Detailed Description

In order to more clearly illustrate the technical solution of the present invention, the following description will be made in conjunction with the accompanying drawings so as to be understood by those skilled in the art. The drawings illustrate only some embodiments of the utility model.

Take a use at agricultural liquid manure integration of lightweight hose pump based on metal stamping forming as an example, the hose pump of casting formula is heavy in weight in the use, inconvenient transport, and only rely on motor control, can't realize accurate automated control. Taking a common three-roller hose pump as an example, the bending plate is the most important part of the housing, and the size of the bending plate directly influences the working performance of the hose pump. According to the utility model, the processing mode and the external structure of the hose pump shell are changed, the low-carbon steel plate is used as the U-shaped bent plate material of the hose pump shell, the hose pump shell is bent into a U shape through the procedures of trimming, bending and the like, and the sealing plate and the shaping plate are correspondingly connected through the bolts; next, the end surfaces of the two sides of the U-shaped bent plate are abutted against the sealing plate, and the U-shaped bent plate is welded with the inner side of the sealing plate; and welding the bent plate and the sealing plate together along the inner edge of the U-shaped bent plate in the shell to complete the assembly of the shell part.

As shown in fig. 1, a pump body of the hose pump is connected with a speed reducer through a coupler, the speed reducer is connected with a motor and is fixed on a base, and the coupler is connected with a main shaft of the hose pump.
