The down-the-hole hammer is the basic equipment required for drilling projects. The down-the-hole hammer is an integral part of the down-the-hole drilling rig and the working device of the down-the-hole drilling rig. Widely used in mining, coal, water conservancy, highways, railways, construction and other engineering operations.
Its working principle is: the compressed air enters the DTH hammer through the drill pipe, and then is discharged from the drill bit. The exhaust gas is used for slag removal. The rotational motion of the breaker is provided by the rotating head, and the shaft thrust is provided by the propeller and transmitted to the breaker through the drill pipe. The adapter is mainly used to transmit propulsion and rotational motion to the drill bit. The snap ring controls the axial movement of the drill bit, and the check valve is used to prevent rock slag and other debris from entering the hammer when the supply of compressed air is stopped. During the drilling process, the drill bit is pushed into the hammer and pressed against the adapter. At this time, the piston directly impacts the drill bit to drill the rock. As the drill bit lifts off the bottom of the hole, it begins to blow violently. This allows materials to be collected centrally.
Generally speaking, hammer models are mainly classified according to its weight, drilling depth, drill bit diameter, drilling rig processing capacity, drilling rig power, etc. The weight of a large down-the-hole drill hammer will be relatively heavy, and the drilling depth and diameter will be relatively large.
There are many factors to consider when choosing a drill rig. You cannot choose this type of drilling rig just because of its large processing capacity. Choosing a suitable drilling rig needs to be based on the materials to be broken, the processing capacity during work, and the power of the drilling rig.
Different models of drilling rigs will have different prices. It involves factors such as the different materials used in the drilling rig, the technological content of the drilling rig, the processing capabilities of the drilling rig, etc., which affect the price of the drilling rig. When purchasing a drill rig, you should consider whether the model matches the drill rig you need. Think carefully and try to choose a reliable manufacturer with high product quality.
