Abstract
A compactor for compacting soil which can be controlled by hand using a bow-shaped control element or similar element. The compactor has a compacting or ramming working mass which is driven by a combustion engine back and forth, linearly, by a crank mechanism and a spring assembly. The compactor is also supported on the ground by a single-axle dolly.
Claims27
A manually guided tamping appliance for ground compaction comprising:
- a tamping implement having a working mass, a crank mechanism that is spaced from the working mass, and a spring assembly that is arranged between the crank mechanism and the working mass and that couples the working mass to the crank mechanism;
- an internal combustion engine which drives the working mass linearly back and forth via the crank mechanism;
- and
- an at least single-axle traveling gear that additionally supports the tamping implement against the ground, wherein
- the entire tamping element is dynamically movable as a unit relative to the traveling gear.
A manually guided tamping appliance for ground compaction comprising:
- a tamping implement having a working mass, a crank mechanism, and a spring assembly arranged between the crank mechanism and the working mass;
- an internal combustion engine which drives the working mass linearly back and forth via the crank mechanism;
- and
- an at least single-axle traveling gear that additionally supports the tamping implement against the ground, wherein the tamping implement is movable relative to the traveling gear;
- and a countermass capable of being driven by the engine in the opposite direction to the movement of the working mass over a large part of the range of movement of the working mass.
A manually guided tamping appliance for ground compaction comprising:
- a tamping implement having a working mass and a crank mechanism that drives the working mass to reciprocate linearly;
- an at least single-axle traveling gear that additionally supports the tamping implement against the ground;
- an internal combustion engine that supplies drive power to the working mass;
- a coupling that articulates the traveling gear to the tamping implement, the coupling being sufficiently flexible to permit limited dynamic movement of the tamping implement relative to the traveling gear;
- and
- a countermass that is driven by the engine in the opposite direction to the direction of movement of the working mass over a large part of the range of movement of the working mass.
A manually guided tamping appliance for ground compaction comprising:
- a tamping implement having a working mass and a crank mechanism that drives the working mass to reciprocate linearly;
- an at least single-axle traveling gear that additionally supports the tamping implement against the ground;
- an internal combustion engine that supplies drive power to the working mass;
- and
- an elastic coupling that articulates the traveling gear to the tamping implement, the coupling being sufficiently flexible to permit limited dynamic movement of the entire tamping implement as a unit.
