[0002] Mining is an important raw material industry. Metal ores are the main raw materials for the smelting industry, while non-metallic ores are important chemical raw materials and building materials. Mining refers to the extraction and utilization of valuable natural mineral resources by means of manual labor or machinery. In addition, the size of the stones will vary during the mining process, so it is necessary to classify the stones.

[0003] According to patent number CN113751319A, an automatic stone sorting device for mining includes a cleaning device, a sorting device, and a storage device. The cleaning device includes a bearing plate, a support vertical plate, a perforated plate, a hydraulic press assembly, a rotating seat assembly, and a vibration assembly. The sorting device includes first and second fixed strips, first and second rotating shafts, first and second rotating rollers, first and second rotating wheels, first and second transmission belts, first and second rotating motors, and a guide plate assembly.

[0004] The mine uses an automatic stone sorting device. While it can shake off dust, clean, classify, and store stones of different sizes, it is not convenient to classify stones of different sizes when specific sorting operations are required. Therefore, this technical solution needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic stone sorting device and sorting method for mining, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic stone sorting device for mining, including a base plate, a feeding mechanism fixedly connected to the top of the base plate, an adjusting mechanism fixedly connected inside the feeding mechanism, and an angle mechanism fixedly connected to the right end of the top of the base plate. The adjusting mechanism includes a first motor, which is fixedly connected to the outside of the feeding mechanism. A worm gear is fixedly connected to one end of the first motor. A worm wheel is meshed with the surface of the worm gear. A lead screw is fixedly connected to the middle of one side of the worm wheel. A support plate is provided on the surface of the lead screw. A threaded block is threadedly connected to the surface of the lead screw. A sliding frame is rotatably connected to the top of the threaded block. A hinge bar is slidably connected inside the sliding frame. A sliding column is fixedly connected to the top of the hinge bar. A screen bar is provided on the surface of the sliding column. A slider is fixedly connected to both ends of the screen bar. A telescopic baffle is fixedly connected to both ends of the screen bar.

[0007] According to the above technical solution, the support plate has a through hole inside, and the surface of the lead screw passes through the through hole inside the support plate, so that the lead screw can rotate under the support of the through hole inside the support plate, thereby driving the threaded block to move and adjusting the gap between the screen bars to adjust the size of the material falling and classifying.

[0008] According to the above technical solution, a groove is provided at the bottom of the screen bar, and the surface of the sliding column is slidably connected to the inside of the groove.

[0009] According to the above technical solution, the feeding mechanism includes a vertical plate, which is fixedly connected to the top of the base plate. A feeding box is hinged to the top of the vertical plate. A second motor is fixedly connected to the left side of the feeding box. An electric rod is fixedly connected to the right end of the second motor. A feeding blade is fixedly connected to the surface of the electric rod. A dropping seat is fixedly connected to the top of the feeding box. A third motor is fixedly connected to the left side of the dropping seat. An electric rod is fixedly connected to the right end of the third motor. A movable plate is fixedly connected to the surface of the electric rod. A hopper is fixedly connected to the top of the dropping seat. The right side of the first motor is fixedly connected to the outside of the feeding box.

[0010] According to the above technical solution, the inside of the feeding box is provided with a sliding groove, and the surface of the slider is slidably connected to the inside of the sliding groove.

[0011] According to the above technical solution, a through hole is provided on the left side of the material dropping seat, and the surface of the electric rod passes through a sliding groove opened inside the long feeding box. The right end of the electric rod is rotatably connected to the right side inside the material dropping seat, so that the electric rod can move under the limiting action in the sliding groove inside the material dropping seat, thereby driving the movable plate to adjust the amount of stone dropping, and can control the amount of material dropping.

[0012] According to the above technical solution, the angle mechanism includes a fourth motor, which is fixedly connected to the top right end of the base plate. A threaded rod is fixedly connected to the top of the fourth motor. A rectangular block is threadedly connected to the surface of the threaded rod. Short bars are fixedly connected to both ends of the rectangular block. A connecting strip is provided on the surface of the short bars. An L-shaped seat is fixedly connected to the top of the threaded rod. The bottom of the L-shaped seat is fixedly connected to the top of the base plate.

[0013] According to the above technical solution, the connecting strip has a guide groove inside, the surface of the rectangular block is slidably connected to the inside of the guide groove, and straight grooves are respectively opened on both sides inside the guide groove. The surface of the short bar is located inside the straight groove, which facilitates the sliding of the rectangular block inside the guide groove. This allows the rectangular block to drive the feeding box to adjust its angle and control the speed of stone classification when it moves.

[0014] Another technical problem to be solved by the present invention is to provide an automatic classification method for mining stone, so as to solve the problems mentioned in the background art above; To achieve the above objectives, the present invention provides the following technical solution, comprising the following steps: S1: Stone feeding operation The stones to be sorted are fed from the top of the hopper. The material enters the machine from the top hopper and is vibrated by the vibrating feeder. The selected material falls down the chute. The material passes through the vibrator at the top of the chute and slides down the chute at an accelerated speed into the sorting box. The material that meets the requirements continues to fall into the finished product trough of the receiving hopper and flows out, so that the selected material achieves the purpose of fine selection. S2: Layering adjustment of stone materials during the dropping process Based on the size difference of the stone volume, when the material falls into the material box, the stones in different material boxes are classified and fall. Then, the stones with different volume differences are separated. Then, the gap size of three different feeding screens is adjusted. When the size of the stone corresponds to the corresponding gap during the continuous movement of the stone, the stone falls into the material box below through the gap, and the stones with different volume differences are screened out. S3: Adjustment during stone dropping The angle is adjusted according to the amount of stone falling. When there is too much stone, the angle of the device is adjusted to be as horizontal as possible, while when there is too little stone, the angle of the device is adjusted to be as tilted as possible.

[0015] According to the above technical solution, in step S, during the adjustment of the stone material, the adjustment angle of the device needs to be kept as stable as possible to avoid uneven classification of the stone material during the dropping process.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The automatic stone sorting device and sorting method for mining stone, through the setting of the adjustment mechanism, uses the sliding column to drive the internal gap distance of the screen bars to adjust the gap size between the screen bars, and can sort stones of different sizes and types when the stone is sorted and dropped.

[0017] 2. The automatic stone sorting device and sorting method for the mine, through the set feeding mechanism, when it is necessary to control the feeding of the falling material, the third motor is started to drive the electric rod to rotate, which in turn drives the movable plate to rotate inside the falling material seat, and thus controls the feeding amount of the falling material.

[0018] 3. The automatic stone sorting device and sorting method for mining stone, through the set feeding mechanism, the stone is put into the top of the hopper, and falls into the long feeding box through the movable plate and the dropping seat. The feeding blade rotates inside the long feeding box and pushes the stone inside forward, thereby facilitating the pushing of the stone.

[0019] 4. The automatic stone sorting device and sorting method for mining uses an angled mechanism to raise or lower the connecting strip, which in turn raises or lowers the feeding box. This allows for different rates of stone dropping and sorting based on the quantity of stone, resulting in higher efficiency and faster material dropping. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-5 The present invention provides a technical solution: Example 1:

[0024] An automatic stone sorting device for mining includes a base plate 1, a feeding mechanism 3 fixedly connected to the top of the base plate 1, an adjusting mechanism 2 fixedly connected inside the feeding mechanism 3, and an angle mechanism 4 fixedly connected to the top right end of the base plate 1. The adjusting mechanism 2 includes a first motor 21, which is fixedly connected to the outside of the feeding mechanism 3. A worm gear 22 is fixedly connected to one end of the first motor 21. A worm wheel 23 is meshed with the surface of the worm gear 22. A lead screw 24 is fixedly connected to the middle of one side of the worm wheel 23. A support plate 25 is provided on the surface of the lead screw 24. A threaded block 261 is threadedly connected to the surface of the lead screw 24. A sliding frame 262 is rotatably connected to the top of the threaded block 261. A hinge bar 263 is slidably connected inside the sliding frame 262. A sliding column 264 is fixedly connected to the top of the hinge bar 263. A screen bar 27 is provided on the surface of the sliding column 264. A slider 28 is fixedly connected to both ends of the screen bar 27. A telescopic baffle 29 is fixedly connected to both ends of the screen bar 27.

[0025] Furthermore, the support plate 25 has a through hole, the surface of the screw 24 passes through the through hole inside the support plate 25, the bottom of the screen bar 27 has a groove, the surface of the sliding column 264 is slidably connected to the inside of the groove, and the gap distance inside the screen bar 27 is adjusted by using the sliding column 264 to drive the screen bar 27, thereby adjusting the gap size between the screen bars 27, and different sizes and types of stones can be classified when the stones are sorted and dropped.

[0026] See Figure 1-7 Furthermore, based on Embodiment 1, the feeding mechanism 3 further includes a vertical plate 31, which is fixedly connected to the top of the base plate 1. A feeding elongated box 32 is hinged to the top of the vertical plate 31. A second motor 33 is fixedly connected to the left side of the feeding elongated box 32. An electric rod 34 is fixedly connected to the right end of the second motor 33. A feeding blade 351 is fixedly connected to the surface of the electric rod 34. A dropping seat 352 is fixedly connected to the top of the feeding elongated box 32. A third motor 36 is fixedly connected to the left side of the dropping seat 352. An electric rod 37 is fixedly connected to the right end of the third motor 36. A movable plate 38 is fixedly connected to the surface of the electric rod 37. A hopper 39 is fixedly connected to the top of the dropping seat 352. The right side of the first motor 21 is fixedly connected to the outside of the feeding elongated box 32. A sliding groove is opened inside the feeding elongated box 32, and the surface of the slider 28 is slidably connected to the inside of the sliding groove.

[0027] Furthermore, a through hole is provided on the left side of the material drop seat 352, and the surface of the electric rod 37 passes through the sliding groove opened inside the feeding box 32. The right end of the electric rod 37 is rotatably connected to the right side inside the material drop seat 352. When the feeding control of the material drop is required, the third motor 36 is started to drive the electric rod 37 to rotate, which in turn drives the movable plate 38 to rotate inside the material drop seat 352, and thus controls the feeding amount of the material drop. The stone is put into the top of the hopper 39 and falls into the feeding box 32 through the movable plate 38 and the material drop seat 352. The feeding blade 351 rotates inside the feeding box 32 and pushes the stone inside forward, which facilitates the pushing of the stone.

[0028] See Figure 1-7 Furthermore, based on Embodiment 1, the angle mechanism 4 further includes a fourth motor 41, which is fixedly connected to the top right end of the base plate 1. A threaded rod 42 is fixedly connected to the top of the fourth motor 41. A rectangular block 43 is threadedly connected to the surface of the threaded rod 42. Short rods 44 are fixedly connected to both ends of the rectangular block 43. A connecting strip 45 is provided on the surface of the short rods 44. An L-shaped seat 46 is fixedly connected to the top of the threaded rod 42. The bottom of the L-shaped seat 46 is fixedly connected to the top of the base plate 1.

[0029] Furthermore, the connecting strip 45 has a guide groove inside, the surface of the rectangular block 43 is slidably connected to the inside of the guide groove, and straight grooves are opened on both sides inside the guide groove. The surface of the short bar 44 is located inside the straight groove. The connecting strip 45 is raised or lowered, and drives the feeding box 32 to be raised or lowered. This allows for different rates of material dropping and classification according to the amount of stone, thereby improving the efficiency of material dropping and classification while also ensuring rapid material dropping.

[0030] This invention provides an automatic stone sorting device and method for mining to solve another technical problem, comprising the following steps: S1: Stone feeding operation The stones to be sorted are fed from the top of the hopper. The material enters the machine from the top hopper and is vibrated by the vibrating feeder. The selected material falls down the chute. The material passes through the vibrator at the top of the chute and slides down the chute at an accelerated speed into the sorting box. The material that meets the requirements continues to fall into the finished product trough of the receiving hopper and flows out, so that the selected material achieves the purpose of fine selection. S2: Layering adjustment of stone materials during the dropping process Based on the size difference of the stone volume, when the material falls into the material box, the stones in different material boxes are classified and fall. Then, the stones with different volume differences are separated. Then, the gap size of three different feeding screens is adjusted. When the size of the stone corresponds to the corresponding gap during the continuous movement of the stone, the stone falls into the material box below through the gap, and the stones with different volume differences are screened out. S3: Adjustment during stone dropping The angle is adjusted according to the amount of stone falling. When there is too much stone, the angle of the device is adjusted to be as horizontal as possible, while when there is too little stone, the angle of the device is adjusted to be as tilted as possible.

[0031] During the adjustment process of the stone material, the adjustment angle of the device should be kept as stable as possible to avoid uneven classification of the stone material during the dropping process.

[0032] The automatic stone sorting device and method for mining involves three discharge ports at the bottom of the feeding box 32, with three different discharge boxes corresponding to the bottom. The gap between each screen bar 27 gradually increases from left to right. All the stone is then fed from the top of the hopper 39, passing through the movable plate 38 and the discharge seat 352 into the feeding box 32. The second motor 33 is then started, driving the electric rod 34 to rotate inside the feeding box 32. The moving feed blade 351 rotates inside the feeding box 32 and pushes the stones inside forward. When the stones move to the top of the screen bar 27, under the action of gravity, the smaller stones fall into the screen bar 27 with smaller gaps and into the corresponding dropping box at the top of the bottom plate 1. When the feeding control of the dropping is required, the third motor 36 is started to drive the electric rod 37 to rotate, which in turn drives the movable plate 38 to rotate inside the dropping seat 352, thereby controlling the feeding amount of the dropping. When it is necessary to adjust the gap between the screen bars 27 to adjust the different types of stone material classification, the first motor 21 is started to drive the worm gear 22 to rotate, which in turn drives the worm wheel 23 and the lead screw 24 to rotate, and then drives the threaded block 261 to move left and right. This causes the sliding frame 262 to move, which in turn drives the hinge bar 263 to rotate, and drives the sliding column 264 to slide inside the screen bars 27. When the hinge bar 263 rotates, it uses the sliding column 264 to adjust the gap distance inside the screen bars 27, thereby adjusting the gap size between the screen bars 27. When the stone material is classified and discharged, different sizes and types of stone can be classified. In addition, when classifying stones, if the angle of the feeding box 32 needs to be adjusted, the fourth motor 41 is started and the threaded rod 42 is rotated, thereby causing the rectangular block 43 to move up and down on the surface of the threaded rod 42. When the rectangular block 43 moves up and down, it causes the short bars 44 on both sides to move under the limiting action inside the connecting bar 45, thereby causing the connecting bar 45 to rise or fall, and causing the feeding box 32 to rise or fall. This allows for different rates of material dropping and classification based on the amount of stone, thus improving the efficiency of material dropping and classification while also ensuring rapid material dropping.
