2. Description of the Related Art A sugarcane harvester cuts sugarcane with a cutting device provided at a front end of a car body as the car body travels, and conveys the cut sugarcane rearward by a conveyance device in the car body. It is designed to be cut by a cutting device provided on the way.

[0003] Shredded sugar cane is received from a conveyor on an ascending conveyor, and stored in a harvesting bag loaded at the rear end of a vehicle body from the conveyor.

[0004] The harvesting bag is mounted on a rectangular frame provided at the upper end of an arm that swings up and down. Conventionally, the frame and the harvest bag are attached by hooking a ring or a hook provided at an opening at the upper edge of the harvest bag to a plurality of locking pins provided around the frame.

[0005]

However, in the case where the upper edge opening of the harvesting bag is hooked on the frame as described above, when the wind is applied to the empty harvesting bag, the harvesting bag rises and the frame rises. There has been a problem that the ring or hook comes off the locking pin of the body, and the harvest bag falls.

Further, if the upper edge of the harvest bag is attached to the frame via a shackle so that the harvest bag does not drop, it is necessary to remove the screw shaft of each shackle when removing the harvest bag after harvesting. There is a problem that it takes a lot of trouble and the harvest operation rate is reduced.

On the other hand, when the lower part of the four corners of the harvest bag and the frame are connected via a connecting member such as a wire, the lifting of the harvest bag can be stopped. However, there is a problem that it takes time and effort to attach and detach the connecting member.

Therefore, an object of the present invention is to prevent the lifting of the harvest bag by an extremely simple operation, and when the full harvest bag is lowered to the ridge, the lifting preventing means is automatically released. It is an object of the present invention to provide a harvesting bag mounting device which is configured as described above.
