Definitions

  • the invention relates to a cultivation compressor, which can be coupled to an excavator, with a hydraulically actuated unbalance generator.
  • Hydraulic add-on compactors are becoming increasingly popular as excavator attachments, especially in trench and pipeline construction. In conjunction with quick-change devices and turrets, they provide a cost-effective removable device considerable potential for cost savings and to increase occupational safety, because the residence of people to compaction work in trenches and pits can be omitted. Decisive factors in the use of vibration compacting devices are the excitation force and the working frequency.
  • Hydraulic excavator driven compactor plates can cover a wide speed / frequency range while motor driven ones rely on the limited working range of the motor. Hydraulically driven by the excavator plates are thus used for a variety of soil structures. For a grain spectrum up to 20 mm grain size, the speed range between 50 and 100 Hz is the optimum range. Inevitably, however, the exciter force increases or decreases with the square of the rotational speed. Too high forces in the pipe area are unfavorable, as they occur due to destructions or changes in position. In built-up areas, a high level of excitement is also often a disadvantage, as severe vibrations can cause damage to buildings. On the other hand, lower frequencies are favorable for coarse grains or cohesive soils, but this also reduces the excitation force and thus the possible installation depth.
  • the object of the present invention is to provide a cultivation compressor with which the excitation force can be adjusted and / or changed in a simple manner.
  • this object is achieved in a surprisingly simple and effective manner in that the unbalance generator has a drive shaft and at least two unbalance elements which occupy different positions relative to one another in dependence on the direction of rotation of the drive shaft.
  • a cultivation compressor has been realized in which the area of use of the compressor can be changed or halved mechanically in a simple manner.
  • a solution for reducing imbalance mass was developed with the aid of a multi-mass system.
  • the imbalance mass is driven by the hydraulics of the excavator.
  • the direction of rotation is changed by reversing the hydraulic direction.
  • the reversal of the flow direction of the hydraulic fluid is preferably controlled by a scissor hydraulics of the excavator.
  • At least a first unbalance element is arranged non-rotatably eccentrically on the drive shaft and at least a second unbalance element with respect to the drive shaft, in particular on the drive shaft, at least in a predetermined angular range is movable.
  • the at least one first unbalance element is permanently fixed in its position relative to the drive shaft, while the second unbalance element can change its position depending on the direction of rotation of the drive shaft and thus can assume different positions with respect to the drive shaft and thus in relation to the first unbalance element.
  • the second unbalance element is thus at least between two basic positions with respect to the drive shaft rotatably arranged. Preferably, it is mounted on the drive shaft. This allows the imbalance mass change.
  • At least one driver for mutual positional fixing of the at least two unbalance elements is provided.
  • the driver may be provided either on a non-rotatable unbalance element or on the movable relative to the drive shaft unbalance element.
  • three unbalance elements may be provided, wherein a relative to the drive shaft rotatable, in particular rotatably mounted on the drive shaft unbalance element is arranged axially between two non-rotatably mounted on the drive shaft unbalance elements.
  • the unbalance elements which are arranged axially adjacent to the rotatable imbalance element, preferably have the same mass.
  • the unbalance elements can be composed of different elements. It is also conceivable, a plurality of first and second unbalance elements, d. H. non-rotatably connected to the drive shaft unbalance elements and with respect to the drive shaft movable unbalance elements, alternately axially adjacent to each other.
  • the imbalance elements are of substantially identical construction, in particular substantially have the same mass, but by varying the mass distribution, the imbalance can be adapted to the conditions of use. As a result, the production cost of the imbalance elements can be reduced, since only one kind of imbalance element has to be produced.
  • the at least one with respect to the or on the drive shaft rotatably arranged imbalance element from a first position by about 180 ° in a second position is movable, the center of gravity position relative to the rotationally fixed unbalance elements is changed and As a result, the mass fraction of the rotationally movable imbalance element (compensating mass) compensated in the non-rotatably arranged imbalance elements.
  • At least one flow control valve is provided for controlling the hydraulic flow.
  • a flow control valve is provided for each hydraulic flow direction. Since different excavators have different sizes and hydraulic settings, different hydraulic flows are to be expected from excavator to excavator. This would mean that with different excavators different frequencies of the unbalance generator would be achieved with the same exciter mass, which makes targeted compacting difficult.
  • the unbalance generator supplied amount of hydraulic, z. B. constant 140I / min are determined, for example, although one excavator a volume flow of 170 l / min and another excavator generates a flow rate of 190 l / min. As a result, a frequency can be specified.
  • a hydraulic flow control valve is interposed in both hydraulic directions to obtain a constant hydraulic flow.
  • the hydraulic flow can be adjusted particularly easily if the flow control valve or valves are adjustable.
  • the volume flows of hydraulically driven by excavator compressor plates are adjustable.
  • this measure can cover a broad speed / frequency range.
  • a cultivation compressor 1 which comprises an unbalance generator 2.
  • the unbalance generator 2 is driven by a hydraulic motor 3, which is connected to the hydraulic system of an excavator, not shown.
  • a compressor plate 4 is set in motion.
  • the compressor plate 4 is connected via connecting elements 5 and buffer devices 6, in particular metal rubber buffer, with an upper part 7 of the add-on compactor 1.
  • the cultivation compressor 1 can be fastened via a receptacle 8 to an excavator arm 9.
  • the receptacle 8 can be designed as a quick-change system. As a result, a mechanical and hydraulic connection to the excavator can be made in a simple manner.
  • a rotary motor 10 connects, via which the attachment compressor 1 with respect to the excavator 9 can be rotated.
  • flow control valves 12 are connected, via which the volume flow, which passes from the excavator to the hydraulic motor 3, can be adjusted.
  • the flow direction of the hydraulic flow to the hydraulic motor 3 is reversible.
  • the unbalance generator 2 comprises two first unbalance elements 2.1, 2.2, which are non-rotatably connected to the drive shaft 20.
  • the unbalance elements 2.1, 2.2 are arranged eccentrically on the drive shaft 20.
  • An unbalanced element 2.3 designed identical with the unbalance elements 2.1, 2.2 is arranged axially between the unbalance elements 2.1, 2.2. It is also arranged on the drive shaft 20 and lies in the direction of rotation according to arrow 21 congruent between the imbalance elements 2.1, 2.2. In this position, the unbalance element 2.3 is held by a driver 22.
  • the unbalance generator 2 is shown with a different position of the unbalance element 2.3.
  • the unbalance element 2.3 is rotatably mounted on the drive shaft 20. Due to its inertia, it remains in a reversal of direction according to arrow 24 thus initially in its position while the imbalance elements 2.1, 2.2 are deflected. After a rotation of the drive shaft of about 180 °, the driver 22, depending on whether it is attached to the unbalance elements 2.1, 2.2 or the unbalance element 2.3, to the unbalance element 2.3 or the unbalance elements 2.1, 2.2 at.
  • the unbalance element 2.3 is fixed in position in a position pivoted about 180 ° with respect to the unbalance elements 2.1, 2.2.
  • the mass of the unbalance element 2.3 represents a compensation mass and the imbalance mass is reduced by the mass component of the unbalance element 2.3.
  • the excitation mass or unbalanced mass is divided into at least three parts in proportion to the mass reduction, wherein a preferably middle part (unbalance element 2.3) - the compensation mass - on the common drive shaft 20 is freely rotatable at least within limits and has a driver 22 formed as a driving pin.
  • the compensation mass (unbalance element 2.3) by the adjacent driving pin in the same oriented center of gravity as the unbalance elements 2.1, 2.2 taken.
  • the total mass therefore becomes effective in one direction with full excitation force.
