Concrete spraying machine

Abstract

The invention discloses a concrete spraying machine. The concrete spraying machine structurally comprises a sieve-type feeding hopper, a slag discharging hopper, an automatic vibrating sieving device,a damping spring seat, a mixing rotor device, a cyclone, a machine body base, a control electric box, a fixed pipe frame, a controlling wire pipe, a flow-dividing spraying pipe and a moving idler wheel, the sieve-type feeding hopper is of a circular hopper-shaped structure, and the slagging hopper is arranged on the upper portion of the left side of the sieve-type feeding hopper and in penetrating connection with the upper portion of the left side of sieve-type feeding hopper through electrowelding. According to the concrete spraying machine, by arranging the automatic vibrating sieving device, a vibrating device can be automatically started or stopped according to whether raw materials such as cement and sand are added into the feeding hopper or not, the function of immediate starting and immediate stopping is achieved, energy and power are saved, the automation degree of the concrete spraying machine is effectively enhanced, the working efficiency of the concrete spraying machine isimproved, and environmental protection and energy saving are achieved.

Description

technical field [0001] The invention relates to a concrete spraying machine, which belongs to the field of concrete spraying machines. Background technique [0002] Concrete spraying machine is a kind of mechanical equipment that sprays concrete mixture directly on the surface of buildings or structures to strengthen the surface of buildings or form new structures. Concrete spraying machine is the core equipment in shotcrete construction. The mechanical equipment used with it includes manipulators, air compressors, water supply systems, batching and mixing feeding devices, accelerator adding devices, etc. These equipments are equipped with different combinations. A variety of technological processes can be realized, and these devices can also be assembled together to form a triple machine that integrates storage, mixing, and spraying, thereby improving the mechanization of the entire concrete spraying construction process. [0003] But the concrete spraying machine of prior...
