Description

Walking stirring device Technical Field The application relates to the technical field of stirring machinery, in particular to a walking stirring device. Background In the engineering fields of building construction, road construction and the like, concrete is used as a key building material, and the maintenance of homogeneity and fluidity in the transportation process is important. At present, the mode of adopting the electric locomotive to pull the special transport vechicle to accomplish the short-distance or well short-distance transport of concrete in the engineering generally, this kind of transport mode provides the traction power through the electric locomotive, realizes the high-efficient transportation of concrete in the construction site. However, the concrete is extremely easy to generate aggregate sedimentation, segregation and other phenomena due to the action of gravity in the standing or transportation process, so that the performance of the concrete is reduced, and the construction requirement cannot be met. To solve this problem, in the prior art, an independent stirring motor is usually required to be additionally arranged on the transport vehicle, and the stirring blade is driven by the stirring motor to stir the concrete in real time so as to ensure the uniformity of the concrete. The combined mode of electric locomotive traction and independent stirring motors can meet the concrete transportation requirement to a certain extent, but has the obvious problems of high cost and energy efficiency, namely, on one hand, the additionally arranged stirring motors need independent power supply systems (such as special storage battery packs or external cables), so that the purchase cost of equipment is increased, the later maintenance cost is also improved, on the other hand, the electric locomotive and the stirring motors independently operate, the energy conversion efficiency of the two sets of power systems is difficult to cooperatively optimize, the whole energy consumption is higher, and the development requirements of the current engineering field on energy conservation and consumption reduction are not met. In addition, the installation of the independent stirring motor increases the overall weight and structural complexity of the transport vehicle, and may adversely affect the traction performance of the electric locomotive, while also limiting the effective loading space of the transport vehicle. Therefore, how to simplify the equipment structure, reduce the cost and improve the energy utilization efficiency on the premise of ensuring the stirring effect in the concrete transportation process becomes a technical problem to be solved in the field.
