Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a running safety device for a combine harvester, which can be used when the combine harvester is running on a vehicle body with grain stored in a grain tank.

PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION In a combine harvester equipped with a grain tank for storing harvested grains, when the grains are stored in the grain tank, the center of gravity of the vehicle body becomes higher; If this grain tank is provided on one side of the vehicle body, the load distribution on the left and right sides of the vehicle body is biased to one side, so that the shared loads received by the left and right traveling devices differ.

During combine harvesting operations, when the appropriate amount of grain is harvested and stored in a grain tank, it is transferred to a transport vehicle parked on a farm road, etc. When the distance between the harvester and the transport vehicle is large, in order to improve work efficiency, the auxiliary gear of the traveling device is switched to the high speed side and the combine is run from a low working speed to a high road speed. There are cases.

The field is hard and soft in some places, the grain in the grain tank raises the center of gravity of the vehicle, and the load shared by the left and right traveling devices differs greatly, so it is difficult to drive at high-speed road speeds. This can cause the vehicle to tilt when turning, which can be dangerous.

Therefore, the present invention is designed to operate a buzzer or the like to warn the operator when the vehicle body attempts to run at a high speed when the grain tank contains more than a predetermined amount of grains, so that the operator can drive safely. This is what I am trying to do.

Means for Solving the Problems The present invention provides a grain sensor (
2) is provided, and when the grain sensor (2) detects a predetermined amount or more of grains and the traveling device (3) is operated to shift to a high speed side, the alarm device (4) is activated. This is the configuration of a travel safety device for combine harvesters.

Functions and Effects of the Invention During the combine harvester operation, the traveling device (3) is sub-shifted to a low speed side, and reaping and threshing is performed while traveling at the working speed.

When the appropriate amount of grain is stored in the grain tank (11),
The combine harvester operation will be stopped in order to transfer the grain to a transport vehicle parked on a farm road. A grain sensor (2) indicates that the grain tank (1) has contained more than a predetermined amount of grains.
is detected. When this grain sensor (2) detects a predetermined amount or more of grains, when the traveling device (3) is operated to the high speed side in order to move the combine harvester, an alarm device (
4) is activated to alert the operator.

This warning allows the operator to recognize that more than a predetermined amount of grain has been stored in the grain tank (1), so the operator operates the sub-shift of the traveling device (3) to the low speed side and starts the combine at a working speed in the low speed range. can be driven safely.

Example: In turning, the combine harvester uses the left and right traveling device (3)
A threshing device (6) is mounted on a chassis (5) having a wheel, and a reaping device (7) is provided at the front of the threshing device (6). Grain tank (1)
is provided next to the threshing device (6) (1 [!), and a driver's seat (8) is provided at the front of one side of the chassis (5) in front of this grain tank (1).

A running collar (10) for changing the speed of a continuously variable transmission that continuously changes the left and right running devices (3) forward and backward from the prime mover side is disposed on a control platform (9) on the side of the cockpit (8); This traveling device (
3) is provided with a sub-shift lever (11) for operating the sub-shift between light and low. When the sub-shift lever (Ill) is operated to shift the sub-shift lever (Ill) to the low-speed side and the travel lever (1ω) is shifted to the forward/reverse side, the left/right traveling device (3) is continuously variable to forward/backward at a working speed in the low speed range, and When the sub-shift lever (Ill) is operated to shift to a high speed side, the left/right travel device (3) is configured to be continuously variable forward/backward at road speeds in the high-speed range. If you operate the sub-shift to the side, it will come into contact with the
An auxiliary speed change switch Q2) is provided.

The grain tank (1) is configured to store grains that have been threshed and milled by the threshing device (6), and rotates in a direction to hoist and discharge the stored grains to the outside of the machine. There are 13 adjustable drainage augers.

A grain sensor (2) is provided to detect when the amount of grain in the grain tank (1) exceeds a predetermined amount. The grain sensor (2) includes a full sensor (2B) located at a position that detects when the grain tank (1) is full, and a full sensor (2B) located below the grain tank (1). Lower sensor (2A) that detects when approximately half of the grains in the container are full.
It is composed of.

Although this lower sensor (2A) is positioned at a position where it detects approximately half the amount when it is full when it is turned, it is not limited to this.

These full sensor (2B) and lower sensor (2A) are configured to be turned on by pressing the grains contained therein.

Figure 2 is an electrical circuit diagram, in which the lower sensor (2A) and the sub-shift switch (1) are connected in series, and when both the lower sensor (2A) and the sub-shift switch (1) are turned on, a buzzer (14J) is activated. The circuit configuration is such that power is supplied to the monitor lamp (one monitor lamp) at the same time.

Also, when the full sensor (2B) turns on, the buzzer (1
4) and the full monitor lamp (16) are energized. (m is the main switch. Alarm device (
4) consists of these buzzer Q41, one monitor lamp, and one full monitor lamp,
It is provided on the cockpit (IEI) in front of the cockpit (8).

Power is transmitted to each part, and when the sub-shift lever (11) is operated to the low speed side and the travel lever (11) is operated to the forward side,
The power is transmitted to the traveling device (3), and the combine runs at a working speed, and the harvesting and threshing work of the husk is performed.

In the combine operation, the harvested and threshed grains are fried and stored in a grain tank (1). When the number of stored grains increases, the lower sensor (2A) turns ON. This lower sensor (2A) is installed inside the grain tank (1).
When the grain is stored beyond the position where is turned ON, the combine operation is stopped and the stored grain is discharged to the transport vehicle parked on the farm road.
When you switch to the high speed side, the sub-shift switch is turned on,
The buzzer 04 is activated and the monitor lamp (19) lights up to warn the operator. This warning allows the user to recognize that the grain tank (1) has contained more than a predetermined amount of grains, so the sub-shift lever ( Since the lυ is returned to the low speed side and the combine is run at a working speed in the low speed range, it can be run safely.

If the grains in the grain tank (11) are less than the specified amount,
The alarm system (
4) is not activated, so in this case, even if the combine is run at a high road speed, the vehicle body will not tilt when turning, and the combine can be driven safely.

When the grain tank (1) is full, the full sensor (2B) is turned on, the buzzer 041 is activated, and the full monitor lamp (old) lights up to warn the operator. Since it can be recognized by the lighting that the grain tank +1) is full of grains, the combine harvester can be safely driven at a working speed in the low speed range.
