[0036] The rotary polishing component includes a funnel 18, a rotating shaft 19, and multiple push plates 20. The funnel 18 is vertically fixedly sleeved on the bottom end of the tube body 3, and a discharge port is opened on the front side.

The rotating shaft 19 is vertically arranged, and its upper and lower ends are respectively rotatably sleeved on the horizontal frame 31 and the bottom end of the funnel 18. Multiple push plates 20 are all vertically arranged and are uniformly fixedly installed in a ring on the outside of the rotating shaft 19. The rotating shaft 19 is connected to the main shaft 14 through a transmission mechanism.

[0037] The transmission mechanism includes a vertical shaft 21, a transmission shaft 22, a first gear set 23, a second gear set 27, and multiple sets of third gear sets 24. The vertical shaft 21 rotates vertically within a bracket 16 near the bucket body 1, and its top end is connected to the main shaft 14 via the first gear set 23. The transmission shaft 22 rotates horizontally inside the bottom side of the tube body 3 and passes through the crossbeam 31 at the top of the funnel cylinder 18. The bottom end of the vertical shaft 21 is connected to the end of the transmission shaft 22 via the second gear set 27.

[0038] The first gear set 23, the second gear set 27, and the multiple third gear sets 24 all consist of two meshing gears, which are fixedly sleeved on their respective shafts to achieve torque transmission.

[0039] The guide tube 25 is horizontally fixedly installed at the bottom end of the bucket body 1 and is connected to the inside of the bucket body 1. The guide tube 25 is also equipped with a pushing component. The housing 26 is fixedly installed in the middle of the bucket body 1. The end of the main shaft 14 in the guide tube 25 is rotatably sleeved in the housing 26. The first motor 28 is fixedly installed in the housing 26. The first motor 28 has two output ends. The ends of the two main shafts 14 that are close to each other are fixedly connected to the ends of the first motor 28 that are close to each other through a coupling. Multiple sets of rotary throwing components are symmetrically arranged at the bottom of the bucket body 1. The rotary throwing components at the bottom of the bucket body 1 are also connected to the pushing component in the guide tube 25 through a transmission mechanism. The top of the rotary throwing components in the bucket body 1 is connected to the inside of the bucket body 1. The spiral rollers 15 on both sides of the bucket body 1 rotate in opposite directions and are guided to both sides respectively. The end of the main shaft 14 in the bucket body 1 that is close to the first motor 28 is not equipped with a ball cage universal joint 143.

[0040] Both ends of the bucket body 1 are equipped with a pulling mechanism. The pulling mechanism includes a frame 29, a drum 30, a steel wire rope 38, and a second motor 32. The frame 29 is vertically fixedly installed on the upper side of the end of the bucket body 1. The drum 30 is rotatably sleeved inside the frame 29. The steel wire rope 38 is wound on the drum 30, and a locking buckle is fixedly installed at its end. The second motor 32 is fixedly installed on the outside of the frame 29, and its output end is fixedly connected to the end of the central shaft of the drum 30. A cover 33 is sleeved on the outermost tube 3. Pull rods 34 are symmetrically fixedly installed on the front and rear sides of the cover 33. The two pull rods 34 are embedded between the sealing block 8 and the second insert plate 6. A pull ring 35 is fixedly installed on the outer end of the cover 33. The wire rope 38 is fastened to the pull ring 35 via a lock. When the overall length of the equipment is too long, the lock on the wire rope 38 is fastened to the pull ring 35 on the outermost cover. Then, the second motor 32 drives the drum 30 to wind up the wire rope 38, making the wire rope 38 taut and pulling the entire tube 3 upward. This prevents the multiple tubes 3 from bending downward due to their own weight because they are too long, thus ensuring a horizontal state and covering the preset entire spreading width. The spreading mechanisms on both sides are made of lightweight materials. The pulling mechanism is selectively used according to the specific application. If the overall length of the equipment is too short and the rigidity is sufficient, the pulling mechanism is not required, and the wire rope 38 is wound up in the drum 30 for later use.

[0041] This device can be mounted on agricultural machinery via truss 2 and is powered by an agricultural vehicle battery. The entire device is controlled by an external remote control device. The circuit connections between related electrical devices and the control system are existing technologies and will not be described in detail here.

[0042] When using this equipment for fertilizer spreading, the overall effective spreading width of the equipment can be adjusted according to the area to be covered. The goal is to make the area width an integer multiple of the spreading width of the equipment in one pass, thereby reducing the number of back-and-forth operations and improving the efficiency of fertilizer spreading.

[0043] Based on the selection of the effective width, the overall effective width of the equipment is assembled. During assembly, the end of the tube body 3 with the sleeve 4 is connected to the outer end of the guide tube 25. First, the end of the main shaft 14 is inserted through the slot 141 and the shoulder 144, and then connected to the bolt 17 through the insertion hole 142 to achieve the connection of the main shaft 14. At the same time, the tube body 3 is kept in a horizontal state, so that the worm gear 12 and the worm 13 mesh. Under the self-locking action of the worm gear 12 and the worm 13, the tube body 3 remains in a horizontal state. Then, the two clamps 7 are respectively inserted into the round holes between the second insert plate 6 and the sealing block 8, and the screws 10 are tightened to achieve the connection of the plug-in components. Then, the protruding end of the sleeve 4 is inserted into the slot 301 to achieve the connection of the tube body 3 and the guide tube 25. The same operation is performed to connect two adjacent tube bodies 3 in sequence through the plug-in components, finally forming a horizontal spreading device, thereby achieving the preset one-time spreading width.

[0044] Motors 11 are connected in sequence through wire sockets to achieve circuit connection. Each motor 11 can operate independently under remote control command. The motor 11 on the outermost tube 3 does not need to be connected to the circuit, and the outer end of the outermost tube 3 is blocked by the cover 33.

[0045] After assembly, the fertilizer bag is placed in the inclined platform 36 and pierced by multiple spikes 37, opening the bottom side of the fertilizer bag so that the fertilizer falls into the bucket 1. The agricultural machinery moves, and at the same time the first motor 28 rotates, driving the main shaft 14 located in the bucket 1 to rotate through the coupling. The torque is transmitted through the ball cage universal joint 143 and bolt 17, so that multiple main shafts 14 rotate synchronously, driving the spiral roller 15 to rotate, so that the fertilizer is output to both sides. When it passes the upper side of the funnel 18, some fertilizer will leak downward and fall between multiple push plates 20.

[0046] The main shaft 14 rotates, which drives the vertical shaft 21 to rotate through the first gear set 23. The vertical shaft 21 drives the transmission shaft 22 to rotate through the second gear set 27. The transmission shaft 22 drives the corresponding rotating shaft 19 to rotate through multiple sets of third gear sets 24. The rotating shaft 19 drives multiple push plates 20 located on it to rotate, throwing out the fertilizer and realizing the spreading of fertilizer.

[0047] When an obstacle is encountered, the motor 11 near the obstacle is started by the remote control system, which drives the worm gear 13 to rotate. The worm gear 13 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the clamp 7 fixedly connected to it to rotate. The clamp 7 drives the tube body 3 to deflect and fold upward through the second insert plate 6. The sleeve 4 at the bend deforms elastically, and the ball cage universal joint 143 bends, so that the tube body 3 on the outside of the obstacle bends upward, making it easier to pass through the obstacle.

[0048] The operation of motor 11 allows the overall shape of the multiple tubes 3 to be adjusted according to the state of the obstacle.

[0049] During the seeding operation, the deflection mechanism keeps the pipe body 3 in a horizontal position. When encountering obstacles, it can adjust the overall shape of multiple pipe bodies 3 to allow them to pass through the obstacles without changing the direction of travel of the equipment, thus further ensuring work efficiency.

[0050] When the remaining area to be sown is smaller than the overall width of the equipment, the adjacent motors 11 rotate synchronously in opposite directions, causing the two adjacent tubes 3 to fold in a V-shape, thereby satisfying the width of the remaining area, avoiding repeated sowing, and ensuring the uniformity of sowing.

[0051] The first motor 28 can rotate in both directions, causing the fertilizer granules to move back and forth inside the tube 3 and flow out from the top of the funnel 18, so that the fertilizer is fully utilized.

[0052] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
