Further, by adopting the high friction type, the grip force can be improved, and it is possible to suppress the posture of the crop S1 from collapsing even when the crop S1 is transported at high speed. The high friction type belt is a conveyor belt in which a material having high friction resistance such as sponge is used for the surface of the belt. The conveyor belt 12C is circulated so that the upper side moves in the transport direction A1.

As shown in FIG. 3, the surface of the conveyor belt 12C is a mounting surface (second mounting surface) 12D on which the true leaf S5 side of the crop S1 is placed. Therefore, the crop S1 is placed lying down over the first mounting surface 11D and the second mounting surface 12D.

The tubular portion 61a is formed in a hexagonal tubular shape and is housed in the cover cylinder 63. The cover cylinder 63 is fixed to the cylinder portion 61a (support shaft 61) and rotates integrally with the cylinder portion 61. The prepared crop S1 moves on the outer circumference of the cover cylinder 63. The cover cylinder 63 is formed in a cylindrical shape. As a result, the prepared crop S1 transported by the second transport body 12 can be transported without being damaged.

A hexagonal columnar first transmission shaft 64 is fitted inside the tubular portion 61a. The tubular portion 61a and the first transmission shaft 64 rotate integrally around the axial center and are relatively movable in the axial direction.

Further, since the leaf removing mechanism 17 is driven by a driving unit different from the first driving unit M1 that drives the transport device 3, the cutting member 14, the mud removing mechanism 15, and the pretreatment mechanism 16, crop preparation is performed. The entire leaf removing mechanism 17 including the drive unit (second drive unit M2) and the transmission mechanism 166 can be mounted on the movable frame 167 separately from the other devices mounted on the machine 1.

Next, the second side surface portion 21 will be described with reference to FIGS. 31 to 33.
FIG. 31 shows a side view of the second side surface portion 21 as viewed from the outside (right side) of the machine width. FIG. 32 is a rear sectional view of the second side surface portion 21. FIG. 33 shows a side view of the discharge chute 31 as viewed from the outside of the machine width.
As shown in FIGS. 31 and 32, the second side surface portion 21 is a cover wall portion arranged on the side of the leaf removing mechanism 17 in the machine width direction B1. The main cover 30 is formed in a size that covers the right side of the support frame 67. The front end, rear end, and upper end of the main cover 30 are attached to the support frame 67. The lower end portion of the main cover 30 is attached to the second frame member 5b via the attachment member 216 fixed to the lower end portion.

The discharge port 29 is formed in a rectangular shape in a side view by the first edge portion 29a to the fourth edge portion 29d. The first edge portion 29a is the leading edge portion of the rectangular notch formed in the front-rear central portion of the main cover 30, and the second edge portion 29b is the trailing edge portion of the rectangular notch. The edge portion 29c is an upper edge portion of the rectangular notch. The fourth edge portion 29d is the upper end portion of the mounting member 216. The discharge port 29 has a size corresponding to the open portion 67D shown in FIG. 22 and is at a position corresponding to the open portion 67D in the machine width direction B1. Therefore, the discharge port 29 is formed to have a size from the mud removing mechanism 15 to the leaf removing mechanism 17 via the pretreatment mechanism 16, and is skipped from the leaf removing mechanism 17 and passed through the open portion 67D. Is a passable opening.

As shown in FIG. 32, the discharge chute 31 is a cover that covers the discharge port 29 from the outside of the main cover 30. As shown in FIG. 33, the discharge chute 31 has a main plate 217, a first block wall 218, and a second block wall 219.
As shown in FIG. 32, the main plate 217 has an inclined wall 217a and an extended wall 217b. The inclined wall 217a is a wall portion corresponding to the discharge port 29 in the machine width direction B1 and is away from the leaf removing mechanism 17 from the third edge portion (upper edge portion) 29c side of the discharge port 29 downward. It is formed in an inclined shape that shifts to (right). The extended wall 217b extends downward from the lower end of the inclined wall 217a.

The first blocking wall 218 is a wall portion extending from the front edge side of the main plate 217 toward the main cover 30. In other words, the first blocking wall 218 extends from one end side edge of the inclined wall 217a in the direction along the upper edge 29c of the discharge port 29 to the main cover 30. The second closed wall 219 is a wall portion extending from the trailing edge side of the main plate 217 toward the main cover 30. In other words, the second closing wall 219 extends from the other end side edge portion of the inclined wall 217a in the direction along the upper edge portion 29c of the discharge port 29 to the main cover 30. Between the lower edge portion of the first block wall 218 and the second block wall 219 is an open portion 220 that is open downward.

The unnecessary leaves S4 that have been blown from the leaf removing mechanism 17 and passed through the discharge port 29 come into contact with the inclined wall 217a and fall into the storage container 32. In other words, the discharge chute 31 drops the leaf S4 that has passed through the discharge port 29 downward. Further, since the inclined wall 217a is inclined so as to move away from the leaf removing mechanism 17 as it goes downward, the unnecessary leaf S4 that has passed through the discharge port 29 smoothly changes its direction and falls downward. A part of the unnecessary leaves S4 that have passed through the discharge port 29 falls into the storage container 32 in a parabolic manner.

Further, by providing the discharge chute 31 on the side surface of the cover frame 13, a part of the storage container 32 is arranged so as to protrude outside the machine width from the main cover 30. This makes it easier to see the inside of the storage container 32, and the amount of the stored unnecessary leaves S4 and the like can be easily confirmed.

That is, the upper end side of the discharge chute 31 is pivotally supported by the main cover 30 and can swing up and down, and the discharge port 29 can be opened and closed by swinging up and down. By opening the discharge chute 31, the inside of the cover frame 13 can be easily visually recognized through the discharge port 29 and the open portion 67D. That is, the discharge port 29 and the open portion 67D can be used as inspection ports.

A first contact member 222A that comes into contact with the outer surface of the main cover 30 is attached to the front surface of the first closing wall 218. A second contact member 222B that comes into contact with the outer surface of the main cover 30 is attached to the rear surface of the second closing wall 219. The first contact member 222A and the second contact member 222B have magnets, and the discharge chute 31 is fixed to the main cover 30 by the force attracted by the main cover 30 to the magnets.

The discharge chute 31 may be housed inside the main cover so that the discharge chute 31 does not get in the way when the crop preparation machine 1 is moved.

The letter J1 of M is provided between the adjacent first lines 232A. The first line 232A can identify whether the size of the crop S1 is the first size (S size) or the second size (M size) larger than the first size. That is, when the size of the crop S1 is the size between the reference line 233 and the right end edge 234a of the first line 232A, it is the first size. Further, when the size of the crop S1 is larger than the size from the reference line 233 to the right end edge 234a of the first line 232A and smaller than the size from the reference line 233 to the left end edge 234b of the first line 232A, the second The size.

The second line 232B is provided at a distance to the left from the first line 232A. The second line 232B has a predetermined width W5 in the machine width direction B1 and is provided intermittently over the circumferential direction of the carry-out belt 9C. A 2L character J3 is provided between the adjacent second lines 232B. Further, the letter J2 of L is provided between the letter J1 of M and the letter J3 of 2L. The second line 232B can identify whether the size of the crop S1 is a third size (L size) larger than the second size or a fourth size (2L size) larger than the third size. That is, when the size of the crop S1 is larger than the size from the reference line 233 to the left end edge 234b of the first line 232A and smaller than the size from the reference line 233 to the right end edge 235a of the second line 232B, the third The size.

The identification line 232 (first line 232A, second line 232B, third line 232C) may be continuously provided over the circumferential direction of the carry-out belt 9C.
The size of crop S1 may be identified based on either the width or the number of lines, or may be identified based on both the width and the number of lines. Further, the line is not limited to the width and the number described above, and various design changes can be made. For example, the number of lines may be one or two, or four or more. Further, the widths of the plurality of lines may be set to the same width. In short, it suffices if the size of crop S1 can be identified.

Next, the relay roller will be described.
As shown in FIG. 3, the relay roller 10 is provided between the second transport body 12 and the carry-out portion 10. The relay roller 10 is provided so that the length of the machine width direction B1 is slightly smaller than the width of the machine width direction B1 of the carry-out portion 9 and extends from the left side to the right side of the carry-out portion 9.

The transport speed of the relay roller 10 is the same as the transport speed of the transport unit 7, or faster than the transport speed of the transport unit 7. Further, the transport speed of the carry-out unit 9 is the same as the transport speed of the relay roller 10 or faster than the transport speed of the relay roller 10. That is, the transfer speed of the relay roller 10 is equal to or higher than the transfer speed of the transfer unit 7, and the transfer speed of the carry-out unit 9 is equal to or higher than the transfer speed of the relay roller 10. As a result, the prepared crop S1 can be smoothly transported.

The carry-out portion 9 can swing up and down around the center of rotation of the pulley 9A. That is, the carry-out unit 9 has a transport position X5 (a position shown by a solid line in FIG. 1), which is a position for transporting the crop S1, and a flip-up position X6 (a virtual line in FIG. 1), which is a position flipped up from the transport position X5. The position can be changed to (the position shown). In other words, the carry-out portion 9 can swing upward around the start end side.
As shown in FIG. 1, the crop preparation machine 1 includes a support device 239 that supports the carry-out portion 9 at the transport position X5. The support device 239 has a support member 91 formed by a rod body. The lower end of the support member 91 is pivotally supported by the bracket member 26.

As shown in FIG. 35, the upper end of the support member 91 is fixed to the middle portion of the guide member 240 formed by the rod body extending in the machine width direction B1.
As shown in FIGS. 38 and 39, one end of the guide member 240 is inserted with the first guide groove 242A formed in the first guide plate 241A. The first guide plate 241A is fixed to the first frame F1 (see FIG. 35). The other end of the guide member 240 is inserted with the second guide groove 242B formed in the second guide plate 241B. The second guide plate 241B is fixed to the second frame F2 (see FIG. 35). The first guide groove 242A and the second guide groove 242B are elongated grooves that are long in the longitudinal direction of the carry-out portion 9.

As shown in FIGS. 38 and 39, the guide member 240 is located at one end (rear end) of the first guide groove 242A and the second guide groove 242B when the carry-out portion 9 is located at the transport position X5. There is. As a result, the downward swing of the carry-out portion 9 is regulated. When the carry-out portion 9 is swung upward from the transport position X5, the guide member 240 moves in the first guide groove 242A and the second guide groove 242B to the other end side (front end side), and the carry-out portion 9 Allows upward swing.

As shown in FIGS. 38, 39, and 40, the support device 239 has a holding mechanism 243 that holds the transport unit 9 at a position that swings upward (jump-up position X6). The holding mechanism 243 is arranged at the front portion of the first guide plate 241A, and has a lock member 243 and an urging member 246. The lock member 243 is made of a plate material and has a gripping wall 245a and an engaging wall 245b. The gripping wall 245a is located on the lower surface side of the guide member 240 and comes into contact with the protrusion 244 formed on the guide member 240. The engaging wall 245b extends from the inner end of the gripping wall 245a in the machine width and is located on the side of the first guide plate 241A. The front portion of the engaging wall 245b is attached to a tubular member 248 fixed to the first guide plate 241A by bolts 247. The engaging wall 245b (lock member 245) is rotatably supported by the tubular member 248 around the axis in the machine width direction B1. A hook-shaped engaging portion 245c that can be engaged with the guide member 240 is provided at the rear portion of the engaging wall 245b.

The urging member 246 is composed of a torsion coil spring, and the tubular portion of the coil spring is fitted to the outside of the tubular member 248 so as to be relatively rotatable. One end 246a of the urging member 246 is hooked on the first guide plate 241A, and the other end 246b is hooked on the engaging wall 245b. The urging force of the urging member 246 urges the lock member 243 upward (in the direction of arrow a1 in FIG. 38).

As shown in FIG. 38, when the carry-out portion 9 swings upward, the guide member 240 moves to the front side. When the guide member 240 moves forward and comes into contact with the engaging portion 245c, the lock member 243 swings in the direction of arrow a2 and escapes, allowing the guide member 240 to pass through.
As shown in FIG. 40, when the carry-out portion 9 is located at the flip-up position X6, the guide member 240 is located at the front end of the first guide groove 242A. Then, the lock member 243 returns to the original position by the urging force of the urging member 246, and the engaging portion 245c engages with the guide member 240. As a result, the downward swing of the carry-out portion 9 is restricted, and the carry-out portion 9 is held at the flip-up position X6.

As described above, the carry-out unit 9 can be flipped up and locked with one touch. In other words, the carry-out portion 9 can be automatically locked to the flip-up position X6 by the operation of swinging upward.
When the carry-out portion 9 is returned from the accommodation position X6 to the transport position X5, the grip wall 245a is gripped and the lock member 243 is swung away from the guide member 240 (in the direction of arrow a2 in FIG. 38) to swing the guide member 240.
