Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a wall leveling machine equipped with a dust collection structure. Background Technology

[0002] As is well known, wall leveling is a fundamental and crucial construction step in building decoration projects. Its quality directly affects the subsequent decorative effect and the overall construction progress. Traditional wall leveling work relies heavily on manual operation, involving hand sanding and puttying. However, this method is not only labor-intensive and inefficient, but also generates a large amount of dust during the sanding process, seriously polluting the air environment at the construction site, affecting the health of construction workers, and even causing occupational injuries such as respiratory diseases.

[0003] With the continuous improvement of construction mechanization, a number of wall leveling equipment have emerged on the market to replace traditional manual operations and improve construction efficiency and quality. However, most of these equipment still have many shortcomings, such as the lack of an effective dust removal system, which makes it impossible to remove the dust generated during the grinding process, resulting in serious dust pollution on site. At the same time, some equipment has a limited adjustment range and can only adapt to walls of specific heights or sizes, making it difficult to meet diverse construction needs. In addition, the degree of automation is not high, and a lot of manual intervention is still required, which increases construction costs and operational difficulty. Utility Model Content

[0007] Furthermore, the present invention is improved in that the vertical adjustment device includes a slide rail, an electric telescopic rod, and a fixing plate. The electric telescopic rod is installed on the side wall of the control box. The slide rail is vertically slidably installed on the end of the electric telescopic rod away from the control box. The slider is slidably installed on the slide rail. The fixing plate is installed on the top wall of the slide rail. The top output end of the electric telescopic rod and the bottom wall of the fixing plate are also connected.

[0008] Furthermore, the present invention is improved in that the lateral adjustment device includes a groove, a threaded rod, a moving block, and an adjustment motor.

[0011] Furthermore, the present invention is improved in that a power module is installed inside the control box, and the power module is a lithium battery pack.

[0012] Furthermore, an improvement of this utility model is that both the drive motor and the regulating motor are servo motors.

[0013] Compared with the prior art, this utility model provides a wall leveling machine with a dust collection structure, which has the following beneficial effects: This wall leveling machine with a dust-collecting structure, through the design of multiple dust-collecting heads (8) and annular tubes (7), covers the area around the grinding area, ensuring that dust is sucked in without dead corners. The telescopic tubes on both sides can be freely adjusted in length according to the vertical movement of the slider, which improves the overall dust-collecting efficiency and enables the dust-collecting system to adapt to grinding operations at different heights and angles. It is suitable for the construction needs of various walls and wall surfaces. The dust-collecting device is linked with the whole machine control system to realize the automated operation of "grinding and dust collection". The operator can set different suction modes through the controller to adapt to the different dust requirements of the coarse grinding and fine grinding stages, thereby improving the intelligence level of the equipment.

[0017] 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.

[0018] Please see Figure 1-4 A wall leveling machine with a dust-collecting structure includes a base 1, a control box 2, a drive motor 3, a leveling grinding wheel 4, a dust-collecting device, a horizontal adjustment device, a vertical adjustment device, and a moving device. The control box 2 is mounted on the top wall of the base 1 via the horizontal adjustment device. A slider 5 is mounted on one side wall of the control box 2 via the vertical adjustment device. The drive motor 3 is mounted on the side wall of the slider 5. The leveling grinding wheel 4 is mounted on the output end of the drive motor 3. A collection box 6 is mounted on the top of the control box 2. A ring tube 7 is mounted on the side wall of the slider 5 via a bracket. Multiple sets of suction heads 8 are mounted on the end of the ring tube 7 near the leveling grinding wheel 4. The ring tube 7 and the collection box 6 are connected via the suction device. A controller 9 is mounted on the top wall of the collection box 6, and the moving device is mounted on the bottom wall of the base 1. In this embodiment, the operator pushes the entire machine to the vicinity of the wall to be treated. Using the moving device mounted on the bottom of the base 1, the equipment can be flexibly moved to the designated position and close to the wall. The operator then activates the operating interface on the control box 2 and uses the horizontal... The control box 2 is moved horizontally on the base 1 by the adjustment device, so that the leveling wheel 4 is aligned with the target area on the wall. Then, the slider 5 is moved up and down by the vertical adjustment device, which in turn drives the drive motor 3 and the leveling wheel 4 to adjust up and down to meet the needs of wall treatment at different heights. After positioning, the drive motor 3 is started, and in conjunction with the horizontal and vertical adjustment devices, the drive motor 3 drives the leveling wheel 4 to rotate at high speed to grind and level the wall. During the grinding process, the dust suction head 8 is set around the leveling wheel 4 at the end of the annular tube 7, which can promptly suck up the dust particles generated during grinding. The dust enters the dust suction device through the annular tube 7 and is then transported to the collection box 6 at the top for centralized storage. The entire operation process is managed by the controller 9. The operator can set grinding parameters such as pressure, speed, and suction intensity through the controller 9 to achieve intelligent operation. The controller 9 can also monitor the equipment operating status in real time, and has fault warning and automatic shutdown protection functions. The integrated dust suction device can instantly suck up dust during the grinding process, which greatly reduces the concentration of suspended particulate matter in the air and reduces the harm of dust.

[0019] Preferably, in this embodiment, the dust collection device includes a fan 10, a filter 11, a transmission pipe 12, and a telescopic pipe 13. The fan 10 is installed on one side wall of the collection box 6, the filter 11 is installed inside the collection box 6, the transmission pipe 12 is installed at the top of the collection box 6, and two sets of telescopic pipes 13 are installed at the top of the transmission pipe 12. The tops of the two sets of telescopic pipes 13 are respectively connected to the left and right back walls of the annular pipe 7. When the drive motor 3 drives the leveling grinding wheel 4 to start grinding... When polishing the wall, the operator simultaneously activates the vacuum function in the control system. The fan 10 starts running, and after the fan 10 starts running, a stable negative pressure environment is formed in the entire vacuum duct system. The airflow direction is: vacuum head 8 - annular pipe 7 - telescopic pipe 13 - transmission pipe 12 - collection box 6 - filter screen 11 - exhaust port to discharge clean air. The dust particles generated during the polishing process are quickly sucked in by multiple vacuum heads 8 arranged around the polishing disc. The dust enters the annular pipe 7 with the air and is transmitted to the collection box 6 through two telescopic pipes 13. After entering the collection box 6, the dust is intercepted at the filter screen 11 and deposited at the bottom of the box. The purified air is discharged or returned to the external environment through the fan 10. The controller 9 can be set to remind the operator to clean the filter screen 11 and the collection box 6 at regular intervals. If the filter screen 11 is blocked or the airflow decreases, the system can provide feedback information through sensors to remind the operator to perform maintenance.

[0020] Preferably, in this embodiment, the vertical adjustment device includes a slide rail 14, an electric telescopic rod 15, and a fixing plate 16. The electric telescopic rod 15 is installed on the side wall of the control box 2. The slide rail 14 is vertically slidably installed at the end of the electric telescopic rod 15 away from the control box 2. The slider 5 is slidably installed on the slide rail 14. The fixing plate 16 is installed on the top wall of the slide rail 14. Before the equipment starts working, the operator sets the grinding height through the controller 9. The electric slider 5 moves linearly on the slide rail 14 (the working principle of the electric slider 5 and the slide rail 14 is well known in this technical field and will not be described in detail here), realizing the initial bottom-to-top grinding. Height adjustment: When the electric slider 5 reaches the top of the slide rail 14, if it is necessary to further raise the height of the leveling grinding wheel 4 to meet the construction needs of higher walls, the electric telescopic rod 15 is activated, and its output end extends upward, driving the entire slide rail 14 to rise vertically. This causes the slider 5 installed on the slide rail 14 to rise accordingly, realizing the leveling operation of higher walls. This design allows the wall leveling machine to adapt to various height requirements from the ground to higher walls, no longer limited to a certain fixed height range, greatly expanding the application scenarios of the equipment. Operators only need to set the target height through the control system to achieve automatic lifting and lowering adjustment, without the need for manual climbing or external tools to assist in positioning, significantly improving the intelligence level and ease of operation of the equipment.

[0021] Preferably, in this embodiment, the lateral adjustment device includes a groove 17, a threaded rod 18, a moving block 19, and an adjustment motor 20. The groove 17 is formed in the top wall of the base 1. The threaded rod 18 is rotatably installed in the groove 17. The moving block 19 is threaded onto the threaded rod 18. The top wall of the moving block 19 is fixedly connected to the bottom wall of the control box 2. One end of the threaded rod 18 passes through the side wall of the groove 17 and is fitted with the adjustment motor 20. When the equipment needs to be adjusted in the horizontal direction, the operator starts the adjustment motor 20 through the control system. The adjustment motor 20 drives the threaded rod 18. Rotating inside the groove 17, since the moving block 19 and the threaded rod 18 are connected by a threaded fit, when the threaded rod 18 rotates, the moving block 19 will make a linear reciprocating motion in the groove 17 along the axial direction of the threaded rod 18. The top of the moving block 19 is fixedly connected to the control box 2, thereby driving the entire control box 2 and its leveling mechanism to slide smoothly in the left and right directions on the top wall of the base 1, completing the precise adjustment of the lateral position. This device realizes the automatic adjustment function of the leveling mechanism in the horizontal direction, eliminating the need for frequent manual movement of the whole machine, and can cover different areas of the wall, significantly improving construction efficiency and ease of operation.

[0022] Preferably, in this embodiment, two sets of guide rods 21 are symmetrically installed in the groove 17 along the central axis of the threaded rod 18. The moving block 19 and the guide rods 21 are slidably connected. Since the moving block 19 is connected to both the threaded rod 18 and the guide rods 21, during the rotation of the threaded rod 18, the moving block 19 not only moves linearly along the direction of the threaded rod 18, but also slides precisely along the guide rods 21. The guide rods 21 ensure that the moving block 19 always maintains a straight trajectory during the entire lateral movement, avoiding the deviation or vibration that may occur due to the threaded transmission alone.

[0023] Preferably, in this embodiment, the moving device includes casters 22 and a brake assembly 23. Casters 22 are installed at all four corners of the bottom wall of the base 1, and brake assemblies 23 are provided on the casters 22. The brake assembly 23 is adapted to the casters 22. When it is necessary to move the wall leveling machine to different positions, the operator can push the device. Since casters 22 are installed at all four corners of the bottom wall of the base 1, these casters 22 can rotate freely 360 degrees, allowing the device to move easily in any direction, greatly improving the flexibility and mobility of the device. After the device reaches the designated position, in order to ensure that the device will not be displaced due to unexpected external forces (such as collisions or uneven ground) during the construction process, the operator can lock the casters 22 through the brake assembly 23.

[0024] Preferably, in this embodiment, the control box 2 is equipped with a power module 24, which is a lithium battery pack. Compared with traditional wired power supplies, lithium battery packs are lighter and more flexible, reducing the dependence on external power sockets and enabling the equipment to be quickly deployed and put into use in any location. They are particularly suitable for construction sites without a fixed power supply. Lithium batteries have high energy density and can provide a large amount of power in a short time to support high-intensity continuous operation. At the same time, they have a low self-discharge rate and can maintain a high charge even when idle for a long time.

[0025] Preferably, in this embodiment, both the drive motor 3 and the adjustment motor 20 are servo motors. Servo motors can provide very precise position control, which enables the leveling grinding wheel 4 and the horizontal adjustment device to achieve millimeter-level or even finer positioning adjustments. For wall leveling, which requires high precision, servo motors can ensure high precision during the grinding and adjustment process, thereby improving the construction quality.

[0026] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
