Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shovels, in particular to a loader shovel with material recognition function and method. BACKGROUND

[0002] In the process of mining and loading, the loader shovel is one of the key equipment. The traditional loader shovel has a single function, mainly focusing on the mining and loading of ore. However, there are many problems in the actual operation process that need to be solved.

[0003] In the process of mining, it is difficult to accurately grasp the resistance of the shovel. Due to the difference in hardness and density of different ores, the shovel will be subjected to different degrees of resistance in the process of digging. If the resistance cannot be understood in time, the shovel may encounter too much resistance, which not only damages the shovel body and digging teeth, but also may cause the loader to be in an overload state, affecting the normal operation and service life of the equipment.

[0004] A large amount of dust will be generated in the process of mining, which will float in the air and seriously pollute the working environment, causing harm to the health of the operators. At the same time, the dust will also affect the normal operation of the equipment and accelerate the wear and tear of the equipment. Most of the existing shovels lack effective dust reduction measures and cannot effectively solve the problem of dust flying.

[0005] After the shovel loads the ore, small particles of ore are easily stuck in the dead angle position of the inner wall of the shovel, which not only reduces the effective loading capacity of the shovel, but also increases the kinetic energy consumption when the shovel is empty. Moreover, the inner wall of the shovel is easy to attach damp dust during operation, which will affect the normal use and internal cleanliness of the shovel if not cleaned in time.

[0006] The traditional shovel has shortcomings in identifying the type of mined ore, and cannot adjust the mining strategy according to the type of ore, resulting in low mining efficiency. Therefore, it is of great practical significance to develop a loader shovel with multiple functions that can solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all.

[0046] In one embodiment: refer to Figures 1-10 , the loader bucket relates to the bucket technical field, mainly including a bucket body 1, a detection structure, a dust falling structure, a cleaning structure and a vibration structure and the like. Each part cooperates with each other to realize various functions of the bucket in the ore mining and loading process.

[0047] Refer to Figure 2 , Figure 9 and Figure 10, the bucket body 1 is the basic structure of the whole device, and its shape and size are designed according to the actual operation requirements. The bucket body 1 is provided with a plurality of digging teeth 4 at one end, which is used for digging ore when mining. The inner walls of the two sides of the bucket body 1 away from each other are provided with arc-shaped guide plates 21, and the curvature of the arc-shaped guide plates 21 matches the curvature of the inner wall of the bucket body 1, so as to ensure that the arc-shaped guide plates 21 can tightly fit the inner wall for cleaning work. The two ends of the bucket body 1 are fixed with protective isolation covers 25, which are used for protecting part of the internal structure, preventing damage caused by collision with external objects during operation.

[0048] With reference to Figures 3-5 and Figure 7 , the detection structure is used for detecting the resistance of the bucket during mining, mainly including a rectangular hydraulic oil tank 2, a piston pressing plate 3, a digging tooth 4, a pressure sensing sensor 7, a bottom base plate 6 and an industrial monitoring camera 37. The rectangular hydraulic oil tank 2 is arranged at a position close to the bottom of one side of the bucket body 1, and the piston pressing plate 3 is sealingly and slidably connected in the rectangular hydraulic oil tank 2. The rectangular hydraulic oil tank 2 is provided with a plurality of sliding guide grooves 32 on one side, and the plurality of digging teeth 4 are respectively slidably penetrated through the corresponding sliding guide grooves 32, and one end of each of the plurality of digging teeth 4 is fixedly connected with the piston pressing plate 3. When the bucket is used for mining, the digging tooth 4 touches the ore and exerts pressure on the piston pressing plate 3, so that the piston pressing plate 3 extrudes the hydraulic oil in the rectangular hydraulic oil tank 2.

[0049] With reference to Figure 5 and Figure 7 , a plurality of pressure sensing sensors 7 are fixedly embedded in the inner wall of the side of the rectangular hydraulic oil tank 2 away from the piston pressing plate 3, and one side of each of the plurality of pressure sensing sensors 7 is fixedly connected with the same bottom base plate 6, and the bottom base plate 6 is sealingly and slidably connected in the rectangular hydraulic oil tank 2. When the piston pressing plate 3 extrudes the hydraulic oil, the hydraulic oil transmits the extrusion force to the pressure sensing sensor 7 through the bottom base plate 6, and the pressure sensing sensor 7 converts the pressure signal into an electric signal for subsequent processing and analysis. The pressure sensing sensor 7 selects a sensor with a range of 0-100MPa and an accuracy of ±0.5%, which can accurately measure different sizes of pressure.

[0050] With reference to Figure 3 and Figure 5The inner wall of one side of the bucket body 1 is provided with a mounting fixed groove 35, the inner wall of one side of the mounting fixed groove 35 is fixedly provided with an industrial monitoring camera 37, and the mounting fixed groove 35 is fixedly provided with a tempered transparent glass 36 for protecting the industrial monitoring camera 37. The industrial monitoring camera 37 can capture specific details in the mining process in real time and identify the type of mined ore. During the operation process, the industrial monitoring camera 37 transmits the captured image information to the control system, and the control system judges the type of ore according to the image information. At the same time, combined with the resistance detected by the pressure sensing sensor 7 in the mining process, the control system can adjust the power of driving the bucket body 1 to dig. For example, when it is detected that the resistance is large and the type of ore is ore with high hardness, the control system appropriately increases the digging power; on the contrary, when the resistance is small and the type of ore is ore with low hardness, the control system appropriately reduces the digging power. In addition, by analyzing the pressure detected by the pressure sensing sensor 7 and the ore information captured by the industrial monitoring camera 37, it can also be judged that which position on the mining path has smaller mining resistance, so as to adjust the mining path, improve the mining efficiency, and avoid that the bucket body 1 and the digging teeth 4 are damaged and the loader is in an overload state due to too large resistance encountered by the bucket body 1.

[0051] With reference to Figure 2 , Figure 6 and Figure 8 , the dust falling structure is used for dust falling of flying dust when mining ore, mainly including a liquid storage container pipe 10, atomizing spray nozzles 12, device bases 8, rotating rotating rods 9, liquid injection pipes 13, torsion springs 11, pull ropes I 14, heavy steel balls 15 and triangular grooves 16 and the like. The liquid storage container pipe 10 is rotationally arranged at the top of the bucket body 1, and a plurality of atomizing spray nozzles 12 are fixed to the outer wall of the liquid storage container pipe 10. The atomizing spray nozzles 12 are used to spray the water in the liquid storage container pipe 10 after atomization, so as to realize the dust falling function. Two device bases 8 are fixed to the top of the bucket body 1, and the two device bases 8 are rotationally connected with the rotating rotating rods 9 on the side close to each other. The two rotating rotating rods 9 are fixedly connected with the two ends of the liquid storage container pipe 10 on the ends close to each other. The liquid injection pipe 13 is arranged to penetrate through one of the device bases 8, and one end of the liquid injection pipe 13 is connected with a water source outside, and the other end of the liquid injection pipe 13 is rotationally penetrated through the corresponding rotating rotating rod 9 and rotationally communicated with the liquid storage container pipe 10, so as to inject water into the liquid storage container pipe 10. The outer wall of each of the two rotating rotating rods 9 is sleeved with a torsion spring 11, and the torsion range of the torsion spring 11 is 5-15 N·m.

One side of the bucket body 1 is provided with a plurality of triangular grooves 16, and the heavy steel ball 15 is rollingly arranged in the triangular groove 16.

[0053] In the operation process, when the opening of the bucket body 1 is horizontally placed, at this time the torsional force of the torsion spring 11 is greater than the gravity of the heavy steel ball 15 inclined sliding, the liquid storage container tube 10 is kept stable under the action of the torsion spring 11, driving the atomized spray nozzle 12 to spray water droplets in the direction of the opening of the bucket body 1, thereby dust reduction in the mining process, avoiding dust flying, polluting the air. When the bucket body 1 is fully loaded with ore, the opening of the bucket body 1 is turned upward, at this time the heavy steel ball 15 falls downward under the action of the triangular groove 16, the gravity of the heavy steel ball 15 is greater than the torsional force of the torsion spring 11, the liquid storage container tube 10 drives the atomized spray nozzle 12 to rotate 180°, the direction of the atomized spray nozzle 12 is reversed and located below the liquid storage container tube 10, avoiding the damage of the atomized spray nozzle 12 caused by the overflow of the ore in the bucket body 1.

[0054] Referring to Figure 12 The top of each of the plurality of heavy steel balls 15 is provided with two limiting arc-shaped rods 5, both of which are fixed on the top of the bucket body 1 and used to limit the heavy steel ball 15, avoiding the heavy steel ball 15 from escaping from the triangular groove 16 during the rotation of the bucket body 1, ensuring the normal operation of the dust reduction structure.

[0055] Referring to Figure 2 , Figure 9 and Figure 10 , the cleaning structure is used to drive the arc-shaped guide plate 21 to move along the dead angle of the inner wall of one side of the bucket body 1, and to clean the small particle ore stuck in the dead angle, mainly including a rotating shaft 17, a rotating swing arm 18, a sliding guide block 19, an elastic spring 20, a connecting fixed block 33, a rotating swing plate 22, a pin connecting shaft 23 and a hydraulic power cylinder 24.

The two sides of the bucket body 1 are rotatably connected with a hydraulic power cylinder 24, and the output shafts of the two hydraulic power cylinders 24 are fixedly connected with the corresponding pin connecting shafts 23.

[0057] In the operation process, the output end of the hydraulic power cylinder 24 is telescopic, and the rotating shaft 17 is driven to rotate through the cooperation of the pin connecting shaft 23 and the rotating swing plate 22, and the rotating swing arm 18 is driven to rotate by the rotating shaft 17. The arc-shaped guide plate 21 is always close to the dead corner position of the inner wall of the bucket body 1 under the elastic force of the elastic spring 20 during the rotation of the rotating swing arm 18. When the rotating swing arm 18 rotates, the elastic spring 20 exerts a pushing force on the arc-shaped guide plate 21, so that the arc-shaped guide plate 21 cleans the dead corner of the bucket body 1 and removes the small particle ore stuck. In this way, the bucket body 1 can be loaded with ore to the maximum extent, and the bucket body 1 can run in an empty state when it is not loaded with ore, thereby reducing the consumption of kinetic energy.

[0058] Referring to Figure 2 , Figure 3 and Figure 9 , the vibration structure is used to knock the bucket body 1 when the arc-shaped guide plate 21 is running, so as to shake off the damp dust attached to the inner wall of the bucket body 1, and mainly includes a power transmission rod 27, a synchronous wheel II 28, a synchronous wheel I 26, a synchronous transmission belt 29, a rubber rotating disc 30 and a knocking impact ball 31. The power transmission rod 27 is rotatably connected with the inner wall of the side of the bucket body 1 away from the protective isolation cover 25. The outer wall of the power transmission rod 27 is fixedly sleeved with two synchronous wheel II 28, and the end of the two rotating shafts 17 away from each other is fixedly provided with a synchronous wheel I 26, and the adjacent synchronous wheel I 26 and the synchronous wheel II 28 are transmissionally connected through the synchronous transmission belt 29. The outer wall of the power transmission rod 27 is fixedly sleeved with a plurality of rubber rotating discs 30, and the outer wall of the rubber rotating disc 30 is fixedly provided with a plurality of knocking impact balls 31.

[0059] When the rotating swing arm 18 rotates to remove small particles of ore stuck in the dead angle position in the bucket body 1, the rotating shaft 17 drives the power transmission rod 27 and the rubber rotating disc 30 through the cooperation of the synchronous wheel II 28, the synchronous wheel I 26 and the synchronous transmission belt 29. The rubber rotating disc 30 drives the knocking and colliding ball 31 to rotate continuously, and the knocking and colliding ball 31 knocks the outer wall of the bucket body 1 during rotation, shakes off the wet dust attached to the inner wall of the bucket body 1, ensures the cleanliness of the inside of the bucket body 1, and makes the bucket body 1 run in an empty state when it is not loaded with ore, thereby reducing the consumption of kinetic energy.

[0060] In another embodiment: referring to Figure 11 and Figure 12 , the side of the bucket body 1 near the top is provided with a storage slot 38, and a protective baffle 39 is slidably connected in the storage slot 38. The protective baffle 39 can freely slide in the storage slot 38 to realize the functions of extension and retraction.

[0061] When the liquid storage container tube 10 rotates to change the direction of the atomizing spray nozzle 12, the liquid storage container tube 10 pulls the protective baffle 39 out of the storage slot 38 through the pull rope II 41. The top of the bucket body 1 is provided with a plurality of accommodation through holes 40 connected with the storage slot 38 for accommodating the pull rope II 41. After the protective baffle 39 is pulled out, it is used to prevent ore from falling from one side of the bucket body 1, which not only protects the atomizing spray nozzle 12 and the liquid storage container tube 10, but also increases the loading capacity of the bucket body 1. When the protective baffle 39 is pulled out, the bottom end of the protective baffle 39 can still close the accommodation through hole 40, preventing foreign matter from entering the storage slot 38 and affecting the normal sliding of the protective baffle 39.

[0065] S3, when the liquid storage container tube 10 rotates to reverse the direction of the atomized spray nozzle 12, the liquid storage container tube 10 pulls the protective baffle 39 out of the storage groove 38 through the pull rope II 41, which is used to avoid the ore falling from one side of the bucket body 1, not only can protect the atomized spray nozzle 12 and the liquid storage container tube 10, but also can increase the loading capacity of the bucket body 1, and when the protective baffle 39 is pulled out, the bottom end of the protective baffle 39 can still close the let-hole 40 to avoid the impurities entering the storage groove 38;

[0066] S4, when the bucket body 1 mines the ore, the small particles of ore at the bottom are clamped into the dead angle position of the bucket body 1 under the extrusion of the ore above, and these small particles of ore are still clamped in the dead angle position when the bucket body 1 dumps the ore later, which not only affects the overall loading capacity of the bucket body 1, but also increases the kinetic energy needed for the bucket body 1 to mine, and improves the energy consumption, at this time the output end of the hydraulic cylinder 24 is telescopic, the hydraulic cylinder 24 drives the rotating swing arm 18 to rotate through the cooperation of the pin connection shaft 23 and the rotating swing plate 22, and the arc guide plate 21 always adheres to the inner wall dead angle position of the bucket body 1 under the elastic force of the elastic spring 20 during the rotation of the rotating swing arm 18, thereby removing the clamped small particles of ore, which can make the bucket body 1 load the ore to the maximum extent, and also can make the bucket body 1 run in the empty state when it is not loaded with ore, reducing the consumption of kinetic energy;

[0067] S5, when the bucket body 1 mines ore, the atomized spray nozzle 12 sprays water mist to the dust in the ore, and part of the dust is attached to the inner wall of the bucket body 1 under the action of the water mist, so when the rotating swing arm 18 rotates to remove the small particle ore stuck in the dead angle position in the bucket body 1, the rotating shaft 17 drives the power transmission rod 27 and the rubber rotating disc 30 to rotate through the cooperation of the synchronous wheel II 28, the synchronous wheel I 26 and the synchronous transmission belt 29, the rubber rotating disc 30 knocks the outer wall of the bucket body 1 through the knocking impact ball 31, and the wet dust attached to the inner wall of the bucket body 1 is shaken off, ensuring the cleanliness of the inside of the bucket body 1, so that the bucket body 1 runs in an empty load state when it is not loaded with ore, reducing the consumption of kinetic energy.

10. A method of using a loader bucket with material identification function, applied to the loader bucket with material identification function as described in claim 9, characterized in that, Includes the following steps: S1. The loader mines in the open-pit mine through the bucket body (1). During the mining process of the bucket body (1), the digging teeth (4) at one end of the bucket body (1) touch the ore and squeeze the hydraulic oil in the rectangular hydraulic oil groove (2) through the piston pressure plate (3). The hydraulic oil transmits the pressure to the pressure sensor (7) through the bottom base plate (6). The industrial monitoring camera (37) can capture the specific details of the mining process in real time and check the type of ore being mined. According to the resistance detected by the pressure sensor (7) during the mining process, the power to drive the bucket body (1) to dig is adjusted. In addition, the pressure detected by the pressure sensor (7) is combined with the ore captured by the industrial monitoring camera (37) to determine which position on the mining path has less mining resistance. Thus, the mining path can be adjusted to improve mining efficiency and avoid the bucket body (1) encountering too much resistance, which would cause damage to the bucket body (1) and the digging teeth (4) and the loader being overloaded when the bucket body (1) is mining. S2. During the mining process, the opening of the bucket body (1) is placed horizontally. At this time, the torque of the torsion spring (11) is greater than the gravity of the load-bearing steel ball (15) sliding. At this time, the liquid storage container pipe (10) drives the atomizing spray nozzle (12) to spray atomized water droplets in the direction of the opening of the bucket body (1), thereby reducing dust during the mining process and preventing dust from flying and polluting the air. When the ore on the bucket body (1) is full, the opening of the bucket body (1) rotates upward. At this time, the load-bearing steel ball (15) falls downward under the action of the triangular groove (16). The gravity of the load-bearing steel ball (15) is greater than the torque of the torsion spring (11). The liquid storage container pipe (10) drives the atomizing spray nozzle (12) to rotate 180°. The direction of the atomizing spray nozzle (12) is reversed and it is located below the liquid storage container pipe (10) to prevent the ore in the bucket body (1) from overflowing and falling and causing damage to the atomizing spray nozzle (12). S3. When the liquid storage container tube (10) rotates to change the direction of the atomizing spray nozzle (12), the liquid storage container tube (10) pulls the protective baffle (39) outward from the storage tank (38) through the pull rope II (41) to prevent the ore from falling from one side of the bucket body (1). It can not only protect the atomizing spray nozzle (12) and the liquid storage container tube (10), but also increase the loading capacity of the bucket body (1). When the protective baffle (39) is pulled out, the bottom end of the protective baffle (39) can still close the clearance through hole (40) to prevent external impurities from entering the storage tank (38). S4. When the bucket body (1) is mining ore, the small ore particles located below are squeezed into the dead corner of the bucket body (1) by the gravity of the ore above. When the bucket body (1) dumps the ore later, these small ore particles are still stuck in the dead corner, which not only affects the overall loading capacity of the bucket body (1), but also increases the kinetic energy required for the bucket body (1) to mine, thus increasing energy consumption. At this time, the output end of the hydraulic power cylinder (24) extends and retracts. The hydraulic power cylinder (24) is connected by a pin. The combination of the connecting shaft (23) and the rotating swing plate (22) drives the rotating swing arm (18) to rotate. During the rotation of the rotating swing arm (18), the arc-shaped guide plate (21) is always in close contact with the dead corner of the inner wall of the bucket body (1) under the elastic force of the elastic spring (20), thereby clearing the stuck small particles of ore. This allows the bucket body (1) to load ore to the maximum extent, and also allows the bucket body (1) to operate in an unloaded state when no ore is loaded, reducing the consumption of kinetic energy. S5. When the bucket body (1) is mining ore, the water mist sprayed by the atomizing nozzle (12) settles the dust in the ore. Some of the dust adheres to the inner wall of the bucket body (1) under the action of the water mist. Therefore, when the rotating swing arm (18) rotates to remove small particles of ore stuck in the dead corner of the bucket body (1), the rotating shaft (17) drives the power transmission rod (27) and the rubber rotating disk (30) to rotate through the cooperation of the synchronous wheel II (28), synchronous wheel I (26) and synchronous transmission belt (29). The rubber rotating disk (30) knocks the outer wall of the bucket body (1) by striking the collision ball (31), shaking off the wet dust attached to the inner wall of the bucket body (1), ensuring the cleanliness of the inside of the bucket body (1), so that the bucket body (1) is in an unloaded state when no ore is loaded, reducing the consumption of kinetic energy.
