The invention discloses an agitating lorry as well as a rotary sealing structure thereof. The rotary sealing structure comprises an agitating cylinder and a hopper body for charging and discharging; the rear end of the agitating cylinder and the front end of the hopper body are of a nested structure and are sealed mutually; the hopper body can rotate relative to the agitating cylinder; a material opening is formed in the hopper body, and is provided with a material door mechanism capable of opening and closing; the rear end of the hopper body is provided with a support shaft which is used for pushing the hopper body to prop against the agitating cylinder. The hopper body and the agitating cylinder can rotate relatively and are arranged in a sealed mode, and the agitating lorry has the advantages of good seal property, cleanliness and environment friendliness, capability of achieving displacement compensation and abrasion compensation, convenience in oil-way layout and the like.
Description
technical field [0001] The present invention mainly relates to the technical field of engineering machinery, in particular to a rotary sealing structure of a mixer truck and a mixer truck provided with the rotary sealing structure. Background technique [0002] The mixer truck (hereinafter referred to as the mixer truck) is a common transportation equipment used for the transportation of materials such as concrete or mortar. The mixer truck is mainly composed of a chassis and an upper body. Among them, the mixer truck boarding is composed of a tilting mixing drum, a feeding and discharging device, a vehicle frame and other parts. [0003] In the prior art, there is a separate structure between the mixing drum and the feeding and discharging device, and there is no contact between the mixing drum and the feeding and discharging device. On the whole, an open structure is formed at the discharge port at the rear end of the mixing drum. This open arrangement leads to agitation ...
