Description

[Detailed description of the invention] The present invention is designed to be mounted on the machine frame so that it can be switched freely between a ground contacting posture and a non-grounding posture, in order to support the aircraft in a stable position on the ground in cooperation with the traveling wheels when it is in a stopped state. The present invention relates to a technique for preventing forgetting to close the stand when driving an aircraft by interlocking and connecting a stand that has been moved and a latch lever that moves, and associating operation of the latch lever that moves and operation of raising and lowering the stand.

The stand and the running latch lever are interlocked, and the running latch lever operation is associated with the stand raising and lowering operation.
Japanese Utility Model Publication No. 39-13419 discloses a technique for preventing forgetting to close the stand when driving the aircraft.

This structure uses engine power to move the stand up and down, and specifically, the clutch that transmits the power from the engine to the stand and the transmission system on the downstream side are connected to the clutch that transmits the power from the engine to the stand. A latch is provided that can be selectively switched between a state in which the rotation is transmitted in a forward rotation state and a state in which it is transmitted in a reverse rotation state, and both clutches and a running latch lever are interlocked and connected,
A clutch for transmitting power from the engine to the stand can be operated at the same time as the latch is turned off by operating the latch lever backward, and the latch lever is moved when the latch is disengaged. By operating the latch in the left-right direction, the stand can be raised or lowered by operating a latch that transmits the power to the stand in the forward rotation state or in the reverse rotation state.

However, when the stand is in use, the engine is often not started, such as when changing wheels or replacing a rotary device, so with the conventional structure described above, the engine must be started every time. However, it becomes troublesome to take the stand in and out.

Also, when driving the aircraft while using the stand,
There was a drawback that sometimes people forgot to operate the running latch lever left and right to raise the stand, and then operated the running latch forward and engaged it, damaging the stand. .

In view of the above points, the present invention aims to provide a mobile agricultural machine with a ground-contacting stand, in which the stand can be easily put in and taken out, and the stand can be prevented from being forgotten when the machine is running.

It is installed so that it can freely swing and swing freely between the supporting ground action position and non-action position.

Reference numeral 2 denotes an operating rod that changes the posture of the stand 1 by moving along its longitudinal direction, and this is located near the grip portion of the steering handle 11 whose manual operation grip portion 2a extends rearward. It is placed in the state where it is located.

Reference numeral 4 denotes a tension arm 3a of a clutch 3 for stopping the aircraft traveling using a belt tension clutch, which is interposed in the transmission system from the engine 9 to the transmission case 8, and a clutch operating lever 12 attached to the grip of the operating handle 11. This rod is arranged in an attitude substantially parallel to the operating rod 2.

In this embodiment, a buzzer 5, which is an example of an alarm device, is provided, and a linkage mechanism 6 is provided between the buzzer 5 and the clutch 3.

This linking mechanism 6 has one end attached to the grip portion 2 of the operating rod 2.
The arm 13, which is slidably and pivotably connected to the fuselage at all times and is slidably engaged near a, is connected to the rod 4 of the clutch 3 at its other end, and the operating rod When the rod 4 moves in the clutch engagement direction with the stand 1 in the operating position where the stand 1 is placed in the ground contact position, the rod 4 is pressed by the arm 13 that swings accordingly, and performs an engagement operation on the clutch 3. A switch 14 is attached to the operating rod 2 for the buzzer 5 which becomes energized before the operation is completed, so that when the clutch 3 is engaged and operated while the stand 1 is in the grounding posture, the clutch 3 is fully engaged and operated. When the stand 1 is operated to the ground contact position with the clutch 3 engaged and in the operating position, the buzzer 5 is activated before the stand 2 switches to the ground contact position. He is trying to activate the system.

15 is a tilling rotary arranged behind the wheel 7, and 16 is a pitch for attaching this tilling rotary 15 to the mission case 8.

This hitch 16, as shown in FIG.
A box-shaped second hit member 16B that can be fitted and attached to and separated from the first hit member 16A is fixed to the second hit member 6A. A projection 18 for maintaining the fitted state that can be freely engaged and disengaged from the engagement hole 17... and a manual operation lever 19 for engaging and disengaging the protrusion 18 via the cam mechanism C.
It is composed of the following.

Further, in this cultivator, a buzzer 5' other than the one described above is provided, and when the second hit member 16B is fitted into the first hit member 16A, A normally open contact is provided with a contact member 20 that moves when pressed by the member 16B, and is switched to an energized state when the grounding member 20 starts moving as the two hitch members 16A and 16B start to fit together; The first hit member 16 connects the switch 21 for the buzzer 5', which is connected in series with a normally closed contact that switches to a non-energized state upon completion of mating.
Attach it to A and hold both hitch members 16A.

When the fitted state of 16B is incomplete, switch 2
After the first normally open contact closes, if the normally closed contact does not open, the buzzer 5' is activated to notify the operator of this.

Incidentally, both the buzzers 5 and 5' may be configured to have a single buzzer.

In summary, the mobile agricultural machine with a grounding stand according to the present invention has an operating rod 2 with a grip part 2a for artificially switching the stand 1 between a grounding position and a non-grounding position, and a clutch 3 for stopping the machine body for turning on and off. In addition to arranging the rods 4 in parallel, 1. Between these two rods 2 and 4, when the clutch 3 is engaged and operated while the stand 1 is in the ground contacting position, the stand operating rod 2 is automatically switched to the non-working position, or the switching operation is performed. A linking mechanism 6 is provided to operate a notification device 5 for notifying the necessity, and one end of this linking mechanism 6 is interlockingly connected to the clutch 3 operating rod 4, and the other end is connected to the stand 1 operating rod 2. Since it is characterized by being composed of the arm 13 which is always in an engaged state, it has the following advantages.
