Abstract

The invention discloses a pumping system and an engineering machine. The pumping system comprises a hopper and a water tank, wherein the hopper and the water tank are arranged on a secondary beam. The two ends of the water tank are connected with a conveying cylinder and a main oil cylinder respectively, and the conveying cylinder is located between the hopper and the water tank. The pumping system further comprises a vertical plate transversely arranged along the secondary beam, and the water tank is mounted on the secondary beam through the vertical plate. According to the pumping system, through the flexibility of the vertical plate, assembling errors can be eliminated. In addition, the strength of the secondary beam and the impact resistance of the system can be enhanced, and the service life of easily damaged parts is prolonged.

Description

technical field [0001] The present invention mainly relates to the technical field of construction machinery, in particular, to a pumping system and construction machinery provided with the pumping system. Background technique [0002] The pumping system is a key component of construction machinery such as concrete pump trucks, trailer pumps, truck-mounted pumps, wet spray machines, industrial pumps, mixing pump trucks, and mortar pumps. In the prior art, the installation methods of the pumping system are mainly divided into two types: fixed type and hinged type. [0003] Among them, the fixed installation structure is affected by the machining accuracy, positioning accuracy and welding deformation of the parts, which leads to the need to adjust the water tank mounting seat plate on site during installation, and then weld the water tank mounting seat. The welding is time-consuming and laborious, and the accuracy is difficult to control. Deformation can easily lead to struct...
