Problems solved by technology

However, any deformation of the material in this area is particularly undesirable since a deformed ejector is difficult to remove from the base unit for replacement
[0004] Another issue concerns the widespread use of ejector plates not made by the original manufacturer, which do not have sufficient strength characteristics to be used as replacements

Embodiment Construction

[0032] The same components are provided with the same reference numerals in the various exemplary embodiments.

[0033] figure 1 A front-loading ground milling machine 1 is shown comprising a centrally placed milling drum 2 within a drum housing 3 . The working direction (forward direction) is indicated by arrow "a". Ground milling machine 1 also comprises machine frame 4, and this frame 4 comprises console 60 and crawler type travel device 61, and crawler type travel device 61 is installed on the machine frame 4 by lifting column, so that vertical adjustment (here can also wheeled chassis as an alternative).

[0034] In operating mode, the ground milling machine 1 travels on the ground 62 in the working direction "a" of the machine, during which ground material is milled off the ground 62 by the milling drum 2 set in rotation. Due to the rotation of the milling drum 2, the milled material is thrown from the drum shell 3 to a conveyor belt 6 communicating with the drum shel...

Abstract

Described is an ejector unit for a milling drum of a mobile ground preparation machine comprising a discharge side and a reverse side that is opposite to the discharge side. It comprises a basic unit on the drum and an ejector plate, which is held on the basic unit by means of screw-threaded bolts. There is a positive fit between the basic unit and the ejector plate, which positive fit involves at least one pin, on the one hand, and at least one complementary cylindrical counterbore on the other hand, whereby the at least one pin and the at least one ejector are oriented so as to be coaxial to the longitudinal axis of the screw-threaded bolts. Preferably, a shoulder is also provided along the base of the basic unit on its side facing the ejector plate, and the ejector plate has at least one complementary shoulder, whereby the shoulder on the basic unit and the at least one shoulder on the plate have meshing regions, which in the mounted state prevent transverse displacements in three directions.

Description

technical field [0001] The invention relates to an ejector unit for a milling drum of a mobile leveling machine, the ejector unit comprising a base unit on one side of the milling drum and a replaceable ejector plate having a ejection side and an opposite side to the ejection side The opposite side of the positioning, and the ejector plate is detachably mounted to the base unit by bolts. Background technique [0002] Mobile soil preparation machines of this type include cold planers, stabilizers, surface miners and reclaimers, which are used in particular in the field of paving equipment and are covered by the term "soil preparation machine". The work-performing part of the machine comprises a milling drum with a plurality of cutting tools, in particular milling bits. The cutting tools are usually arranged along a helix on the surface of the milling drum, the helix corresponding to a left helix on one half of the milling drum and a right helix on the other half of the milli...
