Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention picks up straw grass such as grass and straw scattered in a field by a pickup unit to form a roll-shaped bale at a baler unit, The present invention relates to a roll baler configured to be bound by twine supplied from a binding device.

"Conventional Technology" A conventional roll baler is disclosed in Japanese Patent Application No. Sho 60-9484 (Japanese Patent Laid-Open No. 61-
170316) and Japanese Patent Application No. 60-111746 (Japanese Patent Application Laid-Open No. 61-2681)
As described in the specification of No. 08), roll-shaped bales were bound with twine.

"Problems to be Solved by the Invention" In the conventional technology, the rotation speed of the bale is set to the same rotation speed at the time of bale forming operation and bundling operation,
At the time of forming the bale, the rotation speed was low so that an appropriate forming pressure could be applied to the bale.

Therefore, even if the bale forming is finished and the bundling operation is started,
Despite the fact that bundling at high speed is possible, it is not possible to reduce the time to wind the twain due to the constant low speed twain winding, and when the bale is rotated at a high speed that allows bundling, the bale forming pressure is increased. Is insufficient, the veil is likely to collapse, and in any case, the work efficiency has been reduced.

"Means for Solving the Problems" However, the present invention comprises a baler portion forming a bale, a pickup portion mounted in front of the baler portion, and a binding device for winding twain around the bale, In a roll baler that forms a roll-shaped bale and wraps twain around the outer periphery of the roll baler, the drive speed of the baler portion during the bundling operation is higher than the drive speed of the baler portion during the bale forming operation. is there.

"Function" Therefore, during the bale forming operation, a sufficiently hard bale can be formed as in the conventional case, and the twine bundling time can be shortened as compared with the conventional case to easily improve the work efficiency, which is more functional than the conventional case. And can be handled easily.
