Description

[Detailed explanation of the invention] (a) Industrial application field The present invention relates to the structure of an increase tank attached to a grain tank of a combine harvester.

(B) Prior Art Conventionally, in a combine harvester, a technology has been known in which an increase tank is attached to a grain tank in order to be able to store a large amount of grain after threshing and sorting. For example, see Utility Model Publication No. 56-2853. However, when the increase tank is constructed in the shape of a triangular prism and can be stored in the grain tank as in the known technique, the size of the increase tank is determined by the width of the upper side of the triangular prism that can be stored in the grain tank.
The width is limited to no more than the depth of the grain tank.

In order to exceed this limitation and increase the capacity of the expansion tank 1, when the front and rear plates of the triangular expansion tank protrude from the back plate of the grain tank, a protrusion that can be fitted into the rear plate of the grain tank should be protruded into the back plate of the grain tank. It is necessary to do so.

The technology configured in this way was developed by the same applicant.
It was filed as Utility Model Application No. 1847-1983.

(c) Problems that the invention seeks to solve However, providing protrusions to protrude the front and rear plates of the bulking tank from the back plate of the grain tank, as in the earlier application of the same applicant, is a problem in terms of sheet metal processing costs. That's why it's expensive.

In this invention, in order to eliminate the protruding part from the back plate part of the grain tank, the protruding parts of the front and rear plates of the bulking tank are cut out, and since this part is missing, the bulking tank 1 is placed on the bulking side. A notch cover 2 is provided to cover the triangular part that opens when the tank is rotated from the inside, and the notch cover 2 is attached to the tank ceiling plate 3 of the tank 1.

(d) Means for solving the problem The purpose of the present invention is as described above. Next, the configuration for achieving the purpose will be explained.

A triangular prism-shaped increase tank 1 with the top pivoted at the lower end is rotatably supported on the outside of the grain tank 4 made of a rectangular parallelepiped. In a large configuration, the portion where the triangular apex portions of the front and rear walls interfere with the back plate of the grain tank 4 is defined as a notch portion 1a, and when the volume increase tank 1 is rotated toward the volume increase side, the notch portion 1a
A notch cover 2 that closes the part a is attached to a foldable tank ceiling plate 3.

(e) Structure of the embodiment The purpose and structure of the present invention are as described above. Next, the structure of the embodiment shown in the attached drawings will be explained.

Figure 1 is an overall side view of a combine equipped with the grain tank device of the present invention, Figure 2 is a front sectional view of the grain tank, Figure 3 is an exploded perspective view of the bulking tank, and Figure 4 is the bulking tank. A front sectional view when the ceiling plate 3 is in the stored state, FIG. 5 is a side view showing the configuration of the end of the notch cover 2, and FIG. 6 is a top plate of the increase tank when the increase tank 1 is in the increase state. FIG. 3 is a front sectional view showing FIG.

The overall structure of the combine harvester will be explained with reference to FIG.

The engine compartment 14 is located behind the seat 15 of the combine.
The grain tank 4 is arranged at the rear of the engine room 14. A triangular prism-shaped increase tank 1 is pivotally supported at its lower end on the right side of the grain tank 4 in the direction of travel so that it can be protruded and stored. The grains stored in the grain tank 4 are collected by a grain collecting auger 7 at the lower end of the grain tank 4, transported rearward, and then transferred to an upper discharge auger 9 by a vertical auger 8. The discharge auger 9 unloads the cargo onto the platform of a transport vehicle or truck on the ridge. A vertically horizontal rotating mechanism 13 is arranged between the discharge auger 9 and the vertical auger 8.
Reference numerals 17 and 17 are exhaust ports of a ventilation device, which will be described later.

Next, this will be explained with reference to FIG. The top of the volume increase tank 1 configured in the shape of a triangular prism is disposed at the lower end, and is pivotally supported to the grain tank 4 as a pivot support 1c. Therefore, the upper part of the triangular prism-shaped increase tank 1 can be freely protruded and stored around the pivot portion 1c. The width of the base of the triangular prism corresponding to the ceiling portion of the increase tank 1 is wider than the width, that is, the depth of the grain tank 4. Therefore, if the triangular prism is housed in the grain tank 4 as it is, the top of the base will protrude from the back plate of the grain tank 4. This part is the front and rear plates 1b, 1
Conventionally, a protrusion is provided on the back plate of the protruding portion, and the front and rear plates 1b, 1 are inserted into this protrusion.
It was fitted with b. However, since this increases the manufacturing cost, at this cost, the portions of the front and rear plates 1b, 1b corresponding to the protrusions are cut out as the notches 1a.

By making the part of the front and rear plates 1b, 1b that interferes with the back plate into the notch part 1a, when the increase tank 1 is rotated and protruded to the increase side, the space between the grain tank 4 and the increase tank 1 will be removed. As a result, an opening corresponding to the notch 1a is created. In the present invention, the opening created by the notch 1a is shielded by a notch cover 2 attached to the ceiling plate 3 of the bulking tank.

When the volume expansion tank ceiling plate 3 is in the volume expansion state, it is spread out as shown in FIG.
It is folded at certain bends and stored as shown in Figure 2.

The notch cover 2, which is the essential part of the present invention, is attached to the lower surface of the front and rear ends of the inner ceiling plate 3a of the expansion tank ceiling plate 3. In the stored and folded state, the notch cover 2 is attached to the front and rear plates 1.
b, 1b.

Further, as shown in FIG. 5, the inner edge of the notch cover 2 has a bent edge 2a in the outward direction, and the bent edge 2a contacts the inner surface of the outer wall of the increase tank 1, preventing it from being pulled out any further. This means that it is locked in place. In addition, a rubber sag hangs down from the upper part of the pivot shaft 10, and the rubber sag 12 is pushed by the pressure of the stored grains to the pivot shaft 10 as shown in FIG.
This seals the small gap that occurs near zero.

FIG. 7 is a side sectional view of a state in which a ventilation device is configured in the grain tank, and FIG. 8 is a plan sectional view of the same.

An engine E and a radiator 18 are arranged in the engine room 14, and hot air is discharged from the engine E and the radiator 18. The hot air from the engine room 14 is forced by the blower fan 5 and blown into the grain layer in the grain tank 4 through the blower ducts 16, 16. The discharged air blown out from the air ducts 16, 16 is
It is discharged to the outside from the grain collection auger 7 or the exhaust port 17. This makes it possible to cool grains that are stored in the grain tank 4 for a long time, generate heat, become high temperature, and are at risk of deterioration.

In addition, as shown in FIG. 7, a circulation discharge port 20 is provided in the discharge auger 9, and if this part is normally closed by the shutter 19, ventilation can be made from the ventilation fan 5 even during the grain reaping operation. In addition, the grains inside can be circulated, and the entire grain inside the grain tank 4 can be cooled.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

Firstly, it is possible to use a triangular prism having a width larger than the depth of the grain tank 4 as the bulking tank 1, and the capacity of the bulking tank 1 can be increased. The amount of storage can be increased.

Second, unlike the conventional technology, there is no need to form a protrusion on the protruding portions of the front and rear plates 1b, 1b to fit the protrusions, and the processing cost of the grain tank 4 can be reduced. .
