Definitions

  • the present invention relates to high-pressure cleaning devices for use in soiled surroundings or enclosures such as pigsties.
  • Programmable devices or robots for carrying out cleansing operations for instance in large-scale agricultural plants or slaughterhouses are known within the art, which are able to move a nozzle section in a pre-programmed and complicated manner for instance throughout a row of enclosures, such as pigsties, and thereby performing complicated cleansing operations.
  • enclosures such as pigsties
  • the surroundings in which they operate must, however, be designed accordingly, allowing for instance a robot to move automatically from one enclosure to the next.
  • Unintended obstacles along the paths of movement of such robots are of course not allowed, and may even lead to hazardous situations.
  • Such devices may be unnecessarily complicated and hence expensive for use except in said large-scale plants, and they furthermore generally need to be supplied not only with the appropriate high-pressure fluid but also with electricity either via a direct connection to the AC mains supply or via built-in batteries.
  • a high-pressure cleaning device for use in soiled enclosures, which is able to provide a desired coverage with a high-pressure cleaning fluid of a surface area totally surrounding the device in one plane, for instance the horizontal plane hereof, and with a coverage region - or angle - in another plane, for instance the vertical plane, which may be chosen according to the specific needs.
  • the device is driven solely by means of the high-pressure fluid itself, i.e. the high-pressure fluid is used both for cleaning purposes and for attaining the necessary movements of parts of the device, such as a nozzle section, during the cleaning operation.
  • the high-pressure fluid is used both for cleaning purposes and for attaining the necessary movements of parts of the device, such as a nozzle section, during the cleaning operation.
  • a cleaning device in which at least one nozzle section for delivering high pressure cleaning fluid is provided with means for simultaneous movement in two dimensions in space, each of these means requiring only a supply of high pressure fluid to attain their movements and by which means cleaning fluid is provided to a region in space surrounding the cleaning device.
  • the cleaning fluid is provided to a region completely surrounding the device in the horizontal plane hereof, whereas the provision of cleaning fluid is restricted to a certain predetermined region in the vertical plane.
  • the cleaning fluid is provided to a region completely surrounding the device in the vertical plane hereof, whereas the provision of cleaning fluid is restricted to a certain predetermined region in the horizontal plane.
  • the movement of the nozzle section in the horizontal and vertical planes can either take place continuously in both planes or alternatively continuously in one plane and in a stepwise manner in the other.
  • a presently preferred embodiment of the invention comprising stepwise rotation of the nozzle section in the horizontal plane and simultaneous continuos pivotal movement within a predetermined vertical range is defined by claim 4.
  • the nozzle is rotated about a vertical axis in steps, and for each of these steps a vertical sweep of the nozzle is performed between predetermined elevation angles, i.e. angles relative to the horizontal plane.
  • the stepwise rotation about the vertical axis is continued over ⁇ and as a possibility beyond ⁇ a complete 360 degrees revolution in the horizontal plane with the effect that a complete cylindrical surface surrounding the device is being provided with cleansing fluid.
  • a possible alternative would be to move the nozzle section stepwise in the vertical plane and rotate it continuously in the horizontal plane.
  • FIG. 1 there is shown a schematic representation of an embodiment of the cleaning device according to the present invention.
  • the nozzle 8 delivering the cleansing fluid is moved in an oscillating manner continuously over a certain, predefined angular range in the vertical plane, whereas the horizontal movement around the longitudinal axis X takes place in a stepwise manner over and beyond the entire 360 degrees azimuth interval.
  • other modes of movement of the nozzle 8 would also fall within the general inventive concept, as defined by the independent claim 1.
  • the nozzle 8 is supported for oscillatory movement in the vertical plane, as indicated by the arrow B, on a pivot arm 23 via a pivot joint 24.
  • this joint 24 the vertical angle of the nozzle 8 relative to the pivot arm 23 can be adjusted, thereby determining the limits of the vertical coverage angle of the nozzle in accordance with the specific requirements during use of the device.
  • the pivot arm 23 is pivotally connected to a supporting arm 22 attached to the vertical column 3, such that the arm 23 can rotate in the horizontal direction.
  • the stepwise horizontal rotation is achieved by the application of a hydraulic gearmotor 4 carrying the column 3 and mounted on a stand 2 which may be provided with (not shown) wheels or rollers to facilitate transport of the device.
  • High-pressure fluid is entered via the inlet 9 for driving the gearmotor 4, whereupon the fluid leaves the gearmotor 4 at an outlet 10 hereof and passes through the column 3 via a pipeline 11.
  • the gearmotor 4 is provided with an actuator device 5 comprising an actuator arm 6.
  • an actuator device 5 comprising an actuator arm 6.
  • the gearmotor 4 is able to undergo a rotation by one azimuthal step in the direction of the arrow A, whereupon it remains in this position until the actuator arm 6 again resumes its lowermost position.
  • the gearmotor then rotates another azimuthal step and so on.
  • the pipeline 11 is terminated by a T-connection in which the flow of high-pressure fluid is split up into a portion delivered to the nozzle 8 via a suitable flexible connection, such as the hose 12 and a portion leaving the T-connection through the pipeline 13. This portion of the fluid is used to drive the vertical and horizontal movements of the device, as described below.
  • a flow switch 14 provided with two outlets a and b.
  • the switch 14 is provided with an arm 15 for directing the fluid to either one or the outer of the outlets a and b.
  • the outlet a is connected via a pipeline 18 to an upper inlet 29 of a hydraulic cylinder 21, whereas the outlet b is connected via a pipeline 17 to a lower inlet 30 of the hydraulic cylinder 21.
  • the cylinder 21 is pivotally attached to the column 3 and the distal end of the piston rod 27 from the piston in the cylinder is pivotally connected to the pivot arm 23.
  • a reciprocating movement of the piston of the hydraulic cylinder 21 is transformed to an oscillating movement of the arm 23 carrying the nozzle 8.
  • a connecting arm 19 passes between a point on the pivot arm 23 carrying the nozzle 8 and the actuator arm 6 of the gear motor 4.
  • the actuator arm 6 follows the oscillatory motion of the pivot arm 23, and whenever the pivot arm 23 is in its lowermost position, the gearmotor thus rotates one step in the direction of the arrow A.
  • the flow switch 14 switches between its two states, thereby directing the flow of fluid to either the outlet a or the outlet b, controlled by the movement of the connecting arm 19.
  • the flow switch actuator arm 15 is connected to a connecting member 20 on the connecting arm 19 by means of a tension member 16, for instance a helical spring. In this manner the switch acts as a bistable switch, which practically momentarily switches between its two states at the appropriate position of the connecting arm 19.
  • the rate of flow of fluid through the pipeline 13 is controlled by means of the valve 25 provided with a suitable adjustment means 26.
  • the speed of the oscillatory movement of the nozzle 8 and hence the rotational speed of the device around the longitudinal axis X through the vertical column 3 can be varied according to the specific needs.
  • FIG. 2 there is shown a schematic representation of the part of an alternative embodiment providing continuos rotational movement in the horizontal plane.
  • This mechanism is thus to be regarded as an alternative to the stepwise mechanism for horizontal rotation of the column 3 provided by the gearmotor 4 and associated controlling means according to the first embodiment described above.
  • the vertical column 3 of the cleaning device is provided with a chain wheel 31 connected for rotational movement to a second chain wheel 32 generally of a larger diameter by means of a chain 42.
  • a chain wheel mechanism as shown in Figure 2 could also be replaced by various mechanical equivalent means such as a tooth belt, a rack and pinion mechanism, direct engagement between two gear wheels etc. without departing from the scope of the invention.
  • the rotational movement of the larger diameter chain wheel 32 is attained by a pivotally mounted hydraulic cylinder 34, the piston rod 43 of which is connected to the larger diameter chain wheel 32 at a point 33.
  • the mechanism is driven by the high-pressure fluid entering at the inlet 37 to a flow switch 36, which directs the flow of fluid either to one end of the hydraulic cylinder 34 via a first fluid outlet 38 or to the other end of the cylinder via the other outlet 39 of the flow switch 36.
  • the flow switch 36 is controlled by an actuator arm 41, whenever this arm is actuated by an actuating member 40 on the vertical column 3.
  • This mechanism is merely schematically indicated in Figure 2, but can easily be devised by a person skilled in the art.
  • the vertical column 3 has been rotated in the direction of the arrow ⁇ to a point just prior to the activation of the flow switch.
  • the piston rod 43 is displaced towards the cylinder 34, whereby the chain wheels 31 and 32 are rotated in the opposite direction.
  • the column 3 is rotated once in the direction indicated by the arrow ⁇ , whereafter the direction of rotation is reversed and the column 3 rotates a full 360 degrees in the opposite direction and so on.
  • the pivot arm 23 carrying the nozzle section 8 oscillates in the vertical plane as described in connection with the first embodiment and according to the second embodiment, the ray of washing fluid leaving the nozzle section 8 of the cleaning device thus describes a kind of sinusoidal pattern within a given vertical region surrounding the cleaning device.
