The mounting table 91 has a fixed table 92 , an extension table 93 rotatably connected to the fixed table 92 , and a position setting means 94 . , are set at a position where bundles can be placed, as shown by solid lines in FIG. 1, and at a folding position, as shown by phantom lines in FIG. As a result, the mounting table 91 has a wider mounting area when placing bundles, and
When transporting the device, the extension stand 93 can be folded to make it compact. The binding operation in the present invention configured as described above will be described below.

Objects A to be bound that have been harvested in the field are temporarily placed on the object to be bound 80, and a desired number of objects A to be bound are artificially fed onto the transfer path 42, and then the objects A are fed via the operating lever 65. The focusing members 74, 74 of the focusing means 61 are brought into contact with the objects to be bound A, and the objects A are focused and fed into the bundling space 42a.

When the object to be bound is supplied to the string B whose tip end is locked to the holder 9, the needle 6 rotates to the position shown by the imaginary line in FIG. 4, and the string B is wound around the object A to be bound.

The now two strings B wrap around the rotating building 8 (states shown in Figures 11 A and B), and the movable rod 8a operates during the time when the building 8 rotates once from the state of approximately half a rotation. The mouth of the building 8 opens, and the ends of the two wound strings B enter the mouth (states shown in FIG. 11C and D).

Prior to the rotation of the building 8, the drawing rod 25 passes through the side of the building 8 and protrudes forward due to the rotation of the actuating plate 28, and in this state, the building 8 rotates as described above to flatten the drawing rod 25. Side 2
5a and enters the state shown in FIG. 11D. Building 8 has teeth in this state! Since the wheel 20 can be disengaged from the gear portion of the partial bevel gear 18, this state is maintained. The actuating plate 28 is rotating even while the building 8 is stopped, and the drawing rod 25
to return to action.

At this time, the building 8 and the drawing rod 25 are located approximately parallel to each other, and when the claw member 31 passes the side of the building 8, as shown in FIG. It engages with the loop part b of B and begins to pull it out from the tip of the building 8. After that, the actuating plate 28 continues to rotate, and the punching rod 25 moves back, and at the same time, the cam plate 51 comes into contact with the spring plate 52 and is pushed outward, so that the pressing force by the spring plate 52 is no longer applied. The rod 8a rotates to open the building 8 (the state shown in FIG. 11F).

As a result, both ends of the string B, which the claw member 31 is engaging with the loop part b and pulling, are released from the building 8, and the first
This results in a binding string having a knot D as shown in Figure 1G (the object to be tied is not shown) or a binding string with both ends remaining within the knot D. In addition, the string B moves as the needle 6 rotates.
The middle part of the holder 9 is held by the holder 9 while the building 8 is rotating, and is cut by a knife provided on the holder 9 while the building 8 is rotating from C to D in FIG. The string B is separated into the rear end wrapped around the object A and the tip held in the holder 9 to be wrapped next time. Immediately after reaching the position shown in FIG. 11D, it is released from the holder 9, and the knotting/pulling operation and the subsequent operation of releasing both ends of the string are possible as described above.

According to the present invention described in detail above, the focusing means includes a focusing member disposed on the device frame above the binding space so as to be rotatable about the horizontal axis, and a manual handle for rotating the focusing member in the direction of converging the objects to be bound. Since the drive mechanism is provided with a clutch means that interlocks with the focusing member so as to be activated after the focusing operation is completed, the focusing operation can be performed by manually operating the focusing member without directly touching the objects to be bound. Moreover, the clutch means is interlocked with the operation of this focusing member, and the drive mechanism is operated to connect the bundling work, making it possible to perform the bundling and bundling work safely when desired, and to reduce the burden on the target. It can bind objects regardless of their quantity or size, and since the focusing member is located above the binding space, the entire process of the focusing operation can be monitored and the supply amount of objects to be bound can be adjusted.
