Embodiment Construction
[0025] In order to better illustrate the present invention, the present invention will be described in detail with a preferred embodiment and with accompanying drawings, specifically as follows:
[0026] Such as figure 1 , figure 2 As shown, the screw lift combined agricultural water pump provided in this embodiment includes a first motor 10 , a spiral flow constant pressure pump 20 and an inner lift screw pump 30 , wherein the inner lift screw pump 30 is driven by the second motor 40 . Wherein, the internal lift screw pump 30 includes a cylindrical shell 31, and a shaftless screw rod 32 is arranged inside the shell 31, and the shaftless screw rod 32 cooperates with the inner wall of the shell 31 and can move relatively.
[0027] Specifically, the helical flow constant pressure pump 20 has a central shaft 21 , the power output shaft of the first motor 10 is connected to the central shaft 21 , and the helical flow constant pressure pump 20 can be powered to work through the c...

The invention provides a spiral lifting combined agricultural water pump, which includes a first motor, a spiral flow constant pressure pump and an internal lift type screw pump, the first motor is connected with the spiral flow constant pressure pump, and the output port of the internal lift type screw pump is connected to the The water inlet of the spiral flow constant pressure pump can be detachably connected; among them, the internal ascending screw pump includes a cylindrical casing, and the casing is equipped with a shaftless screw rod, which is matched with the inner wall of the casing and can move relatively without The shaft screw is driven by a second motor. The screw lift combined agricultural water pump can realize low-speed inner lift screw pump water delivery when the spiral flow constant pressure pump and the inner lift screw pump are connected according to needs; and the inner lift screw pump is disconnected, the first motor and The centrifugal pump is directly coupled. The internal lift screw pump can fill the constant pressure pump with water first before the centrifugal pump starts to work, so there is no need to fill the constant pressure pump with water before running. The screw lift combined agricultural water pump can flexibly change the use mode according to user needs.
Description
technical field [0001] The invention relates to the technical field of agricultural water pumps, in particular to a screw lifting 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 aquati...
