Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a threshing processing device and can be used in combine harvesters, harvesters, and the like.

In the prior art, Japanese Unexamined Patent Publication No. 137271/1987, there is a structure in which a threshing chamber is installed at the axial rear of the threshing chamber in which the handling drum is mounted, and which is located opposite to the upward rotating part of the threshing chamber of the handling drum. The structure of a threshing processing device is described in which a processing cylinder for receiving and processing straw waste to be transferred is located, and a dust blower is located opposite to the downward rotating section, and is provided on the same axis. There is.

Problems to be Solved by the Invention Normally, threshed grains with grains that are threshed in a threshing room and contain a large amount of straw waste etc. are once supplied from the threshing room to a separate processing room for reprocessing. In such a configuration, if the threshing room and the processing chamber are directly connected and the straw waste etc. from the threshing room is directly supplied to the processing chamber, it is difficult to smoothly transfer the straw waste etc. between the two. Furthermore, straw waste and the like often contain a large amount of threshed grains, making single sorting inefficient.

Means for Solving the Problems This invention provides a threshing room (3) on which a handling cylinder (1) is mounted on a shaft (2).
At a position communicating with the suction sorting chamber (7) at the rear in the direction of the axis (2), there is a section opposite to the downward rotating (a) part of the threshing chamber (3) of the handling cylinder (1). This threshing room (3)
The oscillating sorting shelf (8) of the suction sorting chamber (7)
Process of receiving and processing straw waste transferred above 1ii1
The threshing processing apparatus is configured such that (4) is provided on the same shaft (6) with cross-flow fans (5) located opposite to the upward rotation (b) side.

Functions and Effects of the Invention The husk that is transferred through the threshing chamber (3) from the front side to the rear side along the direction of the axis (2) is threshed by the rotation of the drum (1) and handles the tip of the husk. In the threshing room (3), a large amount of straw waste tends to accumulate near the downward rotation (a) of the handle P (1), but in the rear end of the threshing room (3), this This threshed grain containing a large amount of straw waste is discharged to the suction sorting chamber (7) located near the downward rotating part (A) of the barrel (1).
The swinging sorting shelf (8) is oscillated and the processing cylinder on the rear side (
4), and is suctioned and discharged by the rotational suction of the cross-flow fan (5), subjected to a sorting action, and processed into the processing cylinder (
In section 4), this swing sorting shelf (8) faces the part where a large amount of straw waste is transferred, so it is easy to scrape in the straw waste, and the cross-flow fan (5) )
On the side, the suction of straw waste is reduced to improve the dust removal effect,
It is possible to reduce the scattering of grains outside the machine.

Embodiment In the illustrated example, the threshing room (3) is equipped with a threshing net on the lower side, and is connected from the culm supply port (9) on the front side to the discharge port (lO) on the rear side.
A culm transfer device (11) is provided along the negative side toward the threshing chamber (3), and a processing cylinder (4) and a cross-flow fan (5) are mounted on the shaft (6) at the rear of the threshing room (3). A sorting room (7) is provided between the threshing room (3) on the front side and the processing room (12) and dust removal room (13) on the rear side.
A swing sorting shelf (8) is installed on the lower side, and a culm chamber (1) is installed on the upper side.
4). The swinging sorting shelf (8) extends from the bottom of the threshing net to the outlet (10) and the lower diameter of the sorting chamber (7) to the entrance of the processing chamber (12) and dust removal chamber (13). The upper surface forms a rack-like uneven surface,
It is equipped with a grain leakage hole, and it swings back and forth to transfer the threshed grains and to sort the grains through leakage. Processing room (1
2) may be configured such that a processing plate (15) is provided on the lower surface to cause the processed grains to leak out, and a portion of the processing residue is sucked into the axially adjacent cross-flow fan (5). (1B) is the dust exhaust port of the dust exhaust chamber (13).

(17) is a straw rack installed at the bottom of the rear end of the swinging sorting shelf (8), which receives grains, straw waste, etc. leaking from the processing chamber (13) and sorts them by swinging. The rear end looks into the straw waste outlet (18), and (18) is a sorting air passage below the swinging sorting shelf, and is configured so that air can be blown from the air-pressure winch. A second gutter (20) etc. are installed.

(21) is a second husk machine, which is provided to supply the second product from the second receiving trough (20) to the threshing room (3). (22) is a culm transfer device.

The threshing room (
3) The tips of the ears fed inside are threshed.

Threshed grain leaks from the threshing net, is received on the swinging sorting shelf (8), and is sorted while being transported backwards by swinging, and from the discharge port (10), Rotation (a)
On the closer side, straw waste with relatively heavy grains is concentrated and falls onto the swinging sorting shelf (8) of the sorting room (7), and on the upward rotating (b) side, relatively Light straw waste, dust, etc. are discharged and sorted while being transferred on the swinging sorting shelf (8), and grains, etc. are allowed to leak out, but the straw waste remaining on the upper surface is mainly stored in the processing chamber (12). ) and is reprocessed by the rotation of the processing cylinder (4), but this sorting chamber (7)
The dust inside is sucked by the rotation of the cross-flow fan (5) and discharged to the outside of the machine from the dust exhaust port (1B).
The straw waste air-selected in step 8) and the straw waste leaking from the processing chamber (12) etc. are discharged from the discharge port on the straw rack (17).
