Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stem and culm transporting device used in a harvester such as a combine, and more particularly, to a support rod of a stalk and stalk transporting holding rail slidable toward and away from an endless rotation zone for transporting stalks and stalks. A spring attached to the holder and biasing the holding rail toward the endless rotation band is interposed between the holder and the locking part of the support rod to hold the holding rail away from the endless rotation band. The present invention relates to a stem-culm transporting device provided with an action releasing means.

[0002]

[Prior art]

 Conventionally, as a stalk-carrying device provided with a gripping action releasing means, a holder 31 is attached to a curved supporting rod 30 and a supporting rod 32 is slidably urged by a coil spring 33 as shown in FIG. The holding rail 34 is attached to the holder 31 by means of the coil spring 33, and the holding rail 34 is pressed and biased toward the endless rotation belt 35 by the coil spring 33. The endless rotation belt 35 and the holding rail 34 cooperate to hold and convey the stems. The bending support rod 30 is bent at the waist so as to form a holding action releasing means for separating the holding rail 34 from the endless rotation belt 35 when the stalk is clogged between the endless rotation belt 35 and the holding rail 34. There is a structure in which the bending support rod 30 is fixed by a tightening bolt 36 at the waist bending portion to maintain the gripping rail 34 in the transport operation position.

[0003]

[Problems to be solved by the device]

 However, the external force that tries to extend the curved support rod acts on the gripping rail during the transportation of the stem culm, so there is a risk that the stalk gripping force of the endless rotation band and the gripping rail will be weakened due to the loosening of the tightening bolt. Yes, there was room for improvement in terms of prevention of gripping and transport problems. An object of the present invention is to surely prevent a failure in carrying and holding due to the holding action releasing means.

[0004]

[Means for Solving the Problems] A characteristic configuration of the first invention is that a support rod of a holding rail for transporting stalks is attached to a holder slidably in an approaching and separating direction with respect to an endless rotation zone for transporting stalks. A gripping action releasing means for separating the holding rail from the endless rotation band is provided by interposing a spring for urging the holding rail in the direction of approaching the endless rotation band between the holder and the engaging portion of the support rod. In the provided stem-and-culm transfer device, in order to form the holding action releasing means, the spring is formed of a leaf spring and is attached to the holder so that the position of the support rod can be changed between the engagement position and the disengagement position with respect to the engagement part. Especially.

Further, the second aspect of the invention is characterized in that the support rod of the stalk-carrying holding rail is slidably attached to the holder in the direction of approaching and separating from the stalk-carrying endless rotation band, and the holding rail is rotated endlessly. A stalk-carrying device in which a spring for urging in the direction of approaching the movement zone is interposed between the holder and the locking portion of the support rod, and a holding action releasing means for separating the holding rail from the endless rotation zone is provided. In order to form the holding action releasing means, the spring is formed by a leaf spring and attached to the holder, and the engaging portion of the support rod is formed by an engaging pin so as to be located at an engaging position and a disengaging position with respect to the leaf spring. It was installed on the support rod so that it could be changed.

[0006]

[Action]

 According to the structure of the first invention, by changing the mounting position of the leaf spring with respect to the holder and engaging and disengaging it with the engaging portion of the support rod, the holding rail is kept in the holding action position and separated from the endless rotating body. The gripping rail is maintained in the gripping position by the locking action of the leaf springs during transportation of the stem culm, so that the endless swivel band and the gripping rail ensure sufficient gripping of the stem culm. Therefore, it is possible to reliably prevent the defective carrying and carrying due to the holding action releasing means.

Further, according to the configuration of the second invention, by changing the mounting position of the locking pin with respect to the support rod and engaging with and disengaging from the leaf spring, the holding rail is maintained in the holding action position and the endless rotation. It is switched to a state in which it is separated from the moving body, and when the stalks are transported, the holding pin is held in the holding position by the locking action of the locking pin against the leaf spring, so that the endless rotation band and the holding rail can hold the stalks sufficiently. It is possible to reliably secure the force, and it is possible to reliably prevent a defective carrying and carrying due to the holding action releasing means.

[0008]

[Effect of device]

 As a result, when the culm is jammed between the endless swivel belt and the holding rail, the gripping rail can be easily separated from the endless swivel belt to easily clear the clogging, but the gripping action for removing the gripping action can be achieved. It is now possible to provide a much superior stalk and culm transport device that can reliably prevent defective transport and prevent pinching and transport problems.
