Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction equipment, and in particular to a material-saving and splashing-preventing material distribution machine. BACKGROUND

[0002] In recent years, China has vigorously promoted the development of green buildings, and many current residences are multi-story residences with a height of 3m and a basement. Except for the elevator antechamber, the remaining negative one-story wall columns of the basement peripheral building are outside the basement outer wall, and there is a ground beam without a structural plate. In order to ensure the construction period, the method of adding a structural plate to the first floor and adding a retaining wall to the periphery of the negative one-story wall column in the later stage is used to save the time consumed by the basement outer wall waterproofing and the core soil backfilling construction, thereby ensuring the construction period node. During the pouring process of the interlayer beam concrete and the first floor structural plate concrete, the traditional concrete pouring method of ground pump + material distribution machine is used. The conventional material distribution machine pouring interlayer beam (without concrete plate structure) will have the following problems:

[0003] (1) The number of interlayer beams is large, and the concrete volume is small, which will inevitably frequently pause the feeding. The sending of the pause feeding signal to the receiving signal will have a reaction time period, and the excess concrete will be generated in this time period. The excess concrete cannot be utilized, resulting in waste of concrete.

[0004] (2) The concrete pouring adopts a ground pump to transport concrete material, and the concrete material has a high speed and uneven volume. During the pouring process of a small beam width concrete beam, the splashing and falling of concrete will be inevitably caused, resulting in waste of materials and pollution of the ground.
