[0003] However, the cutting depth and cutting width of most slotting machines in the prior art are not easy to adjust. The depth and width can only be adjusted by replacing cutting blades of different sizes, which is inconvenient to use. Moreover, the cutting blades are directly exposed to the outside, which can easily cause harm to construction workers due to accidental start-up, and the safety of use is low. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides the following technical solutions: A building wall grooving machine includes a mounting base plate, which is rotatably hinged to a main body. The main body is provided with a wall grooving mechanism for adjusting the grooving width, a depth adjustment mechanism for adjusting the cutting depth, and an auxiliary calibration mechanism. When grooving the wall, the mounting base plate moves along the wall, and the wall grooving mechanism automatically grooves during the movement.

In standby mode, the mounting base plate and the main body are in an open state, at which time the saw blade assembly is hidden. When the front button assembly is pressed, the mounting base plate and the main body are closed, and the saw blade assembly is exposed from the mounting base plate.

[0006] Preferably, the saw blade assembly includes a first saw blade and a second saw blade, and an adjustable length adjustment sleeve is fixedly installed between the first saw blade and the second saw blade.

The present invention sets a wall grooving mechanism and utilizes the mutual cooperation between the saw blade assembly and the drive assembly. During the grooving process, the grooving width can be quickly adjusted without disassembling the saw blade assembly. In addition, the dust-proof brush can effectively block the generated dust and sand, so that the dust and sand are discharged through the dust discharge pipe, which can effectively reduce dust.

[0014] 2. By providing a wall slotting mechanism in the present invention and utilizing the mutual cooperation between the front button assembly and the power-on button, even if the construction worker accidentally touches the power-on button, the saw blade assembly will not rotate, and at this time, the saw blade assembly is in a hidden state.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Embodiment 1. In the prior art, the cutting depth and cutting width of most slotting machines are not easy to adjust. Only by replacing cutting blades of different sizes can the depth and width be adjusted, which is inconvenient to use. Moreover, the cutting blades are directly exposed outside, and it is very easy to cause harm to construction workers due to accidental startup, and the use safety is relatively low. To solve this technical defect existing in the prior art, as Figures 1 - 4 shown, this embodiment proposes a building wall slotting machine that can quickly adjust the slotting width and slotting depth without disassembling the saw blade component 302. The body main body 2 is rotatably hinged on the installation base plate 1 of the slotting machine. The wall slotting mechanism 3 for adjusting the slotting width is provided on the body main body 2, and the depth adjusting mechanism 4 for adjusting the cutting depth is provided on the installation base plate 1. An auxiliary calibration mechanism 5 is arranged on the body main body 2. When slotting the wall, the installation base plate 1 will move along the wall, and during the movement, the wall slotting mechanism 3 will automatically perform slotting. Moreover, during the slotting process, the slotting depth can be adjusted through the depth adjusting mechanism 4.

[0022] In order to be able to quickly adjust the grooving width, a wall grooving mechanism 3 is provided in this embodiment. Specifically, the wall grooving mechanism 3 includes a driving component 301 detachably installed on the body 2. The output end of the driving component 301 is drivingly connected to a saw blade assembly 302. The saw blade assembly 302 includes a first saw blade 3021 and a second saw blade 3022. An adjusting spacer 3023 with adjustable length is fixedly installed between the first saw blade 3021 and the second saw blade 3022. During the grooving process, the size of the grooved body can be adjusted by changing the length of the adjusting spacer 3023. A display screen assembly 303 for displaying the output rotation speed is provided on the driving component 301. A dust exhaust pipe 304 is provided on the body 2, and a dust-proof brush 305 is provided on the mounting base plate 1. The dust exhaust pipe 304 is located above the saw blade assembly 302, and the dust-proof brush 305 is located on one side of the saw blade assembly 302, which can effectively prevent dust and sand particles from flying during work. A front button assembly 306 for controlling the extension or retraction of the saw blade is provided on the body 2. In the standby state, the mounting base plate 1 and the body 2 are in an open state, and at this time the saw blade assembly 302 is in a hidden state. After pressing the front button assembly 306, the mounting base plate 1 will close with the body 2, and at this time the saw blade assembly 302 will be exposed from the mounting base plate 1. A handle is provided on the body 2, and a power-on button 307 for cooperating with the front button assembly 306 is provided inside the handle. After pressing the front button assembly 306 to expose the saw blade assembly 302 first, then pressing the power-on button 307 can power on the machine. Pressing the power-on button 307 alone cannot power on the machine.

[0023] According to the above content, in the standby state, the mounting base plate 1 and the body 2 are in an open state, and at this time the saw blade assembly 302 will be hidden between the body 2 and the mounting base plate 1. During the grooving operation, first, the construction worker will press the front button assembly 306 to extend the saw blade assembly 302, and then press the power-on button 307 to make the driving component 301 rotate.

[0024] Next, the saw blade assembly 302 will rotate rapidly under the action of the driving component 301 (similar to a angle grinder in the prior art). At the same time, the construction worker will push the mounting base plate 1 to move along the predetermined trajectory on the wall, so as to quickly complete the wall grooving operation.

[0025] In addition, when it is necessary to change the grooving width, only the length of the adjusting spacer 3023 needs to be manually adjusted. After the length of the adjusting spacer 3023 is changed, the distance between the first saw blade 3021 and the second saw blade 3022 will also change, so as to quickly adjust the grooving width without disassembling and assembling the saw blade assembly 302, which is convenient to use.

[0026] In this embodiment, by providing a wall slotting mechanism 3, through the mutual cooperation between the saw blade assembly 302 and the drive assembly 301, during the slotting process, the slotting width can be quickly adjusted without disassembling the saw blade assembly 302. Moreover, the dust-proof brush 305 can effectively block the generated dust and sand, enabling the dust and sand to be discharged through the dust discharge pipe 304, which can effectively reduce dust. In addition, in this embodiment, by providing a wall slotting mechanism 3, through the mutual cooperation between the front button assembly 306 and the power-on button 307, even if the construction worker accidentally touches the power-on button 307, the saw blade assembly 302 will not rotate, and at this time, the saw blade assembly 302 is in a hidden state. Adopting a double-insurance form can effectively prevent the machine from starting due to accidental touch, greatly improving the safety of use.

[0027] Embodiment 2. In order to be able to quickly adjust the distance between the mounting base plate 1 and the body 2, on the basis of Embodiment 1, as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 shown, this embodiment provides a depth adjustment mechanism 4. Specifically, the depth adjustment mechanism 4 includes a drive runner 401 and an auxiliary runner 402 provided at the lower end of the mounting base plate 1. A spirit level 403 and a drive motor 406 are provided on the mounting base plate 1. The drive motor 406 is in transmission connection with the drive runner 401. When the drive runner 401 rotates under the action of the drive motor 406, it will assist the movement of the machine, achieving the effect of saving time and effort. The body 2 is rotatably connected with an adjustment knob 404, and a cam assembly 405 is coaxially and fixedly installed on the adjustment knob 404. A columnar protrusion matching the cam assembly 405 is fixedly installed on the mounting base plate 1. When the cam assembly 405 rotates, it will make the mounting base plate 1 and the body 2 open at a certain angle through the cooperation with the columnar protrusion, thereby adjusting the exposed part of the saw blade assembly 302.

[0028] According to the above content, during the slotting construction, the drive runner 401 will rotate under the action of the drive motor 406, and when the drive runner 401 rotates, it will provide a certain power for the movement of the machine, thereby achieving the effect of saving time and effort.

[0029] Moreover, when it is necessary to adjust the slotting depth, the construction worker will turn the adjustment knob 404 to make the cam assembly 405 rotate. As Figure 6 shown, when the cam assembly 405 rotates, it will adjust the distance between the mounting base plate 1 and the body 2 through the cooperation with the columnar protrusion. The larger the distance, the less the exposed part of the saw blade assembly 302, and the shallower the slotting depth. The smaller the distance, the more the exposed part of the saw blade assembly 302, and the deeper the slotting depth.

[0030] In addition, during the moving grooving process, the level bubble 403 will always monitor the levelness of the installation base plate 1, thereby ensuring the accuracy of the grooving.

[0031] This embodiment sets a depth adjustment mechanism 4, and utilizes the mutual cooperation between the adjustment knob 404 and the cam assembly 405 to quickly adjust the distance between the mounting base 1 and the body 2. The greater the distance, the shallower the groove depth, and the smaller the distance, the deeper the groove depth, thereby quickly adjusting the groove depth and being easy to use. Moreover, this embodiment sets a depth adjustment mechanism 4, and utilizes the mutual cooperation between the driving wheel 401 and the level bubble 403 to provide a certain amount of power for the movement of the machine, thereby achieving the effect of saving time and effort, and can also monitor the levelness of the machine, thereby ensuring the accuracy of the grooves.

[0032] Example 3, in order to improve the accuracy of the wall grooving as much as possible, based on the above embodiment, as Figure 1 、 Figure 2 as well as Figure 7 As shown, this embodiment is provided with an auxiliary calibration mechanism 5. Specifically, the auxiliary calibration mechanism 5 includes an auxiliary button 501 arranged on the main body 2. A rotating bent plate 502 is movably installed inside the main body 2. The auxiliary button 501 and the rotating bent plate 502 are fixedly connected. A limiting hook 503 is provided at the lower end of the rotating bent plate 502. A hook plate matching the limiting hook 503 is fixedly installed on the mounting base 1. When the main body 2 and the mounting base 1 are in an open state, the limiting hook 503 and the hook plate are in contact. A laser lamp head 504 for auxiliary straight line cutting is provided on the main body 2. When the machine moves along the wall, the laser lamp head 504 will form a ray of light on the wall. When the light coincides with the preset trajectory, it indicates that the grooving trajectory is correct.

[0033] According to the above content, in the standby state, the limit hook 503 and the hook plate are in contact. At this time, although the saw blade assembly 302 is in a hidden state, the saw blade assembly 302 cannot be installed or removed.

[0034] When the construction worker presses the auxiliary button 501 , the limit hook 503 and the hook plate will be out of contact. At this time, the installation base plate 1 will be completely opened from the fuselage body 2 . Then, the construction worker can disassemble and assemble the saw blade assembly 302 .

[0035] Moreover, during the grooving process, the laser lamp head 504 will form a light beam on the wall that is parallel to the saw blade assembly 302. Construction workers can determine the grooving position based on whether the light beam coincides with the preset trajectory, which can effectively improve the accuracy of grooving.

[0036] In this embodiment, by setting up the auxiliary calibration mechanism 5 and utilizing the mutual cooperation between the rotating bent plate 502 and the laser lamp head 504, the cutting path can be guided, assisting the construction workers to complete the straight-line cutting more precisely, and effectively improving the accuracy of grooving.

[0037] The control mode of the present invention is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in this field. Moreover, the present invention mainly aims to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
