Description

[Detailed description of the invention] The present invention has a structure in which the working device is detachably attached to the traveling machine base, and in the installed state, the working device and the driving part attached to the traveling machine base are connected by a belt transmission with a tension clutch. The present invention relates to a mobile agricultural machine configured to be interlocked and connected by a device.

Conventionally, in the mobile agricultural machinery described above, when loading and unloading working equipment such as threshing equipment from the traveling machine platform, it is necessary to attach and detach the belt of the transmission device, which makes loading and unloading the working equipment troublesome. I was getting used to it.

In view of the above circumstances, the present invention aims to facilitate loading and unloading of working equipment by eliminating the need for special belt attachment/detaching work.

Next, embodiments of the present invention will be described with reference to illustrative drawings.

A threshing sorting device 5 is mounted on a walking type traveling machine platform 4 equipped with a driving unit 1, a crawler traveling device 2, and a control handle 3 so as to be able to be loaded and unloaded freely, and a device for collecting grains from the threshing sorting device 5 is installed. A pedestal 7 for the paddy bag 6 is provided, and the configuration is such that the grain culm is supplied to the feed chain 9 from the grain culm supply table 8 disposed above the driving unit 1, and the threshed waste straw is carried outside the machine by the conveying device 10. It is configured to emit. The driving unit 1 and the threshing sorting device 5 are interlocked via a belt transmission device with a tension clutch as described below.
That is, a pulley 14 for driving the threshing and sorting device is provided on the input shaft 13 of the gear transmission 12 for the crawler traveling device 2, which is transmitted to the output shaft 11 of the driving unit 1, and the first processed material of the threshing and sorting device 5 is input pulley 15 of the screw conveyor for collection;
A transmission belt 17 is wound around the input pulley 16 and the drive pulley 14 of the second screw conveyor for collecting processed material, and the tension pulley 19 operated by an arm 18 that can be switched and oscillated in an unstable manner is connected to the belt. 17, and a tension clutch is configured to freely drive and stop the threshing and sorting device 5.

The leg portions 20 of the threshing sorting device 5 are attached to the machine stand 4.
It is configured so that it can be inserted into a recessed mounting portion 21 formed in the body and can be removed by sliding it toward the front of the fuselage.
On the other hand, the input shaft 13 of the gear transmission
The threshing sorting device includes a mechanism that protrudes from the front of the machine body and holds the belt 17 in a non-wrapped state with respect to the drive pulley 14 in conjunction with the cutting operation of the tension clutch as described later in the axial direction. The belt 1 is attached to the belt 5 and is held by a holding mechanism as the threshing sorting device 5 slides on the machine base 4.
7 is configured to be detached from the drive pulley 14 or inserted into a position where it can be wrapped around the drive pulley 14, and the configuration will be described in detail below.

That is, in configuring the belt holding mechanism,
As shown in FIG. 4, the belt holding arm 22 is pivoted to the threshing sorting device 5 so as to be swingable about an axis _P2 different from the swing axis _P1 of the tension pulley operating arm 18. , the handle 18 is inserted into the elongated hole 23 formed in the belt holding arm 22.
A fixed pin 24 is loosely fitted into the arm 22 so that the arm 22 is swung in conjunction with the swiveling operation of the handle 18. Then, two clamping members 22a and 22b are attached to the arm 22, and another clamping member 25 is fixed to the threshing sorting device 5, and as shown in FIG. 3B, when the tension clutch is in the disengaged state, , the belt 17 is configured to be held at two locations by cooperation of one of the clamping members 22a attached to the arm and the fixed clamping member 25, and cooperation of the other clamping member 22b and the tension pulley 19, and the arm 2
2, the clamping member 22b of the arm first
The belt 17 is held by the tension pulley 19 and the arm 22 swings, and the belt 17 is pushed toward the drive pulley 14 and expanded in diameter, and the belt 17 is held against the drive pulley 4 by the subsequent swinging of the arm 22. The belt 17 is configured to be in a wrapped state and come into contact with a stopper 26 attached to the handle 18, and finally to be held by the clamping member 22a of the arm and the fixed clamping member 25.

In addition, various modifications can be made to configure the belt holding mechanism, such as omitting the stopper 26, making the stopper 26 into a curved rail shape, or changing the clamping configuration or the linking configuration with the handle 18. It is.

Further, the belt holding mechanism may be provided on the traveling machine stand 4 side, and in that case, the target pulley to be brought into the above-mentioned non-wrapping state is the one on the threshing sorting device 5 side.

In addition to the threshing and sorting device 5, there are various other working devices mounted on the traveling machine stand, such as a grass cutter and a tiller.

In summary, the present invention provides the mobile agricultural machine described at the beginning with a first arm 22 that extends with one end toward the slack side of the belt 17 of the belt transmission device and with the other end toward the tension side. and a second arm 18 equipped with a tension pulley 19 as a member constituting the tension clutch, which is one of the pair of pulleys on which the belt 17 is stretched, and is removed from the belt 17 when the working device 5 is attached or detached. The shaft center of the pulley 14 to be separated near the rotational support shaft 13
The first _{and second}
Each of the free ends of the arms 22 and 18 is extended close to the outer periphery of the pulley 14 to interlock the swinging of the first and second arms 22 and 18, and the one end side of the first arm 22 is A first clamping member 22b is provided which clamps the belt 17 with the tension pulley 19 and expands the diameter of the belt portion wound around the pulley 14 when the tension clutch is operated in the cutting direction. A second clamping member 22a is provided on the other end side of the first arm 22 to clamp the belt 17 between it and a fixed clamping member 25 fixed to the swinging end of the first arm 22. 4 and the working device 5, the pulley 14 is attached to one of the working device 5,
Since it is characterized in that other members are attached to the other side, the following effects are produced.

That is, when the tension clutch is operated in the cutting direction, the belt 17 wound around the pulley 14 to be removed is held with its diameter expanded, so the working device 5 is slid in the direction of the rotation axis of the pulley 14. will be able to leave. Therefore,
If the tension clutch is in the disengaged state, the working device 5 can be loaded and unloaded without any special attachment/detachment work to the belt 17.
Since the tension clutch is naturally in the disengaged state when loading and unloading the work device 5, the work device 5 can be loaded and unloaded easily and quickly without any operation or consideration required for attaching or detaching the belt 17. Ta.
