Description

Technical Field

[0001] This utility model relates to the field of nematode control technology, specifically a liquid quantitative drip irrigation device for controlling nematodes. Background Technology

[0002] A class of pesticides used to control harmful nematodes. Nematodes belong to the class Nematoda of the phylum Nematoda. They are tiny and can be observed under a microscope. There are about 3,000 species of nematodes that are harmful to plants. Most of them live in the soil, while some parasitize plants. Nematodes are spread through the soil or seeds, damaging the root system of plants or invading the organs of the above-ground parts, affecting the growth and development of crops. They also indirectly spread diseases caused by other microorganisms, causing significant economic losses. Using pesticides to control nematodes is a widely adopted and effective method in modern agriculture. They are generally used for soil treatment or seed treatment. Nematicides are divided into two categories: volatile and non-volatile. The former has a fumigation effect, while the latter has a contact effect. Generally, they should have good lipophilicity and environmental stability, and be able to diffuse in the soil in liquid or gaseous form. They penetrate through the nematode epidermis to kill the nematodes. Most nematicides are highly toxic to humans and animals, and some varieties are phytotoxic to crops. Therefore, special attention should be paid to safe use.

[0003] In the prior art, Chinese utility model application CN202421285703.9 discloses a liquid quantitative drip irrigation device for nematode control. This device includes a drip irrigation cylinder and a connector assembly located at the lower end of the cylinder. A pipe assembly is located at the upper end of the cylinder. A motor is installed inside the cylinder, and its output is connected to a quantitative component. Four symmetrical sets of grooves are formed on the inner wall of the cylinder, and a second spring is installed inside each groove. Limiting blocks are inserted into the inner wall of each groove. An adjustment component is located on the outer wall of the cylinder. By incorporating the quantitative component, the amount of nematicide entering the nozzle can be periodically controlled, thus solving the problem that most existing drip irrigation devices cannot reasonably control the amount of irrigation, leading to soil damage and potential crop damage under continuous drip irrigation.

[0004] In the above technical solution, the spray angle of multiple adjustment components is adjustable. However, relying solely on the alignment of the through holes of the turntable and the connecting plate to control the flow rate is easily affected by the viscosity of the liquid, and the accuracy is difficult to guarantee. Therefore, we need to propose a liquid quantitative drip irrigation device for the control of nematodes. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a liquid quantitative drip irrigation device for controlling nematodes, comprising:

[0025] A pharmaceutical flow tube 1, and multiple sets of adjustment mechanisms 2 installed on one side of the pharmaceutical flow tube 1;

[0026] A quantitative drip irrigation mechanism 5 is set at the lower end of the regulating mechanism 2. One end of the quantitative drip irrigation mechanism 5 is equipped with a pressure mechanism 7 for dispensing the agent, and the other end of the quantitative drip irrigation mechanism 5 is equipped with a limiting mechanism 6 for adjusting the agent volume.

[0027] The quantitative drip irrigation mechanism 5 includes a metering cylinder 51 and an extended inner tube 52 inserted into one end of the metering cylinder 51. A sealing rubber plug 53 is fixedly connected to the outer side of the end of the extended inner tube 52 inside the metering cylinder 51. A nozzle 54 is provided at the end of the extended inner tube 52 outside the metering cylinder 51. A visible part 57 and a scale part 58 are provided on the outer side of the metering cylinder 51.

[0028] The limiting mechanism 6 includes a pull rod 61 and a guide beam 63. The pull rod 61 is fixedly connected to one end of the outer wall of the extended inner tube 52, and the guide beam 63 is fixedly connected to one end of the outer side of the measuring cylinder 51. The pull rod 61 is slidably disposed in a groove on the guide beam 63. One end of the pull rod 61 is threadedly connected to a second locking bolt 62. A second positioning hole 64 is provided in the groove of the guide beam 63 for the second locking bolt 62 to be inserted. The sliding of the pull rod 61 in the groove on the guide beam 63 ensures the stability of the extension and retraction of the extended inner tube 52. At the same time, the position of the pull rod 61 can be positioned by screwing the second locking bolt 62 into different second positioning holes 64, thereby facilitating the position restriction of the extended inner tube 52. Furthermore, under the action of the visible part 57 and the scale part 58, it is convenient to adjust the position of the extended inner tube 52 in the measuring cylinder 51, thereby facilitating the adjustment of the amount of titrated reagent.

[0029] The pressure mechanism 7 includes an electric push rod 71 disposed at one end opposite to the metering cylinder 51 and the extended inner tube 52. The telescopic end of the electric push rod 71 is located in the inner cavity of the metering cylinder 51 and is fixedly connected to a piston column 72. The position of the piston column 72 is moved by the electric push rod 71, thereby causing the piston column 72 to compress the agent in the metering cylinder 51 and the extended inner tube 52, so that the agent can be sprayed out through the nozzle 54. The piston column 72 is arranged in a stepped shape, and the cross section of the piston column 72 is arranged in a convex shape (not shown in the figure).

[0030] A connecting pipe 59 is provided on the outside of the measuring cylinder 51. A connecting hose 3 is provided at the lower end of the medicine flow square tube 1. A connecting valve 4 is provided at the lower end of the connecting hose 3, which is connected to the connecting pipe 59. The connecting valve 4 is used to easily connect the connecting hose 3 to the connecting pipe 59, so that the medicine in the medicine flow square tube 1 can enter the measuring cylinder 51 through the connecting pipe 59. After the medicine fills the measuring cylinder 51, the connecting valve 4 is closed.

[0031] The length of the piston column 72 is greater than the length of the connecting tube 59 to the end of the metering cylinder 51. The outer end of the metering cylinder 51 is fixedly connected to a second hinge seat 55 and a third hinge seat 56. The second hinge seat 55 and the third hinge seat 56 are both arranged on the same straight line. The outer diameter of the end of the piston column 72 is the same as the inner diameter of the extension inner tube 52, so that when the piston column 72 pushes out the medicine, the medicine in the extension inner tube 52 is pushed out, reducing the medicine residue in the extension inner tube 52 and improving the accuracy of the medicine titration.

[0032] The adjustment mechanism 2 includes a support rod 21. One side of the support rod 21 is fitted with multiple sets of positioning bolts 22 that are bolted to the pharmaceutical flow square tube 1. The lower end of the support rod 21 is rotatably mounted on the second hinge seat 55. The support rod 21 is conveniently installed by the multiple sets of positioning bolts 22, and the angle adjustment of the quantitative titration mechanism is convenient by rotating the support rod 21 and the second hinge seat 55.

[0033] A first hinge seat 23 is provided at the upper end of the support rod 21. A connecting square tube 24 is rotatably mounted on the first hinge seat 23. An insert rod 25 is inserted into the connecting square tube 24. One end of the insert rod 25 is rotatably mounted on a third hinge seat 56. A first locking bolt 26 is provided on one side of the connecting square tube 24. Multiple sets of first positioning holes 27 are opened on one side of the insert rod 25 for the first locking bolt 26 to be inserted. By screwing the first locking bolt 26 into the first positioning holes 27 at different positions on the insert rod 25, it is convenient to adjust the length of the insert rod 25, thereby facilitating the adjustment of the distance between the first hinge seat 23 and the third hinge seat 56, and further facilitating the adjustment of the tilt angle of the quantitative titration mechanism, so as to spray pesticides on vegetation at different heights and improve the control effect on nematodes.

[0034] During use, staff adjust the position of the extended inner tube 52 using the pull rod 61 according to the application requirements. The position of the extended inner tube 52 is precisely adjusted using the scale section 58 and the visible section 57. The stability of the extended inner tube 52 is ensured by screwing the second locking bolt 62 into the second positioning hole 64. The capacity difference between adjacent scales is 5ml. The connecting valve 4 is opened, allowing the pesticide in the square tube 1 to enter the metering cylinder 51 through the connecting pipe 59. At this time, the piston column 72 is in the initial position. The connecting valve 4 is equipped with a flow controller. When a quantitative flow rate is detected, the connecting valve 4 is closed, and the electric push rod 71 is activated to adjust the position of the piston column 72. This causes the piston column 72 to squeeze the pesticide in the metering cylinder 51 out of the nozzle 54, allowing the pesticide to be sprayed onto the vegetation and ensuring the control effect against nematodes.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
