The invention relates to a hand tamper for tamping ballast of a track, including a drive motor for rotation of an imbalance and, fastened to a lower end of a barrel which is connected to the drive motor and has a longitudinal axis, a barrel tip which is approximately V-shaped in longitudinal section.
A hand tamper of this type is already known according to DE 20 2014 003 655.1 U and has a sleeve which is pushed onto a barrel in the longitudinal direction thereof. At the end spaced from the drive motor, the sleeve has a tamping blade consisting of two diametrically opposed blade elements projecting from the sleeve.
It is the object of the present invention to provide a hand tamper of the kind mentioned at the beginning with which an improved work result becomes possible.
According to the invention, this object is achieved with a hand tamper of the specified type by means of the features cited in the characterizing part of the main claim.
A barrel tip configured in this way offers the advantage that the vibrations produced by the imbalance can be transmitted in a significantly better manner via the barrel fins to the ballast to be tamped. The embodiment according to the invention proves particularly efficient and suitable to deliver an optimal work result especially when used in a soiled ballast bed.
Additional advantages of the invention become apparent from the dependent claims and the drawing description.
The invention will be described in more detail below with reference to embodiments represented in the drawing in which
