Description

Beet harvester Technical Field The invention relates to a sugar beet harvester, preferably for sugar beet, with a frame, a cleaning device, a silo for temporarily storing the dredged beet, and a lift arranged at least partially laterally beside the silo, which lift is provided for transferring the beet into the silo during a dredging operation, and with a lift rack and a conveying element which is circulated during the dredging operation. Background Such beet harvesters, which are also referred to as beet diggers, have an annular elevator by means of which the beet discharged at the end of the cleaning device is transported upwards into the bin. With reference to an axis extending transversely to the longitudinal centre axis of the beet harvester, the annular lifts (seen in the direction of travel) are located on both sides of the silo, i.e. on the left and right of the silo in a plane transverse to the direction of travel. In other respects, therefore, bins designed for the maximum permissible road width of the beet harvester are narrowed in the region of the annular elevator, so that the elevator can be fixed at the frame within the permissible vehicle width. Due to the shrinkage, the volume of the silo is reduced and this form of construction additionally causes an obstacle to the discharge of the silo. Disclosure of Invention The object of the present invention is to avoid the above drawbacks. This object is achieved by the subject matter according to claim 1. Advantageous embodiments of the invention emerge from the dependent claims and the following description. According to the invention, the hoisting machine is movably connected to the frame such that it can be transferred from a transport state to an operating state in which the hoisting machine protrudes laterally with respect to the transport state. The operating state corresponds to a state during a digging operation in which the sugar beets are dug out of the soil, cleaned and transported into the bins for temporary storage, irrespective of whether the bin walls are turned out or not, whether the transport conveyor is extended or not, the sugar beet harvester having an increased width of the sugar beet harvester (seen in the machine longitudinal direction). The width of the bin and the elevator in the digging operation, i.e. the harvesting operation, is greater than its width during the transport state, in which the beet harvester, i.e. the beet digger, can travel on the road. The width of the beet harvester in the digging operation exceeds the maximum width allowed by the road running, for example 3 meters specified in germany. In the operating state, the storage bin and the lifting machine thus have a greater installation space for their functions of beet storage on the one hand and beet transport on the other hand. The available space of the hoisting machine in the transport state limits its transport capacity in particular, but this is not critical, since during road travel no beet has to be transported from the cleaning device into the silo. According to the invention, the movement of the lifting machine in the transverse direction does not refer to the movement of the conveying elements required for operation for transporting sugar beets. Instead, the hoisting machine itself can be moved with its hoisting machine frame in the transverse direction. The transverse direction is the direction transverse to the longitudinal central axis as seen in top view. In straight running, the transverse direction corresponds to a direction transverse to the running direction, also seen in plan view. The at least one conveying element is in particular designed as a conveyor belt, preferably in the form of a screen belt. The hoisting machine has in particular two conveyor belts, preferably both in the form of screen belts. The one or more conveying elements of the hoisting machine are held, tensioned and deflected by means of load-bearing and/or deflection members, which are oriented at least approximately, preferably completely, parallel to the longitudinal direction of the vehicle. The longitudinal direction of the vehicle is based on a straight travel of the vehicle, in which the vehicle travels not with a so-called crab travel, but with successive tires and/or chains. Correspondingly, being arranged laterally sideways of the vehicle means that the hoisting machine limits the silo, in particular on one side, perpendicularly to the longitudinal centre axis extending through the silo in a top view. Correspondingly, the hoisting machine will extend further outwards in the operating state. The hoisting machine in particular protrudes beyond any adjacent side wall of the silo, seen in the longitudinal direction of the vehicle. As previously described, the transportation state refers to a state in which the beet harvester travels on a public road and does not exceed an allowable road width. In particular, the outer part of the elevator frame, which is furthes
