摘要： PURPOSE: A charging unit for blasting and a blasting method using the same are provided to reduce noise and vibration due to blasting and reduce the scattering of rock since blasting energy is transmitted to the inner surface of a charging hole. CONSTITUTION: A charging unit for blasting comprises a tube(11), a metal shell(16), and a buffer solution(17). The tube is inserted into a charging hole with explosive. The tube is divided into a relatively small metal receiving portion(13) on one side thereof and a relatively large liquid receiving portion(14) on the other side. The metal shell is accepted to a metal space of the tube. A liquid space is filled with the buffer solution.

摘要： PURPOSE: A snow removal device for a tractor is provided to improve snow-removing work efficiency by reducing frictional resistance with ground and to remove snow regardless of road condition by mounting the snow removal device on the rear side of the tractor. CONSTITUTION: A snow removal device for a tractor comprises a T-shaped hollow support(4), a snow removing frame(6), left and right working cylinders(18), and a rotary plate(8). The T-shaped hollow support is coupled with a left connection bar(14) and front and rear connection bars and is connected to a connection bar(12) through a connection piece(16) of a front head. The snow removing frame is formed on the front and rear connection bars and comprises an upper plate(22). The left and right working cylinders are formed on the left and right connection bars of the T-shaped hollow support. The rotary plate is hinge-connected to the rear side of the rear side of the snow removing frame by an elastic rod.
摘要翻译：目的：提供一种用于拖拉机的除雪装置，通过减少与地面的摩擦阻力来改善除雪工作效率，并通过将除雪装置安装在拖拉机的后侧，而不考虑道路状况来除雪。构成：用于拖拉机的除雪装置包括T形中空支撑件（4），除雪框架（6），左右工作缸（18）和旋转板（8）。 T形中空支撑件与左连接杆（14）和前后连接杆联接，并通过前头的连接件（16）连接到连接杆（12）。除雪框架形成在前连接杆和后连接杆上，并包括上板（22）。左右工作缸形成在T形中空支撑件的左右连接杆上。旋转板通过弹性杆铰接连接到除雪框架后侧的后侧。
