Description

Technical Field

[0001] The invention relates to the technical field of fertilizer crushing agricultural machinery, in particular to a fertilizer crushing device and a use method thereof. Background Art

[0002] Fertilizer crushing equipment is an agricultural machinery equipment that crushes bulk fertilizer raw materials into fertilizer particles. When too much fertilizer is fed, a large amount of fertilizer will accumulate in the feed hopper, which is easy to cause blockage of the feed hopper.

[0003] When the feed hopper is clogged, it needs to be unblocked in time. The common unblocking method is to first stop the machine to ensure the safety of subsequent workers' unblocking actions; then the workers use tools to stir the fertilizer in the feed hopper so that the fertilizer in the feed hopper is fed downward to achieve unblocking.

[0004] In the above-mentioned dredging method, because it requires stopping the machine and workers to manually dredge, it not only increases the labor intensity of workers, but also reduces the crushing efficiency. In response to this, a mechanical dredging method has been developed.

[0005] For example, in the patent with the announcement number CN216093946U, "An organic fertilizer crusher" is disclosed. The patent is provided with a feed hopper and a drive motor on the top of the machine body, a slide seat is provided on one side of the feed hopper, a turntable is connected to the output end of the drive motor, one end of the connecting rod is movably connected to the turntable, the other end of the connecting rod is movably connected to the slide bar, the slide bar is slidably connected to the slide seat, the slide bar passes through the feed hopper, and a partition is provided at one end of the slide bar located in the feed hopper. When the drive motor is started, the drive motor drives the turntable to rotate, the turntable drives the slide bar to slide back and forth left and right through the connecting rod, and the slide bar drives the partition to move back and forth left and right, so that the fertilizer raw materials in the feed hopper are stirred, thereby preventing blockage during feeding.

[0006] Although the above-mentioned prior art can realize mechanical dredging of the feed hopper, once the dredging is completed, the fertilizer in the feed hopper cannot be interrupted from feeding downward. The crushing capacity of the crushing equipment for fertilizer has an upper limit. After the feed hopper is dredged, a large amount of fertilizer will enter the crushing equipment, which will increase the crushing pressure and reduce the crushing effect.

[0007] Therefore, how to prevent the feed hopper from being blocked and conveniently interrupt the downward feeding of the fertilizer in the feed hopper is a technical problem that needs to be solved at present. Summary of the invention

[0019] A method for using a fertilizer crushing device, based on the fertilizer crushing device;

[0020] The method for unclogging the feed hopper is as follows: start the driving mechanism, the driving mechanism drives the movable rod to move up and down, the movable rod drives the upper end of the umbrella leaf to move up and down, so that the top of the umbrella body moves up and down, and the taper of the umbrella body changes reciprocatingly. When the top of the umbrella body moves up and down, the top of the umbrella body pound the fertilizer in the feed hopper up and down to unblock it;

[0021] The method of interrupting the downward feeding of fertilizer in the feed hopper is as follows: when the movable rod moves down to the lowest position, the driving mechanism is closed, the top of the umbrella body moves down to the lowest position, the taper of the umbrella body is in the maximum state, the umbrella body blocks the connection position between the feed hopper and the crusher body, and the downward feeding of fertilizer in the feed hopper is interrupted.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, when feeding into the grinder body, the driving mechanism drives the movable rod to move up and down, so that the top of the umbrella body formed by all the leaves moves up and down, so that the top of the umbrella body can stir the fertilizer in the feed hopper up and down, so that the fertilizer in the feed hopper can be loosened and unblocked, which can prevent the feed hopper from being blocked and ensure the feeding stability.

[0024] When the crushing operation is carried out inside the crusher body, the driving mechanism can be closed when the taper of the umbrella body is at the maximum state. At this time, the umbrella body can block the connection position between the feed hopper and the crusher body, thereby interrupting the downward feeding of the fertilizer in the feed hopper, avoiding a large amount of fertilizer from entering the inside of the crusher body, avoiding increasing the crushing pressure, and being beneficial to ensuring the crushing effect.

[0025] In summary, the present invention can not only prevent the feed hopper from being blocked, but also facilitate the interruption of the downward feeding of the fertilizer in the feed hopper, thereby improving the flexibility of use.

[0026] 2. Because the two adjacent umbrella leaves in the umbrella body are overlapped up and down, and the two adjacent umbrella leaves are slidably matched, when the taper of the umbrella body changes reciprocatingly, the two adjacent umbrella leaves can scrape each other to scrape off the fertilizer particles splashed on the lower surface of the umbrella leaves, thereby realizing self-cleaning of the umbrella body and helping to reduce the labor intensity of cleaning and maintenance operations.

[0027] 3. Because the cam's distal end is provided with a counterweight, the cam's center of gravity is lower than the position of the rotating shaft. Therefore, after the drive motor is turned off at any time, the cam can always turn the cam's distal end to the bottom of the rotating shaft, so that the umbrella body blocks the connection between the feed hopper and the grinder body, interrupting the downward feeding of the fertilizer in the feed hopper. Therefore, the drive motor can be turned off at any time, and the fertilizer in the feed hopper can be interrupted from continuing to feed into the grinder body at any time, further improving the flexibility of use.

[0028] 4. When crushing fertilizer, the umbrella can be used to cover the connection between the feed hopper and the crusher body. The fertilizer particles raised inside the crusher body can be blocked by the umbrella, preventing the fertilizer particles from being raised into the outside air through the feed hopper, thereby reducing air pollution.

[0029] 5. Because the lower part of the filter is suspended in the air, when the crushing blade cuts and stirs the fertilizer caught by the filter, the stirred fertilizer drives the lower part of the filter to vibrate. When the filter vibrates, it can shake off the fertilizer particles in the filter holes of the filter, reducing the risk of filter blockage during the crushing process and improving the reliability of the crushing operation.

[0030] 6. When the filter screen vibrates, the filter screen can drive the anti-blocking rod to vibrate together. The anti-blocking rod can dredge the discharge hopper during the vibration process, so that the fertilizer particles in the discharge hopper can be discharged more smoothly, which is conducive to improving the discharge efficiency.

[0031] 7. When cleaning the filter, the driving mechanism can be used to drive the movable rod to move up and down reciprocatingly, so that the lower end of the umbrella body pushes the upper part of the filter back and forth, so that the upper part of the filter cooperates with the reset spring to vibrate back and forth. Under the action of vibration, the filter can vibrate the fertilizer particles on the surface of the filter and in the filter holes, thereby realizing self-cleaning of the filter without manual cleaning, which is conducive to reducing labor intensity.

[0032] 8. By setting the retaining frame, square column, rod sleeve, piston, guide pin and wave groove, when the crushing shaft rotates, the piston can be driven to move back and forth inside the crushing shaft, so that the outside air can be absorbed into the interior of the crushing shaft, and the air inside the crushing shaft can be pushed into the interior of the crusher body, so that the fertilizer being crushed can be stirred by air, so that the crushing blade can more comprehensively contact and crush the fertilizer particles in the raw material cavity, which is beneficial to improve the crushing efficiency.

[0033] 9. The reciprocating air supply action of the piston does not require the use of other power sources, but can be achieved only by the rotation of the crushing shaft, which is beneficial to saving energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Embodiment 1:

[0057] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A fertilizer crushing device comprises a crusher body 1, and a feed hopper 11 is fixedly installed on the top of the crusher body 1.

[0058] A dredging mechanism is provided inside the feed hopper 11 , and the dredging mechanism is used to dredge the feed hopper 11 .

[0059] See also Fig. 9 and Fig.10The dredging mechanism includes a fixed frame 21, a fixed cylinder 22, an umbrella rib rod 23, a slide seat 24, a movable rod 25, and an umbrella leaf 26. The fixed frame 21 is fixedly installed inside the pulverizer body 1. The fixed cylinder 22 is fixedly installed on the fixed frame 21. Four umbrella rib rods 23 are fixedly installed on the side wall of the fixed cylinder 22, and the four umbrella rib rods 23 are evenly distributed around the circumference of the fixed cylinder 22. The umbrella rib rod 23 is hinged with a slide seat 24 at one end away from the fixed cylinder 22. The inside of the fixed cylinder 22 is vertically slidably connected with a movable rod 25. Four umbrella leaves 26 are hinged on the top of the movable rod 25, and the number of umbrella leaves 26 is the same as the number of umbrella rib rods 23. All umbrella leaves 26 form an umbrella body, and two adjacent umbrella leaves 26 are overlapped up and down, and two adjacent umbrella leaves 26 are slidably matched. A slide rail 261 is fixedly installed on the bottom surface of the umbrella leaf 26, and the slide rail 261 is slidably connected with the slide seat 24. A conical cap 251 is provided on the top of the movable rod 25 . The conical cap 251 is arranged above the umbrella leaf 26 . The conical cap 251 is used to shield the gap between the umbrella leaf 26 and the movable rod 25 .

[0060] The feed hopper 11 is also provided with a driving mechanism, which is used to drive the movable rod 25 to move up and down.

[0061] See also Fig. 9 The driving mechanism includes a driving motor 31, a rotating shaft 32, and a cam 33. The driving motor 31 is fixedly mounted on the outside of the pulverizer body 1, and the rotating shaft 32 is arranged inside the pulverizer body 1. Both ends of the rotating shaft 32 are rotatably connected to the pulverizer body 1 through bearings, and one end of the rotating shaft 32 is fixedly connected to the output end of the driving motor 31. The cam 33 is fixedly mounted on the rotating shaft 32, and a closed slide groove 331 is provided on the end surface of the cam 33, and the shape of the closed slide groove 331 is the same as the peripheral shape of the cam 33. A bending portion 252 is provided at the lower end of the movable rod 25, and the bending portion 252 is slidably matched with the closed slide groove 331.

[0062] The working principle of this embodiment 1 is as follows:

[0063] (1) The method of unclogging the feed hopper 11 is as follows:

[0064] The driving motor 31 is started, the driving motor 31 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the cam 33 to rotate. Because the movable rod 25 can only slide up and down in the fixed cylinder 22, the bent portion 252 at the bottom of the movable rod 25 is located in the closed sliding groove 331 on the end surface of the cam 33, so every time the cam 33 rotates one circle, the groove wall of the closed sliding groove 331 pushes the bent portion 252 to move up and down once, and the bent portion 252 drives the movable rod 25 to move up and down once.

[0065] Specifically, when the distal end of the cam 33 rotates to the top of the rotating shaft 32, the groove wall of the closed sliding groove 331 lifts the bent portion 252 to the highest position, and the bent portion 252 drives the movable rod 25 to the highest position. When the distal end of the cam 33 rotates to the bottom of the rotating shaft 32, the proximal end of the cam 33 is located above the rotating shaft 32, and the groove wall of the closed sliding groove 331 pushes the bent portion 252 to the lowest position, and the bent portion 252 drives the movable rod 25 to the lowest position.

[0066] When the movable rod 25 moves up and down, the movable rod 25 drives the upper ends of all the umbrella leaves 26 to move up and down together, so that the top of the umbrella body surrounded by all the umbrella leaves 26 also moves up and down, and the taper of the umbrella body also changes reciprocatingly.

[0067] Specifically, when the movable rod 25 is at the highest position, the top of the umbrella is at the highest position, the taper of the umbrella is at the minimum state, and the side slope of the umbrella is at the steepest state. At this time, the top of the umbrella is inserted into the fertilizer to the maximum depth, the width of the channel formed between the side of the umbrella and the inner wall of the feed hopper 11 is the largest, and the flow rate of the fertilizer feeding downward is the largest. When the movable rod 25 is at the lowest position, the top of the umbrella is at the lowest position, the taper of the umbrella is at the maximum state, that is, the side slope of the umbrella is at the gentlest state. At this time, the top of the umbrella is inserted into the fertilizer to the minimum depth, and the umbrella blocks the connection position between the feed hopper 11 and the crusher body 1, interrupting the downward feeding of the fertilizer in the feed hopper 11.

[0068] Because the top of the umbrella body can reciprocate up and down, the top of the umbrella body can stir the fertilizer in the feed hopper 11 up and down, so that the fertilizer in the feed hopper 11 is unblocked. Because the taper of the umbrella body reciprocates between the maximum and the minimum, the fertilizer in the feed hopper 11 can intermittently enter the inside of the pulverizer body 1, so as to realize the feeding into the inside of the pulverizer body 1.

[0069] (2) The method for interrupting the downward feeding of fertilizer in the feed hopper 11 is as follows:

[0070] When the movable rod 25 moves down to the lowest position, the top of the umbrella body moves down to the lowest position, the taper of the umbrella body is at the maximum state, and the umbrella body blocks the connection position between the feed hopper 11 and the crusher body 1. At this time, the drive motor 31 can be turned off. Figure 3 , the umbrella body can interrupt the downward feeding of the fertilizer in the feed hopper 11.

[0071] According to the above working principle of the present embodiment 1, it can be known that the present embodiment 1 has the following effects:

[0072] In this embodiment 1, when feeding into the grinder body 1, the driving mechanism drives the movable rod 25 to move up and down, so that the top of the umbrella body formed by all the umbrella leaves 26 moves up and down, so that the top of the umbrella body can stir the fertilizer in the feed hopper 11 up and down, so that the fertilizer in the feed hopper 11 is loosened and unblocked, which can prevent the feed hopper 11 from being blocked and ensure the stability of feeding.

[0073] In this embodiment 1, when the crushing operation is carried out inside the crusher body 1, the driving mechanism can be closed when the taper of the umbrella body is at the maximum state. At this time, the umbrella body can block the connection position between the feed hopper 11 and the crusher body 1, and the downward feeding of the fertilizer in the feed hopper 11 can be interrupted, thereby avoiding a large amount of fertilizer from entering the inside of the crusher body 1 and avoiding increasing the crushing pressure, which is beneficial to ensuring the crushing effect.

[0074] In summary, the present embodiment 1 can not only prevent the feed hopper 11 from being blocked, but also facilitates the interruption of the downward feeding of the fertilizer in the feed hopper 11, thereby improving the flexibility of use.

[0075] Because two adjacent umbrella leaves 26 in the umbrella body are overlapped up and down and slide together, when the taper of the umbrella body changes back and forth, the two adjacent umbrella leaves 26 can scrape each other to scrape off the fertilizer particles splashed onto the lower surface of the umbrella leaves 26, thereby realizing self-cleaning of the umbrella body and reducing the labor intensity of cleaning and maintenance operations.

[0076] Embodiment 2:

[0077] In Example 1, the cam 33 is fixedly mounted on the rotating shaft 32, and the rotating shaft 32 drives the cam 33 to rotate together. When the umbrella body is used to shield the connection position between the feed hopper 11 and the crusher body 1, the worker needs to promptly shut down the drive motor 31 in the drive mechanism when the movable rod 25 moves down to the lowest position. Because it is difficult to control the timing of moving the movable rod 25 to the lowest position, it is difficult to control the timing of shutting down the drive motor 31.

[0078] In order to reduce the difficulty of controlling the timing, this embodiment 2 is further improved on the basis of embodiment 1:

[0079] See also Fig.11 , Fig.12 , Fig.13 , Fig.14 The cam 33 is provided with a rotation hole 332 at the center position, and the rotation hole 332 is rotatably matched with the rotating shaft 32. A first abutment block 333 is fixedly installed on the end surface of the cam 33, and the first abutment block 333 is arranged at the proximal end of the cam 33. A second abutment block 321 is fixedly installed on the side of the rotating shaft 32, and the second abutment block 321 is used to abut against the first abutment block 333. A counterweight block 334 is fixedly installed on the distal end of the cam 33.

[0080] The working principle of this embodiment 2 is as follows:

[0081] (1) The method of unclogging the feed hopper 11 is as follows:

[0082] Start the drive motor 31, and the drive motor 31 drives the rotating shaft 32 to rotate. When the second abutment block 321 on the rotating shaft 32 abuts against the first abutment block 333 on the end face of the cam 33, the rotating shaft 32 can push the cam 33 to rotate together through the second abutment block 321 and the first abutment block 333. Every time the cam 33 rotates one circle, the movable rod 25 moves back and forth once, the top of the umbrella body moves back and forth once, and the taper of the umbrella body changes back and forth once. When the top of the umbrella body moves back and forth up and down, the fertilizer in the feed hopper 11 can be pounded up and down, so that the fertilizer in the feed hopper 11 is unblocked. When the taper of the umbrella body changes back and forth between the maximum and the minimum, the fertilizer in the feed hopper 11 can intermittently enter the inside of the crusher body 1 to realize the feeding into the crusher body 1.

[0083] (2) The method for interrupting the downward feeding of fertilizer in the feed hopper 11 is as follows:

[0084] Turn off the drive motor 31 and the shaft 32 stops rotating. Since a counterweight 334 is installed on the distal end of the cam 33, the center of gravity of the cam 33 is lower than the position of the shaft 32. Therefore, after the shaft 32 stops rotating, the cam 33 continues to rotate around the shaft 32 until the center of gravity of the cam 33 is directly below the shaft 32. At this time, the distal end of the cam 33 is directly below the shaft 32, so that the movable rod 25 is in the lowest position, the top of the umbrella body moves down to the lowest position, the taper of the umbrella body is in the maximum state, and the umbrella body blocks the connection position between the feed hopper 11 and the crusher body 1, interrupting the downward feeding of the fertilizer in the feed hopper 11.

[0085] According to the above working principle of the present embodiment 2, it can be known that the present embodiment 2 has the following effects:

[0086] In the second embodiment, since the distal end of the cam 33 is provided with a counterweight 334, the center of gravity of the cam 33 is lower than the position of the rotating shaft 32. Therefore, after the driving motor 31 is turned off at any time, the cam 33 can always rotate the distal end of the cam 33 to the position directly below the rotating shaft 32, so that the umbrella body blocks the connection position between the feed hopper 11 and the crusher body 1, interrupting the downward feeding of the fertilizer in the feed hopper 11. Therefore, the driving motor 31 can be turned off at any time, and the feeding of the fertilizer in the feed hopper 11 into the crusher body 1 can be interrupted at any time, further improving the flexibility of use.

Figure 2 and Figure 4 The power mechanism includes a power motor 61, a main pulley 62, a secondary pulley 63, and a belt 64. The power motor 61 is fixedly mounted on the outside of the pulverizer body 1, the output end of the power motor 61 is fixedly mounted with a main pulley 62, the secondary pulley 63 is fixedly mounted on one end of the pulverizing shaft 51, and the main pulley 62 is driven by the secondary pulley 63 through the belt 64.

[0094] The working principle of this embodiment 3 is as follows:

[0095] (1) The working principle of crushed fertilizer is as follows:

[0096] First, the driving motor 31 is turned off to interrupt the downward feeding of the fertilizer in the feed hopper 11. Then, the power motor 61 is started, the power motor 61 drives the main pulley 62 to rotate, the main pulley 62 transmits the power to the secondary pulley 63 through the belt 64, the secondary pulley 63 drives the crushing shaft 51 to rotate, the crushing shaft 51 drives the crushing blade 52 to rotate together, the crushing blade 52 cuts the fertilizer entering the raw material chamber, the fertilizer particles crushed by the crushing blade 52 enter the crushing chamber through the filter screen 4, and the fertilizer particles entering the crushing chamber can be discharged through the discharge hopper 12.

[0097] When the crushing shaft 51 and the crushing blade 52 rotate, the raised fertilizer particles can be shielded by the umbrella body, preventing the fertilizer particles from being raised into the external air through the feed hopper 11, thereby reducing air pollution.

[0098] When the crushing shaft 51 and the crushing blade 52 rotate, the fertilizer caught by the filter screen 4 can be stirred. Since the lower part of the filter screen 4 is suspended, the filter screen 4 vibrates when the fertilizer is stirred. When the filter screen 4 vibrates, the filter screen 4 can drive the anti-blocking rod 43 to vibrate together. The anti-blocking rod 43 can clear the discharge hopper 12 during the vibration process, so that the fertilizer particles in the discharge hopper 12 can be discharged more smoothly, which is conducive to improving the discharge efficiency.

[0099] Furthermore, when the filter screen 4 vibrates, the fertilizer particles in the filter holes of the filter screen 4 can be shaken off, thereby reducing the risk of clogging of the filter screen 4 during the crushing process and improving the reliability of the crushing operation.

[0100] (2) The working principle of cleaning the filter 4 is as follows:

[0101] First, all the fertilizers in the feed hopper 11 are fed into the raw material chamber, and the crushing blades 52 crush all the fertilizers into fertilizer particles, and the fertilizer particles are all discharged from the discharge hopper 12, so that the materials inside the crusher body 1 are emptied.

[0102] Then, the driving motor 31 is started, and the driving motor 31 drives the movable rod 25 to move up and down reciprocatingly, and the movable rod 25 drives the top of the umbrella body to move up and down reciprocatingly, the taper of the umbrella body changes reciprocatingly, and the lower end of the umbrella body reciprocates to push the upper inner wall of the filter screen 4; whenever the taper of the umbrella body becomes larger, the lower end of the umbrella body can push the upper inner wall of the filter screen 4, so that the upper part of the filter screen 4 overcomes the elastic force of the return spring 42 and moves to both sides; whenever the taper of the umbrella body becomes smaller, the lower end of the umbrella body leaves the upper inner wall of the filter screen 4, and the upper part of the filter screen 4 approaches the middle under the elastic force of the return spring 42; thus, whenever the lower end of the umbrella body reciprocates to push the upper inner wall of the filter screen 4, the upper part of the filter screen 4 reciprocates between moving to both sides and approaching the middle, and the lower part of the filter screen 4 is suspended again, so the filter screen 4 is vibrated, and under the vibration, the surface of the filter screen 4 and the fertilizer particles in the filter holes can be vibrated down, so that the filter screen 4 is self-cleaned without manual cleaning.

[0103] According to the above working principle of the present embodiment 3, it can be known that the present embodiment 3 has the following effects:

[0104] In this embodiment 3, when crushing fertilizer, an umbrella can be used to cover the connection position between the feed hopper 11 and the crusher body 1. The fertilizer particles raised inside the crusher body 1 can be blocked by the umbrella, preventing the fertilizer particles from being raised into the external air through the feed hopper 11, thereby reducing air pollution.

[0105] In the present embodiment 3, because the lower part of the filter screen 4 is suspended in the air, when the crushing blade 52 cuts and stirs the fertilizer caught by the filter screen 4, the stirred fertilizer drives the lower part of the filter screen 4 to vibrate. When the filter screen 4 vibrates, it can shake off the fertilizer particles in the filter holes of the filter screen 4, thereby reducing the risk of clogging of the filter screen 4 during the crushing process and improving the reliability of the crushing operation.

[0106] In the present embodiment 3, when the filter screen 4 vibrates, the filter screen 4 can drive the anti-blocking rod 43 to vibrate together. The anti-blocking rod 43 can clear the discharge hopper 12 during the vibration process, so that the fertilizer particles in the discharge hopper 12 can be discharged more smoothly, which is beneficial to improve the discharge efficiency.

[0107] In the present embodiment 3, when cleaning the filter 4, the movable rod 25 can be driven by the driving mechanism to move up and down reciprocatingly, so that the lower end of the umbrella body pushes the upper part of the filter 4 reciprocatingly, so that the upper part of the filter 4 cooperates with the reset spring 42 to vibrate reciprocatingly. Under the action of vibration, the filter 4 can vibrate the fertilizer particles on the surface of the filter 4 and in the filter holes, thereby realizing self-cleaning of the filter 4 without manual cleaning, which is conducive to reducing labor intensity.

[0108] Embodiment 4:

[0109] This embodiment 4 is further improved on the basis of embodiment 3:

[0110] See also Figure 6 The crushing shaft 51 is a hollow shaft. A one-way air intake structure is installed at one end of the crushing shaft 51, and the one-way air intake structure can use a one-way air intake valve 511. A plurality of one-way air outlet structures are installed on the side of the crushing shaft 51, and the one-way air outlet structure can use a one-way air outlet valve 512.

[0111] See also Figure 6The crushing mechanism also includes a retaining frame 53, a square column 54, a rod sleeve 55, a piston 56, and a guide pin 57. The retaining frame 53 is arranged at one end of the crushing shaft 51 away from the one-way air intake valve 511, and the retaining frame 53 is fixedly connected to the outside of the crusher body 1. The retaining frame 53 is fixedly mounted with a square column 54. The square column 54 is sleeved with a rod sleeve 55, and the rod sleeve 55 is slidably connected to the square column 54 along the axial direction of the crushing shaft 51. The rod sleeve 55 is fixedly mounted with a piston 56, and the piston 56 is slidably matched with the inside of the crushing shaft 51. The side wall of the rod sleeve 55 is fixedly mounted with a guide pin 57, and the inner wall of the crushing shaft 51 is provided with a wave groove 513 connected from head to tail, and the guide pin 57 is slidably matched with the wave groove 513.

[0112] The working principle of the present embodiment 4 crushed fertilizer is as follows:

[0113] First, the driving motor 31 is turned off to interrupt the downward feeding of the fertilizer in the feed hopper 11. Then, the power motor 61 is started, the power motor 61 drives the main pulley 62 to rotate, the main pulley 62 transmits the power to the secondary pulley 63 through the belt 64, the secondary pulley 63 drives the crushing shaft 51 to rotate, the crushing shaft 51 drives the crushing blade 52 to rotate together, the crushing blade 52 cuts the fertilizer entering the raw material chamber, the fertilizer particles crushed by the crushing blade 52 enter the crushing chamber through the filter screen 4, and the fertilizer particles entering the crushing chamber can be discharged through the discharge hopper 12.

[0114] During the rotation of the crushing shaft 51 , the wave groove 513 on the inner wall of the crushing shaft 51 rotates with the crushing shaft 51 . Since the rod sleeve 55 inside the crushing shaft 51 can only move axially, the guide pin 57 on the rod sleeve 55 slides relative to the wave groove 513 .

[0115] Specifically, when the guide pin 57 is located at the trough of the wave groove 513, the rod sleeve 55 enters the interior of the crushing shaft 51 to the shallowest depth, the piston 56 is located at the shallowest depth inside the crushing shaft 51, and the air pressure in the internal space of the crushing shaft 51 in front of the piston 56 is reduced, and the external air can be sucked into the interior of the crushing shaft 51 through the one-way air inlet valve 511; when the guide pin 57 is located at the crest of the wave groove 513, the rod sleeve 55 enters the interior of the crushing shaft 51 to the greatest depth, the piston 56 is located at the greatest depth inside the crushing shaft 51, and the piston 56 pushes the air inside the crushing shaft 51 out of the one-way air outlet valve 512.

[0116] Thus, during the rotation of the crushing shaft 51, external air continuously enters the interior of the crushing shaft 51, and the air inside the crushing shaft 51 is discharged through the one-way air outlet valve 512. The air discharged from the one-way air outlet valve 512 is blown toward the raw material chamber, which can help stir the fertilizer particles in the raw material chamber, allowing the crushing blade 52 to more comprehensively contact and crush the fertilizer particles in the raw material chamber, which is beneficial to improving the crushing efficiency.

[0117] According to the above working principle of the present embodiment 4, it can be known that the present embodiment 4 has the following effects:

[0118] By arranging the retaining frame 53, the square column 54, the rod sleeve 55, the piston 56, the guide pin 57, and the wave groove 513, when the crushing shaft 51 rotates, the piston 56 can be driven to reciprocate inside the crushing shaft 51, so that the outside air can be absorbed into the inside of the crushing shaft 51, and the air inside the crushing shaft 51 can be pushed into the inside of the crusher body 1, so that the fertilizer being crushed can be stirred by air, so that the crushing blade 52 can more comprehensively contact and crush the fertilizer particles in the raw material cavity, which is beneficial to improving the crushing efficiency.

[0119] Furthermore, the reciprocating air supplying action of the piston 56 can be realized by the rotation of the crushing shaft 51 without using other power sources, which is beneficial to saving energy.

[0120] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
