Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is mainly used mounted on a mobile threshing machine such as a combine harvester, and more specifically, a grain storage bag is inserted and supported by a pair of bag hanging support rods, and a grain storage bag is installed at the bottom of a hopper. a bag feeding mechanism that automatically feeds and moves the grains below the grain outlet, and a mechanism that automatically fills the storage bag with grains below the outlet;
This invention relates to an automatic bagging device for grains, which is equipped with a locking arm that locks a slider of a fastener provided at the opening edge of a storage bag and moves in a seven-fastener closing direction after grain filling processing.

Conventionally, a sensor for detecting completion of fastener closing, which detects whether the fastener has been closed by the locking arm, has been provided to detect the locking arm.

The disadvantage of the conventional method is that the sensing target of the sensor is the locking arm, so even if the fastener is not closed,
The locking arm is sensed as being closed when the locking arm moves in the zipper closing direction.

An object of the present invention is to provide a system that can more reliably detect the closing action of a zipper by appropriately selecting the object to be sensed by the sensor.

The characteristic configuration of the present invention is that a sensor for detecting the completion of zipper closing is provided to detect whether or not the slider is in the closed position, and its function and effect are as follows.

In other words, by selecting the slider that controls the opening/closing operation of the zipper as the sensing target of the sensor, it is possible to more accurately detect the completion of zipper closing compared to the conventional configuration that uses indirect sensing with the locking arm as the sensing target. can.

Therefore, by simply changing the sensing target of the sensor, sensing errors can be significantly reduced compared to the conventional configuration, and automatic bagging operations can now be carried out more smoothly.

Embodiments of the present invention will be described below based on the drawings.

Below the hopper (8) in which the grains are stored, a pair of left and right support rods for hanging bags (+41 l +4) are installed and supported as rotating shafts that can rotate around their axes, and these rotating support rods (4) A grain storage bag (3) having hanging support eyelets +211 and +21 attached to both ends in the opening width direction near the bag opening edge +11 is inserted and supported, and is installed at the bottom of the hopper (8). The bags are automatically fed and moved by the bag feeding mechanism (2υ) below the grain discharge port (5).

This feed-out bag (3) is automatically filled by a filling mechanism (22), and is automatically closed by a mechanism for closing a zipper bar provided at the bag opening edge [1], thereby constructing an automatic grain bagging device. do.

The bag feeding mechanism (21) for the bag (3) will be described in detail.
