Description

[Detailed Description of the Invention] The present invention relates to a shutter device for a paddy outlet in a paddy receiving section of a combine harvester.

In other words, two paddy outlets are installed side by side in the left and right direction of the machine at the bottom of the paddy tank on one side of the machine, and the two shutters facing each paddy outlet can be opened and closed manually or at the same time, and can be operated independently by a motor. Alternatively, it is possible to open and close the shutters at the same time, so that both shutters can be operated reliably, quickly, and easily, so that paddy receiving work in a combine harvester can be performed satisfactorily and suitably.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a schematic plan view of a combine harvester, in which a reaping section 3 is installed at the front left side of the machine, a threshing section 4 is installed behind it, and a control column 5 and a seat 6 are installed at the front and rear of the right front section of the machine. A paddy tank A is installed above the paddy tank A at the rear of the paddy tank A, and the paddy tank A is installed so that the grain can be hoisted from the threshing section 4 to the paddy tank A by the hoisting machine 7. Two paddy outlets a1 and a2 are arranged side by side in the left and right direction, and a paddy bag C,
C can be attached freely, and an engine section 8 is installed behind the paddy tank A to constitute a combine harvester in the same manner as the conventional structure.

In addition, in the lower part of the paddy tank A, as mentioned above, both cylindrical paddy outlets a1 and a2 are arranged side by side and spaced apart in the left and right direction of the machine, which are the front and back positions with respect to the removal side direction A of the paddy bag C. However, the front (that is, the near side) paddy outlet a
In the middle part of 1, stepped rail parts 9, 9 are formed on the left and right sides with respect to the extraction side direction A, and the upper part of both rail parts 9, 9 is narrower than the width between both rail parts 9, 9. Stepped rail parts 10, 10 are formed, and in the middle part of the rear (that is, back side) paddy outlet a2, they are on the left and right sides with respect to the take-out direction A, and have the same height as the rail parts 9, 9. Rail part 11,1
1 is formed, and each rail portion is installed so as to be open to the extraction side direction A.

B1 is a shutter made of a long plate, and parts of both side plates 12, 12, which are formed upright along both sides, are slidably inserted into both rail parts 10, 10. An upward handle 1 is formed, and a pull-out hole 13 that can match the paddy outlet a1 is formed on the back side of the shutter B1, and an upper edge of this one side plate 12 extends from the side of the pull-out hole 13 to the end side. A latch 14 is formed.

B2 is a long plate shutter that is longer and wider than the shutter B1, and is positioned below the shutter B1 so that it overlaps with the shutter B1. . With the racks 14 aligned vertically,
A rack 16 is formed on the upper edge of one of the side plates 15, which is at approximately the same height as the side plate 12, and a long hole 17 extending below the paddy outlet a1 is formed in the front half of the shutter B2. A hole 18 is formed at the end on the back side so that the hole 18 can be seen below the paddy outlet a2.

In addition, a spline shaft 20 is installed with metals 19, 19 at a position closer to the paddy outlet a1 between the two paddy outlets a1 and a2, and a pinion 21 that is slidably spline-fitted to the spline shaft 20 is attached to both racks. The shifter 23 is movably installed in a position where it engages with one or both of 14 and 16 and a position where it does not engage with both, and the movement for engagement and disengagement is performed by switching the handle (operating tool) 22 to the shifter 23 position. It is installed so that it can be done by changing the paddy outlet a1,
A chain 26 is wound around a sprocket 24 of a reversible motor M installed in the upper part of the chevron-shaped space between a2 and a sprocket 25 at the end of the spline shaft 20, so that the pinion 21 can be driven in forward and reverse directions by operating a switch.

Therefore, as shown in Fig. 11, both handles 1 and 2
With the holes aligned vertically, the paddy outlet a1 can be closed by the shutter B1 with the extraction hole 13 removed, and the paddy outlet a2 can be closed with the shutter B2 with the extraction hole 18 removed.

When operating the shutter at the front, operate the pinion 21 so that it comes off both racks 14 and 16 as shown by the imaginary line in FIG. When you pull it toward the
3 and 17 match, the paddy outlet a1 opens and paddy can be put into the paddy bag C. When the handle 2 is grasped and the shutter B2 is pulled toward the extraction side direction A, the first
As shown in Fig. 3, the extraction hole 17 remains aligned with the extraction hole 13, and the extraction hole 18 side coincides with the paddy outlet a2, so that paddy can be put into the open paddy bag C, and when only the paddy outlet a1 is closed, If the shutter B1 is pushed in from the state shown in FIG. 13, it can be closed. Of course, simultaneous operation of shutter B1 and shutter B2 is also possible.

Furthermore, if the pinion 21 is driven astride both racks 14 and 16 as shown in FIG. 4, both shutters B1 and B2 can be opened and closed simultaneously, and as shown in FIG. 14 or the rack 16 as shown in FIG. 10, the shutters B1 and B
Only one of the two can be opened and closed.

As described above, since the present invention is constructed as shown in the claims of the utility model registration, it exhibits the following excellent effects.

Single or simultaneous opening/closing of both shutters B1, B2 by manual operation and single or simultaneous opening/closing of shutters B1, B2 by reversible motor M can be selectively performed using the operating tool 22, which is extremely convenient for work.

If a forward/reverse switch for the reversible motor M is installed near the driver's seat, a single worker can operate the machine and the shutters at the paddy outlets a1 and a2, without having to go down to the field, especially when working in wet fields. Since the shutter can be operated, work efficiency is improved.

Shutters B1 and B2 such as reversible motor M
By installing the driving parts in the chevron-shaped space between the two rice grain outlets a1 and a2, both shutters B1 and B
Since it can be easily installed in a limited space without interfering with the opening and closing of the combine harvester, it can be installed at a low cost even on existing combine harvesters.
