- the arcuate plate is mounted to pivot freely relative to the frame about the longitudinal axis of the cylindrical brush so as to rest permanently by gravity on the ground.
- the arcuate plate is in the form of cylindrical cap concentric with the cylindrical brush.
- the lower portion of the arcuate plate is bent substantially elongate V whose lower free leg extending rearward of the arcuate plate has an end portion bent upwardly so that the arcuate plate rests on the ground by the rounded connecting edge between the lower leg and the upward curved end portion of the arcuate plate.
- the arcuate plate extends over a height from the ground such that its upper edge is located approximately below the lower edge of the opening of the recovery tank through which the waste is ejected.
- the arcuate plate has two end side walls pivotally mounted to the frame about the longitudinal axis of the cylindrical brush.
- the cylindrical brush can be adjusted to a working height relative to the frame in an arcuate path whose center is located on the longitudinal axis of the front roller.
- the front roller and the rear cylindrical brush extend transversely to the direction of movement of the apparatus.

This brush makes it possible to pick up waste present on the turfed ground for throwing it back by centrifugal force into a collecting or collecting tank. waste 4 secured to the frame behind the cylindrical brush 3.
- the cylindrical brush 3 is in permanent contact with the front roll 2 to constantly clean the periphery of this roll by removing it from the waste deposited on the roll which is projected by the brush 3 into the recovery tank 4.
- the cylindrical brush 3 can to be set at a working height relative to the ground following an arcuate trajectory whose center A is situated on the longitudinal axis of the roller 2 as symbolized by the double arrow F2 in FIG. 3. This working height of the brush 3 depends on the relatively tall on the soil of the turf to be cleaned so that the bristles 3a of the brush 3 can penetrate the turf without touching the ground.
- the cylindrical brush 3 picks up by brushing the waste D present in the grass between the roll 2 and the brush 3 and, at the same time, the brush 2 permanently cleans the front roll 2 to avoid any deposit of waste on the periphery of this roller, thus optimizing the collection of waste because the working height of the brush 3 relative to the ground is kept constant.
- the waste D recovered on the ground and on the roller 2 are projected bristles 3a of the brush 3 upwards and backwards by centrifugal force to be ejected into the recovery tank 4.
- the cleaning apparatus can be coupled to the rear of a machine M intended to defeat the ground itself hitched to the rear of a tractor, not shown, but it is understood that this device can be hitched to the back of any other tillage machine, such as, for example, a soil coring machine, or simply to the rear of a drive tractor by a conventional three-point attachment .

- the front roller 2 is freely mounted to rotate about its longitudinal axis between the two lateral flanges 6. More specifically, each of the ends of the roller 2 is rotatably mounted in at least one bearing of the ball or needle type, not shown, fixed in a bearing support 10 in the form of a substantially diamond-shaped plate secured by fixing screws 11 to the internal face of a support plate 12 of the rear cylindrical brush 3 and which can pivot about the longitudinal axis YY ' of the roll 2 as we will see later.
- the heads 13 of the two fixing screws 11 of the bearing support 10 to the support plate 12 of the cylindrical brush 3 are respectively housed in two arcuate slots 14 formed through each rigid flange 6.
- the two arcuate lights 14 have their center of radius of curvature located on the longitudinal axis YY 1 of the roller 2, which extends perpendicularly to the flanges 6, and are symmetrical to this axis.
- Each bearing support 10 comprises a bush 15 coaxial with the longitudinal axis YY 1 of the roll 2, passing through the support plate 12 of the brush 3 and the corresponding flange 6 so that the assembly constituted by the bearing support 10 and the plate 12 can rotate by a predetermined angular value relative to the flange 6 around the longitudinal axis Y-Y 'during an adjustment of the working height of the cylindrical brush 3.
- Each of the support plates 12 of the cylindrical brush 3 is normally fixed to the corresponding flange 6 by means of two fastening bolts 16 passing through respectively two holes of the plate 12 and two arcuate lights 17 made through the corresponding flange 6 and only one of which is partially visible in FIG. 5.
- the two lights 17 are situated on the same circumference and have their center of radius of curvature located on the axis YY 1 of the roll 2.
- a plate 18 is fixed to the outer face of a portion of each flange 6, not covered by the corresponding wall 7, by the two bolts 16 passing through respectively two holes of the plate 18 which can be locked with the plate 12 to the flange 6 by tightening the nuts 19 of the bolts 16 in a given position of the two arcuate lights 17.
- a means 20 is fixed to each of the plates 18 and allows the adjustment of the working height of the cylindrical brush 3.
- Each adjustment means 20 comprises an internally threaded sleeve 21 fixed, for example by welding, to the outer face of the corresponding plate 18, and a screw 22 passing through the sleeve 21 and whose end opposite its head 23 bears on a stop plate 24 integral with the frame 1 of the cleaning apparatus.
- Each plate 18 comprises a plurality of graduations 25 consisting of small windows that can be brought selectively opposite a fixed reference, not shown, integral with the outer face of the corresponding flange 6 and so as to indicate the working height of the cylindrical brush 3.
- the two plates 12 comprise two parallel arms 12a extending behind the roller 2 towards the recovery tank 4 and between which is mounted to rotate the cylindrical brush 3 which is thus located opposite to a rotor 27 with blades 28 to defeat the ground of the machine M.
- the cylindrical brush 3 is rotated by an electric or hydraulic motor 29 fixed by bolts 29a to the outer face of one of the arms 12a of support of the brush 3 coaxialeraent to the longitudinal axis of the latter so as to drive the brush 3 in the opposite direction of rotation of that of the roller 2 during the movement of the machine M along the direction Fl.
- an operator first loosens the two nuts 19 of the fastening bolts 16 and then with a wrench acts on each screw head 23 22 to drive each screw 22 in one direction or the other to move the bolts 16 in their respective curvilinear lumens 17 in the corresponding direction so as to simultaneously move each plate 18 and each support plate 12 of the cylindrical brush 3 around the longitudinal axis YY 1 of the roll 2.
- the cylindrical brush 3 is moved relative to the flanges 6 and, consequently, the roller 2, along the curved path symbolized by the double arrow F2 in Figure 3 and center on the YY 'of the roll 2.
- the cleaning apparatus further comprises, secured to the frame 1, an arcuate plate 30 concavity facing the cylindrical brush 3 behind the latter and extending substantially over the entire width of the cylindrical brush 3.
- the arcuate plate 30 is in the form of a cylindrical cap concentric with the cylindrical brush 3, that is to say that the radius of curvature of the cylindrical cap is centered on the longitudinal axis X-X 'of the cylindrical brush 3.
- the arcuate plate 30 has its lower portion 31 which is curved substantially in an elongated V or horizontal, one of which 32 of the branch walls is an extension of the arcuate plate 30 and the other lower free branch 33 which extends backwards. of the arcuate plate 30, comprises an upward curved end portion 34 so that an outer rounded edge 35, extending transversely to the direction of travel F 1 of the machine M, is defined between the branch 33 and the curved portion 34. This rounded edge 35 is intended to come into permanent support on the ground during the movement of the machine M as will be seen later.
- the arcuate plate 30 has its upper portion opposite the lower branch 33 extended by a wall 36 curved upwardly rearward of the arcuate plate 30 and the assembly constituted by the arcuate plate 30 and the curved walls 31, 36 extends from the ground of a height such that the free edge of the curved wall 36 is located approximately below and in line with the lower edge 4a delimiting the inlet opening D waste in the recovery tank 4.
- the arcuate plate 30 and its curved walls 31, 36 have two end walls 37 mounted freely pivotable, at their ends opposite to the arcuate plate 30, relative to the frame 1 about the longitudinal axis XX 'of the cylindrical brush 3 so as to rest permanently by gravity on the ground by the rounded edge 35 of connection between curved walls 33, 34.
- each side wall 37 has a bore 37a concentric with a cylindrical sleeve 38 integral with the inner face of the corresponding support plate 12 of the cylindrical brush 3 so that the side wall 37 can pivot freely about the sleeve 38.
- the side plate 37 is held axially on the sleeve 38 by an outer stop ring 39 such as a circlip.
- the arcuate plate 30 is arranged relatively to the cylindrical brush 3 so that the ends of the bristles 3a of the brush 3 sweep in operation successively the arcuate inner face facing the brush of the plate 30.
- the arcuate plate 30 and its curved walls 31, 36 and the side walls 37 may be made of sheet metal.
- the role of the arcuate plate 30, during successive scans by the bristles 3a of the cylindrical brush 3, is to recover waste D not previously ejected by the cylindrical brush 3 in the recovery tank 4 and ensure the transfer of waste D by the bristles 3a of the brush 3 towards the bottom of the arcuate plate 30 so that they can then be taken up by the bristles 3a with other waste present on the ground in order to eject the waste as well as that recovered by the bristles 3 of the brush 3 on the roller 2, in the recovery tank 4.
- the arcuate plate 30 prevents the residual waste D from escaping radially from the row of bristles 3a to prevent them being propelled on the floor behind the brush 3 and this plate retains the residual waste D to its lower edge from which the row of bristles 3a, by the relatively high rotation speed of the brush 3, can retain the residual waste D up to 'to eject them up and back in the recovery tank 4 by the effect of centrifugal force.
- the arched upper wall 36 is located approximately below the lower edge 4a of the waste ejection opening D by the brush 3, it prevents the passage of residual waste not ejected in the tray 4 between the upper edge of the wall 36 and the wall vis-à-vis 4b of the tray 4 comprising the lower edge 4a of the waste inlet opening in the tray 4.
- the arcuate plate 30 thus participates in an efficient and thorough cleaning of the soil by allowing the bristles 3a of the brush 3 to collect all the waste present on the ground just upstream of the lower part of the arcuate plate 30.
- the bristles 3a of the cylindrical brush 3 instead of being arranged in line or in rows as shown in the figures, may consist of several circular parts parallel to each other along the longitudinal axis of the cylinder or be arranged helically. along this cylinder.
- the bristles 3a of the brush 3 may consist of in-line sections of bristles arranged alternately along the brush 3, that is to say angularly staggered in a regular manner on the brush 3. along this one.
- the bristles 3a of the brush 3 may be arranged chevron.
