Description

[0001] A horizontally arranged temporary storage bin for mine tunnels Technical Field

[0002] This utility model relates to the field of mining equipment technology, specifically to a horizontally arranged storage bin for temporary storage of materials in a mining tunnel. Background Technology

[0003] In existing mine operations, temporary storage bins are typically installed vertically to the mine shaft, often reaching heights of over 10 meters. This vertical arrangement presents numerous safety hazards. For example, during installation and maintenance, working at height increases the risk of falls. Furthermore, due to their height, they are less stable in complex mine environments, making them susceptible to tilting and collapse caused by mine vibrations and geological changes, posing a serious threat to personnel, equipment, and normal production operations. Moreover, the construction cost of vertical storage bins is high, and once the working face is completed, the bin is discarded. In contrast, the temporary storage bins using this patented device can be disassembled and reused in other working faces. Additionally, vertically arranged storage bins may suffer from low efficiency and high energy consumption in material transfer. Therefore, a new type of temporary mine storage bin is urgently needed to address these issues. Summary of the Invention

[0004] This utility model aims to solve the problems of significant safety hazards, poor stability, and low material transfer efficiency and energy consumption in existing vertically arranged temporary storage compartments for mine tunnels, and provides a horizontally arranged temporary storage compartment for mine tunnels.

[0005] The technical solution to achieve the purpose of this utility model invention is a horizontally arranged temporary storage bin in a mine tunnel, wherein the storage bin is arranged horizontally along the tunnel and is assembled from bin a, bin b and bin c.

[0006] Section A is the input end, section C is the output end, and section B is the intermediate section that connects section A and section C. Section A, also known as the feed hopper, is equipped with buffer rollers, and materials are loaded into the storage hopper from an external mechanism. Section B, also known as the intermediate hopper, can be increased or decreased according to customer requirements and is key to storage capacity. Section C, also known as the unloading hopper, is where materials stored in section A and section B are transported and discharged.

[0007] The section a includes a first frame and a first conveyor shaft mounted on the first frame. A first baffle is provided on each of the two sides and one end face of the upper part of the first frame. A first motor drives the first conveyor shaft to rotate.

[0008] The b-section compartment includes a second frame and a second conveyor shaft mounted on the second frame, with a second baffle on each of the two sides of the upper part of the second frame;

[0009] The c-section compartment includes a third frame and a third conveyor shaft mounted on the second frame, with a third baffle plate on each of the two sides of the upper part of the third frame;

[0010] The first frame, the second frame, and the third frame are connected in sequence. The end of the first frame without the first baffle is connected to the end of the second frame without the second baffle, and the other end of the second frame without the second baffle is connected to the end of the third frame without the third baffle.

[0011] Conveyor belts are provided on the first, second, and third conveyor shafts, and the conveyor belts are driven to move by the rotation of the first conveyor shaft.

[0012] Furthermore, a first motor mounting bracket is also provided on the first frame.

[0013] Furthermore, the c-section compartment also includes a second motor, which drives the third conveyor shaft to rotate.

[0014] Furthermore, a second motor mounting bracket is provided on the third frame;

[0015] The second motor is placed on the second motor mounting bracket.

[0016] Furthermore, the second frame is assembled from at least one smaller frame.

[0017] Furthermore, the second frame is equipped with an intermediate motor, which drives at least one second conveyor shaft to rotate.

[0018] Furthermore, a weighing device is provided on the first frame.

[0019] Furthermore, the weighing device mentioned is an electronic weighing device;

[0020] The electronic weighing device is connected to the first motor and / or the second motor and / or the intermediate motor via a controller.

[0021] Furthermore, a limiter is provided on the first baffle and / or the second baffle and / or the third baffle, and the limiter is connected to the first motor and / or the second motor and / or the intermediate motor by control.

[0022] Furthermore, the storage compartment also includes a d-section compartment, which includes a fourth frame and at least a pair of vertically staggered fourth conveyor shafts mounted on the fourth frame. A fourth baffle is provided on each of the two sides of the upper part of the fourth frame. The fourth conveyor shaft is a bidirectional tensioning roller mechanism, which is a key mechanism to meet the tension of the running belt.

[0023] The d-section warehouse can be located between the c-section warehouse and the b-section warehouse;

[0024] Alternatively, the d-segment compartment can be located between two adjacent b-segment compartments.

[0025] The working principle is as follows: the first motor drives the first conveyor shaft to rotate, thereby transferring the material on the conveyor belt from section a to section b. The intermediate motor can assist the second conveyor shaft to rotate, ensuring the smooth transfer of material in section b. The second motor drives the third conveyor shaft to rotate, realizing the output of material from section b to section c. Section d tensions the belt through two fourth conveyor shafts that are staggered vertically.

[0026] The weighing device can monitor the weight of materials in section A in real time. Through the connection between the controller and the motor, the operation of the motor can be controlled according to the weight of the materials. For example, when the materials reach a certain weight, the motor speed can be adjusted.

[0027] Limiters are provided on the first baffle, the second baffle and / or the third baffle. The limiters are connected to the first motor, the second motor and / or the intermediate motor through control to prevent material from overflowing during the transmission process. Beneficial effects

[0028] High safety: The horizontal layout avoids working at heights, greatly reducing the risk of falls during installation and maintenance. Compared to vertical structures, it offers better stability in complex environments such as mine tunnel vibrations, making it less prone to tilting or collapse, thus ensuring the safety of personnel and equipment within the mine.

[0029] Improved material handling efficiency: Horizontally arranged conveyor belts provide smoother material transport, reducing material jamming and improving efficiency. The operation of each motor section can be flexibly adjusted according to actual needs to further optimize the material handling process.

[0030] Energy saving and consumption reduction: Due to the improved transmission efficiency, the energy consumption of the motor can be effectively controlled, reducing the energy consumption of the entire storage silo during the material transmission process.

[0031] Because it is a modular structure, it can be reused and is easy to move within the tunnel. Attached Figure Description

Detailed Implementation

[0044] Design principle explanation:

[0045] Horizontal layout: The storage warehouse is arranged horizontally along the aisle, abandoning the traditional vertical layout, reducing height and safety risks.

[0046] like Figure 1 As shown, a horizontally arranged temporary storage bin for a mine tunnel comprises bin 1 (a), bin 2 (b), and bin 3 (c) connected and assembled in sequence, with each bin forming a continuous material transfer and storage channel in the horizontal direction.

[0047] Structural characteristics of each section of the warehouse: such as Figure 2 , 5 As shown, section a (input end) has a first frame 11 as its main structure, which supports the first conveyor shaft 12. The first conveyor shaft 12 is mounted on the first frame 11 via bearings to ensure its stable rotation.

[0048] First baffles 13 are provided on the upper two sides and one end face of the first frame 11. The first baffles 13 are made of high-strength steel plates and are welded or threaded onto the frame. The height is determined according to the actual material storage requirements and is generally higher than the material stacking height to prevent the material from overflowing from the sides and front end during the conveying process.

[0049] The first motor is connected to the first conveyor shaft 12 via a coupling. The first motor is placed on a specially designed first motor mounting bracket, which is fixed on the first frame 14 to ensure that the motor is installed securely and facilitates maintenance and heat dissipation.

[0050] A weighing device 6 is installed on the first frame 11. The weighing device uses a high-precision electronic weighing sensor and is installed at a suitable position at the bottom of the frame. It can accurately measure the weight of the material in section a.

[0051] like Figure 3 , 6 As shown, the second frame 21 of section b warehouse 2 (intermediate section) is assembled from at least one small frame. The small frames are connected by bolts or other detachable connection methods, which makes it convenient to adjust the length of section b warehouse 2 according to the actual space and storage needs of the mine tunnel.

[0052] The second conveyor shaft 22 is installed on the second frame 21, and its number is determined according to the length and conveying capacity of section b silo 2, and it is evenly distributed on the frame.

[0053] The second baffle 23 is provided on both sides of the upper part of the second frame 22. Its structure and function are similar to the first baffle. It is detachable and easy to replace and maintain.

[0054] The intermediate motor is mounted on the second frame 21 and is connected to the second conveyor shaft 22 via chain or belt drive to drive the second conveyor shaft 22 to rotate. The number of intermediate motors can be set according to actual needs to ensure that materials can be smoothly transferred in section b silo 2.

[0055] like Figure 4 , 7 As shown, the third frame 31 of section c (output end) has a similar structure to the first frame and is used to install the third conveyor shaft 32. The third conveyor shaft 32 is mounted on the third frame 31 via bearings, and one end of it is connected to the second motor 33. The second motor 33 is placed on the second motor mounting bracket 34 on the third frame 31. The second motor mounting bracket 34 provides stable support for the motor and facilitates adjustment of the motor position.

[0056] The third frame 31 is equipped with third baffles 35 on both sides of the upper part to prevent material from overflowing during the output process.

[0057] The conveyor belts are connected and driven by the first conveyor shaft 12, the second conveyor shaft 22, and the third conveyor shaft 32. The conveyor belts are made of wear-resistant rubber, possessing good flexibility and friction, enabling efficient material transport. The first conveyor shaft 12 and / or the third conveyor shaft 32 serve as drive shafts; their rotation drives the conveyor belts. The first conveyor shaft and / or the second conveyor shaft 22 and / or the third conveyor shaft 32 rotate under the friction of the conveyor belts, achieving continuous material transfer from section a (bin 1) through section b (bin 2) to section c (bin 3).

[0058] like Figure 8 , 9 The d-section compartment 4 includes a fourth frame 41 and at least one pair of vertically staggered fourth conveyor shafts 42 disposed on the fourth frame 41, and a fourth baffle 43 is provided on each of the two sides of the upper part of the fourth frame 41.

[0059] The d-section compartment 4 can be located between the c-section compartment 3 and the b-section compartment 2;

[0060] Alternatively, the d-segment compartment 4 can be located between two adjacent b-segment compartments 2.

[0061] There are generally three types of driving methods, such as Figure 10 As shown:

[0062] The first type is an electrical control and monitoring system: the controller 5 controls the second motor 33, and the controller 5 can be a programmable logic controller (PLC).

[0063] The controller 5 controls the motor's start, stop, and speed adjustment according to a preset program. For example, when starting, it starts the second motor 33 and continuously adjusts the output frequency until the conveyor belt runs stably; when stopping, it stops the second motor 33.

[0064] The second type is an electrical control and monitoring system: controller 5 controls the second motor 33 and the first motor. Controller 5 can be a programmable logic controller (PLC).

[0065] The controller 5 controls the motor's start, stop, and speed adjustment according to a preset program. For example, when starting, it starts the second motor 33, then starts the first motor, and continuously adjusts the output frequency until the conveyor belt runs stably; when stopping, it stops the second motor 33 first, then stops the first motor, or they stop simultaneously.

[0066] The third type is an electrical control and monitoring system: the first motor, the second motor 33 and the intermediate motor are all connected to the controller, which can be a programmable logic controller (PLC).

[0067] The controller 5 controls the motor's start, stop, and speed adjustment according to a preset program. For example, during startup, the motors are started in a certain order, starting with the second motor 33. After the conveyor belt runs stably, the intermediate motor and the first motor are started according to the material transfer situation. During shutdown, the main drive second motor 33 is stopped first, and then the intermediate motor and the first motor are stopped in sequence to avoid material accumulation.

[0068] Based on the material weight signal measured by the weighing device 6, the controller 5 automatically adjusts the speeds of the first motor, the second motor 33, and the intermediate motor. When the material weight in section a silo 1 reaches a certain threshold, the speeds of the second motor 33 and / or the first motor are appropriately reduced to prevent the material from accumulating too quickly; when the material weight is below another threshold, the speeds of the second motor 33 and / or the first motor are increased to ensure material transfer efficiency.

[0069] The weighing device 6 is connected to the controller 5. The electronic weighing device converts the real-time measured weight signal into an electrical signal and transmits it to the controller 5.

[0070] The controller 5 processes and analyzes the weight signal, which is used to control the motor operation on the one hand, and to transmit the weight data to the host computer or display screen on the other hand, so that the operator can monitor the material storage status in section a warehouse 1 in real time.

[0071] Limit switch 7 is used for control. Limit switch 7 is installed on the first baffle 11 and / or the second baffle 21 and / or the third baffle 31. Limit switch 7 can be a proximity switch or a photoelectric switch.

[0072] like Figure 11 As shown, when the material accumulation height approaches or reaches the position of limit switch 7, limit switch 7 triggers a signal and transmits the signal to controller 5.

[0073] After receiving the signal from the limit switch 7, the controller 5 immediately controls the second motor 33 and / or the first motor to stop or reverse by a certain angle to prevent material from overflowing. At the same time, it issues an alarm signal to remind the operator to handle the situation.

[0074] Installation phase:

[0075] Determine a suitable horizontal position within the mine tunnel, and connect and fix the first frame 11, the second frame 21 (assembled from several smaller frames), and the third frame 31 in sequence, ensuring that the connection points are well sealed to prevent material leakage.

[0076] Install the first conveyor shaft 12 on the first frame 11, the second conveyor shaft 22 on the second frame 21, and the third conveyor shaft 32 on the third frame 31. Install the conveyor belt and ensure that the tension of the conveyor belt is appropriate, or adjust the tension of the conveyor belt by setting the d-section compartment 4.

[0077] A first motor and a first motor mounting bracket are installed on the first frame 11, and the first motor is connected to the first conveyor shaft 12. A second motor 33 and a second motor mounting bracket 34 are installed on the third frame 31, and the second motor 33 is connected to the third conveyor shaft 32. An intermediate motor is installed on the second frame 21 and connected to the second conveyor shaft 22.

[0078] A weighing device 6 is installed on the first frame 11, and limiters 7 are installed on the first baffle 11, the second baffle 21 and the third baffle 31.

[0079] The weighing device 6 and the limit switch 7 are connected to the controller 5 via a line. The controller 5 is then connected to the first motor, the second motor 33 and the intermediate motor to ensure normal signal transmission.

[0080] Operational phase

[0081] Material enters from the input end of section a silo 1 and falls onto the conveyor belt. The second motor 33 starts, driving the third conveyor shaft 32 to rotate. The conveyor belt starts running, transporting the material to section b silo.

[0082] When the material arrives at section b silo 2, the intermediate motor and the first motor start as needed to assist in the material transfer within section b silo 2, ensuring that the material is evenly distributed on the conveyor belt of section b silo 2.

[0083] As materials are continuously transferred, the weighing device 6 monitors the weight of materials in section a silo 1 in real time and transmits the signal to the controller 5. The controller 5 determines whether parameters such as the speed of the second motor 33 need to be adjusted according to the preset program.

[0084] When the material is transferred to section C, it will be output from section C.

[0085] During the material transfer process, the limit switch 7 monitors the material position in real time. If there is a risk of material overflow, the limit switch 7 sends a signal to the controller 5, which controls the corresponding motor to stop or adjust its speed to prevent material overflow.
