The invention discloses a sealing device for a truck-mixed concrete stirring cylinder, belonging to a sealing device. The sealing device for the truck-mixed concrete stirring cylinder structurally comprises an observation door, a middle connection door and a discharging door; the upper part of the middle connection door is hinged with the observation door, and the lower part of the middle connection door is hinged with the discharging door; the middle connection door is connected with the feeding hopper through a round cylinder; a semicircular hole is formed in the upper part of the discharging hopper; the round cylinder is located at the upper part of the bottommost end of the semicircular hole; a feeding opening of the feeding hopper extends into a feeding cone of the stirring cylinder along the round cylinder; a water pipe is arranged at the inner side of the round cylinder; one end of the water pipe is plugged; two rows of staggered spraying holes with a diameter of 4 mm are arranged on the pipe wall; and the other end of the water pipe is connected with an upper water hose by extending out from the round cylinder. Compared with the prior art, with the adoption of the sealing device for the truck-mixed concrete stirring cylinder provided by the invention, the dust raising problem in a stirring process of the truck-mixed concrete stirring cylinder can be effectively controlled, so that the sealing device has good popularization and application values.
Description
technical field [0001] The invention relates to a sealing device, in particular to a sealing device for a truck-mixed concrete mixing drum. Background technique [0002] With the development of society, more and more environmental issues have become a topic of concern. Therefore, in the machinery manufacturing industry, how to effectively avoid environmental pollution during the construction and manufacturing of products has gradually become a priority in the design process. [0003] The truck-mixed concrete mixer truck not only has the transportation function of the traditional mixer truck, but also has the function of concrete mixing—that is, the truck-mixed concrete prepared by the dry material station can be directly put into the mixing drum of the truck-mixed concrete mixer truck, and the mixing drum will carry out the mixing. . However, due to the fact that truck-mixed concrete is easy to generate dust during the mixing process, ordinary mixing drums cannot effective...
