[0052] A driving mechanism is provided at the bottom of the processing platform 1, which is connected to the cutting mechanism by transmission, and a synchronous connecting rod 25 is provided between the driving mechanism and the dust suction straight pipe 23. The synchronous connecting rod 25 driving mechanism drives the dust suction straight pipe 23 to follow the longitudinal sliding displacement. The driving mechanism includes a second transmission shaft 15 provided at the bottom of the processing platform 1, and a first gear 13 meshing with a third gear 29 is provided at one end of the second transmission shaft 15. A cylindrical cam 14 is provided on the outer side of the second transmission shaft 15, and a one-way ratchet mechanism is provided between the inner side of the cylindrical cam 14 and the second transmission shaft 15. The one-way ratchet mechanism is used to drive the cylindrical cam 14 to follow the rotation when the second transmission shaft 15 rotates in the opposite direction. A limiting slider 31 adapted to the cylindrical cam 14 is provided on the outer side of the first support frame 7. The second transmission shaft 1 5 is also sleeved on the outside of a synchronous connecting rod 25 fixedly connected to the dust suction straight pipe 23, and two groups of limit rings 32 are fixedly sleeved on the outside of the second transmission shaft 15, and the two groups of limit rings 32 are distributed on both sides of the synchronous connecting rod 25. A coupling sleeve 17 is provided at the bottom of the processing platform 1, and a linkage sleeve 34 is installed on the internal bearing of the coupling sleeve 17. The other end of the second transmission shaft 15 is transmission-connected to the linkage sleeve 34, and a plurality of groups of sliding pins 33 are evenly distributed on the outside of the second transmission shaft 15 near one end of the linkage sleeve 34, and a long slide groove matched with the sliding pin 33 is provided on the inner wall of the linkage sleeve 34. A driving motor 16 transmission-connected to the other end of the linkage sleeve 34 is provided at the bottom of the processing platform 1, and a synchronous transmission unit 3 is provided between the linkage sleeve 34 and the driving motor 16.

[0053] The use process of the building material cutting device proposed in this embodiment is as follows: the driving motor 16 is started to rotate slowly in the reverse direction, thereby driving the linkage sleeve 34 connected to the synchronous transmission unit 3 to rotate in the reverse direction, and the second transmission shaft 15 is driven to rotate in the reverse direction through the linkage sleeve 34. At this time, the reverse rotation of the second transmission shaft 15 is engaged by the one-way ratchet mechanism inside the cylindrical cam 14, thereby driving the cylindrical cam 14 to follow the rotation. When the cylindrical cam 14 rotates, it is limited by the limit slider 31, so that the cylindrical cam 14 is longitudinally displaced while rotating, and the displacement of the cylindrical cam 14 drives the second transmission shaft 15 to move longitudinally as a whole;

[0054] The displacement of the second transmission shaft 15 drives the dust suction straight pipe 23 connected to the synchronous connecting rod 25 to be displaced, so that the dust suction straight pipe 23 is released from the engagement with the dust outlet port 27. The displacement of the dust suction straight pipe 23 drives the limiting rod 24 connected to the connecting frame 10 to follow the displacement, so that the limiting rod 24 is released from the engagement with the limiting groove 28. As the limiting rod 24 is displaced, the compression spring 26 generates a rebound force.

[0055] Furthermore, the rotating disk 4 drives the first transmission shaft 6 to rotate, and the rotation of the first transmission shaft 6 drives the second bevel gear 19 and the fourth gear 30 to rotate respectively;

[0056] The rotation of the fourth gear 30 drives the fifth gear 35 meshing therewith to rotate, thereby driving the mounting plate 9 outside the first mounting shaft 8 to rotate as a whole, and adjusting the position of the required cutting blade 2 so that the cutting blade 2 required for cutting is located at the top position of the mounting plate 9;

[0057] The rotation of the second bevel gear 19 drives the first bevel gear 18 to rotate, and then drives the second gear 21 outside the third transmission shaft 22 to rotate, and the gear ring 20 meshing therewith is driven to rotate by the second gear 21, so that the T-shaped cylinder 40 rotates inside the outer sleeve 38, driving the L-shaped material guide hole 41 to rotate and communicate with the corresponding branch pipe 39;

[0058] During the rotation of the mounting plate 9, each time a group of cutting blades 2 is adjusted and rotated, the L-shaped material guide hole 41 is connected to a group of branch pipes 39 accordingly, so that the debris generated when cutting building materials of different materials enters different collection grooves, realizing the function of classification and processing;

[0059] When the adjustment is completed, the drive motor 16 is started to rotate in the forward direction at a slow speed, thereby driving the second transmission shaft 15 to rotate forward as a whole. At this time, the second transmission shaft 15 is not engaged with the one-way ratchet mechanism, so that the cylindrical cam 14 cannot be driven to rotate. However, at this time, the limit rod 24 is affected by the rebound force of the spring 26, thereby driving the limit rod 24 to reset in the opposite direction and engage with the limit groove 28. The displacement of the limit rod 24 drives the dust suction straight pipe 23 connected to the connecting frame 10 to follow the displacement, so that the dust suction straight pipe 23 and the corresponding dust outlet port 27 engage with each other. When the dust suction straight pipe 23 is displaced, the second transmission shaft 15 connected to the synchronous connecting rod 25 is driven to move in the opposite direction through the dust suction straight pipe 23, thereby causing the cylindrical cam 14 on the outer side of the second transmission shaft 15 to rotate in the opposite direction. At the same time, the displacement of the second transmission shaft 15 drives the first gear 13 and the third gear 29 to mesh with each other, thereby completing the function of adjusting the adapted cutting blade 2 for cutting when cutting different building materials, optimizing the existing disassembly and replacement method of the cutting blade, and improving the replacement efficiency;

[0060] Furthermore, the driving motor 16 is started to rotate at a high speed. At this time, the one-way ratchet mechanism inside the cylindrical cam 14 is not engaged with the second transmission shaft 15, and the spring 26 has no rebound force, so that the driving force of the driving motor 16 drives the first gear 13 at one end of the second transmission shaft 15 to rotate at a high speed, and then drives the third gear 29 to rotate at a high speed, so that the cutting blade 2 rotates at a high speed to cut the building materials;

[0061] During the cutting process, the dust collection bin 5 is started to generate suction, so that the debris generated during the cutting process is transported to the corresponding collection slot inside the dust collection bin 5 through the installation groove 12, the dust outlet port 27, the dust straight pipe 23, the hose 37, the L-shaped material guide hole 41, and the branch pipe 39 in sequence, thereby realizing the classified collection and processing of debris from different construction materials.

[0062] Example 2

[0063] like Figures 1 to 5 , Fig.12 , Fig.13 As shown, a method for cutting building materials, the cutting method steps are as follows:

[0064] Step 1: First, start the driving mechanism to rotate slowly in the reverse direction, and use the power provided by the driving mechanism to drive the dust suction straight pipe 23 connected to the synchronous connecting rod 25 to slide longitudinally, thereby pulling the dust suction straight pipe 23;

[0065] Step 2: Then, the displacement of the dust suction straight pipe 23 synchronously drives the positioning mechanism to follow the displacement, thereby releasing the positioning of the mounting plate 9 and closing the driving mechanism at the same time. At this time, the displacement of the positioning mechanism generates a rebound force;

[0066] Step 3: Further, the L-shaped material guide hole 41 is rotated and connected to the corresponding branch pipe 39 by rotating the adjusting mechanism, and the mounting plate 9 is rotated as a whole to adjust the position of the required cutting mechanism;

[0067] Step 4: Furthermore, the driving mechanism is started to rotate slowly in the forward direction, and the dust suction straight pipe 23 is driven to reset by the rebound force of the positioning mechanism, and the mounting plate 9 is positioned by the positioning mechanism, so that the dust suction straight pipe 23 corresponds to the mounting plate 9, and the driving mechanism is connected to the cutting mechanism by transmission;

[0068] Step 5: Finally, the building materials to be cut are placed on the top surface of the processing platform 1, and the driving mechanism is started to rotate in the forward high speed to drive the cutting mechanism to cut the building materials.

[0069] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
