[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-4The utility model provides a kind of road joint cutter of linear walking and accurate cutting depth control, including vehicle body 1, both sides of vehicle body 1 are equipped with moving assembly, moving assembly includes two rotatingly installed in the side wall of vehicle body 1 rotating lever, two track wheels 2 respectively fixedly installed in the end of two rotating levers and the track 3 wound on two track wheels 2, two double-shaft motors are provided in vehicle body 1, two rotating levers in each moving assembly are fixedly connected with the output shaft of two double-shaft motors, i.e.

[0025] The front end of vehicle body 1 is symmetrically fixedly installed with infrared sensor 11, the surface of saw blade cover 26 is equipped with depth sensor 12, the surface of vehicle body 1 is fixedly installed with rectangular plate, the upper surface of rectangular plate is equipped with controller 13, infrared sensor 11 is configured to monitor the deviation condition of joint cutter from preset straight line in real time, and the output end thereof is electrically connected with the input end of controller 13, so that the monitored deviation data can be transmitted to controller 13 in real time, when infrared sensor 11 detects that joint cutter deviates from preset straight line, the generated monitoring data will be quickly transmitted to controller 13, and controller 13 analyzes and processes the data based on preset control logic.

[0026] The output end of controller 13 is electrically connected with the control end of two double-shaft motors respectively, when controller 13 receives deviation data from infrared sensor 11 and judges that deviation correction operation is needed, control signal will be immediately sent to double-shaft motor to start double-shaft motor operation.

[0027] The depth sensor 12 is responsible for monitoring the cutting depth of the cutting saw blade 8 in real time. Similarly, the output end of the depth sensor 12 is electrically connected to the input end of the controller 13, and the change data of the cutting depth can be fed back to the controller 13 in real time. When the cutting depth changes, the data collected by the depth sensor 12 will be transmitted to the controller 13.

[0028] The other output end of the controller 13 is electrically connected to the control end of the mechanical arm 5. Once the controller 13 receives the cutting depth change data fed back by the depth sensor 12 and determines that the cutting depth needs to be adjusted according to the preset algorithm, it will send a control instruction to the mechanical arm 5 to start the mechanical arm 5.

[0029] The infrared sensor 11 can monitor the deviation of the cutting machine from the preset straight line in real time. When the deviation is detected, the controller 13 will automatically adjust the double-shaft motor connected to the rotating rod to make the cutting machine return to the preset straight track. For example, when the left infrared sensor 11 detects an increase in distance, it means that the cutting machine has deviated to the right. The controller 13 will increase the driving force of the left track wheel 2 to make the cutting machine correct to the left. When the cutting machine deviates to the left, the controller 13 will send a signal to increase the driving force of the double-shaft motor of the right track wheel 2 and a signal to reduce the driving force of the double-shaft motor of the left track wheel 2, so that the cutting machine corrects to the right and returns to the preset straight track.

[0030] The depth sensor 12 can monitor the actual cutting depth of the cutting saw blade 8 in real time. The depth sensor 12 feeds back the monitored data to the controller 13, and the controller 13 compares the actual depth with the preset depth. If there is a deviation between the actual depth and the preset depth, the controller 13 will automatically adjust the movement of the mechanical arm 5 with the cutting saw blade 8, so as to achieve the effect of adjusting the height of the cutting saw blade 8 and make the cutting depth reach the preset value.

[0031] The upper surface of the rectangular plate is fixedly provided with a water storage tank 14, and the surface of the placing plate is provided with a water supply assembly for supplying water in the water storage tank 14 to the cutting saw blade 8, which comprises a hollow rod 15 fixedly provided on the surface of the placing plate, a piston rod 16 slidingly and sealingly arranged in the hollow rod 15, and a spray head 17. The surface of the saw blade cover 26 is provided with a mounting rod 18 through a connecting component, which comprises a mounting ring 25 fixedly sleeved on the mounting rod 18 and a connecting rod fixedly provided on the outer wall of the mounting ring 25. One end of the connecting rod is fixedly connected with the surface of the saw blade cover 26. The bottom end of the mounting rod 18 is provided with a water groove, and the spray head 17 is fixedly provided on the bottom end of the mounting rod 18. The surface of the hollow rod 15 is fixedly provided with an inlet pipe 19 and an outlet pipe 20, which are respectively connected with the water storage tank 14 and the mounting rod 18. The inlet pipe 19 and the outlet pipe 20 are respectively provided with a one-way valve. The one-way valve in the inlet pipe 19 is in a direction from the water storage tank 14 to the hollow rod 15, and the one-way valve in the outlet pipe 20 is in a direction from the hollow rod 15 to the water groove. The piston rod 16 is controlled to move transversely and reciprocally through a transmission component, which comprises a reciprocating screw rod 21 horizontally rotatably provided on the surface of the placing plate, a sliding plate 22 threadedly sleeved on the reciprocating screw rod 21, a chain 23, and two sprockets 24 respectively fixedly sleeved on the reciprocating screw rod 21 and the rotating shaft 6. The surface of the sliding plate 22 is fixedly connected with the end of the piston rod 16, and the chain 23 is engaged and wound on the two sprockets 24.

[0032] During the rotation of the cutting saw blade 8 and the cutting of the road, the rotating shaft 6 also rotates, and under the transmission of the two sprockets 24 and the chain 23, the reciprocating screw rod 21 also rotates, and the sliding plate 22 threadedly sleeved on the reciprocating screw rod 21 moves transversely and reciprocally with the piston rod 16, so that the volume in the hollow rod 15 changes from small to large and then from large to small. When the volume is large, the pressure is reduced, and the water in the water storage tank 14 enters the hollow rod 15 through the inlet pipe 19. When the volume is small, the pressure is increased, and the water in the hollow rod 15 enters the mounting rod 18 through the outlet pipe 20 and is sprayed from the spray head 17 to act on the surface of the cutting saw blade 8, thereby achieving the effect of dust suppression, avoiding dust flying during cutting, reducing environmental pollution, enhancing the functionality of the device, and simultaneously eliminating the need for an additional power-driven device for water supply and avoiding additional power costs.
