Abstract

PURPOSE:To prevent a mobile car body from turning over, etc., by operating a supporting device for supporting a load of a lawn container on the ground surface when the posture of the lawn container lifted to the topmost position or its vicinity is changed into a lawn discharging state. CONSTITUTION:When a lawn container 14 is lifted, lower links 20 are lifted and rotated and arms 26 can be moved through interlocking rods 28. When the container 14 is lifted to the topmost position or its vicinity, ground contact units 27 are brought into contact with the ground surface. Thereby, the car body 1 is kept in a stable state even if the lawn container is tilted to a discharge posture.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting / lowering stabilizer for a lawn container of a riding lawn mower.

[0002]

2. Description of the Related Art Conventionally, in a riding lawn mower in which a turf container is vertically movable on the riding vehicle body side, a means for supporting the turf container on the ground side is formed separately from a lifting mechanism for the turf container. , Was to activate the support mechanism for the turf container before it was raised.

[0003]

SUMMARY OF THE INVENTION According to the present invention, when a turf container is raised, a raising / lowering mechanism is constructed so that it does not work on the side where the balance fluctuation of the traveling vehicle body is bad, and the turf container is raised. At that time, it should be taken into consideration that if a road surface support device for a container is provided as in the prior art, it will be an obstacle to traveling, and the operation of the special support device of the prior art is troublesome and complicated. There was a drawback.

[0004]

According to the present invention, in order to solve the above-mentioned problems of the conventional type apparatus, the lawn mowing apparatus 10 is mounted on the riding vehicle body 1 through the elevating link mechanism 18, and In a riding-type lawn mower that conveys and stores the lawn mowed by the lawn mowing device 10 in a lawn container 14 provided on the vehicle body side, the lawn housed in the lawn container 14 is lifted up when ejected to maintain a posture. An operating mechanism for raising and lowering or changing the posture for changing the discharge state and a supporting device 24 for supporting the load of the turf container 14 on the road side are interlocked so that the supporting device 24 is grounded at the time of discharging the turf. It was a lifting and lowering stabilization device for the turf container of the riding lawn mower.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 is a riding type vehicle body,
It has a pair of left and right driving front wheels 2 for steering and a pair of left and right rear wheels 3, a riding floor 4 is stretched on the front side, and a control frame 5 projecting upward is provided at the center of the left and right sides of the riding frame 4 and its upper side. A steering wheel 6 is provided on the rear side, and a steering seat 7 is mounted on the rear part and an engine covered with a hood 8 is mounted on the rear side. Reference numeral 9 is a mission case that also serves as a vehicle body frame.

Reference numeral 10 denotes a lawnmower, which has a rotary shaft vertically supported inside a lawn mowing case 11 having a shape in which a wide bowl is laid down on the left and right sides, and a rotary blade is fixed to this. The lawnmower is suspended by a lifting link mechanism 12 so as to be vertically movable. Numeral 13 is a column that is erected on the left and right sides of the rear portion of the cockpit 7 of the traveling vehicle body 1. Reference numeral 14 is a turf container, which is formed in a box having a turf discharge port 16 provided with an opening / closing lid 15 which is provided in a posture in which the upper part is pivotally supported on the rear side and is always hung.

Reference numeral 17 is an elevating mechanism for moving the turf container 14 up and down. The upper link 19 operated by a hydraulic device 18 and the lower link 20 which is vertically swingable are pivotally attached to the support column 13 so as to swing. Both links on the moving front side are pivotally connected by a receiving frame 21 so that the receiving frame 21 can move up and down while maintaining a predetermined posture. Then, the rear side of the turf container 14 is attached to the receiving frame 21 via an arm 22 whose lower side is pivotally attached, and further the turf housing is placed between the receiving frame 21 and the turf container 14 in a turf discharging posture. A posture changing hydraulic device 23 for inclining the container so that the rear side is directed to the lower side is interposed.

Reference numeral 24 denotes a support device, which is constructed for the purpose of preventing the balance of the traveling vehicle body 1 from being lost when the posture of the turf container 14 for discharging the turf inside is changed. A grounding member 27 is attached to an arm 26 that is pivotally moved (a) at a position slightly apart from the base end side of the bracket 25 and pivots up and down. The lower link 20 is connected to the lower link 20 by an interlocking rod 28, and the grounding body 27 is movable to the grounding point of the wheel 2 or the wheel 3 when the lifting mechanism 17 is operated to the uppermost position or a position close to the uppermost position. is doing. That is, the grounding member 27 is configured not to be grounded to the road surface unless the grass container 14 is near the uppermost position where the grass container 14 is discharged, and is never grounded while climbing.

As shown in another embodiment of FIG. 5, the turf container 1
A member for changing the posture on the 4 side, for example, the arm 2 in the embodiment.
2 and the arm 26 on the side of the grounding body 27 may be linked by a wire-29. Reference numeral 30 in the drawings of the embodiment is a suction / conveyance fan for sucking up the grass cut by the lawn mowing device 10 and flipping it up, and the discharge port of the flip-up cylinder 31 and the lawn container 14 are concerned. In the lawn mowing state in which the container 14 is lowered, they are in communication with each other.

To explain the operation in the above example, in the lawn mowing work state, the lawn container 14 is in the state shown in FIG. 2 and the raising / lowering mechanism 17 is lowered, so that the lower link 20 interlocks. The arm 26 is swung up via the rod 28, and the grounding body 27 is held at a height that does not interfere with traveling. Next, when the turf container 14 is filled with turf and discharged, a transportation vehicle such as a truck is placed behind the vehicle body 1 and the turf container 14 is raised as shown in FIG. At this time, the arm 26 is gradually moved through the interlocking rod 28 by the upward rotation of the lower link 20, and the grounding body 27 comes into contact with the ground when the container 14 reaches the uppermost position. Therefore, even if the turf container 14 is tilted to the state of the phantom line in the next discharging posture and the balance is moved to the rear side, the vehicle body 1 is held in a stable state by the grounding body 27, so that the front side of the vehicle body 1 is The turf discharge work can be performed with peace of mind without the unexpected situation of surfacing.

As shown in FIG. 4, the arm 26 is constantly urged to the swing-up side by the spring 32, and the interlocking rod 28
If the arm 26 is lowered by the cam link rod 33 only near the uppermost position when the arm is pulled up by the link 20, the grounding body 27 is lowered and grounded at a necessary time, which is extremely convenient. ..

[0012]

According to the present invention, the turf container 14 is raised to or near the uppermost position and the container 14 is raised.
When changing the posture of the container to the turf discharge state, the container 14
Since the support device 24 works to support the load of
Stable turf discharge work can be performed without a situation in which the traveling vehicle body 1 loses balance.
