Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention collects grain bundles sent laterally outward from a binding device, and opens a door when the collected grain bundles reach a predetermined amount. The present invention relates to a grain culm bundle collecting and discharging device for a binder configured to discharge collected grain culm bundles, and more particularly to a technique for detecting that the collected grain culm bundles have reached a predetermined amount.

[Conventional technology]

Conventionally, as a technique for detecting that the grain culm bundles collected by the grain culm bundle collecting and discharging device (hereinafter referred to as the discharging device) having the above-mentioned configuration has reached a predetermined amount, for example, 1
As shown in Publication No. 07231, operation 1 of the binding device
Each time, rotate the claw wheel by the angle of one claw,
The tip of the ratchet arm that rotates the claw wheel fits into the deep grooves formed at predetermined intervals in the claw wheel, and the posture of the ratchet arm changes, so that the collected grain culm bundle reaches a predetermined amount. Some devices are configured to detect when the target has been reached.

[Problem that the invention seeks to solve]

However, with the detection technology configured as in the above cited example, there are problems in that there are many moving parts and the structure tends to be complicated because the wheel with claws is rotated using a ratchet-type structure. Simplification is desired.

An object of the present invention is to construct, as simply as possible, a structure capable of detecting when a predetermined amount of collected grain bundles has been reached through reasonable modification.

[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 by a predetermined amount every time the binding operation of the binding device is performed.
An endless rotating band having a projection formed thereon is wound around the wheel body, and a mechanism is provided for opening the door by the contact of the projection so that the door is opened every predetermined number of times of binding by the contact action of the projection. , there is a point provided at a position that overlaps with the locus of movement of the protrusion, and its action and effect 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 a predetermined number of times per binding operation, and as a result, the endless chain (22)
The protrusion (43) provided at the cam (28) reaches a position where it presses the abutment cam (28) every predetermined number of times.

Further, in this structure, the abutting cam (28) is pressed by the power from the input shaft (17) to unlock the locking mechanism (28) that maintains the closed state of the door (14), and the door =
(14) The opening operation is performed.

In other words, by forming protrusions on the endless rotating band that is fed a predetermined number of times each time the binding operation is performed, it is possible to detect that the binding operation has been performed a predetermined number of times.

〔Effect of the invention〕

Therefore, by relatively minor modification of forming protrusions on the endless rotating belt, a structure that can detect that the grain culm bundle has been rotated a predetermined number of times has been obtained.

In addition, in this configuration, since projections are formed on the endless rotating belt, the distance between the projections can be increased compared to, for example, a structure in which projections are formed on the transponder, so that the grain culm bundle sent out from the binding device can be It also has the effect of being able to count even a relatively large number of objects.
