Summary:The invention relates to a concrete sprayer with a horizontal rotor of a side blowing type, comprising a mechanical transmission structure, a hopper, a jet valve and a barrow. The hopper is internally provided with a screen and a horizontally arranged loosening device, the jet valve is internally provided with a rotor, a transmission shaft, an axial sealing ring, a radial compensating and sealing device and an air cylinder, concrete falls from the hopper into a material cavity of the jet valve and is plucked by the rotor to the lower part of the jet valve, compressed air is blown into a valve body from one side of the periphery of the jet valve in a direction crossed with the axial direction of the rotor, and concrete is conveyed out of the jet valve at a high speed from the same side so as to achieve of the spraying effect. Compared with the prior art, the invention not only reduces the sealing area, but also has better sealing performance, simple structure, little power consumption, high stability and good
