Definitions

  • the invention relates to a device for the pneumatic or gaseous catapulting of loose objects, in particular articles fastened to a cable, in particular a linen bag, and a method for this and a production method of the aforementioned device.
  • a line throwing device for rope climbing equipment in tall trees.
  • a projectile is thrown by a pressure of air through a throwing pipe in the air.
  • the tree care and the tree seed harvest as well as the cone picking are advantageous.
  • a throwing body At the end of a throwing line a throwing body is attached and thrown over a selected branch fork in the height of the tree. Due to the weight of the throwing body, the throwing line is pulled over the branch.
  • the projectile seals the pipe in the throwing pipe with a rubber plate and a seal, so that underneath a pressure chamber with compressed air can be achieved.
  • a mechanical lock is released.
  • a throwing machine which includes a two-meter-long fiberglass poles and a rubber for catapulting.
  • the presented throwing device could also be suitable for fishing on angling.
  • the object is to provide a device and a method of production and method for catapulting, which allow a simple and rapid production of the device and realize a precise method for catapulting loose objects.
  • the apparatus for pneumatically or gaseously catapulting loose objects is formed with an acceleration tube, a pressure chamber, a first actuatable expansion valve and a second loading valve, wherein the acceleration tube is formed at one end of a fluid line from the expansion valve as an extension and on the opposite end of the fluid line as Extension the pressure chamber is formed.
  • the charging valve is formed in direct fluid communication with the pressure chamber and the catapultable object is loosely inserted into the acceleration tube in the run in front of the expansion valve and / or laid.
  • Such a construction of a device is very simple.
  • the catapultable object can be designed as desired.
  • a seal to the acceleration tube is not required.
  • a seal to the accelerator tube would also be a hindrance, as this would cause a friction that counteracts the acceleration force.
  • Such a device comprises few components and is very effective, whereby articles can easily be catapulted between 10 to 300 m at a corresponding pressure. Further advantages of this pneumatic projectile throwing device are that a minimal effort is achieved with a higher aiming accuracy, thus the implementation with the object of the throwing is considerably faster. Furthermore, the device is extremely robust and has a very low wear and an increased life.
  • the invention is manual pumping power, which is spent, for example, by manual muscle power to introduce pneumatic energy into a pressure chamber and controlled trigger this with a manual or electrically controllable lever.

  • the advantage is that finished valves are known and available in standard sizes. The operation is easily varied with a hand lever.
  • the hand lever has several advantages. One advantage is that the force for catapulting is controllable with the hand lever. If the ball valve ball valve opens quickly, the pneumatic pressure force expands very quickly and the loose object is accelerated very far with a high force. On the other hand, if the ball valve ball valve is opened slowly or only with a smaller gap, only a small acceleration force is generated.
  • the ball valve ball valve is electrically controlled by means of an electric drive. Thus, the opening operation of the expansion valve is still precisely reproducible.
  • the acceleration tube and the pressure chamber are substantially identical tubes.
