Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Glen tank which is a resin molded product mounted on a combine or the like.

[0002]

2. Description of the Related Art Conventionally, a Glen tank has been constructed by blow molding into a tank shape.

[0003]

However, according to the above-mentioned conventional technique, since the Glen tank is constructed by blow molding into a tank shape, when the tank becomes large and deep, the resin to each part is Wrapping around became worse,
Uneven thickness was likely to occur and it was difficult to make.

An object of the present invention is to provide a Glen tank which is easy to make even if it is large.

[0005]

A Glen tank according to the present invention according to claim 1 is characterized in that it is a resin-molded Glen tank in which divided tank portions divided in the circumferential direction are connected by a thin hinge portion. The point is that it is molded.

A feature of the Glen tank according to the present invention according to claim 2 is that in the Glen tank according to the present invention according to claim 1, a concave portion and a convex portion which are fitted to each other are formed on the abutting surfaces of the divided tank portions. There is a point.

A feature of the Glen tank according to the present invention according to claim 3 is that in the Glen tank according to the present invention according to claims 1 and 2, the abutting surfaces of the divided tank portions are adhered or welded to each other.

A feature of the Glen tank according to the present invention according to claim 4 is that the Glen tank according to the present invention according to claims 1 and 2 is characterized in that a connecting member for connecting and disconnecting the abutting parts of the divided tank parts is detachable. The point is that it is provided.

A feature of the grain tank according to the present invention according to claim 5 is that the divided tank portion is blow-molded in the grain tank according to the present invention according to claims 1, 2, 3 and 4 above. .

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, in a combine, a mowing section 2 is movably connected to a front portion of a machine frame provided with a crawler traveling device 1, and the mowing section 2 is connected to the machine frame. The threshing unit 3 for threshing the harvested culm, the boarding operation unit 4, and the Glen tank 5 for storing the threshing grains are mounted. Reference numeral 6 in FIGS. 1 and 2 denotes a lifting conveyor for lifting and feeding the threshed grain (first product) from the threshing unit 3 to the Glen tank 5, and 7 taking out stored grains from the lower portion of the Glen tank 5. It is an unloader that discharges.

As shown in FIG. 2, the Glen tank 5 comprises a lower hopper portion 8 and a tank body 9 connected to the upper portion of the lower hopper portion 8 so as to communicate therewith.

Inside the lower hopper section 8 is arranged a screw conveyor 10 for supplying the stored grain to the unloader 7.

The tank body 9 is a resin-molded product, and as shown in FIG. 3, the divided tank portions 9A and 9B divided in the circumferential direction are blow-molded in a state where they are connected by a thin hinge portion 9C. As shown in FIG.
The concave portion 9a and the convex portion 9b which are fitted to each other on the abutting surface of B
As shown in FIG. 4, it is formed into a tank shape by folding with a thin hinge 9C, and the abutting surfaces are adhered or welded to each other. The concave portion 9a and the convex portion 9b may be either continuous in the vertical direction or intermittent.

[Another Embodiment] In the above embodiment, the Glen tank 5 is constructed by adhering or welding the abutting surfaces of the divided tank portions 9A and 9B, but as shown in FIG.
It may be carried out by providing a connecting member 11 capable of connecting and disconnecting the abutting parts of the divided tank parts 9A and 9B. The connecting member 11 uses the bolts 12 to divide the tank portion 9A,
9B is connected.

In the above embodiment, the tank body 9 is a blow molded product, but the tank body 9 may be a vacuum molded product.

[0016]

[Effects of the Invention] The divided tank portions divided in the circumferential direction are formed by blow molding with the thin hinge portions connected, and the divided tank portions are abutted by being folded at the thin hinge portions, and the abutting surfaces are bonded together in that state. Or by welding,
Since the Glen tank is constructed by connecting with the connecting member, the divided tank section is shallow for the size of the Glen tank, and it is easy for the resin to wrap around each section during molding, resulting in uneven thickness. Can be suppressed. Therefore, it has become possible to provide a Glen tank that is easy to manufacture even if it is large.

In particular, when a concave portion and a convex portion that are fitted to each other are formed on the abutting surfaces of the divided tank portions, the abutting surfaces can be made with high precision, and the divided tanks are abutted to each other to form a Glen tank. While configuring
The Glen tank can be made highly accurate.

Further, when the abutting parts of the divided tank parts are connected by a connecting member, the connection between the connecting members is released and the divided tank parts are opened with the thin hinge part as a fulcrum to open the inside of the Glen tank. Since it can be opened, maintenance such as cleaning the inside of the Glen tank can be easily performed.
