The water flow sprayed by the high-pressure water gun 17 can soften the dregs, is convenient to convey the dregs into the dregs collecting bucket 32 through the conveying pipe 20, and reduces dust.
For the specific structural form of the conveying pipe 20, the invention is preferably an auger conveyor, namely a conveying shaft 23 is rotatably arranged in the conveying pipe 20, a spiral blade 24 is arranged on the conveying shaft 23, and a conveying motor 21 for driving the conveying shaft 23 to rotate is arranged at the rear end of the conveying pipe 20. After the conveying pipe 20 is changed into the auger conveyor, the top of the part of the conveying pipe 20 positioned in the shell 2 can be provided with an open structure, so that dregs can enter the conveying pipe 20 conveniently. Preferably, the conveying pipe 20 should include at least two sets, and be spaced apart along the width direction of the housing 2, so as to improve conveying efficiency.
Further, in order to improve the efficiency of the slag feeding roller 15 in shoveling the slag into the casing 2, the slag removing mechanism 3 may be slidably disposed on the base 1 through a sliding mechanism, and the arrangement direction of the base 1 and the sliding direction of the slag removing mechanism 3 are consistent with the tunneling direction of the TBM. In the process of slag shoveling, the slag removing mechanism 3 can drive the slag conveying roller 15 to move towards the slag pile, so that slag soil is continuously shoveled into the shell 2, compared with manual pushing of the slag soil towards the slag conveying roller 15, the mode is higher in efficiency, and workers only need to pile the slag soil into the moving range of the slag conveying roller 15. In the actual process, each time the TBM is tunneled forward for a certain distance, partial slag piles are generated, workers can transfer adjacent slag piles together in a more actual condition, and then the lifting slag turning device is utilized for centralized transfer. When the device is far away from the slag pile, the device needs to be moved, and the track of the slag transport vehicle is properly prolonged, so that the whole slag transport equipment synchronously moves along with the construction of the TBM.
For the sliding mechanism, the invention adopts the scheme that the base 1 comprises two sliding mechanisms which are respectively arranged at two sides of the slag removing mechanism 3, a set of sliding mechanism is respectively arranged on the two bases 1, the sliding mechanism comprises a fixed block 5 arranged in front of the base 1, a screw rod 14 and a guide rod 16 which are connected between the fixed block 5 and the front end of the base 1 and are arranged in parallel, two sides of the shell 2 are respectively connected with the screw rod 14 at the corresponding side through at least two sliding blocks 13 in a threaded manner and are in sliding connection with the guide rod 16, a first driving motor 6 is arranged on the fixed block 5, and a rotating shaft of the first driving motor 6 is in transmission connection with the screw rod 14 through a meshed first gear 8 and a meshed second gear 7. When in operation, the two sets of sliding mechanisms need to work synchronously, so that the slag removing mechanism 3 can operate stably. The specific working process is that the first driving motor 6 drives the screw rod 14 to rotate positively and negatively through the first gear 8 and the second gear 7, and the sliding block 13 slides back and forth along the guide rod 16 under the combined action of the screw rod 14 and the guide rod 16, so that the slag removing mechanism 3 is driven to move back and forth. During which the first drive motor 6 can be controlled to rotate forwards and backwards through a limit switch. The lengths of the screw 14 and the guide rod 16 are set according to the actual slag pile condition, the capacity of the slag collecting hopper 32 and other site actual conditions, and the condition that the slag removing mechanism 3 can be filled with the slag collecting hopper 32 once in one travel is preferably satisfied. In the back process of the slag removing mechanism 3, a worker can pile up the slag soil in the advancing range of the slag removing mechanism 3, so that the continuous transfer of the slag soil is realized.
Since the conveying pipe 20 moves back and forth along with the slag removing mechanism 3, in order to enable the slag collecting hopper 32 to better receive the slag falling from the slag hole 22, the base 1 between the slag removing mechanism 3 and the hoisting mechanism 4 is further provided with a conveying belt 36, and when the slag removing mechanism 3 moves to the forefront end and the rearmost end, the slag hole 22 of the conveying pipe 20 is located in a range right above the conveying belt 36, and the slag collecting hopper 32 moves back and forth and lifts between the rear end lower part of the conveying belt 36 and the slag conveying vehicle. Since the slag outlet 22 of the conveying pipe 20 is always located in the range right above the conveying belt 36, the conveying belt 36 can stably receive the slag from the conveying pipe 20, and the slag collecting hopper 32 only needs to move in a fixed range and does not need to move together with the slag removing mechanism 3. The length of the conveyor belt 36 may be set according to the site situation, and it is preferable to move the slag hopper 32 a short distance to reach the slag car, so as to further improve the transfer efficiency.
As shown in fig. 9, for the specific structure of the conveyor belt 36, the front and rear conveying rollers 37 of the conveyor belt 36 are rotatably connected with the bases 1 on both sides, a sixth gear 35 is disposed at one end of one of the conveying rollers 37, a third driving motor 33 is disposed beside the sixth gear 35, and a fifth gear 34 meshed with the sixth gear 35 is disposed on the rotating shaft of the third driving motor 33.
For the discharging mode of the slag collecting hopper 32, the invention preferably turns over to slag, specifically, two sides of the top of the slag collecting hopper 32 are respectively provided with a supporting arm 31, a fixed shaft 30 is rotatably arranged between the two supporting arms 31, the two lifting ropes 28 comprise two, and the lower ends of the two lifting ropes 28 are connected with the fixed shaft 30 through lifting hooks 29. When the slag collecting hopper 32 moves above the slag carrier, a worker directly lifts the rear end of the slag collecting hopper 32, so that the slag collecting hopper 32 can rotate around the fixed shaft 30, and slag is poured into the slag carrier, thereby being convenient and quick.
