Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grain tank structure for a grain bagging device.

[Conventional technology]

Conventionally, in grain bagging equipment, for example,
As shown in Publication No. 59-16350, by attaching a shutter to the discharge cylinder of the grain tank, grain discharge can be stopped when bagging is not performed or when full bags are replaced with empty bags. was made possible. Then, a boot section is attached to a portion of the discharge tube located below the shutter so as to be able to slide up and down, and when supplying grains to the bag, the boot section is placed in the lowered mounting position, so that the bag support rod can be attached to the boot section. A boot section is inserted inside the hanging bag to prevent grains from falling out, and the boot section can be mounted in a raised position when removing a full bag from the bag support rod or setting an empty bag in the filling position. By adjusting the position, you can pull the boot part out of the bag or reduce the length of the boot part into the bag.
The boot part is designed to be less likely to become an obstacle to bag sliding, making it easier to replace the bag.

[Problem that the invention attempts to solve]

In the case of conventional equipment, it is necessary to secure space between the grain tank and the boot section to install the shutter and its attached components, and in the case of bagging equipment, it is necessary to secure a space between the grain tank and the boot section to install the shutter and its attached components. For example, in the case of a combine harvester, because the placement level of the support rods cannot be lowered too low, the grain tank placement level becomes high and the weight of the stored grain makes the machine unstable, or the machine body becomes unstable. In order to stabilize the grain tank, it is necessary to lower the arrangement level of the grain tank, resulting in a smaller tank capacity.

The present invention was developed in view of the above circumstances, and while preventing grain spillage,
In addition, the structure of the grain tank of the grain bagging device allows bagging to be carried out while making it easy to exchange bags, and also allows the grain tank to be installed at a low height to ensure stability of the aircraft while increasing the capacity of the grain tank as much as possible. For the purpose of providing.

[Means for solving problems]

In order to achieve the above-mentioned object, the grain tank structure of the grain bagging device according to the present invention has a discharge cylinder that is vertically disposed in the grain tank for discharging the grains from the grain tank and bagging them. A lid for the discharge cylinder is provided in a position directly above the discharge cylinder in the grain tank, and the position of the lid for the discharge cylinder is such that when the discharge cylinder is in the highest position, The approach of the upper end side of the discharge tube prevents grains from flowing into the discharge tube, and when the discharge tube is lowered, the upper end of the discharge tube is separated from the upper end side of the discharge tube. The space between the opening and the lid for the discharge cylinder is opened, and a passage for grains is left between the edge of the lid and the inner surface of the grain tank, so that the grains can be transferred to the discharge cylinder. The characteristic configuration is that it is configured to allow inflow.

The functions and effects of this characteristic configuration are as follows.

[Effect]

In other words, when the dispensing tube is placed in the highest position, its upper opening is closed by the dispensing tube lid and grain discharge is stopped, and when the dispensing tube is lowered, the upper opening is opened and grains are discharged. Since the grains are discharged from the opening through the discharge tube, a mechanism corresponding to the conventional shutter configuration is located inside the grain tank, and when filling the grain, the lower side of the discharge tube is Inserting the discharge tube into a bag, pulling it out from the bag when replacing the bag, and changing the vertical position of the discharge tube also serves as an operation for inserting and removing the discharge tube from the bag.

[Effect of idea]

Therefore, by raising and lowering the discharge tube, it is possible to insert this discharge tube into a bag to avoid spilling when filling grains, or to prevent the discharge tube from entering the bag so that it is less likely to become an obstruction. Bags can be replaced easily, making bagging work more efficient while avoiding losses due to grain spillage.

Furthermore, since the shutter mechanism is located inside the tank, the distance between the grain tank and the bag can be made relatively small, making it possible to maximize the capacity of the grain tank and, in the case of combine harvesters, This is advantageous in that the number of work interruptions for unloading can be reduced. In addition, the grain tank can be arranged at a relatively low level, which has advantages such as minimizing the height of the device and preventing the center of gravity from increasing due to the weight of stored grains. I've reached it.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Fig. 4, the grains from the threshing device 1 are supplied to the grain tank 3 by the grain lifting device 2, and a bag storage section is configured to hang an empty grain bag 4 on the inner side of a pair of bag support rods 5, 5. The grain bags 4 are taken out one by one from the bag storage section to a loading position on the tip side of the bag support rods 5, and the threshed grains are dropped and discharged from the grain tank 3 into the grain bag 4 by the discharge tube 7 while the grain bag 4 is supported by being hung by the bag support rods 5 and received by the bag receiving deck 6. Thus, a grain bagging device for a combine harvester is configured.

As shown in FIG. 1, the discharge tube 7 is fitted into the bottom of the grain tank 3 so as to slide up and down, and is attached to the grain tank 3 via a swing support link 8 and a mounting member 9. There is. An operation tool 1 for raising and lowering the discharge cylinder is slidably attached to a mounting member 9 in conjunction with a swing support link 8.
0 to the first operating position DN, the swing support link 8 is operated and maintained in the mounting position shown in FIG. 2 due to the operating tool operating force and the spring 11, and the discharge tube 7 is moved to the filling position Grain bag 4 in
When the operating tool 10 is operated to the second operating position UP, the swing support link 8 is moved to the mounting position shown in FIG. 1 due to the operating tool operating force and the spring 11. It is configured such that the discharge cylinder 7 is lifted out of the grain bag 4 in the filling position and is in a raised mounting state. The lid 12 for the discharge cylinder 7 is fixed inside the grain tank 3, and as shown in FIG. covers the upper end side of the discharge tube 7, so that the lid body 12 closes the upper end side opening 7a of the discharge tube 7 and prevents the threshed grains from flowing into the discharge tube 7, and the discharge tube 7 In this state, as shown in FIG. 1, the discharge tube 7 is separated from the lid 12 and a grain flow gap is formed between the lid 12 and the upper end of the discharge tube.
is configured to allow grains to flow into the discharge tube 7.

In other words, when the operating tool 10 is operated to the first operating position DN, the discharge tube 7 can be inserted downward into the grain bag 4 so that the grains are less likely to fall out, and the threshed grains can be dropped into the grain bag 4. The grain tank 3 is now in an open state. When the operating tool 10 is operated to the second operating position UP, the discharge tube 7 rises so that it is less likely to become an obstacle when attaching and detaching the grain bag 4 to the filling position, and the grains are moved up so as to stop the threshed grains from falling. The tank 3 is now in a closed state.

Here, the lid body 12 has the function of receiving the load from above the grains stored in the grain tank 3, so that the discharge part at the lower end of the grain tank 3 and the grain tank 3
This makes it difficult for the grain bridging phenomenon, which causes grains to become clogged with the wall surface of the grain, to occur.

[Another example]

The present invention can be applied not only to combine harvesters but also to stationary grain bagging equipment.
