[0002] Autoclaved aerated concrete (AAC) is a lightweight porous silicate product made primarily from siliceous materials (sand, fly ash, and silica-containing tailings) and calcareous materials (lime and cement), with the addition of a foaming agent (aluminum powder). It is produced through processes such as batching, mixing, pouring, pre-curing, cutting, autoclaving, and maintenance. Because it contains a large number of uniform and fine pores after aeration, it is named autoclaved concrete. Publication number CN217123590U discloses an AAC block grooving device. This device uses an upper and lower semi-disc that are engaged and connected via a slot and a fixing plate. A first and second ring clamp and fix the two sides of the upper and lower semi-discs, facilitating the assembly of the cutting blade onto the outer wall of the shaft. Bolts are threaded through the through-slot and threaded groove for easy disassembly and installation of the cutting blade, allowing for easy replacement of severely worn blades, extending the device's service life, and improving its practicality.

[0003] Although the device makes it easy to assemble and disassemble the cutting blade, in actual use, when it is necessary to groove different parts of the concrete block, the cutting blade needs to be disassembled and reinstalled to the designated position, or the position of the concrete block needs to be adjusted. The operation process is cumbersome, the cutting efficiency is low, and the safety of use is low.

[0004] Therefore, it is necessary to invent a slotting device for aerated concrete blocks to solve the above problems. Utility Model Content

An adjustment assembly is provided inside the equipment housing, comprising a first motor, a precision screw, a linear guide rail, a transmission block, a linear bearing, a limit block, a mounting plate, a second motor, and a cutting blade.

[0007] By adopting the above technical solution, the second motor drives the cutting blade to rotate, while the hydraulic cylinder pushes the equipment shell downward, thereby pushing the cutting blade downward to groove the concrete block. When the position of the cutting blade needs to be adjusted, the first motor, precision screw, linear guide rail, transmission block and linear bearing work together to adjust the position of the mounting plate, thereby adjusting the position of the cutting blade, improving the convenience of adjusting the cutting blade.

[0008] Optionally, two sets of limiting rods are fixedly connected to the front and rear surfaces of the equipment housing, and the end of the limiting rod facing away from the equipment housing is slidably connected to the support rod.

[0014] Optionally, the lower surface of the equipment housing is provided with two sets of limiting grooves, and each of the two sets of limiting grooves is slidably connected to a limiting block. The upper ends of the two sets of limiting blocks are respectively fixedly connected to two sets of linear bearings, and the lower ends of the two sets of limiting blocks are fixedly connected to a mounting plate.

[0015] By adopting the above technical solution, during the sliding process of the transmission block, the limiting block is driven to slide inside the limiting groove, thereby driving the mounting plate to slide back and forth.

[0020] By adopting the above technical solution, during the downward movement of the mounting plate, the guide cylinder and guide rod are driven to move downward until the pressure plate contacts the surface of the concrete block. At this time, the guide rod slides inside the guide groove, and the positioning block slides inside the positioning groove to position the guide rod.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 3 The illustrated aerated concrete block grooving device includes a working platform 1, with support rods 11 fixedly connected to each of the four corners of the working platform 1. Support plates 12 are fixedly connected to the upper ends of the four sets of support rods 11. A hydraulic cylinder 13 is fixedly installed at the center of the upper surface of the support plate 12. An equipment housing 2 is fixedly connected to the output end of the hydraulic cylinder 13. Two sets of limiting rods 21 are fixedly connected to the front and rear surfaces of the equipment housing 2. The end of the limiting rod 21 facing away from the equipment housing 2 is slidably connected to the support rod 11. An adjustment assembly is provided inside the equipment housing 2. The adjustment assembly includes a first motor 23, a precision screw 24, a linear guide rail 25, a transmission block 26, a linear bearing 27, a limiting block 28, a mounting plate 3, a second motor 32, and a cutting blade 34.

[0034] The hydraulic cylinder 13 is used to adjust the height of the cutting blade 34. During use, the concrete block is placed on the surface of the work platform 1, and then the hydraulic cylinder 13 and the second motor 32 are started. The output end of the second motor 32 drives the cutting blade 34 to rotate. At the same time, the telescopic rod in the hydraulic cylinder 13 pushes the equipment shell 2 downward. At this time, the limit rod 21 slides downward on the surface of the support rod 11 to limit the equipment shell 2. During the downward movement of the equipment shell 2, the mounting plate 3 and the cutting blade 34 are pushed downward to groove the surface of the concrete block. When grooving is required at different positions, the first motor 23 drives the precision screw 24 to rotate, which, together with the transmission block 26, drives the mounting plate 3 to slide back and forth, thereby adjusting the position of the cutting blade 34 and improving the convenience of adjusting the cutting blade 34.

[0035] See Figure 2 and Figure 3 The precision screw 24 is rotatably connected to the inner walls of the front and rear sides of the equipment housing 2. Linear guide rails 25 are fixedly connected to the inner walls of the front and rear sides of the equipment housing 2 at the positions on the left and right sides of the precision screw 24. The first motor 23 is fixedly installed at the rear end of the equipment housing 2. The output end of the first motor 23 is fixedly connected to the rear end of the precision screw 24 through a coupling. The transmission block 26 is threadedly connected to the precision screw 24. The linear bearing 27 is slidably connected to the linear guide rail 25. The two sets of linear bearings 27 are fixedly connected to the left and right sides of the transmission block 26 respectively. Two sets of limiting grooves 22 are opened on the lower surface of the equipment housing 2. Limiting blocks 28 are slidably connected inside the two sets of limiting grooves 22. The upper ends of the two sets of limiting blocks 28 are fixedly connected to the two sets of linear bearings 27 respectively. The lower ends of the two sets of limiting blocks 28 are fixedly connected to the mounting plate 3.

[0036] Specifically, the output end of the first motor 23 rotates clockwise, driving the precision screw 24 to rotate clockwise. During the rotation of the precision screw 24, with the cooperation of the linear bearing 27 and the linear guide rail 25, the transmission block 26 is driven to slide backward on the surface of the precision screw 24. The transmission block 26 drives the limiting block 28 to slide backward inside the limiting groove 22. The limiting block 28 drives the mounting plate 3 to slide backward. The mounting plate 3 drives the second motor 32 and the cutting blade 34 to move backward, adjusting the position of the cutting blade 34.

[0037] See Figures 4 to 6A fixing plate 31 is fixedly connected to the lower surface of the mounting plate 3. A second motor 32 is fixedly installed on the rear surface of the fixing plate 31. A mounting shaft 33 is fixedly connected to the output end of the second motor 32. A cutting blade 34 is sleeved on the surface of the mounting shaft 33. A locking nut 35 is threadedly connected to the front end of the mounting shaft 33. Two sets of guide cylinders 36 are fixedly connected to the lower surface of the mounting plate 3. A guide rod 38 is slidably connected inside the guide cylinder 36. Two sets of positioning grooves 37 are opened on the surface of the guide cylinder 36. Two sets of positioning blocks 39 are fixedly connected to the upper end of the guide rod 38. The positioning blocks 39 are slidably connected to the positioning grooves 37. A pressure plate 311 is fixedly connected to the lower end of the two sets of guide rods 38. A support spring 310 is sleeved on the surface of the guide cylinder 36 and the guide rod 38. The upper and lower ends of the support spring 310 abut against the lower surface of the mounting plate 3 and the upper surface of the pressure plate 311, respectively.

[0038] In addition, during the grooving process of the concrete block, as the mounting plate 3 moves downward, it drives the guide cylinder 36, guide rod 38 and pressure plate 311 to move downward until the pressure plate 311 contacts the surface of the concrete block. As the mounting plate 3 continues to move downward, the guide rod 38 slides upward inside the guide cylinder 36 and squeezes the support spring 310. At this time, the support spring 310 and the pressure plate 311 cooperate to press the concrete block tightly, improving the stability of the concrete block during the grooving process.

[0039] As should be added, during the replacement of the cutting blade 34, the locking nut 35 can be unscrewed to remove the cutting blade 34. During the installation process, the cutting blade 34 is directly placed on the surface of the mounting shaft 33. At this time, the locking nut 35 is fixed to the front end of the mounting shaft 33 to fix the cutting blade 34, which makes it easy to replace the cutting blade 34.

[0040] The working principle of this utility model is as follows: The position of the mounting plate 3 is adjusted back and forth by the cooperation of the first motor 23, precision screw 24, linear guide rail 25, transmission block 26 and linear bearing 27, thereby adjusting the position of the cutting blade 34, improving the convenience of adjusting the cutting blade 34 and improving the efficiency of grooving concrete blocks; At the same time, the concrete block is pressed by the cooperation of the guide cylinder 36, guide rod 38, support spring 310 and pressure plate 311, improving the stability of the concrete block in the grooving process, thereby effectively improving the accuracy of grooving concrete blocks.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
