Description

A construction material cutting device for civil engineering

Technical Field

The utility model relates to the technical field of civil engineering, in particular to a building material cutting device for civil engineering.

Background Art

Various building materials are needed in civil engineering construction, and when these building materials are used, they need to be cut into the required size by corresponding cutting equipment.

However, the existing civil engineering building material cutting device will generate a large amount of dust or fragments when cutting building materials. Too much dust accumulation will easily affect the vision, and the workers will inhale a large amount of dust, which will also affect their health. Therefore, it is necessary to vacuum the building materials when cutting them. The existing building material cutting device has dust collection measures, which are mostly carried out by installing fans. However, the fans and the dust collection pipes of the fans are mostly fixed in a certain place and do not move. Therefore, the dust collection effect will be poor at a long distance from the dust collection pipe.

Utility Model Content

In view of the deficiencies in the prior art, the utility model provides a construction material cutting device for civil engineering, which solves the technical problem that the dust suction mechanism in the prior art construction material cutting device has poor dust suction effect when it is far away from the dust suction pipe when suctioning dust, and achieves the purpose that the dust suction hood always moves with the circular saw during cutting and always suctions dust under the circular saw.

In order to solve the above technical problems, the utility model provides the following technical solutions: a construction material cutting device for civil engineering, comprising a workbench, on which is installed a cutting mechanism for cutting construction materials, on which is installed a dust collection mechanism for dust collection, and at both ends of the workbench are installed an unfolding mechanism for increasing the usable area.

The cutting mechanism includes two support plates fixed on the lower end surface of the workbench, a screw rod is rotatably connected between the support plates, a nut seat is mounted on the screw rod, a cutting machine is installed on the nut seat, a rotating shaft is fixed on the output shaft of the cutting machine, a circular saw is fixed on the rotating shaft, and a motor for driving the screw rod to rotate is installed on the support plates.

The dust suction mechanism includes two wind wheels fixed on a rotating shaft, the two wind wheels are installed on both sides of the circular saw, a trumpet-shaped dust suction hood is provided under the circular saw, the dust suction hood is fixedly connected to the nut seat, and a dust suction pipe is connected and installed at the lower end of the dust suction hood, and a dust collection box is connected and installed at the other end of the dust suction pipe, and the rotating shaft is movably connected to the dust suction hood.

Furthermore, a cutting groove is provided in the middle of the workbench at a position corresponding to the circular saw.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Fig. 1-Fig. 5 are an embodiment of the utility model: a construction material cutting device for civil engineering, comprising a workbench 1, on which is mounted a cutting mechanism 2 for cutting construction materials, on which is mounted a dust collecting mechanism 3 for dust collection, and at both ends of the workbench 1 are mounted an unfolding mechanism 4 for increasing the usable area.

As shown in Figures 1-2, the cutting mechanism 2 includes two support plates 201 fixed on the lower end surface of the workbench 1, a screw rod 202 is rotatably connected between the support plates 201, a nut seat 203 is mounted on the screw rod 202, a cutting machine 204 is installed on the nut seat 203, a rotating shaft is fixed on the output shaft of the cutting machine 204, a circular saw 205 is fixed on the rotating shaft, a motor 206 for driving the screw rod 202 to rotate is installed on the support plate 201, a cutting groove is opened in the middle of the workbench 1 at a position corresponding to the circular saw 205, a limiting rod 207 is fixed on the support plate 201, and the nut seat 203 is slidably connected to the limiting rod 207. Put the building materials on the workbench 1, fix them, start the motor 206 and the cutting machine 204, the cutting machine 204 drives the circular saw 205 to rotate and cut the building materials, the motor 206 drives the screw rod 202 to rotate, and at the same time drives the nut seat 203 to rotate, and the nut seat 203 is limited by the limiting rod 207, so that the nut seat 203 can be driven to move. When cutting the building materials, the building materials are not moved manually, but the cutting machine 204 and the circular saw 205 are driven by the nut seat 203 to move and cut the building materials.

2-3, the dust suction mechanism 3 includes two wind wheels 301 fixed on a rotating shaft, the two wind wheels 301 are installed on both sides of the circular saw 205, a trumpet-shaped dust suction hood 302 is provided under the circular saw 205, the dust suction hood 302 is fixedly connected to the nut seat 203, and the lower end of the dust suction hood 302 is connected and installed with a dust suction pipe 303, the dust suction pipe 303 is long enough and is designed with a threaded hose material, the other end of the dust suction pipe 303 is connected and installed with a dust collecting box 304, and the rotating shaft and the dust suction hood 302 are movably connected. When the circular saw 205 rotates to cut the building materials, it also drives the wind wheels 301 on both sides to rotate. The rotation of the wind wheels 301 will generate negative pressure, so dust is generated during cutting. The dust can be sucked through the rotation of the wind wheels 301, and enters the dust pipe 303 through the dust hood 302, and finally reaches the dust box 304. During the dust suction process, the dust hood 302 is fixedly connected to the nut seat 203. Therefore, during the cutting process, the dust hood 302 moves with the circular saw 205, so that dust is always sucked directly at the cutting position, thereby improving the dust suction effect, and no vacuum cleaner is installed, thereby reducing manufacturing costs and electricity usage expenses.

4 and 5 , in this embodiment, the unfolding mechanism 4 includes an extension plate 401 rotatably connected to both sides of the workbench 1, a rotating rod is fixed on the extension plate 401, a gear 402 is mounted on the rotating rod, a serrated block 403 for limiting is provided on the outer side of the gear 402, a pull rod 404 is fixed on the serrated block 403, a baffle is fixed on the workbench 1, the pull rod 404 is slidably connected to the baffle, and a spring 405 is mounted on the pull rod 404, and the spring 405 is installed between the serrated block 403 and the baffle. When the length of the raw material is long and the length of the workbench 1 is not enough, pull the pull rod 404 to rotate the extension plate 401 upward until it is flush with the height of the workbench 1, and then release the pull rod 404. Under the action of the spring 405, the pull rod 404 and the sawtooth block 403 are driven to reset, so that the sawtooth block 403 limits the gear 402. The use of the extension plate 401 can increase the use area of the workbench 1, prevent the construction materials from being too long, and prevent the possibility of warping and falling off after cutting, thereby improving the safety of processing.

As shown in FIG4 , in this embodiment, the lower end of the extension plate 401 is rotatably connected to a U-shaped bracket 4011, and a hook 4012 used in conjunction with the bracket 4011 is fixed to the side of the workbench 1. After the extension plate is rotated to a position flush with the height of the workbench 1, the bracket 4011 is rotated and placed into the hook 4012 on the workbench 1, thereby increasing the support for the extension plate 401 and strengthening the load-bearing capacity of the extension.
