Abstract

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 (2). The remote control device comprises an emitter unit (17), which can be displaced independently of the remaining vibrating plate and which can be detachably fixed to a draw bar (15). In a remote control mode, the emitter unit (17) is held by the user and displaced independently of the vibration plate. In a draw bar mode, the emitter unit (17) is placed on one end of the draw bar (15), so that the user can guide the vibrating plate by the pulling and pushing of robust control handles (19) on the emitter unit (17). The latter (17) can have at least one control handle (19), which can be used not only to input control commands for controlling the oscillation device (2), but can also be held by the user to manually guide the vibrating plate.

Description

Vibration plate with drawbar integrated in the remote control

The invention relates to vibrating plates according to the preambles of patent claims 1 and 3.

Vibratory plates for soil compaction are known in a variety of configurations. Common to the vibrating plates that they consist in principle of a lower mass and one of the lower mass via a spring device decoupled vibrational upper mass. The lower mass has a soil contact plate acting on the ground and a vibration exciter device mounted thereon. An essential component of the upper mass is a drive motor which drives the vibration exciter device on the lower mass in a suitable manner (mechanically, hydraulically). As a vibration exciter z. B. known per se and Zwei¬ wave exciter.

Fig. 1 shows a perspective view of a known vibration plate with a drawbar control.

On a ground contact plate 1, a vibration exciter 2 is mounted, which is driven by a drive 3, z. As an internal combustion engine is driven. The ground contact plate 1 and the vibration exciter 2 form a Unter¬ mass, while the drive 3 is attributed together with a frame 4 and a cover 5 of an upper mass. The upper mass is decoupled from the lower mass with the aid of intermediary feeder devices, not shown in FIG. 1, in terms of vibration.

On the cover 5 of the upper mass, a drawbar 6 is attached, which has ei¬ NEN drawbar handle 7, which is completed by a tiller head 8 shown only schematically. At the tiller head 8 two Steuer¬ handles 9 are pivotally supported. Hydraulikvent¬ can be controlled by means of the control handles 9, via which the phase position of rotating imbalances or Un- can increase waves in the vibration exciter 2 can be changed. As a result, the direction of a resultant of the imbalances in the vibration exciter 2, resulting force vector can be adjusted in a known manner to achieve a forward and reverse travel of the vibrating plate. Furthermore, the control handles 9 are designed so massive that the Bedie¬ ner can pull and pull them to change the direction of the vibrating plate during operation.

A chassis 10 only serves to transport the vibrating plate and is in operation without function.

For large, steerable vibration plates, it is possible that at least one of the unbalanced shafts is axially divided to control different imbalance masses such that a yaw moment is generated about a vertical axis of the vibration onsplatte to allow steering of the plate. In klei¬ neren, lighter vibrating plates usually a drawbar is provided with which the operator can perform the vibrating plate. In this case, the oscillation generating device not only generates the oscillations serving for soil compaction, but also a force component in the forward or backward direction. Accordingly, manual or Steuer¬ handles are provided on the drawbar, via which the operator can control the vibration exciter device in the desired manner to achieve the desired direction of travel. The steering and guiding the vibration plate takes over the operator by moving the end of the drawbar using the control handles or other hand movements.

Especially with larger, heavier vibration plates, it is now common practice to provide a remote control with the aid of which the operator can control the vibration plate without being in the immediate vicinity. This is particularly useful because heavy vibration plates introduce very strong vibrations into the ground which could damage a person standing directly next to them. In addition, the danger to the operator due to contact with the moving vibrating plate is lower due to the greater distance.

In practice, however, it has been found that the vibrating plates cause a wobbling, stochastic movement due to the strong vibrations and sometimes random counterforces due to the soil to be compacted. So it is often difficult to let the vibrating plate go straight ahead over a longer distance. Likewise, in practice, it requires the highest concentration of operator when the vibrating plate along a curve should drive. Accordingly, the operator must always make Lenkkorrek¬ tures, which often does not bring the desired results due to the very indirect effect of his Steuer¬ commands. Unlike z. B. on Vibrati¬ onswalzen the operator just can not directly influence the propulsion or a corresponding steering device in vibration plates. Rather, the operator can only influence the position of the imbalance masses in the vibration exciter, in the hope that ent speaking centrifugal forces arise, which pull the vibrating plate in the desired direction.

The remote control thus offers the operator only a very limited sensitivity. In particular, when the soil compaction work requires high precision, z. B. wanders on a curb, the operator will seek to manually guide the vibrating plate over the drawbar. Fernsteuer¬ bare vibrating plates but usually have no or, only a rudimentary trained guide drawbar, which makes it difficult due to often short He¬ bel manual guidance of the vibrating plate.

A solution to this problem could be that a Hybridsteue¬ tion is provided in which a vibrating plate is equipped in a classic way with a drawbar control, in which the operator manually guide the drawbar via control handles and can control the vibration exciter on the control handles. In addition, a per se known Fern¬ control provided, which is used when the operator does not want to run the drawbar. A disadvantage of this Hybrϊdsteuerung is that a very high construction cost must be operated, because on the one hand commander must be duplicated (control handles on Deichs¬ miserable and controls on a transmitter of the remote control). Furthermore, the transmitter is a separate part of the controller, which should be housed when not in use on the vibrating plate so that it can not be lost.

In a vibration plate produced by the applicant with the type designation "Wacker DPU 7060" instead of a drawbar a guide bracket is attached to the upper mass of the vibrating plate. Instead of operating elements, the guide bracket has a holder into which the transmission unit of a cable remote control can be inserted. The control of the swing - A -

excitation only takes place via the control elements of the cable remote control.

The invention has for its object to provide a vibrating plate, which is equally easy to handle in the remote control mode as well as manual Füh¬ in drawbar operation for the operator, the manufacturing costs should not be noticeably er¬ compared to known vibrating plates er¬.

The object is achieved by vibrating plates according to the An¬ claims 1 and 3. Advantageous developments of the invention are defined in the dependent claims.

According to the invention, a vibration plate having a lower mass and an upper mass in a conventional manner has a drawbar device connected to the upper mass and / or the lower mass. Furthermore, a remote control device is provided for controlling at least one forward or reverse drive by activating the vibration exciter device of the lower mass, with a transmission unit that can be moved independently of the remaining vibration plate. The transmitting unit can be detachably fastened to the drawbar device. At least one control handle is provided at the transmitting unit, which optionally serves for inputting control commands by the operator for the activation of the vibration exciter device and / or for gripping by the operator for manually guiding the vibrating plate.

Accordingly, the transmitting unit can be released from the drawbar device when the operator desires a remote control operation. If, on the other hand, it is necessary for precise compaction work to manually guide the vibrating plate, the transmitting unit can be fastened to the drawbar device. The operator then guides the vibrating plate exclusively via the control handles provided on the control unit. For this purpose, the operator can either generate control commands by actuation of the control handles with which the vibration exciter device can be adjusted in the desired manner, or manually influence the direction of travel of the vibration plate by pulling and pressing the control handles with its physical force. In this context, the term tiller device is used for a drawbar in which a drawbar rail is connected to the vibration plate at an articulation point, or for a guide bracket which is normally held at two articulation points on the vibration plate. A guide bracket thus differs strictly from a drawbar. However, if only the term "drawbar" is used below for the sake of simplification, it also applies equally to a guide bar with two articulation points.

Advantageously, at least one control element can be provided on the transmitting unit for inputting control commands by the operator for controlling the vibration exciter device. This corresponds to the classical structure of a transmitting unit.

In order to distinguish between the terms, it is defined that a later used handle serves only for mechanically guiding the vibrating plate, while a "control element" serves exclusively for inputting control commands for the vibration exciter, the drive or the like Due to its dimensioning (dimensions, strength), it is not suitable to accommodate larger executives If the operator tried to mechanically guide the vibrating plate via a control element, damage to the control element would have to be expected.

The term "control handle" can be distinguished from the terms "control" and "handle as follows: The control handle is on the one hand for controlling the vibrating plate by generating appropriate Steuersi¬ signals and adjusting the vibration exciter. On the other hand, the control handle is designed to be mechanically stable so that the operator can pull and press it to guide the vibrating plate, as is the case with a control lever of a classic drawbar control.

The term "guiding" in this context means the mechanical action of the operator by pulling or pushing. By contrast, "control" is understood to mean the generation of control signals for the vibration exciter and the drive, which in turn generate forces which move the vibration plate forwards or backwards or move it around a vertical axis (yaw axis) for steering purposes. In the solution according to claim 1, it is possible that on the drawbar über¬ no hand handle or a control must be provided. Rather, all operating elements are provided exclusively by the transmitting unit. In remote control mode, the control handle is used to generate appropriate control signals. In the drawbar operation with the transmitting unit attached to the drawbar, the control handle can also generate control commands. In addition, however, the operator can also take corrective action manually and in particular steer the vibrating plate by lateral forces.

In the variant specified in claim 3, a control element for inputting control commands by the operator is provided on the transmitting unit, while the drawbar device carries at least one control grip for gripping by the operator for manually guiding the vibrating plate.

The control handle should moreover be movable relative to the drawbar device. If the transmitting unit is attached to the drawbar device, the control handle is coupled to the control of the transmitting unit such that at a certain relative position of the control handle actuation of the control element of the transmitting unit is effected to generate control commands for driving the vibration exciter device.

The operator has in this embodiment of the invention the ability to operate the vibrating plate in a conventional manner by remote control using the controls present on the transmitting unit. Alternatively, he can put the transmitting unit on the drawbar device. On the drawbar fixed control handles are provided which can speak in principle ent¬ the control handles described above with reference to FIG. With the aid of, for example, a driver device, the movement of a control handle is transmitted to the control element of the transmitter unit assigned to it. This allows the operator in the drawbar operation the ability to operate the familiar, robust control handle in a known manner. However, while in the prior art, for example, hydraulic valves have been controlled in this way in order to control the vibration generator, the movement of the control handle or its relative position is now used to actuate the assigned control element of the transmission unit. This, in turn, then causes the control of the vibration in a conventional manner. supply causative. The arrangement thus simulates a classic drawbar control. The control handle itself also serves as a handle because it is robust enough to be pressed and pulled by the operator.

Since ultimately there is only one possibility of activation, namely via the transmitting unit of the remote control, which is also used by the control handle of the drawbar, considerable manufacturing costs can be saved.

In a particularly advantageous embodiment of the invention, the control handle is held in a holder for receiving forces introduced by the operator into the control handle on the drawbar device. The holder should be configured such that only a small part of the forces introduced by the operator to actuate the associated control actually acts on the control element and / or the transmitting unit, while the other, usually larger part of the forces of the Control handle is transmitted directly to the drawbar, without acting on the STEU erelement and / or the transmitting unit. If, on the other hand, the entire force applied by the operator could act on the control element or the transmitting unit, there would be a danger that these comparatively weakly dimensioned components would be destroyed. The holder ensures that even large forces of the operator are introduced as directly as possible into the drawbar, while only a change in the relative position (path change) of the control handle is transmitted to the transmitting unit and the control provided to it.

Preferably, the transmitting unit can be detachably integrated into the drawbar in order to protect it against damage from outside when not in use.

In a particularly advantageous embodiment, the drawbar on a connected to the upper mass and / or the lower mass drawbar and a subsequent to the drawbar spar tiller head. Da¬ it is particularly advantageous if the transmitting unit can be fastened in a receptacle in the tiller head or forms part of the tiller head or even the entire tiller head. This means that initially only the drawbar spar is part of the vibration plate when the vibration plate is operated in remote control mode and accordingly the sensor unit is removed from the vibrating plate. If, on the other hand, the operator fastens the transmitting unit to the drawbar spar, the transmitting unit assumes essential functions of a classic tiller head. In particular, the transmitting unit is then suitable to absorb forces applied by the operator for guiding the vibrating plate and to transfer it mechanically via the drawbar to the rest of the vibrating plate, so that the operator can very sensitively manually guide the vibrating plate without the actual remote control functions of the transmitting unit to have to take.

Furthermore, it may be advantageous if at least one handle is provided on the drawbar, for gripping by the operator for manually guiding the vibration plate. This construction is also known for vibratory plates, which conventionally have a drawbar control. By the invention, however, it is possible that the z. B. the tiller head .bil¬ transmitting unit with the help of the or the controls alone An¬ control of the vibration exciter takes over while mechanical Füh¬ tion forces of the operator alone on the handle on the drawbar über¬ carry, even if the transmitting unit on the drawbar is set up.

The various controls control element, control handle and handle, depending on the embodiment of the invention can be arbitrarily selected and combined. It is crucial that, on the one hand, a possibility for controlling the vibration plate in the remote control mode and, on the other hand, the options "controlling" and "guiding" in the drawbar operation are possible. Accordingly, the transmitting unit must be equipped with at least one control element or a control handle. If the transmitting unit has only control elements, suitable control grips, but preferably handles, must be provided on the drawbar in order to enable mechanical guidance. If the transmitting unit carries a control handle, however, no additional grips must be provided on the drawbar.

In a particularly advantageous embodiment of the invention, the vibration exciter device is designed in such a way that it generates a yaw moment about a vertical axis of the vibration plate, in order to produce the vibrating element. To steer tion plate. Such a construction is known per se from high-performance, remotely controllable vibrating plates.

According to the invention, it is particularly advantageous for this oscillation generating device to be controllable by the transmitting unit for setting the yawing moment when the transmitting unit is separated from the remaining vibrating plate. However, if the transmitting unit is attached to the drawbar, no yaw moment should be generated by the vibration exciter device. Then namely the steering of the vibrating plate is taken over exclusively by the operator, who manually guides the vibrating plate on the drawbar or the transmitting unit.

Advantageously, in the remote control device, a control command for steering the vibrating plate can be blocked when the transmitting unit is attached to the drawbar. In this way it is very easy to implement the above embodiment in which no yaw moment is to be generated by the vibration exciter device in the drawbar operation.

In a preferred embodiment, a fastening device is provided on the drawbar for attaching the transmitting unit to the drawbar such that any forces exerted on the transmitting unit by the operator are mechanically transferable to the drawbar. While in the case of previously known vibrating plates, at most a recess or a compartment was provided for accommodating the transmitting unit, the transmitting unit should now be able to form a stable mechanical connection with the drawbar. Then, the transmitting unit is able to transmit the forces acting on it by the operator on them without damage to the drawbar. Thus, the transmitting unit can also serve as a tiller head.

Furthermore, it may be advantageous if an electric charging device is provided, with an energy storage in the transmitting unit, z. As a battery, can be charged by a power supply from the vibrating plate when the transmitting unit is attached to the drawbar. Accordingly, the transmitting unit can be charged by the vibration plate whenever no remote control operation is required. This would make it possible that the transmitting unit would not have to be charged again separately from the vibrating plate. Advantageously, the signals in the remote control mode, when the Sen¬ deeinheit is separated from the vibration plate, from the transmitting unit via a cable route, an infrared link and / or a radio link to a provided on the vibrating plate receiver unit transferable.

If, however, the transmitting unit is fastened to the drawbar, it is advantageous to transmit the signals from the transmitting unit via a galvanic coupling, an optical interface or an infrared interface to the receiver unit provided on the vibrating plate. The galvanic coupling can z. B. be designed as a plug contact, so that the transmitting unit can be attached to the drawbar as a docking station. It is also possible to transmit the signals by radio (eg Bluetooth) even if the transmitting unit is attached to the drawbar.

In a particularly advantageous development of the invention. the drawbar between an operating position in which the operator z. B. in the drawbar operation on the drawbar handle forces on the vibration onsplatte exerts, and a remote control position in which the operator controls the vibrating plate only on the separate from the vibrating plate Sendeein¬, pivotable. Additionally or alternatively, the length of the drawbar between the operating position and the Fern¬ control position can be changed. This allows the operator to reduce the drawbar rail, in particular, if he wants to work for a long time only in remote control mode. The drawbar handle then does not present an obstacle during operation. However, if the operator wishes to work in drawbar mode, it is helpful for him if the drawbar rail extends with the transmission unit then placed at an ergonomically suitable height. Furthermore, it is desirable to achieve an appropriate length for the drawbar in the drawbar operation so that the operator does not have to apply excessively large guide forces due to the leverage effect.

These and other features of the invention will be explained with reference to the figures by way of example. Show it:

Technically known vibration plate with drawbar control; FIG. 2 shows a schematic perspective view of a vibration plate according to the invention in drawbar operation; FIG.

FIG. 3 shows the vibration plate of FIG. 2 in remote control mode; FIG. and

4 shows a detail of another embodiment of the vibrating plate according to the invention.

2 to 4 each show a vibrating plate according to the invention for soil compaction, which in many parts have an identical construction to the vibration plate already described above with reference to FIG. 1 and known from the prior art. Therefore, identical reference numerals are used for identical Bauele¬ elements. The arrangement of Untermas¬ se - consisting of a ground contact plate 1 and a Schwingungserre¬ ger 2 - and upper mass - with a drive 3, a frame 4 and a cover 5 - as well as between the upper mass and lower mass angeordne¬ th spring means for vibrational decoupling of the upper mass 2 to 4 correspond to the construction of the vibrating plate according to FIG. 1 known from the prior art from the lower mass. Therefore, reference is made to the above description of FIG Avoid repetitions.

According to FIG. 2, a drawbar 15 is attached to the upper mass, namely to the cover 5. The drawbar 15 has a substantially rod-shaped drawbar rail 16, at the end of which a transmission unit 17 is detachably fastened. The transmitting unit 17 therefore forms a tiller head of the drawbar 15.

Instead of the drawbar 15, a guide bracket may be provided, which is connected instead of at one of two articulation points with the upper mass. The following description of a vibrating plate with drawbar according to the invention can thus be readily transferred to a vibrating plate with guide bracket. Thus, vibration plates are also affected by the invention, which are equipped with a guide bracket to which a transmitting unit is releasably attached. The guide bracket and the drawbar thus differ only by the number of fastening points on the upper mass. The transmitting unit 17 is, as shown in FIG. 3, detachable from the drawbar 16 and can thus be moved separately from the rest of the vibrating plate. When the transmitting unit 17 is detached from the drawbar spar 16 (FIG. 3), it enables control of the vibrating plate in the remote control operation. On the other hand, if the transmitting unit 17 is placed on the drawbar 16, the control of the vibrating plate takes place in drawbar operation.

The transmitting unit 17 has a housing 18 which carries one or more control handles 19. The control handles 19 can be actuated by the operator and serve to specify control commands, which are ultimately conducted to the vibration exciter 2 or else to the drive 3 and there ent speaking, known per se Steuermaß measures to control the Vibrati¬ onsplatte effect.

The control handles 19 can z. B. lever whose pivot or Relativ¬ position in relation to the housing 18 is changeable. About suitable Auf¬ participants (Hall sensors, potentiometers, etc.), the relative positions or position changes are detected and converted into electrical signals. Of course, other controls, such. As buttons, switches, sliders, etc. attached to the housing 18 of the transmitting unit 17.

If the transmitting unit 17 is separated from the rest of the vibrating plate in the remote control mode according to FIG. 3, the predetermined control signals are transmitted wirelessly via an infrared or radio link or via a connecting cable to a receiver, not shown, usually provided on the upper mass of the vibrating plate , which converts the signals into corresponding control signals for the vibration generator 2 or the drive 3.

By way of example, an infrared eye 20 is arranged on the upper side of the upper mass, with which infrared signals from the transmitting unit 17 can be received in a known manner.

In the remote control mode according to FIG. 3, all control signals are transmitted by remote control from the transmitting unit 17. The operator does not touch the vibrating plate itself but can stand a few feet away from it. Of course, the vibrating plate should be steerable, ie, with be equipped with a vibration exciter, which makes a steerability by Er¬ generation of a yawing moment about the vertical axis of the vibrating plate ermög¬ light.

Since the drawbar 15 is inoperative in remote control operation and can not be reached by the servant, it is inventively provided that the drawbar 16 is either folded up into a rest position or is shortened in its length. For this purpose, the drawbar member 16 could be designed similarly to a telescopic rod. Of course, a Aus¬ is also possible management in which the drawbar handle 16 is both foldable and shortened to reduce it so that it no longer represents an obstacle in Fern¬ control operation, while it is unfolded in Deichselbe¬ drive and optionally extendable ,

In various soil compaction work, z. B. in a precise edge compaction on a curb, it is often desirable for the operator, the vibrating plate not only on the Fern¬ control, but also manually by their own force to lead. For this it is advantageous for him, if he can stand directly on the machine and no longer has to operate the vibration plate via the transmitting unit 17 as a remote control.

Accordingly, as shown in FIG. 2, it is possible to set the transmitting unit 17 on the end of the drawbar 16. Of course, the drawbar 16 should then stand for the drawbar operation in an operating position with sufficient length, as shown in Fig. 2.

The transmitting unit 17 can be locked on the drawbar spar 16 in a mechanically robust manner by means of a fastening device (not shown).

As before, the operator can then use the control handles 19 to give control commands for the vibration generator 2 with regard to forward and reverse travel. On the other hand, steerability should not be possible in the drawbar operation that has now been carried out in order to exclude a surprising rotation of the vibrating plate and an associated danger to the operator. Of course, but in another embodiment The invention also causes a rotation or steering of the vibrating plate by means of the control handles 19, if this is expedient in practice.

The control signals generated with the control handles 19 are in Deichselbe¬ drive via a suitable interface, for. B. via a galvanic coupling (plug contacts, similar to a laptop on a docking station), a opti¬ cal interface, an infrared interface or a short-range radio interface (Bluetooth) transmitted to the receiver on the vibration plate. The vibrating plate-side part of the interface can be arranged inside the drawbar 16, but also in other areas of the upper mass in order to protect it from external influences.

As shown in FIGS. 2 and 3, the control handles 19 are very large and robust. They are similar in design to the control handles 9 according to FIG. 1 and are therefore also suitable for absorbing mechanical forces. The operator can therefore pull on the control handles 19 and shred to influence the direction of travel of the vibrating plate and to guide the vibratory plate in this way more precisely than is usually possible with remote-controlled vibrating plates.

The control handles 19 may be made of metal, but also of high-strength plastic, so that they have no excessive weight despite their dimensions, which could be unpleasant for the operator especially in remote control operation, in which the transmitting unit 17 is to be borne by the operator.

In order to improve the guidance possibilities for the operator, additional handles can be provided on the drawbar rail 16 or on the housing 18 of the transmission unit 17. These handles, not shown, then serve only for holding and guiding the operator, but not for prescribing control signals.

The operator thus has the option of switching between drawbar and remote control operation at any time. For this purpose, he only has to attach or disconnect the transmitting unit 17 to the drawbar 16. Fig. 4 shows schematically a detail of another Ausführungs¬ form of the invention, in which a transmitting unit 21 is provided, which may be smaller in size and has a lower mechanical stability than the transmitting unit shown in Figs. 2 and 3. The transmitting unit 21 carries one or more controls 22, the z. B. by lever, slide or button can be formed.

In contrast to the control handles 19 of the transmitting unit 17, the control elements 22 are smaller and dimensioned with lower mechanical strength. They are only suitable for inputting control signals, but not for powerful gripping by the operator in order to manually guide the vibration plate during the process.

So that the operator has the opportunity to change the direction of travel of the vibration plate in the drawbar operation and to steer the device, 16 control handles 23 are attached to the drawbar handle.

The control handles 23 are similar to the control handles 19 of FIG. 2 and 9 of FIG. 1. They are attached tion at the end of the drawbar 16 in a not shown detention and robust, so that the operator with any force and pull them can press. In addition, the control handles 23 are movable relative to the drawbar 16, i. in particular pivotable about the axis with which they are held on the drawbar handle 16.

At the control handles 23, two fingers 24 serving as a driver device are provided which pivot with pivoting of the control handles 23. The fingers 24 are arranged at locations where also control elements 22 of the transmitting unit 21 are arranged, when the transmitting unit 21 is fastened to the front of the drawbar 16. The fingers 24 simulate the fingers of the operator and, with a corresponding displacement of the control handles 23, can actuate the associated control elements 22 on the transmission unit 21, so that the vibration exciter 2 is then adjusted in the desired manner.

In this process, the operator grips the control handles 23 in the usual manner, for example in their upper area. If he pivots one of the control handles 23 towards the front, the corresponding control element 22 is actuated via the assigned finger 24. Of course, the entrainment device can also be embodied such that a pulling of a control handle 23 toward the rear, in the direction of the operator, is also transmitted to an associated control element 22.

In a variant not shown, the control element 22 is formed by a lever (joystick). Here, too, the entrainment device can be designed such that the movement of the control handle 23 is transmitted directly to the lever and alters its position in the desired manner.

The control handles 23 are thus not directly coupled to the vibrator 2, as e.g. in the prior art of Fig. 1 is the case. The control handles 23 are not used directly for adjusting Hydraulik¬ valves or for activating actuators. Rather, their position or movement is transmitted in a relatively simple manner to the operating elements (control elements) of the transmitting unit 21, from where the corresponding control signals are output. Of course, further variants are conceivable in which e.g. the transmitting unit 21 is not placed in front of the control handles 23, but spatially therebetween.

The holder of the control handles 23 should be designed such that no high forces in the controls 22 or the transmitting unit 21 can be initiated. Therefore, the holder is equipped with suitable stops (also fe¬ derbehaftet), so that a considerable part of the forces introduced by the operator is introduced directly into the drawbar 16, without being guided by the transmitting unit 21. Furthermore, racking elements can be provided in the holder in order to be able to carry out the pivoting of the control handles 23 ergo nomically against a corresponding frictional resistance NEN.

Also, the transmitting unit 21 can be removed from the drawbar member 16 to change to the remote control mode. Therefore, in the lower part of FIG. 4, the transmitting unit 21 is also shown in remote control mode - separated from the rest of the vibrating plate. In Femsteuerungsbetrieb serve the control handles 23 only as handles, since they then - because of the lack of interposition of the transmitting unit 21 - perform any control functions in the sense of the above definition nen nen and are only to be used by the operator to guide.

In drawbar operation - with the transmitter unit 21 attached - the control signals are transmitted from the transmitter unit 21 via a suitable interface to the vibration plate, as already described above in connection with the transmitter unit 17 in the case of the vibration plate of FIG.

In addition to the already described components, other known components are also provided in or on the transmitting units 17 and 21, such as, for. B. an energy storage (battery). The battery can be charged in a particularly advantageous manner whenever the transmitting unit 17, 21 is placed on the drawbar handle 16. Then energy can be transferred from the rest of the vibrating plate to the transmitting unit to charge the battery. Furthermore, the transmission units 17 and 21 can be equipped with a belt for improving the wearing comfort as well as other buttons and switches, as is the case with conventionally constructed remote controls for vibration plates.

The vibrating plate according to the invention is shown only schematically in the figures. Of course, it is easily possible that the Deich¬ selholm 16 is further pivoted backwards, in the direction of the operator to allow him a comfortable guiding the vibrating plate.
