Description

[Detailed Description of the Invention] In the present invention, when the string from the holder that holds one end of the binding string is locked to the string receiving protrusion 11,
The present invention relates to a stem culm binding device configured to knot a binding string by the action of a knotting bill 7.

If a knotted string breaks due to a tying error and the string remains at the tip of the knot building, the tying error will occur unless the machine is stopped each time a tying error occurs and the string remaining at the tip of the knot building is removed. This occurs continuously, and the broken string wraps around the nodal building multiple times, leading to serious trouble. In other words, if a broken string wraps around the knot building in an abnormal manner, an excessive load will be applied between it and the string receiving protrusion, causing problems such as deformation or damage to the tip of the knot building. was deformed abnormally, and even after removing the string, this was a factor that led to the next bundling error.

In contrast, the present invention is characterized in that the string receiving protrusion is configured to break due to overload caused by abnormal winding of the string around the knot building, thereby preventing damage to the knot building. By avoiding this problem and replacing it with a new string receiving protrusion, it has become possible to avoid the continuation of bundling errors.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Fig. 1 shows a stem culm binding device for tying waste straw after threshing and discharging it into the field.
The tying string is provided with a string supply section 2 on the lower side and a knot section 3 on the upper side. The waste straw is fed into the binding passage 1 and collected in a state where it is received by the T protrusion 6 provided at After that, the knot bill 7 is actuated in synchronization with the holder 5 to make the knot, and then the discharge arm 8 is actuated to discharge the tied stem culm.

When supplying the binding string from the string supply section 2 to the knotted part 3, a guide groove 10 is bored in a string guide plate (platform) 9 provided above the binding passageway 1 and close to the knotted part 3, and a guide groove 10 is formed in the string guide plate (platform) 9 to guide the knotted part. The needle 4 is configured to move forward and backward toward the nodule portion 3 through the groove 10,
Then, a string receiving protrusion 11 was removably provided on the string guide plate 9 across the guide groove 10 via a tightening fixture 12, and the string was wound around the bundle of bundles of stems and culms and supplied to the holder 5 side. In this state, the string is received and held at a predetermined position, and the knot bill 7 is configured to properly lock the string.

The string receiving protrusion 11 receives and holds the binding string on its free end side, and when the binding string is wrapped around the building 7 in an abnormal manner, the string receiving protrusion 11 receives and holds the binding string. It is constructed so that it breaks in the middle. In the embodiment, on the side of the string receiving protrusion 11 facing the building 7, a concave groove 13 is formed in the width direction in the middle of the protrusion 11 to reduce the wall thickness, and the strap is configured to break from that part. has been done.

In addition, since the concave groove 13 of the string receiving projection 11 is provided on the opposite side of the building 7, if the string wrapped around the building does not come out and accumulates, it will be subjected to the straining action as the building rotates. It also has the effect of making it easier to come out through the groove.

In summary, in the case of the present invention, the string receiving protrusion 11 is configured to break due to overload caused by abnormal winding of the string around the knot building 7, so that damage to the expensive knot building can be avoided. prevent it from happening,
It is economical because it is sufficient to replace the string receiving protrusion, which can be done at a relatively low cost, and there is an advantage that troubles caused by the string getting caught can be easily solved.
