Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for arranging stocks of a binding device provided in a combine or the like.

2. Description of the Related Art Many combine harvesters are equipped with a cutter or a knotter (bundling machine) at the rear of the machine in order to chop threshed culms and discharge them to a field, or tie them together in predetermined bundles and discharge them to the field. And, in a combine equipped with a binding machine, on the stock base side of the culm transfer passage of the binding machine, a stock base shifting device comprising an endless rotating belt in which the transfer working surface is located closer to the tip as the transfer end side. In addition, there has been provided an arrangement in which the roots of the culms are aligned without causing culm breakage by the root alignment device (Japanese Patent Application Laid-Open No. 64-43127, Japanese Utility Model Publication No.
-20926 publication).

Problems to be Solved by the Invention Grain culms such as rice and wheat have different culm lengths depending on cultivars and cropping patterns (in the case of rice, the culm length is generally 800 mm to 1100 mm). Therefore, when feeding the harvested culm from the pre-processing unit to the feed chain of the threshing unit in a combine, etc., change the position of the root of the feed chain by the feed chain with the handling depth adjustment device (for long culms, the amount of root protruding from the holding position is changed. In the case of large and short culms, the amount of protrusion is made small) so that the handling depth is always constant, so that a good shedding action can be performed without leaving unhandled portions. However, the threshed culm is fed to the binding machine side with a different amount of protrusion on the stock side due to the handling depth control. The setting position of the alignment device also needs to be adjusted accordingly.

Therefore, the present invention can set the movable width of the stocking device to be large without exerting excessive force on the transmission system, and can greatly enhance the adaptability to the length of the culm length. In other words, it is an object of the present invention to provide a stocking source aligning device of a binding device that can easily perform an adjusting operation by only moving the stocking source aligning device.
