Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, and particularly relates to a vibrating screen for crushing ores. Background Art

[0002] A vibrating screen is a device commonly used for screening and grading granular materials. It puts the materials onto the screen surface through a vibration excitation force to make them move and be screened. A vibrating screen usually consists of a screen box, a screen frame, a vibrator, a screen mesh, etc. The screen mesh has mesh holes with different apertures and can be screened and graded according to the requirements of the materials. Through the action of the vibration force, the materials are separated into particles on the screen surface to meet the required particle size requirements. Vibrating screens are widely used in fields such as mines, metallurgy, chemical engineering, and building materials. The patent with the publication number (CN110681576A) discloses a vibrating screen for crushing ores, including a frame, a screen frame arranged on the upper side of the frame, and a screen mesh installed in the screen frame. At a position on the upper side of the screen mesh far from the opening end of the screen frame, a transmission shaft is provided...... This patent protects the screen mesh by setting baffles on the screen frame to avoid hard collisions between the crushed stones and the screen mesh. However, the baffles need to be driven by a motor to rotate, which increases energy consumption. Moreover, after the baffles come into contact with the crushed stones, the crushed stones are likely to splash out, resulting in the falling out of the crushed stones and increasing the collection burden. Therefore, we introduce a vibrating screen for crushing ores. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a vibrating screen for crushing ores, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A vibrating screen for crushing ores includes a base. The front part of the upper end of the base is fixedly connected with a control cabinet. Four corners of the upper end of the base are fixedly connected with supports. The four supports are jointly connected with a screen frame. The middle part of the front end of the screen frame is fixedly connected with a vibration motor. The upper end of the base is fixedly connected with a splash-proof device. The upper part of the inner wall of the screen frame is fixedly connected with a buffer device. The middle part of the inner wall of the screen frame is fixedly connected with a screen mesh. The right end of the screen mesh is fixedly connected with a guide plate. The buffer device is located above the screen mesh, and there is no contact between the buffer device and the screen mesh.

[0006] Preferably, the buffer device includes a contact plate. A plurality of through holes are opened at the upper end of the contact plate. Four corners of the lower end of the contact plate are fixedly connected with dampers. The contact plate is in a structure with a higher left side and a lower right side. Springs are sleeved on the outer surfaces of the four dampers. The lower ends of the four dampers are fixedly connected with connectors.

[0007] Preferably, the four connectors are all fixedly connected with the inner wall of the screen frame. The contact plate is located inside the screen frame, and there is no contact between the contact plate and the screen frame.

[0008] Preferably, the splash-proof device includes a first vertical plate, a first connecting plate is fixedly connected to the rear end of the first vertical plate, a splash-proof plate is fixedly connected to the rear end of the first connecting plate, a second connecting plate is fixedly connected to the rear end of the splash-proof plate, and a second vertical plate is fixedly connected to the rear end of the second connecting plate.

[0009] Preferably, a buffer pad is fixedly connected to the lower end of the splash-proof plate. Both the first vertical plate and the second vertical plate are fixedly installed at the upper end of the sieve frame. The splash-proof plate has a structure that is higher on the left and lower on the right.

[0010] Preferably, the splash-proof plate is located above the contact plate, and there is no contact between the splash-proof plate and the contact plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting the buffer device, the four connecting pieces are fixed to the inner wall of the sieve frame. When the crushed stones contact the contact plate, under the action of the four springs under the contact plate, the impact of the crushed stones can be buffered, so that the crushed stones fall onto the sieve mesh with a smaller impact. Moreover, the entire buffer device does not require additional energy supply and can work continuously without interruption, which is convenient for long-term use.

[0013] 2. By setting the splash-proof device, since the splash-proof plate is inclined, it partially shields the contact plate. Thus, after the crushed stones collide with the contact plate and splash, the splash-proof plate can shield the splashing crushed stones, thereby avoiding damage to personnel caused by the splashing of crushed stones. By setting the buffer pad on the splash-proof plate, the service life of the splash-proof plate can be extended and damage can be avoided. Description of the Drawings

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0023] A mining gravel vibrating screen includes a base 1. A control cabinet 3 is fixedly connected to the front part of the upper end of the base 1. Four supports 9 are fixedly connected to the four corners of the upper end of the base 1. The four supports 9 are jointly connected to a screen frame 8. A vibration motor 2 is fixedly connected to the middle of the front end of the screen frame 8. A splash-proof device 6 is fixedly connected to the upper end of the base 1. A buffer device 7 is fixedly connected to the upper part of the inner wall of the screen frame 8. A screen 5 is fixedly connected to the middle of the inner wall of the screen frame 8. A feeding plate 4 is fixedly connected to the right end of the screen 5. The buffer device 7 is located above the screen 5, and there is no contact between the buffer device 7 and the screen 5.

[0024] In this embodiment, the buffer device 7 includes a contact plate 71. A plurality of through holes 72 are formed in the upper end of the contact plate 71. Dampers 73 are fixedly connected to the four corners of the lower end of the contact plate 71. The contact plate 71 is in a structure with the left side higher than the right side. Springs 75 are sleeved on the outer surfaces of the four dampers 73. Connectors 74 are fixedly connected to the lower ends of the four dampers 73. The four connectors 74 are fixedly connected to the inner wall of the sieve frame 8. The contact plate 71 is located inside the sieve frame 8 and does not contact the sieve frame 8. The plurality of through holes 72 can facilitate small gravel to directly fall on the sieve mesh 5.

[0025] In this embodiment, the splash-proof device 6 includes a first vertical plate 61. A first connecting plate 64 is fixedly connected to the rear end of the first vertical plate 61. A splash-proof plate 63 is fixedly connected to the rear end of the first connecting plate 64. A second connecting plate 65 is fixedly connected to the rear end of the splash-proof plate 63. A second vertical plate 62 is fixedly connected to the rear end of the second connecting plate 65. A buffer pad 631 is fixedly connected to the lower end of the splash-proof plate 63. The first vertical plate 61 and the second vertical plate 62 are both fixedly installed on the upper end of the sieve frame 8.

[0026] It should be noted that the present utility model is a vibrating sieve for mining gravel. During use, the gravel is poured on the contact plate 71. When pouring, the gravel cannot be poured on the splash-proof plate 63 and needs to be poured on the contact plate 71 from the gap between the splash-proof plate 63 and the contact plate 71. When the gravel contacts the contact plate 71, under the action of the four springs 75 under the contact plate 71, the impact of the gravel can be buffered, so that the gravel falls onto the sieve mesh 5 with a smaller impact. When the gravel splashes when contacting the contact plate 71, since the contact plate 71 is inclined, the gravel splashes towards the splash-proof plate 63. At this time, the splash-proof plate 63 blocks the splashing gravel, thus avoiding damage to personnel caused by the splashing of the gravel. By providing the buffer pad 631 on the splash-proof plate 63, the buffer pad 631 can buffer the impact of the gravel, thereby improving the service life of the splash-proof plate 63 and avoiding damage.
