Figure (Teng Dali Road Widening Paving Machine Journal, Yingyi Company launched two types of special equipment for road widening with drain concrete paving.
During the operation, the hopper of the fuselage discharges to both sides.
The small diameter front wheel drives the steering wheel.
The larger diameter rear wheel is the roller.
The machine is equipped with a high-power internal combustion engine and a hydraulic plate for compacting the material.
The width of the curved flat blade is furthermore, and the chain is provided with a chain scraper conveyor and a propelling vibrating roller.
The device for extracting substances from a mixture is specifically used for extracting a viscous sample from a mixture, for example, from a bituminous material.
The apparatus consists of a screen 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 minimum solvent consumption.
The feed member is formed as a solvent supply liquid discharge device having a rotary spray head or a fixed nozzle type.
Figure woven woven mesh for asphalt pavement bonding layer, Deyi patented honeycomb woven mesh is mainly used for the reinforcement of asphalt pavement.
The web is woven with a polymerized fiber or a heterocyclic fiber strand that can withstand the load, and is glued or welded in stages and coated with a chemically new adhesion to the asphalt.
The woven mesh has good adhesion properties and is a non-woven thin material.
Figure asphalt concrete mixing equipment, Russia 1 in the mixing equipment, the material is sent to the inclined drying cylinder by the conveyor, one end of the cylinder is equipped with a fire box with a nozzle, and at the other end is a discharge device, Through them, it can be ensured that the material is directly sent to the screening machine for screening according to the particle size, and then the materials are successively introduced into the stirring device of the hot hopper measuring bucket and the asphalt meter.
The hot gases and vaporized products generated during combustion enter the dedusting system and are mixed with the asphalt concrete ingredients.
The process of processing the ingredients into a mixture must be carried out with at least two conveyors arranged at an acute angle to the main plane of the vertical line in the conveying direction.
The fire box section of the drying cylinder has a similar cross section of the fuel injection nozzle compared with the standard drying cylinder surface to reproduce the fast kinematics model of the falling asphalt concrete particle section.
The result of this process results in a high productivity and high quality asphalt concrete mix.
Figure Chen Yuanji rock drilling machine and pneumatic tool rail type hydraulic rock drill hydraulic system program discussion, Zhong Li Huijie one knife mining machinery factory one describes the problem of the hydraulic system exposed by the rail type hydraulic rock drill in the actual use process, expounding the rock drill and the supply The combination of the oil pump discusses the design of the hydraulic system of the machine, introduces the function of the hydraulic system, and proposes the design scheme of the two hydraulic systems. It is simple and full-featured, compact in structure and convenient in maintenance, improving efficiency and reducing energy consumption.
The design of the spiral back-converting mechanism of the rock drilling rig, the Sinopec Yanping mining machinery describes the structural characteristics of the spiral oscillating cylinder and the role on the drilling rig. It introduces the structural forms of the four large swing angle spiral oscillating cylinders, as well as the main The parameters are determined and calculated, and several structural types of the back-transformation mechanism are discussed. It is pointed out that most modern rock drilling rigs use the computer system system of the composite coordinate-type variable-width mechanical drawing with both swinging and turning. In order to improve the operational economy of the hydraulic rock drill, the company has developed a computer system.
This type of device, called the drilling navigation system, can be used to drill a hole in the tunnel, such as a hole that is previously dependent on the operator's visual perception, such as the position at which the hole is drilled.
Displayed on the display mounted on the trolley in a drilling pattern.
This article describes the general situation of the system (position detection sensor control system display device office computer device function (automatic search for drilling device hole tail position, etc.) and features.
Figure (Zheng Qiulin) Hydraulic Directional Crushing Machine Journal, Rizhaokou Fushou Oil Air Compressor Technology In the urban rock tunnel excavation operation, the blasting operation will bring intense vibration and noise.
The hydraulic directional lithotripter will be a highly efficient and low-harm method after replacing the blasting operation.
This hydraulic pump remote control operation box is built in the power assist device and 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 the wedge element acts on the thrust element to break the rock face.
The description of the type and specification of the structure of the gravel automatic detection automatically stops the consumption of the trolley for the slope of the rock layer after the section is broken.
The new type of pressure feedback hydraulic impactor is published by the ginseng nursery, and the structure and working principle of a new type of pressure feedback hydraulic impactor are proposed.
The so-called pressure feedback control can achieve the purpose of stepless adjustment of the impact energy of the impactor through the stepless adjustment system pressure. 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.
Figure (Teng Dali) company's rock drilling machine magazine, Yingyi rock drill machine heavy aperture one machine without internal coupling, thereby increasing the piston diameter, the shortest stroke impact at the same power, to ensure that the drill bit and the rock closer contact.
Drilling machine special, Deyi simplified the structure of a patented rock drill.
Controlled by a four-way three-position distributor.
The advantage is that the frequency is independent of the speed.
