When the device is specifically used, the opening-closing type bottom plate mechanism 1 is positioned below in an initial state, the longitudinal sliding block 13 is moved downwards by pulling the rocker arm 15, and the two transverse moving type stop blocks 7 can be close to the middle position until the two transverse moving type stop blocks are in fit contact through the linkage of the sliding control arm 12;
Then through the rotation control of the lifting screw rod 16, the whole opening-closing type bottom plate mechanism 1 can be lifted, in the lifting process, the lifting screw rod 16 can rotate with the chute gear 29, the rotation motion of the lifting screw rod 16 relative to the chute gear 29 can drive the chute gear 29 to rotate (similar to a worm gear transmission mechanism), the transmission ratio is A, the lifting motion of the chute gear 29 relative to the lifting screw rod 16 can also drive the chute gear 29 to rotate (similar to a rack-and-pinion transmission mechanism), the transmission ratio is B, in actual use, the actual transmission ratio between the lifting screw rod 16 and the chute gear 29 is superposition of A and B because the rotation of the lifting screw rod 16 can drive the opening-closing type bottom plate mechanism 1 to lift, the transmission matching precision between the lifting screw rod 16 and the chute gear 29 is not high, and the existence of a space is permitted, as long as the space quantity can be driven to rotate the chute gear 29.
When the open-close type bottom plate mechanism 1 ascends, the chute gear 29 carries the driven rotating shaft 27 and the spur gear 28 to rotate, the spur gear 28 pushes the rack body 25 to slide upwards along the rack guide rail 24, at the moment, the flexible steel plate 22 gradually stretches out under the elastic force of the reset spring 23, as the middle position of a workpiece is blocked by the top opening of the shell 19, the end slope of the flexible steel plate 22 can be smoothly inserted into the bottom of a test block and separate the end slope from the bottom between the test block and the transverse type stop 7, and the top opening of the shell 19 is provided with a downward bending gradient, so that crushed slag which is crushed later can slide onto the flexible steel plate 22 through the slope even if a small part of slag falls above the shell 19.

After the test is finished, the longitudinal sliding block 13 is pushed upwards through the rocker arm 15, and at the moment, the transverse moving type stop block 7 transversely moves outwards and is separated under the linkage of the sliding control arm 12, so that a space for the broken slag to fall is reserved;
Then the whole body of the open-close type bottom plate mechanism 1 is lowered by the reverse rotation of the lifting screw rod 16, and the rotation direction of the chute gear 29 is opposite to that of the lifting;
when the chute gear 29 rotates, the rack body 25 can be driven to descend through the spur gear 28, meanwhile, the flexible steel plate 22 can be retracted in a sliding manner, meanwhile, the rolling brush rotating shaft 33 and the rolling brush cylinder 34 can also rotate simultaneously through the linkage of the linkage rope 32, and the rotating direction of the rolling brush cylinder 34 has the effect of pushing the slag accumulated on the flexible steel plate 22 outwards so as to avoid the slag from being adhered to the flexible steel plate 22.
When the rolling brush is lowered, the rotation of the rolling brush rotating shaft 33 deforms the torsion spring and accumulates elastic force, so that the rolling brush rotating shaft 33 can rotate and reset and keep the tension of the linkage rope 32 in the raising stage.
In the retracting process of the flexible steel plate 22, firstly, the slag moves along with the flexible steel plate 22 and is accumulated at a position close to the rolling brush cylinder 34, and in the final retracting stage of the flexible steel plate 22, namely, when the opening-closing type bottom plate mechanism 1 is lowered to a lower position, the slag can fall from the flexible steel plate 22 towards the tray 37, and the fallen slag falls into the tray 37 to be cleaned timely.
