Description

A precision spraying device for tree trunks used in rural roadside greening Technical Field

[0001] This invention belongs to the field of road greening technology, specifically relating to a device for precise application of pesticides to the trunks of trees used for greening rural roads. Background Technology

[0002] Trunk injection is an effective method for controlling pests on green trees. The process involves drilling holes at a 45° downward angle into the trunk, injecting pesticide into the holes. The holes are 0.5-0.8 cm in diameter and 5-10 cm deep, arranged in a spiral pattern along the trunk. After injection, the holes are sealed with mud pellets or adhesive tape to prevent pesticide evaporation. Using mud pellets mixed with a healing agent is the best method for sealing.

[0003] In existing devices, the amount of pesticide applied to tree trunks is generally determined by measuring the trunk. For rural roadside greening, there are many trees and a large workload, making it difficult to accurately measure the diameter of each tree trunk. Therefore, the amount of pesticide applied is generally estimated by visual inspection based on the tree diameter, which makes it difficult to be precise. Furthermore, for taller tree trunks, the efficiency of drilling holes, injecting pesticide, and sealing the trunks manually is too low. Summary of the Invention

[0004] The purpose of this invention is to provide a device for precise application of pesticides to the trunks of trees used for greening rural roads, in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A device for precise application of pesticides to the trunks of trees used for greening rural roads, comprising:

[0007] A tree climbing assembly for climbing tree trunks includes an L-shaped bar for clamping the tree trunk and a clamping bar slidably mounted on the surface of the L-shaped bar. A sliding sleeve is provided at the sliding point between the clamping bar and the L-shaped bar, and at least four clamping wheels driven by a motor are provided at the clamping point. The diameter of the tree trunk can be measured when clamping by using the sliding sleeve. The larger the diameter of the tree, the farther the distance between the clamping end of the clamping bar and the L-shaped bar. After clamping, the clamping wheels are rotated by the motor to perform the lifting and lowering tree climbing operation.

[0008] A drilling assembly for drilling includes a downwardly inclined slide at the end of an L-shaped rod, with an electric drill slidably mounted below the slide. The drilling assembly is mounted on a tree-climbing assembly and can rise to a suitable height with the tree-climbing assembly to drill downwards at an angle, reducing the difficulty of operation compared to manual operation.

[0009] An injection assembly for injecting chemicals into boreholes includes an injection cylinder and a chemical tank. The chemical tank is connected to the side wall of the injection cylinder near its tail end via a suction tube and a one-way valve. The piston of the injection cylinder is driven to extend and retract by a second cylinder, and the output end of the second cylinder is connected to the injection cylinder via a tension spring. A limit head is provided on the side of the piston of the injection cylinder, which is used to contact a sliding sleeve to limit the extension and retraction range of the piston according to the tree diameter. The injection cylinder is also provided with a thin tube and an injection tube. The injection tube has a telescopic head at its tail end, which extends forward under positive pressure and retracts under negative pressure. The telescopic head is provided with a pressure nozzle. The injection assembly is used to limit the extension and retraction range of the piston of the injection cylinder according to the clamping position of the clamping rod. When the second cylinder drives the piston to draw out the chemical, the injection cylinder can draw out the corresponding amount of chemical according to the tree diameter.

[0010] As a further optimization of the present invention, the clamping rod and the L-shaped rod are F-shaped, and the surface of the L-shaped rod is provided with a first cylinder for driving the clamping rod to slide. The clamping is performed by the first cylinder. Since the diameter of the tree trunk is different at different positions, the first cylinder continuously maintains the clamping force, which can make the tree climbing component firmly fixed on the tree trunk, so as to facilitate drilling and application of medicine.

[0011] As a further optimization of the present invention, the injection tube is located below the electric drill and aligned with the drilling position of the electric drill. Both the injection tube and the thin tube are fixed by an L-shaped fixing rod to bypass the travel path of the electric drill. In order to further realize automation, after the electric drill is completed, the injection tube can be directly inserted into the hole for injection by telescopic insertion. Therefore, the injection tube is placed below the electric drill.

[0012] As a further optimization of the present invention, the second cylinder is fixed parallel to the injection cylinder, and a connecting plate is provided at the output end of the second cylinder for connecting with the tension spring. Since the piston of the injection cylinder is limited by the sliding sleeve, the second cylinder can automatically adapt to the position of the piston when it drives the piston to draw and inject the drug through the tension spring.

[0013] As a further optimization of the present invention, the telescopic head is connected to the injection tube via a flexible folded bark. When the telescopic head is subjected to positive pressure, the folded bark folds outward, and when subjected to negative pressure, the folded bark folds inward. The pressure nozzle sprays when under pressure and tightens when under negative pressure. By specifically setting the structure of the injection tube, it can achieve the purpose of telescopic movement with a simple structure. This telescopic structure allows the injection tube to be inserted into the hole for injection, and retracts after injection, without affecting tree climbing.

[0014] As a further optimization of the present invention, the application device also includes a sealing component disposed at the end of the slide seat, which is used to seal the injection hole with mud pellets after the injection. Sealing with mud pellets is a conventional method of sealing, but it has always been done manually. In this application, the sealing component is disposed on the slide seat, which can be done at a higher part of the tree trunk, replacing manual climbing.

[0015] As a further optimization of the present invention, the sealing assembly includes a chute disposed above the slide block and a sickle-shaped baffle disposed at the tail end of the chute and hinged to the slide block. The baffle is used to block mud pellets, and the baffle contacts the tree trunk through a rubber head. When the baffle moves downward relative to the tree trunk, the baffle is lifted up. In this solution, the baffle blocks the mud pellets, and the mud pellets fall into the hole through the lifting and lowering operation of the tree climbing assembly, and has a smoothing function. The diameter of the mud pellets should be larger than the diameter of the medicine hole in the tree trunk.

[0016] The beneficial effects of this invention are as follows:

[0017] This invention improves the accuracy of pesticide application by setting up a tree-climbing component that climbs along the tree trunk, replacing manual labor, and adjusting the amount of pesticide injected in real time according to the trunk diameter. It also features an integrated automatic drilling, pesticide injection, and mud pellet sealing device, which can automatically perform high-altitude operations without the need for manual tree climbing, greatly improving the efficiency of trunk pesticide application.

Detailed Implementation

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] As shown in Figures 1-5, a device for precise application of pesticides to tree trunks used for greening trees along rural roads includes a tree climbing component 1, a drilling component 2, an injection component 3, and a sealing component 4.

[0028] The tree climbing assembly 1 is used to climb the tree trunk 5. It includes an L-shaped rod 11 for clamping the tree trunk 5 and a clamping rod 13 that is slidably disposed on the surface of the L-shaped rod 11. A sliding sleeve 12 is provided at the sliding part between the clamping rod 13 and the L-shaped rod 11. At least four clamping wheels 14 driven by a motor 15 are provided at the clamping part. The diameter of the tree trunk can be measured when clamping by the sliding sleeve 12. The larger the diameter of the tree, the farther the distance between the clamping end of the clamping rod 13 and the L-shaped rod 11 is. The position of the sliding sleeve 12 limits the subsequent amount of medicine injected. After clamping, the clamping wheels 13 are driven to rotate by the motor 15 to perform the tree climbing operation.

[0029] The drilling assembly 2 is used for drilling. It includes a slide block 21 that is inclined downward at the end of the L-shaped rod 11. An electric drill 22 is slidably arranged below the slide block 21. The drilling assembly 2 is set on the tree climbing assembly 1 and can follow the tree climbing assembly 1 to rise to a suitable height to drill downward at an angle. Compared with manual operation, it reduces the difficulty of operation.

[0030] The injection assembly 3 is used to inject chemicals into the borehole. It includes an injection cylinder 31 and a chemical tank 32. The chemical tank 32 is connected to the side wall of the injection cylinder 31 near its tail end via a suction tube 33 and a one-way valve. The piston of the injection cylinder 31 is driven to extend and retract by a second cylinder 34, and the output end of the second cylinder 34 is connected to the injection cylinder 31 via a tension spring 37. A limiting head 35 is provided on the side of the piston of the injection cylinder 31. The limiting head 35 contacts the sliding sleeve 12 to limit the extension and retraction range of the piston according to the tree diameter. The cylinder 31 is also equipped with a thin tube 38 and an injection tube 39. The injection tube 39 is equipped with a telescopic head 3901 at its tail end. It extends forward under positive pressure and retracts under negative pressure. The telescopic head 3901 is equipped with a pressure nozzle 3902. The injection assembly 3 is used to limit the piston of the injection cylinder 31 through the sliding sleeve 12 according to the clamping position of the clamping rod 13, thereby limiting the extension and retraction range of the piston of the injection cylinder 31. When the second cylinder 34 drives the piston to draw out the agent, the injection cylinder 31 can draw out the corresponding amount of agent according to the tree diameter.

[0031] The clamping rod 13 and the L-shaped rod 11 are F-shaped, and the surface of the L-shaped rod 11 is provided with a first cylinder 16 for driving the clamping rod 13 to slide. The clamping is performed by the first cylinder 16. Since the diameter of the tree trunk is different at different positions, the first cylinder 16 continuously maintains the clamping force, which can stabilize the tree climbing component 1 on the tree trunk, so as to facilitate drilling and applying medicine.

[0032] The injection tube 39 is located below the electric drill 22, aligned with the drilling position of the electric drill 22. Both the injection tube 39 and the thin tube 38 are fixed by the L-shaped fixing rod 310 to bypass the travel path of the electric drill 22. In order to further realize automation, after the electric drill 22 has completed drilling, the injection tube 39 can be directly inserted into the hole for injection by telescopic insertion. Therefore, the injection tube 39 is placed below the electric drill and bypassed by the fixing rod 310 to bypass the travel path of the electric drill 22.

[0033] The second cylinder 34 is fixed parallel to the syringe 31. The output end of the second cylinder 34 is provided with a connecting plate 36 for connecting with the tension spring 37. Since the piston of the syringe 31 is limited by the sliding sleeve 12, the second cylinder 34 can automatically adapt to the position of the piston when it drives the piston to draw and inject the drug.

[0034] The telescopic head 3901 is connected to the injection tube 39 via a flexible flap. When the telescopic head 3901 is under positive pressure, the flap folds outward; when under negative pressure, the flap folds inward. The pressure nozzle 3902 sprays when pressurized and tightens under negative pressure. By specifically designing the structure of the injection tube 39, it achieves telescopic functionality with a simple structure. This telescopic structure allows the injection tube 39 to be inserted into the hole for injection, and then retracts after injection, without affecting tree climbing. Specifically, as shown in Figure 1, the suction tube 33 is connected to the injection cylinder. The side wall of syringe 31 is connected to the end of syringe 31. When the piston of syringe 31 draws the drug, a negative pressure is generated in the thin tube 38. This negative pressure causes the residual drug in the thin tube 38 to flow back and the telescopic head 3901 to retract. When the drug is drawn again, the drug is drawn from the drug tank 32. When the drug is pushed, the one-way valve on the suction tube 33 blocks the push. The drug enters the telescopic head 3901 through the thin tube 38. The pressure nozzle 3901 is closed and requires pressure to spray out. Before spraying out, the telescopic head 3901 is pushed forward and enters the hole.

[0035] The application device also includes a sealing assembly 4 located at the end of the slide block 21, used to seal the injection hole with mud pellets 42 after injection. The sealing assembly 4 includes a groove 41 located above the slide block 21 and a sickle-shaped baffle 43 located at the tail end of the groove 41 and hinged to the slide block 21. The baffle 43 is used to block the mud pellets 42, and the baffle 43 contacts the tree trunk 5 through a rubber head 44. When the baffle 43 moves downward relative to the tree trunk 5, the baffle 43 is lifted up. Previously, this was done manually. The sealing component 4 can be installed on the slide 21 at a higher part of the tree trunk 5, replacing manual climbing. Specifically, as shown in Figure 5, when climbing the tree, the baffle 43 is pressed to block the mud ball. After drilling and injecting the medicine, the tree climbing component 1 descends, the baffle 43 is lifted upward, and the mud ball 42 slides down and enters the medicine hole under the guidance of the slide 41. The diameter of the mud ball 42 should be larger than the medicine hole and half-stuck at the opening of the medicine hole. Then the tree climbing component 1 moves up slightly and the bottom end of the slide 41 moves upward to smooth the mud ball.

[0036] The specific implementation method is as follows: After clamping the tree climbing component 1 to the tree trunk 5, add the mud pellet 42, and then raise the tree climbing component 1. After reaching the appropriate position, drill holes, extract medicine, inject, and seal the opening in the above manner. After completion, lower down. Since the medicine holes need to be arranged spirally along the tree trunk to rise, the medicine application port is lowered after one application. After adjusting the angle, climb up again.

[0037] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
