Description

Device for cleaning the walls of cereal cells and other silos

The invention also provides for cleaning the walls of cells of round and other round and multi-angular cross-sectional forces from impurities and residues of stored material.

U doposia! of known cell wall cleaning devices, constructed on a mechanical principle, the pressure of the working member on the cell wall is due to the weight of the device or the pressure springs, which does not ensure the required quality of work. In addition, the rotary brush arm assemblies require the presence of a human in this space when the device is installed in the cell.

The above-mentioned drawbacks are eliminated by a cleaning device according to the invention, wherein the dirt from the walls is wiped off by a set of rotating cables with a weight unwound by centrifugal force from the cleaning wheel driven by an electric motor. The electric motor with the cleaning disc forms one unit suspended in the middle of the cell on the steel wire ropes. Tilting arms secure the electric motor against rotation. When the electric current is switched off, the cables are wound up by a coil spring, which together with the tilting arms allows easy manipulation of moving the device from one cell to another.

The cleaning cables require a greater pressing force, thereby achieving a more efficient cleaning of the cell walls. Larger impurities are removed progressively due to the considerable flexibility of the ends of the cleaning wires. Said elasticity * allows cleaning of the cells and the multi-wavelength cross-section, where the ends of the strands in the narrowest cross-section of the cell most bend and gradually align the cells to the same, thereby cleaning the entire sheath while starting the whole device.

The accompanying drawings show the overall assembly of the cleaning apparatus, where in FIG. 1 is in the transport position, FIG. 2 and slid on ·! · end! and in FIG. 3 yeah in the prone position. In FIG. 4 shows a sectional view of a roll in partial cross-sectional views, both in front view and in pddoryea.

The mobile winch 1 (Fig. 3) is positioned above the opening of the cell and the extension of the supports 2 stabilizes the device. After removal of the grid at the step opening e into the cell, the cleaning device will lower so that it is possible to insert and swivel the boom guide extensions 3. The assembled device and the elongation under the cell ceiling and the auxiliary rope · e fold the wounded wound. The maximum tilting of the rails is limited by the stops with the spring 4 on the wired steel ropes 5. After this action e, the device lifts to the highest position and detaches the auxiliary rope from the cross 5. Thereafter, the entire device is lowered successively to the bottom of the unwound ropes from the drum 10 coupled to the intermediate electric cable 12, and the entire sheath of the cell is screened. By spinning the cleaning disc of the ball 28 (FIG. 4), the centrifugation of the winding cables 29 located inside the cleaning disc in several rows along the aaba is induced by centrifugation. The end of the picking ropes is attached to one side of the inner drum 25, which is connected to the transmission pin of the electric motor 24 by a tongue 21 and a screw 22. The other side is adapted to accommodate the inner end of the spiral spring 31. roll. The cleansing wire space encloses the outer shield 27 and the spiral spring space the inner shield 32. The maximum unwinding is given by the length of the cables and defines the balls 28 in a wound manner. The groove on one of the outer drum edges is for the outer conona.
