Description

[Detailed description of the invention] The present invention consists of a conveyance chain that pivotally supports the stem culm locking pawl in a freely undulating manner, a drive sprocket and an idling sprocket that wind and drive the conveyance chain horizontally, and the conveyor chain's The present invention relates to a stem culm conveying device that includes a rail for guiding movement, a guide for keeping the stem culm locking claw in an upright position at a conveying position, and a conveying case that covers the entirety of these.

Conventionally, the idling sprocket, chain rail, and pawl raising guide are supported by a frame connected to the machine frame, and also connected from the machine frame or the frame to prevent debris from adhering to the sprocket or conveyor chain. A supporting transport case is provided to cover the entire transport device from above and below.

However, with this structure, since a frame and a case are provided, the overall weight tends to be large, and there is a risk that straw debris may enter and accumulate inside the case and interfere with the rotation of the chain. .

The present invention was made keeping in mind the above actual situation,
In the stem culm conveyance device described at the beginning of the detailed description, the conveyance case is supported by the cylindrical case that supports the drive shaft of the drive sprocket, and the idle sprocket, the chain rail, and the claw erecting The present invention is characterized in that the guides are directly suspended from the lower surface of the transport case to form a transport device with an open bottom, and the following effects can be obtained.

In other words, since the transport case itself is used as a support frame for each of the above-mentioned components, the overall structure can be made lighter, and the upper part is covered with the transport case to prevent straw debris from adhering. However, since the lower part of the case is open, a large amount of straw waste does not accumulate inside the case, and the chain can be rotated smoothly for a long period of time. Because the lower part of the transport case is open, it is possible to easily inspect and adjust various parts such as the chain, and the interaction of the above-mentioned effects makes it extremely convenient in practice. A stem culm conveying device was obtained.

Embodiments of the present invention will be described in detail below based on the drawings.

The figure shows the stem culm conveying device installed on the combine.
Driving sprocket 1. The stem culm locking pawl 5 and the two free-rotating sprockets 2 and 3 and the tension sprocket 4
A conveyor chain 6, which is pivoted at appropriate intervals, is wound horizontally.

As the chain 6 is laterally driven, the pawl 5
... is configured to hold and convey the stem culm while raising and lowering it by the action of its base abutting against the nail raising guides 12, 13 and the raising roller 16 (see FIG. 2).

As shown in FIG. 2, the drive sprocket 1 is connected to an auxiliary transmission case 8 that is connected to a horizontally mounted reaping mission case 7 that branches and transmits power to a pulling device, an auxiliary conveyance device, etc.
It is fixed to a drive shaft 9 supported by.

The drive shaft 9 extends upward in order to drive another transport device (not shown) which is arranged overlappingly above the transport device, and covers the upwardly extending portion of the drive shaft 9. A transport case 11 that covers the entire transport chain 6 from above is connected and supported by the cylindrical case 10 .

The conveyance case 11 is formed in a shape with its lower part open, and as shown in FIGS. 2 to 5, the two idling sprockets 2 and 3, the tension sprocket 4, The guide for raising both claws 1
Two chain rails 14 and 15 are supported which receive and guide the chain 6 when the chain 6 is in the upright position.
