[0024] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] Currently, vertical shaft loading systems, both domestically and internationally, mainly fall into two categories: fixed-weight hopper (fixed-volume, fixed-weight, vertical loading) and belt conveyor fixed-weight loading (horizontal loading). Among them, belt conveyor fixed-weight loading (horizontal loading) is further subdivided into three types: quantitative weighing coal feeder + belt conveyor, belt conveyor equipped with high-precision belt scale loading system, and fixed-weight belt conveyor (plate chain conveyor) loading system (equipped with weighing sensors).

[0026] While fixed-weight bucket technology is mature, the drawbacks of large-capacity fixed-weight buckets are becoming increasingly apparent as vertical shafts become deeper and hoisting containers become larger. The main drawbacks are increased shaft depth, leading to longer hoisting times; large fixed-weight buckets also have large dimensions, making support difficult and construction challenging if the surrounding rock conditions are poor, resulting in high mining construction costs.

[0027] In recent years, the application of fixed-weight loading belt conveyors has gradually increased. The two methods of using a weighing feeder + loading belt conveyor, and a belt conveyor with a belt scale loading system, have relatively poor accuracy and require significant maintenance. Fixed-weight belt conveyor (plate chain conveyor) loading systems are expensive, bulky, and require a large number of weighing sensors.

[0028] like Figure 1 and Figure 2 As shown in the figure, this disclosure proposes a small-capacity rapid quantitative weighing vertical shaft loading system, including: a weighing device 2, a belt conveyor 3, a first gate 4, and a second gate 5. The feeding end of the weighing device 2 is connected to the discharging end of the coal bunker 1, and the weighing device 2 is used to weigh the discharging weight of the coal bunker 1. The capacity of the weighing device 2 is less than a preset capacity. The feeding end of the belt conveyor 3 is connected to the discharging end of the weighing device 2, and the belt conveyor 3 is used to transport the discharging of the coal bunker 1 to the skip 7. The first gate 4 is located between the feeding end of the weighing device 2 and the discharging end of the coal bunker 1, and the first gate 4 is used to selectively open the passage between the feeding end of the weighing device 2 and the discharging end of the coal bunker 1. The second gate 5 is located between the feeding end of the belt conveyor 3 and the discharging end of the weighing device 2, and the second gate 5 is used to selectively open the passage between the feeding end of the belt conveyor 3 and the discharging end of the weighing device 2.

[0029] It is understandable that, since the feed end of the weighing device 2 is connected to the discharge end of the coal bunker 1, and the feed end of the belt conveyor 3 is connected to the discharge end of the weighing device 2, the discharge from the coal bunker 1 can reach the skip 7 through the weighing of the weighing device 2 and the conveying of the belt conveyor 3, thereby realizing loading and transfer. At the same time, since the first gate 4 is set between the feed end of the weighing device 2 and the discharge end of the coal bunker 1, the first gate 4 can selectively open the passage between the feed end of the weighing device 2 and the discharge end of the coal bunker 1. And since the second gate 5 is set between the feed end of the belt conveyor 3 and the discharge end of the weighing device 2, the second gate 5 can selectively open the passage between the feed end of the belt conveyor 3 and the discharge end of the weighing device 2.

[0030] Therefore, by opening and closing the first gate 4 and the second gate 5, and by weighing in conjunction with the weighing device 2, it is possible to achieve rapid quantitative weighing of small-volume coal discharged from the coal bunker 1. This, in conjunction with the belt conveyor 3, enables high-precision loading of materials. At the same time, it avoids the need for a large number of sensors on the belt conveyor 3, thereby effectively reducing the loading cost of materials.

[0031] It should be noted that the first gate 4 and the second gate 5 work together to achieve fixed-weight discharge from the coal bunker 1. Specifically, when the first gate 4 is open and the second gate 5 is closed, the coal from the bunker 1 enters the fixed-weight device 2, and the detected weight of the fixed-weight device 2 continuously increases until the discharge weight of the coal from the bunker 1 reaches the preset weight. At this point, the first gate 4 closes and the second gate 5 opens, thereby stopping the feeding of the fixed-weight device 2 and starting the discharge of the fixed-weight device 2. Thus, by switching the opening and closing states of the first gate 4 and the second gate 5, the discharge weight of the coal from the bunker 1 is always the preset weight, thereby achieving fixed-weight discharge. In other words, by using the loading system provided in this embodiment, the belt conveyor 3 can achieve multiple quantitative feedings through the coordinated action of the first gate 4 and the second gate 5, thereby achieving high-precision and high-efficiency loading of materials.

[0032] The weighing device 2 is used to weigh the discharged material from the coal bunker 1. In conjunction with the opening and closing of the first gate 4 and the second gate 5, it enables fixed-weight discharge. The specific type of the weighing device 2 can be set according to actual needs and is not limited thereto. The capacity of the weighing device 2 can be less than the preset capacity to achieve rapid quantitative weighing of small volumes. Specifically, the mass range of materials that the weighing device 2 can hold can be 1t-5t. The weighing device 2 can be arranged vertically.

[0033] The belt conveyor 3 is used to transport the coal from the coal bunker 1 to the skip 7. The specific type of the belt conveyor 3 can be set according to actual needs and is not limited thereto. The belt conveyor 3 can be arranged in a horizontal direction.

[0034] The skip 7 is used to load the material discharged from the coal bunker 1. The specific type of skip 7 can be set according to actual needs and there is no restriction. For example, the skip 7 can be a skip. The skip is placed at the discharge end of the belt conveyor 3. After the material is weighed and discharged multiple times by the weighing device 2 and conveyed by the belt conveyor 3, the skip is lifted up.

[0035] The first gate 4 is used to selectively open the passage between the feed end of the fixed weight device 2 and the discharge end of the coal bunker 1. The specific type of the first gate 4 can be set according to actual needs and there is no restriction. For example, the first gate 4 adopts the form of a slide gate, and the switching power of the slide gate can be provided by a hydraulic system. The hydraulic system adopts a high-flow cartridge valve. In addition, the switching of the slide gate can also be driven by a high-speed heavy-duty electric cylinder.

[0036] The second gate 5 is used to selectively open the passage between the feed end of the belt conveyor 3 and the discharge end of the weighing device 2. For example, the second gate 5 is in the form of a slide gate, and the opening and closing power of the slide gate can be provided by a hydraulic system. The hydraulic system uses a high-flow cartridge valve. Alternatively, the opening and closing of the slide gate can also be driven by a high-speed heavy-duty electric cylinder.

[0037] The opening and closing of the first gate 4 and the second gate 5 can be controlled by a control system. Specifically, the signal input terminal of the control system is connected to the signal output terminal of the weighing device 2, and the signal output terminal of the control system is connected to the signal input terminals of the first gate 4 and the second gate 5, respectively. The control system controls the opening of the first gate 4 and the closing of the second gate 5 based on the weight measured by the weighing device 2, and also controls the closing of the first gate 4 and the opening of the second gate 5. After controlling the closing of the first gate 4 and the opening of the second gate 5, the control device can determine whether the weighing device 2 has completed discharging based on the weight measured by the weighing device 2. If it is determined that discharging has been completed, it controls the opening of the first gate 4 and the closing of the second gate 5 again to begin the next cycle of weighing discharging.

[0038] The specific type of control system can be set according to actual needs, and there are no restrictions on it. For example, the control system can be a PLC centralized control system.

[0039] like Figure 2As shown, in some embodiments, the weighing device 2 includes: a first support frame 21, a weighing hopper body 22, and a weighing sensor (not shown in the figure). The first support frame 21 is mounted on the belt conveyor 3, the weighing hopper body 22 is mounted on the first support frame 21, and the feed end of the weighing hopper body 22 is located below the discharge end of the coal bunker 1 and is provided with a first gate 4. The discharge end of the weighing hopper body 22 is located above the feed end of the belt conveyor 3 and is provided with a second gate 5. The weighing sensor is located between the weighing hopper body 22 and the first support frame 21, and the weighing sensor is used to weigh the discharge weight of the coal bunker 1.

[0040] It is understandable that, since the feed end of the fixed-weight hopper body 22 is located below the discharge end of the coal bunker 1 and is equipped with a first gate 4, when the first gate 4 is opened, the discharge end of the coal bunker 1 and the feed end of the fixed-weight hopper body 22 can be connected, thereby realizing the discharge of coal from the coal bunker 1 to the fixed-weight hopper body 22; since the discharge end of the fixed-weight hopper body 22 is located above the feed end of the belt conveyor 3 and is equipped with a second gate 5, when the second gate 5 is opened, the discharge end of the fixed-weight hopper body 22 and the feed end of the belt conveyor 3 can be connected, thereby realizing the discharge of fixed-weight hopper body 22 to the belt conveyor 3; since the weighing sensor is set between the fixed-weight hopper body 22 and the first support frame 21, the weighing sensor can weigh the discharge weight of the coal bunker 1.

[0041] Therefore, by combining the first gate 4, the second gate 5 and the weighing sensor, the rapid quantitative weighing of the coal discharged from the coal bunker 1 can be achieved, and then, in conjunction with the belt conveyor 3, the high-precision loading of the material can be achieved.

[0042] It should be noted that the first support frame 21 is used to support the fixed-weight bucket body 22, weighing sensors, etc. The specific type of the first support frame 21 can be set according to actual needs and is not limited thereto. Among them, the first support frame 21 can be set on the second support frame of the belt conveyor 3.

[0043] The fixed-weight hopper body 22 is used to transfer materials. The specific type of the fixed-weight hopper body 22 can be set according to actual needs and there is no restriction. For example, the fixed-weight hopper body 22 is a prism or frustum structure, which can be arranged on the first support frame 21 through the cooperation of components such as supports, so as to realize the accurate weighing of the weighing sensor.

[0044] The load cell is used to weigh the discharged weight of coal bunker 1 and converts the weighed weight into an electrical signal, which is then sent to the control system. This allows the control system to control the first gate 4, the second gate 5, and the belt conveyor 3 based on the discharged weight of coal bunker 1. The specific type of load cell can be set according to actual needs and is not limited thereto. The load cell accuracy can be C10, ensuring the overall system loading accuracy is ±0.1%.

[0045] Multiple weighing sensors can be arranged evenly between the fixed-weight hopper body 22 and the first support frame 21. Thus, by using multiple weighing sensors, the output weight of the coal bunker 1 can be weighed more accurately.

[0046] like Figure 1 As shown, in some embodiments, the belt conveyor 3 includes: a second support frame (not shown), a drive roller 31, a driven roller 32, a belt 33, and a drive mechanism (not shown). The second support frame is disposed between the coal bunker 1 and the skip 7, and the balancing device 2 is disposed at one end of the second support frame near the coal bunker 1. The drive roller 31 is rotatably disposed at one end of the second support frame near the skip 7, and the driven roller 32 is rotatably disposed at one end of the second support frame near the coal bunker 1. The belt 33 is wound around the drive roller 31 and the driven roller 32. The drive end of the drive mechanism is connected to the drive roller 31, and the drive mechanism is used to drive the belt 33 to rotate so that the bearing surface of the belt 33 moves along the direction from the coal bunker 1 to the skip 7.

[0047] It is understandable that, since the drive roller 31 and the driven roller 32 are respectively rotatably mounted at one end of the second support frame near the skip 7, and the belt 33 is wound around the drive roller 31 and the driven roller 32, and the drive end of the drive mechanism is connected to the drive roller 31, the belt 33 can rotate under the support and guidance of the drive roller 31 and the driven roller 32 and in conjunction with the drive of the drive mechanism, thereby realizing the conveying and loading of materials by moving the bearing surface along the direction from the coal bunker 1 to the skip 7.

[0048] It should be noted that the second support frame is used to support the drive roller 31, driven roller 32, drive mechanism, and fixed weight device 2, etc. The specific type of the second support frame can be set according to actual needs and there is no limitation. For example, the second support frame includes: a connected head frame, intermediate frame, support legs and tail frame. The drive roller 31 is rotatably set at the end of the head frame near the skip 7, and the driven roller 32 is rotatably set at the end of the tail frame near the coal bunker 1.

[0049] The drive roller 31 is used to support the guide belt 33 and to drive the belt 33 to rotate in conjunction with the drive mechanism. The specific type of the drive roller 31 can be set according to actual needs and there is no limitation on it.

[0050] The driven roller 32 is used to support the guide belt 33. The specific type of the drive roller 31 can be set according to actual needs and is not limited thereto.

[0051] The belt 33 is used to rotate in cooperation with the drive roller 31 and the driven roller 32 to realize the conveying of materials. The belt 33 has a bearing surface (upper) and a return surface (lower). The specific type of belt 33 can be set according to actual needs and there is no limitation thereto.

[0052] The drive mechanism is used to drive the drive roller 31 to rotate so that the belt 33 can convey materials. The specific type of drive mechanism can be set according to actual needs and there is no limitation. For example, the drive mechanism can be a combination drive mechanism of drive motor and reducer, or it can be a hydraulic motor, permanent magnet electric roller, etc.

[0053] like Figure 1 As shown, in some embodiments, the belt conveyor 3 further includes a fully enclosed guide trough 34, which is disposed on the second support frame and covers the bearing surface of the belt 33.

[0054] Understandably, since the fully enclosed guide chute 34 is set on the second support frame and covers the bearing surface of the belt 33, the bearing surface of the belt 33 can form a relatively enclosed conveying space using the fully enclosed guide chute 34, thereby ensuring stable and efficient material conveying.

[0055] It should be noted that the fully enclosed guide chute 34 is used to cover the bearing surface of the belt 33, so as to form a relatively enclosed material conveying space on the bearing surface of the belt 33. The specific type of the fully enclosed guide chute 34 can be set according to actual needs and there is no limitation thereto. The fully enclosed guide chute 34 is set on the intermediate frame of the second support frame.

[0056] In some embodiments, the belt conveyor 3 further includes: a plurality of support rollers, which are rotatably mounted on a second support frame and are spaced apart between the drive roller 31 and the driven roller 32, and the belt 33 is wound around the plurality of support rollers.

[0057] It is understandable that, since the support rollers are rotatably mounted on the second support frame and multiple support rollers are spaced apart between the drive roller 31 and the driven roller 32, and the belt 33 is wound around multiple support rollers, the portion of the belt 33 located between the drive roller 31 and the driven roller 32 can be supported by multiple support rollers, thereby ensuring stable and efficient material conveying.

[0058] It should be noted that the support rollers are used to support and guide the belt 33. The specific type of support rollers can be set according to actual needs and there are no restrictions on it. The support rollers are set on the intermediate frame of the second support frame.

[0059] like Figure 1As shown, in some embodiments, the loading system further includes a chute 6, the inlet end of which is connected to the outlet end of the belt conveyor 3, and the outlet end of the chute 6 is connected to the inlet end of the skip 7.

[0060] Understandably, since the feed end of the chute 6 is connected to the discharge end of the belt conveyor 3, and the discharge end of the chute 6 is connected to the feed end of the skip 7, the chute 6 can guide the material output from the belt conveyor 3 to the feed end of the skip 7, thereby ensuring the stable loading of the belt conveyor 3 into the skip 7.

[0061] It should be noted that chute 6 is used for guiding materials, and the specific type of chute 6 can be set according to actual needs without restriction. Chute 6 can be arranged vertically.

[0062] In some embodiments, the chute 6 includes a first channel, a second channel, a third channel, and a flap device. The feed end of the first channel is connected to the discharge end of the belt conveyor 3. The feed end of the second channel is connected to the discharge end of the first channel and the discharge end of the second channel is connected to the feed end of the first skip. The feed end of the third channel is connected to the discharge end of the first channel and the discharge end of the third channel is connected to the feed end of the second skip. The flap device is disposed between the discharge end of the first channel and the feed ends of the second and third channels, and the flap device is used to connect the first channel and the second channel, or connect the first channel and the third channel.

[0063] It is understandable that, since the feed end of the first channel is connected to the discharge end of the belt conveyor 3, and the discharge end of the first channel is connected to the feed end of the second channel and the feed end of the third channel respectively, the chute 6 forms a Y-shaped three-way structure. Furthermore, since the flap device is set between the discharge end of the first channel and the feed end of the second and third channels, the flap device can selectively open the passage between the first channel and the second and third channels respectively.

[0064] When the tipping device connects the first and second channels, the material conveyed by the belt conveyor 3 is loaded into the first skip through the first and second channels; when the tipping device connects the first and third channels, the material conveyed by the belt conveyor 3 is loaded into the second skip through the first and third channels. Thus, through the structural arrangement of the Y-shaped chute 6 and the switching of the tipping device's pathways, the material discharged from the belt conveyor 3 can be loaded into either the first or second skip, making the loading system more efficient and flexible.

[0065] It should be noted that the first channel is used for feeding material into chute 6, while the second and third channels are used for discharging material from chute 6. The specific types of the first, second, and third channels can be set according to actual needs and are not restricted. Among them, the first channel is located at the top, while the second and third channels are located below the first channel.

[0066] The flip-plate device is used to switch between the passage between the first and second channels and between the first and third channels. The specific type of flip-plate device can be set according to actual needs and is not limited thereto. For example, the flip-plate device includes: a flip plate and a hydraulic cylinder that drives the flip plate to rotate. The flip plate is hinged to the discharge end of the first channel, and the hydraulic cylinder and the flip plate are connected in a transmission.

[0067] In some embodiments, the coal bunker 1 is provided with multiple discharge ends, and the loading system includes multiple weighing devices 2, the feed ends of the multiple weighing devices 2 are respectively connected to the multiple discharge ends of the coal bunker 1, and the discharge ends of the multiple weighing devices 2 are respectively connected to the feed ends of the belt conveyor 3.

[0068] It is understandable that, since the feed ends of multiple weighing devices 2 are connected to the discharge ends of coal bunker 1 respectively, and the discharge ends of multiple weighing devices 2 are connected to the feed ends of belt conveyor 3 respectively, the discharge of coal bunker 1 can be weighed using multiple weighing devices 2, thereby effectively improving the loading efficiency of materials.

[0069] It should be noted that the number of discharge ends of coal bunker 1 and the number of weighing devices 2 can be set according to actual needs, and there are no restrictions on this.

[0070] One of the fixed-weight devices 2 can correspond to one discharge end of the coal bunker 1 or multiple discharge ends of the coal bunker 1.

[0071] Each weighing device 2 corresponds to a set of first gates 4 and second gates 5. The loading system includes multiple weighing devices 2, and correspondingly, multiple sets of corresponding first gates 4 and second gates 5.

[0072] In some embodiments, the coal bunker 1 is provided with a first discharge end, a second discharge end, a third discharge end and a fourth discharge end. The first discharge end and the second discharge end are distributed at intervals along the width direction of the belt conveyor 3, the third discharge end and the fourth discharge end are distributed at intervals along the width direction of the belt conveyor 3, the first discharge end and the third discharge end are distributed at intervals along the length direction of the belt conveyor 3, and the second discharge end and the fourth discharge end are distributed at intervals along the length direction of the belt conveyor 3.

[0073] The loading system includes a first fixed-weight device and a second fixed-weight device. The first fixed-weight device and the second fixed-weight device are distributed at intervals along the length direction of the belt conveyor 3. The first feed end of the first fixed-weight device is connected to the first discharge end of the coal bunker 1, the second feed end of the first fixed-weight device is connected to the second discharge end of the coal bunker 1, the first feed end of the second fixed-weight device is connected to the third discharge end of the coal bunker 1, and the second feed end of the second fixed-weight device is connected to the fourth discharge end of the coal bunker 1.

[0074] Understandably, since the first feed end of the first fixed-weight device is connected to the first discharge end of coal bunker 1, and the second feed end of the first fixed-weight device is connected to the second discharge end of coal bunker 1, the first fixed-weight device can achieve fixed-weight discharge from the first and second discharge ends of coal bunker 1. Similarly, since the first feed end of the second fixed-weight device is connected to the third discharge end of coal bunker 1, and the second feed end of the second fixed-weight device is connected to the fourth discharge end of coal bunker 1, the second fixed-weight device can achieve fixed-weight discharge from the third and fourth discharge ends of coal bunker 1. Therefore, through the discharge from the first, second, third, and fourth discharge ends of coal bunker 1, and the weighing by the first and second fixed-weight devices, a high loading efficiency can be achieved in the loading system.

[0075] It should be noted that both the first weighing device and the second weighing device are weighing devices 2 equipped with the first gate 4 and the second gate 5, respectively, and are used for weighing materials.
