Description

Technical Field

[0001] This utility model relates to the field of concrete batching and mixing technology, and in particular to a mixing blade for a concrete batching and mixing drum. Background Technology

[0002] During the construction process, a large amount of concrete is used. After the existing concrete is batched, it is put into a concrete mixer for mixing to produce finished concrete. During this process, the mixing structure inside the mixing drum is required to mix the concrete. The mixing structure generally includes a central shaft and mixing blades.

[0003] Existing concrete mixing drums often suffer from bending, deformation, or even breakage of their mixing blades during prolonged mixing processes. Furthermore, the thick layer of concrete adhering to the blades makes disassembly, replacement, and cleaning impossible. This increases the volume and weight of the rotating mixing structure, hindering concrete mixing and consuming more energy. Additionally, disassembling the blades for maintenance and replacement is inconvenient, requiring the complete disassembly of the mixing structure, which is cumbersome, time-consuming, and wasteful.

[0004] Therefore, we provide a mixing blade for a concrete batching and mixing drum. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a concrete batching and mixing drum mixing blade that allows for the disassembly, replacement, and maintenance of the connecting drum, the first blade, the second blade, and the connecting column. It also allows for the disassembly, replacement, and maintenance of individual first and second blades, and the increase or decrease of the area and range of the mixing blade.

[0011] Preferably, the top of the plug-in posts located symmetrically on both sides of the connecting post has a first connecting hole. The first connecting hole is a threaded hole structure and is vertically arranged. A tightening bolt is inserted into the first connecting hole, and the bottom end of the tightening bolt abuts against the top of the snap-fit ​​rod.

[0012] Preferably, hinge posts are installed on both sides of the outer end of the first blade, and a hinge cylinder is fixed to one end of the second blade.
