Abstract

The invention relates to devices used in rooting machines. The aim of the invention is to increase its operational capabilities. Blade beater of the Korneoborochnaya machine contains a drive shaft 1 on which hinges 3 are fixed, in which blades 2 are mounted. On the drive shaft 1 there is also an annular hollow cylinder 5 larger than the shaft of diameter and contains on the outer and inner surfaces through arcuate grooves 8, into which the blades 2 extend. In so doing, compression springs 9 are installed inside the hollow cylinder 5, which provide the blades with springing relative to the shaft 1. The arcuate grooves 8 on the outer surface of the hollow cylinder 5 are closed arcuate plates 10, mounted on each blade 2. 1 il.

The invention relates to agricultural machinery, in particular to devices used in the harvesting of beets.

The purpose of the device is to increase its operational capabilities.

The drawing shows the structural diagram of the blade beater root-harvesting machine.

Blade beater rooting machine consists of a drive shaft 1, on which the blades 2 (with lining on the ends) are mounted with the help of hinges 3, mounted on the shaft 1 by means of bolts 4. The shaft 1 is fitted with an annular hollow cylinder 5 larger than shaft 1 of diameter, which is fixed to it with the help of brackets 6 and bolts 7. The hollow cylinder has three through arcuate grooves 8, made on its external and internal surfaces. The blades 2 are led into the grooves 8. In the inner cavity of the annular cylinder 5, compression springs 9 are installed (stacked), each of which is located between two blades 2. On each blade 2, arcuate plates 10 fixed by bolts 11 are fixed.

Bladed beater rooting machine works as follows.

The drive shaft 1, together with the blades 2, rotates in the direction from. The beet roots clamped between the edges of the digging discs (or root grooves) are fed to the area of the rotating blades 2, and they are hit by the plates attached to the ends of the blades 2. Since the blades 2 are fixed with their ends in the hinges 3 (t. e. made rotary) and spring-loaded relative to the annular hollow cylinder 5 with the help of springs 9, the beet roots are not struck hard, but elastic. At the same time, the blades 2 can rotate in the hinges 3 by an angle provided by the dimensions of the arcuate grooves 8, which they pass. The annular hollow cylinder 5 must have a crush from its front so that springs 9 can be laid into its internal cavity. squeeze; On the body of each blade 2, arcuate plates 10 fixed by bolts 11 are fastened. Plates 10 close through arcuate grooves 8 located on the outer part of the hollow cylinder 3. The hollow cylinder 5 is larger than the shaft -1 of diameter to create a spring-loaded moment and to eliminate vegetation residues being wound on it. During operation, the ends of the arcuate plates 10 move as it were on both sides of the outer surface of the hollow cylinder 5, clearing it of adhering soil and plant residues. Taking into account the amplitudes of oscillatory movements of the blades 2 relative to the shaft 1, the arcuate plates 10 are mounted and fixed with the help of bolts 11 at the required distance from the cylinder 5.

Thus, the proposed blade beater of the root-harvesting machine is rather simple in design and more reliable in operation. In this case, only three compression springs 9 are used, devices for fastening them are excluded, there is no need to make complicated adjustments. The presence of a larger than the shaft 1, the annular hollow cylinder 5 eliminates the winding of plant residues, thereby reducing the time for its cleaning and maintenance. Beet roots and abrasive material are not in contact with springs 9 during operation of the beater, as they are closed by arcuate lO, I plates

Sizes through arcuate

the grooves 8 and the stiffness of the springs 9 should take into account the size of the harvested beet root crops and ensure the required quality of their harvest. The width of the grooves 8 should be somewhat larger than the width of the blades 2 to eliminate friction between them and possible seizure. With a strong clamping of root crops, when the rigidity of the springs 9 (Can be overcome, the blades 2 abut the edge of the arcuate grooves B, which is equivalent to the rigid connection of the blades 2 and the shaft 1. When the load is removed due to the two-sided springing of the blades 2, the latter are much faster in their original position .
