Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a threshing section that performs a threshing action while handling and transferring the shell culm to be threshed in the direction of the axis of the barrel, and a threshing section that is located at the lower part of the threshing section and swings the threshed grain. The purpose of the threshing sorting device is to have a sorting section that performs a wind sorting action while transferring the grain, and a fourth grain collecting section is formed at the end of the transfer of the threshing section. Although it is compact and easy to configure, it makes effective use of the sorting section,
The purpose of this invention is to make it possible to separate and collect No. 4 grains into No. 1 and No. 2 grains, and to effectively and appropriately dispose of waste materials.

That is, in the conventional threshing and sorting device, the threshed grains are transferred and sorted in the same direction as the clamping and transferring direction of the threshing section. In order to ensure a sufficiently long sorting distance when sorting grains and disposing of waste mixed in the grain, the sorting section is designed so that its transfer end protrudes longer than the transfer end of the threshing section. This has the disadvantage that the entire device becomes larger and more complicated.Especially when it is mounted on a combine harvester, it protrudes in an overhang shape at the rear of the machine, causing damage to the machine at the edge of the ridge. It had a very disadvantageous configuration, with its protruding parts colliding with the ridges when traveling.

The present invention has been developed in consideration of these points, and it is possible to make the entire device more compact without deteriorating the sorting performance, and moreover, it is possible to effectively sort the fourth grain and to treat waste from the entire device. The aim is to

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

In addition to mounting a processing device so that it can be raised and lowered, a threshing and sorting device C is mounted on the machine body a, and a conveying device d is provided for conveying and supplying the harvested husk to the threshing and sorting device C.

As shown in FIGS. 2 and 3, the threshing and sorting device C uses a clamping and transferring device 2 located along the traveling direction of the machine body a to sort the threshed grains (that is, the grains supplied from the conveying device d). A threshing section A performs a threshing action while holding and transferring the harvested husk culm 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 threshed 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 dust sorting 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 holding 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 placed on 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 portions 16 and 17 are provided to separate and collect the sorted first grain and second grain and transfer them to the other side wall portion 8 through 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 transfer portion formed as a feed plate portion 9a for specific gravity sorting, and a second half of the transfer portion formed as a rope portion 9b for sorting and dropping. The swing sorting plate 10 on the side of section C transfers its first half to the feeding plate section 10a for specific gravity sorting, and transfers the middle section to the rope section 1 for dropping sorted items.
0b, the latter half of the transfer is formed into a rack part 10c for dropping dust.

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 in a state that does not protrude laterally outward.

The dust cutter 4 uses the space 18 as an installation space, and also uses the clamping and transferring device 2 as a dust supply device, and
It is internally installed in such a way that it does not protrude laterally outwardly than the gripping and transferring device 2, and also includes a group of rolls 4a and a rotary blade 4b that scrape the dust by folding it into two at the center in the longitudinal direction. It is configured to shred the dust from the fixed blade 4c.

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. A lifting rotating body 5a for transporting grains is directly connected to the screw 15, and a lifting guide cylinder 5b for guiding the lifted grains to the threshing section A is arranged so that the space formed in the upper part of the dust sorting section C is vertically inclined. It is configured so that it is placed in a horizontal position.

An inclined guide plate 19 is connected to the end point in the transfer direction of the threshing section A for guiding the grains downward from the transfer start end of the oscillating sorter 9 in the sorting section B to the side of the oscillating sorting plate 9. Set up
A No. 4 grain collecting section is formed to collect No. 4 grains to the sorting section B.

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 waste straw discharge port for discharging shredded waste straw to the outside.

In summary, in the threshing sorting device according to the present invention, the transferring direction of the sorting section is configured to be opposite to the clamping transfer direction of the threshing section, and the threshing section The present invention is characterized in that an inclined guide plate for guiding the No. 4 grains from the grains downward toward the oscillating sorting plate is provided in series, and therefore, it has the following advantages.

That is, since the threshing part is transferred and sorted in the direction opposite to the direction of movement of the threshing part, the sorting part can be housed in the middle of the threshing part in the direction of movement, making it easy to make the whole structure small and compact. However, by providing a sufficiently long sorting distance for threshing with a low grain occupancy rate that occurs on the straw outlet side of the threshing section, and by applying a powerful selection function 9, very good selection performance is achieved. can.

Furthermore, the No. 4 grains collected at the beginning of the transfer of the N13 section can be air-sorted using a sufficiently long sorting section.
In addition to improving the performance by separating and recovering the first and second grains mixed in the fourth grain, the sorting section B also handles the fourth grain waste.
Since the dust removal process can be carried out both at the beginning and at the beginning, it has also been possible to simultaneously achieve the effect of intensively processing the dust particles from the entire device.
