Therefore, the lower partition plate (55b) can be provided to a height near the axis of the handling cylinder (18), and the handling chamber (15) and the small grain recovery chamber (56) can be sufficiently partitioned.

  The invention of this application will be described in detail below with reference to embodiments, but mainly relates to a swing sorting shelf 3 that is freely swingable in the sorting chamber 2 of the threshing machine 1. Is provided to preliminarily sort out cereals that have leaked from the handling chamber 15 or the like. The presieve 5 sorts the grains that have been made into one grain at a time, greatly reduces the total amount of cereals (subjects) to be sent to the subsequent chaff sheave 6, and reduces the sorting burden of the chaff sheave 6. Even when the threshing process is made highly efficient, the sorting accuracy of the chaff sheave 6 is increased, and the amount of grains mixed in the second and dusty substances is reduced as much as possible to reduce the loss outside the machine.

  The pre-sheave 5 is not provided at the rear end portion of the transfer shelf, and does not reduce the sorting area of the chaff sheave 6. Compared with the chaff sheave 6, the sorting pitch between the sheave plates (first sheave plates) is narrowed. The plate width is also shortened to make it extremely compact.

In this way, the present invention provides a high-performance threshing machine by increasing the processing capacity and sorting accuracy of the threshing machine, reducing the scattering of the grains outside the machine.
Hereinafter, an example is described concretely based on a drawing.

  First, as shown in FIG. 5, the threshing machine 1 is configured such that a handling chamber 15, a second processing chamber 16 and a dust removal processing chamber 17 are provided on the upper side, and a sorting chamber 2 is disposed on the lower side. . As shown in the drawing, the handling chamber 15 is provided with a handling cylinder 18 mounted in the longitudinal direction, and a handling port for inserting the ear part of the cereal into the handling chamber 15 on the front side of the handling cylinder 18. 21 (see FIG. 3) is open along the longitudinal direction. The handling cylinder 18 is provided with a large number of teeth 19, 19 on the outer periphery as is well known in the art. In this case, the threshing action and threshing of the handling chamber 15 are carried out as the teeth 19, 19 rotate. The structure is arranged so as to give the function of sending dust to the lower side.

  As shown in FIGS. 3 and 5, the culm clamping / conveying device 20 is arranged on the outer side of the mouthpiece 21 along the conveying direction of the culm, with the clamping jar 20 a on the upper side and the feed chain on the lower side. 20b is provided, and the stocker side of the cereal is sandwiched from above and below and the tip side is conveyed while threshing in a state of being inserted into the handling chamber 15 from the handling port 21.

  As shown in FIG. 5, the sorting chamber 2 is provided with a swing sorting shelf 3 on the upper side so as to swing freely along the sorting direction of grain removal. The swing sorting shelf 3 is configured by arranging the transfer shelf 4, the pre-sheave 5, the chaff sheave 6, and the stroll back 7 in this order from the upper side in the sorting direction. In the case of the embodiment, as shown in FIG. 5, the front transfer shelf 4, the pre-sheave 5, and the start end portion of the chaff sheave 6 are disposed below the handling chamber 15 and the second processing chamber 16. It is configured. In addition, the chaff sheave 6 has a configuration in which the start end portion is located below the communication path 23 to the dust removal treatment chamber 17 at the end portion of the handling chamber 15. The pre-sheave 5 is compared with the chaff sheave 6 disposed on the lower side (selecting direction) thereof, as shown in FIG. 1, the selecting pitch P between the sheave plates (first sheave plates) 5a, 5b, 5c. Is made small and the vertical width H is also shortened.

  As shown in FIGS. 1 to 3, the pre-sheave 5 is pivoted with an upper pivot fulcrum pin (first pivot fulcrum pin) 8 attached to the side portion of each sheave plate 5a, 5b, 5c. The lower connection pin (first connection pin) 10 attached to connect to the connection plate (first rotation connection plate) 9 is configured to be inserted into the pin holder 24, and in this case, the rotation support point. The pin 8 and the connection pin 10 are configured in a U-shape integrally formed by bending a single steel material as a raw material. As shown in FIGS. 1 to 3, the pre-sheave 5 is provided with a pivot fulcrum hole 25 on the upper side and an adjustment long hole 26 on the lower side on the side plates 3 a and 3 b on both sides of the swing sorting shelf 3. The selection pitch P can be selected and adjusted by adjusting the inclination angle through the connection pin 10 connected to the rotation fulcrum pin 8 and the rotation connecting plate 9 respectively.

And in the case of an Example, as shown in FIG. 1, the rotation connection board 9 is set as the structure which can adjust movement with the lock screw 27 which can be fastened and loosened.
Next, as shown in FIG. 1 and FIG. 4, the chaff sheave 6 is a rotation fulcrum pin (second rotation fulcrum pin) provided at a side end portion of each sheave plate (second sheave plate) 6 a, 6 b, 6 c. 11 and a connection pin (second connection pin) 12 are attached as an integrated structure above and below the attachment support portion 13 by molding a resin material. In this case, as shown in FIG. 4, the mounting support portion 13 is configured to be inserted and connected to the side end portions from both sides of each sheave plate 6 a, 6 b, 6 c to attach the upper and lower pins 11, 12.

  The pivot fulcrum pins 8 and the connection pins 10 attached to the sheave plates 5a, 5b, 5c of the pre-sheave 5 are the pivot fulcrum pins (second pivot fulcrum) of the sheave plates 6a, 6b, 6c of the chaff sheave 6. Since the pin diameter is smaller than the pin diameter (a) of the (pin) 11 and the connection pin 12, and the resin material is not suitable in terms of strength, the steel material is used as described above.

  As described above, the pre-sheave 5 is arranged on the upper side in the sorting direction of the chaff sheave 6 so that the cereals sent from the transfer shelf 4 can be pre-sorted. Therefore, it is possible to select the grains that have already been crushed and become single grains and separate them downward, thereby reducing the total amount of the objects to be sorted. Therefore, the chaff sheave 6 is less likely to be burdened with excessive sorting as in the prior art, and can perform the sorting action while fully exhibiting the original sorting ability. In addition to the sorting efficiency, the sorting accuracy is greatly improved. Could be improved.

  In the case of the embodiment, since the pre-sheave 5 is provided at a position corresponding to the rear end portion of the conventional transfer shelf, the pre-sieve 5 that performs pre-sorting as described above does not narrow the sorting area of the chaff sheave 6. As a result, the burden on the chaff sheave 6 can be greatly reduced, and the sorting accuracy of the swing sorting shelf 3 as a whole can be improved.

  In the case of the embodiment, when the pre-sheave 5 is compared with the chaff sheave 6, as shown in FIG. 1, the vertical length (width) of the sheave plates 5a, 5b, 5c is shortened and the selection pitch P is narrowed as a whole. 2 and 3, the adjustment length of the rotation support hole 25 and the connection pin 10 that are opened in the side plates 3 a and 3 b of the shelf 3 that receives the rotation fulcrum pin 8, as shown in FIGS. 2 and 3. Since the hole 26 can be narrowed and a large hole is not required, there is an advantage that the side plates 3a and 3b can be kept strong and can be made compact as a whole.

  Furthermore, as shown in FIG. 4, the chaff sheave 6 of the embodiment is formed by integrally molding the pins 11 and 12 on the upper and lower sides of the mounting support portion 13 made of a resin material. There is also a feature that can be produced at low cost. As described above, the pre-sheave 5 has a thin wire diameter between the pivot fulcrum pin 8 and the connection pin 9, and is not suitable in terms of strength by means of molding from a resin material. When the wire is manufactured by bending), sufficient strength can be ensured even if the wire diameter is thin, so that the adjustment can be performed smoothly without any trouble in terms of durability and adjustment operation.

  As shown in FIGS. 1 and 4, the chaff sheave 6 is pivotally attached to both side plates 3 a, 3 b of the swing sorting shelf 3 so that the upper rotation fulcrum pin 11 can rotate freely, and the lower connection The pin 12 is connected to a rotary connecting plate (second rotary connecting plate) 31 through the adjustment long hole 30, and the rotary connecting plate 31 is connected to a rotary arm 32 and an adjustment wire 33 to adjust the angle. (Selection interval adjustment) is possible.

  As described above, the chaff sheave 6 of the embodiment is configured to perform the angle adjustment separately from the pre-sheave 5 as shown in FIGS. 1, 2, 3, and 5, so When the grain flow rate is small, it is possible to select the seeds by closing the pre-sheave and opening the chaff and letting it leak. Can be increased and sufficient preliminary sorting can be performed, and the burden of sorting the chaff sheave 6 can be reduced.

  And, as shown in FIG. 5, the threshing machine 1 has a cleaning port 35 in the side plate on the feed chain 20b side, so that the sheave plate 5a is operated by operating the lock screw 27 of the pre-sheave 5. , 5b, 5c can be adjusted.

Next, an embodiment is described in which the pre-sheave 5 and the chaff sheave 6 can be integrally adjusted by an interlocking configuration which will be described later, and the adjustment operation is simplified.
In this case, as shown in FIG. 6, the pre-sheave 5 and the chaff sheave 6 are configured so as to be capable of interlocking adjustment by connecting both rotary connecting plates 9 and 31 with an interlocking rod 37. As shown in FIG. 6, the interlocking rod 37 is provided with a plurality of adjustment holes 38 a, 38 b, 38 c, and the relative angle relationship between them can be adjusted by inserting / removing the engagement pin 39. ing.

In addition, this adjustment operation can be performed by opening the cleaning port 35 opened in the side plate of the threshing machine 1 already described.
Then, as shown in the operation diagram of FIG. 7, the pre-sheave 5 and the chaff sheave 6 are connected by an interlocking rod 37 and adjusted from the outside via the chaff-side turning arm 32 and the adjusting wire 33. Both sheave plates 5a, 5b, 5c, 6a, 6b, 6c are simultaneously interlocked via the moving connecting plates 9, 31 to adjust the angle. At that time, as shown in FIG. 7, the rotation angle θ1 of the sheave plate 5a on the pre-sheave 5 side is larger than the rotation angle θ2 of the sheave plate 6a on the chaff sheave 6 side, and the adjustment range of the opening is increased. It has become.

  When the pre-sheave 5 and the chaff sheave 6 configured as described above are subjected to the sorting operation by adjusting the selection pitch and changing the selection pitch, the pre-sheave 5 is always extremely closed and extremely open compared to the chaff side. However, even if it is open or conversely closed, the pre-sieve 5 is in front of the sorting process and the rear sorting action process is long. Is rarely seen.

  Rather than that, the pre-sieve 5 has a large effect of performing pre-selection on the chaff, expands the adaptability of various conditions, and, as already described, can exhibit a unique function of performing pre-selection in front of the chaff sheave 6. There are excellent advantages.

Next, a specific internal configuration of the handling room 15 of the threshing machine 1 will be described for each embodiment with reference to the drawings.
First, as shown in FIGS. 8 and 9, the resistance plate 40 is attached by connecting the base portion to the handling chamber side guide plate 41 and the clamping rod mounting base 42 inside the clamping rod 20 a. It is comprised so that it may be layered and guided over the conveying cereal from the upper side over the starting end part of this. In the case of the embodiment, as shown in FIG. 8, the culm holding and conveying device 20 and the resistance plate 40 are raised to the right side (conveying end side) with respect to the handling cylinder 18 that is pivoted in a substantially horizontal state. It is set as the structure provided in order toward the right along the mouth 21 formed in this. Then, as indicated by the phantom lines in FIG. 9, the resistance plate 40 is integrally lifted upward together with the holding rod 20a when the handle cover 43 is opened and rotated upward as in the known configuration. It has become.

  Next, as shown in FIG. 8 and FIG. 9, the dust feed guide plate 44 is formed in a rectangular plate body in a side view, and the resistance at the right end portion, that is, the portion close to the outlet of the handling chamber 15. In accordance with the shape of the lower edge of the plate 40, a cut upper portion is formed obliquely, and ironing grooves 45, 45 having a width that allows the teeth 19 to pass through are combed in the longitudinal direction in a range from the intermediate portion to the tip portion. The rear portion is configured as a plate-shaped guide portion 44a. As shown in FIG. 9, the dust feeding guide plate 44 is mounted on a front plate 46 and a rear plate 47 constituting the framework of the threshing machine 1 inside the resistance plate 40. A base portion is attached to 48 and the tip end side is extended in the direction of the handle cylinder 18. Then, as shown in the drawing, the dust feed guide plate 44 allows the tip end side to enter the rotation range of the tooth handling teeth 19, 19 and handle the tooth handling teeth 19, 19 to a position where they pass through the ironing grooves 45, 45. The configuration is provided close to the barrel 18 (between the front plate and the middle plate), and the rear plate-shaped safety interior 44a is positioned outside the rotation range of the tooth handling teeth 19 and 19, as shown in FIG. Configured (between the middle plate and the rear plate).

  As shown in FIG. 10, the cutting blade 50 is attached to the attachment frame 48. In this case, the attachment frame 48 is sandwiched and fixed together by sandwiching the attachment frame 48 with the dust feed guide plate 44 facing upward. ing. Then, as can be seen from FIG. 10, the cutting blade 50 is arranged so as to face the rotation range of the tooth handling 19, and is configured to give a receding angle with respect to the rotation direction of the tooth handling 19.

  With this configuration, the cutting blade 50 appropriately cuts the unprocessed material carried around by the tooth handling teeth 19 with a relatively small horsepower consumption and drops it onto the dust feed guide plate 44. Furthermore, the dust feed guide plate No. 44 conveys branch sticky grains and saw dust (many of which grains are mixed) squeezed from the teeth 19 and 19 by the squeezing grooves 45 and 45 without increasing the resistance in the handling chamber 15. It can guide to the barrel 18 side away from the cereal stock, and the number of 4th grain can be greatly reduced. At this time, the cut piece cut by the cutting blade 50 is guided on the guide surface of the dust feed guide plate 44 (the portion of the plate between the ironing groove 45 and the ironing groove 45), and the handling cylinder far from the cereal stock. Guided to the 18th side. Then, as shown in FIG. 10, the mounting frame 48 is brought close to the upper part so as to receive the unprocessed material flowing down through the upper handling chamber side guide plate 41, and further, an inclined safety inner surface 48a is formed. The unprocessed material can be guided to the cutting blade 50.

As shown in FIG. 10, the attachment frame 48 is bent at the lower edge toward the internal cutting edge 50 to form a rotation stop 48b so that the cutting action can be performed accurately.
Next, the partition plate 55 will be described.

  First, as shown in FIGS. 12 and 13, the partition plate 55 is a small grain collection chamber 56 located on the outlet side of the communication port 23 between the handling chamber 15 and the dust disposal chamber 17 and further on the outlet side. Between the upper part of the handling cylinder 18 and the part close to the handling port 21. As shown in the drawing, the partition plate 55 according to this embodiment is composed of upper and lower two plates, an upper partition plate 55a attached to the barrel cover 43 and a lower partition plate 55b attached to the attachment frame 48. Then, the upper partition plate 55a and the lower partition plate 55b are configured to be wrapped at the joint portion.

  With this configuration, the dust discharged from the handling chamber 15 is discharged on the outlet side in the state where the upper portion of the handling cylinder 18 is blocked by the partition plate 55. It is stopped from being sent to the small grain recovery chamber. And most of these dusts are supplied to the dust treatment chamber 17 through the communication port 23. Accordingly, the outlet side grain recovery chamber 56 has an effect that the amount of dust (dust) mixed with grains is reduced and the fourth loss, which is an external loss, can be greatly reduced. Furthermore, since the partition plate 55 is divided into two parts, that is, an upper portion attached to the barrel cover 43 and a lower portion attached using an attachment frame 48 to which the cutting blade 50 and the dust discharge guide plate 44 are attached, Since the lower partition plate 55b is provided close to the axial center of the handling cylinder 18, the partition can be sufficiently performed. Furthermore, since the partition plate 55 is configured by wrapping the joint portion between the lower edge portion of the upper portion 55a and the upper edge portion of the lower portion 55b, there is a feature that the processed material is hardly pinched and is not likely to be clogged. is there.

  Next, as shown in FIGS. 14 and 15, in addition to the cutting blade 50 arranged above the dust feeding guide plate 44 described above, the cutting blade is also formed above the net frame 57 on the back side of the handling chamber 15. Another embodiment in which 58 is arranged will be described.

  First, as shown in FIGS. 14 and 15, the cutting blade 58 is provided by being attached to an attachment frame 60 provided between the front plate 46 and the rear plate 47. Arranged on the upper side, the barrel 18 is configured to cut the threshing carried by the teeth 19 and 19. In this case, the cutting blades 58 are at a position higher than the front cutting blade 50 already described as shown in FIG. 14, and are arranged on different cutting lines as shown in FIG. It is configured to be able to cut the threshing that is carried around 50 different lines.

  If comprised in this way, since the handling chamber 15 was comprised over the mounting frames 48 and 60 which attach the cutting blades 50 and 58 to the front side and the back side, respectively, the rigidity of a frame increased and it became a sturdy structure. There is a characteristic that became. And since the handling chamber 15 provided both the cutting blades 50 and 58 in the high position, the extending range of the receiving net 61 becomes wide, and there exists an attendant effect that the sorting leakage area in the room was expanded.

  And the cutting blades 58 and 50 are increased inside the handling chamber 15 to accurately cut the unprocessed material that the handling cylinder 18 catches around the handling teeth 19 and 19 to improve the degranulation and sorting effect. In addition, there is a feature of reducing the loss of grains outside the machine, and in particular, the generation of abnormal noise in the handling room 15 is much less than in conventional cases even in threshing work under bad conditions for treating wet materials such as rainy weather. There is.
