Description

Technical Field

[0001] This invention relates to the technical field, specifically to an adjustable directional spraying device for controlling pests and diseases in peach trees. Background Technology

[0002] The adjustable directional spraying device for peach tree pest and disease control is an intelligent plant protection device that can precisely adjust according to the shape and height of the peach tree canopy and the distribution of pests and diseases. Through a multi-angle adjustment mechanism, an air-assisted atomization system, and an intelligent control system, it achieves precise and directional spraying of pesticides, significantly improving pesticide utilization and reducing environmental pollution, making it an ideal choice for modern peach orchard plant protection.

[0003] Current traditional peach tree pest and disease control devices are insufficient to meet the needs of precise control and efficient operation. The core problems and subsequent technical improvement points are directly related as follows: Inaccurate orientation and fixed angle: They can only spray in one direction and cannot adjust the horizontal angle according to the position of peach tree branches and leaves; some rotatable devices cannot fix the angle, and are prone to deviation during spraying, resulting in pesticide waste and poor control effect; The pitch angle is not adjustable and the adaptability is poor: The pitch angle of the spray gun is fixed and cannot be adapted to the different heights of peach tree branches, making it difficult to cover pests and diseases at high or low places. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable directional spraying device for controlling peach tree diseases and pests, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable directional spraying device for controlling peach tree diseases and pests, comprising a control box, a rotating cylinder rotatably connected to the upper side of the control box, a rotating rod slidably connected to the inside of the rotating cylinder, a locking gear fixedly connected to the lower part of the rotating rod, upper and lower tooth grooves respectively provided in the lower part of the rotating cylinder and the lower side of the control box to engage with the locking gear, an external toothed ring fixedly connected to the outer side of the lower part of the rotating cylinder, a power gear meshing with one side of the external toothed ring, a connecting frame fixedly connected to the upper side of the control box, a motor fixedly connected to the upper part of the connecting frame, the power end of the motor penetrating the connecting frame and fixedly connected to the power gear, a mounting frame fixedly connected to the upper part of the rotating rod, two sets of rotating shafts rotatably connected inside the mounting frame, a spray gun fixedly connected between the rotating shafts, and a water inlet pipe fixedly connected to the rear side of the spray gun.

[0006] Preferably, the rotating cylinder has a lifting groove inside, a lifting plate is fixedly connected to the outside of the rotating rod, the lifting plate is slidably connected inside the lifting groove, and a first spring is fixedly connected to the lower side of the lifting groove, the first spring being sleeved on the outside of the rotating rod.

[0007] Preferably, two sets of shielding brackets are slidably connected to the lower outer side of the control box, and the shielding brackets on both sides are provided with arc-shaped holes for cooperating with the rotating rod on one side.

[0008] Preferably, a connecting box is fixedly connected to one side of the lower part of the control box, a reversing gear is rotatably connected to the middle of the connecting box, a rack is meshed with the upper and lower sides of the reversing gear, a connecting strip is fixedly connected to one side of the rack, the connecting strip penetrates the connecting box and is fixedly connected to a connecting block, and the connecting block is fixedly connected to the shielding frame.

[0009] Preferably, a limiting groove is provided on one side of the control box, and a guide rod is fixedly connected inside the limiting groove. Limiting blocks are fixedly connected to opposite sides of the two shielding frames. The limiting blocks are slidably connected to the outside of the guide rod. A second spring is fixedly connected between the limiting blocks and the limiting groove, and the second spring is sleeved on the outside of the guide rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. When the locking gear meshes with the upper tooth groove, the motor drives it to rotate back and forth, efficiently covering the peach tree canopy; when it meshes with the lower tooth groove, the angle is precisely fixed, allowing for spraying of specific pests and diseases. Switching between the two modes requires no tools, making it suitable for both large-area and precision control scenarios, thus improving pesticide utilization. 2. This invention allows for adjustable spray gun tilt angles within a certain range, and the locking ring engages with the locking groove to ensure secure positioning. It is suitable for all-around spraying of peach trees from the roots and branches to the top of the canopy, solving the problem of traditional devices failing to cover high or low areas of pests and diseases, thus improving the overall pest control coverage. 3. This invention utilizes the coordinated action of a reversing gear and a rack, with the two side shielding frames moving synchronously. The second spring, in its normal state, pulls the shielding frame to block the lower tooth groove, preventing the locking gear from accidentally disengaging due to spray vibration. The arc-shaped hole fits the rotating rod, ensuring uninterrupted shielding and improved locking reliability, thus guaranteeing precise directional spraying. Attached Figure Description
