Description

Technical Field

[0001] The utility model relates to the field of brick and stone cutting technology, specifically to a portable dust-free brick and stone cutting device. Background Technology

[0002] Masonry is one of the commonly used construction materials in building construction. When using it, it is generally used directly or needs to be cut into the required shape before it is put into use. In the current technology, when cutting masonry, special stone cutting machines are generally used.

[0003] During the cutting process, workers place the brick and stone material in the cutting position of the cutting machine, then start the cutting machine and manually control the movement of the brick and stone material or the cutting structure to complete the cutting of the brick and stone material. After the cutting is completed, the cut brick and stone material is removed, and then the next piece is cut.

[0004] However, the current cutting machine is limited to a fixed position and cannot move freely. Especially in the construction environment, the roadside is not flat, which brings great inconvenience to the movement of the cutting machine. It forces the construction workers to transport the bricks and stones to the location of the cutting machine for cutting, and then transport the cut bricks and stones to the construction site. The operation is inconvenient and the efficiency is low, which urgently needs to be improved.

[0005] Furthermore, the cutting process generates a significant amount of dust particles. The dust particles released by the cutting machine when cutting brick and stone materials pose a significant potential threat to human health and affect the health of the workers.

[0006] Furthermore, currently, brick and stone materials are cut manually piece by piece during the cutting process, which is inefficient. Utility Model Content

Detailed Implementation

[0044] Example 1:

[0045] like Figure 1 , 2 As shown in Figures 3 and 5, a portable dust-free brick and stone cutting device includes a base plate 1, on which a cutting machine 3 and a dust removal mechanism are provided. A support leg 2 is provided at the bottom of the base plate 1, and a walking mechanism is provided at the bottom end of the support leg 2. The cutting machine 3 refers to the cutting structure used in existing brick and stone cutting machines. The cutting disc 302 is controlled to rotate using existing technology to complete the cutting of bricks and stones.

[0046] The dust removal system is used to handle the dust generated by the cutting machine 3 when cutting bricks and stones;

[0047] The walking mechanism is used for movement.

[0048] When in use, the walking mechanism assists in movement, which can effectively increase the convenience of moving the cutting device. During cutting, the dust removal mechanism directly treats the dust generated during the cutting of bricks and stones, avoiding the dust from affecting the surrounding environment and the health of the workers.

[0049] In the preferred embodiment, the top of the base plate 1 is provided with a dust cover 101, and the side of the dust cover 101 is provided with a feed hole 102; the cutting machine 3 is connected to the dust cover 101 by screws 301, and the cutting disc 302 of the cutting machine 3 extends into the interior of the dust cover 101; when needed, the cutting machine 3 can be removed by unscrewing the screws 301, and vice versa, making it easy to operate, easy to replace, and easy to use independently; after disassembly, transportation is easier and it is easier to handle.

[0050] Dust cover 101 is used to prevent dust generated by the cutting machine 3 from being emitted outwards when cutting bricks and stones;

[0051] By setting up the dustproof shell 101, the brick cutting process is carried out inside the dustproof shell 101, which can prevent dust from spreading and thus avoid affecting the on-site staff.

[0052] The dust removal mechanism includes: a dust cover 101 with a mounting sleeve 403, the mounting sleeve 403 being connected to a vacuum cleaner 4, the vacuum cleaner 4 having a suction pipe 401 at its suction end, the suction pipe 401 having a suction head 402, the suction head 402 being located on the side of the dust cover 101 for sucking up dust inside the dust cover 101; the vacuum cleaner 4 is an existing industrial vacuum cleaner; the suction head 402 has multiple suction holes communicating with the suction pipe 401, ensuring that dust can be sucked in through the suction holes and then enter the suction pipe 401 through the suction holes;

[0053] The dust cover 101 has two guide plates 404 inside; the ends of the two guide plates 404 near the air intake 402 are close to each other to guide dust into the air intake 402.

[0054] When cutting, the vacuum cleaner 4 is turned on to generate suction. This suction acts on the position of the suction head 402, and the dust generated during cutting will enter the vacuum cleaner 4 after passing through the suction head 402 and the suction pipe 401. It is simple to operate and easy to deal with the dust generated during cutting bricks and stones.

[0055] Example 2:

[0056] like Figure 1 , 2 As shown in Figures 3 and 4, a placement plate 5 is provided on the top of the base plate 1. The placement plate 5 is located between two guide plates 404. A second handrail 501 is provided on the side of the placement plate 5 closest to the feed hole 102. A cutting groove 502 is provided on the side of the placement plate 5 away from the second handrail 501. The cutting groove 502 is on the same plane as the cutting disc 302.

[0057] The top of the placement plate 5 is provided with a dustproof plate 503, and the dustproof shell 101 is provided with a positioning block 504. The dustproof plate 503 can prevent dust from being scattered through the feed hole 102, and the positioning block 504 can control the sliding distance of the placement plate 5 by limiting the distance of the dustproof plate 503.

[0058] The top of the base plate 1 is provided with a guide roller 505. The guide roller 505 is close to the feed hole 102 and located at the bottom of the placement plate 5. The placement plate 5 can be supported by the guide roller 505 so as to facilitate the relative sliding between the placement plate 5 and the base plate 1.

[0059] The top of the base plate 1 is provided with a guide groove 506, and the side of the placement plate 5 away from the second handrail 501 is provided with a guide wheel 507. The guide wheel 507 rolls along the guide groove 506. When the base plate 1 slides, the guide wheel 507 rolls along the guide groove 506, which plays a role in guiding and increasing the smoothness of the sliding of the placement plate 5.

[0060] When using the device, place the brick to be cut on the placement plate 5 and align the area to be cut with the cutting groove 502. Then, hold the second handle 501 and push the placement plate 5 into the dust cover 101. This will bring the brick closer to the cutting disc 302, thus completing the cutting. After cutting, pull out the placement plate 5, remove the cut brick, and place a new brick. The operation is simple and convenient for cutting.

[0061] Example 3:

[0062] like Figure 7 As shown, the dustproof plate 503 is threadedly connected to two threaded rods 508, which pass through the dustproof plate 503 and are not connected to the two sides of the cutting groove 502; the end of the threaded rod 508 near the second handrail 501 is provided with a handle 510, and the end of the threaded rod 508 away from the second handrail 501 is provided with a push plate 509.

[0063] After the bricks and stones are placed, the threaded rod 508 is rotated by rotating the handle 510, which causes the threaded rod 508 to move relative to the dustproof plate 503, thereby driving the push plate 509 to move. The push plate 509 then presses against the bricks and stones to be cut, thus positioning the bricks and stones and preventing displacement during cutting.

[0064] Example 4:

[0065] like Figure 3 , 4 As shown in 5, 6 and 7, when the shape of the bricks and stones is uneven or needs to be fixed, the top of the placement plate 5 is provided with a fixing mechanism 6, which is used to position the bricks and stones.

[0066] The fixing mechanism 6 includes: a plurality of sliding grooves 601 on the top of the placement plate 5, and a slider 602 in the sliding grooves 601; a plurality of positioning plates 604 on the top of the placement plate 5, and a pad 605 on the top of the positioning plate 604; a threaded post 603 is screwed to the top of the slider 602, the threaded post 603 passes through the positioning plate 604 and the pad 605, and a knob 606 is provided on the top of the threaded post 603;

[0067] The cross-section of the slide groove 601 is T-shaped, and the slider 602 is adapted to the slide groove 601, with a gap between the slider 602 and the slide groove 601.

[0068] After placing the bricks and stones, slide the positioning plate 604. At this time, the slider 602 slides in the groove 601. When the positioning plate 604 slides to the desired position, the bricks and stones to be cut are clamped. Then, turn the knob 606 to drive the threaded post 603 to rotate. This will cause the threaded post 603 to rotate into the slider 602, thus clamping the positioning plate 604, the pad 605, and the part of the placement plate 5 above the groove 601 between the knob 606 and the slider 602, completing the fixation. The operation is simple and it is effective in positioning and fixing the cut bricks and stones.

[0069] Example 5:

[0070] like Figure 1 and 2 As shown, a first handrail 103 is provided on the side of the base plate 1 near the feed hole 102; the walking mechanism includes: a fixed shaft 201 is provided on the support leg 2 away from the first handrail 103, and a rotating frame 202 is provided at both ends of the fixed shaft 201, and a roller 203 is rotatably connected to the rotating frame 202.

[0071] The rotating frame 202 can rotate relative to the supporting leg 2;

[0072] The rotating frame 202 includes three support rods, and the ends of the support rods are rotatably connected to rollers 203.

[0073] When moving, grasp the first handrail 103 and lift it upwards to raise the support leg 2 near the first handrail 103, and then pull to move the cutting device. During the movement, the rollers 203 roll on the ground. When encountering small potholes, two rollers 203 on the same rotating frame 202 will contact the ground simultaneously, and the entire walking mechanism will have at least four rollers 203 in contact with the ground, which can ensure the stability during movement. When encountering larger potholes, it is not just the rollers 203 that rotate, but the entire rotating frame 202 rotates to cross the potholes, thus facilitating movement in complex environments such as construction sites and increasing the convenience of movement.

[0074] The method of using the portable dust-free brick and stone cutting device provided in this application includes the following steps:

[0075] S1. Lift one end of the base plate 1 and move the cutting device to the working position with the assistance of the traveling mechanism;

[0076] S2. Place the bricks to be cut onto the moving mechanism;

[0077] S3. Start the cutting machine 3 and the dust removal mechanism, and move the bricks to be cut into the dustproof shell 101 through the moving mechanism;

[0078] S4, Cutting machine 3 completes the cutting of the bricks and stones;

[0079] The dust generated during cutting accumulates inside the dustproof housing 101 and is treated by the dust removal mechanism;

[0080] S5. Remove the cut bricks and stones.

[0081] In S2 and S3, the moving mechanism includes the placement plate 5.

[0082] The above method not only facilitates the movement of the cutting device in complex environments such as construction sites, increasing its mobility, but also eliminates the need to transport large quantities of bricks and stones for cutting, resulting in higher efficiency. Furthermore, it avoids the spread of dust generated during cutting, thus preventing dust from adversely affecting the health of on-site personnel.

[0083] The above embodiments are merely preferred technical solutions of the utility model and should not be considered as limitations on the utility model. The protection scope of the utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of the utility model.
