Description

[Detailed description of the invention] [Industrial application field] This article relates to the Kihatsu Fi4Fi threshing sorting device.

[Conventional technology]

Conventionally, in threshing sorting equipment, the receiving net is fixed;
This may lead to the following inconveniences.

[Problem that the invention seeks to solve]

That is, in the case of threshing of shell culms with a high humidity of 9 degrees, or wet threshing, the receiving nets tend to become clogged early because the threshed products tend to adhere to the grains due to moisture.

It is an object of the present invention to prevent clogging of the receiving net, and more specifically, to make it possible to uniformly supply the membrane-removed material to the sorting section by using the configuration for this purpose. be.

The threshing sorting device according to the present invention is characterized in that a large number of receiving net forming units are movable as one unit, and
The first mounting position forms a threshing material dropping passage with a small cross-sectional area, and the second mounting position forms a threshing material dropping passage with a large cross-sectional area. The handling action path and the return path are attached to the rope-like body and have a handling action path along the threshing rotary body and a return path located below the handling action path. Further, the loop path W! is moved from the tip side to the stock base side on the return path portion. !
! The operation and effects are as follows.

[For production]

The portion of the handling barrel or the like that was in the handling action path facing the threshing rotating body is moved to the return path located on the opposite side of the threshing rotating body with respect to the handling action path. ,
In addition, by rotating the catch net so that the part that was in the return path moves to the handling action path, the part of the catch net that was in the handling action path and on which the material to be treated is attached is moved to the return path. As it moves to the route, it bends along the receiving net winding member and is reversed from the upward direction toward the threshing rotating body to the downward direction, so that the attached processed material is The part of the receiving net that is in the return path and has no processed material attached thereto replaces the part of the receiving net that was facing the threshing rotating body and faces the threshing rotating body. . That is, the adhering processed material is removed, and the receiving net portion to which no processed material is attached is replaced so as to face the threshing rotary body.

The threshed material is handled with a large amount on the ear tip side and falls from the receiving net in the action path, but the receiving net reduces the cross-sectional area of the processed material falling path on the ear tip side, and on the stock head side. While increasing the cross-sectional area of the processed material falling passage, the return path section is moved from the ear side to the stock head side, and a part of the threshed material that falls from the ear side of the handling action path section is extracted on the ear tip side of the return path section. While dropping the net, the rest is placed on the inner surface of the receiving net loop and transferred to the stock side, and the nuki is allowed to fall.

〔Effect of the invention〕

By removing the adhering material and replacing the receiving net portion so that the processed material does not remain attached to the receiving net portion facing the threshing rotating body, clogging of the receiving net can be effectively prevented and wet Threshing can now be done more efficiently. In addition, clogging can be prevented by reducing noise and the occurrence of aircraft filming due to the rotation of the receiving net rather than applying vibrations to the receiving net, making work more comfortable.
became.

By transferring a part of the treated material that falls from the tip side of the handling action path to the tip side, the falling supply for sorting the treated material is distributed in the direction of the culm so that it is not biased toward the tip side. This made it possible to efficiently sort the grain after threshing. Moreover, since the receiving net can be used for dispersing the processed material, it is only necessary to configure the receiving net so that the cross-sectional area of the processing material falling passage can be changed, which is advantageous from a structural and economic point of view.

〔Example〕

As shown in Fig. 2, the threshing feed chain fl K threshes the harvested grain culm supplied to the handling chamber (2) K with one rotating handling cylinder (3), and the threshing straw is transferred to the threshing feed chain fl K. [From 11K, the threshing section is configured so as to be transported from the handling room fi+, and includes a drivable swinging sorting device (6) and a handling cylinder for the threshed material that is dropped and supplied from the receiving net and dust exhaust port (6). (3) A sorting section that has a winnowing machine (7) that supplies sorting air in the axial direction and a rotating fan (8) that sucks and sorts out dust and discharges it to the outside of the machine is installed below the threshing section. In addition, a screw conveyor (9) for transporting the No. 1 processed material from the sorting section to the outside of the machine, and a screw conveyor (10) for returning the No. 2 processed material from the sorting section to the handling room (2) are installed in the sorting section. It is installed at the bottom of the machine to form a threshing and sorting device for a combine harvester.

The threshing section is structured as follows in detail.

That is, as shown in Figs. 3 to 5, a large number of plate-like receiving net construction units (11) are housed in a pair of endless chains +12), Q2) arranged in the longitudinal direction. By attaching the receiving net (4), the receiving net (4) is configured in an endless band shape. As shown in FIGS. 1 and 4, this receiving net (4) winds each of the pair of chains θ and α around the drive chain chain α and the idle chain chain 041. By rotating and slidably attaching multiple chain guide rails (I5) and (llf)K, the handling action path section (6
), a first return path section (7) in the vertical direction of the aircraft, and a second path section Q81 located below the end portion of the handling action path section, and 2. The KIX is attached so that the end of the return path is driven to rotate in the direction of moving from the tip side to the stock base side (in the direction of the arrow). Each of the receiving net structure units (11) is pivotally connected to the endless chain α through the mounting portion (lla) so as to swing around the axis (P), and the first As shown in the figure, in the handling action path section 04, the steel is moved forward and backward in the moving direction so as to form a path α through which the threshed material falls through the through holes of the receiving net structure unit (11). The first attachment where the end of the is almost in contact with the adjacent receiving net forming unit (11) is configured so that the posture is based on its own weight and the receiving by the endless chain θ2)K, and the second return path section - In the tip side portion, the first attachment is configured to be operated by the closing action of the operating member in the posture, and the second return path portion (in the stock side portion of 181, the first attachment unit body (11

In short, the grain culms are inserted between the handling barrel (3) and the receiving net portion at the end of the handling action path, and the threshed material is passed through the receiving net (4) and the dust outlet (5). It is designed to fall and supply to the sorting section. Even if the threshed material adheres to the handling action path section 0, the first and second return path sections α
The receiving net (4) is rotated so that the portion of the receiving net that falls at the force of 081 and has no deposits is replaced with the end of the handling action path, thereby preventing clogging of the receiving net (4). There is. Further K transfers a part of the threshed material falling from the tip side of the handling action path section O to the second return path section (18
), the first attachment is from the through-hole passageway (I@) of the receiving net structure unit (11) in the position
