Definitions

  • ABSTRACT A self-propelled air-punching mechanism for making [21] Appl' 102672 holes in soil by its compaction, in which a hollow body is provided with a pointed head section with a striker [52] U.S. Cl ..l75/ l9, 173/137 being located within the body and forming therewith [51] Int. Cl. ..E2lb 11/02 from and rear p s chambers. and the from [58] Field of Search ..173/ 135, 137; 175/19, 92 Chamber munic ing wi h n addition l pa within the pointed head section of the body, thus raising the impact power of the mechanism.
  • the present invention relates to self-propelled per-' cussive mechanisms, and more particularly to selfpropelled air-punching mechanisms used for making holes in soil by its compaction.
  • a self-propelled air-punching mechanism to make holes in soil by its compaction comprising a body pointed on one side thereof, and housing a striker forming a front pressure space located between the body and the outer surface of the striker, with such space at regular intervals communicating with the source of compressed air and the atmosphere, and a rear pressure space located inside the striker in the tail section thereof, and permanently communicating with the compressed air source.
  • the striker imparts impacts to the body while reciprocating under the effect of compressed air delivered to the pressure spaces through an air supply sleeve coacting with the striker, and fixed in the tail section of the body.
  • the object of our invention is to provide a selfpropelled air-punching mechanism which has a higher impact power on the account of an increased volume of the front pressure space, without changing the weight of the mechanism.
  • a self-propelled airpunching mechanism to make holes in soil by its compaction comprising a hollow body having a pointed head section, the body housing a striker defining in the body a front chamber of variable volume, the striker having a tail section in which is provided a rear chamber of variable volume, the striker impacting impacts to the body while being reciprocated therein by compressed air delivered to the chambers through an air supply sleeve located in a rear chamber of the striker, and fixed in the tail section of the body.
  • a space which communicates with the front chamber of variable volume through channels formed in the body.
  • the increase of the front chambers volume in the present mechanism by making the inner space in the pointed head section of the body raises the impact power of the striker without any deterioration of the operational qualities of the mechanism.
  • the self-propelled punching mechanism shown in the drawing comprises a body 1 having a pointed front section, with the body consisting of a tip 2, a fairing 3, an anvil 4 secured to body 1, and a cylinder 5.
  • a striker 6 Located inside the cylinder 5 is a striker 6.
  • the tip 2 of the body 1 is provided with an inner space 2a and disposed between the inner surface of the cylinder 5 and the outer surface of the striker 6 is a front chamber 7 of variable volume, and the chamber 7 through air channels 8 in the anvil 4, communicates with the space 20.
  • the chamber 7 and the space 2a constitute a single pressure chamber.
  • a space 9 of variable volume Inside the tail section of the striker 6 is provided a space 9 of variable volume, and stepped air supply sleeve 10 is inserted into the space 9, with the space 9 defining the rear pressure chamber of the mechanism.
  • the walls of the striker 6 are formed with ports 11 to provide communication between the single front chamber 2a, 7, 8 and the rear pressure chamber 9.
  • the stepped sleeve 10 is attached to the tail of the cylinder 5 by means of a flexible coupling 12 and a nut 13.
  • the coupling 12 has channels 14 to exhaust the return air to the atmosphere.
  • hose 15 Secured to the rear end of the sleeve 10 is a hose 15 within the sleeve 10 is a channel 16 to supply air to the pressure chambers 2a, 7, 8, and 9. i
  • the mechanism operates as follows:
  • the striker 6 After its impact against the anvil 4, the striker 6 under the effect of the rebound and the force produced by air pressure in the single front chamber 2a, '7, 8 starts moving back. In the further movement of the striker 6, the ports 11 are closed by the side surface of the sleeve 10.
