Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to an ore screening device for mining and smelting. Background Art

[0002] Vibrating screening machine is a screening equipment that can separate and screen ores of different specifications. It is used for ore processing and mineral processing and is widely used in screening work in the mining industry.

[0004] The above patent records the technical principle of a mining screening machine. In actual application, in order to extend the residence time of the ore on the screen plate, the length of the screen plate is designed to be relatively long to ensure screening efficiency, but it also leads to a larger overall specification of the screening machine, increasing transportation and storage costs. The functional structure of the screen plate can be further improved to extend the residence time of the ore, thereby improving the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an ore screening device for mining and smelting to solve the problems raised in the above background technology.

[0013] The utility model sets a material retarding device on the top surface of the screen plate. During use, the servo motor controls the screen plate to open and close regularly according to the settings. The specific working process is: when starting, the servo motor drives the transmission roller to rotate forward, so that the transmission roller controls the baffle to flip and lift upward. At this time, the baffle can stop the mineral material to prevent it from being discharged from the screen box too quickly, allowing the mineral material to continue to stay on the screen plate for screening, thereby improving the screening efficiency. When closing, the servo motor drives the transmission roller to reverse, so that the transmission roller controls the baffle to flip downward and cover the inner side of the connecting groove, thereby releasing the interception of the mineral material and allowing the mineral material to continue to pass.

[0020] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0021] See also Figure 1-5The utility model provides an ore screening device for mining and smelting, comprising a screen box 1, a screen plate 2, a discharge bucket 3 and a buffer device 4. The screen box 1 is paved with a sieve plate 2, the discharge bucket 3 is bolted to the bottom of the screen box 1, the discharge bucket 3 is connected to the inside of the screen box 1, and the top surface of the sieve plate 2 is provided with a buffer device 4.

[0022] The utility model provides an ore screening device for mining and smelting, wherein the material retarding device 4 includes a connecting groove 41, a transmission roller 42, a baffle 43, a roller shaft 44, a transmission wheel 45 and a servo motor 46. The top surface of the screen plate 2 is horizontally provided with a connecting groove 41, and the connecting groove 41 passes through both sides of the screen plate 2. The upper side wall of the connecting groove 41 is hingedly installed with a transmission roller 42, and the transmission roller 42 is equal to the length of the connecting groove 41. A baffle 43 is welded on the surface of the transmission roller 42, and the baffle 43 can be flipped into the inner side of the connecting groove 41 to cover it so that the ore can pass normally. A roller shaft 44 is integrally provided at the right end of the transmission roller 42, and a transmission wheel 45 is rotatably installed on the right wall of the screen box 1, and the roller shaft 44 passes through the screen box 1 and is connected to the transmission wheel 45, so that the transmission wheel 45 establishes a transmission connection with the transmission roller 42, and a servo motor 46 is installed on the right wall of the screen box 1, and the transmission wheel 45 is driven to rotate by the servo motor 46.

[0023] To further illustrate, the baffle 43 and the short side of the sieve plate 2 are equal in length, so that the baffle 43 can more effectively control the ore to stagnate on the sieve plate 2 for screening.

[0024] To further explain, the baffle 43 is made entirely of carbon steel, which has excellent plasticity and toughness, and high hardness, ensuring that the baffle 43 is not easily deformed by collision during use, thereby ensuring its service life.

[0025] It is further explained that the rotation angle range of the roller 44 is 30 to 60 degrees, so as to ensure that the roller 44 can lift the baffle 43 to a sufficient angle to intercept the mineral material.

[0026] It is further explained that the depth of the connecting groove 41 does not exceed 1 cm, and the lower side wall of the connecting groove 41 is sloped, so that the mineral materials accidentally falling into the connecting groove 41 can be discharged downward by themselves and are not easily stuck in the connecting groove 41.

[0027] Further explanation: the number of connecting grooves 41, transmission rollers 42, baffles 43, roller shafts 44 and transmission wheels 45 installed is 1 or more. When the number of transmission wheels 45 installed exceeds 1, a synchronous belt 47 is used to connect the transmission between the transmission wheels 45. The number of installed components can be designed and adjusted according to usage requirements.

[0028] Here’s how it works:

[0029] First, before use, the servo motor 46 is connected to the control system of the screening machine so that the servo motor 46 controls the opening and closing of the sieve plate 2 at a set time.

[0030] Second, when in use, the ore is poured into the screen box 1 from above, where the small-sized ore will be screened downward by the sieve plate 2 and discharged through the discharge hopper 3, while the large-sized ore will remain on the surface of the sieve plate 2 and eventually be discharged from the lower opening of the screen box 1 along the sieve plate 2, thereby realizing the sorting of the ore particle size.

[0031] Third, during use, the servo motor 46 controls the screen plate 2 to open and close at a set time according to the setting. The specific working process is: when starting, the servo motor 46 drives the transmission roller 42 to rotate forward, so that the transmission roller 42 controls the baffle 43 to flip and lift upward. At this time, the baffle 43 can stop the mineral material to prevent it from being discharged from the screen box 1 too quickly, allowing the mineral material to continue to stay on the screen plate 2 for screening, thereby improving the screening efficiency. When closing, the servo motor 46 drives the transmission roller 42 to reverse, so that the transmission roller 42 controls the baffle 43 to flip downward and cover the inner side of the connecting groove 41, thereby releasing the interception of the mineral material and allowing the mineral material to continue to pass.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
