Description

  The present invention relates to a harvesting and harvesting machine, and more particularly to a structure of a harvesting section of a general-purpose combiner.

  Conventionally, there is a general-purpose combine as one form of a harvesting harvester, and the harvesting part of the general-purpose combiner has a scraping unit that scrapes the harvested cereal toward the center, and a cereal that has been scraped by the scoring unit. It is equipped with a transport unit that takes in from the slot and transports it backwards. Then, the scraping unit feeds the harvested cereals to the substantially central portion by a scraping auger laid horizontally in the platform, and the conveying unit (feeder house) is arranged close to the substantially central portion of the scraping auger. The harvested cereal meal is carried into the carry-in entrance part and is carried out from the carry-out part to the threshing part.

  The stirrer auger has a left spiral screw blade that conveys the harvested cereal rice cake from the left side to the approximate central portion on the outer peripheral surface of the drum with the axis line directed in the left-right direction, and the near-central portion of the harvested cereal rice cake from the right side And a right spiral screw blade is provided. In this way, the cereals are carried into the carry-in entrance of the feeder house while being gathered from the left and right by the take-up auger. For example, Patent Literature 1 discloses a harvesting and harvesting machine that leveles the amount of cereals conveyed by a scraping auger.

No. 08-001622

  However, the rotation speed of the above-mentioned scraping auger is constant with respect to the vehicle speed. Further, the carry-in portion of the feeder house is provided at a position (left side as viewed from the driver) that is offset from the center of the take-up auger. If the conveying space for the cereals between the right end of the feeder entrance and the right end of the take-up auger is long, the amount of cereals in that space increases. On the other hand, since the conveyance space of the corn straw between the left end part of the carry-in entrance part of a feeder house and the left end part of the take-in auger is narrow, the stagnation of the corn straw tends to occur in that space.

  The present invention has been made to solve the above-mentioned problem, and a combine that prevents stagnation of cereals and improves harvesting and conveying performance between a take-in auger in a platform and a carry-in port of a feeder house. The purpose is to provide.

  The invention according to claim 1 includes: a scraping portion that scrapes the harvested cereal toward the center portion; and a transport portion that takes in the cereal scraped by the scraping portion from the inlet and conveys it backward. Equipped with a cutting auger that is equipped with a cutting auger that is approximately the same width as the entire cutting width, the cutting auger is placed just before the inlet of the transport unit and is open to the inlet An intermediate auger forming body having substantially the same width as the width, a one-side auger forming body that scrapes the cereals into the intake of the transport unit from one side through the intermediate auger forming body, and an intermediate auger forming body from the other side The other side auger forming body that scrapes the cereals into the intake of the transport unit via the coaxial arrangement is formed, and the intermediate auger forming body has a relatively short width on one side The auger forming body is larger than the auger forming body, and the same side auger forming body has a larger scoring force than the other auger forming body. It is a reaper harvester and butterflies.

  The invention according to claim 2 is the harvesting and harvesting machine according to claim 1, wherein the auger forming body has a different number of revolutions as a scratching force.

  According to a third aspect of the present invention, the first transmission portion and the second transmission portion are provided in the take-up auger, and the intermediate auger formation body is interlocked with the one-side auger formation body via the first transmission portion. 3. The harvesting and harvesting machine according to claim 2, wherein the harvesting and harvesting machine is interlocked and connected to the other auger forming body via the second transmission portion.

  According to a fourth aspect of the present invention, the first auger drive first and second electric motors and the first and second transmission units are provided in the auger auger, and the intermediate auger is provided by the first electric motor via the first transmission unit. The revolving speed of the forming body and the one-side auger forming body is variable, and the second electric motor is used to change the revolving speed of the intermediate auger forming body and the other-side auger forming body via the second transmission unit. The harvesting and harvesting machine according to claim 1, characterized in that:

  According to a fifth aspect of the present invention, the one side auger forming body and the other side auger forming body take in driving force from different transmission systems, respectively, and an intermediate auger formation is formed on either one of the auger forming bodies via the transmission unit. 2. The harvesting and harvesting machine according to claim 1, wherein the bodies are linked and connected.

  (1) In the present invention described in claim 1, a scraping portion that scrapes the harvested cereal toward the center, and a transport that takes the cereal that has been scraped by the scraping portion from the inlet and conveys it backward. In a harvesting and harvesting machine equipped with a scraping auger with the same width as the full cutting width in the scraping section, the scraping auger is arranged immediately before the intake port of the transport section An intermediate auger formation body having substantially the same width as the opening width of the mouth, a one-side auger formation body that scrapes the cereals into the intake of the transport unit from one side through the intermediate auger formation body, and an intermediate from the other side The other side auger forming body that scrapes the cereals into the inlet of the transport section via the auger forming body is coaxially arranged and the intermediate auger forming body has a relatively short driving force. The one side auger forming body is larger than the scratching force, and the same side auger forming body has a larger scratching force than the other side auger forming body. There.

  For example, if the length between the right end of the intake port of the transport section (feeder house) and the right end of the take-up auger (the transport space on the other auger forming body side) is long, the amount of cereals transported there However, the intermediate auger forming body arranged just before the intake port of the transport section has a larger scuffing force than that of the relatively short one-side auger forming body to form the same auger. By making the scraping force of the body larger than that of the other auger forming body, it is possible to reduce the stagnation of the cereals on the other auger forming body side and to improve the conveyance performance Can do. Moreover, since the scrambling force of the intermediate auger forming body is greater than the scoring force of the one side auger forming body, the stagnation of cereals on the one side auger forming body side can be reduced and the conveyance performance is improved. be able to.

  Furthermore, the cereal conveyance space between the left end of the feeder house intake and the left end of the take-up auger (one-side auger forming body-side conveyance space) is shorter than the other-side auger forming body-side conveyance space. The width and the amount of cereals that are transported are small, so the take-in ability at the confluence point in front of the take-in port of the transport unit is deteriorated. Since it is greater than the scorching force of the body, the conveyance performance at the junction can be improved.

  (2) In the present invention according to claim 2, since the number of rotations of each auger forming body is made different as the force for taking in, it is possible to make the force to be turned in accordance with the location of the biting auger, It is possible to reduce the stagnation of cereals at the place where the auger is located.

  (3) In the present invention described in claim 3, the first speed change portion and the second speed change portion are provided in the take-in auger, and the intermediate auger formation body is interlocked with the one-side auger formation body via the first speed change portion. In addition to being connected, the auger forming body is interlocked and connected via the second speed change portion, so that each auger forming body can be rotated at different rotational speeds, and a different and different scratching force can be generated. Can be made.

  (4) In the present invention according to claim 4, the first and second electric motors for driving the auger and the first and second transmission parts are provided in the scraping auger, and the first electric motor causes the first transmission part to pass through the first transmission part. The variable rotation speeds of the intermediate auger formation body and the one-side auger formation body are variable, and the second electric motor is used to change the rotation speed of the intermediate auger formation body and the other-side auger formation body via the second transmission. It is variable.

  In this way, each auger forming body can be individually rotated at a different number of rotations, and the conveyance amount of the cereals laterally fed by each auger forming body can be adjusted. In addition, the conveyance efficiency can be ensured satisfactorily by appropriately changing the number of rotations of each auger forming body according to the amount of cereals to be conveyed.

  (5) In the present invention according to claim 5, the one-side auger forming body and the other-side auger forming body take in the driving force from different transmission systems, respectively, and either one of these auger forming bodies via the transmission unit. The intermediate auger forming body is linked and connected. For example, the other side auger forming body is driven by transmitting power from the engine, and the intermediate auger is driven via the transmission unit, while the one side auger forming body is driven by transmitting the power of the electric motor. You may make it do.

  In this way, each auger forming body can be driven with different power with a simple structure. For example, by setting the magnitude relationship of the scraping force as follows: scratching force of the intermediate auger forming body> scratching force of the one side auger forming body> scratching force of the other side auger forming body, It is possible to improve the transportability of the culm of the near intermediate auger forming body and improve the transportability of the culm in the other auger forming bodies.

  The combine in the present embodiment has, as a basic structure, a scraping unit that scrapes the harvested cereal toward the center, and a transport that takes the cereal scraped by the scraping unit from the intake and conveys it backward. And a scraping auger having substantially the same width as the full cutting width.

  And, the stirrer auger forms the one side auger forming body that scrapes the cereals into the intake of the transport unit from one side, and the other side auger formation that scrapes the cereals into the intake of the transport unit from the other side The one side auger forming body having a relatively short width is formed so as to be coaxial with the body, and the number of rotations of the one side auger forming body is larger than the number of rotations of the other side auger forming body.

  In the configuration as described above, the gist of the present invention is that the take-in auger 13 is moved from one side (left side in the present embodiment) to the take-in port of the transfer unit 4 in the take-up unit 16 provided in the cutting unit 2. The one-side auger forming body 91 that scrapes the cereal into 93 and the other-side auger forming body 92 that scrapes the cereal into the intake 93 of the transport unit 4 from the other side (right side in the present embodiment) are coaxial. The intermediate auger forming body 99 has a scraping force (i.e., the ability to allow the culm to be taken into the intake port 93 disposed immediately behind) of the one-side auger forming body 91. One side auger formation, greater than the pick-up force (that is, the ability to move the harvested cereals to the right side to the right side 93 so that the cereals can be taken into the right side 93) The picking force of the body 91 is taken as the picking force of the other auger forming member 92 (ie, the harvested cereal is taken in) And lateral conveyance to the left side to 93 is that the same cereal stalk is no larger than the ability) to ensure incorporated into the inlet 93. Hereinafter, the scraping auger 13 and the FH conveyor 14 will be described in detail.

  The FH conveyor 14 has a drum 20 pivotally supported by a driven side shaft extending in the left-right direction at the front portion in the feeder house 60, and a driving side shaft 22 extending in the left-right direction at the rear portion in the feeder house 60. A pair of left and right feeder chains 24, 24 are wound endlessly between the drum 20 and the drive side shaft 22 via a sprocket, and a large number of conveying bodies 83 are interposed between the feeder chains 24, 24. Are placed horizontally with a gap in the front-rear direction. And the conveyance path | route which conveys the grain straw between the bottom face of the feeder house 60 and the lower conveyance part of the FH conveyor 14 is formed. In this way, the cereals harvested through the transport path are transported from the harvesting unit 2 to the threshing unit 5.

  As shown in FIGS. 3 and 4, the take-up auger 13 is formed by extending in the left-right direction (the left-right width direction of the machine body), the one-side auger forming body 91, the other-side auger forming body 92, and the intermediate auger forming body 99. It is divided into three parts. That is, the take-up auger 13 is disposed immediately before the intake port of the transport unit 4 and has an intermediate auger forming body 99 having substantially the same width as the opening width of the intake port 93 and one side (in this embodiment). One side auger forming body 91 that scrapes the cereal into the intake port 93 of the feeder house 60 from the left side, and the cereal to the intake port 93 of the feeder house 60 from the other side (right side in this embodiment). The other auger forming body 92 to be scraped is formed coaxially. The one-side auger forming body 91 and the other-side auger forming body 92 are respectively provided with spiral blade bodies 54a, 54b (on the outer periphery of cylindrical forming body bodies 71a, 71b having substantially the same diameter extending in the left-right direction. A spiral conveyor) is attached and formed. The intermediate auger forming body 99 includes a cylindrical forming body main body 71c that is disposed between the one-side auger forming body 91 and the other-side auger forming body 92 and extends in the left-right direction. The main body 71c is formed in a cylindrical shape having substantially the same diameter as the formed body main bodies 71a and 71b.

  The right edge portion of the one-side auger forming body 91 and the left edge portion of the intermediate auger forming body 99 are joined to each other so as to be rotatable around the axis, thereby forming a first joining portion 94a. The right edge portion of the intermediate auger forming body 99 and the left edge portion of the other auger forming body 92 are joined to each other so as to be rotatable about the axis, thereby forming a second joining portion 94b. The first joint portion 94 a is disposed in a front position of the left end portion of the intake port 93 within the opening width of the intake port 93, and the second joint portion 94 b is an intake port within the opening width of the intake port 93. It is arranged at the front position of the right end portion of 93.

  Here, in the present embodiment, the feeder house 60 is connected to the left side of the platform 21 via the intake port 93 so as to be connected to the left side of the platform 21 because the operation unit 7 is disposed on the right side of the machine body. ing. Therefore, the lateral width of the one-side auger forming body 91 and the lateral width of the intermediate auger forming body 99 are relatively short, and the lateral width of the other-side auger forming body 92 is relatively long.

  In addition, the intermediate auger forming body 99 has a greater scratching force than the one side auger forming body 91, and the intermediate auger forming body 99 has a higher scratching force than the other auger forming body 92. The one-side auger forming body 91 having a relatively short width causes the harvested cereals to be laterally transported to the intake port 93 of the transport unit 4 and taken into the intake port 93. The other side auger forming body 92 having a relatively long width and the amount of the cereal to be made are transported horizontally to the intake port 93 of the transport unit 4 and taken into the intake port 93. The amount of cereals to be made is equalized, and the cereals are evenly and well-balanced and smoothly taken into the intake port 93 from the left and right sides of the stirrer auger 13 and are collectively transported by the transport unit. I am doing so.

  Therefore, the intermediate auger forming body 99 has a greater scratching force than the one side auger forming body 91, and the intermediate auger forming body 99 has a higher scratching force than the other auger forming body 92. By increasing the size, the cereals do not stagnate even on the relatively short one-side auger forming body 91 side, so that the transport efficiency of the cereals to the transport unit 4 can be ensured satisfactorily. Further, it is possible to ensure good transport efficiency on the other auger forming body 92 side. Furthermore, since the scrambling force of the one-side auger forming body 91 is greater than the scrambling force of the other-side auger forming body 92, the conveyance performance at the junction point formed immediately before the intake port 93 is achieved. Can be improved.

  Here, as described later, the magnitude of the rotational speed is set to the rotational speed of the intermediate auger forming body 99> the rotational speed of the one-side auger forming body 91> the rotational speed of the other-side auger forming body 92 as will be described later. is doing. That is, the rotation force of the intermediate auger forming body 99 is larger than the rotation speed of the one-side auger forming body 91, and the intermediate auger forming body 99 has a scratching force for scraping the cereal into the intake port 93. The side auger forming body 91 is set to be larger than the scraping force for scraping the cereal into the inlet 93. Further, the rotation force of the intermediate auger forming body 99 is larger than the rotation speed of the other side auger forming body 92, and the intermediate auger forming body 99 has a stinging force for scraping the cereal into the intake port 93. The side auger forming body 92 is set to be larger than the driving force for scraping the cereal cake into the inlet port 93. Then, the rotational speed of the one-side auger forming body 91 is made larger than the rotational speed of the other-side auger forming body 92 so that the grains are evenly balanced from the left and right sides of the scraping auger 13 to the intake port 93. And it tries to be taken in smoothly. As a result, the cereal can be efficiently conveyed from the scraping auger 13 to the FH conveyor 14.

  On the outer peripheral part of the forming body main body 71c of the intermediate auger forming body 99 opposed to the front of the intake port 93, a picking finger 53 is provided so as to be able to appear and disappear in the radial direction. That is, as shown in FIG. 5, the take-up auger 13 is pivotally supported by the auger support wall 39 of the platform 21 and the first bearing 105 a at the right end of the one-side auger forming body 91. A moving shaft 95 and a second rotating shaft 96 pivotally supported at the central portion of the joint portion 94 between the intermediate auger forming body 99 and the other auger forming body 92. A plurality of scraping fingers 53 are provided radially on the outer peripheral portion of the third rotation shaft 97 provided so as to be eccentrically rotatable.

  In this way, each of the scraping fingers 53 is scraped while catching the harvested cereals stored in the platform 21 with the rotation of the intermediate auger forming body 99 and transferred to the intake port 93 of the transport unit 4. Like to do.

  As shown in FIG. 4, a planetary gear mechanism 100 is disposed at the right end portion of the intermediate auger forming body 99 as one form of the transmission unit. The planetary gear mechanism 100 includes a single sun gear 101, three planetary gears 102 that mesh with the outer periphery of the sun gear 101, an internal gear 103 that meshes with each planetary gear 102, and the like.

  The sun gear 101 is integrated with the second rotating shaft 96 of the scraping finger 53 in the left end portion of the other auger forming body 92. That is, the second bearing 105b is disposed in the center of the left end portion of the other auger forming body 92, and the second rotating shaft 96 of the scraping finger 53 is pivotally supported on the second bearing 105b. A sun gear 101 is fixed around the second rotation shaft 96.

  An input shaft 107 protruding from the left end of the other auger forming body 92 is connected to the center of each planetary gear 102. Further, the outer peripheral portion of the internal gear 103 is integrated with the main body portion of the intermediate auger forming body 99.

  The other auger forming body 92 receives the rotation of the engine E and rotates around the other auger shaft 70 in the same manner as when driving a normal scraping auger. Further, the three input shafts 107 provided at the left end portion of the other side auger forming body 92 are rotatable with the other side auger forming body 92 about the other side auger shaft 70. Thus, when the other auger forming body 92 rotates, the three input shafts 107 also rotate, and the planetary gear 102 rotates around the fixed sun gear 101. And the internal gear 103 which meshes with the planetary gear 102 also rotates, and the main body of the intermediate auger forming body 99 interlockingly connected to the internal gear 103 becomes rotatable.

  The rotation speed ratio between the intermediate auger forming body 99 and the other auger forming body 92 can be arbitrarily set according to the number of teeth of the planetary gear mechanism 100. For example, the number of teeth a of the sun gear 101 is 16T, the number of teeth b of the planetary gear 102 is 16T, and the number of teeth c of the internal gear 103 is 48T. The sun gear 101 is fixed, the planetary gear 102 is input, and the internal gear 103 is output. In this case, the speed ratio (input / output) is speed ratio = c / (a + c). Therefore, if the rotational speed of the input-side planetary gear 102 is 1, the rotational speed of the output-side internal gear 103 is 1.3333. For example, when the other auger forming body 92 is rotated at a rotation speed of 158 rpm, the intermediate auger forming body 99 can be rotated at 210.7 rpm.

  As a result, the other-side auger forming body 92 can be rotated only by inputting the power from the engine E to the other-side auger forming body 92. Further, the intermediate auger forming body 99 can be rotated at a higher rotational speed than the other auger forming body 92 via the planetary gear mechanism 100.

  Further, the power of the drive side shaft 22 of the FH conveyor 14 is input to the one side auger forming body 91 via the one side auger transmission mechanism 68. That is, as shown in FIGS. 4 and 5, the one-side auger transmission mechanism 68 extends the intermediate shaft 67 outward from the left side wall of the feeder house 60, while the intermediate shaft 67 and the one-side auger are formed. A second auger transmission chain 66c is wound between the one-side auger drive shaft 82 of the body 91 via sprockets 66a and 66b. Thus, the one-side auger transmission mechanism 68 transmits power from the drive-side shaft 22 of the FH conveyor 14 to the one-side auger drive shaft 82 to rotate the one-side auger forming body 91.

  As a result, the other-side auger forming body 92 can be rotated only by inputting the power from the engine E to the other-side auger forming body 92. Further, the intermediate auger forming body 99 can be rotated at a higher rotation speed than the other auger forming body 92 via the planetary gear mechanism 100. In this way, the intermediate auger forming body 99 and the other side auger forming body 92 are made different in the number of revolutions, and the intermediate auger forming body 99 has a larger scratching force than the other side auger forming body 92. By doing so, the stagnation of the culm in the intermediate auger forming body 99 can be reduced.

  As described above, the operation of the intermediate auger forming body 99 is controlled by the magnitude of the rotation speed of the intermediate auger forming body> the number of rotations of the one side auger forming body 91> the number of rotations of the other side auger forming body 92.
