Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine grain discharging device for discharging grains stored in a grain tank, particularly beans such as soybeans and adzuki beans, to the outside of the grain tank.

[0002]

2. Description of the Related Art Conventionally, as one form of combine, a mowing unit for cutting grain rods, a transport unit for transporting the grain rods cut by the harvesting unit to a threshing unit, and a grain rod transported by the transport unit. The threshing unit for threshing, the swing sorting unit for swing-sorting the grain threshed by the threshing unit, the grain tank for storing the grain sorted by the swing sorting unit, and the grain stored for the grain tank There is a machine equipped with a discharge section for discharging the spores outside the machine and a straw processing section for processing the straw discharged from the threshing section.

The discharge section for discharging the grains from the grain tank to the outside of the machine is composed of a horizontal feed auger for connecting the lower portion of the grain tank to each other, a vertical auger connected to the rear portion of the horizontal feed auger, and a vertical auger. It is composed of a discharge auger connected to the upper part, and a grain discharge port is formed at the tip of the discharge auger, and the grain is discharged from the grain discharge port to the outside of the machine.

However, when beans such as soybeans having soft grains are discharged by the discharge auger, the grains are easily damaged and dirt adheres to the surface of the grains to deteriorate the quality of the grains. There was a problem. Therefore, conventionally, for beans such as soybeans, the grain is conveyed by a bucket conveyor and discharged, or discharged by a bagging device to prevent the grain from being soiled or polluted. However, since the delivery height of the bucket conveyor is limited in the discharge by the bucket conveyor, it is difficult to cope with the case where the transportation height of the grain is high, such as a container on a truck. In addition, when discharging by the bagging device, the grain bag in the bagging device is packed by discharging the grain from the discharge port of the Glen tank, but since the grain bag cannot be so large, it is divided into many bags. Since it has to be packed in bags, there is a problem in that bagging work and transportation work take time and labor, and work efficiency is poor.

[0005]

Therefore, the present invention has been made in view of the problems of the above-mentioned prior art, and the grains are directly discharged from the grain tank to damage the grains. It is an object of the present invention to provide a combine grain discharging apparatus that prevents the deterioration of quality by preventing soiling and stains and efficiently discharges grains.

[0006]

In order to achieve the above object, the combine grain discharging apparatus of the present invention has the following configuration. That is, in a combine equipped with a grain tank that stores grains that have been threshed by the threshing unit and a grain discharging device that has a discharge auger that discharges the grains from the grain tank, an openable and closable discharge gate provided in the grain tank The opening / closing operation and the operation of stopping the operation of the discharge auger by disconnecting the auger clutch for connecting the power of the discharge auger are interlocked with each other.

Here, during the grain discharge operation, the auger clutch may be connected after the discharge gate is opened.

When grain discharge is stopped, the discharge gate may be closed after disconnecting the auger clutch.

A control switch for controlling the operation of stopping the operation of the discharge auger and the opening / closing operation of the discharge gate may be provided in the driver's seat or in the vicinity of the discharge gate.
