[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a failure alarm device in a combine harvester for cutting and threshing a grain culm.

[0002]

2. Description of the Related Art Conventionally, a sensor for detecting an abnormality is attached to a grain tank, a straw conveying device, a pretreatment device, or another working section, and a control device for stopping an engine when the sensor is in a sensing state. Combines having are already known.

[0003]

In the known alarm monitor of the combine, since the monitors are distributed in various places, when the engine stops, it is difficult to understand the cause of the stop. In addition, it was necessary to attach precautionary notes when the monitor was activated to various places. In addition, when the engine stops, the traveling device cannot be driven, so that the aircraft cannot escape from the field, making repair difficult.

[0004]

Means for Solving the Problems The present invention is, grain tank 6, straw discharge conveying device, or abnormal was attached a sensor for sensing the pretreatment apparatus 10 other work unit, the sensing state before Symbol detector to become the in combine with a control device to stop the engine, as well as a collection place multiple monitors to display the detection result of the sensor to the operation panel 3, the operation
Work equipment clutch lever and control device for intermittent power of department
And stop the engine by turning off the work equipment clutch lever
The above-mentioned problem was solved by linking so that the control was released .

[0005]

[Action] When the engine is started, each clutch is engaged, and each part is driven and advanced, the pretreatment device cuts the culm and transports it to the threshing device, and the threshing device performs threshing and sorting. In addition, the grain is carried out, and the straw is carried out by the straw conveying device, and the straw processing is appropriately performed. And
During the above work, sensors attached to various working units,
For example, the engine stops when various sensors, such as a clogging sensor attached to the pretreatment device or the waste conveying device and a clogging sensor attached thereto or an overflow sensor attached to the grain tank, are in a sensing state. At this time, no matter which sensor goes into the sensing state, the monitors are arranged in a collective state on the operation panel, so it is possible to immediately and clearly determine the cause of the stop by visually recognizing one place. Therefore, the cause of the stop can be promptly and accurately dealt with in accordance with the precautionary statement in the vicinity. Also, depending on the cause of the stop, the work machine clutch lever 24
Since it becomes possible to operate the engine by turning off the , the aircraft can be moved to perform appropriate repairs.

Is attached.

The operating panel 3 is disposed in front of the driver's seat 5 and, when tilted forward and backward, the pre-processing device moves up and down, and when tilted right and left, an operating lever for intermittently connecting and disconnecting the tilted side clutch. 15, a running direction automatic control monitor 16, a horizontal control monitor 17, a sorting automatic control monitor 18, and a handling depth automatic control monitor 20 are arranged as a group, and are connected to the overflow detector 12 in order from the left in front thereof. Overflow monitor 21, waste clog monitor 22 connected to straw clog sensor 13, and pre-processing clog monitor 23 connected to pre-processing clog sensor 11
Are arranged close to one place, and a work machine (threshing) clutch lever 24 provided with a work machine clutch switch 24c is provided on a lever panel 24a provided on the threshing device 2 side of the driver's seat 5.

The pretreatment clogging sensor 11, the overflow sensor 12, the waste clogging sensor 13, the auger sensor attached to the discharge port of the auger 25 connected to the discharge part of the grain tank 6, the working machine clutch Switch 24
c , the result of sensing the engine stop switch is input to a control device 26 comprising a microcomputer, and the output of a fuel cut relay 27 of the control device 26 is connected to an engine solenoid 28 so as to be transmitted to the engine solenoid 28; Clogging sensor 11, overflow sensor 12, and straw clogging device 1
When 3 is in the detection state (ON), the relay 27 is turned off, whereby the engine solenoid 28 is also turned off, the fuel is cut, and the engine stops. In addition, the overflow detector 12 controls the overflow monitor 21 to
The pre-processing clogging sensor 11 is connected to a pre-processing clogging monitor 23, and the detection value of the waste clogging detector 13 is input to a control device, and the result of arithmetic processing is used as a result of the waste clogging monitor 22.
And is displayed on each monitor.

The pre-processing clogging sensor 11, overflow sensor 12, and waste clogging sensor 13 are connected to buzzers (not shown), and the buzzer of the overflow sensor 12 operates intermittently. The buzzers of the waste clogging sensor 13 and the pre-processing clogging sensor 11 are continuously operated, and when any of the monitors 21, 22, 23 is turned on, they are arranged in one place. Therefore, the failure location can be identified at a glance, and the maintenance of the failure location can be performed immediately. At that time, if it is necessary to escape from the field the airframe by the fault location can operate off the work machine clutch lever 24, the working machine clutch switch 24c detects that the clutch OFF, start the engine Start the engine and move the aircraft to a location where repair work is easier.
