Abstract

The application relates to the technical field of concrete spraying equipment, in particular to a spraying machine which comprises a spraying pipe, a trolley body, a limiting ring and a locking assembly. The limiting ring is arranged on the trolley body and is used for fixing the spraying pipe. An operator pushes the trolley body along a straight line for a distance, and moves multiple wheel bodies in the same direction. At this time, the multiple wheel bodies are locked by the locking assembly, so that the wheel bodies cannot be turned randomly, and the distance between the spraying pipe and a building surface is determined. Then, the operator can stably move the trolley to spray concrete in the transverse direction, and the limiting ring is deflected by a moving handle, so that the operator can adjust the angle of the spraying pipe. Meanwhile, the operator can sit on the trolley body, so that the stability of the trolley is improved by using the gravity of the operator. In addition, the trolley body can be moved to spray concrete by rotating a hand wheel, so that the operation is simple, convenient and labor-saving.

Description

Technical Field

[0001] The present invention relates to the technical field of concrete spraying equipment, in particular to a spraying machine. Background Art

[0002] Concrete spraying machine is a kind of construction equipment widely used in engineering construction. It uses compressed air or other power to transport the mixture prepared in a certain proportion through a pipe and spray it at high speed onto the sprayed surface to solidify and harden, thereby forming a concrete support layer. The spraying technology is simple, the construction cost is low, and it has a wide range of adaptability. It plays an important role in various construction fields. In the existing technology, there is a mechanical arm installed on the main body of the sprayer to operate the nozzle to spray concrete. However, in actual usage scenarios, there are some places that large machinery cannot enter well. At this time, manual hand-held nozzle spraying is required. Due to the large recoil of the nozzle, two workers are generally required to work together to stabilize the nozzle. Specifically, one worker presses the concrete conveying pipe to the ground, while the other worker clamps the conveying pipe close to the nozzle between his legs and uses both hands to hold the nozzle tightly. Only in this way can the spraying work be completed stably and smoothly, which consumes the workers' energy. For this reason, we propose a spraying machine. Summary of the Invention
