Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a threshing and sorting device that is installed in a state in which the front end side is located on one side of a control section provided in a traveling machine body and close to the control section. The present invention relates to a sunshade mounting structure for a combine that is mounted on a traveling aircraft and that provides a sunshade for the control section.

[Conventional technology]

In the above combine harvester, conventionally, the awning support is composed of a vertical portion extending in the vertical direction of the machine at the rear end side of the awning, and a horizontal portion extending from the upper end of the vertical portion to the front side of the awning along the awning, By eliminating the presence of vertical support columns at the front end of the sunshade, the sunshade can be installed without obstructing visibility in front of the aircraft. In this case, the following disadvantages occurred.

[Problem that the invention attempts to solve]

Since the struts have a cantilevered structure, it is necessary to increase the size of the struts in order to provide the desired support strength.

The purpose of the present invention is to reduce the weight of the support column while suppressing the deterioration of forward visibility.

[Means to solve the problem]

The characteristic configuration of the present invention is that, in the combine awning mounting structure described above, a lateral end portion of the awning on the opposite side from the threshing sorting device side is connected to a first support provided upright in the frame portion of the traveling machine; A lateral end of the awning on the side of the threshing sorting device is connected to a second column located on the rear end side of the awning and erected at the upper end of the threshing sorting device, and the second column and the awning In between, there is provided a flexible portion that allows the second support and the sunshade to move relative to each other in the horizontal direction, and its functions and effects are as follows.

[Effect]

By erecting the second strut at the rear end of the awning, the degree to which the second strut obstructs forward vision is reduced compared to when the second strut is erected at the front end.

Even if the support at both ends of the awning by the first and second pillars is lighter and smaller than in the case of cantilever support,
It is possible to provide the necessary support strength to each of the first and second columns, and the length of the second column is shorter compared to that of installing the second column upright at the upper end of the threshing and sorting device. This makes it possible to provide the necessary support strength to the second column even if it is made light and small, and the flexible part absorbs the vibration difference between the threshing sorting device and the traveling machine, and rigidly connects the second column and the sunshade. To make it possible to give the second support pillar the necessary support strength even if it is made lighter and smaller than the previous support pillar.

[Effect of idea]

By suppressing the degree of deterioration of the forward visibility caused by the second pillar, the forward visibility can be made as good as possible, while supporting both ends of the awning, installing the second pillar at the upper end of the threshing and sorting device, and providing the above-mentioned flexibility. The effects of each part have made it possible to make the support column lighter and smaller, making it possible to reduce the weight and cost of the sunshade structure.

〔Example〕

As shown in FIG. 6, a threshing sorting device 4 is attached to a crawler-type traveling body equipped with a control section 2 having an awning 1 and a driving section 3, and the front end side of the threshing sorting device 4 is attached to the control section 2 on one side of the control section 2. At the same time, the threshing grain tank 5 is mounted so as to be located above the threshing sorting device 4 and the driving unit 3, and the planted grain culm is raked toward the rear of the machine body by the driving rotary reel 6. A reaping pretreatment device 7 for reaping and conveying the harvested grain culm to the rear of the machine body is connected to the front end of the traveling machine body so as to supply the entire harvested grain culm to the threshing chamber (not shown) of the threshing sorting device 4. The combine harvester has been configured.

As shown in FIGS. 3 and 4, the control section 2 includes, in addition to the sunshade 1 for the control section 2, a rear wall 8, a side wall 9 on the outside of the fuselage, a side wall 10 on the inside of the fuselage, and a control section. A blower device 11 and a fan 12 are provided at the front to form an air curtain to prevent dust from entering.

As shown in FIGS. 3 to 5, the sunshade 1 consists of a sunshade hood 1a and a hood frame 1b, and includes a frame portion 13 for attaching a driving step of the traveling aircraft and a frame portion 14 for attaching a driver's seat. The lateral ends of the canopy frame 1b on the outside of the fuselage body are connected by bolts to a pair of front and rear first columns 15, 15, respectively, which are erected separately, and threshing is carried out with the hood frame 1b positioned on the rear end side of the front end of the awning 1. The lateral end of the canopy frame 1b on the inside of the machine body is connected with a pin to one second support 16 erected at the upper end of the device 4, and the first support 15 and second support 16 connect the threshing and sorting device side. It is supported at both ends on the opposite side.

As shown in FIGS. 1 and 2, the receiving connecting portion 16 of the second support column 16 to the canopy frame 1b
a, and the receiving connection portion 16a of the top frame 1b.
A pin hole 18 provided in the mounting connection part 1c is formed so that the pin hole 18 which connects the mounting connection part 1c to the mounting connection part 1c is inserted therethrough, and the hole diameter is considerably larger than the outer diameter of the pin 17. , the second pillar is installed so as to absorb the difference between the vibration of the traveling machine transmitted to the first pillar 15 and the vibration of the threshing sorting device 4 transmitted to the second pillar 16.
It is configured to allow relative movement of the support column 16 and the sunshade 1 within a set range in the horizontal direction.

As shown in FIGS. 3 to 5, the rear wall 8 consists of a wall body 8a made of cloth and a shape-retaining frame 8b,
A shape-retaining frame 8b is bolted to the first pillar 15 on the rear side and the canopy frame 1b so as to be supported by these.

The side wall 9 includes a wall main body 9a made of cloth and a shape-retaining frame 9b.
A shape-retaining frame 9b is connected to the first pillar 15 on the rear side and the canopy frame 1b by bolts so as to be supported by these.

The side wall 10 is composed of a cloth wall main body 10a, a shape-retaining frame 10b, and a wall plate 10c connected to the shape-retaining frame 10a via a connecting plate 19.The wall main body 10a is attached to the canopy frame 1b, and A shape-retaining frame 10b is connected across the top frame 1b and the shape-retaining frame 8b, and is supported by the sunshade 1 and the rear wall 8.

[Another example]

A rubber joint may be used instead of the pin hole 18, and these are collectively referred to as the flexible portion 18.
