Description

Technical Field

[0001] The utility model relates to the technical field of water and fertilizer irrigation, in particular to a water and fertilizer integrated drip irrigation device. Background Technique

[0002] When planting crops on a large scale, it is necessary to adjust the irrigation flow according to the water demand of the crops. However, for arid and semi-arid regions, different irrigation strategies need to be adopted to ensure the water demand standard of the crops. In order to reduce the waste of water resources and maintain the water demand conditions of the crops, drip irrigation is currently mostly used to carry out water retention drip irrigation measures for crops or crop seedlings. During the drip irrigation process, in addition to dripping water bodies on the crops, fertilizers can also be added to the water to form water and fertilizer, which can meet the nutritional needs of the crops while meeting the water demand conditions of the crops.

[0003] In the process of drip irrigation and drainage of the existing water and fertilizer integrated drip irrigation device, it completely relies on active pressurization structures such as lift pumps to achieve pressurized drip flow of the water body in the drip irrigation conduit. On the one hand, the adjustment range of the drip irrigation pressure is limited, and on the other hand, it is not conducive to saving energy. Therefore, we propose a water and fertilizer integrated drip irrigation device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water and fertilizer integrated drip irrigation device to solve the problems raised in the above background technique.

[0005] To achieve the above object, the utility model provides the following technical solutions: A water and fertilizer integrated drip irrigation device, including a support structure and a lift pump. The lift pump is electrically connected to an external power source. One side of the lift pump is connected with an external pipeline, and the external pipeline is connected to an external water and fertilizer supply source to introduce the water body or fertilizer in the water and fertilizer supply source into the lift pump. The top of the support structure is welded with a hollow main pipeline. A plurality of drip irrigation channels are connected to the side of the main pipeline. A plurality of drip holes are opened at the bottom of the drip irrigation channels. One end of the drip irrigation channel is detachably connected with an extension drip pipe through a joint. The extension drip pipe is a flexible pipe with a plurality of drip holes, which can extend the drip irrigation range. The top of the main pipeline is communicated with a non-powered liquid tank through an inverted cone connecting pipe. The liquid in the non-powered liquid tank generates hydraulic pressure on the liquid level of the inverted cone connecting pipe. The hydraulic pressure in the inverted cone connecting pipe is used to maintain the liquid pressure in the main pipeline, so as to cooperate with the lift pump to increase the upper and lower limits of the liquid pressure value of drip irrigation, improve the adaptability to the drip irrigation requirements of different crops, and is beneficial to expanding the types of crops for drip irrigation. The rainwater is filtered by a conical filter screen, and the rainwater entering the non-powered liquid tank can be filtered and collected for use, which is beneficial to water saving and energy saving. By setting a fixed ring detachably connected to the non-powered liquid tank, it is convenient to clean the surface of the conical filter screen. The top of the non-powered liquid tank is detachably connected with a rainwater filtering structure. The top of the lift pump is connected with a Z-shaped pipe through a water and fertilizer homogenizing component. One end of the Z-shaped pipe is welded through the main pipeline with a drainage pipe. The top of the Z-shaped pipe is communicated with a lift pipe. One end of the lift pipe is connected with a delivery pipe through a one-way valve. The delivery pipe can transport water body and water and fertilizer into the non-powered liquid tank to maintain the pressure of the liquid in the non-powered liquid tank on the inverted cone connecting pipe

[0006] As a further solution of the utility model: The support structure includes a positioning disk and a support column vertically fixed to the top of the positioning disk.

The homogenization tank is a hollow cylindrical cavity with a diameter not less than five times that of the first connecting pipe. The input end of the motor is electrically connected to an external power supply. The stirring rod stirs the water and fertilizer in the homogenization tank. A number of stirring blades are evenly distributed on the surface of the stirring rod, which can increase the contact area with the water and fertilizer, improve the stirring efficiency, make the nutrient substances included in the water and fertilizer for drip irrigation more evenly distributed, prevent the situation of uneven distribution of water and fertilizer.
