Concrete mixer with shock absorption device

Abstract

The invention discloses a concrete mixer with a shock absorption device. The concrete mixer with the shock absorption device includes a vehicle frame, a concrete mixing barrel is arranged above the vehicle frame, the vehicle frame supports the front part of the mixing barrel through a front part bracket and a mixing device bracket, the rear part of the mixing barrel is supported on the vehicle frame through a rear part bracket, a first shock absorption device is arranged between the front bracket and the mixing device bracket, a connecting plate connected to the rear part of the mixing barrelis arranged above the rear bracket, a second shock absorption device is arranged between the connecting plate and the rear part bracket, the first shock absorption device is of the same structure as the second shock absorption device, wherein the first shock absorption device includes a top plate and a bottom plate, the top plate and the bottom plate are connected through a plurality of strong springs, and a lifting buckle for lifting is arranged on the vehicle frame. According to the concrete mixer with the shock absorption device, the vibration of the concrete mixing barrel is prevented frombeing transmitted on the device, the vibration does not affect the structure of the device and cause damage, the service life is prolonged, and dusts on the ground are not raised due to vibration when the device is placed on the ground.

Description

technical field

[0001] The invention relates to the technical field of concrete mixing, in particular to a concrete mixer with a shock absorbing device. Background technique

[0002] Due to the particularity of the structure and location of subways, tunnels, bridge boxes, etc., a large amount of concrete is required for the pouring of the overall track bed. General-purpose concrete pump trucks and concrete mixer trucks cannot directly reach the working face, and the concrete pump is limited by the conveying distance. At present, when pouring the integral track bed in subway construction, the commonly used method for concrete delivery is: to make a trough, fill the trough with concrete, transport it to the vicinity of the site by a rail flat car, and then lift it to the working surface for pouring by the gantry. Due to the long transportation distance, the concrete cannot be stirred after being stored in the trough for a long time, the concrete segregation is very serious, it...
