[0023] Embodiment:

[0024] Refer to Figures 1-4 , a cutting device for autoclaved aerated concrete blocks, including a base 1, a chute is further provided on the base 1, and a movable trolley is further provided on the chute for placing autoclaved aerated concrete blocks. And a working box 2 is fixedly connected to the base 1 through a column, and a support plate 3 is further installed in the working box 2. An electric push rod 4 is fixedly connected to the support plate 3, and a lifting block 5 is fixedly connected to the output end of the electric push rod 4. A cutting knife 501 is fixedly connected to the lifting block 5 for cutting autoclaved aerated concrete blocks. By controlling the switch of the electric push rod 4, it drives the cutting knife 501 to perform a cutting operation on the autoclaved aerated concrete blocks on the trolley.

[0025] In addition, please refer to Figure 2 and Figure 3As shown in the figure, a slidable sealing plate 201 is also installed in the working box 2. Four sealing plates 201 are spliced end to end to form a frame that slides up and down in the working box 2. A chute is provided on the support column for sliding the sealing plate 201. The sealing plate 201 is fixedly connected to the top of the lifting block 5 through a connecting rod 202. When the lifting block 5 descends, the sealing plate 201 can be moved to the base 1, thereby sealing the periphery of the bottom space of the working box 2. A pressing switch 301 is provided on the support plate 3, and the pressing switch 301 is arranged below the connecting rod 202. The pressing switch 301 is a prior art. When power needs to be turned on, the button on the pressing switch 301 needs to be touched and pressed. When power is cut off, the button on the pressing switch 301 is left.

[0026] It should be noted that two sets of symmetric air jet holes 502 are also provided on the lifting block 5, and the jet ends of the air jet holes 502 are respectively directed towards the cutting surfaces of the cutting knives 501. A negative pressure suction plate 6 is fixedly connected to the support plate 3. Negative pressure suction holes 601 are provided at the bottom of the negative pressure suction plate 6, and a flow dividing cavity is provided in the negative pressure suction plate 6, and the flow dividing cavity is communicated with the negative pressure suction holes 601. A negative pressure pump 7 and a collection box 8 are respectively fixedly installed on the support plate 3. The switch of the negative pressure pump 7 is electrically connected to the pressing switch 301, and the output end of the negative pressure pump 7 is fixedly connected to the lifting block 5 through a pipeline. A cavity is provided in the lifting block 5, and the cavity is communicated with the air jet holes 502, thereby delivering gas into the air jet holes 502.

[0027] Here, please refer to Figure 4 As shown in the figure, a filter screen 801 is also installed in the collection box 8. The collection box 8 is communicated with the input end of the negative pressure pump 7 through a pipeline, and this pipeline is arranged below the filter screen 801. The collection box 8 is fixedly connected to the negative pressure suction plate 6 through a pipeline, and this pipeline is arranged above the filter screen 801. When the negative pressure pump 7 is started, negative pressure will be generated in the collection box 8, and at the same time negative pressure will be generated in the negative pressure suction plate 6, thereby enabling the negative pressure suction holes 601 to adsorb the internal air of the working box 2, and at the same time the air will be intercepted and filtered by the filter screen 801.

[0028] The working principle is as follows. When it is necessary to cut autoclaved aerated concrete blocks, the switch of the electric push rod 4 can be started. Subsequently, the electric push rod 4 will drive the lifting block 5 to descend, and the lifting block 5 will drive the cutting knife 501 to cut the autoclaved aerated concrete blocks. When the cutting is completed, the sealing plate 201 will seal the inside of the working box 2. At this time, the connecting rod 202 contacts the pressing switch 301, thereby starting the negative pressure pump 7, making its negative pressure suction holes 601 generate suction force to adsorb the space around the bottom of the working box 2. At the same time, the air jet holes 502 will jet and blow the cutting surface of the cutting knife 501, thereby effectively removing the dust and debris on the surface of the cutting knife 501, keeping the surface of the cutting knife 501 clean, avoiding dust accumulation, and at the same time being able to reduce the wear of the cutting knife 501, extend the service life of the cutting knife 501, reduce the frequency and cost of replacing the cutting knife 501. And, the negative pressure suction holes 601 will also effectively handle the dust generated during cutting and adsorb and collect the dust in the sealed working box 2 into the collection box 8 to reduce the impact of dust on the environment and operators.
