Hopper device and concrete machinery

Abstract

The invention discloses a hopper device for concrete machinery, which comprises a hopper body (1) used for containing concrete materials, wherein an opened sleeve (2) is sleeved on an upper end part of the hopper body (1). A peripheral wall of the sleeve (2) is matched with and moveably connected to the peripheral wall of the hopper body (1), so that the sleeve (2) can move up and down relative to the hopper body (1). During a process of pouring the concrete, a volume of the hopper device provided by the invention is adjustable, thereby avoiding the overflow of the concrete materials, being capable of adjusting a distance between a feeding port of a hopper and a discharging port of a blender according to a practical condition, adjusting a pumping capability of a pumping power part according to a material position of the concrete materials, and further reducing the escaping of the concrete. Besides, the invention further provides the concrete machinery which comprises the hopper device.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a hopper device for concrete machinery. In addition, the present invention also provides a concrete machine comprising the above-mentioned hopper device. Background technique [0002] Concrete machinery is a typical construction machinery that transports concrete along pipelines to the desired location for construction projects. With the rapid development of my country's economic construction, concrete machinery has been widely used in construction and other fields, and its role is becoming more and more important. [0003] Concrete machinery uses pumps as power, conveys concrete along pipelines, and directly conveys concrete to the pouring site. It is an efficient concrete conveying equipment. At present, piston pumps are mainly used, and piston pumps are mostly driven by hydraulic pressure. It is mainly composed of hoppers, pumping systems, hydraulic system and...

Problems solved by technology

[0006] However, the hopper of concrete machinery in the prior art is fixed on the car body or the ground, its position is not easy to change, and its volume is also fixed. When different types of mixers or concrete mixer trucks unload and During the use of the hopper, the height of the discharge port of the concrete mixer or the transport vehicle from the feed port of the hopper of the concrete machine is too large, resulting in material splashing, and when the amount of material discharged by the concrete mixer or transport vehicle is slightly larger than that of the hopper When the capacity is high, the material is easy to overflow, resulting in waste of material and affecting the environment
