A saw blade 13 is provided on the middle of the outer side of the main shaft 7 near the sleeve 8. The saw blade 13 is located between the forearm 10 and the crawler drive wheel 2, and its position is between the two sets of crawlers. The cutting machine originally produced by our company is at the end of the main shaft. The bottom of the inner side of the mounting frame 5 is hinged with a cylinder 6. The output end of the cylinder 6 is connected to the forearm 10. A cross plate is provided in the middle of the inner side of the forearm 10. The output end of the cylinder 6 is hingedly connected to the cross plate for connecting the cylinder 6.

[0020] Furthermore, a fixing plate is provided at the bottom of the gearbox, and the fixing plate is mounted on the top of the mounting frame for mounting the gearbox.

[0021] Furthermore, the mounting bracket 5 is in a U-shape, which facilitates the installation of the gearbox 4 and the cylinder 6 .

[0023] Example:

[0024] When the device is in normal use, the saw blade 13 can be installed to the middle of the main shaft 7. At this time, the machine cutting force can be balanced and the saw blade 13 is not easily offset. When cutting at the edge of the road surface, the saw blade 13 can be installed to the end of the main shaft 7, which is convenient for cutting at the edge of the road surface and is very flexible to use.

[0025] Working principle: When the device is in use, the diesel engine 3 can be started to run, and the diesel engine 3 can drive the gearbox 4 to run. After the speed and torque of the gearbox 4 are adjusted, the pulley A11 can be driven to rotate, and the bearing B16 can prevent the output shaft from being bent and deformed. Then the pulley A11 can drive the pulley B12 through the transmission connection of the belt 14 to rotate the main shaft 7, and then the saw blade 13 is driven to rotate through the main shaft 7 to cut the road surface. At this time, the cylinder 6 is started to run, and the forearm 10 can be pushed to rotate by the extension and contraction of the cylinder 6. The cutting depth of the saw blade 13 can be adjusted, and the movement of the device can be controlled by the crawler drive wheel 2, so that the device can cut the road surface along the specified route.

[0026] Note: This application is mainly aimed at protecting the installation of bearing B to prevent the output shaft from being bent and the cutting disc from being installed close to the center line of the spindle to achieve a straighter cutting line and higher cutting efficiency. It has been manufactured. Our company has made improvements and optimizations based on the original production of double-crawler cutting machines in response to problems arising during on-site operation and relevant customer feedback.
