Description

[Detailed Description of the Invention] The present invention relates to a shutter device suitable for application to a rice grain processing hopper of a combine harvester.

FIG. 1 is an assembly diagram showing a state in which a shutter is installed in a rice processing hopper of a combine harvester which is generally popular, and FIG. 2 is a detailed diagram of the shutter.

In Fig. 1, A, B, C, and D are hoppers arranged in series, and at the bottom of each hopper there are outlets Al
, A2. Bl, B2. CI, C2, DI, D2 and shutter guide E 1. E2 and outlet F1. F2 is provided.

Reference numeral 11 denotes a dual-use shutter for both the left and right phase outlets F, F2, which are arranged side by side, and the shutter guide E1. It is fitted in E2 so as to be slidable in the horizontal direction.

In Fig. 2, 11a and 11b are discharge holes, IIC,
lld is a part of the shutter, and 11e is a handle.

Therefore, conventional shutter devices such as hoppers are configured to simultaneously close or open the left and right side-by-side discharge ports F, F2 with one shutter 11. It is impossible to discharge the grains individually from the F2, and the following problems occur during the bagging operation.

(i) When a small amount of grain remains in each hopper and the grain is stored in one bag, the grain is discharged from each outlet into each bag and then refilled into one bag.

If you only have one bag, you will have trouble storing grain.

(ii) In continuous reaping and harvesting work where the driver and assistant share the duties of operating the combine and processing the paddy, the bags are arranged facing toward the front where it is easier to attach and take out the bags for work efficiency. If discharge is required only from the discharge port (F2°F2.F2.F2), or if the field is a wet field, it is necessary to reduce the weight of the machine, but in that case, the rear shutter should be closed as described above. Although it is possible to change the bag by changing only the bag on the front side and making it possible to work in wet fields, it cannot be adapted to these situations.

(iii) There is often a difference in yield between the grains stored in the left and right bags for the left and right discharge ports F1 and F2, especially when the grains in the hopper are biased to either the left or right side. The difference in yield becomes significant, and it is therefore difficult to store the same amount of grain in the left and right bags.

This invention was proposed with the aim of solving the above-mentioned problems with the conventional hopper discharge port shutter device and allowing various shutter operations to be performed in accordance with the actual work conditions of the combine harvester. Exhaust port F...
A single-discharge shutter device according to the first patent, characterized in that shutters 1 and 2 are provided to open and close F2, respectively, and a switching device 3 is provided to switch and operate the shutters 1 and 2 so that they can communicate or separate from each other. This is related to.

The present invention will be explained in detail below with reference to embodiments shown in FIGS. 3 to 6, A9 and C.

In addition, in the figure, only one of the hoppers A, B, C, and D (see Figure 1) arranged in series on the side of the combine body is shown, and only one example is shown for the hopper A, and the other hoppers B, C and D are omitted as they are the same mechanism.

In those figures, A1 and A2 are the left and right exits installed at the bottom of the hopper A, El and E2 are the shutter guides, and F
1 and F2 are outlets.

Shutters 1 and 2 discharge or restrict the discharge of grain in the hopper A, and are fitted into the shack guides E1 and E2 so as to be slidable in the left and right horizontal directions, as shown in FIG.

The shutter 1 is a rectangular iron plate, and as shown in FIGS. 3 and 4, an opening 1a is bored near the left end face in the longitudinal direction for use when discharging grains, and the right end is folded on both left and right sides. It has music mounting parts 1b, lb.

On the other hand, the shutter 2 is a rectangular iron plate similar to the shutter 1, and has an opening 2a in the vicinity of the left end surface, and an engaging member 2b having a U-shaped cross section on the upper right end surface. are fixed perpendicular to the longitudinal direction.

Reference numeral 3 denotes a switching device for connecting and disconnecting the shafts 1 and 2, and as shown in FIG. 3b, the image end portions of the rods 3a, 3a are fixedly connected to the bent mounting portions 1b, 1b of the shutter 1 via a pin 4, and mounted on the shutter 1 so as to be freely rotatable about the pin 4. has been done.

By rotating the switching device 3, the engaging member 3b is fitted into the U-shaped groove of the engaging member 2b of the shutter 2,
Also, the shutter 1 and shutter 2 are removed from the groove.
It is configured to allow both linked operation and independent operation.

One embodiment of the device of the present invention is constructed as described above.Next, the opening/closing operation of the shutter will be explained.

(a) When both discharge ports F and F2 are closed simultaneously.

(See Fig. 3) Fit the retaining member 3b of the switching device 3 into the U-shaped groove of the engaging member 2b of the shutter 2, and

are interlocked horizontally to the right or left within the shutter guides E, E2, and as shown in FIG. 3, the left and right exits A1, . A
By keeping the outlets F and F2 in a shielded state, the grains are prevented from being discharged from the outlets F and F2.

(b) When simultaneously discharging from both discharge ports Ft and F2 (see Fig. 6A) Both discharge ports F1 shown in Fig. 3. From the time of simultaneous closing of F2, pull the retaining member 2b (handle) to the right, and move the shutters 1 and 2 to the shutter guide type 1. E2 is interlocked in the right horizontal direction, and the openings 1a of shutters 1 and 2 are opened as shown in Fig. 6A.
, 2a are placed opposite the left and right outlets A, , A2 of the hopper A, the left and right outlets A, , A2 are unshielded, and the grains are simultaneously discharged from the discharge ports F, , F2.

(C) When the discharge port F1 is closed and the discharge is discharged from the discharge port F2 (see Figure 6) When the switching device 3 is rotated upward about the pin 4, the retaining member 3b of the switching device 3 locks the shutter 2. Joining part 2
The shutters 1 and 2 are released from the U-shaped groove b, and the engagement and connection between the shutters 1 and 2 is released, and each shutter 1 and 2 can be operated independently. Part 1C shields the outlet A1 of the hopper A,
On the other hand, by arranging the opening 2a of the shutter 2 to face the outlet A2, the grains in the hopper A are transferred to the outlet A2.
Since the discharge port F1 is closed, the discharge from the discharge port F1 is prevented, but since the discharge port F2 is open, the discharge from the discharge port F2 is blocked.

By facing the exit A2 with the shutter part 2C of the shutter 2, the hopper A
Since the outlet A1 is open, the grains inside are discharged from the outlet F1, or because the outlet A2 is closed, the grains are prevented from being discharged from the outlet F2.

As mentioned above, this device divides the shutters at the exits of two hoppers arranged side by side into two, engages and connects these two shutters, and is equipped with a switching device that can release this engagement. This makes it possible to simultaneously operate these two shutters in conjunction with each other and to operate them independently, making it possible to simultaneously discharge grain from both discharge ports, cancel simultaneous discharge, and discharge grain only from one side at will and easily. , the following effects can be obtained.

(1) When a small amount of grain remains in the hopper, it is now possible to store all grains in one bag by operating the shutters individually.

This is especially convenient if you only have one bag on hand.

(2) During continuous work, the discharge ports facing the front (F2 in Fig.
) By freely selecting and operating the discharge from the bag, it is possible to significantly improve work efficiency, and even in wet rice fields, the rear shutter can be closed and only the front bag replaced as described above. By reducing the overall weight of the machine, it is possible to work in wet fields.

(3) During continuous operation, even if the remaining grain in the hopper is shifted to the left or right and there is an extreme difference in yield between the left and right bags, the shutters 1 and 2 can be operated independently from side to side as appropriate. , it is possible to store the same amount of grain in the left and right bags.

(See the *marked part in Figure 3) (4) When replacing bags, both shutters can be closed at the same time, allowing you to concentrate on replacing bags without worry even if grains remain in the hopper. When taking out all the grains stored in the bag into bags, the two shutters can be operated in conjunction and the outlet can be used at the same time to efficiently take out the grains into the bags. It is.
