Abstract
Description
Technical Field
[0001] This utility model relates to the field of forest pest and disease spraying technology, and more specifically, to a spraying device for the prevention and control of forest pests and diseases. Background Technology
[0002] Spraying is essential for the control of forest pests and diseases. Forests are the core of the ecosystem; the spread of pests and diseases can damage biodiversity, lead to forest decline, and weaken their functions such as carbon sequestration and water conservation. Economically, pests and diseases reduce timber and economic forest products, directly impacting the forestry industry. For example, pine wilt disease can rapidly destroy pine forests, and leaf-eating pests can reduce timber production by more than 30%. In addition, some pests and diseases can spread to cities and farmland, affecting human lives. Scientific spraying can quickly control pests and diseases, balancing pest control with environmental protection, and is a key means of ensuring the ecological, economic, and social benefits of forests.
[0003] An investigation revealed that Chinese utility model patent CN217695028U discloses a spraying device for controlling forest pests and diseases. The device includes a vehicle body, a pesticide storage tank and handrail fixedly mounted on the upper part of the vehicle body, a stirring mechanism inside the storage tank for mixing the pesticide solution, a pump body installed on the side wall of the storage tank, and a liquid guide pipe connected to the pump body's outlet. A spraying assembly connected to the liquid guide pipe at the upper end of the storage tank for rotating spraying is also included. This spraying device, through its stirring mechanism and the corresponding spraying assembly, can achieve multi-directional spraying from the nozzle. While this spraying device can prevent pesticides from being sprayed onto operators during spraying, thus improving spraying efficiency and providing safety protection, when the target pests are longhorn beetles or other trunk-boring insects, the circular spraying method results in only a small portion of the pesticide landing on the tree trunk, leading to a significant waste of pesticides. This also results in pesticide overuse, as excessive pesticides can accidentally kill beneficial insect predators such as bees and birds, increasing the risk of secondary outbreaks of pests and diseases. Furthermore, it pollutes the soil and water sources, inhibits soil microbial activity, affects the absorption function of plant roots, and disrupts the forest ecosystem.
[0004] Therefore, this utility model provides a spraying device for the prevention and control of forest pests and diseases to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a spraying device for the prevention and control of forest pests and diseases, which has the advantage of reducing the overuse of pesticides.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for the prevention and control of forest pests and diseases, comprising a working platform, a pesticide tank fixedly installed on the working platform, and a loading port opened on the top of the pesticide tank. A conveying box is provided at the bottom of the pesticide tank, and a water pump is fixedly installed inside the conveying box. The input end of the water pump is connected to the bottom of the pesticide tank through a pipe. A lifting mechanism is provided on the top of the working platform corresponding to one side of the pesticide tank. An adjustment mechanism for adjusting the spraying angle is provided on the top of the lifting mechanism. An arc-shaped rigid pipe is provided around the trunk at the end of the adjustment mechanism away from the lifting mechanism. A spraying port is fixedly provided on the inner side of the rigid pipe near the target tree trunk. A flexible pipe is connected to the bottom of the end of the rigid pipe near the adjustment mechanism. The end of the flexible pipe away from the rigid pipe passes through the conveying box and is fixedly connected to the output end of the water pump.
[0007] Preferably, the spray nozzles are provided in multiple quantities and are arranged in an array along the extension direction of the rigid pipe.
[0008] Preferably, the lifting mechanism includes a motor fixedly mounted on the working platform and a hydraulic telescopic rod fixedly connected to the output end of the motor.
[0009] Preferably, the adjusting mechanism includes a fixed sleeve fixedly connected to the top of the inner rod of the hydraulic telescopic rod, an electric telescopic rod A respectively disposed at both ends of the fixed sleeve, an electric telescopic rod B fixedly disposed on the inner rod of the electric telescopic rod A, and a protective plate fixedly connected to the end of the inner rod of the electric telescopic rod A away from the fixed sleeve. The fixed sleeve is rotatably fitted onto the outer rod of the electric telescopic rod A, and the two outer rods of the electric telescopic rod A are fixedly connected at their ends. The outer rod of the electric telescopic rod B penetrates the inner rod of the electric telescopic rod A in the radial direction.
[0010] Preferably, the adjustment mechanism further includes a servo motor fixedly connected to one end of the inner rod of the hydraulic telescopic rod near the fixed sleeve, a turntable A fixedly connected to the output end of the servo motor, and a turntable B fixedly connected to the outer rod corresponding to the electric telescopic rod A. The turntable A and the turntable B are driven by a belt.
[0011] Preferably, a connector is fixedly provided at the end of the inner rod of the electric telescopic rod B away from the fixed sleeve, and a bolt assembly is provided on the connector. The bolt assembly includes a bolt body and a nut, and the bolt body is fixedly connected to the rigid tube.
[0012] Preferably, there are two rigid tubes, each located at the end of the inner rod of the two electric telescopic rods B away from the fixed sleeve.
[0013] Preferably, the electric telescopic rod B is provided with a plurality of collars, which are movably connected to the flexible tube.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model uses an electric telescopic rod A. The electric telescopic rod A is adjusted according to the thickness of the target tree trunk, allowing the electric telescopic rod B on rod A to separate to a suitable distance. The extension of electric telescopic rod B causes the rigid tube at its end to extend forward, moving in an arc shape to surround the tree trunk. The position can then be further adjusted using electric telescopic rods A and B. A water pump draws pesticide from the pesticide tank and delivers it through a flexible tube into the rigid tube, then sprays it onto the tree trunk through the nozzles on the rigid tube. This allows for simultaneous spraying of pesticide from all directions around the tree trunk, eliminating the need to move the work platform around the trunk, saving time. Furthermore, this method ensures that the pesticide is sprayed directly onto the tree trunk, preventing pesticide overuse and environmental harm.
[0016] 2. This utility model, by setting up a hydraulic telescopic rod, can control the position of the adjustment mechanism while spraying the pesticide, and then control the longitudinal movement of the spray nozzle on the rigid pipe to spray the tree trunk at all heights. This spraying device is also applicable to trees that grow obliquely by operating the hydraulic telescopic rod and the electric telescopic rod A simultaneously.
[0017] 3. This utility model incorporates a servo motor, which drives turntable A to rotate, which in turn drives turntable B to rotate, thereby controlling the rotation of electric telescopic rod A and controlling the angle of electric telescopic rod B. By adjusting electric telescopic rod B to tilt upwards and downwards, the spraying height range of the spraying device can be increased. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1 to 4 As shown, this utility model provides a spraying device for the control of forest pests and diseases, including a working platform 1, a pesticide tank 2 fixedly installed on the working platform 1, and a loading port 21 opened on the top of the pesticide tank. A conveying box 3 is provided at the bottom of the pesticide tank 2, and a water pump 31 is fixedly installed inside the conveying box 3. The input end of the water pump 31 is connected to the bottom of the pesticide tank 2 through a pipe. A lifting mechanism 4 is provided on the top of the working platform 1 corresponding to one side of the pesticide tank 2. An adjustment mechanism 5 for adjusting the spraying angle is provided on the top of the lifting mechanism 4. The mechanism 5 has an arc-shaped rigid pipe 6 around the tree trunk at the end away from the lifting mechanism 4. A spray nozzle 61 is fixedly installed on the inner side of the rigid pipe 6 near the target tree trunk. A flexible pipe 7 is connected to the bottom of the end of the rigid pipe 6 near the adjusting mechanism 5. The end of the flexible pipe 7 away from the rigid pipe 6 passes through the delivery box 3 and is fixedly connected to the output end of the water pump 31. The water pump 31 draws the medicine from the medicine tank 2 and sends it into the rigid pipe 6 through the flexible pipe 7. Then, it sprays the medicine onto the tree trunk through the spray nozzle 61 on the rigid pipe 6. The rigid arc shape allows for spraying in all directions on the tree trunk.
[0027] Furthermore, refer to Figures 1 to 2 The spray nozzles 61 are provided in multiple arrays and distributed along the extension direction of the rigid tube 6, so that the sprayed medicine is as uniform as possible.
[0028] Furthermore, refer to Figure 1 , Figure 3The lifting mechanism 4 includes a motor 41 fixedly mounted on the working platform 1 and a hydraulic telescopic rod 42 fixedly connected to the output end of the motor 41. The hydraulic telescopic rod 42 can control the lifting and lowering of the adjusting mechanism 5, thereby controlling the rigid pipe 6 and the spray nozzle 61 to spray at different heights.
[0029] Among them, reference Figures 5 to 6 The adjusting mechanism 5 includes a fixed sleeve 51 fixedly connected to the top of the inner rod of the hydraulic telescopic rod 42, electric telescopic rods A52 respectively disposed at both ends of the fixed sleeve 51, electric telescopic rods B53 fixedly disposed on the inner rod of the electric telescopic rods A52, and a protective plate 54 fixedly connected to the end of the inner rod of the electric telescopic rods A52 away from the fixed sleeve 51. The fixed sleeve 51 is rotatably fitted onto the outer rod of the electric telescopic rods A52. The two outer rods of the electric telescopic rods A52 are fixedly connected at their ends. The outer rod of the electric telescopic rod B53 passes through the inner rod of the electric telescopic rods A52 in the radial direction. The electric telescopic rods A52 can control the electric telescopic rods B53, thereby controlling the distance between the other two rigid pipes 6 and the spray nozzle 61. The protective plate 54 protects the adjusting mechanism 5 from direct impacts from both sides, ensuring the safety of the device.
[0030] It should be noted that, referring to Figures 5 to 6 The adjustment mechanism 5 further includes a servo motor 55 fixedly connected to one end of the inner rod of the hydraulic telescopic rod 42 near the fixed sleeve 51, a turntable A56 fixedly connected to the output end of the servo motor 55, and a turntable B57 fixedly connected to the outer rod corresponding to the electric telescopic rod A52. The turntable A56 and the turntable B57 are driven by a belt. The servo motor 55 drives the turntable A56 to rotate, which in turn drives the turntable B57 to rotate, thereby controlling the rotation of the electric telescopic rod A52, and thus controlling the angle of the electric telescopic rod B53. By adjusting the electric telescopic rod B53 to tilt upwards and downwards, the spraying height range of the spraying device can be increased.
[0031] It is worth noting that, referring to Figures 1 to 2 The inner rod of the electric telescopic pole B53 is fixedly provided with a connector 8 at the end away from the fixed sleeve 51. The connector 8 is provided with a bolt assembly 81, which includes a bolt body 811 and a nut 812. The bolt body 811 is fixedly connected to the rigid tube 6. Rotating to loosen the nut 812 can adjust the angle of the bolt body 811 and the rigid tube 6 to adapt to tree trunks with different tilt angles. Tightening the nut 812 fixes the angle.
[0032] Furthermore, refer to Figures 1 to 2 There are two rigid tubes 6, each installed on the inner end of the two electric telescopic rods B53 away from the fixed sleeve 51, surrounding the tree trunk from both sides for all-round spraying.
[0033] Furthermore, refer to Figure 1 , Figure 3 The electric telescopic rod B53 is provided with several collars 531, which are movably connected to the flexible tube 7. The collars 531 can restrict the position of the flexible tube 7 and prevent the flexible tube 7 from getting tangled together and affecting the working effect.
[0034] Working principle and usage process of this utility model:
[0035] This is used to describe the instructions for use or operation of the technology. The working platform 1 of the spraying device can be moved by a trolley by installing rollers at the bottom, or it can be fixed on a vehicle for vehicle-mounted operation. When using the spraying device, first pour the mixed pesticide solution into the pesticide tank 2 through the loading port 21. Adjust the electric telescopic rod A52 according to the thickness of the target tree trunk, so that the electric telescopic rod B53 on the electric telescopic rod A52 is separated to a suitable distance. Control the extension of the electric telescopic rod B53, which will drive the rigid tube 6 at the end of the electric telescopic rod B53 to extend forward. The arc-shaped rigid tube 6 moves to a position around the tree trunk. At this time, the position can be further adjusted by the electric telescopic rods A52 and B53. The water pump 31 draws the pesticide solution from the pesticide tank 2 and sends it into the rigid tube 6 through the flexible tube 7. Then, it is sprayed onto the tree trunk through the spray nozzle 61 on the rigid tube 6, so that the pesticide can be sprayed in all directions on the tree trunk at the same time, without having to move the working platform 1 around the tree trunk. This method saves working time, and the sprayed pesticides are all targeted at the tree trunk, ensuring maximum coverage and preventing pesticide overuse and environmental harm. While spraying, the hydraulic telescopic rod 42 controls the position of the adjustment mechanism 5, which in turn controls the longitudinal movement of the spray nozzle 61 on the rigid pipe 6, allowing for comprehensive spraying of the tree trunk at various heights. The simultaneous operation of the hydraulic telescopic rod 42 and the electric telescopic rod A52 is also suitable for trees that grow at an angle. The servo motor 55 drives the turntable A56 to rotate, which in turn drives the turntable B57 to rotate, thereby controlling the rotation of the electric telescopic rod A52 and the angle of the electric telescopic rod B53. Adjusting the electric telescopic rod B53 to tilt upwards or downwards increases the spraying height range. The rotation of the motor 41 drives the hydraulic telescopic rod 42 to rotate, controlling the working direction of the adjustment mechanism 5, the rigid pipe 6, and the spray nozzle 61.
