专利汇可以提供Soil compacting machine专利检索，专利查询，专利分析的服务。并且A soil compacting machine has a frame carrying two soil compacting rollers mounted in tandem and at least two out of balance centrifugal force generators for vibrating the rollers as they roll the soil. At least one of the generators is mounted on the frame in front of the rollers and at least one other generator is mounted on the frame behind the rollers and both these generators are carried on shafts which extend longitudinally in the direction of travel of the machine and are relatively short compared with the width of the frame and the axial length of the rollers.，下面是Soil compacting machine专利的具体信息内容。
1. In a soil compacting machine including a frame, at least two soil compacting rollers, means mounting said rollers in tandem in said frame, at least two out of balance centrifugal force generators and means mounting said generators in said frame, the improvement wherein said generator mounting means includes first means mounting at least one of said generators in front of said rollers and second means mounting at least one other of said generators behind said rollers both said first means and said second means including a relatively short shaft extending in the direction of travel of said machine.
2. A machine as claimed in claim 1, wherein said means mounting said rollers in said frame includes horizontal axle means and further comprising bearing means mounting said shafts of said first and said second means at substantially the same height as said axle means.
3. A machine as claimed in claim 1, wherein said frame includes longitudinal side members and transverse members interconnecting said longitudinal side members in front of and behind said rollers, said transverse members including portions defining housings and said generator mounting means mounting said generators in said housings.
4. A machine as claimed in claim 1, wherein said frame includes longitudinal side members disposed one at each end of said rollers and further comprising engine means and drive means operatively connecting said generators to said engine, said drive means being located above said rollers and between vertical planes containing said longitudinal side members.
5. A machine as claimed in claim 1, wherein each of said generators includes a pair of unbalanced discs, means rotatably mounting said discs and means for rotating said discs in opposite directions to each other.
6. A machine as claimed in claim 5, further comprising peripheral teeth on said discs, said teeth of said discs in each of said pairs of discs meshing with each other.
7. A machine as claimed in claim 5, further comprising peripheral teeth on said discs and toothed belt means meshing with said teeth on said discs of each of said pairs.
8. A machine as claimed in claim 7, further comprising teeth on both sides of said belt, an idler roller, and means extending said belt around said idler roller, around one of said discs in said pair in a clockwise direction and around the other of said discs in said pair in an anticlockwise direction.
9. A machine as claimed in claim 1, further comprising means for driving said generators, means mounting said driving means on said frame and universally jointed shaft means operatively connecting said driving means to said generators.
10. A machine as claimed in claim 1, including engine means for driving said generators, means mounting said engine means on said frame, a hydraulic pump, means operatively coupling said pump to said engine means, at least two hydraulic motors, means operatively connecting said pump to said motors and means operatively connecting each of said motors to one of said generators.
11. A machine as claimed in claim 1, further comprising means for operating said generator in front of said rollers to produce a first oscillation frequency and means for driving said generator behind said rollers to produce a second oscillation frequency different from said first oscillation frequency.
12. A machine as claimed in claim 1, comprising at least two pairs of said generators, and means detachably mounting each of said pairs of generators on said frame.
