[Problems to be solved by the invention]
However, the threshing machine having the above-mentioned configuration is configured such that the sorted matter in which the grains, the ears, etc. are mixed in the sawdust after filtering the grain in the sorted matter with the filter body is the most in the sorting path. Wind selection is carried out by the selection wind blown upward and rearward from the wind selection gap formed at the end of the filter body and the rear end of the first selection body, and the first selection body located at the wind selection injection portion of this selection is raised. Each standup sorter of the sorter and the second sorter collects and sorts the first and second ones, so the sorting wind is weakened due to fluctuations in the threshing load, etc., and threshing that contains a large amount of sawdust When the product is fed or the amount of threshing is small, the sorting wind passing through the wind sorting gap changes, and the sorted product can be thrown at the proper position. First, it becomes difficult to sort the grains and sawdust in the sorted items by the above-mentioned standing sorting plates. It is easy to frequently mix swarf, and grains etc. are blown away to the second sorter side with the sawdust and the second reduction amount increases, and the reduction sorting load of the second thing becomes larger. There are problems such as frequent grain damage and inability to efficiently perform threshing.

[0008]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, A is a threshing machine that can be mounted on a harvesting machine such as a combiner, and the threshing machine A stretches a feed chain 3 in the front-rear direction along a handling chamber 2 configured in the machine body 1, and ends. After the waste transporting belt 3a is connected to the part, the harvested cereal is supplied to the handling chamber 2 and threshed, and then the processed waste is placed in the waste processing device (cutter) C installed at the rear part of the machine body 1. It is transported and post-processing such as cutting is performed.
[0009]
And the said threshing machine A connects the processing chamber 2c which includes the processing cylinder 20 and the processing net | network 21 to the terminal tip side of the processing cylinder 2a and the processing net | network 2b which comprise the processing chamber 2, and below these, In the sorting air passage F formed by the blower fan 4 and the dust exhaust fan 5 installed at the front and rear, the swing sorting body 6 provided with the first sorting passage 6F and the second sorting passage 6N can swing in the front-rear direction. Aside from the first sorting path 6F of the swing sorting body 6, the first basket 7 for accommodating the first thing in the grain tank 7b via the milled cylinder 7a, and the second sorting path 6N. A second basket 7d for reducing the second product to the swinging sorter 6 through the reduction cylinder 7c is arranged.
[0010]
Further, the dust exhaust fan 5 installed at the rear part of the machine body 1 has an opening portion opened at the rear part between the two machine walls of the threshing machine A in a state where the drum-shaped cross flow fan 52 is housed in the fan case 51. It is installed so as to also serve as a rear wall, and supports one side of the fan case 51 so as to be openable and closable around the vertical axis, and the waste treatment apparatus C is also centered on a vertical axis (not shown) on one side. When the swing sorting body 6 is attached to the side so that it can be opened and removed, and the assembling work is performed, the waste disposal device C and the dust exhaust fan 5 are opened so as to be in a double-spread form, so that the airframe 1 The rear part is widely opened to an obstacle-free state, and the removal and assembling work of the swing sorter 6 from the opened opening and the maintenance work such as the cleaning check in the threshing machine A are easily performed. It is possible.
[0011]
Further, the swing sorter 6 has a front and rear portion having the same configuration as that of the conventional one, and is supported by the support link 10a and the drive mechanism 10 so as to be swingable and detachable. The support state is configured to be able to be released, and the released swing sorting body 6 is slidably placed on guide rails projecting on the inner sides of the left and right machine walls (not shown), and the insertion / removal operation is performed. It is easy to do.
Reference numerals 9 and 9a are flexible flow guide plates that are integrally attached and fixed to the lower rear surface of the first sorting body 63 of the first sorting path 6F and the second sorting body 65 of the second sorting path 6N, respectively. And the lower part formed in the free end is erected separately on the first rod 7 and the second rod 7d.
[0012]
The rocking sorter 6 is a chaff sheave for sorting and transferring sieves by arranging a specific gravity sorting transfer plate 61 having a corrugated transfer surface between the left and right side walls 6a from the front and a slat-like plate-like body arranged at rough intervals. 62, and a filter body 8 made of a crimp net for grain filtering and sorting is stretched below the chaff sheave 62. The chaff sheave 62 and the filter body 8 float the sawdust in the first sorting path 6F. It has a wind-selection space that allows movement, and is arranged in the upper and lower stages.
Further, the swinging sorter 6 includes a first sorter 63 having a configuration to be described later that forms the first sorter path 6F behind the chaff sheave 62 and the filter body 8, and a second sorter path behind the first sorter 63. A second sorting body 65 that forms 6N is provided, and both are provided with a swash plate sorting body 6b described later.
The first sorting body 63 has the rear end portion of the filter body 8 joined, guides the first thing filtered from the filter body 8 down to the first basket 7 and is removed from the chaff sheave 62. The cereals (sorted matter) after the first sorting are thrown into the second sorting body 65 side by the sorting wind while wind sorting.
[0013]
The second sorting body 65 is installed with a wide flat plate-like swash plate sorting body 6b inclined forward and downward at a throwing-out portion of the cereals thrown from the front side of the first sorting path 6F. Due to the difference in the throwing repulsive force between the grain and the sawdust on the body 6b, the grain is sorted and transferred to the front side, and the waste is discharged and transferred to the rear to perform the sorting. It is made to flow down to the second rod 7d and collected, and the dust is transferred to the dust fan 5 side.
[0014]
In addition, the processing chamber 2c is communicated with the rear end (point side) at the end of the processing chamber 2 in the same manner as the conventional one, and the processing cylinder 20 is close to the rear wall 1d of the machine body 1. A processing net 21 provided from the start end side is provided below the outer periphery of the processing cylinder 20, and a dust discharge port 22 is formed at the terminal end side of the processing net 21.
The dust discharge port 22 opens above the rear end portion of the second sorting body 65 and the dust discharge air passage of the dust discharge fan 5 so that the dust discharged from the processing chamber 2c can be discharged. It is prevented from falling directly into the second sorting path 6N.
[0015]
Next, the detailed configuration and operation of the first sorter 63 and the second sorter 65 of the swing sorter 6 will be described.
First, the first sorter 63 has a bent sorter surface 63a in which a middle part in the vertical direction of a single plate-like body placed horizontally between the left and right side walls 6a is bent into a smooth curve, and a grain rest on the upper part. A swash plate selection body 6b having a swash plate selection surface 63b inclined forward and downward with a gentle inclination angle less than the angle, and a flow surface 63c having a steep inclination angle greater than the grain repose angle below the bending selection surface 63a, By forming a series so as to have a substantially square shape when viewed from the side, it is possible to perform the sorting based on the difference in the rocking wind sorting action and the throwing-out repulsion force of the cereals as with the second sorter 65. I have to.
[0016]
Further, a connecting portion P is formed by attaching and fixing the rear end portion of the filter body 8 below the bending selection surface 63a and above the flow surface 63c, that is, at the bending selection end position.
In addition, this transfer part P makes the waste material in a sorting thing to the flow surface 63c side from the swash plate selection surface 63b formed in the extended surface of the selection body 63 and the bending selection surface 63a to the filter body 8 side. It smoothly relays while preventing filtration.
Further, the transfer plate 61 is integrally formed with a partition plate 67 whose rear end is refracted to the front lower side and extended toward the fan case side of the blower fan 4, and the filter body is formed below the partition plate 67. The front end portion of 8 is attached.
[0017]
Therefore, the swing sorting body 6 in the illustrated example forms the first sorting path 6F by the partition plate 67 and the first sorting body 63 and accurately sends the sorting wind in the rectified state in the sorting transfer direction (backward and upward). The filter body 8 is stretched over the entire lower surface of the sorting path 6F, and the chaff sheave 62 is installed above the filter body 8 with a predetermined wind selection space. By doing so, the sawdust is leaked from the flow-down gap formed by the end of the filter body 8 and the first sorting body 63 as in the prior art, and enters the most 7 side through the flow surface 63c. This is precisely prevented.
8a is a rectifying plate that uniformly guides the selected air from the blower fan 4 over the entire surface of the filter body 8, and is inclined so as to be directed toward the blower fan 4 from the lower part of the front and rear of the filter body 8.
[0018]
Further, the chaff sheave 62 in the embodiment has a complicated structure such as rotating each sheave plate 62a and adjusting the scale as in the conventional case because threshing is favorably sorted by the sorting structure as described above. Without using a filtration amount adjustment type threshing machine equipped with a filtration amount adjustment mechanism of the structure, a chaff sheave structure of a constant filtration amount type in which each sheave plate 62a is fixed to a scale of about the standard to approximately the maximum filtration amount. It is something that can be done.
In addition, a swarf discharge air passage H having a relatively large gap, in which a plurality of sheave plates 62a are omitted, is formed between the end of the chaff sheave 62 at the front of the bent sorting surface 63a of the first sorter 63, The sawdust discharge air passage H is a sorting wind that passes through the filter body 8 as shown in FIG. 2 and quickly throws and discharges the sawdust and spikes filtered from the chaff sheave 62. To be able to.
As a result, it is possible to omit a complicated chaff sieve adjustment operation at the time of threshing work, and it is possible to make the configuration of this part extremely simple and to reduce the weight of the swing sorter 6.
[0019]
On the other hand, the second sorting body 65 laid laterally between the left and right side walls 6a behind the first sorting body 63 is bent in the same way as the first sorting body 63 by bending the upper halfway portion of the single plate-like body. A sorting surface 65a is formed, and a swash plate sorting body 6b formed on a wide flat plate-like swash plate sorting surface 65b is installed on the top of the sorting surface 65a so as to incline forward and downward to the throwing part of the cereal crop thrown from the first sorting path 6F. At the same time, a steeply inclined flow surface 65c that guides the second object to flow down to the second rod 7d is formed in a lower part of the bending selection surface 65a in a series of letter-shaped shapes when viewed from the side.
The swash plate selection surface 65b is positioned below the dust discharge port 22 of the processing chamber 2c as described above to form a dust discharge air passage with the rear wall 1d, and is the most selected. This is a book that will be described in detail below with a swash plate selection surface 65b that is inclined forwardly and downwardly at the falling point of the selected object thrown by the selection wind from the road 6F side, that is, the wind selection anchoring part. According to the sorting method of the invention, the second object is recovered through the flow surface 65c to discharge the sawdust.
[0020]
The swash plate sorting surface 65b receives and removes dust particles containing grains discharged from the front side of the dust outlet 22 and swings and sorts the grains discharged from the terminal end of the dust outlet 22. Dust that does not contain particles can be quickly transferred to the dust fan 5 side without being caught by the swash plate sorting surface 65b, and discharged well with the sawdust after the second sorting. I can do it.
The swash plate sorter 6b has its swash plate sorting surface 65b to move the grain to the front side according to the difference in the throwing repulsive force between the grain and the sawdust, and to discharge and transfer the sawdust to the rear. The swash plate sorter 6b is arranged so that the front part of the swash plate sorter 6b is provided at a position lower than the rear part of the sorter 63 and is less than the repose angle of the grain. I have to.
[0021]
In the threshing machine A configured as described above, when threshing is performed in the handling chamber 2 and the processing chamber 2c, grains and small swarfs are screened by the handling net 2b and the processing net 21 etc. In response to this, the oscillating sorter 6 receives this and performs oscillating motion and oscillating wind sorting action by the sorting wind. Then, the first sorter 63 accommodates it in the grain tank 7b through the first basket 7 and the milled cylinder 7a.
[0022]
And, long swarfs such as chopped rice cakes, and sorts such as grains and spikes mixed therein are passed through the chaff sheave 62 and the bent sorting surface 63a of the first sorting body 63 and the swash plate sorting surface 63b. While sorting, it is thrown and transferred toward the second sorting path 6N, sorted by the second sorting body 65, and the second thing is swung from the second sorting body 65 through the second basket 7d and the reducing cylinder 7c. 6 is transferred to the transfer plate 61 and re-sorted.
In addition, the sorted dust that is sent from the swing sorter 6 side and the dust that is discharged from the dust outlet 25 of the processing chamber 2 c are sorted by the blower fan 4 and the dust fan 5. The air is sucked by the dust exhaust fan 5 and guided along the rear wall 1d and the rear wall of the fan case 51, and is quickly sucked and discharged by the dust exhaust fan 5 toward the outside of the apparatus.
[0023]
In performing the threshing sort as described above, the first sorter 63 that performs a swinging motion with a substantially elliptical trajectory in the front-rear direction is provided with the filter body 8 through the relay part P in the middle, and thereafter Since the end extends long at a position substantially higher than or slightly higher than the chaff sheave 62 installed above the filter body 8 at the rear upper side from the position of the transfer portion P of the filter body 8, The selected material fed from the chaff sheave 62 and the processing net 21 on the extended surface and the selected material that is wind-selected and transferred on the filter body 8 are joined together to form the selected material on the extended surface. In this way, it is possible to satisfactorily carry out the stay sorting by the first sorter 63, while performing the swaying wind sorter while loosening over a sufficient stay time.
[0024]
In the swash plate sorting surface 63b, the cereal thrown from the filter body 8 and the chaff sheave 62 side by the sorting wind is also sorted using the throwing repulsion force of the sorting object in the same manner as the sorting method using the second sorting body 65 described later. Since the method is received, it is possible to satisfactorily reselect the grains that are to be thrown backward without filtering the filter body 8, and during this time, it is possible to promote the rapid recovery of the grains. it can.
Therefore, it is possible to appropriately throw and transfer the sorted matter with less grain contamination to the second sorted body 65 side, so that the sorted product remains in the form of a nodule on the second sorted body 65 side. Since it is not transported in large quantities, it is possible to favorably recover and reduce the second product with reduced contamination of the sawdust without excessively increasing the sorting load on the second sorting body 65. .
[0025]
At this time, the extended surface of the first sorting body 63 is formed with the end of the chaff sheave 62 and the swarf discharge air passage H having a sufficiently wide area where the sheave plate 62a is not installed. In the inside, the chaff sheave 62 installed with the wind selection space above the filter body 8 is subjected to wind selection in the wind selection space and discharged toward the upper rear, Without impeding the discharge of the sorted matter including the cutting of the ears and the like, it is quickly discharged and transferred to the rear swash plate sorting surface 63b side through the sawdust discharge air passage H.
Therefore, while preventing clogging of the filter body 8 due to the stagnation of the sawdust in the sorting space and filtering of the scraps, it is possible to accurately filter the grain and the first sorter Grains and the like that slide down from the swash plate sorting surface 63b formed by the extended surface of 63 are smoothly transferred to the filter body 8 side while preventing clogging of the sawdust discharge air passage H and the like, and accurately filtered, It is possible to prevent the waste (such as short cutting scraps) in the first item from being mixed and recover it well.
[0026]
Further, the chaff sheave 62 has a complicated structure such as rotating each sheave plate 62a to adjust the scale as in the conventional case, since the cereal is well sorted by the sorting structure as described above. Without using a rocking sorter equipped with a filtration amount adjusting mechanism, a fixed filtration amount type chaff sheave structure in which the mesh of each sheave plate 62a is fixed can be obtained. Each time of threshing or threshing the wet cereal, it is possible to omit a complicated operation of adjusting the scale of the chaff sheave and to simplify the structure of the chaff sheave 62 so as to reduce the weight of the rocking sorter 6. In addition, there is an advantage that a high-efficiency and inexpensive threshing machine A can be provided.
[0027]
Next, a sorting method in the second sorter 65 will be described. The second sorting body 65 is moved forward and downward below the repose angle of the grain through a bent sorting surface 65a positioned so as to be lower than the rear end of the swash plate sorting surface 63b of the first sorting body 63. Since the swash plate sorting surface 65b having a gentle slope and the steeply sloping flow surface 65c are integrally formed, the sorting object thrown out by the sorting wind from the sorting path 6F is the dust fan 5 side. The second product is separated by a sorting method in which it is once received by the swash plate sorting surface 65b without being directly discharged and transferred, and then sorted according to the difference in the repelling force between the grains and the sawdust. In addition to collecting and transferring to the number sorting path 6N side, the sawdust is discharged and transferred rearward to be accurately discharged from the dust fan 5 to the outside of the machine.
[0028]
That is, in the above-described sorting method, the wide plate-like body is formed in the wind sorting anchoring portion of the threshing by the sorting wind in the sorting air passage F in which the threshing is thrown upward and rearward by the sorting wind. The swash plate sorting surface 65b is provided so as to tilt forward and down below the angle of repose of the grain, and the grain is returned to the front side due to the difference in throwing repulsion force on the swash plate sorting surface 65b. As shown in FIG. 3, it is thrown from the first sorting path 6F and the rear end of the first sorting body 63 with a substantially parabolic trajectory. The grain has a specific gravity and hardness greater than that of sawdust, and the surface area is small and small. Therefore, the grain surely falls to the wind selection anchoring part of the swash plate selection surface 65b, and the repulsion coefficient of the grain with inertia is low. Due to the throwing repulsive force, the swash plate selection surface as shown by the dotted line in the figure 5b once jumps upward and slightly rearward, but it can be accurately shifted to the front side while gradually attenuating the jumping by the front and lower inclined surfaces, and is second through the bend selection surface 65a and the flow surface 65c. 7d is recovered well.
At this time, the sorting wind directly above the swash plate sorter 6b is weaker than above, and the surface area of the grain is small, so that the grain is not hindered from moving forward by this sorting wind. is there.
[0029]
As shown in FIG. 4, the sawdust is thrown from the first sorting path 6F in the same way as the grain. Among these, the light sawdust, the long sided rice cake, etc. are the swash plate sorting surface 63b and the swash plate. By receiving a large amount of sorting wind that flows in a strong wind while detouring along the machine wall side above the sorting surface 65b, the dust collecting fan 5 passes over this without falling to the swash plate sorting surface 65b. The long rice cake (cutting rice cake) in the sawdust that is directly discharged and thrown in the vertical direction is thrown and dropped onto the swash plate sorting surface 65b without being greatly blown off by the sorting wind. However, since such a long koji has a small throwing repulsive force compared to the grain, it does not jump up greatly, and while being in a lifted posture in a state where it has been slightly bounced and lifted up on the swash plate sorting surface 65b, throwing inertia Empowered Masono undergoing sorting wind a large surface area, since the discharge shifts to the rear to slide on the swash plate sorting surface 65b, are intended to be carried out satisfactorily the outside emissions from dust-exhaust fan 5.
[0030]
Then, when performing the sorting method as described above, if the swash plate sorting surface 65b is swung in the front-rear direction as in the illustrated example, the grain is moved to the front side by the swinging motion. Therefore, there is an advantage that the second product can be recovered more quickly.
Further, the swash plate sorting surface 65b of the wide swash plate sorter 6b having a forward and downward slope imparts a good loosening action by a swinging motion while retaining grains, spikes and the like mixed in the sawdust. Therefore, there are advantages such as being able to promote the retention selection while accurately separating the grains, cuttings of the ears, etc. and the wastes, and to successfully recover the second product with reduced contamination of the wastes. is there.
The sorting method as described above is similarly performed on the swash plate sorting surface 63b of the swash plate sorting body 6b provided in the first sorting body 63 described above.
[0031]
Therefore, the threshing machine A equipped with the threshing sorting method and the sorting structure according to the present invention can reduce the contamination of sawdust in the second product, and therefore, from the second basket 7d to the reduction cylinder 7c. Since the reduction amount of the second product reduced to the transfer plate 61 can be reduced, the second product is repeatedly reduced without overloading the specific gravity selection by the transfer plate 61 and hindering the selection. Therefore, there are advantages such as prevention of troubles such as grain damage and clogging in the reduction route, and accurate selection can be performed smoothly while reducing the threshing load.
[0032]
Further, in the illustrated example, the second sorting body 65 is shown in which the swash plate sorting surface 65b and the flow surface 65c are integrally formed via the bending sorting surface 65a. However, the present invention is not limited to this, and the dotted line in FIG. As shown, the swash plate selection surface 65b and the flow surface 65c may be divided.
That is, the swash plate sorting surface 65b side as the swash plate sorting body 6b is provided integrally with the swing sorting body 6, and the flow surface 65c has a steep inclination angle from the lower side of the swash plate sorting surface 65b and the airframe 1 In this case, since the side wall 6 for providing the flow surface 65c can be reduced, the structure of the rocking sorter 6 can be simplified and reduced in size and weight. There is an advantage that it can be achieved.
When the swash plate sorter 6b is separated from the swing sorter 6 and is fixed to the machine body 1, the swash plate sorter 6b collects and forwards the grains forward by the throwing repulsion force. What is necessary is just to provide it with a necessary inclination angle.
[0033]
Further, as shown in FIG. 2, the filter body 8 has a configuration in which the end thereof is in contact with and supported by the flow surface 63 c of the first selection body 63. Is provided with a guide plate 63d as shown by the dotted line in the drawing, and the sorted material flowing down from the extended surface is provided on the filter 8 side. The first sorting body 63 and the filter body 8 may be connected to each other so that the first sorting body 63 and the first sorting body 63 are disposed between the rear end of the filter body 8 and the first sorting body 63, as in the prior art. It may have a gap.
In the illustrated example of the chaff sheave 62, the sheave plate 62a is fixed. However, the present invention is not limited to this.
[0034]
Further, as shown in the figure, the second sorting path 6N is provided with a blow hole 7f for introducing outside air at the lower portion thereof, so that the second sorting path 6N is sucked by the sorting wind into the second sorting path 6N and moves upward from below. A directional sorting wind is formed, and small swarf and dust are discharged from the machine by this sorting wind. However, even if an auxiliary blower fan is provided in this part to forcibly blow the sorting wind, In addition, a Strollac 6c may be provided on the upper portion of the second sorting path 6N, for example, as shown by the dotted line in FIG.
[0036]
【The invention's effect】
  The present invention has the following effects by using the cereal grain sorting structure as described above.
  A swing sorting body provided with a chaff sheave and a filter in the first sorting path formed by the first sorting body in the sorting air channel below the handling chamber is supported so as to be swingable in the front-rear direction, and A second sorting body is provided behind the sorting body, and a wide flat plate-shaped swash plate sorting body is moved forward and downward to the throwing part of the second grain sorting body thrown from the first sorting path.LooseDifference in throwing and repulsive force between grains and sawdust on the swash plate sorterAnd sorting windTo move the grain to the front sideon the other handSorted items thrown out by the sorting wind from the first sorting path by adopting a threshing sorting structure in which the wastes are discharged and transferred to the rear.TheDifference in grain repulsion force between grains and sawdust received by the above swash plate sorterAnd sorting windTo collect and transfer the second item to the second sorting roadon the other handSince the wastes are discharged and transferred to the rear and discharged accurately, the contamination of the wastes can be reduced in the second product, and the reduction amount of the second product can be reduced. Therefore, there is an advantage that it is possible to smoothly perform accurate sorting that prevents troubles such as grain damage and clogging in the reduction route.
[0037]
Further, by providing the front part of the swash plate sorter of the second sorter at a position lower than the rear part of the first sorter, the sort thrown from the first sorter can be accurately placed on the swash plate sorter. It can be received and the grain and sawdust can be selected well.
[0038]
Furthermore, by swinging the swash plate sorter of No. 2 sorter, it is good by rocking motion while retaining grains and spikes etc. mixed in the sawdust on the swash plate sorter. Since the unraveling action is imparted, it is possible to accurately separate the grains, the stalks, etc., and the wastes, and to recover the second product with reduced contamination of the wastes.
