Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called riding combine harvester, which is equipped with a reaping device at the front of the machine so that it can be raised and lowered, and a part of the machine is equipped with an operation box and a pilot's seat.

As this type of riding combine harvester, for example,
There are proposals such as those published in Publication No. 3932. The outline of the above proposal consists of a reaping device that reaps the grain, a conveyance device that conveys the grain that has been cut by the reaping device, a threshing device that threshes the grain that has been conveyed by the conveyance device, and a cockpit where the worker sits. It has a structure that allows it to be attached directly to the machine base. For this reason, when attaching the cockpit to the aircraft base, the support members that support the cockpit must be assembled directly from the aircraft base, which requires many parts and complicates the configuration of the aircraft base. There were problems in that the number of assembly steps increased and the weight of the machine increased.This invention was made to improve the above problems, and its purpose was to use a threshing device with a strong framework. The purpose of the present invention is to provide a passenger combine harvester that has a simple structure and can reduce assembly man-hours by attaching a pilot's seat, as well as reducing the weight of the machine.

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

In the figure, reference numeral 1 indicates a reaping device in a combine harvester, which is equipped with a cutting blade 3, a weed cutting blade 5, and the like.

7 is a grain transfer device equipped with a lifting lug 9 for lifting and transporting the grain cut by the cutting blade 3;
The tip side of the hardwood grains is transferred into the threshing device 11.

13 is the threshing chain; 15, IT is the narrow guide.

Reference numeral 19 indicates a control section, which is composed of an operation box 21 equipped with various control panels, a control seat 23, and the like.

Reference numeral 25 denotes a hydraulic control lever for raising and lowering the mowing device 1, and is arranged on one side of the pilot's seat 23.

27 indicates the seat for guarding the operator and the cockpit 2.
The guard member that supports 3 is formed by appropriately bending a pipe member or the like.

Reference numerals 29 and 31 indicate support frames for the cockpit 23 that are integrally provided with the guard member 27, and the support frames 2 on the 1st side are
9 is fixedly attached to the machine frame of the threshing device 11, and the support frame 31 at the end of the pond is attached to the toothpick tube 35 via a bracket 33.

The support frame 29 protrudes from the front corner of the highly rigid threshing device 11, and the support frame 31 is provided in a direction perpendicular to the support frame 29. As shown in the figure, it has a T-shape.Denoted at 37 is a front frame fixed to the support frame 29, extending forward from the support frame 29. The lower end portion is fixed to a step frame receiver 39.

The step frame receiver 39 is attached to a gear box 45 of a traveling device 43 mounted on a machine base 41 via a bracket 47. 49 is a step frame supported by the step frame receiver 39 and the machine base 41,
A step 51 is attached to the top surface.

Note that the aforementioned operation box 211 is arranged at the front position of the step frame 49. Reference numeral 53 denotes a supply adjustment village for adjusting the supply length (feeding depth) of the grain tip side when feeding the grain tip side into the threshing device 11, which includes one part of the reaping device and an operation box. It is located between 21 and 21.

Reference numeral 56 denotes a support member that supports the base of the supply adjustment village 53 via a support shaft 57 in a vertically movable manner, and is connected to the support frame 2.
It is fixedly attached to the front part of 9.

The supply regulating punch 53 is provided extending from the base in the direction of the reaping device 1, and its tip is supported by the front frame 37. 59 is the change lever, Hasumura 61
It is interlocked and connected to the gear box 45 via.

The operating fulcrum of the gear box 45 in this change lever 59 is provided on the step frame 49. In particular, in this invention, the support frame 29 for supporting the cockpit 23 is attached to the corner of the machine frame of the thresher 11, and the support frame 29 is attached to a tin grain cylinder 35 integrally provided with the thresher 11. Since the support structure of the cockpit 23 is extremely simple and stable support is possible, the step frame 49 is supported by a step frame support 39 extending from the gear box 45. Since the operation box 21 is disposed at the front of this step frame 49, the frame structure is simplified and strengthened.Furthermore, the support frame 29 of the cockpit 23 is also used as a support member for the supply adjustment village 53. At the same time, the step frame 49 "front frame 37
Since the change lever 59 and its actuating part are supported using a As is clear from the above, according to the configuration of this invention, the frame supporting the cockpit is supported on the threshing device side. No need to assemble.

Therefore, the configuration of the machine base becomes simple and it is also possible to reduce the weight of the machine. Since the support frame is connected to the step frame on the machine base side via the front frame, the support structure of the support frame can be made strong even if the support frame is supported on the threshing device side. It is also possible to subassembly the support frame and the step frame via the front frame, making assembly easier.
