Abstract

The utility model proposes an underground irrigator for farmland, which includes a main pipe, on which a plurality of thin tubes are vertically arranged, and the main pipe is a double-hole pipe, which is respectively used to transport irrigation liquid and hydraulic liquid; Layer casing, inside there is a water outlet pipe that is closed and connected up and down and can be stretched together with the multi-layer casing. There is a water outlet hole on the top side of the innermost casing. The tube is sealed; the tube for conveying hydraulic fluid in the main pipe is airtightly connected to the airtight casing of the thin tube, and the pipe for conveying irrigation liquid is in airtight communication with the outlet pipe of the thin tube. When the utility model is used for irrigation, the thin tube can be raised to an appropriate height, so that the mouth of the tube is irrigating the root system of the crops, saving water; meanwhile, the thin tube can be lowered for protection when plowing and turning the soil, which is convenient for use. In addition, the water outlet of the narrow tube is located on the side instead of the top surface, which can effectively prevent the water outlet from being blocked by mud when the thin tube moves up and down.

Description

An underground irrigator for farmland

technical field

The utility model belongs to the field of farmland irrigation, in particular to a farmland underground irrigator.

Background technique

At present, in order to save water when irrigating farmland, people have used surface irrigation pipes and underground irrigation pipes. However, surface irrigation pipelines consume a lot of water and are not suitable for irrigation of intensive crops such as rice and wheat; traditional underground irrigation pipelines are fixed underground and are easily damaged when plowing the fields. The way to remove the equipment is time-consuming and labor-intensive, and it is very inconvenient to use. The most important thing is that the root systems of various plants are deep or shallow, it is difficult to pour water directly on the root systems, and optimal irrigation cannot be achieved.

Utility model content

Aiming at the above problems, the utility model proposes an underground irrigator for farmland, which has a simple structure, not only can realize water-saving irrigation, but also the thin irrigation pipe can be stretched up and down, and the thin pipe can be lowered when plowing the field without turning the equipment It is very practical and convenient to disassemble.

The technical solution provided by the utility model is: an underground irrigator for farmland, including a main pipe, characterized in that: the main pipe is vertically provided with a plurality of thin tubes, and the main pipe is a double-hole pipe, which is used to transport irrigation liquid and water respectively. hydraulic fluid; the thin tube is a retractable multi-layer casing that is closed up and down, and there is a water outlet pipe that is closed and connected up and down that can be stretched together with the multi-layer casing. The side position of the water pipe below the water outlet hole is sealed with the innermost casing; the pipe for conveying hydraulic fluid in the main pipe is airtightly connected to the airtight casing of the thin pipe, and the pipe for conveying irrigation liquid is airtightly connected with the outlet pipe of the thin pipe.

The beneficial effects of the utility model are: the utility model is equipped with thin tubes that can be stretched up and down, and the thin tubes can be raised to an appropriate height when using the utility model for irrigation, so that the nozzles are irrigating the roots of the crops, thereby achieving the most water-saving Irrigation; at the same time, the thin tube can be lowered for protection when plowing and turning the soil, and the stem can be plowed without disassembling the equipment. In addition, the water outlet of the narrow tube is located on the side instead of the top surface, which can effectively prevent the water outlet from being blocked by mud when the thin tube moves up and down.

Fig. 1 is the overall structural arrangement drawing of the present utility model.

Fig. 2 is a schematic structural diagram of the main pipe in Fig. 1 .

Fig. 3 is a schematic diagram of the structure of the thin tube in Fig. 1 .

In the figure: 1. Thin tube, 2. Main pipe, 3. Water outlet hole, 4. Hydraulic liquid inlet, 5. Water outlet pipe, 6. Main pipe interface, 7. Irrigation liquid, 8. Hydraulic liquid.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Fig. 1, the utility model includes a main pipe, on which a plurality of thin tubes are vertically arranged, and the main pipe is connected with external irrigation equipment through a main pipe interface.

As shown in Figure 2, the main pipe is a double-hole pipe, which is used to transport irrigation liquid and hydraulic liquid respectively.

As shown in Figure 3, the thin tube is a scalable multi-layer casing that is closed up and down, and there is a water outlet pipe that is closed and connected up and down that can be stretched together with the multi-layer casing. The top side of the innermost casing has a water outlet hole. The side position of the water outlet pipe below the water outlet hole is sealed with the innermost casing; the pipe for conveying hydraulic fluid in the main pipe is airtightly connected to the airtight casing of the thin pipe, and the pipe for conveying irrigation liquid is airtightly communicated with the outlet pipe of the thin pipe.

The utility model is buried under the field, and used after connecting the main pipe interface with the external irrigation equipment. When plowing and turning the soil, the hydraulic fluid filled in the thin tube is pumped away through the hydraulic liquid inlet, and the thin tube is lowered for self-protection, and the stem can be plowed without disassembling the equipment; when irrigating, the hydraulic fluid in the main pipe is fed through the hydraulic liquid The mouth enters the thin tube, and the thin tube rises to an appropriate height, so that the water outlet is directly facing the root system of the crop, so as to achieve the most water-saving irrigation. In addition, the water outlet hole of the narrow tube is located on the side instead of the top surface, which can effectively prevent the water outlet from being blocked by mud when the thin tube moves up and down.
