[0042] 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.

[0043] Combination Figures 1-7 As shown, the wall grooving tool of this utility model includes a housing 1, and further includes:

[0044] The driving component 2 is located inside the housing 1 and has two output ends, both of which extend through and out of the housing 1.

[0045] There are at least two cutting blades 3, each located on one of the output ends of the drive member 2, which are driven by the drive member 2 to cut corresponding grooves on the wall surface.

[0046] The crushing component 4 is located on another output end of the driving component 2. Under the drive of the driving component 2, it is used to crush the concrete in two adjacent trenches to open a trench with a certain width.

[0047] Adjustment component 5 is located inside the housing 1 and is connected to drive component 2. It is used to adjust the distance between drive component 2 and the wall to open grooves of different depths.

[0048] During use, the operator can adjust the distance between the drive component 2 and the wall by adjusting component 5, thereby determining the depth of the groove to meet different construction needs. It can accurately cut grooves of the required depth. After adjusting the depth, the drive component 2 is started. Under the drive of the drive component 2, the cutting blade 3 begins to rotate and cuts the corresponding groove on the wall, determining the position of the groove. The other output end of the drive component 2 is equipped with a crushing component 4. After the cutting blade 3 completes the groove cutting, the crushing component 4, under the continuous drive of the drive component 2, crushes the concrete in the two adjacent grooves and removes the concrete between the grooves, finally creating a groove with a certain width and completing the wall grooving operation. The whole process achieves efficient and precise wall grooving through the coordinated cooperation of various components.

[0049] In a preferred embodiment, this utility model can be further configured as follows: Figure 2 , Figure 3 As shown; the driving component 2 includes:

[0050] Mounting base 21 is located inside the housing 1 and has a horizontal mounting surface;

[0051] The drive motor 22 is fixedly mounted on the mounting surface of the mounting base 21;

[0052] A single-input, double-output worm gear reducer 23 is fixedly mounted on the mounting surface of the mounting base 21. It has two output ends and one input end extending to the outside of the housing 1. One output end is connected to the cutting blade 3, and the other output end is connected to the crushing component 4. The output end of the drive motor 22 is connected to the input end of the single-input, double-output worm gear reducer 23. When the wall grooving tool is working, the mounting base 21 serves as the basic support component for the entire drive component 2, located inside the housing 1. Its horizontal mounting surface provides a stable mounting platform for other components. The drive motor 22 is fixedly mounted on the mounting surface of the mounting base 21. When the drive motor 22 is started, it begins to run and output power. Similarly, the single-input, double-output worm gear reducer 23 is also fixedly mounted on the mounting surface of the mounting base 21. It has two output ends and one input end extending to the outside of the housing 1. The output end of the drive motor 22 is connected to the input end of the single-input, double-output worm gear reducer 23. The input ends are interconnected, so the power output from the drive motor 22 is transmitted to the single-input double-output worm gear reducer 23. After receiving the power, the single-input double-output worm gear reducer 23 reduces the power and distributes it to the two output ends through its internal worm gear transmission structure. One output end is connected to the cutting blade 3, driving the cutting blade 3 to rotate, thereby cutting corresponding grooves on the wall. The other output end is connected to the crushing component 4, driving the crushing component 4 to work and crush the concrete in two adjacent grooves to create a groove with a certain width. Through this design, the cutting blade 3 and the crushing component 4 can be driven simultaneously by one drive motor 22, improving the grooving efficiency. Moreover, the reduction function of the single-input double-output worm gear reducer 23 can ensure that the cutting and crushing work is more stable and precise. It should be noted that the specific structure and working principle of the single-input double-output worm gear reducer can be known from existing technology and will not be elaborated here.

[0053] In a preferred embodiment, this utility model can be further configured as follows: Figure 2 , Figure 3As shown; a single-input, double-output worm gear reducer 23 has a first screw 6 welded to one of its output ends, extending through and to the outside of the housing 1. At least two cutting blades 3 are mounted on the outside of the first screw 6. Several washers 7 and fastening nuts 8 are also mounted on the outside of the first screw 6, with the fastening nuts 8 threadedly connected to the first screw 6. Each cutting blade 3 corresponds to two washers 7 and two fastening nuts 8. The two washers 7 and two fastening nuts 8 on each cutting blade 3 are located on the left and right sides of the cutting blade 3, respectively. To allow for flexible adjustment of the spacing between the cutting blades 3, several more washers 7 and fastening nuts 8 are mounted on the outside of the first screw 6, with the fastening nuts 8 threadedly connected to the first screw 6. Each cutting blade 3 corresponds to... Each cutting blade 3 has two washers 7 and two fastening nuts 8, with the two washers 7 and two fastening nuts 8 located on the left and right sides of the cutting blade 3, respectively. During the grooving process, when different widths of grooves need to be created, the operator can first adjust the distance between two adjacent cutting blades 3, move the cutting blade 3 to the appropriate position, place the two washers 7 on the left and right sides of the cutting blade 3, and then place the corresponding two fastening nuts 8 on the left and right sides of the cutting blade 3. By rotating the fastening nuts 8, the two fastening nuts 8 clamp and tighten the cutting blade 3 using their threaded connection with the first screw 6. In this way, by flexibly adjusting the distance between the cutting blades 3, the requirements for creating grooves of different widths can be met.

[0054] In a preferred embodiment, this utility model can be further configured as follows: Figure 3 , Figure 4 As shown; the broken component 4 includes:

[0055] Drive shaft 41, one end of which is connected to the other output end of single-input double-output worm gear reducer 23;

[0056] A transmission box 42 is disposed through the outside of the transmission shaft 41, wherein there are two transmission boxes 42 and there is a certain distance between the two transmission boxes 42.

[0057] The first bevel gear 43 is fixedly installed on the outside of the transmission shaft 41. There are two first bevel gears 43, which are located on the inside of the two transmission boxes 42 respectively.

[0058] A transmission rod 44 is installed through the transmission box 42 and is rotatably connected to the transmission box 42. The number and distribution of the transmission rods 44 are adapted to the transmission box 42.

[0059] The second bevel gear 45 is fixedly installed on one end of the transmission rod 44 located inside the transmission box 42, wherein the second bevel gear 45 meshes with the first bevel gear 43.

[0060] The crushing roller 46 is bolted to the end of the transmission rod 44 located outside the transmission box 42. The outer side of the transmission box 42 is also fixedly connected to the protective cover 10. A first bearing is embedded on the surface of the transmission box 42, and the transmission shaft 41 is fixedly connected to the inner ring of the first bearing to ensure that the transmission shaft 41 will not drive the transmission box 42 to rotate during rotation. At the same time, a second bearing is embedded at the bottom of the transmission box 42, and the transmission rod 44 is fixedly connected to the inner ring of the second bearing to ensure the stability of the transmission rod 44 during rotation. When the single-input double-output worm gear reducer 23 is running, it will drive the transmission shaft 41 to rotate. When the transmission shaft 41 rotates, it will drive the first bearing to rotate. When the bevel gear 43 rotates, the first bevel gear 43 and the second bevel gear 45 mesh with each other, so the rotation of the first bevel gear 43 will drive the second bevel gear 45 to rotate, which in turn drives the transmission rod 44 to rotate. A crushing roller 46 is bolted to the end of the transmission rod 44 located outside the transmission box 42. The rotation of the transmission rod 44 will drive the crushing roller 46 to rotate. When the crushing roller 46 rotates, it can crush the concrete between the two cutting blades 3, thereby forming a trough with a specific width. At the same time, since the crushing roller 46 is connected to the transmission rod 44 by bolts, this connection method makes it convenient to select crushing rollers 46 of different diameters when opening troughs of different widths.

[0061] In a preferred embodiment, this utility model can be further configured as follows: Figure 2 , Figure 5 As shown; the adjusting component 5 includes:

[0062] The frame 51 is fixedly installed on the inside of the housing 1;

[0063] The second screw 52 has one end rotatably connected to the surface of the frame 51, and the other end extends through and to the outside of the housing 1.

[0064] Threaded sleeve 53 is threadedly connected to the outside of second screw 52;

[0065] The drive plate 54 is fixedly installed on the outside of the threaded sleeve 53. When the wall grooving tool is working, the frame 51 serves as a supporting base, fixedly installed on the inside of the housing 1, providing a stable installation position for other components. One end of the second screw 52 is rotatably connected to the surface of the frame 51, and the other end passes through and extends to the outside of the housing 1. This design allows the second screw 52 to rotate freely on the frame 51. The threaded sleeve 53 is threadedly connected to the outside of the second screw 52. When the operator rotates the second screw 52, ​​due to the threaded connection between the threaded sleeve 53 and the second screw 52, ​​the threaded sleeve 53... The screw 53 will move along the length of the second screw 52. When the threaded sleeve 53 moves along the second screw 52, ​​it will drive the drive plate 54 to move, which in turn drives the mounting base 21 connected to the drive plate 54 to move. The mounting base 21 is fixedly installed with components such as the drive motor 22 and the single-head input double-head output worm gear reducer 23. The movement of the mounting base 21 means that the position of the drive component 2 relative to the housing 1 changes, thereby adjusting the distance between the drive component 2 and the wall. In this way, the operator can accurately adjust the groove depth according to the actual construction needs.

[0066] In a preferred embodiment, this utility model can be further configured as follows: Figure 2 , Figure 5 As shown, two guide rods 9 parallel to the second screw 52 are fixedly installed on the inner side of the housing 1. Through holes adapted to the guide rods 9 are opened on the surface of the driving plate 54. The guide rods 9 restrict the movement direction of the driving plate 54, so that it can only move in a straight line along the length direction of the second screw 52, ​​avoiding the driving plate 54 from deviating or shaking during the movement, and ensuring the accuracy of the adjustment component 5 in adjusting the groove depth.

[0067] In a preferred embodiment, this utility model can be further configured as follows: (e.g., 1) Figure 7As shown, a protective cover 10 is fixedly installed on the outside of the housing 1. The protective cover 10 is semi-enclosed on the outside of the cutting blade 3 and the crushing roller 46. A water storage tank 11 located outside the cutting blade 3 is fixedly installed on the inside of the protective cover 10. Several drainage holes 12 are opened on the surface of the water storage tank 11. A filling port 13 is connected to the water storage tank 11, with one end penetrating and extending to the outside of the protective cover 10. The surface of the protective cover 10 is also provided with a notch for the two output ends of the single-head input double-head output worm gear reducer 23 to pass through and move, ensuring that the adjustment component 5 will not be obstructed during adjustment. The protective cover 10 plays a certain protective role during the grooving process, blocking some of the flying debris and protecting the safety of construction personnel and surrounding equipment. When the cutting blade 3 rotates to cut the wall, the water in the water storage tank 11 will be evenly sprinkled into the cutting area through the drainage holes 12. The water combines with the dust generated during the cutting and crushing process, causing the dust to settle, effectively reducing dust flying, improving the construction environment, and reducing the harm to the health of construction personnel.

[0068] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 6 As shown; two protruding ribs 14 are fixedly installed on the outer side of the housing 1, and a gripping part 15 located between the two protruding ribs 14 is sleeved on the outer side of the housing 1. Several rollers 16 that contact the wall surface are also provided on the outer side of the housing 1. The two protruding ribs 14 play a role in positioning and limiting. The gripping part 15 is sleeved between the two protruding ribs 14. The operator can place his hand on the gripping part 15 and hold the wall grooving tool through the gripping part 15. The protruding ribs 14 can prevent the gripping part 15 from sliding freely on the housing 1, ensuring the stability of the operator's hand. The setting of the rollers 16 reduces the friction between the housing 1 and the wall surface, so that the wall grooving tool can move more smoothly on the wall surface, reducing the labor intensity of the operator and improving the efficiency of grooving work. In addition, the contact between the rollers 16 and the wall surface can also play a certain supporting role, ensuring the stability of the equipment during movement.

[0069] The specific working principle of this wall grooving tool is as follows:

[0070] The operator first determines the width of the groove to be opened based on the construction requirements. If different widths of grooves are required, the operator can adjust the spacing of the cutting blades 3 on the outer side of the first screw 6 on one of the output ends of the single-input double-output worm gear reducer 23. Specifically, the operator first adjusts the distance between two adjacent cutting blades 3, then places two shims 7 on the left and right sides of the cutting blades 3 respectively, and then sets the corresponding two fastening nuts 8 on the left and right sides of the cutting blades 3. The operator then clamps and tightens the cutting blades 3 with the two fastening nuts 8 to adjust the distance between the cutting blades 3, thereby determining the width of the groove to be opened.

[0071] Next, if crushing rollers 46 of different diameters are selected to adapt to the opening of troughs of different widths, crushing rollers 46 can be bolted to the end of the transmission rod 44 located outside the transmission box 42 to complete the installation and replacement of crushing rollers 46.

[0072] Afterwards, the operator holds the grip part 15 and places the wall grooving tool stably on the wall to be grooved using several rollers 16 on the outside of the housing 1 that contact the wall surface. The operator then starts the drive motor 22, which drives the single-input double-output worm gear reducer 23 to rotate. One output of the single-input double-output worm gear reducer 23 drives the first screw 6 to rotate, which in turn drives the cutting blade 3 to rotate at high speed, cutting the corresponding grooves on the wall surface. At the same time, the other output of the single-input double-output worm gear reducer 23 drives the transmission shaft 41 to rotate. The first bevel gear 43 on the transmission shaft 41 rotates accordingly. The first bevel gear 43 meshes with the second bevel gear 45, driving the transmission rod 44 to rotate. The crushing roller 46 on the transmission rod 44 rotates, crushing the concrete in two adjacent grooves to create a groove with a certain width.

[0073] During the cutting and crushing process, the water in the water tank 11 inside the protective cover 10 is evenly sprayed onto the cutting area through the water leakage hole 12, reducing dust.

[0074] When the groove depth needs to be adjusted, the operator rotates the second screw 52, ​​and the threaded sleeve 53 moves along the length of the second screw 52. The driving plate 54 moves under the guidance of the guide rod 9, and the driving plate 54 drives the mounting base 21 to move, thereby adjusting the distance between the driving component 2 and the wall surface, so as to open grooves of different depths.
