[0031] like Figure 1The figure shows a schematic diagram of an embodiment of an aerated concrete block cutting device according to the present invention. The device comprises a chassis 15 equipped with a lower cutting blade 12, a fixed frame 6 connected to the chassis 15, a transmission mechanism mounted on the fixed frame 6 and connected to the upper cutting blade 5, and a drive mechanism for controlling the transmission mechanism. The drive mechanism comprises a drive handle 1 and a drive shaft 2 connected to the drive handle 1 and rotatably mounted on the fixed frame 6. The transmission mechanism comprises a transmission gear 3 connected to the drive shaft 2 and a transmission guide 4 meshing with the transmission gear 3. The transmission guide 4 is vertically slidably mounted within the fixed frame 6 and connected to the upper cutting blade 5. In this embodiment, the fixed frame 6 is provided with a cavity vertically configured to accommodate the transmission guide 4. The transmission guide 4 is slidably mounted within the cavity and connected to the upper cutting blade 5. In this embodiment, the lower cutting blade 12 protrudes 2 mm from the top surface of the chassis 15; in other embodiments, the height of the lower cutting blade 12 protruding from the chassis 15 can be adaptively adjusted based on the cutting effect. The upper cutting blade 5 interacts with the lower cutting blade 12 to cut the blocks at one time, reducing dust pollution. By cutting at the top and bottom of the blocks at the same time, the cutting quality can be better improved, cracking during cutting can be reduced, thereby reducing the hidden dangers of secondary cutting, improving cutting efficiency while ensuring cutting quality and cost.

[0032] In this embodiment, the fixing frame 6 is vertically connected to the top of the chassis 15, and a mounting hole 611 is provided on the fixing frame 6. The drive shaft 2 is vertically connected to the drive handle 1, and the end of the drive shaft 2 away from the drive handle 1 passes through the mounting hole 611 and is connected to the transmission gear 3. The drive shaft 2 mounted on the fixing frame 6 can not only control the rotation of the transmission gear 3, but also fix the height of the transmission gear 3, thereby playing a positioning role. In this embodiment, the drive shaft 2 is detachably connected to the drive handle. The detachable connection method facilitates local repair or maintenance and can effectively control maintenance costs. A non-slip cover that is easy to hold can also be provided on the outside of the drive handle 1 to facilitate operation and avoid wear and tear on the hands of personnel due to long-term cutting operations. The non-slip cover facilitates operation, thereby improving construction efficiency.

[0033] In this embodiment, the transmission mechanism further includes a stopper 7 , and the driving shaft 2 is slidably connected to the fixing frame 6 to adjust the distance between the transmission gear 3 and the transmission guide 4 and is fixed by the stopper 7 .

[0034] In this embodiment, the fixing frame 6 includes an adjacent adjustment frame 61 and a protective frame 62. Both the adjustment frame 61 and the protective frame 62 are vertically connected to the chassis 15, with the adjustment frame 61 positioned between the driving handle 1 and the protective frame 62. The adjustment frame 61 defines a mounting hole 611, which is a horizontally elongated hole. The protective frame 62 defines a cavity and has a hollow section on its side. The end of the drive shaft 2, distal from the driving handle 1, passes through the mounting hole 611 and the hollow section, before connecting to the transmission gear 3, which is located within the cavity of the protective frame 62. In this embodiment, the stopper 7 is detachably connected to the adjustment frame 61 by a bolt 71. When the stopper 7 is arranged in the mounting hole 611 and fixed to the adjustment frame 61 by the bolt 71, the stopper 7 fits with the drive shaft 2 to fix the distance between the transmission gear 3 and the transmission guide 4. At this time, the transmission gear 3 is engaged with the transmission guide 4. The side of the stopper 7 close to the drive shaft 2 is a curved surface adapted to the drive shaft 2 to ensure that when the stopper 7 fits with the drive shaft 2, the drive shaft 2 can also be rotated freely. By controlling the rotation of the drive shaft 2, the transmission gear 3 can be driven to rotate, and the transmission gear 3 is engaged with the transmission guide 4 to drive the upper cutting knife 5 to move along the vertical direction. When the stopper 7 is removed, the drive shaft 2 can move along the length direction of the mounting hole 611 to drive the transmission gear 3 away from the transmission guide 4. When the transmission gear 3 is disengaged from the transmission guide 4, the transmission guide 4 can be quickly moved in the vertical direction to quickly adjust the height of the upper cutting knife 5. After the height of the upper cutting knife 5 is adjusted, the stopper 7 can be inserted into the mounting hole 611 and fixed by the bolt 71. At this time, the transmission gear 3 and the transmission guide 4 are meshed again, thereby achieving rapid cutting of blocks of different thicknesses, improving cutting efficiency, and making the cutting operation of blocks of different thicknesses more flexible, with wide applicability, and conducive to promotion and use. In this embodiment, the width of the hollow area opened on the protective frame 62 is not less than the horizontal length of the mounting hole 611 to meet the horizontal movement function of the drive shaft 2. In this embodiment, a lifting ring 11 is set on the top of the transmission guide 4. The lifting ring 11 can facilitate personnel to quickly adjust the height of the transmission guide 4, which is easy to operate and can improve construction efficiency.

[0035] In this embodiment, the transmission guide 4 is slidably arranged in the cavity of the protective frame 62 and connected to the upper cutting knife 5. The sliding connection between the transmission guide 4 and the protective frame 62 can be achieved by providing a slide groove on the side of the transmission guide 4 and a slider 622 that can be embedded in the slide groove on the inner wall of the protective frame 62, so as to achieve mutual sliding connection and limitation through the adapted slide groove and slider 622; in other embodiments, the design can also be flexibly selected based on the common technical knowledge of those skilled in the art. The protective frame 62 also has a movable hole 621 in the vertical direction, and the transmission guide 4 is provided with a connecting piece, which is connected to the upper cutting knife 5 after passing through the movable hole 621. The matching slide groove and slider 622, the movable hole 621 and the connecting piece can ensure that the transmission guide 4 drives the upper cutting knife 5 to move stably, ensure the stability and safety of the device, ensure the quality of the block cutting, perform effective cutting, and improve the overall cutting quality and work efficiency.

[0036] In this embodiment, the transmission mechanism also includes a stabilizing gear 10 rotatably connected to the fixed frame 6. The stabilizing gear 10 is located below the transmission gear 3 and can also mesh with the transmission guide 4. The addition of the stabilizing gear 10 can improve the stability of the meshing transmission, and improve the stability during operation during the final stage of the upper cutting blade 5 being pressed down or the initial stage of the upper cutting blade 5 being lifted up. The stabilizing gear 10 and the transmission gear 3 work together to increase the service life of the transmission gear 3, thereby improving the stability of the aerated concrete block cutting device during use, reducing maintenance costs, and ensuring operational safety. In this embodiment, a stabilizing gear connecting rod 101 is provided on the side of the adjustment frame 61 near the protective frame 62. The stabilizing gear 10 is rotatably mounted on the stabilizing gear connecting rod 101 and is located within the cavity of the protective frame 62.

[0037] In this embodiment, the aerated concrete block cutting device further includes at least one roller 13, each of which is rotatably connected to the chassis 15, and the outer circumference of the roller 13 is no lower than the top surface of the chassis 15. In this embodiment, the rollers 13 reduce friction when the blocks move on the chassis 15, facilitating block movement, making operation convenient, improving construction efficiency, and reducing the physical effort required by operators to adjust the blocks. In this embodiment, multiple rollers 13 are provided, one on each side of the lower cutting blade 12. This not only improves the efficiency of adjusting and positioning the blocks before cutting, but also facilitates the quick and easy sliding of the two separated blocks on the chassis 1, avoiding unnecessary physical effort during operation and improving cutting efficiency. In this embodiment, the rollers 13 are rotatably connected to the interior of the chassis 15 via mounting rods. An insertion hole is provided at the top of the chassis 15, allowing the outer circumference of the rollers 13 to extend into the insertion hole and slide with the blocks.

[0038] In this embodiment, the chassis 15 is provided with a handle 17 for easy pushing / pulling. The handle 17 facilitates personnel to move the aerated concrete block cutting device, and has a simple structure and is easy to operate.

[0039] In this embodiment, the chassis 15 is provided with moving wheels 9 for movement, and the moving wheels 9 can also be used in conjunction with the handle 17 to make the device more convenient and quick to move.

[0040] In different embodiments, the chassis 15 is provided with a length mark 16 and / or an angle mark 14 to position the blocks. In this embodiment, the aerated concrete block cutting device includes both a length mark 16 and an angle mark 14. In this embodiment, it also includes a positioning rod and a length mark rod provided with a scale line to form the length mark 16. The positioning rod is connected to the chassis 15. One end of the length mark rod is rotatably connected to the chassis 15 through the positioning rod, and the other end is placed on the top of the chassis 15. In this embodiment, the length mark rod is sleeved outside the positioning rod. In this embodiment, an arc-shaped guide rail is provided on the top surface of the chassis 15 with the positioning rod as the center and the length of the length mark rod as the radius. The end of the length mark rod away from the center is provided with a plug-in that can be inserted into the guide rail; the surface of the chassis 15 is also provided with an angle disk with an angle range of 0° to 90° with the positioning rod as the center to form the angle mark 14. In this embodiment, a length rod is slidably mounted on the top of the chassis 15. The length rod and the graduated dial allow for quick positioning of the placement and angle of the blocks to be cut. When the blocks are placed, they fit snugly against the length rod for quick positioning, thereby improving cutting accuracy and efficiency. This embodiment is simple to operate, improves cutting accuracy, is easy to operate, and improves cutting efficiency.

[0041] In this embodiment, there are two fixed frames 6 and two transmission mechanisms. The two fixed frames 6 are positioned opposite each other on top of the chassis 15. The tops of the two fixed frames 6 are connected by a crossbar 8 to form a gate-shaped bracket. The drive handle 1 is positioned between the two fixed frames 6. The drive shaft 2 is positioned horizontally, with its ends passing through the corresponding fixed frames 6 and connected to the transmission gear 3. The upper cutting blade 5 is positioned horizontally between the two fixed frames 6, with its ends connected to the transmission guide 4 on the corresponding fixed frames 6. The crossbar 8 enhances the stability of the device and reinforces the fixed frames 6. The two fixed frames 6 and transmission mechanisms provide better support for the drive shaft 2, making the pressing and lifting operations of the drive handle 1 more stable and ensuring the safety of the cutting operation.

[0042] The method of using the utility model mainly includes the following steps:

[0043] The building block is placed on the chassis 15, and the driving handle 1 is lifted or pressed down to drive the transmission gear 3 to rotate. The transmission gear 3 engages with the transmission guide 4 to drive the upper cutting knife 5 to move. When the upper cutting knife 5 is pressed down, it can act in correspondence with the lower cutting knife 12 to cut the building block.

[0044] The specific working process of this embodiment is as follows:

[0045] Before cutting, the placement and angle of the block to be cut are located according to the cutting requirements and through the length mark 16 and / or angle mark 14. In this embodiment, the length mark rod can be rotated on the angle disk to position it. After positioning, the block is fitted with the length mark rod to ensure cutting accuracy. When switching to cutting blocks of different thicknesses, the stop block 7 can be first removed to adjust the disengagement of the transmission gear 3 and the transmission guide 4. When the transmission gear 3 is disengaged from the transmission guide 4, the vertical height of the transmission guide 4 can be quickly adjusted by the lifting ring 11. After the vertical height of the transmission guide 4 is initially adjusted, the stop block 7 is inserted and fixed by the bolt 71. At this time, the transmission gear 3 and the transmission guide 4 are engaged again, the driving handle 1 is pressed down and drives the transmission gear 3 to rotate. The transmission gear 3 and the transmission guide 4 are engaged and driven to drive the upper cutting knife 5 to move down quickly to cut the block. When it is necessary to cut the remaining blocks, the driving handle 1 can be lifted to drive the transmission gear 3 to rotate in the opposite direction, and then the upper cutting knife 5 is lifted to insert the next block to be cut.

[0046] When the aerated concrete block cutting device needs to be moved, the handle 17 can be pushed or pulled and the device can be quickly moved by the moving wheels 9. This is simple to operate and can reduce the physical energy consumption of the personnel when carrying. The device does not require personnel to carry the blocks when cutting, which can reduce physical energy consumption. It also has high cutting effect and good quality, does not consume electricity, and can cut blocks in one go, reducing dust pollution.
