JP-A-11-266666 JP 2006-67910 A

  In the above configuration, most of the handling chamber is used for the arrangement space of the handling cylinder, and only the narrow space remaining around the handling cylinder is used as a processing space for threshing treatment. When the harvested cereal meal is supplied to the handling room as a threshing product, the processing space may be saturated. When the saturation occurs, the threshing product is sufficiently retained in the processing space. Inconvenience that the threshing product is leaked from the receiving net without performing any threshing processing, or the load required for the threshing processing is increased and the transmission system for the handling cylinder is easily damaged.

  The object of the present invention is a processing capability capable of performing sufficient threshing treatment on a threshing product without causing an increase in load required for the threshing treatment even when a large amount of the threshing treatment product is supplied. An object of the present invention is to provide a barrel structure for a threshing device excellent in the above.

  In order to achieve the above object, in the invention according to claim 1 of the present invention, the threshing process is performed on the harvested cereal meal supplied to the handling room by being rotationally driven about the support shaft. In the barrel structure of the threshing apparatus provided with the barrel to be applied, the rods are arranged in a posture along the support shaft so as to be arranged at predetermined intervals in the circumferential direction of the barrel. A support member provided in front of and behind the support shaft so as to support the rod-shaped member, and a posture projecting outward from the rod-shaped member toward the outside of the handling cylinder in each of the rod-shaped members in the front-rear direction. It comprises a plurality of teeth that are equipped so as to be lined up at a predetermined interval, and the handle cylinder is equipped with a partition member that separates the inner space in the front-rear direction.

  According to this characteristic configuration, the handling cylinder includes a space communicating with the handling chamber in the inside thereof, and allows the threshing processed material to enter the inner space. Therefore, at the time of the rotation operation, while stirring the threshing processed product around it and the threshing processed product that has entered the internal space, the threshing processed product is subjected to a plurality of rod-like members, tooth hitting and swallowing, etc. The threshing process by will be performed.

  In other words, even when a large amount of harvested cereals are supplied to the handling room as a threshing product, the internal space of the handling cylinder can be effectively used as a processing space for the threshing process. It is possible to avoid stagnation of the processed material and saturation of the processing space. As a result, inconvenience that the threshing treatment product leaks from the receiving net without sufficient threshing processing due to the retention of the threshing treatment product or the saturation of the processing space, and the load required for the threshing treatment increases. The occurrence of inconvenience that the transmission system is damaged can be avoided.

  Moreover, by arranging a plurality of rod-shaped members so as to be arranged at a predetermined interval in the circumferential direction of the handling cylinder, it is possible to prevent the winding of the long rod around the rod-shaped member, and the threshing processed product caused by the winding Residence can be avoided. In addition, during the rotation operation of the barrel, a threshing treatment is performed in which not only a plurality of teeth handling teeth but also a plurality of bar-shaped members forming the trunk portion of the barrel are subjected to a threshing treatment by striking or punching the threshing product. Since it comes to function as a member, the threshing performance can be improved.

  In addition, the partitioning member is poor in the threshing process direction such as grains that have been made into single grains by threshing treatment on the front side of the handling cylinder, and unthreshed cereals that have entered the internal space of the handling cylinder in the initial stage of threshing treatment. The flow to the side is suppressed, and the single-grained grains and unthreshed grains are introduced around the barrel along with the rotation of the barrel. It is possible to prevent the occurrence of No. 3 loss due to the cereal meal passing through the inner space of the handling cylinder and being discharged from the lower end portion in the threshing processing direction together with the threshing grain meal.

  Therefore, even when a large amount of threshing products is supplied, sufficient threshing processing can be performed on the threshing products without increasing the load required for the threshing processing, and the third loss. Can prevent the occurrence of damage to the handling cylinder transmission system due to increased load, while improving threshing performance and grain recovery efficiency. As a result, threshing has excellent durability and processing capacity. A handling cylinder structure of the apparatus can be provided.

  In the invention according to claim 2 of the present invention, in the invention according to claim 1, the carp that generates the sorting wind is equipped, and the sorting wind from the carp is made to flow toward the partition member. It is configured as described above.

  According to this characteristic configuration, the threshing processed material dammed up by the partition member is blown toward the periphery of the partition member (periphery of the handle cylinder) by the sorting wind from the tang, and the partition member is rotated along with the rotation of the handle cylinder. Since it flows toward the lower side of the threshing process direction from the periphery of the threshing, it is possible to avoid the possibility that the threshing product is accumulated at a position immediately before the partition member.

  Therefore, it is possible to prevent a reduction in processing capacity due to the accumulation of the threshing product.

  As shown in FIGS. 3 to 5, the threshing device 5 is a handling cylinder 16 that rotates in a handling chamber 14 formed in the upper part thereof with a support shaft 15 that is laid in the conveying direction of the harvested cereal rice cake as a fulcrum. And a lower end of the threshing device 5 in the threshing processing direction, and a receiving net 17 formed in a U shape in front view covering the lower side of the handling cylinder 16 from below. A discharge port 18 is formed at the rear of the receiving net 17, a swing sorting mechanism 19 is provided below the receiving net 17, and a red pepper 20 is provided in front of and below the swing sorting mechanism 19. The first recovery portion 21 is formed below the front side of the front side, the second recovery portion 22 is formed below the rear side of the swing sorting mechanism 19, and the discharge port 23 is formed behind the swing sorting mechanism 19. A top plate 24 that covers the upper side of the trunk 16 from above is provided.

  The handling chamber 14 is partitioned and formed by a receiving net 17 that covers the handling cylinder 16, a top plate 24, and the like, a supply port 25 is formed at a lower part of the front end, and the rear end of the feeder 13 is connected to the supply port 25. The whole of the harvested cereal meal conveyed by the feeder 13 is input and supplied from the supply port 25 as a threshing processed product.

  The handling cylinder 16 has a support shaft 15 that is rotatably mounted on the front wall 26 and the rear wall 27 of the threshing device 5, and is supported by the support shaft 15 with power from the engine 2 transmitted through the carp 20 or the like. The threshing process is applied to the harvested cereals supplied to the handling room 14 by being rotated clockwise as viewed from the front, and the threshing process is performed on the harvested cereals while promoting the singulation of the grains. Transport toward the rear, which is the lower side of the direction.

  The receiving net 17 is a concave receiving net formed in a lattice shape, receives the harvested cereal meal supplied to the handling chamber 14, assists the threshing process of the handling cylinder 16 with respect to the harvested grain meal, and is obtained by the threshing process. Swaying sorting mechanism such as threshing cereal mash while letting the cerealized grains and cereals with branch branch or swarf generated by threshing process leak to the swaying sorting mechanism 19 below Prevent leakage to 19.

  The swing sorting mechanism 19 has a rough sorting grain pan 30, chaff sheave 31, and stroller 32 in that order on the sheave case 29 that is driven to swing back and forth by a cam-type drive mechanism 28. In the lower part of the sheave case 29, a fine sorting grain pan 33 and a grain sheave 34 are arranged in that order from the front side of the sheave case 29. And the sorting processed material leaked from the receiving net 17 in a state where single grains and swarf are mixed is received by the upper grain pan 30, chaff sheave 31 or Strollac 32, and rough sorting processing by sieve sorting is performed. The processed material leaked from the chaff sheave 31 in a state where a single grain or a grain with branch stems is mixed is received by the lower grain pan 33 or the grain sieve 34 and subjected to a fine sorting process by sieving. Applying and sorting the processed products, single grains as No. 1, mixed grains such as grain with branch branch and No. 2 as No. 2, and dust such as Soup as No. 3 To sort.

  The carp 20 is driven by the power from the engine 2 transmitted through the belt-type transmission mechanism 35, and is driven to rotate about the support shaft 20A, thereby generating a sorting wind. By being supplied toward the sorting processed product leaked from the receiving network 17 or the sorting processed product sorted by the swing sorting mechanism 19 through the air passages R1 to R3, A sorting process is performed to blow off swarf or the like having a small specific gravity from the sorted product, and convey it toward the outlet 23 on the lower side in the threshing process direction.

  The first collection unit 21 collects the single-grained grains that have leaked from the grain sieve 34 of the swing sorting mechanism 19 in a state where dust such as straw scraps has been removed by the sorting wind from the Karatsu 20. Then, the recovered first item is conveyed toward the lifting screw 37 (see FIG. 2) that is connected to the right end of the first screw 36 that is disposed in the left-right direction at the bottom.

  The second recovery unit 22 includes a mixture of grains such as branches and cereals that flow down from the rear end of the grain sieve 34 without leaking from the grain sieve 34 of the rocking sorting mechanism 19, and the rocking sorting mechanism 19. A mixture such as cereal grains and sawdust leaking from the Strollac 32 is collected as No. 2 and the No. 2 screw 38 arranged at the bottom side of the collected No. 2 is arranged at the right end. To the second reduction mechanism 39 (see FIG. 2) that is connected in communication.

  The lifting screw 37 lifts the first item conveyed by the first screw 36 and supplies it to the grain tank 40 provided at the upper part of the bagging device 6 (see FIGS. 1 and 2). The second reduction mechanism 39 includes a reprocessing unit (not shown) that performs a threshing process again on the second item conveyed by the second screw 38, and the second item after the threshing process by the reprocessing unit. It is transported and returned to the swing sorting mechanism 19 (see FIG. 2).

  The discharge port 23 is used for removing cereal cereals that do not leak from the receiving net 17 and flow down from the discharge port 18, and swarf sorted and conveyed to the rear of the oscillating and sorting mechanism 19 by a sieving sorting process or a wind sorting process. Release outside the vehicle.

  As shown in FIGS. 3 to 8, the handling cylinder 16 includes a frustoconical scoring portion 41 provided at the front end portion thereof, and a handling processing portion 42 connected to the rear end of the scavenging portion 41. Has been. On the outer peripheral surface of the scraping unit 41, two spiral teeth 43 that scrape and convey the harvested cereal meal supplied from the supply port 25 toward the rear handling processing unit 42 when the handling cylinder 16 is rotated are integrated. Equipped.

  The handling unit 42 includes a first plate (an example of a support member) 44 that is integrally provided at the front portion of the support shaft 15, a second plate (an example of a partition member) 45 that is provided integrally at the front and rear intermediate portions of the support shaft 15, and a support. A third plate (an example of a support member) 46 that is integrally provided at the rear end of the shaft 15, and these plates 44 to 46, in a posture in the front-rear direction along the support shaft 15, at a constant interval in the circumferential direction of the handling cylinder 16. 6 handling cylinder frames (rod-like members) 47 made of round pipe steel supported so as to be spaced apart, and each handling cylinder frame 47 project from the handling cylinder frame 47 toward the outside of the handling cylinder 16. And a plurality of teeth 48 equipped with a predetermined interval in the front-rear direction.

  That is, the handling cylinder 16 is arranged and arranged so that a plurality of handling teeth 48 projecting outward from the handling cylinder 16 are arranged at a predetermined interval in the circumferential direction and the front-rear direction of the handling processing unit 42. The internal space S of the part 42 communicates with the handling chamber 14 so as to allow entry of the threshing product into the internal space S. As a result, during the rotation operation, the surrounding threshing product and While stirring the threshing processed material that has entered the internal space S, the threshing processing is performed on the threshing processed product by striking or punching the handling barrel frame 47 and the tooth handling 48.

  Further, the internal space S of the handling processing unit 42 communicates with the handling chamber 14, so that even when a large amount of harvested cereal meal is supplied to the handling chamber 14 as a threshing processed product, the internal space of the handling processing unit 42. S can be effectively used as a processing space for threshing treatment, and thereby, retention of threshing products in the processing space and saturation of the processing space can be avoided. As a result, the threshing product leaks from the concave 3 without sufficient threshing processing due to the retention of the threshing product or the saturation of the processing space, or the load required for the threshing processing increases and the handling cylinder increases. It is possible to avoid inconveniences such as damage to the transmission system for 16.

  When the handling cylinder 16 is rotated, not only the plurality of tooth handling teeth 48 but also the six handling cylinder frames 47 forming the handling processing section 42 of the handling cylinder 16 are handled handling members that act on the threshing product. Therefore, it is possible to improve threshing performance and threshing efficiency.

  Moreover, by the threshing process on the front side of the handling cylinder 16, many grains become a single grain and leak from the receiving net 17, so that the amount of the threshing processed product decreases in the front and rear intermediate parts, The second plate 45 that separates the internal space S of the handling cylinder 16 from front to back prevents the threshing product in the internal space S of the handling cylinder 16 from flowing to the lower side in the threshing direction, and the threshing process is performed with the rotation of the handling cylinder 16. Since the material is guided to the periphery of the handling cylinder 16 and threshing by hitting or punching the tooth-handling 48 or the like with respect to the threshing processed product, or leakage of the single grain from the receiving net 17 is promoted. Single-grained grains, unthreshed grains, etc. contained in the threshing product pass through the internal space S of the handling cylinder 16 and are discharged together with the threshed grains from the discharge port 18 at the lower end of the threshing processing direction. The occurrence of the third loss due to the above can be prevented.

  Further, when the handling cylinder 16 is rotated, the outside air sucked from the supply port 25 along with the rotation of the helical teeth 43 together with the harvested cereal that is scraped and transported by the action of the scraping portion 41 is surrounded by the circumference of the handling cylinder 16. And flow smoothly into the internal space S of the handling unit 42, thereby preventing the swarf generated from the threshing process from flowing out from the supply port 25 to the feeder 13 and the threshing processed product. The threshing process in the lower direction can be carried more quickly.

  In addition, the outside air sucked from the supply port 25 passes through the inside of the feeder 13 connected to the supply port 25, and the feeder 13 includes the cutting mechanism 11 and the auger 12. Since the supply port 25 communicates with a carry-out port (not shown) for carrying out the recovered cereals formed in the cutting and collecting part, the suction action by the rotation of the helical teeth 43 is caused when the handling cylinder 16 is rotated. In addition, dust such as sawdust generated in the cutting and collecting process in the cutting and collecting unit, along with the outside air, from the carry-out port of the cutting and collecting unit through the internal space of the feeder 13 and the supply port 25, It will flow into the internal space S of the handling processor 42. As a result, it is possible to suppress the accumulation and soaring of sawdust etc. in the harvesting and collecting part, the poor transportation of the harvested cereals due to the deposition and the deterioration of the working environment and visibility due to the soaring, etc. Can be suppressed.

  Each of the plates 44 to 46 has a circular shape centered on the support shaft 15, and a handle cylinder frame 47 is bolted to the outer peripheral side of the plate 44 at an equal distance from the support shaft 15.

  That is, since the six handling cylinder frames 47 are arranged on the outer peripheral side of each of the plates 44 to 46 at regular intervals in the circumferential direction, the cylinder diameter of the handling cylinder 16 is increased. With this, it is possible to prevent the harvested cereal wrapping around the handling cylinder 16.

  Each barrel frame 47 can be reoriented to a normal posture in which the front-rear direction coincides with the front-rear direction of the barrel 16 and an inverted posture in which the front-rear direction is opposite to the front-rear direction of the handle barrel 16, and Bolts are connected to the respective plates 44 to 46 so that the front and rear directions of the adjacent handling cylinder frames 47 are reversed.

  Each handling frame 47 has a plurality of mounting holes 47A and 47B that allow the handling teeth 48 to be mounted in a state where the mounting holes 47A and 47B are arranged at a constant pitch P in the front-rear direction, and from the front end of the handling frame 47 The distance L1 to the center of the hole 47A and the distance L2 from the rear end of the handling frame 47 to the center of the last mounting hole 47A are made different from each other by a half pitch (= 1 / 2P). .

  Each handling cylinder frame 47 is connected and supported by each plate 44 to 46 in a state where the front and rear directions with respect to adjacent ones are reversed, and thereby, the six handling cylinder frames 47 having the same configuration are used. While adopting, it is possible to position the tooth handling 48 mounted on each of these handle barrel frames 47 in a state shifted by a half pitch in the front-rear direction from the tooth handle 48 of the adjacent handle barrel frame 47, As a result, it is possible to reduce the striking interval of the tooth handling 48 against the threshing product without reducing the interval between the adjacent tooth handling teeth 48.

  That is, while reducing the cost by making each handling cylinder frame 47 the same structure, the smaller the gap between adjacent handling teeth 48, the easier it is to invite the cereals in the threshing processed product with respect to the handling teeth 48. While effectively preventing clogging of the threshing product resulting from the entanglement, it is possible to improve the threshing performance by increasing the number of times the tooth handling 48 is struck against the threshing product.

  Further, since each handling cylinder frame 47 is equipped so that the orientation can be changed between the normal posture and the inverted posture, the handling teeth 48 positioned on the upper side in the threshing processing direction, which is relatively easy to wear due to a large amount of the threshing processed material. When wear becomes significant due to long-term use, the direction of each barrel frame 47 is changed, so that the plurality of teeth 48 provided on each barrel frame 47 are relatively easily worn away. The position of the upper teeth 48 and the lower teeth in the threshing direction that are difficult to wear can be changed to a state where they are exchanged at a stroke, whereby the teeth 48 on the lower side in the threshing direction with less wear. Can be effectively used as the tooth handling 48 on the upper side in the threshing process direction with a large amount of processed threshing.

  Of the plurality of mounting holes 47A and 47B, four (two front and rear) mounting holes 47A located at both front and rear ends of each handling cylinder frame 47 are formed to have a smaller diameter than the mounting holes 47B located at the intermediate portion. ing.

  Of each tooth 48, a tooth 48A that is attached using a small-diameter attachment hole 47A is composed of a stepped round bar steel material having a small-diameter portion 48a that is inserted through the attachment hole 47A. A nut is detachably attached to the barrel frame 47 so as to be positioned on a line passing through the center of the support shaft 15 and the center of the barrel frame 47.

  The tooth 48B attached using the intermediate attachment hole 47B is made of a stepless round bar steel material, and the center thereof is located on a line passing through the center of the support shaft 15 and the center of the handling cylinder frame 47. As shown in FIG.

  That is, since each tooth 48A located at both front and rear ends of the handling section 42 is detachable, the teeth 48A are significantly worn by long-term use including changing the direction of the handling frame 47. Can be easily replaced with a new tooth-handling 48A.

  Further, on the lower side of the threshing treatment direction in which the amount of threshing cereal increases, as shown in FIG. 9, if deployed in a state in which the teeth 48 </ b> A located at the rear end of the handling cylinder 16 are thinned, the handling cylinder rear end The interval between the tooth-handling 48A at the portion increases, and the retention of the threshing cereal caused by the catch on the tooth-handling 48A at the rear end of the barrel can be effectively suppressed. Release from the outlet 23 can be facilitated.

  As shown in FIGS. 3 to 5, 10, and 11, the top plate 24 includes a curved portion 24 </ b> A that curves substantially along the rotation locus K of the tooth handling tip, and a semicircular shape that is located at both front and rear ends of the curved portion 24 </ b> A. The vertical wall portion 24B and the straight side edge portions 24C located on the left and right of the curved portion 24A, etc., are closed, and the upper side of the handling cylinder 16 is opened from above. In the open state, the opening / closing swinging operation using a plurality of hinges 24D provided on the left side edge 24C as fulcrums is possible. The right side edge 24C is provided with a plurality of bolts 24E for fixing the top plate 24 in a closed state.

  On the inner surface of the curved portion 24A, there are a plurality of dust feed valves 49 that guide the threshing processed material conveyed to the upper part of the handling chamber 14 toward the lower side in the threshing processing direction in accordance with the rotation operation of the handling cylinder 16. It is fixedly equipped so as to line up in the direction at a predetermined interval. Among the plurality of dust delivery valves 49, the foremost dust delivery valve 49A is formed in an arc shape extending from the front vertical wall portion 24B to the left side edge portion 24C, and the other dust delivery valves 49B are left and right side edge portions. It is formed in an arc shape extending over 24C.

  That is, by providing the top plate 24 with the curved portion 24 </ b> A, the threshing processed material that has been scraped and conveyed to the upper portion of the handling chamber 14 by the plurality of tooth handling 48 and the like as the handling cylinder 16 rotates is applied to the top plate 24. Without violently colliding, it can be smoothly guided toward the receiving net 17 on the lower side of the threshing process direction along the top plate 24 and the dust feed valve 49, and each dust feed valve 49 can be moved to the left side. 49A of each threshing processed material conveyed to the upper part of the handling chamber 14 with rotation of the handling cylinder 16 by having formed in the long circular arc shape over the side edge part 24C or the left and right side edge parts 24C. The guiding action of the threshing can be effectively improved, so that each tooth-handling 48 is not a shape having a conveying action for the threshing processed product, but a shape dedicated to threshing that can suitably hit or plow the threshing processed product. Threshing processed threshing products while forming Towards sense direction downstream side can be favorably transported guide, a result, it is possible to improve the threshing performance and transport performance for threshing treated.

  A steel plate seam member 50 formed so as to have a guide surface connected to the inner surface of the curved portion 24A and the inner edge of the receiving net 17 is detachably bolted to the left and right side edge portions 24C. That is, the seam member 50 that is easily worn due to intense contact with the threshing product by being positioned at the seam between the receiving net 17 and the top plate 24 is configured to be detachable. As in the case of being integrally formed with the joint member 50, it is possible to appropriately treat the wear of the joint member 50 without incurring the trouble and economical disadvantage of replacing the entire top plate 24 by the wear of the joint member 50.

  Incidentally, a small clearance is set between the tip of each tooth-handling 48 and the lower edge of each dust feed valve 49 in order to improve the guidance of the threshing processed product by the dust feed valve 49. In addition, between the tip of each tooth-handling 48 and the inner edge of the receiving net 17, the tip of each tooth-handling 48 and each dust feed valve are used in order to promote the leakage of single grains from the receiving net 17. The clearance larger than the clearance set between the lower edge of 49 is set.

  As shown in FIGS. 3, 4, 6, 12, and 13, between the front wall 26 of the threshing device 5 and the receiving net 17, the harvested cereal meal supplied from the supply port 25 is received, A conveyance assisting member 51 is provided to assist the raking and conveying of the harvested cereal meal by the raking part 41 of the handling cylinder 16. The conveyance auxiliary member 51 is configured by two plates 51 </ b> A that are bolted in a substantially U shape in front view to cover the lower side of the handling cylinder 16 from below, and front and rear of the front wall 26 of the threshing device 5 and the upper portion of the threshing device 5. Bolts are detachably connected to a pair of left and right support frames 52 arranged in the direction. That is, since the conveyance auxiliary member 51 that is easily contacted with the harvested cereal grind and easily wears is configured to be detachable, the conveyance auxiliary member 51 is integrally formed with the receiving net 17 or the left and right support frames 52. The treatment for the abrasion of the conveyance auxiliary member 51 can be appropriately performed without incurring the trouble and the economical disadvantage of replacing the receiving mesh 17 or the left and right support frames 52 together with the conveyance auxiliary member 51 due to the abrasion of the conveyance auxiliary member 51.

  As shown in FIGS. 3, 5, 6, and 14, the receiving net 17 is configured by four receiving net members 53 formed in the same shape, and is detachably bolted to the left and right support frames 52. Yes. Each receiving net member 53 has a base frame 53A in which a plurality of vertical bars 53B made of strip-shaped steel plates are arranged in the front-rear direction in a state of being spaced apart from each other in the circumferential direction of the handling cylinder 16, and are formed in a curved shape in a circular arc shape. A plurality of first horizontal bars 53C made of steel plates are arranged in the left-right direction with a predetermined interval in the front-rear direction as the support shaft direction of the handling cylinder 16, and a plurality of first wires made of piano wire curved in an arc shape are arranged. The two horizontal rails 53D are arranged in the left-right direction with a certain interval in the front-rear direction between the adjacent first horizontal rails 53C, and the mesh has a length in the direction along the circumferential direction of the handling cylinder 16. Is formed in a horizontally long rectangle that is longer than the length in the direction along the front-rear direction.

  That is, the receiving net 17 is configured so that the mesh is a horizontally long rectangle in the rotation direction of the handling cylinder 16, so that the single grain obtained from the threshing process on the harvested corn straw is received by the receiving net 17. Therefore, it is possible to avoid the occurrence of degranulation due to the suppression of leakage of the single-grained grains from the receiving net 17. In addition, since the receiving net members 53 are formed in the same shape, the productivity and assembly of the receiving net 17 can be improved.

  As shown in FIGS. 3 and 15, the rough sorting chaff sheave 31 is composed of a single sorting plate 54, and is bolted to the sheave case 29 in a back-up and inclined posture located on the lower side in the sorting direction. ing.

  On the front side of the sorting plate 54 (1/3 of the entire sorting plate 54), a plurality of leakage holes 54A formed in a rectangular shape in plan view are arranged between the leakage holes 54A in the front row. It is formed in a zigzag pattern in which the lower holes 54A are located. On the rear side of the sorting plate 54 (2/3 of the sorting plate 54 as a whole), a plurality of leakage holes 54B and 54C formed in a rectangular shape in plan view having sorting pieces 54a and 54b are leaked in the front row. Between the holes 54B and 54C, the rear row leakage holes 54B and 54C are arranged in a staggered manner.

  Among the sorting pieces 54a and 54b, the sorting piece 54a located on the left and right center side of the sorting plate 54 is formed so as to be narrower and closer to the upper side in the sorting direction. The sorting pieces 54b located at the left and right ends of the sorting plate 54 are rectangular in shape shorter than the sorting pieces 54a on the left and right center sides, and are formed so as to be positioned higher on the lower side in the sorting direction.

  That is, since the chaff sheave 31 for rough sorting is constituted by a single sorting plate 54, for example, the chaff sheave 31 is configured by arranging a large number of chaff flips made of strip steel plates so as to be spaced apart in the front-rear direction. Compared with the case where it does, the simplification of a structure and the reduction of cost can be aimed at.

  And the front part of the chaff sheave 31 is formed by forming the leakage hole 54A not provided with the sorting pieces 54a and 54b on the front part side of the chaff sheave 31 to which the processed product with a high content of single grains is supplied. The number of single grains that leak from the side to the lower grain pan 33 and the grain sieve 34 increases, and as a result, the recovery rate of the single grains can be increased.

  Further, the leakage holes 54B and 54C provided with the sorting pieces 54a and 54b are formed in a staggered manner in the front, rear, left and right sides on the rear side of the chaff sheave 31, so that the sorting processed product on the chaff sheave 31 is not separated in the sieve sorting process. It will be evenly distributed in the left-right direction, so that the leakage of single grains from the respective leakage holes 54B, 54C can be promoted. In addition, since the chaff sheave 31 is installed in a rearwardly inclined posture, the chaff sheave 31 moves the sorting processing product to the upper side in the sorting processing direction in the sieve sorting process as compared with the case where the chaff sheave 31 is installed in the horizontal posture. This increases the force that pushes out the product, and this suppresses the transport of the sorted product to the lower side of the sorting direction, and the vertical movement of the sorted product becomes intense, making the specific gravity difference sorting of the sorted product more effective. Therefore, it is possible to effectively prevent the occurrence of the third loss in which the leakage of the grains having a large specific gravity from the respective leakage holes 54B and 54C is promoted and the single grains are discharged from the outlet 23 to the outside of the vehicle. As a result, the grain recovery efficiency can be improved.

  Further, the sorting pieces 54b at the left and right ends of the chaff sheave 31 are formed to be shorter than the sorting pieces 54a at the center of the left and right sides, so that the grains from the leakage holes 54C at the left and right ends where the sorting processed product in the chaff sheave 31 is easy to accumulate. Leakage of grains and the like can be promoted, and as a result, it is possible to avoid a reduction in sorting efficiency due to the accumulation of sorting processed products at the left and right ends of the chaff sheave 31.

  Incidentally, the ratio of the leakage holes 54A that are not provided with the sorting pieces 54a and 54b formed in the chaff sheave 31 and the leakage holes 54B and 54C that are provided with the sorting pieces 54a and 54b depends on the types of grains to be selected. Various changes can be made accordingly.

  In addition, a plurality of leakage holes 54C formed in a rectangular shape in plan view so as to have a short rectangular selection piece 54b on the front side of the selection plate 54 are arranged between the front row leakage holes 54C. You may make it form in a zigzag form where the leakage hole 54C is located.

  As shown in FIG. 3, of the selected air from the tang 20, the selected air that passes through the upper air passage R <b> 1 passes through the air passage R <b> 4 formed in the sheave case 29 toward the second plate 45 of the handling cylinder 16. To flow. Thereby, the threshing processed product that is prevented from flowing toward the lower side in the threshing processing direction by the second plate 45 can be wind-winded toward the periphery of the handling cylinder 16, and as a result, the threshing processed product is transferred to the second plate 45. It is possible to avoid the possibility that the threshing process will be hindered by depositing at a location immediately before.

  As shown in FIGS. 3 and 6, the handle 16 is configured such that the handle teeth 48 </ b> A located at the rear end thereof are positioned rearward of the rear end of the receiving net 17 and face the discharge port 18. That is, since the receiving net 17 is not present at the rear end of the handling cylinder 16, a relatively large space is formed around the receiving net 17. Even if the cereals are entangled, the threshing cereals come out of the tips of the teeth 48A due to the centrifugal force associated with the rotation of the case 16, and as a result, the teeth are treated at the rear end of the handle 16. It is possible to effectively suppress the retention of the shed cereal meal due to the catch on 48A, and it is possible to promote the release of the shed cereal meal from the discharge port 18.

  When the handling cylinder 16 is rotated, not only the plurality of tooth handling teeth 48 but also the six handling cylinder frames 47 forming the handling processing section 42 of the handling cylinder 16 are handled handling members that act on the threshing product. Therefore, it is possible to improve threshing performance and threshing efficiency.

  Moreover, by the threshing process on the front side of the handling cylinder 16, many grains become a single grain and leak from the receiving net 17, so that the amount of the threshing processed product decreases in the front and rear intermediate parts, The second plate 45 that separates the internal space S of the handling cylinder 16 from front to back prevents the threshing product in the internal space S of the handling cylinder 16 from flowing to the lower side in the threshing direction, and the threshing process is performed with the rotation of the handling cylinder 16. Since the material is guided to the periphery of the handling cylinder 16 and threshing by hitting or punching the tooth-handling 48 or the like with respect to the threshing processed product, or leakage of the single grain from the receiving net 17 is promoted. Single-grained grains, unthreshed grains, etc. contained in the threshing product pass through the internal space S of the handling cylinder 16 and are discharged together with the threshed grains from the discharge port 18 at the lower end of the threshing processing direction. The occurrence of the third loss due to the above can be prevented.

  Further, when the handling cylinder 16 is rotated, the outside air sucked from the supply port 25 along with the rotation of the helical teeth 43 together with the harvested cereal that is scraped and transported by the action of the scraping portion 41 is surrounded by the circumference of the handling cylinder 16. And flow smoothly into the internal space S of the handling unit 42, thereby preventing the swarf generated from the threshing process from flowing out from the supply port 25 to the feeder 13 and the threshing processed product. The threshing process in the lower direction can be carried more quickly.

  In addition, the outside air sucked from the supply port 25 passes through the inside of the feeder 13 connected to the supply port 25, and the feeder 13 includes the cutting mechanism 11 and the auger 12. Since the supply port 25 communicates with a carry-out port (not shown) for carrying out the recovered cereals formed in the cutting and collecting part, the suction action by the rotation of the helical teeth 43 is caused when the handling cylinder 16 is rotated. In addition, dust such as sawdust generated in the cutting and collecting process in the cutting and collecting unit, along with the outside air, from the carry-out port of the cutting and collecting unit through the internal space of the feeder 13 and the supply port 25, It will flow into the internal space S of the handling processor 42. As a result, it is possible to suppress the accumulation and soaring of sawdust etc. in the harvesting and collecting part, the poor transportation of the harvested cereals due to the deposition and the deterioration of the working environment and visibility due to the soaring, etc. Can be suppressed.

  Each of the plates 44 to 46 has a circular shape centered on the support shaft 15, and a handle cylinder frame 47 is bolted to the outer peripheral side of the plate 44 at an equal distance from the support shaft 15.

  That is, since the six handling cylinder frames 47 are arranged on the outer peripheral side of each of the plates 44 to 46 at regular intervals in the circumferential direction, the cylinder diameter of the handling cylinder 16 is increased. With this, it is possible to prevent the harvested cereal wrapping around the handling cylinder 16.

  Each barrel frame 47 can be reoriented to a normal posture in which the front-rear direction coincides with the front-rear direction of the barrel 16 and an inverted posture in which the front-rear direction is opposite to the front-rear direction of the handle barrel 16, and Bolts are connected to the respective plates 44 to 46 so that the front and rear directions of the adjacent handling cylinder frames 47 are reversed.

  Each handling frame 47 has a plurality of mounting holes 47A and 47B that allow the handling teeth 48 to be mounted in a state where the mounting holes 47A and 47B are arranged at a constant pitch P in the front-rear direction, and from the front end of the handling frame 47 The distance L1 to the center of the hole 47A and the distance L2 from the rear end of the handling frame 47 to the center of the last mounting hole 47A are made different from each other by a half pitch (= 1 / 2P). .

  Each handling cylinder frame 47 is connected and supported by each plate 44 to 46 in a state where the front and rear directions with respect to adjacent ones are reversed, and thereby, the six handling cylinder frames 47 having the same configuration are used. While adopting, it is possible to position the tooth handling 48 mounted on each of these handle barrel frames 47 in a state shifted by a half pitch in the front-rear direction from the tooth handle 48 of the adjacent handle barrel frame 47, As a result, it is possible to reduce the striking interval of the tooth handling 48 against the threshing product without reducing the interval between the adjacent tooth handling teeth 48.

While trying to reduce the cost by making each handling cylinder frame 47 the same configuration, the smaller the interval between adjacent handling teeth 48, the easier it is to invite the culm in the threshing processed product to the handling teeth 48. It is possible to improve the threshing performance by increasing the number of times the tooth handling 48 is struck against the threshing product while effectively preventing the clogging of the resulting threshing product.

  Further, since each handling cylinder frame 47 is equipped so that the orientation can be changed between the normal posture and the inverted posture, the handling teeth 48 positioned on the upper side in the threshing processing direction, which is relatively easy to wear due to a large amount of the threshing processed material. When wear becomes significant due to long-term use, the direction of each barrel frame 47 is changed, so that the plurality of teeth 48 provided on each barrel frame 47 are relatively easily worn away. The position of the upper teeth 48 and the lower teeth in the threshing direction that are difficult to wear can be changed to a state where they are exchanged at a stroke, whereby the teeth 48 on the lower side in the threshing direction with less wear. Can be effectively used as the tooth handling 48 on the upper side in the threshing process direction with a large amount of processed threshing.

  Of the plurality of mounting holes 47A and 47B, four (two front and rear) mounting holes 47A located at both front and rear ends of each handling cylinder frame 47 are formed to have a smaller diameter than the mounting holes 47B located at the intermediate portion. ing.

  Of each tooth 48, a tooth 48A that is attached using a small-diameter attachment hole 47A is composed of a stepped round bar steel material having a small-diameter portion 48a that is inserted through the attachment hole 47A. A nut is detachably attached to the barrel frame 47 so as to be positioned on a line passing through the center of the support shaft 15 and the center of the barrel frame 47.

  The tooth 48B attached using the intermediate attachment hole 47B is made of a stepless round bar steel material, and the center thereof is located on a line passing through the center of the support shaft 15 and the center of the handling cylinder frame 47. As shown in FIG.

  That is, since each tooth 48A located at both front and rear ends of the handling section 42 is detachable, the teeth 48A are significantly worn by long-term use including changing the direction of the handling frame 47. Can be easily replaced with a new tooth-handling 48A.

  Further, on the lower side of the threshing treatment direction in which the amount of threshing cereal increases, as shown in FIG. 9, if deployed in a state in which the teeth 48 </ b> A located at the rear end of the handling cylinder 16 are thinned, the handling cylinder rear end The interval between the tooth-handling 48A at the portion increases, and the retention of the threshing cereal caused by the catch on the tooth-handling 48A at the rear end of the barrel can be effectively suppressed. Release from the outlet 23 can be facilitated.

  As shown in FIGS. 3 to 5, 10, and 11, the top plate 24 includes a curved portion 24 </ b> A that curves substantially along the rotation locus K of the tooth handling tip, and a semicircular shape that is located at both front and rear ends of the curved portion 24 </ b> A. The vertical wall portion 24B and the straight side edge portions 24C located on the left and right of the curved portion 24A, etc., are closed, and the upper side of the handling cylinder 16 is opened from above. In the open state, the opening / closing swinging operation using a plurality of hinges 24D provided on the left side edge 24C as fulcrums is possible. The right side edge 24C is provided with a plurality of bolts 24E for fixing the top plate 24 in a closed state.

  On the inner surface of the curved portion 24A, there are a plurality of dust feed valves 49 that guide the threshing processed material conveyed to the upper part of the handling chamber 14 toward the lower side in the threshing processing direction in accordance with the rotation operation of the handling cylinder 16. It is fixedly equipped so as to line up in the direction at a predetermined interval. Among the plurality of dust delivery valves 49, the foremost dust delivery valve 49A is formed in an arc shape extending from the front vertical wall portion 24B to the left side edge portion 24C, and the other dust delivery valves 49B are left and right side edge portions. It is formed in an arc shape extending over 24C.

  That is, by providing the top plate 24 with the curved portion 24 </ b> A, the threshing processed material that has been scraped and conveyed to the upper portion of the handling chamber 14 by the plurality of tooth handling 48 and the like as the handling cylinder 16 rotates is applied to the top plate 24. Without violently colliding, it can be smoothly guided toward the receiving net 17 on the lower side of the threshing process direction along the top plate 24 and the dust feed valve 49, and each dust feed valve 49 can be moved to the left side. 49A of each threshing processed material conveyed to the upper part of the handling chamber 14 with rotation of the handling cylinder 16 by having formed in the long circular arc shape over the side edge part 24C or the left and right side edge parts 24C. The guiding action of the threshing can be effectively improved, so that each tooth-handling 48 is not a shape having a conveying action for the threshing processed product, but a shape dedicated to threshing that can suitably hit or plow the threshing processed product. Threshing processed threshing products while forming Towards sense direction downstream side can be favorably transported guide, a result, I am possible to improve the threshing performance and transport performance for threshing treated.

A steel plate seam member 50 formed so as to have a guide surface connected to the inner surface of the curved portion 24A and the inner edge of the receiving net 17 is detachably bolted to the left and right side edge portions 24C. That Ri受 network 17 and by contact with the threshing treated by located joint between the top plate 24 is detachably attached to the easy joint member 50 wears becomes violent, the top plate 24 and the joint member 50 As in the case of being integrally formed with the joint member 50, it is possible to appropriately treat the wear of the joint member 50 without incurring the trouble and economical disadvantage of replacing the entire top plate 24 by the wear of the joint member 50.

  Incidentally, a small clearance is set between the tip of each tooth-handling 48 and the lower edge of each dust feed valve 49 in order to improve the guidance of the threshing processed product by the dust feed valve 49. In addition, between the tip of each tooth-handling 48 and the inner edge of the receiving net 17, the tip of each tooth-handling 48 and each dust feed valve are used in order to promote the leakage of single grains from the receiving net 17. The clearance larger than the clearance set between the lower edge of 49 is set.

  As shown in FIGS. 3, 4, 6, 12, and 13, between the front wall 26 of the threshing device 5 and the receiving net 17, the harvested cereal meal supplied from the supply port 25 is received, A conveyance assisting member 51 is provided to assist the raking and conveying of the harvested cereal meal by the raking part 41 of the handling cylinder 16. The conveyance auxiliary member 51 is configured by two plates 51 </ b> A that are bolted in a substantially U shape in front view to cover the lower side of the handling cylinder 16 from below, and front and rear of the front wall 26 of the threshing device 5 and the upper portion of the threshing device 5. Bolts are detachably connected to a pair of left and right support frames 52 arranged in the direction. That is, since the conveyance auxiliary member 51 that is easily contacted with the harvested cereal grind and easily wears is configured to be detachable, the conveyance auxiliary member 51 is integrally formed with the receiving net 17 or the left and right support frames 52. The treatment for the abrasion of the conveyance auxiliary member 51 can be appropriately performed without incurring the trouble and the economical disadvantage of replacing the receiving mesh 17 or the left and right support frames 52 together with the conveyance auxiliary member 51 due to the abrasion of the conveyance auxiliary member 51.

  As shown in FIGS. 3, 5, 6, and 14, the receiving net 17 is configured by four receiving net members 53 formed in the same shape, and is detachably bolted to the left and right support frames 52. Yes. Each receiving net member 53 has a base frame 53A in which a plurality of vertical bars 53B made of strip-shaped steel plates are arranged in the front-rear direction in a state of being spaced apart from each other in the circumferential direction of the handling cylinder 16, and are formed in a curved shape in a circular arc shape. A plurality of first horizontal bars 53C made of steel plates are arranged in the left-right direction with a predetermined interval in the front-rear direction as the support shaft direction of the handling cylinder 16, and a plurality of first wires made of piano wire curved in an arc shape are arranged. The two horizontal rails 53D are arranged in the left-right direction with a certain interval in the front-rear direction between the adjacent first horizontal rails 53C, and the mesh has a length in the direction along the circumferential direction of the handling cylinder 16. Is formed in a horizontally long rectangle that is longer than the length in the direction along the front-rear direction.

  That is, the receiving net 17 is configured so that the mesh is a horizontally long rectangle in the rotation direction of the handling cylinder 16, so that the single grain obtained from the threshing process on the harvested corn straw is received by the receiving net 17. Therefore, it is possible to avoid the occurrence of degranulation due to the suppression of leakage of the single-grained grains from the receiving net 17. In addition, since the receiving net members 53 are formed in the same shape, the productivity and assembly of the receiving net 17 can be improved.

  As shown in FIGS. 3 and 15, the rough sorting chaff sheave 31 is composed of a single sorting plate 54, and is bolted to the sheave case 29 in a back-up and inclined posture located on the lower side in the sorting direction. ing.

  On the front side of the sorting plate 54 (1/3 of the entire sorting plate 54), a plurality of leakage holes 54A formed in a rectangular shape in plan view are arranged between the leakage holes 54A in the front row. It is formed in a zigzag pattern in which the lower holes 54A are located. On the rear side of the sorting plate 54 (2/3 of the sorting plate 54 as a whole), a plurality of leakage holes 54B and 54C formed in a rectangular shape in plan view having sorting pieces 54a and 54b are leaked in the front row. Between the holes 54B and 54C, the rear row leakage holes 54B and 54C are arranged in a staggered manner.

Each sorting pieces 54a, among 54b, sorting piece 54a located on the left and right center side of the sorting plate 54 is formed embossed scaly located above a narrow width as selected by the direction downstream side. The sorting pieces 54b located at the left and right ends of the sorting plate 54 are rectangular in shape shorter than the sorting pieces 54a on the left and right center sides, and are formed so as to be positioned higher on the lower side in the sorting direction.

  That is, since the chaff sheave 31 for rough sorting is constituted by a single sorting plate 54, for example, the chaff sheave 31 is configured by arranging a large number of chaff flips made of strip steel plates so as to be spaced apart in the front-rear direction. Compared with the case where it does, the simplification of a structure and the reduction of cost can be aimed at.

  And the front part of the chaff sheave 31 is formed by forming the leakage hole 54A not provided with the sorting pieces 54a and 54b on the front part side of the chaff sheave 31 to which the processed product with a high content of single grains is supplied. The number of single grains that leak from the side to the lower grain pan 33 and the grain sieve 34 increases, and as a result, the recovery rate of the single grains can be increased.

  Further, the leakage holes 54B and 54C provided with the sorting pieces 54a and 54b are formed in a staggered manner in the front, rear, left and right sides on the rear side of the chaff sheave 31, so that the sorting processed product on the chaff sheave 31 is not separated in the sieve sorting process. It will be evenly distributed in the left-right direction, so that the leakage of single grains from the respective leakage holes 54B, 54C can be promoted. In addition, since the chaff sheave 31 is installed in a rearwardly inclined posture, the chaff sheave 31 moves the sorting processing product to the upper side in the sorting processing direction in the sieve sorting process as compared with the case where the chaff sheave 31 is installed in the horizontal posture. This increases the force that pushes out the product, and this suppresses the transport of the sorted product to the lower side of the sorting direction, and the vertical movement of the sorted product becomes intense, making the specific gravity difference sorting of the sorted product more effective. Therefore, it is possible to effectively prevent the occurrence of the third loss in which the leakage of the grains having a large specific gravity from the respective leakage holes 54B and 54C is promoted and the single grains are discharged from the outlet 23 to the outside of the vehicle. As a result, the grain recovery efficiency can be improved.

  Further, the sorting pieces 54b at the left and right ends of the chaff sheave 31 are formed to be shorter than the sorting pieces 54a at the center of the left and right sides, so that the grains from the leakage holes 54C at the left and right ends where the sorting processed product in the chaff sheave 31 is easy to accumulate. Leakage of grains and the like can be promoted, and as a result, it is possible to avoid a reduction in sorting efficiency due to the accumulation of sorting processed products at the left and right ends of the chaff sheave 31.

  Incidentally, the ratio of the leakage holes 54A that are not provided with the sorting pieces 54a and 54b formed in the chaff sheave 31 and the leakage holes 54B and 54C that are provided with the sorting pieces 54a and 54b depends on the types of grains to be selected. Various changes can be made accordingly.

  In addition, a plurality of leakage holes 54C formed in a rectangular shape in plan view so as to have a short rectangular selection piece 54b on the front side of the selection plate 54 are arranged between the front row leakage holes 54C. You may make it form in a zigzag form where the leakage hole 54C is located.

  As shown in FIG. 3, of the selected air from the tang 20, the selected air that passes through the upper air passage R <b> 1 passes through the air passage R <b> 4 formed in the sheave case 29 toward the second plate 45 of the handling cylinder 16. To flow. Thereby, the threshing processed product that is prevented from flowing toward the lower side in the threshing processing direction by the second plate 45 can be wind-winded toward the periphery of the handling cylinder 16, and as a result, the threshing processed product is transferred to the second plate 45. It is possible to avoid the possibility that the threshing process will be hindered by depositing at a location immediately before.

  As shown in FIGS. 3 and 6, the handle 16 is configured such that the handle teeth 48 </ b> A located at the rear end thereof are positioned rearward of the rear end of the receiving net 17 and face the discharge port 18. That is, since the receiving net 17 is not present at the rear end of the handling cylinder 16, a relatively large space is formed around the receiving net 17. Even if the cereals are entangled, the threshing cereals come out of the tips of the teeth 48A due to the centrifugal force associated with the rotation of the case 16, and as a result, the teeth are treated at the rear end of the handle 16. It is possible to effectively suppress the retention of the shed cereal meal due to the catch on 48A, and it is possible to promote the release of the shed cereal meal from the discharge port 18.
