The contact portion of the pair of contact restricting bodies so that the contact sound generated when the two contacts are smaller than the contact sound generated when the opposing edges of the pair of cup components contact each other At least one of the contact members is formed of a non-metallic material, and when the pair of contact restricting bodies contact each other, the contact width of one of the pair of cup constituent bodies can be variably adjusted. The restricting body lies in that it can be adjusted with respect to the other contact restricting body.

  Further, according to another technical means of the present invention, a support stay protrudes from each of the pair of cup components, and one contact restricting body includes a fixed nut fixed to one support stay and a contact portion. The screw member and a tightening nut that is screwed to the screw member, and the screw member is screwed to the fixed nut so that the contact portion can be adjusted to be retracted toward the other contact regulating body. The tightening nut is screwed to the screw member so that the screw member is fixed to the one support stay so as not to move, and the other contact restricting body is connected to the other support stay having a screw hole. The part is fixed by a fastener such as a bolt.

Further, according to another technical means of the present invention, a scraper member that slides on the inner surface of the pair of cup components is provided at the tip of the support arm, and the middle part of the support arm is opposed to the opposite edge of the pair of cup structures.

At the same time, the second rotating case 162 rotates around the first rotating shaft 161 in the e direction, and in conjunction with this, the second rotating case 162 rotates around the second rotating shaft 171 at the same speed in the f direction (the direction opposite to the first rotating case 161). In conjunction with this, the vertical moving body 163 rotates relative to the second rotating case 162 around the third rotating shaft 175 in the opposite direction. At this time, the second rotating case 162 is twice as large as the first rotating case 161 with respect to the first rotating case 161 (considering the first rotating case 161 or the first rotating case 161 being fixed). The vertical moving body 163 (the third rotating shaft 175 and the second output gear 174) rotates in the reverse direction at the rotational speed, and the rotational speed of the second rotating case 162 is ½ around the third rotating shaft 175. Therefore, the up-and-down moving body 163 protrudes rearward horizontally without rotating or swinging around the third rotating shaft 175 with respect to the traveling machine body 8 side of the transplanter 1. Move up and down in a fixed posture.

  Each time the vertical motion body 163 moves up and down, the swing cam 264 rotates once with respect to the vertical motion body 163, and the cup support 164 swings up and down around the support cylinder shaft 257, so that the planting cup 13 swings back and forth. One rotation of the swing cam 264 relative to the vertical motion body 164 corresponds to one rotation of the first rotation case 161. When the planting cup 13 is lowered, the head is swung to the front and the head is swung to the rear. As a result, the third rotating shaft 175 (the free end side of the second rotating case 162 and the vertical moving body 163 base end side) moves up and down, so that the planting cup 13 moves up and down with swelling in the front and rear directions. In addition, the planting cup 13 moves up and down with a larger swell.

  Further, one rotation of the opening / closing cam 272 relative to the vertical motion body 163 corresponds to one rotation of the first rotation case 161, and the planting cup 13 descends as the first rotation case 161 rotates. A planting hole is formed in the ridge R when it enters R, and the opening / closing cam 272 pushes the opening / closing swing lever 266 forward to swing the opening / closing swing lever 266 forward, The protruding piece 221 of the opening / closing link 220a is pulled forward through the connecting rod 230, thereby opening the planting cup 13 forward and backward and planting seedlings in the planting holes. Further, when the planting cup 13 rises and the planting cup 13 reaches the top dead center (or near the top dead center) with the rotation of the first rotating case 161, the convex portion of the opening / closing cam 272 opens and closes. The cam swinging lever 266 is detached from the roller body 269 and the cam lever 226 swings back in the backward direction to close the planting cup 13.

  The swing cam 264 and the opening / closing cam 272 are fixed to the free end portion of the second rotating body 162 so as to rotate about the third rotating shaft 175 with respect to the vertical moving body 163, and the vertical moving body Since the cup support 164 and the swing lever for opening / closing 266 are swingably supported by 163, the rotational power on the swing cam side is transmitted to the open / close cam side by a chain transmission mechanism or the like as in the prior art. This eliminates the need for transmission mechanisms such as drive pulleys, driven pulleys, and transmission chains to rotate the open / close cam with respect to the vertical motion body. Therefore, the transplanter can be manufactured easily and inexpensively.

  A support shaft 198 is provided at the free end portion of the second rotating body 162 so as to surround the outer periphery of the third rotating shaft 175, and a swing cam 264 and an opening / closing cam 272 are axially disposed on the support shaft 198. The swing cam 264 and the opening / closing cam 272 are set to 1 around the third rotation shaft 175 with respect to the vertical motion body 163 for each vertical motion of the vertical motion body 163. The swinging cam 264 and the opening / closing cam 272 can be rotated with a very simple support structure so as to correspond to the vertical motion of the vertical motion body 163 with respect to the vertical motion body 163 around the third rotation shaft 175. Can be rotated.

  Further, the cup support 164 and the opening / closing swing lever 266 are disposed apart from each other in the axial direction of the support shaft 198 so as to sandwich the vertical motion body 163, and about the same axis as the vertical motion body 163. One end of the vertical motion body 163 is fixed to the third rotating shaft 175, and the other end of the vertical motion body 163 is connected to the cup support 164 and the swing lever 266 for opening and closing. However, the vertical motion body 163, the cup support body 164, and the swing lever for opening / closing 266 are arranged in a compact manner so that the vertical motion body 163 is made as short and compact as possible. Thus, the cup support 164 and the swing lever 266 for opening and closing can be compactly arranged on both sides of the vertical motion body 163.

  Moreover, in the said embodiment, before the opposing edge of a pair of cup structure bodies 219a and 219b contact | abuts at the time of closing operation of the planting cup 13, the contact regulation bodies 281a and 281b which contact | abut each other are a pair of Since the cup components 219a and 219b are respectively provided, the contact regulating members 281a and 281b are connected to each other before the opposing edges of the pair of cup components 219a and 219b come into contact with each other when the planting cup 13 is closed. In contact with each other, the opposing end edges of the pair of cup components 219a and 219b do not contact each other. In addition, the contact sound generated when the pair of contact restricting bodies 281a and 281b contact each other is more than the contact sound generated when the opposite end edges of the pair of cup components 219a and 219b contact each other. Since one contact portion 286b of the contact portions 286a, 286b of the pair of contact restriction bodies 281a, 281b is formed of a synthetic resin that is a non-metallic material so as to be smaller, Noise generated by the opening / closing operation can be reduced, and no large noise is generated when the planting cup 13 is closed. In addition, one of the contact restriction bodies 281a is variably adjustable so that the separation width between the opposing end edges of the pair of cup constituent bodies 219a and 219b when the pair of contact restriction bodies 281a and 281b are in contact with each other. Can be adjusted with respect to the other contact regulating body 281b, so that the pair of cup components 219a and 219b when the planting cup 13 is closed can be adjusted by adjusting the withdrawal of the one contact regulating body 281a. It is possible to easily and accurately adjust the separation width between the opposite end edges of the two, and there is no trouble in the opening and closing operation of the planting cup 13, which is very convenient.

Further, since soft materials 302a and 302b such as rubber are attached to the opposing edge portions 301a and 301b of the pair of cup components 219a and 219b through which the middle portion of the support arm 297 is inserted, the opening and closing operation of the planting cup 13 is performed. Through the scraper operation by the scraper member 305, it is possible to effectively prevent the soft edges 302a and 301b from causing the opposing edges 301a and 301b of the planting cup 13 to strike the support arm 304 and generate a loud noise. Therefore, noise caused by the opening / closing operation of the planting cup 13 can be prevented.
The present embodiment discloses an example of the present invention, and other types of apparatuses can be adopted as the inter-strain changing apparatus, planting apparatus, seedling supply apparatus, and the like.

  In the embodiment described above, the first rotating body 161 rotatably supported on the machine body side and the second rotating body 162 rotatably supported on the free end side of the first rotating body 161 are provided. In conjunction with the rotation of the first rotating body 161, the second rotating body 162 is rotated in the opposite direction to the first rotating body 161, and the planting cup 13 is placed on the free end side of the second rotating body 162. However, instead of this, the planting cup device of the transplanter to which the present invention is applied supports the planting cup 13 so as to be movable up and down by a link mechanism or the like. The pair of cup components 219a and 219b may be configured to open and close with each other in accordance with the up and down movement.
