Definitions

the present invention relates to a milling system for making a laying slot in a ground surface, which has a carrier vehicle and a milling device which is arranged on the front side of the carrier vehicle, is connected to the carrier vehicle and a milling wheel, at least one hydraulic drive and a milling wheel housing with a front side of the milling wheel Ejection window on which a conveyor belt is provided during operation of the milling system.
Milling systems of this type are used in so-called trenching, in which a slot is milled in a road surface, an asphalt path or cycle path or in unpaved surfaces, in which micro-pipes or cables that can be buried are then inserted and which is then sealed with a filling compound.
Milling using the milling wheel enables asphalt, concrete and stone to be cut precisely and cleanly without damaging the trench wall of the trench created.
a milling machine of the type mentioned at the beginning was presented by the Simex company.
the advantage of the conveyor belt arranged at the ejection window is that the removal material produced during milling can be transported away on the conveyor belt.
the conveyor belt is provided at the front of the carrier vehicle, only relatively small and light conveyor belts can be used here, with which, for example, an excavator shovel, but not a truck on board, can be filled with the milled material, as the milling system would otherwise tip over.
an excavator with a large shovel has to travel along, which can then be unloaded from the excavator onto a truck. This is very cumbersome, time consuming and expensive.
a milling system for making a laying slot in a ground surface, which a carrier vehicle, a milling wheel arranged on the front of the carrier vehicle, connected to the carrier vehicle and having a hydraulic drive, and a milling wheel housing provided around the milling wheel with an ejection window provided on the front of the milling wheel a conveyor belt is provided during operation of the milling system, in which a downwardly extendable front hydraulic support cylinder is provided on the milling wheel housing in front of the axis of rotation of the milling wheel in front of the milling wheel's axis of rotation in a working position of the milling machine; In the forward direction of travel of the milling system behind the axis of rotation of the milling wheel, a rear hydraulic support cylinder which is vertically aligned in the working position of the milling system and can be extended upwards is provided; and a hydraulic balance cylinder is provided hydraulically coupling the front and rear hydraulic support cylinders.
the cutting wheel housing is provided around the cutting wheel at the top and side.
the milling wheel with the milling wheel teeth provided on it protrudes partially out of the milling wheel housing in order to be able to mill.
the milling wheel When the milling system is in operation, the milling wheel rotates clockwise when viewed from the right. Material milled off by the milling wheel teeth is carried along by the milling wheel when it rotates and is thrown onto the conveyor belt through the ejection window. The conveyor belt then transports the material away from the milling machine.
the conveyor belt is advantageously located in front of the cutting wheel and not to the side of the cutting wheel. Therefore, in the milling system according to the invention, the rotational movement of the milling wheel favors the ejection of material onto the conveyor belt.
the milled material does not have to be deflected to the side. Instead, the material is already ejected in the direction of removal.
the inventive arrangement of the conveyor belt in front of the milling wheel allows the excavated material to be conveyed by the conveyor belt directly to a vehicle traveling ahead.
the hydraulic cylinder arrangement provided on the milling system according to the invention ensures that the load on the front side, which is created by the conveyor belt and the material that is conveyed on the conveyor belt, is balanced so that the milling system does not twist or tilt or even tip over during operation.
the hydraulic cylinder arrangement stabilizes the milling system without having to increase the weight of the milling wheel housing.
the rear hydraulic support cylinder and the front hydraulic support cylinder are preferably designed as plunger piston cylinders.
the respective pistons in the rear hydraulic support cylinder, the hydraulic compensation cylinder and the front hydraulic support cylinder are each in a central position.
In the rear hydraulic support cylinder there is hydraulic fluid in a hydraulic area formed below the piston located therein.
In the front hydraulic support cylinder hydraulic fluid is located in a hydraulic area formed above the piston located therein.
hydraulic compensating cylinder there is hydraulic fluid both in the hydraulic areas above and below the piston located therein.
An upper hydraulic area of the hydraulic equalizing cylinder is connected to the lower hydraulic area of the rear hydraulic support cylinder via a hydraulic line.
a lower hydraulic area of the hydraulic compensating cylinder is connected to the upper hydraulic area of the front hydraulic support cylinder via a hydraulic line.
the piston rod of the rear hydraulic support cylinder protrudes upwards out of the relevant cylinder.
the piston rod of the front hydraulic support cylinder protrudes downward from the relevant cylinder.
a lower region of the cylinder of the rear hydraulic support cylinder is preferably pivotably connected to a lower milling wheel housing region located behind the axis of rotation of the milling wheel in the forward travel direction of the milling system.
An upper end of the piston rod of the rear hydraulic support cylinder is connected to an upper milling wheel housing area located behind the axis of rotation of the milling wheel in the forward direction of travel of the milling system.
a lower end of the The piston rod of the front hydraulic support cylinder is preferably pivotably connected to a lower milling wheel housing area located in front of the axis of rotation of the milling wheel in the forward direction of travel of the milling system.
An upper area of the cylinder of the front hydraulic support cylinder is connected to an upper cutting wheel housing area located in front of the axis of rotation of the cutting wheel in the forward direction of travel of the milling system.
the above-described, used, closed hydraulic cylinder arrangement thus has a self-leveling effect.
the milling wheel housing and also the milling wheel depth adjustment of the milling wheel are always held in a horizontal position, despite the additional weight due to the conveyor belt and the material lying or conveyed on it.
the milling system according to the invention compared to the prior art, it is possible to provide a longer conveyor belt with a correspondingly greater weight close to the milling wheel on the milling wheel housing in order, for example, to bridge the distance and the difference in height to a truck in front and this with the milled material to be able to load directly through the conveyor belt.
ventilators are provided on the front hydraulic support cylinder and on the rear hydraulic support cylinder.
the conveyor belt is at least 3 m long, particularly preferably at least 3.50 m long. Such a length is sufficient to be able to fill a truck with the milled material directly with the conveyor belt.
a conveyor belt of the conveyor belt is preferably at least 25 cm wide, particularly preferably at least 30 cm wide. With such a conveyor belt width, the milled material produced during milling can be efficiently picked up and removed.
the conveyor belt is pivotably mounted on the milling wheel housing and from the working position of the milling system, in which a rear end of the conveyor belt is located at the ejection window, into a holding or transport position of the milling system, in which the conveyor belt is attached to a Holding side of the milling wheel housing is held, and reversely pivotable.
the milling system is constructed in such a way that a horizontally aligned transport support for the conveyor belt, mounted on the milling wheel housing, protrudes laterally on the holding side of the milling wheel housing.
the conveyor belt can be placed on this transport support in the holding or transport position of the milling system and secured to it.
the Milling wheel housing is provided with a horizontally pivotable rotary pivoting device connected to the conveyor belt with a retractable and extendable inclination adjustment cylinder attached to it for the conveyor belt.
a horizontally pivotable rotary pivoting device connected to the conveyor belt with a retractable and extendable inclination adjustment cylinder attached to it for the conveyor belt.
the angle of inclination of the conveyor belt can preferably be adjusted hydraulically from a driver's cab of the carrier vehicle. This makes it possible for the milled material to be dropped from the conveyor belt onto trucks of different loading heights, whereby the loading capacity of the loading area of the respective truck can be fully utilized.
the inclination or angle of inclination of the conveyor belt can preferably be set in a range from 0 ° to 30 °, particularly preferably in a range from 0 ° to 45 °, with the aid of the inclination adjustment cylinder.
the same hydraulic drive as used to adjust the milling wheel can be used to control the tilt adjustment cylinder.
the milling system then advantageously has a hydraulic valve that can be electrically controlled and switched over from the carrier vehicle, for example via a joystick, and is integrated into the hydraulic supply of the inclination adjustment cylinder and the milling wheel drive.
the inclination adjustment cylinder is connected to both longitudinal support profiles of the conveyor belt. This prevents the conveyor belt from twisting.
a U-shaped fork can be provided, for example, at an end of the inclination adjustment cylinder facing the conveyor belt, which fork engages around the conveyor belt from above, the side struts of the U being attached to the longitudinal support profiles of the conveyor belt.
the inclination adjustment cylinder is preferably mounted on a support post profile of the rotary / swivel device that is vertically aligned in the working position of the milling system and can be swiveled on this.
the vertically aligned support post profile preferably forms a right angle with the tilt adjustment cylinder in the working position of the milling system.
a suitable height or inclination of the conveyor belt can also be set by the height of the support stand profile.
the conveyor belt is always held securely by means of the rotary pivoting device and the tilt adjustment cylinder provided on it, and the inclination of the conveyor belt can also be suitably changed while the conveyor belt is pivoted from the working position to a holding or transport position.
the holding post profile is connected via a holding angle profile construction to a swiveling post profile which is rotatable about its longitudinal axis and which is vertically aligned in the working position of the milling system. Due to the bracket profile construction, the bracket profile be positioned centrally relative to the conveyor belt, so that the conveyor belt can be held in a torsion-proof manner, although the swivel stand profile itself is attached off-center of the conveyor belt on the side of the milling system.
a support angle profile construction or support bracket that is guided around the back of a lower end of the conveyor belt and pivotable around the pivoting stand profile is provided on the swivel stand profile.
a kink protection is provided between the inclination adjustment cylinder and the conveyor belt in one embodiment of the milling system according to the invention.
the buckling lock can be designed, for example, in the form of a safety articulated linkage.
the kink protection increases the security of the mounting of the conveyor belt, which is advantageous, for example, when the conveyor belt is driven against an obstacle.
an ejection wedge or tooth aligned in the forward direction is provided inside the milling wheel housing, in front of and above the milling wheel, the underside of which forms an angle to the floor surface.
the bottom of the ejection wedge or tooth can be straight or concave. Due to the angle of the ejection wedge or tooth, the milled material is preferably directed in the direction of the conveyor belt and not taken along in its rotary motion by the milling wheel. The ejection is therefore forward.
the conveyor tunnels can, for example, have a height of 3 to 5 cm, preferably 4 cm.
the conveyor tunnels are preferably made of rubber or PVC fabric tape.
the conveyor tunnels can for example be vulcanized onto the conveyor belt. With the help of the conveyor tunnels, the throwing distance of the conveyor belt can be increased compared to using a conveyor belt without such conveyor tunnels.
the conveyor belt has a cover on its rear side. This ensures, for example, that no one comes into contact with the conveyor tunnels provided on the conveyed goods during operation of the milling system and no one can intervene in the running conveyor belt.
At least one opening is provided in a rear region of the milling wheel housing opposite the ejection window.
the opening can in principle be closed or closable by a flap.
this opening is preferably kept open during operation of the milling system. This results in a suction to the rear, whereby a lateral falling out of material from the milling wheel housing can be avoided or at least greatly reduced.
the carrier vehicle is a caterpillar or tracked vehicle. This results in a particularly high level of security against tilting the milling system. In principle, however, it is also possible for the carrier vehicle to have wheels.
An ejection hood which is open above the conveyor belt, is preferably attached to the ejection window.
the ejection hood extends the ejection channel so that the milled material can advantageously fall onto the conveyor belt.
the ejection hood preferably has an ejection hood cover extending in the direction of the conveyor belt and the discharge hood sides which are connected to or integrally formed therewith and taper towards the front and top. The sides of the ejection hood act as lateral scrapers.
the ejection hood is made of rubber.
a discharge flap made of flexible material is provided in front of a front end of the conveyor belt.
the discharge flap can for example be provided at a distance of 20 to 40 cm in front of the front end of the conveyor belt.
the discharge flap can be suspended, for example, on two spacer struts each fastened to the two longitudinal support profiles of the conveyor belt.
the discharge flap can be made of rubber, for example.
the hydraulic compensating cylinder is preferably provided, aligned obliquely between the front and rear hydraulic support cylinders.
the hydraulic compensation cylinder which can be longer than the front and rear hydraulic support cylinders, can be accommodated with the hydraulic hoses connected to it in the space between the front and rear hydraulic support cylinders that is present anyway.
the longitudinal support profiles, the drive roller and the deflection roller of the conveyor belt are made of aluminum.
the conveyor belt base frame can for example be made of aluminum compression elements. The construction of the conveyor belt elements from aluminum leads not only to weight savings but also to a high elasticity of the conveyor belt with a high load capacity at the same time.
the drive roller and the deflection roller of the conveyor belt have a small diameter, for example a diameter of 8 to 15 cm.
the conveyor belt of the conveyor belt is made of PVC fabric tape.
the PVC fabric belt is flexible, can also be used advantageously with smaller diameters of the drive and deflection roller of the conveyor belt and can withstand high loads.
Optimal dropping of milled material onto the conveyor belt is shown when the conveyor belt is at a distance of no more than 40 mm from the milling wheel in the working position of the milling system.
the conveyor belt has a hydraulic drive which is integrated into a hydraulic drive of the carrier vehicle.
the conveyor belt drive can be connected via a hydraulic connection can be supplied directly from the carrier vehicle with hydraulic fluid under the appropriate pressure.
the conveying speed of the conveyor belt can be regulated, for example, with a hydraulic valve controlled electronically from the driver's cab of the carrier vehicle.
a driver of the carrier vehicle can control the conveying speed of the conveyor belt while the milling system is in operation, for example via an electronic speed controller. This also regulates the ejection distance and the ejection quantity and determines the ejection location.
