Title:
DEVICE FOR AGRICULTURAL IRRIGATION
Document Type and Number:
WIPO Patent Application WO/2022/007068
Kind Code:
A1
Abstract:
Disclosed in the present invention is a device for agricultural irrigation, comprising a channel, a water guiding mechanism, and a first valve. The channel is provided on one side of farmland; the first valve and the water guiding mechanism are mounted to the channel; the first valve is used for draining water from the farmland into the channel; and the water guiding mechanism is used for feeding water from the channel into the farmland and automatically stopping the feeding when the water reaches a specified level. The utilization of the siphon effect to farmland irrigation and the use of the channel and water guiding mechanism in conjunction enable independent farmland irrigation. Moreover, the device is low in costs and convenient to use. Compared with methods using electromagnetic valves, the present invention achieves low costs and a wide application range. By using the principle of the lever, when closing, a sealing plug is fixed in a through hole by a greater force, and when opening, the sealing plug is pushed to open with a greater force. Soft and hard linkage levers work in conjunction with each other, so that the hard linkage lever can push the sealing plug to open, and the position of the sealing plug can be adaptively adjusted when the through hole is closed.
