Description

Technical Field

[0001] The invention relates to the technical field of slag sampling, and in particular to a slag sampling device used in a TBM excavation process. Background Art

[0002] TBM is a tunnel boring machine used for excavating rock strata. During the TBM excavation process, it is necessary to sample the slag during the excavation process, so that construction personnel can obtain information on the lithology and geological conditions of the strata and provide improvement measures for subsequent construction.

[0003] A patent document with an existing application number of CN2016211067796 and a publication date of 20170405 discloses a slag sampling device for use in a TBM excavation process, which belongs to the technical field of slag sampling and provides a slag sampling device for use in a TBM excavation process, which can greatly reduce the difficulty and risk of sampling while ensuring good representativeness of slag sampling. The device comprises a slag discharge mechanism arranged in the TBM, the slag discharge mechanism comprises an upstream slag conveyor belt conveyor, a downstream slag conveyor belt conveyor and a transfer trolley, an upper funnel and a lower funnel are arranged on the transfer trolley; the device also comprises a sampling belt conveyor and a sampling slag hopper, the sampling belt conveyor is reciprocally mounted on the transfer trolley as a whole, and a slag inlet end of the sampling belt conveyor can be moved between the upper funnel and the lower funnel to convey the slag discharged from the upper funnel into the sampling slag hopper. The utility model realizes the purpose of directly sampling by the sampling belt conveyor, which ensures that the sampled slag body has strong representativeness on the one hand, and makes the sampling process very convenient and safe on the other hand.

[0004] Although the sampling device can sample the slag during the excavation process by means of a conveyor belt, during the application process, the slag to be sampled will fall directly from the upper funnel onto the sampling belt machine. In this process, the slag falling on the sampling belt machine will not only damage the sampling belt machine, causing damage to the sampling belt, but may even cause part of the slag to splash out of the sampling belt machine, affecting the surrounding construction personnel, posing certain safety hazards. For this reason, we have proposed a slag sampling device for use in the TBM excavation process. Summary of the invention
