【考案の詳細な説明】
本考案は油圧ショベル等で使用するパケットの改良に関
する。[Detailed Description of the Invention] The present invention relates to an improvement of a packet used in a hydraulic excavator or the like.
従来の油圧ショベルの側板、背板からなるパケットは１
枚による構造であり、パケット、アームおよびブームの
動作時、停止時の衝撃により、バケツ１〜の側板および
背板部分が共振し、騒音発生源となっている。A conventional hydraulic excavator has one packet consisting of side plates and back plates.
When the bucket, arm, and boom operate and stop, the side and back plates of the bucket 1 resonate and become a source of noise.
また現在、油圧ショベルは低騒音型の機種が開発され、
エンジン、油圧系統の低騒音化が実施されている。In addition, low-noise models of hydraulic excavators are currently being developed.
Engine and hydraulic system noise reduction has been implemented.
しかし、パケット部については、低騒音化が全く着手さ
れておらず、ユーザー側からの要求からも、せ゛ひとも
パケット部についても低騒音化への改良が必要となった
。However, no efforts have been made to reduce the noise of the packet section, and in response to requests from users, it has become necessary to improve both the device and the packet section to reduce noise.
そこで本考案は上記の点を鑑み、低騒音化を計ったパケ
ットを提供することを目的としたものであり、側板およ
び背板の全部あるいは一部を２枚板構造としたことを特
徴とするものである。Therefore, in view of the above points, the present invention aims to provide a packet designed to reduce noise, and is characterized by having a two-plate structure for all or part of the side plates and back plate. It is something.
本考案の実施例を以下図面に従って詳細に説明する。Embodiments of the present invention will be described in detail below with reference to the drawings.
第１図において、一般のパケットは左、右側板１ａ、１
ｂ、背板２よりなり、背板２の先端に複数個のティース
３が固着されている。In Fig. 1, the general packets are left and right plates 1a, 1
b. It consists of a back plate 2, and a plurality of teeth 3 are fixed to the tips of the back plate 2.
この左右側板１ａ、ｌｂ、背板２の全部あるいは一部を
２枚板Ａ、Ｂの構造にし、その要部断面は第２図の通り
である。All or part of the left and right side plates 1a, 1b and the back plate 2 are structured as two plates A and B, and a cross section of the main part thereof is shown in FIG.
２枚の板Ａ、Ｈの間隙に砂Ｃを封入し、板Ａ、Ｂの外周
部から砂がこぼれないようにする。Sand C is sealed in the gap between two plates A and H to prevent sand from spilling out from the outer periphery of plates A and B.
尚２枚の板Ａ、Ｂの板厚は変えて同相振動の防止を計る
。The thickness of the two plates A and B is changed to prevent in-phase vibration.
このような２枚板構造によりパケット、ブーム、アーム
操作時、停止時にパケットが振動した場合、パケットの
振動は板Ａと板Ｂからその間に封入した砂Ｃに伝達され
る。With such a two-plate structure, when the packet vibrates when the packet, boom, or arm is operated or stopped, the vibration of the packet is transmitted from the plates A and B to the sand C sealed between them.
砂Ｃの各粒子は互いに独立しているため各粒子の挙動は
異なる。Since each particle of sand C is independent from each other, each particle behaves differently.
従って、はさみ込まれた砂Ｃの各粒子間に摩擦が生じ、
この摩擦による減衰により、共振による騒音発生をおさ
えられる。Therefore, friction occurs between each particle of sandwiched sand C,
This damping due to friction suppresses noise generation due to resonance.
このように本考案によれば、パケットを構成する側板、
背板の全部あるいは一部を間隙を設けた２枚構造とし、
該間隙に砂を封入したことにより、パケット振動時２枚
の板の間に封入された砂で摩擦現象が生し、この摩擦に
よる減衰により板の振動が急激に減衰し、共振による騒
音発生をおさえ、パケットの低騒音化が計られ、産業上
有益なものである。As described above, according to the present invention, the side plates constituting the packet,
All or part of the backboard has a two-panel structure with a gap,
By filling the gap with sand, when the packet vibrates, the sand sealed between the two plates causes a friction phenomenon, and due to the damping caused by this friction, the vibration of the plates is rapidly attenuated, suppressing noise generation due to resonance, The packet noise is reduced and is industrially useful.
