Rock drilling machinery and pneumatic tools

(While the Tentali Road Widening Paving Machine Publication, Yingyi Company has introduced two types of roads to widen the use of concrete for paving concrete for paving concrete.

During operation, one hopper of the fuselage discharges material to both sides.

The small diameter front wheel drives the steering wheel.

The larger diameter rear wheels are the rollers.

The engine is equipped with a relatively high-powered internal combustion engine and a hydraulic plate for compaction of the extruded material.

The width of the curved flat blade is also in addition to the width of the chain scraper conveyor and the propeller type vibrating roller.

The apparatus for extracting substances from a mixture is specialized, and a patented apparatus is used for extracting a viscous sample from a mixture, for example, from an asphalt material.

The device consists of a sieve member for screening the sample.

A solvent supply system and a discharge member for removing the analyzed material.

The structural features of the device ensure the minimum consumption of solvent.

The feed member is formed as a solvent feed sprayer having a rotary spray head or a fixed spray nozzle type.

Fig. Asphalt Pavement Adhesive Layer Reinforced with woven mesh. The German patented honeycomb woven mesh is mainly used for the reinforcement of asphalt road surface layer.

The net is formed by weaving the polymerized or heterocyclic compound fiber strands that can bear load in a crosswise and crosswise manner, and is glued or welded in sections and coated with attachments having a chemical bondability to the asphalt.

Woven nets have good adhesion properties and are a non-woven, thin material.

Fig. Asphalt Concrete Mixing Equipment, Russia One In the mixing equipment, the material is fed into the inclined drying cylinder by the conveyor, one end of the cylinder is equipped with a fire box with a nozzle, and there is a unloading device at the other end. Through them, it can be ensured that the materials are directly sent to the screening machine and sieved according to the granularity, and then the materials are successively fed into the stirring device to which the hot hopper weighing hopper and the asphalt meter are connected.

The hot gases and evaporation products generated during combustion are all introduced into the dust removal system and mixed with the asphalt concrete ingredients.

The process delivery of the ingredients into the mix must be carried out with a minimum of two conveyors arranged at an acute angle to the main plane of the vertical line in the conveying direction.

Compared with the standard drying drum, the cross-section of the fire box cross-section of the drying drum has a similar cross section of the fuel injection nozzle to reproduce the fast kinematics model of the fallen asphalt concrete particle material section.

The result of this process is a high productivity and high quality asphalt concrete mix formulation.

The discussion on the hydraulic system scheme of Chen Yuanji rock drilling machine and pneumatic tool guide rail hydraulic rock driller, Li Yijie, a knife mining machinery factory, described the problems exposed by the hydraulic system of the guide rail hydraulic rock drill in actual use, and expounded the rock drill and supply The combination of oil pumps, discussed the design of the hydraulic system of the aircraft, introduced the function of the hydraulic system, put forward the design of two hydraulic systems, simple and functional, compact structure and convenient maintenance, improve efficiency and reduce energy consumption.

Fig. Rock Drilling Rig Spiral Swivel Swivel Mechanism Design Publication, Zhongshi Yanping Mining Machinery describes the structural features of the screw-swept cylinder and its role in the drilling rig, and introduces the structure of the four large swing angle spiral oscillating cylinders, and The determination of the parameters and the method of calculation have explored several structural types of the back-converted-width mechanism, and pointed out that modern drilling rigs mostly use compound coordinate-type amplitude-varying mechanical images with both swing and rotation. Yang Duxi Hydraulic Drilling Machine Computer System In order to improve the operational economy of the hydraulic rock drill, the Nihon Watanabe Hideki Industrial Machinery Co., Ltd. has developed a computer system.

This kind of device, called a drilling and navigation system, can be used in tunnel drilling operations to relocate items that previously depended on the operator's visual sensation, such as the location of the hole to be drilled at the bottom of the corner hole.

It is displayed in a drilling pattern on a display mounted on a trolley.

This article introduces the general situation of the system (position detection sensor control system display device office computer device function (automatic search drilling device hole tail position, etc.) and characteristics.

Figure (Zheng Qiulin) Hydraulic Directional Lithotripes Journal, Riyoukou Fushou Oil Pressure Technology In the rock excavation of an urban underground tunnel project, the blasting operation will bring intense vibration and noise.

After the hydraulic directional crusher replaces the blasting operation, it will be an efficient and low-impact method.

The composition of this remote-controlled hydraulic pump reservoir in the booster is a high-quality orientation system developed in cooperation with Russia.

The oil pressure expands the high-pressure rubber tube inserted into the deep well, and acts on the wedge to cause the thrust element to act to break the rock surface.

The description of the types of specifications structure of the automatic detection of gravel automatically stop the supply of consumables applicable to the slope of the broken section after the rock and other issues.

A new type of pressure feedback hydraulic impactor was introduced at the Ginseng Seedling Plant, and Zhong Yang Kai Wall Machinery presented the structure and working principle of a new pressure feedback hydraulic impactor.

The so-called pressure feedback control is to achieve stepless adjustment of the impact energy of the impactor by continuously adjusting the pressure of the system. When the pressure is high, the impact energy is large, and when the pressure is low, the impact energy is small.

The impactor can adjust the system pressure for different working objects, thereby achieving the purpose of reducing the installed capacity of the host such as an excavator.

(Dental)'s Rock Drilling Journal, the British-Diamond Drilling Machine has a machine-heavy hole with no internal coupling to increase the piston diameter and achieve the shortest stroke impact at the same power to ensure that the bit is in closer contact with the rock.

Rock Drilling, Germany, a simplified rock drill structure in the patent.

It is controlled by a four-way three-position distributor.

The advantage is that the frequency is independent of the speed.
