An intermittent drive shaft 28 for the mechanisms 13 and 14 is interlocked via a second transmission chain 29, so that the needle 10, the knotting mechanism 12, both ejection mechanisms 13 ,
14 is configured to be driven intermittently. In order to install the knotting mechanism 12 and the primary release mechanism 13 , a case 31 is connected to the upper part of the binding case 30 and protrudes forward from the binding case 30 and houses the transmission mechanism 22 for the pulling device 3. The front end side vertical case portion 3 of this transmission case 31
1A, a case 32 in which the knotting mechanism 12 is installed;
are fixedly connected to each other, and the intermittent drive shaft 28
from the binding case 30 to the transmission case 31
The intermittent drive shaft 28 is erected so as to pass through the horizontal case portion 31B and the knot case 32 of the intermittent drive shaft 28.
A pair of release arms 13 of the primary release mechanism 13 are attached to shaft portions located on both upper and lower surfaces of the knot case 32.
A and 13B are installed. These discharge arms 13A, 13B utilize the contact pressure with the stalk culm bundle during the latter half of the stalk culm discharge operation to
It is configured to escape from and move. The secondary discharge mechanism 14 is constructed as follows. A member 35 for slidably inserting and supporting the intermediate portion of the secondary discharge arm 15 is pivotally attached to a pin 34 which is provided at the upper end of the intermittent drive shaft 28 at an eccentric portion of a disc-shaped rotating body 33. In addition, one end of the secondary discharge arm 15 is pivotally connected to one end of a reciprocating swing link 36 which is pivotally connected to a fixed part beside the rotation path of the rotary body 33, and which is pivotally connected to the pin 34. The other end of the link 37 is connected to the reciprocating swing link 36
The secondary discharging arm 15 is pivotally connected near one end, so that the secondary discharging arm 15 is moved inside the collecting section 8 by a crank movement accompanying the driving rotation of the rotating body 33 and a sliding movement with respect to the supporting member 35. It is configured to perform forced circulation motion. Although the embodiments have been described above, the main feature of the present invention is that the pulling device 3 is provided on the top of the binding case 30 of the binding device 5 in a state that protrudes forward from the binding case 30. A case 31 in which the transmission mechanism 22 is installed is connected, and the case 32 in which the knotting mechanism 12 is installed is fixedly connected to the front end side vertical case portion 31A of the transmission case 31.

As a result, the following effects were obtained. That is, the transmission case 31, which is configured to transmit power to the pulling device 3 without interfering with the installation of the reaping device 4, is replaced with the knot case 3.
2 mounting member and a support member for the intermittent drive shaft 28 which is erected from the binding case 30, as well as the ejection arm 13 of the primary and secondary ejection mechanisms 13 and 14 .
It was possible to reduce the number of parts by using it as the supporting member for A, 13B, and 15. Furthermore, the transmission case 31 and the knot case 32 form a U-shaped strong frame, and the case portion, which receives a huge load through the pair of upper and lower discharge arms, is made of thin-walled material and is lightweight and inexpensive. However, it can be constructed to be durable without deformation or damage, and in addition,
Coupled with the fact that the support span of the intermittent drive shaft 28 can be made as small as possible, the mounting strength of the knotting mechanism and the pair of upper and lower release arms can be made sufficiently large by simplifying the structure. .
