Definitions

  • the present invention relates to planting equipment of posts, intended to be installed on a transport vehicle such than a tractor.
  • the invention further relates to poles usable with such equipment as well as fences or feasible installations with such equipment and poles.
  • the present invention aims to achieve equipment planting of poles of simple and effective design.
  • the invention particular aim of developing a feasible fence system with this equipment.
  • This equipment makes it possible to plant oriented poles of accurately regardless of the inclination of the ground. This orientation can be vertical as is often the case. But it is also possible to carry out work along a different axis. This line of work can be set automatically or by the operator.
  • This equipment offers a great flexibility of use because of the simplicity and robustness of its structure.
  • This structure simple allows the equipment to be used in difficult conditions, example in areas of difficult access. Because of this simplicity, the equipment is very easily controllable and the driver of the equipment can work precisely so as to position the location of the work, ie the tool at the precise location that to control the evolution of work. The positioning of the tool is done precise way even in irregular terrain since the driver can not only to orient the mast but also once the vehicle stopped near the work site, move the tool holder by the moving frame transversely.
  • the equipment may be mounted on a vehicle such as a tractor, in particular an agricultural tractor, on its coupling in three points, either at the front or at the back. It is however preferable for make the work easier that the tool is perfectly visible from driving position and that the vehicle equipped with the equipment is a vehicle particular, either wheeled or chain.
  • This equipment can also be installed on a platform rotation carried by the vehicle and in this case the flexibility of use is even greater because the driver will not only have the translation of the mobile frame relative to the mast to position the tool but it can also combine this possibility with a pivoting.
  • the mast may consist of a single piece telescopic for some applications, it is interesting to have a greater working height than that offered by a single mast whose height is necessarily reduced to comply with the regulations or to facilitate the movement of the vehicle on not necessarily cleared at the top, so it is interesting that the mast is a telescopic mast.
  • This realization of the frame is particularly simple and robust since it is limited to the functional elements. This robustness also makes it possible to effectively absorb the forces transmitted by the tool to the tool holder.
  • the toolholder comprises an engine hydraulic axis rotation parallel to the axis of movement of the sled along the mast.
  • This hydraulic motor is powered by the hydraulic system of the vehicle.
  • This chuck can receive various accessories to make such as a drill bit for drilling rock or concrete but especially a pole.
  • the chuck is advantageously equipped hydraulic cylinder integrated in the clamping cone and chuck body to tighten the chuck, its opening being provided by springs of recall.
  • the interchangeability of the jaws is very simple since the jaws are controlled by translation of the clamping cone working by ramp effect cooperating with the back of the jaws.
  • This back, frustoconical shape is adapted to the shape of the clamping cone.
  • the restraint between the cone clamping and jaws is ensured easily by magnetic attraction. This magnetic attraction exercising mainly in the direction perpendicular to the contact surface between the clamping cone and the body chuck but not in a perpendicular direction, does not interfere with translation movement or sliding of the cone on the back jaws.
  • the invention also relates to a fence post or signage that can be planted using equipment according to the invention.
  • This post is characterized in that it comprises a tip formed of a cone with a screw thread to be screwed into the ground. It is particularly advantageous to terminate the cone with a perforation tip to increase its resistance when screwed into the ground.
  • the pole according to the invention has the advantage, on the one hand, of planting easily in the soil, especially with equipment equipped with a mandrel like the one mentioned above. This implementation is done precisely. As the post is screwed, its sinking into the soil does not alter the surrounding soil structure as is the case for a beaten post, the soil being simply compacted by the repression the volume of land occupied by the tip of the pole. The post is also independent of the quality of the tip as is the case of wooden poles whose tip is cut.
  • the rotational movement also has the advantage of spreading obstacles and not to blunt or warp the tip like this is the case of a wooden pole which, encountering a particular obstacle hard, sees its point crushed, broken or deviated, which complicates its precise sink.
  • the cone is a metal piece provided with a screw thread made of sheet metal.
  • This cone is reported at the end of a post, including a wooden post.
  • the post may be slightly cut at its end to fit in the cone in which it is held by screws or other fastening means.
  • the interior of the cone may also have claws to improve the snap between the cone and the post and transmit effectively the screwing forces exerted by the mandrel on the pole towards the cone.
  • This post can also be disassembled, that is to say from the ground or from the ground using equipment equipped with a mandrel.
  • the mandrel can turn the post in the direction unscrewing both to take it off the ground and to unscrew it. Then, the post may be torn off by the lift of the carriage or by unscrewing.
  • the limited stroke of the chuck jaws is advantageously adapted to the diameter of the pole in a diameter range.
  • the invention also relates to a feasible fence system with poles, crossbars and struts.
  • This system includes assembly parts. Following a advantageous characteristic, preformed assembly parts composed each of at least two branches having at least partially the section of the fence elements to be assembled (post, crossbeam, strut) to receive an element in each branch.
  • the posts thus positioned in a precise way will constitute the fence, which will no longer require adaptation of the sleepers since the interval between the poles will be precise.
  • the assembly poles and crossbeams or struts will be easy and fast to realize thanks to these parts of assembly.
  • the assembly part is composed of of a tubular element whose section substantially corresponds to that of post to receive this post, and at least one perpendicular side branch to the tubular element, this branch being in the form of a half-cylinder circular section substantially corresponding to the section of the crosses.
  • the section of the lateral branch extends tangentially beyond the section in a semicircle to form a drop of water.
  • the element tubular carries at least one inclined lateral endpiece with a covering open section, to receive a leg of strength.
  • branches are equipped holes for screwing or nailing fence elements.
  • the invention relates to a device tillage for excavation or planting work.
  • This equipment is intended to be installed on a transport vehicle for example on the three-point hitch of a tractor or preferably on a vehicle designed for this purpose so that the driver can see the equipment for the execution of the works.
  • This equipment is equipped with a tool holder for a tool drilling such as a drill or auger to make holes in the soil and extract the load.
  • a tool drilling such as a drill or auger
