[0017] This invention features a custom-designed, graduated, arc-shaped steel plate as a rebar support, tailored to the sampling length of the rebar raw material. An adjustable, height-adjustable bracket is installed at the bottom of the arc-shaped support. Since the height of the rebar cutting machine blade varies at construction sites, the height-adjustable bracket can be adjusted in real-time according to the blade position. Since the sampling length of the rebar raw material is fixed, infrared transmitters and receivers are installed on both sides of the graduated position on the arc-shaped support to meet the specified sampling length. The receiver has a built-in wireless signal transmitter. When the rebar raw material reaches the top of the arc-shaped support through the rebar cutting machine blade, the end of the rebar pushes the sample block located on the arc-shaped support. As the plate compression return spring moves forward, when the rebar pushes the sample baffle to the marked position of the specified sampling length, the sample baffle blocks the infrared beam emitted by the infrared sensor. At this time, the infrared receiver cannot receive the infrared light, and the built-in wireless signal transmitter of the infrared receiver sends a signal to the built-in wireless signal receiver of the wireless control switch on the rebar cutter. After receiving the signal, the wireless control switch controls the rebar cutter to cut the rebar. The cut rebar is the sample specimen. After the sample specimen is removed, the return spring pushes the sample baffle back to its initial position, thus achieving the purpose of cyclic, reciprocating, and automated sampling. Throughout the sampling process, the length of the rebar specimen and the control of the rebar cutter do not require manual assistance. Therefore, the above-mentioned fully automatic rapid sampling device can quickly, accurately, and automatically solve the problem of rebar sampling on construction sites. Attached Figure Description
