Abstract

The milling roller system for manure spreaders has separating points (15) which allow the roller bearings (17, 18) to be removed from the roller core (9).

Description

The Invention relates to the milling drum a spreading device according to the preamble of claim 1.

beaters of the aforementioned type are on spreading vehicles, especially for agricultural Load, such as Barn manure, commonly known. They are subject depending on the load, very often an extreme wear. Further leads the touch with moist grit to rust on the surfaces, the by the decomposition in the grit contained organic matter and thereby formed aggressive substances, is amplified.

Of the Rust infestation weakens the material and also has many more As a result, the bearings on the trunnions that they can not be dismantled anymore.

at Reassembly or when replacing worn or on the bearings damaged milling drums, have to these, in the known spreaders of this kind, whose side walls because the high power requirement for reasons of stability without mounting slots for the milling drums accomplished be, as a complete unit, by disassembly at least a side wall to be mounted. The workload for this is very high, the consideration the drive elements increases the installation effort on. The spreader is more unstable than one with one piece Building structure.

The Invention has set itself the task of an easily assembled milling drum to provide that even during repair and maintenance work easy replacement of worn or defective parts Demand permits. This is characterized according to the invention achieved that the journals releasable with the middle piece, the working area of the milling drum, get connected.

The Invention will be described below by way of example and in the Drawings shown.

1 shows a mounted on the back of a scattering vehicle spreader with horizontally arranged milling drums.

2 shows a milling drum with their bearings (section AB).

One with horizontally arranged milling drums ( 6 ) equipped spreader ( 1 ) is at the rear end of the cargo space ( 26 ) of a suggestively illustrated spreading vehicle ( 25 ), on whose side walls ( 27 ), above a scraper floor ( 28 ), it consists essentially of the milling rollers ( 6 ), the side walls ( 2 and 3 ) and the cross-beam ( 16 ).

On the side walls ( 2 and 3 ) are bearing blocks ( 5 ), these take the bearings ( 17 and 18 ), each consisting of one, with a rolling bearing ( 23 ) equipped bearing housing ( 19 ) consist.

The with webs ( 20 ) provided bearing blocks ( 5 ) are formed such that a distance (e) to the side walls ( 2 and 3 ), the rolling bearings ( 23 ) before passing through the gap ( 21 ) still protects against migrating dirt.

In the storages ( 17 and 18 ) the milling drums ( 6 ), which consist of a centerpiece ( 9 ) and two trunnions ( 12 and 13 ), stored. The centerpiece ( 9 ), with a length (c), consists of an axle tube ( 8th ), which milling tools ( 7 ) and their supporting elements ( 22 ) and which at both ends with flanges ( 10 ) Is provided. With the flanges ( 10 ) the flanges ( 11 ) of the journals ( 12 u. 13 ), which are mounted first, by means of screws ( 24 ) connected with each other.

By means of a centering, or, a narrow centering approach ( 14 ), an axial alignment of the bearing pin ( 12 and 13 ) with the middle piece ( 9 ).

For versions with a spigot ( 14 ), the side walls ( 2 and 3 ) slightly spread outwards under slight pressure or the fixing screws ( 29 ) of the bearing housings ( 19 ) are something to relax.

The flanges ( 11 ) are of a concentrically arranged ring ( 4 ), which is part of the sidewalls ( 2 and 3 ) is enclosed. Between flanges ( 11 ) and wrestling ( 4 ) there are narrow gaps ( 21 ), the outlet of the grit to the outside, in particular for the protection of rolling bearings ( 23 ), largely prevented.

The length (c) of the middle piece ( 9 ) is equal, or advantageously a little less, than the distance (d), between the end faces of the rings ( 4 ), so is a mounting or dismounting of the center piece ( 9 ) easily possible.

The spreading work of the milling drums ( 6 ) is carried out by passing through the lateral side walls ( 27 ) limited loading space ( 26 ) Spreading material by means of the scraper floor ( 28 ) against the rotating milling drums ( 6 ) is pushed. These capture with their milling tools ( 7 ) the spreading material and throw it backwards on the ground.

In abrasive grit, such as chicken or turkey dung, a very strong Ver wear in the middle piece ( 9 ), the working area which is used for frequent replacement of the center piece ( 9 ) forces. The bearings ( 17 and 18 ) are mainly destroyed by pollution, which influences the lifetime differently with moist stray materials and depending on the aggressive, rust-promoting substances contained therein.

According to the redesign of the milling drum ( 6 ) In mutually detachable portions, it has become possible, instead of entire milling drums, only the used or defective portions to replace inexpensively with little effort, with the exchange of the center pieces ( 9 ) Assembly work on the drive, whether gear or chain transmission ( 30 ), can be omitted.
