[0005] 1. The stone slag screening device for soil remediation disclosed in the patent with the publication number CN218281890U needs to be stopped during use, so as to clean the stone slag that stays on the screen a and the screen b, otherwise the stone slag that is not screened on the screen a and the screen b will be cleaned out by the flat push plate, thereby affecting the screening quality of the stone slag, and the work efficiency is reduced due to the stoppage;

[0006] 2. The stone slag screening device for soil remediation disclosed in the patent with the publication number CN218281890U needs to control the limiting steel plate to push the flat push plate to clean the stone slag that stays on the screen a and the screen b during use, and the actuator also needs to be controlled, thereby increasing the working steps when cleaning the stone slag and increasing the workload of the user;

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0039] Please see Figures 1 to 14 As shown, the present invention is a multi-stage screening device for mine waste rock and slag, including an external component 4, a top component 2 connected to the upper side of the external component 4, an internal component 6 evenly distributed inside the external component 4, a separator component 1 connected to the lower middle of both the top component 2 and the internal component 6, a filter component 7 symmetrically connected to the upper left and right sides inside the internal component 6, and a vibration component 8 connected to the upper middle of both the front and rear sides of the internal component 6.

[0040] Specifically, the multi-stage screening equipment for mine waste rock and slag performs the following screening steps: The user uses external screws to securely lock the support component 5 onto the working surface, activates the vibration component 8, and guides the mine waste rock and slag to be screened from the top component 2 into the outer component 4. The mine waste rock and slag inside the outer component 4 falls onto the filter component 7 on the inner component 6. The filter component 7 performs multiple screenings on the mine waste rock and slag, thus achieving graded screening. When the user needs to discharge the mine waste rock and slag remaining on the filter component 7, the user activates the separating component 1, which separates the upper part of the inner component 6. The filter assembly is divided into two parts. The user pulls out the T-shaped plug 43, and the mine waste rock and slag remaining on the upper part of the filter assembly 7 enters the collection frame placed on the L-shaped support plate 53 through the discharge pipe 44. The filter assembly 7 on the other side of the upper part of the inner component 6 continues to perform multi-stage screening of the mine waste rock and slag to be screened. The user opens the valve 491, and the mine waste rock and slag on the lower part of the outer component 4 enters the collection frame through the discharge pipe 49. After the mine waste rock and slag remaining on the filter assembly 7 are finished, the user starts the separator assembly 1 again until the first baffle 11 returns to its original position, and the entire upper part of the inner component 6 performs multi-stage filtration of the mine waste rock and slag to be screened.

[0041] Among them, such as Figure 1 , 2 As shown in Figure 3, the external component 4 includes a first support leg 41 and an upper opening frame 46; the lower side of the upper opening frame 46 is connected to the second support leg 42 and the first support leg 41 from left to right; the front side of the upper opening frame 46 is provided with a second rectangular groove 47 at equal intervals; the front side of the second rectangular groove 47 is provided with a limit groove 48; the rear inner wall of the upper opening frame 46 is provided with a support groove 45 at equal intervals; the upper opening frame 46 is connected to a discharge pipe 44 at equal intervals on one side; the discharge pipe 44 is filled with a T-shaped plug 43 on one side; the lower side of the upper opening frame 46 is connected to a discharge pipe 49; and a valve 491 is connected to the discharge pipe 49.

[0042] Specifically, the user places the collection box on the upper part of the horizontal plate 51, aligning the discharge pipe 49 with the collection box. The user opens the valve 491, and the mine waste rock and slag inside the lower side of the upper opening frame 46 enters the discharge pipe 49. The mine waste rock and slag inside the discharge pipe 49 enter the collection box on the horizontal plate 51.

[0043] Among them, such as Figure 1 , 4As shown in Figures 5, 6, and 7, the top assembly 2 includes a top cover 21 and a feed hopper 23. The top cover 21 is located on the upper side of the upper opening frame 46. Bolts 22 are threaded to the four corners of the upper part of the top cover 21. The feed hopper 23 is connected to the other side of the upper part of the top cover 21. A first mounting hole 211 is opened in the middle of the upper part of the top cover 21. A first limiting hole 212 is opened on the upper side of the first mounting hole 211. A first heat dissipation hole 213 is opened on the inner side wall of the first mounting hole 211. A first rectangular groove 24 is opened in the middle of the lower part of the top cover 21.

[0044] Specifically, the user feeds the waste rock and slag to be screened into the feed hopper 23. The waste rock and slag to be screened inside the feed hopper 23 enters the upper opening frame 46. The waste rock and slag to be screened inside the upper opening frame 46 falls onto the internal component 6.

[0045] Among them, such as Figure 2 , 8 As shown in 9, 10, and 14, the internal component 6 includes a plug rod 61 and a lower opening box 63. The lower opening boxes 63 are evenly distributed inside the upper opening frame 46. The upper part of the lower opening box 63 is symmetrically provided with a first through groove 62. The upper middle part of the lower opening box 63 is provided with a second placement hole 632. The upper side of the second placement hole 632 is provided with a second limiting hole 631. The inner side wall of the second placement hole 632 is provided with a second heat dissipation hole 633. The upper side of the lower opening box 63 is symmetrically provided with a second U-shaped groove 66. The upper middle part of the front and rear sides of the lower opening box 63 is provided with a placement hole body 64. The middle part of the front side of the lower opening box 63 is provided with a second through groove 65. The lower opening box 63 is symmetrically connected with plug rods 61 on the rear side. The plug rods 61 are inserted into the support groove 45.

[0046] The front side of the internal component 6 is connected to the limiting component 3, which includes a rectangular baffle 32 and a rectangular plug 33; the lower front part of the rectangular baffle 32 is connected to a protruding handle 31, the rectangular baffle 32 is located inside the limiting groove 48, the rear side of the rectangular baffle 32 is connected to the rectangular plug 33, the rear side of the rectangular plug 33 is provided with a first U-shaped groove 34, and the rectangular plug 33 is located inside the front side of the second rectangular groove 47.

[0047] Specifically, a door lock is connected to the front of the limiting component 3. The user opens the door lock with a key. The user applies an external force to the protruding handle 31 away from the upper opening frame 46. The rectangular baffle 32 moves away from the interior of the limiting groove 48, the rectangular plug 33 moves away from the interior of the second rectangular groove 47, the lower opening box 63 moves away from the interior of the upper opening frame 46, and the insert rod 61 moves away from the interior of the support groove 45. The lower opening box 63 and the upper opening frame 46 gradually separate, that is, the internal component 6 and the external component 4 gradually separate; conversely, the internal component 6 is connected to the interior of the external component 4.

[0048] Among them, such as Figure 8, 11 As shown, the filter assembly 7 includes a U-shaped edge 71 and a filter screen 72; the lower part of one side of the filter screen 72 is connected to the U-shaped edge 71, the U-shaped edge 71 is slidably connected to the second U-shaped groove 66, and the filter screen 72 is located inside the upper side of the first through groove 62.

[0049] Specifically, the aperture of the filter screen 72 inside the upper opening frame 46 decreases from top to bottom. The waste rock and slag to be screened that fall onto the internal component 6 are filtered multiple times by the filter screen 72 inside the upper opening frame 46, that is, the waste rock and slag to be screened are graded and screened.

[0050] When the user removes the internal component 6 from the external component 4, the user places the U-shaped edge 71 facing downwards. Due to its weight, the U-shaped edge 71 moves downwards and disengages from the second U-shaped groove 66. The filter screen 72 moves downwards with the U-shaped edge 71 and disengages from the first through groove 62, thus completing the separation between the internal component 6 and the filter component 7. Conversely, the filter component 7 is connected to the internal component 6.

[0051] Among them, such as Figure 8 , 13 As shown, the vibration assembly 8 includes a ventilation plate 81 and a vibration motor 83; a second base 82 is connected to the rear side of the vibration motor 83, and the second base 82, the vibration motor 83 and the ventilation plate 81 are distributed from the inside to the outside inside the mounting hole body 64.

[0052] Specifically, the user starts the vibration motor 83 via the external control terminal, causing the lower open box 63 to vibrate, the U-shaped edge 71 to vibrate, and the filter screen 72 to vibrate. The waste rock and slag to be screened on the filter screen 72 are in an active state, filtering the waste rock and slag to be screened on the filter screen 72; or, the waste rock and slag remaining on the filter screen 72 enter the discharge pipe 44.

[0053] Among them, such as Figure 1 , 4 As shown in Figures 1 and 12, the separating component 1 includes a first baffle 11 and a first motor 14; the upper side of the first motor 14 is connected to a first base 13, the lower side of the first motor 14 is connected to a lead screw 15, the upper side of the lead screw 15 is connected to a ball sleeve 12, the upper middle part of the first baffle 11 has a through hole 16, the ball sleeve 12 is located inside the upper side of the through hole 16, the lead screw 15 passes through the through hole 16, the first motor 14 is located inside the first mounting hole 211 and the second mounting hole 632 respectively, and the first baffle 11 is located inside the first rectangular groove 24 and the second through groove 65 respectively.

[0054] Specifically, when the user needs to discharge the mine waste rock and slag remaining on the filter screen 72, the user starts the first motor 14 using the external control terminal. The lead screw 15 and the ball sleeve 12 move downward along the lead screw 15, and the first baffle 11 moves downward until the lower side of the first baffle 11 contacts the middle of the upper part of the lower opening box 63. The upper part of the lower opening box 63 is divided into two parts, that is, the mine waste rock and slag remaining on the filter screen 72 is discharged on one side of the upper part of the lower opening box 63, and the mine waste rock and slag to be screened continues to be filtered on the other side of the upper part of the lower opening box 63. When it is not necessary to discharge the mine waste rock and slag remaining on the filter screen 72, the user starts the first motor 14 again, and the first baffle 11 moves upward back to its original position.

[0055] Among them, such as Figure 1 , 3 As shown, the lower side of the external component 4 is connected to the support component 5, which includes a horizontal plate 51 and a support frame 52; the upper side of the horizontal plate 51 is connected to the support frame 52, and the other side of the support frame 52 is provided with L-shaped support plates 53 at equal intervals. The upper side of the L-shaped support plates 53 is symmetrically connected with baffles 54, and the other upper side of the horizontal plate 51 is connected to the second support leg 42 and the first support leg 41 from left to right.

[0056] Specifically, the user places the collection box on the upper side of the L-shaped support plate 53, and the user pulls the T-shaped plug 43 out from the inside of the discharge pipe 44. The mine waste rock and slag remaining on the filter screen 72 enter the inside of the discharge pipe 44, and the mine waste rock and slag inside the discharge pipe 44 enter the inside of the collection box.

[0057] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
