Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention collects the culm bundles sent laterally outward from the binding device, and opens the door when the collected culm bundles reach a predetermined amount. Regarding the binder shell culm bundle collecting and discharging device configured to discharge the collected shell culm bundles, in detail, it detects that the collected shell culm bundles have reached a predetermined amount and operates the door to open and close. Regarding technology for

[Conventional technology]

Conventionally, as a technique for detecting that the collected culm bundles have reached a predetermined amount using the shell culm bundle collecting and discharging device (hereinafter abbreviated as the discharging device) having the above-mentioned configuration, for example, the technology disclosed in Utility Model Application Publication No. 1987- 1
As shown in Publication No. 07231, operation 1 of the binding device
Each rotation, the claw-equipped wheel is rotated by an angle corresponding to one claw, and 1. With a claw, the tip of the ratchet arm that rotates the wheel fits in, and by changing the posture of the ratchet arm, it detects that the collected culm bundle has reached a predetermined amount and also controls the door opening operation. I have one configured to start.

[Problem that the invention seeks to solve]

However, the discharge device configured as in the above cited example has a structure in which a wheel with a claw rotates in a ratchet structure, so there are many moving parts, and the structure tends to be complicated. It is hoped that this will become a reality.

An object of the present invention is to detect when a predetermined amount of collected culm bundles has been reached through rational modification, and to configure the structure as simply as possible to open and close the door.

[Means for solving problems]

A feature of the present invention is that, in the discharge device having the above configuration, a wheel is provided on the shaft that rotates a predetermined amount each time the binding device performs the binding operation, and an endless rotation band is wound around the wheel. A pair of protrusions adjacent to each other at an arbitrary interval along the movement direction are formed on the rotation band, and the pair of protrusions is arranged such that the door is opened and closed every predetermined number of times by the abutting action of the pair of protrusions. A mechanism that opens the door by contact with the protrusion on the lower side in the direction of movement of the endless rotation band and closes the door by contact with the protrusion on the next upper side is placed at a position that overlaps with the locus of movement of the protrusion. The functions and effects are as follows.

[For production]

For example, if the features of the present invention are configured as shown in FIG.
The input shaft (17
), the endless chain (
22) is fed by a predetermined amount, the first protrusion (43a) provided on the endless chain (22) presses the contact cam (28) and releases the closing lock, as shown in Fig. 5. ,
The door (14) is operated to the open position, and in this open state, the door (14) is set to the locked state.

Thereafter, when the next binding operation is started, the second protrusion (43b) provided on the endless chain (22) presses the abutting cam (28) to release the lock and release the 1-ar (14).
) is blocked by the biasing force of the spring (51).

[Effects of the invention] Therefore, by forming a pair of protrusions on the endless rotation band, a relatively simple structure was obtained in which the door is opened and closed every time the collected culm bundle reaches a predetermined amount. .
