The invention provides a
system for automatic detection of
moisture content of concrete aggregate. The
system comprises a material taking
assembly, a material container, a
drying assembly, a weighingassembly and a
control circuit, wherein the material taking
assembly comprises a mounting frame, two slide rails, two mounting rods, a first spring, a first cylinder, a push plate, a
shovel and a mounting mechanism, wherein the mounting frame is erected on the ground, the two slide rails which are mutually parallel are mounted on the mounting frame, one mounting rod capable of sliding under the guide of each slide rail is mounted on each slide rail, the two mounting rods are positioned in a vertical direction, and the
shovel is arranged between the two mounting rods; the material container ispositioned below the
shovel close to the first cylinder; the
drying assembly is used for
drying aggregate in the material container; the weighing assembly is used for supporting the material container; and both the first cylinder and the weighing assembly are connected with the
control circuit. The
system for automatic detection of the
moisture content of the concrete aggregate solves the problemin the prior art that the aggregate at the middle part of a conveying belt can not be taken because only the aggregate at the
discharge end of a feeding belt can be taken.
