[0002] Agricultural irrigation refers to an agricultural production activity that uses certain engineering facilities to provide necessary water sources for farmland, orchards, pastures, woodlands, etc. to meet the needs of normal crop growth. It is an indispensable and important link in agricultural production and is of great significance to increasing agricultural output and improving the agricultural ecological environment. The water source for agricultural irrigation can be groundwater, river water, lake water, rainwater, etc. Through different irrigation systems, such as channel irrigation, sprinkler irrigation, drip irrigation, infiltration irrigation, etc., the water source is transported to the farmland to provide the crops with the required moisture.

[0003] General agricultural irrigation methods are divided into manual irrigation and mechanical automatic irrigation. Both methods involve irrigating the land within a certain period of time without knowing whether the soil is short of water at this time. Blind irrigation not only wastes water resources but also easily leads to root rot of crops. Utility Model Content

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-3 The present embodiment provides a water-saving irrigation and fertilization device, including a support cylinder 1, a rotating seat 3 is installed on the top of the support cylinder 1, three connecting pipe openings 4 are installed at equal intervals on the outer ring surface of the rotating seat 3, one end of the connecting pipe opening 4 is connected to a spring 5, one end of the spring 5 is connected to a water spray pipe 6, and one end of the top of the water spray pipe 6 is installed with multiple nozzles 7, a U-shaped tube 8 is connected to the outer surface of the support cylinder 1, and electric control valves 9 are installed on the outer ring surfaces of two shunt pipes of the U-shaped tube 8, one side of the electric control valve 9 is connected to a wire 10, one end of the wire 10 is connected to a controller 11, and one side of the controller 11 is connected to two humidity sensors 12 through signal lines, and the humidity sensor 12 and the electric control valve 9 are all controlled by the controller 11, one end of the two shunt pipes of the U-tube 8 is connected to the water supply pipe and the fertilizer supply pipe respectively, and the humidity sensor 12 is inserted into the soil. When the humidity sensor 12 detects that the soil humidity is lower than the growth humidity requirement of the crops, the controller 11 controls the shunt pipe electric control valve 9 connected to the water supply pipe to open. At this time, the water supply pipe injects water into the support tube 1 through the U-tube 8, and enters the rotating seat 3 through the support tube 1, and finally sprays it out through the nozzle 7 on the water spray pipe 6 to irrigate the soil. By monitoring the soil humidity, the land irrigation time is reasonably selected, thereby effectively avoiding the problem of water waste caused by blind irrigation, and playing a role in water saving.

[0024] In this embodiment, if Figure 1 and Figure 2As shown, the bottom of the support tube 1 is fixedly connected with a ground plug 2, the interior of the support tube 1 is communicated with the interior of the rotating seat 3, the top of the rotating seat 3 can rotate, one end of the water spray pipe 6 is provided with a connecting pipe connected to the connecting pipe mouth 4, and the spring 5 is sleeved on the outer ring surface of the connecting pipe. After the water flow enters the rotating seat 3, the water flow is transported to the water spray pipe 6 through the three connecting pipe mouths 4 into the connecting pipe, thereby forming a pressure difference, causing the top of the rotating seat 3 to rotate, thereby increasing the irrigation range.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, one end of the water spray pipe 6 is sleeved on the outer annular surface of the connecting pipe, and a sealing gasket is provided at one end of the connecting pipe. When the water spray pipe 6 slides to one end of the connecting pipe, the sealing gasket is squeezed with the inner edge plate of the water spray pipe 6 to form a sealing fit. In the initial state, the spring 5 pulls the water spray pipe 6 to slide on the connecting pipe toward the connecting pipe port 4. After water is supplied to the inside of the water spray pipe 6, the water spray pipe 6 extends, and after the water supply stops, the water spray pipe 6 retracts, thereby reducing the space occupancy rate of the water spray pipe 6 without affecting the irrigation range of the water spray pipe 6.

[0026] In this embodiment, if Figure 1 As shown, only one of the electric control valves 9 on the two shunt pipes on the U-shaped pipe 8 can be opened at a time, but after one electric control valve 9 is opened, the other electric control valve 9 is in a closed state, thereby preventing the irrigation water and fertilizer from mixing together and diluting the concentration of the fertilizer.

[0027] In this embodiment, if Figure 1 and Figure 3 As shown, one end of the shunt pipe connected to the fertilizer supply pipe on the U-shaped tube 8 is connected to a filter cartridge 13, and the other end of the filter cartridge 13 is connected to the fertilizer supply pipe, and clamps 14 are symmetrically installed on both sides of the inside of the filter cartridge 13, and a filter screen 15 is slidably installed inside the filter cartridge 13 between the two clamps 14, and a threaded connection cover is provided on the top of the filter cartridge 13. After the fertilizer passes through the shunt pipe and enters the filter cartridge 13, the undissolved solid blocks in the fertilizer are blocked by the filter screen 15 to prevent it from entering the pipeline behind and causing pipeline blockage. At the same time, the filter screen 15 can be removed by removing the threaded connection cover of the filter cartridge 13 and then pulling out the filter screen 15 for cleaning, thereby effectively preventing the pipeline blockage problem caused by the complete dissolution of the fertilizer during the fertilization process.

[0028] Working principle: When the agricultural irrigation and fertilization device is in use, firstly, the two shunt pipes of the U-shaped tube 8 are connected to the water supply pipe and the fertilizer supply pipe respectively, and the humidity sensor 12 is inserted into the soil. When the humidity sensor 12 detects that the soil humidity is lower than the growth humidity requirement of the crops, the controller 11 controls the electric control valve 9 of the shunt pipe connected to the water supply pipe to open. At this time, the water supply pipe injects water into the support tube 1 through the U-shaped tube 8, and enters the rotating seat 3 through the support tube 1. After the water flows into the rotating seat 3, it is transported to the water spray pipe 6 through the three connecting pipe openings 4, thereby forming a pressure difference, so that the top of the rotating seat 3 rotates , and finally sprayed out through the nozzle 7 on the water spray pipe 6 to irrigate the soil. By monitoring the soil moisture, the time for land irrigation is reasonably selected, thereby effectively avoiding the problem of water waste caused by blind irrigation, playing a role in water saving. When fertilizing, after the fertilizer enters the filter cartridge 13 through the shunt pipe, the undissolved solid blocks in the fertilizer are blocked by the filter screen 15 to prevent it from entering the subsequent pipeline and causing pipeline blockage. At the same time, the filter screen 15 can be removed by disassembling the threaded connection cover of the filter cartridge 13 and then pulling out the filter screen 15 for cleaning, thereby effectively preventing the pipeline blockage caused by the complete dissolution of the fertilizer during the fertilization process.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
