[0032] By setting up a structure in which the fertilizer tank assembly 1, chassis assembly 2, crane system 3, spreading system 5, and power control system 4 work together, the spreader can not only move easily in various farming environments and improve work efficiency, but also automatically and effectively load heavy fertilizers to achieve the effect of self-loading of the fertilizer spreader. This reduces labor intensity and improves loading efficiency.

[0033] Specifically, refer to Figure 1 and Figure 2 In this embodiment, the fertilizer tank assembly 1 includes a fertilizer tank body 11, a fertilizer discharge and conveying device, and a gate device. The fertilizer tank body 11 is mounted on top of the chassis assembly 2, and its side panels are made of corrosion-resistant material. The fertilizer discharge and conveying device is installed at the bottom of the fertilizer tank body 11 to facilitate the conveying of organic fertilizer, other granular fertilizers, conditioners, etc. The gate device is installed inside the rear side of the fertilizer tank body 11 to control the size of the fertilizer discharge port at the rear end of the fertilizer tank body 11, thereby effectively regulating the amount of fertilizer discharged from the fertilizer tank body 11.

[0034] The structure of the fertilizer conveying device and the gate device is described in detail below:

[0035] More specifically, refer to Figure 1 and Figure 2 In this embodiment, the fertilizer discharge and conveying device includes an active conveying shaft 12, a driven conveying shaft 13, a fertilizer discharge conveying belt 14, a fertilizer discharge chain 141, and a fertilizer discharge sprocket 15. The active conveying shaft 12 is rotatably mounted on the rear side of the fertilizer box 11, and one end of the active conveying shaft 12 is connected to the spreading system 5, so that the spreading system 5 drives the active conveying shaft 12 to rotate.

[0036] Meanwhile, the driven conveying shaft 13 is rotatably mounted on the front side of the fertilizer box 11, and the driven conveying shaft 13 and the active conveying shaft 12 are arranged parallel to each other; the fertilizer discharge conveyor belt 14 is wound between the active conveying shaft 12 and the driven conveying shaft 13, and the fertilizer discharge conveyor belt 14 includes a conveyor frame and a conveyor plate. The conveyor frame is wound between the active conveying shaft 12 and the driven conveying shaft 13, and the conveyor plate is mounted on the conveyor frame and is made of corrosion-resistant material.

[0037] In addition, there are two fertilizer discharge chains 141, which are symmetrically installed on both sides of the fertilizer discharge conveyor belt 14; there are four fertilizer discharge sprockets 15, which are arranged in pairs. The two sets of fertilizer discharge sprockets 15 are symmetrically installed on both ends of the active conveyor shaft 12 and both ends of the driven conveyor shaft 13, and the two sets of fertilizer discharge sprockets 15 are respectively meshed with the two fertilizer discharge chains 141.

[0038] When the spreading system 5 drives the active conveyor shaft 12 to rotate, the two fertilizer discharge sprockets 15 on the active conveyor shaft 12 also rotate. With the cooperation of the fertilizer discharge conveyor belt 14, the other two fertilizer discharge sprockets 15, and the driven conveyor shaft 13, the fertilizer discharge conveyor belt 14, the other two fertilizer discharge sprockets 15, and the driven conveyor shaft 13 rotate simultaneously. This allows the fertilizer discharge conveyor belt 14 to transport the organic fertilizer in the fertilizer box 11, and then uniformly transport the organic fertilizer to the spreading system 5, so that the spreading system 5 can perform the fertilizer spreading operation.

[0039] More specifically, refer to Figure 1 and Figure 2 In this embodiment, the gate device includes a support rod 16, a gate frame 161, a gate 162, and a gate hydraulic cylinder 163.

Both cylinders are electrically connected to the power control system 4, enabling the power control system 4 to provide power to the gate hydraulic cylinders 163 for effective control of their activation.

[0040] When both gate hydraulic cylinders 163 are activated simultaneously, the output ends of the two gate hydraulic cylinders 163 simultaneously drive the gate frame 161 to move up and down inside the fertilizer box 11, so that the gate frame 161 drives the gate 162 to move up and down, thereby controlling the size of the fertilizer discharge port at the rear end of the fertilizer box 11, and thus effectively regulating the amount of fertilizer discharged from the fertilizer box 11.

[0041] Better, refer to Figure 1 and Figure 2 In this embodiment, a rain shelter 17 is slidably installed on the top of the fertilizer container 11. The rain shelter 17 can be folded or unfolded.

The sliding tracks 18 cooperate with the sliding wheels, allowing the wheels to slide against the tracks 18. This structure, with the rain shelter 17, sliding wheels, and sliding tracks 18 working together, ensures that the rain shelter 17 covers the top of the fertilizer container 11, effectively protecting it from rain and preventing fertilizer from being blown away.

[0042] At the same time, refer to Figure 1 and Figure 3 In this embodiment, the chassis assembly 2 includes a chassis support frame 21 and a tracked chassis 22. The chassis support frame 21 is installed at the bottom of the fertilizer box 11.

The chassis frame 221 is mounted on one side of the chassis support frame 21. The drive wheel 222 is rotatably mounted on the front side of the chassis frame 221. The travel motor 223 is mounted on the chassis frame 221, and its output end is connected to the drive wheel 222. The travel motor 223 is also electrically connected to the power control system 4, so that the power control system 4 provides hydraulic power to the travel motor 223.

[0044] The idler wheel 224 is installed on the rear side of the chassis frame 221; the track 225 is wound between the drive wheel 222 and the idler wheel 224; multiple road wheels 226 are provided, and the multiple road wheels 226 are rotatably installed on the bottom side of the chassis frame 221, and the road wheels 226 abut against each other with the inner side of the track 225; the track support roller 227 is rotatably installed on the top side of the chassis frame 221, and the track support roller 227 abuts against the inner side of the track 225.

[0045] By setting up a structure in which the chassis frame 221, drive wheel 222, travel motor 223, idler wheel 224, track 225, road wheel 226, and track support wheel 227 work together, the power control system 4 can provide hydraulic power to control the left and right travel motors 223 to move forward or backward, as well as adjust their speed or turn, thus enabling the entire fertilizer spreader to move in various farming environments.

[0046] Additionally, refer to Figure 1 In this embodiment, the crane system 3 includes a support column 31, a support frame 32, a rotation adjustment device, a support arm 33, a height adjustment device, a lifting device, and a hook 34. The support column 31 is installed at the front of the fertilizer box 11; the support frame 32 is rotatably mounted on the top of the support column 31; the rotation adjustment device is located between the support column 31 and the support frame 32 to drive the support frame 32 to rotate on the support column 31; one end of the support arm 33 is hinged to the top of the support frame 32; the height adjustment device is located between the support frame 32 and the support arm 33 to drive the support arm 33 to adjust its height; the lifting device is installed on the support arm 33; and the hook 34 is connected to the output end of the lifting device and is located at the end of the support arm 33 furthest from the support frame 32. Under the action of the lifting device, the hook 34 is driven to perform traction and lifting, thereby enabling the lifting of heavy objects using the hook 34.

[0047] Meanwhile, the rotation adjustment device, the height adjustment device, and the lifting device are electrically connected to the power control system 4, enabling the power control system 4 to provide power and effectively control the rotation adjustment device, the height adjustment device, and the lifting device.

[0048] The structure of the rotation adjustment device, height adjustment device, and lifting device is described in detail below:

[0049] Specifically, refer to Figure 1In this embodiment, the rotation adjustment device includes a stabilizing plate frame 311, a first swing plate assembly, and a rotation adjustment hydraulic cylinder 35. One end of the stabilizing plate frame 311 is fixedly mounted on one side of the top of the support column 31; the first swing plate assembly is mounted on one side of the support frame 32; one end of the rotation adjustment hydraulic cylinder 35 is hinged to the side of the stabilizing plate frame 311 opposite to the support column 31; and the output end of the rotation adjustment hydraulic cylinder 35 is hinged to the first swing plate assembly.

[0050] When the rotation adjustment hydraulic cylinder 35 is activated, the output end of the rotation adjustment hydraulic cylinder 35 drives the first swing plate assembly to rotate, which in turn drives the support frame 32 to rotate, thereby causing the hook 34 on the support arm 33 to rotate accordingly, thus facilitating the lifting of heavy objects to the designated location.

[0051] Specifically, refer to Figure 1 In this embodiment, the height adjustment device includes a second swing plate assembly, a height adjustment frame 331, and a height adjustment hydraulic cylinder 36. The second swing plate assembly is mounted on one side of the support frame 32; the height adjustment frame 331 is mounted on the bottom side of the support arm 33 near the support frame 32; one end of the height adjustment hydraulic cylinder 36 is hinged to the second swing plate assembly, and the output end of the height adjustment hydraulic cylinder 36 is hinged to the height adjustment frame 331.

[0052] When the height adjustment hydraulic cylinder 36 is activated, the output end of the height adjustment hydraulic cylinder 36 drives the height adjustment frame 331 to rise and fall, which in turn drives the support arm 33 to rise and fall. This causes the hook 34 on the support arm 33 to also be adjusted accordingly, making it easier to lift and transport heavy objects to the designated location.

[0053] Specifically, refer to Figure 1 In this embodiment, the lifting device includes a drive motor 37, a hydraulic winch 38, a wire rope 381, and a guide wheel 332. The drive motor 37 is mounted on the side of the support arm 33 near the support frame 32; the hydraulic winch 38 is mounted on the top of the support arm 33, and its input end is connected to the output end of the drive motor 37; one end of the wire rope 381 is wound inside the hydraulic winch 38, and the other end extends forward along the top of the support arm 33 and is fixedly connected to the hook 34; the guide wheel 332 is rotatably mounted on the end of the support arm 33 away from the support frame 32, and the wire rope 381 abuts against the guide wheel 332, thereby effectively guiding and limiting the wire rope 381.

[0054] When the drive motor 37 is started, the output end of the drive motor 37 drives the hydraulic winch 38 to rotate, so that the hydraulic winch 38 unwinds or winds up the wire rope 381, thereby causing the wire rope 381 to loosen and lower or pull up the hook 34, so that the hook 34 can lift heavy objects.

[0055] More specifically, the rotation adjustment hydraulic cylinder 35, the height adjustment hydraulic cylinder 36, and the drive motor 37 are all electrically connected to the power control system 4, so that the power control system 4 can provide power to the rotation adjustment hydraulic cylinder 35, the height adjustment hydraulic cylinder 36, and the drive motor 37, thereby effectively and uniformly controlling the opening and closing of the rotation adjustment hydraulic cylinder 35, the height adjustment hydraulic cylinder 36, and the drive motor 37, and thus improving the automation level of the entire fertilizer spreader.

[0057] The travel control handle 45 is installed at the front of the driver's seat 44 and is connected to the dual hydraulic pump 43 to control its opening and closing. This allows the dual hydraulic pump 43 to control the forward or backward movement, speed adjustment, and steering of the left and right travel motors 223. A gear hydraulic pump 46 is connected in series with the dual hydraulic pump 43. This gear hydraulic pump 46 is connected to the rotation adjustment hydraulic cylinder 35, the height adjustment hydraulic cylinder 36, and the gate hydraulic cylinder 163, respectively, to provide hydraulic power to these cylinders.

[0059] Secondly, in this embodiment, the spreading system 5 is installed on the rear side of the fertilizer tank 11, and the spreading system 5 cooperates with the fertilizer discharge and conveying device.

The support plate frame 55 is installed on the side of the spreading frame 51 away from the fertilizer discharge auger sprocket 532; the fertilizer discharge motor 551 is installed on the bottom inner side of the support plate frame 55, and the fertilizer discharge motor 551 serves as the power source for the entire spreading drive mechanism, and the fertilizer discharge motor 551 is connected to the engine 42; the fertilizer discharge motor sprocket 552 is installed on the output end of the fertilizer discharge motor 551, and the fertilizer discharge motor sprocket 552 is located on the outer side of the support plate frame 55.

[0068] Meanwhile, the first rotating shaft 553 and the second rotating shaft 554 are respectively rotatably mounted on the outer side of the support plate frame 55; the first output diverter sprocket 5531, the second output diverter sprocket 5532 and the third output diverter sprocket 5533 are sequentially mounted on the first rotating shaft 553, and the first output diverter sprocket 5531 and the fertilizer discharge motor sprocket 552 are located on the same plane; the ratchet drive sprocket 5541 is mounted on the second rotating shaft 554, and the ratchet drive sprocket 5541 and the second output diverter sprocket 5532 are located on the same plane; the second fertilizer discharge auger sprocket 533 is mounted on the end of the fertilizer discharge auger shaft 53 away from the first fertilizer discharge auger sprocket 532, and the second fertilizer discharge auger sprocket 533 and the third output diverter sprocket 5533 are located on the same plane.

[0069] In addition, the fertilizer discharge motor output chain 555 is wound and engaged between the first output sprocket 5531 and the fertilizer discharge motor sprocket 552; the ratchet drive chain 556 is wound and engaged between the second output sprocket 5532 and the ratchet drive sprocket 5541; the power drive chain 557 is wound and engaged between the third output sprocket 5533 and the second fertilizer discharge auger sprocket 533; the fertilizer discharge speed regulating ratchet assembly is set on the outer side of the support plate frame 55, and the fertilizer discharge speed regulating ratchet assembly is simultaneously connected to the active conveying shaft 12 and the ratchet drive sprocket 5541, which not only facilitates the rotation of the active conveying shaft 12, but also effectively regulates the rotation speed of the active conveying shaft 12.

[0070] When the fertilizer discharge motor 551 is started, the output end of the fertilizer discharge motor 551 drives the fertilizer discharge motor sprocket 552 to rotate. Under the linkage of the fertilizer discharge motor output chain 555, the first output diverter sprocket 5531 is driven to rotate. The first output diverter sprocket 5531 drives the first rotating shaft 553, the second output diverter sprocket 5532 and the second output diverter sprocket 5532 to rotate simultaneously. Then, under the linkage of the power drive chain 557, the second fertilizer discharge auger sprocket 533 is driven to rotate, thereby driving the fertilizer discharge auger shaft 53 to rotate.

[0071] Simultaneously, under the linkage of the ratchet drive chain 556, the ratchet drive sprocket 5541 is driven to rotate. Then, under the linkage of the fertilizer discharge speed regulating ratchet assembly, the active conveyor shaft 12 is driven to rotate, so that the fertilizer discharge conveyor belt 14 can orderly transport the fertilizer in the fertilizer box 11. Then, the fertilizer discharge auger 531 effectively disperses and mixes the fertilizer on the fertilizer discharge conveyor belt 14, so that the fertilizer is dispersed to the dispensing area on the dispensing disc 521, thereby enabling the two dispensing discs 521 to perform fertilizer dispensing operations.

[0072] More specifically, refer to Figures 5-7 In this embodiment, the fertilizer discharge speed regulating ratchet assembly includes a ratchet 534, a ratchet drive shaft 5542, a ratchet drive rocker arm 1 5543, a ratchet drive rocker arm 2 535, a pawl 1 5351, a return spring 5352, a shift fork 536, a support column 56, a shift fork return spring 561, a support seat 57, a pawl 2 571, and a pawl 2 spring 58. The ratchet 534 is mounted on one end of the active conveying shaft 12 that extends outward from the bearing plate frame 55; the ratchet drive shaft 5542 is mounted on the ratchet drive sprocket 5541; the first ratchet drive rocker arm 5543 is movably sleeved on the ratchet drive shaft 5542; the second ratchet drive rocker arm 535 is sleeved on one end of the active conveying shaft 12, and the second ratchet drive rocker arm 535 is located on the side of the ratchet 534 away from the bearing plate frame 55, and the end of the first ratchet drive rocker arm 5543 away from the ratchet drive shaft 5542 and the end of the second ratchet drive rocker arm 535 away from the active conveying shaft 12 are hinged to each other.

[0073] Meanwhile, the pawl 5351 is rotatably mounted on the inner side of the ratchet drive rocker arm 535, and the pawl 5351 cooperates with the ratchet 534; one end of the return spring 5352 is connected to the pawl 5351, and the other end of the return spring 5352 is connected to the outer side of the ratchet drive rocker arm 535; the shift fork 536 is sleeved on one end of the active conveying shaft 12, one side of the shift fork 536 abuts against the pawl 5351, and a control handle 48 is provided on the outer side of the operating position 44. The control handle 48 is connected to one side of the shift fork 536 through a traction steel cable 481 to facilitate control of the position of the shift fork 536; specifically, the control handle 48 can control the ratchet assembly to have 4 positions, namely neutral and 3 fertilizer conveying positions.

[0074] The support column 56 is installed on the outside of the support plate frame 55; one end of the shift fork return spring 561 is connected to the top of the support column 56, and the other end of the shift fork return spring 561 is connected to one side of the shift fork 536; the support seat 57 is installed on the outside of the support plate frame 55; the second pawl 571 is rotatably installed on the support seat 57, and the second pawl 571 cooperates with the ratchet 534; one end of the second pawl spring 58 is connected to the bottom end of the second pawl 571, and the other end of the second pawl spring 58 is connected to the support seat 57.

[0075] When the ratchet drive sprocket 5541 rotates, the ratchet drive shaft 5542 and ratchet drive rocker arm 5543 work together to drive the ratchet drive rocker arm 535 to swing. This causes the pawl 5351 to push the ratchet 534, which in turn drives the active conveyor shaft 12 to rotate, thus enabling the fertilizer conveyor belt 14 to transport organic fertilizer in an orderly manner. Simultaneously, the position of the fork 536 can be controlled by the control handle 48. Changing the position of the fork 536 adjusts the number of teeth on the pawl 5351, thereby controlling the rotation angle of the ratchet 534. Ultimately, this allows for intermittent control of the conveying stroke of the fertilizer conveyor device each time the ratchet 534 is moved.

[0076] Furthermore, by setting a return spring 5352 between the shift fork 536 and the first pawl 5351, the shift fork 536 and the pawl can be stably maintained in their normal working positions. In addition, the second pawl 571 helps stabilize the ratchet 534, thus preventing it from losing control due to inertia at high speeds. Secondly, the intermittent rotation speed of the ratchet 534 is also related to the rotational speed of the exhaust motor 551 and is determined by the throttle position of the engine 42.

[0077] Specifically, refer to Figure 4 and Figure 5In this embodiment, the scattering guide mechanism includes a scattering guide plate 6, an adjusting strip 61, a fastener 62, and an adjusting member 63. One side of the scattering guide plate 6 is hinged to one side of the scattering basin frame 52; one end of the adjusting strip 61 is mounted on one side of the scattering basin frame 52 via the fastener 62, and the other end of the adjusting strip 61 is mounted on one side of the scattering guide plate 6 via the adjusting member 63. This coordinated arrangement of the adjusting strip 61, fastener 62, and adjusting member 63 effectively adjusts the angle and position of the scattering guide plate 6.

[0078] More specifically, the fastener 62 includes a fastening block installed on one side of the sprinkling basin frame 52. The fastening block has a fastening hole one, and the adjusting strip 61 has a fastening hole two at one end. Fastening bolts are inserted into both the fastening hole one and the fastening hole two, and fastening nuts are threaded onto the fastening bolts. In this way, the structure of the fastening bolts and fastening nuts working together can securely install one end of the adjusting strip 61 onto the fastening block.

[0079] More specifically, the adjusting component 63 includes an adjusting block installed on one side of the throwing guide plate 6, the adjusting block having an adjusting hole, and the other end of the adjusting strip plate 61 having an adjusting strip hole. Both the adjusting strip hole and the adjusting hole are fitted with a Phillips head bolt, and an adjusting nut is threaded onto the Phillips head bolt. In this way, the Phillips head bolt and the adjusting nut cooperate with each other to securely install the other end of the adjusting strip plate 61 onto the throwing guide plate 6.

[0080] In addition, by loosening the plum blossom knob bolt and adjusting nut together, and by loosening the fastening bolt and fastening nut together, the angle of the spreading guide plate 6 can be adjusted to control the angle and direction of fertilizer spreading.
