Description

Agricultural machine with a fluid supplying device and fluid supplying method
1. FIELD OF THE INVENTION
The invention refers to an agricultural machine with several parts to be supplied with a fluid and to a method for supplying these parts with the fluid.
2. BACKGROUND OF THE INVENTION
In an agricultural machine often the requirement occurs that several rotating or otherwise moving parts of the agricultural machine need to be supplied with a fluid. The fluid is provided in one source and needs to be distributed onto the plurality of parts. One example is that several parts of the agricultural machine must permanently be greased, e.g. supplied with greasing material, and the agricultural machine comprises one source for the greasing material.
The invention can be used in an agricultural or stationary baler. A bale forming apparatus (baler) forms under pressure cylindrical or cuboid bales from loose crop or recycling material. The bale forming apparatus may be a stationary plant or a part of a vehicle which is moved over ground. The moved bale forming apparatus picks up crop material from the ground. Several parts on board of the vehicle or the stationary plant must permanently be provided with greasing material while the bale forming apparatus is operated. The greasing material must automatically be provided to the parts.
Several fluid supplying devices for further purposes have been disclosed. US 6,932,112 B2 discloses a multiple port valve 10 for distributing a fluid. The multiple port valve 10 comprises several outlet ports 12, cf. Fig. 1. A first valve body member 14 and a second valve body member 16 together surround an internal cavity 18, cf. Fig. 4. A rotational disk 20 with one aperture 22 directs the fluid to at least one outlet port 12. The fluid flows from an inlet port 28 in the first valve body member 14 into a distribution chamber 30 adjacent to the disk 20. A drive shaft 52 rotates the disk 20 with the aperture 22. In one embodiment several apertures 22 are arranged in the disk 20 to align with several outlets ports 12. The shaft 52 rotates the disk 20 until an aperture 22 is aligned with a selected output port 12. In one embodiment an electric stepper motor 56 is coupled with the disk 20 through a gearbox 58. A sensor 64 senses the current position of the aperture 22. The aperture 22 is positioned proximate to the selected output port 12. EP 2177756 A2 discloses a greasing system for greasing different lubrication points (Schmierstellen 14) in a wind energy plant (Windkraftanlage 10). A feeding device (Schmiermittelfördereinrichtung 4) conveys lubricant (Schmiermittel) from a reservoir (Schmiermittelreservoir 3) through a feeding line (Schmiermittelzuführung 5) to a rotating aperture (Drehdurchführung 20), Fig. 2. The aperture 20 is connected with the shaft (Rotorwelle 17) which is rotated by the blades of the wind turbine. The aperture 20 rotates together with the shaft 17. A channel (Durchführungskanal 21) is arranged in the interior of the shaft 17. This channel 21 guides the lubricant from the aperture 20 through the shaft 17 towards several rotating lubrication points 14. In one embodiment a progressive distributor (Progressiv-Verteiler 31) distributes lubricant onto different lines 5, cf. Fig. 4.
3. SUMMARY OF THE INVENTION A problem solved by the invention is to provide an agricultural machine with a plurality of parts to be supplied with a fluid wherein a fluid supplying device only requires one fluid inlet, operates in a reliable manner, and can be implemented in an easy way. A further problem is to provide a method for supplying the plurality of parts with fluid by using such a fluid supplying device.
This problem is solved by an agricultural machine with the features of claim 1 and by a supplying method with the features of claim 12. Preferred embodiments are specified in the depending claims.
The agricultural machine according to the invention comprises a plurality of parts. A fluid supplying device supplies this plurality of parts with a fluid. The term “fluid” refers to every kind of liquid or gas.
The fluid supplying device according to the invention comprises - at least one fluid inlet, - a plurality of fluid outlets, - a housing which defines a buffering cavity, - a distributing member, and - a drive for the distributing member.
The distributing member is positioned between the buffering cavity and the plurality of fluid outlets. The distributing member is mounted such that the distributing member can be rotated with respect to the plurality of fluid outlets. The drive permanently rotates the distributing member with respect to the plurality of fluid outlets. A distributing aperture is cut into the distributing member. In every rotational position of the distributing member with respect to the plurality of outlets the distributing aperture overlaps with at least one fluid outlet. Therefore the distributing aperture in the rotated distributing member overlaps at every time point during operation with at least one fluid outlet.
The fluid inlet is in fluid communication with the buffering cavity such that fluid can flow through the fluid inlet into the buffering cavity. The distributing aperture and at least one fluid outlet overlapping with the distributing aperture provide a fluid communication between the buffering cavity and this overlapping fluid outlet. Thereby fluid can flow from the buffering cavity into this fluid outlet. This fluid outlet is in fluid communication with at least one part of the plurality. Therefore the fluid can flow from the buffering cavity to this part of the plurality.
The fluid supplying device operates as follows: - The drive permanently rotates the distributing member. - The fluid is conveyed from the fluid inlet to the buffering cavity. - The fluid is further conveyed through the distributing aperture and the at least one fluid outlet currently overlapping with the distributing aperture. - The fluid is further conveyed through this fluid outlet to at least one part of the machine.
4. ADVANTAGES
The fluid supplying device and the fluid supplying method according to the invention ensure that every part of the plurality is periodically supplied with the fluid. The dimensions of the fluid outlets and of the distributing aperture can be adapted to ensure that every part obtains enough fluid. Only one fluid inlet and therefore only one reservoir and one input line guiding to this fluid inlet is required for supplying several parts of the agricultural machine with fluid. The reservoir can be positioned at a position where a human operator can easily add fluid to the reservoir - regardless of the positions of the parts to be supplied with the fluid.
For ensuring that every part obtains enough fluid no sensor is required, in particular no sensor which measures the current rotational position of the distributing member with respect to the fluid outlets or the position of the distributing aperture with respect to the plurality of fluid outlets. In addition no control unit for controlling or steering the operation of the fluid supplying device is required. Such a control unit would be necessary if a sensor were required or if the distributing member needed to be positioned with respect to the plurality of fluid outlets.
According to the invention the drive permanently rotates the distributing member with the distributing aperture. Therefore no start-stop operation is performed. A permanent rotation applies less mechanical stress onto the drive and onto the rotated distributing member compared with a start-stop operation.
Rotating the distributing member in a permanent manner requires less kinetic energy and less mechanical or electric power than a start-stop rotation or an alternative way of moving the distributing member.
Thanks to the invention a fluid communication between the buffering cavity and at least one fluid outlet is provided in every rotational position of the distributing member. Therefore an output port for the buffering cavity is provided in every rotational position. This ensures that it is possible to guide permanently fluid into the buffering cavity without the risk of an overload or of congestion due to a high amount of fluid. No sensor is required which monitors whether or not an output port for the buffering cavity is actually provided if needed. No valve or further element for opening or closing the fluid inlet is required. Therefore the invention saves a movable mechanical element assigned to the fluid inlet. In addition no sensor for measuring the amount per time of fluid guided through the fluid inlet into the buffering cavity is required. Therefore the buffering cavity does only require little space. The housing can be a small object.
Thanks to the invention the distributing member is the only part of the fluid supplying device which needs to be moved. All further parts of the fluid supplying device can be stationary parts and can be fixed. Therefore the fluid supplying device is subjected to less mechanical stress. A motor for rotating the distributing member needs only to provide few rotational power and can be arranged outside of the housing.
5. PREFERED EMBODIMENTS
Preferably the drive rotates the distributing member with constant velocity in the same rotating direction. This embodiment saves the need to accelerate and to decelerate the distributing member. Only the frictional force has to be surpassed. This embodiment therefore requires even less energy.
It is also possible, however, that the rotating velocity is changed during operation, e.g. depending on a measured rotating velocity of a part to be supplied with fluid or depending on a measured load applied onto a part of the agricultural machine to be supplied with the fluid.
According to the invention the distributing member is rotatably mounted. Therefore the distributing member can be rotated around a rotating axis. The fluid outlets of the plurality are preferably arranged around this rotating axis. In one embodiment every fluid outlet has the same distance to this rotating axis.
According to the invention the distributing aperture overlaps with at least one fluid outlet in every rotational position of the distributing member. The overlapping apertures form an opening and provide a fluid communication between the buffering cavity and at least one fluid outlet. In one embodiment the fluid communication provided by the distributing aperture and the respective at least overlapping fluid outlet has the same cross-sectional area in every rotational position of the distributing member. As a consequence the cross-sectional area remains constant over time while the distributing member is rotated - regardless of the rotating velocity.
Thanks to this embodiment the provided fluid communication enables the same throughput of fluid in every rotational position. Therefore a constant throughput of fluid out of the buffering cavity is achieved while the drive rotates the distributing member. A constant amount per time of fluid can be injected into the buffering cavity without the risk of an overflow or of a lack of fluid. No sensor for the amount of fluid in the buffering cavity is required. This embodiment enables a very small housing for the buffering cavity. The buffering cavity is only needed for buffering fluid due to operating tolerances and inevitable variances in the fluid flow or if one part to be supplied currently consumes a smaller amount of fluid than usual.
In one implementation this embodiment with the constant cross-sectional area is achieved by the following feature: In every rotational position or in at least in one rotational position of the distributing member the or at least one distributing aperture simultaneously overlaps with at least two fluid outlets. The distributing aperture may in every rotational position either overlap with exactly one fluid outlet or simultaneously with two adjacent fluid outlets.
In one implementation the feature of the constant cross-section area is achieved by a kidney-shaped distributing aperture which extends arcuate around the rotating axis. The two ends of the kidney can simultaneously overlap with two fluid outlets. The kidney-shaped distributing aperture can also be used if no constant cross-section area is achieved.
In one embodiment the fluid outlets are cut into a receiving member. This receiving member is fixed with respect to the housing, e.g. rigidly connected with the housing. The housing and the receiving member are therefore stationary parts and are not moved during operation. This embodiment leads to a robust mechanical construction.
In one embodiment the distributing member comprises a distributing plate and a shaft. The buffering cavity can be positioned around the shaft. The distributing plate is rigidly mounted on the shaft and extends in a plane perpendicular to the shaft. The or every distributing aperture is cut into the distributing plate. The drive for the distributing member rotates the shaft. This embodiment makes it even easier to position the drive at a preferred location spaced apart from the buffering cavity. Preferably the distributing plate has the shape of a disk but further shapes are also possible.
In one implementation the fluid outlets are cut into a receiving plate belonging to the receiving member. This receiving plate is parallel to the rotated distributing plate. These two plates can be situated closed to each other such a rotation-enabling cavity occurs between these two plates and enables a rotation of the distributing plate with respect to the receiving plate. It is easy to provide a sealing for this rotation-enabling cavity such that fluid can only leave the distributing-enabling cavity through a fluid outlet.
In one embodiment the supplying device comprises a motor which rotates the distributing member and no further device. This motor can be an electric or hydraulic motor, e.g. The distributing member is rotated regardless of the current operating state of the further devices. The motor only needs to provide little rotational power. In one implementation a battery provides electric energy to this motor.
In an alternative embodiment a drive which drives a further device of the agricultural machine is additionally used for rotating the distributing member via a suitable transmission element. This embodiment saves an own drive especially for the distributing member.
Preferably the buffering cavity comprises only one outlet, namely the at least one distributing aperture in the rotating distributing member overlapping with at least one fluid outlet. Fluid from the input line can only enter the buffering cavity through the inlet and can leave the buffering cavity only through the distributing aperture being in an overlapping position with at least one fluid outlet.
In one embodiment two parallel input lines can guide fluid to the buffering cavity. This embodiment ensures that fluid is guided to the buffering cavity even if one input line is blocked or broken. In one implementation two fluid reservoirs are connected with the two input lines. If one reservoir is empty, fluid can still be guided to the buffering cavity from the other reservoir.
In one implementation the fluid which is to be distributed is greasing material (a greasing or lubrication fluid). The parts of the plurality are permanently be greased by the supplying device and method according to the invention. In a further embodiment the fluid is a cooling fluid, e.g. cooling air or a cooling liquid. The fluid can also serve as a dissolver.
In one implementation the plurality of parts to be supplied are arranged on board of a vehicle, e.g. of an agricultural harvester. The harvester can be a bale forming apparatus, a loader wagon, a mowing machine, a combine harvester, or a field chopper, e.g. The agricultural machine can also distribute seed corns or fertilizer material or a further fluid over ground. A reservoir for fluid and the fluid supplying device according to the invention are also arranged on board of this vehicle.
These and other aspects of the invention and of the preferred embodiment will be even more apparent from the detailed embodiment as described below and will be elucidated in detail there.

7. DETAILED DESCRIPTION OF EMBODIMENT
In the embodiment the invention is used in a round baler which serves as the agricultural machine. This round baler picks up loose crop material from the ground, conveys the crop material into a drum-shaped bale forming chamber, forms under pressure a round-cylindrical bale in the bale forming chamber from the injected loose crop material, wraps the formed bale in the bale forming chamber, and ejects the wrapped bale.
The baler is pulled by a tractor or field chopper or combine harvester in the travelling direction TD.
The baler comprises the following parts, cf. Fig. 1: - a towing unit 27, - a pick-up unit 21 with several spring-mounted tines 22.1, 22.2, ..., - a conveying rotor 24 with several rigid tines which engage from above into a feeding channel, - several pressing belts 30 which surround a bale forming chamber, - an inner left tensioning arm 32.1 and a corresponding right inner tensioning arm (not shown), - an outer left tensioning arm 32.2 and a corresponding right outer tensioning arm (not shown) rigidly connected with the inner tensioning arms, - a front housing 59, - a pivotal tailgate 43 mounted at the outer tensioning arms 32.2, - several stationary guiding and deflecting rollers 26.1, 26.2, ... rotatably mounted at the tailgate 43, - several stationary guiding and deflecting rollers 29.1, 29.2 rotatably mounted at the front housing 59, - several movable guiding and deflecting rollers 23.1, 23.2, ... rotatably mounted between the left inner tensioning arm 32.1 and the corresponding right inner tensioning arm, - a left piston-cylinder device 34 which is connected with the tailgate 43 in a lower pivoting axis 35 and with the left outer tensioning arm 32.2 in the upper pivoting axis 33, - a corresponding right piston-cylinder device (not shown) which is connected with the tailgate 43 in a lower pivoting axis 35 and with the right outer tensioning arm 32.2 in the upper pivoting axis 33, - two starter rollers 28.1, 28.2 which form the two borders of the crop material inlet, - a left cover 37 and a corresponding right cover (not shown), - a wrapping material feeding roller 39 arranged adjacent to the wrapping material inlet below the deflecting roller 29.3, - a wrapping material reel 40, - a pivotal ramp 50 for depositing a wrapped bale onto the ground, and - a greasing material supplying device comprising a fluid supplying device 4 according to the invention.
The pressing belts 30 surround a drum-shaped bale forming chamber. Fig. 1 shows a small bale B.1 on the two supporting rollers 28.1, 28.2 and a completed bale B. In reality a bale in the bale forming chamber first reaches the size B.1 and afterwards the size B.
The increasing bale B.1, B in the bale forming chamber applies an expanding pressure onto the pressing belts 30. The two tensioning arms 32.1, 32.2 are rigidly connected with each other and are pivotally mounted at the front housing 59. The expanding force of the increasing bale B.1, B pivots the tensioning arrangement 32.1, 32.2 against the force of a retaining device comprising the left piston-cylinder device 34 and the corresponding right piston-cylinder device.
Several rotatable or otherwise movable parts of the baler shown in Fig. 1 have permanently to be supplied with greasing material serving as the fluid, among them the following parts: - the pick-up unit 21, - the guiding and deflecting rollers 23.1, 23.2, ..., 26.1, 26.2, ... , 29.1, 29.2, - the common pivoting axle of the tensioning arms 32.1, 32.2, - the pivoting axes 33, 35 of the piston-cylinder devices 34, - the conveying rotor 24, - the starter rollers 28.1,28.2, - the wrapping material feeding roller 39, and - the pivotal ramp 50.
Fig. 2 shows schematically in a side view the greasing material supplying device comprising a fluid supplying device 4 according to the the invention. A pump 15 permanently presses greasing material from a reservoir 18 (only shown schematically) through the aperture 19.2 cut into the housing 1 into an input line 13. The reservoir 18 is positioned such that a human operator can easily add greasing material and can do this in an ergonomic manner. In one implementation a level sensor measures the current level of fluid in the reservoir 18. An alert is generated if the fluid level in the reservoir falls below a given threshold.
The input line 13 guides the greasing material through a further aperture 19.1 to a fluid supplying device 4 according to the invention.
One output line 14.1, 14.2 per baler part to be greased is provided and guides greasing material from the fluid supplying device 4 to the corresponding baler part. This output line 14.1, 14.2, ... begins in a receiving aperture 9.1, 9.2,... In a variation one output line 14.1, 14.2, ... supplies several baler parts with greasing material.
This fluid supplying device 4 comprises: - a tube-shaped stationary housing 1 surrounding a buffering cavity 10, - a driven shaft 2 positioned in the interior of the stationary housing 1 and guided through one housing wall, - two ball bearings 5, 6 guiding the driven shaft 2, - a rotating disk 3 rigidly connected with the shaft 2 with respect to the housing 1, - a stationary disk 7 rigidly connected with the housing 1 and being parallel to the rotating disk 3, - a rotation-enabling cavity 11 arranged between the rotating disk 3 and the stationary disk 7, - a sealing 8 for the rotation-enabling cavity 11.
The rotating disk 3 belongs to the rotated distributing member and comprises one rotating aperture 12 which is used as the distributing aperture in the distributing member. The rotating disk 3 can be rotated around a rotating axis 16 which equals the center axis of the driven shaft 2. The rotating aperture 12 of the embodiment has the shape of a kidney or of a segment of a torus being arcuate around the rotating axis 16. The rotating aperture 12 extends in a circle segment, preferably of 20 degrees to 40 degrees, around this rotating axis 16.
The stationary disk 7 serves as the receiving member and comprises one stationary aperture 9.1, 9.2 per output line 14.1, 14.2. Every stationary aperture 9.1, 9.2 serves as a receiving aperture in the receiving member 7. Every output line 14.n begins in the corresponding stationary aperture 9.n and guides greasing material to the or every assigned baler part to be greased (n=1,2,3,...). The center axis of the stationary disk 7 coincides with the rotating axis 16 of the rotating disk 3. The stationary disk 7 is rigidly connected with the stationary housing 1. The stationary apertures 9.1, 9.2 are arranged around the rotating axis 16, preferably all with the same distance to the rotating axis 16. The stationary housing 1 prevents greasing material from leaving the buffering cavity 10 outside of the rotating aperture 12. A motor 17 (only shown schematically) permanently rotates the shaft 2 around the rotating axis 16, preferably with constant velocity. The shaft 2 is driven by the motor 17 via a chain and/or a sprocket wheel or directly in the case of an electrical motor, e.g. The two ball bearings 5, 6 enable the shaft 2 to rotate with low friction with respect to the stationary housing 1. Rotating the shaft 2 makes the disk 3 continuously rotating around the rotating axis 16. The rotating aperture 12 permanently rotates around the rotating axis 16.
In one implementation the motor 17 is an electric motor which is only used for continuously rotating the shaft 2. Thereby the shaft 2 is permanently rotated - regardless whether or not the baler parts to be supplied with the fluid are rotated or not. In an alternative implementation a baler part to be greased is rotated and rotates the shaft 2, e.g. via a chain drive. This alternative embodiment saves an own motor for the shaft 2.
The sealing 8 surrounds the rotation-enabling cavity 11 between the two disks 3, 7 and prevents greasing material from radially leaving the rotationenabling cavity 11. Greasing material can only enter the rotation-enabling cavity 11 through the rotating aperture 12 and can only leave it through the stationary apertures 9.1, 9.2.
The rotating disk 3 on the shaft 2 is permanently rotated around the rotating axis 16. The rotating aperture 12 is therefore permanently rotated around this rotating axis 16. The rotating aperture 12 comes subsequently in an overlapping position with every stationary aperture 9.1, 9.2. “Overlapping” is a relative position of two apertures seen in a viewing direction parallel to the rotating axis 16 in which an opening reaching through both apertures occurs. In the embodiment the rotating aperture 12 extends along such a large segment of a circle around the axis 16 that in every rotational position of the rotating disk 3 and therefore at every time point the rotating aperture 12 overlaps with at least one stationary aperture 9.1, 9.2. Either the rotating aperture 12 fully overlaps with one stationary aperture 9.1, 9.2 (the entire stationary aperture 9.1, 9.2 is opened) or partially overlaps with two adjacent stationary apertures 9.1, 9.2. Both situations occur subsequently. In the embodiment the shaft 2 and therefore the disk 3 are rotated with constant velocity. The overall aperture area remains approximately constant over time.
Fig. 3 shows the rotating disk 3 with the rotating aperture 12. Fig. 4 shows the stationary disk 7 with the stationary aperture 9.1, 9.2. The rotating axis 16 of the shaft 2 is in the plane of Fig. 2 and is perpendicular to the drawing planes of Fig. 3 and of Fig. 4.
In the embodiment the two disks 3, 7 are arranged in two planes both being perpendicular to the rotating axis 16 and to the drawing plane of Fig. 2. The distance between these two disks 3, 7 is so small and therefore the volume of the rotation-enabling cavity 11 is so small that the following effect is achieved: Greasing material can only pass the rotation-enabling cavity 11 through the rotating aperture 12 and the or every stationary aperture 9.1, 9.2 which currently overlaps with the rotating aperture 12. As the overlapping area, i.e. the throughput area, through the rotation-enabling cavity 11 remains constant over time, a constant flow of greasing material passes the rotation-enabling cavity 11. The amount of greasing material entering one specific output line 14.1, 14.2, ... through the assigned stationary aperture 9.1, 9.2 increases from zero to a maximum (partial increasing overlap with the rotating aperture 12), remains at the maximum value for a time period (full overlap remains) and afterwards decreases to zero (partial decreasing overlap).
In a variation a sensor measures an operating parameter of a moving part of the harvester, e.g. a rotating velocity or a torque or the consumption of electrical energy. The drive 17 rotates the shaft 2 with a velocity depending on a measured value of this parameter, e.g. rotates the shaft 2 quicker in case of a high measured rotating velocity or torque or energy consumption. Or the shaft 2 is mechanically connected with the rotated machine and is rotated with a velocity proportional to the machine velocity.
Reference signs used in the claims will not limit the scope of the claimed invention. The term “comprises” does not exclude other elements or steps. The articles “a”, “an”, and “one” do not exclude a plurality of elements. Features specified in several depending claims may be combined in an advantageous manner.
