A device that can adjust the water content of sand used in concrete

Abstract

The invention relates to the technical field of concrete, and discloses a device capable of adjusting the water content of concrete sand, which includes a box body, a bottom cavity is opened at the bottom of the box body, and a motor is fixedly connected to the inner bottom of the bottom cavity. The top of the motor is fixedly connected with a motor shaft, and the inner bottom of the bottom cavity is fixedly connected with a secondary gear on the right side of the motor. The bottom of the secondary gear is sleeved with a transmission belt, and the right side of the transmission belt is inserted into a screw , the top of the screw rod is movably connected with a connecting rod, the top of the connecting rod is movably connected with a slider, the left side of the slider is movably connected with a discharge door, and the inner top of the box is fixedly connected with a water spray plate. The equipment that can adjust the water content of the concrete sand, through the weight of the sand, the hopper is pressed down, and the hopper drives the transmission shaft to go down, and then the transmission shaft is used in conjunction with the primary gear, the secondary gear, and the tertiary gear, so as to achieve automatic adjustment. The effect of the moisture content of the sand.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a device capable of adjusting the water content of concrete sand. Background technique [0002] In recent years, with the acceleration of urbanization, more and more houses are being built, and concrete is becoming more and more important. Concrete generally refers to cement as a cementitious material, sand and stone as aggregates, and water (with or without addition). It is a cement concrete obtained by mixing, forming and curing according to a certain proportion, and the water content of the sand will affect the quality of the concrete and its construction performance. [0003] Generally, the sand is placed directly outside, and the water content in the sand will change with the weather. When the water content in the sand changes without changing the water ratio, the strength of the concrete will be greatly reduced, resulting in unqualified quality. When mixing concrete, wate...
