Technical Field
[0001] The utility model relates to the technical field of concrete block cutting, in particular to an aerated concrete block cutting machine. Background Art
[0002] Aerated concrete blocks are an excellent new type of building material that is lightweight, porous, heat-insulating, fire-resistant, can be nailed, sawed, planed, and has a certain degree of earthquake resistance. They also have the advantages of environmental protection, so they are widely used in high-rise frame structure buildings.
[0003] During the production process, aerated concrete blocks need to be cut into blocks of different sizes according to the needs of house buyers to meet the needs of building construction. A cutting machine is required when cutting aerated concrete blocks. During the cutting process, a large amount of dust will be generated at the contact point between the cutting tool and the concrete block. In order to reduce the impact of dust on the environment, the cutting machine is generally equipped with a dust reduction device for dust removal and reduction.
[0004] The Chinese invention patent with patent application number CN202310891454.1 records a cutting machine for processing aerated concrete blocks, which sprays water toward the cutting position through a nozzle, which is beneficial to dust reduction treatment for debris scattered into the air during cutting. At the same time, the cooperation of the opening and closing components automatically realizes water outlet from the connecting pipe during cutting, avoiding wasting water resources by starting when not cutting. However, the above device only sprays water to the cutting position through a nozzle to reduce dust, which makes it difficult to settle all the dust. Dust will still float around, polluting the surrounding environment and threatening the health of the workers. Utility Model Content
[0005] The purpose of the present application is to provide an aerated concrete block cutting machine to solve the problem in the above-mentioned background technology that only spraying water to the cutting area to reduce dust is difficult to settle all the dust, and some dust will still float around, thereby polluting the surrounding environment and threatening the health of the workers.
[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an aerated concrete block cutting machine, comprising a base plate, a placing plate movably provided on the base plate, a cutting box fixedly connected to the top of the base plate, two first hydraulic cylinders symmetrically fixedly connected to the top wall of the cutting box, the output ends of the two first hydraulic cylinders are provided with lateral movement components, a cutting knife is installed on the lateral movement component, two groups of transverse pipes are symmetrically fixedly connected to the top of the cutting box, a plurality of atomizing nozzles are equidistantly connected to the bottom of the transverse pipes, two water inlet pipes are symmetrically connected to the top of the transverse pipes, the top ends of the two water inlet pipes pass through the top wall of the cutting box and extend to the upper side thereof, and two drainage pipes are symmetrically connected to the front and rear sides of the cutting box.
[0007] Preferably, it also includes an auxiliary dust reduction component for enhancing the dust reduction effect, the auxiliary dust reduction component includes two groups of dust attachment plates symmetrically connected to the top wall of the cutting box through a first rotating axis, the number of dust attachment plates in each group is equal to the number of transverse tubes in each group, and the two groups of multiple dust attachment plates and the two groups of multiple transverse tubes are alternately distributed, and the auxiliary dust reduction component also includes a swing unit for driving the dust attachment plate to swing. The advantage of such a setting is that the dust attachment plate is driven to swing back and forth by the swing unit, so that the dust attachment plate can fully contact with the floating dust, and then cooperate with the atomizing nozzle to spray water mist on the surface of the dust attachment plate, so that the dust attachment plate can absorb the floating dust, and then as the amount of water on the dust attachment plate gradually increases, the dust will be mixed in the water and fall to the bottom of the cutting box and discharged through the drain pipe, which can effectively enhance the adsorption and dust reduction effect of the floating dust.
[0008] Preferably, the front and rear ends of the first rotating shaft respectively pass through the front and rear inner walls of the cutting box and extend to the front and rear sides of the cutting box, the swing unit includes a lever symmetrically fixedly connected to the front and rear ends of the first rotating shaft, and two first torsion springs are symmetrically fixedly connected between the sides close to each other and the front and rear sides of the cutting box, and the swing unit also includes two groups of cylinders symmetrically fixedly connected to the front and rear sides of the cutting box, and two push plates are symmetrically fixedly connected to the output ends of the two groups of cylinders, and two groups of vertical plates are symmetrically fixedly connected to the tops of the two push plates, and the number of vertical plates in each group is equal to the number of first rotating shafts in each group, and each group of vertical plates can respectively conflict with the bottom of each group of levers. The advantage of such a setting is that the lever is driven to swing back and forth up and down by pushing the vertical plates by the cylinders, so that the dust plate can swing back and forth in the direction close to the cutting knife or away from the cutting knife, so that the dust plate can better absorb dust floating from the cutting knife, effectively improving the dust reduction effect.
[0009] Preferably, the swing unit also includes two groups of baffles symmetrically fixedly connected to the front and rear sides of the cutting box, the two groups of baffles correspond to two groups of levers respectively and the two can conflict with each other, the swing unit also includes a top plate rotatably connected to the top of the vertical plate through the second rotating shaft and the second torsion spring, the top of the top plate can conflict with the bottom of the lever. The advantage of such a setting is that when the top plate moves upward to the moving height, the lever will disengage from the top plate. At this time, the lever will rotate downward and reset under the elastic force of the first torsion spring, and then the lever will collide with the baffle and stop rotating immediately, so that the mud and water attached to the dust plate are dropped due to inertia, thereby accelerating the falling speed of the mud and water on the dust plate, thereby improving the efficiency of the dust plate in absorbing and reducing dust.
[0010] Preferably, a buffer sleeve is fixedly sleeved on the outer peripheral surface of the blocking rod. The advantage of such an arrangement is that the impact force on the shifting rod can be reduced, and the shifting rod can be protected to work normally for a long time.

[0012] In summary, the technical effects and advantages of the utility model are:
[0013] In the utility model, multiple groups of atomizing nozzles are arranged to spray water mist evenly into the interior of the cutting box, so that the dust generated by the cutting knife when cutting aerated concrete blocks can contact and mix with the water mist and fall to the bottom of the cutting box and be discharged through the drain pipe, thereby effectively preventing dust from floating and polluting the surrounding environment, and effectively improving the dust reduction and dust removal effect.
[0014] In the utility model, the dust attaching plate is driven to swing back and forth by the swinging unit, so that the dust attaching plate can fully contact with the dust floating in the cutting box. At the same time, since the water mist adheres to the surface of the dust attaching plate, the dust contacted by the dust attaching plate when swinging will mix with the water mist on the surface of the dust attaching plate to form muddy water. Then, as the atomizing nozzle continuously sprays water mist on the surface of the dust attaching plate, the muddy water on the surface of the dust attaching plate will fall to the bottom of the cutting box under the action of gravity, thereby further improving the dust removal and dust reduction effect on the floating dust.
