Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip receiver of a reaper for temporarily collecting cut branches and leaves.

[0002]

2. Description of the Related Art Conventionally, a fixed blade having a plurality of blades provided on a side at predetermined intervals in a longitudinal direction and a movable blade having a plurality of blades provided on a side at predetermined intervals in a longitudinal direction are provided. The mowing machine, in which the movable blade reciprocates in the longitudinal direction with respect to the fixed blade and cuts the branches and leaves, temporarily collects the cut branches and leaves to prevent the branches and leaves from scattering around. Chip receivers are used. This chip receiver was attached to the blade part of the reaper by screwing.

Further, in order to protect the blade portion when not in use, a blade cover for covering the blade portion is put on. When placing the blade cover, the tip receiver used at the time of using the reaper is removed and the blade cover is placed. When using the reaper, the blade cover is no longer needed and is removed.

[0004]

However, when the chip receiver is attached and detached, the above-described structure in which the chip receiver is locked with screws requires a separate tool, and even if a knob nut is used. It is necessary to attach and remove the knob nut, which causes trouble for the operator.

On the other hand, if a blade cover is separately provided to protect the blade portion, it is difficult to manage the chip receiver and the blade cover, and the chip receiver and the blade cover may be lost.

Accordingly, the present invention provides a tip receiver that facilitates attachment and detachment of a reaper to and from a blade portion.
Provided is a chip receiver having a function of a blade cover.

[0007]

According to the first aspect of the present invention, there is provided an elongated blade (21, 22) having a plurality of blade tips projecting laterally in the longitudinal direction, and the blade (21, 22) being superposed on the blade (21, 22). Blade holder (23, 2) for holding the blade (21, 22)
4) A tip receiver (11) of a reaper attached to a reaper (D) having a blade part (2) having a reaper (2) having a cutting part (2). Attachment portions (132, 142) for locking to the blade holders (23, 24) during use, and the attachment portions (1).
32, 142), and a collecting portion for collecting the cut leaves and leaves. The collecting portion is formed so as to cover the cutting edge of the cutting blade when the reaper is not used. It is formed as a cover part (131, 141) to be stored, and the cover part (131, 141) is slid in the longitudinal direction of the blade part (2) to be detachably locked to the blade holder (23, 24). I did it.

According to a second aspect of the present invention, in the tip receiver of the reaper according to the first aspect, the blade holder (23, 2
4), a locking portion (231, 241) formed along the longitudinal direction of the blade portion is formed, and the mounting portion (14) is formed.
2) The blade portion (2) slides in the longitudinal direction of the blade portion (2) to engage with the locking portions (231, 241).
It is characterized by being removable.

It is composed of The chip receiver 12 is also formed of an elastic material such as a resin material or a thin iron plate. The mounting portion 122 is folded up on the side edge on the side opposite to the collecting portion 121 so that the end portion faces the collecting portion 121, and the cross-sectional shape in the direction orthogonal to the longitudinal direction is the tip of the arrow. 123 formed as described above
Is provided. And, in this folded portion 123,
Engaging portion 12 cut out from side end surface toward collection portion 121
4, 124 are provided in two places. This engagement portion 12
4 and 124 are provided at the same intervals as the locking portions 231 and 231 protruding from the upper surface of the blade portion 2 described above.

In order to attach the chip receiver 12 to the blade 2, the locking portions 231, 231 may be mounted on the side of the blade 2.
The tip receiver 12 is slid along the upper surface of the blade portion 2 so that the engagement portions 124 and 124 are aligned with the position of the blade portion 2. Since the tip receiver 12 is formed of a material which is elastically deformed, when the tallest portion of the folded portion 123 passes through the heads of the locking portions 231 and 231, the folded portion 123 is elastically deformed. And the blade part 2
Can pass between the upper end surface of the head and the heads of the engagement bodies 231 and 231. After being attached, this portion serves as a stopper.

The locking portions 231 and 231 are not limited to those provided with screws, but may be provided integrally with the blade portion 2, for example.

The mounting portion 132 has three semicircular engagement portions 135 to 135 along the longitudinal direction on the side edge opposite to the side edge on which the cover portion 131 is formed. .

On the other hand, the blade portion 2 of the reaper has an upper blade 21 and a lower blade 22 provided so as to overlap the upper blade 21. These are pressed down from above and below by flat blade holders 23 and 24. The blade holders 23 and 24 are attached to the blade portion 2 by screws 25. The upper blade holder 23 is provided with locking portions 231 and 231 that have both side edges protruding upward in FIG. 6 and extend along the longitudinal direction of the blade portion 2.

When the cutter 2 is stored in the cover 131 of the tip receiver 13 when the reaper is not used, the engaging members 134 and 13 of the cover 131 are inserted from the tip end of the cutter 2.
4 is aligned with the inner surfaces of the locking portions 231 and 231 of the blade holder 23, and the tip receiver 13 is moved to the blade portion 2.
The blade part 2 is attached by sliding along the longitudinal direction of. In addition, the interval between the outer surfaces of the engagement members 134 and 134 of the cover 131 is formed to be slightly larger than the interval between the inner surfaces of the locking portions 231 and 231 of the blade holder 23, or the width of both is made substantially the same. If the engaging bodies 134 are slightly expanded outwardly, the tip receiver 13 does not fall off the blade 2 even when the tip of the reaper faces downward.

On the other hand, when the reaper is in use, the cover 131 as a collecting portion is extended to the side of the blade portion 2 and the tip receiver is attached to the blade portion 2 so that the cover 131 faces upward. Thirteen attachment parts 132 are attached and used as a chip receiver. In this case, the screw 25 of the blade part 2 is loosened, the mounting part 132 is applied to the lower side of the blade holder 24, and the engaging part 1 formed on the side edge of the mounting part 132 is formed.
Align the 35 ‥ 135 with the screw 25 ‥ 25 and engage the screw 25 す る 25 by tightening the screw 25 ‥ 25 again.

Next, a fifth embodiment of the present invention will be described with reference to FIGS.

The chip receiver 14 is made of an extruded resin material or an elastic material such as a thin iron plate, and serves as a collecting portion when the reaper is used as a chip receiver. When not in use, the blade part 2
The cover part 141 for storing the inside of the cutter and the mounting part 142 to be attached to the blade part 2 when used as a chip receiver when the reaper is used are integrally formed so as to form a dogleg ( (See FIG. 9).

The cover part 141 has a shape like a sheath of a sword having a cavity formed therein similarly to the cover part of the fourth embodiment (see FIGS. 6 to 8). Inside, a storage portion 143 for storing the blade portion 2 is formed. In addition, a slit is provided on one side surface of the cover portion 141 in the center along the longitudinal direction. At both ends of the slit, engaging bodies 144 and 144 formed by being bent toward the inside of the cover 141 (the lower side in FIG. 10) are provided over the entire area in the longitudinal direction.

On the other hand, the mounting portion 142 is formed in substantially the same manner as the mounting portion (see FIGS. 1 and 2) of the chip receiver according to the first embodiment.
