DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely explained below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] like Figure 1-3As shown, a coal mine silo truck loading box positioning device includes a loading platform 1, an N-shaped frame 2 is fixed to the top front end of the loading platform 1 by screws, a PLC control cabinet 3 and a storage silo 4 are provided on the N-shaped frame 2, the PLC control cabinet 3 is fixed to the lower left side of the N-shaped frame 2 by screws, the storage silo 4 is fixed to the middle of the top of the N-shaped frame 2 by screws, and an electric discharge valve 5 is fixed to the discharge port at the bottom of the storage silo 4 by screws, a support seat 6 is symmetrically fixed to the front and rear ends of the left side of the top of the loading platform 1 by screws, and an axle seat 7 is symmetrically fixed to the front and rear ends of the right side of the top of the loading platform 1 by screws, a transmission motor 8 and a transmission screw 9 are provided on the axle seat 7, and the transmission motor 8 is fixed by screws. It is installed and fixed on the upper outer side of the shaft seat 7 at the rear end, the transmission screw 9 is rotatably connected to the upper inner side of the shaft seat 7, and the rear end of the transmission screw 9 is fixedly connected to the main shaft of the transmission motor 8 by screws, and a guide shaft 10 is fixed to the upper inner side of the support seat 6 by screws. A transmission frame 11 is mounted on the guide shaft 10, and the right side of the transmission frame 11 is threadedly connected to the transmission screw 9 by threads. A guide plate 12 is fixed to the inner side of the top of the transmission frame 11 by screws, and a support rod 13 is fixed to the middle of the rear end of the transmission frame 11 by screws. A grating sensor 14 is fixed to the rear end of the support rod 13 by screws, and the PLC control cabinet 3 is electrically connected to the electric discharge valve 5, the transmission motor 8, and the grating sensor 14 through wires.
