Description

Drip irrigation head for farmland drip irrigation

technical field

The utility model relates to a drip irrigation tool, in particular to a drip irrigation head for farmland drip irrigation.

Background technique

With the advancement of science and technology, modern agricultural production technology is also developing rapidly. For example, drip irrigation technology has been popularized in terms of drought resistance and water saving, which has ensured the output of food, fruits and vegetables, and its benefits are huge. The existing dripper technology uses the main line to divert water to A number of branch roads are divided into the field at the edge of the field, and then the branch pipes are dripped on the soil next to the seedlings through the deceleration flow channel. This method has a huge water-saving advantage compared with flood irrigation and sprinkler irrigation, but drip irrigation is generally used in the field. In relatively dry weather, part of the water will still evaporate when it falls to the surface, and the soil where it drips will also agglomerate, causing soil compaction and reducing the air permeability of the soil. This drip irrigation method still needs to be improved.

Utility model content

In order to reduce the amount of evaporation and avoid compaction of the soil surface, the utility model provides a drip irrigation head used for drip irrigation in farmland

The technical solution adopted by the utility model is: a drip irrigation head for farmland drip irrigation, which is characterized in that it includes a ground cannula, a hose and a joint. The lower part of the ground cannula is a tapered tube with a vertical axis. In the seepage hole, the upper part of the tapered pipe is connected with an axis-level water inlet pipe, the water inlet pipe is connected with a hose, the hose is connected with a joint, and the joint is connected with a branch pipeline.

The seepage hole is a circular hole, and the axis of the circular hole forms an angle of 45 degrees with the side axis of the tapered pipe.

The seepage hole is a transverse cut, and the cut is at an angle of 45 degrees to the side axis of the tapered pipe.

The tapered pipe is covered with a filter screen.

The flexible pipe is a rubber tube, and a clip is arranged outside the rubber tube.

The inside of the joint is provided with a back-and-forth zigzag deceleration channel.

The utility model implements drip irrigation by inserting a tapered tube into the soil near the seedlings, which can reduce evaporation and avoid soil compaction.

Description of drawings

Fig. 1 is a structural schematic diagram of an embodiment of the utility model.

Label names in the figure: 1 hose; 2 joint; 3 tapered pipe; 4 water seepage hole; 5 water inlet pipe; 6 branch pipeline.

Detailed ways

The embodiment of the utility model is shown in Figure 1. The drip irrigation for farmland is provided with a ground intubation tube, a hose 1 and a joint 2. The lower part of the ground intubation tube is a tapered tube 3 with a vertical axis. The side wall of the tapered tube 3 is provided with Water seepage hole 4, water seepage hole 4 is a transverse incision, the incision and the side axis of the tapered pipe 3 are at an angle of 45 degrees to prevent blockage when inserted into the soil; the upper part of the tapered pipe 3 is connected with an axis-level water inlet pipe 5, and the water inlet pipe 5 is connected to a hose 1. The hose 1 is connected to the joint 2, and the joint 2 is connected to the branch pipeline 6. There is a back-and-forth zigzag deceleration channel inside the joint, and the large resistance can decompress and decelerate the water flow.

When the utility model is in use, the tapered tube is inserted into the soil near the seedlings to implement drip irrigation, which can reduce evaporation, avoid soil compaction, and has a simple structure and is easy to implement and popularize.

When the utility model is implemented, the water seepage hole 4 can also be a circular hole, and the axis of the circular hole is at an angle of 45 degrees with the side axis of the tapered pipe 3; Capillary action guides the water flow to diffuse in a large area and increases the penetration rate; the hose can be called a rubber tube, and a clip can be set outside the rubber tube. When a certain place is full and other parts still need to be filled, the clip can be used to clamp the rubber tube to intercept, so as to achieve balanced drip irrigation .
