Description

Technical Field

[0001] The utility model relates to the technical field of plant disease and insect pest control, in particular to a plant root irrigation device for disease and insect pest control. Background Art

[0002] Some rare plants need to be regularly disinfected for pests and diseases, one of which is to control pests and diseases at the base of the plants. Since the roots of plants are deep, applying drugs through traditional excavation is not only time-consuming and laborious, but also easy to damage the roots of plants. The existing plant root pest control is to inject drugs into the soil at the roots of plants through root irrigation equipment;

[0003] For example, patent application number CN202320795886.8 discloses a plant root irrigation device for pest control. The patent uses a motor, a threaded rod, a limit rod, a limit block, a lifting plate, a medicine irrigation tube, and a medicine irrigation hole to irrigate the roots, avoiding the manual insertion of the medicine irrigation tube into the soil, which consumes a lot of manpower, and the resistance of the soil makes it impossible to insert the device to the required depth, resulting in the failure of plant root irrigation and reduced effect of pest control.

[0004] In the actual use of this root irrigation method in the prior art, the injection holes are easily blocked by soil, which makes it difficult for the medicine solution to pass through the injection holes, resulting in root irrigation failure. Therefore, this root irrigation equipment is greatly affected by the soil during use. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a plant root irrigation device for pest control, so as to solve the problem that the plant root irrigation equipment in the prior art described in the background technology is easily blocked by soil.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a plant root irrigation device for pest control, comprising

[0007] Positioning barrel;

[0008] The pedal is annular and fixedly sleeved on the outer side wall of the opening end of the positioning barrel;

[0009] A threaded sleeve, fixedly connected to the top of the positioning barrel and passing through the top;

[0010] A positioning tube, the upper end of the outer circumferential wall of which is provided with an external thread, the positioning tube passes through the threaded sleeve and is connected to the threaded sleeve through the external thread;

[0011] A plurality of rotating handles fixedly connected to the positioning tube;

[0012] The pin is conical and movably arranged at the lower port of the positioning tube, and can block the lower port of the positioning tube.

[0013] Preferably, the insertion pin has a convex body, the inner wall of the positioning tube is fixedly connected with a positioning ring via a plurality of connecting rods, and the positioning ring is fixedly connected to the convex body via a spring.

[0014] Preferably: a guide rod which slides through the spring and the positioning ring is fixedly connected to the convex body.

[0015] Preferably, the insertion pin has an annular sealing surface, which surrounds the convex body and faces the lower surface of the positioning tube.

[0016] Preferably: a limiting ring is fixedly connected inside the positioning barrel, and the positioning tube slides through the limiting ring.

[0017] Preferably, the pedal is provided with a plurality of insertion holes which slide through the pedal, and the insertion holes are used for ground nails to pass through.

[0018] The beneficial effects of adopting the above technical solution are:

[0019] The positioning tube provided in the present application can be rotated to enable the positioning tube to move relative to the threaded sleeve, so that the positioning tube can move downward and enter the soil, and the insertion needle can reduce the resistance to entering the soil, and can also seal the lower end of the positioning tube. When the positioning tube enters the required depth, the positioning tube is rotated, and a gap will be generated between the insertion needle and the positioning tube. At this time, liquid medicine is poured into the positioning tube, and the liquid medicine will flow out from the gap between the positioning tube and the insertion needle.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4In the first embodiment, a plant root irrigation device for pest control includes:

[0027] Positioning barrel 10;

[0028] The pedal 20 is annular and fixedly sleeved on the outer side wall of the opening end of the positioning barrel 10;

[0029] The threaded sleeve 44 is fixedly connected to the top of the positioning barrel 10 and passes through the top;

[0030] The positioning tube 30 has an outer thread 31 on the upper end of the outer circumferential wall. The positioning tube 30 passes through the threaded sleeve 44 and is connected to the threaded sleeve 44 through the outer thread 31.

[0031] A plurality of rotating handles 32 are fixedly connected to the positioning tube 30;

[0032] The insertion pin 50 is conical and movably disposed at the lower port of the positioning tube 30 , and can block the lower port of the positioning tube 30 .

[0033] This embodiment is implemented as follows:

[0034] When the present application is in use, the pedal 20 is placed on the ground, and then the pedal 20 is stepped on with the foot. At this time, the positioning tube 30 is rotated by rotating the handle 32, so that the positioning tube 30 moves downward along the threaded sleeve 40. At this time, the lower ends of the pin 50 and the positioning tube 30 will gradually enter the soil. In this process, the pin 50 will always block the lower end of the positioning tube 30. Then, the positioning tube 30 is rotated to create a gap between the pin 50 and the positioning tube 30. Then, the medicine is poured into the positioning tube 30. At this time, the medicine will flow into the soil from the gap between the pin 50 and the positioning tube 30 along the positioning tube 30.

[0035] The advantages of the present application over the prior art are good root irrigation effect and less prone to clogging.

[0036] See also Figure 3 , 4 The pin 50 has a protrusion 51, and the inner wall of the positioning tube 30 is fixedly connected with a positioning ring 61 through a plurality of connecting rods 62, and the positioning ring 61 and the protrusion 51 are fixedly connected through a spring 60;

[0037] When the positioning tube 30 rotates, the positioning tube 30 moves upward. At this time, under the action of the spring 60, the pin 50 does not move, and a gap is generated between the pin 50 and the positioning tube 30. In the process of the positioning tube 30 entering the soil, the spring 60 is in a compressed state.

[0038] See also Figure 3 , 4 , a guide rod 63 is fixedly connected to the convex body 51 and slides through the spring 60 and the positioning ring 61;

[0039] The guide rod 63 increases the stability of the movement of the pin 50 relative to the positioning tube 61 .

[0040] See also Figure 3 , 4 The pin 50 has an annular sealing surface 52, which surrounds the convex body 51 and faces the lower surface of the positioning tube 30;

[0041] The sealing surface 52 can match the lower surface of the positioning tube 30, so that the sealing effect is improved and it is not easy to enter the soil.

[0042] See also Figure 3 The positioning barrel 10 is fixedly connected to a limiting ring 33, and the positioning tube 30 slides through the limiting ring 33;

[0043] The limiting ring 33 can increase the stability of the vertical movement of the positioning tube 30 .

[0044] See also Figure 1 The pedal 20 is provided with a plurality of insertion holes 21 that slide through the pedal 20 , and the insertion holes 21 are used for ground nails to pass through;

[0045] By passing the ground nail through the insertion hole 21 on the pedal 20, the pedal 20 can be conveniently fixed to the ground.

[0046] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
