Description

Technical Field

[0001] The present invention relates to the technical field of ore sorting equipment, and in particular to an ore sorting device. Background Art

[0002] As an important raw material for industry and manufacturing, the mining and utilization of ore is of great significance to economic development. However, natural ores usually contain multiple components, and the economic value of each mineral varies significantly. Therefore, ore sorting is crucial in the initial processing stage after mining. Effective separation of high-value minerals from low-value or useless minerals not only helps to improve resource utilization, but also significantly reduces the cost of subsequent processing.

[0003] In the prior art, many mining areas are still using traditional manual methods to sort ore, but this method has many limitations. First, the processing speed of manual sorting is extremely limited. Relying on manual operation not only reduces the efficiency of ore processing, but also makes it difficult to adapt to the growing scale demand of modern mining production. Secondly, the accuracy of manual sorting is difficult to guarantee, especially when sorting ore by quality and grade classification. Due to the limitations of the human eye's ability to identify minerals and differences in experience, it is difficult to achieve consistent and accurate separation, which leads to the loss of valuable minerals and waste of resources. In addition, the working environment of manual sorting is usually harsh, often accompanied by a large amount of dust, noise and other harmful factors, which not only increases the labor intensity of workers, but also poses a serious threat to their health. Therefore, the existing manual sorting method is not only inefficient and poor in precision, but also has poor working conditions. This situation obviously cannot meet the requirements of modern mining for high efficiency, high precision and safe production.

[0004] Therefore, there is an urgent need to develop an ore sorting equipment that can achieve efficient and accurate ore sorting by accurately sensing the location of the ore, greatly improving the accuracy of ore sorting, and can also sort the ore by quality grade, thereby improving the efficiency of ore sorting, reducing the resource input and cost of manual labor, and optimizing the working environment of ore sorting.

[0027] In this embodiment, the picking unit (2) includes a support base (21) arranged on both sides of the first conveyor belt, a screw module I (22) arranged on the support base (21) and a rotating module (23) vertically connected to the screw module I (22); a screw module II (24) parallel to the second conveyor belt (12) is arranged between the rotating modules (23); a bucket (25) for picking up ore is arranged on the screw module II (24); the height of the screw module I (22) is higher than the working surface height of the first conveyor belt (11), which can ensure that the rotating module (23) vertically connected to the screw module I (22) is higher than the working surface of the first conveyor belt (11), so that the screw module II (24) arranged between the rotating modules (23) is located above the first conveyor belt (11), so that the bucket (25) on the screw module II (24) can effectively pick up the ore on the first conveyor belt (11).

[0028] In this embodiment, the support base (21) is provided with a driving motor I (26) for driving the screw module I (22) to work. The screw module I (22) is used to realize the vertical movement of the rotating module (23), the screw module II (24) and the bucket (25) in the working state; Figure 2As shown, the screw module I (22) is used to realize the vertical movement of the rotating module (23), the screw module II (24) and the bucket (25) in the working state. When the rotating module (23), the screw module II (24) and the bucket (25) are in the working state, the position of the rotating module (23) vertically connected to the screw module I (22) is adjusted in real time in the vertical direction by the driving motor I (26), so that the screw module II (24) and the bucket (25) are synchronously adjusted in the vertical direction. It is ensured that the bucket (25) can effectively act on the working surface of the first conveyor belt (11) in the vertical direction, so as to pick up the ore transported by the first conveyor belt (11).

[0029] In this embodiment, the rotating module (23) includes an axis housing (231) vertically connected to the screw module I (22), a rotating shaft (232) passing through the axis housing (231), and a driving motor II (233) arranged at the outer end of the axis housing (231) and connected to the input end of the rotating shaft (232), and the output end of the rotating shaft (232) is connected to a triangular shaft (234) for realizing the rotational movement of the screw module II (24) and the bucket (25); a slide can be arranged on the screw module I (22), and the slide is used to vertically connect the axis housing (231) to the screw module I (22), and the driving motor II (233) can control the rotation direction and rotation speed of the rotating shaft (232) according to demand, so as to realize the rotational movement of the screw module II (24) and the bucket (25).

[0030] In this embodiment, the triangular shaft (234) is provided with three output ends distributed at an angle of 120° between each other, and the three output ends of the triangular shaft (234) are respectively connected to a rotating disk (236) and a driving motor III (235) for driving the rotating disk (235) to rotate, and the screw module II (24) is connected and installed between the rotating disks (236), and the screw module II (24) is provided with a driving motor IV (241) for driving the screw module II (24) to work, and the rotating disk (236) is used to realize the self-rotation of the screw module II (24), and the screw module II (24) is used to realize the lateral movement of the bucket (25); Figure 2As shown, the triangular shaft (234) is provided with three output ends with an angle of 120° between each other. This layout is used to construct a motion system in a three-dimensional space, and can achieve precise three-dimensional positioning and movement. The 120° distribution makes the overall structure of the rotating module (23) symmetrical, which helps to maintain the balance and stability of the movement. The rotating disks (236) located at both ends of the screw module II (24) are driven to rotate by the driving motor III (235), thereby driving the screw module II (24) to rotate, and the bucket (25) on the screw module II (24) rotates about the rotating axis of the screw module II (24), providing the bucket (25) with a rotational degree of freedom for picking up ore.

[0031] In this embodiment, the bucket (25) is provided with three groups corresponding to the screw module II (24), each screw module II (24) is provided with a screw slide (242), and the screw slide (242) is provided with an electric push rod (243) for connecting the bucket (25); the electric push rod (243) provided on the screw slide (242) can adjust the pitch angle of the bucket (25), when the bucket (25) picks up ore, the electric push rod (243) makes the bottom of the bucket (25) parallel to the first conveyor belt (11) and scoops up the ore, after scooping up the ore, the electric push rod (243) contracts, and the bucket (25) is tilted up to prevent the ore from falling from the bucket (25).

[0032] In this embodiment, a slide groove (251) is provided at the top of the bucket (25), and a movable slider (252) connected to the end of the electric push rod (243) is arranged in the slide groove (251) for adjusting the pitch angle of the bucket (25). A sensor for detecting the quality of the ore in the bucket (25) is arranged at the bottom of the bucket (25); after the bucket (25) scoops up the ore, the bucket (25) is tilted up when the electric push rod (243) contracts. At this time, the ore in the bucket (25) exerts pressure on the bottom of the bucket (25) under the action of gravity, and the quality of the ore scooped up by the bucket (25) is detected through the sensor at the bottom of the bucket (25).

[0033] In this embodiment, the sorting unit (3) comprises a first sorting lever (31) and a second sorting lever (32) which are sequentially arranged along the conveying direction of the second conveyor belt (12); the first sorting lever (31) and the second sorting lever (32) can be driven to move; the first sorting lever (31) is used to perform preliminary sorting of the ore on the second conveyor belt (12); and the second sorting lever (32) is used to perform final sorting of the ore that has been preliminary sorted by the first sorting lever (31).

[0034] In this embodiment, an identification unit (4) is also included, and the identification unit (4) includes an identification device (43), a bracket I (41) spanning the first conveyor belt (11) and located in front of the picking unit (2), and a bracket II (42) spanning the second conveyor belt (12) and located in front of the sorting unit (3). The bracket I (41) is used to set the identification device (43) above the first conveyor belt (11) and detect the position of the ore on the first conveyor belt (11), and the bracket II (42) is used to set the identification device (43) above the second conveyor belt (12) and detect the position of the ore on the second conveyor belt (12). The identification device (43) refers to a device or system capable of identifying specific objects, features or behaviors, such as an industrial camera, an intelligent vision camera, a 3D camera, a linear array camera, a machine vision algorithm software, etc. In this embodiment, the identification device (43) uses an industrial camera to detect the ore on the first conveyor belt (11) and the second conveyor belt (12). The industrial camera can continuously capture multiple image frames and more delicate and clear images at an extremely fast speed, making it play an irreplaceable role in dynamic monitoring, quality inspection and other scenes. Since the ore needs to be sorted, the on-site working environment is relatively harsh.

[0035] The design of industrial cameras fully considers the harsh industrial environment and uses sturdy and durable materials to ensure stable operation under various temperature, humidity, vibration and other conditions. Therefore, industrial cameras are preferred as recognition devices (43).

[0036] In this embodiment, it also includes a storage unit (5) arranged on both sides of the end of the second conveyor belt (12), and the storage unit (4) includes four storage boxes (51) for storing ores of different mass grades, a slide plate (52) for receiving the ores, and a hydraulic rod (53) for supporting the slide plate; the slide plate (52) for receiving the ore is connected between the second conveyor belt (12) and the storage box (51), so that the process of the ore from the second conveyor belt (12) to the storage box (51) has a transition section and plays a buffering role; the hydraulic rod (53) for supporting the slide plate is connected between the storage box (51) and the slide plate (52) for receiving the ore, and the pitch angle of the slide plate (52) can be adjusted by the hydraulic rod (53), thereby improving the applicability of the storage unit (5).

[0037] In this embodiment, a control unit (6) is also included, and the control unit (6) includes an equipment cabinet (63), a control panel (62) and a display panel (61), which is used to realize human-machine interaction of the device; the control unit (6) can make real-time adjustments according to the transportation, picking and sorting conditions of the ore, and on-site staff can also make manual adjustments through the control panel (62).

[0038] In this embodiment, the impurity removal unit (7) is also provided at the starting end of the first conveyor belt (11), and the impurity removal unit (7) includes a crank rocker mechanism (71), a sieve plate (72) fixedly connected to the connecting rod of the crank rocker mechanism (71), and a storage box (73) provided below the crank rocker mechanism (71) and used for receiving impurities screened by the sieve plate (72). A material discharge hopper (8) for discharging materials is suspended directly above the sieve plate (72) through a bracket III (9), and ore falls through the material discharge hopper (8). The ore is passed to the screen plate (72) for impurity removal. The crank rocker mechanism (71) can be driven to make reciprocating motion, so that the connecting rod swings up and down within a certain range. The screen plate (72) makes the same motion as the connecting rod, so that the impurities on the ore are separated from the ore through vibration and fall into the storage box (73) through the small holes on the screen plate (72). The installation position of the screen plate (72) has a certain inclination, so that the ore can be transmitted to the first conveyor belt (11) through its own gravity and the vibration of the screen plate (72).

[0039] In this embodiment, the working principle of the ore sorting device is as follows:

[0040] In the initial state, the ore falls onto the sieve plate (72) through the lower hopper (8), and the ore on the sieve plate (72) is vibrated by the crank rocker mechanism (71) to remove impurities on the surface. The impurities fall through the small holes on the sieve plate (72) and are stored in the storage box (73). The sieve plate (72) then transfers the ore to the first conveyor belt (11). When the first conveyor belt (11) is transporting the ore to the picking unit (2), the identification device (43) installed on the bracket I (41) will identify and record the shape, size, posture and other information of the ore, and send the relevant information of the ore to the control unit (6). The control unit (6) plans the corresponding trajectory and picking strategy based on this information, and then drives the picking unit (2) to move the ore to the picking unit (2). The picking unit (2) and the sorting unit (3) perform corresponding actions. When the picking unit (2) picks up the ore conveyed by the first conveyor belt (11), it will combine the information sent by the identification device (43). The screw module I (22) adjusts the bucket (25) to a suitable picking height by moving it in the vertical direction. The rotating module (23) rotates a group of buckets (25) to a position at the bottom where picking can be performed through a rotating movement. The screw module II (24) adjusts the bucket (25) to a corresponding position of the ore on the first conveyor belt (11) by moving the bucket (25) left and right. At the same time, the screw module II (24) can also make the bucket (25) rotate by itself through the rotating disk (236) to cooperate with the bucket (25) to pick up. During the picking operation, the electric push rod (243) on the bucket (25) can adjust the pitch angle of the bucket (25). When picking up, the electric push rod (243) makes the bottom of the bucket (25) parallel to the first conveyor belt (11) to shovel up the ore. After shoveling up the ore, the electric push rod (243) contracts and tilts the bucket (25) to prevent the ore from falling from the bucket (25). The screw module I (22) starts to lift the bucket (25) upward. The rotating module (23) rotates the bucket (25) to the position of the second conveyor belt (12). After the weight detection sensor on the bucket (25) measures the weight of the ore, it sends the information to the control unit (6). The screw module II (24) moves the bucket (25) left and right to move the bucket (25) upward. The bucket (25) moves to the second conveyor belt (12) for receiving ore of corresponding magnitude, the electric push rod (243) bends the bucket (25), and the ore falls from the bucket (25) onto the corresponding second conveyor belt (12), completing the ore picking step. The three groups of buckets (25) work in a cycle, effectively improving the efficiency of ore picking. If there is too much ore on the first conveyor belt (11) so that the picking unit (2) cannot pick up all the ore transported from the first conveyor belt (11) onto the second conveyor belt (12), the on-site personnel can manually adjust the speed of the first conveyor belt (11) through the control unit (6) to ensure that the picking unit (2) can pick up all the ore transported from the first conveyor belt (11) onto the second conveyor belt (12).

[0041] After the ore is picked up onto the corresponding second conveyor belt (12), the second conveyor belt (12) will transport the ore to the storage box (51). During the transportation process, the ore is further sorted. First, the identification device (43) installed on the bracket II (42) will identify and record the shape, size, posture and other information of the passing ore, and send the relevant information of the ore to the control system. The control system plans the corresponding trajectory and sorting strategy of the sorting unit (3) based on this information. Combined with the weight of the ore measured by the sensor on the bucket (25), the first sorting lever (31) is driven to move the ore on the second conveyor belt (12) to the side of the storage box (51) with the corresponding mass level, completing the first step of ore sorting. Then, the second sorting lever (32) is driven to move the ore onto the slide 42 for receiving the ore connected to the storage box (51) of the corresponding weight level, and finally the slide (52) rolls into the storage box (51), completing the sorting of the ore. The entire sorting system operates continuously and efficiently until all ore sorting tasks are completed.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
