[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin grain tank mounted on a harvester such as a combine harvester.

[0002]

2. Description of the Related Art Conventionally, grain tanks mounted on harvesters such as combine harvesters are required to be lightweight, strong and inexpensive. Therefore, in order to meet this demand, resin products have been proposed, and JP-A-61-2
As disclosed in Japanese Patent No. 1032, a detachable bag has been devised that is lightweight, inexpensive, and convenient for maintenance work.

[0003]

However, although these conventional ones are lightweight and can be provided at a low cost, they cannot be said to have sufficient strength, resulting in tears and damages due to vibration or the like. Therefore, the present invention was developed for the purpose of providing a simple resin-made product that is strong and can withstand an external impact.

[0004]

[Means for Solving the Problems] As a first means of the present invention for achieving the above object, a grain from the threshing portion is mounted on a traveling platform adjacent to the threshing portion. A grain tank made of resin to be stored through a fried grain cylinder, the grain tank being blow-molded, and its parting line (molding position) is shifted to the outer side on the opposite side to the threshing section Formed from the outer part and the inner part, the thickness of the outer part is made thicker and the thickness of the inner part is made thinner, and a longitudinal groove is formed in the inner part, and the fried cylinder is provided in the groove. It is characterized in that it is configured so as to fit into the fitting state.
The means of the means, on the traveling platform, is equipped with a grain tank made of resin for storing the grain from the threshing portion and the threshing portion, and the grain in the grain tank is taken out by the discharge auger, The Glen tank is blow-molded so that its parting line (die-cutting position) part protrudes like a fin to the outside, and the fin part is rotatable around the vertical cylindrical part constituting the discharge auger. The present invention is characterized in that the Glen tank is attached to a support body and is mounted so as to be rotatable around a vertical cylindrical portion as an axis.

[0005]

Therefore, the grains from the threshing section are lifted by the lifting cylinder and put into and stored in the blow-molded resin-made Glen tank, and the stored grains are laterally fed at the bottom of the tank. It is taken over by the carry-out device to the vertical cylindrical portion of the discharge auger, lifted, and then discharged to a proper place. In this case, in the case of the first means, since the parting line of the Glen tank is formed from the vertically divided outer and inner parts and the outer part is thickened, the obstacle is obstructed. There is no risk of damage even if it hits an object, etc. Also, since the inner part where there is no risk of hitting is thin, the weight is further reduced, but a groove is formed in the vertical direction and Since the fried-grain barrel into which the grains are lifted and charged is fitted into the groove, the strength of the inner portion is reinforced.

According to the second means, since the resin-made Glen tank has fins formed by projecting the parting line portion to the outside in a fin shape, the Glen tank has increased strength. Further, since the fin portion is attached to a support body which is rotatable around the vertical cylindrical portion of the discharge auger, the Glen tank is rotatable outward with the vertical cylindrical portion as an axis. It becomes possible to firmly attach to the support body without adding a bracket for supporting the Glen tank made of steel separately.
