Abstract
The utility model relates to a chain saw for a coal mining channeling machine. The chain saw comprises chain sheets, hinge pins for connecting the chain sheets, and a serrated knife. Two ends of the serrated knife are respectively provided with pin holes. The serrated knife is connected and combined with the chain sheets by the hinge pins and the pin holes to form a chain-shaped body. The chain saw is a device used together with the coal mining channeling machine. When the chain saw is used, the chain-shaped body which is formed by connecting and combining the serrated knife with the chain sheets by the hinge pins and the pin holes is driven by the coal mining channeling machine to directly act on a coal bed, and the serrated knife saws a horizontal or a vertical cut channel in the coal bed so as to prepare for the pretreatment of an improved mining method. A knife head adopting the serrated knife for multi-point work is used for dealing with the coal bed, thus not only realizing fast coal bed sawing, but also greatly reducing drilling resistance and further improving the work efficiency of the coal mining channeling machine. The chain saw has simple structure, small volume and low cost and is an ideal coal bed exploration facility used together with the coal mining channeling machine.
Description
Technical field
The utility model relates to coal-cutting machinery, is specifically related to a kind of coal mining slotting machine chain saw.
Background technology
At present, the exploitation of coal mainly contains dual mode, and the one, the mining type of digger is mainly used in the exploitation in large-scale colliery.The 2nd, medium and small colliery mainly is to adopt the blasting excavation mode, promptly inserts explosive in the boring on the coal seam and carries out blasting excavation, though this mode is exploited rapidly, the efficient height is used widely in actual production.But this kind coal mining pattern does not only satisfy the demand of socio-economic development to growing coal, does not guarantee that more explosive runs off and the illegal security of the lives and property of bringing of using.This kind method very easily causes the generation of personal injury and large-scale accident of mine disaster simultaneously, becomes the major safety risks of coal mining enterprise's sustainable development.The coefficient of mining of this kind method only has 40% in addition, has not only caused the serious waste of coal resources, and because the huge shaking force of explosive blasting operation, it is low that the coal of its extraction goes out the piece rate.Thereby improve the recovery method that falls behind, and develop novel winning apparatus, be the task of top priority of coal mining industry.
Summary of the invention
The purpose of this utility model provide that a kind of novel recovery method uses with the matching used chain saw of coal mining slotting machine.
The utility model purpose realizes in the following manner, this coal mining slotting machine comprises the chain sheet with chain saw and is used for the bearing pin of connection chain sheet, it also comprises serrated knife, and the serrated knife two ends is respectively equipped with pin-and-hole, and serrated knife is connected with the chain sheet through bearing pin, pin-and-hole and constitutes catemer.
Described serrated knife is made up of the blade on connecting base and being connected base, and the two ends that connect base are respectively equipped with pin-and-hole, and blade is provided with cutter head.This blade also can be designed to the aliform structure, and the angle between two aliform blades is 0～50 degree.
The technological progress that the utility model is obtained: this chain saw is and the matching used device of coal mining slotting machine.Be connected the catemer chain saw under the driving of coal mining slotting machine that constitutes by serrated knife with the chain sheet through bearing pin, pin-and-hole during use and directly act on the coal seam, by serrated knife the coal seam sawing is gone out a horizontal or vertical grooving, for improved recovery method is carried out pretreated preparation.Employing is carried out operation by the cutter head of serrated knife multiple spot operation to the coal seam, and not only sawing coal seam speed is fast, creeps into resistance but also greatly reduce, thereby has further improved the operation effect of whole coal mining slotting machine.This chain saw overall structure is simple, and volume is little, and cost is low, is a kind of and the matching used desirable seam mining facility of coal mining slotting machine.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.As shown in Figure 1, the coal mining slotting machine that the utility model relates to comprises chain sheet 1 with chain saw and is used for the bearing pin 2 of connection chain sheet 1, and it also comprises serrated knife, and the serrated knife two ends is respectively equipped with pin-and-hole, and serrated knife is connected with chain sheet 1 through bearing pin, pin-and-hole and constitutes catemer.Described serrated knife is made up of the blade 4 on connecting base 3 and being connected base 3, and the both ends that connect base 3 are provided with pin-and-hole respectively, and the top of blade 4 is welded with the cutter head 5 that alloy or diamond or other high hardness material are made.Can weld monomer blade 4 on the connection base 3 of serrated knife, the angle α that also can weld 4 of two aliform blades, 4, two aliform blades is 0～50 degree.
This chain saw is connected with chain sheet 1 through bearing pin, pin-and-hole by serrated knife and constitutes, its connected mode as shown in Figure 1, the serrated knife of hilted broadsword head and double-pole head is connected order with other ordering of also can adopting of chain sheet 1, be connected at interval successively with double-pole body serrated knife with chain sheet 1 as hilted broadsword body serrated knife, also can adopt hilted broadsword body serrated knife and many groups spaced in flakes 1 with being connected of double-pole body serrated knife, also can adopt other order that is connected.
