Description

Technical Field

[0001] This utility model relates to the field of mining, and in particular to an automatic sampling device for mining. Background Technology

[0002] Mining refers to the process of extracting valuable minerals and resources by excavating and processing underground or surface mineral resources. Before mining, samples of the mine need to be tested to roughly determine the mineral content inside.

[0003] When mining, large pieces of ore are collected, making it extremely inconvenient to test them. They need to be processed before testing can be done, resulting in low work efficiency. In addition, the sampling process is mostly done manually using drilling rigs, which is extremely labor-intensive. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic sampling device for mining, which improves the convenience of subsequent testing and makes the device easier and more convenient to use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic sampling device for mining operations, comprising:

[0007] A collection and moving box for mobile support has a collection frame opening on the upper left side. A rotating support shaft is rotatably connected inside the collection and moving box, and a crushing roller is fixedly connected to the outside of the rotating support shaft. A crushing motor is fixedly connected to the left front end of the collection and moving box, and the drive end of the crushing motor is fixedly connected to the front end of the rotating support shaft. A mixing tank is opened inside the collection and moving box, and a mixing and stirring mechanism is installed inside the mixing tank to achieve mixing of crushed powder. A fixed frame is fixedly connected to the top of the collection and moving box, and a traction block is slidably connected inside the fixed frame. A soil-crushing motor is fixedly connected inside the traction block, and a soil-breaking drill bit is fixedly connected to the drive end of the soil-crushing motor.

[0008] An electric slide rail for driving the traction block is provided. A laser displacement sensor is fixedly connected inside the right slot of the collection and moving box. The laser displacement sensor is electrically connected to the electric slide rail and the soil-crushing motor. A support assembly is installed inside the right slot of the collection and moving box.

[0009] Furthermore, the support assembly includes a rotating flip frame located on the right side of the collection and moving box. A downward sliding plate is slidably connected inside the flip frame. A stabilizing plate is rotatably connected to the lower side of the downward sliding plate. Multiple soil-breaking iron cones are uniformly fixedly connected to the inner side of the stabilizing plate. The downward sliding plate is connected to the flip frame by a positioning bolt to achieve positioning support for the downward sliding plate.

[0010] Furthermore, the positioning bolt includes a limiting rod located at the top of the lower plate, and a fixing nut is threaded onto the outer front side of the limiting rod.

[0011] Furthermore, the mixing and stirring mechanism includes a rotating rod rotatably connected inside the mixing tank, and multiple mixing scrapers are uniformly fixedly connected around the outer circumference of the rotating rod. A mixing motor is fixedly connected to the middle of the front end of the collecting and moving box, and the drive end of the mixing motor is fixedly connected to the front end of the rotating rod.

[0012] Furthermore, crushing plates are fixedly connected to both sides of the inside of the collection frame opening, and the inner groove of the crushing plate is adapted to the outer spiral of the crushing roller.

[0013] Furthermore, limit grooves are provided on both sides of the flip frame, and the external of the limiting rod is slidably connected to the inside of the limit groove.

[0014] Furthermore, multiple magnetic placement slots are evenly provided on the lower side of the right side opening of the collection and moving box, and the exterior of the soil-breaking iron cone is magnetically attracted to the interior of the magnetic placement slot.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, crushed stone falls into the inside of the collection moving box through the collection frame opening, is crushed by the crushing roller, and enters the inside of the mixing tank. The powder is evenly mixed by the cooperation of the mixing scraper and the inclined surface inside the mixing tank. The device crushes the crushed stone into powder, which improves the convenience of subsequent testing. Moreover, the powder mixing makes the proportion of ore more accurate, and the mineral content of the area can be roughly determined.

[0017] 2. In this utility model, the outer handle of the stabilizing plate unfolds the flipping frame. After the flipping frame detaches, the laser displacement sensor sends a signal to the electric slide rail and the soil-breaking motor, thereby carrying out the mining work. The lower plate and the flipping frame support the collection and moving box. The device can carry out mining work stably, reduce the consumption of manpower, and make it easier and more convenient to use. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 4 and Figure 7 This utility model provides an embodiment of an automatic sampling device for mining, comprising: a collection and moving box 1 for movable support; a collection frame opening 2 on the upper left side of the collection and moving box 1; a rotating support shaft 15 rotatably connected inside the collection and moving box 1; a crushing roller 4 fixedly connected to the outside of the rotating support shaft 15; a crushing motor 6 fixedly connected to the left front end of the collection and moving box 1; and the drive end of the crushing motor 6 fixedly connected to the front end of the rotating support shaft 15. (Refer to...) Figure 8 The collection and moving box 1 has a mixing tank 19 inside, and a mixing and stirring mechanism is installed inside the mixing tank 19 to achieve mixing between the powders. A fixed frame 3 is fixedly connected to the top of the collection and moving box 1. A traction block 8 is slidably connected inside the fixed frame 3. A soil crushing motor 12 is fixedly connected inside the traction block 8. A soil breaking drill bit 20 is fixedly connected to the drive end of the soil crushing motor 12. The mixing and stirring mechanism includes a rotating rod 17 rotatably connected inside the mixing tank 19. Multiple mixing scrapers 16 are evenly fixedly connected around the outside of the rotating rod 17. A mixing motor 7 is fixedly connected to the middle of the front end of the collection and moving box 1. The drive end of the mixing motor 7 is fixedly connected to the front end of the rotating rod 17. Crushing plates 5 are fixedly connected to both sides inside the collection frame opening 2. The inner groove of the crushing plate 5 is adapted to the outer spiral of the crushing roller 4.

[0031] The crushed lumps fall into the collection box 1 through the collection frame opening 2. At the same time, the crushing motor 6 and the mixing motor 7 are started. The crushing motor 6 rotates the rotating support shaft 15, and the crushing roller 4 rotates. The outer spiral of the crushing roller 4 contacts the protrusion of the crushing plate 5, thereby crushing the lumps. The powder falls into the mixing tank 19 through the inclined surface inside the collection box 1. The mixing motor 7 drives the rotating rod 17 to rotate, thereby rotating the mixing scraper 16. The two inclined surfaces of the mixing tank 19 move closer to the center. When the mixing scraper 16 rotates, it stirs and disperses the powder. This process is repeated to mix the powder evenly. Finally, the powder is sampled through the discharge pipe at the bottom. The device crushes the gravel into powder, which improves the convenience of subsequent testing. Moreover, the powder mixing makes the proportion of ore more accurate, which can roughly determine the mineral content of the area.

[0032] Reference Figure 2 , Figure 3 and Figure 4 An electric slide rail 21 is used to drive the traction block 8. A laser displacement sensor 13 is fixedly connected inside the right slot of the collecting and moving box 1. The laser displacement sensor 13 is electrically connected to the electric slide rail 21 and the soil-crushing motor 12. A support assembly is installed inside the right slot of the collecting and moving box 1. (Refer to...) Figure 5 and Figure 6The support assembly includes a rotating flip frame 9 located on the right side of the collection and moving box 1. A lowering plate 10 is slidably connected inside the flip frame 9. A stabilizing plate 11 is rotatably connected to the lower side of the lowering plate 10. Multiple soil-breaking cones 18 are evenly fixedly connected to the inner side of the stabilizing plate 11. The lowering plate 10 is connected to the flip frame 9 via a positioning bolt for positioning and support. The positioning bolt includes a limiting rod 22 located at the top of the lowering plate 10. A fixing nut 23 is threaded onto the outer front side of the limiting rod 22. (Refer to...) Figure 9 Both sides of the flip frame 9 are provided with limiting grooves 24. The outside of the limiting rod 22 is slidably connected to the inside of the limiting groove 24. Multiple magnetic placement slots 14 are evenly provided on the lower side of the right slot of the collection and moving box 1. The outside of the soil breaking iron cone 18 is magnetically attached to the inside of the magnetic placement slot 14 respectively.

[0033] During sampling, the device is moved to the wall to be mined by the drive wheels at the bottom of the collection and moving box 1. At this time, the handle on the outside of the stabilizing plate 11 is pushed outward, thereby unfolding the flipping frame 9 outward. Then, the lowering plate 10 is pulled downward. When the stabilizing plate 11 contacts the ground, the stabilizing plate 11 is flipped, and the soil-breaking iron cone 18 is moved to the ground. Multiple soil-breaking iron cones 18 are inserted into the ground for support, and the fixing nut 23 is rotated to press against the outside of the flipping frame 9. When the flipping frame 9 unfolds, the laser displacement sensor 13 detects the displacement of the flipping frame 9, and at the same time, the soil-breaking motor 12 and the electric slide rail 21 are started. As the electric slide rail 21 feeds, the traction block 8 moves, and the soil-breaking drill bit 20 contacts the wall to crush. When the flipping frame 9 closes, the laser displacement sensor 13 sends a return signal to the electric slide rail 21 and turns off the soil-breaking motor 12. The device can carry out mining work stably, reduce manpower consumption, and make it easier and more convenient to use.

[0034] Working principle: During sampling, the device is moved to the wall to be mined by the drive wheels at the bottom of the collection and moving box 1. At this time, the handle on the outside of the stabilizing plate 11 is pushed outward, thereby unfolding the flipping frame 9 outward. Then, the lowering plate 10 is pulled downward. When the stabilizing plate 11 contacts the ground, it is flipped, moving the soil-breaking cone 18 to the ground. Multiple soil-breaking cones 18 are inserted into the ground for support, and the fixing nut 23 is rotated to press against the outside of the flipping frame 9. When the flipping frame 9 unfolds, the laser displacement sensor 13 detects the displacement of the flipping frame 9, and at the same time, the soil-breaking motor 12 and the electric slide rail 21 are started. As the electric slide rail 21 feeds, the traction block 8 moves, breaking the soil. The drill bit 20 contacts the wall to crush the material. The crushed material falls into the collection box 1 through the collection frame opening 2. At the same time, the crushing motor 6 and the mixing motor 7 are started. The crushing motor 6 rotates the rotating support shaft 15 and the crushing roller 4. The outer spiral of the crushing roller 4 contacts the protrusion of the crushing plate 5, thereby crushing the material. The crushed powder falls into the mixing tank 19 through the inclined surface inside the collection box 1. The mixing motor 7 drives the rotating rod 17 to rotate, thereby rotating the mixing scraper 16. The two inclined sides of the mixing tank 19 move closer to the center. When the mixing scraper 16 rotates, it stirs and disperses the crushed powder. This process is repeated to mix the crushed powder evenly. Finally, the powder is sampled through the discharge pipe at the bottom.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
