Embodiment Construction

[0039] 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.

[0040] 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

[0041] Below in conjunction with accompanying drawing, each preferred embodiment of the present invention is described further:

[0042] refer to figure 1 with 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.

[0043] In this embodiment, one end of the plow conveying part 36 is provided with a head drive device 1...

Abstract

The invention discloses a coal plough. The coal plough comprises a conveying portion of the coal plough, a plough head, a sliding frame which is matched with the plough head and double endless chains, wherein a head drive device which is used for driving the plough head is arranged at one end of the conveying portion of the coal plough, a tail drive device which is used for driving the plough head is arranged at the other end of the conveying portion of the coal plough, the plough head is arranged on the sliding frame, the head drive device and the tail drive device are wound round double endless chains, and the plough head is driven to do reciprocating movement along the sliding frame by double endless chains. Therefore, the coal plough is hauled by two chains and head end drive and tail end drive are used, so that the technical problem that requirements on the height of an operation platform are increased due to the fact that the diameter of a single chain is increased and the height of the whole coal plough is increased is solved.

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...
