This invention relates to the field of lightning arrester manufacturing technology, specifically to a mold needle for anti-discharge electrode coating, a mold, a mold manufacturing method, and a lightning arrester production method. The mold needle includes a needle rod for forming a discharge gap during lightning arrester production; symmetrical flexible abutment surfaces are provided on both sides of one end of the needle rod. Each flexible abutment surface includes a mounting surface located on the side of the needle rod end and a flexible pad fixed to the mounting surface; the flexible pad includes a concave spherical abutment portion and an extension portion located above the spherical abutment portion; the extension portion is higher than the horizontal plane where the center of the spherical discharge electrode is located; when multiple needle rods are spaced apart, the flexible abutment surfaces on opposite sides of adjacent needle rods are adapted to abut against the spherical surfaces on both sides of the same spherical discharge electrode. By flexibly sealing the spherical surface of the spherical discharge electrode with the flexible abutment surface, the hard contact of the existing mold needle is replaced with a flexible sealing abutment, which solves the problem of silicone rubber coating on the spherical discharge electrode during the vulcanization and composite jacketing of existing mold needles.

This invention belongs to the field of concrete pavement paving technology, specifically referring to a paving device for cement concrete pavement in highway construction. It includes a paving machine, a material distribution box fixedly connected to one side of the paving machine, side material distribution rollers rotatably connected to the inner walls of both sides of the material distribution box, and swing blades movably connected in a circular array on the side material distribution rollers. Main material distribution rollers are fixedly connected coaxially to the side material distribution rollers on both sides. A turning guide rail is fixedly connected in a linear array to the inner wall of the material distribution box. This invention breaks up internal lumps in the concrete while simultaneously shoveling and scattering the bottom layer of concrete. It also drives the swing blades to rotate and push materials. When encountering unbroken lumps or large stones, impurities are discharged, preventing them from mixing into the paving layer and causing defects such as hollow areas and cracks in the pavement. The side material distribution rollers rotate synchronously with the rotating disc, achieving reciprocating compaction of the concrete pavement edges. After compaction and resetting, the upper concrete is extracted to fill the edge gaps.

This invention relates to the field of bitter orange (Citrus aurantium) fermentation management technology, and particularly to a bitter orange fermentation quality detection system and method based on colony characteristic analysis. This invention combines the shape characteristic data and colony distribution data of bitter orange to analyze the distribution characteristics of colonies during the fermentation process; thereby analyzing abnormal colony distribution at the folds of the bitter orange; combining the origin information data and colony distribution data of the bitter orange, it analyzes the impact of microbial community differences on the fermentation process, and further analyzes the interference of the bitter orange's origin on the fermentation process; based on the analysis results of abnormal colony distribution at the folds of the bitter orange and the analysis results of the interference of the bitter orange's origin on the fermentation process, the fermentation quality of the current batch of bitter orange is evaluated; this achieves precise screening of bitter orange, ensures the homogeneity and stability of the fermentation process, and reduces the risk of fermentation process runaway.

This invention discloses a pipeline conveying device for foamed concrete, relating to the field of concrete conveying. It includes a concrete conveying pump, a vibrating frame, a combined pipeline, and a pipeline placement rack. An inclined pipeline is installed on the vibrating frame, with its bottom end connected to a return pipeline. The inlet of the concrete conveying pump is connected to a flange pipeline, which in turn is connected to the outlet pipeline of a concrete mixer via a first valve. The return pipeline includes a first pipeline, a second pipeline, and a valve. The two ends of the first pipeline are connected to the first port of the valve and the outlet of the concrete conveying pump, respectively. The two ends of the second pipeline are connected to the second port of the valve and a first flexible hose, respectively. The two ends of the first return pipeline are connected to the second pipeline and the flange pipeline, respectively. The two ends of the second return pipeline are connected to the first pipeline and the outlet pipeline, respectively. The two ends of the combined pipeline are connected to the high end of the inclined pipeline and the pipeline placement rack, effectively preventing the problem of reduced pipeline cross-sectional area caused by the accumulation of solidified layers.
