Description

Technical Field

[0002] At present, wet spraying machines are widely used in structural support operations such as slopes and mine tunnels. However, in actual use, it is found that during operation, the current wet spraying equipment is often directly connected between the feeding, mixing and spraying equipment, which leads to pressure leakage during material feeding, mixing and spraying operations, and thus leads to poor stability of spraying pressure, low material feeding efficiency, and even material backflow, which seriously affects the efficiency and quality of spraying construction operations; on the other hand, traditional spraying machines often do not have autonomous operation capabilities or adopt a walking structure based on walking wheels during operation, so their walking and mobility capabilities are poor, and their adaptability to complex road conditions during walking and mobility is relatively insufficient, which cannot meet the needs of complex working environments and spraying processes, seriously affecting the work efficiency and quality of spraying work.

The guide groove is coaxially distributed with the material port, and its lower end surface is connected to the upper end surface of the supporting cylinder, and the area of ​​the upper end surface of the guide groove is at least 1.5 times the area of ​​the material port. The stirring mechanism is embedded in the supporting cylinder and coaxially distributed with the supporting cylinder, and one end of the stirring mechanism is connected to the stirring motor through a transmission shaft and coaxially distributed.

[0010] Furthermore, the lower end surface of the connecting rod flipping mechanism is connected to the upper end surface of the crawler chassis, and the upper end surface is connected to the outer surface of the mixing box and the receiving box through a slide groove, and the axis of the connecting rod flipping mechanism forms an angle of 0°-135° with the upper end surface of the crawler chassis.
