Description

Technical Field

[0001] The utility model relates to the technical field of termite prevention and control, in particular to an underground termite prevention and control medicine drencher. Background Art

[0002] Termites are a worldwide pest of significant economic importance, damaging buildings, water conservancy projects, agricultural and forestry crops, buried pipelines, and other sectors of the national economy. There are two primary strategies for termite control: prevention and eradication. Termite prevention involves taking various measures before termites infect the protected area, preventing them from invading and causing damage.

[0003] The soil chemical barrier method is one of the important technologies currently used in the prevention of termites in residential buildings. It mainly uses professional preventive agents to spray on the foundation of the house or the surrounding soil to achieve the purpose of termite prevention. For residential buildings that cannot be constructed due to missed time or need supplementary prevention construction, the method of injecting liquid medicine into the soil around the building can be used for preventive treatment.

[0004] Existing termite control spraying equipment is primarily suitable for above-ground applications. There are few specialized nozzles on the market for soil injection. During underground injection, soil can easily clog the injection port, hindering proper injection. Furthermore, the single injection volume is limited by the capacity of the injection gun. After the gun is depleted, it must be reloaded before the next injection can begin, resulting in low efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing underground termite control medicine injector is easily blocked by soil, affecting normal injection, and cannot continuously inject medicine, resulting in low efficiency.

[0006] In order to solve the above problems, the technical solution of the present invention is: an underground medicine injector for termite control, comprising a medicine storage cartridge, a medicine guide tube connected to the bottom of the medicine storage cartridge, a handle fixed to the side wall, a medicine tonic component provided on the top of the medicine storage cartridge, a medicine discharge component symmetrically provided on the bottom, a piston movably provided inside, a round rod fixed to one side of the piston passing through the end face of the medicine storage cartridge, two limiting rings symmetrically fixed to the inner side of the medicine tonic component inside the medicine storage cartridge, a medicine outlet pipe fixed to the bottom of the medicine guide tube, the diameter of the medicine outlet pipe is smaller than that of the medicine guide tube, and a plurality of medicine outlet ports are provided on the bottom surface of the medicine outlet pipe, and a blocking cover is movably provided on the outer sleeve of the medicine outlet pipe.

[0007] Furthermore, the medicine supplement component includes a medicine inlet pipe, the bottom of which is connected to a horizontal pipe 1, and both ends of the horizontal pipe 1 are installed with a one-way valve 1, and are connected to the upper parts of the two ends of the medicine storage cartridge.

[0008] Furthermore, the drug discharge assembly includes a drug discharge pipe, the top of which is connected to a second transverse pipe, both ends of which are equipped with a second one-way valve, and are connected to the lower parts of both ends of the drug storage cylinder.

[0009] Furthermore, a connecting pipe sleeved on the outside of the drug discharge pipe is fixedly connected to the top of the drug guiding pipe, and meshing threads are provided on the outer wall of the drug discharge pipe and the inner wall of the connecting pipe.

[0010] Furthermore, a handle is fixedly connected to the end of the round rod, and a sealing ring sleeved on the outside of the round rod is fixedly connected to the outside of the drug storage cartridge.

[0011] Furthermore, the bottom of the blocking cover is conical, and a groove adapted to the medicine outlet tube is provided on the top surface thereof.

[0012] Furthermore, a plurality of cavities connected to the grooves are provided inside the blocking cover, and the cross-section of the cavities is convex-shaped. A plurality of connecting rods extending into the cavities are fixedly connected to the bottom of the medicine outlet tube, and a limit plate is fixedly connected to the bottom of the connecting rod. A spring is provided above the limit plate and is sleeved on the outside of the connecting rod.

[0013] The advantages of the present invention compared with the existing technology are: the present invention moves the piston back and forth by the handle, and the medicine storage cartridge can continuously feed and discharge medicine, thereby achieving uninterrupted and continuous drug administration, thereby improving the drug filling efficiency; when the medicine is discharged from the medicine outlet hole at the bottom of the medicine outlet pipe, it will generate a downward thrust on the blocking cover, and separate it from the medicine outlet pipe, completing the drug filling. After the drug filling is completed, the blocking cover is again put on the outside of the medicine outlet pipe, thereby effectively preventing soil from clogging the medicine outlet hole.

[0020] like Figures 1 to 2 As shown, an underground drug drencher for termite control includes a drug storage cartridge 1, a drug guide tube 2 is connected to the bottom of the drug storage cartridge 1, a handle 3 is fixed to the side wall, a drug supplement component is provided on the top of the drug storage cartridge 1, a drug discharge component is symmetrically provided on the bottom, a piston 4 is movably provided inside, a round rod 5 that passes through the end face of the drug storage cartridge 1 is fixed to one side of the piston 4, two limiting rings 6 are symmetrically fixed to the inner side of the drug supplement component inside the drug storage cartridge 1, a handle 14 is fixed to the end of the round rod 5, and a sealing ring 15 that is sleeved on the outside of the round rod 5 is fixed to the outside of the drug storage cartridge 1.

[0021] The medicine replenishing component includes a medicine inlet pipe 9, the bottom of which is connected to a horizontal pipe 10, and the left and right ends of the horizontal pipe 10 are respectively installed with a one-way valve 1A and a one-way valve 1B, and are connected to the upper parts of the two ends of the medicine storage cartridge 1. The medicine discharging component includes a medicine discharging pipe 11, the top of the medicine discharging pipe 11 is connected to a horizontal pipe 2 12, and the left and right ends of the horizontal pipe 2 12 are respectively installed with a one-way valve 2A and a one-way valve 2B, and are connected to the lower parts of the two ends of the medicine storage cartridge 1.

[0022] Connect the drug inlet pipe 9 to the external drug delivery pipeline. When the piston 4 is pulled to the right by the handle 14, the one-way valve 1 A and the one-way valve 2 B are opened. When the piston 4 is pushed to the left by the handle 14, the one-way valve 1 B and the one-way valve 2 A are opened, thereby enabling continuous drug delivery. The one-way valve 1 and the one-way valve 2 are ball-type one-way pressure valves.

[0023] like Figure 1 、 Figure 3 and Figure 4 As shown, the bottom of the drug guide tube 2 is fixedly connected to a drug outlet tube 7, the diameter of the drug outlet tube 7 is smaller than the diameter of the drug guide tube 2, and a plurality of drug outlet ports are provided on the bottom surface of the drug outlet tube 7, and a baffle 8 is movably sleeved on the outer side of the drug outlet tube 7.
