Agricultural irrigation pump mechanism with sludge-water separation function

Abstract

The invention relates to the field of agricultural irrigation equipment, in particular to an agricultural irrigation pump mechanism with a sludge-water separation function. The agricultural irrigationpump mechanism comprises a centrifugal cylinder; the centrifugal cylinder communicates with a water outlet pipe tangentially communicating with the centrifugal cylinder, and a filter screen is embedded at the communicating position between the water outlet pipe and the centrifugal cylinder; and the centrifugal cylinder communicates with a sludge discharging pipe tangentially communicating with the centrifugal cylinder. According to the agricultural irrigation pump mechanism, through arrangement of the filter screen at the communicating position between the water outlet pipe and the centrifugal cylinder, and the sludge discharging pipe tangentially communicating with the centrifugal cylinder, sludge in centrifuged muddy water is intercepted by the filter screen under the action of an impeller, and discharged into the sludge discharging pipe under the action of centrifugal water flow, so that efficient separation of the sludge and the water is realized; the sludge is prevented from being irrigated into a field while the pipeline is protected, and crops are protected; and through arrangement of the sludge discharging pipe, an end cover, a pushing roller, a pushing rod and a crank sliding block mechanism, the sludge is discharged from the sludge discharging pipe.

Description

technical field [0001] The invention relates to the field of agricultural irrigation equipment, in particular to an agricultural irrigation pump mechanism with mud-water separation function. Background technique [0002] Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation and micro-irrigation. Traditional surface irrigation includes border irrigation, furrow irrigation, flood irrigation and flood irrigation, but these irrigation methods often consume a lot of water and have low water utilization efficiency, which is a very unreasonable agricultural irrigation method. In addition, ordinary sprinkler irrigation technology is a relatively common irrigation method in China's agricultural production. However, the water utilization efficiency of ordinary sprinkler irrigation technology is not high. Modern agricultural micro-irrigation techniques include micro-sprinkler irrigation, drip irrigation, infiltrati...

Problems solved by technology

[0004] In agricultural irrigation, irrigation pumps are often used to pump the water in the ditch to the farmland. During the pumping process, the sludge in the ditch is easily sucked into the pump body together, which is easy to cause sludge to accumulate in the pump body, affecting the pumping efficiency and easily causing sludge.
