Embodiment Construction

[0017] Such as figure 1 As shown, a brick-making raw material screening device includes a screen frame 10 supporting a screen 11, two juxtaposed slideways 9 extending in the left and right directions and a connecting rod 4, and the two slideways are respectively used to slide and support the screen frame The front and rear sides (8 and 6), one end of the connecting rod is hinged with the left side 5 or the right side 7 of the screen frame, and the other end is hinged with the crank (the crank is specifically driven by the eccentric wheel 3, which is driven by the motor 1 and the belt 2). The rod, the screen frame and the slideway jointly constitute a crank slider mechanism to make the screen reciprocate, and the height of the screen gradually increases or decreases in the left and right directions.

[0018] There are two ways to realize the gradual increase or decrease of the height of the screen:

[0019] The first way: the front and rear sides of the frame are parallel to ...

Abstract

The invention provides a screening device for brickmaking raw materials, which comprises a screen frame for supporting a screen mesh, two parallel slideways extending leftwards and rightwards and a connection rod, the two slideways are respectively used for supporting a front edge and a rear edge of the screen frame in a sliding way, one end of the connection rod is hinged with a left edge or a right edge of the screen frame, the other end of the connection rod is hinged with a crank, the crank, the connection rod, the screen frame and the slideways together form a crank slider mechanism so as to enable the screen mesh to do a reciprocating motion, and the height of the screen mesh is increased or lowered gradually in left and a right directions. Brickmaking raw materials to be screened are conveyed onto the screen mesh, the screen mesh is driven by the crank to do the reciprocating motion in the left and the right directions, the brickmaking materials are screened, a part of qualified raw materials fall down, and the other part of raw materials slide down accompany with an inclination of the screen mesh at the height. The particles of brickmaking raw materials are uniform by screening, so that a normal operation of brickmaking equipment is guaranteed, and working efficiency and product quality are increased.

Description

technical field [0001] The invention relates to a screening device for solid matter, in particular to a screening device for brick-making raw materials. Background technique [0002] Because the brick making machine uses slag, construction waste, etc. as raw materials, the particle size of these raw materials is extremely uneven. Most existing brick making machines are not equipped with raw material filtering devices, resulting in easy damage to brick making equipment and molds, and product quality cannot be guaranteed. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a brick-making raw material screening device. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: [0005] A screening device for brick-making raw materials, including a screen frame supporting the screen, two juxtaposed slideways extending in the left and right dire...
