Abstract

PURPOSE:To prevent leakage of rice hulls and scattering of grain granule by sealing a joint part between the side plate of grain tank and the upper edge of quantity increasing tank with a flexible member suspended in a hung state with laying the lower end downward. CONSTITUTION:In a grain tank 9 wherein a quantity increasing tank 12 laid at the side of the grain tank 9 is equipped in such a way that the quantity increasing tank is revolved around a shaft at the lower part and can be taken in and out from the tank 9 and a ceiling plate 13 of the quantity increasing tank 12 can be folded and stored, a joint part (hinge part 15) between the side plate of the grain tank 9 and the upper edge of the quantity increasing tank 12 is sealed with a flexible member 18 such as rubber hanging sustained in a hung state downward from an upper position corresponding to the joint part to surely prevent leakage of rice hulls.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a grain tank for a combine harvester that receives and stores processed grain from a threshing section. [Prior art and the problem to be solved by the invention] The capacity of the tank can be increased by configuring an increase tank attached to the side of the grain tank to be able to be moved in and out of the tank by rotating around an axis on the lower end side. Techniques designed to achieve this are already known. Also, in this divine thing, fold the top plate of the increase tank.
Techniques for composing J-Noh are also known.

However, in such a structure, since the joints of the nki tanks were connected by butterfly plates or the like, paddy leakage occurred from the gaps between the joints.

The present invention aims to prevent the occurrence of such paddy leakage, and has taken the following technical measures.

[Means to solve the problem]

That is, the technical means of the present invention is to attach the sales increase tank 12 attached to the side of the grain tank 9 so that it can be freely inserted into and taken out of the tank by rotating around the axis P on the end side. In a grain tank that is constructed with a large plate 13 for storage, from above the part corresponding to the joint between the side plate of the grain tank 9 and the upper edge of the tank 12, and , is characterized in that the NFL9 member 18 is suspended from the Glentan 99 side in the -do direction. [Effects of the Invention] Therefore, according to the first aspect of the invention, the joint between the grain tank and the expansion tank can be sealed by the μf flexible member, so that leakage of paddy can be reliably prevented.

In addition, this seal structure is a flexible member and is hung in a suspended state with the end facing downward, so that the grains thrown in from the throwing L1 of the grain lifting cylinder are not affected. The impact is alleviated and scattering can be prevented.
Moreover, the number of stitches fed into the increase tank can also be increased.

〔Example〕

Hereinafter, an embodiment of the invention will be described based on the drawings. The upper part is a reaping section, the front end is provided with a weeding device R2, 2, and behind it is a pulling device 4 with a lifting lug 3 and a reaping device i+. There will be a fee of ¥5. 6 is a conveying device, 7 is a grain culm {1 (feeding device, 8
is a threshing device, and a grain tank 9 is mounted on one side of it. 10 is the operating point.

Grain that has been threshed by a threshing device is stored in the grain tank 9 via a grain lifting cylinder l1.

The increase tank 12 has an outer plate 12a, left and right side plates 12b,
12b and the top plate 13, the grain tank 9
The top plate 13 is attached to the side of the tank 9 by moving concavely around the axis P on the lower end side and attached to the flower tank 9, and the top plate 13 has a pair of plates attached to the lower side by a hinge 14 in the center. It is constructed so that it can be bent, and has a pair of hinges 15, 1 at both ends.
At 6, it is attached to the upper edge of the increase tank 12 and the side plate 17 of the grain tank 9, and folded to form a storage structure. Then, from above the part corresponding to the joint (hinge 15 part) between the side plate of the grain tank 9 and the upper end edge of the reforged tank 12, l1. Side plate 17 on the Glen tank 9 side
An lIf flexible member 18 like a rubber sag is suspended downward.

In the state shown in FIG. 2, when the grain tank 9 and the bulking tank 12 are filled with grains, the hf flexible member 18 is bent toward the panoramic tank 12, and the grain tank 9 and bulking tank 12 are bent. This will seal the joint.

Reference numeral 19 denotes a seal provided at the sliding portion between the left and right side plates 12b of the increase tank 12 and the side frame 20 of the grain tank 9, and the seal 19 is formed in a structure that can be inserted from above into the insertion groove 21 as in the fourth example. ing.

The figures show one embodiment of the present invention. Fig. 1 is a Nl side view of the combine, Fig. 2 is a cross section of the grain tank (lIi), Fig. 3 is a sectional view of the main parts, and Fig. 4 is a cross-sectional view of the main part. FIG.

Claims (1)

[Claims] (1) Expansion tank 12 attached to the side of grain tank 9
In the grain tank, the side plate of the grain tank 9 and the volume increaser tank are installed so that it can be rotated around an axis P on the lower end side to be freely put in and taken out of the tank, and the top plate 13 of the volume increase tank 12 can be folded and stored. A grain tank characterized in that a flexible member 18 is provided in a suspended state from above a portion corresponding to the joint portion with the upper end edge of the grain tank 12 and from the grain tank 9 side downwardly. .
