Description

Technical Field

[0001] This utility model relates to the technical field of block cutting equipment, specifically a small aerated concrete block cutter. Background Technology

[0002] Aerated concrete blocks are lightweight porous silicate products made from siliceous materials (sand, fly ash, and silica-containing tailings, etc.) and calcareous materials (lime, cement) as the main raw materials, with the addition of a foaming agent (aluminum powder). They are produced through processes such as batching, mixing, pouring, pre-curing, cutting, autoclaving, and curing. Because they contain a large number of uniform and fine pores after aeration, they are called aerated concrete blocks. They often need to be cut during wall construction, so a cutter is required.

[0003] A search revealed a patent, CN208052302U, which discloses a small aerated concrete block cutter. This cutter includes a frame, a conveyor roller, a hydraulic jack, a movable cutting blade, a fixed cutting blade, and a guide groove. The conveyor roller consists of a connecting shaft and rolling wheels, with the rolling wheels connected to the rotating shaft. At least two connecting shafts are fixed to the top of the frame. A guide groove is fixed to one side of the frame, and a fixed cutting blade is positioned at the upper end of the guide groove. A hydraulic jack is fixed to the frame directly below the fixed cutting blade. A movable cutting blade slides within the guide groove and is connected to the telescopic end of the hydraulic jack, which pushes the movable cutting blade up and down. This invention has a simple structure, is easy to operate, and can cut concrete blocks into small pieces of any size as needed. The cut concrete blocks are neat and tidy, saving labor intensity.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes cutting concrete blocks by placing them on a frame and using a jack to drive a cutting blade. However, in reality, when cutting concrete blocks, it is necessary to ensure that the cut is not tilted and to guarantee the dimensions of the cut blocks. The aforementioned comparative document requires manually aligning the concrete blocks on the frame, which reduces the efficiency of cutting the concrete blocks. Therefore, there is an urgent need in the art to improve the block cutter to overcome the shortcomings of the prior art. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 A small aerated concrete block cutter includes a support plate 1, a support platform 2 on the upper part of the support plate 1, a placement frame 3 on the upper part of the support platform 2, a plurality of sliding rack plates 4 equidistantly distributed in four directions slidably connected inside the support platform 2, a drive unit 5 at the lower part of the support platform 2 for driving the plurality of sliding rack plates 4 to move synchronously in opposite directions, a clamping frame 6 on the upper part of the sliding rack plates 4, a top plate 7 above the placement frame 3, a sliding seat 8 on the top plate 7, a telescopic device 9 with a telescopic effect on the upper part of the sliding seat 8, the telescopic end of the telescopic device 9 passing through the sliding seat 8 and the end of its end having a cutter 10 for cutting, the drive unit 5 including a drive motor 11 fixedly installed at the lower part of the support platform 2, a rotating gear ring 12 rotatably connected inside the support platform 2 and in close contact with the sides of the plurality of sliding rack plates 4, and a plurality of gears 13 rotatably connected inside the support platform 2, the gears 13 meshing with the rotating gear ring 12 and the sliding rack plates 4.

[0030] Specifically, when it is necessary to cut concrete blocks, the concrete blocks to be cut are placed in the placement frame 3, roughly positioned according to the desired cutting location. The drive motor 11 is started, and the output end of the drive motor 11 drives one of the gears 13 to rotate. When the gear 13 rotates, it drives the rotating gear ring 12 to rotate. When the rotating gear ring 12 rotates, it drives the other gears 13 to rotate. Several gears 13 drive several corresponding sliding rack plates 4 to move towards each other. The sliding rack plates 4 drive the clamping frame 6 to move. Several clamping frames 6 center and clamp the concrete block, and displace the position of the sliding seat 8 on the top plate 7, moving the position of the cutter 10 to the concrete block to be cut. When the position is reached, the telescopic device 9 is activated. The telescopic end of the telescopic device 9 drives the cutter 10 to move downward. The cutter 10 moves downward to cut the concrete block. Due to its own structure, the aerated concrete block can be cut by the pressure applied by the cutter 10 when it moves downward. If it is clamped, it is difficult to cut the concrete block. When the cutter 10 contacts and presses the upper part of the concrete block, the drive motor 11 is started in reverse to drive several clamping frames 6 away from the concrete block. The position of the clamping frames 6 can be adjusted according to the actual situation. The clamping frames 6 can center and clamp the concrete block to be cut, improving the accuracy and efficiency of cutting the concrete block.

[0031] As a technical optimization of this utility model, a movable groove 14 adapted to the sliding seat 8 is provided through the upper part of the top plate 7. Two movable threaded rods 15 with one end fixedly installed on one side of the sliding seat 8 are provided through one end of the top plate 7. A first connecting rod 16 is fixedly installed between the ends of the two movable threaded rods 15 away from the sliding seat 8. A scale plate 30 with graduations is provided on the upper part of the top plate 7. A limiting unit for limiting the movable threaded rods 15 is provided at one end of the top plate 7. The limiting unit includes a fixed frame 17 fixedly installed on the upper part of one end of the top plate 7. Two movable columns 18 are provided through the fixed frame 17. A limiting threaded plate 19 adapted to the movable threaded rod 15 is fixedly installed at the lower end of the movable column 18. A spring 20 sleeved on the side of the movable column 18 is provided between the upper part of the limiting threaded plate 19 and the fixed frame 17. A second connecting rod 21 is fixedly installed between the upper ends of the two movable columns 18.

[0032] Specifically, when the position of the cutter 10 needs to be adjusted, pull the second connecting rod 21 upward. The second connecting rod 21 drives the two moving columns 18 to move upward, and the moving columns 18 drive the limiting threaded plate 19 to move upward. At this time, the spring 20 is compressed, and the side of the limiting threaded plate 19 disengages from the moving threaded rod 15. Pull the first connecting rod 16 to adjust the position of the sliding seat 8 in the moving groove 14. Adjust the position of the sliding seat 8 according to the scale on the scale plate 30. After the position of the cutter 10 is adjusted, release the second connecting rod 21. After the second connecting rod 21 is released, the tension of the spring 20 pushes the limiting threaded plate 19 downward. The threads on the side of the limiting threaded plate 19 engage with the threads on the side of the moving threaded rod 15, limiting and fixing the position of the moving threaded rod 15, which facilitates the quick adjustment and fixing of the position of the cutter 10.

[0033] As a technical optimization of this utility model, a sliding plate 22 is fixedly installed on the lower part of the clamping frame 6, and a sliding groove 23 adapted to the sliding plate 22 is opened on the upper part of the sliding rack plate 4. One end of the sliding rack plate 4 passes through and is threadedly connected to an adjusting threaded rod 24 that extends into the sliding groove 23. The adjusting threaded rod 24 passes through the sliding plate 22 and is threadedly connected to it. A limit nut 25 is threadedly connected to the side of the adjusting threaded rod 24.

[0034] Specifically, by rotating the adjusting threaded rod 24, the sliding plate 22 is driven to move within the sliding groove 23. The sliding plate 22 drives the clamping frame 6 to move, adjusting the position of the clamping frame 6 on several sliding rack plates 4. Then, the locking limit nut 25 is tightened to limit and fix the position of the sliding plate 22. This is suitable for positioning and clamping concrete blocks of different rectangular shapes, improving the applicability of the overall device.

[0035] As a technical optimization of this utility model, a plug-in block 26 is fixedly installed on the upper part of the cutter 10, and a plug-in groove 27 adapted to the plug-in block 26 is opened at the lower end of the telescopic device 9. A positioning bolt 28 with one end threadedly connected to the side of the plug-in block 26 passes through the lower side of the telescopic device 9.

[0036] Specifically, the upper part of the cutter 10 inserts the plug 26 into the plug groove 27, and one end of the positioning bolt 28 passes through the plug 26. One end of the positioning bolt 28 is threaded to the side of the plug groove 27, which facilitates the installation or replacement of the cutter 10.

[0037] As a technical optimization of this utility model, a positioning block 29 is fixedly installed at the lower part of the placement frame 3 and inserted into the upper part of the support platform 2. A limiting post 31 that passes through the sliding seat 8 is threadedly connected to the upper part of the cutter 10. The placement frame 3 is inserted into the upper part of the support platform 2 through the positioning block 29. When the debris after cutting the concrete block needs to be cleaned, the placement frame 3 can be removed directly. At the same time, different sizes of placement frames 3 can be replaced to improve the practicality and applicability of the overall device. The limiting post 31 is mainly used to limit the up and down movement of the cutter 10.
