Description

[Detailed description of the device]

[0001]

[Technical field to which the invention belongs]

 The present invention is composed of a grain-culm pinching and transferring device of a thresher, and more specifically, a feeder chain and a sandwiching rail arranged along a front side portion (outer side portion of the mouth) of the thresher. The present invention relates to a grain culm sandwiching and transporting device which clamps a culm root of a grain culm to be threshed and laterally transports it.

[0002]

[Prior art]

 Some of the conventional grain and stalk pinching and transferring devices are configured such that either one of the feed chain or the pinching rail can be changed from the normal pinching action position to the non-pinching action position (for example, , JP-B-58-25793 and JP-A-57-208922).

[0003]

[Problems to be solved by the device]

 In the conventional type, a part of the feed chain or the pinch rail can be retracted and separated from the other side (pinch rail or feed chain). Since it was not possible to fully open the front side of the handling room by separating it, there was the drawback that cleaning and inspection maintenance inside the handling room would not be so easy.

[0004]

[Means for Solving the Problems]

 The present invention is a position where the front side of the handling chamber is largely opened from the clamping action position for both the feed chain and the clamping rail that clamp and traverse the culm side of the grain culm to be threshed in the handling chamber. It will be installed so that it can be relocated. In this way, the retreat of both the feed chain and the pinch rail greatly opens the front part of the handling room, which facilitates cleaning and inspection of the handling room.

[0005]

[Embodiment of the invention]

 In the grain culm pinching and transferring device of the present invention, both the feed chain and the pinching rails arranged along the front side of the handling chamber are moved separately from the pinching position (normal position) to the retracted position. It is provided so that it can be rotated and moved to (the position where the front side of the handling room is opened).

The pinching rail is provided so that it can be retracted and held in a direction in which the pinching interval between the pinch and the feed chain is widened, and after the pinching rail is retracted, the field rail is retracted. It is preferable to configure the dotiene to be regressed.

[0007] In addition to providing both the feed chain and the pinch rail so as to be able to retreat from the pinching position to a position where the front side of the handling chamber is largely opened, the front side of the handling chamber is also provided. If the handling room side plate is installed so that it can be opened to open the handling room, the handling room will be opened further, and cleaning and inspection / maintenance of the handling room will be easier.

[0008] Further, both the feed chain and the pinch rail are provided so as to be able to retreat from the pinching position to a position where the front side of the handling chamber is largely opened, and the handling chamber at the front side of the handling chamber is provided. If the side plate is provided so that it can be opened in the handling chamber open state, the feed chain and the handling chamber side plate are retracted if the feeding chain is moved to the retracted position together with the opening of the handling chamber side plate. The movement to the position and vice versa is simplified.
