Description

Technical Field

[0001] This invention belongs to the field of forest pest and disease control pesticide spraying technology, and specifically relates to a pesticide spraying device for forest pest and disease control. Background Technology

[0002] Pests not only pose a significant threat to agricultural development, but also to the development of forestry ecology; therefore, it is necessary to carry out pesticide spraying for prevention or treatment of forest farms where pests or diseases have appeared or are about to appear.

[0003] A search revealed a forest pest and disease control spraying device with application number 202222021467.7. This device utilizes a servo motor, which, through the installation of various connecting components, drives a mounting plate to rotate back and forth around a mounting shaft, thereby rotating the sprayer and increasing its spraying area. However, the sprayer in this design cannot be adjusted in height. As a pesticide sprayer used in forests, spraying height is an indispensable function; only by adapting to the spraying conditions of forest tree height can the spraying effect against forest pests and diseases be better achieved.

[0004] A search revealed a forest pest and disease control spraying device with application number 202022711932.0. This device, equipped with a telescopic rod and a rotating mechanism, allows for adjustable spraying angles. The circular nozzle and fan teeth enable uniform spraying, achieving a more effective and even application compared to existing spraying devices, enhancing usability and facilitating pest and disease control in trees. However, this technical solution is primarily designed for shorter tree species. It is less effective for taller trees or those with large canopies. Furthermore, the conical barrel is difficult to insert into the tree canopy for spraying the inner branches and leaves. Additionally, the stirring method within the barrel can easily cause pesticide sedimentation. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pesticide spraying device for the prevention and control of forest pests and diseases. This device can reduce the sedimentation of pesticide solution. At the same time, the height of the spraying mechanism can be adjusted by the cooperation of the bearing mechanism and the telescopic rod. Furthermore, the spraying mechanism can be inserted into the tree canopy to spray pesticide solution, resulting in a more uniform spraying area.

[0021] The advantages of this invention compared to existing technologies are as follows:

[0022] 1) The main shaft is driven by motor I, which in turn drives rotating shaft I and rotating shaft II to rotate around the main shaft. Through the meshing of rack I and gear I, rotating shaft I and rotating shaft II rotate on their own axis, and drive the chain to rotate. The rotation of the chain causes the vertical plate and horizontal plate to move up and down, thereby causing the liquid at the bottom of the tank to surge to the top through the horizontal plate. At the same time, the support arm III on rotating shaft II supports the chain, so that the vertical plate on the chain pushes the liquid laterally. The spring pressure mechanism can control the tension of the chain in a timely manner. The use of horizontal and vertical plates not only realizes the up and down surge of the liquid, but also realizes the lateral stirring of the liquid, avoiding the sedimentation and stratification of the liquid, and causing the medicine in the liquid to settle to the bottom of the tank.

[0023] 2) The reciprocating screw in the storage mechanism drives the slider and water supply pipe to slide left and right in an orderly manner along the guide shaft II, thereby making the water supply pipe wind in an orderly manner and avoiding the situation of the water supply pipe being tangled.

[0024] 3) The roller II in the support mechanism II rotates through the spline shaft and spline sleeve, thereby driving the arc arm to climb or descend along the tree trunk, realizing the adjustment of the height of the telescopic rod and the spraying mechanism, and the spraying height is no longer limited to the height of the telescopic rod. At the same time, the support mechanism I is located on the upper and lower sides of the arc arm, which stabilizes the arc arm when the arc arm and the support mechanism II are climbing.

[0025] 4) The telescopic pole can be inserted into the dense tubes to spray the branches. The electric actuator III pushes the support sleeve II to move up and down along the telescopic pole, and the support rod I supports the support rod II. The support rods III and V spread out the branches at the top of the telescopic pole and around the spraying mechanism to achieve a good spraying field of view and range. Furthermore, the position of the support plate II is controlled by the motor V, thereby controlling the movement of the telescopic pole and the spraying mechanism, and can be adjusted and avoided when encountering large branches during the ascent.

[0026] 5) The spraying mechanism can control the alternating raising or lowering of the two ends of the adjusting arm through the adjusting mechanism, thereby driving the sealing plates at both ends of the adjusting arm to rise or fall alternately, so as to realize the alternating use of filter plate I and filter plate II; furthermore, the pore diameter on filter plate I is equal to 2-2.5 times the pore diameter on filter plate II, which can achieve the effect of adjusting the spraying volume according to different environments.

[0045] The drug supply mechanism 1 includes a tank body 11, a main shaft 12, a motor I 13, a chain 15, a rotating shaft I 16, a rotating shaft II 17, a spring-loaded mechanism 18, and a water pump 19. A set of racks I 111 is provided on the inner wall of the tank body 11. A water outlet 112 is provided at the bottom of the tank body 11 and connected to the water pump 19 via a pipe.

Two sets of rotating shafts I 16 are symmetrically arranged on the main shaft. On the main shaft 12, one end of the rotating shaft I16 is rotatably connected to the main shaft 12, and a set of sprockets is provided on the rotating shaft I16; two sets of chains 15 are provided and are respectively provided on the rotating shaft I16 and mesh with the sprockets; a horizontal plate 151 and a vertical plate 152 are provided on the chain 15; a set of rotating shafts II17 are provided and symmetrically arranged on both sides of the main shaft 12, one end of the rotating shaft II17 is rotatably connected to the main shaft 12, a support arm III172 is provided on the rotating shaft II17, a support shaft 173 is provided on the support arm III172 corresponding to the chain 15, and the support arm III172 corresponds to the chain 15; a gear I171 is provided at one end of the rotating shaft I16 at the top of the rotating shaft II17 and the main shaft 12 and meshes with a rack I111.

[0046] The spring-loaded mechanism 18 is located at one end of the main shaft 12.

This allows the sealing plates 65 at both ends of the adjusting arm 625 to rise and fall alternately, thus enabling the alternating use of filter plate I 66 and filter plate II 67. The adjusting plate I, in conjunction with the tension of the tension spring I, rotates to the other side.
