Detailed Description
The invention is further described below with reference to the accompanying drawings, the scope of the invention not being limited to the following:
as shown in figures 1-2, the spray head of the high-efficiency cleaning wet concrete sprayer comprises a quick-change pipe clamp 1, a nozzle sealing assembly 2, a mixer 3, a nozzle sealing base 4 and a rubber nozzle 5, wherein a feed pipe 12 and an accelerator pipe 13 are arranged on the mixer 3, the nozzle sealing base 4 is close to the right end face of the mixer 3, the nozzle sealing base 4 and the mixer 3 are locked through the quick-change pipe clamp 1, and when the quick-change pipe clamp 1 is disassembled, the nozzle sealing base 4 and the mixer 3 are separated. A through hole communicated with the mixer 3 is formed in the nozzle sealing base 4, and a plurality of threaded rods 6 are fixedly arranged on the right end surface of the nozzle sealing base 4 along the circumferential direction of the through hole; the rubber nozzle 5 consists of a large-diameter section, a conical section and a small-diameter section which are sequentially connected, a conveying flow channel is formed in the rubber nozzle 5, the large-diameter section is fixedly arranged in the mixer 3, a plurality of radial holes 7 which are communicated with the mixer 3 and the conveying flow channel are formed in the large-diameter section, and the small-diameter section penetrates through the through hole and extends rightward outside the quick-change pipe clamp 1.
The nozzle seal assembly 2 comprises a rubber seal gasket 8, a seal cylinder 9 and a flange plate 10, wherein the flange plate 10 is arranged outside the seal cylinder 9, one end of the seal cylinder 9 is closed, the other end of the seal cylinder 9 is provided with an opening, the rubber seal gasket 8 is arranged in the seal cylinder 9 and positioned at the bottom of the seal cylinder, the seal cylinder 9 is sleeved on the small-diameter section, and the small-diameter section is propped against the rubber seal gasket 8, so that the rubber seal gasket 8 seals the outlet of the small-diameter section, and simultaneously, under the state that a pipeline has pressure, the small-diameter section of the rubber nozzle 5 expands outwards and is attached to the inner wall of the seal cylinder 9 more tightly, so that a better seal effect is formed, and the cleaning effect is improved.
The threaded rod 6 penetrates through the hole in the flange plate 10, the threaded rod 6 is connected with a locking nut 11 in a threaded mode, the locking nut 11 abuts against the end face of the flange plate 10, and the nozzle sealing assembly 2 is locked in the area formed by the threaded rod 6.
