Concrete mixing hopper mandrel

Abstract

The invention discloses a concrete mixing hopper mandrel for small mechanical equipment. The concrete mixing hopper mandrel comprises a rotating main shaft, wherein the cross section of the rotating main shaft is rectangular, rectangular clamping grooves which are evenly distributed are formed in the rotating main shaft, and the cross section of each clamping groove is rectangular; two mounting supports are buckled in the clamping grooves of the rotating main shaft, and mixing heads are welded to one mounting support; and the outer ends of the mixing heads are fixedly connected with wear-resisting plates through bolts. According to the concrete mixing hopper mandrel for the small mechanical equipment, mounting of the mixing heads is completed through the rotating main shaft with the rectangular clamping grooves and the separated mounting supports, the structural strength of the rectangular rotating main shaft is not damaged, overall replacement of the mixing heads is facilitated, and maintenance is convenient; and the mixing heads are mounted progressively, so that it is guaranteed that concrete slurry is accumulated towards the middle, mixing of concrete slurry at the edge part can be ensured, and the mixing quality is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a concrete mixing bucket mandrel for small mechanical equipment. Background technique [0002] Concrete mixing buckets belong to construction engineering mechanical equipment, which are used in infrastructure, roads and bridges, coal mine engineering and other fields. The mobile concrete mixing equipment in the market mainly relies on electricity, machinery, and hydraulic pressure to drive the rotation of the stirring mandrel. Stirring heads with different structures are arranged, and the rotation of the mandrel drives the stirring heads to rotate, further achieving the purpose of mixing slurry. In order to meet the needs of mixing and mixing operations for different slurries, there are various types of mixing mandrel structures. Traditional concrete mixing equipment often has problems such as uneven mixing, long unloading operations, and large slurry residues, whic...

AI Technical Summary

Problems solved by technology

[0005] The threaded through hole on the stirring shaft will reduce the strength of the stirring shaft, causing the stirring shaft to be easily twisted and deformed; the stirring head is a wearable part, which needs to be replaced and maintained regularly. Since the stirring head is installed in the threaded through hole, it is not conducive to disassembly and replacement, especially the stirring shaft When there is a certain twist and deformation, it is easy to get stuck on the threaded column end of the stirring head, and the deformed threaded through hole is not conducive to the installation of a new stirring head
