Dry-and-wet dual-use automatic continuous slurry loading and spraying car

Abstract

The invention relates to a dry-and-wet dual-use automatic continuous slurry loading and spraying car, which comprises a traveling device and a stock bin, wherein a frame is arranged on the traveling device, the stock bin is erected above the frame in a hinged manner, and a slurry spraying machine is also arranged on the frame; a first conveying device is hooked at the bottom of the stock bin, the bottom of the stock bin is communicated with the first conveying device, a discharge outlet is formed in one end of the first conveying device, the slurry spraying machine is arranged right below the discharge outlet of the first conveying device, a lifting device is arranged at the tail part of the frame and consists of a rack and a second conveying device, the second conveying device is arranged in the rack and consists of a horizontal section and an oblique section, the height of the second conveying device is greater than or equal to that of the stock bin, a feed hopper is arranged above the horizontal section of the second conveying device, and two side walls of the feed hopper are fixedly connected with the rack. The dry-and-wet dual-use automatic continuous slurry loading and spraying car has the advantages of being simple in structure, high in space utilization rate, and wide in applicability.

Description

technical field [0001] The invention belongs to the field of tunnel mining equipment, in particular to an automatic feeding spraying device. Background technique [0002] Currently used in the tunnel construction process, the spraying grouting machine for concrete injection pouring generally adopts two methods of manual feeding or automatic feeding with a dumping bucket. Among them, the manual loading method has disadvantages such as high work intensity, serious spillage of concrete materials, and slow loading speed; while the tipping bucket automatic loading vehicle not only has the hopper height too high when loading, but also needs to be used in a large space Carry out normal feeding operations, and it is impossible to achieve continuous feeding, thereby greatly reducing the progress of the project; in addition, the tipping bucket type automatic feeding vehicle needs to use supporting devices such as hydraulic jacks or hydraulic cylinders to jack up the moving end of the ...

AI Technical Summary

Problems solved by technology

Although this feeding gunite machine can realize the function of automatic and continuous feeding, there are still many disadvantages: (1) The silo still needs to be supported by the oil cylinder to rotate around the rotating shaft, which consumes a lot of energy and costs. During the feeding process, the weight of the silo and the concrete in it is fully supported by the oil cylinder, and the oil cylinder is in a state of high pressure jacking up for a long time, which has potential safety hazards; When feeding, the outlet of the silo is easy to block, resulting in poor feeding; (3) The use of belt pulleys to transport materials will not only cause the materials to roll in the opposite direction under the action of gravity, but also the materials are easy to move in the horizontal direction. spread out, causing material leakage at the end of the pulley when unloading

However, in order to ensure safety, the height of the climbing ladder is limited, and in order to unload the materials in the transport truck compartment into the silo, the transport trolley compartment must be able to turn over to the top of the silo. This requirement cannot be met in the case of trucks; moreover, the overturning of the cargo truck compartment also requires a large space, which greatly reduces the space utilization rate. However, the space in the tunnel is small, and the rational use of space is particularly important.
