Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel loading device for full grain bags in a combine harvester, which is capable of loading a large number of full grain bags during harvesting operations.

When harvesting using a combine harvester, if the target field is a wet field, it is not possible to release the full grain bag from the combine into the field.In this case, the full grain bag cannot be loaded onto the combine. Harvesting work continues, and when the combine harvester is located along a ridge, the bags full of grain are unloaded.

Furthermore, even if the target field is a dry rice field, when discharging full grain bags all at once to a specific location as described above, it is different from discharging individual full grain bags one after another into the field. This method is also used because it is more efficient and eliminates the need to manually collect grain bags later, but as combine harvesters become larger and the target field becomes wider, the specific release rate increases. The number of grain-filled bags that are harvested by the time the combine harvester moves to the location increases, and the problem arises as to how to load such a large number of grain-filled bags onto the combine harvester.

The present invention seeks to provide a loading device for grain-filled bags which addresses the above-mentioned problems and which is also extremely suitable for the purpose.

With regard to the illustrated embodiment, the configuration of the loading device for grain-filled bags in the combine harvester according to the present invention will be described.
The combine shown in Figure 2 has a pair of left and right crawlers 1,
The combine harvester is constructed of a serial type in which a reaping section 3 that pulls up the grain culm, reaps it, and transports it to the rear extends from the upper body of the combine harvester 2. It is located at the top of 1,
Further, the threshing device 4 is configured as a horizontal blowing type device that is vertically elongated in the longitudinal direction of the machine body.

Further, downstream of the threshing device 4, in the illustrated case, there is a waste straw processing device configured as a waste straw cutter 5 (other examples of the waste straw processing device include a dropper or a tying machine).

) is installed, and this straw removal cutter 5 is equipped with a threshing device 4.
A conveyor belt 6 is provided between the threshing device 4 and the straw cutter 5 to transport and feed the waste straw from the straw in the inward direction of the machine body so that the stock side of the waste straw is removed from the uncut ground.

In the figure, 7 is a feed chain of the threshing device 4, and 8 is a head rest at the front of the threshing device 4.

In the combine harvester of FIGS. 1 and 2 constructed as described above, the grain-filled bag loading device according to the present invention is constructed as follows.

That is, on the upper surface of the threshing device 4, according to the present invention,
A loading platform 9 for grain-filled bags is installed, and this loading platform 9, as shown by chain lines in FIG.
The cutter 5 extends above the rear end of the cutter 5 (in the illustrated case, slightly further rearward and above the rear end of the cutter 5).

In the illustrated embodiment, this loading platform 9 is also the first
As shown by the chain line in the figure, the front end side is placed on the tip resting stand 8.
At the same time, one side edge extends to the outside of the feed chain 7, and as shown in FIG. 2, a rising portion 9a is formed on the edge.

In addition, in the illustrated case, the loading platform 9 is supported by a hinge 11 that allows the upper lid 10 of the threshing device 4 to be rotatably opened and closed, and is rotatably supported by the machine body together with the upper lid 10. Fixing the loading platform 9 means using an appropriate detachable fixing means (not shown) on the free end side of the loading platform 9.
This is done by fixing it to the aircraft body.

A step 12 is installed on one side of the threshing device 4 so as to be located above the right crawler 2. In the illustrated case, this step 12 is connected to the straw removal force from the front end position of the threshing device 4 to the straw removal force 5. It is configured to be long in the front and back across the rear end position and parallel to the loading platform 9.

Further, in the figure, reference numeral 13 is a grain discharge cylinder, and a support cylinder 14 is connected to this grain discharge cylinder 13 and is placed along one side of the threshing device 4. End tube 15,1
6, and the front and rear grain bagging parts 17, 18 each having a pair of parallel bag support rods 17a, 18a are provided below each discharge end tube 15, 16 on the step 12, and between them. They are spaced and set.

In the figure, 19 is a passenger seat for the operator.

Since the combine harvester shown in FIGS. 1 and 2 is constructed as described above, it is possible to load bags full of grain obtained one after another during harvesting operations in the following manner.

That is, in addition to the operator on the seat 19, the wide step 1
An assistant rides on the combine harvester and replaces the grain storage bag A, and also places the full grain bag on the combine harvester appropriately. Since the table 9 is installed on the threshing device 4, the grain-filled bag can be loaded not only on the step 12 but also on this wide-area loading table 9, and the assistant on the step 12 can: Step 12: Select an appropriate position in consideration of the left-right balance of the machine, and move the grain-filled bags obtained one after another into step 12.
It is possible to load not only on the top but also on the loading platform 9, thereby making it possible to load a very large number of full bags of grain onto this combine harvester.

The large number of grain-filled bags loaded as described above are unloaded all at once onto the ground or onto a transport vehicle when the combine is moved to a ridge or roadside.
As mentioned above, since the loading platform 9 on the threshing device 4 extends above the rear end of the straw cutter 5, during the above-mentioned unloading operation, the grain-filled bags on the loading platform 9 are It can be loaded and unloaded one after another by being placed on the shoulder from the rear end.
Therefore, loading and unloading of bags full of grains can be carried out very easily.

In this case, if the loading platform 9 is given a slight backward inclination, it will be easier to move the full grain bag to the rear end on the loading platform 9.

As described above, the loading platform 9 that extends above the rear end of the straw cutter 5 provides a wide loading area capable of loading a large number of full grain bags, and also In addition to facilitating loading and unloading, the loading platform 9 extended as described above also functions as a safety cover for the waste straw cutter 5 and the conveyor belt 6 that supplies waste straw to it, so that it can be easily loaded and unloaded during harvesting operations. This guarantees the safety of workers.

In addition, in order to further demonstrate the function as this safety cover, skirts can be easily provided on both side edges and the rear edge of the rear extension of the loading platform 9 from the threshing device 4. be.

Next, another embodiment of the grain-filled bag loading platform 9' shown in FIG. 3 will be described. In particular, it is structured as follows.

That is, this loading platform 9' is configured with a large number of parallel rollers 23 that are rotatably supported by the edges 20 and 21 on both sides, and the bag loading surface of this loading platform 9' is aligned with the horizontal surface L. It is installed on the threshing device with a slight inclination α toward the rear downward force, and an upright wall 25 rotatable around a support shaft 24 serves as a stopper at the rear end of the loading platform 9'. The upright wall body 25 is normally held in an upright position by a detachable stopper 26.

Therefore, when loading and unloading the full grain bags loaded on the loading platform 9', the stopper 26 is released and the upright wall 25 is rotated around the support shaft 24 to hang down.
The grain-filled bag on '
With the help of the rotation of the bags, the bags are automatically sent to the rear end side of the loading platform 9', making it extremely easy to load and unload the bags.

In addition, during bag loading and unloading, the upright wall 25 or other members may be used to form a steeper bag sliding or transfer loading/unloading guide surface that is continuous with the upper surface of the loading platform 9'.

Furthermore, the loading platform 9' shown in FIG. 3 is particularly provided with a support 27 for supporting an extension from the threshing device.

As is clear from the above description, the loading device for the full grain bags in the combine harvester of the present invention has a loading platform installed on the top surface of the threshing device and extending above the rear end of the waste straw processing device. As a result, a bag loading section with a wide area can be obtained and a large number of grain-filled bags can be loaded, which makes it possible to carry out continuous operation without releasing grain-filled bags, thereby increasing the efficiency of transporting the bags. This loading platform extension part that covers the upper part of the waste straw processing apparatus covers the waste straw processing apparatus or the waste straw conveyance belt to the processing apparatus, thereby providing safety. From this loading platform that extends to the rear end of the waste straw processing device, grain-filled bags can be loaded and unloaded using the rear force of the waste straw processing device, making it easy to load and unload the loaded bags. It has a remarkable effect.
