Problems solved by technology

The supporting wheel assembly of this structure, because the two supporting wheels can swing, when the central axis of the mixing drum is not aligned, the centering can be automatically adjusted through the swing of the two supporting wheels, so that the central axis of the mixing drum is aligned; but The supporting wheel assembly of this structure is rigidly connected with the body of the mixer truck. When the mixer truck is running fast on bumpy and potholed roads, the jumping of the mixing drum produces an impact on the supporting wheel assembly. When the impact is large, the mixing The cylinder and supporting wheel assembly are easily damaged
[0006] The middle part of the mixing drum of some large-scale concrete mixer trucks is also equipped with an intermediate raceway, which is supported by the above-mentioned two supporting wheel assembly of the supporting wheel structure, here forming the

Abstract

The invention relates to the technical field of agitating lorries, and discloses a support device, which is used for supporting an agitator drum of an agitating lorry. The support device comprises a riding wheel assembly, wherein the bottom end of the riding wheel assembly is fixed to a lorry body of the agitating lorry through an elastic device. The bottom end of the riding wheel assembly of the support device is fixed to the lorry body of the agitating lorry through the elastic device; and when the agitating lorry runs on bumpy and uneven roads quickly, the impact generated by the upward jumping of the agitator drum can be absorbed by the elastic device, so that the impact generated by the upward jumping of the agitator drum can be reduced, and the agitator drum and the riding wheel assembly are protected effectively. The invention also discloses the agitating lorry.

Description

technical field [0001] The invention relates to the technical field of mixer trucks, in particular to a support device for supporting a mixer drum of a mixer truck, and also relates to a mixer truck. Background technique [0002] Concrete mixer truck (abbreviated as mixer truck in this application) is a common concrete transportation equipment. The chassis of the mixer truck is equipped with a mixing drum to carry the mixed concrete. During transportation, in order to ensure that the carried concrete will not solidify, the mixing drum must always keep rotating. [0003] In order to make the mixing drum rotate normally, the front and rear ends of the mixing drum are provided with supports, and the front end of the mixing drum is connected with the chassis to form a front support; the rear cone part of the mixing drum is provided with a rear cone raceway, and the body of the concrete transport vehicle The supporting roller assembly for supporting the mixing drum is arranged a...
