[0017] The components include: 1. main body of the cutting machine; 2. cutting blade; 3. cover; 4. connecting arm; 5. support wheel; 6. connecting seat; 7. bolt; 8. water supply pipe; 9. cable tie; 10. water guide pipe; 11. water outlet; 12. baffle plate. Detailed Implementation

[0018] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0019] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] In this utility model, such as Figures 1 to 2 As shown, a cutting machine for building construction is provided, including a cutting machine body 1, a cutting blade 2 connected to the cutting machine body 1, and a cover 3 covering the upper side of the cutting blade 2. The cutting machine also includes a connecting arm 4, one end of which is coaxially and rotatably connected to the cutting blade 2, and the other end extends to the front side of the cutting blade 2 to form a water outlet. The water outlet is provided with a support wheel 5. The cutting machine also includes a water outlet 11 provided at the water outlet and a water supply pipe connected to the water outlet 11.

[0024] As shown in the figure, when the cutting machine of this utility model is in use, because the connecting arm 4 and the cutting blade 2 are coaxially arranged, the support wheel 5 always maintains the same distance from the outer edge of the cutting blade 2 during the cutting operation, so that the water outlet 11 and the cutting blade 2 maintain approximately the same distance. During this process, the support wheel 5 always maintains contact with the ground, allowing the connecting arm 4 to automatically swing according to the cutting depth of the cutting blade 2. The water flowing out of the water outlet 11 flows directly into the front side of the cutting blade 2 where it cuts into the ground. The flowing water not only cools the blade, but also pre-wets the cutting blade 2 at the point where it is about to cut in, and fills the cutting blade 2 with water, thereby reducing dust at the cutting point.

[0025] It should be noted that the improvement of this utility model lies in the water supply structure at the position of the cutting blade 2. It does not restrict the improvement of the walking structure (support wheels and frame) and power structure (components driving the cutting blade) of the main body of the cutting machine. Those skilled in the art can flexibly choose the setting method of the main body of the cutting machine when implementing it.

[0026] In a preferred embodiment, more specifically regarding the structure of this utility model, the slitting machine includes a connecting seat 6 connected to the cover 3 via threaded fasteners, and the connecting arm 4 is rotatably connected to the connecting seat 6.

[0027] As shown in the figure, the connecting seat 6 is directly fixed to the cover 3. The end of the connecting arm 4 facing the connecting seat 6 is set in a ring shape. The connecting seat 6 is provided with a mounting groove. The ring structure of the connecting arm 4 is fitted into the mounting groove, thereby realizing the rotatable connection between the connecting arm 4 and the connecting seat 6.

[0028] In a preferred embodiment, more specifically regarding the structure of this utility model, the cover 3 is provided with a threaded hole, and the threaded fastener includes a bolt 7, which engages with the threaded hole.

[0030] In a preferred embodiment, specifically regarding the structure of this utility model, the water supply pipe 8 is fixed to the connecting arm 4 by cable ties 9. As shown in the figure, the water supply pipe 8 is connected to the outside of the connecting arm 4 and secured by cable ties 9, thereby facilitating the connection between the water supply pipe 8 and the connecting arm 4 and preventing damage to the water supply pipe 8 from stones splashed during the cutting process. In the illustrated embodiment, as shown in the figure, the main body 1 of the cutting machine is also equipped with a water tank, which is connected to the water supply pipe 8 and directly supplies water to the water supply pipe 8.

[0032] As shown in the figure, the water guide pipe 10 is positioned between the support wheel 5 and the cutting blade 2, and the water guide pipe 10 connects the two end plates of the support wheel 5.

[0033] In a preferred embodiment, more specifically regarding the structure of this utility model, the water guide pipe 10 is provided with baffles 12 on both sides of the water outlet 11, and the cutting blade 2 is located between the two baffles 12.

[0034] As shown in the figure, by setting up the baffle plate 12, the water flow from the outlet 11 can be guided and constrained, so that the water flowing out of the outlet 11 can be concentrated to contact the cutting blade 2 and flow down to the ground in the middle. It can also reduce the outward dispersion effect of the cutting blade 2 rotation on the water flow, thereby improving the utilization efficiency of the water flow.

[0035] In a preferred embodiment, specifically regarding the structure of this utility model, the distance between the two water baffles 12 is less than or equal to two centimeters.

[0036] In a preferred embodiment, more specifically regarding the structure of this utility model, the radial dimension of the support wheel 5 gradually decreases from the middle to both ends.

[0037] As shown in the figure, this configuration reduces the rotational resistance of the support wheel 5.
