Embodiment Construction

[0038] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The technical solution of the present invention will be described below with reference to the accompanying drawings and in combination with embodiments.

[0039] The basic idea of ​​the present invention is to design a coal plow, which adopts double-chain traction, and the two ends of the machine head and machine tail are driven

[0040] Below in conjunction with accompanying drawing, each preferred embodiment of the present invention is described further:

[0041] refer to figure 1 and figure 2 , shows the structure of the coal plow proposed in this embodiment, and the coal plow includes: a coal plow conveying part 36, a plow head 4, a sliding frame 3 matched therewith, and a double infinite chain 7.

[0042] In this embodiment, one end of the plow conveying part 36 is provided with a head drive device 1 ...

Abstract

A coal planer comprises a coal planer conveying unit (36), a head (4), a sliding frame (3) matched with the head and a double non-polar chain (7). The head (4) is set on the sliding frame (3) and the double non-polar chain (7) is provided around the two ends of the coal planer conveying unit (36). The coal planer conveying unit (36) comprises a driver (1,6) for driving the head (4). The driver (1,6) and the double non-polar chain (7) together drive the head (4) along the sliding frame (3) to move back and forth. Since the double stranded coal planer is provided with chain wound around head and tail drive units, the need to increase the diameter of single-chain and height of the coal planer and the work face can be avoided.

Description

technical field [0001] The invention relates to the field of coal mining machinery, in particular to a coal plow. Background technique [0002] With the strengthening of the country's management of resources and the substantial increase in resource costs, the coal industry has entered a period of rapid development. However, due to the lack of effective mining methods, most of the thin coal seams, which account for 20% of the total coal resources, have not been mined. At the same time, the resources of thick coal seams are gradually being exhausted. Thin coal seam mining is inevitable. [0003] At present, in the main coal production bases in China, a small number of thin coal seams have been mined, using thin coal seam shearers or blast mining methods, which have low efficiency, high failure rate and potential safety hazards. Existing coal plows are longwall mining and transportation equipment mainly used in coal mines with thin coal seams of 1.0 to 2.0 meters. Its technolo...
