专利汇可以提供Vibratory compacting machine专利检索,专利查询,专利分析的服务。并且A vibratory compacting machine has a machine frame, at least two masses which are spring mounted relative to each other and to the frame, and a vibration exciting mechanism which is arranged to cause the masses to vibrate in a push-pull sense with respect to each other, the arrangement being such that the vibrations are substantially balanced and relatively little stress is placed on the machine frame. The masses may all be compacting tools which are sprung from the machine frame and are arranged to impact the ground. Alternatively one of the masses may be a compensating mass which is spring mounted between the machine frame and the other mass which forms a compacting tool. In a modification of this latter arrangement the compensating mass has portions which are also arranged to impact the ground so that the compensating mass doubles as a compacting tool. In an alternative arrangement the sensitive parts of the machine are mounted on the machine frame which is separated from the compacting parts of the machine by a flexible coupling which is connected to the compacting parts at the center of gravity.,下面是Vibratory compacting machine专利的具体信息内容。

1. A vibratory compacting machine comprising: a machine frame; a compacting tool; a compensating mass; spring means having a low spring stiffness connected between said frame and said compensating mass for supporting said mass from said frame; means connected to support said tool from said mass; and oscillating vibration means connected between, and to each of said compacting tool and said compensating mass for causing said mass and said tool to vibrate in phase opposition whereby no more than a small portion of such vibrations is transmitted to said frame.
2. An arrangement as defined in claim 1 wherein said compensating mass constitutes a second compacting tool of inverted U-shape, straddling said first-recited compacting tool and arranged to act on the same surface as the first-recited compacting tool.
3. A vibratory compacting machine comprising: a machine frame; a pair of first similar compacting tools; a second compacting tool disposed between said first tools and equal in mass to the sum of the masses of said first tools; spring means supporting each said tool from said frame; and oscillating vibration means connected between said frame and each of said tools for vibrating said first tools in unison with one another and in phase opposition to said second tool so that no more than a small portion of the vibrations is transmitted to said frame.
4. An arrangement as defined in claim 3 where said frame is a transportable vehicle.
5. A vibratory compacting machine comprising: a machine frame in the form of a tractive unit; a compactor unit having first and second compacting tools and spring means connected between said tools; oscillating vibration means connected between, and to each of, said tools for vibrating said tools in phase opposition; flexible coupling means connected between said tractive unit and said compactor unit and connected for delivering operating power to said vibration means, said coupling means being connected to said compactor unit substantially at the center of gravity thereof.
