Abstract: A cleaning device for cleaning artificial floor coverings provided with floor covering particles, such as artificial turf, comprising a sweeping device for gathering dirt particles from the floor covering, a separation device for separating the dirt particles from floor covering particles, a floor covering particle feedback device for gathering the floor covering particles separated from the dirt particles and feeding back the floor covering particles to the floor, a filter device for filtering dust particles, and a suction device which draws air from the area of the separation device through the filter device. First and second negative-pressure chambers in which negative pressure can be formed by the suction device suction are formed above and below the separation device, respectively, in fluid communication through the separation device. The first negative-pressure chamber is in fluid communication with the suction device only via the second negative-pressure chamber.

Abstract: A soil cultivation device, which is movable relative to the soil in a direction of movement, for the deep loosening of soils, comprises perforating tools guided on supporting arms that move up and down, and a damping device having an elastomeric body, for damping a returning movement of the perforating tools pivoting relative to the supporting arm during withdrawal from the soil. For smoother and faster operation, a first side of the elastomeric body is firmly connected to a retaining member, resting flat on a retaining surface of the retaining member, and a second side of the elastomeric body opposite the first side is firmly connected to an input member in a firmly attached manner, resting flat on a retaining surface of the input member, and the body of elastomeric material is elastically biased by a separate biasing device acting against the body.

Abstract: A soil cultivation device drivable in a displacement direction relative to the soil and designed to break up sub-soil. The device has a chassis or frame, a row of support arms and a drive unit, respective cutting tool pivot units pivotally hinged on the support arms to pivot relative to the arms about a second pivoting axis, permitting a cutting tool fixed on the cutting tool pivot units to pierce the soil and the cutting tool pivot units to be pivoted in relation to the support arms. In addition, the device has at least one gear mechanism, which transmits the relative displacement of the cutting tool pivot unit and the support arm, which at least occurs when the cutting tool has pierced the soil and the soil cultivation device is traveling onwards in the displacement direction, to at least one unit not displaced up and down with the support arm.

Abstract: A soil plug processing mechanism for processing soil plugs which occur during ground maintenance. The soil plug processing mechanism having a separating device for picking up and processing the soil plugs by separating the soil plug material into fine particles and coarse particles. The separating device has at least one rotatable rotary sieve which has a rotatably driveable sieve drum with an outside surface which is configured at least partially as a sieve area.

Abstract: A soil treatment apparatus has a plurality of tool units that have at least one bracket, at least one plunger tool and at least one stop for the plunger tool. The bracket with an end section on a chassis is driven up and down to pivot about a first pivoting axis. The plunger tool device is linked at another end section of the bracket to pivot about a second pivoting axis. The stop is formed such that plunging is carried out at a predefined plunging angle. To enable faster operating speeds, the first pivoting axis is provided behind the second pivoting axis as seen in a driving direction, and the plunger tool device is linked such that whenever the bracket is pivoted about the first pivoting axis it is subjected to a centrifugal force in a direction toward a position limited by the stop.

Abstract: The invention relates to a soil-working implement (1, 2) for subsoiling (22), having a series of carrying arms (25), of which each is mounted by way of a first region, in particular a first end region, on an implement frame (20) or an implement chassis such that it can be pivoted up and down about a first pivot axis (26), having a crankshaft (34) with at least one crankshaft journal (38), having in each case at least one cutting tool articulation device (30) for articulating a cutting tool (32) on a second region, in particular a second end region, of each carrying arm (25), and having at least one crank connecting device (29) per carrying arm (25), this device connecting the cutting tool articulation device (30) to the at least one crankshaft journal (38) of the crankshaft (34) for the purpose of driving the up and down movement guided by the carrying arm (25).

Abstract: The invention relates to soil cultivating device (1) which can be driven or connected to a vehicle. Said soil cultivating device comprises tools (3) which are guided in the direction of the soil that is to be cultivated and a rotatably driven crankshaft (7) actuating said tools (3). In order to facilitate production and maintenance while ensuring a faster working speed and improving handleability and possibly also reducing the requirements to be met by the traction vehicle or supporting vehicle, the crankshaft (7) is driven from at least one lateral end area of the extension thereof, which is located perpendicular to the direction of motion.

Abstract: A movable implement for loosening soil below ground, in which a row of blades with blade holders are located perpendicular to a direction of motion of the implement. A supporting arm has one end articulated to each blade, and a frame is articulated to another end of the supporting arm. The supporting arm is engaged by a connecting rod of a crank device, which operates in a vertical plane parallel to the direction of motion. The supporting arm mounts a blade adjustment lever with two arms. The adjustment lever pivots coaxially with an articulating shaft. A stop is mounted on a downward-extending arm of the blade-adjustment lever, and points below the articulating shaft. A lever-adjusting device has a variable angle to the supporting arm for varying the angle of the blade to the ground. A spring forces a blade holder against the stop. The blades are forced away from the stop during movement of the implement.

Abstract: The invention relates to a mowing machine with at least one blade (4) rotating about a spindle (3), preferably with two mowing cutters (6) arranged symmetrically to the spindle, and preferably with several and especially three blades (4) rotating about parallel spindles (3), which is/are arranged in a mower housing (1) with the cuttings ejected towards the rear (regarded from the direction of mowing). In order to provide a mulch from the cuttings with such a mower, it is proposed that the blade(s) (4) be contained in the ejection direction by a wall system (8, 9).

Abstract: The invention concerns a device (1), which is self-powered or can be connected-up to a vehicle, for loosening the sub-soil, the device having an array of piercing tools (13) mounted substantially perpendicular to the direction of travel of the device. Before driving into the soil, the tools are oriented by means of a jointed-rod parallelogram, independently of the penetration depth selected (the penetration depth is adjustable). The position of the link rod (21) running approximately parallel to the chassis-mounted linkage between the two chassis-mounted bearings (7,8) can be altered by pivoting the piercing tool (13) or its mounting (14), against the bias of a spring (22), in a direction away from a stop (23) while the tool is executing the loosening movement in the soil.
