DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor for driving a traveling device or the like by rotating an emergency stop means,
The present invention relates to an emergency stop device for stopping and controlling both a feed chain motor for rotatingly driving a feed chain for transferring a harvested culm by a control means.

[0002]

2. Description of the Related Art For example, when threshing a harvested culm obtained by hand-cutting a ridge, the traveling device of the combine is run or stopped, and the harvested culm is supplied to a threshing machine. The threshing is carried out while being transported by the feed chain of the threshing machine. If an abnormal situation occurs during this threshing operation, for example, when a foreign object (worker's clothes) is caught in the feed chain, the emergency stop means is stopped, and the stop device is operated by the stop operation if the traveling apparatus is running. And the threshing machine is stopped. With the stop of the threshing machine, the feed chain automatically stops.

[0003]

Even if an abnormal situation occurs during the threshing operation and the emergency stop means is stopped to stop the threshing machine, the threshing machine rotates by a conventional method and does not stop immediately. As a result, the feed chain is not immediately stopped, and the emergency stop does not occur. However, the present invention is intended to solve this problem.

[0004]

For this purpose, the present invention provides an emergency stop means 24 for urgently stopping the motor 16 for rotating and driving the traveling device 7 and the like, and a feed chain of the threshing machine 2 for transferring the harvested grain culm. In a combine provided with a feed chain motor 19 for rotatingly driving the motor 8, a control means 27 for controlling both the motor 16 and the feed chain motor 19 based on the emergency stop operation of the emergency stop means 24 is provided. An emergency stop device, such as a combine, is provided.

[0005]

When the harvested culm obtained by hand-cutting the edge of the limb is threshed by a combine, the traveling device 7 of the combine is run or stopped, and the harvested culm is supplied to the threshing machine 2. The threshing is carried out while being transported by the feed chain 8 of the threshing machine 2. If an abnormal situation occurs during this threshing operation, for example, when a foreign matter (operator's clothes) is caught in the feed chain 8, the emergency stop means 24 is stopped,
As a result of this stop operation, the prime mover 16 is immediately stopped during traveling, the traveling device 7 is stopped, the feed chain motor 19 of the threshing machine 2 is immediately stopped, and the feed chain 8 is also immediately stopped at the same time. To deal with the abnormal situation that has occurred.

[0006]

According to the present invention, when an abnormal situation occurs during the threshing operation and the emergency stop means 24 is stopped, if the vehicle is traveling, the prime mover 16 is immediately stopped and the traveling device 7 is stopped.
Irrespective of the rotation of the threshing machine 2 due to the customary operation, the feed chain motor 19 is immediately stopped and the feed chain 8 is also immediately stopped, so that an abnormal situation can be dealt with immediately.
