Description

[Detailed Description of the Invention] The present invention relates to a grain tank device for a combine harvester in which grain culms harvested in a reaping part are threshed and sorted in a threshing part, and only the sorted grains are stored in a grain hopper, which is a grain tank. Conventionally, there has been a technology to provide a small-capacity paddy bag and a large-capacity paddy bag interchangeably.

However, when a large-capacity paddy bag is used in the conventional technology, the lower part of the paddy bag tends to expand from side to side due to the grains, making the support of the paddy bag unstable. There were structural problems such as not being able to easily expand the paddy bag support structure, and also not being able to simplify the rice bag support structure.

However, the present invention provides a grain tank device for a combine that is provided with a grain hopper into which grains are placed, and in which the grains are taken out from the grain hopper through a funnel part and packed into bags. An auxiliary tank equipped with an auxiliary tank is removably provided below the grain hopper, and the vertical width of the lower tank part with a non-deformable structure is made smaller than the distance between the lower end of the grain hopper and the auxiliary tank installation surface. The lower end of the upper tank is integrally connected to the upper end of the lower tank, and the upper end of the upper tank is detachably connected to the lower end of the grain hopper.

Therefore, since the lower part of the auxiliary tank is formed by the lower tank part having a non-deformable structure, it is possible to easily attach and remove the auxiliary tank, and the upper part of the auxiliary tank is formed by the upper tank part having a foldable structure. An auxiliary tank can be easily connected to the grain hopper, and the capacity of the auxiliary tank can be increased and the auxiliary tank support structure can be simplified compared to the conventional method.

It is configured to continuously harvest and thresh grain culms.

As shown in FIGS. 3 to 5, a paddy auxiliary tank 28, which is a lower grain tank, is mounted on the paddy holder 27 below the grain hopper 18, and the hopper 18 and the auxiliary tank are arranged in upper and lower layers. 28 is disposed, and the paddy discharge ports 29, 29 of the hopper 18 are configured to face the inside upper part of the auxiliary tank 28.

Further, the auxiliary tank 28 is a lower tank section 28.
a is made of a rigid iron plate, and the upper tank part 28b is made of stretchable cloth or the like.The lower and upper tank parts 28a and 28b are integrally connected via bolts 30, and the upper end of the upper tank part 28 is made of It is fixed to the hook metal fitting 32 via the hanging metal fitting 31,
Left and right hooks 33, 3 fixed to the hopper 18
4 to hook the metal fittings 32 to these hoppers 1.
8 and the auxiliary tank 28 form a grain tank.

The auxiliary tank 28 is detachably attached to the paddy holder 27 via a set bolt 35, a sliding body 36, a guide rail 37, etc.
A grain discharge spring conveyor 39 is horizontally mounted on the trough-like bottom 38 of the auxiliary tank 28, and this conveyor 39
A flexible discharge tube 40 is inserted through the feeding end of the tube to extend outside the machine.

On the other hand, the central chevron-shaped gutter portion 41 of the grain flow down gutter 18a, which is the funnel portion of the hopper 18, is formed to be removable, and the chevron-shaped gutter portion can be slid freely on a guide rail 42 installed on the lower side of the grain flow gutter 18. 4
When carrying out grain tank work using the auxiliary tank 28 by guiding and supporting the grain tank 1, by sliding the gutter section 41 outward to the right and removing it, the paddy auxiliary discharge port 43 opened at the center of the downstream gutter 18a can be removed. The grains in the hopper 18 are also configured to fall into the auxiliary tank 28. As is clear from the above, in the grain tank device of a combine that is provided with the grain hopper 18 into which grains are placed and performs bagging work by taking out the grains from the grain hopper 18 through the funnel part 18a, the lower tank part 28a
and the auxiliary tank 28 which can see the upper tank part 28b.
is removably provided below the grain hopper 18,
The lower tank part 28 has a structure that is less deformable than the distance between the lower end of the grain hopper 18 and the installation surface of the auxiliary tank 28.
In addition to configuring the vertical width of a to be small, the lower end of the upper tank part 28b having a freely foldable structure is integrally connected to the upper end of the lower tank part 28a, and the upper end of the upper tank part 28b is connected to the lower end of the grain hopper 18. It is detachably connected to the.

In addition, 44 is an opening/closing shutter provided at the discharge port 29, 45 is an input pulley for rotating the spring conveyor 39 by the driving force of the engine 17, and 46

This embodiment is constructed as described above, and when the reaping work area is large and the grains are directly transported to a transport vehicle, an auxiliary tank 28 is mounted below the grain hopper 18, and the upper and lower The work is performed with the grains arranged in two layers, and during this work, the grains introduced into the hopper 18 from the grain lifting cylinder 19 are initially stored in the auxiliary tank 28 through the discharge ports 29, 29. After the tank 28 is full, the hopper 18 at the top is sequentially stored, and when both the hopper 18 and the tank 28 are full and the sensor 46 detects this, the reaping operation is interrupted. However, these hopper 18 and tank 28
The grains inside are transported to a transport vehicle or the like via the conveyor 39.

On the other hand, when the reaping work area is small and the amount of grain to be taken out is small, the hook fitting 32 of the auxiliary tank 28 is removed from the hooks 33 and 34 as shown in the imaginary line in Fig. 4. The tank portion 28b is contracted onto the lower tank portion 28a, and then the bolt 35 is removed and the slider 36 is slid along the guide rail 37 to remove the auxiliary tank 28 from paddy. It is removed from the machine from the pedestal 27, and then the grains are taken out using a paddy bag or the like.

When the auxiliary tank 28 is used together with the grain hopper 18 as a grain tank, the upper tank portion 28b of the auxiliary tank 28 freely expands and contracts, so that it bulges out to the side of the fuselage. As the weight of each tank increases, the tank portion 28b can be formed into a free shape that adapts to the space volume of the upper region.

Moreover, by removing the gutter part 41 outside the machine in advance and opening the auxiliary discharge port 43 in the center of the downstream gutter 18a, this area A, which would conventionally be the surplus space area A.
It is possible to effectively increase the tank capacity of the hopper 18 and the auxiliary tank 28 by storing grains in the hopper 18 and the auxiliary tank 28, and by increasing the discharge ports 29 and 43, the grains can be stored uniformly in the auxiliary tank 28. be able to. Furthermore, by opening the auxiliary discharge port 43 in advance under working conditions such as grains with poor flow, high moisture content, or grains with many branches, the falling of the grains is facilitated and the grains are removed on the way. Problems such as poor grain flow or clogging are eliminated.

FIGS. 6 and 7 show another example of a modified structure, in which the entire grain flow gutter 18a, which is the funnel part of the hopper 18, is removably provided. The gutter 18a can be slid left and right on a guide rail 47 fixed to the inner wall.
When both ends are supported and the downflow gutter 18a is removed, the maximum capacity of grains is stored in the auxiliary tank 28, and the storage volume in the grain tank formed by the hopper 18 and the auxiliary tank 28 is The structure is designed to allow expansion and increase the amount of grain stored. In addition, when performing grain tank work using the hopper 18 and the tank 28, a hanging film 48 as shown in the imaginary line in FIG.
It may be configured to prevent grains from leaking from the gap between the tank 8 and the tank 28.

As is clear from the above embodiments, the present invention is a grain tank device for a combine harvester which is provided with a grain hopper 18 into which grains are placed, and which takes out grains from the grain hopper 18 through a funnel part 18a and performs bagging work. In this case, an auxiliary tank 28 including a lower tank part 28a and an upper tank part 28b is detachably provided below the grain hopper 18, and the lower tank has a non-deformable structure than the distance between the lower end of the grain hopper 18 and the installation surface of the auxiliary tank 28. The vertical width of the section 28a is made small, and the lower end of the upper tank section 28b, which has a foldable structure, is integrally connected to the upper end of the lower tank section 28a, and the upper end of the upper tank section 28b is connected to the lower end of the grain hopper 18. Since the lower part of the auxiliary tank 28 is formed by the lower tank part 28a with a non-deformable structure, the auxiliary tank 28 can be easily attached and removed, and the upper part of the auxiliary tank 28 can be easily attached and detached. Since the upper tank part 28b has a foldable structure, the auxiliary tank 28 can be easily connected to the grain hopper 18, and the capacity of the auxiliary tank 28 can be expanded and the support structure of the auxiliary tank 28 can be improved compared to the conventional structure.
