The invention relates to the field of agricultural mechanical engineering, in particular to root crop cleaners from the remains of tops used in beet harvesting machines.

The purpose of the invention is to improve the quality of cleaning heads of root crops from tops.

Figure 1 schematically shows a cleaner heads of root crops from tops on the vine, top view; figure 2 - section aa in figure 1; in Fig. 3 - section BB in Fig.2.

The root crop cleaner from the tops contains a vertical shaft 1 fixed in the bearing supports 2. A pulley 3 of the shaft drive is set in motion at the upper end of the shaft 1, and a disk 4 is fixed at the lower end. On the lower plane of the disk 4, flexible cleaning elements are fixed in pairs on the bearing 4 made in the form of coil springs. One of the springs 6 is made cylindrical, and the shape of the coils of the other spring 7 is made varying from a circle at the attachment point to an eccentric figure with the eccentricity C constantly increasing in the direction from the disk 4. The springs 6 and 7 are mounted in the bearings 5 on the axis 8 , on the upper end of which drive sprockets are installed 9. The sprockets 9 are connected by a kinematic chain 10 with a drive sprocket 11 mounted on the shaft 1. The chain 10 is mounted on the sprockets 9 in such a way as to provide the opposite direction of rotation of the springs 6 and 7 relative to the disk 4. The tension of the chain 10 and a reliable angle of sprocket 9 are provided by the intermediate sprockets 12, the springs 6 and 7 are installed in the supports 5 so that the distance between the axes of rotation is C 2r + I. where r is the radius a cylindrical spring and the radius of the eccentric spring in the place of its attachment to the disk 4, and I is the maximum value of the eccentricity of the spring with the eccentric shape of the coils.

The head cleaner of root vegetables from the tops of the vine works as follows.

When the cleaner moves along the rows of beets, the movement from the drive system is transmitted to the pulley 3 of the vertical shaft 1. rotating it around its axis in the bearing

the bearings 2. Together with the shaft 1, the disk 4 rotates with the springs b and 7 fixed on it. At the same time, movement from the drive sprocket 11 by the chain 10 is transmitted to the sprocket 9 of the springs 6 and 7. The springs 6 and 7,

rotating with the disk 4 and relative to the disk 4 and one another, they repeatedly act on the tops of the tops, copying the heads of root crops, and remove it, cleaning the roots from the tops of the tops. When rotating the springs 6

and 7 relative to each other in their lower part, the distance between the springs changes from maximum to zero. In this case, the long petioles of the tops, caught in the gap between the pair springs, pinch

between the turns of adjacent springs and are separated from the heads of root crops, increasing the efficiency of their cleaning.

Claims (1)

The claims The root head cleaner from tops on the root, containing a drive disk fixed on a vertical shaft, carrying flexible cleaning cantilevers mounted on its lower plane elements made in the form of coil springs, characterized in that. that, in order to improve the quality of cleaning heads of root crops, coil springs are fixed in pairs with the possibility of rotation relative to the disc towards each other, one of each pair of springs being cylindrical, and the shape of the coils of the other made varying from a circle at the mounting location on the disc to an eccentric figure with the eccentricity constantly increasing from the disk, while the distance between the axes of rotation of the pair springs is equal to C 2r + I, where r is the radius of the coils of the coil spring, and I is the maximum value eccentricity springs with eccentric coil shape.
