Definitions
- This invention relates to an implement for attachment to a vehicle. More specifically, this invention relates to a hydraulic circuit to control the implement.
- Agricultural vehicles such as a tractor, may be equipped or operated with various implements such as a front loader, or a trailed or mounted implement.
- Front loaders have a boom to which a tool is attached.
- the tool can be moved by a first pair of hydraulic cylinders on the loader.
- the boom is moved in a generally vertical direction by a second pair of hydraulic cylinders on the loader.
- the hydraulic cylinders are connected to two hydraulic circuits on the vehicle by hydraulic control valves.
- the control valves are connected to a driver control system in the tractor cab.
- An example of a tool attachable to a front loader is a standard bucket for transporting bulk material.
- the first pair of cylinders pivot the bucket and the second pair of cylinders raise and lower the bucket.
- Further hydraulic circuits may be connected to the first and second hydraulic circuits to operate other consumers on the front loader. It is usual to provide one or more further hydraulic circuit to control additional consumers related to the tools on the front loader. Tools requiring a further circuit to move a part associated with the tool are, for example:
- -A grab bucket provided with forks which can be raised and lowered relative to the bucket to tear silage out of a silage silo during loading.
- a further hydraulic circuit would raise and lower the forks.
- a front loader may be provided with a bucket having a pivotable beater attached.
- the further hydraulic circuit controls pivotal movement of the beater support relative to the bucket body whilst yet a further circuit controls the rotary drive of the beater.
- This tool loosens compacted silage during loading prior to distribution as animal fodder.
- the two hydraulic control valves may also be connected to external consumers when a front loader is not being used.
- the valves may be connected to a front and/or rear three-point linkage, to consumers on a trailed or mounted implement or, they may be connected to consumers on an implement connected to the tractor by a ball type hitch. As these external consumers are connected to the tractor by coupling means, the connections with the control valves are blocked when no trailed or mounted implement is attached to the tractor.
- trailed or mounted implements may also have further hydraulic circuits connected to a first and/or second hydraulic circuit.
- a sprayer may have a first hydraulic circuit to pivot the sprayer boom when driving along an inclined surface, a second hydraulic circuit to control the lifting and lowering of the sprayer boom in a vertical direction, a further hydraulic circuit to fold a first section of the sprayer boom during transit and yet a further circuit to fold a second section of the sprayer boom during transit.
- control valves which control the first and second circuits and are therefore operated with the same fluid flow as the first and second hydraulic circuits. This is far from ideal since different consumers require different fluid flows. As a consequence, the settings for the control valves have to be changed depending on whether a front loader, or a trailed or mounted implement or any other consumer in use. This can be easily forgotten by the driver resulting in consumers being operated incorrectly.
- fluid flow it is meant the fluid flow rate, that it the volume of fluid flowing through the circuit per unit time and also the amount of time the fluid is flowing through the circuit.
- control valves require further driver control systems such as buttons, or levers which take up space on the vehicle and increase the likelihood of driver error in operating the intended hydraulic circuit.
- control means to operate an implement is incorporated within the control system to operate other functions on the vehicle. It is an aim of the present invention to provide an implement attachable to a vehicle having a first hydraulic circuit which is connected to at least one further hydraulic circuit, each circuit having a fluid flow which may be different from each other and which can be regulated by the same control means on the vehicle.
- an implement as claimed in claim 1.
- Preferred features of the invention are set out in the dependent claims.
- An implement according to the invention means that further hydraulic circuits can be controlled from the same control means which control a first hydraulic circuit. This means that no additional or different control means for operating a front loader, for example are required. This allows for the simple exchange of a front loader between different tractors. In case of a trailed or mounted implement costs can be saved because the control valves on the vehicle are also used to control the further circuits on the implement.
- Figure 1 is a side view of a tractor provided with a front loader
- FIG. 2 is a hydraulic circuit diagram of an implement attached to a vehicle in accordance with the invention.
- Figure 1 shows a tractor 1 which has a front loader 2.
- the front loader comprises a boom 4 which carries a tool 6.
- a first pair of hydraulic cylinders 5 moves a tool 6, for example a bucket so that it pivots about a substantially horizontal axis.
- a second pair of hydraulic cylinders 3 lift and lower the boom 4.
- Figure 2 shows a circuit diagram of the hydraulic circuits on the front loader when they are connected to the tractor's hydraulic circuit.
- the dashed line shows which parts are located on the tractor 1 and which parts are located on the front loader 2.
- the hydraulic cylinders 3, 5 are connected by a multicoupler 7 to two control valves CV1 and CV2 on the tractor.
- the control valves CV1 and CV2 are connected to a pump 23 and a fluid reserve 22 on the tractor.
- the control valves CV1 , CV2 are connected to a tractor control unit 18 which is connected to a control means 10 and a terminal 20 in the tractor cab as shown by the dotted lines.
- the front loader may also be provided with its own control unit 26a which communicates with the tractor control unit 18.
- the control means 10 comprises a lever 11 with selector means 13,14, 24 and 25.
- Lever 11 is a cross gate lever which can be moved in four directions (forwards and backwards along axis A and left and right along axis B) about a central, neutral position.
- Selector means 13, 14 may be, for example buttons or switches which can be activated whilst the driver moves lever 1 1.
- Selector means 24, 25 are provided on the base of the control means 10.
- Terminal 20 displays various parameters associated with the tractor and front loader and allows various parameters, associated with the hydraulic circuits, such as fluid flow to be set.
- a first hydraulic circuit HC1 is connected to control valve CV1.
- the first hydraulic circuit HC1 comprises a first cylinder or first pair of cylinders 5.
- First cylinder 5 is used to move a tool attached to the front loader such as a bucket, or hay grab.
- a further consumer 8 such as a hydraulic cylinder on a trailed or mounted implement connected to the rear of the tractor may alternatively be connected to hydraulic circuit HC1 when the front loader is not being used.
- Consumer 8 is connected to circuit HC1 by circuit 8a. Since circuit 8a is only controlled by valve CV1 the fluid flow through it can only be changed if the fluid flow through circuit HC1 is changed.
- fluid flow it is meant the volume flow rate, that it the volume of fluid flowing through the circuit per unit time and also the amount of time the fluid is flowing through the circuit. The latter is controlled by how long an associated circuit valve is activated.
- first hydraulic circuit HC1 is connected to at least one further hydraulic circuit HC2 or HC3 by respective switch means, switch valves SV1 , SV2. These switch valves are connected to the tractor control unit 18 and front loader control unit 26a if present. Switch valves SV1 , SV2 may be integrated into one single valve.
- FIG 2 two further hydraulic circuits are shown, a second further hydraulic circuit HC2 and a third further hydraulic circuit HC3.
- Each further circuit HC2, HC3 is connected to HC1 circuit by respective switch valves SV1 and SV2.
- Circuits HC2 and HC3 are connected to consumers 16 and 17 respectively which may be needed, for example to control a grab bucket, or a bucket with a pivotable beater as described above. Further circuits could be connected to HC1 by further switch means.
- a fourth further hydraulic circuit HC4 is connected to a consumer or hydraulic cylinder 19 in parallel to first hydraulic circuit HC1.
- Circuit HC4 is provided with a switch valve SV3 which is connected to the control unit 18 and front loader control unit 26a if it is present.
- the hydraulic circuit HC4 may be used, for example to control an automatic locking means for connecting the boom 4 to the tool 6 to make attachment of the tool to the boom easy.
- cross gate lever 11 When it is desired to move a tool by pressurising or de-pressurising cylinder 5, cross gate lever 11 is moved to the left and right as indicated by arrows B. In this position switch valves SV1 and SV2 are in a position so that fluid flows from and to the fluid reserve 22 to cylinder 5 and switch valve SV3 is closed.
- selector means 13 on lever 11 which controls switch valve SV1 is pushed and cross gate lever moves left and right in the direction of arrows B. In this instance fluid flows to and from the fluid reserve 22 to consumer 16.
- selector means 14 When it is desired to activate consumer 17, selector means 14 is pushed which controls SV2 and the cross gate lever is moved in the direction of arrows B.
- Consumer 8 and 9 are only used/supplied when the front loader is hydraulically disconnected from the supply system. These consumers 8,9 are, controlled by the settings of CV1 and CV2 respectively.
- control valve CV1 can be entered into the terminal 20 for each of the circuits HC1 , HC2, HC3 and HC4 which therefore affects the fluid flow through each circuit.
- the length of time switch valves SV1, SV2 and SV3 are activated for each circuit, as well as the volume flow rate of the fluid through each circuit can be set. For example, when selector means 13 is pressed on control means 10, control valve CV1 automatically moves to the set position at the same time as switch valve SV1 is switched. The same occurs for circuits HC3 and HC4 and switches SV2 and SV3 when the respective selector means 14 and 25 are pressed on control means 10. This means that each circuit HC1 , HC2, HC3 and HC4 can have its own fluid flow independent of the other circuits.
- the invention means that various hydraulic circuits associated with the front loader, or another implement attached to a vehicle can be controlled by the same control means in the vehicle and each circuit can be operated with its own fluid flow parameters suitable for the consumer concerned.
- An additional hydraulic circuit HC5 on the front loader comprises a hydraulic cylinder or pair of cylinders 3 connected to a second control valve CV2 on the tractor by a multicoupler 7. Hydraulic cylinder 3 is used to lift and lower the boom of the front loader.
- a further consumer 9 such as a hydraulic cylinder on a trailed or mounted implement connected to the rear of the tractor may be alternatively connected to the hydraulic circuit HC5.
- Consumer 9 is connected to circuit HC5 by hydraulic circuit 9a.
- the fluid flow through HC5 is regulated by control valve CV2 which is controlled by control means 10 located in the tractor cab. Since circuit 9a is only controlled by valve CV2 the fluid flow through it can only be changed if the flow rate through further hydraulic circuit HC2 is changed.
- CV2 is connected to control unit 18 which is connected to control means 10 located in the tractor cab.
- Settings for control valve CV2 can be entered into the terminal for hydraulic circuit HC5.
- cross gate lever 1 1 is moved forwards or backwards as indicated by arrows A.
- a damping circuit 21 with valve 21a is connected to additional hydraulic circuit HC5 and controlled by control means 10 by pressing selector means 24.
- the damping circuit provides damping to the front loader when moving over rough ground.
- Damping circuit 21 is also connected to the tractor control unit 18 and the front loader control unit 26a if present.
- the further hydraulic circuits HC2, HC3 and HC4 are connected to the first hydraulic circuit HC1 whilst additional hydraulic circuit HC5 is only connected to circuit 9a.
- additional circuit HC5 is connected instead to the further hydraulic circuits HC2, HC3 and HC4 with switch valves without leaving the scope of the invention.
- the invention may be applicable to any vehicle (not just a tractor) which can carry an implement and/or tool.
