The price of excavation machinery is generally ranging between 2 million yuan and 8 million yuan, which is special and higher.Working method: It is mainly composed of walking institutions, work agencies, shipping agencies and reprinting agencies.As the walking agency advances, the cut heads in the work institutions are constantly crushing rocks and transporting crushed rocks.It has the advantages of safety, efficiency, and quality of Chengxiang, but the cost is large, the structure is complicated, and the loss is large.
The research level of excavation machinery
In recent years, with the rapid development of my countrys coal industry, the coal machine industry, which is dependent on lip and teeth, has also received increasing attention.In the "Several Opinions on Promoting the Healthy Development of the Coal Industry" in the coal industry program, in the National Coal Industry Science and Technology Conference and the structural adjustment policy of the coal industry issued by the National Development and Reform Commission, they all involve the development of large -scale coal wells comprehensive coal mining equipmentWait.Tiger and recovery are important production links in coal mines.
The rapid excavation of coal mine lanes is a key technical measure for coal mines to ensure high -yield and stable yield.The mining technology and its equipment level directly excavate the ability and safety of coal mines.High -efficiency mechanization excavation and support technology are the necessary conditions for ensuring that the mining is high -yield and efficient, and it is also the development direction of lane -away excavation technology.
With the development of comprehensive mining technology, the annual output of millions of tons or even 10 million tons of super working surface has appeared in China, which has increased the number of lanes consumption in the annual consumption, which has made the digging into the coal mine into efficient intensive production production.Common and key technologies.The most important way in my countrys coal lane efficient excavation method is the supporting line of cantilever excavators and single anchor rod drilling machine, also known as the comprehensive mechanization of coal lanes. Formulating excavator.
The cantilever excavator is a combination of cutting, transporting, walking, operation and other functions. It is mainly used to cut off the underground rocks, coal or semi -coal rock lanes with an arbitrary section.Although the design of domestic excavations is now said to have a distance from international advanced technology, domestic technical levels can basically meet domestic needs.Large and medium -sized excavations are constantly innovating.
What are the use of the use of digging machinery
(1) After the operation is stopped according to the prescribed operation order, the excavation shot should be returned to the safe location and placed the shovel on the bottom.Cut the head and shrink back, cut the arm on the bottom plate, close the water door, and hang the cable and water pipe.
(2) In the large working surface of the water, the electrical equipment such as motor, control boxes, and operation boxes should be covered.
What is the starting machine program?
(1) Pull out the emergency stop button on the operation box and pull to the normal position.
(2) Use a special tool to switch the power switch of the operation box to the "pass" position.
(3) Put the fault detection switch in the electrical box to the "normal" position.
(4) Ringling warning, start the oil pump motor, and then start the cutting motor (only when the support switch on the operation box is turned to the "run" position, the cutting motor can be started), and the boot process is completed.
(5) Operate the corresponding operating handle to achieve working procedures.
(6) After the working program is completed, you can rotate the corresponding motor operation switch to the stop position by turning the corresponding motor operation switch.When you need an emergency shutdown, you can implement it by pressing the emergency stop button on the operating box, or pressing the emergency stop button on the electrical box or pressing the non -drivers side -stop button of the excavator.
(7) When the driver leaves the drivers seat, he must push the "emergency stop" button on the operation box and use a special tool to hit the power switch to the "break" position.
