[0037] In order to have a clearer understanding of the technical features, objects and effects of the utility model, the specific implementation manners of the utility model will be explained by referring to the drawings.

[0038] As shown in Figures 1 to 5 the embodiment, a shaft tunneling machine is provided, which comprises:

[0039] Rotary device 1;

[0040] Excavating device 2 is arranged at the bottom of the rotating inner ring 11 of the rotary device 1 and comprises an excavating head 22 which can swing;

[0041] Slagging device 3 is arranged at the bottom of the rotating inner ring 11 and comprises a bucket 31 which can swing and a slag suction pipeline 37 which is used for sucking slag, and the bucket 31 can cooperate with the bucket 4 to discharge slag.

[0042] The rotary device 1 comprises a fixed outer ring 12 and a rotating inner ring 11 capable of relative rotation, and the specific structure is the existing structure. When excavating, after the rotary device 1 with the excavating device 2 and the residue discharging device 3 is lowered to a certain depth, the excavating head 22 of the excavating device 2 is inserted into the excavation surface to a certain depth, and the rotary device 1 is rotated to drive the excavating device 2 to rotate by means of the swing of the excavating head 22, so as to comprehensively excavate the excavation surface. At the same time of the excavating of the excavating device 2, the residue discharging device 3 can simultaneously perform residue discharging operation, and the excavating bucket 31 can load a part of the rock residue into the bucket 4, and cooperate with the bucket 4 to discharge the residue, and on the other hand, the excavating bucket 31 can gather the residue, which is more beneficial to the suction residue pipeline 37 to suck the rock residue on the excavation surface to the corresponding position for treatment.

[0043] Therefore, the shaft tunneling machine in the embodiment can realize the purpose of excavating a large-diameter shaft by a small cutter head through the cooperation of the excavating device 2 and the residue discharging device 3 arranged at the bottom of the rotary device 1, and the excavating of the excavating device 2 and the residue discharging of the residue discharging device 3 can be simultaneously performed, and the cooperation of the excavating bucket 31 and the suction residue pipeline 37 realizes efficient residue discharging and improves the construction efficiency.

[0044] In the specific implementation mode, the excavating device 2 further comprises a main arm 21 and an excavating driving mechanism, two ends of the main arm 21 are respectively connected with the bottom of the rotating inner ring 11 and the excavating head 22, and the excavating driving mechanism can at least drive the excavating head 22 to swing.

[0045] Specifically, the excavating driving mechanism can at least drive the excavating head 22 to swing along the radial direction of the rotary device 1, so as to comprehensively excavate the excavation surface. Referring to Figure 3 and Figure 4 The excavating driving mechanism comprises a first excavating driving mechanism 23, the first excavating driving mechanism 23 is connected with the rotating inner ring 11 and the main arm 21, and can drive the main arm 21 to swing around a first horizontal line parallel to the corresponding diameter direction of the rotary device 1, so that the main arm 21 swings along the radial direction of the rotary device 1, and in turn drives the excavating head 22 to swing along the radial direction.

[0046] Further, the excavating driving mechanism further comprises a second excavating driving mechanism 24, the second excavating driving mechanism 24 is connected with the main arm 21 and the excavating head 22, and can at least drive the excavating head 22 to swing around a second horizontal line and a third horizontal line perpendicular to each other; the first horizontal line is parallel to the second horizontal line or the third horizontal line.

[0047] Specifically, the upper end of the main arm 21 is hingedly connected to the rotating inner ring 11, and the first excavation driving mechanism 23 is a first excavation telescopic cylinder, the upper end and the lower end of which are hingedly connected to the rotating inner ring 11 and the main arm 21 respectively. The hinged axis corresponding to the hingedly connected position of the upper end of the main arm 21 to the rotating inner ring 11 constitutes the above-mentioned first horizontal line. The extension and retraction amount of the first excavation telescopic cylinder can be controlled to control the pitching movement of the main arm 21 around the first horizontal line, so as to adjust the up-down movement position of the excavation head 22.

[0048] The lower end of the main arm 21 is hingedly connected to the excavation head 22 in a cross shape or a spherical shape; the second excavation driving mechanism 24 includes a plurality of second excavation telescopic cylinders 241 surrounding the outer periphery of the main arm 21, one end of each of the second excavation telescopic cylinders 241 is hingedly connected to the excavation head 22 or the main arm 21 in a hooke joint, and the other end is hingedly connected to the main arm 21 or the excavation head 22 in a spherical joint or a hooke joint. That is, the lower end of the second excavation telescopic cylinder 241 is hingedly connected to the excavation head 22 in a hooke joint, and the upper end thereof is hingedly connected to the main arm 21 in a spherical joint or a hooke joint; or the upper end of the second excavation telescopic cylinder 241 is hingedly connected to the main arm 21 in a hooke joint, and the lower end thereof is hingedly connected to the excavation head 22 in a spherical joint or a hooke joint. The number of the second excavation telescopic cylinders 241 should be greater than or equal to three to meet the requirements of degrees of freedom and rigidity; the extension and retraction amount of all the second excavation telescopic cylinders 241 can be simultaneously controlled to accurately adjust the swing angle of the excavation head 22.

[0049] Generally, the upper end of the main arm 21 is hingedly connected to the rotating inner ring 11 in a flat joint, and the two ends of the first excavation telescopic cylinder are also hingedly connected to the rotating inner ring 11 and the main arm 21 in a flat joint; other hinged connection forms can also be used according to requirements.

If the other end is hingedly connected to the main arm 21 or the excavation head 22 in a spherical joint, a hydraulic cylinder, an oil cylinder driven by a ball screw or an electric cylinder can be selected.

The hinged axis corresponding to the hinged position of the bucket 31 and the bucket arm 32 constitutes the fifth horizontal line mentioned above. By the extension and retraction of the third slagging telescopic cylinder, the swinging of the bucket 31 around the fifth horizontal line relative to the bucket arm 32 can be controlled.
