Abstract

The invention allows to improve the quality of cleaning heads of root crops and to increase the reliability of the cleaner. The root golovfs cleaner from the tops of the roots on the root contains a drive mechanism, as well as a horizontal disk, which is rotatably mounted on the shaft. Cleaning elements and a telescopic rod are placed on the bottom of the disk. The telescopic rod is located in the center of the disk eaxially with the shaft on which the disk is mounted. A small diameter disk is attached to the lower part of the rod with spokes radially hingedly fixed around the periphery of the disk. A corrugated elastic tube is placed around the telescopic rod. The ends of this tube hermetically cover the upper and lower parts of the telescopic rod. The cleaning elements are made up of components: the middle part consists of segments of chains, 6 the upper and lower ends are spiral springs, the upper ends of the springs are attached to the upper disk, the lower ends are attached to the ends of the spokes of the lower disk / A spiral spring is put on the spokes to increase the guarantee of cleaning heads of root crops from the remains of tops. 2 s.p. f-ly, 3 ill.

Description

FIELD OF THE INVENTION This invention relates to root crop heads for removing root leaves and can be used as a unit in machines for harvesting root crops, for example, sugar beets.

The aim of the invention is to improve the quality of cleaning heads of root crops and increase the reliability of the cleaner.

Fig. 1 shows a kinematic diagram of a cleaner with a drive mechanism, Fig. 2 shows a cleaner with fasteners of cleaning elements, general view; see. From the same, bottom view.

The root head cleaner from the tops of root leaves contains a drive mechanism made in the form of a system of vertical shafts 1, 2, mounted in bearing bearings 3 and articulated to transmit counter-directional rotation by a cylindrical gear 4, The lower ends of the shafts 1,2 are equipped with sprockets 5, 6 and chains 7, 8, which are connected with sprockets 9,10 of vertical shafts 11,12 also fixed in bearing bearings 13, 12, 15, 16. At the ends of vertical shafts 11, 12 disks 17, 18 are mounted with mounted on their working

the surfaces with telescopic rods 19, 20, coaxial with the shafts 11, 12. At the lower ends of the telescopic rods are fixed discs 21, 22 of small diameter with spokes pivotally fixed around the periphery 23. The sliding part of the telescopic rods 19, 20 is protected by corrugated elastic tubes 24, 25 Radially placed between the upper disks 17,18 and the lower small diameter disks 21, 22, the cleaning elements 26 are made integral. Their middle part consists of segments of chains (indicated in the drawing a), and the upper and lower ends of b are coil springs, hooks 27 fixed. In the holes on the periphery of the upper disk 17 and 18 and the spokes 23 of the lower disk 21, 22. On knitting needles 23 put on coil springs 28.

The number of pairs of counter-rotating discs with grids of cleaning elements is selected depending on the type of topping machines for six-row harvesters is six.

Cleaner heads of root crops from the remains of bots on the vine works as follows.

With the progressive movement of the topping unit and the contact of the first row of each pair of rotating (upper and lower) disks 17, 21 with the root head, the lower disks 21 are lifted, compressing the sliding part of the telescopic rods 19, and each cleaning element 26 pressed up takes a form that ensures the full coverage of the root head. Moreover, the presence of 26 segments (a) of chains in the composite cleaning elements during rotation makes it possible to bring down the tops due to the mass energy of these segments. The contact area with the surface being cleaned is also increased due to the spiral springs 28 on the spokes 23 of the lower disk 21. The hinged fastening of the spokes 23 to the lower disk 21 also helps to improve the contact of the surface being cleaned with the Cleaning elements and at the same time increases the reliability of the device

due to the ability to move the spokes 23 up and down during the cleaning process. In addition, sequential processing with rotationally opposed rows of discs with

cleaning elements 26 improves the quality of cleaning. So, if the first row of discs with cleaning elements only weakens the connection between the tops and the head of the root crop, then the second row of discs will already produce

complete separation of tops from root crops.

Thus, the proposed root crop cleaner from the leaves of the tops of the root gives a positive effect, consisting in improving the quality of cleaning root crops, as well as a significant increase in the reliability of the entire structure.
