FIELD: agricultural machinery industry. ^ SUBSTANCE: pocket-type grain cleaner comprises hollow drum with the shell made of cells of the same length, but of different standard sizes. The shells are provided with chutes and discharging screws. The drum is secured to the frame via rolling bearings that roll over the ways made at the butt between two adjacent shells. The intermediate way is twice as much in width as the remainder ways. The drive of the drum is made of friction transmission. The standard sizes of the shells gradually increases from the inlet to the outlet of the drum. The feeding hopper is mounted from the right face of the pocket-type grain cleaner from above and is provided with two conical deflecting branch pipes. ^ EFFECT: improved quality of cleaning. ^ 1 cl, 4 dwg |
