Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-8 , the present utility model provides a technical solution: a screening device for ores, including a mounting frame 1, a screening unit 2 provided at the upper end of the mounting frame 1 for screening ores, and an aggregate unit 3 provided on one side of the upper end of the mounting frame 1, further including:

[0030] A cleaning unit 5, provided at the lower end of the screening unit 2, for cleaning impurities on the screening unit 2;

[0031] The cleaning unit 5 includes:

[0032] The movable box 52 is adjustably arranged below the screening unit 2;

[0033] The cleaning member is telescopically arranged inside the movable box 52 and is used for cleaning the impurities on the screening unit 2;

[0034] The adjusting member is arranged on both sides of the movable box 52 and at the lower end of the screening unit 2 and is used for adjusting the installation position of the cleaning member.

[0035] It should be noted that during operation, the ore raw materials are added into the aggregate unit 3 by a forklift, and then the screening unit 2 is started to screen the ore falling onto the screening unit 2. After the screening work is completed, the movable box 52 is moved, and the cleaning member can clean the blocked impurities on the screening unit 2. Moreover, the installation position of the movable box 52 at the lower end of the screening unit 2 can be adjusted through the adjusting member, and the screening unit 2 can be cleaned in multiple directions, improving the cleaning efficiency of the screening unit 2, enabling the impurities on the screening unit 2 to be cleaned in a timely and effective manner, thereby ensuring the continuity of the screening process and the screening efficiency.

[0036] In one embodiment, the screening unit 2 includes a screening frame 21 fixed to the upper end of the mounting frame 1, a vibrating machine 23 fixed to the upper end of the screening frame 21, a screen 22 fixed inside the screening frame 21, and a buffer member 24 arranged at the lower end of the screening frame 21 and connected to the mounting frame 1. An outlet 211 is provided at the lower end of the screening frame 21.

[0037] With such a design, referring to Figures 1-5 , when the vibrating machine 23 is started, it drives the screening frame 21 to shake, and then the screen 22 can screen the ore. The stones with qualified particle sizes after screening are discharged from the outlet 211, and the smaller stones fall below the screen 22. Through the setting of the buffer member 24, the vibration generated during the screening process is effectively buffered, enhancing the stability of the device, reducing noise and wear at the same time, and improving the service life of the device.

[0038] In one embodiment, the cleaning member includes a hydraulic cylinder 55 fixed inside the movable box 52, a lifting plate 56 fixed to the upper end of the hydraulic cylinder 55, and a cleaning rod 57 fixed to the upper end of the lifting plate 56 and passing through the movable box 52. The cleaning rod 57 is arranged corresponding to the mesh holes of the screen 22.

[0039] With such a design, referring to Figure 4 and Figures 7-8, start the hydraulic cylinder 55 to drive the lifting plate 56 to move upward. Then, the cleaning rod 57 is inserted into the screen 22 to push out the impurities accumulated in the screen 22, which can keep the screen 22 unobstructed, improve the screening efficiency of the screen 22. After cleaning one unit of the screen 22, the hydraulic cylinder 55 drives the cleaning rod 57 to move downward, and then moves the moving box 52 one unit to clean the next unit of the screen 22, improving the cleaning efficiency of the screen 22.

[0040] In one embodiment, the adjusting member includes sliders 53 fixed on both sides of the moving box 52, a limiting frame 51 fixed at the lower end of the screening frame 21, and a limiting ring 54 arranged on the side of the slider 53 away from the moving box 52. A sliding groove 511 for the slider 53 to move is formed on the limiting frame 51.

[0041] With such a design, referring to Figure 4 , move the slider 53 so that the slider 53 moves inside the sliding groove 511. The limiting ring 54 can limit the installation position of the slider 53, making the moving box 52 move more smoothly under the screen 22.

[0042] In one embodiment, the limiting ring 54 is fixedly connected to the limiting frame 51 through a positioning rod 58. A fixing groove 512 for placing the positioning rod 58 is formed at the upper end of the limiting frame 51, and a positioning groove 541 for placing the positioning rod 58 is formed on the limiting ring 54. A handle 59 is arranged on one limiting ring 54.

[0043] With such a design, referring to Figure 5 , after the screen 22 is cleaned, hold the handle 59 and move the moving box 52 upward to the upper part of the limiting frame 51. Then, after aligning the positioning groove 541 with the fixing groove 512, insert the positioning rod 58 into the positioning groove 541 and the fixing groove 512 to fix the limiting ring 54 to the limiting frame 51, and then store the moving box 52 at the lower end of the screen 22.

[0044] In one embodiment, a blanking plate 4 is arranged at the position of the discharge port 211 of the mounting frame 1. The aggregate unit 3 includes a material guiding bin 31 arranged at the upper end of the screening frame 21, a hinge 33 arranged between the material guiding bin 31 and the screening frame 21, and a limiting frame 32 arranged at the upper end of the screening frame 21. The limiting frame 32 is arc-shaped and fixedly connected to the material guiding bin 31 through a fixing bolt. Limiting grooves 321 are spacedly formed on the limiting frame 32, and a blanking port 311 is formed at the lower end of the material guiding bin 31.

[0045] With such a design, referring to Figures 1-3 、and Figure 5, the aggregate unit 3 is designed such that the screened ore can be conveniently collected and guided to a designated position. Moreover, according to the actual installation position of the screening device, the installation angle of the material guiding bin 31 can be adjusted by adjusting the fixing position of the fixing bolts and the limiting groove 321, so that it is convenient to add the ore raw material into the interior of the material guiding bin 31, and it is also convenient for the ore raw material to fall from the discharge opening 311 onto the screen mesh 22 to continue the screening work, improving the work efficiency. At the same time, the setting of the discharge plate 4 also enables the ore to smoothly fall from the screening outlet, reducing the possibility of blockage and scattering.
