Abstract

The invention discloses a spiral concrete sprayer comprising a base, a nozzle and a motor mounted on the base. A pushing box carrying with a worm is mounted on the base, a delivery pipe is connected to a discharge outlet of the pushing box through a rotating device, the other end of the delivery pipe is connected with a feed inlet of the nozzle, a transmission device allowing the nozzle to rotate is mounted on the side wall of the nozzle, an impeller is arranged in the nozzle, a rotating shaft of the motor is connected with the transmission device and penetrates the outer wall of the nozzle to be connected with the impeller, and an accelerating agent pip is arranged on the side wall of the nozzle. The spiral concrete sprayer is light and flexible in body and convenient for field transportation and construction application, an application range of the spiral concrete sprayer is enlarged, further a power device adopted in the concrete sprayer is in motor drive which replaces original air-operated drive, and manufacturing cost of the concrete sprayer is lowered.

Description

technical field [0001] The invention belongs to the technical field of tunnel and culvert repair machines, tools and equipment, and in particular relates to a spiral concrete sprayer. Background technique [0002] At present, in the construction of small and small projects in foreign developed countries, manipulators are mainly used for sprayed concrete. In my country, due to factors such as manpower, material resources, and financial resources, manual spraying is still the main method of sprayed concrete in small spaces. The dust is large, the construction environment is poor, the labor intensity is high, and the construction quality is difficult to guarantee. Moreover, due to the heavy weight of some concrete spraying equipment, if it is constructed in a culvert, it may also cause subsidence due to too weak foundation soil, which will affect the construction. Therefore, today's concrete spraying equipment tends to be small and light. [0003] In the prior art, there are ma...
