Detailed Description

The present application is described in further detail below with reference to figures 1-6.

The embodiment of the application discloses a washing vibrating screen. Referring to fig. 1 and 2, the ore washing vibrating screen comprises a base 100, a screen surface 300 and a vibrating motor 200, wherein the screen surface 300 comprises a first screen surface 310 with larger screen holes and a second screen surface 320 with smaller screen holes, the first screen surface 310 and the second screen surface are obliquely arranged above the base 100, and the end higher than the ground is a feeding end. The first screen surface 310 is installed at the uppermost portion of the base 100 and is formed by splicing a plurality of screen plates 311. The second screening surface 320 is mounted below the first screening surface 310 and is capable of further screening ore passing through the openings in the first screening surface 310. A guide rail 600 is arranged at the feeding end of the first screening surface 310, the direction of the guide rail 600 is the same as the feeding direction of the ore, and the ore falls onto the guide rail 600 and slides onto the first screening surface 310. The supporting frame 900 is arranged between the first screening surface 310 and the second screening surface 320, and the supporting frame 900 is fixedly connected with the base 100, so that the phenomenon that the first screening surface 310 is sunken towards the position close to the second screening surface 320 can be reduced.

Referring to fig. 3 and 4, the first screening surface 310 is formed by connecting a plurality of screening plates 311 through a detachable assembly 400, the detachable assembly 400 includes a connecting member 410 and a fixing member 420, the connecting member 410 is a U-shaped frame, the U-shaped frame has two straight bars parallel to each other, the straight bars are in threaded connection with the fixing member 420, and the fixing member 420 is disposed on one side of the screening plate 311 away from the second screening surface 320, so that a worker can fix the detachable assembly 400 conveniently.

Referring to fig. 5, two through holes 421 are formed in the fixing member 420, and a distance between the through holes 421 is the same as a distance between the straight bars of the U-shaped frame. Both ends of the connecting member 410 are provided with threads, and the connecting member is fixed by nuts 500 after passing through the sieve holes of two adjacent sieve plates 311 and the through holes 421 on the fixing member 420, and the nuts 500 are in threaded connection with both ends of the U-shaped frame and abut against the fixing member 420. And a locking device 700 is arranged between the nut 500 and the fixing member 420, so that the phenomenon of looseness generated when the nut 500 is vibrated can be reduced. Fixing piece 420 top still is provided with sleeve 800, and the joint hole 810 on the sleeve 800 can with nut 500 joint, to the space packing between two nuts 500, can reduce the phenomenon of ore card between two nuts 500.

Referring to fig. 6, the anti-loosening device 700 includes two identical annular shims 710, the annular shims 710 being divided into a large serrated surface 711 and a small serrated surface 712. When the nut 500 is installed with the end of the connecting member 410 passing through the center of the annular washers 710, the large serrated surfaces 711 of the two annular washers 710 are brought close to each other and the serrations mesh with each other. The dip angle of the large sawtooth surface 711 of the annular gasket 710 is larger than that of the fixture between two adjacent threads on the connecting piece 410, so that the lifting distance between the annular gaskets 710 is larger than that of the nut 500, and the anti-loosening function is realized.

The implementation principle of the ore washing vibrating screen in the embodiment of the application is as follows: a plurality of sieve plates 311 are connected together to form first screening surface 310 by detachable assembly 400, ore falls onto guide rail 600 when conveying to shale shaker department, and the preliminary screening through guide rail 600 department slides onto first screening surface 310, and the ore that the granule is less than first screening surface 310 sieve mesh passes the sieve mesh and falls on second screening surface 320 and carries out further screening under the effect of vibrating motor 200. The first screening surfaces 310 are connected by a detachable assembly 400, the detachable assembly 400 comprises a connecting piece 410 and a fixed piece 420, the connecting piece 410 is fixed on the fixed piece 420 through a nut 500, and a locking device 700 between the nut 500 and the fixed piece 420 can reduce the phenomenon that the nut 500 is loosened. When a portion of the first screening surface 310 is deformed or damaged by the impact of ore, the worker only needs to remove the damaged screening deck 311 and replace it. Because the securing member 420 of the removable assembly 400 is positioned above the first screening surface 310, a worker may perform an operation on the first screening surface 310 by removing the sleeve 800 and then unscrewing the nut 500, thereby separating the connecting member 410 from the securing member 420 and removing the damaged screen panel 311 for replacement. Because the support frame 900 is further arranged below the first screen surface 310, the operation of replacing the screen plate 311 by a worker standing on the first screen surface 310 is facilitated, and the phenomenon that the first screen surface 310 collapses when the screen plate 311 is replaced is reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
