Under the guiding action of the guide rail 312 and the guide groove 221, the pressing block 220 and the dust cover 310 are not easy to deviate, the probability that the dust cover 310 is clamped on the pressing block 220 is reduced, and the probability that the dust cover 310 is crushed by the pressing block 220 is further reduced. And the rubber sheet 222 is arranged, so that the guide rail 312 can be wiped once when the pressing block 220 presses the cement test block each time, the sliding precision of the dust cover 310 is improved, and the probability of crushing the dust cover 310 is reduced. The cross section of the guide rail 312 is isosceles triangle, so that the broken slag is easily removed after being adhered to the guide rail, and the rubber sheet 222 can conveniently scrape the broken cement slag on the guide rail 312.
Referring to fig. 2 and 3, the dust-proof mechanism 300 further includes a blower 320 for cleaning the slag, a storage tank 330, and an air pipe 340. The storage box 330 is detachably and fixedly connected to the rack 100 by screws, and the fan 320 is fixedly connected to the rack 100 or the storage box 330 by bolts or other suitable positions for placing the fan 320. An air inlet end of the blower 320 communicates with the inside of the dust cover 310 through an air pipe 340, and an air outlet end of the blower 320 communicates with the storage tank 330.
Referring to fig. 2 and 3, while the hydraulic cylinder 210 presses the cement test block or after the cement test block is crushed, the fan 320 is started, and then the crushed slag and dust generated when the cement test block is crushed are sucked into the air pipe 340, and the dust and the crushed slag pass through the fan 320 and enter the storage tank 330 under the guidance of the air pipe 340. And after the dust in the dust cover 310 is cleaned, the piston rod of the hydraulic cylinder 210 is retracted, so that the dust in the dust cover 310 is not easy to float to the piston rod of the hydraulic cylinder 210, and the abrasion of the piston rod is reduced. Since the dust cover 310 is moved up and down continuously, the air tube 340 is provided as a flexible tube, for example, the air tube 340 may be a rubber tube or a bellows tube.
Referring to fig. 3, the dust cover 310 is provided with an air inlet hole 313, and the air inlet hole 313 and the air pipe 340 are respectively disposed on two opposite end surfaces of the dust cover 310. The dust cover 310 is screwed with a filter net 314, and the filter net 314 is placed in the air inlet hole 313 in a filling manner.
When the blower 320 is turned on, air outside the dust boot 310 can enter the dust boot 310 through the air inlet holes 313, and the air inside the dust boot 310 is caused to flow, so that the air can entrain dust and debris into the storage box 330. Due to the arrangement of the filter screen 314, the broken slag generated when the cement test block is broken is not easy to splash out of the dust cover 310 from the air inlet hole 313, and the abrasion of the piston rod is reduced.
