PD-Y28 Pneumatic Drilling Attachment with 360 degree swing drive for Mini 4 tons Excavator

PD-Y28 Excavator Attached Pneumatic Rock Drill changes the tradition of manual hand-held pneumatic rock drills.Y28 is installed on a rail that can swing and move up and down, and then the rail is installed on the excavator with a quick-change connector.

PD-Y28 drilling operation still uses air compressor to drive Y28 for drilling, but the drilling angle and the movement of the rock drill are derived from the hydraulic power of the excavator, which is controlled by the imported electromagnetic control valve sets.

The operator uses electric control box knob controls the drilling operation in the cab, which is convenient, fast, safe and efficient. PD-Y28 improves the working environment, work efficiency and reduces labor intensity.

Application field: It is widely used in marble quarrying, tunnel boring, stonework, mining and various rock drilling operations. It is an indispensable operating tool in railway, highway, metallurgy, coal, water conservancy and hydropower construction and national defense stonework.

Product advantages Features:

1. 1.There is no need to purchase rock drilling rigs separately, which greatly saves costs.

1. 2.Utilizing the crawling and rotating advantages of the excavator, it can work in severe working conditions with a wide operating range.

1. 3.Unique oil circuit valve design, adjustable oil circuit distribution according to different working conditions to achieve the best rock drilling effect. The valve and electromagnetic reversing valve are all imported parts, which are precise, sturdy and durable.

1. 4.The function of the excavator can be restored when not in use, and the existing resources can be fully utilized.

1. 5.Low noise, low vibration, energy saving and high efficiency, low failure rate and high reliability;

1. 6.Centralized operating mechanism, flexible start-up, convenient use and maintenance.

Installation instructions and pressure commissioning

1. A1 / B1 controls the forward / backward of pneumatic rock drill

A2 / B2 circuit controls the ± 180 ° rotation of the drilling rig

2.Connection with excavator

T port is connected with the oil return port of the excavator

The P port is connected with the oil outlet of the crushing hammer

The oil drain port is directly connected to the hydraulic oil tank of the excavator

3.Pressure regulation

Adjust the main pressure (≤ 10MPa). Clockwise is to increase the pressure and counterclockwise is to reduce the pressure

Propulsion pressure reducing valve: control the forward pressure of pneumatic rock drill (generally 3-6mpa, adjusted according to rock working conditions)

The four oil ports are throttle valves to adjust the flow speed everywhere

Installation of electrical parts

Electric control box: switch, push and rotate

Connect excavator battery DC24V

The plug is linked with the plug on the valve block
