Description
Technical Field
[0001] The utility model relates to the technical field of a pesticide spraying rack for a plant protection machine, in particular to a pesticide spraying rack for a plant protection machine. Background Art
[0002] Plant protection drones, also known as "plant protection drones" or "agricultural drones," are unmanned aerial vehicles used for agricultural plant protection. Equipped with spraying equipment and advanced sensor systems, they utilize automated flight and precision spraying technology and are widely used in agricultural operations such as pest control, fertilization, and weeding. Plant protection drones play a vital role in modern agriculture, significantly improving operational efficiency, reducing fertilizer and pesticide waste, and enabling them to accomplish tasks in harsh environments that are difficult for traditional agricultural machinery to accomplish.
[0003] However, in the existing technology, the pesticide spraying nozzle and the spray frame are fixed with bolts. According to Newton's third law, the sprayed liquid will generate a reaction force opposite to the spraying direction. This reaction force will act on the nozzle and the drone body, causing the nozzle to shake or the body to be unstable. The reaction force generated when the nozzle is working will be directly transmitted to the spray frame, affecting the stability and comfort of the flight, and the user experience is poor. Utility Model Content
[0004] The purpose of the utility model is to solve the technical problem that in the prior art, the nozzle and the spraying frame for spraying pesticides are fixed by bolts. According to Newton's third law, the sprayed liquid will generate a reaction force opposite to the spraying direction. This reaction force will act on the nozzle and the drone body, causing the nozzle to shake or the body to be unstable. The reaction force generated when the nozzle is working will be directly transmitted to the spraying frame, affecting the stability and comfort of flight and resulting in a poor user experience. A spraying frame for a crop protection machine is proposed.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a spray rack for a crop protection machine, comprising a bottom frame, the upper surface of the bottom frame is fixedly connected to a medicine storage box, the lower surface of the bottom frame is fixedly connected to a connecting piece, one side surface of the connecting piece and one side surface of the bottom frame are embedded with a linear bearing, the inner wall surface of the linear bearing is embedded with a medicine outlet pipe, one end of the medicine outlet pipe is connected to a nozzle, the other end of the medicine outlet pipe is connected to a hose, one end of the hose is connected to a water pump, the input end of the water pump is connected to the lower surface of the medicine storage box, the outer surface of the medicine outlet pipe is sleeved with a spring, the outer surface of the medicine outlet pipe is fixedly connected to a support piece, one side surface of the support piece is fixedly connected to two dampers, one end of the two dampers are fixedly connected to a support block, and the upper surface of the support block is fixedly connected to the lower surface of the medicine storage box.
[0006] Furthermore, an adjusting ring is provided at one end of the spring, and the inner wall surface of the adjusting ring is threadedly connected to the outer surface of the medicine outlet tube.
[0007] Furthermore, one end of the spring is fixedly connected to a bidirectional bearing, and one side surface of the bidirectional bearing is fixedly connected to one side surface of the adjusting ring.
[0008] Furthermore, a visual window is provided on the outer surface of the medicine storage box, and transparent glass is embedded in the visual window.
[0009] Furthermore, a scale is provided on the outer surface of the transparent glass.
[0010] Furthermore, the connecting piece is integrally formed with the bottom frame.
[0011] Compared with the prior art, the advantages and positive effects of the present invention are:
[0012] 1. In the utility model, when in use, the water pump medicine liquid is drawn out from the inside of the medicine storage box, and then atomized and sprayed out from the nozzle through the hose and the medicine outlet pipe. The reaction force generated during the spraying process will push the medicine outlet pipe through the nozzle. After the medicine outlet pipe is subjected to force, it slides inside the linear bearing, squeezing the spring and the damper. The damper and spring compress the stroke, absorb kinetic energy, and provide buffering. When the reaction force decreases, the spring and damper linearly reset, reducing the impact of the force on the nozzle, and can reduce the impact of the reaction force on the drone body, thereby improving the stability and comfort of the flight.
[0013] 2. In the utility model, the adjusting ring is rotated, and under the action of the thread, the adjusting ring moves back and forth, squeezing or releasing the spring, and adjusting the stroke of the spring as needed. The bidirectional bearing avoids friction between the spring and the adjusting ring when the adjusting ring rotates, ensuring the service life of the parts. The amount of medicine liquid retained can be observed through the visual window and transparent glass opened on the outer surface of the medicine storage box, and replenished in time. The amount of medicine liquid inside the medicine storage box can be intuitively observed through the scale to avoid too much or too little medicine liquid. The connecting parts and the bottom frame are integrated to improve the stability and strength of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In this embodiment, when in use, the water pump 14 draws medicine from the inside of the medicine storage box 2, and then passes through the hose 13 and the medicine outlet pipe 4 and is sprayed out by the nozzle 5 after being atomized. The reaction force generated during the spraying process will push the medicine outlet pipe 4 through the nozzle 5. After being subjected to the force, the medicine outlet pipe 4 slides inside the linear bearing 15, squeezing the spring 16 and the damper 11. The damper 11 and the spring 16 compress the stroke, absorb kinetic energy, and provide buffering. When the reaction force decreases, the spring 16 and the damper 11 linearly reset, reducing the impact of the force on the nozzle 5, and can reduce the impact of the reaction force on the drone body, thereby improving the stability and comfort of the flight.

After the medicine outlet pipe 4 is subjected to force, it slides inside the linear bearing 15, squeezing the spring 16 and the damper 11. The damper 11 and the spring 16 are compressed. The spring 16 and the damper 11 are linearly reset, and the adjusting ring 9 is rotated. Under the action of the thread, the adjusting ring 9 moves back and forth, squeezing or releasing the spring 16, and the stroke of the spring 16 is adjusted as needed.
