Description

[Detailed description of the invention] 1. Industrial application field This invention is a combine harvester that continuously reaps grain culms and threshes grains, and is equipped with a grain lifter that takes out grain from the threshing part and a grain lifter installed on one side of the threshing part. a storage tank for storing grains; a vertical discharge conveyor whose lower end communicates with the tank and is fixed upright;
The present invention relates to an apparatus including a horizontal discharge conveyor that communicates with the upper end of the conveyor to deliver grains.

1. Prior Art Conventionally, there has been a technology in which a vehicle for transporting grain, etc. is equipped with a vertical discharge conveyor and a horizontal discharge conveyor, and the horizontal discharge conveyor is arranged to be able to move up and down and rotate horizontally.

1. Problems that the invention aims to solve: In the transport vehicle, the tank capacity for holding the grain can be easily increased arbitrarily compared to the combine harvester.
The horizontal discharge conveyor could be easily stored on the top of the tank, but since combine harvesters are mainly used for reaping and threshing, the shape and capacity of the tank mounted on the combine are regulated, and the tank can be of the desired capacity. It is difficult to prolong the time required for one harvest operation when the tank is full of grains, and furthermore, by providing the above-mentioned discharge conveyor close to the tank, the shape of the tank is further restricted. .

Further, in the prior art, the vertical and horizontal discharge conveyors are linearly connected and can be bent in the middle, or the vertical discharge conveyor is separated into upper and lower parts so that the upper part can be rotated horizontally, or the vertical discharge conveyor is Since the connecting portion between the lower end of the conveyor and the tank was made swingable, it was difficult to simplify the support structure of the vertical and horizontal discharge conveyors, and the drive means for horizontally rotating the horizontal discharge conveyor was complicated. There is a problem in that it is difficult to easily assemble and disassemble the conveyor during maintenance.

Means for Solving Problem 1 The present invention addresses the above-mentioned conventional problems, and the upper end of the grain lifting cylinder is opened approximately at the top of the tank mounted on the combine harvester body and into which grains are placed. Further, a conveyor joint member is horizontally rotatably provided on the outer upper surface of the tank lower than the upper end attachment device of the grain lifting cylinder of the tank, and a worm that engages with a worm gear fixed to the outer periphery of the joint member is connected to a handle near the driver's seat. At the same time, the upper end of the vertical discharge conveyor is communicated and supported by the joint member thereof, and the base end of the horizontal discharge conveyor is communicated and supported by the joint member so as to be able to rise and fall freely, and the horizontal discharge conveyor is provided on the upper surface of the threshing section lower than the upper surface of the tank. It is designed to be able to perform multiple functions.

However, in the present invention, by manufacturing and assembling the vertical and horizontal discharge conveyors and the joint members separately, the vertical discharge conveyor can be easily supported by fixing it closer to the tank than in the past. By interposing the joint member, the support structure of the vertical and horizontal discharge conveyors can be simplified and their assembly etc. can be facilitated, and by connecting the worm gear and the worm to the joint member, the horizontal discharge conveyor by the handle can be easily assembled. The horizontal rotation drive structure of the discharge conveyor can be simply obtained, the horizontal rotation operation of the handle at the height of the storage position of the horizontal discharge conveyor can be regulated by the contact between the conveyor and the tank, and the horizontal discharge conveyor can be raised. By giving priority to operation, the horizontal direction of the conveyor can be safely changed, and by forming at least the top surface of the tank higher than the base end of the lateral discharge conveyor, the height and width of the vehicle can be restricted as a special vehicle. The purpose of the present invention is to provide a grain storage device for a combine harvester, which allows the tank capacity to be easily expanded compared to the conventional combine harvester, facilitates handling, and improves the efficiency of harvesting operations.
