The working principle of the detachable screen structure repeatedly used for the swing screen to generate vertical vibration in the embodiment is as follows: the large-scale swing screen assembly can become certain angle installation with the horizontal plane, and when the swing screen was circular motion, knocked both sides elastic ball 32 in the branch system 3 and because the unbalanced movable hinge structure who makes two elastic balls 32 of connection produced the reciprocal swing in the vertical plane in the focus position, and screen cloth body 4 is knocked in the reciprocal of elastic ball 32, triggers screen cloth body 4 and produces longitudinal acceleration. The springs 24 in the C-shaped frame 22 generate reciprocating vibration under the excitation of the back-and-forth vibration of the screen body 4, so that the reciprocating motion of the screen in the vertical direction is further increased, a vertical acceleration is provided for the screen body 4, the screening efficiency is improved, and the screen is prevented from blocking holes; a plurality of detachable screen systems are arranged on the supporting rack 11 through bolts 5, and a single screen (namely the screen body 4) is more convenient and faster to replace. The elastic balls 32 on two sides of the connecting rod 33 collide with the screen body 4 to obtain larger vibration force locally, so that material clamping stagnation is reduced, and the screening effect is further improved.
The screen body 4 is arranged on the supporting plate 21 through the bolt 5, and when the screen body 4 is damaged in the screening process, the damaged screen body 4 is selected for replacement, so that the screen is convenient and efficient and the replacement cost is low; knocking the strut system 3 is also connected to the C-shaped frame 22 through bolts 5, if damage is found, the damaged part of the structure can be replaced, and the device is convenient, efficient and low in replacement cost. The C-shaped frame 22 is fixedly connected to the support frame 11 through the pressing plate 12 by the bolts 5, and when the C-shaped frame 22, the springs 24 and the upper and lower rubber sealing strips (i.e., the upper sealing strip 25 and the lower sealing strip 23) are damaged, the C-shaped frame can be detached for replacement or repair.
The upper and lower rubber sealing strips are arranged outside the C-shaped frame 22 and on the supporting plate 21 through vulcanization treatment, so that materials are prevented from entering the C-shaped frame 22 and blocking the C-shaped frame 22, and the displacement of the spring 24 is limited. The high-flexibility rubber is adopted as a sealing strip material, so that the vertical movement of the screen can be influenced very little on the premise of playing a sealing role. The C-shaped frame 22 and the support plate 21 are installed in a matched mode through the limiting shaft 26 and the linear bearing 27, and therefore the whole support plate 21 and the screen body 4 can only do vertical jumping in the vertical plane relative to the C-shaped frame 22.
The structural rigidity of the cross support in the knocking support rod system 3 is larger than that of the screen body 4, and the position of the knocking subsystem arranged on the cross support can be adjusted according to the size of the specific screen body 4 so as to generate better impact action. In the vibration process, the screen body 4 collides with the knocking support rod system 3 to impact, so that the screen body 4 is prevented from blocking holes.
The vertical sieve disclosed by the invention has the advantages of simple structure, scientific and reasonable design and convenience in use, and the sieve can generate vertical motion in the sieving process to provide longitudinal acceleration for materials, so that the phenomenon of hole blockage of the sieve is effectively solved, and the sieving effect is improved. The detachable structure of the screen enables the screen to be conveniently and quickly replaced when the screen is locally damaged. Compared with an elastic ball type swinging screen structure, the structure reduces the elastic balls and the elastic ball frame for bearing the elastic balls, greatly reduces the overall quality and the manufacturing cost of equipment, and realizes the lightweight design of the vibrating screen.
The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention, but all the insubstantial modifications or changes made within the spirit and scope of the main design of the present invention, which still conform to the technical problems of the present invention, should be included in the scope of the present invention.
