The belt 89 with protrusions rotates in the clockwise direction in FIG.

  Planted crops are caused by the pulling devices 12R, 12C, 12L. The planted crop is latched and conveyed along the right latching and conveying path 157R in the right latching and conveying apparatus 74R, and is latched and conveyed along the central latching and conveying path 157C in the central latching and conveying apparatus 74C. Then, it is latched and conveyed along the left latching and conveying path 157L in the left latching and conveying device 74L.

  At the time of normal cutting operation, each of the locking and conveying devices 74R, 74C, and 74L conveys one set of planted crop. On the other hand, at the time of middle splitting work and surrounding mowing work, the center and left latching and conveying devices 74C and 74L convey one line of planted crop, and the right latching and conveying device 74R is planted for two lines. May carry crops. At this time, the planted crops for the two strips may be moved laterally outward from the conveyance range of the right latch conveyance path 157R in the right latch conveyance device 74R, and conveyed to the right latch conveyance device 74R. Disturbance may occur.

  Therefore, the inclination angle of the right latching and conveying apparatus 74R is made larger than the inclination angle of the central latching and conveying apparatus 74C and the left latching and conveying apparatus 74L, and the length of the right latching and conveying apparatus 74R is set at the center. It is conceivable to extend the conveyance range of the right latch conveyance path 157R in the right latch conveyance device 74R by making it longer than the length of the detent conveyance device 74C and the left latch conveyance device 74L.

  However, the right latching and conveying apparatus 74R has a larger inclination angle from the front and rear direction to the laterally outer side in a plan view than the central latching and conveying apparatus 74C and the left latching and conveying apparatus 74L. The clearance between the leading end portion of 74R and the right pulling device 12R is a gap between the leading end portion of the central locking / conveying device 74C and the central pulling device 12C or the leading end portion of the left locking / conveying device 74L and the left pulling device. Before the protrusion of the belt 83 with the protrusion of the right locking and conveying device 74R locks the planted crop, the planted crop comes off from the right pulling device 12R and becomes larger than the gap with 12L. May come off laterally outwardly from the right locking / conveying path 157R in the right locking / conveying device 74R.

  Therefore, as in the present application, the front end portion of the right engagement conveyance path 157R is positioned laterally outside the first portion 56a of the right connection pipe 56, and the right engagement conveyance path 157R and the first portion of the right connection pipe 56 are located. 56a is crossed in plan view, the first portion 56a of the right connection pipe 56 that intersects the right latching and conveying path 157R receives the planted crop, so that the planted crop is the right latching and conveying device. It is possible to prevent the release from moving in the lateral direction from the right engagement conveyance path 157R at 74R.

  The first portion 56a and the second portion 56b in the right connection pipe 56 are formed in a convex shape toward the inner side. When the first portion 56a and the second portion 56b are linear, bending stress acts on the first portion 56a and the second portion 56b when a reaction force is applied to the right connection pipe 56 when receiving the planted crop. The first portion 56a and the second portion 56b are easily bent. On the other hand, when the first portion 56a and the second portion 56b are convex toward the inner side, compressive stress is likely to act on the first portion 56a and the second portion 56b, and the first portion 56a and the second portion. Deflection is unlikely to occur in 56b.

  Planted crops that are transported by the respective locking and transporting devices 74R, 74C, and 74L, and that are scraped by the right-handed rotary packer 75R, the central-headed rotary packer 75C, and the left-handed rotary packer 75L, It is nipped and conveyed along the right nipping and conveying path in the original conveying chain 78R, nipped and conveyed along the left nipping and conveying path in the left stock former conveying chain 78L, and merges to the center side.

  Thereby, these conveyance apparatuses 73R, 73L, 74R, 74C, and 74L are configured to convey the planted crops to the center side and convey them to the second conveyance apparatus 72, which will be described later.
