Description

Technical Field

[0001] The utility model relates to the technical field of pesticide sprayers, in particular to a pesticide sprayer for preventing and controlling plant diseases and insect pests in forestry. Background Art

[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forests to play a protective role. It is an important part of the national economy. In the human and biosphere, forestry is engaged in the cultivation, protection, and utilization of forest resources through advanced science and technology and management methods to give full play to the multiple benefits of forests.

[0003] In Chinese Patent 202320047150.2, the utility model relates to the field of spraying technology, and discloses a forestry pest control sprayer, including a vehicle body, a traveling mechanism and a spraying mechanism; the traveling mechanism includes a fourth support plate arranged on both sides of the vehicle body, the ends of the fourth support plate are rotatably connected to the rotating shaft, the ends of the rotating shaft are provided with traveling wheels, and the side of the vehicle body close to the ground is provided with a jacking assembly for pushing one end of the vehicle body to lift up; the spraying mechanism includes a first support plate arranged at one end of the vehicle body, the end of the first support plate is provided with a main shaft that rotates synchronously with the rotating shaft, and the end of the main shaft close to the center of the vehicle body is fixedly connected to a medicine tank. The utility model is applicable to a forestry pest control sprayer, and by providing a medicine tank that rotates synchronously with the traveling wheel, the entire sprayer is continuously rotated during the movement of the medicine tank to achieve the mixing of the internal liquid medicine, thereby avoiding the concentration of the liquid medicine at different depths, so that the effect of spraying is better.

[0004] The existing forestry pest control sprayers have the problem that the height of their spray rods cannot be adjusted. For some lower trees, the spray rod is too high and easily scratches the branches and affects the movement. For some higher trees, the spray rod is too low and easily causes the medicine to not be sprayed on the branches and leaves. In addition, when adding medicine to the medicine storage tank, the person is in the forest farm. During the adding process, some impurities such as leaves may float into the medicine storage tank through the adding port. During the spraying process, as the medicine liquid moves forward, it will block the medicine delivery pipeline or nozzle. In addition, the pesticides used in forestry pest control are harmful to the human body. During the spraying process, the mist-like medicine liquid sprayed outwards is easy to fall on the operator during the falling process, causing harm to him. In addition, some sprayers use drones to spray trees from above or from the side of the trees for prevention and control. However, the vast majority of pests like to hide under the branches and leaves. When spraying from above or from the side, it is blocked by the branches and leaves, and it is difficult for the medicine liquid to directly contact the pests and diseases, affecting the prevention and control effect.

[0005] Therefore, a forestry pest control spraying machine is proposed in view of the above problems. Utility Model Content

[0006] In order to make up for the shortcomings of the existing technology, the problem that the height of the spray rod of the existing forestry pest control sprayer cannot be adjusted is solved. For some lower trees, the spray rod is too high and it is easy to scratch the branches and affect the movement. For some higher trees, the spray rod is too low and it is easy to cause the medicine to not be sprayed on the branches and leaves. Sometimes, when adding medicine to the medicine storage tank, it is in the forest farm. During the adding process, some impurities such as leaves may float into the medicine storage tank through the adding port. During the spraying process, as the medicine liquid moves forward, it will block the medicine delivery pipeline or nozzle. The pesticides used in forestry pest control are harmful to the human body. During the spraying process, the mist liquid sprayed outward is easy to fall on the operator during the falling process, causing harm to him. Some sprayers use drones to spray trees from above or on the sides of the trees for prevention and control. However, the vast majority of pests like to hide under the branches and leaves. When spraying from above or on the side, it is blocked by the branches and leaves, and the medicine liquid is difficult to directly contact the pests and diseases, affecting the prevention and control effect.

[0027] like Figure 1 As shown, a forestry pest control sprayer includes a sprayer mobile frame 1, a medicine spraying assembly 2 is installed at one end of the sprayer mobile frame 1, and a medicine storage box assembly 3 is arranged on the top of the sprayer mobile frame 1, and a push handle 4 is fixedly connected to the other end of the sprayer mobile frame 1, and a protective cover 5 is arranged outside the push handle 4.

[0028] like Figure 3 and Figure 4 As shown, a forestry pest control sprayer, the drug spraying assembly 2 is used to adjust the spraying height, the height adjustment lifting cylinder 204 forms a rotating structure with the lifting nut 206 through the rotating ring 205, and the lifting nut 206 is threadedly connected to the threaded column 201, the height adjustment lifting cylinder 204 forms a sliding structure with the threaded column 201 through the limiting slider 203, the limiting slide groove 202, and the threaded column 201, and the limiting slide groove 202 is symmetrically arranged with respect to the vertical center axis of the threaded column 201. The high-pressure atomizing nozzle 208 is arranged at equal intervals with respect to the top of the spraying rod 207, and the spraying rod 207 is symmetrically arranged with respect to the vertical center axis of the height adjustment lifting cylinder 204. There are two high-pressure atomizing nozzles 208, and a connecting structure is formed between the spray rod 207 and the medicine delivery hose 209. By rotating the lifting nut 206, the height-adjusting lifting cylinder 204 can be raised and lowered, so that the spray rod 207 and the high-pressure atomizing nozzle 208 at the top can be adjusted in height, so that it can be suitable for trees of different heights and the sprayed liquid can be better attached to the branches and leaves of the trees. At the same time, the high-pressure atomizing nozzle 208 is set to face upward, and the trees are sprayed from bottom to top for prevention and control, so that the liquid medicine can be sprayed to the bottom of the branches and leaves, so that the pests hidden at the bottom can be disinfected, thereby improving the prevention and control efficiency.

[0029] like Figure 5As shown, a forestry pest control sprayer, the medicine storage box assembly 3 is used to store and stir the liquid medicine, the reduction motor 307 forms a transmission structure with the second pulley 306, the transmission belt 305, the first pulley 304 and the stirring shaft 302, the stirring blade 303 is arranged at an equal angle with respect to the outer wall of the stirring shaft 302, the threaded sealing cover 310 and the dosing nozzle 308 form a threaded detachable structure, and the dosing nozzle 308 and the protective filter cartridge 309 form a snap-fit ​​structure, the dosing nozzle 308 and the forestry sprayer storage tank 301 form a connecting structure, and the inner cavity of the forestry sprayer storage tank 301 is connected through the drainage.
