[0034] In order to more clearly explain the technical solution of the present invention, it is described in the form of specific embodiments below.

[0035] Example 1

[0036] like Figure 1-Figure 3 As shown, this embodiment provides a shield machine cutter disc soil flushing equipment, including an equipment body 1 and a cleaning mechanism 2 arranged on the equipment body 1, the cleaning mechanism 2 includes a cleaning scraper and a lifting assembly 21 that drives the cleaning scraper 217 to move, wherein the cleaning scraper 217 is in contact with the cutter disc body 12 of the shield machine body 11.

[0037] The lifting assembly 21 includes a fixed box 13 arranged on the device body, the inner wall of the fixed box 13 is rotatably connected to a worm 211, one end of the worm 211 is fixedly connected to a servo motor 212 fixedly connected to the outer wall of the fixed box 13, the outer wall surface of the worm 211 is meshed with a worm wheel 213 rotatably connected to the inner wall of the fixed box 13, the outer wall of the worm wheel 213 is fixedly connected to a threaded rod 214 rotatably connected to the outer wall of the device body 1, the outer wall of the threaded rod 214 is threadedly connected to a lifting rod 215, the lifting rod 215 is framed in a fixed groove 216, and the surface of the lifting rod 215 is provided with the cleaning scraper 217 adapted to the lifting rod.

[0038] Furthermore, the cross section of the cleaning scraper 217 is triangular, and the lifting rod 215 is in contact with the bottom surface of the cleaning scraper 217 and is arranged parallel to each other.

[0039] Further, the length of the lifting rod 215 is equal to that of the cleaning scraper 217. The cleaning effect can be further enhanced by the stable triangular structure of the cleaning scraper and the arrangement of the cleaning scraper covering all parts of the lifting rod.

[0040] Furthermore, the threaded rod 214 forms a rotating structure through the worm 211 and the worm wheel 213 , which is conducive to the rotation of the worm 211 driving the threaded rod 214 to rotate through the rotation of the worm wheel 213 , thereby realizing the control operation of the sliding of the lifting rod 215 .

[0041] Furthermore, the rotating part at the bottom of the threaded rod 214 and the rotation center of the worm wheel 213 are on the same plane, which is beneficial to realize the control operation of the reciprocating lifting and sliding stability of the lifting rod 215 by setting the rotation center of the threaded rod 214 and the rotation center of the worm wheel 213 on the same plane.

[0042] Furthermore, the lifting rod 215 forms a reciprocating lifting structure through the threaded rod 214 and the fixed groove 216, which is conducive to the rotation of the threaded rod 214 to drive the lifting rod 215 to slide along the inner wall of the fixed groove 216, thereby realizing the control operation of the reciprocating motion of the cleaning scraper 217.

[0043] Example 2

[0044] like Figure 1 , Figure 2 and Figure 4As shown, a shield machine cutter disc soil flushing device proposed in this embodiment 2 is another implementation mode of the present utility model compared to embodiment 1. A water tank 3 is also provided at the bottom of the fixed groove 216, and a water pump body 31 is provided on the upper surface of the water tank 3. The water pump body 31 is connected to a delivery hose 32, and a high-pressure nozzle 34 located on one side of the cutter disc body 12 is provided at the upper end of the delivery hose 32.

[0045] Furthermore, a positioning block 33 penetrating through the outer wall of the delivery hose 32 is welded to the outer wall of the lifting rod 215 to position the delivery hose 32 on the lifting rod 215 .

[0046] Further, there is a gap between the high pressure nozzle 34 and the positioning block 33, and the gap has at least a length. In this way, when there is a certain distance between the two, the high pressure nozzle will not be disturbed when working, and it is more conducive to flushing.

[0047] When the flushing equipment of this embodiment is working, by setting the positioning block 33, it is beneficial to improve the effect of flushing the soil on the surface of the cutter disc and the multi-directional stamping effect on the cutter disc when it is necessary to clean the soil on the surface of the cutter disc through the cleaning equipment. The water pump body 31 can be opened through the connection of the connecting hose, and the water in the water tank 3 is used to flush the cutter disc through the high-pressure nozzle 34. At the same time, through the sliding of the lifting rod 215 and the connection of the positioning block 33, the high-pressure nozzle 34 is driven to adjust the height, so as to realize the control operation of improving the multi-directional flushing effect of the cutter disc surface when the shield machine cutter disc surface is flushed by the flushing equipment.

[0048] Furthermore, an observation window 35 is provided on the surface of the water tank 3. The observation window 35 is located in the middle of the surface of the water tank, which is more conducive to real-time monitoring of the water level in the water tank.

[0049] Furthermore, the material of the observation window 35 is a transparent material, which is conducive to further realizing the control operation of effectively observing the water level in the water tank 3 through the setting of the observation window 35 being a transparent material.

[0050] Furthermore, the cleaning scraper 217 forms a reciprocating cleaning operation between the lifting rod 215 and the cutter disc body 12, which is conducive to the movement of the lifting rod 215 to drive the cleaning scraper 217 to slide along the surface of the cutter disc body 12, thereby realizing a control operation to improve the scraping and cleaning effect of the cutter disc surface when cleaning the soil on the cutter disc surface.

[0051] Furthermore, the high-pressure nozzle 34 forms an adjustment structure with the lifting rod 215 through the delivery hose 32 and the positioning block 33, which is beneficial to drive the high-pressure nozzle 34 and the lifting rod 215 to perform synchronous lifting and lowering movements through the connection of the delivery hose 32 and the limiting of the positioning block 33, thereby realizing the control operation of improving the multi-directional flushing effect of the cutter disc surface when the cutter disc surface of the shield machine is flushed by the flushing equipment.

[0052] The working principle of the flushing equipment of the above embodiment is as follows: First, when the shield machine cutter disc is cleaned by the flushing equipment, in order to improve the effect of flushing the soil on the cutter disc surface, the servo motor 212 can be turned on when cleaning the soil on the cutter disc surface. The rotation of the worm 211 drives the worm wheel 213 to rotate. The rotation of the worm wheel 213 drives the lifting rod 215 to slide along the inner wall of the fixed groove 216 through the rotation of the threaded rod 214. At the same time, the movement of the lifting rod 215 drives the cleaning scraper 217 to perform a reciprocating cleaning motion along the surface of the cutter disc body 12, thereby realizing a control operation to improve the scraping and cleaning effect of the soil on the cutter disc surface when cleaning the soil on the cutter disc surface.

[0053] Finally, when it is necessary to clean the soil on the surface of the cutter disc by cleaning equipment, in order to improve the effect of flushing the soil on the surface of the cutter disc and the multi-directional stamping effect on the cutter disc, the water pump body 31 can be opened through the connection of the connecting hose, and the water in the water tank 3 is used to flush the cutter disc through the high-pressure nozzle 34. At the same time, through the sliding of the lifting rod 215 and the connection of the positioning block 33, the high-pressure nozzle 34 is driven to adjust the height, so as to realize the control operation of improving the multi-directional flushing effect of the cutter disc surface when the shield machine cutter disc surface is flushed by the flushing equipment.

[0054] Finally, it is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the principles and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
