Description

Concrete belt conveying and pumping integrated machine

Technical Field

The invention relates to mechanical equipment for construction, in particular to a concrete belt conveying and pumping integrated machine.

Background

The boom pump truck has the functions of integrating pumping and distributing, and along with the promotion of urban construction, a great deal of boom pump truck is used in rural construction houses, but because rural commodity concrete mixing stations are not popular, rural areas are mostly stirred in a field stirring mode, the stirring and the distributing work of the boom pump truck is completed by different machines, the different machines need to be matched in specification, the occupied area is large, the installation and the debugging are labor-consuming and time-consuming, the production efficiency is low, the rural stirring equipment speed is too slow, and the pumping speed is far behind that of the boom pump, so that the equipment is wasted; in addition, the rural roads are narrow, and some equipment is difficult to reach the final construction site, so that the rural labor force is scarce year by year and the manual commission rises year by year; moreover, in the foundation concrete pouring process of rural house construction, the requirement on the particle size of concrete is high, but the requirement of the cantilever crane pump truck is often not met by the particle size of the concrete required by rural house construction, so that people think that the concrete required by rural house construction is conveyed by using a belt conveyor, but the belt conveyor for concrete conveying in the market at present does not have the functions of automatic feeding of concrete raw materials and concrete conveying, so that the design of the medium-and small-sized integrated belt conveyor suitable for stirring and conveying of the concrete in villages and towns is needed.

In order to solve the problems, he invented a 'boom pump truck with a forced mixer' (application number CN 201621119292.1), which adds a forced mixer at the rear part of the automobile body and adopts a foldable feeding device, so as to solve the defects of non-integration of mixing and conveying and the defect of larger volume and inconvenience in driving in rural sections compared with the traditional boom pump truck. However, the requirement of the cantilever crane pump truck on the particle size of concrete is high, the particle size cannot be too large, but the particle size of the concrete required by rural house construction cannot meet the requirement of the cantilever crane pump truck, and the phenomenon of blockage of a concrete pumping pipeline is easy to occur. On the basis, others invented a mobile belt conveyor (patent number: CN 201620320714.5) for pouring concrete in a turning block, the requirement on the size of concrete particles is not high by conveying the concrete through the belt conveyor, but the mobile belt conveyor does not have the function of automatically feeding and stirring the raw materials of the concrete, so that the whole concrete stirring pouring operation can be realized by being matched with a plurality of devices, and the existing three-in-one arm support pump is inferior.

Therefore, the design of the integrated machine with the functions of belt conveying and pumping is very necessary when the height of a concrete using site is not high and the requirement on concrete particles is not high, the belt conveying can be adopted for low-altitude operation, and when the height of concrete pouring operation is high, the pumping function can be adopted for pumping concrete to the high-altitude operation site, meanwhile, the labor intensity can be reduced, and the equipment in rural markets can be served in a faster, better and more environment-friendly mode.
