Description

Technical Field

[0001] The invention belongs to the technical field of mining equipment, and in particular relates to a green and safe crushing device for mining. Background Art

[0002] With the continuous advancement of industrialization, the mining of mineral resources has become an important pillar of economic development. In the process of mining resources, in order to be more energy-saving and environmentally friendly and reduce the impact of mining mineral resources on the environment, green and safe crushing devices will be used. Green and safe crushing devices are generally reflected in energy saving, environmental protection, low noise, dust control and other aspects.

[0003] However, it is difficult for the green and safe crushing device to crush large pieces of ore during use. When facing large pieces of stone, it is necessary to pre-crush the large pieces of ore and crush them into small pieces of ore that can be crushed by the green and safe crushing device. During pre-crushing, crushing tools are generally used manually to divide large ores into small pieces, and then the small pieces of ore are sent to the conveyor belt by manpower or tools, and the conveyor belt transports the small pieces of ore to the green and safe crushing device for crushing. There are certain safety hazards in crushing by using crushing tools manually, and the efficiency of transporting small pieces of ore by manpower or tools is low. Especially for some soft ores, such as talc, plaster, gypsum and calcite, a large amount of dust will be generated during the manual crushing process. These dusts are exposed to the air and have a certain impact on the environment. If the crushing workers inhale this dust, it will also cause certain harm to the workers' bodies, which is not conducive to green and safe mining.

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] like Figure 1 to Figure 3As shown, a green and safe crushing device for mining in one embodiment of the present invention includes a first crushing mechanism 1, a second crushing mechanism 7 and a fourth crushing mechanism 25. Large pieces of ore are placed in the first crushing mechanism 1 to wait for crushing, and the first crushing mechanism 1 can pre-crush the large pieces of ore. The second crushing mechanism 7 is arranged above the first crushing mechanism 1, and the second crushing mechanism 7 crushes the large pieces of ore by hitting downward from the upper end. The fourth crushing mechanism 25 is installed at the lower end of the first crushing mechanism 1, and the fourth crushing mechanism 25 can continue to crush the ore crushed by the second crushing mechanism 7 and the first crushing mechanism 1, and crush the ore into a size that meets the requirements.

[0035] like Figure 1 to Figure 3 As shown, the first crushing mechanism 1 includes a first shell 2, the upper end of the first shell 2 has a large outer diameter and the lower end has a small outer diameter, and large pieces of ore can be placed in the first shell 2. A first guide plate 3 is arranged on one side of the first shell 2, and the first guide plate 3 is arranged obliquely. The first guide plate 3 serves as a slideway for the movement of large pieces of ore. When the large pieces of ore slide from the first guide plate 3 to the first shell 2, the speed will gradually increase. A plurality of evenly distributed first crushing teeth 4 are fixedly connected to the side of the first shell 2 opposite to the first guide plate 3. When the large pieces of ore slide from the first guide plate 3 to the first shell 2, the large pieces of ore contact the first crushing teeth 4, and the impact force generated by the large pieces of ore contact the first crushing teeth 4 to achieve pre-crushing of the large pieces of ore. That is, the large pieces of ore are pre-crushed by using their own weight and the force generated by movement to contact the first crushing teeth 4. Some soft large pieces of ore can even be directly crushed by the first crushing teeth 4.

[0036] like Figure 1 to Figure 3 As shown, a partition bar 5 is installed at the lower part of the first shell 2, and the partition bar 5 plays the role of filtering ore. After the large pieces of ore are crushed, they can enter the fourth crushing mechanism 25 through the partition bar 5. Among them, the size of the ore that can pass through the partition bar 5 meets the specification requirements of the fourth crushing mechanism 25 for crushing the ore. Crushing by the fourth crushing mechanism 25 saves the cost of manually crushing and transporting large pieces of ore, which is conducive to improving the efficiency of ore crushing. A plurality of second crushing teeth 6 are fixedly connected to the upper end of the partition bar 5, and the second crushing teeth 6 can cooperate with the second crushing mechanism 7 to assist in crushing large pieces of ore.

[0037] like Figures 1 to 10As shown, the second crushing mechanism 7 is lifted by the hoisting mechanism 50, and the hoisting mechanism 50 can lift the second crushing mechanism 7 to the upper part of the large ore. When the second crushing mechanism 7 is needed to crush the large ore, the hoisting mechanism 50 removes the lifting force on the second crushing mechanism 7, so that the second crushing mechanism 7 can move downward quickly by its own gravity, thereby hitting the upper end of the large ore, and the large ore is crushed by hitting. This method is more conducive to crushing some soft stones, and has a simple structure, easy operation, and is not easy to generate dust, which is conducive to green and safe mining of mines.

[0038] like Figure 9-10 As shown, the second crushing mechanism 7 includes a counterweight body 8, and a plurality of third crushing teeth 9 are fixedly connected to the lower part of the counterweight body 8. The third crushing teeth 9 can increase the impact force when the counterweight body 8 contacts the large ore, thereby improving the crushing capacity of the counterweight body 8. The upper end of the counterweight body 8 is also fixedly connected to a first bracket 10, and an impact structure 11 is installed inside the first bracket 10. A mounting plate 13 is installed between the impact structure 11 and the first bracket 10, and one end of the mounting plate 13 is fixedly connected to the impact structure 11, and the other end is slidably connected to the first bracket 10. A first oil cylinder 14 is also fixedly connected between the first bracket 10 and the counterweight body 8, and the position of the impact structure 11 can be adjusted up and down by the first oil cylinder 14. A drill rod 12 is also installed on the output shaft of the impact structure 11, and a first through hole 801 matching the drill rod 12 is opened on the counterweight body 8. Through the cooperation of the impact structure 11 and the drill rod 12, a hole is drilled in the large ore by applying an impact force to the large ore. Due to the crushing effect of the impact force, the large ore is loose and gradually broken. In particular, it is easier to crush some large ores with loose structures and soft qualities. The large ores are directly crushed on the crushing device, which reduces the number of manual crushing of large ores and helps to improve the efficiency of crushing large ores.

[0039] like Figure 9-10 As shown, the first oil cylinder 14 can change the position of the impact structure 11, that is, the first oil cylinder 14 can change the position of the drill rod 12, and the first oil cylinder 14 can continuously provide the impact structure 11 with a force toward the side of the bulk ore, which is more conducive to the impact structure 11 and the drill rod 12 to cooperate to complete the crushing of the bulk ore. The first bracket 10 can also apply a certain force to the second crushing mechanism 7. When the second crushing mechanism 7 is located on the upper part of the bulk ore, the force generated by the first bracket 10 acts on the counterweight 8, so that the counterweight 8 can also vibrate in the bulk ore. During the vibration, the third crushing tooth 9 further contacts the bulk ore, that is, during the operation of the impact structure 11, the counterweight 8 can be used to vibrate, which is conducive to the continuous crushing of the bulk ore.

[0040] Preferably, Figure 9-10As shown, the counterweight 8 is provided with a pressure detection mechanism (not shown in the figure) matching with the third crushing tooth 9. The pressure detection mechanism hits the large ore. If the large ore is broken, the pressure detection mechanism will detect the critical point of breaking. Its principle is similar to that of a pressure tester. It is judged whether the large ore has been broken by this critical point. If the large ore is not broken, the impact structure 11 and the drill rod 12 are started to further break the large ore, or the second crushing mechanism 7 is repeatedly lifted and lowered by the hoisting mechanism 50, and the large ore is broken by lifting and lowering the second crushing mechanism 7 by the hoisting mechanism 50.

[0041] like Figure 1 to Figure 4 As shown, the fourth crushing mechanism 25 includes a second shell 26, and the second shell 26 is installed at the lower end of the first shell 2. Two toothed rollers 27 are rotatably connected inside the second shell 26, and the two toothed rollers 27 crush the ore crushed by the second crushing mechanism 7 into a required size. A belt pulley 30 is fixedly connected to one side of the toothed roller 27, and a motor 31 is installed on the first shell 2. A belt 32 is installed between the belt pulley 30 and the motor 31. The belt 32 is driven to rotate by the motor 31, and the belt 32 drives the belt pulley 30 to rotate, thereby realizing the high-speed rotation of the toothed roller 27 inside the second shell 26, and the crushing of small pieces of ore is completed during the high-speed rotation.

[0042] In order to extend the service life of the toothed roller 27 and reduce the thermal decay of the toothed roller 27 caused by excessive heat generated during the crushing process of the toothed roller 27, and reduce the impact on the crushing efficiency, a first cavity 28 is provided in the toothed roller 27, and the first cavity 28 is used to fill water. The heat generated during the crushing process of the toothed roller 27 is exchanged with the first cavity 28, which can reduce the heat of the toothed roller 27, facilitate cooling the toothed roller 27, and reduce the impact on the crushing efficiency of the toothed roller 27 caused by excessive heat.

[0043] Since a large amount of dust is generated when small pieces of ore are crushed into ore that meets the requirements, it is not conducive to green and safe mining. In order to solve the above problems, a drainage hole 2701 is provided on the toothed roller 27, and the drainage hole 2701 is connected to the counterweight body 8. A valve 29 matching the drainage hole 2701 is installed on the toothed roller 27, and the valve 29 can control whether the water in the first cavity 28 is sprayed outward. During the high-speed rotation of the toothed roller 27, a strong centrifugal force is generated, and the water in the first cavity 28 is sprayed out from the drainage hole 2701 by the centrifugal force. The valve 29 can specifically be a spray valve, which can spray the water in the drainage hole 2701 in the form of water mist and can control the on and off of the drainage hole 2701. The high-speed sprayed water mist contacts the dust generated by the crushing, which can achieve a dust reduction effect. At the same time, by changing the amount of water sprayed, for some ores with more impurities such as mud on the surface, by pressurizing the first cavity 28 to make the tooth roller 27 spray a large amount of water, the impurities on the surface of the ore can be flushed, thereby completing the cleaning pretreatment of the ore.

[0044] like Figure 1 to Figure 5 As shown, a discharge port 2601 is provided at the lower end of the second shell 26, a third shell 39 is installed at the lower end of the second shell 26, and a filter mechanism 33 matching the discharge port 2601 is installed in the third shell 39. The filter mechanism 33 is arranged obliquely, and the filter mechanism 33 can separate ore and water, and can also separate large ore and some fine ore, which is conducive to improving the quality of the ore.

[0045] like Fig.11 As shown, the filtering mechanism 33 includes a second guide plate 34, and a plurality of evenly distributed first filter holes 3401 are provided on the second guide plate 34, which can separate the ore from water and mud, and some ores with an outer diameter smaller than the first filter holes 3401 are also filtered, which is beneficial to improving the quality of the ore. The second guide plate 34 is also fixedly connected with a plurality of slow-flow bars 35 matching the first filter holes 3401, and the slow-flow bars 35 can make the ore jump on the surface of the slow-flow bars 35, and in the process of jumping, the moisture on the surface of the ore is drained as much as possible, reducing the moisture on the surface of the ore, and can also shake off some ore debris.

[0046] like Figure 1 to Figure 5As shown, a first conveying mechanism 36 matching the filtering mechanism 33 is installed in the third housing 39. The first conveying mechanism 36 is also tilted, and the first conveying mechanism 36 and the filtering mechanism 33 are V-shaped. After the ore passes through the filtering mechanism 33, it falls on the first conveying mechanism 36. Since the first conveying mechanism 36 is also tilted, the ore can also be drained during the transportation process. The first conveying mechanism 36 is located inside the third housing 39, and the drained water is temporarily stored in the third housing 39, and the water stains are not easy to flow to the outside of the crushing device. A second conveying mechanism 38 matching the first conveying mechanism 36 is installed on one side of the third housing 39. The ore on the first conveying mechanism 36 is transported to the second conveying mechanism 38, and the second conveying mechanism 38 discharges the ore to the crushing device.

[0047] like Figure 4-5 As shown, the first conveying mechanism 36 is internally connected to a plurality of elliptical rollers 37 for rotation, and the outer surface of the elliptical rollers 37 is in contact with the belt portion of the first conveying mechanism 36. The first conveying mechanism 36 will rotate with the elliptical rollers 37 during the rotation process, and the elliptical rollers 37 will vibrate the belt portion of the first conveying mechanism 36. When the belt portion of the first conveying mechanism 36 vibrates, the drainage effect of the ore can be further improved. The belt portion of the first conveying mechanism 36 is provided with a second filter hole 3601. During the vibration of the belt portion, the drained water can directly fall from the second filter hole 3601, which is conducive to improving the drainage effect of the ore.

[0048] like Figure 1 to Figure 5 As shown, the water in the first cavity 28 is provided by a water supply mechanism 40, which includes a water tank 41. A water supply pipe 42 is installed on one side of the water tank 41. Liquid can be added to the water tank 41 through the water supply pipe 42. A first water delivery pipe 44 is installed on the end of the water tank 41 and the gear roller 27 away from the belt pulley 30. A rotary joint 49 is installed between the first water delivery pipe 44 and the gear roller 27. Water is delivered to the first cavity 28 through the rotary joint 49, and the gear roller 27 will not affect the first water delivery pipe 44 during the rotation process. A return water pipe 43 is installed between the water tank 41 and the third shell 39, and a filter (not shown in the figure) is installed on the end of the return water pipe 43 away from the water tank 41. The return water pipe 43 can deliver water back to the water tank 41, and filter out impurities in the water in the third shell 39 through the filter, so that the water cycle can be completed, energy saving and environmental protection, and green mining are beneficial.

[0049] In order to further reduce the dust generated by the crushing device when crushing large pieces of ore, such as Figures 1 to 10As shown, a dust-proof mechanism 46 is installed on the second crushing mechanism 7, and the dust-proof mechanism 46 sprays water mist toward the entrance of the first shell 2. When the second crushing mechanism 7 is at a high position, the water mist sprayed by the dust-proof mechanism 46 can cover the entrance of the first shell 2, reduce the dust flying out of the first shell 2, and reduce the impact of the dust on the environment.

[0050] Specifically, the dust prevention mechanism 46 includes a third water pipe 47, which is fixedly connected to the outer wall of the counterweight body 8, and a plurality of evenly distributed nozzles 48 are installed on the third water pipe 47, and the nozzles 48 and the third water pipe 47 are connected, and the liquid in the third water pipe 47 can be sprayed out in the form of water mist through the nozzles 48. The water mist completely covers the inlet of the first shell 2 to prevent dust from flying out from the inlet of the first shell 2.

[0051] Preferably, the dust-proof mechanism 46 is installed at the upper end of the second crushing mechanism 7, and does not move with the up and down movement of the second crushing mechanism 7. The dust-proof mechanism 46 is fixed above the first shell 2 through a connecting mechanism (not shown in the figure), and a protective shell (not shown in the figure) is used to protect the impact structure 11 to prevent the sprayed water mist from damaging the impact structure 11. With this arrangement, no matter what state the second crushing mechanism 7 is in, the dust-proof mechanism 46 can spray water mist at the entrance of the first shell 2, which is more conducive to dust reduction.

[0052] Preferably, a sewage discharge mechanism (not shown in the figure) is also provided on the side wall of the third shell 39. When there are too many impurities in the third shell 39, the impurities in the third shell 39 can be discharged through the sewage discharge mechanism.

[0053] By setting the first shell 2, large pieces of ore can be placed on the first shell 2. The first guide plate 3 and the first crushing teeth 4 matched with the first guide plate 3 provided on one side of the first shell 2 can impact the large pieces of ore when entering the first shell 2 through the force generated by the large pieces of ore, thereby realizing the pre-crushing of the large pieces of ore. By setting the second crushing mechanism 7 at the upper end of the first shell 2, the large pieces of ore can be crushed by the downward impact of the second crushing mechanism 7. The bottom of the first shell 2 is equipped with a partition bar 5 and a second crushing tooth 6. The second crushing mechanism 7, the partition bar 5 and the second crushing tooth 6 cooperate to improve the efficiency of crushing large pieces of ore. For large pieces of ore that are difficult to crush, the large pieces of ore can also be impacted by the cooperation of the impact structure 11 and the drill rod 12 to realize the crushing of the large pieces of ore. The first oil cylinder 14 can provide a downward pressure force to the impact structure 11, which is conducive to the cooperation of the impact structure 11 and the drill rod 12 to crush the large pieces of ore. There is no need to manually crush large pieces of ore and throw them into the crushing device. Large pieces of ore can be crushed by the crushing device itself, which saves manpower and avoids the dangers of manual crushing of ore, which is conducive to safe mining of ore.

[0054] By setting up the fourth crushing mechanism 25, the large pieces of ore after crushing can be crushed for the second time, and the ore can be crushed into ores of qualified size by the second crushing, and the water source is provided by the toothed roller 27 through the water supply mechanism 40, so that the toothed roller 27 can spray water mist or water outward to reduce the dust generated by the fourth crushing mechanism 25 during the crushing process, which is conducive to the green and safe crushing of ore. The water used for dust reduction can also be used to clean the ore. Through the cooperation of the filtering mechanism 33, the first conveying mechanism 36 and the second conveying mechanism 38, the separation of water, ore and impurities can be achieved, and the water supply mechanism 40 can circulate the water used for cleaning and dust reduction, which is energy-saving and environmentally friendly, and is conducive to green mining of ore.

[0055] In order to make the green and safe crushing device better able to crush large pieces of ore, improve the crushing performance of the green and safe crushing device so that it can crush harder ores. Figures 1 to 8 As shown, a plurality of groups of third crushing mechanisms 15 are installed on the side wall of the first shell 2. The plurality of groups of third crushing mechanisms 15 can drill holes in large pieces of ore by hammer drilling and destroy the internal structure of the large pieces of ore, which is beneficial to the crushing of the large pieces of ore.

[0056] Specifically, Figures 1 to 8 As shown, a sleeve 201 is fixedly connected to the outer wall of the first shell 2, and the third crushing mechanism 15 includes a crushing nail 16 matching the sleeve 201, and the crushing nail 16 is slidably connected inside the sleeve 201. A second bracket 18 is fixedly connected to the side of the crushing nail 16 away from the first shell 2, and a second oil cylinder 17 is installed on the second bracket 18, and the crushing nail 16 can be driven to move in the sleeve 201 through the second oil cylinder 17. A third bracket 20 is installed at the lower end of the second bracket 18, and an accumulator 19 matching the second oil cylinder 17 is installed in the third bracket 20. The accumulator 19 can greatly increase the instantaneous pressure provided by the second oil cylinder 17 to the crushing nail 16, and this pressure can make the crushing nail 16 drill into large pieces of ore to destroy the structure of the ore.

[0057] like Figures 1 to 8 As shown, a first chute 2011 is provided on the sleeve 201, a first slider 1601 matching the first chute 2011 is fixedly connected to the crushing nail 16, a spring is installed between the first slider 1601 and the side wall of the first chute 2011, and one end of the spring is welded to the side wall of the first chute 2011, and the other end is welded to the side wall of the first slider 1601. The spring can reset the crushing nail 16 after impacting the ore once.

[0058] like Figure 1 to Figure 6As shown, a groove 1603 is provided on the crushing nail 16, and a crushing detection mechanism 21 matching the groove 1603 is installed on the crushing nail 16. The crushing detection mechanism 21 can detect whether the ore is broken. And realize the linkage with the second oil cylinder 17 and the second bracket 18. If it is detected that the ore is not broken, the second oil cylinder 17 is retracted, and the second oil cylinder 17 is charged through the second bracket 18, so that the second oil cylinder 17 hits the crushing nail 16 again, so that the crushing nail 16 drills a hole in the ore. Among them, the crushing detection mechanism 21 includes a detection rod 22, the detection rod 22 matches the groove 1603, and is rotatably connected in the groove 1603. The other end of the detection rod 22 is fixedly connected to the bottom wall of the groove 1603 with an elastic mechanism 23. The elastic mechanism 23 can change the size of the angle formed between the detection rod 22 and the crushing nail 16. When the detection rod 22 is subjected to pressure, the elastic mechanism 23 will shrink. The bottom wall of the groove 1603 is fixedly connected with a pressure sensor 24 matching the elastic mechanism 23. The pressure sensor 24 can detect whether the elastic mechanism 23 is subjected to pressure, and the pressure can be used to determine whether the ore is broken.

[0059] like Figure 6 As shown, the sleeve 201 is provided with a second slide groove 2012 matching the detection rod 22, and the second slide groove 2012 can keep the detection rod 22 in the initial detection state when in the sleeve 201. A second slider 1602 matching the second slide groove 2012 is fixedly connected to the crushing nail 16, and the crushing nail 16 can be stably slidably connected in the sleeve 201 through the cooperation of the second slider 1602 and the first slider 1601, and the crushing nail 16 will not rotate.

[0060] Since the elastic mechanism 23 still has a certain elasticity after the detection rod 22 is moved to a certain angle, the elastic mechanism 23 enters the drill hole and contacts the inner wall of the drill hole. During the retreat process, it will generate friction with the inner wall of the drill hole and get stuck. When the second oil cylinder 17 hits the breaking nail 16 again, the movement stroke of the breaking nail 16 can be reduced to provide stronger penetration force.

[0061] Preferably, one end surface of the detection rod 22 close to the second bracket 18 is tooth-shaped.

[0062] The working principle of the crushing device is as follows: the large ore slides into the first shell 2 through the first guide plate 3, and one side of the ore contacts the first crushing tooth 4, which penetrates into the interior of the large ore and can destroy the structure of the large ore. Then the second crushing mechanism 7 descends from above, and the impact force generated is used to hit the large ore. The pressure detection mechanism determines whether the large ore is broken. If not, the second crushing mechanism 7 descends from above and hits the ore repeatedly until the large ore is broken. After the large ore is broken, the medium ore is obtained. The medium ore enters the second shell 26 through the dividing bar 5 and contacts the tooth roller 27. The two tooth rollers 27 crush the medium ore to obtain qualified ore that meets the requirements.

[0063] During the crushing process of the fourth crushing mechanism 25, the water supply mechanism 40 provides water to the fourth crushing mechanism 25. The water is located in the first cavity 28 and can exchange heat with the tooth roller 27 to reduce the temperature generated by the tooth roller 27 when crushing the ore. The water in the first cavity 28 is sprayed out through the drainage hole 2701 to reduce the dust generated during the crushing process. The water can contact the outer surface of the tooth roller 27 to cool the outer surface of the tooth roller 27, thereby avoiding thermal attenuation caused by long-term operation of the tooth roller 27 and affecting the crushing efficiency of the ore.

[0064] The ore that meets the requirements continues to fall onto the filtering mechanism 33, which can separate the ore that meets the requirements from water and other impurities. The ore that meets the requirements slides along the direction set by the filtering mechanism 33, and the ore and water are separated. The ore falls on the surface of the first conveying mechanism 36, and a secondary drainage operation is performed through the first conveying mechanism 36, and finally the ore is conveyed out of the crushing device through the second conveying mechanism 38.

[0065] like Fig.12 As shown, during the operation of the crushing device, the dust-proof mechanism 46 above the first shell 2 continuously sprays water mist, and a second water pipe 45 is installed between the dust-proof mechanism 46 and the water tank 41. The water source in the water tank 41 can be transported to the dust-proof mechanism 46 through the second water pipe 45, and cover the top of the first shell 2 to prevent the dust generated by the crushed stones from affecting the environment.

[0066] The working principle of the third crushing mechanism 15 is as follows: when a large piece of hard ore needs to be crushed, after the ore is located in the first housing 2, the second oil cylinder 17 is started, and the second oil cylinder 17 pushes the crushing nail 16 to move in the direction of the large piece of ore, and makes the crushing nail 16 drill into the large piece of ore. If the crushing detection mechanism 21 does not detect a change, the second oil cylinder 17 cooperates with the second bracket 18 to continue drilling the ore. If the crushing detection mechanism 21 detects a change, but the data detected by the crushing detection mechanism 21 does not return to the initial value, it is judged that the crushing nail 16 has drilled into the large piece of ore, but the large piece of ore has not been crushed. The second oil cylinder 17 and the second bracket 18 cooperate to continue hammering the crushing nail 16 three to six times. If the data of the crushing detection mechanism 21 has not returned to the initial value, the crushing detection mechanism 21 is fully extended into the groove 1603, and the crushing nail 16 has the cooperation of the spring and can return to its position by itself. Since the structure of the large ore has been destroyed by the third crushing mechanisms 15, the large ore can be smashed downward by the second crushing mechanism 7, so that the ore can be crushed more easily, which is beneficial for crushing hard ore.
