SIDE BOOM SHOCK-ABSORBER OF PESTICIDE APPLICATOR

摘要

PROBLEM TO BE SOLVED: To solve the problem that an extending/retracting cylinder cannot be protected in a conventional pesticide applicator because a shock-absorber activated when the conventional applicator is not provided with a side boom swings forward in relation to the advancing direction and a shock-absorber is installed at a position other than an operation system of the cylinder for opening and closing the side boom. SOLUTION: The extending/retracting cylinder 6 for opening and closing is interposed between a center boom 3 provided in the front part of a tractor body 1 and a side boom 5 freely foldably installed on the end thereof. The cylinder 6 has one swing arm 8 provided with a shock-absorbing spring 9 connected to the side boom 5 and the other support member 10 provided with an elastic shock-absorbing member 11 connected to a lift link 2.
