Abstract
The invention discloses a coal washing screening device comprising a screen body and a driving device connected with the screen body. Two sides of the screen body extend outwards to form guide rails, fixing supports are mounted on two sides of the bottom middle of the screen body in a mirror image manner, a transmission shaft is connected between the fixing supports and is in running fit with a transmission bar through a movable connection device, the other end of the transmission bar is fixedly connected with a limit guide bar, the driving device comprises a shell, a gear sleeve is arranged in the shell and integrally of a hollow kidney-shaped structure, the limit guide bars matched with the shell in a drawing manner are fixed on two sides of the gear sleeve, tooth spaces are formed on the upper and lower side of the middle inside the gear sleeve in a mirror image manner, and an intermittent gear meshed with the tooth spaces is arranged in the gear sleeve. The coal washing screening device is simple in structure, stable and reliable in transmission, large in reciprocating stroke and satisfactory in scattering and screening effect, coal briquettes can be effectively screened even if being inputted once by a large quantity, and overall recovery rate can reach above 98%.
Description
Technical field
The present invention relates to coal mine equipment processing and manufacturing field, be specifically related to a kind of coal washing screening plant.
Background technology
What in common coal washer, mostly install in the market is reciprocating sieve, although this reciprocating sieve can meet general screening coal and the needs of coal separation in certain degree, but in actual use procedure, because coal cinder is along with the vibrations of reciprocating sieve are less, cause the amplitude of coal cinder motion also accordingly less, especially after once dropping into a large amount of coal cinders, this phenomenon is just more obvious, directly causes its in use lower phenomenon of the coal cinder rate of recovery.
Summary of the invention
The object of the invention is to provide a kind of coal washing screening plant, and it can solve existing problem in background technology effectively.
In order to solve existing problem in background technology, the drive unit that it comprises sieve body 1 and is attached thereto, the both sides of described sieve body 1 extend outward respectively guide rail 2, both sides, middle part, the bottom surface mirror image of described sieve body 1 is provided with hold-down support 3, between this hold-down support 3, be connected with power transmission shaft, described power transmission shaft is rotatably assorted by articulating device and drive link 4, the other end of described drive link 4 is fixedly connected with spacing guide rod 5, described drive unit comprises shell 6, in this shell 6, be provided with tooth cover 7, described tooth cover 7 integral body are the long waist shaped structure of hollow, its both sides are fixed with the spacing guide rod 5 coordinating with shell 6 pulls, upper and lower both sides, middle part mirror image in described tooth cover 7 offers teeth groove 8, in described tooth cover 7, be provided with the partial gear 9 being meshed with teeth groove 8, this partial gear 9 is connected with drive motors 10, described drive motors 10 is arranged in shell 6.
Described shell 6 comprises upper shell 61 and lower house 62, between described upper shell 61 and lower house 62, by bolt, is spun and is fixed into one, and the junction between described upper shell 61 and lower house 62 offers the guide groove coordinating with guide rod 5 pulls.
Owing to having adopted above technical scheme, the present invention has following beneficial effect: simple in structure, transmission is reliable and stable, reciprocating stroke is larger, the loose effect of bucket and screening effect are comparatively desirable, even if once drop into a large amount of coal cinders, also can effectively sieve, and recycled in its entirety rate can reach more than 98%.
Accompanying drawing explanation
In order to be illustrated more clearly in the present invention, below in conjunction with accompanying drawing, embodiment is briefly described.
Fig. 1 is structural representation of the present invention;
Wherein:
1. sieve body; 2. guide rail; 3. hold-down support; 4. drive link; 5. spacing guide rod; 7. tooth cover; 8. teeth groove; 9. partial gear; 10. drive motors;
6. shell; 61. upper shells; 62. lower houses.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Referring to Fig. 1, this specific embodiment is to be achieved by the following technical solutions, the drive unit that it comprises sieve body 1 and is attached thereto, the both sides of described sieve body 1 extend outward respectively guide rail 2, both sides, middle part, the bottom surface mirror image of described sieve body 1 is provided with hold-down support 3, between this hold-down support 3, be connected with power transmission shaft, described power transmission shaft is rotatably assorted by articulating device and drive link 4, the other end of described drive link 4 is fixedly connected with spacing guide rod 5, described drive unit comprises shell 6, in this shell 6, be provided with tooth cover 7, described tooth cover 7 integral body are the long waist shaped structure of hollow, its both sides are fixed with the spacing guide rod 5 coordinating with shell 6 pulls, upper and lower both sides, middle part mirror image in described tooth cover 7 offers teeth groove 8, in described tooth cover 7, be provided with the partial gear 9 being meshed with teeth groove 8, this partial gear 9 is connected with drive motors 10, described drive motors 10 is arranged in shell 6.
Described shell 6 comprises upper shell 61 and lower house 62, between described upper shell 61 and lower house 62, by bolt, is spun and is fixed into one, and the junction between described upper shell 61 and lower house 62 offers the guide groove coordinating with guide rod 5 pulls.
Owing to having adopted above technical scheme, this specific embodiment has following beneficial effect: simple in structure, transmission is reliable and stable, reciprocating stroke is larger, the loose effect of bucket and screening effect are comparatively desirable, even if once drop into a large amount of coal cinders, also can effectively sieve, and recycled in its entirety rate can reach more than 98%.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art should be appreciated that its technical scheme that still can record aforementioned each embodiment modifies, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
