<p>The invention relates to a device (1) for a coupling an agricultural implement (3) to an agricultural tractor (2), in which the operation to release the coupling between the agricultural implement and the agricultural tractor can be easily implemented.</p><p><Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">When the coupling of the agricultural tractor and the agricultural implement is released, first, a control lever (12) of a coupling hook is slid upward against the urging force of a spring (13) until a second guide pin (23) reaches the lower end of a slit (33). Next, the control lever is turned forward around the second guide pin until a bent portion of the upper portion and the lower portion of the control lever comes into contact with a first guide pin (21). As a result, the rear end of a stopper (11) is retracted into a cavity (9) in the hook main body (10) of the device through a second opening (15) so as to slide to the coupling-ball-releasing position, and a groove (28) of the stopper is hooked to a hooking pin (22) so as to be fixed.</p> |
