  • the device of the invention comprises a base 1 on which a container 2 is mounted.
  • the base is equipped with two rear wheels 11, spaced according to the width of the base 1 and two directional wheels 12 which are arranged side by side on the front edge of the base 1, on either side of the longitudinal axis of the base.
  • the device can move back and forth according to the longitudinal dimension of the base 1.
  • the front wheels 12 make it possible to steer and in particular rotate the device.
  • the device comprises a motor (not referenced), a suction system which comprises a suction pipe 31 and a suction block 32 which forms the cover of the container 2.
  • the free end of the suction pipe 31 is connected to a suction nozzle 33.
  • Pipe 3 is flexible while nozzle 33 is rigid.
  • the nozzle 33 is removable from the pipe 31.
  • the nozzle 33 comprises gripping means 331 which are able to cooperate with the operator's forearm and with the latter's hand, like a crutch.
  • the free end of the nozzle 33 is equipped with a support wheel 332 which allows it to be held on the ground and made to roll in order to facilitate the use of the device of the invention.
  • the base 1 includes a platform 13 on which an operator can stand. At the front of the platform 13 is a vertical protective portion 15, perpendicular to the base 1.
  • the two directional wheels 12 are coupled to the drawbar 7 which makes it possible to control their rotation around a vertical axis by relative to the base 1.
  • the drawbar 7 is also articulated in rotation around a horizontal axis parallel to the width of the device.
  • the drawbar 7 can be brought into a vertical position as shown on the Fig. 1 or in a substantially horizontal position which allows the base 1 to be towed. In its vertical position, the drawbar 7 is clipped onto the protective portion 15 at the level of blocking means 152.
  • Return means 153 here formed by a jack, make it possible to return the drawbar 7 to its vertical position and to block it in the blocking means 152.
  • the free end 71 of the drawbar 7 comprises the control means 73 of the motor of the base 1.
  • the weeding arm 9 is mounted so removable next to the front directional wheels 12.
  • the weeding arm 9 will be described in more detail with reference to Fig. 1 and 2 .
  • the weeding arm 9 includes a rotating brush 91, which includes a tuft of filaments 912.
  • the filaments are in this case steel cables capable of weeding/tearing/uprooting low plants, such as new shoots or moss. .
  • the weeding arm 9 extends beyond the base 1 according to the direction of movement of the device.
  • One end of the weeding arm 9 is slidably mounted on a tube (not referenced) acting as a rail and secured to the base 1.
  • a fixing wheel (not shown) allows the weeding arm to be fixed on this tube by friction of the end of the threaded rod of the wheel on the tube forming the rail.
  • the weeding arm 9 comprises a rectilinear portion 92 which is extended by a fixing tube 921, which protrudes in the direction opposite to the brush 91.
  • This tube 921 fits into the tube forming a rail which equips the base 1.
  • the weeding arm 9 also comprises a substantially vertical connection sleeve 93, arranged near the tuft of filaments 912. This connection sleeve 93 is capable of being connected with the free end of the pipe 31, once the latter is removed from the nozzle 33.
  • a rotary electric motor 95 is placed on the arm 9 and coupled to the brush 91. It has its own control means and makes it possible to drive the brush 91 in rotation. It also includes a speed variator which makes it possible to choose the rotation speed of the brush 91.
  • the suction sleeve 93 and the brush 91 form an integral assembly which is mounted to rotate on the rectilinear portion 92 at the level of an axis of rotation (not referenced) horizontal and parallel to the width of the base 1.
  • a jack 96 connects the block formed by the brush 91, its motor 95 and the connection sleeve 93 and allows the articulation of the latter around the axis aforementioned between a position of use in which the end of filaments of the tuft 912 are close or even in contact with the ground (the weeding arm is then straight) and a rest position in which the brush 91 is pivoted and the hairs are away from the ground, thus not disturbing the progression of the device of the invention.
  • the cylinder 96 is an electric cylinder; it is connected to the power supply of the brush motor 95. It includes a switch which allows it to be activated so as to raise the brush.
  • the weeding arm 9 comprises means for guiding the debris which also act as means of protection/isolation of the brush 91.
  • These guiding means comprise an elastically deformable skirt 97 which partially surrounds the brush 91.
  • This skirt 97 forms a arc of a circle and extends over at least one diameter of the brush 91.
  • the lower end of the connection sleeve 93 comprises a suction head 98 also made of deformable material.
  • the suction head 98 forms a tube which extends the connection sleeve 93 advantageously to the ground (advantageously to the level of the free end of the filaments of the brush 91).
  • the suction head 98 is therefore located near the tuft of filaments 912. It has in its lower part facing the filaments of the brush 91, a suction notch through which plant or other debris is sucked up.
  • the suction head does not touch the ground; this is a variation.
  • the weeding arm 9 When the operator cleans an area by suction, the weeding arm 9 may or may not be removed from the base 1. If it is mounted on the device, it is placed in the rest position. The pipe 31 is connected to the nozzle 33 and the operator can thus vacuum up waste or others located in the area to be cleaned. If it turns out that the area also needs to be weeded, the operator mounts the weeding arm 9, if the latter is not already mounted on the base 1. He disconnects the nozzle 32 and connects the end of the pipe 31 to the sleeve 33, more precisely at the upper end of the latter. It then activates the cylinder 96 in order to pivot the sleeve 93 and the brush 91 into the position of use shown on the Fig. 1 and 2 .
  • Drawbar 7 is in its vertical position.
  • Brush 91 pulls up plants and removes dirt or any other substrate.
  • the debris thus formed is sucked up by the suction head 98, at the level of its notch.
  • the skirt 97 guides the debris towards the suction head 98. The latter, by scraping the ground, stops the debris and facilitates their suction by placing them just under the sleeve 93.
