Abstract

(57) [Summary] [Purpose] To secure a wide field of view for the operator in a combine equipped with a cabin type control unit. [Composition] A damper 17 is arranged at a lower end portion of a door body 14 to prevent the damper 17 from obstructing a driver's view.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine for harvesting and threshing, and more particularly to an arrangement structure of a damper for a cabin door in a combine.

[0002]

[Problems to be Solved by Prior Art and Invention]

 Generally, some combine harvesters of this type have a cabin-type control section with a cockpit inside, but this one requires the provision of a door that opens and closes the entrance and exit of the control section, as well as the door and the entrance and exit. It is desirable to install a damper for absorbing the shock caused by opening and closing between the parts. Therefore, in the past, a damper was provided on the upper end side of the door body, but in this case, there is a risk that the damper will be located near the driver's line of sight, which narrows the driver's view. That was the inconvenience.

[0003]

[Means for Solving the Problems]

 The present invention was devised with the object of providing an arrangement structure of a damper for a cabin door in a combine that can eliminate these drawbacks in view of the above-mentioned circumstances. In a combine that is equipped with a door body that can be opened and closed freely in the steering section of the cabin type, and a damper that is connected to the door body to absorb the shock caused by opening and closing, the damper is arranged at the lower end It is characterized by having been set up. Further, the present invention is capable of ensuring a wide field of view of the operator with this configuration.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a combine, and the combine 1 comprises a pretreatment unit 2 for cutting stems, a threshing unit 3 for threshing stems conveyed from the pretreatment unit 2, and a threshing unit 3. A post-processing unit 4 for discharging the culms conveyed from the container, a grain tank 5 for storing the grains selected by the threshing unit 3, and a control unit arranged in front of the grain tank 5. 6 and the like, all of which have the same basic configuration as conventional ones.

The control section 6 has a control seat 7 and a control panel 8 incorporated therein, and is configured to be movable up and down with respect to the machine body frame 1a. That is, a pair of left and right guide rails 9 are provided upright on the rear surface of the control section 6 on the machine frame 1a, while guide rollers 10 fitted to the guide rails 9 are provided on the rear surface of the control section 6 to control the control section. 6 can be moved up and down along the guide rails 9, but a hydraulic cylinder 11 for hydraulically raising and lowering the control section 6 is interposed between the machine body frame 1a and the rear surface of the control section 6. Reference numeral 12 is a stopper mechanism that regulates the lowering of the control portion 6 based on the operation of the lever 13.

By the way, the control section 6 is formed into a box-shaped cabin to house the control seat 7 and the control panel 8, and the doorway 6 a formed on the right side surface of the control section 6 has A door body 14 whose rear end is hinged so as to be openable and closable is provided, and a step 15 having a tread surface 15a located below the doorway 6a is provided at the bottom of the control section 6. The door body 14 is formed to extend downwardly below the floor surface FL of the control portion 6, while a recess 6b into which the downward extension portion of the door body 14 is laterally fitted is formed in the lower part of the doorway 6a. ing. That is, when the door body 14 is opened, the tread surface 15a of the step 15 is exposed from the inside of the control portion 6 through the recess 6b.

Further, 16 is an airtight material that is attached to the inside of the recess 6 b, and the airtight material 16 elastically abuts the inner surface of the downward extension portion of the door body 14 when the door body 14 is closed. By doing so, the airtightness of the control section 6 is ensured.

Furthermore, 17 is a damper, and the damper 17 is interposed between the door 6 a of the control section 6 and the door body 14 so that the shock caused by opening and closing the door body 14 One end is connected to the first bracket 18 fixed to the lower end surface of the door body 14, while the other end is located below the door body 14 of the control section 6. It is connected to a second bracket 19 protruding from the bottom surface. That is, the damper 17 is arranged at a position below the door body 14 which is out of sight of the operator. Furthermore, the extension limit of the damper 17 is set so that it can also be used as a stopper for restricting the opening of the door body 14 more than necessary (90 ° or more).

In the embodiment of the present invention constructed as described above, the damper 17 is provided on the lower surface of the door body 14 with the first bracket 18 and on the bottom surface of the control portion 6 so as to be located below the door body 14. Since it is interposed between the second bracket 19 and the second bracket 19, it is arranged below the door body 14. Therefore, unlike the conventional case where the damper 17 is provided on the upper end side of the door body 14, there is no inconvenience that the damper 17 is located near the driver's line of sight. It can be secured to improve safety.

Moreover, since the damper 17 is arranged below the door body 14, there is no inconvenience that the damper 17 is projected laterally to increase the body width.

Further, since the extension limit of the damper 17 is set to control the opening of the door body 14 more than necessary, it is possible to reduce the number of parts without providing a separate stopper.

[Operation effect]

 In summary, since the present invention is constructed as described above, the door body provided in the steering section of the cabin type is connected with the damper that absorbs the shock caused by the opening and closing of the door body. Since the damper is arranged at the lower end of the door body, the damper is located near the operator's line of sight, unlike the conventional damper provided at the upper end side of the door body. As a result, it is possible to secure a wide field of view for the driver and significantly improve safety.
