  • the legs 303, 304 have a gap 305 between them in which the lip 20 is received in a tongue-in-groove fashion to mount the lip shroud 30 to the lip 20.
  • the lip shroud 30 has opposite sides 306.
  • the sockets 302 are defined in each of the sides 306.
  • a socket passage 308 leads from the gap 305 to the socket 302.
  • the socket passage 308 is open to the socket 302 via a passage opening 310 between each socket 302 and socket passage 308.

  • the nose 401 has a spigot which is shaped to be received in a socket of the tooth 420.
  • the jaw 403 comprises an upper leg 405 and a lower leg 406 which are adapted to receive part of the lip 20 between them.
  • the adaptor 400 is mounted to the lip 20 and fixed to the lip 20 by welding the upper leg 405 and the lower leg 406 to the lip 20.
  • the head 521 of the key 520 and the upper end 512 of the body member 510 have alignment markings 570.
  • the alignment markings 570 reveal the rotational orientation of the key 520 relative to the body member 510.

  • the bush 525 seats against the shoulder 516 in the bore 515.
  • the bush 525 is resiliently compressed by applying a downward force to the head 521 of the key 520. Compressing the bush 525 moves the shank 523 downwardly relative to the body member 510 so that the dowel pin 528 is spaced from the lower end 514 of the body member 510.

Abstract

L'invention porte sur un ensemble élément d'usure pour un couvercle de dispositif d'excavation du sol, lequel ensemble comprend un premier élément d'usure, un second élément d'usure et une goupille de retenue. Le premier élément d'usure est monté sur le couvercle. Le premier élément d'usure comprend une protubérance s'étendant vers l'extérieur à partir d'un de ses cotés opposés. Le second élément d'usure est monté à coté du premier élément d'usure. Le second élément d'usure comprend un emboîtement dans l'un de ses cotés. L'emboîtement est conçu pour recevoir la protubérance du premier élément d'usure. Le second élément d'usure comprend un passage de goupille de retenue en communication avec l'emboîtement. La goupille de retenue est localisée de manière amovible dans le passage de goupille de retenue. La goupille de retenue a une première face portante conçue pour être opposée avec une face de la protubérance reçue dans l'emboîtement et venir en prise avec celle-ci et une seconde face portante appuyée contre une face portante du passage de goupille de retenue.
