[0033] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed account of the agricultural machinery fertilization device with adjustable fertilization distance according to this utility model.

[0034] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] See Figures 1-5 This embodiment of the agricultural machinery fertilization device with adjustable fertilization distance allows for flexible adjustment of the fertilization distance and range, ensuring that fertilizer is applied to the appropriate area, reducing fertilizer waste, and improving fertilizer utilization. It is also adaptable to different types and growth stages of crops, enhancing the equipment's application range and adaptability. Furthermore, it ensures uniform distribution of fertilizer within the hopper 1, avoiding blockages and partial fertilizer shortages caused by fertilizer accumulation, improving continuous operation capability, and thus enhancing overall operational efficiency. In this embodiment, it mainly includes a hopper 1, which is a long trough-shaped device with an open top. At least one limiting rod 6 is fixedly installed on the back of the hopper 1. A limiting bolt 7 is threaded through the limiting rod 6 in the front-to-back direction. A pressing plate 8 is rotatably installed at the end of the limiting bolt 7, and a rubber pad 9 is fixedly installed at the end of the pressing plate 8. When using the device, the hopper 1 can be placed on the rear panel of a tricycle or other household vehicle and limited by the limiting rod 6. It is then fixed by the limiting bolt 7. During this process, the rubber pad 9 provides shock absorption and protection. At least one partition 10 is fixedly installed inside the hopper 1, with the end of the partition 10 located in the middle of the hopper 1 inclined downwards. The partition 10 blocks the interior of the hopper 1, preventing hands from accidentally entering the hopper 1.

[0036] To adjust the width of the fertilizer application. See also Figure 4 and Figure 5 In this embodiment, a feeding trough 2 is provided at the bottom of the hopper 1, and a feeding pipe 3 that can slide within the feeding trough 2 is provided at the bottom end of the hopper 1. A baffle 11 is fixedly provided at the top end of the feeding pipe 3. The baffle 11 can slide along the length direction of the feeding trough 2, and each baffle 11 is staggered and stacked. The baffles 11 cooperate to block the feeding trough 2. The staggered baffles 11 ensure that the feeding pipe 3 always blocks the feeding trough 2 when it moves. A sliding plate 12 that can be inserted into the feeding trough 2 is fixedly provided on the side of the feeding pipe 3. A lead screw 13 is horizontally rotatably provided inside the feeding hopper 1, and a bidirectional motor 14 that drives the lead screw 13 to rotate is fixedly provided on the side of the hopper 1. When it is necessary to change the fertilizer spreading width, the bidirectional motor 14 is controlled to work, driving the lead screw 13 to rotate, thereby moving the sliding plate 12 within the feeding trough 2.

[0037] The lead screw 13 includes a bidirectional screw 131 with both ends threadedly connected to the corresponding sliding plate 12. A first screw 132 is coaxially fixed at both ends of the bidirectional screw 131, and each first screw 132 is threadedly connected to the corresponding sliding plate 12. The thread direction of the first screw 132 is the same as the thread direction at the end of the corresponding bidirectional screw 131, and the pitch of the first screw 132 is greater than the pitch at the end of the corresponding bidirectional screw 131. The bidirectional screws 131 cause the corresponding sliding plates 12 to slide relative to each other. By using the bidirectional screws 131 and the first screws 132 with different pitches, different speeds of movement of the sliding blocks are achieved, thereby changing the relative position of each feed tube 3.

[0038] To change the fertilization distance, see [reference needed] in this embodiment. Figures 1-4 Below the hopper 1, an adjustable fertilization area variable-pitch module 4 is installed. The variable-pitch module 4 includes a bellows 41 fixedly installed at the rear end of the hopper 1, a horizontally rotatable impeller 42 inside the bellows 41, and a first motor 43 fixedly installed on the side of the bellows 41 to drive the impeller 42. An air inlet 44 is opened on the side of the bellows 41, and an air outlet 45 is opened at the bottom of the bellows 41. The air outlet 45 has a constricted structure and its opening faces the bottom outlet of the discharge pipe 3. When the hopper 1 is discharging fertilizer, the first motor 43 can be controlled to work according to the actual situation, driving the impeller 42 to rotate, thereby drawing air from the air inlet 44 and discharging it through the air outlet 45 to apply power to the fertilizer falling from the discharge pipe 3, increasing the fertilizer spreading range.

[0039] The variable pitch module 4 also includes a mounting bracket 46 fixedly mounted at the bottom of the fan. An electric actuator 47 is hinged to the bottom end of the mounting bracket 46, and a base plate 48 is hinged to the telescopic end of the electric actuator 47. The other end of the base plate 48 abuts against the mounting bracket 46. The hinged end of the base plate 48 is inclined downwards, and a baffle 49 is horizontally fixed to the top of the hinged end. Guide plates 50 are fixedly mounted on both sides of the bottom of the discharge pipe 3. An adjusting plate 51 is hinged to the end of the guide plate 50, and an adjusting bolt 52 is threaded onto the top of the adjusting plate 51. During discharge, the fertilizer discharged from the discharge pipe 3 falls onto the base plate 48, which is located between the guide plates 50 and the mounting bracket 46. The fertilizer moves downwards on the base plate 48 after passing through the guide plates 50, creating a splashing effect when passing the baffle 49, causing collisions between the fertilizer particles and thus changing the spreading range and uniformity. During this process, the electric actuator 47 can be controlled to change the angle of the base plate 48 according to the actual situation, and the position of the adjusting plate 51 can be changed by rotating the adjusting bolt 52 to change the fertilizer spreading range.

[0040] To ensure even distribution of fertilizer during spreading. See details. Figure 4 The hopper 1 has a horizontally fixed balancing unit 5 for balancing fertilizer height. The balancing unit 5 includes at least two horizontally rotating augers 501 arranged opposite each other, with opposite rotation directions. A second motor 502 is fixedly mounted on the side of the hopper 1 to drive the corresponding auger 501. During feeding, the second motor 502 is controlled to rotate, causing the corresponding auger 501 to move back and forth inside the hopper 1, ensuring uniform distribution of fertilizer within the hopper 1. This avoids blockages and material shortages caused by fertilizer accumulation, improves continuous operation capability, and thus enhances overall operational efficiency.

[0041] The method of using the agricultural machinery fertilization device with adjustable fertilization distance of this utility model is as follows: First, when using the device, the hopper 1 can be placed on the rear panel of a tricycle or other household vehicle and limited by the limiting rod 6. Then, it is fixed by the limiting bolt 7. During feeding, the fertilizer discharged from the feeding pipe 3 falls onto the base plate 48, which is located between the guide plate 50 and the mounting frame 46. The fertilizer moves downward on the base plate 48 after passing through the guide plate 50, and splashes when passing through the baffle 49, causing collisions between fertilizer particles, thereby changing the spreading range and the uniformity of spreading. At the same time, the second motor 502 is controlled to work, driving the corresponding auger 501 to rotate, causing the fertilizer inside the hopper 1 to move back and forth, thereby ensuring the uniform distribution of fertilizer in the hopper 1, avoiding blockages caused by fertilizer accumulation and the problem of insufficient fertilizer in certain areas, improving the ability of continuous operation, and thus improving the overall operating efficiency.

[0042] During this process, the electric actuator 47 can be controlled to change the angle of the base plate 48 according to the actual situation. Simultaneously, the adjusting bolt 52 can be rotated to change the position of the adjusting plate 51, thereby altering the fertilizer spreading range. At the same time, the first motor 43 can be controlled to drive the impeller 42 to rotate, thus drawing air from the air inlet 44 and discharging it through the air outlet 45, applying power to the fertilizer falling from the feed pipe 3 and increasing the fertilizer spreading range. Furthermore, the bidirectional motor 14 can be controlled to drive the lead screw 13 to rotate, causing the sliding plate 12 to move relative to the feed trough 2, changing the fertilizer spreading width.

[0043] During this process, the partition 10 blocks the inside of the hopper 1 to prevent hands from accidentally entering the hopper 1.
