A concrete mixer with a hopper door that opens outwards and whose drum residues are easy to remove

Abstract

The invention discloses a concrete mixer whose hopper door is opened outwards and the residual material of the drum is easy to remove. Fix the support rod, the water pump pipeline, and the transmission case. The transmission guide rail bracket is equipped with a cable transmission mechanism, a mixer control mechanism, a mixer transmission gear set, and a residue removal mechanism. Screws and return springs can prevent the concrete residue from adhering to the inner wall of the rotating mixing drum when the equipment is in use. Because it is difficult to clean up, more and more concrete will accumulate, which will affect the working quality of the rotating mixing drum and make the concrete mixing Unevenness will lead to deformation of the rotating mixing drum in the long run. The design of the external protective cover can automatically clean up the residue inside the rotating mixing drum, saving manpower and material resources, and shortening the construction process.

Description

technical field [0001] The invention relates to a concrete mixer with a hopper door open outwards and easy removal of drum residues, which belongs to the field of concrete mixers. Background technique [0002] Concrete mixer with hopper is the most commonly used construction machine in construction machinery. The existing domestic concrete mixer with hopper has two walking wheels on the track, and the other four walking wheels walk in the track. When the hopper is lifted to a certain When the height is high, the roller on the hopper collides with the rocker arm of the electrical limit switch, the motor stops and brakes, and the hopper unloads into the drum of the mixer by itself, but the hopper door and door latch of the existing mixer are installed inside the hopper. It often happens that the latch cannot be pulled out, the door cannot be opened, or the hopper door can only be partially opened due to the sandstone cement in the hopper. In addition, the upper and lower trav...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a concrete mixer with the hopper door open outwards and the residual material of the drum is easy to remove, so as to solve the problem that the drum of the traditional mixer is not removed in time after construction. The concrete on the inner wall of the drum and the corners of the roots of the mixing blades will lead to more and more concrete attached to the inner walls of the drum and the corners of the roots of the mixing blades and it is difficult to remove. Workers have to use hammers, shovels, wooden sticks, etc. to beat the drums to remove them The residue attached to the drum can only remove a small part of the inner wall of the drum, but it is easy to deform the surface of the drum such as protrusions, grooves, cracks, etc., which will be further aggravated by the rough surface of the drum. The amount of concrete attached to the inner wall of the drum will seriously affect the production, working efficiency and service life of the mixer
