Description

Technical Field

[0001] This utility model relates to the field of vibrating screening machine technology, specifically to a mining vibrating screening device. Background Technology

[0002] Screening is an important step in mineral processing. Before beneficiation methods such as jigging, flotation, and magnetic separation, screening can initially separate the ore according to particle size, separating smaller particles from the crusher and preventing these fine particles from entering the crusher. This can reduce the load on the crusher and improve crushing efficiency.

[0003] In existing vibrating screening devices, ore is fed onto the screen at once, resulting in a large amount of ore accumulating on the screen, which can easily cause clogging and affect screening efficiency. Moreover, the direct impact of ore on the screen can damage it. Utility Model Content

[0009] As an improvement: a groove is provided at the bottom of the baffle, a slider is provided at the top of the adjustment plate, the slider slides within the groove, and a silicone plate is adhered to the bottom of the adjustment plate.

[0010] As an improvement: the baffle plate has several equidistantly arranged fixing holes connected to the slide groove. The adjusting plate is fixedly installed on the baffle plate by fastening bolts passing through the fixing holes and connected to the slider. The baffle plate is made of iron plate, and a magnet is provided on the top of the adjusting plate.

[0011] As an improvement: the vibration mechanism includes a vibration motor fixedly mounted on one side of the screening box, and fixed seats 1 arranged symmetrically on the front and rear sides of the screening box.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0027] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Combined with appendix Figure 1 , Figure 2 and Figure 4 As shown, a mining vibrating screening device includes a base 1, on which a screening box 2 is connected via a vibration mechanism. The screening box 2 has a screening trough 3, and a detachable screen 4 is connected inside the screening trough 3. A fixing plate 11 is symmetrically arranged in the screening trough 3, and the screen 4 is fixedly connected to the fixing plate 11 by bolts. This design facilitates the disassembly and replacement of the screen 4, ensuring screening quality. The vibration mechanism includes a vibration motor 18 fixedly mounted on one side of the screening box 2. The screening box 2 has a first fixing seat 19 symmetrically arranged on both the front and rear sides. A second fixing seat 20 is provided on the base 1 at a position corresponding to the first fixing seat 19. A vibration spring 21 is connected between the first fixing seat 19 and the second fixing seat 20.

[0029] The vibrating motor 18 can drive the screening box 2 to vibrate, and with the cooperation of the vibrating spring 21, the vibration of the screening box 2 is amplified, thereby realizing the screening operation of ore.

[0030] During ore screening, adding too much ore at once can easily cause clogging of screen 4, affecting screening quality. (This is in conjunction with the attached...) Figure 2As shown, a feeding trough 5 is connected to one side of the screening trough 3 on the screening box 2. The bottom of the feeding trough 5 is a sloping structure, and the outlet of the feeding trough 5 faces the screening trough 3. A material control component for controlling the material flow is provided at the outlet of the feeding trough 5. A discharge port 22 is opened on the side of the screening box 2 away from the feeding trough 5. The bottom of the screening box 2 is a sloping structure that slopes towards the discharge port 22, and the end near the discharge port 22 is lower.

[0031] Combined with appendix Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the material control assembly includes a baffle 6. The mounting frame 8 has an insertion port 10 that matches the size of the baffle 6. The baffle 6 is fixedly connected to the mounting frame 8 by bolts. The screening box 2 is provided with hydraulic cylinders 7 on both sides of the feeding trough 5. The extension ends of the two hydraulic cylinders 7 are connected to the mounting frame 8. The baffle 6 is connected to the mounting frame 8. Several adjustable plates 9 with adjustable spacing are connected to the bottom of the baffle 6. The bottom of the baffle 6 has a sliding groove 12. The top of the adjusting plate 9 has a slider 13. The slider 13 slides in the sliding groove 12. A silicone plate 14 is attached to the bottom of the adjusting plate 9. The silicone plate 14 prevents the adjusting plate 9 from directly contacting the bottom of the feeding trough 5, reducing the damage rate.

[0032] Among them, combined with the appendix Figure 5 and Figure 6 As shown, the baffle 6 has several equally spaced fixing holes 15 that are connected to the slide groove 12. The adjusting plate 9 is fixedly installed on the baffle 6 by passing through the fixing holes 15 with fastening bolts 16. The baffle 6 is made of iron plate, and the top of the adjusting plate 9 is provided with a magnet 17.

[0033] Before screening, the height of the baffle 6 is changed by the hydraulic cylinder 7. Then, according to the specific screening conditions, the distance between the adjusting plates 9 is slidably changed. After adjusting to the appropriate position, the fastening bolt 16 is inserted into the slider 13 through the fixing hole 15 to fix the position of the adjusting plate 9 and ensure the stability of the adjusting plate 9 during use. At the same time, the magnet 17 can be firmly attached to the iron baffle 6, further improving the installation firmness. The ore is put into the feeding trough 5. The inclined structure of the feeding trough 5 causes the ore to fall into the screen 4 through the opening between the adjusting plates 9 under the action of gravity and the vibration motor 18. The screen 4 screens out the ore that meets the standard and it falls to the bottom of the screening box 2. Since the bottom of the screening box 2 is a structure that slopes downward toward the discharge port 22, the ore is discharged from the discharge port 22 under the action of gravity.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
