Pin shaft installation structure, scarifier and bulldozer
The invention relates to the field of engineering machinery, and discloses a pin shaft installation structure, a scarifier and a bulldozer. The pin shaft installation structure comprises a pin shaft (10) and a first part and a second part which are used for being connected through the pin shaft, wherein the first part and the second part are provided with a first installation hole (31) and a second installation hole (41) which correspond to each other separately; and the hole wall of the first installation hole is provided with a first conical surface portion which is gradually expanded in a direction away from the second installation hole. The pin shaft installation structure further comprises a conical sleeve (20) which is assembled between the pin shaft and the first conical surface portion, wherein the conical sleeve is provided with a second conical surface portion (21) with an outer surface capable of being matched with the first conical surface portion. The hole diameter of the tail end of the first installation hole is enlarged through the first conical surface portion, the first installation hole and the second installation hole can be conveniently aligned and located, the pin shaft can be smoothly inserted, and the pin shaft, the first installation hole and the second installation hole can be accurately adjusted to an axial centering position by arranging the conical sleeve.
本发明涉及工程机械领域，公开了一种销轴安装结构、松土器和推土机，销轴安装结构包括销轴(10)以及用于通过销轴连接的第一部件和第二部件，第一部件和第二部件上分别设置有彼此对应的第一安装孔(31)和第二安装孔(41)，第一安装孔的孔壁具有沿远离第二安装孔的方向渐扩的第一锥面部，销轴安装结构还包括装配在销轴和第一锥面部之间的锥套(20)，锥套具有外表面能够与第一锥面部配合的第二锥面部(21)。第一安装孔通过第一锥面部扩大了末端的孔径，便于与第二安装孔对准定位，销轴能够顺利插入，通过设置锥套，可以将销轴、第一安装孔和第二安装孔准确地调整到轴向对中的位置。
