Abstract

<P>PROBLEM TO BE SOLVED: To effectively recover grains contained in ear-cut products while not only preventing a threshing treatment capacity from being reduced by the retention of the ear-cut products in a threshing chamber but also preventing the selection action of the first product by a chaff sieve mechanism from being deteriorated without causing the increase of a cost and enlargement of a size. <P>SOLUTION: The swinging selection structure has a swinging selection mechanism including the chaff sieve mechanism and a re-selection mechanism integrally swung in the front and rear direction of a machine body, and is constituted so that the first product selected by the chaff sieve mechanism may leak down to a first product gutter and the second product selected by the re-selection mechanism may leak down to a second product gutter. The swinging selection structure is also equipped with a bypass mechanism for conveying at least a part of a waste including a threshed product and an unnecessary substance discharged from a waste-sending opening installed in the downstream side of the threshing chamber in the grain culm-conveying direction in the threshing part to the re-selection mechanism by bypassing the chaff sieve mechanism. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a swing sorting structure applied to a combine.

  Arranged along the longitudinal direction of the fuselage so that the threshing part that performs the threshing process on the cereals conveyed by the feed chain device and the threshing threshed by the threshing part are aggregated respectively. Conventionally, it is known to adopt a swing sorting structure including a chaff sheave mechanism and a strola back mechanism that swings integrally in the longitudinal direction of the machine body in a combine including the first and second hooks. For example, see Patent Document 1 below).

Specifically, the threshing unit includes a handling chamber and a handling cylinder that is driven to rotate about a rotation axis in the handling chamber, and a tooth treatment provided on the handling cylinder acts on the tip side of the cereal. It is comprised so that the threshing containing a grain may be made to detach | leave from a grain cocoon.
The threshing leaks downward from the handling chamber via a receiving net disposed below the handling chamber, and is provided directly to the chaff sheave mechanism or upstream of the chaff sheave mechanism in the grain conveying direction. It is supplied to the chaff sheave mechanism through a feed pan.

The chaff sheave mechanism sorts a part of the threshing that is sent from the feed pan and / or the threshing that directly leaks from the threshing part as the first thing, and causes the first culvert to leak. It is configured.
The Strollack mechanism is disposed downstream of the chaff sheave mechanism in the grain conveying direction, sorts out the cereals sent from the chaff sheave mechanism into second and unnecessary items, and sets the second item as the second item. It is configured to allow the bag to leak and to discharge unnecessary items such as waste to the outside of the machine.

By the way, in the threshing process of the threshing part, a phenomenon occurs in which the tip side of the cereal bud is divided from the stock source side (hereinafter, the tip side divided from the stock source side is referred to as a spike piece).
Among the cut pieces, those smaller than the opening width of the receiving net pass through the receiving net together with the threshing portion containing the grain and leak downward, but among the cut pieces, those larger than the opening width are the above Stay in the handling room.
Pieces of spikes staying in the handling chamber are rotated by the handling cylinder and entangled with each other toward the downstream side in the grain conveying direction to form a lump. Such a lump of spikes deteriorates the threshing efficiency of the threshing portion and causes a power loss with respect to the driving force of the barrel.

  In this regard, a dust feeding port is provided on the downstream side of the handling chamber in the grain transporting direction, and the cut pieces discharged through the dust feeding port are subdivided by a dust feeding port processing cylinder different from the handling cylinder. Therefore, a configuration (hereinafter referred to as a dust removal processing structure) that allows the chaff sheave mechanism and / or the Strollac mechanism to leak is proposed (see, for example, Patent Document 2 below).

  The dust disposal structure is effective in that it can prevent the inconvenience that the spiked material stays in the handling room and deteriorates the threshing treatment efficiency, and can effectively recover the grains contained in the spiked material, In addition to the handling cylinder, there is a problem in that the dust feeding port processing cylinder is provided, resulting in high cost and large size.

It is also possible to provide the dust feeding port in the handling chamber without providing the dust feeding port processing cylinder, and let the cut piece leak onto the chaff sheave mechanism through the dust feeding port. Although it is possible to prevent stagnation of spikes, according to this structure, in addition to the cereals that the chaff sheave mechanism passes directly through the receiving net or through the feed pan, the dust feeding port This also sorts off the spikes that are being sent through the chaff, so that the sorting process in the chaff sheave mechanism may overflow.
When the chaff sheave mechanism overflows, the first thing sorting action for sorting the first thing from the threshing is reduced, and the grain recovery efficiency is deteriorated.

  As described above, in the present embodiment, the swing sorting structure 200 includes the bypass mechanism 260, thereby preventing deterioration of the threshing processing efficiency in the threshing unit 100, and by the chaff sheave mechanism 230. The grain recovery efficiency is improved while preventing the deterioration of the first thing sorting action.

  That is, at the time of the threshing process in the threshing unit 100, the tip side of the cereal husk is divided from the stock source side, and a spiked piece is generated in the handling chamber 120. Of these cut pieces, the one larger than the opening width of the receiving net stays in the handling chamber 120 and is rotated by the handling cylinder 130, and finally becomes solid on the rear side of the machine body of the handling chamber 120. It becomes a shape. Such lump-like spikes deteriorate the threshing efficiency of the threshing unit 100 and cause power loss with respect to the driving force of the barrel 130.

  On the other hand, according to the oscillating sorting structure 200 including the bypass mechanism 260, the threshing of the threshing unit 100 is caused by the accumulation of spikes in the handling chamber 120 without increasing the cost and increasing the size. It is possible to prevent the inconvenience that the processing efficiency is deteriorated and to effectively recover the grains contained in the cut pieces while preventing the deterioration of the first object sorting action by the chaff sheave mechanism 230.

FIG. 10 shows a process flow diagram of the swing sorting structure 200 provided with the bypass mechanism 260.
As shown in FIG. 10, threshing smaller than the opening width of the receiving net 140 among the threshing threshed by the threshing unit 100 is sent to the chaff sheave mechanism 230 via the feed pan 220 or directly.

As described above, the chaff sheave mechanism 230 selects a part of the threshing portion as the first thing and causes the first mash 51 to leak. Then, the first item collected in the first basket 51 is conveyed to the Glen tank 6 via the first conveyor 11 and the cereal conveyor 12.
The chaff sheave mechanism 230 causes a part of the cereals that have not been selected as the first item to leak to the second basket 52 as the second item, and supplies the remainder to the re-sorting mechanism 240.
Further, as in the present embodiment, when the grain sheave mechanism 250 is provided, a part of the first thing selected by the chaff sheave mechanism 230 is carefully selected by the grain sheave mechanism 250, and the second As a product, it can be leaked into the second basket 52.

On the other hand, the trash that has been threshed by the threshing unit 100 and the dust that includes the cut pieces produced by the threshing unit 100 are supplied to the bypass mechanism 260 through the dust feed port 121.
The bypass mechanism 260 supplies the dust to the upstream side in the transport direction of the re-sorting mechanism 240 in a state where the chaff sheave mechanism 230 is bypassed.
The re-sorting mechanism 240 sorts out the dust that has a large specific gravity including the grain as a second thing and causes the second toe 52 to leak and eliminates the need for waste or the like in the dust. Items are transported outside the machine.
The re-sorting mechanism 240 performs sorting of the second thing from the cereals sent from the chaff sheave mechanism 230 in addition to the second thing from the dust.

  The second item selected from the cereal by the chaff sheave mechanism 230, and the second item selected from the cereal by the re-sorting mechanism 240 and the second item selected from the dust are all the second item. 52 and returned to the swing sorting mechanism 210 (in the present embodiment, the feed pan 220) in a state of being subdivided by the second processing mechanism 65, and again by the swing sorting mechanism 210. Receive the sorting process.

As described above, in the present embodiment, the dust discharged including the spiked material in the handling chamber 120 is discharged from the handling chamber 120 through the dust feeding port 121, and the dust is discharged from the handling chamber 120. The re-sorting mechanism 240 is supplied by the bypass mechanism 260.
Therefore, it can prevent that the said waste material stays in the said handling chamber 120, and can prevent effectively that the threshing processing efficiency of the said threshing part 100 deteriorates by presence of the said waste material.
Furthermore, since the dust is not supplied to the chaff sheave mechanism 230, the sorting ability of the chaff sheave mechanism 230 is not reduced by the dust.
In addition, since the dust is subjected to the second sorting action by the re-sorting mechanism 240, the dust having a large specific gravity including grains is positioned below the re-sorting mechanism 240 as a second thing. Are collected in the second basket 52 and returned to the swing sorting mechanism 210 in a state of being subdivided by the second processing mechanism 65. Therefore, the recovery efficiency of the grains contained in the dust can be effectively improved.

Preferably, the bypass mechanism 260 is configured to swing integrally with the swing sorting mechanism 210 in the grain transporting direction.
By providing such a configuration, it is possible to transport the dust to the re-sorting mechanism 240 using the rocking operation of the rocking-sorting mechanism 210.

In the present embodiment, as shown in FIGS. 8 and 9, the bypass mechanism 260 has a substantially horizontal posture above the chaff sheave mechanism 230 so as to receive dust discharged from the dust delivery port 121. A bottom plate 261 extending in the front-rear direction of the body, and a side plate 262 extending upward from the other end of the bottom plate 261 in the body width direction and forming a bypass passage under cooperation with the bottom plate 261, A bottom plate 261 is operatively connected to the swing sorting mechanism 210 so as to swing in the longitudinal direction of the machine body in conjunction with the swing operation of the swing sorting mechanism 210.
That is, in the present embodiment, substantially all of the dust discharged from the dust feeding port 121 is conveyed to the re-sorting mechanism 240 via the bypass passage defined by the bottom plate 261 and the side plate 262. Is configured to do.
Note that one side of the bypass passage in the body width direction is defined by, for example, a swinging side plate 215 (in this embodiment, a swinging side plate on the right side with respect to the forward direction of the body) positioned on one side in the body width direction. Is done.
Naturally, instead of such a configuration, another side plate extending upward from one end of the bottom plate 261 in the body width direction is provided, and the bypass passage is defined by the bottom plate 261, the side plate 262, and the other side plate. It is also possible to do.

Alternatively, the bypass mechanism 260 may be configured to convey the dust discharged from the dust delivery port 121 to the re-sorting mechanism 240 while sorting.
In such a case, the bypass mechanism 260 may include a plurality of fins (not shown) similar to the plurality of chaff fins 231 in the chaff sheave mechanism instead of the bottom plate 261.
In other words, the bypass mechanism 260 may include a plurality of fins extending in the vehicle width direction and arranged in parallel in the vehicle front-rear direction with a space therebetween, instead of the bottom plate 261. In such a bypass mechanism having a plurality of fins, part of the dust is subjected to specific gravity sorting and leaked to the lower chaff sheave mechanism 240, and the remainder of the dust is transported to the re-sorting mechanism 230. .
In such a configuration, by setting the fin installation interval in the bypass mechanism to be smaller than the chaff fin installation interval, much of the dust can be conveyed to the re-sorting mechanism 240.
The plurality of fins are in a rear-inclined state in which a lower end portion is located on the front side of the airframe with respect to the upper end portion, and are preferably swingable integrally around a pivot shaft along the vehicle width direction.
By providing such a configuration, the opening width of the interval can be adjusted by changing the inclination angle by a drive mechanism (not shown).

In the present embodiment, as described above, the handling cylinder 130 is arranged along the longitudinal direction of the machine body so that the handling teeth 135 pass from the top to the bottom with respect to the cereals conveyed by the feed chain device 20. It is rotated around the barrel drive shaft 131.
In order to discharge the dust using the rotational movement of the handling cylinder 130, the dust feeding port 121 has the feed chain sandwiching the handling cylinder 130 among the side walls forming the handling chamber 120. It is provided on one side in the body width direction opposite to the device 20.

  Therefore, in the present embodiment, as shown in FIGS. 8 and 9, the bottom plate 261 is disposed so as to be positioned above the chaff sheave mechanism 230 on one side in the body width direction of the chaff sheave mechanism 230. .
