Description

[Detailed explanation of the invention] Conventional combine harvesters with a grain tank mounted on the machine transport the grain in the grain tank in bulk on a transport vehicle such as a truck or trailer. It was not possible to determine the amount of grain.

Therefore, it is not possible to grasp the yield of each field or designated area, which is inconvenient for rational business management.In addition, in the case of wage harvesting, the amount of work is not clear, leading to conflicts between the labor harvester and the client. A problem occurred.

The present invention aims to improve the above-mentioned drawbacks or obstacles.
The aim is to measure the amount of grain in the grain tank extremely easily and accurately, but when loading the grain in the grain tank onto a transport vehicle, the machine is pulled along the road, so the traveling device of the combine is used. The grain tank may run over a ridge, or the machine may tilt due to unevenness in the field.In such cases, using a system that supports one side of the grain tank in a rotatable manner will prevent distortion in the grain tank. As a result, the contact portion of the grain tank with respect to the scale becomes misaligned, making it impossible to carry out accurate measurement and causing problems such as damage to the scale.

The purpose of the present invention is to improve the above-mentioned drawbacks, and is to provide a combine harvester with a grain tank mounted on the machine base, in which the lower part of one side of the grain tank can be tilted horizontally on the machine base. The base of the support member is pivotally supported on the lower pivot side of the grain tank so as to be able to swing vertically, and the tip of the support member is extended toward the scale. It is characterized in that it is configured such that the grain tank is brought out and connected to the grain tank, and the lower part of the grain tank is placed on the support member for weighing.

The grain tank 5 tilts downward and rides on the support member 50, and is detected by the load cell 52, and the detected value is input to the display 54 provided on the upper front surface of the grain tank 5 and digitally displayed.

The load cell 52 is a tension type, but if the measuring device is a compression type load cell, a measuring device 52' is provided on the machine base 2 as shown by dotted lines in FIGS. 5 and 6,
The lower surface of the support member 50 is brought into contact with the support member 50. Also in this case, during the operation, the grain tank 5 is supported by a support device so that the pipe 53 is slightly spaced from the measuring device 52'.

In the above-mentioned combine harvester, the grains lifted by the grain lifting cylinder 11 of the threshing device 1 are put into the grain tank 5, and when the grain tank 5 is full, the machine is moved along the road and supported. When the operating rod 36 of the device is pushed down and released, the grain tank 5 is tilted toward the threshing device 1 side, and at the same time the pipe 53 is moved toward the support member 50.

Since the load is applied to 2, 52', the load cell 52, 5
2' senses the weight of the grain and displays it on the display 54 so that the operator can follow the grain weight.

At that time, even if the traveling device rides on a ridge and the machine body tilts, the grain tank 5 is distorted, and the pipe 53 shifts back and forth, this is absorbed between the pipe 53 and the support member 50. It is possible to prevent inaccurate measurement and damage to the load cell.

Next, the telescoping cylinder at the bent portion of the grain thrower 10 is operated to make the grain lifting cylinder 10c continuous, and the telescoping cylinder ₁₃ attached to the base cylinder 101 is activated.
After operating the discharge cylinder ₁₀₁ to face the loading platform of a truck parked on the road, the clutch pulley 25 is lowered to tension the belt 26, and the transfer spiral 9 and the flip-up vane 10b are rotated. When the shutter 39 is opened using the operating lever 45 after the grains have been allowed to dry, the grains are fried and thrown into the loading platform of the truck.

After the grain has been input, the shutter 39 is closed, the transfer spiral 9 and the flip-up blade 10b are stopped, and the fried grain thrower 10 is placed in the storage position shown in FIG.

A transmission mechanism between the threshing device 1 and the grain tank 5, for example, a transmission mechanism that drives the first transfer spiral, the second transfer spiral, or a winnow of the threshing device 1, and the opening/closing window of the threshing device 1 are controlled. When opening the sorting device for maintenance and inspection, normally the grains in the grain tank 5 are discharged and then the handle 5 at the top of the grain tank 5 is opened.

The present invention provides a combine harvester with a grain tank mounted on the machine base as described above, in which the lower part of one side of the grain tank is pivotally supported on the machine base so that it can be tilted laterally, and a measuring device is disposed on the other side. The base of a support member is pivotally supported on the lower pivot side of the grain tank so as to be able to swing up and down, and the tip of the support member is extended to the measuring instrument side and connected to the grain tank. Since the grain tank is configured to be weighed by placing the lower part on the support member, the weight of the grains in the grain tank, which is rotatably supported on one side by the machine base, can be easily measured by the weighing device on the other side. Moreover, even if the aircraft is tilted and the grain tank is twisted, the weight of the grain tank will be applied to the scale via the support member, making it possible to measure accurately. It is possible to carry out weighing and to prevent damage to the measuring instrument.
