Concrete mixing tank noise reduction structure for concrete transportation vehicle

Abstract

The invention belongs to the field of concrete transportation equipment, and specifically discloses a concrete mixing tank noise reduction structure for a concrete transportation vehicle, and the structure comprises a tank body and an obliquely arranged pedestal. A shaftless double-helical blade is rotationally connected in the tank body, and the double-helical blade is hollow at a center line thereof. A right end of the double-helical blade is fixed on the pedestal, a left end of the double-helical blade is fixedly connected with a bearing disk having a center hole, an outer ring of the bearing disk is rotationally connected with an inner wall of the tank body through a bearing, a rotating shaft is arranged at a hollow part of the double-helical blade, the left end of the rotating shaft is fixedly connected at the left end of the tank body, four baffles are fixed at circumferential sides of the rotating shaft and form a cross, the baffles are made of plastics, the baffles are providedwith several leaking holes, and an inner ring of the bearing disk is rotationally connected with the rotating shaft. An end part of the baffle is fixedly provided with a muntin, and a slot hole is formed between the muntin and the baffle. With the structure provided by the scheme of the invention, noise, generated when stones in concrete fall down and collide with the tank body, can be reduced.

Description

technical field [0001] The invention belongs to the field of concrete transportation equipment, and in particular relates to a noise reduction structure of a concrete mixing tank used for a concrete transportation vehicle. Background technique [0002] Urban noise refers to all kinds of noise generated by construction, transportation, industrial production and daily life in the city. The interference and harm of urban noise to residents are becoming more and more serious, and it has become a major public hazard to the urban environment. Urban noise mainly includes: traffic noise, industrial noise, building construction noise, and social life noise. Urban noise interferes with residents' work, study, rest and sleep, and seriously endangers human health, causing diseases and noise-induced deafness. [0003] Concrete mixer truck or mixer truck is a special truck used to transport ready-mixed concrete for construction; because of its shape, it is also often called a snail truc...

AI Technical Summary

Problems solved by technology

However, during the mixing process, the stones in the concrete rise to the upper part of the tank under the action of centrifugal force, and when they fall down, they collide with the side wall of the tank and the noise generated has a great impact on the environment.
