Problems solved by technology

Thus, at the same time, the maneuverability of the system to be controlled along the contour of the harvest field is affected, since the execution of the entire excavation process may be particularly in the area close to each edge area of ​​the harvest field due to the protrusion of the machine parts are affected and there may be a loss of harvest due to this

Embodiment Construction

[0046] in such as Figure 1 to Figure 3 In the schematic diagram of , a machine for harvesting root crops, in particular in the form of a fully automatic potato harvester 1 , is shown in the form of a corresponding schematic diagram. From such as figure 1 As can be seen in the side view of , the structure has the excavating device 2 in the use position while using known components. Corresponding to the excavation width B, transversely to the direction of travel F, rows of harvest R containing mixed material from the cultivated field A are accommodated on the harvest field E.

[0047] In a self-propelled fully automatic potato harvester known from ( / ; 4), the two rows R are received by means of the digging device 2, and the harvested and mixed materials are loosened from the digging device The mixture G is then displaced by the first longitudinal conveyor belt 3 in the conveying direction FG counter to the direction of travel F. During this conveying phase, the conduction ta...

Abstract

A machine for harvesting root crop has a lifting device that in a position of use on a harvest field lifts several rows of the crop with admixtures from the soil transversely to the travel direction in accordance with a lifting width. From the lifting device the loosened mixture of crop and admixtures is movable opposite to the travel direction by a first longitudinal conveyor and is transferred onto a second screening belt conveyor. Between longitudinal conveyor and screening belt conveyor, a transfer zone is defined with belt overlap. The first longitudinal conveyor in the conveying direction together with the upstream lifting device forms a module that is movable in transverse direction of the machine relative to the second screening belt conveyor. This module, relative to the common transfer zone, can be moved at least sectionwise into a position of lateral spacing relative to the second screening belt conveyor.

Description

technical field [0001] The invention relates to a machine for harvesting root crops, in particular in the form of a fully automatic potato harvester according to the preamble of claim 1 . Background technique [0002] Machines for harvesting and processing root crops, especially potatoes, have been known for a long time, especially in different embodiments as trailed units or self-propelled machines. In this type of machine design, use is made of excavating devices which receive multiple rows of harvest containing field debris at a time, together with subsequent conveying and cleaning systems. Such a design with a root crop harvester towed by a tractor is described in DE3235087C2 ( / ; 1). [0003] In the fully automatic potato harvester according to DE93205759U1 ( / ; 2), also based on a receiving device provided with a group of excavators, a subsequent screening conveyor belt is provided, by means of which the harvest and impurities are screened The conveyor belt is led to t...
