[0016] The device for measuring the moisture content of aggregate in the concrete mixing plant is equipped with a rear fixing frame, a stepping gear, a fixed rack, and a movable rack. When the device is used to detect the moisture content of concrete aggregate, the operator first needs to movably connect the movable rack to an external support structure to make it move flexibly. Then, the operator controls the electric cylinder, the motor, and the concrete moisture content measuring instrument through the control panel. After the electric cylinder is started, the rear fixing frame is pushed by the push rod. The rear fixing frame clamps the stepping gear and drives it to rotate around the center of the middle part of the rear fixing frame. The stepping gear moves on the fixed rack through the meshing of the tooth grooves. At this time, the movable rack meshed with the upper end of the stepping gear is driven and slowly moves forward according to the rotation of the stepping gear until the front end of the concrete moisture content measuring instrument touches the aggregate. At this time, the concrete moisture content measuring instrument detects the moisture content of the concrete aggregate and transmits the data to the control panel for the operator to read. After the moisture content of the concrete aggregate in a single direction is detected, the operator can control the motor to drive the driven gear through the driving gear, so that the driven gear rotates slowly. At this time, the connected concrete moisture content measuring instrument also rotates with the driven gear, so that the front end of the concrete moisture content measuring instrument touches the concrete aggregate at different positions and measures multiple groups of data for the operator to read. Through the above settings and processes, the device can not only improve the automation degree of detecting the moisture content of concrete aggregate, but also adjust the measuring direction to measure the moisture content data of concrete aggregate at different positions, greatly improving the accuracy of the data.

The fixed rack 502 is fixedly installed on the upper end face of the mounting base 1, and the tooth grooves are meshed with the stepping gear 501.
[0026] In this embodiment, the rear-end fixing frame 5 is integrally in a clamp-like structure, sandwiching both sides of the stepping gear 501, and a bearing structure is arranged at the connection positions of both ends with the stepping gear 501; The active rack 6 further includes a motor 601, a driving gear 602, and a driven gear 603.

The driving gear 602 is movably connected to the motor 601, and the driven gear 603 is movably connected to the top of the active rack 6;
[0027] Specifically, the bearing structures arranged at the connection positions of both ends of the stepping gear 501 and the rear-end fixing frame 5 can make the stepping gear 501 rotate more smoothly and not easily fall off;
[0028] In this embodiment, the tooth grooves of the driven gear 603 and the driving gear 602 are meshed with each other, and a shaft structure is arranged at the connection position of the bottom of the driven gear 603 and the active rack 6 and is embedded in the interior of the active rack 6; The active rack 6 needs to be pre-connected to an external support structure before the overall operation of the device to ensure that the active rack 6 is supported and has a movable range;
