[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2The utility model provides an embodiment: a descaling device for a shield machine cutter head, comprising a moving plate 1, a bracket 2 is fixedly connected to the upper surface of the moving plate 1, a fixed shell 3 is fixedly connected to the upper surface of the bracket 2, a motor 4 is fixedly connected to one side of the outer wall of the fixed shell 3, a bevel gear 5 is fixedly connected to the output end of the motor 4, a protective shell 6 is fixedly connected to one side of the inner wall of the fixed shell 3, and a left-right symmetrical screw rod 7 is rotatably connected inside the protective shell 6, one end of the two screw rods 7 are both rotatably connected to the inside of the fixed shell 3, and the other ends of the two screw rods 7 are both fixedly connected to the bevel gear 2 5, the bevel gear 25 is meshed with the bevel gear 1 5, the outer wall of the screw rod 7 is rotatably connected to the limit plate 8, one side of the outer wall of the limit plate 8 is fixedly connected to the inner wall of the fixed shell 3, one side of the outer wall of the limit plate 8 is fixedly connected to the limit rod 9, the outer wall of the screw rod 7 is provided with a clamping assembly 10, and a plurality of through holes 11 are opened through the interior of the fixed shell 3; the clamping assembly 10 includes a sliding plate 1001, the sliding plate 1001 is threadedly connected to the outer wall of the screw rod 7, the sliding plate 1001 is slidably connected to the outer wall of the limit rod 9, and one side of the outer wall of the sliding plate 1001 is fixedly connected to an arc plate 1002;

[0024] Specifically, by starting the motor 1 4, the bevel gear 1 5 and the bevel gear 2 25 can be meshed and rotated efficiently. The meshing of the two pairs of bevel gears transmits the power of the motor to the screw 7, so that the screw 7 rotates smoothly inside the fixed shell 3. Next, the rotation of the screw 7 becomes another key link. Due to the rotation of the screw 7, the sliding plate 1001 is driven to slide on the outer wall of the limit rod 9. This design enables the device to remain stable during operation and prevents the device from falling off due to vibration and other reasons. Finally, the operation of the sliding plate 1001 drives the arc plate 1002, so that it is tightly clamped on the outer wall of the shield machine. In this way, the entire stabilization device forms a complete cycle, ensuring its stable performance during use.

[0025] Reference Figure 1 , Figure 2 and Figure 3A ring-shaped pipe 12 is fixedly connected to one side of the outer wall of the fixed shell 3, and a plurality of water spray pipes 13 are fixedly connected to one side of the outer wall of the ring-shaped pipe 12; the plurality of water spray pipes 13 are arranged throughout the fixed shell 3, and a nozzle 14 is fixedly connected to the outer wall of the water spray pipe 13; a connecting rod 15 symmetrical in upper and lower directions is fixedly connected to the inner wall of the fixed shell 3, and a limiting shell 16 is fixedly connected between the two connecting rods 15; a motor 2 17 is fixedly connected to one side of the outer wall of the limiting shell 16, and a transmission shaft 18 is fixedly connected to the output end of the motor 2 17, and a spur gear 19 is fixedly connected to the outer wall of the transmission shaft 18, and a disc brush 20 is fixedly connected to one end of the transmission shaft 18; an annular rack 21 is fixedly connected to the inner wall of the limiting shell 16, and a transmission shaft 2 22 is slidably connected inside the limiting shell 16; a spur gear 23 is fixedly connected to the outer wall of the transmission shaft 22, and the spur gear 23 is meshed with the annular rack 21 and the spur gear 19, and a cleaning roller 24 is fixedly connected to one end of the transmission shaft 22;

[0026] Specifically, the water source is first introduced into the equipment through the annular pipe 12. Through the precise design of the annular pipe 12, the water source can be diverted to the inside of the water spray pipe 13. The design angle of the water spray pipe 13 and the diversified design of the nozzle 14 enable the water flow in the cleaning process to impact the surface of the object at different angles, thereby achieving a better cleaning effect. During the cleaning process, the motor 2 17 plays a key driving role. When the motor 2 17 is started, it will drive the spur gear 1 19 to rotate through the transmission shaft 1 18. This design cleverly utilizes the principle of mechanical transmission, so that the disc brush 20 can clean the center of the cutter head. In this way, not only can the dirt on the surface be removed during the cleaning process, but also some hard-to-reach corners can be cleaned. In order to improve the cleaning efficiency, the equipment also uses an annular rack 21 to limit the spur gear 2 23. This design enables the cleaning roller 24 to revolve while rotating. In this way, the cleaning area of ​​the cleaning roller 24 is greatly increased, thereby improving the cleaning efficiency.

[0027] Working principle: When the device needs to be used to clean the cutter head, the movable plate 1 is pushed to drive the fixed shell 3 to be sleeved on the outside of the cutter head. At this time, the motor 1 4 is started to drive the bevel gear 1 5 to mesh and rotate with the bevel gear 2 25. At this time, the bevel gear 2 25 drives the screw rod 7 to rotate inside the fixed shell 3. At this time, the rotation of the screw rod 7 drives the sliding plate 1001 to slide on the outer wall of the limiting rod 9. At this time, the sliding plate 1001 drives the arc plate 1002 to be clamped on the outer wall of the shield machine, thereby achieving the effect of stabilizing the device and preventing the device from falling off;

[0028] Secondly, when cleaning is needed, the annular pipe 12 is connected to a water source, and the water source is diverted to the inside of the water spray pipe 13 through the annular pipe 12, so as to flush the mud blocks through the water spray pipe 13. At this time, the nozzle 14 is used to achieve the effect of cleaning at different angles. At this time, the motor 2 17 is started, and the spur gear 19 on the outer wall of the transmission shaft 18 is driven to rotate by the motor 2 17. The rotation of the transmission shaft 18 can drive the disc brush 20 to clean the center of the cutter head. At this time, the rotation of the spur gear 19 can facilitate the meshing rotation of the transmission shaft 22 inside the spur gear 23. The movement of the spur gear 23 is limited by the annular rack 21, so as to achieve the effect of driving the cleaning roller 24 to rotate and revolve at the same time. The cooperation of the disc brush 20 and the cleaning roller 24 can achieve the effect of efficient cleaning.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
