Description

Technical Field

[0001] The utility model relates to the technical field of termite control, in particular to an underground medicine injector for termite control. Background Technique

[0002] Termites are common pests that can erode wood and cellulose, causing serious damage to buildings and the ecological environment.

[0003] Termite control refers to taking various measures to prevent and control the harm of termites to buildings, forests, water conservancy facilities, etc. At present, the effect of controlling termites by the liquid medicine perfusion method is better than that of the trapping method. The liquid medicine perfusion method sprays the medicine underground through a nozzle to kill or drive away termites. The advantage of the underground medicine injector for termite control is that the dosage of the medicine can be accurately controlled, avoiding environmental pollution caused by excessive use of the medicine. At the same time, since the medicine is directly injected underground, termites can be more effectively killed or driven away.

[0004] An underground medicine injector for termite control described in the prior art has a motor bracket under the mounting plate. Limiting rods are provided on both sides of the mounting plate and located on both sides of the motor bracket. A motor is provided inside the motor bracket. The output end of the motor extends out of the motor bracket and is provided with a rotating plate. A connecting sleeve is provided under the rotating plate. An injection cylinder that can rotate with the connecting sleeve is provided inside the connecting sleeve. Positioning blocks are provided on both side surfaces of one end of the injection cylinder located outside the connecting sleeve. The positioning blocks are respectively fixedly connected to the adjacent limiting rods. A rectangular injection cavity is provided inside the injection cylinder. A rectangular push plate is provided inside the injection cavity. A piston is provided under the push plate. A push rod is provided on the upper surface of the push plate. A push handle is provided on the upper surface of the push rod. The push handle is threadedly connected to the connecting sleeve. Support frames are provided on the outer side surfaces of the limiting rods away from each other and near the lower end.

[0005] The above-mentioned underground medicine injector for termite control replaces manual pushing of the injection liquid with machinery, reducing the labor intensity.

[0006] However, for the above-mentioned underground medicine injector for termite control, after the nozzle connected to the bottom of the injection cylinder is vertically inserted into the ground, the liquid medicine inside the injection cylinder is extruded by an external force for medicine administration. The position of the nozzle always remains vertically downward, resulting in uneven medicine administration. Moreover, after the nozzle is vertically inserted into the ground, the soil is not soft enough, resulting in poor distribution of the liquid medicine after medicine administration, affecting the termite control effect. Content of the Utility Model

[0007] The purpose of the utility model is to provide an underground medicine injector for termite control to solve the problems raised in the above background technique.

[0008] To achieve the above purpose, the utility model provides the following technical solutions:

[0009] An underground medicine injector for termite control, comprising a medicine delivery rod and a medicine delivery head connected to the bottom of the medicine delivery rod. The medicine delivery head is arranged in a conical structure. A sleeve is sleeved on the outer circumferential wall of the medicine delivery rod above the medicine delivery head. A component for softening underground soil for termite control is arranged between the sleeve and the medicine delivery head. A plurality of medicine delivery holes are uniformly and penetratingly formed on the outer circumferential wall of the top of the medicine delivery head.

[0010] As a preferred solution of the present utility model, the component for softening underground soil for termite control includes a rotating disk, a fixing ring and an expanding displacement plate. The fixing ring is fixedly located at the top of the medicine delivery head. The rotating disk is located at the top of the fixing ring. Three arc-shaped rotating grooves are uniformly formed on the rotating disk. Three sliding blocks corresponding to the positions of the arc-shaped rotating grooves are uniformly and slidably arranged on the fixing ring at the bottom of the rotating disk. The top of each sliding block extends into the corresponding arc-shaped rotating groove through a connecting column. Three expanding displacement plates are provided. The expanding displacement plates are sequentially fixed to one end of the outer wall of the sliding blocks located between the rotating disk and the fixing ring.

[0011] As a preferred solution of the present utility model, the expanding displacement plate is an arc-shaped blade.

[0012] As a preferred solution of the present utility model, the rotating disk is rotatably sleeved on the outer circumferential wall of the medicine delivery rod below the sleeve through a bearing. The medicine delivery rod is arranged in a hollow structure with both ends penetrating.

[0013] As a preferred solution of the present utility model, the bottom of the sleeve is connected to the top of the rotating disk.

[0014] As a preferred solution of the present utility model, the medicine delivery rod is arranged in a hollow structure with both ends penetrating. One end of the bottom of the medicine delivery rod is connected to the medicine delivery head in a penetrating manner. One section of the top of the medicine delivery rod is connected to an external liquid supply pump for termite control.

[0015] As a preferred solution of the present utility model, the diameter of the rotating disk is less than or equal to the diameter of the top of the medicine delivery head.

[0016] As a preferred solution of the present utility model, a limiting block is arranged on the outside of the medicine delivery rod at the top of the sleeve.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] Aiming at the problems raised in the background art, after the underground medicine injector of the present application is inserted into the ground, after the contact area with the underground soil is enlarged by the component for softening underground soil for termite control, the soil is made soft and has gaps by lifting. Then, multi-angle medicine delivery is carried out at the gaps through the 360-degree medicine delivery holes on the medicine delivery head. The medicine is uneven, and the liquid medicine is evenly distributed after the soil is softened and medicated, ensuring the termite control effect.

[0019] When in use, insert the dosing head at the end of the dosing rod into the ground interior, rotate the sleeve, and the sleeve drives the rotating disc to rotate. While the rotating disc is rotating, the connecting column inside the arc-shaped rotating groove on the rotating disc drives the sliding block to move outward on the fixed ring at the same time. While the sliding block is moving, the expansion displacement plate connected to it moves into the soil on the outer circumference of the dosing rod. At this time, the soil is located on the expansion displacement plate, increasing the contact area with the soil. Lift the dosing rod upward. At this time, the soil becomes soft and has gaps. While lifting, drive the dosing head to be at the soil gap. Start the external termite control liquid supply pump, and perform multi-angle dosing at the gap through the 360-degree dosing holes on the dosing head. After dosing, rotate the sleeve in the reverse direction to drive the rotating disc to rotate. While the rotating disc is rotating, the connecting column inside the arc-shaped rotating groove on the rotating disc drives the sliding block to move inward on the fixed ring at the same time. While the sliding block is moving, the expansion displacement plate connected to it resets, and then pull out the dosing rod;

[0020] Using the expansion displacement plate to expand the soil contact area and make it soft helps the medicament to be more evenly distributed in the soil, enhancing the control effect. By rotating the sleeve, the expansion and reset of the soil are controlled, simplifying the operation process and improving work efficiency. The dosing head is designed with 360-degree dosing holes, which can achieve full-range dosing at the soil gap, effectively covering the possible activity areas of termites, and the dosing strategy can be adjusted according to different soil properties and termite control requirements, having good environmental adaptability.

[0031] Please refer to Figure 1 、 2 Figures 3 and 4, the underground soil softening component for termite control includes a rotating disk 4, a fixed ring 41 and an expansion displacement plate 43. The fixed ring 41 is fixedly located at the top of the medicine delivery head 2. The rotating disk 4 is located at the top of the fixed ring 41. Three arc-shaped rotating grooves 401 are uniformly formed on the rotating disk 4. Three sliding blocks 410 corresponding to the positions of the arc-shaped rotating grooves 401 are uniformly and slidably arranged on the fixed ring 41 at the bottom of the rotating disk 4. The top of each sliding block 410 extends into the corresponding arc-shaped rotating groove 401 through a connecting column 411. There are three expansion displacement plates 43 in total. The expansion displacement plates 43 are sequentially fixed to one end of the outer wall of the sliding blocks 410 between the rotating disk 4 and the fixed ring 41; the expansion displacement plates 43 are arc-shaped blades; the rotating disk 4 is rotatably sleeved on the outer circumferential wall of the medicine delivery rod 1 below the sleeve 3 through a bearing. The medicine delivery rod 1 is arranged in a hollow structure with both ends penetrating; the bottom of the sleeve 3 is connected to the top of the rotating disk 4; the diameter of the rotating disk 4 is less than or equal to the diameter of the top of the medicine delivery head 2.

[0032] It should be noted that, in this embodiment, the diameter of the rotating disk 4 is less than or equal to the diameter of the top of the medicine delivery head 2, which ensures that the rotating disk 4 will extend below the soil when the medicine delivery head 2 is inserted into the soil, ensuring the subsequent softening of the soil;

[0033] Furthermore, the expansion displacement plate 43 is an arc-shaped blade made of stainless steel, ensuring that when the contact area with the soil is increased, the expansion displacement plate 43 can easily penetrate into the soil when it expands and displaces towards the outer circumferential wall;
