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。
