Abstract
The invention relates to a full hydraulic multi-blade-saw lump coal mining machine comprising large blade-saws, large blade-saw supports, large blade-saw slide rails, small blade-saws, cutting cylinders, a hydraulic pump, and a mining power device. The mining power device is a main structure mainly used for providing power for the forwarding of the mining machine and the operations of the large blade-saws and the small blade-saws. The hydraulic pump is respectively connected with the large blade-saws, the small blade-saws, the cutting cylinders, and the large blade-saw supports. With the hydraulic pump, the large blade-saws move back and forth, the small blade-saws move up and down, the cutting cylinders move horizontally, and the heights of the large blade-saw supports can be adjusted. There are four small blade-saws which move up and down on a coal wall through the hydraulic pump. The cutting cylinders are arranged on the highest end of the mining machine, and are used for cutting the upper end of coal. Under the effects of the large blade-saw supports and the hydraulic pump, the large blade-saws draw the cut and molded coal out.
Description
Technical field
The invention belongs to mining equipment, particularly a kind of all-hydraulic multiple blade saw lump coal coal-winning machine.
Background technology
The coal that traditional coal-winning machine is adopted all is broken, and quality is bad, and operating efficiency is low in addition, can only unidirectionally tunnel, and influences job schedule.
Summary of the invention
To the objective of the invention is in order overcoming the above problems, a kind of all-hydraulic multiple blade saw lump coal coal-winning machine to be provided, can dig out into the coal of piece, and be all hydraulic, flexibility ratio is very big during work, increases work efficiency greatly.
The present invention is achieved in that
A kind of all-hydraulic multiple blade saw lump coal coal-winning machine, it comprises big blade saw, large stretch of saw rest, big blade saw slideway, little blade saw, cutting-cylinder, hydraulic pump and coal-winning machine power set, wherein the coal-winning machine power set are agent structures; Mainly provide power, to the work of the advancing of coal-winning machine, big blade saw and little blade saw power is provided, hydraulic pump links to each other with big blade saw, little blade saw, cutting-cylinder, large stretch of saw rest respectively; Its effect is to let big blade saw do move back and forth, and lets little blade saw move up and down, and lets cutting-cylinder do horizontal movement; Let large stretch of saw rest adjustment highly, little blade saw is four altogether, moves up and down on the coal wall through hydraulic pump simultaneously; Cutting-cylinder is in the top of coal-winning machine; Its effect is that the upper end of coal is cut open, and big blade saw is pulled out the coal that cuts moulding under the effect of large stretch of saw rest and hydraulic pump.
Described a kind of all-hydraulic multiple blade saw lump coal coal-winning machine, two by name of its cutting-cylinder, big blade saw, large stretch of saw rest, big blade saw slideway, and the two ends that respectively are distributed in coal-winning machine are symmetrical structure.
Advantage of the present invention is:
Automaticity is high, and unearthed coal becomes piece property strong, high efficiency, and digging is convenient back and forth.
Description of drawings
Fig. 1 is a floor map of the present invention.
The specific embodiment
According to shown in Figure 1
A kind of all-hydraulic multiple blade saw lump coal coal-winning machine; It comprises big blade saw 1, large stretch of saw rest 2, big blade saw slideway 3, small pieces saw 4, cutting-cylinder 5, hydraulic pump 6 and coal-winning machine power set 7; Wherein coal-winning machine power set 7 are agent structures, and hydraulic pump 6 links to each other with big blade saw 1, small pieces saw 4, cutting-cylinder 5, large stretch of saw rest 2 respectively, and small pieces are sawed 4 and are four altogether; Link to each other with hydraulic pump 6 simultaneously; Cutting-cylinder 5 is in the top of coal-winning machine, and big blade saw 1 links to each other with hydraulic pump 6, and big blade saw slideway 3 links to each other with large stretch of saw rest 2.
Coal-winning machine power set 7 at the uniform velocity advance, and big blade saw slideway 3 is that speed change is advanced, but the two is remaining the relative motion distance.
Described a kind of all-hydraulic multiple blade saw lump coal coal-winning machine, its cutting-cylinder 5, big blade saw 1, large stretch of saw rest 2, big blade saw slideway 3 respectively are two, and the two ends that respectively are distributed in coal-winning machine are symmetrical structure.
Described a kind of all-hydraulic multiple blade saw lump coal coal-winning machine, when mining when from left to right going, employing be that the cutting-cylinder 5 in left side, big blade saw 1 and four small pieces saws 4 on right side carry out digging.
