Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine cabin having a control unit therein.

[0002]

[Prior Art]

 Conventionally, a self-propelled combine in which a control section is provided in a cabin is known and disclosed by Jpn. Pat. Appln. KOKAI No. 3-130797, but the drawings described in this publication may be referred to. As can be seen, from the positional relationship between the control panel and the cutting board of the cutting section, it is difficult for the driver to visually check the weeding condition of the planted culm from the control section during the cutting operation, and the driver usually leans forward. . Moreover, if the control part is installed in the cabin, the driver cannot lean out because of the windshield, and the driver has to take his intuition into consideration.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention makes it easier for the driver to work easily by visually observing the weeding condition of the swarding board at the time of mowing work in the combine as described above, especially in the combine provided with the control section in the cabin. It was devised to do so.

[0004]

[Means for Solving the Problems]

 As described in the preceding paragraph, the present invention has a threshing section, an engine and a grain accommodating section mounted on the traveling device and a mowing section provided on the front side of the cabin so that the driver can easily perform the work in the mowing operation. In a combine equipped with a control unit inside, the cabin can be rotated back and forth with the lower part of the front end as a fulcrum so that it can be tilted forward and backward, and the raising and lowering operation of the mowing unit and the attitude changing operation of the cabin are performed. It has a structure in which and are linked together.

[0005]

[Action]

 With this configuration, when performing the mowing work by operating the mowing clutch and the traveling clutch, the mowing part is lowered to move to the mowing posture, and at the same time as this operation, the cabin with its lower front end as a fulcrum is used as the fulcrum. With the leaning forward leaning posture, the driver can visually check the weeding condition of the grass plate in the mowing section through the windshield from the control section in the cabin, and can easily perform the mowing work and raise the mowing section. Then, the cabin returns to its original posture from the forward leaning posture and becomes a safe driving posture at once.

[0006]

【Example】

 The combine cabin according to the present invention will be described below with reference to the accompanying drawings. The combine cabin has a threshing section (A) on the left side of a machine stand (4) mounted on a crawl type traveling device (1). ) Is installed, and on the right side, the grain storage unit (2), which is the grain tank that stores the grains that have been grain-processed by the threshing unit (A) and that has been wind-selected, and the engine for driving (E) The control section (C) is provided on the front side of the grain accommodating section (2), and the cutting section (B) is arranged from the front side of the threshing section (A) to the front side of the control section (C). As the machine progresses, the planted culms are cut, the grain is picked, and the grains are stored in the grain accommodating unit (2). After threshing, the straw is dropped to the rear of the machine and the grains are accommodated. The grains stored in the section (2) are lifted by the lifting cylinder (5), passed on to the discharge auger (6), and taken out to an appropriate place. It has become way.

The operation section (C) including each operation lever such as a mowing clutch lever, a traveling clutch lever, a mowing section elevating lever, and a driver's seat is installed in the cabin (3), and the cabin (3) thereof is provided. 3) is a frame-structured frame in which windshields (7) are provided on the front side and plate bodies with transparent parts are formed on the rear side and the left side, respectively, and the right side (elevating side of the driver). A door (8) is attached to the door so that it can be opened and closed, and a ceiling plate is stretched over the upper surface.

[0008] The cabin (3) is normally rotated by a hydraulic cylinder device (10) that is rotatable forward and backward around a support shaft (9) horizontally extending in the lower part of the front end of the cabin (3) and lifts the rear part. It is constructed so that it can be changed from an upright posture to a forward leaning posture (a), and the mowing section (B) is moved up and down by a hydraulic cylinder device (11) like the conventional one to obtain a mowing position (b). The running posture (d) is changed.

Further, the hydraulic cylinder device (10) for moving the cabin (3) from the upright posture to the forward leaning posture (a) and the mowing section (B) are moved up and down to perform the mowing posture (b) and the running posture ( The hydraulic cylinder device (11) for changing operation to (d) is connected to the valve (14) by the respective pressure oil pipes (12) and (13), and the solenoid for changing the attitude of the cabin and the mowing unit provided in the valve (14). A lifting solenoid is provided in the control section (C) and is electrically connected to a mowing section lifting lever to operate each hydraulic cylinder device (10) (11) at the same time by operating the mowing section lifting lever. When lowering the mowing unit (B) to the mowing position (b), changing the cabin (3) to the forward leaning position (a), and raising the mowing unit (B) to the running position (d). Returns the cabin (3) to its normal upright position It is designed to work together as if to do.

A boot (16) is provided between the bottom of the cabin (3) and the step (15) to prevent dust from entering when the cabin (3) is tilted forward (a). I try to prevent it.

Therefore, when performing the mowing work by operating the mowing clutch and the traveling clutch, the operation is performed by operating the mowing section elevating lever to lower the mowing section (B) to the mowing position (b). At the same time, the cabin (3) takes a forward leaning forward posture (a) with the support shaft (9) at the lower front end as a fulcrum, and the driver moves from the control section (C) in the cabin (3) to the windshield (7). ), The weeding condition of the grass board in the mowing section (B) can be visually observed, and when the mowing section (B) is raised to the running posture (d), the cabin (3) is moved from the forward leaning posture (a) to the original posture (a). Return to your posture.

A limit switch is provided in the mowing clutch lever portion of the mowing clutch so that the electric circuit to the cabin posture changing solenoid provided in the valve (14) is cut off when the mowing clutch is “disengaged”. Therefore, the cabin (3) cannot take the forward leaning posture (a) unless the reaping clutch is "on".

[0013]

[Effect of the device]

 As described above, the combine cabin according to the present invention has the threshing section (A), the engine (E) and the grain accommodating section (2) mounted on the traveling device (1) and the cutting section (B) on the front side. In a combine in which a control section (C) is provided in a cabin (3) provided, the cabin (3) can be pivoted back and forth with its lower front end as a fulcrum and can be changed to a forward leaning posture (a). Since the raising / lowering operation of the mowing unit (B) and the posture changing operation of the cabin (3) are interlocked with each other, the mowing operation is performed when the mowing clutch and the traveling clutch are engaged. If B) is lowered and moved to the cutting position (b), at the same time as this operation, the cabin (3) becomes the forward leaning position (a) with the front lower part of the fulcrum as the fulcrum, and the driver Is the control part in the cabin (3) ( ) Makes it possible to visually check the weeding condition of the grass plate in the mowing section (B) through the windshield (7), and the mowing operation can be performed easily. When the mowing section (B) is raised, the cabin (3) is moved to the front. The tilted posture (a) returns to the original state, and the vehicle is ready for safe driving. Therefore, it is especially easy to visually check the weeding condition of the swarding board at the time of cutting work at the combine where the control section (C) is installed in the cabin (3). As a result, the driver will be able to work more easily while ensuring safety while driving.
