As shown in fig. 1 to 4, a stone discharging device for a slurry balance shield machine includes a plurality of stone discharging mechanisms 1 connected in sequence, adjacent stone discharging mechanisms 1 being connected by a mud discharging pipe 2. Wherein the mud pipe 2 is the self structure of slurry balance shield machine, and the different ascending positions department in the length of mud pipe 2 is set up to the mechanism 1 of arranging the stone to maximize utilizes the ability of wrapping up in of mud pipe 2 self, improves the efficiency of arranging the stone and efficiency of construction.
The stone removing mechanism 1 includes a filter unit 10 and a collecting unit 11 communicating with the filter unit 10. The filter unit 10 comprises a filter box 101 connected with the mud discharging pipe 2, a filter grid 102 arranged in the filter box 101 and a stone discharging channel 103 vertically connected to the filter box 101, wherein the mesh diameters of the filter grids 102 in adjacent stone discharging mechanisms 1 are sequentially reduced.
The filter box 101 is consistent with the structure shape of the mud pipe 2, and the two are detachably connected through the water stop quick-release connector 5, and the stone particles carried in mud are different in particle size, so that the stone particles with various particle sizes are different in deposition position, and the stone discharge mechanism 1 is arranged at a proper position according to the requirements so as to intercept the stone particles with different particle sizes. As shown in FIG. 1, the direction indicated by the arrow in the figure is the slurry output direction, and is defined as a stage I stone discharging mechanism, a stage II stone discharging mechanism and a stage III stone discharging mechanism in sequence from left to right. The mud is discharged into the stone discharging mechanism through the mud discharging pipe 2, and is filtered through the filter grid 102 in the filter box 101, so that the mud is separated from the stone. The first-level stone discharging mechanism 1 is arranged before the large-grain-size stone is deposited, and the filter grid 102 in the first-level stone discharging mechanism can intercept the stone with large grain size and allow the stone with grain size smaller than the mesh diameter to pass through; setting a level II stone discharging mechanism 1 before the stone with medium grain size is deposited, wherein the mesh diameter of a filter grid 102 in the level II stone discharging mechanism 1 is properly smaller than that of a filter grid 102 in a level I filter collecting device, and the filter grid 102 in the level II stone discharging mechanism can intercept the stone with medium grain size and allow the stone with grain size smaller than that of the mesh diameter to pass through; the III-level stone discharging mechanism 1 is arranged before the stone with smaller particle size is deposited, the mesh diameter of the filter grid 102 in the III-level stone discharging mechanism is properly smaller than that of the filter grid 102 in the II-level stone discharging mechanism, and the filter grid 102 inside the III-level stone discharging mechanism can intercept the stone with smaller particle size and allow the stone with particle size smaller than that of the grid to pass through. Similarly, the multi-stage stone discharging mechanism 1 can be additionally arranged on the mud discharging pipe 2, and the arrangement position of each stage of stone discharging mechanism 1 and the mesh diameter in the filtering grid 102 can be adjusted according to the actual conditions of engineering.

The inclined partition plate vibration pieces 113 can drive the inclined partition plates 112 to vibrate, so that stones in the collecting box 110 are dispersed and piled up, stones are prevented from being piled up at the inlet of the collecting box 110, and the inclined vibration pieces are multiple, so that the vibration acting force acts on the inclined partition plates 112 more uniformly. The gravity sensor 114 can be used to determine the loading amount of the stone in the collection box 110, so as to determine the time for pulling the collection box 110 out of the hole, and the gravity sensor 114 is provided with a plurality of gravity sensors, so that the accuracy of detecting the loading amount of the stone can be improved.
The filtering unit 10 and the collecting unit 11 are also respectively communicated with a mud returning mechanism 3, and the mud returning mechanism 3 is used for pumping the mud deposited in the collecting box 110 to the mud discharging pipe 2 for discharging.

After the stones are collected, the first valve 34 and the second valve 35 are opened and the mud pump 31 is started, so that the mud in the collecting tank 110 is pumped out of the discharge hole in the mud pipe 2.
When the loading amount of the stone in the collecting box 110 reaches the maximum, the collecting box 110 needs to be dragged out of the hole to carry out placement treatment on the stone, and in order to avoid inconvenient construction caused by falling of the stone filtered in the filtering box 101 into the hole during the process, an opening is formed on the side wall of the stone discharging channel 103, and a closed baffle mechanism 4 for controlling the opening and closing of the stone discharging channel 103 is arranged at the opening.

When the stones are collected, the telescopic rods 42 are contracted to pull the sealing partition plates 43 back into the openings so as to conduct the stone discharging channels 103, and the stones smoothly enter the collecting box 110. When the stones in the collecting box 110 need to be carried out, the telescopic rod 42 stretches out to drive the sealing partition plate 43 to move to the closing convex block 44, so that the stone discharging channel 103 is closed, and the stone discharging device is simple to operate, convenient, quick, stable and reliable.
In order to improve the tightness of the closure of the calculus removing channel 103, the size of the closing partition plate 43 is matched with the cross-sectional area of the calculus removing channel 103 in the invention. The construction inconvenience caused by the fact that stones or mud fall into the construction site due to the overlarge gap between the sealing partition plate 43 and the inner wall of the stone discharging channel 103 is avoided.
In order to facilitate the disassembly and assembly of the connection between the stone removing mechanisms and the disassembly and assembly of the collecting box 110 and the stone removing channel 103, in the invention, the mud discharging pipe 2 and the filtering box 101 and the stone removing channel 103 and the collecting box 110 are connected through the water stopping quick disassembly interfaces 5.
