Description

Technical Field

[0001] The utility model belongs to the technical field of building mortar equipment, and in particular relates to a dry-mix mortar stirring device. Background Art

[0002] Dry mortar refers to a granular or powdery material that is physically mixed in a certain proportion of dried and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers). It is transported to the construction site in bags or bulk and can be used directly after adding water and mixing.

[0003] During the batching process, traditional bulk dry-mix mortar is transported to the construction site by a dry-powder transport truck, poured into a mortar mixing device on the construction site, and mixed with water for use. When the transmitted mortar mixing device pours the dry-mix mortar from the transport truck into the mortar mixing device, the powder in the dry-mix mortar will float and adhere to the inner wall or top of the mixing device, causing the powder to separate from the aggregate, causing the mix ratio to be destroyed, resulting in problems with the quality of the mixed mortar, thus affecting its use.

DETAILED DESCRIPTION

[0014] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0015] Embodiment: A dry-mix mortar stirring device, such as Figure 1-Figure 3As shown, it includes a mixing drum 1, wherein a guide cylinder 2 is installed inside the mixing drum 1, an upper cover 3 is installed on the top of the mixing drum 1, a material discharge hole 4 is installed on the upper cover 3, the top of the guide cylinder 2 is against the upper cover 3, the guide cylinder 2 includes a connecting ring 5 connected to the inner wall of the mixing drum 1, the lower end of the guide cylinder 2 is an inverted cone, two support frames 6 are symmetrically provided on the inner wall, a gearbox 7 is supported between the two support frames 6, a stirring motor 8 is provided on the outer cylinder wall of the guide cylinder 2, and the driving force of the stirring motor 8 is A transmission shaft 9 is connected between the driving shaft and the input shaft of the gearbox 7. A stirring shaft 10 is connected to the output shaft of the gearbox 7. The stirring shaft 10 is vertically arranged at the center of the mixing drum 1. Two groups of anti-overflow baffle groups are symmetrically arranged in the mixing drum 1 on the lower side of the installation guide cylinder 2. The two groups of anti-overflow baffle groups are symmetrically arranged on the wall of the mixing drum 1 on both sides with the stirring shaft 10. Each group of the anti-overflow baffle groups includes a plurality of anti-overflow plates 11. The anti-overflow plates 11 are arc plates with openings facing downward.
