However, the side surface portion 127 of the convex portion 126 is gently inclined so as not to be caught when dragging.

Next, the operation of the present embodiment will be described.

In operation, as shown in FIG. 4, the roll baler 1 is pulled forward by the tractor T and moved forward. In the compression packing apparatus 5, the crop is picked up by the pick-up section 72 and is put into the compression chamber 19, and is sequentially formed into a cylindrical shape. To be molded. At this time, in the bale receiving device 8, the frame lifting cylinder 106 is extended, and the frame 101 is rotated upward so that the field is not dragged.

During this operation, when the bale diameter increases to some extent and a roll bale B having a predetermined compression density is formed, a buzzer sounds and the operator stops the tractor T. Then, a winding member such as a string is automatically wound around the outer periphery of the roll bale B, and packing is performed.

Thereafter, as shown in FIG. 1, the operator operates the first lever (not shown) of the tractor T to contract the frame lifting cylinder 106, and the bail receiving device until the rotating disk 119 contacts the ground. 8 is rotated downward. Then, the second lever (not shown) is operated to contract the cylinder 27 so as to expand the gate 37 rearward and upward. Then, the roll bale B of the compression chamber 19 is discharged and rolls down on the frame 101, and stops at the lowest valley position on the frame 101 as shown. At this time, the roll bale B is held at a predetermined height above the ground without touching the field. Thereafter, the second lever (not shown) is operated again to extend the cylinder 27 and close the gate 37. In this way, the traveling of the tractor T is started again, and the compressing / packaging device 5 is operated as necessary to restart the harvesting operation.

At this time, the bale receiving device 8 on which the roll bale B is placed is pulled by the compression packing device 5 and dragged on the field. It is the rotating disk 119 that slides on the ground. However, since the rotating disk 119 has a disk shape, especially a disk shape, the contact pressure is lower than that of the wheel, and the disk 119 can rotate freely around the vertical axis 120. Even in a poorly drained place, the rotating disk 119 can move in the field so as to slide while rotating. Thereby, the bail receiving device 8 can be moved smoothly.

In this way, the roll bale B is temporarily placed on the bale receiving device 8 and travels, and is moved to a place where there is no water, such as a ridge, without getting wet. Then, the third arm (not shown) of the tractor T is operated toward the person who unloads the roll bale B, and the lift arm elevating cylinder 11 is operated.
Extend 2 Then, as shown by 107 'in FIG.
The lift arm 107 rotates upward with the roll bale B placed thereon, and the roll bale B rolls down on the lift arm 107 and is discharged to the unloading place.

At this time, the bracket 110 is
Is slightly protruded above the rear side of the cross beam 108 and relatively behind the cross beam 108, so that the roll bale B does not catch on the cross beam 108 at the final stage of dropping, and
It rolls on 10 and is guided by this to smoothly discharge. That is, the roll bale B is discharged in the direction of the upper surface 110a of the rearward projecting portion of the bracket 110.

As described above, the roll bale B after packing can be temporarily placed and moved by the bale receiving device 8, so that the roll bale B can be moved to a dry place without moisture and then discharged. It is possible to prevent the bale B from being discharged to the place where it was wiped and to prevent the bale B from getting wet with water. In addition, since the harvesting and packing operation can be resumed in this temporarily placed state, the operation efficiency can be improved.

Further, since the discharge height position H (see FIG. 1) is higher than a normal roll baler, the following effects can be obtained. That is, when the bale is wrapped in a later step, the bale can be directly loaded on the wrapping machine without using another machine such as a bale gripper (a device in which a bale gripper is attached to a front loader). Also, the bale can be directly loaded on a transport device such as a light truck or a transport vehicle. In addition, paddy ridges are generally higher than the field scene, but veil can be discharged directly to such places.

The embodiments of the present invention are not limited to those described above. For example, each of the above-mentioned cylinders can be a hydraulic cylinder, and in the above description, each cylinder is operated by operating a lever for each cylinder. However, if there is only one hydraulic system, a three-way switching valve It is possible to operate the common lever after manually switching it.

Further, automation can be considered in various parts such as automatically closing the gate 37 after lowering the bale receiving device 8.
