Description

[Detailed Description of the Invention] [Industrial Application Field] The great invention is to provide a grain fullness sensor inside a discharge port for dropping grains into a grain bag, and to provide a grain fullness sensor above this fullness sensor. The present invention relates to a grain bagging device which is provided with a shutter mechanism for shutting off the supply of grains.

[Conventional technology]

This type of grain bagging device supplies grain by pushing a grain outlet at the lower end of the hopper into the opening of a grain bag suspended from a pair of support rods, and The full sensor installed on the side of the grain bag indicates that the grain bag is full.
Based on the detection result, the shutter mechanism provided above the sensor is automatically closed to supply grains! - It is known that the force is configured to stop (Japanese Patent Application Laid-Open No. 61-930368 + Public FA).

However, with the structure of this reference, the grains are simply poured into the grain bag, so there are many gaps between the grains, and even if the grain bag is full, the grains will be trapped during transportation. The vibrations caused the grains inside to become tightly packed, creating a space at the top of the grain bag, making it impossible to fully utilize the bag's capacity.

In order to solve this problem, the grain bag is shaken by a tensioning device while the grain is being supplied from the outlet to the grain bag, and the grain is tightly packed inside the grain bag. I'm also considering filling it with grains.

[Problems to be solved by the invention in 1)] However, in the above-mentioned method, in order to avoid being shaken for a long period of time, the bag is packed more densely than necessary, and the bag swells greatly and cannot be secured by the zipper. There is a possibility that the closing operation will not be possible.

In addition, since the grain bags are hard and swell, they become heavy and difficult to handle, and tend to become unstable when stacked. Furthermore, since the rocking device tf'F- is continuously moved, the tension is transmitted to the fuselage body, resulting in a problem that the comfort in the driving section is deteriorated.

Therefore, the great invention was made in view of this shortcoming, and by rationally modifying the grain bagging device, the capacity of the grain bag could be increased. Is it inconvenient to handle wasteful and unnecessary power? Is it possible to fill grain bags with grains without causing any turbidity? The purpose is

〔problem? Means for Solving] To achieve the above-mentioned objects, the ninth feature of the present invention is to provide a oscillating device for shaking the grain bag, and also to cause the oscillating device to oscillate upon the first detection of the fullness sensor. This? Activate it, Tatsugai-so α
Is there a full sensor and a shutter mechanism so that the shutter mechanism closes and operates when the full state is detected after the operation? They are linked in certain ways, and their actions and effects are as follows.

[For production]

In other words, when the grains are dropped from the discharge port into the first opening of the grain bag and the two sides of the grains reach the full sensor provided inside the discharge port, the full sensor or The grain bag is detected and the vibration device is activated in response to the detection signal 8 to shake the grain bag. Then, due to the vibration, the upper surface of the V-grain bag and the grains in the discharge port lowers, and the full sensor becomes 4Vc, which is not detected. However, even though the grains gradually become densely packed and the upper surface of the grains lowers due to parking in the furnace, the inside of the discharge port is narrow and Vζζ is being supplied with powder. The top of the grain rises and becomes 7i again! Is the i cup sensor reached and the full sensor detects full for the second time? conduct. At the same time, the shutter mechanism is automatically closed and the grain supply is stopped.

〔Effect of the invention〕

According to the invention, the capacity of the grain bag can be increased by temporarily shaking the grain bag to make the grains filled inside the bag to an appropriate density. It is possible to avoid wasting effort and inconvenience in handling such as zipper closing operations, continuous shooting, and stacking.

The grain bagging device is used for grain bagging equipment that has a structure such as a combine harvester that continuously feeds grain into a hopper and cools it.F16, from the start of bagging, the full grain bag (5) is released. It is designed so that the operation is carried out automatically until the operation is completed.
