Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a concrete block cutting device. Background Technology

[0002] Utility model patent CN210939944U discloses a concrete block cutting device. It employs left and right push-pull devices to move the concrete blocks, eliminating the need for manual pushing by the worker. A blade guard effectively prevents the blocks from being touched by the serrated cutting blade during the pushing process, thus protecting worker safety. This utility model features a stable worktable composed of a left blocking protrusion, a central cutting notch, a right blocking protrusion, a right horizontal sliding groove, a left horizontal sliding groove, and a worktable surface. The left and right horizontal sliding grooves engage the moving slider and the bottom slider of the right push-pull device, allowing the left and right push-pull devices to move within these grooves. The left and right blocking protrusions further prevent the blade guard from contacting the serrated cutting blade, thus protecting worker safety during concrete block cutting. However, this device is not convenient for multi-directional adjustment and cutting of the blocks, and the dust generated during cutting is difficult to manage. Utility Model Content

By rotating the tray, the orientation of the block changes. The screw and support then move in a threaded motion, causing the pressure block to move and press against the slide cylinder, thus limiting the tray's position. This ensures precise positioning of the block after adjustment, making it easier to adjust the cutting direction. The dust collection mechanism includes a corrugated sleeve bonded to a support frame. A counterweight ring is bonded to the lower end of the corrugated sleeve. A filter cartridge is detachably installed inside the support frame, and an air pump is fixedly installed at the upper end of the filter cartridge.

[0017] Please see Figure 1 , Figure 3 , Figure 4 The adjusting mechanism 6 includes a support shaft 61. The upper end of the slide plate 2 is mounted on the support shaft 61 via a bearing. A tray 62 is fixedly connected to the upper end of the support shaft 61. A slide cylinder 63 is slidably connected to the outer side of the support shaft 61. A tooth 64 is welded to the lower end of the slide cylinder 63. The tooth 64 is slidably connected to the slide plate 2. A spring 65 is provided on the outer side of the support shaft 61. One end of the spring 65 contacts the slide plate 2, and the other end of the spring 65 contacts the slide cylinder 63. By providing the spring 65, the slide cylinder 63 can be easily reset. A support 66 is welded to the upper end of the slide plate 2. The support 66 contacts the tray 62, and the interior of the support 66 is connected by threads. A lead screw 67 is provided, and a pressure block 68 is mounted on the outer side of the lead screw 67 via a bearing. The pressure block 68 contacts the slide cylinder 63. The movement of the pressure block 68 is controlled by the lead screw 67. A slide seat 69 is slidably connected inside the tray 62. A support block 610 is fixedly installed at the upper end of the slide seat 69. An adjusting rod 611 is threadedly connected inside the support block 610. By rotating the tray 62, the orientation of the block changes. By rotating the lead screw 67 and the support 66 to make threaded movements, the pressure block 68 moves and presses and limits the slide cylinder 63, thereby limiting the tray 62. This makes the positioning of the block after adjustment accurate, and makes it more convenient to adjust and cut the block.

[0018] Please see Figure 1 , Figure 2 , Figure 3 The dust collection mechanism 9 includes a corrugated sleeve 91, which is bonded to the support 7. A counterweight ring 92 is bonded to the lower end of the corrugated sleeve 91. A filter cartridge 93 is detachably installed inside the support 7. An air pump 94 is fixedly installed at the upper end of the filter cartridge 93. The counterweight ring 92 on the corrugated sleeve 91 contacts the block to seal the cutting area. The air pump 94 draws in the dust generated during cutting, allowing it to enter the filter cartridge 93 for dust collection and treatment, thus preventing dust from scattering.

[0019] Working principle: In use, the block is placed on the tray 62, and the sliding block 69 slides on the outside of the tray 62. The sliding block 69 drives the support block 610 to move, which in turn moves the adjusting rod 611 to adjust its position. Then, rotating the adjusting rod 611 and the support block 610 causes a threaded movement, which moves the adjusting rod 611 towards the block, thus limiting the block's position. Then, according to the desired cutting position of the block, manually rotating the screw 67 and the support 66 causes a threaded movement, which moves the pressure block 68. This causes the slide cylinder 63 to move upward under the elastic action of the spring 65, disengaging the insert tooth 64 from the slide plate 2. Then, rotating the tray 62 changes the block's position. Then, reversing the adjusting rod 611 resets the pressure block 68, thus limiting the tray 62 and the block. By rotating the tray 62, the block's position can be adjusted. The block's orientation changes, and the screw 67 and support 66 rotate in a threaded motion, causing the pressure block 68 to move and press against the slide cylinder 63, thus limiting the tray 62. This ensures precise positioning of the block after orientation adjustment, making it easier to adjust the cutting orientation. Then, the saw wheel 8 and motor 4 are started. Motor 4 drives the screw 5 to rotate, and the screw 5 rotates in a threaded motion with the slide rod 3, causing the slide plate 2 to move. When the block contacts the saw wheel 8, the saw wheel 8 cuts the block. Then, the air pump 94 is started, and the air pump 94 draws air from the filter cartridge 93, causing the filter cartridge 93 to collect dust. The counterweight ring 92 on the corrugated sleeve 91 contacts the block, sealing the cut area. The air pump 94 draws in the dust generated during cutting, allowing it to enter the filter cartridge 93 for collection and treatment, preventing dust spillage.
