DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 4 , this embodiment provides a technical solution: a vibrating screen dust reduction device, comprising a bracket 1 and a convenient dust prevention mechanism 3;

[0023] The support 1 has two guide rails, one for each of which is provided with a plurality of guide rails, and the other for each of which is provided with a plurality of guide rails. The support 1 has two guide rails, one for each of which is provided with a plurality of guide rails. The support 1 has two guide rails, one for each of which is provided with a plurality of guide rails.

[0024] The convenient dust-proof mechanism 3 includes a slide rail 31, a slide rod 32, a dust-proof cloth 33 and a driving handle 34. The slide rails 31 are respectively arranged at the left and right ends of the screening bin 2. The slide rails 31 are slidably connected to the slide rod 32 inside. The two longitudinally adjacent slide rods 32 are fixedly connected with the dust-proof cloth 33. The left and right ends of the slide rod 32 are fixedly connected to the driving handle 34. The convenient dust-proof mechanism 3 also includes a rib groove 35 and a positioning plate 36. The rib grooves 35 are respectively arranged inside the slide rails 31. The positioning plates 36 are respectively fixedly connected to the left and right ends of the slide rod 32. The positioning plates 36 are slidably connected to the inside of the rib grooves 35. The convenient dust-proof mechanism 3 also includes a notch 37 and a handle 38. The notch 37 is respectively arranged in the middle of the upper surface of the slide rail 31. The upper end of the slide rod 32 at the upper end is fixedly connected with a symmetrically distributed handle 38.

[0025] The locking plates 43 are inserted into the locking holes 42 and the locking plates 43 are fitted with the corresponding ends of the vertically adjacent slide bars 32 so that the slide bars 32 can pass through the recesses 37 in order to enter between the two slide rails 31. Then, the driving handle 34 is used to make the front and rear slide bars 32 slide toward the corresponding ends of the slide rails 31. At the same time, the positioning plates 36 slide in the corresponding rib grooves 35 to provide a limit for the sliding of the slide bars 32. The locking plates 43 cooperate with the vertically adjacent locking seats 41 to lock the positions of the front and rear sliding bars 32. The front and rear sliding bars 32 tighten the dustproof cloth 33, thereby realizing the rapid installation of the dustproof unit. After the screening is completed, the personnel turns off the vibration motor 8 by the control switch 10, and then removes the locking plates 43 in sequence. Then, the personnel pulls the upper end sliding bar 32 upward through the handle 38, and the upper end sliding bar 32 moves out of the slide rails 31 through the notch 37. The upper end sliding bar 32 moves up and pulls the corresponding sliding bar 32 upward through the dustproof cloth 33, and then moves out through the notch 37 in sequence to replace the dustproof cloth 33, which is convenient for cleaning the dustproof cloth 33.

[0026] The working principle of the vibrating screen dust reduction device provided by the present invention is as follows: when working, the personnel first place the bracket 1 and the screening bin 2 and other mechanisms stably in the horizontal working area. After the placement is stable, the personnel sequentially pass the sliding rod 32 through the notch 37 and enter between the two slide rails 31, and then use the driving handle 34 to make the front and rear two slide rods 32 slide toward the corresponding ends of the slide rail 31. At the same time, the positioning plates 36 slide in the corresponding rib grooves 35 to provide a limit and guide for the sliding of the slide rod 32. The front and rear two slide rods 32 are slid into between the two laterally adjacent locking seats 41, and then the personnel insert the locking plates 43 into the corresponding locking holes 42. The locking plates 43 cooperate with the vertically adjacent locking seats 41 to realize the position locking of the front and rear two slide rods 32, and the front and rear two slide rods 32 realize the tightening of the dustproof cloth 33. This enables the quick installation of the dustproof unit, and then the personnel controls the switch 10 to operate the vibration motor 8. The mechanical force generated by the vibration motor 8 causes the screening bin 2 to move back and forth up and down, and the sliding seat 6 slides up and down under the guidance of the corresponding pillar 5, providing guidance and limiting for the reciprocating movement of the screening bin 2. At the same time, the spring 7 assists the reciprocating movement of the screening bin 2 to achieve vibration screening of the minerals. After the screening is completed, the personnel turns off the vibration motor 8 through the control switch 10, and then moves out the locking plate 43 in turn, and then the personnel pulls the upper end slide bar 32 upward through the handle 38, and the upper end slide bar 32 moves out between the slide rails 31 through the recess 37. The upper end slide bar 32 moves up and pulls the corresponding slide bar 32 upward through the dustproof cloth 33, and then moves out through the recess 37 in turn to replace the dustproof cloth 33, which is convenient for cleaning the dustproof cloth 33.

[0027] It is worth noting that the control switch 10 disclosed in the above embodiment is provided with a control button corresponding to the vibration motor 8 and controlling the switching thereof.
