Description

Technical Field

[0001] The utility model relates to the field of garden protection equipment, in particular to a liquid medicine supply pipeline mechanism for a high-pressure minimally invasive forest injection machine. Background Art

[0002] Garden plants are often threatened by pests and diseases during their growth, and chemical control is the main means. Traditional injection of pesticides is effective against surface pests and diseases, but has poor effects on borers and piercing and sucking pests. For this reason, tree trunk drilling and injection came into being, and pesticides were directly injected into the plant, saving liquid medicine, improving the control effect, and reducing environmental pollution. Chinese patent number CN202320230862.8 provides a high-pressure tree minimally invasive spraying gun, including a drilling assembly and a drug source assembly, the drilling assembly includes an electric drill, a rotary joint and a drill bit, the rotary joint includes a rotary joint housing and a rotating mandrel, the rotary joint housing is fixedly connected to the hand electric drill housing through a bracket, one end of the rotating mandrel is connected to the drill chuck of the electric drill, and the other end of the rotating mandrel is connected to the drill bit, the rotating mandrel housing is provided with a liquid inlet, the drill bit is provided with a liquid outlet, and the rotating mandrel and the drill bit are provided with a liquid channel connecting the liquid inlet and the liquid outlet, and the drug source assembly includes a medicine pot, and the liquid in the medicine pot is connected to the liquid inlet through a liquid pressurizing mechanism. The medicine liquid pressurizing mechanism includes an electric push rod and a syringe. The syringe includes a cylinder body and a piston. The piston is arranged on the telescopic end of the electric push rod. The cylinder body is respectively provided with a medicine suction nozzle and a medicine injection nozzle. The medicine suction nozzle is connected to the medicine pot through a pipeline with a one-way valve, and the medicine injection nozzle is connected to the liquid inlet on the rotary joint shell through a pipeline with a one-way valve.

[0003] A one-way valve is a valve that only allows fluid to flow in one direction. Its working principle is based on the pressure and flow direction of the fluid. When the flow direction of the medium is consistent with the direction of the valve design, the valve disc will open and the medium can flow; conversely, when the flow direction of the medium is opposite to the direction of the valve design, the valve disc will close to prevent the reverse flow of the medium.

[0004] Once the one-way valve is corroded by the liquid medicine and becomes ineffective, it can no longer effectively prevent the backflow of the liquid medicine. During injection, the booster equipment will inject the liquid medicine at high pressure in the entire pipeline, and the liquid medicine will flow back to the pot at high pressure, which can easily cause the liquid medicine in the pot to be injected out, damaging the equipment, corroding, and endangering the operator. In addition, since the vulnerable parts such as the piston, cylinder and pipeline are exposed to the outside, they are easily affected by the external environment, resulting in corrosion, wear or contamination of the parts, affecting their normal operation and life. In order to prevent the above situation, the above parts are usually sealed in the box. Once the one-way valve is broken, it is not only necessary to unpack and replace it, but also require special after-sales maintenance, which will seriously extend the construction period. Summary of the invention

[0005] In order to solve the deficiencies in the prior art, the present invention aims to provide a liquid medicine supply pipeline mechanism for a high-pressure minimally invasive forestry injection machine.

[0006] In order to achieve the above functions, the present invention will adopt the following technical solutions:

[0007] A liquid medicine supply pipeline mechanism for a high-pressure minimally invasive forest injection machine includes a medicine injection drilling mechanism, a liquid medicine supply mechanism and a boosting mechanism. The liquid medicine supply mechanism includes a medicine box, and the liquid medicine in the medicine box enters the medicine injection drilling mechanism through the boosting mechanism. The boosting mechanism is characterized in that the boosting mechanism is a push cylinder, a first liquid guide tube is provided between the medicine box and the liquid inlet of the push cylinder, the medicine box is connected to the liquid inlet of the push cylinder through the first liquid guide tube, a second liquid guide tube is provided between the liquid outlet of the push cylinder and the medicine injection drilling mechanism, the second liquid guide tube is a high-pressure liquid guide tube, a first solenoid valve is provided on the first liquid guide tube, and a second solenoid valve is provided on the second liquid guide tube. The solenoid valve usually includes a valve body and a movable valve core inside. When the valve core is closed, it is attracted by the electromagnetic coil and sucked onto the valve seat to form a tight sealing structure, which effectively prevents the drug liquid from entering the valve. This structural design prevents the liquid medicine from contacting the metal parts inside the valve, thereby reducing the possibility of corrosion.

[0008] A one-way valve usually consists of a valve body and a valve. When liquid pressure acts on the valve, the valve opens and the liquid flows; otherwise, the valve closes. However, even in the closed state, since the contact between the valve and the valve seat of the one-way valve is usually loose, the liquid can still penetrate into the valve and cause corrosion of the metal parts.

[0009] The solenoid valve achieves precise control of the valve by controlling the on and off of the electromagnetic coil. The flow and pressure of the liquid medicine can be precisely adjusted as needed, thereby reducing the time the liquid medicine stays in the valve, which helps reduce the corrosion of the liquid medicine to metal parts.

[0010] The utility model is provided with a medicine dosage adjustment button, which is used for controlling the cylinder retraction action of the push cylinder by pressing the medicine dosage adjustment button according to the tree species and the disease condition of the tree, thereby adjusting the delivery amount of the medicine liquid.

[0012] The utility model is provided with a main power supply to provide power support for the entire circuit of the high-voltage minimally invasive forest injection machine.

[0013] The main power supply of the utility model is located in the injection control box and is detachably installed for easy charging.

[0014] The utility model provides a main power switch and a push cylinder medicine quantity adjustment button on the outside of the injection control box, so as to control the main power supply and medicine quantity adjustment.

[0015] The first liquid guide tube of the utility model is provided with a non-contact liquid level sensor so as to understand the amount of liquid medicine in the medicine box.

[0016] The utility model is provided with a control system, which includes a main power supply, the main power supply and a medicine dosage adjustment button are connected to a controller through an input line, and the controller is connected to an indicator light, a buzzer alarm, a push cylinder, a first solenoid valve and a second solenoid valve through an output line.

[0017] The utility model adopts a solenoid valve to control the flow of liquid medicine. When the valve core is closed, it is attracted by the electromagnetic coil and sucked onto the valve seat, forming a tight sealing structure, effectively preventing the liquid medicine from entering the valve, effectively preventing the liquid medicine from corroding the solenoid valve, and extending the life of the equipment. By setting a medicine amount adjustment button, the amount of liquid medicine delivered can be adjusted according to the tree type and the disease condition by adjusting the cylinder withdrawal action of the push cylinder, thereby realizing flexible control of the amount of medicine. By pushing the cylinder through the booster mechanism, the liquid medicine can be accurately delivered from the medicine box to the injection drilling mechanism, thereby ensuring the accuracy of the liquid medicine supply. The medicine box, controller, push cylinder, solenoid valve, etc. are placed in the injection control box, integrating the equipment, facilitating management and maintenance. The main power supply is located in the injection control box and can be detachably installed, which is convenient for charging and replacement, thereby ensuring continuous power supply of the equipment.
