A continuous water pump for agricultural irrigation

Abstract

The invention relates to the field of hand cranking water suction pumps in daily life, in particular to a continuous water suction pump used for agricultural irrigation. The continuous water suction pump is mainly composed of piston pumps, a water inlet branched pipe and a water drawing pipe and is further composed of a water draining branched pipe and a water draining main pipe. Each piston pump comprises a cylinder barrel and a piston assembly matched with the cylinder barrel; a water draining opening and a water inlet are formed in the lower end of the wall of the cylinder barrel, the water inlet is communicated with the water drawing pipe through the water inlet branched pipe, the water draining opening is communicated with the water draining main pipe through the water draining branched pipe, the water inlet branched pipe and the water draining branched pipe are each provided with a one-way valve, and pumped water by the water suction pump cannot flow back. The pump further comprises a lever mechanism, a fixed block mechanism and an eccentric wheel mechanism; the lever mechanism is mounted on the piston pumps, the fixed block mechanism is connected with the lever mechanism, and the eccentric wheel mechanism is connected with the fixed block mechanism and mounted on the piston pumps. The continuous water suction pump is reasonable in structure, due to the arrangement of the lever mechanism, the eccentric wheel mechanism and the fixed block mechanism, the water sucking effect of the water suction pump is ensured, the structure is simple, operation is easy and convenient, and water sucking action can be achieved in a high-efficiency manner.

Description

technical field [0001] The invention relates to the technical field of hand water pumps in daily life, in particular to a continuous water pump used for agricultural irrigation. Background technique [0002] Water is the source of life, we use it every day in our daily life. At present, most cities and towns in our country have tap water supply, so there is no need to worry about running out of water. However, many rural and remote areas in our country do not have tap water. Most of them use well water or pumps to draw water. Some relatively well-off people have purchased electric water pumps to pump water. Pay the electricity fee for the later use, and the water pump cannot be used in areas without electricity. Therefore, most remote areas or poor areas still use simple water pumps. However, due to the intermittent water discharge of ordinary hand pumps, not only the water discharge rate is low, but also the water can only flow below the water outlet of the pump. When th...

Problems solved by technology

However, due to the intermittent water discharge of ordinary hand pumps, not only the water discharge rate is low, but also the water can only flow below the water outlet of the water pump. When the water pipe is lifted higher than the water outlet of the water pump, the water cannot be discharged, which indirectly leads to this A type of water pump cannot be used in sites with complex terrain,
