description

The invention relates to a beet harvesting machine with an in-phase working one provided on one side of the machine Heading device and driven longitudinal beet cleaner in front of the Lifting tool.

Such beet harvesting machines have already become known several times in practice. You still have the disadvantage a construction-intensive / cumbersome structure.

The invention is therefore based on the object of providing a few complex beet harvesting machine of the beginning To create mentioned type, which is equipped with a simple drive of defoliation and longitudinal cleaner rotor is.

According to the invention, this is achieved in that the rotor axes a defoliation rotor and the beet longitudinal cleaner arranged directly in front of the lifting tool (lifting coulter) run in parallel and are coupled in terms of drive, preferably driven by a common transmission.

Such a beet harvester is characterized by a simple drive for the defoliation and cleaning rotor. Due to the parallel to each other and transverse to the machine direction of travel running rotor shafts is guaranteed, that the defoliation rotor and also the cleaning rotor only have an acceleration pulse acting in the row alignment exercise and thereby a side throw from lGse and out Beet standing high on the ground is excluded, which ultimately significantly reduces lifting losses.

The defoliation rotor acts as a flail chopper perform, and which shows a simple structure and not only defoliated, but also shredded the leaf material and spreads or accelerated for the purpose of sideways conveying.

Because of the parallel rotor shafts, they are more advantageous Simple wraparound drives can be used. The Unischlingmittel (V-belts, chains or the like.) Can be particularly short if according to a preferred embodiment between the two rotor shafts one moved by the common gearbox with two pulleys / chain wheels (or a double-track pulley or a Doppe1 chain sprocket) equipped shaft - so-called. Main shaft - It is provided from which in the machine direction of travel seen to the front and to the rear one of the two belt drives branches off.

In a preferred embodiment, the main shaft is between two drive elements, i.e. driving pulleys / sprockets of the two belt drives, designed to be articulated, and at least that of the belt drive for the main shaft part belonging to the defoliation valve can be pivoted for tensioning the belt drive and can be fixed in the various pivoting positions. This execution allows easy tensioning of the respective looping means (Belt, chain).

In a further preferred embodiment, the main shaft is of the rotor drive stored in a frame-mounted bearing tube on which the defoliation rotor support frame pivoted in height. This has a simple structure and a compact design.

The lifting device 2 has a lifting share 21, \ i / elchem a longitudinal cleaner 22 is connected upstream. This longitudinal cleaner 22 can with its driven shaft (rotor axis) 22a in height and / or at a distance from the lifting point in the longitudinal direction of the machine be adjustable.

The defoliation rotor / pre-topper 11 and longitudinal cleaner 22 are drive-coupled and from a common main drive powered off.

Preferred configurations of the drive connection is the two examples according to FIGS. 1 and 2, which will now be described one after the other:

A power input shaft that can be connected to a power source, preferably to a power take-off shaft leading to the tractor 41 is non-rotatably connected to a belt drive 42, which has a gear 43, in particular angular gear, drives. This gear 43 is via a substantially transverse to the machine longitudinal direction / direction of travel F running Articulated shaft 44 connected to a main shaft 45, which extends between the pre-topping shaft 11a and the longitudinal cleaning shaft 22a extends and is each coupled to the same via a belt drive 46/47. the Belt drives 46, 47 extend on one side
