Description

Technical Field

[0001] This utility model relates to the field of tree root injection device technology, specifically a precision injection device for the roots of forestry trees. Background Technology

[0002] During the growth process, trees need to be injected with pesticides, growth regulators, trace elements, antibiotics, nutrient solutions, etc. Infusing trees with liquids to prevent and treat diseases and pests has become an important means of plant protection for garden seedlings. This method can ensure the growth and development of trees and prevent them from encountering some harmful organisms during their growth. At present, tree injection mainly adopts several methods such as hole injection, tube insertion or bottle insertion, and pressure injection. The hole injection method can inject the drug into the tree roots, and through the growth of the tree, the drug solution is evenly delivered to the tree to kill pests.

[0003] For example, patent application number 202111370282.0 discloses a tree root injector for forestry engineering. This invention relates to a tree root injector, and more particularly to a tree root injector for forestry engineering, including a rectangular slide rail frame, a handle, a sliding support block, a hollow drill rod, and a motor. The handle is fixedly connected to the rectangular slide rail frame, the sliding support block is slidably connected to the rectangular slide rail frame, the hollow drill rod is rotatably connected to the sliding support block, and the motor is fixedly installed on the top surface of the sliding support block. Through the coordinated rotation and downward movement of the hollow drill rod, the hollow drill rod drills into the tree root, facilitating the injection of medicine. At the same time, the rotation of the hollow drill rod helps to evenly inject the medicine into the tree root, making it easier for the tree root to fully absorb the medicine. However, when using this tree root injector for forestry engineering, if the needle is inserted into the pre-drilled hole, if deviation or jamming occurs, the injection needle may bend under the force of continuous force, causing damage to the needle.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a precision injection device for the roots of forest trees. Utility Model Content

[0005] The purpose of this invention is to provide a precision pesticide injector for the roots of forest trees to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision injection device for the roots of forest trees, comprising an injection device body, a dosing tank mounted on the upper surface of the injection device body, a pressure boosting connector provided on the rear surface of the injection device body, a telescopic sliding sleeve provided on the front surface of the injection device body, an injection needle provided on the front surface of the telescopic sliding sleeve, and the injection needle connected to the injection device body via a flexible tube, a threaded groove provided on the outer surface of the telescopic sliding sleeve, and a pressure relief spring sleeved on the outer surface of the telescopic sliding sleeve.

[0007] Preferably, a spiral sleeve is spirally mounted on the outer surface of the threaded groove, and the spiral sleeve and the pressure relief spring are configured as a friction connection.

[0008] Preferably, damping pads are provided on both sides of the injector body, and rotating sleeves are rotatably mounted on the surface of the damping pads.

[0009] Preferably, the outer surface of the rotating sleeve is provided with a sleeve, and the inner surface of the sleeve is equipped with a compression spring.

[0010] Preferably, a sliding support rod is slidably mounted on the inner wall surface of the sleeve, and a positioning head is provided at the end of the sliding support rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the arrangement of the injection device body, the dosing tank, the pressure-increasing connector, the telescopic sliding sleeve, the injection needle tube, the threaded groove, the spiral pressure sleeve, and the pressure relief spring, can protect the injection needle tube by compressing it when resistance or jamming occurs when the injection device body drives the injection needle tube to be inserted into the root of the tree trunk. This prevents the injection needle tube from bending and being damaged. 2. This utility model, through the setting of damping pads, rotating sleeves, sleeves, compression springs, sliding support rods and positioning heads, can pre-position the injector body when injecting into the roots of the tree trunk, thereby ensuring the stability of the injector body during injection and avoiding damage to the injection needle tube caused by shaking during injection.

[0014] 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.

[0015] like Figures 1-2 As shown, a precision injection device for the roots of forest trees includes an injection device body 1, a dosing tank 2 installed on the upper surface of the injection device body 1, a pressure-boosting connector 3 provided on the rear surface of the injection device body 1, a telescopic sliding sleeve 4 provided on the front surface of the injection device body 1, and an injection needle 5 provided on the front surface of the telescopic sliding sleeve 4. The injection needle 5 is connected to the injection device body 1 via a flexible tube. In this technical solution, the injection needle 5 can be moved by telescopic movement through the telescopic sliding sleeve 4.

[0016] Furthermore, the outer surface of the telescopic sliding sleeve 4 is provided with a threaded groove 6, and a pressure relief spring 8 is fitted on the outer surface of the telescopic sliding sleeve 4. With this technical solution, by setting the pressure relief spring 8, if resistance or jamming occurs when the injector body 1 drives the injection needle tube 5 to be inserted into the root of the tree trunk, the pressure relief spring 8 will compress and drive the injection needle tube 5 to contract, thereby preventing the injection needle tube 5 from bending and being damaged, and thus protecting the injection needle tube 5.

[0017] Furthermore, a spiral sleeve 7 is spirally installed on the outer surface of the threaded groove 6, and the spiral sleeve 7 and the pressure relief spring 8 are configured to be in friction connection. With this technical solution, the spiral sleeve 7 can be driven to press the pressure relief spring 8 by spiral movement, thereby adjusting the pressure relief threshold of the pressure relief spring 8.

[0018] like Figure 3 As shown, damping pads 9 are provided on both sides of the injector body 1, and rotating sleeves 10 are rotatably mounted on the surface of the damping pads 9. With this technical solution, the positioning head 14 can be rotated by damping friction through the setting of the rotating sleeves 10.

[0019] Furthermore, a sleeve 11 is provided on the outer surface of the rotating sleeve 10, and a compression spring 12 is installed on the inner surface of the sleeve 11. With this technical solution, the sliding support rod 13 can be reset by the setting of the compression spring 12.

[0020] Furthermore, a sliding support rod 13 is slidably installed on the inner wall surface of the sleeve 11, and a positioning head 14 is provided at the end of the sliding support rod 13. With this technical solution, the positioning head 14 can be positioned in advance when the injector body 1 is used to inject into the root of the tree trunk, so as to ensure the stability of the injector body 1 during injection and avoid damage to the injection needle tube 5 caused by shaking during injection.

[0021] Operating Principle: When using this precision root sprayer for forestry trees, first, connect the pressurized air hose to the pressurizing connector 3, then add pesticide to the pesticide tank 2 of the sprayer body 1. After adding the pesticide, align the spray needle 5 with the drilled hole and push the sprayer body 1. The positioning heads 14 on both sides of the sprayer body 1 will first contact the ground to position the hole. After the spray needle 5 passes through the hole, the sliding support rod 13 will slide into the sleeve 11 to prevent the spray needle 5 from penetrating further, until the spray needle 5 reaches the appropriate position for pesticide injection. If jamming occurs during the penetration of the spray needle 5, and the downward force of the sprayer body 1 exceeds the protection value of the pressure relief spring 8, the pressure relief spring 8 will compress to retract the spray needle 5 and protect it. This is the working principle of this precision root sprayer for forestry trees.
