Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bundling device for bundling stalks mounted on, for example, a mowing bundling machine or a combine.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Laid-Open No. 8-5 discloses a binding device.
Like the one disclosed in Japanese Patent No. 1843, the string guide plate (reference numeral 6) is attached to the string knot portion of the binding device by screwing the upper and lower parts thereof with a plurality of vertical bolts.

[0003]

By the way, the cord guide plate is a member that forms a binding space having a function as a partition for preventing the binding object from reaching the knot portion, in addition to the cord guiding function at the time of the knot. And is configured as a relatively large component. Therefore, the string guide plate is often removed at the time of inspecting and servicing the knot, for example, cleaning the string residue of the string holder at the knot or removing broken strings. However, since the moving members and mechanisms that move during binding operation are complicated above and below the string guide plate, and there is insufficient space, it is difficult to put in a bolt operation jig or human fingers at the bolt fastening point. Therefore, it is difficult to operate the attachment bolts of the string guide plate.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a binding device that allows easy operation of attaching and detaching the string guide plate without hindering the function of the binding device.

[Means for Solving the Problems]

(Structure) The bundling device according to claim 1 of the present invention can be freely inserted into and removed from the string guide plate located on one side of the bundling space and the fixing member of the string knot in the length direction of the bundling culm. setting only a plurality of positioning fitting portions such, in one of the positioning fitting portion, opposite the back to the side facing the binding space of the cord guide plate
On the surface side, the cord guide plate and the one side in the length direction of the united stem culm
Connects to the fixing member with a pin that fits in the length direction of the bundle stem
In addition, the other side of the positioning fitting part
And the back side opposite to the side of the string guide plate facing the binding space.
On the side, the string guide plate and the fixing member on the other side in the length direction of the bundled stem culm are pierced and connected by means of a retaining pin that is detachable from the outside of the device, and the direction of insertion and removal of the retaining pin is defined as follows. A characteristic configuration is that the direction is set along the moving direction in the binding space.

(Operation) According to the configuration of claim 1 of the present invention, when the cord guide plate is attached to and detached from the fixing member of the cord knot portion, the binding stem culm in the cord guide plate and the fixing portion is attached. Is attached and detached at a plurality of positioning fitting portions that can be fitted to and removed from each other in the longitudinal direction of the cord.
On the back side of the pair, one side of this string guide plate and the length direction of the bundling culm
The fixing member of the unit is connected with a pin that fits in the length direction of the bundling culm.
And the other side of the positioning fitting part.
And the back side opposite to the side of the string guide plate facing the binding space.
Then, the cord guide plate and the fixing member are fixed by a detachable retaining pin from the outside of the device on the other side in the length direction of the cord guide plate and the bundling culm . And the string guide plate
The locating fitting on one side in the length direction of the bundled stem culm
Connect by fitting pins in the length direction of the
Since the insertion direction of the retaining pin is set to the direction along the moving direction of the binding stem culm in the binding space,
It is possible to manually attach and detach the retaining pin in a direction along the moving direction of the bundling stem culm in the bundling space without the parts of the string knotting portion being relatively obstructive. For this reason, the work for attaching and detaching the bundled stems to the fixing portion of the string guide plate in the length direction and the operation of the bundled stems for the bundled stems
The cord guide plate can be attached / detached to / from the fixing portion by a simple and small number of works of manually attaching / detaching the retaining pin through a relatively wide space along the moving direction in the binding space .

(Effect) Therefore, according to the structure according to claim 1 of the present invention, the work of attaching and detaching the bundling culm to the fixing portion of the string guide plate in the length direction and the manual retaining through the relatively wide space are prevented. Since it is possible to attach and detach the pin to and from the fixed portion of the string guide plate in a state in which the pin is easily attached and detached and the number of work steps is reduced, the workability can be greatly improved.

(Structure) A bundling device according to a second aspect of the present invention is the binding device according to the first aspect, wherein the positioning fitting portions are provided at three positions, and the positioning fitting portions are arranged in the stem-culm length direction, It is characterized in that they are distributed and arranged in the moving direction of the stems.

(Operation) According to the second aspect of the present invention, since the positioning fitting portions are three-dimensionally dispersed, the fixed support of the string guide plate is also high in strength. It has become a thing.

(Effect) Therefore, according to the structure of claim 2 of the present invention, the number of fitting points is set to a small number of three, and the structure is simple, but the durability is increased and the cord is improved. The guide plate can be fixedly supported.
