[0039] The swinging mechanism 30 comprises a sliding rod 302 fixedly connected to the lower surface of the base 10, a moving plate 303 slidably sleeved outside the sliding rod 302, and a roller 306 fixedly connected to one end of the moving plate 303.

[0040] The sliding rod 302 is further slidably sleeved with a reset spring 304, the reset spring 304 is located between the base 10 and the moving plate 303, and the sliding rod 302 is fixedly connected with a limiting block 307 at the end away from the base 10.

[0041] The swinging mechanism 30 further comprises an L-shaped rod 301 fixedly connected to one end of the horizontal plate 205, the horizontal section of the L-shaped rod 301 is in rolling connection with the roller 306, the transmission shaft 202 is further fixedly connected with an eccentric wheel 305 outside, and the eccentric wheel 305 is in rolling connection with the moving plate 303.

[0042] Specifically, during the forward movement of the base 10, the moving wheels 201 drive the transmission shafts 202 to rotate, one of the transmission shafts 202 drives the eccentric wheel 305 to rotate, the eccentric wheel 305 presses the moving plate 303, the moving plate 303 moves along the outer part of the slide rod 302 to the direction close to the lower surface of the base 10, and the moving plate 303 drives the roller 306 to move during the movement, the roller 306 drives the L-shaped rod 301 to rotate upward, the L-shaped rod 301 drives the horizontal plate 205 to rotate on the mounting seat 204, the moving plate 303 compresses the return spring 304 during the movement, and the elastic force of the return spring 304 drives the moving plate 303 to move away from the base 10 when the eccentric wheel 305 is separated from the moving plate 303. At this time, the deflected horizontal plate 205 rotates downward under the action of gravity, the rotation of the moving wheels 201 drives the horizontal plate 205 to reciprocate up and down, thereby driving the spray head 206 to reciprocate up and down synchronously, the transmission shaft 202 drives the eccentric wheel 305 to drive the moving plate 303 to reciprocate, the L-shaped rod 301 drives the horizontal plate 205 and the spray head 206 to reciprocate up and down, so that the spray head 206 continuously performs lateral sweeping and spraying during the movement of the equipment, further expands the wetting area, avoids the local drought or water accumulation problem caused by the traditional fixed spray head 206, adapts to different planting intervals of grapes, and improves the uniformity of spraying.

[0043] The protection mechanism 40 includes a mounting rod 401 fixedly connected to the top of the mounting seat 204, a containing cavity 402 is formed in the side surface of the mounting rod 401, a moving rod 403 is slidably connected in the containing cavity 402, a supporting rod 405 for pushing the grapevine away is fixedly connected to the end of the moving rod 403 away from the mounting rod 401, the front part of the supporting rod 405 is bent to the direction close to the base 10, a pressing spring 404 is further fixedly connected in the containing cavity 402, one end of the pressing spring 404 is fixedly connected with the containing cavity 402, and the other end of the pressing spring 404 is fixedly connected with the moving rod 403.

[0044] Specifically, when the base 10 advances, the curved front end of the support rod 405 pushes some small grapevines outward to avoid entanglement of the spray head 206, and when a thicker grapevine is encountered, the support rod 405 is pressed to move into the accommodating cavity 402 of the mounting rod 401, and the compression spring 404 is compressed. When the support rod 405 is separated from the thicker grapevine, the elastic force of the compression spring 404 pushes the moving rod 403 and the support rod 405 to move outward to reset. The support rod 405 structure with the compression spring 404 buffer is arranged on the top of the mounting seat 204. When the base 10 advances, the arc-shaped part of the front end of the support rod 405 can gently push the grapevines on both sides away. When a thick vine is encountered, the support rod 405 automatically retracts to absorb the impact. After passing the obstacle, the compression spring 404 resets to avoid mechanical damage and interruption of work, thereby ensuring that the bottom of each grapevine is covered with water and further improving the spraying range.

[0045] The support mechanism 50 includes a push rod 501 fixedly connected to the end of the rotating rod 203 away from the mounting seat 204, a hinged seat 502 rotationally connected to the end of the push rod 501 away from the rotating rod 203, a bidirectional screw rod 503 threadedly connected between the two hinged seats 502, and a knob 504 fixedly connected to one end of the bidirectional screw rod 503.

[0046] Specifically, when the distance between the spray heads 206 on both sides of the base 10 needs to be adjusted, the bidirectional screw rod 503 is driven to rotate synchronously by rotating the knob 504, and the bidirectional screw rod 503 drives the two hinged seats 502 to move away from or close to each other during rotation. When the two hinged seats 502 move away from each other, the two hinged seats 502 drive the rotating rod 203 to rotate outward from the base 10 through the push rod 501, thereby increasing the distance between the spray heads 206 on both sides of the base 10. When the two hinged seats 502 move close to each other, the two hinged seats 502 drive the rotating rod 203 to rotate toward the base 10 through the push rod 501, thereby reducing the distance between the spray heads 206 on both sides of the base 10. The knob 504 on the bidirectional screw rod 503 can drive the two hinged seats 502 to move toward or away from each other along the screw rod axis, thereby driving the push rod 501 to drive the rotating rods 203 on both sides to swing synchronously, achieving precise control of the unfolding angle of the telescopic mechanism 20. This structure ensures that the left and right spray heads 206 are symmetrically and synchronously stretched or contracted, avoids structural deformation or spraying deviation caused by uneven force on one side, enables the spray heads 206 to accurately cover the target area, and improves the uniformity and controllability of fertilization and watering.

[0047] The base 10 is fixedly connected with a mounting frame 601 at the front, and the mounting frame 601 is rotationally connected with a rotating shaft 602 at the end away from the base 10. The rotating shaft 602 is fixedly connected with a plurality of rotating rods 603 in a ring shape outside.

[0048] The rotating shaft 602 is further fixedly connected with a first pulley 604, and the other transmission shaft 202 is fixedly connected with a second pulley 605, and the second pulley 605 and the first pulley 604 are drivingly connected through a synchronous belt 606.

[0049] In particular, when the base 10 advances, the other transmission shaft 202 drives the second pulley 605 to rotate, the first pulley 604 is driven to rotate through the synchronous belt 606, the rotating shaft 602 is driven to rotate by the first pulley 604, the rotating rod 603 is rotated at the front of the base 10 by the rotating shaft 602, and the rotating power of the transmission shaft 202 is efficiently transmitted to the front rotating shaft 602 through the synchronous belt 606, so that the multiple rotating rods 603 distributed in a ring shape rotate at high speed, and the mechanism can automatically remove fallen leaves, weeds, gravel and other field sundries in front of the path during the advance of the base 10 along the grape row, effectively preventing impurities from being accumulated in front of the equipment or being wound into the area of the moving wheel 201 and the spray head 206, not only ensuring smooth passage of the equipment, avoiding running obstruction caused by blockage or winding, but more importantly, preventing sundries from adhering or shielding the outlet of the spray head 206, ensuring that the water and fertilizer solution can be continuously, stably and uniformly sprayed to both sides, improving the coverage rate and operation quality of irrigation and fertilization. At the same time, the rotating obstacle removal function completely relies on the self-power driving of the equipment during walking, without additional energy consumption, realizing passive automatic cleaning, significantly reducing the frequency of manual cleaning and maintenance cost, and improving the intelligent level and field adaptability of the device.

[0050] Working principle:

[0051] The distance between the spray heads 206 in the telescopic mechanism 20 is adjusted through the supporting mechanism 50, so as to adapt to different planting distances of grapes, thereby ensuring that the root area of the grape plant is evenly watered and fertilized, reducing resource waste, and at the same time, in a non-working state or when passing through a narrow area, the telescopic mechanism 20 can fold the spray heads 206 close to the base 10, reducing the overall width of the equipment, facilitating passage in dense grape rows, and then pushing the base 10 forward through the moving wheel 201, in the advancing process, the horizontal plate 205 and the spray head 206 are swung up and down through the swinging mechanism 30, so that the spray head 206 continuously swings laterally during the advance of the equipment, further expanding the wetting area, avoiding the local drought or water accumulation problem caused by the traditional fixed spray head 206, adapting to different planting distances of grapes, improving the uniformity of spraying, and at the same time, avoiding mechanical damage and work interruption through the protection mechanism 40, so as to ensure that the bottom of each grapevine is covered with water, further improving the spraying range, and the rotating power of the transmission shaft 202 is efficiently transmitted to the front rotating shaft 602 during the advance of the base 10, so as to drive the multiple rotating rods 603 distributed in a ring shape to rotate at high speed, and the mechanism can automatically remove fallen leaves, weeds, gravel and other field sundries in front of the path during the advance of the base 10 along the grape row.
