Bonnet mounting apparatus of agricultural work vehicle
A bonnet mounting apparatus of an agricultural work vehicle enables a bonnet that covers an engine compartment of an agricultural work vehicle to be opened upward. The bonnet mounting apparatus includes: a fastener on which a coupling protrusion is provided, and which is attached to the inside of one end portion of a bonnet; and a hinge on which a coupling recess, into which the coupling protrusion is inserted, is provided, and which is hingedly coupled to the upper end of a bonnet support at a vehicle body side so as to be rotatable upward and downward. According to the present invention, the bonnet is easily connected to the vehicle body by inserting the coupling protrusion of the bonnet into the coupling recess of the hinge at the vehicle body side.
1. A bonnet mounting apparatus of an agricultural work vehicle, the bonnet mounting apparatus comprising:
a fastener on which a coupling protrusion is provided, and which is attached to an inside of one end portion of a bonnet; and
a hinge on which a coupling recess is provided, and which is hingedly coupled to an upper end of a bonnet support at a vehicle body side so as to be rotatable upward and downward, thereby allowing the bonnet to be mounted by inserting the coupling protrusion of the bonnet into the coupling recess of the hinge at the vehicle body side,
wherein a latching fixing part is provided on a part of a circumference of the coupling protrusion, and a latching projection, which engages with the latching fixing part, is provided on the coupling recess,
wherein the latching projection is elastically moved outward when the coupling protrusion is inserted into the coupling recess, and
wherein an end part of the hinge, which is an opposite side of a portion hingedly coupled to the bonnet support, is fixed by a bolt to one side of the fastener.
2. The bonnet mounting apparatus according to claim 1 , wherein the coupling protrusion is formed in a triangular shape whose width tapers in a downward direction.
3. The bonnet mounting apparatus according to claim 1 , wherein ball grooves are provided on opposite sides of a neck portion of the coupling protrusion, and ball plungers are provided on the coupling recess, the ball plungers comprising: balls partially positioned in the ball grooves when the coupling protrusion is completely inserted into the coupling recess so as to prevent detachment of the coupling protrusion from the coupling recess; and springs for elastically supporting the balls.
