drill the weight of this kind of drill is relatively light, generally less than 25kg, when working with the hand to operate. Can be shot a variety of small diameter and shallow hole. Generally, only downward hole and close to the horizontal hole. Because it relies on manual operation, labor intensity, impact energy and torque smaller, drilling speed is slow, now underground mines rarely use it. Belong to this type of drill Y3, Y26 and other models.
(2) this kind of
drill is installed on the gas leg for operation, the gas leg can play a supporting and promoting role, which reduces the labor intensity of the operator, drilling efficiency is higher than the former, drilling depth of 2)5m, diameter 34)42mm horizontal or with a certain Angle of the gun hole, for the extensive use of mines. Such as YT23(7655), YT24, YT28, YTP26 and other models are such drill.
(3) telescopic upward type
