Title:
OSCILLATING ROTARY SEALING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/203943
Kind Code:
A1
Abstract:
Disclosed is an oscillating rotary sealing system, comprising a mixing tank and a sealing cover. The mixing tank is connected to the sealing cover by means of a rotary sealing device. A mixer truck further comprises a stopping mechanism for preventing the sealing cover from rotating together with the mixing tank. When the stopping mechanism is in a braking position, the sealing cover is stationary relative to a truck body of the mixer truck; when the stopping mechanism is in a non-braking position, the sealing cover is driven by the rotary sealing device to rotate together with the mixing tank. The oscillating rotary sealing system further comprises a feeding hopper fixedly mounted on the truck body. A discharging hole is further provided on the sealing cover. In the invention, an oscillating structure controls the position of the discharging hole. When the discharging hole moves together with the sealing cover to a top portion, the sealing cover is closed to achieve rotary sealing so as to prevent spilling. Feeding is performed by means of the feeding hopper. The discharging hole has only the functions of ventilation and gas discharging. When the discharging hole moves together with the sealing cover to a bottom portion, rotary sealing is released so as to perform discharging. The invention has a simple structure, is light, and allows a material to be fed and discharged easily.
