Abstract
The utility model discloses a freezing coal machine sampler, and comprises a character, a middle screw shovel (1) and a central axis (9). The utility model is characterized in that the bottom of the character is provided with an annular milling shearing disc (4) fixed with the central axis (9), the bottom of the annular milling shearing disc (4) is provided with a horniness milling incisor (5), the centre of the annular milling shearing disc (4) is provided with a horniness aiguille (6), a bevel blade (8) is arranged in the connective suit(10) of the annular milling shearing disc (4) and the central axis (9), a horniness crushing head(7) is arranged in the circumference of the connective suit (10) of the annular milling shearing disc (4) and the central axis (9). The utility model is a freezing coal machine sampler which can sample the coal with freezing coal and a plurality of blocks and has simply structure and expediently operation.
Description
Technical field
The utility model relates to a kind of coal freezing machinery sampling thief.
Background technology
The Coal Mechanical sampling apparatus begins to be widely used and to play a significant role in enterprises such as fuel-burning power plant, steel plant, mainly is that mechanical sampling can satisfy modern enterprise sampling request quickly and accurately.But in northern China cold season, coal is freezed by severe cold, and general sampling head can't cut the hard coal that freezes, and contains the more coal of stone for some, has been sampled into a great problem.
The utility model content
Technical problem to be solved in the utility model provide a kind of can be to freezing coal and containing the coal freezing machinery sampling thief that the more coal of stone is sampled.
In order to solve the problems of the technologies described above, the utility model adopts technical scheme to be: the bottom at the cylinder sample holder of sampling thief is provided with the annular milling dish that installs with central shaft, described annular milling dish bottom is provided with hard milling tooth, the center is provided with the hard drill bit, on the adapter sleeve of annular milling dish and central shaft, be provided with bevel blade, on the circumference of the adapter sleeve of annular milling dish and central shaft, be provided with the broken piece of hard.
As a kind of improvement of the present utility model, be provided with wear-resisting steel bushing in cylinder sample holder bottom,
Adopt the mechanical sampling device of technique scheme, during sampling, sampling thief integral body is done descending motion under the driving of jacking gear, this moment, sampling thief central spiral shovel and lower annular milling dish were made high speed rotating, send into the cylinder sample holder after will freezing cutting and crushings such as lump coal or stone, realized sampling, so, the utility model be a kind of can be to freezing coal and containing that the more coal of stone is sampled and simple in structure, easy to operate coal freezing machinery sampling thief.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is an annular milling dish front view of the present utility model;
Fig. 3 is an annular milling dish vertical view of the present utility model.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, bottom at the cylinder sample holder 2 of sampling thief is provided with the annular milling dish 4 that is connected by axle sleeve 11 with central shaft 9, described annular milling dish 4 bottoms are provided with hard milling tooth 5, the center is provided with hard drill bit 6, be provided with bevel blade 8 on the adapter sleeve 10 of annular milling dish 4 and central shaft 9, third-class distributing equally is furnished with the broken piece 7 of hard on the circumference of annular milling dish 4 and the adapter sleeve 10 of central shaft 9.
As a kind of improvement of the present utility model, be provided with wear-resisting steel bushing 3 in cylinder sample holder 2 bottoms, and described wear-resisting steel bushing 3 and cylinder sample holder 2 are convenient to change the serviceable life of having improved sampling thief by being threaded.
Adopt the mechanical sampling device of technique scheme, during sampling, sampling thief integral body is done descending motion under the driving of jacking gear, this moment, sampling thief central spiral shovel 1 and lower annular milling dish 4 were made high speed rotating, hard milling tooth 5 on the annular milling dish 4, the hard drill bit 6 at center will be sent into cylinder sample holder 2 after bevel blade 8 on the adapter sleeve 10 and the third-class broken piece 7 of hard that distributes equally cloth will freeze cutting and crushings such as lump coal or stone, realize sampling.
