Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a mud-pushing and dust-proof grooving device with positioning function. Background Technology

[0002] Traditional wall grooving operations often rely on handheld cutting machines or simple grooving equipment, which has significant drawbacks: First, the cutting process generates a large amount of unorganized dust, seriously polluting the construction environment, endangering workers' respiratory health, and making subsequent cleaning difficult. Second, ordinary equipment lacks a precise positioning mechanism, relying on manual marking to control the grooving path, which is prone to skewing or unevenness due to hand tremors or uneven walls, affecting the quality of subsequent conduit laying. Third, the debris generated during grooving requires repeated manual sweeping, which is inefficient. Conventional dustproof designs (such as external dust suction pipes) lack flexibility and cannot adapt to the different needs of different construction sites for wet dust suppression or dry dust collection. Although some existing technologies have equipment with guide wheels, their buffer structure is simple and cannot effectively absorb cutting vibrations, causing the positioning wheels to easily detach from the groove rail and become inaccurate, resulting in insufficient stability.

[0003] Therefore, in order to address the above problems, a mud-pushing, dust-proof, and grooving device with positioning function is now being developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing technologies, which, although a few devices have guide wheels, have simple buffer structures that cannot effectively absorb cutting vibrations, causing the positioning wheels to easily detach from the groove rail and become inaccurate, resulting in insufficient stability, this utility model provides a mud-pushing and dust-proof grooving device with positioning function.

[0005] The technical solution of this utility model is as follows: a mud-pushing and dust-proof grooving device with positioning function, including a connecting shell, a cutting component provided on the left side of the connecting shell, a volute provided on the left side of the connecting shell, a first extension frame slidably connected inside the volute, a second extension frame slidably connected on the first extension frame, a mounting base installed on the right side of the volute, a damper connected to the lower side of the mounting base, a connecting seat installed at the bottom of the damper, a positioning wheel bolted to the bottom of the connecting seat, the positioning wheel being able to be embedded in the pre-cut groove for movement, and a mud-pushing plate provided on the left side of the connecting seat.

[0006] Optionally, the cutting assembly includes a drive motor and a cutting blade, the cutting blade being located inside the connecting housing.

[0007] Optionally, the top of the volute has two pre-drilled holes for installing spraying or vacuuming equipment.

[0008] Optionally, each of the reserved holes is fitted with a sealing element.

[0009] Optionally, the right side of the second extension frame is rotatably connected to two ball bearings, which are used to contact the building wall to reduce friction during movement.

[0010] Optionally, a spring is provided between the damper and the mounting base.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are:

[0012] This utility model achieves a leap in comprehensive performance through integrated design. The pre-reserved hole in the volute allows for flexible switching between spraying and dust collection equipment. Combined with the sealing structure, it forms a highly efficient dust suppression system, significantly reducing construction dust pollution. After the positioning wheel is embedded in the groove, it continuously absorbs cutting vibration and maintains stable guidance under the synergistic effect of the damper-spring buffer system, greatly improving the accuracy of grooving straight lines.

Detailed Implementation

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0020] A mud-pushing and dust-proof grooving device with positioning function, such as Figures 1-5As shown, the device includes a connecting housing 1. A cutting assembly 2 is located on the left side of the connecting housing 1. The cutting assembly 2 includes a drive motor and a cutting blade. The cutting blade is located inside the connecting housing 1. A volute 3 is located on the left side of the connecting housing 1. Two pre-drilled holes 4 are opened on the top of the volute 3. The pre-drilled holes 4 are used to install spraying or vacuuming equipment. Each pre-drilled hole 4 is fitted with a sealing element 5. A first extension frame 6 is slidably connected inside the volute 3. A second extension frame 7 is slidably connected to the first extension frame 6. Two ball bearings 8 are rotatably connected to the right side of the second extension frame 7. The ball bearings 8 are used to contact the building wall to reduce movement friction. A mounting base 9 is installed on the right side of the volute 3. A damper 13 is connected to the lower side of the mounting base 9. A spring 14 is provided between the damper 13 and the mounting base 9. A connecting seat 10 is installed at the bottom of the damper 13. A positioning wheel 12 is bolted to the bottom of the connecting seat 10. The positioning wheel 12 can be embedded in the pre-drilled groove for movement. A pusher plate 11 is located on the left side of the connecting seat 10.

[0021] It should be noted that when the device is started, the connecting housing 1 serves as the core frame supporting all functional components. The cutting component 2 located on the left first activates the drive motor to generate high-speed rotational power, driving the cutting blade to operate at a preset speed inside the connecting housing 1 to cut materials (such as concrete or brick walls), producing debris and dust. The volute 3, as the carrier of the integrated dustproof system, is located on the left side of the connecting housing 1. Its top has two reserved holes 4 to facilitate the flexible installation of spraying equipment (injecting water mist through a water pump to moisten and reduce dust) or vacuum equipment (using a negative pressure vacuum cleaner to collect dust) according to the site environment. When not in use, each reserved hole 4 is sealed by a snap-fit ​​seal 5 to prevent dust leakage, ensuring the cleanliness of the working environment and operational safety. The first extension frame 6 inside the volute 3 is slidably connected to the volute 3, allowing it to extend and retract axially to accommodate different groove depth requirements. For example, the operator can manually push and pull the first extension frame 6 according to the groove depth to be cut. The second extension frame 7 on it further extends slidably to fine-tune the working range. The two ball bearings 8 on the right side of the second extension frame 7 are rotatably connected and roll in contact with the building wall surface when the device moves. Through the ball bearing mechanism, the traditional sliding friction is transformed into low-resistance rolling friction, which significantly reduces the moving resistance and prevents the device from deviating, improving operational stability and work efficiency. The mounting base 9 on the right side of the device is fixed to the volute 3, providing a support point. A spring 14 is provided between the damper 13 installed below it and the mounting base 9. The preload of the spring 14 absorbs the impact and vibration during the cutting process. The damper 13 slowly releases energy to attenuate the inertial momentum when the device moves. The bottom of the damper 13 is connected to the connecting base 10 by a threaded bolt. The positioning wheel 12 at the bottom of the connecting base 10 is embedded in the grooved track (such as a pre-completed base) before work. (In the guide groove), as the device moves forward as a whole, the positioning wheel 12 rolls along the groove wall, guiding the device to move precisely in a straight line, avoiding blade deflection and achieving high-precision positioning. At the same time, the pusher plate 11 on the left side of the connecting seat 10 pushes out the cutting debris and mud generated at the rear of the blade in real time, preventing accumulation from affecting the cutting depth and device movement. The pusher action keeps the groove surface clean, ensuring smooth subsequent processes such as wire or pipe laying. The entire working process is carried out continuously: the operator first selects to install spray or vacuum equipment at the reserved hole 4 and seals the unused hole, starts the drive motor to make the cutting blade rotate at high speed to cut into the material, and selects to spray water mist or vacuum to reduce dust flying at the same time. The volute 3 collects residual debris. After the first and second extension frames 7 are adjusted to the optimal depth, the ball bearing 8 contacts the wall to provide smooth movement support. The positioning wheel 12 is embedded in the groove rail for stable guidance. The spring 14 and damper 13 buffer the cutting reaction force, and the pusher plate 11 continuously pushes away the debris. The device advances at a constant speed along the grooving direction. After the grooving operation is completed, the motor is turned off and the equipment is removed.
