Description

Technical Field

[0001] This utility model relates to the field of pest control technology, and more specifically, to a high-pressure directional injection device for termite control. Background Technology

[0002] Termites, as a type of insect pest that is both covert and destructive, pose a serious threat to building maintenance, agricultural and forestry protection, and home environment management. Their activities are usually hidden inside wood, deep in the soil, or in the cracks of building structures, making them difficult to detect in the early stages. Once discovered, they often cause significant damage, not only harming wooden furniture and decorative materials but also potentially affecting the structural stability of buildings, thus adversely impacting people's production and lives. In current termite control practices, the injection method has become a widely used technique because it can directly deliver the control solution to termite nests or activity areas, achieving deep penetration and precise extermination.

[0003] Chinese Patent Publication No. CN218164106U discloses a grouting device for termite control. This solution utilizes the internal grout mixing chamber and stirring rod of the grouting device body to achieve stable and uniform mixing of grout and pesticides without coagulation. Through the connection between the bottom of the grouting device body's conveying pump and two sets of diversion pipes, and the assembly of the external flow control valves of the two sets of diversion pipes with the grouting mechanism, multiple grouting mechanisms can be stably installed in the required positions by grounding the threaded plug rods at the upper limit plate of the grouting mechanism. Furthermore, by switching the conveying pump and flow control valves, the mixed grout can be stably delivered to multiple grouting mechanisms, facilitating convenient and efficient single-person, multi-point operation. However, in practical implementation, the following drawbacks exist: when the grout is exhausted, the machine must be stopped for replenishment, causing an interruption in the grouting operation. This interruption not only wastes operation time but also provides termites with an opportunity to detect the danger and migrate, leading to some termites escaping and significantly reducing the control effect.

[0004] Therefore, a high-pressure directional injection device for termite control is proposed to address the above problems. Utility Model Content

[0029] Example 1:

[0030] Please see Figure 1 - Figure 3 A high-pressure directional injection device for termite control includes a base plate 1. Multiple casters 2 with brakes are fixedly connected to the lower end of the base plate 1. A push rod 3 is fixedly connected to the upper end of the base plate 1. An injection mechanism 4 and a stirring mechanism 5 are also fixedly connected to the upper end of the base plate 1. The injection mechanism 4 includes two material buckets 41, both of which are fixedly installed on the upper end of the base plate 1. Each of the two material buckets 41 has a discharge box 42 fixedly connected to one side. Connecting pipes 4 are fixedly connected to and communicate with the inner surfaces of both discharge boxes 42. 3. Valves 44 are provided on the outer surfaces of the two connecting pipes 43. The outer surfaces of the two connecting pipes 43 are fixedly connected to and communicate with a transfer box 45. The transfer box 45 is fixedly installed on the upper end of the base plate 1. A grouting pump 46 is fixedly connected to the upper end of the transfer box 45. An extraction pipe 47 is fixedly connected to and communicates with the inlet end of the grouting pump 46. The outer surface of the extraction pipe 47 is fixedly connected to and communicates with the inner cavity of the transfer box 45. A connector 48 is fixedly connected to the outlet end of the grouting pump 46. An injection assembly 49 is fixedly connected to and communicates with the inside of the connector 48.

[0031] The infusion assembly 49 includes an infusion tube 491, which is fixedly installed in the inner cavity of the connector 48. A one-way valve 492 is provided on the outer surface of the infusion tube 491. A connecting plate 493 is fixedly connected to the outer surface of the one-way valve 492. Multiple insertion rods 494 are fixedly connected to one side of the connecting plate 493.

[0032] The one-way valve 492 is a CL-type high-pressure one-way valve, which can effectively prevent slurry from flowing back from the injection pipe 491 into the transfer box 45.

[0033] This solution involves inserting the injection pipe 491 into the ant nest entrance and opening the one-way valve 492. Then, multiple insert rods 494 on one side of the connecting plate 493 are inserted into the soil or wooden structure next to the ant nest entrance. Through the fixing effect of the insert rods 494, the injection pipe 491 is kept in a directional state and is always located in the ant nest entrance.

[0034] By opening the valve 44 corresponding to the material bucket 41, the slurry in the material bucket 41 flows into the connecting pipe 43 through the outlet box 42, and then is transported to the transfer box 45 through the connecting pipe 43; by starting the grouting pump 46, the inlet end draws slurry from the transfer box 45 through the extraction pipe 47, and after being pressurized by the grouting pump 46, it is transported to the grouting pipe 491 of the grouting component 49 through the connector 48 at the outlet end and sprayed out under high pressure from the outlet of the grouting pipe 491, accurately injecting it into the termite nest or the area where the pest is active, thus achieving directional grouting.

[0035] When the slurry in the first material tank 41 is about to run out, the valve 44 corresponding to the second material tank 41 can be opened. At this time, both material tanks 41 simultaneously supply the pesticide solution to the transfer box 45. When the pesticide solution in the first material tank 41 is consumed, its corresponding valve 44 is closed and the pesticide solution is mixed again in the first material tank 41. This cycle can be repeated continuously throughout the process, greatly improving the prevention and control effect.

[0036] Please see Figure 4 - Figure 5 The stirring mechanism 5 includes a U-shaped frame 51, which is fixedly installed on the upper end of the base plate 1. A motor 52 is fixedly connected to the top wall of the inner cavity of the U-shaped frame 51. A rotating block 53 is fixedly connected to the output end of the motor 52 through a coupling. Two guide rods 54 are fixedly connected to the upper end of the rotating block 53. A support plate 55 is fixedly connected to the upper end of the two guide rods 54. A motor 56 is fixedly connected to the upper end of the support plate 55. A lead screw 57 is fixedly connected to the output end of the motor 56 through a coupling. A stirring assembly 58 is threadedly connected to the outer surface of the lead screw 57.

[0037] Motor 52 is a Panasonic MSMD012G1U servo motor, which drives the rotating block 53 to move the stirring assembly 58 to switch positions above the two material buckets 41.

[0038] Motor 2 56 uses a Leadshine 57HS22 stepper motor, which drives the stirring assembly 58 to rise and fall through the lead screw drive.

[0039] The stirring assembly 58 includes a movable block 581, which is threaded onto the outer surface of the lead screw 57. A lifting plate 582 is fixedly connected to the outer surface of the movable block 581. The lifting plate 582 is slidably mounted on the outer surface of two guide rods 54. A reinforcing slider 583 is fixedly connected to the upper end of the movable block 581. The reinforcing slider 583 is slidably mounted on the outer surface of the two guide rods 54. A motor 584 is fixedly connected to the upper end of the lifting plate 582. The output end of the motor 584 is fixedly connected to a stirring roller 585 via a coupling. Multiple stirring plates 586 are fixedly connected to the outer surface of the stirring roller 585.

[0040] Motor 3 584 uses Chint Y2-80M1-4 three-phase asynchronous motor, which can drive the stirring roller 585 and the stirring plate 586 to rotate to achieve slurry mixing.

[0041] This solution starts motor 52, which drives the rotating block 53 to rotate via a coupling. The two guide rods 54 on the upper end of the rotating block 53 rotate synchronously with the rotating block 53, thereby driving the support plate 55, motor 56, lead screw 57 and stirring assembly 58 to rotate as a whole, so that the stirring assembly 58 can switch positions between the two material tanks 41.

[0042] By starting motor 56, the output end of motor 56 drives screw 57 to rotate through coupling. Since moving block 581 is threaded on the outer surface of screw 57, and lifting plate 582 and reinforcing slider 583 are slidably installed on the outer surfaces of two guide rods 54, the rotation of screw 57 drives moving block 581 to move downward along the axial direction of screw 57. Moving block 581 simultaneously drives lifting plate 582 and reinforcing slider 583 to slide downward synchronously along guide rod 54, so that stirring roller 585 and stirring plate 586 can be fully inserted into material bucket 41.

[0043] By starting motor 3584, the output end of motor 3584 drives the stirring roller 585 to rotate through the coupling. The stirring plate 586 on the outer surface of the stirring roller 585 rotates synchronously with the stirring roller 585, which allows the drug and liquid to come into full contact and the mixture to be stirred evenly, ensuring that the concentration of the prepared injection slurry is consistent.

[0044] It should be noted that the motor 1 52, motor 2 56, motor 3 584, valve 44, check valve 492, etc. in this utility model are powered by a power supply and controlled by a controller.

[0045] The controller uses the INVT IVC1L-1208MAR compact PLC as the control core of the device. It undertakes the logic scheduling and parameter adjustment tasks of all electrical components and can realize linkage operations such as motor start-stop, speed adjustment, valve switching, and grouting pressure control through pre-programmed programs.

[0046] It should be noted that the specific installation methods, circuit connection methods, oil circuit connection methods, and control methods of motor 1 52, motor 2 56, motor 3 584, valve 44, and check valve 492 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0047] Working principle:

[0048] The push rod 3 at the top of the base plate 1 can be used to move the device to the termite control site with the help of the movable wheel 2 with a brake structure. After reaching the work position, the brake structure of the movable wheel 2 can be stepped on to lock the movable wheel 2, keep the equipment stable, and prevent slippage during the operation.

[0049] After adding the prepared medicine and water to the first material tank 41 of the injection mechanism 4, start the second motor 56. The output end of the second motor 56 drives the lead screw 57 to rotate through the coupling. Since the moving block 581 is threaded on the outer surface of the lead screw 57, and the lifting plate 582 and the reinforcing slider 583 are respectively slidably installed on the outer surface of the two guide rods 54, the rotation of the lead screw 57 drives the moving block 581 to move downward along the axial direction of the lead screw 57. At the same time, the moving block 581 drives the lifting plate 582 and the reinforcing slider 583 to slide downward synchronously along the guide rod 54. When the stirring roller 585 and the stirring plate 586 are fully inserted into the slurry, stop the action of the second motor 56.

[0050] Start motor 3 584 so that the output end of motor 3 584 drives the stirring roller 585 to rotate through the coupling. The stirring plate 586 on the outer surface of the stirring roller 585 rotates synchronously with the stirring roller 585, making full contact with the slurry and stirring it evenly, so that the medicine and water in the first material bucket 41 are fully mixed, ensuring that the concentration of the prepared grouting slurry is consistent.

[0051] During the preparation of the medicine, the injection pipe 491 can be inserted into the ant nest opening and the one-way valve 492 can be opened. Multiple rods 494 on one side of the connecting plate 493 can be inserted into the soil or wooden structure next to the ant nest opening. Through the fixing effect of the rods 494, the injection pipe 491 can be kept in a directional state and always located in the ant nest opening.

[0052] After the slurry in the first bucket 41 is stirred evenly, the valve 44 corresponding to the bucket 41 is opened, allowing the slurry in the bucket 41 to flow into the connecting pipe 43 through the outlet box 42, and then be transported to the transfer box 45 through the connecting pipe 43. The grouting pump 46 is then started, allowing its inlet end to draw slurry from the transfer box 45 through the extraction pipe 47. After being pressurized by the grouting pump 46, the slurry is transported to the grouting pipe 491 of the grouting component 49 through the connector 48 at the outlet end and sprayed out under high pressure from the outlet of the grouting pipe 491, accurately injecting it into the termite nest or the area where the pest is active, thus achieving directional grouting.

[0053] Simultaneously, motor 52 is started, and its output drives the rotating block 53 to rotate via a coupling. The two guide rods 54 on the upper end of the rotating block 53 rotate synchronously with the rotating block 53, thereby driving the support plate 55, motor 56, lead screw 57, and mixing assembly 58 to rotate as a whole. This causes the mixing roller 585 and mixing plate 586 to rotate directly above the opening of the second material tank 41. The medicine solution is mixed in the second material tank 41 to prepare for continuous grouting. When the grout in the first material tank 41 is about to run out, the valve 44 corresponding to the second material tank 41 can be opened. At this time, both material tanks 41 simultaneously supply medicine solution to the transfer box 45. When the medicine solution in the first material tank 41 is consumed, its corresponding valve 44 is closed. The above operation is repeated to mix the medicine solution in the first material tank 41 again. This cycle can be repeated continuously throughout the process, greatly improving the prevention and control effect.

[0054] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
