Definitions
- the present invention relates to a collecting vehicle for waste and the like a rotary drum forming a collecting container, in the interior of which a screw conveyor is arranged, a drum drive for driving the rotary drum and a control device for controlling the drum drive.
- the garbage z. B. via a lifting and tipping device tipped into the rotating drum and from the press screw arranged therein be transported further inside the rotary drum. This is done at every loading point the rotary drum to a predetermined speed of z. B. brought six revolutions per minute. When driving on the drum switched off again.
- the present invention is therefore based on the object of an improved Collecting vehicle of the type mentioned to create that disadvantages from Avoids prior art and further develops the latter in an advantageous manner. In particular high reaction forces to the substructure and the substructure should be avoided be spared.
- the control device is designed such that that the rotary drum when driving between individual loading operations with opposite the reduced speed charging is rotatable.
- the control device contains a driving program as well as a loading program, which the speed of the Set the rotating drum differently.
- the rotating drum is rotated at a reduced speed.
- a recording point will turn the rotary drum to the usual speed brought the loading process. Because the rotating drum does not always come from a standstill must be approached or braked on these are due to the speed change resulting reaction forces and moments much smaller.
- the substructure of the collecting vehicle is protected.
- the permanent Turning the drum achieves an improved loading performance or payload.
- a detection device for detection operation and for recording charging processes.
- the control device controls as a function of the detected operating state the drum drive, d. H. it determines its speed.
- the Switching the speed of the rotary drum according to the driving speed of the collecting vehicle For this purpose, a vehicle speed sensor, in particular a drive shaft speed sensor for detecting the speed of the drive shaft of the collecting vehicle.
- a vehicle speed sensor in particular a drive shaft speed sensor for detecting the speed of the drive shaft of the collecting vehicle.
- the control device is designed such that the Drum speed controlled independently of an engine speed of the collecting vehicle becomes.
- a fixed drum speed for driving can be set, for example two revolutions per minute.
- a fixed drum speed regardless of the engine speed can be set, for example six revolutions per minute.
- the drum drive can basically be designed differently. Various Drive principles are possible.
- the Drum drive a hydraulic drive with a variable pump, the flow rate is adjustable by means of an electrical adjustment device. Through the electrical Adjustment device can be easily controlled by the electronic control device done here.
- the variable pump is preferably infinitely adjustable trained so that the delivery volume of the pump can be varied continuously and accordingly the speed of the rotary drum is infinitely variable.
- the Delivery volume of the variable displacement pump can be converted into a mechanical one by means of a hydraulic motor Drive movement implemented and by means of a reduction gear be given the rotating drum.
- a proportional magnet can be provided as the adjusting device be connected to the variable displacement pump. This can be done in a simple manner a control signal from the control device into a corresponding delivery volume the variable displacement pump and thus converted into a desired speed of the rotary drum become.
- the refuse collection vehicle 1 shown in FIG. 1 has a collection container Rotary drum 2, which is rotatable on a substantially horizontal axis Substructure 3 of the vehicle 1 is mounted.
- the rotary drum 2 is from the rear of the Vehicle loadable. Inside the rotary drum 2 is known per se A press or conveyor screw 4 is provided, with the help of which in the rotary drum 2 given groupage can be transported and pressed.
- the rotary drum 2 can be rotated by means of a hydraulic drive 4 become.
- the hydraulic drive 4 comprises a hydraulic motor 5, the mechanical Output movement by means of a planetary gear 6 on the drive shaft of the Rotary drum 2 is transmitted.
- the hydraulic motor 5 is fed by a variable displacement pump 7, which is driven by the cardan shaft 8 of the garbage truck 1 is driven (see FIG. 2).
- the variable displacement pump 7 is connected by hydraulic lines 9 and 10 to the hydraulic motor 5, so that this can be operated in a closed hydraulic circuit.
- the delivery volume of the variable displacement pump 7 is infinitely adjustable.
- a proportional magnet 11 is provided which has an electrical adjustment device forms for the variable displacement pump 7. The proportional magnet 11 does this Swing out the variable pump and can thus adjust its delivery volume as well as its conveying direction to switch the rotary drum 2 forward and to be able to run backwards.
- the proportional magnet 11 is controlled by an electronic control device 12.
- the control device 12 receives signals from a speed sensor 13 which the speed of the propeller shaft 8 and thus the driving speed of the garbage truck 1 recorded.
- the control device 12 thus controls the speed of the rotary drum 2 as a function of the driving speed of the refuse vehicle 1, specifically in such a way that with the vehicle at a standstill, the rotary drum 2 for loading operations about six revolutions per minute.
- driving d. H. if that Garbage truck 1 reaches a predetermined driving speed, the drum speed the rotary drum 2 reduced to about two revolutions per minute.
- the control device 12 operates as follows: From the propeller shaft 8 13 speed pulses are detected by the speed sensor and into a magnetic current converted, which is given to the proportional magnet 11, such that over the entire speed range of the usually designed as a diesel engine Drive motor of the garbage truck 1 a constant defined flow is generated on the variable pump 7, the desired drum speed at Driving operation causes. When the vehicle is stationary and the PTO shaft 8 on the other hand, the full current for the control magnet 11 is generated, so that the Variable pump 7 swings out fully, producing its maximum oil flow and thus the desired drum speed for loading operation.
- the control of the proportional magnet 11 by the control device 12 is preferably carried out via a function curve stored in it.
