The selection of down-the-hole drilling rigs mainly considers several factors, such as the diameter, depth, direction, angle and drilling accuracy of engineering blast holes, rock conditions, construction site conditions and construction period. Then select the appropriate rig according to these requirements, and match the corresponding air compressor. At present, large, medium and small are widely used in the domestic market. High, medium and low wind pressure, track tread and rubber tread methods; driving forces include diesel engines, electric motors, wind motors and other models. At present, the  hydraulic dth drilling rig  for small and medium crawler walking is analyzed as follows. Power type of drilling rig. There are three basic types of power for domestic small and medium-sized crawler self-propelled DTH rigs. The rig is driven by a diesel engine to drive a group of hydraulic oil pumps, and the output hydraulic oil is separately supplied. 1. Walking hydraulic motor 2. Rotat

Hydraulic dth drilling rig supplier   share with you: The rock drilling machine is driven by a petrol engine. The impact piston of the impact drill rod uses the rotation of the ratchet to rotate the drill rod on the rock to impact the rock. The piston moves up and down. The powder of the rock blows out of the hole. A cemented carbide drill head with a diameter of 28-40 mm is installed under the drill rod according to the different hardness of the rock. According to the required hole size, the alloy bit with different sizes is replaced, which is suitable for drilling and blasting in various mines. Internal combustion gasoline rock drilling machine is also called internal combustion rock drill. Because its petrol engine is small in size and easy to carry, the overall drilling machine weighs only more than 20 kilograms, and does not need to be equipped with any auxiliary equipment. It only needs to be installed with a drill rod, and the drill head can work. Therefore, it is suitable

During the selection of  water well drill rig  equipment, it is necessary to pay attention to a series of issues to ensure that the selection of the water well rig is correct, so that the Water Well Rig can better meet its production needs. When selecting a well drilling rig, the purpose of purchasing a well drilling rig needs to be clarified, and what kind of well drilling equipment is needed. Water well drilling rigs supplier  to share with you: The purpose of water well drilling rig selection is generally divided into 3 types: update, development, and expansion. The purpose of the updated model is mainly to care about new water well drilling rigs with high efficiency, high precision and high performance to replace the backward water well drilling rigs. When selecting a model, it is more important to focus on the technical performance of the water well rig. By purchasing a new type of water well rig, the efficiency of I application can be improved, and production costs and consump

Crawler mounted hydraulic dth drilling rig  refers to a fully hydraulic rock drilling and drilling machine with a crawler traveling mechanism. The crawler hydraulic drilling rig is composed of a power unit and a hydraulic system, a crawler traveling mechanism, a drill frame equipped with a hydraulic rock drill and a propeller, a support arm, and a drill rod unloading device. 1 Introduction: The crawler hydraulic drilling rig refers to a full hydraulic rock drilling and drilling machine with a crawler traveling mechanism. 2 structure: The crawler hydraulic drilling rig is composed of a power unit and a hydraulic system, a crawler traveling mechanism, a drill frame equipped with a hydraulic rock drill and a propeller, a support arm, and a drill rod unloading device. The drilling hole diameter is 35 ~ 125mm, and the drilling depth can reach 30m, which is suitable for large-scale stone excavation and drilling operations. Except for high-pressure air or water used for drilling and dr

Development: The domestic  DTH drill rig  was first produced in the Xuanhua area of Hebei in the 1950s. Through the continuous investment of the country and its own development, the performance and technical content of the rig have been greatly improved. Later the world's top 500 companies in the United States, Sweden, and other countries came to Xuanhua to invest in building factories or joint ventures. Its products and production technologies are used as scientific textbooks for scientific research and teaching. Therefore, the synonym for down-the-hole drilling rigs in China is also called "Xuanhua drilling rigs." Since the 1990s, Hebei Xuanhua has formed an equipment production base. Some enterprises focus on the development and production of the latest type of high-performance, low-consumption, open-air various types of drilling machines, and at the same time, they can be used as accessories. The product is widely used in large, medium and small mines, hydropower

Our company independently developed an  advanced crawler mounted dth drilling rig  that is safe, environmentally friendly, and efficient. This machine can be widely used in various open-pit mines, quarries, construction sites, and other occasions. The essence of DTH rock drilling is to make the impactor dive into the hole during rock drilling to reduce the energy loss caused by the impact energy transmitted by the drill rod, thereby reducing the effect of hole depth on rock drilling efficiency. Down-the-hole rock drilling equipment is a down-the-hole drilling rig. YQ-80, YQ-100, and QZ-165 are commonly used in China's underground mines. I. Overview The  all in one dth automatic drill rig  consists of a slewing mechanism, a lifting mechanism, a pushing mechanism, a support mechanism, and an impact mechanism. Second, the lane column type An  automatic crawler mounted dth drill rig  is an impact rotary drilling rig. Its internal structure is different from that of ordinary ro
