Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The aim of the invention is to increase the degree of purification of root crops and reduce their damageability. The screw cleaner-conveyor contains a frame 1 on which cylindrical counter-rotating rollers 3 with spiral winding 4 are mounted in supports 2 with spiral winding 4. In the gap between the rollers there are installed flat disks 6 formed by bars of elastic material. A heap of root crops and impurities flows between the rollers and moves under the action of the spirals of the rollers and discs, while impurities are removed from the heap. 2 Il.

The invention relates to agricultural machinery, in particular to devices used for cleaning and transportation of beet roots,

The aim of the invention is to increase the degree of purification of roots and reduce their damage.

Figure 1 shows a diagram of a screw cleaner conveyor, top view; figure 2 - section aa in figure 1.

The screw cleaner conveyor of the root harvesting machine consists of 15

the main frame 1 on which in the supports

2 mounted cylindrical counter-rotating rollers 3. On rollers

3 welded spiral coils 4.

In the lower part of the rollers 3, in the middle 20 of the gap between them, on an additional frame 5, flat disks 6 are installed on horizontal axes 7, Axes 7 are perpendicular to rollers 3, and flat disks are formed by rods of elastic material 25. Each disk 6. is rigidly fixed with an asterisk 8, and disk 6 itself is mounted on axis 7 freely. Stars, daughters 8 are interconnected by a chain transfer 9, which provides rotation ^ 0 of disks 6 in the direction of winding spirals 4, i.e. in the direction of transportation of beet root crops. The discs 6 are mounted on frame 5 with mutual displacement: the neighboring discs provide ί their mutual overlap, and their outer edges are located above the horizontal axes of the rollers 3. '

Screw cleaner conveyor works as follows.

A heap of beet root crops together with soil and plant impurities is fed into the working channel of the purifier, i.e. in the space between the two rollers 3. Due to the counter-rotation of the rollers 3, the root crops fall on the outer edges of the discs 6, which do not allow nm to be clamped by the rollers 3, the discs 6, having asterisks 8 connected by a chain transmission 9, rotate and thereby rotate the beet roots around them axes of rotation and transport them in the direction of rotation. However, transportation

root crops discs 6 are intermittent, since discs 6 are mounted on frame 5 with a certain pitch. Getting into the space between discs 6, the roots are affected by rollers 3 and their spiral coils 4. Due to the fact that axes 7 are horizontal and perpendicular to the axes of rollers 3 The parallelism of the speed imparted to the roots by the disks 6 to the direction of transport is ensured, which increases the transporting ability of the cleaner. The mutual overlap of the discs 6 eliminates jamming of root crops between the rollers 3. The interaction of the beet root crops (as conical bodies) with the edges of the discs 6, and the contact with the surfaces of the wolves 3 and their windings 4 provides the beet roots with complex movement that contributes to an increase in the degree of cleaning of root crops from soil and impurities The disks 6, made of elastic material, themselves pick up and pull down particles of impurities, in addition, they clean the rollers 3 and the windings 4 from sticking with soil.

Claims (1)

Claim The screw cleaner conveyor of the root harvester, containing a frame on which a pair of rotating rotating cylindrical rollers with spiral windings are installed, installed with a gap between them and having different rotational speeds, characterized in that, in order to increase the degree of cleaning of root crops and reduce their damageability, discs are mounted between the rollers, which are located along the length of the rollers with a pitch ensuring their mutual overlap and rotation in the direction of transportation of root crops, while each This disk is formed by rods of elastic material fixed on an axis perpendicular to the vertical plane passing through the axes of the rollers, the outer edges of the disks being located above the horizontal axis of the rollers about 1595377 AAH 3
