[0016] Figure 2 This is a partial exploded view of a trunk injection machine with controllable injection volume according to this utility model. Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] See appendix Figure 1 and 2 , Figure 1 and 2 This is a schematic diagram of the main structure of a trunk spraying machine with controllable injection volume. The trunk spraying machine with controllable injection volume provided in this embodiment includes: a back box 1 and a drilling and injection assembly 2. The back box 1 houses a battery module 3, a liquid medicine tank 4, and an electric piston pump module 5. The battery module 3 provides power to the spraying machine. The liquid medicine tank 4 is used to hold the liquid medicine to be injected. The drilling and injection assembly 2 includes an injection assembly and a drilling assembly, the injection assembly having an injection tube 6; both the injection assembly and the drilling assembly can be based on existing technology.

[0019] The electric piston pump module 5 includes a pump body 7, a piston rod 8, and an electric push rod 9. The front end of the pump body 7 has an inlet 10 and an outlet 11. Both the inlet 10 and outlet 11 of the pump body 7 are equipped with one-way check valves to prevent backflow of the medicine. The medicine tank 4 is connected to the inlet 10 through a first fitting 12, and the outlet 11 is connected to the injection pipe 6 through a second fitting 13. The electric push rod 9 is an electric push rod 9 with a Hall sensor. The piston rod 8 slides inside the pump body 7, and the end of the piston rod 8 is connected to the electric push rod 9, so that the piston rod 8 can be driven by the electric push rod 9, thereby driving the piston to reciprocate within the pump body 7. The use of the electric push rod 9 with a Hall sensor can control the pushing distance, thereby controlling the injection volume per injection.

[0020] The battery module 3 is electrically connected to the injection assembly and the electric actuator 9. The handle of the drilling assembly houses a control module 14 for the electric actuator 9. This control module 14 is a touchscreen. Optionally, the touchscreen includes an injection switch button, a single injection volume increase button, and a single injection volume decrease button for the electric actuator 9. That is, the touchscreen can integrate a microcontroller. Upon receiving a signal from the injection switch button, the microcontroller controls the power supply to the electric actuator. Upon receiving a signal from the single injection volume increase button or the single injection volume decrease button, the microcontroller controls the single-push amount of the electric actuator (increasing or decreasing the single-push amount). This microcontroller can be a single-chip microcomputer. It should be noted that the above control logic is only the process of receiving and responding to electrical signals and requires no program modification.

[0021] During drilling operations, the drilling assembly is used to drill holes in the tree trunk, and then the injection assembly is used to inject the medicine. The touch screen on the handle is equipped with an injection switch button, a button to increase the single injection volume, and a button to decrease the single injection volume. It controls the switch control and stroke of the electric push rod 9 to achieve control of the injection volume.

[0022] The above describes the preferred embodiment of this utility model and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solution of this utility model without departing from the spirit and scope of this utility model shall fall within the protection scope of this utility model.
