Problems solved by technology

[0002] At present, the classification of large-grained materials in coal mines mostly adopts circular vibrating screens and bar screen frames. The overall height of the screens is large, there are many pipe beams, the structure is relatively cumbersome, the vibration mass is large, and the energy consumption is also high.
At the same time, it cannot solve the problem that large flakes enter the screen and cause damage to lower-level equipment

Embodiment Construction

[0012] Such as figure 1 , figure 2 As shown, the screen is mainly composed of a screen frame 1, a trapezoidal screen frame 9, an excitation beam 3, an exciter 4, a double output shaft motor 6, a flexible coupling 5, a base 8 and a holding reduction device. The screen frame 1 is composed of a surrounding plate and a support, and the screen frame 1 is fixed on a base 8 through a screen frame support 7 . The trapezoidal screen frame 9 is fixed on the base 8 by the spring 2, and the trapezoidal screen frame 9 is made up of round steel and supporting steel plates. The trapezoidal screen frame 9 is provided with double exciting beams 3, and the two ends of the exciting beams 3 are equipped with exciters 4, and the exciters 4 are connected with double output shaft motors 6 through flexible couplings 5. The motor 6 is fixed on the base 8 through supports.

Abstract

The invention discloses a big granularity vibrating lip screen, which belongs to a classification device of the coal preparation plant, the invention is mainly used for classification of gross coal, and is also used for classification of other big block materials; the screen surface adopts the ladder shape space grid structure for solving the problem occurred when the big block slice stone entersthe lower part of the screen: a lateral plate of the screen frame is propped on a base, and is totally out of the joining vibration; an excitation beam is arranged under the ladder shape screen mesh frame, vibration generators are arranged on the two ends of the excitation beam, a double-output shaft electromotor drives the vibration generators by a shaft coupling, then the exciting force is transferred to the ladder shape screen mesh frame. Therefore, the invention has low overall height, small driving power, simple structure and reliable running.

Description

technical field [0001] The invention relates to a vibrating grading screen with large particle size, which is mainly used for grading raw coal in coal mines, and can also be used for grading various bulk materials, belonging to coal preparation equipment. Background technique [0002] At present, the classification of large-grained materials in coal mines mostly adopts circular vibrating screens and bar screen frames. The overall height of the screens is large, there are many pipe beams, the structure is relatively cumbersome, the vibration mass is large, and the energy consumption is also high. At the same time, it cannot solve the problem that large flakes enter under the screen and cause damage to lower-level equipment. Contents of the invention [0003] Aiming at the above problems, the present invention proposes a vibrating grading sieve with large particle size, which has the characteristics of small overall height, simple structure, small vibration mass and low ener...
