The releasing means 5 and the posture changing means 6 are provided at the rear end of the machine body 2. The discharge means 5 and the posture changing means 6 constitute a discharge portion 7.

  Further, a gauge wheel 9 that travels over the furrows of the field is provided on the holder portion 8 of the machine body 2 so that the position of the gauge wheel 9 can be adjusted in the vertical direction.

  The fuselage 2 has a three-point hitch part 13 composed of a top mast 11 and a pair of left and right lower arms 12, and the three-point hitch part 13 can be attached to and detached from the three-point link part of the tractor via a coupler. It is connected. The three-point hitch portion 13 is fixed to a frame pipe portion 14 that is elongated in the left-right direction. The three-point hitch portion 13 is rotatably provided with an input shaft 15 in the front-rear direction to which power from the tractor is input, and the input shaft 15 is connected to the PTO shaft of the tractor via a joint or the like.

  The root cutting means 3 has a vibration frame 16 that is a frame body that vibrates in the front-rear direction with respect to the machine body 2 as shown in FIGS. Is coupled to the input shaft 15 via the vibration mechanism 18, and the vibration frame 16 is moved back and forth around the pair of left and right support shafts 19 through the operation of the vibration mechanism 18 by the rotation of the input shaft 15. It is designed to rotate and vibrate.

  Further, the root cutting means 3 can move at least up and down with respect to the airframe 2 and abuts on the upper part of the foliage part A1 of the peanut A vegetated on the straw of the field and pushes the foliage part A1 forward to bring the peanut A forward. A contact pipe 21 which is a cylindrical contact body which is in the left-right direction and is in a tilted posture, and a root of a root side portion A2 of peanut A which is arranged below the contact pipe 21 and which is vegetated on the ridge of the field. And a plate-like cut body 22 for cutting the plate.

  The abutment pipe (posture control roller) 21 is used to place the peanut A in a forward tilted posture, and at least in the vertical direction and on the vibration frame 16 via a pair of left and right support shafts 23 facing each other. It is attached so as to be movable in the front-rear direction. A projecting support shaft 23, which is a support portion that supports the left and right ends of the abutment pipe 21, is directed inwardly to a vertical mounting plate 24 that is attached to the lower inner surface of the vibration frame 16 so that the position can be adjusted. It is fixedly protruding.

  The abutment pipe 21 is formed in a cylindrical shape having an opening shape on both end surfaces having circular opening portions 25 on both end surfaces in the left-right direction, and the support shaft 23 is inserted into the abutment pipe 21 from the opening portion 25. The inserted support shaft 23 is in contact with the upper end portion of the inner peripheral surface of the contact pipe 21. That is, the abutting pipe 21 is supported at both left and right ends by only a pair of left and right support shafts 23, and the support shafts 23 can freely move within the opening 25. For this reason, the contact pipe 21 can move freely within a range in which the support shaft 23 does not come out of the opening 25.

  The contact pipe 21 can be in either a left-downward inclined state or a right-downward inclined state by contact with the stem and leaf portion A1 of the peanut A during work (see FIG. 2). That is, for example, when one peanut A of the two strips contacts the left side of the outer peripheral surface of the contact pipe 21, the contact pipe 21 is pushed by the peanut A on the left side and moves upward to the right. When the other peanut A of the two strips is in contact with the right side of the outer peripheral surface of the contact pipe 21, the contact pipe 21 is pushed upward by the peanut A on the right side. Moves to the left-tilting state. When two peanuts A are in contact with the contact pipe 21 at the same time, the contact pipe 21 moves up with the whole being in a horizontal state.

  Further, the contact pipe 21 can be rotated rearward and upward about the support shaft 23 by contact with the stem and leaf portion A1 of the peanut A during operation (see FIG. 4). In some cases, it may rotate 360 degrees or more as the center. When the contact pipe 21 is separated from the peanut A, it returns to its original state by its own weight.

  The cutting body 22 has a pair of left and right vertical mounting plate portions 26 attached to the lower outer surface of the vibration frame 16 so as to be adjustable in position, and a left and right longitudinal shape integrally connecting the lower end portions of both the mounting plate portions 26. And a cutting blade portion 27 such as a tip-down inclined tip metal.

  The front end portion of the cutting blade portion 27 is sharply pointed, and the peanut A after cutting the roots that has fallen forward is lifted to the rear end portion of the cutting blade portion 27 and transferred to the conveyance start end portion of the conveyance means 4. A comb-like lifting body 28 is attached. The lifting body 28 is composed of, for example, a plurality of lifting bars 29 that are inclined downward in the left-right direction, and the soil is directed toward the field from the gaps between the lifting bars 29 adjacent to each other. It comes to fall. The front end portion of each lifting rod 29 is fixed to the rear end portion of the cutting blade portion 27, and the rear end portion of each lifting rod 29 is a free end portion.

  As shown in FIG. 1 and the like, the conveying means 4 conveys the peanut A toward the upper and lower sides while rotating (turning) in a predetermined direction by the power from the input shaft 15 side while maintaining the peanut A in the forward tilted posture. In addition, an endless transport body 31 capable of dropping soil from the gap to the field during the transport is provided. That is, the conveyance body 31 which is a hook conveyance section that hooks and conveys the peanut A has a plurality of claw bodies 33 protruding upward from the conveyance surface 32, and receives and receives the peanut A from the lifting body 28. The peanut A is conveyed with the nail body 33 maintained in the forward-down position.

  The transport body 31 has an endless body 36 such as a plurality of (for example, three) chains parallel to each other that rotate in a predetermined direction by power from the input shaft 15 side. In the endless body 36 at a position spaced in the rotational direction, a plurality of transporting lengths in the left-right direction in which a plurality of nail bodies (scraping nails) 33 hooked on the stalks and leaves A1 of the peanut A are projected. A scale 37 is installed so as to rotate together with the endless body 36. Further, a plurality of longitudinally extending transporting longitudinal members 38 that are not provided with the claw members 33 are arranged so as to rotate together with the endless body 36 at positions spaced in the rotational direction of the endless body 36. Has been.

  In addition, the elongate member 38 without a nail | claw is located between the two elongate bodies 37 adjacent to each other. Each long body 37 with claws has a plurality of claw bodies 33 provided at intervals in the longitudinal direction of the long body 37. A transport surface 32 is constituted by the upper surface of the long body 37 and the upper surface of the longitudinal member 38.

  The endless body 36 is stretched around a drive sprocket 42 that is a drive rotary body fixed to the drive shaft 41 and driven sprockets 44a and 44b that are driven rotary bodies fixed to the driven shafts 43a and 43b. The upper driven sprocket 44a is disposed below the drive sprocket 42, and the endless body 36 has a vertical portion 36a positioned along the vertical direction. In other words, the endless body 36 has the vertical portion 36a at the transport end portion of the transport means 4, so that the peanut A falls due to its own weight at the position of the vertical portion 36a and separates from the nail body 33. It has become.

  Further, the drive shaft 41 and the driven shafts 43a and 43b are rotatably supported by a support frame 45 which is a pair of left and right conveyor side plates facing and spaced apart from each other. The drive shaft 41 is connected via a power transmission means 46. Connected to input shaft 15.

  Further, the claw body 33 is detachably attached to a plurality of positions spaced in the longitudinal direction of the long body 37 by attachment means. As shown in FIG. 10, the claw body 33 is made of, for example, a plate member having an L shape (including a substantially L shape) when viewed from the front, and a mounting plate portion 51 in which a plurality of mounting holes are formed, The mounting plate portion 51 has a rectangular action plate portion 52 that is integrally provided upright so as to be orthogonal to the mounting plate portion 51 at an end portion in the left-right direction.

  The mounting plate portion 51 is formed in, for example, a rectangular plate shape having a longitudinal direction in the transport direction in plan view. The action plate portion 52 is formed, for example, in a plate shape having a trapezoidal shape in which the upper and lower opposite sides are parallel in a side view. The action plate portion 52 has a narrow shape toward the distal end, and the width dimension of the action plate portion 52 gradually decreases from the proximal end side toward the distal end side.

  As shown in FIG. 5 to FIG. 10 and the like, the release means 5 is rotated forward in the predetermined direction by the power from the drive shaft 41 side of the transport means 4, and is tilted forwardly unloaded from the transport end portion of the transport means 4. It is composed of a single discharge roller (reversing disk) 61 that is a horizontal rotary member for releasing the peanut A in a posture toward the rear. In other words, the release roller 61 is made of, for example, a star roller, and is rotated in a predetermined direction around the rotation center axis X in the left-right direction while the peanut A is kept in the forward tilted posture toward the posture changing means 6 side. Let it go.

  The release roller 61 is rotatably supported by the shaft support portion 60 of the machine body 2, and a rotation shaft 63 in the left and right direction in which the rotation center axis X passes through the axis, and the rotation shaft 63 and the rotation shaft 63. And a roller body 64 for releasing the peanut A to the rear while rotating.

  A sprocket 65 is fixed to the left end, which is the axial end of the rotating shaft 63, and a sprocket 66 is also fixed to the left end, which is the axial end of the drive shaft 41. , 66 spans a power transmission chain 67. The rotating shaft 63 is disposed behind the vertical portion 36a of the endless body 36, and is located at substantially the same height as the front driven shaft 43a.

  The roller main body 64 is fixed between the star-shaped hook member 71 and the hook members 71 adjacent to each other in a side view that is fixed to the rotary shaft 63 at positions spaced in the axial direction and hooked on the stem and leaf portion A1 of the peanut A. Further, it is constituted by a cylindrical member 72 having an opening shape at both end faces and a cylindrical shape. The cylindrical member 72 is for preventing the foliage portion A1 from being entangled with the rotating shaft 63.

  The hook member 71 has a star-shaped plate portion 74 in which a plurality of, for example, eight triangular convex portions (hook portions) 73 arranged at intervals in the circumferential direction of the roller body 64 are formed on the outer peripheral portion. A mounting cylinder 75 is projected from the center of the star plate 74, and this mounting cylinder 75 is fixed to the outer peripheral side of the rotating shaft 63 with a bolt 80. An annular stop 76 is projected on the side surface of the star plate 74, and a cylindrical member 72 is fixed to the outer peripheral side of the stop 76. Note that at least the triangular portion 73 of the hooking member 71 is preferably made of an elastic member such as elastically deformable resin or rubber, but may be made of, for example, iron metal.

  On the other hand, the peripheral speed (movement speed) of the outer periphery of the discharge roller 61 is faster than the conveyance speed (movement speed) of the conveyance body 31 of the conveyance means 4. That is, the moving speed of the peanut A based on the rotation of the roller body 64 of the releasing roller 61 is such that the peanut A is appropriately released backward from the claw body 33 of the conveying body 31. It is faster than the moving speed of the peanut A based on the rotation of the carrier 31.

  Further, as shown in FIG. 10, the release roller 61 is disposed in the vicinity of the conveyance end portion of the conveyance means 4, and is emitted from the movement region of the claw body 33 of the conveyance means 4 in a side view. The moving area of the triangular portion 73 of the roller 61 for use overlaps each other.

  As shown in FIG. 5 to FIG. 7 and the like, the posture changing means 6 is changed from the forward-falling posture to the inverted posture by the peanut A released by the releasing roller 61 of the releasing means 5 colliding. It is composed of a guide body (reversing guide) 81 which is a plate-like posture changing chute for dropping the peanut A in the reversed posture toward the field.

  For example, the guide body 81 is arranged such that the two peanuts A vegetated on the field are arranged in a row (including substantially one row) in a reversed posture on the ridge of the field after work. It is made to fall toward the farm field while guiding to the center in the left-right direction. The guide body 81 is made of, for example, a single plate member having a semi-mortar shape, and is attached to the attachment plate portions 83 on both the left and right sides of the body 2 by attachment means (for example, bolts and nuts) 82 so that the position can be adjusted. .

  In addition, the guide body 81 has a guide surface 85 that slides and guides the peanut A in a front-down slanting shape that forms a V-shape (including a substantially V-shape) that opens forward in plan view, and has a lower side. The lower end portion has a dropping port 86 which is an opening for opening crops and drops the peanut A. The guide surface 85 is formed in a smooth curved surface shape so that the peanut A smoothly slides down.

  For example, when one of the two peanuts A collides with the left side of the guide surface 85, the peanut A changes the posture from the forward-falling posture to the inverted posture due to the collision, and then moves to the left side of the guide surface 85. Then, after being guided toward the center of the guide surface 85, it falls toward the field through the center-side drop port 86.

  Also, when the other peanut A of the two items collides with the right side of the guide surface 85, the peanut A changes its posture from the front-down position to the inverted posture due to the collision, and then on the right side of the guide surface 85. After being guided toward the central portion of the guide surface 85, it falls toward the farm field through the central-side drop port 86.

  In addition, the inclination angle α with respect to the horizontal direction of the guide surface 85 of the guide body 81 is, for example, 45 degrees to 75 degrees. In addition, since the state of the peanut A varies depending on the variety, the growing condition, and the like, for example, the inclination angle α of the guide surface 85 may be adjustable so that the state of the peanut A can be dealt with. The guide body 81 is preferably composed of an elastic member such as elastically deformable resin or rubber, but may be composed of, for example, an iron metal plate.

  Next, the operation and the like of the farm work machine 1 will be described.

  When the agricultural machine 1 is moved forward by the traveling of the tractor while the agricultural machine 1 is connected to the tractor, the peanut A vegetated on the straw of the field is first cut by the root cutting means 3. Then, the root side part A2 in the soil is dug up on the ground.

  At this time, the root cutting means 3 cuts the root of the root side portion A2 of the peanut A with the cutting blade portion 27 of the cut body 22 while pushing the stem and leaf portion A1 of the peanut A forward on the outer peripheral surface of the contact pipe 21. Therefore, the peanut A changes from the normal posture in which the foliage portion A1 is located on the upper side to the forward tilted posture in which the foliage portion A1 is located on the front side.

  Then, the peanut A after the root cutting that has fallen forward is lifted by the lifting body 28 in the forward fall position, and is then transported obliquely upward and rearward by the transport body 31 of the transport means 4. The

  At this time, the endless body 36, the long body 37, and the longitudinal member 38 of the transport body 31 do not enter the soil of the straw in the field, and only the claw body 33 of the transport body 31 is in the soil of the straw of the field. It is supposed to enter. For this reason, the soil in the field is not transported on the transport body 31 together with the peanut A, and the endless body 36 is not worn down by contact with the soil in the field.

  And the nail | claw body 33 is caught in the stalk-and-leaves part A1 (mainly the part close | similar to the root side part A2 among the stalk-and-leaves part A1) of the peanut A of the forward-turning posture from which the root was cut | disconnected, The nail body 33 conveys the peanut A on the long body 37 and the longitudinal member 38 obliquely upward and rearward while maintaining the forwardly tilted posture.

  In other words, after the peanut A is scraped up by the nail body 33 of the transport body 31, the nail body 33 enters the foliage portion A1 and remains engaged with the long body 37 and the longitudinal member 38. Then, it is transported in a forward tilted posture (a posture in which the fruit actually faces the front in the transport direction). During this conveyance, the soil adhering to the peanut A falls from the gap between the conveyance bodies 31 onto the field.

  After that, when the peanut A is unloaded from the conveyance end portion of the conveyance body 31 of the conveyance means 4, the peanut A is discharged backward by the discharge roller 61 of the discharge means 5 while keeping the forward tilted posture, and the posture change means 6. It collides with the guide surface 85 of the guide body 81.

  Then, the peanut A changes its posture from the forward leaning posture to the reverse posture based on the momentum of the collision and the inclination angle α of the guide surface 85.

  Then, the peanut A in the inverted posture slides down on the guide surface 85 toward the center side of the guide surface 85, and falls from the drop port 86 onto the field fence. In this way, for example, the two strips of peanuts A vegetated on the field are placed in a single row in the inverted posture on the straw of the field (see FIG. 5).

  In addition, the peanut A placed on the field is naturally dried by ground drying or the like, and then only the fruit of the root side portion A2 is separated and harvested.

  And according to the agricultural machine 1, the root cutting means 3 cuts the root of the peanut A while pushing forward the stem and leaf portion A1 of the peanut A vegetated in the field, and the conveying means 4 cuts the peanut A after cutting the root. The part A1 is conveyed obliquely upward and rearward while maintaining the forward tilted position positioned on the front side, the releasing means 5 releases the peanut A from the conveying means 4, and the attitude changing means 6 releases the peanut from the means 5. In order to make A fall in the inverted posture where the foliage portion A1 is located on the lower side and drop it onto the field, the forward fall posture of the peanut A on the transport means 4 is effectively stabilized by the engagement with the nail body 33, The peanut A can be turned upside down appropriately, and therefore, the peanut A can be put in a properly inverted posture and placed on the field.

  Further, the root cutting means 3 has at least a contact pipe 21 that can move up and down so as to contact the stem portion A1 of the peanut A vegetated in the field and push the stem portion A1 forward. The stem and leaf part A1 of peanut A can be pushed down appropriately.

  Furthermore, since the abutment pipe 21 can be in either a left-downward inclined state or a right-downward inclined state by abutting with the stem and leaf portion A1 of the peanut A, the stem and leaf portion A1 of the peanut A is more Can be pushed down properly. In other words, for example, even if there is a difference in stockout or overgrowth on the left and right or front and back, the stems and leaves A1 of the peanut A can be appropriately pushed down by the tiltable contact pipe 21.

  Further, the guide body 81 of the posture changing means 6 guides the peanut A to the center side in the left-right direction of the guide body 81 so that the plurality of peanuts A vegetated on the field are arranged in a line in a reversed posture on the field. However, since it falls toward the agricultural field, the number of strips of peanut A is halved, and for example, the post-operation can be performed efficiently.

  Further, since the peripheral speed of the discharge roller 61 of the discharge means 5 is faster than the transfer speed of the transfer body 31 of the transfer means 4, the peanut A from the transfer body 31 of the transfer means 4 is directed toward the guide body 81. The peanut A can be reversed more appropriately.

  In addition, the root cutting means 3 of the agricultural machine 1 may be the one shown in FIGS. 11 and 12, for example.

  The abutment pipe (posture control roller) 21 of the root cutting means 3 can move at least up and down with respect to the machine body 2 but is supported by a pair of left and right so as not to be affected by the vibration of the vibration frame 16. It is attached to the frame pipe portion 14 of the airframe 2 via the means 91.

  The abutment pipe 21 is formed in a cylindrical shape with both end faces in the left-right direction closed, and has shaft portions 93 at both end parts in the left-right direction. That is, the abutting pipe 21 is configured by a cylindrical pipe main body portion 92 whose both end surfaces are closed, and a left and right shaft portion 93 projecting from the center portion of both end surfaces of the pipe main body 92. Yes.

  The support means 91 has a substantially U-shaped fixed arm 95 whose upper end is fixed to the left and right ends of the frame pipe portion 14 of the machine body 2, and a rotating arm 96 is attached to the lower end of the fixed arm 95. It is attached so as to be pivotable in the vertical direction around a support shaft (rotation center) 97 in the left-right direction.

  The rotating arm 96 has a plurality of mounting holes 98 arranged in the longitudinal direction, and a support shaft 97 is inserted into one mounting hole 98 selected from the plurality of mounting holes 98. Further, the fixed arm 95 and the rotating arm 96 are connected by a linear member 100 (for example, a chain or a wire) for preventing the lowering to position the contact pipe 21 at a predetermined lower limit position. That is, the upper end portion of the linear member 100 is attached to the hole portion 101 of the fixed arm 95, and the lower end portion of the linear member 100 is attached to the hole portion 102 of the rotating arm 96.

  A shaft portion 93 of the abutting pipe 21 is rotatably attached to the rear end portion of the rotating arm 96. The abutting pipe 21 is a pair of left and right rotations that can be rotated up and down about a support shaft 97. A movable arm 96 is rotatably supported. That is, the abutment pipe 21 can rotate about the shaft 93 with respect to the rotating arm 96 and can rotate up and down about the support shaft 97 with respect to the fixed arm 95.

  In addition, the abutment pipe 21 can be in either a left-downward inclined state or a right-downward inclined state by contact with the stalks and leaves A1 of the peanut A during operation, as in the case shown in FIG. It is. In other words, the pair of left and right turning arms 96 can be individually turned up and down with respect to the fixed arm 95.

  And even if it is the agricultural working machine 1 provided with such a root cutting means 3, the same effect as the agricultural working machine 1 mentioned above can be show | played.

  Moreover, the guide body 81 of the attitude | position change means 6 of the agricultural working machine 1 may be what is shown, for example in FIG. 13 thru | or FIG.

  This semi-mortar-shaped guide body 81, like the one shown in FIG. 5, causes the peanut A released by the releasing means 5 to fall from the forward-down position to the inverted position toward the field. The guide body 81 has a guide surface 85 for sliding and guiding the peanut A in a front-down slanting shape having a V-shape (including a substantially V-shape) opening forward in plan view, and The guide surface 85 is configured by a plurality of planes, which have a drop opening 86 at the lower end, which is a crop outlet that opens downward and drops the peanut A.

  That is, for example, the guide surface 85 has a flat center guide surface portion 85a that faces the front diagonally upward without facing left and right, and a flat left guide that has a right front downward slope that faces the right front diagonally upward. It has a surface portion 85b and a right guide surface portion 85c that is flat and has a left front downward slope that faces diagonally upward to the left. The guide body 81 has a vertical surface 90 formed of a plurality of planes along the vertical direction at the upper part of the front surface.

  And even if it is the farm work machine 1 provided with such a guide body 81, there can exist an effect similar to the farm work machine 1 mentioned above. For example, only the central guide surface portion 85a may be formed in a curved shape, and the guide surface 85 may be configured by a combination of a curved surface and a flat surface. Further, for example, a shape without the vertical surface 90 may be used.

  Further, the release roller 61 of the release means 5 of the farm work machine 1 may be, for example, as shown in FIGS.

  The release roller 61 is composed of, for example, a roller with a protrusion having rubber protrusions 111 that are a plurality of convex portions on the outer peripheral portion, and the peanut A is rotated while rotating in a predetermined direction around the rotation center axis X in the left-right direction. It is released toward the posture changing means 6 while keeping the leaning posture.

  The release roller 61 includes a power transmission chain 67 and a rotary shaft 63 connected to the drive shaft 41 of the conveying means 4 via both sprockets 65 and 66, as shown in FIG. A roller body 64 is provided on the rotating shaft 63 and releases the peanut A to the rear while rotating together with the rotating shaft 63.

  The roller main body 64 has a cylindrical roller main body 112 that is fixed to the outer peripheral side of the rotary shaft 63 and rotates with the rotary shaft 63. The outer peripheral surface of the roller main body 112 has a plurality of axial directions parallel to each other. A longitudinal attachment portion 113 is fixed, and the plurality of attachment portions 113 are arranged side by side at equal intervals in the circumferential direction of the roller body portion 112.

  A plurality of elastic protrusions 111 that are elastically deformable elastic protrusions 111 are attached to each attachment part 113 so as to form two rows along the longitudinal direction of the attachment part 113. The two rows of rubber protrusions 111 attached to each attachment portion 113 gradually increase in distance from the proximal end side toward the distal end side, and have a V shape in a side view. The rubber protrusions 111 for each mounting portion 113 may be one row instead of two rows.

  Further, the peripheral speed of the outer periphery of the discharge roller 61 is faster than the transport speed of the transport body 31 of the transport means 4. As shown in FIG. 18, in a side view, the movement region of the claw body (convex portion) 33 of the conveying means 4 and the movement region of the rubber protrusion (convex portion) 111 of the roller body 64 of the discharge roller 61 are shown. And do not overlap each other.

  And even if it is the farm work machine 1 provided with such a discharge roller (roller with protrusion) 61, there can exist an effect similar to the farm work machine 1 mentioned above.

  Note that the agricultural machine 1 may be, for example, a combination of the configurations of the above-described modifications as appropriate.

  Further, the agricultural machine 1 is not limited to the one that targets two crops (peanut A), and may be one that targets one crop or three or more crops, for example.

  Further, the configuration is not limited to the configuration in which the vibration frame 16 is provided on the airframe 2 so as to be rotatable about the support shaft 19. For example, instead of the vibration frame 16, a fixed frame is fixed to the airframe 2, and A configuration in which a contact body such as the contact pipe 21 is provided may be used.

  Further, the contact body may be, for example, one that only rotates relative to the airframe, one that moves only up and down relative to the airframe, or one that is fixed relative to the airframe.

  Furthermore, the present invention is not limited to a traction type farm work machine connected to a tractor, and may be a self-propelled farm work machine provided with traveling means such as a traveling tire.

  Further, the agricultural product is not limited to peanut A, and may be, for example, sweet potato.
