Field of the Invention The present invention relates to a threshing device mounted on a combine, and more specifically, a horizontal axis of a diffusing cylinder that gives a loosening action to a processed material discharged from a dust port at the rear end of a handling chamber. The present invention relates to a threshing device that is rotatably driven around the threshing case and has a dust removal fan forcibly discharging dust from inside the threshing case at the rear of the diffusion cylinder so as to be rotatably driven in the threshing case. .

For example, as disclosed in Japanese Patent Application Laid-Open No. 3-244315, fine dust and dust generated from a processed material that has been disentangled by a diffusion cylinder, or straw dust blown up by Karafu wind in a sorting device. It is known that dust and the like are discharged to the outside of the machine by a dust-discharging fan constituted by a cross-flow fan.

目的とする。By the way, in the above-mentioned conventional structure, although there is no particular problem in discharging fine dust and debris, the generation of debris increases when the amount of processed material increases. At the same time, relatively large straw scraps loosened by the diffusion cylinder may also be sucked by the dust exhaust fan and discharged outside. However, since relatively large straw dust is difficult to be carried by the exhaust air from the dust exhaust fan as described above, there is a possibility that it may adhere to a place where the exhaust air stagnates, for example, a pivotal support location of the rotating shaft of the dust exhaust fan. Is high, which may cause stray dust or the like to wind around the rotary shaft of the dust-exhaust fan, hinder the rotation of the dust-exhaust fan, or break the blades of the dust-exhaust fan made of a thin piece member. It was expensive. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a threshing device capable of preventing relatively large straw dust or the like from being sucked and discharged by a dust exhaust fan.

かかる特徴構成による作用・効果は次の通りである。In order to achieve the above-mentioned object, a threshing device according to the present invention has a diffusing cylinder which laterally disperses a processed material discharged from a dust outlet at the rear end of a handling chamber. Along with being rotatably driven around a shaft in a threshing case, a dust removal fan forcibly discharging dust from the threshing case at the rear of the diffusion cylinder is rotatably disposed in the threshing case, It is characterized in that a horizontal rod that obstructs the movement of dust to the dust exhaust fan is provided along the horizontal direction at an intermediate portion between the diffusion cylinder and the dust exhaust fan.
The operation and effect of this characteristic configuration are as follows.

There is a high possibility of colliding with a horizontal rod when moving while floating behind the diffusion cylinder, and the collision causes the straw dust to fall off the suction air passage of the dust exhaust fan and fall downward. . Further, by installing the horizontal rod between the machine walls of the threshing device, it can also be used as a reinforcing member for the machine wall.

ことで脱穀装置の機壁の強度を高められるに至った。As described above, therefore, it is possible to prevent the relatively large straw dust and the like from entering the suction air passage of the dust exhaust fan, so that the dust dust is caught on the rotating shaft of the dust exhaust fan. It also eliminates problems such as rotation drive being hindered by straw dust and the blades of the dust-exhaust fan being damaged by straw dust, and by installing a horizontal rod between machine walls, We were able to increase the strength of the machine wall.

A second Glen Pan 17 that receives the discharged processed material, a first Straw Rack 18 that is connected to the rear end of the second Glen Pan 17, and a second Straw Rack 19 that is positioned below the first Straw Rack 18. And a second chaff sheave 16 positioned below the second Straw rack 19 are arranged. And the first Glen Pan 14
Between the rear end portion and the first object collecting portion 8, the first chaff sheave 15 is pivotally attached to the left and right machine walls of the threshing case 11 so that the first chaff sheave 15 can swing about the horizontal axis at a position near the second chaff sheave 16. I am doing it. The first Glen pan 14 has a fixed front portion
In addition to being configured as A, the rear portion is configured as a movable Glen pan 14B that is movable back and forth so that the rear end position can be changed below the fixed Glen pan 14A. This movable gren pan 14B is linked to a manual lever provided in the control section through a release wire 20, and by appropriately swinging the manual lever, the movable glen pan 14B is arbitrarily moved to and from the fixed glen pan 14A. Can be made. Then, the movable chamfer pan 1 is linked with the manual lever by an interlocking mechanism (not shown) so that the first chaff sheave 15 swings in conjunction with the movable grain pan 14B.
A large gap is not formed between the rear end of 4B and the front end of the first chaff sheave 15. As a result, the installation inclination angle of the first chaff sheave 15 can be changed in association with the forward / backward movement of the movable Glen pan 14B, and the chaff plate in the forward inclined posture arranged side by side on the first chaff sheave 15 is provided. 15a ... is the first angle
Since it changes with the change of the inclination angle of the chaff sheave 15,
The distance between the adjacent chaff plates 15a in plan view can be changed according to the condition of the processed material, for example, the type of crop of rice and the dry and wet condition of the processed material.

A plurality of diffusing teeth 10a for loosening the lump-shaped processed material discharged from the dust delivery port 5 are provided in a juxtaposed manner along the left-right direction. Further, the dust exhaust fan 12 has a plurality of blades 12
A is configured as a cross-flow fan arranged in parallel along the rotation direction, and is also configured to be drivable via a belt transmission mechanism from a driving unit (not shown) as in the diffusion cylinder 10.
A horizontal rod 21 made of a square pipe is provided at an intermediate position between the diffusion cylinder 10 and the dust removal fan 12, and the left and right side walls 11 on which the diffusion cylinder 10 and the dust removal fan 12 of the threshing case 11 are installed.
It is fixed to A and 11B by being connected by bolts or welding while being installed. By thus constructing the horizontal rod 21, the threshing case 10 can be reinforced. Further, since the horizontal rod 21 is provided in a state in which it is interposed in the suction path of the dust and the like to the dust exhaust fan 12, small dust may ride on the suction wind of the dust exhaust fan 12 and bypass the horizontal rod 21. While passing through the upper and lower sides of the horizontal rod 21, the dust is sucked by the dust-exhaust fan 12 and discharged to the outside of the machine body.
Will not be able to bypass and will collide. Due to this collision
The dust and the like are not sucked by the dust-exhausting fan 12 and are dropped and supplied to the lower swing sorting device 6.
