TECHNICAL FIELD
[0001] The application relates to the technical field of concrete production, in particular to a three-dimensional concrete feeding system. BACKGROUND
[0002] With the continuous progress of society, various buildings are also being continuously built, and a large amount of concrete is usually needed in the construction site of the building. At present, the main source of concrete in the construction site is transportation by a concrete mixer truck and on-site mixing by a concrete mixer. In some construction sites with poor terrain, the concrete mixer truck cannot be smoothly transported, and therefore, a vertical flat-mouth mixer is needed to mix the concrete on site. When the vertical flat-mouth mixer is used to mix the concrete, sand and stone aggregates and other raw materials need to be added into the vertical flat-mouth mixer. Since the vertical flat-mouth mixer is relatively high and the feeding port is usually arranged at the top end of the vertical flat-mouth mixer, a feeding system is usually arranged beside the vertical flat-mouth feeding machine to facilitate the feeding of the sand and stone aggregates. At present, the feeding system is usually a conveying belt arranged beside the vertical flat-mouth mixer at an inclination, and the conveying belt is used to feed the sand and stone aggregates.
[0003] According to the related technology in the above, the inventor believes that since the installation inclination of the conveying belt is too large, the conveying of the sand and stone aggregates is affected, and therefore, the installation inclination of the conveying belt is usually not too large, so that more than two conveying belts need to be used to realize the feeding of the sand and stone aggregates, and therefore, the feeding system usually occupies a large space. Therefore, there is room for improvement. CONTENT OF THE UTILITY MODEL
