Description

In existing structures of combine harvesters for harvesting root and tuber crops, in order to remove dug roots or tubers from the ground, chain bar conveyors are used, along which roots or tubers lose part of the ground falling through the holes between the bars. However, on such a conveyor only a part of the ground is separated, and the roots are collected in the bunker not sufficiently cleared of soil and leaves, especially when harvesting in moist soil, which leads to the need for additional manual cleaning of the roots. It is proposed to install a freely rotating string of drum over the rod conveyor, which can also move in height guides, and for cleaning the roots from the leaves, a fixed divider is installed under the conveyor belt and, moreover, knives are installed on a row of conveyor bars. , tearing off the remnants of the leaves when leafing the roots to the divider.

FIG. Figure 1 shows the layout of the conveyor with a drum and a divider; in fig. 2 - node divider.

The device consists (Fig. 1) of a horizontal bar conveyor 1, a bar drum 2, a divider 5 installed above it, and a conveyor 4 discharging peeled roots of a beet.

The bar drum 2 is rotated upon contact with the beetroot moving on the conveyor and can, in addition, be moved along the height B of the guides together with the axis and the spindle plates.

If necessary, the acceleration of the drum 2 can be inhibited and then it can only be moved in height.

The fixed divider 3 (Fig. 2) is made in the form of a curved plate located at the point where the conveyor moves downwards. The width of the plate slightly exceeds the width of the conveyor belt /. The distance between the edge of the divider and the conveyor bar is 10-12 mm.

and was chosen in such a way that beetroot leaves and knives 5, welded to transnorter's nuts, could pass through the gap in an amount of 3-4 pieces. the entire length of the transnorter web.

The gap b between the knife-picker 5 and the edge of the divider 3 is 3-4 mm. The rooted beet roots with cut tops of the tops fall on the bar conveyor /, which carries them together with the remains of the tops under the bar drum 2.

When the drum rolls across the roots, they are knocked off the ground and go down under the conveyor. In order to increase the effect of the drum (when the combine operates in weather conditions, and wet soil), it is also braked by the roots, running around the bottom surface of the drum, it is better cleaned from the ground.

After reaching the divider 3, the roots are somewhat delayed, acquiring a rotational movement, while the leaves and weeds are dropped from the roots onto the canvas and, passing into the gap under the edge of the divider, are led down and the centrifugal force is dropped to the ground. At the same time, due to the dampening of the roots, they are further cleaned from the ground.

The roots are cleared of uncut tops by knives 5, which break off the tops when dragging them with a moving conveyor belt when the knife crosses the tops of the tops.

Freed from impurities, the roots of the beet, a stream of subsequent roots, pressed against the edge of the divider. Due to the fact that the point of contact of the root to the edge is located below the center of gravity of the root, the latter is thrown over the edge of the divider and falls on an inclined conveyor 4

With the scrappers of this transnorter, the roots are carried away upward and fed into a special bunker or car.

Subject invention

B A device for beet harvesters for cleaning a heap of beet roots from the ground, consisting of a horizontal bar conveyor, a divider of the working mass, an inclined conveyor and knives-toppers of the tops, characterized in that, in order to improve the quality of cleaning the beet roots from the ground, above horizontal the bar drum of free rotation and with a variable height of the center of rotation is installed as part of the bar conveyor.

2. The form of the device to the window harvester according to claim 1, characterized in that, in order to improve the quality of cleaning the beet roots from leaves and other plant residues, a fixed divider is installed in it, forming a gap between the bar conveyor and the inner surface of the divider.

3. The form of making the device to the beet harvesters according to claim 1, characterized in that, in order to break the remains of the tops from the roots, on the rods of the horizontal conveyor at intervals the cutting knives are welded.
