[0028] First embodiment: please refer to Figure 1The application provides an ant nest breaking and root treating pesticide applicator 106, which comprises a holding cylinder, an insertion cylinder and a pesticide application assembly, the holding cylinder comprises a holding rod 101 and a soil breaking pipe 102, the soil breaking pipe 102 is arranged below the holding rod 101, and a pesticide application channel is arranged in the holding rod 101 and the soil breaking pipe 102; the insertion cylinder comprises a cylinder body 103 and a position limiter 104, a plurality of liquid outlet holes 105 are arranged on the cylinder body 103, the cylinder body 103 is slidably connected with the soil breaking pipe 102, the position limiter 104 is rotatably connected with the holding rod 101 and threadedly connected with the cylinder body 103, and the pesticide application assembly is in communication with the pesticide application channel.

[0029] In the embodiment, the holding cylinder serves as an operation main body and is used for providing support and force, and comprises the holding rod 101 and the soil breaking pipe 102. The holding rod 101 is located at the upper portion and has a long rod shape, so that the user can stably hold and apply downward pressure. The soil breaking pipe 102 is arranged below the holding rod 101 and has a whole conical shape or a conical drill bit structure, is made of high-strength metal material, has good soil breaking capacity and wear resistance, can easily penetrate the soil, turf or soft stratum and reach the depth of the ant nest.

[0030] A pesticide application channel is arranged through the holding rod 101 and the soil breaking pipe 102, the channel extends from the top end of the holding rod 101 to the bottom end of the soil breaking pipe 102, forms a continuous pesticide delivery path, and is used for delivering the pesticide in the external pesticide source or the built-in pesticide bag to the underground nest area.

[0031] The cylinder body 103 of the insertion cylinder has a hollow tubular structure, and a plurality of liquid outlet holes 105 are uniformly distributed on the outer wall of the cylinder body 103. The liquid outlet holes 105 can be designed to have different hole diameters and distribution densities according to the size of the ant nest and the soil density, so that the pesticide can be uniformly and multi-directionally penetrated into each corner of the ant nest after the cylinder body 103 is inserted. The upper end of the cylinder body 103 is slidably connected with the inside of the soil breaking pipe 102.

[0032] In use, first, the holding rod 101 is held to insert the insertion cylinder into the soil layer at the position of the ant nest, then the position limiter 104 is rotated to disconnect the cylinder body 103 and the holding rod 101, the holding rod 101 is lifted, the cylinder body 103 is fixed in the soil layer by the friction force with the soil, the holding rod 101 is lifted to move the soil breaking pipe 102 into the cylinder body 103, the pesticide application assembly is started, the pesticide is delivered into the inside of the cylinder body 103 through the pesticide application channel, and is sprayed out of the liquid outlet holes 105 on the cylinder body 103 at high pressure, rapidly spreads into the inside of the ant nest, kills adult ants, larva ants and eggs, and fundamentally eliminates the ant problem. In addition, in order to make it more convenient to enter and exit the soil layer, a sleeve that can slide can be arranged on the outside of the holding rod 101 to reduce the resistance of entering and exiting the soil layer.

[0033] The application is simple to operate, integrates nest breaking and pesticide application, significantly improves ant control efficiency and eradication rate, and is suitable for ant control in various scenes such as garden greening, farmland, and residential area.

[0034] The pesticide application assembly comprises a pesticide applicator 106, a connecting head 107, a connecting pipe 108, and a pesticide tank 109.

[0035] The connecting head 107 is arranged above the holding cylinder, is fixedly connected and sealingly communicated with the entrance end of the pesticide application channel at the top end of the holding rod 101. The connecting head 107 is usually made of corrosion-resistant metal or high-strength engineering plastic, and is internally provided with a sealing ring 120 or a threaded interface, so that leakage of the pesticide liquid during transportation is avoided, and good pressure resistance is achieved to withstand the internal pressure generated during operation of the pesticide applicator 106.

[0036] The connecting pipe 108 is a flexible pressure-resistant hose, one end of which is sealingly connected with the connecting head 107, and the other end of which is in communication with the pesticide applicator 106 and the pesticide tank 109. The connecting pipe 108 is made of a material (such as polyurethane or rubber) that is resistant to chemical corrosion, aging, and flexible, and can adapt to different operation angles and terrain conditions to ensure smooth flow of the pesticide liquid. The diameter and length of the connecting pipe 108 are designed according to actual use requirements, so that sufficient flow is ensured, and carrying and operation are facilitated.

[0037] The pesticide applicator 106 is a pesticide liquid pressurized conveying device, which can be in the form of a manual plunger pump, a manual air pressure type sprayer, or an electric high-pressure pump. When the manual pesticide applicator 106 is used, the user pushes the handle back and forth or shakes the rocker to form pressure in the closed pipeline, so that the pesticide liquid is pushed into the pesticide application channel through the connecting pipe 108 and the connecting head 107, and finally flows into the holding cylinder. When the electric pesticide applicator 106 is used, a micro pump body driven by a battery can realize automatic pressurization, thereby further reducing labor intensity and improving pesticide application efficiency. A pressure gauge and a flow regulating valve can also be arranged on the pesticide applicator 106 to facilitate control of the spraying pressure and the dose, and adapt to different ant nest densities and soil permeabilities.

[0038] The pesticide tank 109 is a pesticide liquid storage container, which is detachably installed in the connecting pipe 108, is usually a transparent or translucent plastic container, and is convenient for observing the remaining amount of the pesticide liquid. The pesticide tank 109 is provided with a filling opening and a vent hole at the top. The filling opening is provided with a sealing cover to prevent leakage or evaporation of the pesticide liquid. The vent hole can balance the air pressure inside and outside the tank to ensure smooth flow of the pesticide liquid. The outlet at the bottom of the pesticide tank 109 is connected with the connecting pipe 108 through a pipeline, and the pesticide liquid enters the conveying system under the action of negative pressure suction or positive pressure pushing of the pesticide applicator 106.

[0039] Second embodiment: please refer to Figures 2-6 On the basis of the first embodiment, the holding rod 101 has a guide block 110, and a guide groove is arranged on the barrel 103.

[0040] At least one guide block 110 is arranged on the inner wall or the outer wall of the holding rod 101, which is preferably a strip-shaped protruding structure made of metal or high-strength plastic, has good wear resistance and structural strength. The guide block 110 is arranged along the axial direction of the holding rod 101, and its length matches the stroke of the barrel 103, which is used to guide the linear motion of the barrel 103 in the soil breaking pipe 102.

[0041] Correspondingly, a guide groove matched with the guide block 110 is arranged on the outer wall of the barrel 103 of the insertion barrel. The guide groove is a long strip-shaped groove extending along the axial direction of the barrel 103, and its cross-sectional shape matches the guide block 110, for example, it can be rectangular, dovetail-shaped or T-shaped structure, so as to ensure that the guide block 110 can be stably embedded and smoothly slide in the groove. When the position limiter 104 drives the barrel 103 to move up and down through the thread, the guide block 110 synchronously slides in the guide groove, effectively limiting the circumferential rotation of the barrel 103, so that it can only move linearly along the axial direction. This guide structure not only improves the stability of the lifting of the barrel 103, but also avoids the problem of out-of-control of the direction of the liquid outlet hole 105 due to the rotation of the barrel 103, so as to ensure that the liquid can be accurately released according to the preset direction and depth, and improve the uniformity and coverage of the application of the liquid.

[0042] The holding barrel further comprises an anti-skid sleeve 111 arranged on the holding rod 101.

[0043] The anti-skid sleeve 111 is arranged on the outside of the holding rod 101 and located in the main area held by the user's hand. The anti-skid sleeve 111 is made of soft material with good elasticity, such as rubber, silicone or thermoplastic elastomer (TPE), and the surface is provided with anti-skid lines, such as diamond grid pattern, longitudinal ribs, wavy pattern or granular protrusions, to increase the friction between the hand and the holding rod.

[0044] The insertion barrel further comprises a plurality of stabilizing blocks 112 and a plurality of first elastic members 113, the plurality of stabilizing blocks 112 are slidingly arranged on the barrel 103 and located around the barrel 103, and the plurality of first elastic members 113 are used to support the plurality of stabilizing blocks 112 respectively. A taper ring 114 is arranged on the holding rod 101, so that when the holding rod 101 is lifted, the taper ring 114 pushes the plurality of stabilizing blocks 112 out into the soil layer at the same time to increase the stability.

[0045] The plurality of stabilizing blocks 112 are evenly distributed around the outer periphery of the barrel 103, preferably three to six, and are arranged at intervals along the circumferential direction of the barrel 103. Each stabilizing block 112 is installed in a mounting groove provided on the side wall of the barrel 103 by a sliding fit, and can slide in and out in the radial direction. The outer surface of the stabilizing block 112 is polished to have an arc shape or a beveled surface, which facilitates insertion into the soil while reducing resistance, and also forms a large contact area with the surrounding soil after deployment, thereby enhancing the gripping force.

[0046] A first elastic member 113 is connected to the inner side of each stabilizing block 112. The first elastic member 113 can be a compression spring, a rubber elastic column, or a corrugated elastic element, etc., which has the ability to recover from deformation. One end of the first elastic member 113 is fixed to the bottom or side wall of the mounting groove, and the other end abuts against the inner end surface of the stabilizing block 112, thereby providing an elastic pre-tightening force inwardly in the normal state, so that the stabilizing block 112 remains in a contracted state and closely adheres to the surface of the barrel 103. This design ensures that the stabilizing block 112 does not expand to increase resistance when the barrel is inserted downward into the soil, thereby ensuring a smooth and efficient soil breaking process.

[0047] A conical ring 114 structure is provided inside or at the lower part of the holding rod 101. The conical ring 114 is a conical ring-shaped component with a small upper part and a large lower part, and its inner diameter gradually increases from top to bottom. It is fixed inside the holding rod 101 and moves synchronously with the holding rod 101. When the holding rod 101 is lifted upward relative to the barrel 103 (for example, after completing the soil breaking action, preparing to apply pesticide at a deeper level or fixing the position of the equipment), the conical ring 114 moves upward and gradually enters the corresponding area at the upper end of the barrel 103.

[0048] Since the outer peripheral surface of the conical ring 114 is an inclined surface, it will come into contact with the inner end of each stabilizing block 112 during upward movement, and use the conical surface thrust to push the plurality of stabilizing blocks 112 outward in the radial direction, overcoming the contraction force of the first elastic member 113, so that the stabilizing blocks 112 extend out from the side of the barrel 103 and are embedded in the surrounding soil layer. This linkage design realizes the automatic anchoring function of "expanding when lifting" - as long as the operator lifts the holding rod 101 upward, the conical ring 114 will simultaneously push all the stabilizing blocks 112 to expand outward, like opening an umbrella, forming a radial support structure in the soil.

[0049] After the plurality of stabilizing blocks 112 are embedded in the soil layer, the frictional force and lateral disturbance resistance between the pesticide applicator 106 and the soil are significantly increased, effectively preventing the equipment from shaking or retreating due to the reaction force during high-pressure pesticide application, and ensuring that the pesticide can be stably and continuously injected into the deep part of the ant nest. At the same time, this structure also helps to maintain the directional consistency of the liquid outlet hole 105, avoiding uneven distribution of pesticide due to equipment deviation.

[0050] When the operation is completed, the holding rod 101 is pushed down, the conical ring 114 is lowered and separated from the contact with the stabilizing blocks 112, at this time the elastic force of the first elastic member 113 automatically pulls each stabilizing block 112 back to the mounting groove inside the barrel 103, and returns to a compact state, facilitating the smooth pulling of the whole machine from the soil, and the operation is simple and free from jamming.

[0051] The soil breaking pipe 102 comprises a soil breaking pipe body 115, a sliding sleeve 116 and a second elastic member 117, the soil breaking pipe body 115 is fixedly connected with the holding rod 101, the sliding sleeve 116 is slidingly arranged on the soil breaking pipe body 115, and the second elastic member 117 is arranged between the sliding sleeve 116 and the soil breaking pipe body 115, the soil breaking pipe 102 further comprises a sealing ring 118, the sealing ring 118 is fixed on the upper layer of the sliding sleeve 116, a sealing ring 120 is arranged in the barrel 103, after the conical ring 114 pushes out the stabilizing blocks 112, the sliding sleeve 116 and the sealing ring 118 are continuously moved upward by the second elastic member 117 to contact with the sealing ring 120 to close the gap between the soil breaking pipe body 115 and the barrel 103.

[0052] The barrel 103 has a chamfer 119, and the chamfer 119 is located below the barrel 103.

[0053] In order to facilitate the insertion of the barrel into the soil and reduce the front end resistance during the insertion process, avoid soil blocking the liquid outlet hole 105 or hindering the expansion of the stabilizing blocks 112, the lower end edge of the barrel 103 is provided with a chamfer 119 structure. The chamfer 119 is located at the lowermost outer edge of the barrel 103, and has a 30°-60° inclined surface or a circular arc transition form, which can guide the barrel 103 to smoothly cut into the soil during the descent process, and plays the role of a "guide head". The chamfer 119 not only reduces the insertion resistance, but also prevents soil particles from being stuck in the gap between the barrel 103 and the soil breaking pipe 102, and ensures the normal operation of the internal sliding parts.

[0054] The barrel further comprises a blocking ring 121, the blocking ring 121 is slidingly arranged in the barrel 103, and is used for closing the liquid outlet hole 105 when the barrel 103 is placed into the soil layer, and an outer boss arranged on the sliding sleeve 116 can lift the blocking ring 121 to open the liquid outlet hole 105 when the soil breaking pipe body 115 is lifted.

[0055] The insertion barrel further comprises a blocking ring 121, which is an annular sliding member coaxially arranged in the inner cavity of the barrel body 103 and can slide axially up and down along the barrel body 103. The outer diameter of the blocking ring 121 is slightly smaller than the inner wall of the barrel body 103, but larger than the inner diameter of the area where the liquid outlet hole 105 is located. A small gap is provided between the outer edge of the blocking ring 121 and the inner wall of the barrel body 103, which can ensure smooth sliding and also has a certain sealing capacity. The initial position of the blocking ring 121 is located in the coverage area of the liquid outlet hole 105. When the barrel body 103 has not started to administer medicine and is in the stage of being inserted into the soil layer, the blocking ring 121 is in the low position under the weight or the assistance of the elastic member, and the side wall thereof blocks the plurality of liquid outlet holes 105 on the side wall of the barrel body 103, forming a physical closure and effectively preventing soil particles, mud or sundries from entering the inside of the barrel body 103 and the liquid outlet hole 105 from the outside to avoid blockage of the hole.

[0056] When the barrel body 103 is inserted to the predetermined depth, the operator pulls the holding rod 101 upward, and the breaking soil pipe body 115 moves upward. Since the lower end of the blocking ring 121 is provided with a bearing surface matched with the top end of the breaking soil pipe body 115, when the sliding sleeve 116 rises to a certain position, the outer boss thereof contacts the bearing surface and applies an upward thrust, thereby driving the blocking ring 121 to move upward synchronously. With the rising of the blocking ring 121, the part thereof shielding the liquid outlet hole 105 gradually separates, and the liquid outlet hole 105 is exposed in sequence, and finally completely opened to form a liquid release channel. At this time, the pesticide spraying assembly is started, and the pesticide liquid can enter the inside of the barrel body 103 through the pesticide spraying channel and be injected from the completely opened liquid outlet hole 105 to the surrounding soil at high pressure, realizing deep and uniform diffusion of the pesticide.

[0057] The position limiter 104 comprises a clamping ring 122, a threaded sleeve 123, a sliding block 124, a rotating rod 125 and a handle 126. The clamping ring 122 is rotationally arranged on the holding rod 101. The threaded sleeve 123 is fixed below the clamping ring 122. The sliding block 124 is slidingly arranged on one side of the threaded sleeve 123. The rotating rod 125 is rotationally arranged on the sliding block 124. The handle 126 is connected with the rotating rod 125.

[0058] Specifically, the clamping ring 122 is rotationally arranged on the outer periphery of the holding rod 101 through a bearing or rotating shaft structure and can freely rotate around the holding rod 101, but the axial position is fixed. The clamping ring 122 serves as the installation base of the entire position limiter 104, and its stability directly affects the transmission accuracy.

[0059] The threaded sleeve 123 is fixed below the clamping ring 122 and rotates synchronously with the clamping ring 122. The threaded sleeve 123 is internally provided with internal threads which are engaged with the external threads on the outer wall of the barrel body 103 of the insertion barrel. In the initial state, the threaded sleeve 123 is locked.

[0060] To facilitate the operator to force and control the rotation direction, the application sets the operating arm mechanism composed of the sliding block 124, the rotating rod 125 and the handle 126. The sliding block 124 is slidingly arranged on the guide groove or slide rail of the outer wall of one side of the threaded sleeve 123, and can slide along the axial direction of the threaded sleeve 123. The rotating rod 125 is rotatably arranged on the sliding block 124 through a pin shaft or a hinged structure, one end of which is connected with the sliding block 124, and the other end is connected with the handle 126.

[0061] The handle 126 is a long rod-shaped hand-held component, and the surface is provided with anti-skid lines to facilitate holding. When in use, the operator holds the handle 126 and pulls it outwards, so that the sliding block 124 moves to the outlet position, at this time, the rotating rod 125 can be rotated, and the handle 126 is extended, so that the threaded sleeve 123 can be conveniently rotated through the handle 126.

[0062] The pesticide spraying assembly comprises a pesticide sprayer 106, a connecting head 107, a connecting pipe 108 and a pesticide tank 109. The connecting head 107 is in communication with the pesticide spraying channel, the connecting pipe 108 is connected with the connecting head 107, the pesticide sprayer 106 is in communication with the connecting pipe 108, and the pesticide tank 109 is in communication with the connecting pipe 108.

[0063] The connecting head 107 is arranged at the top of the holding cylinder, is fixedly connected with the inlet end of the pesticide spraying channel at the upper end of the holding rod 101, and realizes sealed communication through threads, buckles or quick-connection interfaces. The connecting head 107 is usually made of corrosion-resistant engineering plastics (such as polypropylene, POM) or stainless steel, and is internally provided with a tapered flow guide channel to reduce the flow resistance of the pesticide liquid. To prevent leakage under high pressure, the connecting head 107 is provided with a rubber sealing ring 120 or an O-ring at the interface with the pesticide spraying channel, so as to ensure that the system still maintains good air tightness and liquid tightness when working under high pressure. In some embodiments, the connecting head 107 can also integrate a one-way valve or a stop valve for controlling the flow direction of the pesticide liquid or preventing backflow when the pesticide tank 109 is replaced.

[0064] The connecting pipe 108 is a flexible pressure-resistant hose, one end of which is sealingly connected with the connecting head 107, and the other end is in communication with the pesticide sprayer 106 and the pesticide tank 109 respectively, forming the main channel for the delivery of pesticide liquid. The connecting pipe 108 adopts a multi-layer composite structure, the inner layer is made of chemically inert material (such as polytetrafluoroethylene PTFE) to prevent corrosion of the pesticide liquid, the middle layer is a high-strength woven fiber or steel wire reinforced layer to improve the pressure resistance, and can withstand a working pressure of 0.3-1.5 MPa, and the outer layer is a wear-resistant and anti-aging rubber or polyurethane sheath to adapt to complex outdoor environments. The length of the connecting pipe 108 is moderate (usually 1-3 meters), which not only ensures the flexibility of operation, but also avoids excessive length leading to pressure loss. The pipe body can be provided with a flow regulating valve or a pressure gauge interface to facilitate real-time monitoring of the pesticide application state.

[0065] The pesticide applicator 106 is a pesticide pressurizing device, which is the power source of the entire pesticide application assembly. It can be selected from various forms such as a manual plunger pump, a manual air pressure sprayer, an electric diaphragm pump, or a small high-pressure pump. When the manual pesticide applicator 106 is used, the operator press the handle back and forth or shakes the rocker to generate positive pressure in the pump cavity, so that the pesticide is sucked from the pesticide tank 109 and pressurized to be pushed to the connecting pipe 108. When the electric pesticide applicator 106 is used, a built-in battery drives a micro motor to drive the pump body to work, realizing continuous and stable high-pressure injection, significantly reducing labor intensity and improving work efficiency. The outlet of the pesticide applicator 106 is provided with a one-way valve to prevent backflow of the pesticide, and can be equipped with a pressure adjusting knob to adjust the pesticide injection pressure according to the soil compactness and the depth of the ant nest, realizing various pesticide application modes such as “low-pressure penetration” or “high-pressure impact”.

[0066] The pesticide tank 109 is a pesticide storage container, which is detachably installed in the connecting pipe 108, and is usually located at the liquid inlet end of the pesticide applicator 106 or is connected in parallel with the connecting pipe 108. The pesticide tank 109 is made of transparent or semi-transparent high-density polyethylene (HDPE) or polycarbonate (PC) material, which facilitates observation of the internal pesticide remaining amount. The volume of the pesticide tank 109 can be designed to be 0.5L to 5L according to the work requirements, which meets the pesticide application requirements of ant nests of different sizes. The pesticide tank 109 is provided with a filling port with a sealing cover at the top, which facilitates rapid filling of the pesticide; and is provided with a liquid outlet at the bottom, which is connected with the connecting pipe 108 through a hose. In order to prevent the pesticide from precipitating or stratifying, a micro stirring device or a magnetic stirring rod can be arranged in the pesticide tank 109 in some embodiments. In addition, the pesticide tank 109 can be equipped with an air balance pipe or a breather valve to ensure that the air pressure in the tank is stable during the output of the pesticide, so as to avoid poor liquid output caused by negative pressure.

[0067] In the actual work process, the operator first pours the ant-killing pesticide configured into the pesticide tank 109, and tightens the sealing cover; then starts the pesticide applicator 106, and uses negative pressure to suck the pesticide from the pesticide tank 109 through the connecting pipe 108 and the connecting head 107 into the pesticide application channel, and finally into the inside of the inserted cylinder. When the cylinder body 103 is inserted into the ant nest area and completes stable anchoring, the pressure is continued to be applied, and the pesticide is sprayed radially from the multiple liquid outlets 105 of the side wall of the cylinder body 103 to the surrounding soil under the action of pressure, overcoming the blockage of the blocking ring 121 or the sealing structure, rapidly penetrating into the ant path, nest chamber and core area where the queen ant is located, and realizing comprehensive coverage and deep killing.

Those skilled in the art can understand that all or part of the above-mentioned embodiments can be implemented, and equivalent changes made according to the claims of the present application still belong to the scope covered by the present application.
