DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] Referring to Figure 1 as shown, the present utility model provides a technical solution: a vibrating screen for a building materials mine, including a general support 1, a support frame 2 is installed inside the general support 1, a sieve frame 3 is fixedly installed inside the support frame 2, an anti-jamming structure 4 is provided inside the sieve frame 3, and a support structure 5 is provided on the surface of the sieve frame 3.
[0030] The specific settings and functions of its anti-jamming structure 4 and support structure 5 will be specifically described below.
[0031] Referring to Figures 1-5As shown, in this embodiment: The anti-jamming structure 4 includes a plurality of horizontal bars 41 fixedly connected to the inner side of the sieve frame 3, and a plurality of vertical bars 42 are slidably connected to the side walls of the sieve frame 3 and the plurality of horizontal bars 41. By sliding the sieve frame 3 and the vertical bars 42 on the horizontal bars 41, when a certain gap is pulled out between the two vertical bars 42, the work of easily removing the stuck stones can be achieved.
[0032] A bolt 43 is slidably connected inside the vertical bar 42, and a plurality of jack holes 48 are evenly formed on the surface of the sieve frame 3. The size of the jack holes 48 is adapted to the size of the bolt 43. The bolt 43 is inserted into the inner side of the corresponding jack hole 48 on the sieve frame 3, so as to achieve the locking and fixing work of the vertical bar 42 after movement. One end of the bolt 43 is fixedly connected with a pull block 47, and the other end of the bolt 43 is fixedly connected with an auxiliary head 46 in a frustum shape. By providing the auxiliary head 46 in a frustum shape, the efficiency of inserting the bolt 43 into the inner side of the jack hole 48 is improved. A stop block 45 is fixedly connected to the side wall of the bolt 43, and a spring 44 is sleeved on the surface of the bolt 43. The two ends of the spring 44 are fixedly connected between the inner side of the vertical bar 42 and the stop block 45 respectively. The bolt 43 is inserted into the inner side of the corresponding jack hole 48 on the sieve frame 3 under the elastic force of the spring 44 between the stop block 45 and the vertical bar 42.
[0033] Refer to Figures 1-2 and Figures 4-5 As shown, specifically, the support structure 5 includes a first positioning block 52 and a second positioning block 55 fixedly connected to the surface of the sieve frame 3. A sliding pin 53 is slidably connected inside the first positioning block 52, and the other end of the sliding pin 53 is fixedly connected with a rectangular bar 51. The sliding of the sliding pin 53 inside the first positioning block 52 plays a role in restricting the moving direction of the rectangular bar 51. A driving rod 56 is threadedly connected inside the second positioning block 55, and the driving rod 56 is rotatably connected to the inside of the rectangular bar 51. By rotating the driving rod 56 inside the second positioning block 55, the driving rod 56 will push the rectangular bar 51 to support a plurality of pull blocks 47 simultaneously. A ball 54 is embedded inside the pull block 47. By providing the ball 54, the friction force when relative movement occurs between the pull block 47 and the rectangular bar 51 is reduced.
[0034] Working principle: During the use of the vibrating screen, when there is a phenomenon of stones getting stuck on the vibrating screen, the pull block 47 can be pulled. The pull block 47 will drive the pin 43 to slide inside the longitudinal bar 42. After the pin 43 slides out from the inner side of the jack 48, the screen frame 3 and the longitudinal bars 42 on the cross bar 41 can be slid. When a certain gap is pulled out between the two longitudinal bars 42, the work of easily removing the stuck stones can be realized, thus facilitating the dredging work of the screen mesh. After moving the longitudinal bar 42 to a suitable position, the pull block 47 is released. At this time, the pin 43 will be inserted into the inner side of the corresponding jack 48 on the screen frame 3 under the elastic force of the spring 44 between the stop block 45 and the longitudinal bar 42, so as to realize the locking and fixing work of the longitudinal bar 42 after movement. By setting the auxiliary head 46 with a frustum-shaped structure, the efficiency of the pin 43 inserted into the inner side of the jack 48 is improved. Arranging the longitudinal bars 42 by inserting them into the inner sides of different jacks 48 can also realize the adjustment work of the tightness of the longitudinal bars 42 on the screen mesh, facilitating the screening work of stones of different sizes. By setting the anti-clamping structure 4, the phenomenon that it is inconvenient to clean the stones stuck inside the screen mesh is avoided. Through the flexible sliding work of the longitudinal bars 42 on the cross bar 41, the work of easily dealing with the stuck stones is facilitated, and to a certain extent, the use efficiency of the vibrating screen is improved.
[0035] When it is necessary to move the longitudinal bar 42, rotate the drive rod 56 inside the second positioning block 55. The drive rod 56 will push the rectangular bar 51 to support multiple pull blocks 47 at the same time. The sliding pin 53 slides inside the first positioning block 52 to play a role in restricting the moving direction of the rectangular bar 51. After supporting multiple pull blocks 47 at the same time, the pull block 47 will drive the pin 43 to be pulled out from the inner side of the jack 48. At this time, the flexible sliding work of the longitudinal bars 42 on the cross bar 41 can be realized, further improving the dredging efficiency of the stones stuck between adjacent longitudinal bars 42. By setting the ball 54, the friction force when the relative movement occurs between the pull block 47 and the rectangular bar 51 is reduced, facilitating the movement work of the longitudinal bar 42. By setting the support structure 5, the work of supporting multiple pull blocks 47 at the same time is facilitated, and then the adjustment work of multiple longitudinal bars 42 at the same time is facilitated, further improving the dredging effect of the screen mesh.
