Description

Technical Field

[0001] This invention relates to the field of agricultural engineering technology, and in particular to an agricultural machinery fertilization device. Background Technology

[0002] Fertilization is a crucial operation in agricultural production, aiming to replenish crops with the various nutrients they need for growth, ensuring robust growth and achieving good yield and quality. In field operations, fertilizer carts are often used to assist in fertilization. These carts are typically equipped with a hopper to hold fertilizer, with a discharge port at the bottom. The operator pushes the cart forward, causing the gears to rotate a centrifugal disc. As the cart moves, fertilizer falls onto the disc, which, through its rotation, evenly distributes the fertilizer onto the soil surface. This replenishes the soil's nutrient content, meeting the needs of crops at different growth stages and promoting healthy growth and development. Different types of fertilizers vary in particle size and specifications. Fertilizers have varying properties; for example, large-particle, high-density fertilizers require stronger centrifugal force for effective spreading, necessitating a higher centrifugal disc rotation speed. However, in current technology, operators often adjust the centrifugal disc rotation speed by accelerating the movement of a small cart. Prolonged, continuous acceleration of the cart requires significant physical exertion, leading to fatigue, especially in large-scale farmland fertilization where maintaining a high cart speed demands even more physical strength. As physical strength declines, maintaining a stable cart speed becomes difficult, affecting the stable adjustment of the centrifugal disc rotation speed, and may even prevent the operator from continuing work, reducing fertilization efficiency and prolonging the total fertilization time.

Detailed Implementation

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0039] Reference Figures 1-20 This is the first embodiment of the present invention. This embodiment provides an agricultural machinery fertilization device, which includes a main body component and a fertilization component. The two components work together to adjust the speed of the centrifugal disc when pushing the trolley, eliminating the need for long-term acceleration of pushing the trolley, reducing the physical burden on the operator, stabilizing the speed, improving fertilization efficiency, and ensuring the smooth progress of fertilization work.

[0040] The main component 100 includes a storage bin 101, a frame 102 fixed to the bottom of the storage bin 101, a roller 103 on one side of the frame 102, and a centrifugal disc 104 below the storage bin 101.

[0041] When fertilization is needed, first place the fertilizer in the storage box 101. Then, the user drives the roller 103 to rotate by pushing the handle on the frame 102. The rotation of the roller 103 drives the centrifugal disc 104 to rotate. At this time, open the discharge port at the bottom of the storage box 101, and the fertilizer in the storage box 101 will fall onto the centrifugal disc 104. The rotation of the centrifugal disc 104 will sprinkle the fertilizer out, thus completing the fertilization.

[0042] The fertilizer application component 200 is mounted on the frame 102 and includes a fertilizer application element 201. The fertilizer application element 201 includes a crushing roller 201a, which is rotatably connected to the inner wall of the frame 102 via a rotating shaft. An adjustment plate 201b is provided below the centrifugal disc 104. A chain 201c is sleeved on the outside of the adjustment plate 201b. A drive plate 201d is provided inside the chain 201c. A pull rope 201e is provided on one side of the adjustment plate 201b.

[0043] There are three adjusting discs 201b, with their sizes increasing progressively. By moving the chain 201c to different adjusting discs 201b, the centrifugal disc 104 can generate different rotational speeds and centrifugal forces, thus adjusting the fertilization range. The user can move the chain 201c to different sized adjusting discs 201b by pulling the pull rope 201e. The drive disc 201d is fitted onto the outside of the long shaft of the roller 103. The long shaft is rotatably connected to the frame 102 via a rotating shaft. When the frame 102 is pushed, the roller 103 rotates, which in turn rotates the long shaft, which in turn rotates the drive disc 201d. The rotation of the drive disc 201d can drive the chain 201c to rotate, and the rotation of the chain 201c can drive the adjustment disc 201b to rotate. At this time, the rotation of the adjustment disc 201b can drive the centrifugal disc 104 to rotate. When the chain 201c is on the smallest adjustment disc 201b, the crushing roller 201a will not rotate. When the chain 201c moves to the medium-sized and largest adjustment discs 201b, the crushing roller 201a can rotate to break up the fertilizer and spread it on the land. The crushing roller 201a consists of a roller shaft and a roller body. The roller body is cylindrical and has a raised structure on its surface. When rotating, it uses these structures to impact and squeeze the fertilizer to break up the clumps of fertilizer, which is suitable for fertilizer pretreatment in small-scale precision fertilization scenarios.

[0044] When the chain is at the larger adjustment disc 201b, the centrifugal disc 104 rotates slowly, and the fertilizer spreading range is small. At this time, the linkage clutch 203 is activated, and the drive column 203c drives the rotating column 203a through the drive sleeve 203b, causing the crushing roller 201a to work. Because the spreading range is small, although the crushed debris is not thrown far, it can be evenly distributed within a small area by the slow rotation of the centrifugal disc, allowing for precise fertilization. On the smallest adjustment disc 201b, the centrifugal disc rotates quickly, and the spreading range is large. If the crushing roller works, the debris will accumulate in the middle of the fertilization area because it cannot be thrown far, which will disrupt the uniformity of fertilization over a large area. Moreover, the uncrushed fertilizer can be dispersed and spread under the centrifugal force of the high speed, which meets the needs of a large area. Therefore, the crushing roller 201a does not work at this time. Example 2

[0045] Reference Figures 2-20 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0046] Specifically, the fertilizer application component 200 also includes a movable part 202, which includes a first gear 202a, which is fixed to the bottom of the centrifugal disc 104. A second gear 202b is provided at the bottom of the first gear 202a. The first gear 202a and the second gear 202b mesh with each other, and the second gear 202b is fixed to one side of the adjusting disc 201b.

[0047] The adjusting disc 201b is fixed to one side of the second gear 202b, which is located at the bottom of the frame 102. The second gear 202b and the bottom of the frame 102 are rotatably connected by a rotating shaft. When the adjusting disc 201b rotates, it can drive the second gear 202b to rotate. At this time, the rotation of the second gear 202b can drive the first gear 202a to rotate, and then the rotation of the first gear 202a can drive the centrifugal disc 104 to rotate. The first gear 202a is rotatably connected to the bottom of the frame 102 by a rotating shaft.

[0048] Specifically, a drive wheel 202c is provided inside the chain 201c, and a support frame 202d is sleeved on the outside of the drive wheel 202c. The drive wheel 202c and the support frame 202d are rotatably connected by a rotating shaft. A support wheel 202e is provided at one end of the support frame 202d. The support frame 202d and the support wheel 202e are rotatably connected by a rotating shaft. An adjusting plate 202f is provided on one side of the support frame 202d, and a return torsion spring 202g is fixed on one side of the adjusting plate 202f. One end of the return torsion spring 202g is fixed to one side of the support frame 202d.

[0049] Moving the drive wheel 202c moves the chain 201c, allowing it to move onto the adjusting discs 201b of different sizes. The support frame 202d is fitted over the chain 201c and is movably connected to it. The support wheel 202e supports the chain 201c. Moving the adjusting plate 202f moves the support frame 202d, which in turn moves the drive wheel 202c. The return torsion spring 202g torsionalize the support frame 202d, keeping it taut. This ensures that the support wheel 202e supports the chain 201c, preventing it from loosening during adjustment.

[0050] A flip plate is hinged to the top of the adjusting plate 202f. The top of the flip plate is hinged to the positioning frame 202h. Initially, the flip plate is at the initial angle. The adjusting plate 202f maintains its initial position under the action of the first torsion spring 202j. The support frame 202d engages with the initial adjusting disc 201b via the return torsion spring 202g supporting the chain 201c. When the pull rope 201e is pulled, the pull rope drives the winding wheel 202i to rotate and twist the first torsion spring 202j, thus adjusting the position. When plate 202f is subjected to force, it swings around the double hinge point of the flip plate as an axis. The flip plate restricts its trajectory to prevent deviation, thereby driving the support frame 202d to move. This causes the drive wheel 202c and support wheel 202e to push the chain 201c to switch to the target adjustment plate 201b. The reset torsion spring 202g keeps the chain taut. After the pull rope 201e is released, the first torsion spring 202j resets and drives the winding wheel 202i and adjustment plate 202f back to their original positions. The flip plate guides the adjustment plate to stabilize in the corresponding position, and the chain 201c stably engages with the target adjustment plate 201b to complete the adjustment.

[0051] Specifically, a positioning frame 202h is hinged to the top of the adjusting plate 202f. The positioning frame 202h is fixed to the bottom of the frame 102. A roller 202i is provided on one side of the adjusting plate 202f. A first torsion spring 202j is fixed on one side of the roller 202i. One end of the first torsion spring 202j is fixed to one side of the positioning frame 202h. The pull rope 201e is located inside the roller 202i.

[0052] When it is necessary to move the adjusting plate 202f, the pull rope 201e can be pulled to drive the roller 202i to rotate. At this time, the rotation of the roller 202i can apply a torsional force to the first torsion spring 202j. Then, the rotation of the roller 202i can drive the adjusting plate 202f to move. The positioning frame 202h can support the adjusting plate 202f to prevent the adjusting plate 202f from shifting. The roller 202i is rotatably connected to one side of the positioning frame 202h through a rotating shaft. The roller 202i is fixed to one side of the flip plate. The roller (202i) is rotatably connected to the positioning frame (202h) and fixed to the flip plate. When the pull rope (201e) is pulled or reset, it cooperates with the flip plate to transmit force to drive the adjusting plate (202f) to move, so as to realize the switching of the chain (201c) on the adjusting plate (201b).

[0053] Specifically, the pull rope 201e is inserted into one side of the frame 102, and the pull rope 201e and the frame 102 are movably connected. A connecting plate 202k is movably connected to the outside of the pull rope 201e, and a fixed pulley 202l is provided on one side of the pull rope 201e. The fixed pulley 202l and the connecting plate 202k are rotatably connected through a rotating shaft.

[0054] The connecting plate 202k is fixed to the bottom of the frame 102. The connecting plate 202k can support the pull rope 201e and prevent the pull rope 201e from deviating. When the pull rope 201e moves, it can move on the fixed pulley 202l. At this time, the fixed pulley 202l can guide the pull rope 201e so that it can move within the frame 102. Smooth support pads are provided at the junction of the frame 102 and the pull rope 201e to reduce the friction of the pull rope 201e, making the movement of the pull rope 201e smoother and preventing excessive wear on the pull rope 201e. Example 3

[0055] Reference Figures 1-20 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0056] Specifically, the fertilization assembly 200 also includes a clutch 203, which includes a rotating column 203a. The rotating column 203a is fixed to one side of the crushing roller 201a. A drive sleeve 203b is movably connected to the outside of the rotating column 203a. One end of the drive sleeve 203b is inserted into the drive column 203c. A protective box 203d is sleeved on the outside of the drive column 203c. The drive column 203c and the protective box 203d are rotatably connected by a rotating shaft. A first spring 203e is fixed to one side of the drive sleeve 203b. One end of the first spring 203e is fixed to the inner wall of the protective box 203d.

[0057] A first pulley is fixed to one side of the adjusting disc 201b. A belt is fitted around the outside of the first pulley, and a second pulley is installed inside the belt. The second pulley is fixed to one end of the drive column 203c. The rotating column 203a is rotatably connected to one side of the frame 102 via a rotating shaft. When the chain 201c is moved onto the larger adjusting disc 201b, it can drive the drive sleeve 203b to move. When the drive sleeve 203b moves, it can apply a pulling force to the first spring 203e. Then, through the drive column 203c, the drive sleeve 203b can be rotated. The rotation of the drive sleeve 203b can... The rotating column 203a is driven to rotate, which in turn drives the crushing roller 201a to rotate. When the adjusting disc 201b rotates, it drives the first pulley to rotate. The first pulley drives the belt to rotate, which in turn drives the second pulley to rotate. The second pulley then drives the drive column 203c to rotate. When the first spring 203e rebounds and drives the drive sleeve 203b back to its original position, the drive sleeve 203b can then separate from the rotating column 203a. After that, the adjusting disc 201b will not drive the crushing roller 201a to rotate when it rotates.

[0058] Specifically, a retaining strip 203n is fixed on one side of the rotating column 203a, a driving strip 203f is fixed on one side of the driving column 203c, and a driving plate 203g is sleeved on the outside of the driving sleeve 203b. The driving sleeve 203b and the driving plate 203g are rotatably connected by a bearing.

[0059] A slot corresponding to the locking strip 203n is provided on the drive sleeve 203b, and a groove corresponding to the drive strip 203f is provided at the other end of the drive sleeve 203b. When the drive sleeve 203b moves, it can drive the slot to engage with the locking strip 203n. Then, the drive sleeve 203b can be moved by the movement of the drive plate 203g. At this time, the drive sleeve 203b can drive the groove to slide on the drive strip 203f. Then, the drive column 203c rotates, causing the groove to press against the drive strip 203f, causing the drive sleeve 203b to rotate. The rotation of the drive sleeve 203b can drive the slot to press against the locking strip 203n, thereby causing the rotating column 203a to rotate. When the force of the first spring 203e rebounds, it causes the drive sleeve 203b to return to its original position. At this time, the slot can be separated from the drive sleeve. Then, the rotation of the drive sleeve 203b will not drive the rotating column 203a to rotate, thereby preventing the crushing roller 201a from rotating.

[0060] Specifically, a pressing block 203h is fixed to the top of the drive plate 203g, a pressing wheel 203i is provided on one side of the pressing block 203h, a support block 203j is movably connected to the outside of the pressing wheel 203i, a rotating plate 203k is fixed to one end of the pressing wheel 203i, a hinge rod 203l is hinged to the bottom of the rotating plate 203k, a second torsion spring 203m is fixed to one side of the rotating plate 203k, and one end of the second torsion spring 203m is fixed to one side of the support block 203j.

[0061] The frame 102 has a pre-set wiring channel for the pull rope 201e. The wiring groove on the frame 102 ensures the directional movement of the pull rope 201e. A support block 203j is fixed to the top of the protective box 203d, which is fixed to one side of the frame 102. The protective box 203d supports the drive column 203c. The support block 203j supports the compression wheel 203i, preventing it from shifting. A plug is inserted into the top of the hinge rod 203l, movably connected to it and fixed to one side of the frame 102. The hinge rod 203l is located on the side of the pull rope 201e. A triangular bracket is installed at the bottom of the hinge rod 203l, with one top end fixed to the bottom of the bracket. The bracket is fixed to the side of the pull rope 201e. The hinge rod 203l and one side of the frame 102... The movable connection allows the chain 201c to be adjusted to the larger adjusting disc 201b by pulling the pull rope 201e. The movement of the pull rope 201e can drive the tripod to move. The movement of the tripod can move the force point of the hinge rod 203l to the middle. Then, the movement of the tripod will drive the hinge rod 203l to move. A support groove is provided on one side of the frame 102. One end of the hinge rod 203l and the tripod are slidably connected in the support groove, and one end of the hinge rod 203l is fixed to one side of the pull rope 201e. When the hinge rod 203l moves, it can move on the insert rod to prevent the hinge rod 203l from deviating. The movement of the hinge rod 203l can drive the rotating plate 203k to rotate. The range of movement of the hinge rod 203l and the rotating plate 203k is within the belt and will not affect the rotation of the belt. There is enough gap in the middle of the belt for the two to move.

[0062] The rotation of the rotating plate 203k applies a torsional force to the second torsion spring 203m. This rotation of the rotating plate 203k then drives the pressing wheel 203i to rotate. A convex surface is provided on one side of the pressing wheel 203i. The rotation of the pressing wheel 203i causes the convex surface to contact the pressing block 203h, thus pressing the pressing block 203h. The movement of the pressing block 203h drives the drive plate 203g to move, thereby causing the drive sleeve 203b to engage the slot and the locking strip 203n. When the pull rope 201e returns to its original position, driving the chain 201c back to its original position, and the chain 201c moves to the initially smaller adjusting disc 201b, the force of the second torsion spring 203m's rotation drives the pressing wheel 203i to rotate, releasing the pressing block 203h. Then, the rebound force of the first spring 203e drives the drive sleeve 203b back to its original position, separating the slot and the locking strip 203n.

[0063] The extrusion roller 203i extrudes the extrusion block 203h by rotating, which in turn drives the drive plate 203g and drive sleeve 203b to move. This causes the drive sleeve 203b to engage with the locking strip 203n on the rotating column 203a, thereby transmitting the power of the drive column 203c to the rotating column 203a. Ultimately, this drives the crushing roller 201a to rotate. When the extrusion roller 203i resets, it releases the extrusion block 203h. Under the action of the first spring 203e, the drive sleeve 203b separates from the locking strip 203n, and the crushing roller 201a stops working.

[0064] Specifically, the fertilizer application component 200 also includes a drive component 204, which includes a drive ring 204a. The drive ring 204a is fixed to one end of the pull rope 201e. A slide rod 204b is inserted into one side of the drive ring 204a. A limit block 204c is provided inside the drive ring 204a. A moving strip 204d is fixed to one side of the limit block 204c. A pull plate 204e is fixed to one end of the moving strip 204d.

[0065] The slide bar 204b is fixed to one side of the frame 102. When the pull rope 201e needs to be moved, the drive ring 204a is moved. At this time, the drive ring 204a can move on the slide bar 204b, thereby moving the drive ring 204a to a designated position, which in turn moves the chain 201c to the adjusting disc 201b of different sizes. The slide bar 204b has three limiting grooves corresponding to the limiting block 204c. When the drive ring 204a is moved to the designated position... Afterwards, to prevent the drive ring 204a from moving on its own, the drive ring 204a can be limited by engaging the limit block 204c with the limit groove. When it is necessary to release the limit on the drive ring 204a, the limit block 204c is separated from the limit groove by moving the moving bar 204d, thereby releasing the limit on the drive ring 204a, and then the drive ring 204a can be moved. The pull plate 204e is designed to facilitate the user to move the moving bar 204d.

[0066] Specifically, a compression plate 204f is sleeved on the outside of the moving strip 204d, a second spring 204g is fixed on one side of the compression plate 204f, and a support sleeve 204h is sleeved on the outside of the second spring 204g.

[0067] When the moving strip 204d moves to separate the limiting block 204c from the limiting groove, the pressing disc 204f can be moved. The movement of the pressing disc 204f applies a compressive force to the second spring 204g, which releases the limiting force on the drive ring 204a and allows it to move. After the drive ring 204a is moved to the designated position, the moving strip 204d is released. The rebound force of the second spring 204g causes the limiting block 204c to engage with the limiting groove, thus limiting the drive ring 204a. The support sleeve 204h is fitted over the moving strip 204d. On the side, the support sleeve 204h and the moving strip 204d are movably connected, and the support sleeve 204h is fixed to one side of the drive ring 204a. The support sleeve 204h can support the moving strip 204d and prevent the moving strip 204d from shifting. A positioning strip is inserted into the bottom of the drive ring 204a and is fixed to one side of the frame 102. The positioning strip and the drive ring 204a are movably connected. When the drive ring 204a is moved, it can move on the positioning strip. The movement of the positioning strip can support the drive ring 204a and prevent the drive ring 204a from rotating when it moves.

[0068] The three states of the first spring 203e correspond to the engagement modes of the chain 201c in the small, medium, and large adjusting discs 201b. In the small adjusting disc mode, the first spring 203e is reset, the drive sleeve 203b is separated from the rotating column 203a, and the crushing roller 201a does not work. In the medium and large adjusting disc modes, the first spring 203e is stretched, the drive sleeve 203b is engaged with the rotating column 203a, and the crushing roller 201a is activated. The adjusting discs 201b are divided into small, medium, and large, corresponding to different spreading modes. The small disc is suitable for high-speed, large-area spreading, and the strong centrifugal force makes the uncrushed fertilizer spread evenly, avoiding the accumulation of debris in the inner circle. The medium and large discs are for low-speed, small-area spreading, and the crushing roller 201a breaks up the clumps of fertilizer. The slow speed ensures even distribution in a small area. The difference between the medium and large discs lies in the spreading range and the crushing precision gradient. The large disc corresponds to a smaller area and higher crushing precision, while the medium disc balances the range and uniformity, adapting to the needs of precise fertilization in different areas.

[0069] In use, fertilizer is first placed in the storage bin 101. Then, the user drives the roller 103 to rotate by pushing the handle on the frame 102. As the roller 103 rotates, the drive disc 201d, which is fitted onto the outside of the long shaft of the roller 103 and is rotatably connected to the frame 102 via bearings, causes the long shaft to rotate, which in turn drives the drive disc 201d to rotate. The drive disc 201d then drives the chain 201c to rotate. Next, the discharge port at the bottom of the storage bin 101 is opened, and the fertilizer in the storage bin 101 falls onto the centrifugal disc 104. The rotation of the chain 201c causes the adjusting discs 201b to rotate. There are three adjusting discs 201b, which increase in size progressively. By moving the chain 201c to different adjusting discs 201b, the centrifugal disc 104 can generate different rotation speeds and different centrifugal forces, thereby adjusting the fertilization range.

[0070] When it is necessary to adjust the adjusting disc 201b where the chain 201c is located, the user pulls the pull rope 201e, which is located inside the reel 202i. Pulling the pull rope 201e will cause the reel 202i to rotate. The rotation of the reel 202i will apply a torsional force to the first torsion spring 202j and drive the adjusting plate 202f to move. The adjusting plate 202f is supported by the positioning frame 202h to prevent displacement. The movement of the adjusting plate 202f will drive the support frame 202d to move. The movement of the support frame 202d will drive the drive wheel 202c to move, thereby moving the chain 201c to the desired position. On the adjusting discs 201b of different sizes, and the support wheel 202e on the outside of the support frame 202d, the chain 201c is supported. The return torsion spring 202g keeps the support frame 202d taut at all times, preventing the chain 201c from loosening during adjustment. The pull rope 201e is guided by the fixed pulley 202l when moving. The smooth support pad set at the junction of the frame 102 and the pull rope 201e reduces friction, making its movement smoother and avoiding excessive wear. At the same time, the connecting plate 202k supports the pull rope 201e to prevent it from deviating.

[0071] When chain 201c is on the smallest adjusting disc 201b, crushing roller 201a will not rotate. This corresponds to a situation where the fertilization range is small and the fertilization area is relatively precise. For example, for precise fertilization near the crop roots, fertilizer can be directly spread to ensure concentrated supply to the crop roots, avoiding excessive dispersion of nutrients and failure to efficiently meet the crop roots' absorption needs.

[0072] When chain 201c moves to the medium-sized and largest adjusting discs 201b, the crushing roller 201a rotates to crush the fertilizer. Adjusting disc 201b is fixed to one side of the second gear 202b, which is rotatably connected to the bottom of the frame 102 via a shaft. A first pulley is fixed to one side of adjusting disc 201b, and it is connected to a second pulley fixed to one end of the drive column 203c via a belt. When chain 201c moves to the larger adjusting disc 201b, the adjustment disc 201b rotates, causing the first pulley to rotate, thereby... The belt drives the second pulley to rotate, which in turn drives the drive column 203c to rotate. Simultaneously, it moves the drive sleeve 203b. The movement of the drive sleeve 203b applies a pulling force to the first spring 203e. The drive sleeve 203b has a slot corresponding to the locking bar 203n and a groove corresponding to the drive bar 203f. The movement of the drive sleeve 203b causes the slot to engage with the locking bar 203n. Meanwhile, the hinge rod 203l, connected to the pull rope 201e, moves when the pull rope 201e is pulled and the adjusting chain 201c is moved. The movement of the hinge rod 203l drives the rotating plate 20... Rotating plate 203k applies a torsional force to the second torsion spring 203m, causing the extrusion wheel 203i to rotate. The extrusion wheel 203i then extrudes the extrusion block 203h. The extrusion block 203h moves, causing the drive plate 203g to move. The drive plate 203g moves, causing the drive sleeve 203b to move, which in turn causes the drive sleeve 203b to slide along the slide groove on the drive bar 203f. The drive column 203c rotates, causing the slide groove to press against the drive bar 203f, thus rotating the drive sleeve 203b. The rotation of the drive sleeve 203b then causes the slot to press against the slot bar 203n, thereby causing rotation. The rotation of column 203a drives the crushing roller 201a to rotate, breaking up the fertilizer and spreading it on the land. This way, when fertilizing at a larger setting, the fertilizer can be evenly distributed over a larger area, allowing more soil areas to receive the appropriate amount of fertilizer, reducing waste and improving fertilizer utilization efficiency. The inner wall of the protective box 203d is provided with a support groove, and the bottom of the drive plate 203g is fixed with a support slider. The support slider slides in the support groove. When the drive plate 203g moves, it can drive the support slider to slide in the support groove, preventing the drive plate 203g from rotating during movement.

[0073] When the pull rope 201e returns to its original position, it drives the chain 201c to return to its original position, causing the chain 201c to move onto the initially smaller adjusting disc 201b. The force of the second torsion spring 203m rotating causes the extrusion wheel 203i to rotate, releasing the extrusion block 203h from compression. Then, the force of the first spring 203e rebounding causes the drive sleeve 203b to return to its original position, separating the slot and the clip 203n. The rotation of the drive sleeve 203b will not drive the rotating column 203a to rotate, thus stopping the crushing roller 201a from rotating. Additionally, when the adjusting disc 201b rotates, it drives the first gear 202a, which meshes with it, to rotate via the second gear 202b fixed to it. The first gear 202a is fixed to the bottom of the centrifugal disc 104, thereby driving the centrifugal disc 104 to rotate, allowing fertilizer to be sprayed out through the rotation of the centrifugal disc 104, completing the fertilization process. When operating the drive ring 204a at one end of the pull rope 201e, to move the pull rope 201e, the drive ring 204a can be moved. The drive ring 204a moves to a designated position on the slide rod 204b. The slide rod 204b has three limiting grooves corresponding to the limiting blocks 204c. After moving to the designated position, the limiting blocks 204c engage with the limiting grooves to limit the drive ring 204a. To release the limitation, the moving bar 204d is moved to separate the limiting blocks 204c from the limiting grooves. The movement of the moving bar 204d drives the pressing disc 204f to move, applying a pressing force to the second spring 204g. After releasing the limitation on the drive ring 204a, it can be moved. After the drive ring 204a moves to the designated position, the moving bar 204d is released. The rebound force of the second spring 204g drives the limiting block 204c to engage with the limiting groove, thereby limiting the drive ring 204a again. The support sleeve 204h supports the moving bar 204d to prevent it from shifting. By repeating this operation, the fertilization range and whether the fertilizer is broken up can be flexibly adjusted according to the actual fertilization needs to complete the fertilization operation. A sliding rod is movably connected inside the drive ring 204a. The sliding rod is fixed to one side of the frame 102. When the drive ring 204a moves, it can move on the sliding rod, thereby supporting the drive ring 204a and preventing it from shifting during movement.
