Vibrating plate comprising a remote control that is integrated into a draw bar
View Patent ↗The invention relates to a vibrating plate for ground compaction, said plate comprising a remote control device for controlling at least one forward or rear journey by the excitation of an oscillation device. The remote control device comprises an emitter unit, which can be displaced independently of the remaining vibrating plate and which can be detachably fixed to a draw bar. In a remote control mode, the emitter unit is held by the user and displaced independently of the vibration plate. In a draw bar mode, the emitter unit is placed on one end of the draw bar, so that the user can guide the vibrating plate by the pulling and pushing of robust control handles on the emitter unit. The latter can have at least one control handle, which can be used not only to input control commands for controlling the oscillation device, but can also be held by the user to manually guide the vibrating plate.
1. A vibrating plate for soil compacting, comprising:
a lower mass that has a soil contact plate and a vibration exciter device;
an upper mass that is coupled to the lower mass via a spring device and that has a drive;
a drawbar device that is connected to at least one or the upper mass and to the lower mass; and comprising
a remote control device for controlling at least a forward or backward travel by controlling the vibration exciter device, the remote control device having a transmit unit that is capable of movement independently of the rest of the vibrating plate; wherein

7. The vibrating plate as recited in claim 1 , wherein the drawbar device has a drawbar having a drawbar boom that is connected to the upper mass and/or to the lower mass, and a drawbar head connected to the drawbar boom.
8. The vibrating plate as recited in claim 7 , wherein the transmit unit is capable of being fastened in a recess in the drawbar head.
9. The vibrating plate as recited in claim 7 , wherein the transmit unit forms at least part of the drawbar head.
10. The vibrating plate as recited in claim 1 , wherein at least one handle is provided on the drawbar device for grasping by the operator for the manual guidance of the vibrating plate.
11. The vibrating plate as recited in claim 1 , wherein the vibration exciter device is fashioned such that it is capable of producing a yaw moment about a vertical axis of the vibrating plate in order to steer the vibrating plate.
12. The vibrating plate as recited in claim 11 , wherein
the vibration exciter device is capable of being controlled by the transmit unit in order to adjust the yaw moment when the transmit unit is separated from the rest of the vibrating plate, and wherein
no yaw moment can be produced by the vibration exciter device when the transmit unit is fastened to the drawbar device.
13. The vibrating plate as recited in claim 1 , wherein, in the remote control device, a control command for steering the vibrating plate is capable of being blocked when the transmit unit is fastened to the drawbar device.
14. The vibrating plate as recited in claim 1 , further comprising a fastening device for fastening the transmit unit to the drawbar device in such a way that all forces exerted on the transmit unit by the operator are capable of being mechanically transmitted to the drawbar device.
15. The vibrating plate as recited in claim 1 , further comprising an electrical charge device for charging an energy storage unit in the transmit unit via a supply of current from the vibrating plate when the transmit unit fastened to the drawbar device.
16. The vibrating plate as recited in claim 1 , wherein, when the transmit unit is separated from the vibrating plate, the signals are capable of being transmitted from the transmit unit via at least one of a cable path, an infrared path, and a radio path to a receiver unit provided on the vibrating plate.
