The invention provides a seed-production corn male parent cutting and laying machine. The seed-production corn male parent cutting and laying machine comprises a rack, a cutting mechanism, a clamping and conveying mechanism and a crop lifting rod, wherein the cutting mechanism is arranged at the bottom of the rack and is used for cutting seed-production corn male parent plants; the clamping and conveying mechanism further comprises a chain type conveying mechanism and a compaction mechanism, wherein the chain type conveying mechanism is fixed in the middle of the rack and is used for pulling, clamping and conveying the cut seed-production corn male parent plants; the compaction mechanism is mounted on the rack, is arranged relative to the chain type conveying mechanism and is used for compacting the conveyed seed-production corn male parent plants on the chain type conveying mechanism; the crop lifting rod is mounted in the middle of the rack, is located below the chain type conveying mechanism and is used for collecting and guiding the seed-production corn male parent plants. According to the seed-production corn male parent cutting and laying machine disclosed by the invention, the cutting mechanism and the clamping and conveying mechanism are cooperated with each other so that cutting and ordered laying of the male parent plants are finished, mechanical work of cutting the male parent plants is realized, the working efficiency is improved and the production cost is reduced.

The invention relates to a multipart chain fixing device for securing at least one conveyor chain on a trough element of especially an underground scraper chain conveyor. The fixing device comprises a bridge part (60), which has a bridge bar (62) that at least partially overlaps the conveyor chain in a positive-locking manner and ends in two lateral side end portions (61). It also comprises two side parts (70), which are fastenable to the trough element pan and to which the side end portions 61are releasably securable by positive-locking means. For providing a chain fixing device, inclusive of the associated trough element and the individual components,which offer increased safety in underground usage, combined with simple assembly, the side parts (70) are releasably fastenable in a positive-locking manner in cavities in the conveyor floor of the trough element.
