EARTH-REMOVING DEVICE FOR CONSTRUCTION MACHINERY

PROBLEM TO BE SOLVED: To provide an earth-removing device for construction machinery, in which positions of left and right pin holes provided in a bracket welded and fixed to an earth-removing blade do not shift from each other, thereby attachment to a vehicle body becomes easy.SOLUTION: An earth-removing device provided on at least one of front and rear of an undercarriage of construction machinery includes: an earth-removing blade 9 extending in the width direction of the undercarriage; a lifting unit fixed to the undercarriage and interposed between the earth-removing blade 9 and the undercarriage, for lifting the earth-removing blade 9 up and down with respect to the undercarriage; and a bracket 24 fixed to the earth-removing blade 9 and to which the lifting unit is attached. The bracket 24 includes a pair of right attachment part 27 and left attachment part 28 to which the lifting unit is to be attached, which are formed integrally by being joined to a joint part 30. 【課題】排土板に溶接固定したブラケットに設けられた左右のピン孔の位置が互いにずれることなく、したがって車体への取り付け作業が容易となる建設機械の排土装置を提供する。【解決手段】建設機械の下部走行体の前部及び後部の少なくとも一方に設けられた排土装置であって、前記下部走行体の幅方向に延びる排土板９と、前記下部走行体に固定されて前記排土板９と前記下部走行体との間に介装され、前記排土板９を前記下部走行体に対して昇降させる昇降ユニットと、前記排土板９に固定され、前記昇降ユニットが取り付けられるブラケット２４とを備え、前記ブラケット２４は、前記昇降ユニットを取り付けるべき一対の右取付部２７及び左取付部２８を有し、前記右取付部２７及び左取付部２８は、連結部３０にて連結されて互いに一体となっている。【選択図】図２
