[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] Example 1

[0039] Reference Figure 1-8 , which is the first embodiment of the present invention, provides a plant root irrigation device for pest control, the plant root irrigation device for pest control, comprising a drill pipe 1, a foot pedal 2 is arranged above the drill pipe 1, a driving mechanism 6 is arranged above the foot pedal 2, a hand-held mechanism 4 is arranged above the driving mechanism 6, the driving mechanism 6 is used to drive the drill pipe 1 to move downward, an infusion mechanism 3 is arranged above the drill pipe 1, the infusion mechanism 3 comprises an axial tube 34, the axial tube 34 movably penetrates into the drill pipe 1, and the axial tube 34 is used to inject liquid into the drill pipe 1;

[0040] A conical head 11 is installed at the bottom end of the drill pipe 1. A plurality of injection holes 12 are opened in a circular array at the bottom of the drill pipe 1. An anti-blocking component 8 is arranged near the injection hole 12 in the drill pipe 1. The anti-blocking component 8 includes a conical block 86. The maximum outer diameter of the conical block 86 is equal to the inner diameter of the injection hole 12. The conical block 86 moves in the injection hole 12. A thin shaft rod 84 is installed at one end of the conical block 86 close to the inside of the drill pipe 1. The outer diameter of the thin shaft rod 84 is much smaller than the inner diameter of the injection hole 12. A cylindrical block 83 is installed at one end of the thin shaft rod 84 away from the conical block 86. The outer diameter of the cylindrical block 83 is equal to the inner diameter of the injection hole 12. A filter disc 85 is arranged between the cylindrical block 83 and the conical block 86. The inner diameter of the filter disc 85 is equal to the inner diameter of the injection hole 12. The filter disc 85 is sleeved on the outside of the thin shaft rod 84. There is a position control mechanism 7, which is used to drive the filter plate 85 to block the irrigation hole 12. At this time, the inside of the drill pipe 1 is connected with the outside of the drill pipe 1 through the filter plate 85. This state is the liquid discharge and root irrigation state, or the position control mechanism 7 is used to drive the cylindrical block 83 to move at the irrigation hole 12. At this time, the drill pipe 1 is not connected with the outside of the drill pipe 1, and the drill pipe 1 is ready to be pulled out. When the cylindrical block 83 moves in the irrigation hole 12 to the state where the filter plate 85 is pushed out of the irrigation hole 12, it is a clearing state, which is convenient for flushing the impurity soil at the filter plate 85, or the position control mechanism 7 is used to drive the conical block 86 to block the irrigation hole 12. At this time, the drill pipe 1 is inserted into the soil. At this time, the irrigation hole 12 does not discharge liquid, and before the maximum outer diameter of the conical block 86 leaves the irrigation hole 12, the filter plate 85 enters the irrigation hole 12.

[0041] The position control mechanism 7 includes a circular ring 75, a shaft cylinder 76 is concentrically mounted on the bottom end of the circular ring 75, a driving sleeve 77 is concentrically mounted on the bottom end of the shaft cylinder 76, and a plurality of T-shaped sliders 78 are mounted on the outer wall of the bottom of the driving sleeve 77 in a circular array. The liquid above the circular ring 75 passes through the middle of the shaft cylinder 76, passes through the middle of the driving sleeve 77, and falls around the plurality of injection holes 12, waiting for the liquid to be discharged. Figure 7 and Figure 8 As shown, the anti-blocking component 8 includes a right-angled trapezoidal slide 82, which is distributed in a ring array in the drill pipe 1. A slide groove 87 is provided on the inclined end surface of the right-angled trapezoidal slide 82. The T-shaped slider 78 is limited to slide in the slide groove 87. The right-angled side of the right-angled trapezoidal slide 82 is vertically and equidistantly installed with a plurality of cylindrical blocks 83. The ring 75 moves vertically to drive the thin shaft 84 to move in the injection hole 12. The sliding cooperation between the T-shaped slider 78 and the slide groove 87 is utilized to achieve the effect of horizontally pushing the right-angled trapezoidal slide 82, thereby controlling the use state of the injection hole 12.

[0042] like Figure 5As shown, a lifting rod 73 is installed at the top of the circular ring 75 near the inner wall of the drill pipe 1. The lifting rod 73 is movable and penetrates above the drill pipe 1. A clamping plate 74 is installed at the top of the lifting rod 73. A spring is arranged on the outer sleeve of the lifting rod 73. The two ends of the spring are respectively against the drill pipe 1 and the clamping plate 74. A support column 71 is installed at the top of the drill pipe 1. A plurality of horizontal plates 72 are vertically and equidistantly installed on one side of the support column 71 close to the lifting rod 73. The clamping plate 74 is rotated to be clamped between two adjacent horizontal plates 72 above and below to limit the position. The clamping plate 74 moves upward under the drive of the spring. When the circular ring 75 needs to be pushed downward, the clamping plate 74 is rotated to be clamped between adjacent horizontal plates 72 of corresponding height, so that the right-angled trapezoidal slide 82 can be positioned in a horizontal push-out state.

[0043] like Figure 7 and Figure 8 As shown, baffles 81 are respectively arranged on opposite sides of the bottom of the right-angle trapezoidal slide 82 , and the baffles 81 are fixedly connected to the inner wall of the bottom of the drill pipe 1 . The arrangement of the baffles 81 further limits the stable horizontal movement of the right-angle trapezoidal slide 82 .

[0044] In this embodiment, by arranging a position control mechanism 7 and an anti-blocking component 8 at the bottom of the drill pipe 1, when in the root irrigation state, the filter plate 85 is blocked at the irrigation hole 12, and soil impurities can be filtered out to enter the drill pipe 1, thereby ensuring the hygiene inside the drill pipe 1. By blocking the cylindrical block 83 at the irrigation hole 12, the filter plate 85 can be controlled to pass through the irrigation hole 12, thereby cleaning the irrigation hole 12 to ensure the effect of the anti-blocking component 8 for the next use, which is convenient to clean and improves the anti-blocking effect during the root irrigation process of plants.

[0045] Example 2

[0046] Reference Figure 1-5 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0047] A cylindrical box 33 is movably installed at the center position above the foot pedal 2, and the top of the axial tube 34 is concentrically connected to the cylindrical box 33. A movable cover is movably sleeved outside the cylindrical box 33, and the inner diameter of the movable cover is larger than the outer diameter of the cylindrical box 33. The top and bottom of the movable cover are movably connected to the cylindrical box 33 using sealed bearing sleeves respectively. The side wall of the cylindrical box 33 is provided with a circular hole connected to the movable cover, and the side wall of the movable cover is connected to a liquid inlet pipe 31, and a boosting pipe 32 is connected to one side of the liquid inlet pipe 31. Check valves are respectively installed outside the liquid inlet pipe 31 and the boosting pipe 32, and the check valves are used to control the liquid inlet pipe 31 to feed liquid into the cylindrical box 33. An electric control box 5 is installed above the driving mechanism 6, and a boosting pump is arranged in the electric control box 5. The boosting pipe 32 is connected to the output end of the boosting pump, and the check valve is used to control the boosting pump to boost the pressure in the boosting pipe 32.

[0048] In this embodiment, before root irrigation, liquid is injected into the drill pipe 1 through the liquid inlet pipe 31. After the drill pipe 1 is inserted into the ground, the booster pump is controlled to operate so that the booster pipe 32 increases the pressure in the drill pipe 1, thereby controlling the liquid in the drill pipe 1 to be discharged from the irrigation hole 12.

[0049] The remaining structures are the same as those of Example 1.

[0050] Example 3

[0051] Reference Figure 1 , Figure 3 and Figure 4 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that:

When the slide rod 43 is pulled upward to the top of the fixed sleeve 42, the slide rod 43 rotates and locks with the fixed sleeve 42. A hand-held handle 41 is arranged above the two fixed sleeves 42, and the top end of the slide rod 43 is movably connected to the hand-held handle 41. The electric control box 5 is installed between the two fixed sleeves 42.

[0053] In this embodiment, when the root irrigation device is not in use, the slide rod 43 is stored in the fixing sleeve 42, which can save the space occupied by the root irrigation device. When the root irrigation device is in use, the fixing sleeve 42 is pulled upward from the slide rod 43 to facilitate the operator to use and operate.

[0054] The remaining structure is the same as that of Example 2.

[0055] Example 4

[0056] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 , which is the fourth embodiment of the present invention, and this embodiment is different from the third embodiment in that:

[0057] The driving mechanism 6 includes a screw rod 61, the bottom end of which is concentrically connected to the cylindrical box 33. A fixed platform 65 is provided below the electric control box 5, and the fixed platform 65 is installed between the two fixed sleeves 42. The top end of the screw rod 61 is movably connected to the fixed platform 65, and a motor 64 for driving the screw rod 61 to rotate is installed above the fixed platform 65. A moving seat 63 is assembled outside the screw rod 61, and at least four groups of positioning rods 62 are installed on the side wall of the moving seat 63. The positioning rods 62 are used to limit the linear movement of the moving seat 63 on the screw rod 61, and the bottom end of the positioning rod 62 is fixedly connected to the foot pedal 2.

[0058] The electric control box 5 is provided with a power module and a control module, and the power module and the control module are used to control the operation of the motor 64 and the booster pump.

[0059] The bottom end of the axial tube 34 is provided with a plurality of stirring blades 35 in a circular array, and the lifting rod 73 is located outside the circumferential range of the stirring blades 35. When the screw 61 rotates, the cylindrical box 33 rotates together, and the axial tube 34 rotates together, and the stirring blades 35 stir the liquid in the drill pipe 1.

[0060] In this embodiment, when the drill pipe 1 is ready to be inserted into the ground, the conical head 11 is first positioned at the ground entry position, and then the foot pedal 2 is stepped on to ensure that the foot pedal 2 does not rotate. Then, the hand grip 41 is held by hand to turn on the motor 64. At this time, the screw 61 starts to rotate, the moving seat 63, the positioning rod 62 and the foot pedal 2 move downward, the foot pedal 2 is separated from the bottom of the fixed sleeve 42, and the foot pedal 2 pushes the top of the drill pipe 1 to move downward, so that the axial tube 34 and the drill pipe 1 axially slide together, and at the same time, the axial tube 34 stirs and mixes the liquid in the drill pipe 1 from bottom to top.
