Abstract

The device is attached at a fodder mixture car in tilted manner. A transverse conveyer system (21) is arranged between a rotatory grinder (9) of cutting device (6) and a conveyor pit (17) of a rotating arm (15). A silage gut is guided to a conveyor (16) from a difference area between removing width of rotatory grinder and a conveyor pit width.

Description

The invention relates to a device for feed removal from flax silos, which is pivotally mounted on a feed mixer wagon and at the outer end of its equipped with a conveyor swing arm carries a separator which separates the front silos flat silos and this passes a conveyor belt for forwarding in a mixing container, wherein the Entnahmebreite the milling drum, the delivery shaft width of the swing arm significantly exceeds.

Devices of this type are used on farms to remove cattle feed from flax silos. For removal of the feed, the removal device is attached to an end face of the flat silo in such a way at the upper edge that a feed strip is removed during lowering.

High-speed milling drills are generally used to remove the chuck, which by means of their shape and arrangement, possibly by supporting profiled throwing vanes or helical spirals, within the housing surrounding the milling drum, spin and shift from the larger removal width to the narrower chute width , The milling drums generally shed the forage undershot.

Oberschlächtig working or working with changing direction milling drums are known, but are mainly used where the feed is thrown directly by means of high speeds, and correspondingly high centrifugal forces, without additional conveying elements in a transport or mixing container.

Livestock feeding aims at maintaining a natural feed structure in order to achieve the best possible animal health and productivity. When taking silage feed, this can be influenced, it is therefore the optimization of the sampling device by changes to the working organs and their operation, sought.

In unterzuschächtig promotional milling drums which are more or less tearing and cutting separated from the cutting tines under high power requirements lining, leaving a roughened surface, first on the underneath the milling drum not yet detected part of the feed strip, reinforced by the stroke cylinder controlled downward movement of the swing arm, pressed and partly grated, then thrown into the drum shell and moved in the direction of the conveyor shaft. These processes are not optimally suited for maintaining the feed structure.

On the roughened cut surfaces of the flax silo, oxygen and moisture can more easily penetrate into the silage skirt than on smooth cut surfaces, which causes post-fermentation and leads to the loss of feed quality and structure.

The high tear speed of the milling drum, the grinding of the feed when sweeping over the not yet removed food strip, the high impact forces and transverse movements in the housing surrounding the milling drum, are also disadvantageous for maintaining the feed structure.

In a publication DE 10 2007 022 651 For the more gentle treatment of the feed structure, an embodiment is described which has clearing fingers arranged on spiral-shaped conveying elements, which penetrate into the silo rock and in so doing pull out feed therefrom. The feed is still taken unterschlächtig with high speed and high power requirements.

Another embodiment for gentle feed treatment, according to the European patent application EP 1712 123 A3 shows a arranged on a separate pivoting arm milling drum with an upstream cutting device, in this case, the separated feed is dropped into a mounted on another pivot arm receiving tray and fed in this arranged on this pivot arm conveyor belt. This elaborately designed design is heavier and more expensive than previous and requires an increased operating effort.

In order to obtain the feed structure as far as possible when removing it from flax silos, it is provided according to the invention to exercise the separation of the feed from the silage stick more exactly by means of a cutting device. Separately separated from the silage lining leaves a clean cut surface and can be gently transported, even with reduced speed of the milling drum, both a oberschlächtige, which advantageously extends in the overhead conveying without significant frictional losses, as well as a unterschlächtige feed removal is improved.

The subdivision of the milling process according to the invention, in a separation and removal process and the transfer of the transverse transport function of the milling drum on a downstream cross conveyor, except for the more gentle structural treatment of the feed also to a lowering of labor and energy costs and lower stress on the working organs.

The invention will now be described by way of example and illustrated in the drawings.

2 shows a plan view of the sampling device after the cutting path AB.

5 shows a further embodiment.

The device ( 5 ) for feed removal is on a self-propelled feed mixer ( 1 ) on its chassis ( 2 ) or mixing container ( 3 ) to the axis ( 4 ), by means of lifting cylinder ( 18 ) adjustable, pivotally mounted. It consists essentially of the swivel arm ( 15 ) and the separating device ( 6 ).

The on the axis ( 4 ) mounted swivel arm ( 15 ) is with a conveyor belt ( 16 ), which in a conveyor shaft ( 17 ), it carries at its outer end the separating device ( 6 ). The swivel movements are determined by the bearings ( 19 and 20 ) attacking lifting cylinder ( 18 ) controlled.

The separating device ( 6 ) consists of a housing ( 11 ) in its side walls ( 12 ) one with tines ( 10 ) occupied milling drum ( 9 ) and a transverse conveyor ( 21 ) are mounted and at the front ( 14 ) a cutting bar ( 7 ) is arranged, the at least one horizontally oscillating knife ( 8th ), which separates the silage with cutting teeth pointing downwards. At the bottom of the case ( 11 ) is a scraper bar ( 27 ) appropriate.

On the back wall ( 28 ) of the housing shell ( 13 ), which milling drum ( 9 ) and cross conveyor ( 21 ) partially surrounds, is the separation device ( 6 ) with the swivel arm ( 15 ) connected. The back wall ( 28 ) is in the connection area of the swivel arm ( 15 ) for feeding on the conveyor belt ( 16 ) with an opening ( 29 ) Mistake.

The relevant element of the cross conveyor ( 21 ) is with spiral screws ( 23 / 24 ) and throw paddling ( 25 ) occupied roller tube ( 22 ). The spiral screws ( 23 / 24 ) take over, by means of predetermined pitch and direction of rotation, the merging of in the difference ranges (E) of the wider milling drum ( 9 ) worn out food, for opening ( 29 ) in front of the narrower conveyor shaft ( 17 ), where it is from the throw paddles ( 25 ) on the conveyor belt ( 16 ) is placed. The spiral screws ( 23 / 24 ) run for better feed guidance in wells ( 26 ), which until the opening ( 29 ).

For feed removal, the feed mixer ( 1 ) with the over lifting cylinder ( 18 ) in the position (C) pivoted up separating device ( 6 ) to the top edge ( 31 ) of the flax silo ( 30 ) until the cutting bar ( 7 ) so far above the silo stick that when lowering a lining strip of thickness (H), along a cutting line ( 32 ), from the end face of the flax silo by means of the oscillating blade ( 8th ) is separated. The relatively slowly rotating milling drum ( 9 ) takes over the separated food and promotes it superficially and gently in the housing ( 11 ), with low power requirements, to the downstream cross conveyor ( 21 ), which uses its spiral screws ( 23 / 24 ) to the opening ( 29 ) of the conveyor shaft ( 17 ), where it is removed from the conveyor belt ( 16 ) and into the mixing container ( 3 ), where it is produced by mixing screws ( 33 ) mixed with other types of feed or components and then through a hatch ( 34 ) via a cross conveyor ( 35 ) is deposited laterally in a feed passage.

The cutting bar ( 7 ) can also be equipped with oscillating double blades or other proven versions of silage removal technology.

In an alternative embodiment, the milling drum by a milling belt ( 36 ) replaced, this design allows for otherwise equally gentle operation, a broadening of the thickness (H) of the abolished food strip.

A further simplified embodiment is shown without cutter bar, this embodiment is also suitable for the gentle feed removal, as the previous ones, if it is easy to remove silage to be removed. The roughening of the front wall is then negligible, if frequent fermentation, z. B. with frequent removal, can not develop.

An unterschlächtige Futterabtragung is possible in all the above embodiments, this must be the scraper ( 27 ) near the front wall ( 37 ) to avoid feed losses through a gap gap. The adaptation of the cross conveyor ( 21 ), ie the change in the direction of rotation, the adjustment of the conveying direction of the spiral screw and an adjustment of the trough ( 38 ), because of their undersized feed guide a larger passage to the milling drum ( 9 ) are necessary.
