Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a swing sorting device for a threshing machine, and can be used for a combine harvester.

Conventional technology The threshed grains leaking from the threshing net and the second grains returned from the second grain lifting machine are received on the top surface of the swinging sorting rack, and the grains are leaked from the sorting rack plate while being shaken and transferred. Let it go down.

Problems to be Solved by the Invention In the sorting action on the swinging sorting shelf below the threshing net, the threshed grains leaking from the threshing net contain a large amount of grains and a small amount of straw waste, but the second The second product that is fried and returned from the grain machine contains a large amount of straw waste. For this reason, when these threshing and second grains are not transferred on the same oscillating sorting rack board and are sorted by leakage, the grains are oscillated and transferred with a bowl containing grains in the second grain, which has a lot of straw waste. This reduces the grain sorting efficiency.

Means for Solving the Problems This invention provides a method for preventing leakage from the threshing net (3) of the threshing chamber (2) at the lower end of the threshing net (3) of the threshing chamber (2) in which the handling drum (1) is housed. The threshing room (5) where the grain is being returned from the second hoisting machine (4) to the threshing room (2)
The oscillating sorting shelf (6) receives second grains falling from the threshing net (3) and sorts the grains while oscillatingly transporting them. Rack board (
The vertical width of 7) is a sorting rack plate (8) that sorts the grains while transporting the second product falling from the second reduction chamber (5).
The swing sorting device of the threshing machine is configured to be narrower than the vertical width of the threshing machine.

Effect of the Invention When the threshed grain is threshed in the rotating threshing chamber (2) of the handling cylinder (11) and leaks from the threshing net (3), it passes through the swinging sorting rack (6).
) while being oscillated and transported on the threshing net (3).
) The grains leak out while being transferred over the sorting rack plates +71 to +81 corresponding to the terminal ends of the sorting rack plates (7) (81), and the straw waste is further transferred forward on these sorting rack plates (7) (81) to be sorted.

The second grains sorted on this swinging sorting rack (6), sorting air passage, etc. are transferred to the second grain lifting machine (4) and returned to the threshing room (2) for re-threshing. The second product, which falls directly from the second reduction chamber (5) during the transfer of the second product, is received by the sorting rack plate (8) of the lower swinging sorting shelf (6) and shaken. be selected.

Threshing grains that are transferred and sorted on the sorting rack plate (7) have little stagnation of straw waste on the upper surface of the sorting rack plate (7) because almost no second material is dropped onto this upper surface, and the first sorting rack plate (
7) The vertical width is narrow so that grains can be sorted quickly. In addition, since the vertical width of the sorting rack plate (8) is wide, the second item falling onto the sorting rack plate (8) also leaks straw waste, and the straw waste is transferred. The processing can be carried out quickly and the threshing and sorting processing can be improved.

Effects of the Invention In this way, the sorting rack plate (7) of the swinging sorting shelf (6) below the threshing net (3) is arranged so that the sorting rack plate (8) receives the second product falling from the second reduction chamber (5). ) is narrower than the vertical width of the grain, so that the leakage sorting of the threshed grain containing a large amount of grain can be carried out quickly, and the straw waste can be quickly fed during the second sorting, making the first sorting better. can be maintained.

Embodiment In the illustrated example, the threshing room (2) rotates and transmits the handling cylinder (1) through the handling cylinder shaft (9), and a threshing net (3) is provided on the lower side.
A threshing cover (II) that can be opened and closed is provided on the upper side, and a husk culm that clamps and transfers the stock part of the husk from the front culm supply port (1υ) to the rear culm discharge port (121) is provided on the upper side. Transfer device (13
has been established. Below this threshing room (2), there is a swinging sorting shelf (6) for shaking and sorting in case of leakage of threshed grains.
It is located within 4. At the bottom of this sorting room 04, there is a sorting air passage that passes the sorting air from the front pressurized winch (Is) to the suction dust extractor +l1il at the rear upper part, and there is a first transfer gutter at the bottom that receives the grains. (+71) and a second transfer gutter (18) containing unthreshed grain, etc.

On the head side opposite to the husk transfer device (13) of the threshing room (2), there is a drop chamber 12G between the threshing net (3) and the side wall (19).
The upper end communicates with the threshing room (2), and the lower end looks over the swinging sorting shelf (6). The upper end of this falling chamber (end) is provided with a guide plate (211) at the front and rear intermediate parts, and a part of the second fried grain of the second grain barrel Qδ that communicates with the rear end is connected to this guide plate +
211 to guide the grain and return it to the threshing room (2) side. The second grain lifting machine (4) is installed at the end of the second transfer trough +In, has a jump wheel, and communicates with the upper grain lifting cylinder (2δ).

The swinging sorting shelf (6) has a frame that can be swung back and forth by a crankshaft, and has a suction dust extractor + 16 from the lower part of the culm supply port + 10 on the front and back through the lower part of the exhaust culm port 021. ) A transfer plate 24 with a corrugated upper surface is provided on the front side of the lower part of the threshing net (A), and is moved by swinging to receive the threshed grains leaking from the threshing net (3). Move it towards the rear. On the rear side of the lower part of this threshing net (3), sorting rack plates (7) which are inclined with the upper edge at the rear and the lower edge at the front are arranged at appropriate intervals one front and back. The grains are allowed to leak from the spacer of the sorting rack plate (7), and the straw waste is received at the upper edge and transferred to the rear, which is connected to the rear end of the transfer plate.

This sorting rack plate (7) is provided so that its vertical width becomes larger on the falling chamber 21 side, and its upper edge is formed higher than the upper edge of the other portion facing the stock head side.

The problem is the guide plate installed on the transfer plate I24, and the falling chamber +2 [
) is provided so as to separate the second threshing net (3) from the threshing net (3) that is leaking out and guide the transfer.

(5) is a straw rack, which is provided opposite to the lower part of the discharge culm (121), and collects not only the straw that falls from this discharge culm (02+) but also the straw that is sent out from the first sorting rack plate (7). 12G is a sorting rack plate, which has the same structure as the above-mentioned sorting rack plate (7), and allows grains to leak out from the straw waste during oscillating transfer.

G! 91 is a stroke rack at the rear end. C[Il is a sorting net, which is provided along the lower side of the sorting rack plate 12, to further sort out the threshed grains leaking from this sorting rack plate 112I.

The second transfer gutter +11 is provided at the lower part of the straw rack (291) and contains straw waste that has been wind-separated from the first straw that has been sorted under the first sorting net OL, and contains unthreshed grains. etc. can be transferred and returned to the second reduction room (5) using the second grain lifting machine (4).

Most of the grains threshed in the threshing room (2) leak through the threshing net (3) at the front side, so the threshing is carried out from the transfer plate Q41 onto the sorting rack plate (7) with a narrow vertical width. Most of the grains are grains, and since the vertical width of the sorting rack plate (7) is narrow, leakage is likely to occur, and grain leakage is quickly sorted.

In addition, the second grain hoisted into the second return chamber (5) by the second hoisting machine (4) is guided into the threshing chamber (2) while being guided by a guide plate I21), where it is re-threshed. However, relatively heavy items such as grains are stored in this second reduction chamber (5).
the lower transfer plate 124], or the sorting rack plate (
8) Can be received above. These second items contain a large amount of straw waste, and are transported along with a portion of the threshed grains leaking from the threshing net (3) to the sorting rack plate (8) while being guided by the partition plate 12i19 between the transfer plate and the upper part. are selected above. During sorting on this sorting rack plate (8), since the vertical width of the sorting rack plate (8) is wider than other parts, it is easy to receive 1 sorting resistance, and leakage of straw waste etc. is difficult and the straw - The grains can be quickly transferred to the rack (5) side and the grains can be sorted out from the gap 4 to improve accuracy.
