Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerated concrete block cutting technology, specifically to a dust prevention device for cutting aerated concrete blocks at construction sites. Background Technology
[0002] Autoclaved aerated concrete (AAC) blocks are a lightweight, porous, and environmentally friendly building material. They are made from raw materials such as cement, lime, sand, fly ash, and foaming agents through mixing, foaming, cutting, and autoclaving. They are characterized by their light weight, good thermal insulation, strong fire resistance, and good workability. They are widely used in non-load-bearing walls, roof insulation layers, and firewalls. Although they have relatively low strength and are prone to water absorption, their excellent energy-saving and economical properties make them one of the important green building materials in modern architecture. They are especially suitable for partition walls and energy-saving renovation projects in residential and office buildings.
[0003] Because aerated concrete blocks contain a large number of tiny pores, these pore structures are destroyed during the cutting process, releasing a large amount of fine dust. At the same time, construction sites are usually open and well-ventilated environments with low air humidity, making the dust more likely to remain suspended in the air. In addition, when the wind speed is high, the dust will be blown to a more distant area, further expanding its diffusion range. This not only exacerbates environmental pollution at the construction site, but also poses a serious threat to the health of workers. Utility Model Content
[0004] The purpose of this utility model is to provide a dust prevention device for cutting aerated concrete blocks at construction sites, so as to overcome the shortcomings of the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A dust-proof device for cutting aerated concrete blocks at a construction site includes a base plate. Four rectangularly arranged brake casters are fixedly installed on the bottom of the base plate. A cutting groove is formed on the top of the base plate. Two symmetrically arranged support plates are fixedly installed on the top of the base plate. Two guide rods, arranged front-to-back, are fixedly installed between the two support plates. The outer sides of both guide rods are slidably connected to the bottom of the mounting plate.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0023] Example 1, as Figures 1-6As shown, a dustproof device for cutting aerated concrete blocks at a construction site includes a base plate 1. Four rectangular brake casters 2 are fixedly installed on the bottom of the base plate 1. A cutting groove 3 is formed on the top of the base plate 1. Two symmetrically distributed support plates 4 are fixedly installed on the top of the base plate 1. Two guide rods 5, arranged front-to-back, are fixedly installed between the two support plates 4. The outer sides of both guide rods 5 are slidably connected to the bottom of a mounting plate 6. A cutting machine 7 is fixedly installed on the top of the mounting plate 6. The cutting blade of the cutting machine 7 extends into the cutting groove 3. A fan 8 is fixedly installed on the top of the base plate 1. A duct 9 is installed on the top of the base plate 1. A dust collection box 10 is fixedly installed on the top of the base plate 1. A connecting frame 11 is fixedly installed on the bottom of the mounting plate 6. A guide plate 12 is fixedly installed on the bottom of the connecting frame 11. Guide grooves 13 are opened on both the left and right sides of the guide plate 12. A suction pipe 14 is fixedly installed inside the two guide grooves 13. The rear side of the two suction pipes 14 is connected to the interior of the duct 9 through a pipe. The front side of the fan 8 is connected to the interior of the duct 9 through a pipe. The rear side of the fan 8 is connected to the interior of the dust collection box 10 through a pipe.
[0024] Under the action of the brake caster 2, the base plate 1 can be moved to a designated position. When cutting the aerated concrete block, the cutting machine 7 is started, and the operator moves the cutting machine 7 to cut the aerated concrete block (this cutting step is a conventional technical means in this field, so it will not be described in detail). The exhaust fan 8 is started, and the dust generated during the cutting process is drawn into the air duct 9 through the dust suction pipe 14. Then, under the action of the exhaust fan 8, it is transported to the dust collection box 10 to complete the collection of dust and further reduce the impact of the dust generated during cutting on the surrounding environment.
[0025] Example 2 is a further improvement based on Example 1, and it is as follows: A support platform 15 is fixedly installed on the top of the base plate 1, and the support surface of the support platform 15 is in contact with the outer side of the air duct 9.
[0026] The support platform 15 further supports the air duct 9 to ensure stability during the dust extraction process.
[0027] Example 3 is a further improvement based on Example 1, and it is as follows: both suction pipes 14 are fitted with suction nozzles 16 on their outer sides.
[0028] When further vacuuming is performed through the suction nozzle 16, the suction power is more concentrated, which can effectively reduce the flying and spreading of dust during the vacuuming process. This helps to reduce the risk of secondary pollution and maintain the cleanliness of the environment.
[0029] Example 4 is a further improvement based on Example 1, and it is as follows: The top of the dust collection box 10 is provided with a sliding groove 17, and a baffle 18 is slidably installed inside the sliding groove 17.
[0030] When cleaning the inside of the dust collection box 10, simply move the baffle 18 upwards to remove the baffle 18 and clean the inside of the dust collection box 10.
[0031] Example 5 is a further improvement based on Example 1. Specifically, a guide block 19 is fixedly installed on the bottom of the base plate 1, and a dust collection box 20 is slidably installed inside the guide block 19. The dust collection box 20 is located directly below the cutting groove 3.
[0032] During the cutting process of aerated concrete blocks, the dust generated at the bottom will enter the dust collection box 20 through the cutting groove 3, further reducing dust pollution and facilitating subsequent cleaning.
[0033] Example 6 is a further improvement on Example 5, and is as follows: The bottom of the guide block 19 is provided with a limiting hole 21 extending into the dust collection box 20. A limiting rod 22 is slidably installed inside each of the two limiting holes 21. A pull rod 23 is fixedly installed at the bottom of each of the two limiting rods 22. Two springs 24 are fixedly installed at the top of each of the two pull rods 23 and are symmetrically distributed on the left and right. The top of all the springs 24 is fixedly connected to the bottom of the guide block 19.
[0034] When installing the dust collection box 20, pull the limiting rod 22 downward to slide the dust collection box 20 into the guide block 19, thereby releasing the pull rod 23. Under the action of the spring 24, the limiting rod 22 re-enters the limiting hole 21, completing the restriction of the dust collection box 20, which can better collect the dust generated during the cutting process.
[0035] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
