Agricultural irrigation water pump with decontamination and anti-blocking functions

Abstract

The invention disclose an agricultural irrigation water pump with decontamination and anti-blocking functions. The water pump is characterized in that a connecting base is arranged at a water inlet of a pump body, the connecting base is connected with a water inlet flange of the pump body, a limiting mechanism is arranged at the end, away from the water inlet of the pump body, of the connecting base, the other end of a sliding rod is connected with a second end cover in a sleeved mode, the sliding rod is in bolted connection with the second end cover, a plurality of third connecting holes are fixedly connected with one ends of a plurality of connecting rods, and the other ends of the plurality of connecting rods penetrate through a decontamination brush to be fixedly connected with a shell. According to the agricultural irrigation water pump with the decontamination and anti-blocking functions, irrigation water is filtered by means of a filter sleeve, and when the outer wall of the filter sleeve is blocked by accumulated dirt, water pressure can push the second end cover and a first end cover to move towards the water inlet, so that the outer wall of the filter sleeve makes contact with the decontamination brush, decontamination operation on the surface of the filter sleeve is achieved, pressure stabilization is realized through the cooperation of the limiting mechanism, the first end cover, the second end cover, the connecting rods and a push block, and finally resetting of the filter sleeve is realized under action of a disc spring.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation water pumps, in particular to an agricultural irrigation water pump with the function of cleaning dirt and preventing blockage. Background technique [0002] Agricultural irrigation mainly refers to the irrigation of agricultural farming areas. Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation and micro-irrigation. Water pumps are used in agricultural irrigation operations, and water pumps are machines that transport liquids or pressurize liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals. Water pumps can also transport liquids and gases. Mixtures and liquids containing suspended solids. The technic...
