Opening and closing mechanism of grain discharge port

Abstract

The invention provides an opening and closing mechanism of a grain discharge port, which can prevent grains discharged by a grain unloading device from overflowing out of a bag when the grains are bagged. A gate (32) is provided so as to be rotatable between an open position and a closed position with the shutter shaft (36) as a fulcrum. When the gate (32) is in the open position, the grain discharge port (27) of the grain discharge device (9) is opened, and the grains conveyed from the grain tank (4) are discharged to the outside of the harvester through the grain discharge port (27) by the operation of the grain discharge device (9). When the gate (32) is closed from the open position to the closed position after the operation of the grain discharge device (9) is stopped, the grain discharge port (27) of the grain discharge device (9) is closed, and the discharge of grain from the grain discharge port (27) is stopped. The gate (32) is manually opened and closed (moved to an open position and a closed position).

Description

technical field [0001] The present invention relates to an opening and closing mechanism for opening and closing a grain discharge port of a grain unloading device mounted on a combine harvester. Background technique [0002] In the combine harvester, the stalk root of the grain stalk planted in the field is harvested by the harvesting device, and the harvested grain stalk is transported from the harvesting device to the threshing device, and the grain stalk is threshed by the threshing device, and the grain stalk is detached from the grain stalk. grains collected in the grain bin. The grain box is connected with a grain unloading device, and the grains collected by the grain box can be discharged out of the machine through the unloading device. [0003] The gate which opens and closes the grain discharge port of grain is provided in the front-end|tip part of a grain unloading device. The gate is supported on a gate shaft perpendicular to the grain conveying direction of t...

AI Technical Summary

Problems solved by technology

However, in the structure where the gate is opened and closed electrically, the gate cannot be opened and closed by a small amount, and a large amount of grains are discharged every time the gate is opened and closed, and the grains may spill out of the bag.
