Technical Field

[0001] This utility model relates to the field of screening equipment, specifically a vibrating screen for mining. Background Technology

[0002] Mineral resources, also known as mineral deposits, refer to aggregates of minerals or useful elements formed through geological mineralization processes. They are naturally occurring within the Earth's crust or on the surface, either buried underground or exposed on the surface, and exist in solid, liquid, or gaseous states, possessing development and utilization value. Mineral resources are non-renewable resources, and their reserves are limited.

[0003] After mining, minerals need to be screened by size to separate small particles. Larger particles need to be crushed for further processing. However, existing screening equipment is difficult to perform multi-stage screening and requires multiple screenings using different sizes of equipment, which reduces screening efficiency. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0006] The screening mechanism includes a first screen, a second screen, a trough, and a vibration assembly. The trough is located on the housing. The first screen and the second screen are slidably disposed inside the trough on the upper and lower sides, respectively. In use, the ore to be screened is placed on the first screen, and the vibration assembly causes the first and second screens to vibrate, allowing the ore to be screened quickly. The fragments that pass through the mesh fall onto the conveyor belt and are transported to the outside of the housing. At the same time, the first screen and the second screen work together to perform multiple screening operations at once, greatly improving the screening efficiency.

In use, the motor drives the cam to rotate. When the cam protrusion presses against the connecting plate, it drives the first and second screens to move inside the trough, compressing the spring. When the cam protrusion moves away from the connecting plate, the spring returns to its original position, driving the first and second screens to return to their original position. This process is repeated to drive the first and second screens to vibrate, thereby improving screening efficiency.

[0008] Preferably, the first discharge mechanism includes a first discharge port and a first guide plate. The first discharge port is opened on one side of the housing, and the first guide plate is fixed on one side of the housing. In use, the ore material larger than the mesh size of the first screen is discharged through the first discharge port and then guided by the first guide plate to facilitate the discharge of the ore material.

[0009] Preferably, the second discharge mechanism includes a second discharge port and a second guide plate, the second discharge port being opened on one side of the housing, and the second guide plate being fixed on one side of the housing.

[0010] Preferably, there are two grooves, one at the top and one at the bottom.

[0011] Preferably, the mesh size of the first screen is larger than that of the second screen.

[0012] Preferably, one side of the cam is in close contact with the outside of the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In use, the mineral material to be screened is placed on the first screen, and the vibration mechanism causes the first screen and the second screen to vibrate, so that the mineral material is quickly screened. The broken material that passes through the mesh falls onto the conveyor belt and is transported to the outside of the shell. At the same time, the first screen and the second screen work together to perform multiple screenings at one time, which greatly improves the screening efficiency.

[0015] 2. When this utility model is in use, the motor drives the cam to rotate. When the cam protrusion presses against the connecting plate, it drives the first screen and the second screen to move inside the groove, compressing the spring. When the cam protrusion moves away from the connecting plate, the spring returns to its original position, driving the first screen and the second screen to return to their original position. This process is repeated to drive the first screen and the second screen to vibrate, thereby improving the screening efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a vibrating screen for mining, including a shell 1, a screening mechanism inside the shell 1, a first discharge mechanism and a second discharge mechanism on the outside of the shell 1, and a conveyor belt 3 for convenient transportation at the lower end of the shell 1;

[0022] The screening mechanism includes a first screen 2, a second screen 12, a trough 13, and a vibration assembly. The trough 13 is located on the housing 1. There are two troughs 13, one above the other. The first screen 2 and the second screen 12 slide inside the upper and lower sides of the trough 13, respectively. The mesh size of the first screen 2 is larger than that of the second screen 12. In use, the ore to be screened is placed on the first screen 2. The vibration assembly causes the first screen 2 and the second screen 12 to vibrate, which makes the ore be screened quickly. The broken material that passes through the mesh falls onto the conveyor belt 3 and is transported to the outside of the housing 1. At the same time, the first screen 2 and the second screen 12 work together to perform multiple screening operations at once, which greatly improves the screening efficiency.

[0023] The vibration assembly includes a support base 11, a motor 10, a cam 9, a spring 8, and a connecting plate 7. The support base 11 is fixed to one side of the housing 1 by bolts. The motor 10 is fixed to the top of the support base 11 by a mounting bracket. The cam 9 is fixed to the output end of the motor 10 by a coupling. The connecting plate 7 is welded and fixed to the outside of the first screen 2 and the second screen 12. The spring 8 is welded and fixed between the connecting plate 7 and the housing 1. One side of the cam 9 is close to the outside of the connecting plate 7. In use, the motor 10 drives the cam 9 to rotate. When the protruding end of the cam 9 presses against the connecting plate 7, it drives the first screen 2 and the second screen 12 to move inside the tank 13, pressing the spring 8. When the protruding end of the cam 9 moves away from the connecting plate 7, the spring 8 returns to its original position, driving the first screen 2 and the second screen 12 to return to their original position. This process is repeated to drive the first screen 2 and the second screen 12 to vibrate, thereby improving the screening efficiency.

[0024] The first discharge mechanism includes a first discharge port 5 and a first guide plate 6. The first discharge port 5 is located on one side of the housing 1, and the first guide plate 6 is welded and fixed to one side of the housing 1. In use, ore materials larger than the mesh size of the first screen 2 are discharged through the first discharge port 5 and then guided by the first guide plate 6 to facilitate the discharge of ore materials.

[0025] The second discharge mechanism includes a second discharge port 14 and a second guide plate 4. The second discharge port 14 is opened on one side of the housing 1, and the second guide plate 4 is welded and fixed on one side of the housing 1. During use, the ore material larger than the second screen 12 is discharged through the second discharge port 14 and then guided by the second guide plate 4 to facilitate the discharge of the ore material.

[0026] Working principle: During use, the ore to be screened is placed on the first screen 2. The vibration mechanism causes the first screen 2 and the second screen 12 to vibrate, so that the ore is quickly screened. The broken material that passes through the mesh falls onto the conveyor belt 3 and is transported to the outside of the housing 1. At the same time, the first screen 2 and the second screen 12 perform multiple screening operations at once, which greatly improves the screening efficiency. During use, the motor 10 drives the cam 9 to rotate. When the cam 9 protrudes and presses the connecting plate 7, it drives the first screen 2 and the second screen 12 to move inside the trough 13, compressing the spring 8. When the cam 9 protrudes away from the connecting plate 7, the spring 8 returns to its original position, driving the first screen 2 and the second screen 12 to return to their original position. This process is repeated to drive the first screen 2 and the second screen 12 to vibrate, thereby improving the screening efficiency.
