The invention provides a vertical belt middle sampling head, which comprises a frame structure, a sampling bucket structure and a multiple supporting rollers supporting construction; the sampling head frame is formed into door frame type structure; the sampling bucket is connected to the connection plate on the transmission shaft by a bolt; the transmission shaft is suspended in the middle position on the inner side of the frame by an integrated vertical bearing seat; multiple supporting rollers support is adopted on both sides of the sampling bucket; the belt on the sampling position is shaped more approaching to arc; a discharging opening is disposed on outer side of the supporting rollers. The sampling buckets rotates around the shaft to obtain the materials from the whole section, and dumps to the discharging opening; and completes one sampling period once rotating one cycle. The invention adopts vertical door frame structure, has a flexible mounting position, can be mounted in the whole working intermediate section of the belt conveyor, is not influenced by the central rack of the belt support, is suitable for large-width belt; and the belt is shaped more approaching to arc accordance with the sampling bucket movement track, thus the sampling bucket sampling section is more perfect to has no surplus material.
