Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a cutting device for permeable concrete. Background Technology

[0002] To prevent structural cracks or damage caused by changes in climate and temperature (thermal expansion and contraction), a structural joint (i.e., an expansion joint) is set at an appropriate location along the construction joint direction of a building or structure. Traditional joint cutters are simply single-blade cutters that cut at predetermined locations before the concrete has hardened.

[0003] In response, Chinese patent application number CN202222389654.0 discloses a recycled concrete joint cutter, relating to the technical field of joint cutters. The cutter includes a cutter blade with symmetrically arranged connecting parts and a bucket on its left and right sides, the connecting parts and the bucket being interconnected. Two sets of connecting parts are connected to the cutter blade via a fixing part and a collar. A sliding track is provided inside the cutter blade. A through hole is provided inside the connecting part. The bucket consists of a shovel head, a receiving part, and a mudguard. The shovel head is designed with an increasing inclination from left to right, and the mudguard has an arc-shaped folded edge. The fixing part passes through the sliding track and the through hole, and a collar is connected to the outer wall of the fixing part. This utility model, by providing a bucket, allows the shovel head to scoop up overflowing concrete, and the mudguard prevents it from falling back onto the concrete surface, thus preventing the concrete plane on both sides of the expansion joint from rising and ensuring the flatness of the concrete plane.

[0004] This slit cutter allows for adjustment of the position between the bucket and the cutter by setting a fixing component, making it easy to cut expansion joints of different depths. However, in actual use, since the connecting component is installed in the slide on the cutter through the fixing component, the bucket is prone to displacement in the slide when the fixing component becomes loose, resulting in inconsistent cutting depths and affecting the user experience.

[0005] Therefore, in order to solve the above problems, a permeable concrete cutting device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a permeable concrete cutting device to solve the problem mentioned in the background art that the existing cutting device can adjust the position between the bucket and the cutter by setting a fixing member to facilitate cutting expansion joints of different depths. However, in actual use, since the connecting member is installed in the slide on the cutter through the fixing member, the bucket is prone to displacement in the slide when the fixing member is loose, which leads to inconsistent cutting depth and affects the user experience.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a permeable concrete cutting device, comprising: a bucket;

[0008] The bucket is equipped with an adjustment structure, which includes a cover plate. The cover plate is fixedly installed at the top edge of the bucket. A bracket is fixedly connected to the top surface of the cover plate. A hand-threaded rod is threadedly connected to the surface of the bracket. A cutter is rotatably connected to the bottom end of the hand-threaded rod. A scale rod is fixedly connected to the top surface of the cutter. A limit block is fixedly connected to the upper end of the scale rod.

[0009] Preferably, the bucket and the cover plate are provided in two sets, and the bucket has a "J" shaped structure.

[0010] Preferably, the hand-threaded rod passes through the bracket, the cutter is located between the two sets of buckets, and the buckets are in contact with the cutter.

[0011] Preferably, the bottom shape of the cutter is the same as the cross-sectional shape of the bucket.

[0012] Preferably, the scale rod passes through the bracket.

[0013] Preferably, the limiting block is located on the upper side of the bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a hand-cranked threaded rod that is threaded to the bracket, the cutter can be moved up and down inside the bucket by rotating the hand-cranked threaded rod, so as to realize convenient adjustment of the bucket position and depth and avoid the displacement of the cutter. At the same time, by observing the positional relationship between the scale rod and the bracket, the depth of the cutter can be determined, which is convenient for timely adjustment and improves the user experience.

[0015] This invention features an adjustment structure. Before cutting, a hand-operated threaded rod is rotated. The threaded rod is threadedly connected to the support, causing it to move up and down inside the support during rotation. The bottom end of the threaded rod is rotatably connected to the upper end of the cutter. Therefore, the movement of the threaded rod drives the cutter to move up and down inside the bucket, enabling rapid adjustment of the cutter's position relative to the bucket. Furthermore, the threaded connection between the threaded rod and the support prevents the cutter from shifting vertically within the bucket, ensuring a consistent cutting depth. Simultaneously, the vertical movement of the cutter... When cutting, the scale rod moves within the support. By observing the scale on the rod, the distance the cutter protrudes from the bottom of the bucket can be determined, thus indicating the depth of the cut. The limiting block at the top can limit the scale rod, preventing it from falling off the support and affecting its use. During cutting, the concrete scraped off by the bucket can be stably collected inside the bucket under the protection of the cover plate, preventing spillage. By rotating the hand-threaded rod, the bottom surface of the cutter can be made flush with the bottom surface of the bucket. At this time, the device can be used to smooth out uneven areas on the concrete, improving the functionality of the device. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-3 An embodiment of a permeable concrete cutting device provided by this utility model:

[0022] The bucket 1 used in this application is a product that can be purchased directly from the market. Its principle and connection method are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] A permeable concrete cutting device includes: a bucket 1;

[0024] An adjustment structure 2 is installed on the bucket 1. The adjustment structure 2 includes a cover plate 21, which is fixedly installed at the top edge of the bucket 1. A bracket 22 is fixedly connected to the top surface of the cover plate 21. A hand-cranked threaded rod 23 is threadedly connected to the surface of the bracket 22. A cutter 24 is rotatably connected to the bottom end of the hand-cranked threaded rod 23. A scale rod 25 is fixedly connected to the top surface of the cutter 24. A limit block 26 is fixedly connected to the upper end of the scale rod 25. By setting the hand-cranked threaded rod 23 threadedly connected to the bracket 22, the cutter 24 can be moved up and down inside the bucket 1 by rotating the hand-cranked threaded rod 23, so as to realize convenient adjustment of the depth of the bucket 1 and avoid displacement of the cutter 24. At the same time, by observing the positional relationship between the scale rod 25 and the bracket 22, the depth of the cutter 24 can be determined, which is convenient for timely adjustment and improves the user experience.

[0025] Furthermore, two sets of bucket 1 and cover plate 21 are provided respectively. Bucket 1 has a "J" shaped structure. When bucket 1 moves to the left, it can level the concrete. When bucket 1 moves to the right, it can smooth the concrete, thus improving the functionality of the device.

[0026] Furthermore, the hand-operated threaded rod 23 passes through the bracket 22, and the cutter 24 is located between the two sets of buckets 1. The buckets 1 are in contact with the cutter 24, and the two sets of buckets 1 provide limiting guidance for the movement of the cutter 24 to prevent the cutter 24 from rotating.

[0027] Furthermore, the bottom shape of the cutter 24 is the same as the cross-sectional shape of the bucket 1. When the cutter 24 is stored inside the bucket 1, the bottom surface of the cutter 24 can be flush with the bottom surface of the bucket 1. At this time, moving the bucket 1 to the right can smooth the concrete and improve the functionality of the device.

[0028] Furthermore, the scale rod 25 passes through the bracket 22. When the cutter 24 moves, it can drive the scale rod 25 to move. By observing the positional relationship between the scale rod 25 and the bracket 22, the depth of the cutter 24 can be determined, which is convenient for timely adjustment and improves the user experience.

[0029] Furthermore, the limiting block 26 is located on the upper side of the bracket 22. The limiting block 26 can limit the scale rod 25 at the upper end to prevent the scale rod 25 from falling off the bracket 22 and affecting its use.

[0030] Working principle: Before cutting, rotate the hand-threaded rod 23. The hand-threaded rod 23 is threadedly connected to the bracket 22. Therefore, when the hand-threaded rod 23 rotates, it will move up and down inside the bracket 22. The bottom end of the hand-threaded rod 23 is rotatably connected to the upper end of the cutter 24. Therefore, when the hand-threaded rod 23 moves, it will drive the cutter 24 to move up and down inside the bucket 1, realizing the rapid adjustment of the position of the cutter 24 and the bucket 1. Since the hand-threaded rod 23 is threadedly connected to the bracket 22, it can prevent the cutter 24 from moving up and down inside the bucket 1, which can ensure that the cutting depth is consistent. At the same time, when the cutter 24 moves up and down, it will drive the scale rod 25 to move inside the bracket 22. By observing the scale on the scale rod 25, the distance of the cutter 24 protruding from the bottom surface of the bucket 1 can be obtained, and the cutting depth can be judged. The limiting block 26 can limit the scale rod 25 at the upper end to prevent the scale rod 25 from falling off the bracket 22 and affecting the use.

[0031] During cutting, the concrete scooped up by the bucket 1 can be stably collected in the bucket 1 under the cover of the cover plate 21, preventing it from spilling out;

[0032] By rotating the hand-threaded rod 23, the bottom surface of the cutter 24 can be made flush with the bottom surface of the bucket 1. At this time, the device can be used to smooth out the unevenness on the concrete, thus improving the functionality of the device.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
