Abstract

The invention relates to the agricultural machinery industry, in particular to the tops, and to the machines of the root-harvesting machines, the purpose of the invention is to improve the quality of trimming tops and simplify the design of the apparatus. The cutting device of the root-harvesting machine contains a shaft 2 carrying cutting elements rigidly fixed on it, made in the form of flexible plates 1, with its middle part freely placed in the grooves of the cap 3.VThe cap 3 is connected to the copy part by means of a linkage 5 with a copy mechanism shaft 2 freely in a direction along their common axis of rotation. When the apparatus of the plate 1 is operating under the influence of moving up or down, depending on the movement of the copying mechanism. the cap 3 is bent, repeating the direction of movement of the mechanism copying the heads of the root crops, and cutting them. 3 il. with

The invention relates to the se: the economic - mattress, in particular, the root-harvesting machines of the root-harvesting machine used in the harvesting of beets.

The purpose of the invention is to improve the quality of pruning tops and simplify the design of the apparatus.

FIG. 1 shows a schematic side view of a root-harvesting machine; in fig. 2 is a section A-A in FIG. one; FIG. 3 is a sectional view of FIG. one .

The root-harvesting apparatus of the root harvesting plant contains flexible plates 1 rigidly attached to the lower part of the drive shaft 2. Kol-Pak 3, which has a movable connection along the axis of the drive shaft by means of bearings A, is connected with a copy mechanism (not shown) through bearings A,

The drive shaft 2 in the axial direction is stationary and has a support on the frame 6 of the apparatus. The movable parts of the haul-off apparatus are flexible knives 1, the cap 3 is connected by bearing 4 to the suspension linkage system 3, by means of which they have a hinge support on the frame and are kinematically connected with the copying mechanism of the heads of the root crops. The torque from the drive shaft 2 is transmitted to the flexible plates (knives) 1, which are installed in the slots 7 of the bottom 8 of the cap and transmit the rotation of the cap 3,

The root harvesting machine works as follows.

Through the copying mechanism of the root crops, the force through the lever system of the suspension 5 is transmitted by means of the bearing 4 to the cap 3} which moves in the axial direction, respectively. With the help of 1-5 guide grooves 7, the cap 3 acts on the cutting plates 1, which allow copying, which ensures accurate copying of the heads of the root crops and trimming of the tops.
