[0049] As a further solution of the present invention, a plurality of evenly distributed third baffles 302 are fixed to the top surface of the inner frame 211, a second positioning column 305 is fixed between the third baffles 302, a fixed block 308 is fixed to one side of the top surface of the inner frame 211, one end of the second positioning column 305 is fixed to a side surface of the fixed block 308, a connecting strip 307 is fixed to one side surface of the movable block 209, one side of the connecting strip 307 is movably engaged with the outer side wall of the second positioning column 305, a plurality of springs 306 are arranged on the outer side wall of the second positioning column 305, one end of the spring 306 is fixed to a side surface of the third baffle 302, and the other end of the spring 306 is fixed to a side surface of the connecting strip 307.

[0051] As a further solution of the present invention, two first positioning columns 303 are fixed on both sides of the top surface of the inner frame 211, the pushing bar 300 is movably connected to the four first positioning columns 303, and a blocking bar 304 is fixed on the top surfaces of two adjacent first positioning columns 303.

[0052] The position of the push bar 300 can be limited by the first positioning column 303 .

[0053] This solution has the following working process: when using an earth pressure shield, start the drive device 102 and the external motor 606, the drive device 102 drives the connecting frame 103 to rotate, the connecting frame 103 rotates to drive the cutter head 104 to rotate, the cutter head 104 crushes and cuts the rock layer, and the cut gravel enters the first shell 100 and the blocking column 101 through the hole on the cutter head 104, the rotation of the cutter head 104 drives the stirring rod 105 to rotate, so that the gravel enters the protection frame 500, and then passes through the gap of several fixed blocking rods 204, and then is driven by the auger 605 and discharged from the discharge pipe 607 to the conveyor 803, and then the conveyor 803 is started to transport the gravel. While starting the external motor 606, the operator As a PLC controller 700, the PLC controller 700 controls a plurality of obstacle detection sensors 502, and the obstacle detection sensors 502 emit lasers. When the obstacle detection sensor 502 detects that an obstacle has not moved for a long time, it means that one side of the plurality of fixed blocking rods 204 is blocked by gravel. The obstacle detection sensor 502 transmits a signal to the PLC controller 700, and the PLC controller 700 controls the servo motor 405 to rotate back and forth. The reciprocating rotation of the servo motor 405 drives the two swing rods 401 to rotate back and forth through the transmission of the gear 404, so that the gravel is crushed by the crushing ball 402 and the triangular cone, and then the gravel enters the inner tube 601 and is driven by the auger 605 to be transported to the conveyor 803.

[0054] When the slurry shield is used, the PLC controller 700 controls the cylinder 309 to start, the output end of the cylinder 309 moves to drive the push bar 300 to move, the push bar 300 moves to push a plurality of special-shaped spring pieces 301 to compress and deform, the special-shaped spring pieces 301 compress and deform to push the moving block 209 to move, the moving block 209 moves to drive the movable blocking rod 205 to move, until a plurality of fixed blocking rods 204 and the movable blocking rod 205 separate the inner frame 211 into the same gap, at which time the spring 306 is stretched, the PLC controller 700 is operated, and the PLC controller 700 controls the electromagnetic valve 9 01 is turned on, the mud pump is started, and then the water pump 800 is started. The water pump 800 transports water from the second connecting pipe 802 to the first connecting pipe 801, and then discharges it into the rock surface that needs shield construction. The driving device 102 and the external motor 606 are started. The driving device 102 drives the connecting frame 103 to rotate, and the rotation of the connecting frame 103 drives the cutter head 104 to rotate. The cutter head 104 breaks and cuts the rock layer. The broken stones and muddy water after cutting enter the first shell 100 and the blocking column 101 through the holes on the cutter head 104. The rotation of the cutter head 104 drives the stirring rod 105 to rotate, so that the sealing column 101 is The muddy water and gravel between the blocking column 101 and the cutter head 104 can be driven, and the gravel is brought into the protective frame 500 at this time, and the sewage pump 902 pumps and discharges the muddy water, fine sand and small gravel between the blocking column 101 and the first shell 100, while the large gravel is blocked by the fixed blocking rod 204 and the movable blocking rod 205. After a period of time, the driving device 102 is temporarily closed, the PLC controller 700 controls the sewage pump 902 and the electromagnetic valve 901 to close, and then starts the external motor 606 to rotate the auger 605, and then the PLC controller 700 controls the cylinder 309 to output The outlet moves upward, so that the special-shaped spring piece 301 is reset. At this time, the spring 306 pulls the moving block 209, so that the movable blocking rod 205 is reset. Since the rock layer structure is evacuated by the mud shield method, the diameter of the large crushed stone produced is smaller than the gap between the two fixed blocking rods 204. At this time, the auger 605 drives the mud and water, and the mud and water drive the large crushed stone through the inner frame 211 and are transported to the conveyor 803 by the auger 605. Then the PLC controller 700 controls the electromagnetic valve 901 to open and the sewage pump 902 to start, and the sewage between the blocking column 101 and the first shell 100 is pumped out. Then the PLC controller 700 controls the output end of the cylinder 309 to move downward, so that the inner frame 211 is divided into equal gaps by the fixed blocking rod 204 and the movable blocking rod 205, and then restarts the drive device 102 and the water pump 800, and repeats the above operation.

By setting the cylinder 309 to reset, the movable blocking rod 205 is reset, and the large gravel blocked by the fixed blocking rod 204 and the movable blocking rod 205 can enter the second outer shell 602 through the gap between the adjacent fixed blocking rods 204, so that the large gravel and the small gravel can be respectively transported into different pipes, avoiding the large gravel from entering the mud discharge pipe 900, causing the mud discharge pipe 900 to be blocked, and affecting the normal discharge of the shield machine.

By means of the obstacle detection sensor 502, the large gravel blocked by the fixed blocking rod 204 can be detected, so that it is convenient to control the rotation of the servo motor 405, so that the crushing ball 402 crushes the large gravel. By means of the protective cover and the partition block 501, when an earth pressure shield is used, during the process of the gravel entering the protective cover being crushed by the crushing ball 402, the crushed gravel will not be quickly mixed with the uncrushed gravel, so that the large gravel can be crushed, thereby avoiding the large gravel blocking the fixed blocking rod 204 and causing the gravel to be unable to enter the second shell 602 for transportation.

[0069] In summary: when using an earth pressure shield, start the drive device 102 and the external motor 606, the drive device 102 drives the connecting frame 103 to rotate, the connecting frame 103 rotates to drive the cutter head 104 to rotate, the cutter head 104 breaks and cuts the rock layer, and the cut gravel enters the first shell 100 and the blocking column 101 through the hole on the cutter head 104, the rotation of the cutter head 104 drives the stirring rod 105 to rotate, so that the gravel enters the protection frame 500, and then passes through the gap of a plurality of fixed blocking rods 204, and then is driven by the auger 605 and discharged from the discharge pipe 607 to the conveyor 803, and then the conveyor 803 is started to transport the gravel, and while starting the external motor 606, the PLC control is operated The PLC controller 700 controls a plurality of obstacle detection sensors 502, which emit lasers. When the obstacle detection sensor 502 detects that an obstacle has not moved for a long time, it means that one side of the plurality of fixed blocking rods 204 is blocked by gravel. The obstacle detection sensor 502 transmits a signal to the PLC controller 700, which controls the servo motor 405 to rotate back and forth. The reciprocating rotation of the servo motor 405 drives the two swing rods 401 to rotate back and forth through the transmission of the gear 404, so that the gravel is crushed by the crushing ball 402 and the triangular cone, and then the gravel enters the inner tube 601 and is driven by the auger 605 to be transported to the conveyor 803.

[0070] When the slurry shield is used, the PLC controller 700 controls the cylinder 309 to start, the output end of the cylinder 309 moves to drive the push bar 300 to move, the push bar 300 moves to push a plurality of special-shaped spring pieces 301 to compress and deform, the special-shaped spring pieces 301 compress and deform to push the moving block 209 to move, the moving block 209 moves to drive the movable blocking rod 205 to move, until a plurality of fixed blocking rods 204 and the movable blocking rod 205 separate the inner frame 211 into the same gap, at which time the spring 306 is stretched, the PLC controller 700 is operated, and the PLC controller 700 controls the electromagnetic valve 9 01 is turned on, the mud pump is started, and then the water pump 800 is started. The water pump 800 transports water from the second connecting pipe 802 to the first connecting pipe 801, and then discharges it into the rock surface that needs shield construction. The driving device 102 and the external motor 606 are started. The driving device 102 drives the connecting frame 103 to rotate, and the rotation of the connecting frame 103 drives the cutter head 104 to rotate. The cutter head 104 breaks and cuts the rock layer. The broken stones and muddy water after cutting enter the first shell 100 and the blocking column 101 through the holes on the cutter head 104. The rotation of the cutter head 104 drives the stirring rod 105 to rotate, so that the sealing column 101 is The muddy water and gravel between the blocking column 101 and the cutter head 104 can be driven, and the gravel is brought into the protective frame 500 at this time, and the sewage pump 902 pumps and discharges the muddy water, fine sand and small gravel between the blocking column 101 and the first shell 100, while the large gravel is blocked by the fixed blocking rod 204 and the movable blocking rod 205. After a period of time, the driving device 102 is temporarily closed, the PLC controller 700 controls the sewage pump 902 and the electromagnetic valve 901 to close, and then starts the external motor 606 to rotate the auger 605, and then the PLC controller 700 controls the cylinder 309 to output The outlet moves upward, so that the special-shaped spring piece 301 is reset. At this time, the spring 306 pulls the moving block 209, so that the movable blocking rod 205 is reset. Since the rock layer structure is evacuated by the mud shield method, the diameter of the large crushed stone produced is smaller than the gap between the two fixed blocking rods 204. At this time, the auger 605 drives the mud and water, and the mud and water drive the large crushed stone through the inner frame 211 and are transported to the conveyor 803 by the auger 605. Then the PLC controller 700 controls the electromagnetic valve 901 to open and the sewage pump 902 to start, and the sewage between the blocking column 101 and the first shell 100 is pumped out. Then the PLC controller 700 controls the output end of the cylinder 309 to move downward, so that the inner frame 211 is divided into equal gaps by the fixed blocking rod 204 and the movable blocking rod 205, and then restarts the drive device 102 and the water pump 800, and repeats the above operation.

[0071] The position of the movable blocking rod 205 when it is reset is the initial position of the movable blocking rod 205. Fig.10 In the positional relationship shown in , the movable blocking rod 205 is in close contact with the fixed blocking rod 204.

[0072] The driving device 102, servo motor 405, obstacle detection sensor 502, external motor 606, PLC controller 700, water pump 800, conveyor 803, electromagnetic valve 901 and sewage pump 902 can all be purchased on the market. They are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
