[0019] (3) Through the operation of the fixed shell, screen plate and vibrating motor in the screening mechanism, the small-sized ore and ore powder that fall out from the inside of the shell will fall into the inside of the fixed shell, and the vibrating motor will drive the fixed shell to shake, thereby screening the small-sized ore and ore powder. The small-sized ore will be discharged from the first discharge port opened on the back of the fixed shell to the top of the third conveyor belt and transported. The ore powder will be discharged through the second discharge port opened at the bottom of the front surface of the fixed shell.

[0020] (4) Through the cooperation of the above devices, the ore can be screened during the transportation of ore, and the smaller ore and ore powder in the ore can be screened out and transported. Through the operation of the support mechanism, the support height of the transportation mechanism can be adjusted according to the usage requirements during actual use, thereby improving the overall flexibility of the equipment.

For fixing the bottom end of the outer casing 201, support plates 104 are fixed to the inner sides of the front surface and the back surface of the frame 101. The support plates 104 are used to support the servo motor 105 and the lead screw 106. The back of the support plate 104 on the left side of the back is connected to the servo motor 105 through a flange thread. The servo motor 105 is used to drive the lead screw 106 to rotate. The lead screw 106 is rotatably connected to the inner side of the support plate 104.

[0031] Example 2

[0032] Please see Figure 1 , Figure 2 and Figure 4As shown, based on Embodiment 1, a transport mechanism 2 is installed at the top of the support mechanism 1. The transport mechanism 2 includes a housing 201, a first conveyor belt 202, conveyor rollers 203, a second conveyor belt 204, a first protrusion 205, a protective shell 206, a first motor 207, and a baffle 208. The first conveyor belt 202 is rotatably connected to the left side of the interior of the housing 201. The first conveyor belt 202 is used to move the ore placed at its top. Multiple conveyor rollers 203 are rotatably connected to the center of the interior of the housing 201. While the multiple conveyor rollers 203 are used to move the ore that has moved to its top, smaller pieces of ore and ore powder will pass through multiple conveyor rollers 203. The gap between the conveyor rollers 203 causes ore to fall into the interior of the outer casing 201. A second conveyor belt 204 is rotatably connected to the right side of the interior of the outer casing 201. The second conveyor belt 204 is used to transport the ore after preliminary screening. A first protrusion 205 is fixed to the top inner side of the outer casing 201. The first protrusion 205 is used to enclose the outer sides of the first conveyor belt 202, conveyor rollers 203, and second conveyor belt 204 located at its bottom, preventing ore powder and small-sized slag from falling between the first conveyor belt 202, conveyor rollers 203, second conveyor belt 204 and the outer casing 201. A protective shell 206 is bolted to the front surface of the outer casing 201 to prevent... The protective shell 206 protects the chain sleeved on the outer wall of the drive shaft at the front end of the first conveyor belt 202, conveyor roller 203, and second conveyor belt 204. A first motor 207 is threadedly connected to the right side of the front surface of the protective shell 206 via a flange. The first motor 207 drives the rightmost drive shaft to rotate. A baffle 208 is fixedly attached to the center of the bottom end of the outer shell 201, which surrounds the ore and ore powder screened out from inside the outer shell 201. The outer shell 201 is fixedly attached to the top of the top plate 103 and supports the drive shafts of the first conveyor belt 202, conveyor roller 203, and second conveyor belt 204. The first protrusion 20... The bottom end of 5 is attached to the top of the outer wall of the first conveyor belt 202, the conveyor roller 203 and the second conveyor belt 204. Several discharge ports are evenly opened at the center of the bottom end of the outer shell 201. The discharge ports are used to discharge the smaller ore and ore powder screened out from the gap between the conveyor rollers 203. The front drive shafts of the first conveyor belt 202, the conveyor roller 203 and the second conveyor belt 204 all extend to the outer wall of the front surface of the outer shell 201. Chains are sleeved on the outer walls of multiple drive shafts. The output shaft of the first motor 207 is fixedly connected to the rightmost drive shaft through a coupling. Through the operation of the chain sleeved on the outer wall of the drive shaft, multiple drive shafts can be driven to rotate synchronously.

[0033] Example 3

[0034] Please see Figure 1 and Figure 5As shown, based on Embodiment 1 and Embodiment 2, a screening mechanism 3 is installed at the center of the support mechanism 1. The screening mechanism 3 includes a housing 301, a second motor 302, a transmission roller 303, a third conveyor belt 304, a second protrusion 305, a fixed housing 306, a sieve plate 307, and a vibrating motor 308. The second motor 302 is threadedly connected to the left rear end of the housing 301 via a flange. The second motor 302 drives the transmission roller 303 to rotate. Multiple transmission rollers 303 are rotatably connected to the bottom of the housing 301. Roller 303 drives the third conveyor belt 304 to rotate. The outer wall of the drive roller 303 is fitted with the third conveyor belt 304, which is used to transport the screened ore. A second protrusion 305 is fixedly connected to the bottom of the inner part of the housing 301. The second protrusion 305 is used to surround the outer side of the third conveyor belt 304. A fixed shell 306 is fixedly connected to the front end of the inner part of the housing 301 by a spring. The fixed shell 306 is used to support the screen plate 307. The screen plate 307 is fixedly connected inside the fixed shell 306. The screen plate 307 is used to screen the ore. Screening is performed to separate smaller ores and ore powder. A vibration motor 308 is fixed to the bottom of the fixed shell 306. The vibration motor 308 drives the fixed shell 306 to shake, which in turn drives the screen plate 307 to shake, screening the ores and ore powder that fall to the top of the screen plate 307. The shell 301 is fixed to the center of the frame 101 and supports the drive roller 303 and the fixed shell 306. The output shaft of the second motor 302 is connected to the rear drive roller 303 via a coupling. The left side of 3 is fixedly connected, and the fixed shell 306 is set at the bottom of the baffle 208. The top of the fixed shell 306 is provided with a feed port, and the bottom of the back and the bottom of the front surface of the fixed shell 306 are respectively provided with a first discharge port and a second discharge port. The first discharge port is used to discharge the smaller ore that has been screened, and the second discharge port is used to discharge the ore powder that has been screened. The screen plate 307 is provided with multiple screen holes evenly inside, and the screen plate 307 is inclined and set on the inner wall of the fixed shell 306. The ore powder can be screened through the screen holes.

[0035] The working principle of this invention is as follows: When the mining conveying equipment with screening function is put into use, the user puts the ore to be transported onto the top of the first conveyor belt 202 in the conveying mechanism 2, and at the same time connects the first motor 207 to an external power source through a connecting cable, so that the first motor 207 can start working. The operation of the first motor 207 can drive the rightmost drive shaft to rotate. Through the operation of the chain sleeved on the front end of the outer wall of multiple drive shafts, when one drive shaft rotates, it can synchronously drive the other drive shafts to rotate, thereby driving the first conveyor belt 202, the conveyor roller 203 and the second conveyor belt 204 to start working, so as to move the ore put on the top of the first conveyor belt 202. After the ore moves to the top of the multiple conveyor rollers 203, smaller ore pieces and ore powder mixed in will fall through the gaps between the conveyor rollers 203. The material is discharged from the inside of the outer shell 201 through the discharge port at the bottom of the outer shell 201 and falls into the fixed shell 306 in the screening mechanism 3. Through the operation of multiple conveying rollers 203 and the second conveyor belt 204, the ore can be initially screened and transported. The smaller ore and ore powder that fall into the fixed shell 306 can be shaken by the operation of the vibrating motor 308. Thus, through the operation of the screen plate 307, the smaller ore and ore powder that were originally mixed together can be screened apart, and the smaller ore is discharged from the first discharge port on the back of the fixed shell 306 and falls to the top of the third conveyor belt 304. Through the operation of the third conveyor belt 304, the smaller ore can be transported. At the same time, the ore powder at the screening point will be discharged through the second discharge port on the front surface of the fixed shell 306.

[0036] When transporting ore, the overall height of the conveying mechanism needs to be adjusted according to the usage to facilitate ore transport. When the overall height of the conveying mechanism 2 needs to be adjusted, the user connects the servo motor 105 in the support mechanism 1 to an external power source through a connecting cable, so that the servo motor 105 can start working. The operation of the servo motor 105 can drive the lead screw 106 to rotate. When one of the lead screws 106 rotates, it will drive the pulley fixed at its front end to rotate synchronously. In turn, the belt sleeved on the outer wall of the pulley will drive the other pulley to rotate, so that the two lead screws 106 can move synchronously. During the rotation of the lead screw 106, it will drive the threaded tube 107 threaded to its outer wall to move in the opposite direction. In turn, the threaded tube 107 will drive the sleeve 108 to move. When the sleeve 108 moves, it can lift the bottom end of the support rod 109. In turn, the support rod 109 can drive the top plate 103 to move, so that the overall height of the conveying mechanism 2 can be adjusted.

[0037] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
