Description

Technical Field

[0001] The utility model relates to the technical field of ore screening equipment, in particular to a screening equipment used in ore mining. Background Art

[0002] The process of separating loose materials into different particle sizes through a sieve is called ore screening. In a ore dressing plant, screening is often combined with the testing machine. Before the ore enters a certain section of the crusher, the qualified simple ore with a particle size that meets the requirements is called pre-screening. It can prevent the ore from being over-crushed and improve the production efficiency of the crusher. Among the existing ore screening equipment and methods, vibration screening is generally used;

[0003] The utility model patent with publication number CN 208373555 U in the prior art proposes a screening device for ore mining, which is provided with a screening plate. When the screening plate is shaken, it can effectively screen the ore, and the filter screen can screen the ore again, thereby realizing multiple screening, improving the screening effect, and being convenient to use. By separating the connecting rod from the receiving box, opening the door to take out the receiving box, the ore in the receiving box can be used, which can meet the needs of different users, and at the same time, it is convenient to replace the filter screen, which is convenient to use; however, it does not have the guiding ability when the device is unloading. If the ore is all put into the device through the feeding funnel, the ore will be piled up in the same position, which will not only easily cause blockage but also affect the service life of the screen plate. At the same time, it does not have the ability to reduce shock and noise of the device. During use, the vibration of the device will cause greater noise and wear. Therefore, we need to upgrade and transform it on the basis of the existing technology to overcome its problems and shortcomings. Utility Model Content

[0023] like Figure 1 -4, the present embodiment provides a design of a screening device for ore mining, including a device body 1, the device body 1 includes a screening box 2 and a support plate 18, a feed port 4 is arranged on the top of the screening box 2, a first screen 5 is arranged inside the screening box 2, a guide plate 9 is rotatably arranged on the upper end of the screening box 2, a main gear 10 is arranged on one end of the guide plate 9 and the main gear 10 is rotatably located on the back of the screening box 2, a fixing frame 11 is arranged on the back of the screening box 2 and a motor 12 is installed on the fixing frame 11, a half gear 13 is fixed on the front end of the motor 12 and a gear ring 14 is meshed on the outer side of the half gear 13, a rack rod 15 is fixed on the lower end of the gear ring 14 and the rack rod 15 and the main gear 10 are meshed with each other, a hollow column 19 is fixed on the center of the upper end of the support plate 18, a rubber sleeve 20 is fixed on the top of the hollow column 19 and a valve core 21 is arranged on one side, and the rubber sleeve 20 is connected to the bottom of the screening box 2.

[0024] Preferably, a box door 3 is provided on the front of the screening box 2, a collecting box 8 is provided at the bottom end of the inside of the screening box 2, a second screen 6 is provided at the lower end of the first screen 5, vibrators 7 are provided on the outer sides of the first screen 5 and the second screen 6 respectively, guide rods 16 are provided on both sides of the gear ring 14, guide grooves 17 are opened on the fixed frame 11 and the guide grooves 17 correspond to the guide rods 16, the collecting box 8 is used to facilitate the placement of the screening material, the two groups of screens are used to facilitate the secondary screening of the ore, and the cooperation of the guide rods 16 and the guide grooves 17 is used to facilitate the limitation of the movement of the gear ring 14.

[0025] Preferably, a rubber pad 22 is provided at the bottom of the support plate 18, four groups of springs 23 are provided at the upper end of the support plate 18, a top plate 24 is provided at the upper end of the spring 23, and the top plate 24 is fixed to the lower end of the screening box 2. The rubber pad 22 facilitates the placement and protection of the support plate 18, and the cooperation of the spring 23 and the top plate 24 facilitates the auxiliary shock absorption and buffering of the screening box 2.

[0026] The use principle and use process of the utility model are as follows: when in use, the ore is first put into the screening box 2 through the feed port 4, and the first screen 5 and the second screen 6 are controlled to work respectively by the vibrator 7. The first screen 5 screens the ore once, and the screened ore falls on the second screen 6, which is screened twice by the second screen 6. Finally, the ore falls into the collection box 8. At this time, the motor 12 controls the rotation of the half gear 13, and the half gear 13 drives the gear ring 14 to reciprocate along the direction of the guide groove 17. The gear ring 14 drives the lower end rack rod 15 to move synchronously, and the rack rod 15 carries The main gear 10 and the guide plate 9 move synchronously. At this time, the ore entering the screening box 2 through the feed port 4 is continuously guided by the guide plate 9 to any position on the surface of the first screen 5, which effectively prevents the ore from accumulating below the feed port 4. During the operation of the device, the vibration is transmitted to the rubber sleeve 20. Through the air pressure between the rubber sleeve 20 and the hollow column 19, the frequency vibration of the screening box 2 is buffered and absorbed by the rubber sleeve 20. At the same time, the spring 23 and the top plate 24 are used to assist in buffering and shock absorption, so as to avoid problems such as the rubber sleeve 20 being subjected to greater force, resulting in a reduced service life or greater wear.
