Power switch combined agricultural water pump

Abstract

The invention provides a power switching combined agricultural water pump, which includes a motor, a manual drive and an inner-lift screw pump, the motor and the manual drive are connected to a conversion device, the conversion device is connected to the inner-lift screw pump, and the conversion device It is used to switch between the motor and manual drive to select one of them to provide power for the internal lift screw pump; wherein, the conversion device includes a universal coupling, a power transmission shaft and a gear changer, and the gear changer and The motor and the manual drive are switched and connected to drive the power transmission shaft to output power to the internal ascending screw pump through the universal coupling. The power switching combined agricultural water pump can provide power for the inner-rising screw pump by turning on the motor or manually driving according to needs, and the two can be freely switched through the conversion device to meet the power of the inner-rising screw pump in different situations need. The power switching combined agricultural water pump can be widely used in various agricultural drainage and irrigation sites.

Description

technical field [0001] The invention relates to the technical field of agricultural water pumps, in particular to a power switching combined agricultural water pump. Background technique [0002] It is well known that agricultural drainage and irrigation will encounter various complex situations: (1) If a large amount of irrigation and drainage is required for a certain period of time, the traditional method is to use multiple water pumps to work at the same time, which will inevitably cause waste of resources and increase equipment and labor costs; (2) When the terrain of crops is high and the water source is low, multi-stage centrifugal pumps are used for transportation; (3) Flexible transportation is required for changing water in fish ponds to prevent damage to fry; (4) Submersible pumps are used for sludge, impurities, aquatic plants and particles The sundries are sensitive, so a filter needs to be installed outside the pump. After working for a period of time, the aqua...
