The horticultural binding machine 10 according to the present embodiment is used for attracting and binding work in crop cultivation, and as shown in FIGS. 1 to 3, a linearly formed elongated main handle 11 and a main handle A clincher arm 30 rotatably attached to the clincher arm 30 and an operation handle 50 rotatably attached to the clincher arm 30 are provided. As shown in FIG. 2, the clincher arm 30 is constantly urged by the tension spring 25, and is normally open to the main handle 11. Therefore, an opening C for inserting a bound object is provided between the tip portion 11a of the main handle 11 and the tip portion 30a of the clincher arm 30. By grasping the operation handle 50 and the main handle 11 from this state, as shown in FIG. 3, the clincher arm 30 rotates in the closing direction with respect to the main handle 11, and the opening C is closed to be bound. Things are bound together.

When bundling the objects to be bound, first, the handle is grasped and the clincher arm 30 is rotated with respect to the main handle 11 in the closing direction. As a result, the gripping operation of gripping the tape at the tip portion 30a of the clincher arm 30 is executed. After that, when the grip of the handle is released and the clincher arm 30 is rotated in the opening direction with respect to the main handle 11, the tip portion 30a of the clincher arm 30 and the tip portion 11a of the main handle 11 are held while the tape is gripped. Are separated from each other, and a tape is stretched between the clincher arm 30 and the main handle 11. A bound object such as a sapling or a branch is inserted from the outside of the tape stretched in this state, the handle is grasped again, and the clincher arm 30 is rotated in the closing direction with respect to the main handle 11. As a result, both ends of the tape loop that binds the objects to be bound are stapled together, and the tape is cut. In this way, the gripping operation is executed in the first gripping operation, and the binding operation is executed in the second gripping operation. Then, by alternately executing the gripping operation and the binding operation, the bound object can be bound. In the present embodiment, staples are used as a binding means for binding both ends of the tape loop, but the present invention is not limited to this, and both ends of the tape loop may be bonded by adhesion or welding. ..

As shown in FIG. 1 and the like, the main handle 11 is a rod-shaped member formed linearly, and is formed so that tapes and staples can be arranged along the longitudinal direction. A staple magazine 12, a tape guide 16, a tape magazine 20, and the like are attached to the main handle 11.

The staple magazine 12 is a long member for accommodating staples. As shown in FIG. 1 and the like, the staple magazine 12 is arranged along the longitudinal direction of the main handle 11, and can accommodate staples inside.

This staple driver is a plate fixed to the tip portion 11a of the main handle 11 so as to face the vicinity of the tip end of the staple magazine 12. This staple driver is formed with a width substantially the same as the width of the staple so that only one staple can be ejected. When the clincher arm 30 rotates to a state where it is completely closed with respect to the main handle 11, the staple magazine 12 is pressed in the direction of the staple driver, so that the staple driver enters the staple magazine 12 and enters the staple magazine 12. It is designed to launch the first staple. The stamped staples are clinched by a clincher 33, which will be described later, and both legs are bent so as to embrace the tape, thereby binding the ends of the overlapped tapes.

The tape magazine 20 is for accommodating the tape for bundling the objects to be bound, and is connected to the rear end of the main handle 11 as shown in FIG. 1 and the like. The tape magazine 20 can accommodate a tape wound in a reel shape, and has a lid that can be opened and closed to put in and take out the tape. The tape contained in the tape magazine 20 is pulled out along the main handle 11 to the tip end portion 11a of the main handle 11. The end of the tape pulled out to the tip 11a of the main handle 11 is held by the tape guide 16 described later.

As shown in FIG. 5, the tape guide 16 is arranged at the tip end portion 11a of the main handle 11. The tip of the tape held by the tape guide 16 faces the clincher arm 30. The tip of the tape held by the tape guide 16 in this way is gripped by the tape gripping device 35 of the clincher arm 30, which will be described later, and a required amount is drawn out.

As shown in FIG. 1 and the like, the clincher arm 30 is a member rotatably attached to the main handle 11 by a rotating shaft 31 provided near the rear end portion. The clincher arm 30 includes an arm portion 32 that extends curvedly in the direction of the tip portion 30a so that a C-shaped opening C can be formed between the clincher arm 30 and the main handle 11. Further, a clincher 33 and a tape gripping device 35 are attached to the clincher arm 30.

The clincher 33 is fixed to the tip portion 30a of the clincher arm 30 so as to face the tip of the staple driver described above.

As shown in FIG. 2, the operation handle 50 includes a base member 51 fixed to the main body of the gardening binding machine 10 and a cover material 55 that can be attached to and detached from the base member 51.

The base member 51 is a metal component that directly acts on the main handle 11 and the clincher arm 30. As shown in FIGS. 2 and 3, the base member 51 is rotatably attached to the clincher arm 30 about the rotation fulcrum 51a. A link portion 52 that engages with the main handle 11 is provided on one side when viewed from the rotation fulcrum 51a, and a lever operation portion 55c is provided on the other side when viewed from the rotation fulcrum 51a.

The link portion 52 is a portion that engages with the main handle 11 and serves as an action point of the lever. A hook 52c is formed at the tip of the link portion 52. The hook 52c can be engaged with the roller-shaped engaging portion 14 of the main handle 11. As shown in FIG. 2, by engaging the hook 52c with the roller-shaped engaging portion 14 at the innermost portion, the clincher arm 30 is maintained in a state of being opened at a predetermined angle with respect to the main handle 11. It has become. That is, the state in which the hook 52c is engaged with the roller-shaped engaging portion 14 at the innermost portion is the maximum opening state of the opening C.

When the operation handle 50 and the main handle 11 are squeezed from this state, the roller-shaped engaging portion 14 slides on the sliding surface 52a formed on the front surface of the link portion 52 as shown in FIG. As the sliding surface 52a slides along the roller-shaped engaging portion 14 in this way, the clincher arm 30 rotates in the closing direction with respect to the main handle 11. The inclination of the sliding surface 52a with which the roller-shaped engaging portion 14 is engaged is changed stepwise in order to reduce the operating load when the staples are launched. That is, by making the inclination of the sliding surface 52a when performing the binding operation larger than the inclination of the sliding surface 52a when performing the gripping operation, it is possible to obtain a larger force when performing the binding operation even with the same operating load. There is. By doing so, even a binding operation that requires a large force can be operated with a light operating load. Since the inclination of the sliding surface 52a changes in this way, a protrusion 52b is formed at a portion where the inclination of the sliding surface 52a changes.

The cover material 55 is a member that can be attached to and detached from the handle (base member 51). As shown in FIG. 1 and the like, the cover material 55 is attached so as to cover the base member 51. The cover material 55 includes a hook cover portion 55a and a lever operation portion 55c.

The hook cover portion 55a is a portion that covers the above-mentioned link portion 52 and the like.

Further, the lever operation unit 55c is a portion that the operator grasps when operating the operation handle 50. When the lever operating portion 55c is gripped in a direction approaching the main handle 11, the base member 51 rotates around the rotation fulcrum 51a, and the link portion 52 acts on the main handle 11. The main handle 11 and the clincher arm 30 rotate in the closing direction with each other.

By the way, the horticultural binding machine 10 according to the present embodiment includes an opening amount adjusting means 40 for adjusting the opening amount of the opening C. By adjusting the opening amount of the opening C by the opening amount adjusting means 40, when the binding diameter of the object to be bound is small, the maximum opening amount of the opening C is set to be small so that the amount of operation for grasping the handle can be increased. It becomes smaller and the work efficiency can be improved. Further, even an operator with a small hand can easily grip the handle by setting the maximum opening amount of the opening C to be small. As shown in FIGS. 4 and 5, the opening amount adjusting means 40 includes a regulating component 41 that can be attached to and detached from the horticultural binding machine 10.

As shown in FIG. 6, the regulated component 41 according to the present embodiment is a rod-shaped member that can be inserted and removed from the horticultural binding machine 10. As shown in FIG. 5, the restricting component 41 interferes with the operation handle 50 when attached to the horticultural binding machine 10 to restrict the movement of the operation handle 50.

Specifically, as shown in FIGS. 5 and 6, a mounting hole 42 for mounting the regulation component 41 is provided on the sheet metal constituting the main handle 11. By inserting the regulation component 41 into the mounting hole 42, the regulation component 41 is attached to the main handle 11 in parallel with the rotation shaft 31 of the handle. Both ends of the regulatory component 41 attached to the gardening binding machine 10 project from the attachment holes 42. On the other hand, at the tip of the hook 52c, receiving portions 43 that engage with each other near both ends of the regulation component 41 protruding from the mounting hole 42 are provided. The receiving portion 43 has a recessed shape so as to stably receive the regulation component 41.

When the opening C is opened from the closed state with the regulation component 41 attached, as shown in FIG. 5B, the receiving portion 43 is opened before the hook 52c and the roller-shaped engaging portion 14 are engaged with each other. And the regulation component 41 are engaged with each other, and the opening C cannot be opened any more. In this way, the regulation component 41 interferes with the operation handle 50, so that the opening amount of the opening C is regulated.

When the regulation component 41 is removed, as shown in FIG. 2, the opening C is opened until the hook 52c and the roller-shaped engaging portion 14 are engaged, so that the opening C is opened as compared with the case where the regulation component 41 is attached. The opening amount of the opening C becomes large. In other words, by attaching the regulation component 41, the opening amount of the opening C can be reduced.

Since the regulation component 41 according to the present embodiment has a round bar shape, it can be easily attached, but it may fall off just by being inserted into the attachment hole 42. Therefore, in the present embodiment, the regulation part 41 is attached to the gardening binding machine 10 inside the cover material 55. By doing so, the cover material 55 prevents the regulated component 41 from falling off.

When attaching the regulation component 41 in the present embodiment, the operation handle 50 is lifted upward to disengage the hook 52c from the roller-shaped engaging portion 14, so that the clincher arm 30 can rotate freely with respect to the main handle 11. .. If the clincher arm 30 is largely rotated with respect to the main handle 11 in this state, the mounting hole 42 is exposed, so that the regulation component 41 can be inserted into the mounting hole 42. After that, when the hook 52c is hooked on the roller-shaped engaging portion 14, both ends of the regulation component 41 face the cover material 55. As a result, the moving of the regulated component 41 in the axial direction is blocked by the cover material 55, so that the regulated component 41 is prevented from falling off.

Separately from this, the cover material 55 may be removed from the operation handle 50 so that the regulation component 41 can be attached to and detached from the mounting hole 42 with the cover material 55 removed.

Further, as shown in FIG. 5B, the regulation component 41 may be fixed by a fastener 44 such as an E-ring. In this way, the regulation component 41 can be further prevented from falling off, and the regulation component 41 falls off when the hook 52c is disengaged from the roller-shaped engaging portion 14 or when the cover material 55 is removed. Since it does not, the assembling property is improved.

In the above-described embodiment, the regulation component 41 is attached to the main handle 11, but the present invention is not limited to this, and the regulation component 41 may be attached to another location.

For example, as shown in FIG. 7, a mounting hole 42 for mounting the regulation component 41 may be provided in the sheet metal constituting the clincher arm 30. Then, the regulation component 41 may be inserted into the mounting hole 42 for mounting. Then, the operation handle 50 may be provided with a receiving portion 43 that engages with the regulation component 41. In this case, the regulation component 41 is attached to the clincher arm 30 in parallel with the rotation shaft 31 of the handle. Further, by engaging the regulating component 41 with the receiving portion 43 of the operation handle 50, the opening amount of the opening C can be regulated.

Further, in the above-described embodiment, the receiving portion 43 that engages with the regulation component 41 is provided on the operation handle 50, but the present invention is not limited to this, and the receiving portion 43 may be attached to another location.

For example, as shown in FIG. 8, the clincher arm 30 may be provided with a receiving portion 43 that engages with the regulation component 41. In the example shown in FIG. 8, the receiving portion 43 is formed by an arc-shaped elongated hole, and the regulating component 41 is attached to the main handle 11 so as to penetrate the elongated hole. In this way, the position and shape of the receiving portion 43 can be appropriately set.

In the above-described embodiment, the opening amount is adjusted in two stages, but the present invention is not limited to this, and if a plurality of mounting positions of the regulation component 41 are provided, the opening amount can be adjusted in three or more stages. It is possible. For example, mounting holes 42 as shown in FIG. 6B may be provided at a plurality of locations along the moving direction of the receiving portion 43. In this way, the opening amount of the opening C can be adjusted in a plurality of steps depending on which mounting hole 42 the regulation component 41 is mounted on.

Further, by replacing the regulation component 41, the opening amount of the opening C may be adjusted in a plurality of stages. Specifically, a plurality of regulation parts 41 such as a stepped pin having a thin end and a stepped pin having a thick end are provided, and the opening amount of the opening C is determined depending on which regulation part 41 is attached. It may be possible to adjust in multiple steps.

Further, the adjustment of the opening amount may be made steplessly adjustable. For example, a cam-shaped regulating portion (a shape eccentric to the axis of the regulating component 41) that engages with the receiving portion 43 is formed at the end of the rod-shaped regulating component 41, and the regulating member 41 is rotated around the axis. By doing so, the opening amount of the opening C can be adjusted steplessly.

As described above, according to the present embodiment, the restricting component 41 that can be attached to and detached from the gardening binding machine 10 is provided, and when the regulating component 41 is attached to the gardening binding machine 10, the regulating component 41 interferes. The opening amount of the opening C is regulated by. According to such a configuration, the opening amount can be adjusted only by attaching / detaching the regulating component 41, so that the opening amount can be adjusted easily and surely. In addition, since the opening amount does not change due to vibration during use, the adjusted opening amount can be kept constant.

Further, the regulation component 41 is a rod-shaped member that can be inserted and removed from the horticultural binding machine 10. According to such a configuration, the opening amount can be adjusted only by adding inexpensive parts without significantly changing the existing structure.

Further, if the regulated component 41 has a stepped shape having a different diameter, the opening amount can be adjusted according to the thickness of the diameter.

Further, a cover material 55 that can be attached to and detached from the handle is provided, and the regulation component 41 is attached to the horticultural binding machine 10 inside the cover material 55, and the cover material 55 restricts movement in the attachment / detachment direction.
