Abstract

PURPOSE:To reduce the amount of a tank projected to the right-hand side of a body of machine during removal and to readily open a tank-fixed part even at a narrow spot by installing a support shaft for horizontally rotating a grain tank at a specific position. CONSTITUTION:A support shaft 17 for horizontally rotating a grain tank 15 is installed at the rear of a body of machine at the side of furnishing of a feed chain 5 at the opposite side to a tank storage position of a base 3. A wide operation space can be formed on the base of the furnishing part of the tank in a state wherein the front of the tank apart from the support shaft is maintained closely to the base.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine equipped with a grain tank for storing harvested grains.

[0002]

2. Description of the Related Art Conventionally, there has been a technique in which a grain tank is horizontally rotated about a fulcrum shaft and is withdrawn from the machine.

[0003]

In the prior art described above, the tank is rotated outward rightward about the fulcrum shaft provided close to the grain tank. There is a problem in that the lateral balance of the machine body is easily lost in a weak field, and that the tank cannot be easily taken out in a narrow place, for example, in a soft field.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, in a combine in which a fulcrum shaft for horizontally rotating a grain tank is provided and the tank is supported so as to be able to retreat out of the machine, the side opposite to the tank storage position of the machine base. With the fulcrum shaft provided at the rear of the machine on the feed chain mounting side, since the tank is pulled out backward on the machine base, it is possible to easily reduce the amount of overhang of the tank to the right side of the machine at the time of removal, It is possible to prevent the left and right balance of the aircraft from being disturbed in soft fields, etc., and to easily open the tank mounting part even in a narrow place, and keep the tank front part away from the fulcrum axis close to the machine base. Thus, a work space wider than before can be easily formed on the machine base of the tank mounting portion.

Further, in a combine provided with a fulcrum shaft for horizontally rotating the grain tank and supporting the tank so as to be able to retreat out of the machine, the fulcrum is provided at the rear of the body on the feed chain mounting side opposite to the tank storage position of the machine base. With a shaft,
The fulcrum shaft is formed by a part of the discharge auger for taking out the grains of the grain tank, and the tank supporting structure can be simplified at a low cost by using the lower transverse feed part of the discharge auger. It is possible to drive the discharge auger on the mounting side, eliminate the conventional threshing and drive system between tanks to simplify maintenance, etc., and improve the left and right balance of the aircraft by the left and right arrangement of the tank and discharge auger. Etc. can be easily achieved.
