Abstract

The utility model relates to the technical field of detectors, in particular to a coal sampling device, which comprises a driving motor and a rotating shaft, wherein the rotating shaft is connected with the output end of the driving motor, the other end of the rotating shaft is connected with a connecting rod, a sleeve barrel is sheathed on the outer periphery of the connecting rod, the inner wall of the upper part of the sleeve barrel is glidingly connected with the outer wall of the lower part of the rotating shaft, the end part of the connecting rod is connected with a drill bit, the drill bit comprises a shaft rod, the other end part of the shaft rod is fixed with at least one spiral blade, and a hard cutter blade is embedded on the cutting edge of the spiral blade. The coal sampling device has the advantages that in the design, the structure is reasonable, the operation is easy, the use is convenient, in addition, double spiral blades are adopted, and a frozen coal layer can be more conveniently drilled for carrying out coal sampling.

Description

The ature of coal sampling apparatus

Technical field

The utility model relates to a kind of technical field of pick-up unit, especially a kind of ature of coal sampling apparatus.

Background technology

At present, coal mining enterprise adopts artificial sample mostly in the Coal Quality testing process, promptly by the sample collector with spade Direct Sampling on coal yard dump or the coal car, with specialized equipment the quality index of coal is analyzed then, Cai Yang method is manually to dig 20cm on the top layer, compartment of coal car to take a sample deeply more like this, because for those northern area weather in winter, coal surface has freezing, sampling depth is hindered, and not only hand labor intensity is big, wastes time and energy again; Some businessman adulterates in addition, adulteration mixes colm in the fat coal, and gangue or stone are mixed in the coal, and these colms, gangue or stone are embedded in the depths, compartment, be difficult for being found, wait the coal in the compartment to be transported between crushing vehicle, clay into power, after inserting burner hearth, can find that just the coal of sampling is inconsistent with the actual coal that uses, be caused enormous economic loss, also not satisfy actual demand simultaneously with coal unit with coal unit.

The utility model content

The technical problems to be solved in the utility model is: in order to overcome the above-mentioned middle problem that exists, provide a kind of and conveniently drill through, reduce labour intensity, the time saving and energy saving and ature of coal sampling apparatus accurately of sampling.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of ature of coal sampling apparatus, comprise drive motor and the rotating shaft that is connected with the drive motor output terminal, the described rotating shaft other end links to each other and is connected to connecting rod, the periphery of described connecting rod is with sleeve, between the outer wall of the inwall of upper cartridge and rotating shaft bottom for being slidingly connected, described interlinking lever end is connected with drill bit, described drill bit comprises axostylus axostyle, the fixing a slice screw blade at least of axle end is inlaid with hard blade on the cutting edge of described screw blade.

In order to make its boring dynamics stronger, described screw blade is two, and the drill edge angle of two screw blade compositions is 110 °～120 °.

The beneficial effects of the utility model are, ature of coal sampling apparatus of the present utility model, and this project organization is reasonable, processing ease, the convenient use can accurately be aimed at and be sampled, in addition, adopt the double helix blade, can conveniently drill and freeze the coal seam and carry out ature of coal is sampled.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an A place structure for amplifying synoptic diagram among Fig. 1.

1. drive motor among the figure, 2. rotating shaft, 3. connecting rod, 4. sleeve, 5. drill bit, 51. axostylus axostyles, 52. helical blades, 53. hard blades.

Embodiment

In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

Ature of coal sampling apparatus as shown in Figure 1, comprise drive motor 1, drive motor 1 output terminal is connected with rotating shaft 2 one ends, rotating shaft 2 other ends are connected with connecting rod 3 one ends, the periphery of connecting rod 3 is with sleeve 4, and for being slidingly connected, the inwall on sleeve 4 tops is fluted between the outer wall of the inwall on sleeve 4 tops and rotating shaft 2 bottoms, on the outer wall of rotating shaft 2 bottoms the projection that matches with groove is arranged, connecting rod 3 other ends are connected with drill bit 5.

Ature of coal sampling apparatus as shown in Figure 2, comprise drill bit, drill bit 5 comprises axostylus axostyle 51, and two screw blades 52 are fixed in axostylus axostyle 51 the other end, the drill edge angle that is inlaid with 53, two screw blades of hard blade, 52 compositions on the cutting edge of screw blade 52 is 115 °.

Principle of work of the present utility model: rotating shaft 2 upper ends are connected by the output terminal of leading screw with drive motor 1, when carrying out coal sampled, rotating shaft 2 is rotated under the driving of drive motor 1, drivening rod 3 and drill bit 5 rotate together and insert in the dump, when the double-screw type blade 52 on the drill bit 5 rotates to the dump designated depth, rotating shaft 2, connecting rod 3 and drill bit 5 stop action, sleeve 4 is up drawn, because the blade on the drill bit 5 shape in the shape of a spiral distributes, blade has constant slope, just can easily gather a certain amount of sample coal on the double-screw type blade 52 like this, thereby the sample coal carried out a series of detection convenient.

With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
