Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, and in particular to an organic fertilizer raw material grinding device. Background Technology

[0002] Organic fertilizer refers to fertilizer made primarily from animal excrement or plant and animal remains rich in organic matter, which is fermented and decomposed. It is characterized by its variety, wide availability, and long-lasting effects. During the production of organic fertilizer, the raw materials need to be ground and pulverized to improve fermentation efficiency.

[0003] Chinese utility model patent CN212284369U discloses a grinding device for processing organic fertilizer raw materials, including a grinding box, a driving device, and a mounting groove. The grinding box has a grinding chamber with a grinding plate at its bottom and multiple perforations. An inclined sliding plate is located within the grinding box, and a driving box is located at its top. A feeding port is located on one side of the top of the grinding chamber. The driving device includes a flywheel, a rotating rod, and a sliding rod. The flywheel is rotatably connected to the driving box via a rotating shaft. The flywheel is rotatably connected to the upper end of the rotating rod, and the lower end of the rotating rod is rotatably connected to the top end of the sliding rod. A grinding head is fixedly connected to the lower end of the sliding rod. The mounting groove is located within the grinding box, and a lead screw is rotatably connected to it. A threaded seat is threaded onto the lead screw, and a roller frame is located at the bottom of the threaded seat. A grinding roller is rotatably connected to the roller frame via a rotating shaft. This grinding device further crushes the raw material through two grinding processes, resulting in more thorough grinding and improved grinding efficiency.

[0004] The grinding device disclosed in the aforementioned utility model patent involves feeding raw materials into a grinding chamber. A motor drives a grinding head to move and press and grind the raw materials within the chamber. The ground materials then fall onto a sliding plate, where a motor drives a rolling roller to further crush the materials. In essence, this grinding device uses a grinding head and rolling rollers to press and crush the raw materials separately, resulting in a complex structure that is inconvenient for later inspection and maintenance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an organic fertilizer raw material grinding device, which solves the problems of complex structure and inconvenience in later inspection and maintenance of existing grinding devices.

[0006] According to an embodiment of this utility model, an organic fertilizer raw material grinding device includes a shell with a accommodating cavity, a grinding cylinder is provided in the accommodating cavity and a plurality of through holes are provided on the grinding cylinder at intervals, the shell is also provided with a liftable movable plate and a drive assembly that is pulsatorically connected to the movable plate, the movable plate is located above the grinding cylinder, a limiting frame is provided on the side of the movable plate near the grinding cylinder, a grinding head is provided in the limiting frame and the grinding head can move vertically or rotate around the vertical direction within the limiting frame, a connecting rod is provided between the movable plate and the grinding head, the two ends of the connecting rod are respectively provided with spherical heads, and the sides of the movable plate and the grinding head that are close to each other are respectively provided with connecting seats that correspond to the spherical heads. When the drive assembly drives the movable plate to move closer to or away from the grinding cylinder, the grinding head extends into or retracts from the grinding cylinder, and when the grinding head completely retracts from the grinding cylinder, the distance between the grinding head and the grinding cylinder is less than the stroke of the movable plate when it moves vertically downward under the drive assembly.

[0007] Furthermore, the bottom of the housing is provided with a discharge pipe communicating with the accommodating cavity, and the discharge pipe is provided with a discharge valve.

[0008] Furthermore, the bottom of the accommodating cavity is provided with a guide surface, which surrounds the discharge pipe and the height of the guide surface increases in the direction away from the discharge pipe.

[0009] Furthermore, the housing is also provided with a mounting bracket, on which two vertical guide grooves are spaced apart, and the two ends of the movable plate extend into the guide grooves respectively.

[0010] Furthermore, the drive assembly includes a motor mounted on the mounting bracket, a rocker arm mounted at the output end of the motor, and a transmission rod rotatably connected to the rocker arm, wherein the end of the transmission rod away from the rocker arm is rotatably connected to the movable plate.

[0011] Furthermore, the side of the grinding head away from the grinding cylinder has a limiting plate. The limiting frame includes a plurality of limiting rods spaced apart along the circumference of the grinding head, and the end of the limiting rod away from the movable plate has a bent portion. The limiting rods are respectively attached to the outer peripheral wall of the limiting plate, and the bent portion abuts against the side of the limiting plate away from the movable plate.

[0012] Furthermore, a rotatable limiting ring is fitted onto the limiting disc, and the diameter of the limiting ring is larger than the diameter of the opening of the grinding cylinder.

[0013] Furthermore, the grinding head has a plurality of protruding ridges on the side near the grinding cylinder, and the plurality of protruding ridges are spaced apart along the circumference of the grinding head.

[0014] Furthermore, at least three connecting rods are provided between the movable plate and the grinding head, and the connecting rods are equally spaced along the circumference of the grinding head.

[0015] Furthermore, the connecting seat includes a fixedly connected seat body and a cover body, the seat body and the cover body forming a spherical groove for accommodating the spherical head, and the cover body is provided with a through hole communicating with the spherical groove.

[0016] Compared with existing technologies, this utility model has the following advantages: By using a grinding cylinder placed within a accommodating cavity to hold the organic fertilizer raw material to be ground, and after the organic fertilizer raw material is poured into the grinding cylinder, the drive assembly is activated to drive the movable plate to reciprocate vertically. During the descent of the movable plate, the grinding head first falls vertically into the grinding cylinder until it contacts the cylinder. At this point, the grinding head presses against the organic fertilizer raw material, causing it to break. Because the distance between the grinding head and the grinding cylinder when the grinding head is completely withdrawn is less than the travel distance of the movable plate as it descends vertically under the drive assembly, as the movable plate continues to descend, the spherical heads at both ends of the connecting rod rotate in their respective connecting seats, causing the grinding head to move vertically towards the movable plate within the limiting frame while simultaneously grinding... The grinding head rotates inside the cylinder, crushing the organic fertilizer raw material. As the movable plate rises, the grinding head moves vertically away from the movable plate within the limiting frame under the action of gravity, while simultaneously rotating in the opposite direction inside the grinding cylinder to further crush the organic fertilizer raw material. After the grinding head rotates and resets, it exits the grinding cylinder as the movable plate rises. The drive assembly drives the movable plate to move back and forth, allowing the grinding head to continuously crush the organic fertilizer raw material inside the grinding cylinder until it is broken and falls into the receiving cavity through the through hole. In other words, only one grinding head is needed to process the organic fertilizer raw material for pressing and crushing. This solves the technical problems of existing grinding devices having complex structures and being inconvenient for later inspection and maintenance, resulting in a simplified device structure, easy disassembly and assembly, and convenient maintenance.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes an organic fertilizer raw material grinding device for grinding organic fertilizer raw materials to crush them, thereby improving the efficiency of subsequent organic fertilizer raw material fermentation.

[0025] Please refer to Figure 1 , Figure 3 and Figure 4 The organic fertilizer raw material grinding device includes a housing 1, which has a receiving cavity 11 and a grinding cylinder 2 is disposed within the receiving cavity 11. The grinding cylinder 2 has multiple through holes 21 spaced apart, each communicating with the receiving cavity 11. The housing 1 also has a liftable movable plate 3 and a drive assembly 4 connected to the movable plate 3. The movable plate 3 is located above the grinding cylinder 2. A limiting frame 5 is provided on the side of the movable plate 3 closest to the grinding cylinder 2. A grinding head 6 is disposed within the limiting frame 5, and the grinding head 6 can move vertically or rotate around the vertical direction within the limiting frame 5. A connecting rod 7 is provided between the movable plate 3 and the grinding head 6, and each end of the connecting rod 7 has a spherical head 71. The movable plate 3 and the grinding head 6 are respectively provided with connecting seats 8 that correspond one-to-one with the spherical head 71 on their respective sides. When the driving component 4 drives the movable plate 3 to move closer to or away from the grinding cylinder 2, the grinding head 6 extends into or retracts from the grinding cylinder 2, so as to press the organic fertilizer raw material placed in the grinding cylinder 2 through the grinding head 6. When the grinding head 6 completely retracts from the grinding cylinder 2, the distance between the grinding head 6 and the grinding cylinder 2 is less than the travel distance of the movable plate 3 when it moves vertically downward under the drive of the driving component 4, so that after the grinding head 6 enters the grinding cylinder 2, it can rotate in the grinding cylinder 2 as the movable plate 3 continues to descend, thereby crushing the organic fertilizer raw material in the grinding cylinder 2.

[0026] Specifically, the operation steps for crushing organic fertilizer raw materials using the organic fertilizer raw material grinding device provided in this embodiment are as follows: First, the organic fertilizer raw material is poured into the grinding cylinder 2. Then, the drive assembly 4 is activated to drive the movable plate 3 to reciprocate vertically. During the descent of the movable plate 3, the grinding head 6 is first driven to fall vertically into the grinding cylinder 2 until the grinding head 6 abuts against the grinding cylinder 2. At this time, the grinding head 6 presses against the organic fertilizer raw material to crush it. Since the distance between the grinding head 6 and the grinding cylinder 2 when the grinding head 6 is completely withdrawn from the grinding cylinder 2 is less than the travel distance of the movable plate 3 when it descends vertically under the drive assembly 4, after the grinding head 6 abuts against the grinding cylinder 2, as the movable plate 3 continues to descend, the spherical heads 71 ​​at both ends of the connecting rod 7 rotate in the corresponding connecting seats 8. The grinding head 6 moves vertically towards the movable plate 3 within the limiting frame 5 while rotating within the grinding cylinder 2. This rotation of the grinding head 6 crushes the organic fertilizer raw material. As the movable plate 3 rises, the grinding head 6 moves vertically away from the movable plate 3 within the limiting frame 5 under gravity, keeping it within the grinding cylinder 2. Simultaneously, the grinding head 6 rotates in the opposite direction within the grinding cylinder 2 to further crush the organic fertilizer raw material. After rotating and resetting, the grinding head 6 exits the grinding cylinder 2 as the movable plate 3 rises. The driving assembly 4 drives the movable plate 3 to reciprocate, allowing the grinding head 6 to continuously press and crush the organic fertilizer raw material within the grinding cylinder 2 until it is broken and falls through the through hole 21 into the receiving cavity 11. The organic fertilizer raw material grinding device provided in this embodiment only requires one grinding head 6 to perform stamping and crushing processing on the organic fertilizer raw material, which simplifies the structure of the organic fertilizer raw material grinding device and makes it easy to disassemble and install and facilitates later maintenance.

[0027] like Figure 2 As shown, the bottom of the housing 1 is provided with a discharge pipe 12 communicating with the accommodating cavity 11, and a discharge valve 13 is provided on the discharge pipe 12. The discharge pipe 12 is used to guide the crushed organic fertilizer raw material in the accommodating cavity 11 to be discharged from the accommodating cavity 11, and the discharge valve 13 is used to control the opening and closing of the discharge pipe 12, so as to control the discharge and collection of the organic fertilizer raw material in the accommodating trough, thereby facilitating the sending of the crushed raw material to the next station for processing.

[0028] In this embodiment, a guide surface 14 is provided at the bottom of the receiving cavity 11. The guide surface 14 is arranged around the discharge pipe 12, and the height of the guide surface 14 increases in the direction away from the discharge pipe 12. By providing the guide surface 14 at the bottom of the receiving cavity 11, the raw material in the receiving cavity 11 is guided to move towards the discharge pipe 12, ensuring that the raw material in the receiving cavity 11 can be quickly discharged from the discharge pipe 12, and avoiding the raw material from being retained in the receiving cavity 11.

[0029] like Figure 3 and Figure 4 As shown, the housing 1 is also provided with a mounting bracket 15. The mounting bracket 15 has two vertical guide grooves 16 spaced apart, and the two ends of the movable plate 3 extend into the guide grooves 16 respectively. The mounting bracket 15 is provided on the housing 1, and the two guide grooves 16 on the mounting bracket 15 are provided to cooperate with the two ends of the movable plate 3 respectively, so as to restrict the direction of movement of the movable plate 3 on the housing 1, prevent the movable plate 3 from deviating from the preset direction or deflecting, and ensure that the grinding head 6 is aligned with the opening of the grinding cylinder 2, so that the grinding head 6 can smoothly enter and exit the grinding cylinder 2 during the reciprocating movement of the movable plate 3 in the vertical direction.

[0030] In detail, the drive assembly 4 includes a motor 41 mounted on the mounting frame 15, a rocker arm 42 mounted on the output end of the motor 41, and a transmission rod 43 rotatably connected to the rocker arm 42. The end of the transmission rod 43 away from the rocker arm 42 is rotatably connected to the movable plate 3. When the rocker arm 42 rotates under the drive of the motor 41, it drives the transmission rod 43 to move and transmits the power output by the motor 41 to the movable plate 3. This causes the movable plate 3 to rise vertically under the pull of the transmission rod 43 or descend vertically under the push of the transmission rod 43. The continuous rotation of the rocker arm 42 driven by the motor 41 drives the movable rod to move back and forth in the vertical direction, thereby driving the grinding head 6 to repeatedly enter and exit the grinding cylinder 2 and rotate inside the grinding cylinder 2, ensuring the stable operation of the organic fertilizer raw material grinding device.

[0031] like Figure 2 and Figure 5As shown, the side of the grinding head 6 away from the grinding cylinder 2 has a limiting disk 61. The limiting frame 5 includes a plurality of limiting rods 51 spaced circumferentially along the grinding head 6, and each limiting rod 51 has a bent portion 52 at its end away from the movable plate 3. The limiting rods 51 are respectively attached to the outer peripheral wall of the limiting disk 61, and the bent portion 52 abuts against the side of the limiting disk 61 away from the movable plate 3. The limiting frame 5 includes a plurality of limiting rods 51 that are respectively attached to the limiting disk 61. By limiting the movement direction of the limiting disk 61 by the limiting rods 51, unexpected deviations can be prevented when the grinding head 6 moves. At the same time, the bent portions 52 that abut against the limiting disk 61 are respectively provided at the ends of the limiting rods 51, so that the limiting disk 61 is kept within the limiting frame 5, preventing the grinding head 6 from falling out of the limiting frame 5, which helps to improve the structural stability of the organic fertilizer raw material grinding device.

[0032] Specifically, a rotatable limiting ring 62 is fitted onto the limiting disc 61, and the diameter of the limiting ring 62 is larger than the diameter of the opening of the grinding cylinder 2. When the grinding head 6 is fully inserted into the grinding cylinder 2 under the drive of the movable plate 3, the limiting ring 62 abuts against the top surface of the grinding cylinder 2. At this time, the grinding head 6 cannot continue to descend vertically. As the movable plate 3 continues to descend, the grinding head 6 can rotate inside the grinding cylinder 2, and the relative position of the limiting ring 62 and the grinding cylinder 2 remains fixed when the grinding head 6 rotates, so as to reduce the friction between the grinding head 6 and the grinding cylinder 2 and reduce the wear of the organic fertilizer raw material grinding device.

[0033] Please refer to Figure 5 The grinding head 6 has multiple protruding ridges 63 on the side near the grinding cylinder 2, and these ridges 63 are spaced apart circumferentially on the grinding head 6. By providing multiple protruding ridges 63 on the surface of the grinding head 6, the contact area between the grinding head 6 and the raw material in the grinding cylinder 2 can be increased, thereby enhancing the crushing effect of the grinding head 6 on the raw material when it rotates, so that the material in the grinding cylinder 2 can be crushed quickly.

[0034] like Figure 1 and Figure 4 As shown, in this embodiment, three connecting rods 7 are provided between the movable plate 3 and the grinding head 6, and the connecting rods 7 are equally spaced along the circumference of the grinding head 6. The three connecting rods 7 are provided between the movable plate 3 and the grinding head 6, and three connecting seats 8 are respectively provided on the movable plate 3 and the grinding head 6 to correspond one-to-one with the spherical heads 71 ​​at the ends of the connecting rods 7, thereby improving the reliability of the connection between the grinding head 6 and the movable plate 3 and ensuring that the grinding head 6 can rotate smoothly.

[0035] like Figure 5 As shown, the connecting seat 8 includes a seat body 81 and a cover body 82 fixedly connected. The seat body 81 and the cover body 82 form a spherical groove for accommodating the spherical head 71, and the cover body 82 is provided with a through hole 83 communicating with the spherical groove. The connecting seat 8 includes a seat body 81 and a cover body 82 fixedly connected to the seat body 81. The seat body 81 and the cover body 82 form the spherical groove, and the cover body 82 presses the spherical head 71 into the spherical groove, so that the connection between the grinding head 6 and the movable plate 3 remains stable. When the connecting rod 7 rotates, the spherical head 71 rolls in the spherical groove, thereby ensuring that the grinding head 6 can rotate smoothly under the push of the connecting rod 7.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
