Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
A device for the fast changing of the operating method of field spraying units on wheels for spraying fertilizer and/or pesticides, comprising: a field spraying unit having at least one socket; a quick-acting coupling directly connected with the socket and including one coupling part which is a screw cap, said coupling being connected to said socket at said one coupling part; a universal nozzle and a prefilter carried by said one coupling part; at least two different second coupling parts for two different fluids, said two different coupling parts being alternately releasably connected with said one coupling part; and an attachment unit for fluid distribution connected with each said second coupling part, whereby a second coupling part for a first fluid may be rapidly swiched for a second coupling part for a second fluid.
Claim 2
Independent Claim
