Description

Loading device for crops, in particular

tuberous root crops

Field of the invention

The invention relates to a loading device for bulbous or spherical crops such as potatoes, beets, celery and possibly also robust cabbage and pumpkin varieties.

Background of the invention

In particular, in large-scale cultivation of potatoes and turnips these are often temporarily stored in the field of arable in the form of elongated beds in the field of fruit and only then loaded onto a suitable for transport on the road vehicle. For loading these beds Verladefahrzeuge are known as such special Aufgriffsvorrichtungen whose catch organs in the field soil can be pushed under the bed and thereby gently attack the fruits. Any field soil picked up hereby or adhering to the crops may fall off at the device-side gaps and openings already in the area of the catching organs, or also in the area of the further fruiting path, e.g. a conveyor belt are formed. The removal of the field crop adhering to the crop is supported by the proper movement of the fruit as part of their displacement.

From DE 3 401 661 Al a loading device of the aforementioned type is known, which can be recognized as a hitch to a final tractors. This known loading device comprises an insertable under the fruit piles Aufgriffszunge, and over the width of Aufgriffszunge horizontally aligned conveyor belt device through which tapped across the Aufgriffszunge fruits and pulled out laterally and then passed on a sloping path and can be loaded onto a car.

CONFIRMATION COPY Object of the invention

The invention has for its object to provide a loading device for tuberous crops, especially beets or potatoes, which is characterized by a cost-effective and compact design and through which a large part of the picked up on taking the fruit farmland can be largely separated.

Inventive solution

The above object is achieved by a loading device for loading tuberous crops, with:

a slide-in bucket which has a front transverse edge area, a left side area and a right side area and can be inserted into or under a field crop heap over the front transverse edge area along a heap stripping direction,

a cross roller arrangement with transverse rollers extending between the left and right side sections and spaced from one another such that soil falling from the crops may fall down between the transverse rollers, and

a conveyor belt device which extends in a region located behind the transverse rollers,

- The conveyor belt device is integrated into the loading device such that it has a rising in the conveying direction section in a lying between the left and the right side region.

This advantageously makes it possible to guide the picked crops along an ascending path already within the insertion scoop and thus raise them above the ground level and the level of the transverse roller arrangement. Due to the gain in height within the width of the insertion blade, the lateral projection of the further conveyor belt section can be reduced or otherwise advantageous guidance of the crop outside the insertion blade can be achieved in an advantageous manner. Due to the special guidance of crops on the rising inside the slide-in conveyor belt section, as well as due to the increase of the conveyor belt section within the width of the slide-in tray, the self-cleaning of crops is supported, in addition to advantageously a large part of the crops picked Soil immediately in the area of the insertion blade drops down so that any caused by too deep engagement of the insertion blade in the soil soil recesses are almost completely closed again in the vicinity of the insertion blade by the trickling soil.

According to a particularly preferred embodiment of the invention, the insertion blade is designed such that the transverse rollers cause a lateral displacement of the picked fruit towards a preferably off-center, low-lying input area of the conveyor belt device. The transverse rollers can be designed so that they form conveyor spindles with spiral flanks, at least in sections, for the corresponding lateral displacement of the crops resting thereon. The transverse roller arrangement and the conveyor belt device are preferably arranged such that the transfer of the crops to the conveyor belt device takes place in a region offset from the center of the insertion blade to the left or to the right side region. The cross roller arrangement can be designed so that the crops run in this band input area in each case in a short path. In particular, it is possible to design the transverse roller arrangement by appropriate profiling of the transverse rollers in such a way that the crops are initially conveyed transversely away from the belt input area and only subsequently to this belt input area. The crops thus go through in the cross roller assembly a longer distance and rub against the cross rollers, and each other. As a result, the removal of soil from the crops is further supported.

The conveyor belt device is preferably designed at least in the region of the insertion blade such that it comprises a continuous belt section. Through this sieve belt section can continue to fall soil from the crops down. The sieve belt section can be formed by laterally mounted, mutually parallel rods. The enclosure and connection of the rods can be done in a conventional manner by elastic links.

The cross rollers are coupled in accordance with a particularly preferred embodiment of the invention with a drive device and can be set in rotation via this drive device. The drive device is preferably designed as an oil-hydraulic drive device and designed so that the rotational speed of the transverse rollers can be set adjustable. The transverse rollers are preferably in the left and in the right side region of the insertion blade stored. The drive of the cross rollers can also be accomplished purely by mechanical means, for example via a PTO connection. The PTO connection leads preferably first into an input gear and then, for example, to one of the transverse rollers. This driven transverse roller can then be coupled via a gear transmission, or a traction mechanism, in particular a chain drive with the other transverse rollers. This coupling is preferably carried out in a somewhat shielded region of the side cheeks, and in turn preferably via coupling heads or shaft journals protrude from the rollers bearings. The geared drive coupling of the transverse rollers with each other can be done via a gear transmission as already mentioned. This gear transmission can be designed as an open gear in which the gears are designed as largely pollution-resistant structures. It is also possible to provide geometries on the transverse rolls by which a drive coupling of the transverse rolls is achieved. The cross rollers can rotate partly in opposite directions, partly in the same direction.

The loading device according to the invention is preferably designed as a mounting device for a tractor and provided with interface devices that are too widespread connection systems, especially a front linkage of a tractor compatible. Alternatively, the device according to the invention may also form part of a corresponding Verladespezialfahrzeuges. The three-point mount can be designed, for example, on a front lifting gear according to DIN ISO 730-1.

The loading device according to the invention preferably comprises a support structure which allows a connection of transport wheels, so that the loading device can be attached in the manner of a combine harvesting machine for transport to a tractor. The transport wheels can be integrated into the loading device in such a way that a bottom support is achieved via them when using the loading device so that vertical forces are absorbed by the wheels during the insertion into the field crop heap. Preferably, however, the transport wheels are retractable and are thus not claimed in the tuber fruit loading process.

According to a particular aspect of the present invention, a belt conveyor is connected laterally to the loading device, via which the laterally challenged crops can continue to be guided. This belt conveyor can be connected via a pivoting frame with the loading device, so that the belt conveyor is pivotable in different delivery positions and preferably also in the vertical direction as required positioned. This lateral belt conveyor may be constructed such that it can be brought into a non-use position for transporting the loading device. The lateral belt conveyor device is preferably provided with a discharge section which, as such, permits height adjustment of the discharge edge. In the region of this drainage section, a guide device can be provided which leads the outflowing fruits even further. This guide device can be made in particular as a tubular pin made of an elastomeric material and pick up the falling sloping from the drainage fruit fruits and lead. The drainage section is preferably foldable.

The following transverse rollers 9, 8, 7, 6, 5 are designed as a cross-feed rollers rotate partially in opposite directions and a total of the spoon roller flowing tuberous crops in the representation to the right, ie shift towards the horizontal band section 12A out. The crops accumulating on this horizontal belt section 12A are then conveyed to the left by that belt section 12A and then transferred to the belt section 12B rising within the gap between the side rails 2a, 3a.

The loading device according to the invention comprises a support frame, which can not be seen here in greater detail, via which the connection points are provided, for connecting the device to the front lift of the tractor JB.

The device is designed so that its configuration can also be changed so that the delivery of crops can be done by simple conversion on the right side.

FIG. 2 shows a similar variant of a loading device according to the invention for loading tuberous crops in plan view. This loading device forms a blade-like insertion head of a front, designed here as a spoon roller underfeed structure 1, a left side region 2 and a right side region 3 and on the Unterschubstruktur 1 along a heap dismantling direction R or under a not detailed crop bedding insertable here.

In the insertion head, in turn, a transverse roller assembly 4 is arranged here a plurality of transverse rollers 5, 6, 7, 8, 9, 10, 1 1 comprises extending between the left and right side portion 2, 3 and are arranged spaced from each other that of soil that falls off the crops between the transverse rolls 5, 6, 7, 8, 9, 10, 1 1 can fall downwards.

The loading device here also comprises a conveyor belt device 12 which extends in a region lying behind the transverse rollers 5,... 1 1 and has a belt section 12B leading into the left side region 2 or beyond. According to the invention, the conveyor belt device 12 is integrated into the loading device such that it has a section rising in the conveying direction F in a region lying between the left and the right side region 2, 3. The transverse rollers 5... 1 1 are designed in such a way that they bring about a lateral displacement of the picked fruit towards a low horizontal input area 12A of the conveyor belt device 12. The transverse rollers 5 ... 1 1 are at least partially formed as conveyor spindles, for lateral displacement of the crops resting thereon. As can be seen, the transverse roller arrangement 4 and the conveyor belt device 12 are arranged such that the transfer of the crops to the conveyor belt device 12 takes place in a region offset from the center M of the insertion blade to the right side region 3. The conveyor belt device 12 is designed here in the region 12A as a screen belt through which any soil can fall down.

Again, the transverse rollers 5, ... 1 1 are coupled to a drive device not shown here and can be set in rotation via this drive means. The drive device comprises a connection gear which can be coupled to a PTO drive of a tractor.

The underfeed structure 1 is also designed here as a spoon roller and rotates so that the attacked Feldfürchte be raised and discarded inwardly on the device. The following in Knollenlaufrichtung the spoon roller 1 cross roller 1 1 is designed as a disk roller which meshes with the spoon roller. The subsequent transverse rollers 9, 8, 7, 6, 5 are designed as transverse transport rollers which rotate partly in opposite directions and, in total, the tuberous crops flowing in via the bucket roller in the representation to the left, i. shift towards the horizontal band section 12A. The crops accumulating on this horizontal belt section 12A are then conveyed to the right by that belt section 12A and then transferred to the belt section 12B rising within the gap between the side rails 2a, 3a.

The loading device according to the invention comprises a support frame, which can not be more clearly identified here, via which the connection points AI, A2, A3 are provided, for connecting the device to the front lifting of a tractor.

The loading device according to the invention comprises a chassis 15 with wheels 16, 17 through which the loading device can be towed. On a side opposite to the chassis 15 side a lockable drawbar is provided via which the Loading device can be attached to the tractor to approach, for example, another Verladepiatz. The drawbar is preferably incorporated into the loading device such that it can be brought into a non-use position when it is in operation and then does not jut out laterally or not far.

The crops raised within the intermediate region between the side cheeks 2, 3 over the band section 12B are transferred via a dropping step 18 to a further ascending conveyor belt 19. This conveyor belt 19 is tilt-adjustable supported and also pivotable about a vertical axis X. The laterally projecting conveyor belt 19 is pivotable in a non-use position, in particular in the interior of the loading device can be folded.

FIGS. 3a and 3b further illustrate the transport concept on which the loading device according to the invention is based. The crops migrating via the bucket roller or other undercarriage reach the cross roller arrangement 4. This transverse roller arrangement extends between a right and a left side region 3, 2 of a slide-in bucket. This slide-in scoop can be inserted over the front transverse edge region along a heap stripping direction R in or under a fruit pile. The transverse roller arrangement 4 comprises here not shown substantially horizontal and transversely to the degradation direction R arranged transverse rollers (see Fig. 1, reference numeral 5, ... 1 1) extending between the left and right side region (2, 3) and spaced from each other are arranged so that falling from the crops soil between the cross rollers can fall down. In a lying behind the transverse roller assembly area is a conveyor belt device 12 which extends in a lying behind the transverse rollers area, also transverse to the degradation direction R and has a side-promoting belt section 12B. The conveyor belt device 12 is integrated into the loading device in such a way that the belt section 12B already rises in the conveying direction in an area lying between the left and the right side region 2, 3. Via the transverse rollers 5,... 1 1, a lateral displacement of the picked fruits takes place towards a low-lying entrance area 12A of the conveyor belt device 12. Via the rising section 12B, the crops are transferred to an output conveyor 20. This includes a catch portion 20A, a rise portion 20B, and a discharge portion 20C. The output conveyor 20 is pivotable about a vertical axis Y. The catching section is still at least partially in the intermediate area between the side cheeks 2, 3, so that the picking up of the falling fruit from the rising belt 12B still takes place "within the blade width." The entire discharge conveyor 20 can be folded in. The belt section 20B is vertical on and The ejection section 20C can also be pivoted upwards and downwards.The adjustment of these sections takes place via an actuating hydraulics which can be controlled by the tractor.

The height profile of the transport device 12 and the output conveyor 20 is shown in FIG. 3b. The entrance area 12A is the lowest and serves to receive the fruits. The belt portion 12B guides the fruits upwardly within the blade width along an inclined path. The fruits dropped from the belt section 12B within the blade width are picked up by the output conveyor 20 and raised further. About the ejection section 20C, the fruits are dropped into a transport container, in particular a truck loading tray. The discharge level is preferably at least 2.50 above ground level.
