Description

The invention relates to agricultural machinery, particularly to devices for cleaning root crops from haulm residues ispblzuemym in machines for trimming the tops and harvesting of root crops, such as sugar beet, separate spo- ⁵ sobom.

The purpose of the invention is improving the quality of cleaning root crops from tops and eliminating them, damage.

The drawing shows a cleaner of the root root wok from tops on the vine, general view.

The cleaner includes a drum made in the form of two disks 3 fixed on the horizontal shaft 1 by means of the hubs 2, one of which is at least 15 mounted freely along its axis and is spring-loaded with a spring 4 relative to the shaft in the same direction. The disks 3 carry segments of chains 5 located along the generators of the drum. Moreover, the drum is equipped with an elastic rope 6, threaded around the circumference of the drum to all the links of the segments of the chains 5 and attached at its ends to its disks with the help of clamps 7 and clamping bolts 8.

Cleaner heads of root crops from tops 25 on the vine works as follows.

With the translational movement of the unit, the drive cleaning drum rolls with sliding along the field surface. The hinged suspension of the drum ensures copying of the roots of root crops by the height of their position relative to the soil surface level. When hitting the root head, the working surface bends somewhat at the point of contact with it, moving disks towards each other, compressing the spring on the shaft. Due to the fact that the rope 6 orientates each link of the segments of the chains 5 in contact with the surface being treated, the chain web completely removes the remains of the tops from the heads of root crops. The contact of each link with the treated surface is provided for any deflection of the chain web in the form of the surface of the head. The presence of the rope 6 eliminates damage to the heads, since when the working surface of the drum meets the surface to be treated, the links of the segments of the chains 5 are able to freely move in directions along its axis, which prevents jamming. When rolling the drum from the heads, the chain web returns to its original position.

The invention relates to agricultural machinery, in particular to devices for cleaning root crops from residues of leafy tops, used in machines for cutting leaves and harvesting root crops, for example sugar beet, in a separate way. The purpose of the invention is to improve the quality of cleaning of root crops from tops and eliminate their damage. The drawing shows the cleaner heads of root crops from the foliage on the vine, a general view. The cleaner includes a drum, made in the form of two disks 3 fixed on a horizontal shaft 1 by means of the hubs 2, one of which is at least freely mounted along its axis and is spring-loaded with spring 4 relative to the shaft in the same direction. The disks 3 carry the lengths of the chains 5 located along the drum-forming ones. Moreover, the drum is equipped with an elastic rope 6, threaded around the circumference of the drum in all links of the segments of the chains 5 and attached to its ends with the help of clamps 7 and clamping bolts 8. The cleaner heads of root crops from the tops on the root works as follows. As the machine moves forward, the drive cleaning drum rolls and slides over the floor. The drum hinge provides for copying the heads of root crops according to their height relative to the level of the soil surface. When driving over heads: a root crop, the working surface bends slightly at the point of contact with it, moving towards each other the disks, compressing the spring on the shaft. Due to the fact that the rope 6 orients each link of the segments of chains 5 on contact with the treated surface, the chain web completely removes the remains of the tops from the roots of the root crops. The contact of each link with the treated surface is ensured at any deflection of the chain blade in the shape of the surface of the head. The presence of the rope 6 eliminates damage to the heads, since upon meeting the working surface of the drum with the surface to be processed, the links of the segments of the chains 5 are able to move freely in the directions along its axis, thus preventing jamming. When the drum rolls off the heads, the chain web returns to its original position. Claims of the head root crop root cleaner, including a drum made in the form of a horizontal shaft with disks fixed on it, at least one of which is mounted on the tube freely in the direction along its axis and spring-loaded relative to the shaft in the same direction, and the disks are connected by chain segments placed along the drum-forming structure, characterized in that, in order to improve the cleaning quality of root crops. The tops and the elimination of their damage are not, it is equipped with a flexible elastic rope fixed with its ends on the disks, located around the circumference of the drum and threaded through all the links by a segment of chains.
