Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain tank having an inlet for taking in grains collected from a threshing device at an upper portion thereof, and a mounting structure of a paddy sensor for detecting a height of accumulation of the grains in the grain tank. Regarding

[0002]

2. Description of the Related Art Conventionally, since a paddy sensor for detecting the height of accumulation of grains in a grain tank is for detecting a preset full state of the grain tank,
It was fixed at a predetermined upper position in the Glen tank. By the way, when the paddy sensor detects the preset full state of the Glen tank, it activates an alarm device such as a buzzer or a lamp in response to the detection to confirm that the Glen tank has reached the preset full state. It is configured to notify the person. On the other hand, the worker starts to discharge the grains in the grain tank based on this notification.

[0003]

However, in the above-mentioned prior art, since the paddy sensor is fixed to a predetermined upper position in the grain tank, the accumulation of grains in the grain tank detected by the paddy sensor is detected. Since it is not possible to change the height, "I want to delay the detection timing of the full state by the paddy sensor so that the grain discharge work can be started when more grains are packed in the Glen tank." In addition, it was not possible to meet the worker's request such as "I want to accelerate the detection timing of the full state by the paddy sensor so that the work of discharging the grain can be started at an earlier stage".

An object of the present invention is to make it possible to easily change the height of accumulation of grains in the grain tank detected by the paddy sensor so that the timing of detection of the full state of the grains by the paddy sensor can be requested by the operator. It is to be able to easily adjust the detection timing according to the above.

[0005]

In order to achieve the above-mentioned object, in the invention according to claim 1 of the present invention, a grain tank having an inlet for taking in grains collected from a threshing device is provided in the grain tank. A paddy sensor for detecting the pile height of the grains in the grain tank was provided so that the position could be adjusted laterally.

According to the invention described in claim 1, since the grain tank is provided with an intake port for taking in the grains collected from the threshing device in the upper portion thereof, the grains from the intake port are provided inside the grain tank. Grains will be accumulated in a state of being heavier at the point where more drops occur. From this phenomenon,
When the position of the paddy sensor is adjusted in the lateral direction on the side closer to the point where a large number of grains fall from the intake (the apex of the accumulated grains), the paddy sensor will detect the inside of the grain tank as it gets closer to that point. The sedimentation height of the grain in is low. Also,
When the paddy sensor is adjusted in the lateral direction on the side away from the point where a large number of grains fall from the intake, the more the paddy sensor is located from that point, the more the grain height in the grain tank is detected in the grain tank. Becomes higher. That is, by adjusting the position of the paddy sensor in the lateral direction, it is possible to change the deposition height of the grain detected by the paddy sensor in the grain tank, and the operator can set the detection timing of the full state of the grain by the paddy sensor. The detection timing can be adjusted accordingly.

Incidentally, it is conceivable that the height of grain accumulation in the grain tank detected by the grain sensor can be changed by adjusting the position of the grain sensor in the vertical direction. The inspection port for maintenance, such as checking the degree of grain accumulation, is installed at the top of the Glen tank, so the lower the grain accumulation height detected by the paddy sensor, the more accessible the paddy sensor. This makes it difficult to adjust the position of the paddy sensor in an unreasonable posture. In this respect, in the invention according to claim 1, the height of accumulation of grains in the grain tank detected by the paddy sensor can be changed by laterally adjusting the position of the paddy sensor in the upper position near the inspection port. From
When changing the pile height of grain detected by the paddy sensor, it becomes difficult to reach the paddy sensor from the inspection port equipped on the upper part of the grain tank, and the position adjustment work of the paddy sensor must be done in an unreasonable posture. There is no inconvenience of having to do it.

Therefore, since the height of accumulation of grains in the grain tank detected by the paddy sensor can be easily changed by adjusting the position of the paddy sensor in the lateral direction, the timing of detecting the full state of the grain by the paddy sensor can be It has become possible to easily adjust the detection timing according to the operator's request.

According to the second aspect of the present invention,
In the invention described in claim 1, the position of the paddy sensor in the lateral direction is adjusted by sliding the paddy sensor.

According to the second aspect of the invention, the lateral position of the paddy sensor is adjusted by sliding the paddy sensor, so that the lateral position of the paddy sensor is continuously adjusted. Since this can be done, it becomes possible to continuously change the deposition height of the grain in the grain tank detected by the paddy sensor. That is, it becomes possible to finely adjust the detection timing of the grain full state by the paddy sensor. Further, since the lateral position of the paddy sensor can be adjusted by sliding, the lateral position of the paddy sensor can be adjusted in the lateral direction as compared with the case where the padding sensor is replaced. Since there is no need to attach and detach the paddy sensor for each position adjustment, the lateral position adjustment operation of the paddy sensor becomes easy.

Therefore, it becomes possible to more easily and accurately adjust the detection timing of the full state of the grain by the paddy sensor to the detection timing according to the operator's request.

According to the third aspect of the present invention,
In the invention according to claim 1, the position of the paddy sensor in the lateral direction is adjusted by replacing the paddy sensor.

According to the third aspect of the present invention, the mechanism for sliding the paddy sensor is compared to the case where the padding sensor is laterally adjusted to slide the paddy sensor. Since it is not necessary to provide the like, the configuration can be simplified and the manufacturing cost can be reduced.

Therefore, it is possible to easily adjust the detection timing of the grain full state by the paddy sensor to the detection timing according to the operator's request, while simplifying the configuration and reducing the manufacturing cost. .
