Detailed Description of the Preferred Embodiment

[0031] This specific embodiment is a grouting device for termite nests, and its structural schematic diagram is as Figures 1 - 9 shown, including a vehicle frame 1. The vehicle frame 1 is arranged in an L shape. A mounting frame 2 is fixedly connected to the top of the vehicle frame 1. The mounting frame 2 is arranged in a U shape. A tank body 3 is movably connected between the front and rear inner walls of the mounting frame 2 through a rotating shaft and a bearing. The bottom of the tank body 3 is arranged in a conical shape. Fixed plates 4 are symmetrically and fixedly connected to the inner wall of the tank body 3. A transmission rod 5 is arranged in the tank body 3. Both ends of the transmission rod 5 penetrate through the fixed plates 4 and are movably connected to the fixed plates 4. A motor 6 is installed on the top of the upper fixed plate 4. The output end of the motor 6 is fixedly connected to the top end of the transmission rod 5. A spiral blade 8 is fixedly connected to the side wall of the transmission rod 5 near the bottom. A turning control mechanism is arranged on the front wall of the mounting frame 2. A delivery pipe 9 is fixedly connected to the bottom of the tank body 3. One end of the delivery pipe 9 is fixedly connected to a grouting pipe 10. A blocking mechanism is arranged on the side wall of the grouting pipe 10.

[0032] As Figure 1 and Figure 7 shown, the turning control mechanism includes a circular plate 26. One end of the rotating shaft on the tank body 3 passes through the inner ring of the bearing and is fixedly connected to the circular plate 26. A pull rod 28 is slidably connected to the front wall of the mounting frame 2. Positioning openings 27 are symmetrically formed on the front wall of the circular plate 26. One end of the pull rod 28 extends into the positioning opening 27. A stop block 31 is fixedly connected to the front wall of the mounting frame 2. A third spring 29 is fixedly connected between the stop block 31 and the pull rod 28. The turning mechanism can fix the position of the tank body 3 and can also release the tank body 3, enabling the tank body 3 to rotate. In this way, when the tank body 3 is not in use, the opening of the cleaned tank body 3 can be downward, so that the liquid inside the tank body 3 can be drained. Among them, the material of the pull rod 28 is steel. The relatively hard steel material can stably hold the circular plate 26, improving the stability of use.

[0033] As Figures 1 to 9As shown, the plugging mechanism includes an annular shell 11, the bottom of the annular shell 11 is not closed, the annular shell 11 is assembled on the side wall of the grouting pipe 10, and round rods 12 are symmetrically arranged in the annular shell 11. The top of the round rod 12 passes through the annular shell 11 and is movably connected to the annular shell 11. A sealing plate 13 is arranged in the annular shell 11, and the bottom end of the round rod 12 is fixedly connected to the sealing plate 13. The inner wall and the outer wall of the sealing plate 13 are symmetrically provided with annular grooves 19, and the two annular grooves 19 are equipped with sealing rings 20. A pressing plate 14 is movably connected to the side wall of the grouting pipe 10, and the top of the round rod 12 is fixedly connected to the bottom of the pressing plate 14. A positioning mechanism is provided on the top of the pressure plate 14, and a rubber airbag 17 is fixedly connected to the side wall of the grouting pipe 10. The rubber airbag 17 is arranged in an annular shape, and the top of the rubber airbag 17 is fixedly connected to the bottom of the annular shell 11 near the edge. A conical ring 18 is installed on the side wall of the grouting pipe 10 near the bottom, wherein the sealing ring 20 is a sealing ring 20 made of rubber material commonly available on the market. The rubber airbag 17 is arranged in a conical shape after inflation, and the bottom is relatively flat after inflation, which can improve the sealing effect, wherein the conical ring 18 can widen the entrance of the termite nest, so that the rubber airbag 17 can easily enter the termite nest to seal the hole.

[0034] like Figure 3 and Figure 8 As shown, the positioning mechanism includes a U-shaped plate 21, which is fixedly connected to the pressing plate 14, an L-shaped rod 22 is arranged above the pressing plate 14, and evenly distributed positioning grooves 25 are opened on the side wall of the grouting tube 10, one end of the L-shaped rod 22 passes through the U-shaped plate 21 and extends into the positioning groove 25, a rectangular plate 24 is fixedly connected to the top of the pressing plate 14, and a second spring 23 is fixedly connected between the rectangular plate 24 and the L-shaped rod 22, wherein the bottom of the right end of the L-shaped rod 22 is arranged in an arc shape, so that when the pressing plate 14 descends, there is no need to pull the L-shaped rod 22, and the L-shaped rod 22 can be moved to the left to squeeze the second spring 23 through the arc-shaped end face, and the pressing plate 14 can stay at any position on the grouting tube 10 through a plurality of positioning grooves 25, so that the rubber airbag 17 can adapt to holes of different sizes to avoid the need to be filled with air each time it is used.

[0035] like Figure 2 As shown, a stirring rod 7 is fixedly connected to the side wall of the transmission rod 5. There are several stirring rods 7 and they are arranged in a ring array. The stirring rods 7 can rotate along with the transmission rod 5. During the rotation, the slurry can be stirred to prevent the slurry from solidifying. The purpose of the array arrangement is to ensure that the transmission rod 5 is evenly stressed during rotation to increase the service life.

[0036] The pull rod 28 is L-shaped, a slider is fixedly connected to the rear side wall of the pull rod 28, and a slide groove matching the slider is provided on the front wall of the mounting frame 2. The slider and the slide groove can prevent the pull rod 28 from falling, thus playing a limiting role.

[0037] In addition, a limiting plate 15 is fixedly connected to the outer wall of the annular shell 11 near the bottom. A first spring 16 is symmetrically and fixedly connected between the limiting plate 15 and the pressing plate 14. When the rubber airbag 17 is not in use, the first spring 16 can rebound to push the pressing plate 14 and the sealing plate 13 upward, playing a role of automatic rebound.

[0038] As Figure 1 shown, a placing rack 30 is fixedly connected to the bottom of the inner cavity of the vehicle frame 1. The placing rack 30 is arranged in a U shape. There are two placing racks 30, which are respectively located on the left and right sides of the grouting pipe 10. In this way, when the grouting pipe 10 is not in use, it can be placed on the two placing racks 30, which is convenient for taking and improves the convenience of use. Moreover, the placing rack 30 is made of steel.

[0039] Working principle: When this technical solution is in use, first pour the configured ant-killing slurry into the tank body 3, then push the vehicle frame 1 to the place where it is needed. Next, remove the grouting pipe 10 from the placement rack 30, and insert the grouting pipe 10 and the conical ring 18 into the termite nest, and make the rubber airbag 17 enter the termite nest. Then, the pressing plate 14 can be pushed downward to compress the first spring 16. Synchronously, the sealing plate 13 is pushed downward by the pressing plate 14 through the round rod 12, so as to achieve the effect of inflating the rubber airbag 17. When the pressing plate 14 descends, the L-shaped rod 22 will repeatedly push the second spring 23, so that the L-shaped rod 22 disengages from the positioning groove 25. When the pressing plate 14 descends to the limit position, the second spring 23 synchronously pushes the L-shaped rod 22 into the positioning groove 25 to fix the position of the pressing plate 14, thereby fixing the expanded rubber airbag 17. In this way, the rubber airbag 17 expands and squeezes the inner wall of the termite nest, achieving the effect of blocking the termite nest, preventing the slurry from overflowing and some termites from running out. Next, start the motor 6 through an external power supply. The motor 6 drives the spiral blade 8 to rotate forward. The spiral blade 8 rotates forward to convey the slurry in the tank body 3 into the delivery pipe 9 and the grouting pipe 10. Then, the slurry will enter the termite nest through the grouting pipe 10 to achieve the purpose of grouting. When the grouting is completed, turn off the motor 6 and pull the L-shaped rod 22 to compress the second spring 23, so that the L-shaped rod 22 disengages from the positioning groove 25. Synchronously, the first spring 16 pushes the pressing plate 14 to rise. In this way, the air in the rubber airbag 17 will be sucked into the annular shell 11, causing the rubber airbag 17 to contract. Then, the conical ring 18 and the grouting pipe 10 can be retracted and placed on the placement rack 30. After the grouting is completed, if it is necessary to move the vehicle frame 1, in order to prevent the slurry from solidifying during the movement, the motor 6 can be started to rotate reversely through an external control power supply. The motor 6 drives the transmission rod 5 and the stirring rod 7 to rotate reversely to stir the slurry, which can effectively prevent the slurry from solidifying and can effectively improve its use efficiency. Finally, if it is necessary to clean the tank body 3, pull the pull rod 28 to compress the third spring 29, so that the pull rod 28 disengages from the positioning opening 27. Then, the tank body 3 can be rotated so that the opening of the tank body 3 can be inverted. In this way, it is more convenient to clean the tank body 3. After the cleaning is completed, rotate the tank body 3 back to its original position and fix its position with the pull rod 28.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of this technical solution is within the protection scope of the present invention.
