Description

Technical Field

[0001] The invention relates to the field of mine quarrying equipment, in particular to a mine quarrying machine capable of cutting mine raw stones. Background Art

[0002] With the continuous development of mining, traditional mining quarries have played an important role in the cutting of raw stones in mines. However, there are some obvious deficiencies in the quarrying equipment in the existing technology. Most traditional mining quarries use fixed angle cutting, which limits their cutting flexibility and accuracy when processing raw stones of different shapes and specifications. This limitation not only affects the processing quality of the raw stones, but also reduces their utilization rate, resulting in considerable material waste. In addition, a large amount of dust is generated during the cutting process, which not only threatens the health of workers, but also has a negative impact on the air quality and ecological environment around the mining area. Although some equipment is equipped with dust removal systems, these systems are usually bulky and costly, which brings additional burdens to mine operations.

[0003] Therefore, those skilled in the art have proposed a mining quarrying machine capable of cutting raw stones in a mine to solve the above problems. Summary of the invention

[0014] Preferably, one end of each of the four first connecting rods is rotatably connected to the outer side of the fixed plate, and a rubber pad is provided on the inner side of the second connecting rod.

[0015] Preferably, the dust reduction assembly includes a water tank and a support plate, the water tank is fixedly connected to the outer side of the first swing arm, the support plate is fixedly connected to the outer side of the connecting frame, the inner side of the support plate is fixedly connected to a fixed cylinder, the interior of the fixed cylinder is slidably connected to a rubber piston, the outer side of the rubber piston is fixedly connected to a movable column, the outer side of the fixed cylinder is connected to a second connecting pipe, the outer side of the fixed cylinder is also connected to a first connecting pipe, and one-way valves are installed on the inner sides of the first connecting pipe and the second connecting pipe.

[0016] Preferably, one end of the first connecting pipe is fixedly connected to an atomizing nozzle, the flow directions of the two one-way valves are opposite, and one end of the second connecting pipe is connected to the outside of the water tank.

[0017] Preferably, the driving assembly includes a spring, a contact plate and an eccentric wheel, the spring is sleeved on the outside of the movable column, the contact plate is fixedly connected to the bottom end of the movable column, the eccentric wheel is fixedly connected to the other output end of the dual-axis servo motor, and the outer surface of the eccentric wheel is connected to the outer side of the contact plate.

[0018] Preferably, the top end of the spring is fixedly connected to the outer side of the support plate, and the bottom end of the spring is fixedly connected to the top of the contact plate.

[0019] Preferably, a control box is installed on the outside of the placement box, and the control box is electrically connected to the dual-axis servo motor, the first hydraulic cylinder, and the second hydraulic cylinder respectively.

[0020] Working principle: To use this device, firstly, the dual-axis servo motor is started to drive the cutting saw blade to rotate, and the raw stone in the mine is cut by the cutting saw blade. The multi-angle cutting component is rotated by the first electric turntable. In addition, the second hydraulic cylinder is started to drive one side of the second swing arm to swing, so that the angle between the second swing arm and the first swing arm becomes larger or smaller. The connecting frame is swung by starting the electric telescopic rod, so that the cutting saw blade can rotate at multiple angles, and the raw stone in the mine can be cut at multiple angles. This can significantly improve the flexibility and accuracy of cutting. Compared with the traditional cutting method which is often limited to a single angle, the utilization rate of the raw stone can be reduced, and the full utilization of the raw stone can be achieved.

[0021] After the rough stone is cut, the second electric turntable is used to rotate the connecting frame 90 degrees. At this time, the grabbing assembly works, and the support seat is moved by starting the first hydraulic cylinder, so that one end of the multiple second connecting rods swings, and the second connecting rods open outward under the traction of the first connecting rods. When the cut rough stone contacts the inner side of the second connecting rod, the output end of the first hydraulic cylinder contracts, and the four second connecting rods contract inward to fix the rough stone. Then, the rough stone is placed on the placement box in cooperation with the multi-angle cutting assembly;

[0022] During the process of cutting the raw stone, the eccentric wheel will also be driven to rotate eccentrically with the start of the output end of the dual-axis servo motor. Since the contact plate is in contact with the eccentric wheel, the contact plate drives the movable column to reciprocate up and down under the action of the spring reset. When the movable column moves downward, it drives the rubber piston to move downward along the inner wall of the fixed cylinder, so that the interior of the fixed cylinder is in a negative pressure state. Since the water storage tank is connected to the fixed cylinder through the second connecting pipe, when the interior of the fixed cylinder is in a negative pressure state, the water inside the water storage tank can enter the interior of the fixed cylinder through the second connecting pipe. When the rubber piston moves upward, the water inside the fixed cylinder is discharged onto the outer surface of the cutting saw blade through the first connecting pipe and the atomizing nozzle. Dust reduction treatment is achieved in this way, which reduces the risk of workers inhaling harmful particles. Secondly, reducing the flying of dust can improve the air quality around the mining area.

[0023] The present invention provides a mining quarrying machine capable of cutting raw stones in a mine. The machine has the following beneficial effects:

[0024] 1. The present invention can cut the mine raw stones at multiple angles by adding a multi-angle cutting component, which can significantly improve the flexibility and accuracy of cutting. Compared with the traditional cutting method which is often limited to a single angle, the utilization rate of the raw stones can be reduced, the full utilization of the raw stones can be achieved, and material waste can be minimized.

[0025] 2. The present invention adds a grabbing component, which can automatically place the raw stones in a placement box for centralized storage after the raw stones are cut. This improves operating efficiency, reduces the time and labor cost of manual handling, and makes ore processing more efficient.

[0026] 3. The present invention can degrade the dust generated during the cutting process of raw stones in mines by adding dust reduction components, thereby reducing the risk of workers inhaling harmful particulate matter. Reducing the flying of dust can improve the air quality around the mining area and reduce the impact on the surrounding ecological environment and residents' lives. At the same time, there is no need to purchase large-scale dust removal equipment, which saves costs. The overall structural design is reasonable and easy for people to use.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0037] Please see attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides a mining quarrying machine capable of cutting raw stones in a mine, comprising:

[0038] The machine body 1 is used as a support carrier of the whole device, and a placement box 2 for loading raw stones from the mine is arranged on one side of the top of the machine body 1;

[0039] A multi-angle cutting assembly is installed on one side of the top of the machine body 1 and is used to perform multi-angle cutting on the raw stones in the mine;

[0040] The multi-angle cutting assembly includes a first electric turntable 401, which is fixedly connected to one side of the top of the machine body 1, a first swing arm 402 is installed on the top of the first electric turntable 401, a second hydraulic cylinder 403 is rotatably installed on the outer side of the first swing arm 402, a second swing arm 404 is rotatably installed on the output end of the second hydraulic cylinder 403, a second electric turntable 409 is installed on the inner side of the second swing arm 404, an electric telescopic rod 405 is rotatably installed on the outer side of the second swing arm 404, a connecting frame 407 is rotatably installed on the output end of the electric telescopic rod 405, a double-axis servo motor 408 is installed inside the connecting frame 407, and a cutting saw blade 406 is fixedly connected to one of the output ends of the double-axis servo motor 408. One end of the second swing arm 404 is rotatably connected to the outer side of the first swing arm 402, and the top end of the connecting frame 407 is rotatably connected to the end of the second swing arm 404.

[0041] Specifically, the dual-axis servo motor 408 is started: by controlling the rotation of the motor, the cutting saw blade 406 starts to rotate at high speed. The high-precision control of the dual-axis servo motor 408 can ensure the stability during the cutting process and reduce the cutting error. The first electric turntable 401 rotates: at the same time, the first electric turntable 401 can rotate in the horizontal direction, providing a basic angle adjustment for cutting. Through the rotation of the electric turntable, the cutting assembly can achieve all-round contact with the original stone, improving the cutting efficiency.

[0042] When the cutting angle needs to be changed, the second hydraulic cylinder 403 is activated to drive the second swing arm 404 to swing. This movement can increase or decrease the angle between the second swing arm 404 and the first swing arm 402, so that the cutting saw blade 406 can cut the rough stone at different angles.

[0043] When it is necessary to further adjust the cutting depth or angle, the electric telescopic rod 405 is activated. By changing the height and position of the connection frame 407, the cutting saw blade 406 can be positioned more accurately, thereby achieving cutting at different angles.

[0044] Through the cooperation of the above components, the cutting saw blade 406 can cut at various angles to adapt to rough stones of different shapes and hardness. This multi-angle cutting capability significantly improves the flexibility and accuracy of cutting, allowing operators to quickly adjust cutting strategies according to actual needs.

[0045] Through this multi-angle cutting component, operators can flexibly deal with different types of mine rough stones, ensuring efficient and accurate cutting. Compared with the traditional single-angle cutting method, it greatly improves the utilization rate of rough stones. This cutting method can:

[0046] Improve work efficiency: By flexibly adjusting the cutting angle and depth, the need for multiple cuts is reduced, saving time and resources.

[0047] Improve cutting accuracy: The multi-angle cutting capability ensures that each cutting surface meets the design requirements and reduces waste. Improve operational safety: The efficiency and accuracy of the cutting system reduce operational risks and protect the safety of operators. Strong adaptability: The system can handle various types and shapes of raw stones and is widely used in mining, stone processing and other fields.

[0048] A grabbing assembly, which is installed outside the multi-angle cutting assembly and is used to grab the cut ore and place it in the placement box 2;

[0049] Please see attached Figure 3 and attached Figure 5The grabbing assembly includes a first hydraulic cylinder 301, which is fixedly installed on the outside of the second swing arm 404. The outer surface of the second swing arm 404 is fixedly connected to a support frame 303, and the end of the support frame 303 is fixedly connected to a fixed plate 302. The output end of the first hydraulic cylinder 301 is fixedly connected to a support seat 306, and the outer side of the support seat 306 is rotatably connected to a plurality of second connecting rods 305, and the outer side of the second connecting rod 305 is rotatably connected to the first connecting rod 304.

[0050] One end of each of the four first connecting rods 304 is rotatably connected to the outer side of the fixing plate 302 , and a rubber pad is provided on the inner side of the second connecting rod 305 .

[0051] Specifically, after the cutting of the raw stone is completed, the connecting frame 407 is rotated 90 degrees through the second electric turntable 409, and the grabbing assembly works at this time. The supporting seat 306 is moved by starting the first hydraulic cylinder 301, so that one end of the multiple second connecting rods 305 is swung, and the second connecting rods 305 are opened outward under the traction of the first connecting rod 304. When the cut raw stone contacts the inner side of the second connecting rod 305, the output end of the first hydraulic cylinder 301 is contracted. At this time, the four second connecting rods 305 are contracted inward to fix the raw stone, and then the raw stone is placed on the placement box 2 in cooperation with the multi-angle cutting assembly.

[0052] A dust reduction component is installed on the outside of the multi-angle cutting component to reduce the dust generated during the cutting of raw stones in the mine;

[0053] Please see attached Figure 2 , Attachment Figure 4 and attached Figure 8 The dust reduction component includes a water tank 509 and a support plate 506. The water tank 509 is fixedly connected to the outer side of the first swing arm 402, and the support plate 506 is fixedly connected to the outer side of the connecting frame 407. The inner side of the support plate 506 is fixedly connected with a fixed cylinder 504, and the interior of the fixed cylinder 504 is slidably connected with a rubber piston 508, and the outer side of the rubber piston 508 is fixedly connected with a movable column 505. The outer side of the fixed cylinder 504 is connected with a second connecting pipe 503, and the outer side of the fixed cylinder 504 is also connected with a first connecting pipe 501. Check valves 507 are installed on the inner sides of the first connecting pipe 501 and the second connecting pipe 503. One end of the first connecting pipe 501 is fixedly connected with an atomizing nozzle 502. The conducting directions of the two check valves 507 are opposite, and one end of the second connecting pipe 503 is connected to the outer side of the water tank 509.

[0054] Specifically, the water tank 509 is the water source of the system, which is compactly designed and fixed on the outside of the first swing arm 402, so as to provide the required amount of water when the equipment is running. The water tank 509 can contain enough water to support long-term dust reduction operations and ensure the continuous operation of the system.

[0055] The rubber piston 508 slides in the fixed cylinder 504 and has good sealing and elasticity, ensuring that no water leakage occurs during the up and down movement of the movable column 505. The design of the rubber piston 508 enables it to effectively absorb water in the water storage tank 509 under negative pressure and discharge the water under positive pressure.

[0056] The first connecting pipe 501 and the second connecting pipe 503 are respectively connected to the inside and outside of the fixed cylinder 504, and are designed with a one-way valve 507, which ensures the one-way flow of water. The design of the atomizing nozzle 502 allows the water to be refined into mist, increasing the contact area between water and air, thereby improving the dust reduction effect. The atomized water mist can quickly absorb dust in the air, reduce the concentration of particulate matter in the air, and reduce the harm to workers.

[0057] When the movable column 505 moves downward, it drives the rubber piston 508 to move downward along the inner wall of the fixed cylinder 504, causing negative pressure to form inside the fixed cylinder 504. This negative pressure state causes the water in the water tank 509 to flow into the fixed cylinder 504 through the second connecting pipe 503. During the upward movement of the rubber piston 508, the water inside the fixed cylinder 504 is forced to be discharged and transported to the atomizing nozzle 502 through the first connecting pipe 501. The atomizing nozzle 502 atomizes the water into tiny water droplets and sprays them evenly on the surface of the cutting saw blade 406. The sprayed water mist can effectively capture and settle dust particles in the air, thereby reducing the risk of workers inhaling harmful particles. This not only protects the health of the workers, but also improves the air quality around the mining area and creates a safer working environment.

[0058] The driving component is installed on the outside of the dust reduction component and is used for driving the dust reduction.

[0059] Please see attached Figure 7 The driving assembly includes a spring 603, a contact plate 601 and an eccentric wheel 602. The spring 603 is sleeved on the outer side of the movable column 505. The contact plate 601 is fixedly connected to the bottom end of the movable column 505. The eccentric wheel 602 is fixedly connected to the other output end of the dual-axis servo motor 408. The outer surface of the eccentric wheel 602 is connected to the outer side of the contact plate 601. The top end of the spring 603 is fixedly connected to the outer side of the support plate 506, and the bottom end of the spring 603 is fixedly connected to the top of the contact plate 601.

[0060] Specifically, the elastic properties of the spring 603 ensure that the movable column 505 can quickly return to the initial position after completing the movement, providing a stable basis for continuous cutting.

[0061] Specifically, during the process of cutting the rough stone, as the output end of the dual-axis servo motor 408 is started, the eccentric rotation of the eccentric wheel 602 will cause the displacement of the contact plate 601. Under the reset action of the spring 603, the movement of the contact plate 601 will directly drive the movable column 505 to move upward or downward, thereby driving the dust reduction assembly.

[0062] Please see attached Figure 2 A control box 7 is installed on the outside of the placement box 2, and the control box 7 is electrically connected to the dual-axis servo motor 408, the first hydraulic cylinder 301, and the second hydraulic cylinder 403 respectively.

[0063] Specifically, the main function of the control box 7 is to centrally manage and control the electrical and hydraulic systems of the mining machine. The control box 7 is electrically connected to the dual-axis servo motor 408, the first hydraulic cylinder 301 and the second hydraulic cylinder 403 to achieve precise control of the cutting and handling process.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
