Description

Technical Field

[0001] The utility model relates to the technical field of nematode prevention and control, in particular to a liquid quantitative drip irrigation device for nematode prevention and control. Background Art

[0002] A type of pesticide 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 which live in the soil, and some parasitize in the body of plants. Nematodes are spread through soil or seeds, can damage the root system of plants, or invade the organs of the above-ground parts, affecting the growth and development of crops, and indirectly spread diseases caused by other microorganisms, causing great economic losses. The use of pesticides to control nematodes is an effective method widely used in modern agriculture. It is generally used for soil treatment or seed treatment. Nematicides are divided into two categories: volatile and non-volatile. The former has a fumigation effect, and the latter has a contact effect. They should generally have good lipophilicity and environmental stability, can diffuse in the soil in liquid or gaseous form, penetrate through the nematode epidermis to have a toxic effect, and most nematicides are highly toxic to humans and animals. Some varieties are harmful to crops, so special attention should be paid to safe use.

[0003] Most of the existing drip irrigation devices for nematode prevention cannot control the amount of drip irrigation. Since nematicides have certain toxicity, if the amount of drip irrigation cannot be reasonably controlled, the nematicides are likely to damage the surrounding soil environment and crops, thereby affecting plant yields and easily causing unnecessary economic losses. In addition, due to the different heights of crops and the different parts of the crops affected by nematode diseases, most drip irrigation devices cannot reasonably adjust the angle of the nozzles, thereby failing to achieve a suitable insecticidal effect, resulting in a waste of nematicides.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Example 1

[0037] Reference Figure 1-7, which is the first embodiment of the utility model, provides a liquid quantitative drip irrigation device for preventing and controlling nematodes, including a drip irrigation tube 1 and a plug-in assembly 2 arranged at the lower end of the drip irrigation tube 1, a pipe assembly 3 is arranged at the upper end of the drip irrigation tube 1, a motor 4 is arranged inside the drip irrigation tube 1, and a quantitative assembly 5 is connected to the output end of the motor 4, four symmetrical groups of slide grooves 6 are opened on the inner wall of the drip irrigation tube 1, and a second spring 7 is arranged inside the slide groove 6, a limit block 8 is inserted into the inner wall of the slide groove 6, and an adjustment assembly 9 is arranged on the outer wall of the drip irrigation tube 1;

[0038] The pipeline assembly 3 includes a sleeve 33 inserted into the upper end of the drip irrigation tube 1, and a cross tube 31 is inserted into the inner wall of the upper end of the sleeve 33;

[0039] The quantitative component 5 includes a rotating rod 51 arranged at the output end of the motor 4, and a first spring 52 is arranged at the upper end of the rotating rod 51, and a rotating disk 53 is arranged at the end of the first spring 52 away from the rotating rod 51, and a limiting groove 54 is arranged on the outer wall of the rotating disk 53, and a first through hole 55 is arranged on the outer wall of one side of the rotating disk 53, and a connecting disk 56 is arranged at the lower end of the rotating disk 53, and a second through hole 57 is arranged on the outer wall of one side of the connecting disk 56, and a fixed disk 58 is arranged at the lower end of the connecting disk 56, and three groups of third through holes 59 are evenly arranged on the outer wall of the fixed disk 58, and the front end of the rotating rod 51 is arranged in an inclined shape that matches the limiting block 8, and the limiting block 8 is arranged in a wedge shape. There are four groups of limit blocks 8, one of which is movably inserted in the limit groove 54 that matches the limit block 8, the fixed plate 58 is fixedly connected to the inner wall of the drip irrigation tube 1, the connecting plate 56 is fixedly connected to the rotating plate 53, the lower end surface of the rotating plate 53 is fixedly connected to the upper end surface of the fixed plate 58, the first through hole 55 and the second through hole 57 are of the same size, and the first through hole 55 and the second through hole 57 correspond to each other in the vertical direction. When one of the four groups of limit blocks 8 is located in the limit groove 54, one of the three groups of third through holes 59 and the centers of the first through hole 55 and the second through hole 57 are on the same vertical line, and the lower end surface of the rotating rod 51 does not contact the upper end surface of the rotating plate 53.

[0040] The insecticide enters the drip irrigation tube 1 from the cross tube 31 and the sleeve 33, and the motor 4 rotates slowly and uniformly. Before the inclined surface at the front end of the rotating rod 51 does not contact the limit block 8, the centers of the first through hole 55, the second through hole 57 and one of the third through holes 59 are on the same vertical line, and the insecticide flows out from the three through holes and enters one of the nozzles 93. Then, the nematicide is sprayed on the parts of the crops infected by nematodes through the nozzles 93. During the spraying process, the motor 4 continues to rotate slowly, and the motor 4 drives the rotating rod 51 to rotate. The rotating rod 51 stretches the first spring 52. Since the rotating rod 51 has not yet contacted one of the limit blocks 8 inserted in the limit groove 54, the turntable 53 cannot rotate under the elastic force of the first spring 52. However, when the motor 4 drives the rotating rod 51 to rotate to contact one of the limit blocks 8 inserted in the limit groove 54, the limit block 8 will receive the inclined surface at the front end of the rotating rod 51. When the limit block 8 leaves the limit slot 54, the rotating disk 53 rotates under the tensile force of the first spring 52, and the limit slot 54 also rotates accordingly. When the limit slot 54 touches another set of limit blocks 8, the limit block 8 is inserted into the limit slot 54 under the elastic force of the second spring 7. At this time, the rotating disk 53 cannot rotate, and the first through hole 55 and the second through hole 57 rotate to above another set of third through holes 59. Then the insecticide enters the nozzle 93 through the third through hole 59. According to the above operation, the rotating disk 53 can rotate periodically while the motor 4 rotates slowly and vulgarly, so that the three groups of nozzles 93 can spray periodically, and the spraying time and spraying dosage remain the same, which solves the problem that most existing drip irrigation devices cannot reasonably control the drip irrigation amount.

[0041] Example 2

[0042] Reference Figure 1-7 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that: the plug assembly 2 includes an insertion rod 21 arranged at the lower end of the drip irrigation tube 1, and a first sharp cone 22 is fixedly arranged at the lower end of the insertion rod 21, and three symmetrical groups of first adjustment rods 23 are hingedly connected to the outer wall of the insertion rod 21, and a second sharp cone 24 is hingedly connected to the lower end of the first adjustment rod 23;

[0043] Insert the rod 21 into the soil near the plants that need to be sprayed with insecticide. The first pointed cone 22 can make it easier for the rod 21 to be inserted into the soil. Then rotate the rod 21 to drive the drip irrigation tube 1 to rotate, and the nozzle 93 set on the outer wall of the drip irrigation tube 1 also rotates accordingly. Rotate the nozzle 93 to the position where insecticide spraying is required, then unfold the first adjusting rod 23, unfold the first adjusting rod 23, and insert the second pointed cone 24 into the soil, so that the entire device is placed on the soil more stably.

[0044] Example 3

[0045] Reference Figure 1-7 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the pipeline assembly 3 also includes a slider 32 arranged at the lower end of the cross pipe 31, the outer wall of the sleeve 33 is provided with a vertical groove 34 in the vertical direction and matched with the slider 32, and the outer wall of the sleeve 33 is provided with an annular groove 35 in the horizontal direction and matched with the slider 32, and the vertical groove 34 and the annular groove 35 are connected.

[0046] The adjusting assembly 9 includes a connecting pipe 91 disposed at the lower end of the third through hole 59, and one end of the connecting pipe 91 is connected to a hose 92, and one end of the hose 92 is connected to a nozzle 93.

[0047] The adjustment assembly 9 further includes connecting plates 94 disposed at both ends of the outer wall of the nozzle 93 , and the nozzle 93 and the connecting plates 94 are rotatably connected.

[0048] The adjustment assembly 9 further includes a second adjustment rod 95 disposed on the outer wall of the upper end of the nozzle 93 , and the second adjustment rod 95 and the outer wall of the upper end of the nozzle 93 are hinged.

[0049] The upper end of the second adjusting rod 95 is hingedly connected to a ball screw sleeve 96 , and a ball screw 97 is movably inserted in the middle end of the ball screw sleeve 96 , and the upper end of the ball screw 97 is rotatably connected to a connecting plate 98 , and the connecting plate 98 is fixedly connected to the upper end of the drip irrigation tube 1 .

[0050] The slider 32 is moved along the vertical groove 34, and the sleeve 33 is sleeved on the outer wall of the cross tube 31. Then the drip irrigation tube 1 is rotated so that the slider 32 slides into the annular groove 35 to complete the connection between the cross tube 31 and the sleeve 33. The cross tube 31 can be connected to other drip irrigation tubes 1. According to the length of the cross tube 31, the drip irrigation tube 1 can complete the full coverage of the plant. When the slider 32 slides into the annular groove 35, the cross tube 31 is not easy to fall off from the sleeve 33. When the angle of the nozzle 93 needs to be adjusted, The ball screw 97 is rotated to drive the ball screw sleeve 96 to move. Since the second adjusting rod 95 and the ball screw sleeve 96 are hinged, and the second adjusting rod 95 and the nozzle 93 are hinged, the second adjusting rod 95 is driven by the ball screw sleeve 96 to rotate a certain angle. Since the nozzle 93 and the connecting plate 94 are rotatably connected, the nozzle 93 is driven by the second adjusting rod 95 to rotate a certain angle, thereby changing the spraying range. Targeted spraying can be performed on the parts of the crops infected by nematodes, thereby achieving a better insecticide effect.

[0051] The remaining structures are the same as those of Example 1.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
