Description

Technical Field

[0001] The utility model relates to the technical field of spraying slurry loading and unloading, in particular to a loading and unloading device for mine spraying slurry. Background Technique

[0002] Spraying slurry is also known as concrete and aerated block interface treatment. It is a term in construction engineering. When carrying out mine spraying support operations, manual auxiliary feeding and discharging are generally adopted. Workers construct in a complex and harsh environment. The labor intensity of feeding and discharging is high, often making the operators extremely tired, and the construction efficiency is low and the labor cost is high.

[0003] In the Chinese utility model patent application publication number CN220744679U, a loading and unloading device for underground mine spraying slurry is disclosed. Although it includes a vehicle body, the vehicle body is provided with a cargo box, a discharge port is arranged at the tail of the cargo box, a belt conveyor is installed at the bottom of the cargo box, a conveying groove is arranged at the bottom of the cargo box, the belt conveyor is installed in the conveying groove, two guiding inclined plates are respectively installed on both sides of the conveying groove, and a plurality of guiding groove blocks are installed on the upper side of the conveying groove and at the lower ends of the guiding inclined plates. The guiding groove blocks divide the upper side of the conveying groove into a plurality of blanking ports. Chutes are respectively arranged on the opposite sides of adjacent guiding groove blocks. Opening and closing doors are respectively installed in each blanking port, and both sides of the opening and closing doors are slidably installed in the chutes of adjacent guiding groove blocks. When transporting materials, the opening and closing doors are closed, and the materials do not contact the belt conveyor. When discharging materials, the opening and closing doors are opened in sequence to achieve orderly blanking of the materials, so that the belt conveyor is not easily damaged during transportation and discharging, and the materials will not leak to both sides of the belt conveyor. However, this device is provided with a plurality of blanking ports and motors, which not only wastes resources, but also needs to open the opening and closing doors in sequence during blanking, and the operation is cumbersome. At the same time, the belt conveyor of this device extends out of the discharge port, which not only affects safety during transportation, but also easily causes the belt to age in bad weather, affecting its service life.
