BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing / sorting device for combine harvesters, etc., and more particularly to a threshing / sorting device for combine harvesters, etc. It can be used for etc.

[0002]

2. Description of the Related Art Originally, there are two types of combine harvesters, that is, a type in which all culms are put in and a type in which they are self-removed. An effective selection was made by using the main sardines installed on the upper side of the equipment to improve threshing accuracy and efficiency. However, in recent years, with the rapid sophistication of combine harvesters, the amount of threshing treatment has increased, and the work called threshing of high-moisture culms, so-called leak handling, has been increasing more and more. For this reason, the first sorting part and the second sorting part in the sorting part are made to swing so as to prevent a decrease in the sorting performance of the grain that has leaked from the handling chamber, but straw waste rather than grain. In the No. 2 sorting section, where the wind from the main Karasu is weak and the direction of the wind changes due to the swinging action of the sorting section, the sorting performance deteriorates and the grain due to poor sorting of the No. 2 grain is reduced. And the second product is stagnated or clogged in the second selection part, and the threshing work is hindered. For this reason, an auxiliary Kara is provided between the No. 1 and No. 2 gutters to assist in the selection of the main Kara so as to improve the sorting performance of the second Kara. There is a problem in that it is difficult to pull out the swing sorting device because it becomes an obstacle when the swing sorting device is detached during maintenance of the threshing sorting device.

The present invention provides an auxiliary Karako, which assists the selection of the second product in the second selection section of such a threshing selection device,
The swing sorting device is intended to be removable so as not to get in the way when it is attached and detached.

[0004]

According to the present invention, below the handling chamber 2 in which the handling barrel 1 is mounted, the first sorting unit 3 and the sorting unit 3 are arranged in the axial direction of the handling barrel 1 from the inlet side to the outlet side. A swing sorting device 5 connected to the number sorting unit 4 is installed, and a main sardine 7 that blows air to a sorting air passage 6 of the swing sorting device 5 is arranged below the upper side of the swing sorting device 5. At the same time, in the threshing sorting device in which the first gutter 8 and the second gutter 9 are provided below the first sorting part 3 and the second sorting part 4, respectively, below the swing sorting device 5, A threshing / sorting device for combine harvesters or the like is characterized in that an auxiliary Karahi 10 for assisting the sorting wind of the main Kara Noh 7 is detachably provided between the gutter 8 and the No. 2 gutter 9.

[0005]

[Advantageous Effects of the Invention] With the above configuration, in the sorting section, the threshing that has been threshed in the handling room and leaked is performed by the swinging action of the swing sorting device and the blowing of air into the sorting air duct by the main and auxiliary Karasu The first item and the second item are selected according to the action, and especially the second item's selection performance is improved by the auxiliary Kara that is detachably installed between the first and second gutters. The collected first and second products are respectively collected in the first and second product collecting units, and the first product is transferred to the grain storage unit through the transfer device, and the second product is transferred through the transfer device. It returns to the handling room through.

When it is necessary to detach the rocking sorting device in the threshing sorting device when performing maintenance or the like in such a threshing sorting device for combine harvesters, the swing sorting device is moved to the rear side of the threshing sorting device. When pulling out, it is difficult to take out because the auxiliary Kara is an obstacle, but at this time, for example, the cassette-shaped auxiliary Kara can be easily taken out of the threshing sorting apparatus together with its casing. Can be easily removed from the threshing selection device.

Further, between the second gutter 9 and the first gutter 8 is adjacent to the lower side of the first fixed selection shelf 37, and four blades 41 combined in a cross shape are configured in a double row. A cassette-shaped auxiliary Kara 10 arranged inside the casing 42 is arranged.
Is provided so as to blow air toward the upper surface of the second swing selection shelf 35. In addition, an insertion / removal hole 44 for allowing the auxiliary Karako 10 to be inserted / removed in / from the left side plate 43 of the sorting section 25.
The right side plate 45 is fixedly provided with a support guide 46 for supporting the right end portion of the casing 42 of the auxiliary Kara that has been inserted into and removed from the sorting unit 25, and the left end of the casing 42 of the auxiliary Kara that is 10 is provided. A fastening arm 47 fixed to the left side plate 43 is provided in a cross shape, and the fastening arm 47 and the left side plate 43 are screwed with a bolt or the like so that the auxiliary Karako 10 can be attached to and detached from the sorting section 25. To do.

Also, in order to discharge the grain-removed straw waste and dust, which have been sorted by the sorting section 25, to the outside of the machine, the all-cullet-injection-type combine has an open dust-exhaust port 48 and a self-extracting-type combine. Then, a dust exhaust fan 49 is provided and configured. Further, as shown in FIG. 6, a sorting unit input pulley 50 for inputting power for driving the sorting unit 25 is provided on the rear side of the left side plate 43 of the sorting unit 25, and from this sorting unit input pulley 50,
The first drive pulley 51 of the first screw conveyor 36 of the first gutter 8 and the second drive pulley 52 of the second screw conveyor 39 of the second gutter 9 and the belt rear surface provided in the vicinity of the auxiliary Kara 10 Loose pulley 5 driven by
3, a sorting unit drive belt 54 is stretched, and an auxiliary Karako drive belt 56 is stretched between the loose pulley 53 and the drive pulley 55 of the auxiliary Karoh 10.

Next, the operation of the above configuration will be described. The grain culms harvested by the harvesting device 12 are the threshing sorting device 17
The threshing grains that have been conveyed to the threshing sorting device 17 and have leaked the threshing net 26 that has been threshed in the handling chamber 2 fall onto the swing sorting device 5 of the sorting unit 25, and the swing sorting device 5 By virtue of the swinging action, first, the first chaff sheave 29 of the first sorting section 3 to the second chaff sheave 30 of the second sorting section 4 through the sieve line 31.
And is coarsely sorted by the gap between the blades 29a and 30a and the sieve line 31 during this period, and the grain loss leaks. It should be noted that the relatively large straw waste that has passed over the second chaff sheave 30 as it is is discharged to the outside of the machine from the open dust outlet 48 in the all cullet type combine harvester, and is discharged from the machine by the dust removal fan 49 in the self-removing combine harvester. Is discharged to.

Further, the grain loss that has leaked through the first chaff sheave 29 is sent from the Glen pan 32 to the Glen sieve 33, and the grain loss that has been intermediately selected by the Glen sieve 33 and leaked out becomes grains and fine straw waste. It falls on the No. swing selection shelf 3. During this fall, the sorting wind blasted by the main sardines 7 is blown to the sorting air passage 6, and the finishing of the most grain is performed by the wind sorting by this blowing and the specific gravity sorting by the swinging action of the swing sorting device 5. Sorting is performed, and while the first grain is accommodated in the first gutter 8 from the first swinging sorting rack 34, the sorting wind divided by the air flow adjusting plate 38 is fed to the first swinging sorting rack 34.
By blowing air between the first fixed sorting shelf 37 and the first fixed sorting shelf 37, finer straw debris is removed and stored in the first trough 8.
Grain tank 1 by the first screw conveyor 36
8 is transported.

The grain that has leaked through the No. 2 chaff sheave 30 is a No. 2 grain having a higher ratio of straw waste than the grain while being sent from the No. 1 chaff sieve 29 to the No. 2 chaff sheave 30. , The second object and the grains and fine straw debris that fly from the first selecting section 3 to the second selecting section 4 on the selecting wind merge and drop on the second swing selecting shelf 35. .. In addition, by the sorting air blown from the main Karino 7 by the sorting air passage 6 during the fall and the specific gravity sorting by the swinging action of the swing sorting device 5, the grain with branch shoots in the straw waste. A second product with a mixture of (commonly known as Kaginu) is selected, and the straw debris and dust separated by this selection are discharged to the outside of the machine from the dust outlet 48 that is open in the all-cullet-type combine harvester, and the self-removing type In the combine, it is discharged outside the machine by the dust exhaust fan 49.

Further, at the time of the sorting in the second sorting section 4, the sorting wind from the main Kara-no-Miru 7 is weakened, and moreover, the swinging action of the swing sorting device 5 causes the direction of the sorting wind in the sorting section 4 to be changed. Since it constantly changes, the sorting performance is remarkably deteriorated, resulting in poor sorting, and the swarf stagnates on the second swing sorting shelves 35, and the stray swarf is discharged and scattered outside the machine while the grains are mixed. Becomes Particularly in a damp culm having a high water content, the second sorting section 4 may become clogged, which may be a factor to hinder the threshing operation itself. Therefore, increasing the wind power of the main Karato 7 may cause a vicious cycle in which the scattering of grains outside the machine also increases. Therefore, in order to deal with these problems, the auxiliary sorting wind from the auxiliary Karamoto 10 is combined with the sorting wind from the main Karato 7, and the second object which drops the No. 2 sorting section 4 by the blowing action from the auxiliary Karato 10 is blown. You can select well.

Further, as described above, the auxiliary Karamoto 10, which is necessary for the selection of the second material, also obstructs the removal of the swing sorting device 5 out of the machine when maintenance of the sorting section 25 occurs. However, at this time, by removing the fastening bolts of the fastening arm 47 of the auxiliary Kara,
Since the auxiliary Karako 10 together with the casing 42 in a cassette state can be easily pulled out of the machine through the insertion / removal hole 44 of the left side plate 43 of the selecting section 25, the swing selecting device 5 can be easily removed from the machine at this point. Can be removed.

Normally, when the auxiliary Karamoto 10 is pulled out of the machine, by removing the drive belt for driving the auxiliary Karamoto 10, the driving of the sorting unit 25 is stopped and it becomes inoperable. In the present invention, the drive of the auxiliary Karako 10 is independently driven by temporarily laying the auxiliary Karamo drive belt 56 on the drive pulley 55 of the auxiliary Karoh 10 via the loose pulley 53. Even when it is not drawn out of the machine, it does not hinder the operation of the parts other than the selecting part 25.

As a result, the auxiliary Karin 10 can also be used as an optional form that can be worn at any time as needed. Also, the auxiliary Kara 10 is interposed between the first gutter 8 and the second gutter 9, and this air outlet is opened so that air can be blown toward the upper surface of the second swing selection shelf 35. Due to this, the rotating direction of the auxiliary Karamoto 10 is inevitably opposite to the direction of action of the main Karaso 7 and other parts, but this problem is that the loose pulley 53 is provided and the loose pulley 53 is connected to the sorting section drive belt. The rotation direction can be easily reversed by driving the belt back surface of 54.

Numeral 57 is a crawler traveling device, numeral 58 is a grain auger of the grain tank 18, and numeral 59 is a cabinet.
