The utility model discloses a brown rice processing device based on a flexible hulling technology, which relates to the technical field of brown rice processing and comprises a machine shell, the upper end of the machine shell is connected with a feeding hopper, a material distributing mechanism located below the feeding hopper is arranged in the machine shell, a hulling mechanism located below the material distributing mechanism is arranged in the machine shell, and the hulling mechanism is located below the material distributing mechanism. A shell removing mechanism is arranged in the machine shell, a screening mechanism located below the shell removing mechanism is arranged in the machine shell, a movable groove is formed in the side wall of the machine shell, the screening mechanism is located on the inner side of the movable groove, a blowing fan is installed on one side wall of the machine shell, and an impurity outlet pipe is connected to the other side wall of the machine shell. According to the utility model, uniform intermittent blanking of rice can be realized, one-time excessive blanking of rice can be avoided, the stability of subsequent rice hulling and screening processes is further ensured, meanwhile, flexible hulling is utilized, mechanical damage of traditional machinery to brown rice can be avoided, the broken rice rate is reduced, broken rice can be screened out, and the quality of discharged brown rice is ensured.

The invention provides a coal and rock mass hydraulic grooving-fracturing pressure relief-gas permeability increasing treatment device and method.The coal and rock mass hydraulic grooving-fracturing pressure relief-gas permeability increasing treatment device comprises a hydraulic grooving module, a hydraulic fracturing module and a connecting piece, and the hydraulic grooving module comprises a jet device and a first conveying pipeline; the first end of the first conveying pipeline is connected with the jet device, the second end of the first conveying pipeline is connected with a cutting fluid source, and the jet device jets a target hole section of a target drill hole; the hydraulic fracturing module comprises a first packer, a constant-pressure opener and a second packer, the first packer and the second packer plug a target hole section of a target drill hole to form a fracturing cavity, and the constant-pressure opener is used for allowing fracturing fluid to flow to the fracturing cavity after the target drill hole is plugged; the connecting piece is arranged between the jet device and the first packer and used for connecting the hydraulic grooving module and the hydraulic fracturing module together. In this way, the problem that in the prior art, the working efficiency of roof pressure relief and gas drainage is low is solved.
