Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a threshing section that carries out a threshing action while pinching and transferring the threshed culm in the axial direction of a handling cylinder using a clamping and transferring device, and a threshing section that performs a threshing action while clamping and transferring the culm to be threshed in the axial direction of a handling cylinder, and a main sorting section that performs a wind sorting action while being oscillated and transferred, and a waste sorting section that sorts and processes the waste sent out from the threshing section while being transferred;
A dust blower for forcibly exhausts the dust in the dust sorting section to the outside, a straw cutter for shredding the threshed husks sent out from the threshing section, and a straw cutter for shredding the threshed husks sent out from the threshing section, and Regarding the threshing equipment equipped with a thrower that returns the grain to the threshing section, the purpose is to arrange the various parts of the equipment in a rational manner so as to be particularly effective when equipped with a combine harvester. The aim is to have a well-organized and compact structure.

In other words, when the combine harvester is installed, if the threshing device protrudes for a long time in an overhanging state at the rear of the machine, or if the straw cutter or dust blower protrudes locally, it may cause problems, especially when the machine turns at the edge of a ridge. Safety problems may arise, such as the rearwardly protruding device portion colliding with the ridge, or the worker coming into contact with local protruding device portions.

Therefore, it is desired that the threshing device be configured to be well-organized, small and compact, but simply reducing the size and compactness of the device is likely to result in a decrease in the sorting performance of the threshing and sorting device.

In view of these points, the present invention aims to achieve miniaturization and compactness by improving the arrangement of the device without degrading the threshing and sorting performance.

Embodiments of the present invention will be described below based on the drawings.

In addition to mounting the processing device so that it can be raised and lowered, a threshing device C is also installed on the machine body a, and the harvested husk is transferred to the threshing device C.
The configuration includes a conveying device d for conveying and supplying.

As shown in FIGS. 2 and 3, the threshing device C collects grains to be threshed (that is, the harvested grains supplied from the conveying device d) by a clamping transfer device 2 located along the traveling direction of the machine body a. A threshing section A performs a threshing action while pinching and transferring the husks) in the axial direction of the handling cylinder 1, and a main sorting section B performs wind sorting while swinging and transferring the threshed grains in the threshing section A. , a dust sorting section C that sorts the waste sent out from the threshing section A while swinging and transferring it, a dust blower 3 that forcibly removes dust from inside the straw sorting section C to the outside, and the threshing section A cylindrical straw cutter 4 that folds the threshed husk (waste straw) sent from A into two at its longitudinal center position and shreds it, and returns the main sorted second grain to the threshing section A. It has a thrower 5.

A receiving net 6 is installed below the handling barrel 1 of the threshing section A to allow the grains being threshed to flow down, and the clamping and transferring device 2 is connected to a feed chain 2A that is vertically opposed to each other.
It is composed of a clamping rail 2B and a clamping rail 2B.

The main sorting section B and the waste sorting section C are located below the handling drum 1 and between the side wall section 7 at the bottom of the clamping and transferring device 2 and the other side wall section 8 opposite thereto. B is located on the side of the clamping and transferring device 2, and the side wall portion 7 is approximately aligned with the handling cylinder 1. They are arranged in parallel in the lateral direction so as to be positioned directly below the axis of the two, and the transfer direction thereof is opposite to the direction of transfer by the clamp transfer device 2.

In addition, the main sorting section B and the waste sorting section C are composed of a swinging sorting plate 9 that swings and sorts the threshed grains flowing down from the receiving net 6, and a threshing section A.
The oscillating sorting plate 10 that oscillates and sorts out the dust discharged from the oscillating sorting plate 10 is integrally oscillated to a position below the receiving net 6 via the eccentric rotation pivot support 11 and the oscillating link 12. A common wind selection path 13 is provided below both swinging sorting plates 9 and 10 for wind sorting the swinging sorted material into first grain, second grain, and waste dust. Common collecting sections 16 and 17 are provided to separate and collect the selected first grain and second grain and transfer them to the other side wall portion 8 via screws 14 and 15, respectively.

The oscillating sorting plate 9 on the side of the main sorting section B has a first half of the transport portion formed as a feed plate portion 9a for specific gravity sorting, and a second half of the transport portion formed as a rope portion 9b for dropping the sorted items, and the dust removal Sorting section C

They are formed respectively in c.

A winnower 13A that generates a sorting wind in the wind selection path 13 is arranged at a transfer start position below the swinging sorting plates 9 and 10.

The dust blower 3 has a space 18 formed outside the side wall portion 7 on the lower side of the clamping and transferring device 2 as an installation space, and corresponds to the transfer end portion of the sorting section B.
It is attached to the side wall portion 7 without protruding laterally outward.

The straw removal cutter 4 uses the space 18 as an installation space, and the clamping and transferring device 2 also serves as a removal straw supply device, and
It is internally installed in such a way that it does not protrude laterally outwardly than the clamping and transferring device 2, and this also includes a group of rolls 4a that fold the waste straw in two at the center in the longitudinal direction. The rotary blade 4b and the fixed blade 4c are configured to shred the waste straw.

The thrower 5 is installed in such a manner that it communicates with the second grain outlet 17a from the second grain collecting section 17 formed in the other side wall portion 8, and also lifts the second grain by rotational action. The lifting rotating body 5a for feeding is provided directly connected to the screw 15, and the upper part of the lifting guide cylinder 5b for guiding the lifted grains to the threshing section A is connected to the space formed in the upper part C of the dust sorting section C. It is constructed by providing the cross section in an upward and downward tilted position.

Furthermore, at the end of the threshing section A in the transfer direction, a sorting section B is provided.
No. 4 grain collecting section which collects No. 4 grains into sorting section B by continuously installing an inclined guide plate 19 that guides the grains downward in the transport direction of the oscillating sorting plate 9 to the side of the oscillating sorting plate 9. This is the formation of the ridge.

In addition, in the figure, 20 is a partition plate installed vertically to partition the threshing part A and the upper space of the waste sorting part C, and 21 is the terminal part of the partition plate 20 in the transport direction of the threshing part A, and A dust outlet is formed in the upper part to send the waste from the threshing section A to the dust sorting section C, and 22 is a port for guiding the grains that have fallen before being transferred into the threshing section A to the main sorting section B. To do so, receiving net 6
23 is a shredded waste straw discharge port for discharging the shredded waste straw to the outside.

In summary, the threshing device according to the present invention has the thrower 5 sandwiching the handling drum 1 and positioned on the opposite side from the holding and transferring device 2, and the upper part of the thrower 5 being bent toward the upper part of the handling drum 1, The main sorting section B and the waste sorting section C are connected to the threshing section A.
The main sorting section B and the dust sorting section C are arranged in parallel in the horizontal direction on the lower side, and the main sorting section B and the dust sorting section C are inserted into a space formed on the lower side of the upper part of the thrower 5. The sorting section C is arranged to be offset from the threshing section A, and the transfer direction of the main sorting section B and the waste sorting section C is set such that:
configured to be opposite to the clamping and transferring direction of the threshing section A;
It is characterized in that the dust blower 3 and the straw removal cutter 4 are disposed on the side wall side of the lower part of the threshing culm holding and transferring device 2 in the threshing section A. As a result, we were able to achieve significant effects.

That is, focusing on the fact that the threshed grains and waste at the starting end in the transfer direction of the threshing section A have a high grain content and can be sufficiently sorted even if the sorting distance is short, each Since the transfer direction in the sorting sections B and C is configured to be opposite to the transfer direction in the threshing section A, the sorting section and the waste sorting section corresponding to the starting end in the transfer direction of the threshing section A,
Since it can be effectively used as a sorting action path for threshing and waste materials that are generated at the end of the threshing section A in the transfer direction due to their low grain content and lack of sorting performance, Although the arrangement is compact enough to accommodate the sorting section B and the dust sorting section C, a sufficiently long distance can be ensured to ensure reliable and good sorting performance.

Moreover, the space below the space in the width direction of the device, which is required for the return of the second grain to the threshing section A by the thrower 5 and is occupied by the curved part of the throat tube section, can be used as the installation space for the waste sorting section C. By using this, the sorting section B and the waste sorting section C, which are parallel to each other in the horizontal direction, can be entirely displaced toward the thrower 5 side, so that a space is formed below the holding and transferring device 2 that enters the device side. can do.

Therefore, this space can be used as an installation space for the dust blower 3 and the straw cutter 4, so that the dust blower 3 and the straw cutter 4 can be arranged without protruding locally.

As described above, the present invention can be configured into a compact and well-organized product by improving the layout and configuration without degrading threshing and sorting performance, and is particularly useful for threshing that is mounted on a combine harvester. We have now been able to provide the device.
