Farmland irrigation device

Abstract

The invention discloses a farmland irrigation device. The farmland irrigation device comprises a main pipe communicated with a water storage pond, and a water pump motor, a filtering device and a branch pipe are sequentially arranged on the main pipe. One or above current stabilizers at intervals are arranged on the pipe wall of the branch pipe, a drop irrigation device is communicated to each current stabilizer, and a sterilization device is also arranged on the main pipe and located at the output end of the filtering device; the drop irrigation devices comprise irrigation delivering pipes, irrigation pipes, irrigation pipe control panels, control-panel stretchable springs, irrigation adjusting pipes, irrigation adjusting blocks and irrigation driving rings, and the irrigation adjusting pipes are arranged on the outer sides of the irrigation pipes. By means of the farmland irrigation device, it can be guaranteed that work is normal, and the unstable water pressure is avoided, and the flow quantity of drop irrigation can be controlled, and biting of mice is prevented.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a farmland irrigation equipment. Background technique [0002] In China, the use of oranges and potter's wheels to irrigate farmland has a long history. From the 2nd to the 1st century BC, there were rollovers, that is, keel waterwheels. Bi Lan in the Eastern Han Dynasty and Ma Jun in the Wei Dynasty of the Three Kingdoms both improved the rollovers. In the "Wang Zhennongshu" of the Yuan Dynasty, there are also tools such as drum carts and high-drum carts that use natural water to automatically lift water, indicating that these tools have been widely used in the early 14th century AD. Tangerines were also used in Egypt and India in ancient times. In the 5th century, the Portuguese made a wooden two-blade pump, which is the prototype of a modern centrifugal pump. At the beginning of the 18th century, France made the first volute vane pump. European and American countries made multist...

AI Technical Summary

Problems solved by technology

[0005] The existing drip irrigation equipment has the following disadvantages: 1. After the drip irrigation equipment has been used for a period of time, a large amount of algae will grow in the passage holes of the main pipe and the current stabilizer, and the algae will block the main pipe and the current stabilizer, causing the drip irrigation equipment to fail to work normally; 2. The pressure in the main pipe cannot be controlled. If the water pressure is too high or too low, it will cause damage to the drip irrigation equipment and reduce the service life of the drip irrigation equipment; 3. Ordinary drip irrigation is quantitative drip irrigation, and the drip irrigation flow cannot be changed, and the plant cannot be guaranteed. The requirements of plants for water; 4. The drip irrigation pipe is often damaged by rat bites, which affects its normal use
