When concrete slab's size is different, need adjust the distance between two loading boards 21, at this moment, the staff only need open second motor 94, second motor 94 drives the threaded rod 95 rather than the output shaft is fixed after the work and rotates to make slide bar 92 on two sections external screw threads be close to each other or keep away from, when the distance between two loading boards 21 matches with concrete slab, close second motor 94 can, with this make this rupture strength detection device can adapt to the needs of the concrete slab of different width sizes.

The implementation principle of the embodiment is as follows: when the flexural strength of the concrete slab is detected, a worker only needs to place the concrete slab on the two bearing plates 21 and simultaneously opens the cylinder 33, so that the piston rod of the cylinder 33 extends, the piston rod of the cylinder 33 pushes the pressing plate 34 to move downwards and contact with the concrete slab, until the concrete slab is extruded by the pressing plate 34 and breaks, the cylinder 33 is adjusted and the piston rod drives the pressing plate 34 to restore to the original position, the pressure sensor 35 records the pressure value born by the concrete slab at the moment and displays the pressure value on the display screen 11, broken slag generated in the breaking process of the concrete slab drops into the collecting shovel 2, the worker only needs to lift the collecting shovel 2 to pour the broken concrete slab and the broken concrete broken slag into the collecting box 4, the situation that the broken concrete broken slag is scattered on the supporting seat 1 is avoided, and the difficulty in cleaning the broken slag by the worker is reduced.

This scheme is when examining concrete slab's bending strength, and the staff only need place concrete slab in two loading boards 21 on, open cylinder 33 and make cylinder 33's piston rod extension for the piston rod promotes to support clamp plate 34 downstream, and until concrete slab fracture, at this moment, pressure sensor 35 records concrete slab's the biggest title pressure and shows on display screen 11. Concrete slab and concrete disintegrating slag after the fracture drop to collecting in the shovel 2 and collect, the staff only need open first motor 83, make first motor 83 drive the dwang 84 rather than the output shaft is fixed and take place to rotate, thereby it rotates and to collecting 4 lopsidedness of box to drive collection shovel 2, concrete slab and concrete disintegrating slag in the shovel 2 that until collecting drop to collecting in the box 4, the great concrete piece of volume is detained on filter screen 51, the less disintegrating slag of volume gets into and collects 4 bottoms of box, so that the staff concentrates the clearance. In the process, the buffer plate 72, the rubber plate 73 and the spring 74 all play a good buffer role, and the situation that the filter screen 51 is broken by a large concrete block is avoided. When cleaning the concrete block on the filter screen 51, the worker can open the door 53 easily and clean the concrete block only by rotating the stopper 62. When cleaning up the concrete disintegrating slag of collecting box 4 bottom, the staff only need open discharge door 43, can follow and unload out the disintegrating slag in discharge opening 41.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
