Adhesively bonded joint in agricultural boom structure

摘要

An adhesively bonded joint in a boom arm of an agricultural sprayer has a tee-shaped brace member with a top flange and a stem extending from the top flange. A brace-receiving portion of the joint has a slot formed therein that receives the stem of the tee-shaped brace member. The sides of the stem and underside of the top flange are adhesively bonded to facing surfaces of the brace-receiving portion. The slot is formed with a v-shape, with the mouth of the slot being wider than the width of the distal end of the slot, to provide some flexibility in the angular positioning of the tee-shaped bracing member. The joint further includes a locking collar around an end of the tee-shaped brace. Opposite sides of the locking collar engage notches on either side of the slot to lock the stem of the tee-shaped brace member in the slot.

主权项

1. An adhesively bonded joint in a boom arm of an agricultural sprayer, the joint comprising:
a tee-shaped brace member having a top flange and a stem extending from the top flange; a brace-receiving portion of a structural member of the boom arm, the brace-receiving portion having a slot receiving the stem of the tee-shaped brace member and a first notch on one side of the slot and a second notch on an opposite side of the slot, wherein the slot is v-shaped, with a mouth of the slot being wider than the width of a distal end of the slot, wherein sides of the stem and an underside of the top flange are adhesively bonded to facing surfaces of the brace-receiving portion; and a rectangular locking collar slidingly positioned around an end of the tee-shaped brace member, wherein opposite sides of the locking collar are received in the first and second notches in the brace-receiving portion on either side of the slot such that the interaction of the sides of the locking collar with the notches of the brace-receiving portion locks the stem of the tee-shaped brace member in the slot of the brace receiving portion.
