Description

[Detailed Description of the Invention] This invention provides a grain bagging device, more specifically, a support rod for suspending the opening of the bag and a pedestal for receiving the bottom of the bag are arranged below the grain tank. Related to bagging equipment.

Generally, in a combine harvester, the grain culm cut by the reaping part is threshed by the threshing part, and the threshed grains are supplied to a grain tank provided on the side of the threshing part, and the grains are fed from the tank. It's like packing it into a bag of grains.

Therefore, the grain bagging operation is carried out by suspending both upper sides of the grain bag from support rods provided below the tank.
The opening of the bag faces the supply port of the tank, and the bottom of the bag is placed on a pedestal below the support rod.

By the way, the work of the combine harvester is often carried out by one operator, for example, the operation of the combine and the bagging work are carried out by one operator. After placing the grain bag supported by the support rod at the supply port of the grain tank in order to take it out, the operator returns to the driver's seat and operates the combine harvester, and the grain bagging process is automatically carried out. I'm doing it as if I were doing it.

However, during the grain bagging operation as described above, it is not possible to effectively fill the grain bag with a predetermined amount of grain by simply charging the grain from the tank into the grain bag. Moreover, if the bottom of the grain bag is bent, it is not possible to fill the grain bag with a predetermined amount of grain.

Conventionally, as shown in Japanese Utility Model Application No. 52-8086, for example, a vibrating body is provided on a pedestal that receives the bottom of the grain bag, and the vibrating body pushes up the bottom of the bag to vibrate it. A bagging device was proposed in which grains were forcibly filled inside the bag, but in such a bagging device, unless the amplitude of the vibrating body was increased, the vibration of the vibrating body would not be transmitted to the top of the bag. However, a reliable packaging effect cannot be expected.

However, when increasing the amplitude of the vibrating body in order to apply the vibration to the upper part of the bag, there is a risk of giving a large shock to the support rod and causing damage, and furthermore, the bottom of the grain bag may be bent. In such cases, it was no longer possible to cope with the situation, and it was no longer possible to bag grain reliably and effectively. Furthermore, in the bagging device, it is necessary to push up the bottom of the grain bag using a vibrating body, which means that it is necessary to push up the entire heavy bag containing grains, resulting in power loss. It's big.

However, in order to solve the various problems mentioned above, the supporting rod of the grain bag is swung vertically via a swinging device, and the grain bag is vibrated from the upper side as a whole. I proposed and applied. (Akira Jitsuka
(Refer to Publication No. 59-107844) By the way, if the support rod is constantly oscillated during the grain bagging operation in this bagging device, not only will there be a large power loss, but it will also lead to early deterioration of the oscillating device. .

The present invention has been made based on the above considerations, and its purpose is to fill the grain bag with grains during grain bagging work, that is, when the shutter of the supply port is open. When this occurs, by utilizing the fact that the grains remain in the tank without being drained from the grain tank into the bag, this stagnation of grains is detected and the support rod is moved for a certain period of time or a certain number of times. By swinging, the grain bag is filled with a predetermined amount of grains reliably and efficiently even by temporary swinging of the support rod.

Therefore, the structure of the present invention is such that the supply port of the grain tank is provided with a shutter for opening and closing the supply port, and below the shutter there is provided a support rod for suspending the opening of the bag, and a pedestal for receiving the bottom of the bag. The bagging device is provided with a stagnation detection sensor that is provided near the supply port of the tank and detects stagnation of grains, and an opening motion detection sensor that detects the opening motion of the shutter, and the support While supporting the rod in a swingable manner,
a rocking device for rocking the support rod; and outputting an operation command to the rocking device when the shutter is opened by the opening motion detection sensor and when grain stagnation is detected by the stagnation detection sensor. death,
The present invention is characterized in that a controller is provided to swing the support rod for a certain period of time or a certain number of times.

The grains are filled up to the vicinity of the opening of the tank 1.
When grains are stagnant near the supply port 1a of the tank 1, the stagnation detection sensor 5 in the tank 1 is turned on,
Each support rod 2 is oscillated for a certain period of time via the motor 12, and after the oscillation of each support rod 2, when the stagnation detection sensor 5 is turned on, that is, as the support rod 2 is oscillated. When the bag 4 is completely filled with a predetermined amount of grains due to the vibration of the grain bag 4 and the grains remain in the tank 1 without further filling, the support rod 2 oscillation is stopped,
Further, if the stagnation detection sensor 5 is still turned off after the support rod 2 has oscillated for a certain period of time, it is determined that the grain bag 4 is insufficiently filled with grains, and the support rod 2 is oscillated. The movement will be resumed.

After the grain bag 4 is completely filled with a predetermined amount of grain, the shutter motor 16 is switched to the closing side, the motor 16 is rotated in the opposite direction, the shutter 17 is closed, and the closing limit switch is activated.
