Description

[Detailed Description of the Invention] Industrial Application Field The present invention collects waste straw that has been threshed with a combine harvester and released into the field, and grass that has been cut down on the pasture with a brush cutter and compresses it into a cylindrical bale. This product relates to a self-propelled roll baler that performs packing.

BACKGROUND ART A self-propelled roll baler is known, for example, as described in Japanese Patent Application Laid-open No. 196012/1983, which was filed and published by the applicant of the present invention.

In this known structure, the bail part is composed of a fixed machine frame fixed on the vehicle chassis and a movable machine frame that swings upward with respect to the fixed machine frame to open the internal bale chamber. The bale chamber is divided into upper and lower halves.

In order to take out the compressed and packed bales in the bale chamber, the movable machine frame is swung upwards to open the bale chamber, and then the bales are moved upward from the half bale chamber on the fixed machine frame side. A worker lifts the protruding end face of the bale with both hands and pulls it out upward.

Problems to be Solved by the Invention In the above-mentioned self-propelled roll baler, the comparatively heavy bale that has been compressed and packed must be pulled upwards, making it difficult to take out the bale.

Means to solve problems Therefore, the present invention is configured as follows.

In other words, the cylindrical bail chamber is divided into two approximately vertically by a fixed machine frame 2 fixed on the chassis 1 and a movable machine frame 3 that swings upward relative to the fixed machine frame 2 so that the inside can be opened. 4, and one or both of the disc-shaped side wall plates 5 and 6 regulating both end surfaces of the bale chamber 4 are attached to the movable machine frame 3 side, and a bale leading to the bale chamber 4 is attached to the side of the fixed machine frame 2. A pullout path 7 was formed.

Effect With the above configuration, the bale after compression packing is transferred to the bale chamber 4.
When the movable machine frame 3 is swung upward in order to take the bale out of the machine, the side wall plate 5 that regulates the end of the bale chamber 4 moves upward together with the movable machine frame 3, and the bale chamber 4 is moved to the side. Since it communicates with the bale pull-out path 7 of Since the bale can be removed from the machine while being pulled out, the work is easier than the conventional process of lifting the entire bale.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

The overall arrangement is the same as the conventional one, with a pickup device 9, a bail section 10, and a driving section 11 provided from the front to the rear on a vehicle chassis 1 equipped with a traveling device 8 consisting of a crawler.

The bail section 10 is composed of a fixed machine frame 2 and a movable machine frame 3, and includes a lower bundling device 12 provided on the fixed machine frame 2.
and an upper binding device provided on the movable machine frame 3 (not shown)
These form the peripheral wall of the cylindrical bale chamber 4, and the disc-shaped side wall plates 5 and 6 regulate the end surface of the bale chamber 4.

One side wall plate 5 is fixed to the movable machine frame 3 side, and the other side wall plate 6 is fixed to the fixed machine frame 2 side. In addition, the cover 13 provided on the side of the fixed machine frame 2 has
A bale extraction path 7 is formed in the same arcuate shape as the bale chamber 4, but in a slightly larger arcuate shape.

14 is a bail chamber opening/closing handle for swinging the movable machine frame 3 upward; 15 is a clutch lever for intermittent driving of the lower bundling device 12 and the upper bundling device; 16 is a lever for adjusting the up and down of the pick-up device 9; 17
1 is a steering lever for controlling the traveling device 8, 18 is a clutch lever of the traveling device 8, and 19 is a twine supply device.

In addition, in this embodiment, only one of the side wall plates 5 and 6 regulating the end of the bale chamber 4 is attached to the movable machine frame 3, but both are attached to the movable machine frame 3, and the bale is mounted on both left and right sides. By providing the extraction path 7, the direction of extraction of the bale 20 is not limited to one side, but from both sides, making the operation of removing the bale 20 more efficient.

Further, the opening position of the bail chamber 4 may be not on the rear side of the fuselage as in this embodiment, but on the front side.
