SCRAPING DEVICE WITH LIFTING SIDE SCRAPING DEVICES

The present invention relates, in general, to a scraping device intended to cause scraping of the waste present on the surface of a soil, more particularly with a view to its elimination.

The invention finds particular application in the field of animal husbandry, for the evacuation of manure or slurry in the corridors of exercises. By stable is meant buildings for raising animals such as cattle, sheep, horses or pigs.

There is a known scraping device composed:

- a lifting shovel, which in forward position is in the low position and pushes the waste in front of the scraping device,

- two side flaps, positioned on either side of the shovel, which have the function of automatically adapting the scraping width to the width of the corridor containing the waste, by leaning on the edges of the corridor.

These side flaps have one of their ends in pivot connection with a vertical axis with one end of the main body of the scraping device, and are oriented towards the front. This provision allows:

- in forward, a natural opening of the shutters, which then lean against the edges of the scraper corridor,

- in reverse, a natural orientation of the flaps in a direction parallel to the path, which minimizes the entrainment of waste.

However, the scraping carried out remains perfectible.

The technical problem which the invention aims to solve is therefore to improve scraping of waste by means of a device for scraping soil.

To this end, a first object of the invention is a scraping device intended to drive, by scraping, the waste present on the surface of a soil, the scraping device comprising:

- a main body arranged to move on the ground,

- a front scraping device mounted at the front of the main body,

- side scraping devices mounted on your sides of the main body.

According to the invention, each lateral scraping member is mounted on the main body via a separate intermediate support articulated on the main body around a corresponding axis of rotation, called the proximal axis of rotation, the corresponding lateral scraping member being articulated on this intermediate support around a corresponding axis of rotation, called the distal axis of rotation.

For each intermediate support, in the scraping position of the ground, a first axis among the distal and proximal axes of rotation is substantially vertical and a second axis among these axes of rotation is transverse to a substantially vertical plane. For example, this said second axis can be horizontal.

The scraping device also comprises:

- a mechanism for actuating the lateral scraping members according to a rotational movement around the second axis between the scraping position of the ground and a raised position, and

- means for limiting the lateral scraping members in rotation about the first axis so that in the raised position the lateral scraping members are at a distance from the ground.

Thus in the scraping position, moving forward will cause natural opening of the flaps, by rotation around the first axis, which can then lean against the edges of a scraper lane. By natural opening is meant that this opening will be done without a specific actuation of the opening movement by a motor. Here it is, the advancement of the scraping device which causes the opening of these lateral scraping members, in particular by friction against the ground, until they come into abutment against the walls of the corridor.

However, it is possible to lift the lateral scraping members by rotation around the second axis. In this case, the means for limiting rotation about this axis allow the lateral members to be kept away from the ground.

Thus, it is possible to carry out a reverse gear without any friction, which further minimizes the entrainment of waste, in particular of fibrous material, during a reverse gear. This can in particular make it possible to further improve a scraping by alternating movement or a resumption of scraping over an area.

Furthermore, such a scraping device can also lift the lateral scraping members in forward motion. This allows you to change direction in forward with minimal material training. Such a scraping device is thus particularly suitable for use without guide means, such as a groove or a rail cooperating with guide members of the scraping device, to ensure that the latter moves in a rectilinear manner up to to a waste collection area. In particular, the scraping device can be self-propelled and self-directional, without harming the quality of the scraping.

The invention can optionally have one or more of the following characteristics:

the first axis is the distal axis of rotation and the second is the proximal axis of rotation; one can thus place the actuating mechanism, at least in part, in the main body;

the second axis is arranged in a direction from front to back; this allows a simple approximation of the lateral scraping members towards the longitudinal axis of the scraping device, and therefore a separation of the walls of the corridor;

said limiting means comprise stops arranged so as to oppose a rotation of the lateral scraping members downwards when these lateral scraping members are in the raised position; so it is by simply pressing the stop that rotation around the first axis can be blocked; in particular, for each intermediate support, at least one stop is arranged on the intermediate support or on that of the main body or of the lateral scraping member with which this intermediate support is articulated;

a first intermediate support is mounted on the left side of the doctor device and a second intermediate support is mounted on the right side of the doctor device;

each intermediate support is a plate; it’s a simple way to do it;

the articulation (s) around the proximal axis of rotation and / or the articulation around the distal axis of rotation are hinges; it’s a simple form of articulation;

according to the two preceding paragraphs taken in combination, the hinges are mounted on two adjacent sides of the plate, in particular two sides extending in transverse directions, in particular perpendicular, between them; this allows the intermediate supports to be produced in a simple manner with the two axes of rotation transverse to one another, or even perpendicular;

rotation about the first axis is free; there is therefore no mechanism specifically associated with this rotation, which is therefore a natural rotation;

the scraping device comprises a mechanism for lifting the front scraping member and a means for coupling the lifting mechanism for the front scraping member with the actuation mechanism or mechanisms for the lateral scraping members, the coupling means , the lifting mechanism and the actuation mechanism being arranged so that the lateral scraping members are in the raised position when the front scraping member is raised; this simplifies the lifting of the scraping members;

the coupling means is a coupling mechanism driven by an actuator and mechanically connected to the intermediate pieces and to the front scraping member so that the actuation of the coupling mechanism causes the lifting or lowering of the scraping members ; there is thus a reliable means of coupling;

the coupling mechanism comprises cams and a means for driving these cams, said cams being on the one hand arranged to cooperate in displacement with cam tracks integral with the front scraper member and on the other hand mechanically connected to the lateral assemblies formed by each intermediate support and the lateral scraping member that it supports, so that the displacement of the cam in one direction or the other on the one hand respectively causes the raising or lowering of the 'frontal scraping member by displacement of the cam against the cam tracks, and on the other hand respectively causes the raising or lowering of the lateral scraping members by pulling or pushing on said lateral assemblies.

Unless otherwise indicated, the terms "front", "rear", "lower", "upper", "side", "transverse", "longitudinal", "vertical", "horizontal" refer to the orientation of the device scraping on a horizontal floor and in the direction of scraping thereof.

An example of a scraping device 1 according to the invention is illustrated in the scraping position in FIGS. 1 to 5.

This scraping device is in particular called scraper 1 and is intended to cause scraping of the waste present on the surface of a floor, such as a corridor in a stable.

This scraper 1 comprises a main body 2 arranged to move on the ground. In this example, the scraper 1 comprises four wheels 8, possibly with two steered wheels.

According to the invention, as in this example, it can be a self-contained scraper 1, the movement of which is driven by a motor driving at least one of the wheels 8. This scraper 1 can be guided by various known means .

In order to scrape the self in front of it, the scraper 1 comprises a front scraper member 3 mounted in front of the main body 2 and allowing it to push the waste in front of it. This front scraping member will be referred to below as an excavator 3.

The scraper 1 also comprises lateral scraping members 4, hereinafter called lateral flaps 4. The latter can, as here, be mounted on the sides of the main body 2, at the front thereof, on both sides other of the shovel 3. So they point forward.

As can be seen in these figures, the side flaps are indirectly mounted in an articulated manner on arms 21 of the main body 2, extending laterally with respect to the rest of the main body 2. More particularly, the side flaps are each mounted on these arms 21 via a corresponding intermediate support 5.

Like the intermediate supports 5, the arms 21 and the side flaps 4 are symmetrical in these drawings, the same references are used.

The intermediate supports 5 left and right are articulated respectively on the right arm 21 and on the left arm 21 via proximal hinges 52, which are horizontal in the scraping position. Thus, these intermediate supports 5 are articulated on the main body 2 around a proximal axis of rotation P, here horizontal in the scraping position.

In general, the proximal axis of rotation P can be transverse to a vertical plane. In such a case, this axis is therefore oblique. The side flaps 4 and the intermediate support 5 being arranged to scrape the ground in the scraping position, this oblique axis allows the lifting of the side flaps around this axis of proximal rotation P, More particularly, the axis of proximal rotation P can be included in a plane parallel to the longitudinal direction X of the scraper 1, or scraping direction X. In the example illustrated, the proximal axis of rotation P being horizontal, it is therefore perpendicular to a vertical plane extending transversely and is so parallel to the scraping direction X,

Furthermore, the side flaps 4 right and left are mounted articulated on the intermediate supports 5 right and left, via distal hinges 51, which are vertical in the scraping position. Thus, these side flaps 4 are articulated on the intermediate supports 5 corresponding around a distal axis of rotation D, vertical in the scraping position.

Each intermediate support 5 is here formed by a plate 50, the hinges 51, 52 are here mounted on two adjacent sides extending in directions perpendicular to each other.

In addition, the scraper 1 comprises an actuating mechanism 6 of the intermediate support 5, and therefore here side flaps 4, according to a vertical rotation movement around the proximal axis of rotation P between the scraping position of the ground and a raised position, illustrated in FIGS. 6 to 9, This actuation mechanism 6, of which an intermediate link 55 can be seen in FIGS. 5 and 6, will be described later.

In this example, the rotation around the distal axis of rotation D is free. Thus, when the side flaps 4 are in the scraping position and the scraper 1 advances, the side flaps 4 rub against the ground. As a result, the free ends 41 of these side flaps 4 naturally move away from one another in a horizontal rotational movement around the distal axis D, until they come to bear on the edges of the corridor to clean. Thus, the side flaps 4 form an opening angle on either side of the shovel 3, allowing the waste to be brought down towards the center.

According to the invention, as can be seen in FIG. 5, in the scraping position, each intermediate support 5 can be in the folded position against the corresponding arm 21, the plate 50 being pressed against this arm. This makes it possible to strengthen the holding of the side flaps 4 when the waste is pushed by the scraper 1,

The actuation mechanism 6 is capable of being activated so as to lift each intermediate support 5, here by the thrust of an intermediate link 55 linked to plate 50 below the proximal hinge 52. The bottom of the plate 50 s' then moves away from the arm 21 and rises, thereby raising the distal hinge 51 and therefore the corresponding side flap 4. FIG. 6 shows the positioning of the left side flap 4 and the left intermediate support 5 in the raised position.

Due to this raising, the distal hinge 51, here carried by a vertical side of the plate 50, as well as the distal axis D pass in an oblique position. Therefore, gravity drives the free end 41 of each side flap 4 downward, therefore in a rotational movement which would correspond in the scraping position to a movement of reduction of the opening angle of the side flaps 4 between them, but which due to the orientation of the distal axis of rotation D in the raised position, corresponds to a folding of the side flaps 4 downwards.

In order to limit this downward folding movement, each lateral flap 4 here comprises a stop 53 coming to block this rotational movement, so that in the raised position the lateral flaps 4 are at a distance from the ground.

As here, this stop 53 can be formed in the extension of the corresponding side flap 4, the side flap 4 extending between its free end 41 and this stop 53, The stop 53 is here behind the distal hinge 51 and below that - in the raised position. It is therefore also below the plate 50. Therefore, in the raised position, the stop 53 comes to bear against the underside of the plate 50, here blocking the side flap 4 in the extension of the plate 50. There is thus a firm locking of the downward movement according to a rotation around the distal axis D, The side flaps 4 are thus kept at a distance from the ground.

The production of such a stop 53 also makes it possible to give the side flaps 4 a determined position.

Once the shovel 3 and these side flaps 4 are raised, it is then possible to move forward, but above all to back off or turn, without causing fibrous material. The scraper 1 can therefore scrape more effectively in reciprocating motion.

In a stable, the corridor can lead into a pit or a conveyor belt for transporting waste to a pit. The scraper 1 can push the waste towards this pit or this conveyor belt, and once arrived at the end of the corridor, it can turn around or change direction by entraining a minimum of fibrous material.

This scraper 1 can also circulate from one corridor to another having a width and an opening angle of the side flaps 4 less than the width of the corridor, without the need for borders. The raised side flaps 4 then prevent him from stumbling into the lateral obstacles that he might encounter.

The lifting of the shovel 3 can be coupled with that of the side flaps 4.

For example, according to an embodiment not shown, the scraper may include specific motors for each lift, the activation of these motors being coupled by electronic equipment together forming a means of coupling a mechanism for lifting the shovel with the or the actuation mechanisms of the side flaps.

According to another embodiment, such as that illustrated, this coupling means is formed by a coupling mechanism.

The lifting, actuation and coupling mechanisms will now be described with reference to FIGS. 10 to 13,

The scraper 1 comprises a lifting actuator, not shown, since it is situated behind the cutting plane in FIG. 10. This actuator rotates a pinion 10 visible in FIG. 10, the axis of rotation of which is longitudinal. The pinion 10 meshes with a first toothed wheel 11 of larger diameter, so as to form therewith a speed reducer, thus making it possible to increase the torque exerted by the motor. Here, the first gear 11 rotates around a longitudinal axis.

As can be seen in FIG. 11, a second toothed wheel 12 is fixed to the front face of the first toothed wheel. The axis of rotation of the second gear 12 is coaxial with that of the first gear 11. This second gear 12 meshes up and down with respectively an upper rack 14a and a lower rack 14b located in front of the first toothed wheel 11. These racks 14a, 14b are arranged horizontally and transversely. They are guided in horizontal and transverse translation by grooves 13a and 13b, here arranged in the plane of the first toothed wheel 11 and visible in FIG. 10, for example, studs, not visible in these figures, can be arranged on the faces rear of the racks 14a, 14b so that these studs slide in the grooves 13a, 13b. Thus the actuator drives the racks 14a and 14b in a horizontal and transverse translational movement in one direction or the other.

Each rack 14a, 14b comprises at its end situated on the side of the scraper 1 a cam 15a, 15b, formed here by a tenon. The upper rack 14a thus carries a cam 15a located on the left (ie on the right in FIG. 11) and the lower rack 14b thus carries a cam 15b located on the right. The actuator can therefore drive these cams 15a, 15b by moving them apart or by bringing them closer to one another according to the direction of rotation that it gives to the pinion 10,

FIG. 12 being a half-section, it represents on the left the actuation mechanism 6 of the right intermediate support 5. The right side flap 4 is not shown for the sake of clarity of the drawings, On the right of FIG. 12, the left side flap 4 is shown.

This actuation mechanism 6 comprises for each side flap 4: a connecting rod 56, an intermediate link 55 and a distal link 54,

The rod 56 extends generally transversely and comprises at a first end a light 57, inside which the corresponding cam 15a can slide, the second end of the rod 56 is connected to a first end of the intermediate rod 55, which extends transversely and the second end of which is connected to the first end of a distal link 54, the latter is here fixed by its second end perpendicular to the plate 50 of the corresponding intermediate support 5 and forms an angle with the intermediate link 55 in the raised position.

The lifting mechanism comprises a vertical plate 30 which carries the shovel 3, Each tenon forming the cam 15a, 15b projects forward of the light 57, The plate 30 carries a cam path 31/32, The latter is formed by a horizontal portion 32 on the side of the scraper 1 and an oblique portion rising from the horizontal portion 32 and away from it.

As can be seen in Figures 12 and 13, the right cam 15b cooperates with the visible cam track 31/32. Due to the half-cut, this is not visible, but a symmetrical cam path is arranged on the other side of the scraper, in the portion not cut in these figures, so as to cooperate in the same way with the left cam 15a,

To lower the right side flap, the actuator brings the cams 15a, 15b towards each other. Each cam 15a, 15b moves further inward and passes from an external end of the light 57 to an internal end 57 'of this light 57, In doing so, each cam 15a, 15b slides against the horizontal portion 32 of the path corresponding cam.

When each cam 15a, 15b reaches the oblique portion 31 of the corresponding cam path, the plate 30 descends under the effect of gravity with the oblique portion 31 bearing on this cam 15a, 15b, This descent will continue as and as the cam 15a, 15b changes along the oblique portion 31, that is to say for the right cam 15b of its movement towards the left of the scraper 1. The plate 30 being integral with the shovel 3, there is thus a lifting mechanism, causing the shovel 3 to descend by bringing the cams 15a, 15b together.

When the cam 15a, 15b reaches the internal end 57 ′ of the light 57, it pulls the connecting rod 56 and therefore the bottom of the intermediate support 5 via the transmission chain formed by the connecting rods 55, 54. Thus, the bringing together of the cams from one another causes the intermediate supports 5 to be folded back in rotation about the proximal axis P and against the arms 21. Thus, the side flaps 4 pass into the scraping position of the ground.

In this example, the length of the horizontal portion 32 of the cam track is shorter than the length of the light 57. Therefore, each cam 15a, 15b approaches the oblique portion 31 of the cam track before touching the end internal 57 ′ of the light 57. In this example, the shovel 3 therefore here begins to rise before the side flaps 4.

At the end of the traction movement on the intermediate supports 5, the shovel 3 and the side flaps 4 are raised.

Conversely, to raise the side flaps 4 again, the actuator drives the pinion 4 in the other direction, so as to separate the cams 15a, 15b from one another. Each cam 15a, 15b evolves along the oblique portion 31 of the cam path, causing the mounting of the plate 30 and therefore of the shovel 3. The cam 15a, 15b also evolves along the lumen 57 and, when abuts with the outer end thereof, it drives the connecting rod 56 outwards, which via the transmission chain 55, 54, transmits a thrust from the bottom of the intermediate support 5 and therefore the lifting of the side flap 4 corresponding. Here too, there is an offset, the shovel 3 starting to descend before the side flaps 4.

Thus the lifting of the shovel 3 and that of the side flaps 4 are coupled.

In this example, the actuation mechanism, the lifting mechanism and the synchronization mechanism therefore share common elements, in particular the actuator and the gears. The coupling mechanism includes the racks with the cams 15a, 15b and the cam tracks 31/32. The actuating mechanism also comprises the movement transmission chain from the second toothed wheel 12 to the intermediate supports 5. The lifting mechanism also comprises the movement transmission chain from the second toothed wheel 12 to the plate 30.
