专利汇可以提供Soil compacting apparatus adapted to operate with rotating unbalances专利检索,专利查询,专利分析的服务。并且The invention concerns soil compacting apparatus which is adapted to operate with rotatable unbalance and which will be positively driven along a chain by means of a driven sprocket wheel, such chain spanning the soil surface to be compacted. The apparatus of the invention is characterized in that it comprises soil compacting apparatus which is adapted to operate with rotatable unbalance and which will be positively driven along a chain by means of a driven sprocket wheel, characterized in that said apparatus comprises a chain guiding system which is settable in a first position in which the chain will be maintained in engagement with the sprocket wheel in the zone of a circumferential sector, and which is movable from said first position towards a second position in which the chain can be detached from engagement with the sprocket wheel.,下面是Soil compacting apparatus adapted to operate with rotating unbalances专利的具体信息内容。

1. Soil compacting apparatus which is adapted to operate with rotatable unbalance and which will be positively driven along a chain by means of a driven sprocket wheel, characterized in that said apparatus comprises a chain guiding system which is settable in a first position in which the chain will be maintained in engagement with the sprocket wheel in the zone of a circumferential sector, and which is movable from said first position towards a second position in which the chain can be detached from engagement with the sprocket wheel, said chain guiding system being pivotable about an axis disposed perpendicularly to the sprocket wheel axis.
2. Soil compacting apparatus according to claim 1, characterized in that the chain guiding system is provided with two freely rotatable rollers which will determine the extent of the contact sector of the chain sprocket engaged by the chain.
3. Soil compacting apparatus according to claim 2 in which the chain guiding system is provided with a retaining plate having a curvature corresponding to the curvature of the chain sprocket and disposed between the rollers.
4. Soil compacting apparatus according to claim 1 including a switch for reversing the direction of the apparatus, tubular sections for actuating said switch, said tubular sections receiving said chain, said tubular sections being at positions upstream and downstream of said chain guiding system, means movably supporting said tubular sections in their longitudinal directions, and stop-abutments detachably mounted on the chain for engaging said tubular sections.
5. Soil compacting apparatus according to claim 4 including a switch lever that operates said switch, said tubular sections acting upon said switch lever, said switch lever having two positions on opposite sides of a dead-center middle idling position, and a spring for moving said switch lever from one of said two positions past said idling position and to the other of said two positions upon movement of said lever to said idling position.
6. Soil compacting apparatus according to claim 5 including an additional spring that is compressed by a tubular section a defined amount following which said additional spring will apply a force to actuate said switch lever.
7. Soil compacting apparatus according to claim 4 including sensing fingers on said tubular sections for striking obstructions in the path of the apparatus.
8. Soil compacting apparatus according to claim 1 in which said sprocket wheel axis is horizontal, means including an engine for driving said sprocket wheel, and said engine has a starting shaft that is vertical.
