Description

Technical Field

[0001] This application relates to the field of plant disease control technology, and more specifically, to underground slow-release inserts for the control of root diseases. Background Technology

[0002] Plant roots, as the foundation of growth, play a crucial role in the later growth and development of plants. During the seedling stage, plant roots often face root rot and plant death. To prevent root diseases, root drenching is commonly used for treatment. Slow-release pesticides can sterilize the soil around the seedling roots, effectively reducing the incidence of root diseases. Existing root drenching methods use pesticides that are encapsulated and adsorbed through special mechanisms, allowing pesticide molecules to be released slowly over a certain period. Traditional root drenching methods typically involve inserting a rod into the soil and then using a filling device to inject the slow-release pesticide along the rod, allowing it to flow into the deeper soil layers. This method only delivers the slow-release pesticide to the plant roots in one go, making it difficult to control and regulate pesticide input over a longer period. Consequently, after a certain period of use, if an increase in pesticide dosage is needed, the filling device must be used again, which is inconvenient. Therefore, we propose using a ground-based slow-release pesticide rod for root disease control. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a slow-release insert for controlling root diseases, solving the technical problems mentioned in the background art. The device consists of a T-shaped insert, a storage bottle, and an infusion assembly. It can be easily inserted into the underground root system of plants. By rotating the threaded rod, the cone head moves downwards along the insert, exposing the sponge column at the bottom of the insert through the strip guide groove. The slow-release pesticide in the storage bottle flows into the sponge column inside the insert through the infusion tube at a small flow rate, allowing the pesticide to slowly penetrate into the soil around the underground roots. This prolongs the action time of pesticide molecules, achieving efficient absorption of the slow-release pesticide components by the plant roots, thereby improving the control effect of root diseases. It is convenient to use and install, reduces ineffective use, and improves the utilization rate of pesticides.

[0005] 2. Technical Solution

[0006] This application provides a slow-release injection rod for root disease control, comprising: an injection rod and a cone head slidably installed at the bottom of the injection rod. A handle is fixedly provided at the upper end of the injection rod. A threaded rod is rotatably installed on the injection rod. The bottom end of the threaded rod is threadedly connected to the cone head. A sponge column is filled inside the bottom end of the injection rod, and the threaded rod moves through the sponge column. A positioning seat is fixedly positioned at the upper end of the injection rod. A liquid storage bottle is detachably installed on the positioning seat. An infusion assembly is detachably connected between the liquid storage bottle and the injection rod.

[0007] The infusion assembly includes an infusion tube, both ends of which are rotatably fitted with nut connectors for threaded connection to the grounding rod and the storage bottle, respectively. An air tube is fixedly sleeved on the infusion tube, and a spherical flow regulating valve is rotatably installed on the infusion tube.

[0008] By adopting the above technical solution, a T-shaped underground planting pole structure is formed, consisting of a planting pole, a cone head, a threaded rod, and a handle. By holding the handle, the cone head can be inserted into the underground root system of the plant. Rotating the threaded rod causes the cone head to continue downwards, exposing the sponge column at the bottom of the planting pole. A storage bottle pre-filled with a slow-release pesticide for plant disease control is connected to the bottom of the planting pole via an infusion tube. The slow-release pesticide in the storage bottle is then delivered to the sponge column inside the planting pole via the infusion tube. The flow rate can be adjusted by rotating the ball-shaped flow regulating valve on the infusion tube, allowing the pesticide to slowly penetrate into the soil around the underground roots. The pesticide molecules are slowly released into the underground soil over a certain period, effectively prolonging the pesticide's action time and achieving efficient absorption of the slow-release pesticide components by the plant roots. This achieves the goal of controlling plant root diseases, is easy to use and install, reduces ineffective use, and improves pesticide utilization.

[0009] Optionally, a first connector is fixedly sleeved at the bottom end of the insertion rod, and the first connector is threadedly sleeved with the nut connector at the bottom end of the infusion tube.

[0010] By adopting the above technical solution, the first connector is set as a threaded connector structure, which can be threadedly connected to the nut connector at the bottom of the infusion tube, making installation and processing convenient.

[0011] Optionally, two strip-shaped guide grooves are provided at the bottom end of the grounding rod. The strip-shaped guide grooves are connected to the inner cavity of the grounding rod. Two guide bars are fixedly provided on the inner wall of the cone head. The guide bars are slidably installed along the strip-shaped guide grooves.

[0012] By adopting the above technical solution, an inner cavity is set inside the ground-inserting rod, and the diameter of the inner cavity is set to be larger than the outer diameter of the threaded rod. This allows the medicine delivered by the infusion tube to the inner cavity of the ground-inserting rod to flow smoothly onto the sponge column. When the cone head slides down along the strip guide groove through the guide bar, the strip guide groove is connected to the inner cavity of the ground-inserting rod. Thus, after the sponge column absorbs the medicine, it will seep into the underground soil through the strip guide groove.

[0013] Optionally, a second connector is fixedly sleeved at the bottom of the liquid storage bottle, and the second connector is threadedly sleeved with the nut connector at the upper end of the infusion tube. A bottle cap is threadedly installed at the upper end of the liquid storage bottle.

[0014] By adopting the above technical solution, the second connector at the bottom of the liquid storage bottle is a threaded connector, which can be threaded into the nut connector at the top of the infusion tube for easy disassembly and assembly. In addition, the liquid storage bottle is threaded with a cap for easy addition of slow-release drugs.

[0015] Optionally, the positioning seat includes a horizontal block and two clamps. The horizontal block is fixed between the clamps, and the clamps are respectively limited by bolts and sleeved on the outside of the liquid storage bottle and the grounding rod.

[0016] By adopting the above technical solution, the two clamps connected by the horizontal block are used to limit and fix the installation of the liquid storage bottle and the grounding rod, so that the bottom of the grounding rod can be limited after being deeply inserted into the ground, while the liquid storage bottle is fixed and installed on the grounding rod by the positioning seat.

[0017] Optionally, a mounting hole is provided in the middle of the horizontal block, and the air pipe passes through the mounting hole of the horizontal block.

[0018] By adopting the above technical solution, the air pipe is installed through the mounting hole of the horizontal block. By setting the air pipe, the air flow and pressure balance in the infusion tube can be ensured during the delivery of medicine, preventing the generation of air bubbles in the medicine and affecting the delivery flow rate of the medicine. This allows the medicine in the storage bottle to be delivered smoothly and at a low flow rate through the infusion tube.

By rotating the threaded rod, the cone head moves down along the insert rod, exposing the sponge column at the bottom of the insert rod through the strip guide groove. The slow-release agent in the storage bottle flows into the sponge column in the insert rod at a small flow rate through the infusion tube, realizing the slow penetration of the agent into the soil around the underground root system, prolonging the action time of pesticide molecules, achieving the purpose of efficient absorption of slow-release agent components by plant roots, thereby improving the control effect of root diseases, being easy to use and install, reducing ineffective use, and improving the utilization rate of pesticides.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 4 This application provides a slow-release underground medicine insert for root disease control, comprising: an insert rod 1 and a cone head 2 slidably installed at the bottom of the insert rod 1. A handle 12 is fixedly provided at the upper end of the insert rod 1. A threaded rod 3 is rotatably installed on the insert rod 1. The bottom end of the threaded rod 3 is threadedly connected to the cone head 2. A sponge column 7 is filled inside the bottom end of the insert rod 1, and the threaded rod 3 moves through the sponge column 7. A positioning seat 4 is fixedly positioned at the upper end of the insert rod 1. A liquid storage bottle 5 is detachably installed on the positioning seat 4. An infusion assembly 6 is detachably connected between the liquid storage bottle 5 and the insert rod 1.

[0028] The infusion assembly 6 includes an infusion tube 61, with nut connectors 62 rotatably mounted at both ends for threaded connection to the planting pole 1 and the storage bottle 5, respectively. An air tube 63 is fixedly sleeved on the infusion tube 61, and a ball-shaped flow regulating valve 64 is rotatably mounted on the infusion tube 61. The planting pole 1, cone 2, threaded rod 3, and handle 12 form a T-shaped underground planting pole structure. By holding the handle 12, the cone 2 can be inserted into the underground root system of the plant. By rotating the threaded rod 3, the cone 2 continues to descend, exposing the sponge column 7 at the bottom of the planting pole 1. The storage bottle 5 is pre-filled with a slow-release agent for plant disease control. The liquid bottle 5 is connected to the bottom of the planting pole 1 via the infusion tube 61, allowing the slow-release pesticide in the liquid bottle 5 to be delivered to the sponge column 7 inside the planting pole 1 via the infusion tube 61. By rotating the ball flow regulating valve 64 on the infusion tube 61, the delivery flow rate of the infusion tube 61 can be adjusted, thereby allowing the pesticide molecules to slowly penetrate into the soil around the underground roots in conjunction with the sponge column 7. The pesticide molecules are slowly released into the underground soil within a certain period of time, which can effectively prolong the action time of the pesticide and achieve the purpose of efficient absorption of the slow-release pesticide components by the plant roots. This achieves the control of plant root diseases, is easy to use and install, reduces ineffective use, and improves the utilization rate of pesticides.

[0029] Reference Figure 2 and Figure 3 A first connector 11 is fixedly sleeved at the bottom end of the insertion rod 1. The first connector 11 is threadedly sleeved with the nut connector 62 at the bottom end of the infusion tube 61. The first connector 11 is set as a threaded connector structure, which can be threadedly connected with the nut connector 62 at the bottom end of the infusion tube 61, which is convenient for installation.

[0030] Reference Figure 2 and Figure 4 Two strip-shaped guide grooves 13 are opened at the bottom of the ground-inserting rod 1. The strip-shaped guide grooves 13 are connected to the inner cavity of the ground-inserting rod 1. Two guide strips 21 are fixedly installed on the inner wall of the cone head 2. The guide strips 21 are slidably installed along the strip-shaped guide grooves 13. The ground-inserting rod 1 has an inner cavity, and the diameter of the inner cavity is larger than the outer diameter of the threaded rod 3, so that the medicine delivered by the infusion tube 61 to the inner cavity of the ground-inserting rod 1 can flow smoothly to the sponge column 7. When the cone head 2 slides down along the strip-shaped guide grooves 13 through the guide strips 21, the strip-shaped guide grooves 13 are connected to the inner cavity of the ground-inserting rod 1. Thus, after the sponge column 7 absorbs the medicine, it will seep into the underground soil through the strip-shaped guide grooves 13.

[0031] Reference Figure 2 and Figure 3The bottom of the storage bottle 5 is fixedly fitted with a second connector 52, which is threadedly connected to the nut connector 62 at the upper end of the infusion tube 61. A bottle cap 51 is threadedly installed at the upper end of the storage bottle 5. The second connector 52 at the bottom of the storage bottle 5 is a threaded connector, which can be threadedly connected to the nut connector 62 at the upper end of the infusion tube 61 for easy disassembly and assembly. The bottle cap 51 is threadedly installed on the storage bottle 5 to facilitate the addition of slow-release drugs to the storage bottle 5.

[0032] Reference Figure 1 and Figure 2 The positioning seat 4 includes a horizontal block 41 and two clamps 42. The horizontal block 41 is fixed between the clamps 42. The clamps 42 are respectively limited by bolts and sleeved on the outside of the liquid storage bottle 5 and the grounding rod 1. The two clamps 42 connected by the horizontal block 41 are used to limit and fix the liquid storage bottle 5 and the grounding rod 1, so that the bottom of the grounding rod 1 can be limited after being deeply inserted into the ground, while the liquid storage bottle 5 is limited and installed on the grounding rod 1 by the positioning seat 4.

[0033] Reference Figure 1 and Figure 2 A mounting hole is provided in the middle of the horizontal block 41, and an air pipe 63 passes through the mounting hole of the horizontal block 41. The air pipe 63 is provided to ensure the balance of air flow and pressure in the infusion tube 61 during the delivery of medicine, prevent the generation of air bubbles in the medicine, and affect the delivery flow rate of the medicine. This allows the medicine in the storage bottle 5 to be delivered smoothly and at a low flow rate using the infusion tube 61.

[0034] Working principle: This insertion device consists of a T-shaped structure comprising an insertion rod 1, a cone head 2, a threaded rod 3, and a handle 12. In use, the cone head 2 can be easily inserted into the ground by holding and pressing the handle 12. Once it reaches the vicinity of the plant roots, rotating the threaded rod 3 causes the cone head 2 to slide downwards along the guide groove 13 via the guide bar 21. The guide groove 13 is connected to the inner cavity of the insertion rod 1, allowing the sponge column 7 to absorb the pesticide and seep into the soil through the guide groove 13. The storage bottle 5 is pre-filled with a slow-release pesticide for plant disease control. By rotating the spherical flow regulating valve 64, the slow-release agent in the storage bottle 5 is smoothly and at a low flow rate delivered through the infusion tube 61 to the bottom cavity of the ground-inserting rod 1 and flows onto the sponge column 7. After the sponge column 7 absorbs the agent, the agent will slowly penetrate into the soil around the underground roots. The pesticide molecules are slowly released into the underground soil within a certain period of time, which can effectively prolong the action time of the pesticide and achieve the purpose of efficient absorption of the slow-release agent components by the plant roots. This achieves the control of plant root diseases, is easy to use and install, reduces ineffective use, and improves the utilization rate of pesticides.
