Example 1

As shown in fig. 1-4, the utility model provides a quick unearthing cutter for shield constructs machine, including circular shape base plate 1, be equipped with the centre bore on the base plate 1, the drive shaft 11 is connected to the centre bore internal rotation, and drive shaft 11 passes centre bore fixed

connection blade disc

2, and 2 one side fixed connection cutting knife tackle 21 of blade disc can make blade disc 2 drive cutting knife tackle 21 rotate with the drive shaft 11 with the benchmark through drive shaft 11 to stretch into the underground and cut the soil body. The cutter head 2 and the cutter group 21 are both in the prior art, and the specific structure and the connection mode are not described herein again.

The outer wall of the driving shaft 11 is sleeved and fixed with a main toothed ring 3, six rotating holes are formed in the base plate 1, the rotating holes are uniformly formed by taking the center of the base plate 1 as a reference, a rotating shaft 4 is rotatably connected in each rotating hole, a slave toothed ring 41 is sleeved and fixed on the outer wall of each rotating shaft 4, and each slave toothed ring 41 is meshed with the main toothed ring 3; the rotation of the driving shaft 11 can drive the main gear ring 3 to rotate synchronously, and the main gear ring 3 can drive the six auxiliary gear rings 41 to rotate, so that the rotating shaft 4 can rotate in the rotating hole. Be equipped with between base plate 1 and the blade disc 2 and keep off native ring 5, keep off native ring 5 one side fixed connection in base plate 1 one side, blade disc 2 one side is equipped with annular slot, keeps off native ring 5 opposite side grafting cooperation and connects in annular slot. The cutter head 2 can rotate along the outer wall of the retaining ring 5 through the annular slot, and the cut soil body falls to the retaining ring 5 in the working process of the cutting knife set 21; every axis of rotation 4 all passes and rotates hole fixed connection device of dialling native, dial native device and include stand pipe 6, the equal fixed connection of stand pipe 6 is in 4 one ends of axis of rotation, sliding connection guide bar 61 in the stand pipe 6, guide bar 61 one end fixed connection spherical block 62, guide bar 61 other end fixed connection dial native board 63, spring 64 is cup jointed to the guide bar 61 outer wall, spring 64 fixed connection is between spherical block 62 and stand pipe 6,

spherical block

62 and 5 butt settings of retaining ring. When the rotating shaft 4 rotates in the rotating hole, the rotating shaft 4 can drive the guide pipe 6 to synchronously rotate by taking the rotating shaft 4 as a reference, so that the guide pipe 6 drives the spherical blocks 62 and the soil shifting plates 63 at the two ends of the guide rod 61 to rotate; the soil shifting plate 63 can shift soil accumulated on the retaining ring 5 when turning to the retaining ring 5, and the soil shifting plate 63 can guide the shifted soil to the outer side of the base plate 1 along with the continuous rotation of the soil shifting plate 63. When the spherical block 62 turns to the retaining ring 5, the spherical block will contact with the retaining ring 5, and the retaining ring 5 will provide a thrust force to the spherical block 62, so that the guide rod 61 pushes the soil shifting plate 63 to move towards the outer side of the base plate 1, so that the soil shifting plate 63 guides the shifted soil to a farther position on the outer side of the base plate 1, and the spring 64 is in a compressed state; after the spherical blocks 62 are separated from the retaining ring 5, the guide rod 61 carries the spherical blocks 62 to move reversely along the guide tube 6 under the action of the spring 64, so that the soil deflector 63 can again deflect the soil accumulated on the retaining ring 5 when turning to the retaining ring 5.

The side wall is equipped with a plurality of soil channels 7 on the blade disc 2, leads soil channel 7 and uses the blade disc 2 center as the even setting of benchmark, and the tank bottom of every soil channel 7 that leads all is equipped with inclined plane 71, and every inclined plane 71 all sets up towards retaining ring 5. After the cutting knife set 21 cuts the soil, the cut soil can be guided to the soil retaining ring 5 along the inclined plane 71 of the soil guiding groove 7, so that the soil shifting plate 63 can shift the cut soil out of the base plate 1. The outer wall of the substrate 1 is sleeved and fixed with a protection ring 8, the protection ring 8 can protect the main toothed ring 3, the auxiliary toothed ring 41 and the driving shaft 11, and the influence of broken soil on the main toothed ring 3, the auxiliary toothed ring 41 and the driving shaft 11 to the rotation is avoided.

During the use, be connected drive shaft 11 with the drive setting of shield structure machine, drive shaft 11 drive blade disc 2 drives cutting knife tackle 21 and rotates, thereby stretch into the underground and cut the soil body, cutting knife tackle 21 is at the tunnelling in-process of underground cutting soil body, the soil body of being cut can fall to retaining ring 5 along leading soil groove 7 on, at drive shaft 11 pivoted in-process, can drive the stirring board 63 in the stirring device and also rotate in step, stirring board 63 can be continuous stir the soil body on retaining ring 5 and lead the base plate 1 outside, thereby reduce soil body pressure, in order to do benefit to the high-efficient work of shield structure machine.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
