Continuous water suction pump used 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-cranked water pumps in daily life, in particular to a continuous water pump for agricultural irrigation. Background technique [0002] Water is the source of life, and we use water every day in our daily lives. At present, most cities and towns in our country have tap water supply, so don't worry about running out of water. However, many rural and remote areas in my country do not have access to tap water. Most of them use well water or pumps to pump water. Some more affluent people have purchased electric pumps to pump water, but the cost of purchasing electric pumps is higher, and it is also necessary. Pay the electricity fee for later use, and the pump cannot be used in areas without electricity. Therefore, most remote areas or poor areas still use simple pumps. However, due to the intermittent water output of the general hand pump, not only the water output rate is low, but also the water can only f...

AI Technical Summary

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,
