Automatic feeding spray truck

Abstract

The invention discloses an automatic feeding type concrete spraying trolley which comprises a trolley body, a storing bucket, a feeding bucket and a concrete spraying machine, wherein the feeding bucket is hinged to the trolley body, a first hydraulic cylinder is arranged between the feeding bucket and the trolley body, the cylinder body of the first hydraulic cylinder is hinged to the trolley body, a pushing rod of the first hydraulic cylinder is hinged to the feeding bucket, and an automatic flash setting admixture adding device is arranged on the feeding bucket. The automatic feeding type concrete spraying trolley has the advantages that due to the fact that materials and admixtures can be added automatically, labor cost is reduced and working efficiency is improved; the concrete spraying machine is integrated with the trolley, and therefore fast transportation can be achieved; when the first hydraulic cylinder ascends, the feeding bucket inclines backwards to pour remaining materials back into the storing bucket, and a larger operating space is provided for replacement and maintenance of the concrete spraying machine.

Description

technical field [0001] The invention relates to engineering machinery, in particular to an automatic feeding spraying vehicle. Background technique [0002] Shotcrete machines are widely used in engineering construction, mines, tunnels, culverts, subways, hydropower projects, underground projects and coal high marsh mine roadway shotcrete construction operations. But existing shotcrete machine still has many defects when used alone. [0003] First, the existing shotcrete machine is cumbersome to load, and the automation of the feeding system is low. Many workers are still required to load materials to ensure the normal operation of the shotcrete machine. The work intensity of the workers is high, the working environment is poor, and the labor cost is also high. [0004] Second, the existing shotcrete machine is driven by vehicles or transported by vehicles, which is inefficient. [0005] Third, additives such as accelerators need to be manually added, which is cumbersome t...

But existing shotcrete machine still has a lot of defects when used alone

[0003] First, the existing shotcrete machine is troublesome to load, and the automation of the feeding system is low. Many workers are still required to load materials to ensure the normal operation of the shotcrete machine. The work intensity of the workers is high, the working environment is poor, and the labor cost is also high.

[0004] Second, the existing shotcrete machine is driven by vehicles or transported by vehicles, which is inefficient

[0005] Third, additives such as accelerators need to be completed manually, which is cumbersome to add and cannot achieve the effect of automatic addition with a simple structure

[0006] Fourth, when the shotcrete machine breaks down, it is not easy to disassemble and repair it because of the blockage of the car body and the supply hopper
