Description

[Detailed Description of the Invention] This invention relates to a grain tank device that can store a large amount of grain by effectively utilizing the space above the fuselage of a combine harvester.

Grain that has been threshed and sorted in a combine is usually packed directly into bags, or once stored in a hopper and then packed into bags, but with these methods, operation must be stopped when changing bags. This has the disadvantage that the continuous operation time is short and the operating rate does not improve.

By the way, the height of the combine harvester is limited as it is a special vehicle, but in reality, the height of the main body of the machine, such as the threshing equipment and waste straw processing equipment, is considerably lower than the above-mentioned height limit, and there is sufficient space above the machine. be.

Therefore, a technique has been proposed that utilizes the upper space of such a threshing device to increase the amount of grain stored. For example, it is disclosed in Japanese Utility Model Publication No. 55-23329. The technology disclosed in this publication extends the vertical tank side chamber to the upper part of the threshing device as an upper chamber, and as a result, a discharge spiral is provided to push the grains into the upper chamber. . Furthermore, in order to completely discharge the grains in the tank, the upper chamber is tilted toward the side chamber to ensure that the grains fall into the grain intake opening of the grain frying spiral tube at the bottom of the side chamber. The ejection spiral tube is rotated in the longitudinal direction and the lateral direction of the machine body for the purpose of switching between a state in which grain is discharged and a state in which it is not used.

In such a conventional grain tank, in order to increase the amount of grain stored, it was necessary to provide a special means requiring a drive transmission mechanism, that is, the above-mentioned discharge spiral.

This idea focuses on the space above the machine and makes effective use of it to increase the amount of grain stored, making it possible to operate continuously for long periods of time, which was a drawback of conventional machines. Moreover, as the amount of grain stored increases, a simple means is adopted to uniformly transport the grain over the expanded area, and the details thereof are based on the illustrated embodiment. The explanation is as follows.

In Figs. 1 to 3, 1 is a threshing device; 2 is a threshing device;
is a waste straw processing device in which a waste straw conveyance chain and a waste straw vine are installed, and a horizontal tank 4 is provided on the back side of the threshing device 1, that is, on the side opposite to the grain rod feed portion 3 of the threshing device 1. It is permanently installed. This horizontal tank 4 is a vertically elongated grain tank that is the same height as or higher than the threshing device 1, and its bottom is constricted into a funnel shape, and a normally closed shutter 5 is interposed at the lowest part. A horizontal conveyor 6 for taking out the threshing device 1 passes through the lower side. On the other hand, a horizontally long upper tank 7 is provided at the top of the threshing device 1. This upper tank 7 is open at least at the end of the horizontal tank 4, and this open end projects into the upper part of the horizontal tank 4, so that it can be raised and lowered around the end of the horizontal tank 4. It's summery. In this illustrated example, the upper part of the upper tank 7 is also open. 8 is a hydraulic cylinder for lifting the upper tank 7.
Further, a horizontally long box-shaped rear tank 9 is provided at the upper part of the waste straw processing device 2. This rear tank 9 is adjacent to the upper tank, and can be raised and lowered around a shaft support 10 at the upper part of the front end, and has an open upper part so that the grains inside can flow down into the upper tank 7 when the rear tank 9 is erected. . 11 is a hydraulic cylinder for lifting the rear tank 9. 12 is a vertical conveyor that fries grains from the 6th end of the horizontal conveyor, and its discharge port 13
is open in the upper part of the horizontal tank 4. Reference numeral 14 denotes a swing conveyor connected to the upper end of the vertical conveyor 12, which can rotate around the vertical conveyor 12 and move up and down, and its discharge port 15 can be exposed onto the upper tank 7 and the rear tank 9. .

In the above configuration, the grains threshed and sorted by the threshing device 1 are transferred to the horizontal conveyor 6 and the vertical conveyor 1.
2, it is first sent into the horizontal tank 4. At this stage, the shutter 5 of the horizontal tank 4 is closed.
Next, when the horizontal tank 4 becomes full, the grain outlet is switched. That is, in response to the operation of a sensor (not shown) in the horizontal tank 4, the discharge port 13 of the vertical conveyor 12 is closed by a shutter, and the grains are conveyed to the upper tank or the rear tank 9 by the swinging conveyor 14. It will be done. This series of operations may be performed automatically, or may be controlled by an operator while checking the operation of the sensor. When either the upper tank 7 or the rear tank 9 is full, the swinging conveyor 14 pivots and feeds grain into the other tank.

When the horizontal tank 4, upper tank 7, and rear tank 9 are all full, the machine is stopped and the grains in the tanks are transferred to a transport vehicle such as a truck. In that case, first swing the swinging conveyor 14 onto the transport vehicle, open the shutter 5 of the horizontal tank 4, and transport the grains from the horizontal conveyor 6 through the vertical conveyor 12 and the swing conveyor 14 onto the transport vehicle. . When the horizontal tank 4 is empty, the upper tank 7 is raised by the operation of the hydraulic cylinder 8, and the grains inside are dumped into the horizontal tank 4.
Then, carry out the same operation as described above to take it out to the transport vehicle. When the upper tank 7 is empty, the rear tank 9 is raised by operating the hydraulic cylinder 11. As a result, the grains in the rear tank 9 flow into the upper tank 7.
By standing up the grains, the grains flow into the horizontal tank 4 and are carried out.

In the example shown in FIGS. 1 to 3, the grains in the rear tank are fed into the upper tank, but it may be configured so that they can be fed directly into the side tank. An example of this is shown in FIGS. 4 to 6, in which the upper tank 7' has an open end beside the horizontal tank 4', and the open end protrudes into the upper part of the horizontal tank 4'. The front end of the rear tank 9' is open beside the horizontal tank 4', and the open end of the rear tank 9' projects into the upper part of the horizontal tank 4'. The upper parts of the upper tank 7' and the rear tank 9' are covered with a top plate,
Arc-shaped elongated holes 16 and 17 are formed at locations corresponding to the discharge ports 15 of the swing conveyor 14. The upper tank 7' is raised and lowered by the operation of the hydraulic cylinder 8 around the end of the side tank 4', and the rear tank 9' is raised and lowered around the front end by the operation of the hydraulic cylinder 11'. This is the same as the example shown in FIGS. 1 to 3. It is preferable that the bottom of the rear tank 9' be sloped in order to bring the grains closer to the side tank 4'. Reference numeral 18 denotes an extendable cover that covers the upper part of the horizontal tank 4'.

In the example shown in FIGS. 4 to 6, by raising the upper tank 7' or the rear tank 9' separately, the grains therein flow directly into the horizontal tank 4'.

Note that the top cover of the waste straw processing device 2 may be in the form of a flat plate and does not need to be formed into a fixed shape, so the bottom plate of the rear tank may also serve as the top cover of the waste straw processing device 2. . The embodiment shown in FIG. 7 is such that the rear tank 9'' is just large enough to cover the top surface of the waste straw processing device 2, and its bottom plate 9″a serves as the top cover of the waste straw processing device 2. There is. The rear tank 9'' is raised and lowered centering on its front end, and lifted up by a hydraulic cylinder 11'', which is almost the same as in each of the embodiments described above.

As mentioned above, this device has a horizontal tank fixed to the back side of the threshing device that reaches almost the bottom of the device, and an upper tank and a rear tank are installed at the top of the threshing device and the top of the waste straw processing device, respectively. The upper tank can be raised and lowered around the side of the horizontal tank, and the rear tank can be raised and lowered around the front end, and a grain outlet is provided in the horizontal tank side part of the upper tank and the front part of the rear tank. provided, and
Since the grain discharge ports are opened on the upper tank and the rear tank so as to be able to rotate freely, compared to the conventional tank, the other upper and rear two of the horizontal tank, which is the original tank,
The grain storage capacity is increased at two locations, enabling long-term continuous operation, and the grain discharge port described above is rotated to evenly distribute the grain to the two locations, the upper and rear locations. By using simple means, it has been possible to achieve the effect that it can be implemented at a lower cost than the conventional discharge spiral which requires a drive mechanism. And, because this simple structure of the rotating means of the discharge port is adopted, the above-mentioned 2.
Tank expansions in several locations could easily be accomplished without significantly increasing costs.

Moreover, since the upper tank and the rear tank can be raised and lowered, by raising them up, all the grains inside can be taken out without leaving any residue, and there is no problem in transferring the grains.

Further, since the upper tank and the rear tank can be lifted, by lifting them, inspection and repair of the inside of the threshing device and the waste straw processing device can be easily performed without any hindrance.
