Description

[Detailed Description of the Invention] The present invention provides a system in which the left and right axles, which are protruded from the transmission case, are separately connected to each other when driving in a normal field or on the road, where it is necessary to suppress rolling of the vehicle body in order to make it easier to maneuver. Moreover, it can be configured as a so-called two-wheel type with a pair of wheels mounted relatively apart, and it prevents the risk of overturning and when driving in wet fields where it is necessary to run over stumps to prevent the vehicle body from sinking. When traveling on intermediate ground such as ridges where it is necessary to prevent wheels from coming off, the walking system can be configured as a so-called one-wheel type in which both the left and right wheels or only one wheel are attached to one axle. Regarding type mobile agricultural machinery.

When the mobile agricultural machine mentioned above is made into a two-wheeled type, in order to make it easier to balance the operation by positioning the center of the body approximately in the center between the two wheels, it is necessary to make it small because it is a walking type. Because space for the wheels must be secured on both outsides of the transmission case, the transmission case is located approximately at the center of the vehicle body.

Therefore, if the transmission case is a fixed type, it becomes difficult to align the center of the wheel with the center of the vehicle body when the transmission case is a one-wheel type, and as a result, there is a problem that the left-right balance is lost and it becomes difficult to maneuver.

The present invention aims to solve the above-mentioned problems by configuring a transmission case with an axle protruding from the left and right sides so that its mounting position can be changed in the left-right direction of the vehicle body, and by changing the mounting position of the case, a pair of wheels can be moved. The vehicle is characterized by being configured to be switchable between a first state in which wheels are attached to each of the left and right protruding axles separately and relatively apart from each other, and a second state in which wheels are attached only to one of the axles. Specifically, since the mounting position of the transmission case is changed in the left-right direction of the vehicle body to make it into the second state, that is, the one-wheel type, it becomes easier to align the center of the wheel with the center of the vehicle body. , it becomes easier to maintain left and right balance, making it easier to maneuver.

Embodiments of the present invention will be described below based on illustrative drawings.

The walking binder includes a culm pulling device 1, a culm reaping device 2, and a device for transporting the culm from these 1 and 2 to one side of the vehicle body, located at a low front position of the wheeled traveling device. 3
, a working device 5 consisting of a device 4 for bundling and discharging a fixed amount of shell culms from the conveying device 3 is mounted, and an engine 6 for driving the traveling device and the working device 5 is mounted at a low position behind the traveling device. The working device 5 and the engine 6 are connected by a continuous frame 7, so that as the vehicle moves, the planted culms can be raised and harvested, and the cut culms can be bundled and released. It is.

When driving in normal fields or roads where the vehicle body does not sink, such as dry rice fields, the traveling device is a two-wheel type, and when driving on wet fields or on ridges, the vehicle body is driven over stumps to prevent the vehicle body from sinking. When traveling on intermediate ground, the traveling device is configured to switch to a one-wheel type.

That is, a transmission case 9 is interlocked with a transmission 8 which is interlocked with the engine 6, and the transmission case 9 has a short axle 10 protruding from the left side and a long axle 11 from the right side.

Output shafts 12 for the transmission case 9 are provided on both left and right sides of the transmission 8, and the transmission case 9 for the transmission 8 is connected to the transmission case 9.
The structure is such that the mounting position in the interlocking state can be changed in the left-right direction of the vehicle body.

When the transmission case 9 is installed on the right side of the transmission 8, the transmission case 9 is located at the center of the left and right sides of the vehicle body, and when the transmission case 9 is installed on the left side of the transmission 8, the transmission case 9 is located off to the left side of the vehicle body. The long axle 11 is located toward the center of the vehicle body, and the short axle 11 is located toward the left side of the vehicle body.

7. When the traveling device is a two-wheel type, a transmission case 9 is added to the right side of the transmission 8 as shown in FIG. 2A, and a pair of wheels 13 are added as shown in FIG. 3A.
．． 13 is attached to the short axle 10 via the extension axle 14, and the other is attached to the long axle 11.
3.13 are placed in a first state relatively apart via the transmission case 9.

When the traveling device is a one-wheel type, the transmission case 9 is attached to the left side of the transmission case 8, as shown in the opening in Figure 2, and the wheel 1 is attached as shown in the opening in Figure 3.
3, a wider wheel 15 or the pair of wheels 13.
13 are configured so that they are in the second state where they are added only to the long axle 11 located near the center of the vehicle body.

Each of the long and short axles 10 and 11 is provided with a clutch mechanism 16 that is operated separately, and when a two-wheel type vehicle is used, the vehicle direction is controlled by operating the clutch mechanism 16 on and off.

When the frame 7 is viewed from the side, each of the wheels 13.13
．． The frame 7 is curved upward to bypass the upper part of the wheel 15, so that the frame 7 does not become an obstacle when the wheel is attached or detached.

The installation position of the transmission case 9 can be changed by sliding the engine 6 to which the transmission case 9 is interlocked, as shown in FIG. 4A showing the fourth state and FIG. The transmission system may be simplified by configuring it to do so.
