[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Example 1

[0028] Reference Figure 1 , Figure 2 , Figure 3 A ground storage and transportation device for coal mines includes: a main support 1, a transportation mechanism 2, and an adjusting support 3. The transportation mechanism 2 is installed on the main support 1, and the adjusting support 3 is installed at the bottom of the main support 1. The transportation mechanism 2 is used to transfer materials to the material storage area, and the adjusting support 3 is used to adjust the tilt angle of the main support 1.

[0029] In this embodiment, the adjusting bracket 3 includes two sub-brackets. One end of each sub-bracket is detachably connected to the main bracket 1, and the other end is connected to a fixed plane. The position and angle of the sub-brackets can be quickly changed or adjusted as needed. The detachable connection methods include bolt connections, pin connections, or quick-locking devices, ensuring the stability and reliability between the sub-brackets and the main bracket 1 during adjustment.

[0030] In this embodiment, one end of each of the two sub-supports is detachably connected to the main support 1, and the other ends of the two sub-supports are hinged to each other. The two sub-supports and the main support 1 form an inverted triangular structure, and the hinged ends of the two sub-supports are connected to a fixed plane. The inverted triangular structure not only provides sufficient stability to support the main support 1 and the transport mechanism 2 on it, but also allows the tilt angle of the main support 1 to be changed by adjusting the position of the hinge points. The connection between the hinged ends of the two sub-supports and the fixed plane can be fixed (e.g., fixed to a mounting base on the ground with bolts) or adjustable (e.g., fine-tuned by slide rails, adjusting bolts, etc.). The specific connection method chosen depends on the actual needs and conditions on site. When adjusting the adjusting bracket 3, the operator first needs to determine the required tilt angle of the main support 1 according to the actual needs and site conditions. Then, by loosening or tightening the connection devices between the sub-supports and the main support 1, and between the sub-supports and the fixed plane, the position and angle of the sub-supports are adjusted. Finally, the connection devices are re-locked to ensure the stability of the adjusting bracket 3 and the main support 1.

[0031] In this embodiment, the transport mechanism 2 includes a conveying component and a drive component 203. The conveying component is mounted on the main support 1, and the drive component 203 is connected to the conveying component. The conveying component and the drive component 203 together form a belt conveyor structure.

[0032] In this embodiment, the conveying assembly includes a conveyor belt, idlers, a support frame, a loading component, an unloading component, a guide component, a tensioning component, a cleaning component, and a lubricating component. The conveyor belt is made of a high-strength, wear-resistant, and tear-resistant material, such as rubber, polyester fiber, or nylon. Driven by the drive assembly, the conveyor belt runs at a certain speed and direction, transporting material from the loading point to the unloading point. Several idlers are evenly distributed along the conveyor belt's running path to ensure the conveyor belt remains stable and centered during operation. The idlers are mounted on the support frame, which is fixed to the main support frame 1, forming a stable support structure. The loading component is located at the beginning of the conveyor belt and is used to evenly place the material onto the conveyor belt. The unloading component is located at the end of the conveyor belt and is used to unload the material from the conveyor belt and send it to the material storage area. The guide component ensures that the conveyor belt does not deviate from the predetermined path during operation; the tensioning component adjusts the tension of the conveyor belt to compensate for the elongation or shortening of the conveyor belt caused by factors such as material weight and temperature changes. Cleaning components are used to remove residual materials and dust from the surface of the conveyor belt to prevent them from causing wear and blockage to the conveyor belt and idlers; lubrication components are used to provide an appropriate amount of lubricant between the conveyor belt and idlers to reduce friction and wear and extend the service life of the equipment.

[0033] This embodiment also includes an inspection component 4, which is installed on the side of the main support 1. The inspection component 4 is used by operators to inspect the transport mechanism 2. The inspection component 4 includes a stable inspection platform fixed to the side of the main support 1, providing operators with a safe and stable standing and working area. The design of the inspection platform should consider the safety and working needs of the operators, such as anti-slip and anti-fall measures, as well as sufficient working space. To ensure the safety of operators during the inspection process, guardrails and handrails are installed around the inspection platform. The guardrails prevent operators from accidentally falling, while the handrails facilitate movement and balance on the platform. Since the coal mining environment is usually dark, the inspection component 4 is also equipped with lighting equipment, such as LED lights or explosion-proof lights. These lighting devices provide sufficient light, allowing operators to clearly observe the operating status of the transport mechanism 2 and the surrounding environment.

[0034] In this embodiment, a control component is also included, and the transport mechanism 2 is connected to the control component; wherein, the control component is used to control the operating status of the transport mechanism 2. The operation of the transport mechanism 2 is controlled and monitored by the control component. The control component can receive signals from sensors, operators, or automatic control systems, and adjust the speed, direction, and operating status of the conveyor belt according to these signals. At the same time, the control component can also monitor the operating parameters of the transport mechanism, such as temperature, pressure, vibration, etc., as well as fault alarm and shutdown protection functions.

[0035] Example 2

[0036] Based on Embodiment 1, in this embodiment, a temporary storage component 201 is provided at the feed end of the transport mechanism 2; wherein, the temporary storage component 201 is used to temporarily store materials and guide the materials into the conveying component. The top and bottom openings of the temporary storage component 201 should be tightly connected to the corresponding material conveying equipment (such as underground hoisting equipment or conveying component) to ensure the continuity and stability of the materials during the transfer process. The connection method can be flange connection, bolt connection, or quick-locking device, depending on the actual needs and conditions on site. At the same time, the temporary storage component should be firmly fixed to the feed end of the transport mechanism 2 to prevent displacement or tipping during operation.

[0037] In this embodiment, the temporary storage component 201 is funnel-shaped, with openings at both the top and bottom. The bottom of the temporary storage component 201 corresponds to the feed end of the conveying component. The funnel-shaped design of the temporary storage component 201, with its larger top opening, facilitates the receipt of materials from underground or other sources. The bottom of the funnel gradually narrows, tightly connecting with the feed end of the conveying component to ensure smooth material flow into the conveyor belt. The temporary storage component 201 should be made of high-strength, wear-resistant, and tear-resistant materials, such as wear-resistant steel plates or special alloys, to resist material wear and impact, extending the service life of the temporary storage component. The capacity of the temporary storage component 201 is designed according to actual material transfer requirements, ensuring sufficient material storage for continuous operation of the conveying component while preventing excessive material accumulation that could lead to blockages or overflows. Furthermore, the material inflow speed and flow rate can be further controlled by adjusting the size of the funnel opening or by installing adjustable baffles.

[0038] In this embodiment, a flow monitoring component 202 is installed at the discharge end of the conveying mechanism 2; the flow monitoring component 202 is used to monitor the material flow rate at the discharge end in real time. The flow monitoring component 202 can be a solid flow meter. Solid flow meters suitable for the coal mine environment can be selected, such as impact flow meters, weighing flow meters, or volumetric flow meters. These flow meters should have good measurement accuracy, stability, and durability. The flow monitoring component 202 should be installed at the discharge end of the conveying mechanism 2 to ensure accurate measurement of the flow rate of material unloaded from the conveyor belt. During installation, it should be ensured that the solid flow meter is tightly connected to the end of the conveyor belt to avoid leakage or accumulation of material during the measurement process. Simultaneously, the installation angle and position of the solid flow meter should be considered to ensure accurate measurement of the material flow rate. The flow monitoring component 202 is equipped with a signal transmission device to transmit the measured material flow data to the control component or other related equipment in real time. Signal transmission can be wired or wireless, depending on the actual needs and conditions on site. Simultaneously, a data processing device is provided to process and analyze the received flow data to provide accurate material flow information. The flow monitoring component 202 also features alarm and protection functions. When the material flow exceeds the preset range or an abnormality occurs, it should automatically trigger the alarm device to alert operators to take timely measures. Simultaneously, it should have a shutdown protection function, automatically stopping the transport mechanism when the material flow is severely abnormal to prevent equipment damage or accidents.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
