DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine paddy bag supporting structure.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Laid-Open Publication No. 4-77743, a paddy bag supporting structure of a combine includes a paddle supporting rod having a pair of bag supporting rods for suspending and supporting both ends of a paddy bag. The paddle is supported so as to be rotatable around the horizontal axis with respect to the machine body, and the paddle supporting rod is supported in a horizontal posture from below via a spring.

[0003]

According to the above-mentioned conventional structure, when a full paddy bag is sunk under the discharge cylinder of the Glen hopper and removed from the paddle supporting rod, the tip of the paddle supporting rod is spring-loaded. Although there is an advantage that the rice sack is easily taken out by rotating downward against the urging force of the above, there is a disadvantage that the rice sack comes off from the tip of the rice sack support rod due to the vertical movement of the rice sack support rod due to the vibration of the body. In order to avoid this, if the urging force of the spring is increased, if the tip of the paddle supporting rod is pushed down and the paddle is taken out against the urging force of the spring, there is an inconvenience that the paddy bag is difficult to take out and there is room for improvement. was there.

The present invention makes it easy to take out a full paddy bag from the paddle supporting rod when the paddle bag is taken out from the paddle supporting rod. The purpose is to do.

[0005]

According to the first aspect of the present invention, at least one of a pair of bag supporting rods penetrating through the upper ends of the paddy bag and supporting the paddle is suspended around the horizontal axis with respect to the body. The operation lever is pivotally supported so as to be vertically rotatable, and an operation lever is attached so as to be vertically rotatable around a horizontal axis different from the rotation axis of the bag support rod. The integrated fixed arm is engaged and connected via a connecting pin,
The bag support rod can be fixed and maintained in a suspending action posture by three points of a rotation support point of the bag support rod, a rotation support point of the operation lever, and a connection point of the operation lever and the fixed arm. A pin hole of a connecting pin that engages and connects the operating lever and the operating lever, and a flexible portion for rotating the bag supporting rod downward by a certain range in accordance with the downward operating operation of the operating lever; An urging mechanism is provided for swinging the support rod back to the operating position. [Operation] According to this configuration, the bag support bar is fixed horizontally by the three-point tension by the rotation support point of the bag support rod, the rotation support point of the operation lever, and the connection point of the operation lever and the fixed arm, and the vibration of the machine body Up-and-down movement of the bag support bar is restricted. And when taking out the paddy bag, when the operation lever is pushed down, the restriction of the connecting pin by the vertical surface of the long hole in the interchange portion is released, the connecting pin moves in the horizontal direction, and the bag supporting rod is moved. As a result, the full bag can be taken out under the discharge cylinder of the Glen Hopper. [Effect] According to the first aspect of the present invention, the bag supporting rod does not move up and down due to the vibration of the airframe.
It is possible to prevent the paddy bag from unexpectedly coming out of the tip of the bag support bar due to the vibration of the body. In addition, when taking out a full bag, the tip of the bag support rod can be rotated downward by one-touch operation with the operation lever, and the full bag can be easily taken out by dipping under the discharge cylinder of the Glen Hopper. it can.

According to a second aspect of the present invention, there is provided a plurality of sets of paddle supporting rods each having a pair of bag supporting rods penetrating through the upper ends of the paddles and suspending and supporting them. The support rod is configured to be integrally operable. [Operation] According to this configuration, the same operation as the invention according to claim 1 can be performed, and a plurality of sets of paddy bag supporting rods can be integrally operated by one-touch operation of the operation lever. [Effects] According to the second aspect of the present invention, the above-mentioned effects of the first aspect of the invention are provided, and the operability can be improved as compared with a case where a plurality of sets of paddy bag supporting rods are separately operated.

According to a third aspect of the present invention, there are provided a plurality of sets of paddle supporting rods each having a pair of supporting rods for penetrating and suspending the upper ends of the paddy bags. The support rods are configured to be individually operable. [Operation] According to this configuration, the same operation as the invention according to claim 1 can be performed, and only the desired paddle supporting rod can be rotated downward. [Effect] According to the invention according to claim 3, the above-mentioned effect of the invention according to claim 1 is provided, and the paddles which are full as compared with a case where a plurality of sets of paddle supporting rods are integrally operated. Can be released sequentially.

According to the present invention, there are provided a plurality of sets of paddle supporting rods each having a pair of pad supporting rods penetrating through the upper ends of the paddles and suspending and supporting the paddles. Only one paddle supporting rod of the rods can be operated integrally. [Action] When a filled paddy bag is discharged to a predetermined location, if the release point is far away, the filled paddy bag is hung on one of the bag support bars in a horizontally fixed posture. The next paddy bag can be set. [Effect] According to the invention according to claim 4, the above-mentioned effect of the invention according to claim 1 is obtained, and the filled rice sack is suspended on one of the bag support bars in a horizontally fixed posture and moved to a predetermined position. Can be released.
