FIG. 1: is a schematic side view which shows the whole structure of the crop preparation machine 1 which concerns on this embodiment. FIG. 2 is another schematic side view of the crop preparation machine 1. FIG. 3 is a schematic plan view of the crop preparation machine 1.
First, the configuration of the crop preparation machine 1 will be schematically described with reference to FIGS. 1 to 3.
The crop preparation machine 1 is a machine that performs preparation processing of the crop origin S2 side of the crop S1 shown in FIG. 3. The stock origin S2 side of crop S1 includes stock origin S2 and root S3 of crop S1.

The crop S1 is, for example, harvested leafy vegetables (non-heading leafy vegetables, soft vegetables) such as spinach, komatsuna, chrysanthemum, pakuti.
The preparation process is, for example, "root cutting", "stock cutting", "sludge removal", "pretreatment before removal of leaves", "removal of leaves" or the like. "Root cutting" is preparation processing which cuts and leaves root S3 of crop S1 a little (for example, about 5 mm-about 1 cm). A "stock origin cutting" is preparation processing which cuts stock origin S2 of crop S1, and breaks a stem into pieces. The "slipper" is a preparation treatment to remove the mud earth attached to the stock origin S2 of the crop S1. The “pretreatment before removal of leaves” is a preparation treatment in which the leaves to be removed are moved to the root side. "Removal of leaves" is a preparation process for removing unnecessary leaves (also referred to as unnecessary leaves) S4 such as cotyledons and lower leaves of the crop origin S2 side of the crop S1.

As shown in FIG. 1, the crop preparation machine 1 transports the crop S1 in the direction of arrow A1 (transport direction) from the one end side E1 toward the other end side E2, and performs crop preparation processing on the way of transport.
In the embodiment of the present invention, the upstream side of the transport direction A1 is described as the front of the crop preparation machine 1 (arrow A2 direction), and the downstream side of the transport direction A1 is as the rear of the crop preparation machine 1 (arrow A1 direction). Further, the left side of the crop preparation machine 1 will be described as the left, and the right side as the right. A horizontal direction intersecting (orthogonal to) the conveyance direction A1 will be described as the machine width direction B1. The direction from the central portion in the machine width direction B1 of the crop preparation machine 1 to the left or to the right will be described as the machine width outward. In other words, the machine width outward is a direction away from the center of the machine width direction B1 of the crop preparation machine 1 in the machine width direction B1. The direction opposite to the machine width outside will be described as the machine width inside. In other words, the machine width inward is the machine width direction B1 and a direction approaching the center of the machine width direction B1 of the crop preparation machine 1.

Moves in the machine width direction B1. That is, the width changing mechanism 38 moves the second carrier 12 in the machine width direction B1 with respect to the first carrier 11. The distance W1 between the first and second carriers 11 and 12 can be changed by moving the second carrier 12 in the machine width direction B1 with respect to the first carrier 11 (adjacent to and separated from each other). . Thereby, the width in the machine width direction B1 of the transport unit 7 can be changed.

By changing the width in the machine width direction B1 of the transport unit 7, the width of the transport unit 7 can be made to correspond to the size of the crop S1 (the length of the crop S1). Moreover, it can respond to crop S1 with volume.
As shown in FIG. 10, the opening part 28 is located in the side (left side) of the 2nd conveyance body 12. As shown in FIG. The second transport body 12 is located on the left side of the machine body 2 and closer to the central portion of the machine body at the minimum width position X1 (see the solid line in FIG. 10) closest to the first transport body 11.

That is, the connection member 81 has a gripable grip portion 82 (the connection portion 82A and the connection portion 82B).
As shown in FIG. 10, the gripping portion 82 is located inside the cover frame 13 and at a position close to the opening portion 28 at the minimum width position X1 of the first transport body 11. Thereby, the grip portion 82 can be gripped through the opening portion 28 and the grip portion 82 can be easily gripped. Further, at the maximum width position X2 of the first transport body 11, the gripping portion 82 is located at a position projecting outward from the cover frame 13 via the opening portion 28. That is, the opening part 28 is the magnitude | size which the connection member 81 can pass.

By providing the open portion 28, the machine width of the crop preparation machine 1 can be made compact, and the corresponding width of the transport unit 7 with respect to the size of the crop S1 can be widened. Further, by providing the opening portion 28 and the grip portion 82, the position adjustment of the second transfer body 12 can be easily performed.
As shown in FIG. 14, the width change mechanism 38 has a lock mechanism 84 that locks the movement of the movable base 37. The lock mechanism 84 is provided on the front side of the movable base 37. The lock mechanism 84 has a first lock piece 84A, a second lock piece 84B, a support plate 84C, a fulcrum pin 84D, a locking rod 84E, and a biasing member 84F.

  As shown in FIGS. 15 and 16, the first lock piece 84A and the second lock piece 84B are arranged in the machine width direction B1 behind the roller frame 40A of the first movable body 40. The first lock piece 84A has a U-shaped notch 85A in the upper part and an engagement part 86A in the lower part, and an insertion hole 87A is formed in the middle part in a penetrating manner. The second lock piece 84B has a U-shaped notch 85B in the upper part and an engagement part 86B in the lower part, and an insertion hole 87B is formed in the middle of the second lock piece 84B in a penetrating manner.

  In the state where the first lock piece 84A and the second lock piece 84B are substantially parallel as shown by the phantom line in FIG. 15 (see the phantom line in FIG. 15), the engagement portion 86A is the left end of the engagement hole 92 , And the engagement portion 86B abuts on the right end of the engagement hole 92. In this state, there is a slight gap between the lock rod 84E and the insertion holes 87A and 87B, and the first lock piece 84A and the second lock piece 84B can be moved relative to the lock rod 84E. .

  As shown in FIG. 14, the biasing member 84F is, for example, a compression coil spring, and is compressed between the upper portions of the first lock piece 84A and the second lock piece 84B. The biasing force of the biasing member 84F biases the upper portions of the first lock piece 84A and the second lock piece 84B in a direction away from each other. Due to this biasing force, as shown by a solid line in FIG. 15, the first lock piece 84A and the second lock piece 84B are inclined such that they move away from each other as they move upward. Thus, the edge portions of the insertion holes 87A and 87B abut on the locking rod 84E. The relative movement of the first lock piece 84A, the second lock piece 84B, and the locking rod 84E in the machine width direction B1 is restricted by the frictional force between the edge of the insertion holes 87A, 87B and the locking rod 84E. Be done. Thus, the movement of the movable table 37 is restricted (locked).

The release lever 83 is disposed on the outer side of the connecting portion 82B, and a base 83a which is a lower portion is pivotally supported by a pin 94. The release lever 83 has an extension 93 b extending downward from the base 83 a.

As shown in FIG. 14, the width change mechanism 38 has an operation mechanism 95 for transmitting the operation of the release lever 83 to the lock mechanism 84. The operating mechanism 95 has an operating wire 96. The operation wire 96 is configured by, for example, a push-pull wire.
One end side of the outer wire 96 a of the operation wire 96 is fixed to the stay 97. The stay 97 is fixed to the lower part of the connecting member 81. The other end side of the outer wire 96 a is connected to one end side of the connection pipe 98. As shown in FIG. 15, the other end side of the connection pipe 98 is connected to the first lock piece 84A. That is, the male screw portion 98a is provided on the other end side of the connection pipe 98, and the male screw portion 98a passes through the notch portion 85A, and the nut 100A and the nut sandwiching the first lock piece 84A in the male screw portion 98a. 100 B is screwed.

As shown in FIG. 14, one end side of the inner wire 96 b of the operation wire 96 is connected to the extension 93 b. As shown in FIG. 15, the other end side of the inner wire 96 b is connected to the locking member 99 located on the lower side of the engagement piece 88 through the inside of the connection pipe 98 and the notch 85 B.
In a state where the lock mechanism 84 locks the movement of the movable base 37 (state shown by the solid line in FIG. 15), the extension 93 b is pulled by the inner wire 96 b and the upper portion of the release lever 83 is inclined so as to separate from the grip 82 (See the solid line in FIG. 14). By gripping the upper portion of the release lever 83 together with the grip portion 82 from this state, the upper portion of the release lever 83 is swung so as to be close to the grip portion 82 as shown by a phantom line in FIG. It is eaten. Then, the upper portions of the first lock piece 84A and the second lock piece 84B swing in the direction in which they approach each other. At this time, the connection pipe 98 moves together with the outer wire 96a to follow the swing of the first lock piece 84A. As a result, as shown by a phantom line in FIG. 15, the first lock piece 84A and the second lock piece 84B become parallel, and the friction between the edge of the insertion holes 87A and 87B and the locking rod 84E. The force is released, and the first lock piece 84A and the second lock piece 84B can move relative to the locking rod 84E. By this, the locking of the movement of the movable base 37 by the lock mechanism 84 is released. When the operating force of the release lever 83 is released, the lock mechanism 84 is locked.

As described above, the movement lock of the movable table 37 can be released by gripping the release lever 83 together with the gripping portion 82, and the positions of the first conveyance body 12 and the pressing mechanism 8 by pushing and pulling the gripping portion 82 as it is. Since the adjustment can be performed, the width adjustment of the transport unit 7 can be performed quickly and easily, and the position adjustment of the pressing mechanism 8 can be performed simultaneously.

The notch R3 is formed in a straight line in the direction orthogonal to the conveyance direction A1 from the blade tip.
The length L2 of the second scraping piece 192B is shorter than the length L1 of the first scraping piece 191B. The width W3 of the second scraping piece 192B is narrower than the width W2 of the first scraping piece 191B. Therefore, the second scraping piece 192B is lower in rigidity than the first scraping piece 191B, and the second trailing scraping portion 189B is more flexible than the second leading scraping portion 188B.

The second preceding scraping unit 188B scrapes the unnecessary leaf S4 in cooperation with the first preceding scraping unit 188A. In addition, the first leading scraping portion 188A and the second leading scraping portion 188B are more rigid than the second scraping piece 192A and the second scraping piece 192B, the first scraping piece 191A and the first scraping piece 191B. First, the large unwanted leaf S4 is scraped off.
