Description

Technical Field

[0001] This utility model relates to the field of forest tree control technology, and in particular to a trunk drilling and injection machine and a trunk injection device. Background Technology

[0002] Trunk drilling and injection technology is a pest control method that involves directly injecting pesticide solution into the xylem of trees. A specialized drilling and injection machine is used to drill deep holes in the trunk, and then a hollow drill bit is used to evenly release the pesticide solution into the vascular tissue, achieving highly efficient and low-toxicity control of pests and diseases. This technology has advantages such as low pesticide dosage, long-lasting effect, and minimal environmental pollution, and has been widely used in the protection of urban street trees, economic forests, and ancient trees.

[0003] For example, Chinese patent CN222621688U discloses a trunk drilling and injection device for controlling forest pests and diseases. The device consists of an axially movable inner rod inside the drill bit, with an arc-shaped sealing plate on its outer circumference. During drilling, tightening the screw causes the inner rod to overcome the spring force of a first spring, and the sealing plate completely seals the injection hole, preventing sawdust from entering the drill bit. Once the predetermined hole depth is reached, loosening the screw in the opposite direction causes the inner rod to return to its original position under the action of the first spring, and the sealing plate leaves the injection hole, allowing the pesticide to be injected into the tree through a through-hole on the side wall of the drill bit. This structure is considered to effectively solve the problem of sawdust clogging and improve the smoothness of pesticide injection.

[0004] However, in actual use, the device requires manual and repeated rotation of the screw to lock or release the inner rod each time it is used. This is not only cumbersome and time-consuming, but also difficult to do with one hand in high-altitude or narrow environments, which reduces work efficiency. At the same time, frequent forward and reverse rotation can cause thread wear, leading to positioning failure. The sealing plate cannot reliably close or open the injection hole, which in turn causes leakage of the medicine or blockage of wood chips, affecting the prevention and control effect and increasing maintenance costs. Utility Model Content

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0025] This embodiment mainly describes the trunk drilling and injection machine, as follows:

[0026] like Figures 1 to 4 As shown, the tree trunk drilling and injection machine includes a drilling machine 2 and an injection device 1. The drilling machine 2 is used to drill holes in the tree trunk, and the injection device 1 is used to inject the medicine into the holes. The injection device 1 is equipped with a connecting part 13 for connecting to the drilling machine 2. The connecting part 13 is detachably fixed to the drilling machine 2. The drill bit axis of the drilling machine 2 is along the X-axis, and the injection port axis of the injection device 1 is along the Y-axis. The drilling direction and the injection direction need to be rotated 90°. The specific usage method is as follows: First, make the drilling machine 2 perpendicular to the tree trunk to complete the drilling; then rotate the whole machine 90°, and the injection device 1 will be directly in front of the hole to inject medicine. The whole process does not require disassembling and assembling the drill bit, nor does it require repeated tightening and loosening of the screw. It realizes one-click switching between drilling and injection modes, which significantly improves the working efficiency in high-altitude or narrow environments, and completely avoids the thread wear and sealing failure problems caused by frequent screw tightening in existing technologies.

[0027] Drilling machine 2 is an impact drill or electric drill tool. During manufacturing, the impact drill or electric drill has threaded holes pre-drilled on both sides of the housing for mounting handles. For example... Figure 1 and Figure 3 As shown, the connecting part 13 spans the U-shaped frame 131 of the impact drill or electric drill. The two arms of the U-shaped frame 131 have symmetrically arranged connecting holes 132. The U-shaped frame 131 is securely locked to the neck of the impact drill or electric drill by bolts passing through the connecting holes 132 and screwing into the threaded holes. This structure utilizes the existing interface of the impact drill or electric drill without additional processing, and ensures that the injector 1 is rigidly and vertically positioned with the impact drill or electric drill. This ensures the machine remains stable and does not shake when rotating and switching positions, guaranteeing that the orifice and the injector head 12 remain coaxial and preventing leakage of the injector solution.

[0028] Specifically, as another quick assembly and disassembly solution, the connecting part 13 can also be a clamp (not shown in the figure) covering the housing of the drilling machine 2 (impact drill or electric drill). The clamp has fastening bolts that adjust the opening spacing. By adjusting the fastening bolts to tighten the opening spacing, the tightness can be completed in a few seconds. It is suitable for universal installation of drilling machines 2 with different diameters. The clamp is welded to the injector 1 as a whole, so that the injector 1 always maintains a 90° angle with the axis of the impact drill. The positioning is also accurate when rotating and switching positions. Moreover, no tools are required for assembly and disassembly, making it more adaptable to the field.

[0029] Specifically, the injector 1 consists of a piston pump 11 and a slender injection head 12. The piston pump 11 has an inlet 111 and an outlet 112. The inlet 111 is connected to a backpack or hand-held medicine tank via a flexible hose. A one-way valve 113 is installed at the inlet 111 to allow the medicine to flow only from the medicine tank into the pump chamber 116, preventing backflow. The outlet 112 is connected to the injection head 12, and a second one-way valve 114 is installed between the outlet 112 and the injection head 12. The second one-way valve 114 ensures that the medicine can only flow from the pump chamber 116 of the piston pump 11 to the injection head 12 and will not backflow. One reciprocating motion of the piston 115 completes one liquid intake-discharge cycle, intermittently and quantitatively injecting the medicine from the medicine tank into the hole, avoiding over-injection that could cause damage to the tree and reducing waste of medicine.

[0030] like Figure 3 As shown, to facilitate maintenance of the injector 1 and prevent the drug housing from clogging the inside of the injector 1, the two ends of the one-way valve 113 are threadedly connected to the connection of the drug outlet 112 and the injection head 12, respectively. When cleaning is required, the one-way valve 113 can be rotated to disassemble the one-way valve 113, and the inside of the injector 1 can be further cleaned.

[0031] Specifically, for use in power-free outdoor environments, the piston pump 11 is equipped with a purely mechanical hand-driven structure 14 on its outer side. For example... Figure 1 and Figure 2 As shown, the hand-driven structure 14 includes a first handle 141 and a second handle 142. The first handle 141 is hinged to the tail of the piston pump 11, and the second handle 142 is fixed to the side wall of the pump body. The first handle 141 and the second handle 142 form a "clamp" grip. The front end of the first handle 141 is provided with a stop part 143, which abuts against the outer end of the piston 115. When the operator holds both handles with one hand and clamps them inward, the stop part 143 pushes the piston 115 to compress the pump chamber 116, and the liquid medicine is ejected from the injection head 12 through the second check valve 114. After the force is released from the first handle 141 and the second handle 142, the spring 117 in the piston pump 11 resets the piston 115, and the pump chamber 116 generates negative pressure to open the first check valve 113. The liquid medicine in the medicine tank is drawn into the inner cavity of the piston pump 11 through the first check valve 113. The entire process of drug suction and injection can be completed with a single press. This manual drive system requires no external power, and the machine is lightweight, making it suitable for complex terrains such as mountainous areas and understory forests.

[0032] Specifically, in the assembled state, the hand-operated handle 141 (i.e., the injector handle 141) is located on the left or right side of the drilling machine (impact drill or electric drill) and extends outward, its height being roughly level with the original main handle of the impact drill. When drilling, the operator holds the main handle of the impact drill with one hand and naturally holds handle 141 with the other hand; at this time, handle 141 acts as an auxiliary grip, forming a symmetrical "double fulcrum" structure with the main handle, which can effectively counteract the clockwise torque generated when the impact drill rotates, prevent the drill bit from deviating, and ensure the verticality of the hole. Example 2

[0033] The difference between this embodiment and Embodiment 1 lies only in providing an alternative injector structure to replace the injector structure in the above scheme. Specifically, the injector 1 includes an electric water pump and an injection head 12. The electric water pump is connected to the injection head and is battery-powered. The electric water pump is connected to the medicine tank via a hose. This scheme is electrically driven and suitable for occasions requiring continuous, large-volume injection, greatly reducing labor intensity while improving work efficiency. Example 3

[0034] This embodiment mainly describes the trunk injection device, as follows:

[0035] like Figures 1 to 4 As shown, the injection device 1 includes a hand-driven structure 14, a piston pump 11, an injection head 12, and a connecting part 13. The piston pump 11 has an inlet 111 and an outlet 112. The inlet 111 is connected to a backpack or hand-held medicine container via a hose. A one-way valve 113 is provided at the inlet 111 to allow only the liquid medicine to flow into the pump chamber 116. The outlet 112 is connected to the injection head 12, and a second one-way valve 114 is provided at the outlet 112. The second one-way valve 114 ensures... The liquid medicine can only flow from the pump chamber 116 of the piston pump 11 to the injection head 12. The connecting part 13 is located below the piston pump 11 or the injection head 12. The piston pump 11 is provided with a hand drive structure 14 on the outside. The hand drive structure 14 includes a U-shaped frame 131. The two arms of the U-shaped frame 131 are symmetrically provided with connecting holes 132. The injection device 1 is firmly locked to the neck of the impact drill or electric drill by passing a bolt through the connecting hole 132 of the U-shaped frame 131 and screwing it into the threaded hole.

[0036] Specifically, the hand-driven structure 14 includes a first handle 141 hinged to the tail of the piston pump 11 and a second handle 142 fixed to the side wall of the piston pump 11. The front end of the first handle 141 has an abutment part 143 that abuts against the outer end of the piston. When the first handle 141 and the second handle 142 are clamped inward, the abutment part 143 pushes the piston 115 to compress the pump chamber 116 to inject the drug. After the force is released from the first handle 141 and the second handle 142, the piston 115 returns to its original position and draws in the drug under the action of the spring 117 inside the piston pump 11. The hand-driven structure 14 ensures that the injector 1 can continue to work when there is no power.
