[0015] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0016] 1. The sliding track and track groove allow the support platform to slide on the bottom cutting table, facilitating quick adjustment of the position of the support platform and the aerated concrete blocks placed inside. The alignment scale and marker pointer can move the marker pointer as the support platform moves, and the alignment scale can be used to accurately position the cutting position of the aerated concrete blocks, ensuring the dimensional accuracy of the aerated concrete blocks after subsequent cutting.

It also ensures that the dimensions of the aerated concrete blocks after cutting do not match the actual masonry dimensions, guaranteeing that the aerated concrete blocks can be accurately cut and used in masonry.

[0020] 3. By evenly opening through slots at the bottom of the support platform, the debris generated during the cutting of the aerated concrete block can fall into the through slots between the two cutting support bars. With the help of the collection slot and collection hopper, the debris is easily transported into the collection box under its own weight. The debris is then collected by the sliding box, thus effectively collecting the debris generated after the aerated concrete block is cut under pressure, preventing debris from overflowing and affecting the construction environment. At the same time, the sliding box is connected to the inside of the collection box by sliding, which facilitates the disassembly of the sliding box for cleaning the debris collected inside the sliding box.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] Example: Figure 1-5 As shown, this utility model provides a technical solution, a device for cutting aerated concrete blocks quickly and accurately without dust, including a bottom cutting table 1. The top four corners of the bottom cutting table 1 are detachably connected to a top frame 3 through connecting square tubes 2. A hydraulic cylinder 4 is installed in the middle of the inner side of the top frame 3. A cutting blade holder 5 is fixedly connected to the bottom telescopic end of the hydraulic cylinder 4, and a cutting pressure blade 6 is fixedly installed at the bottom end of the cutting blade holder 5.

[0031] The top two sides of the bottom cutting table 1 are symmetrically connected with sliding rails 7. The support table 8 is slidably connected to the sliding rails 7. The bottom of the support table 8 is slidably connected to the sliding rails 7 through the rail grooves 9. Several sets of cutting support bars 10 are installed at equal intervals on the inner bottom of the support table 8. The top of the cutting support bar 10 is provided with a pointed protrusion. The cutting pressure knife 6 is arranged parallel to the cutting support bar 10. The length of the cutting pressure knife 6 is less than the length of the cutting support bar 10. The cutting support bar 10 can be used to cooperate with the cutting pressure knife 6 to stably cut the gas block. At the same time, the cutting pressure knife 6 can extend to the inner side of the support table 8.

[0032] A limiting plate 11 is fixedly installed on one side of the support platform 8, and a limiting bolt 12 is connected to the inner side of the limiting plate 11. A fixing groove 13 is provided on the top of the bottom cutting table 1 corresponding to the limiting bolt 12. One end of the sliding rail 7 is connected to a limiting seat. The bottom end of the limiting plate 11 slides along the top surface of the bottom cutting table 1. The limiting bolt 12 is connected to the inner side of the fixing groove 13, which facilitates the restriction of the sliding position of the support platform 8, so that the support platform 8 can move with the air block within the cutting range at the bottom of the cutting pressure knife 6. At the same time, through the limiting plate 11, the limiting bolt 12 and the fixing groove 13, the position of the support platform 8 can be locked and restricted after the support platform 8 moves the air block to the designated position. An alignment scale line 14 is provided on the side of the top surface of the bottom cutting table 1 opposite to the fixing groove 13. A marking pointer 15 corresponding to the position of the alignment scale line 14 is provided on the edge of the support platform 8. A horizontal ray lamp 16 is fixedly installed in the middle of the cutting knife holder 5. The horizontal ray lamp 16 is powered by a built-in battery.

[0033] Connecting rods 17 are fixedly welded to the top four corners of the bottom cutting table 1 and the bottom four corners of the top frame 3. The inside of the connecting square tube 2 is provided with an assembly groove 18. The connecting rods 17 fit into the inside of the assembly groove 18. Fixing bolts 19 are installed on the edge of the connecting square tube 2. The bottom cutting table 1 and the top frame 3 are assembled and connected to the connecting square tube 2 through the connecting rods 17. The fixing bolts 19 pass through the connecting square tube 2 and are connected to the inside of the connecting rods 17 by threads. The connecting rods 17 facilitate the quick assembly and connection between the bottom cutting table 1 and the top frame 3. The fixing bolts 19 ensure the stability of the connecting rods 17 and the connecting square tube 2 after connection.

[0034] The top of the hydraulic cylinder 4 is mounted on the inside of the top frame 3 via a cross, and the edge of the cross is detachably connected to the top frame 3 via a mounting ear plate 20.

[0035] A through groove 21 is provided at the bottom end of the support platform 8 between two adjacent cutting support bars 10. A collection groove 22 is provided at the bottom of the bottom cutting platform 1. A collection hopper 23 is connected to the bottom of the bottom cutting platform 1 corresponding to the collection groove 22. A collection box 24 is fixedly installed at the bottom end of the collection hopper 23, and a sliding box 25 is slidably connected to the inner side of the collection box 24. The collection groove 22 is located at the middle of the bottom of the bottom cutting platform 1. The bottom discharge end of the collection groove 22 is connected to the top feed end of the collection hopper 23. The bottom of the collection hopper 23 is connected to the inside of the collection box 24. Through the collection groove 22 and the collection hopper 23, combined with the weight of the debris, the debris is conveniently further concentrated and transported to the sliding box 25 inside the collection box 24.

[0036] The working principle and usage process of this utility model: In the actual application of this dust-free, fast and accurate aerated concrete block cutting device, after the cutting device is transported to the aerated concrete block construction site, it needs to be assembled. Connecting rods 17 are set at the ends of the bottom cutting table 1 and the top frame 3 respectively, so that the bottom cutting table 1 and the top frame 3 can be quickly assembled and connected through the connecting rods 17 and the internal assembly groove 18 of the connecting square tube 2. After the connecting rods 17 and the connecting square tube 2 are assembled, the connecting rods 17 and the connecting square tube 2 are stabilized by fixing bolts 19.

[0037] After the bottom cutting table 1 and the top frame 3 are initially assembled, the hydraulic cylinder 4 and its bottom cutting mechanism are combined and connected to the top frame 3 by installing the ear plate 20. This facilitates quick assembly to form the main structure of the cutting device, making it easy to assemble and install the device and convenient to transport. This allows the cutting device to be transported to the construction site more easily, reducing the difficulty of transportation and avoiding discrepancies between the cutting position and the masonry position of the aerated concrete block, which would cause the size of the aerated concrete block after cutting to differ from the actual masonry size. This ensures that the aerated concrete block can be accurately cut and used for masonry.

[0038] In the specific process of cutting the aerated concrete block, the aerated concrete block is first placed inside the support platform 8. The sliding rail 7 and the rail groove 9 facilitate the sliding connection of the support platform 8 and make it easy to adjust the position of the aerated concrete block placed inside the support platform 8. At the same time, when the support platform 8 moves, it will drive the marker pointer 15 to move synchronously. The alignment scale line 14 is used to accurately position the cutting position of the aerated concrete block, ensuring that the aerated concrete block after cutting has higher dimensional accuracy. After the support platform 8 moves the aerated concrete block to the designated cutting position, the position of the support platform 8 is restricted by the limiting plate 11, the limiting bolt 12 and the fixing groove 13, so that the position of the support platform 8 will not move when the aerated concrete block is cut, ensuring the stability of the aerated concrete block during cutting.

[0039] Before starting the hydraulic cylinder 4 to cut, the horizontal ray lamp 16 at the cutting pressure knife 6 can be used to further check the cutting position of the air block before cutting, so as to further ensure the cutting accuracy of the air block. During cutting, the hydraulic cylinder 4 drives the cutting knife seat 5 and the cutting pressure knife 6 to move. The pressure of the cutting pressure knife 6 is used to squeeze the air block. The cutting support bar 10 is used to cooperate with the cutting pressure knife 6 to achieve stable cutting of the air block.

[0040] When the aerated concrete block is cut, the bottom of the support platform 8 is evenly provided with through grooves 21, so that the debris generated during the cutting process can fall into the through grooves 21 through the two cutting support bars 10. With the help of the collection groove 22 and the collection hopper 23, the debris is further concentrated and transported to the sliding box 25 inside the collection box 24 under the action of the debris's own gravity, so as to collect the debris generated after the aerated concrete block is cut under pressure in a concentrated and effective manner.

[0041] In addition, the sliding box 25 is connected to the inside of the collection box 24 by sliding to clean the debris collected inside the sliding box 25. After cutting, the cutting device is disassembled into multiple components to facilitate easy handling of the device, making the cutting device easier to transport and reducing the difficulty of its transfer.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
