DEVICE FOR DRY CLEANING OF ROOT AND TUBER CROPS Russian patent published in 2024 - IPC A01D33/08 F26B11/04 

FIELD: agricultural engineering.

SUBSTANCE: device contains a chamber in which there is a pipeline with uniformly installed vertically directed nozzles, a fan, a heating element, a motor, a water filter, on the side surface of which a drain is installed at the bottom. The chamber is made in the form of a horizontally located cylinder on one side with a rigidly fixed bottom, the side walls of which are perforated and elastic bushings with beads at their ends are installed in the perforation holes. The outer diameter of the cylindrical part of the sleeve is equal to the inner diameter of the perforation holes. The beads located inside the chamber have fingers on the upper surface that are uniformly made along their entire plane and are equal in height to each other. The surface area of the beads is larger than the surface of the beads located outside the chamber, which is located inside the casing, made in the form of a truncated cone. The central axes of the chamber and casing coincide. On the smaller base of the casing, a motor is installed in its centre, the shaft of which is rigidly fixed centrally at the bottom of the chamber. On the larger casing base there are two doors, between which there is a strip of the larger casing base. The lower door is made in the form of a segment of the circle of the larger casing base with a height up to the lower edge of the chamber wall, and the upper door has a height from the strip of the larger casing base and no more than half the diameter of the circle of the larger casing base. The doors are sealed. On the side surface of the smaller base of the casing, an exhaust pipeline is installed in the upper part, at the end of which an upper disk is installed through a bearing, the diameter of which is equal to the diameter of the lower disk and they are mutually parallel, and between which four shaped plates are rigidly fixed, the side surfaces of which are interconnected and made in the form of a sector of the circle of the disk passing into the concave part of the sector of the circle of radius R1 with the sector of the circle of the exhaust pipeline and with the convex part of the sector of the circle of radius R2 with the formation of four channels equal in both width and length. An exhaust pipeline with disks is installed inside a water filter with an acute angle of inclination of its bottom relative to the horizontal. An outlet pipeline with a duct-type exhaust fan is installed on the upper surface of the water filter.

EFFECT: increase in the storage time of root tuber crops with high reliability of the working elements, low labour intensity of cleaning the casing and water filter, as well as simplicity of design.
