DE20301998U1 - Device for removal of wire pieces from organic material left after harvesting of hops - Google Patents

Abstract

The mixed material (8) is transported from a chopping unit (4) into a separate smaller housing (7) attached to the front for being divided into metal scrapings (13) and material to be composted (14). The mix (8) is dropped on a drum (9, 10, 11) fixed in an inclined position, rotating clockwise, and provided with a magnetic element (12). The organic matter (14) is moved into a transport area (15, 16, 17, 18) by the forces of gravity while the wire particles (13) stick to the drum (9, 10, 11, 12) and can be released into a waste receptacle.

Device on hop picking machines

The innovation relates to a device according to the preamble of claim 1.

DE 197 40 791 A1 discloses a device on hop picking machines for sorting out pieces of wire that remain in the waste vine when the hop vines are chopped. In this device, a magnetic drum or magnetic roller is arranged in the transport path of the chopped vines, over which all of the chopped vine material is guided and on which the vine material is separated into organic vine material and pieces of wire. Such a device takes up a certain amount of space within the frame of the hop picking machine, which in conventional commercially available machines such as those manufactured by the applicant is sometimes somewhat tight depending on the type of construction. Furthermore, the distance on the circumference of the drum that is available for removing the pieces of wire may not be sufficient in practice, under certain circumstances, to pull the resulting pieces of wire out of the waste vine material when picking at high rates.

The aim of the innovation is to move the device for removing such wire pieces from the machine to the outside and to increase the separation distance available for separating the wire pieces from the vine waste in order to ensure that the wire pieces are separated properly.

According to the innovation, this is achieved with the features of the characterizing part of claim 1. Further embodiments of the innovation are the subject of the subclaims.

In order to sort out the pieces of wire or wire pins that are present in the chopped hop waste, the new design uses a rotating conveyor belt with a magnetic device attached to the underside of the upper strand, which is set at an angle at which the waste hop material moves against the direction of travel of the belt.

A21000DOC ·.· ...

moves or rolls downwards, whilst the pieces of wire are carried along in the direction of travel by the magnetic attraction of the magnetic device and are dropped off at the deflection point. The magnetic device can be designed in such a way that, for example, a magnetic plate or individual magnets are arranged within the upper run of the conveyor belt, distributed lengthwise and/or crosswise, i.e. the magnetic device is stationary, so that the pieces of wire are carried along by the conveyor belt in the direction of travel by the magnetic force and are dropped off or fall off at the deflection roller. The pieces of wire conveyed upwards by the conveyor device to the drop-off point run over the deflection roller. So that the pieces of wire can be separated out perfectly at this deflection roller, the deflection roller is designed as a magnetic drum, the magnetic effect of which is canceled out at the discharge point, so that the pieces of wire are no longer held by the rotating drum, but fall downwards due to their own weight. In this way, the pieces of wire or wire pins that respond to the magnetic device are separated from the non-magnetizable organic vine material and disposed of by being transported away via a conveyor belt or being fed into appropriate transport containers and then transported away. The green waste is sucked in by a blower and discharged via a duct.

So that the wire pin selection device does not take up space that is otherwise needed inside the hop picking machine, this device is, according to one embodiment, attached to the side and below the extraction rollers on the machine in a frame construction that is attached to the side wall of the machine. This makes it necessary to divert the chopped vine material leaving the extraction rollers with chopper with pieces of wire, so that this vine material first falls onto a transport device arranged in the vine material flow, e.g. a conveyor screw, and from there is guided into a housing that accommodates the wire pin selection device. The conveyor screw releases the chopped vine material with pieces of wire onto the circulating conveyor belt with a magnetic device at its end. The organic vine material passes from the conveyor belt via

a2iooo.doc ; ; ;,.

a chute downwards onto a screw conveyor, a conveyor belt or similar transport device which carries the organic vine material out of the machine, from where it is discharged via the blower.

According to a further embodiment of the innovation, the device is arranged at the rear of the hop picking machine if this should be expedient for space or other reasons, wherein the waste hops are discharged from the chopper onto a rotating conveyor belt or a scraper floor, from which the waste hops are discharged analogously to the previously described embodiment onto a rotating conveyor belt with a magnetic device assigned to the underside of the upper run and in a corresponding manner the wire pieces are separated from the organic vine material and disposed of.

The innovation is explained below in conjunction with the drawing using an example of implementation. It shows:

Fig. 1 is a schematic representation of a hop picking machine with wire pin selection device according to the innovation, in a view from behind,

Fig. 2 is a plan view of the representation according to Figure 1,

Fig. 3 is a schematic representation of a variant of a hop picking machine according to Figure 1 in a side view,

Fig. 4 is a plan view of the representation according to Fig. 3, and Fig. 5 is a schematic representation of a magnetic drum for the magnetic device.

The frame of the hop picking machine is designated 1, the machine 1 has a vine extractor 2 and extractor rollers 3, 3' with a subsequent chopper 4. The chopped vine material with wire pieces or wire pins leaving the chopper 4 downwards falls onto a transport device 5, e.g. a conveyor screw, a conveyor belt or the like, the discharge end 6 of which reaches an attachment structure 7 which is attached to one side wall of the machine. From the discharge end 6, the chopped vine material 8 with wire pieces is discharged downwards and falls onto a

rotating magnetic device 9 - 12, which consists of a conveyor belt 9, a driven magnetic drum 10, an idle roller 11, and a magnetic plate 12 or individual magnets, and which is set at an angle to the horizontal (the angle is e.g. 45° - the inclination can, however, be selected with a different angle or be adjustable if this should prove to be expedient in practice). The conveyor belt 9 is set in rotation in a clockwise direction via drive rollers 10, 11. Below the upper run of the belt 9, a magnetic plate 12 is indicated, which ensures that the pieces of wire or wire pins 13 contained in the waste material 8 are held in place on the magnetic belt 9 as they move, while the organic waste material rolls or falls downwards against the direction of travel of the belt due to the selected angle of inclination of the belt 9, whereby a chute 15 can be used to guide this organic vine material 14, which releases the organic vine material onto a transport device 16, which in turn transports the vine material out of the machine. The conveying device 16 can be, for example, a conveyor screw (or a conveyor belt or the like), at the end of which the vine material is sucked in by a blower 17 and discharged via a line 18.

In the modified embodiment according to Figure 3, the same reference numerals designate the same parts as in Figure 1. The transport device is shown schematically in Figure 3 as a scraper floor with brush slats or as a rubber studded belt. The attachment structure 7 or the housing is arranged at the rear of the machine instead of at the side of the machine as in Figures 1 and 2. The waste green waste 14 is sucked in by a blower 17 and discharged via a line, separated from the wire pins, in accordance with the manner shown and described in Figure 1, which is fed to a disposal belt or transport box.

Figure 5 shows the design of a magnetic drum, which represents the upper drive roller 10 of the conveyor belt 9. The magnetic drum 19 consists of a rotating outer drum 20 and a magnet 21 in partial cylinder form arranged stationary within the drum 20. 22 designates a dead center point at which the

The material to be separated (wire pieces) carried along by the magnet 21 on the rotating drum 20 is thrown off and collected on a separation belt (23) and carried away.
