[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0027] Please refer to Figure 1-9 , a device for controlling termites in embankments with automatic dosing, comprising a dosing cylinder 2, a sealing piston disc 31 provided in the dosing cylinder 2, a lifting cylinder 3 extending upwardly provided on the surface of the sealing piston disc 31, a connected liquid storage cylinder 5 provided on the outside of the dosing cylinder 2, the sealing piston disc 31 and the lifting cylinder 3 moving upward to suck the liquid in the liquid storage cylinder 5 into the dosing cylinder 2, a rotating mechanism provided under the sealing piston disc 31, the liquid entering the dosing cylinder 2 while driving the rotating mechanism to operate, a discharge hole 241 provided on the bottom surface of the dosing cylinder 2, the discharge hole 241 being connected to the discharge pipe 24 A sealing valve is provided on the medicine discharge pipe 24. Under normal circumstances, the liquid in the liquid storage cylinder 5 is blocked and cannot enter the dosing cylinder 2. When in use, the medicine for controlling termites is poured into one of the liquid storage cylinders 5, and water is poured into the other liquid storage cylinder. When the sealing piston disc 31 and the lifting cylinder 3 move upward, the bottom of the dosing cylinder 2 is in a negative pressure state. At this time, the medicine liquid and water enter the dosing cylinder 2 at the same time. Since the rotating mechanism is linked with the sealing piston disc 31, when the sealing piston disc 31 moves upward, the rotating mechanism is operated to stir and dilute the entering medicine liquid and water, and finally the medicine liquid is discharged from the medicine discharge pipe 24 to control the dam termites.

[0028] In the solution of the present invention, a support plate 21 is provided on the outer circumference of the dosing cylinder 2, and a through hole 22 is provided on the surface of the support plate 21. An L-shaped connecting tube 23 is provided below the support plate 21, and one end of the L-shaped connecting tube 23 is connected to the liquid storage cylinder 5 through the through hole 22, and the other end is connected to the dosing cylinder 2, wherein the connecting position of the L-shaped connecting tube 23 and the dosing cylinder 2 is always below the sealing piston disk 31, and a sealing mechanism for blocking the flow of the liquid medicine is provided in the L-shaped connecting tube 23. Under normal circumstances, the port of the L-shaped connecting tube 23 is blocked by the sealing mechanism, thereby preventing the liquid medicine and water from entering the dosing cylinder 2.

[0029] When in use, the blocking mechanism blocks the L-shaped connecting pipe 23, and the drug discharge pipe 24 is sealed by the sealing valve. At this time, a closed space is formed under the sealing piston disc 31. When the sealing piston disc 31 moves upward, the internal negative pressure is generated. At this time, the blocking mechanism opens to allow water and liquid medicine to enter the drug adding cylinder 2, and can be stirred and diluted at the same time.

[0030] The outer wall of the dosing cylinder 2 is provided with a limiting rod 25, and the liquid storage cylinder 5 is detachably connected to the dosing cylinder 2 through the limiting rod 25. The top of the liquid storage cylinder 5 is provided with a sealing cover, and the sealing cover is provided with a port, and water and liquid medicine are injected into the liquid storage cylinder 5 at the port.

[0031] Specifically, a partition 26 is further provided in the dosing cylinder 2, and the lifting cylinder 3 extends upward through the partition 26. The partition 26 is provided with a plurality of air holes. When the lifting cylinder 3 rises, it drives the sealing piston disk 31 to approach the partition 26, and the air between the sealing piston disk 31 and the partition 26 is discharged through the air holes. A rotating shaft 4 is provided in the lifting cylinder 3, and the circumference of the rotating shaft 4 is provided with a spiral protrusion 41. The inner wall of the lifting cylinder 3 is provided with a spiral depression that cooperates with the spiral protrusion 41. The bottom end of the rotating shaft 4 extends downward through the sealing piston disk 31, and the inner bottom surface of the dosing cylinder 2 is provided with a base plate 43. The rotating shaft 4 is rotatably connected to the base plate 43 through a connecting shaft 44. The rotating mechanism includes multiple groups of extension rods 42, and the extension rods 42 are fixed on the circumferential surface of the rotating shaft 4 and the connecting shaft 44. When the lifting cylinder 3 is lifted, it drives the rotating shaft 4 to rotate in the lifting cylinder 3, and the liquid medicine enters the dosing cylinder 2 and is stirred by the extension rod 42 at the same time.

[0032] In this embodiment, there are two ways to lift the sealing piston disc 31: one is to directly pull the lifting cylinder 3 upward. At this time, the spiral protrusion 41 cooperates with the spiral recess in the lifting cylinder 3. When the sealing piston disc 31 rises, the rotating shaft 4 rotates accordingly. After the rotating shaft 4 rotates, the extension rod 42 at the bottom rotates accordingly, thereby satisfying the requirement of taking in water and liquid medicine while stirring and diluting; the other is to actively rotate the rotating shaft 4. After the rotating shaft 4 rotates, the spiral protrusion 41 cooperates with the spiral recess in the lifting cylinder 3 to drive the lifting cylinder 3 and the sealing piston disc 31 to rise. After the rotating shaft 4 actively rotates, the extension rod 42 at the bottom rotates accordingly, and at the same time, the sealing piston disc 31 rises to generate negative pressure, so that water and liquid medicine enter the dosing cylinder 2. The above two methods can both satisfy the requirement of taking in water and liquid medicine while stirring and diluting.

[0033] In this embodiment, the automatic opening and closing of the L-shaped connecting pipe 23 is achieved by a closing mechanism. Specifically, the closing mechanism includes a guide pipe 231, a tension spring 232 and a sealing plug 233. One end of the guide pipe 231 is fixed at the inner corner of the L-shaped connecting pipe 23, and the other end of the guide pipe 231 extends toward the dosing cartridge 2. The tension spring 232 is arranged in the guide pipe 231, and the sealing plug 233 is arranged at the port of the L-shaped connecting pipe 23. One end of the tension spring 232 is fixedly connected to the inner wall of the L-shaped connecting pipe 23 in the guide pipe 231, and the other end is fixedly connected to the sealing plug 233. The tension spring 232 is always in a stretched state. In the stretched state, the sealing plug 233 is in close contact with the port of the L-shaped connecting pipe 23 to achieve a sealed seal.

[0034] Furthermore, the sealing plug 233 is hemispherical, and the outer diameter of the sealing plug 233 is larger than the inner diameter of the L-shaped connecting tube 23. When the sealing piston disc 31 moves upward, the sealing plug 233 moves into the dosing cylinder 2 and further stretches the tension spring.

[0035] Under normal circumstances, the tension spring 232 pulls the sealing plug 233 in the direction away from the dosing cylinder 2. At this time, the end of the L-shaped connecting pipe 23 is blocked by the sealing plug, and the water and liquid medicine in the liquid storage cylinder 5 cannot enter the dosing cylinder 2. When it is necessary to prepare medicine for termite control, the lifting cylinder 3 is pulled upward or the rotating shaft 4 is driven. At this time, the sealing piston disc 31 moves upward, so that negative pressure is generated inside the dosing cylinder 2. The force generated by the negative pressure causes the sealing plug 233 to start moving into the dosing cylinder 2, and at the same time the tension spring 232 will be further stretched. Figure 10 As shown, the length of the further stretched tension spring 232 increases, and the sealing plug 233 no longer contacts the end of the L-shaped connecting tube 23; at this time, the water and liquid medicine in the liquid storage cylinder 5 will enter the dosing cylinder 2 from the L-shaped connecting tube 23, and will be stirred and diluted while preparing the medicine.

[0036] After the medicine is prepared, the sealing valve on the medicine discharge pipe 24 is opened to discharge the internal medicine. The medicine flows along the embankment and penetrates into the gaps between bricks and stones, thereby increasing the termite control effect. At the same time, the internal and external pressures are restored. At this time, the further stretched tension spring 232 will contract and pull back the sealing plug 233, so that it continues to block the port of the L-shaped connecting pipe 23 to prevent it from leaking, which is also convenient for subsequent preparation of medicine.

[0037] As a preferred embodiment, the dosing cartridge 2 is arranged in the outer shell 1, and the outer shell 1 is in the shape of a semi-circular barrel. The outer wall of the outer shell 1 is provided with a push-pull handle 11, and a plurality of travel wheels 12 are provided at the bottom corners of the outer shell 1. When moving, the push-pull handle is pulled, and the whole moves through the travel wheel 12. The end face of the outer shell 1 is provided with a Z-shaped angle iron 13, one end of the Z-shaped angle iron 13 is connected to the outer shell 1, and the bottom of the Z-shaped angle iron 13 is flush with the bottom of the travel wheel 12, so that the outer shell 1 remains stable as a whole when upright.

[0038] A protective strip 14 is also provided at the opening of the outer shell 1. The protective strip 14 contacts the outer walls of the two liquid storage cylinders 5 to limit the liquid storage cylinders. The protective strip 14 is detachably connected to the outer shell 1, which is convenient for taking and placing the liquid storage cylinders and increases the practicality of the device.

[0039] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
