The QWY-30 portable drilling rig is a small portable drilling machine that is further optimized and improved on the basis of the WTY-30 drilling rig. It is suitable for drilling projects such as survey and exploration, geophysical exploration, road and construction exploration, and blasting holes. This drilling rig has the following features:

1. It adopts reasonable technical parameters and has a high degree of mechanization, which reduces labor intensity and improves work efficiency.

2. It adopts domestic advanced power and is light in weight. The gearbox is equipped with a transfer mechanism, which can achieve rapid hole sweeping. The clutch adopts an external dry clutch with a simple and compact structure, easy operation and maintenance. The speed shift handle is positioned by a sleeve spring, which is reliable and labor-saving to shift.

3. The turntable drive adopts a bottom-mounted spiral bevel gear pair, which is easy to adjust, smooth in movement, fully lubricated and has a long service life. The turntable can move away from the wellhead with the front frame, and the working position is spacious, which can be applied to various drilling methods.

4. The hydraulic feeding device is adopted, which is easy to operate and has high drilling efficiency. The high-pressure gear oil pump is selected, which is not easy to damage, increases the pulling capacity, and is conducive to handling accidents in the hole.

5. The drilling rig has a compact structure, small size, light weight, and the frame connection adopts a hinge form, which is highly detachable and easy to move, assemble and repair. When the entire drilling rig is moved, it is divided into five parts, and the weight of each part is less than 60Kg.

In short, in addition to retaining the main advantages of the WTY-30 drilling rig, this drilling rig is lighter in weight, more compact in structure, the weight of each part is more reasonable when relocating, and it is more easily dismantled and more convenient.
