In this embodiment, it should be added that the power cabinet 2 is assembled in the rack 1, the power cabinet 2 is communicated with the swivel base 4, and the driving mechanism 3 located below the power cabinet 2 and the swivel base 4 is assembled in the rack 1.

In this embodiment, it should be noted that, the outer end of the output shaft of the driving mechanism 3 is fixedly sleeved on the main rotary seat of the rotary seat 4, and three sets of traveling wheels with opposite positions are further disposed on the outer side of the frame 1.

In this embodiment, it should be noted that, the top of the frame 1 is provided with a feeding hopper 8 sleeved with the input end of the rotary seat 4, the feeding hopper 8 is a circular hopper, the inner side of the feeding hopper 8 is provided with a vibrating screen, and the outer wall of the feeding hopper 8 is provided with a vibrating motor 9 sleeved with the vibrating screen.

In addition, in the process of long-distance pipeline material conveying, besides accurately mastering the working wind pressure of the jet machine, the fault of the material conveying pipeline is prevented, so that the jet operation can be normally carried out. Blockage generally occurs in three locations, namely, the discharge elbow, the delivery tube, and the muzzle. The main factors causing the pipe blockage are: the materials are not strictly screened, sundries, large stones, long stones and caking water are mixed into the mixture, and the water content of sand and stones is too high, so that the inner wall of a pipeline is bonded; after the spraying operation is finished, the tank body is not cleaned, so that the wall of the tank body is bonded with ash and sand, and when spraying is performed again, a large amount of bonding materials fall off and are mixed into the mixture; in the spraying process, the wind pressure of the spraying machine suddenly and greatly drops and cannot be recovered immediately; the conveying pipe is broken down to generate air leakage, so that the section air pressure is excessively reduced; after the inner wall of the rubber hose is worn, the separation layer is rolled up, so that the material conveying is not smooth; the connecting rubber tube or the spraying rubber tube is seriously bent and flattened; the gate of the water ring of the spray head is not tightly closed, water is accumulated in the rubber pipe, and the water is not blown out by wind in advance; the working wind pressure of the jet machine is too low or the wind quantity is insufficient; the exhaust hole at the upper part of the discharge elbow of the sprayer is not smooth or blocked; the bell-shaped valve is not tightly closed, and the air leakage is serious; sudden power failure, etc. After the pipe is blocked, the easily blocked part is checked first, so that the fault can be removed as soon as possible. In order to find out the blocking position early and correctly, a pipe blocking detection facility should be arranged on the long-distance conveying pipeline, a pressure gauge is generally arranged on the pipeline at intervals of about 50m, the pipeline is checked from top to bottom, if the corresponding pressure gauge of one section indicates that one abnormal pressure is zero, the other pressure gauge is not zero, the pipeline is proved to be plugged, and measures should be taken at the moment to remove the pipe blocking in time. In order to quickly find the pipe blocking position, a signal simulation disc is arranged at the spraying station;

further, as the tubing lengthens, the likelihood of the tubing becoming plugged increases, and care should be taken. In order to reduce and prevent the accident of pipe blockage, the management should be enhanced, and the quality of the pipeline is improved; meanwhile, a driver of the sprayer concentrates on the attention, observes the change condition of the pressure gauge, finds abnormality (sudden pressure rise), and immediately stops feeding and air supply so as to avoid the expansion of a pipe blockage accident and increase the difficulty of discharge.

The working principle and the using flow of the utility model are as follows: when the device is required to carry out corresponding spraying work, two groups of devices are transported to corresponding inclined shaft wellhead positions in advance, then the wind pressure of corresponding angles is carried out on materials by adjusting the angle of the wind pressure pipe 10 and the pressure value of the wind pressure machine according to the inclination of the inclined shaft, the surrounding environment and the length of the conveying pipe 7, then the conveying pipe 7 can be matched to carry out full-automatic material conveying on the materials, the conveying effect of the device on the materials is guaranteed, and the problem that the existing device is difficult to carry out corresponding efficient spraying on the materials according to the requirements is solved.
