Small agricultural water lifting device capable of realizing sealed type two-way water absorption and two-way continuous water supply

Abstract

The invention relates to a small agricultural water lifting device capable of realizing sealed type two-way water absorption and two-way continuous water supply. The small agricultural water lifting device comprises a well body, wherein a piston for blocking the cross section of the well body is arranged in the well body and is connected with a piston rod; a hand-pressing rod is connected to the upper end of the piston rod through an arc-shaped connecting rod and extends to the outer part of the well body; an upper water inlet, a lower water inlet, an upper water outlet and a lower water outlet are formed in the side wall of the well body; one-way water inlet valves are arranged in the upper water inlet and the lower water inlet; one-way water outlet valves are arranged in the upper wateroutlet and the lower water outlet; the upper water inlet and the lower water inlet communicate through a water inlet pipe; the water inlet pipe is connected with an external water inlet pipe; the tailend of the external water inlet pipe is arranged in a water source; the upper water outlet and the lower water outlet communicate through a water outlet pipe; and the water outlet pipe is connected with an external water outlet pipe. According to the small agricultural water lifting device of the invention, double water absorption and double water drainage functions are realized, and meanwhile, the continuity of water supply is further ensured. The small agricultural water lifting device of the invention is large in water yield, high in working efficiency, good in sealing performance, capableof meeting the multi-target water intaking demand around a water source region so as to enlarge an irrigation space, convenient to operate, and easy to disassemble and carry.

Description

technical field [0001] The invention relates to a small-scale agricultural water-lifting device with closed two-way water absorption and two-way continuous water supply, belonging to the technical field of agricultural water and soil engineering. Background technique [0002] At present, the commonly used agricultural irrigation and water lifting devices mostly use energy-powered machinery such as wind and electricity. This type of device is labor-saving and efficient, and has greatly promoted the development of agricultural production. However, in most impoverished areas in my country, especially in remote mountainous areas, due to the lack of field power resources and poor traffic conditions, diesel (gasoline) oil engines are generally large in size, inconvenient to transport, and high in cost, easily damaged, and repair and maintenance costs High, resulting in insufficient purchasing power of people in poverty-stricken areas, agricultural irrigation is difficult, and agric...

Problems solved by technology

However, in most impoverished areas in my country, especially in remote mountainous areas, due to the lack of field power resources and poor traffic conditions, diesel (gasoline) oil engines are generally large in size, inconvenient to transport, and high in cost, easily damaged, and repair and maintenance costs High, resulting in insufficient purchasing power of people in poverty-stricken areas, agricultural irrigation is difficult, and agricultural water can only be carried by people on their shoulders, or depend on the sky for food. Due to the lack of irrigation conditions, it is difficult to plant crops, orchards, etc., and the output rate of farmland is low.

In addition, the existing human-powered water-lifting devices are mostly used for groundwater intake. For areas where groundwater resources are not abundant or groundwater intake is difficult, water intake for irrigation is limited to a certain extent.
