravity, but is cut multiple times while rising and falling, avoiding the phenomenon of material accumulating inside the crushing chamber 102 and affecting the cutting.

[0043] Example 3: Considering that although the upper spiral cutter assembly 107 and the lower spiral cutter assembly 108 can allow fertilizer to remain in the crushing chamber 102 for a longer time, thus increasing the crushing time and further improving the crushing effect, the upward-sloping lower spiral cutter assembly 108, under continuous rotation, will affect the discharge speed. Furthermore, even when the crushing roller 106 stops rotating, some fertilizer will still remain inside the crushing chamber 102. To address these technical problems, this application proposes an air pressure regulating structure to solve them, specifically:

[0044] like Figures 3-8 As shown, the air pressure regulating structure includes a bidirectional air pump 200, which is fixedly connected to the outer wall of the L-shaped support 100. Multiple elastic rubber seats 210 are integrally formed on the inner wall of the crushing chamber 102 and the outer wall of the crushing roller 106. The upper spiral cutter assembly 107 and the lower spiral cutter assembly 108 are both fixedly connected inside the elastic rubber seats 210. A placement cavity is integrally formed inside the crushing roller 106. The air outlet of the bidirectional air pump 200 is connected to a diversion box 201. A first conveying pipe 202 is connected to the outside of the diversion box 201. A rotating annular sleeve 205 is connected to the end of the first conveying pipe 202 away from the diversion box 201. The rotating annular sleeve 205 is rotatably connected to... An air inlet is provided on the outside of the connecting rod 105, which is connected to the rotating annular sleeve 205. An air delivery groove 206 is provided inside the connecting rod 105, which is connected to the air inlet. A diversion pipe 207 is fixedly connected inside the crushing roller 106, which is connected to the air delivery groove 206. Two diversion solenoid valves 208 are installed on the outside of the diversion pipe 207. The air outlets of the two diversion solenoid valves 208 are connected to a through hose. The ends of the two through hoses away from the diversion solenoid valves 208 are connected to a second annular push airbag 2011, which is located inside the placement cavity of the crushing roller 106.

[0045] like Figures 3-8 As shown, the air pressure regulating structure also includes a second conveying pipe 203 and a third conveying pipe 204. Both the second conveying pipe 203 and the third conveying pipe 204 are connected to the outside of the diversion box 201. The crushing chamber 102 has an integrally formed accommodating cavity. Two first annular pushing airbags 209 are fixedly connected inside the accommodating cavity. One first annular pushing airbag 209 is located at the feed inlet of the crushing chamber 102, and the other first annular pushing airbag 209 is located at the discharge outlet of the crushing chamber 102. The end of the second conveying pipe 203 away from the diversion box 201 is connected to the first annular pushing airbag 209 at the feed inlet, and the end of the third conveying pipe 204 away from the diversion box 201 is connected to the first annular pushing airbag 209 at the discharge outlet.

[0046] Specifically, during use, when feeding is required, the operator can start the bidirectional air pump 200 to continuously inject gas into the diversion box 201. While continuously injecting gas into the diversion box 201, the gas is continuously diverted through the diversion box 201 to the first conveying pipe 202. As the gas continues to flow into the first conveying pipe 202, it continuously enters the rotating annular sleeve 205. The rotating annular sleeve 205 then diverts the gas to the air inlet of the connecting rod 105. As the gas enters the air inlet of the connecting rod 105, it gradually enters the gas delivery groove 206. Once inside the gas delivery groove 206, the gas is delivered... The channel 206 delivers gas to the inside of the diversion pipe 207. Inside the diversion pipe 207, the gas is diverted by two diversion solenoid valves 208. During this diversion process, the two solenoid valves 208 can deliver gas to the inside of the through hose. The through hose can then divert the externally delivered gas to the inside of the second annular push airbag 2011. The second annular push airbag 2011 consists of two parts, one above and one below the cavity. The upper diversion solenoid valve 208 delivers gas to the upper second annular push airbag 2011. When the second annular push airbag 2011 delivers gas through the diversion solenoid valve 208 and the through hose, the inside of the second annular push airbag 2011 expands. When the second annular pushing airbag 2011 expands, it continuously pushes the upper spiral cutter group 107 and the lower spiral cutter group 108 located outside the crushing roller 106 to tilt. When the first annular pushing airbag 209 expands, it continuously pushes the upper spiral cutter group 107 and the lower spiral cutter group 108 located on the inner wall of the crushing chamber 102 to tilt. In use, gas can also be supplied to the two first annular pushing airbags 209 inside the cavity of the crushing chamber 102 through the second conveying pipe 203 and the third conveying pipe 204, causing the two first annular pushing airbags 209 inside the cavity to expand as well. When the first annular pushing airbags 209 expand, they also push the upper spiral cutter group 107 and the lower spiral cutter group 108 located on the inner wall of the crushing chamber 102 to tilt. The upper spiral cutter assembly 107 and the lower spiral cutter assembly 108 on the wall are tilted. They are connected by an elastic rubber seat 210. When pushed by the first annular pushing airbag 209 and the second annular pushing airbag 2011, the elastic rubber seat 210 deforms, causing the upper spiral cutter assembly 107 and the lower spiral cutter assembly 108 to tilt. By controlling the tilt angle of the upper spiral cutter assembly 107 and the lower spiral cutter assembly 108, the tilt angle of the upper spiral cutter assembly 107 and the lower spiral cutter assembly 108 can be controlled during the crushing process. When the lower spiral cutter assembly 108 is fully tilted upwards or fully tilted downwards and in contact with the outer wall of the crushing roller 106 and the inner wall of the crushing chamber 102,...The reduced contact between the lower spiral cutter assembly 108 and the material being crushed allows the material to be less obstructed by the spiral lift provided by the lower spiral cutter assembly 108, thus enabling the material to be quickly discharged from the crushing chamber 102.

[0047] Furthermore, during the crushing process, the degree of crushing can be controlled by actively controlling the tilting direction of the upper spiral cutter group 107 and the lower spiral cutter group 108. In addition, when gas is further delivered into the first annular pushing airbag 209 and the second annular pushing airbag 2011, the upper spiral cutter group 107 and the lower spiral cutter group 108 can be pushed forward, which can further increase the degree of crushing of fertilizer.

[0048] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, by continuously supplying gas into the interior of the first annular pushing airbag 209 and the second annular pushing airbag 2011, the upper spiral cutter group 107 and the lower spiral cutter group 108 can be tilted. When the upper spiral cutter group 107 and the lower spiral cutter group 108 are tilted, the organic fertilizer can be crushed under different conditions. In the crushing process, by adjusting the direction of the upper spiral cutter group 107 and the lower spiral cutter group 108, the crushed feed can be actively pushed downward, reducing the phenomenon of feed remaining on the upper spiral cutter group 107 and the lower spiral cutter group 108. At the same time, by adjusting the angle of the upper spiral cutter group 107 and the lower spiral cutter group 108, the phenomenon of organic fertilizer being blocked by the spiral lower spiral cutter group 108 and unable to be discharged smoothly can be solved.

[0049] Example 4: Considering that the second annular thrust airbag 2011 and the first annular thrust airbag 209 may be blocked by the upper spiral cutter group 107 and the lower spiral cutter group 108 when inflated, preventing them from fully inflating, and being stuck at a certain position by one of the upper spiral cutter groups 107 and the lower spiral cutter group 108, the second annular thrust airbag 2011 and the first annular thrust airbag 209 cannot fully inflate when blocked by the upper spiral cutter group 107 and the lower spiral cutter group 108, that is, they cannot drive the remaining upper spiral cutter groups 107 and the lower spiral cutter groups 108 to change direction, this application proposes the following technical solution to solve the above technical problem, specifically:

[0050] like Figure 8 As shown, the expansion ends of the second annular pushing airbag 2011 and the first annular pushing airbag 209 are both integrally formed with fixed adsorption electromagnets 301, and multi-segment tilting electromagnets 300 are fixedly connected at the middle positions of the crushing roller 106 placement cavity and the crushing chamber 102 accommodating cavity.

[0051] Specifically, during use, to prevent the upper spiral cutter assembly 107 and the lower spiral cutter assembly 108 from obstructing the expansion stroke of the second annular pushing airbag 2011 and the first annular pushing airbag 209 in their initial state, a fixed adsorption electromagnet 301 is provided. This fixed electromagnet 301 can continuously push the fixed adsorption electromagnet 301 to move as the second annular pushing airbag 2011 and the first annular pushing airbag 209 expand. During the movement of the fixed adsorption electromagnet 301, its rigid inclined surface can first push the upper spiral cutter assembly 107 and the lower spiral cutter assembly 108 to tilt. During the movement of the fixed adsorption electromagnet 301, the rigid inclined surface... The fixed adsorption electromagnet 301 reduces the jamming phenomenon of the upper spiral cutter group 107 and the lower spiral cutter group 108 on the front end of the soft second annular push airbag 2011 and the first annular push airbag 209. Furthermore, through the multi-segment tilting electromagnet 300 fixedly connected at the middle position, the multi-segment tilting electromagnet 300 can be activated to adsorb the fixed adsorption electromagnet 301 when it is pushed by the expanded second annular push airbag 2011 and the first annular push airbag 209. This continuous adsorption allows the fixed adsorption electromagnet 301 to move, preventing it from being jammed and providing a dragging force for the fixed adsorption electromagnet 301 to move in the expansion direction.

[0052] Furthermore, when the second annular pushing airbag 2011 and the first annular pushing airbag 209 contract, in order to avoid the upper spiral cutter group 107 and the lower spiral cutter group 108 causing jamming with the fixed adsorption electromagnet 301 in the opposite direction, the fixed adsorption electromagnet 301 can be activated when the second annular pushing airbag 2011 and the first annular pushing airbag 209 contract, so that the fixed adsorption electromagnet 301 is adsorbed on the inner wall surface of the placement cavity and the accommodating cavity, thereby reducing the phenomenon of the upper spiral cutter group 107 and the lower spiral cutter group 108 jamming with the fixed adsorption electromagnet 301 in the opposite direction when the fixed adsorption electromagnet 301 moves in the opposite direction.

[0053] like Figure 9 As shown, the first annular push airbag 209 has an integrally formed inclined fan-shaped nozzle 800 on its outside. The air outlet of the inclined fan-shaped nozzle 800 penetrates the outer wall of the crushing chamber 102, and the air outlet of the inclined fan-shaped nozzle 800 is inclined downward.

[0054] Specifically, during use, when the first annular pushing airbag 209 expands, the inclined fan-shaped nozzle 800 can be opened. The inclined fan-shaped nozzle 800 can spray the gas inside the first annular pushing airbag 209 into the feed inlet of the crushing chamber 102 in a fan shape, thereby forming an air wall at the feed inlet of the crushing chamber 102. The formed air wall reduces the dust generated during the crushing of organic fertilizer, thus enhancing environmental protection.

[0055] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 3, in this embodiment, the fixed adsorption electromagnet 301 can actively push the upper spiral cutter group 107 and the lower spiral cutter group 108 to tilt when the second annular push airbag 2011 and the first annular push airbag 209 expand. The fixed adsorption electromagnet 301 assists the second annular push airbag 2011 and the first annular push airbag 209 to move smoothly downward when expanded, thereby enabling smooth auxiliary adjustment of multiple upper spiral cutter groups 107 and lower spiral cutter groups 108. This avoids the phenomenon that the second annular push airbag 2011 and the first annular push airbag 209 are blocked by an upper spiral cutter group 107 and the lower spiral cutter group 108 at a certain position, thus preventing the adjustment of the remaining upper spiral cutter groups 107 and lower spiral cutter groups 108.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
