本発明は製砂機のハンマーの改良に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to an improvement in a hammer for a sand machine.
従来の技術
この種製砂機のハンマーとして本出願人は既に
実公昭53−7238号公報および実公昭53−17017号
公報に記載の考案を提供している。Prior Art As a hammer for this type of sand machine, the present applicant has already provided a device described in Japanese Utility Model Publication No. 7238/1983 and Japanese Utility Model Publication No. 17017/1983.
上記のハンマーは、それ以前のハンマーが、頭
部の消耗により大形の脚板及び保護板をも一緒に
交換しており、非常に無駄が多かつた点を改良す
るため、アームに取付体を介してハンマーを装着
し、ハンマーを消耗の都度アームから段階的に突
出させ得るようになすと共に、ハンマーのみ交換
可能としたものである。 The above-mentioned hammer has a mounting body on the arm in order to improve the fact that the previous hammer had to replace the large leg plate and protective plate together due to wear and tear on the head, which was very wasteful. The hammer is attached through the arm so that the hammer can be protruded step by step from the arm each time it wears out, and only the hammer can be replaced.
発明が解決しようとする問題点
上記公知のハンマーは、アームに取付体を介し
て取付ける構造であるため、アーム及び取付体の
構造が複雑化するのみならず、大形化し、破砕室
内への取付個数を増加させることができなかつ
た。Problems to be Solved by the Invention The above-mentioned known hammers have a structure in which they are attached to the arm via a mounting body, which not only complicates the structure of the arm and the mounting body, but also increases their size, making it difficult to install them inside the crushing chamber. It was not possible to increase the number of pieces.
一般に、破砕室内での製砂作業は、ハンマーの
取付個数を増加させる程、良好となる傾向にあ
る。 Generally, the sand making work in the crushing chamber tends to improve as the number of attached hammers increases.
また、従来、砕石場で発生する粒径2.5〜５

製砂するには、ハンマーの数量を増加させる必要
がある。 In addition, conventionally, particle sizes of 2.5 to 5
Pebbles with a diameter of approximately 1/2 m/m were used for asphalt pavement, but recently, asphalt pavement construction methods have changed and they are no longer used, and a large amount of pebbles is left over. In order to make sand, it is necessary to increase the number of hammers.

優れているものである。Effects of the Invention According to the present invention, not only can the mounting body be omitted, but also there is no need to provide a guide groove for positioning and fixing the mounting body in stages, so the shape of the arm can be made smaller and simpler. This makes it possible to downsize the entire device and increase the number of attached hammers. Furthermore, the hammer can be turned upside down and fixed to the hammer mounting board at the tip of the arm with bolts, allowing effective use of the hammer. Further, since the positioning engagement portion and the mounting bolt hole of the hammer mounting board are formed to be biased toward the tip side, the effective usage amount of the hammer can be increased. Of course, as the hammer wears out, the mounting device can be changed in the radial direction, and since the main part of the hammer is made of a wear-resistant material such as ceramic, it has high hardness and wear resistance. It is also excellent.
