[0002] In open-pit coal mining operations involving isolated coal pillars, the surface of the mining area is prone to problems such as soil structure damage and vegetation loss, which urgently require ecological protection and restoration through soil turning and sowing.

[0003] Existing soil turning equipment is unstable and uneven in turning depth when operating in complex coal mining sites, making it difficult to provide good soil conditions for seed growth; while seeding equipment often suffers from seed clogging and uneven sowing, further reducing the effectiveness of seed protection. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated mining device for isolated coal pillars in open-pit coal mines, which has the advantages of being able to evenly turn over and sow soil, and efficiently protect the surface of the mining area.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an integrated mining device for isolated coal pillars in open-pit coal mines, comprising a movable plate, a tracked wheel fixedly connected to the bottom of the movable plate, a control box fixedly connected to the left side of the top of the movable plate, a rotary tiller box movably installed on the right side of the movable plate, a rotary tiller component movably connected inside the rotary tiller box, a drive motor fixedly connected to the front and rear sides of the top of the rotary tiller box, and pulleys fixedly connected to the output end of the drive motor and the front and rear sides of the rotary tiller component, with a transmission belt sleeved on the surface of the pulleys; The top of the movable plate is fixedly connected to a mining and repair mechanism, which includes a material spreading pipe fixedly connected to the right side of the bottom of the movable plate.

[0006] The above technical solution is adopted to adapt to the scenario of mining coal pillars on isolated islands by setting up tracked wheels. The motor drives the rotary tiller through pulleys and transmission belts to realize the mining of coal pillars. The material spreading pipe of the mining and repair mechanism can simultaneously carry out site repair, achieving the integration of mining and repair and improving the continuity of operation.

[0007] The present invention is further configured such that the mining and repair mechanism also includes a material supply box, which is fixedly connected to the right side of the top of the moving plate. The right side of the material supply box is connected to a conveying pipe assembly, and the other side of the conveying pipe assembly extends into the interior of the spreading pipe.

[0008] The above technical solution is adopted: through the setting of the mining and repair mechanism, the conveying pipe group stably conveys the material to the spreading pipe, ensuring the continuity of the repair material supply. This structure makes the material conveying path clear, reduces leakage and loss during the material conveying process, ensures uniform and efficient repair operations, and is suitable for the immediate repair needs after mining.

[0009] The present invention is further configured such that a vibrating plate is provided inside the feeding box, and a transmission rod is fixedly connected to each of the four corners of the bottom of the vibrating plate, with the bottom of the transmission rod extending through to the bottom of the feeding box.

[0010] The above technical solution avoids material accumulation and blockage by setting up a vibrating plate, ensuring smooth material falling. The transmission rod connects to the vibrating plate and extends to the bottom of the feeding box, providing a foundation for the subsequent installation of the drive structure, ensuring stable transmission of vibration driving force, improving feeding stability, and reducing feeding failures.

[0011] The present invention is further configured such that a mounting plate is fixedly connected to the bottom of the transmission rod, and a vibration motor is fixedly connected to the bottom of the mounting plate.

[0012] The above technical solution is adopted: by setting the mounting plate, the connection stability between the vibration motor and the transmission rod can be enhanced, avoiding loosening of the connection during vibration and ensuring continuous and normal material supply from the feeding box.

[0014] By adopting the above technical solution, the vibration effect of the vibrating plate can be improved by setting the auxiliary vibration spring, while buffering the impact force generated when the vibration motor is working, reducing the damage to the bottom of the feeding box, extending the service life of the device, reducing noise during vibration, and improving the working environment.

[0015] The present invention is further configured such that a protective cover is fixedly connected to the top of the rotary tiller box, and the drive motor is located inside the protective cover.

[0016] The above technical solution is adopted to prevent dust, gravel and other debris generated during open-pit coal mining from contacting the motor, thus avoiding damage to the motor. At the same time, it can prevent external environmental interference with the motor operation, ensure the stable driving of the rotary tiller by the motor, and reduce the probability of equipment failure.

[0017] The present invention is further configured such that a cover plate is movably connected to the top of the feeding box, and the cover plate is located on top of the movable plate.

[0018] The above technical solution is adopted as follows: By setting a transparent plate, the repair material can be easily added by opening the cover, and when closed, it can prevent dust and other debris from entering the material supply box and contaminating the material. The cover structure is simple and easy to operate, which improves the convenience of using the material supply box, while ensuring the purity of the material and ensuring the repair effect.

[0019] The present invention is further configured such that a transparent plate is fixedly connected to the front side of the feeding box, and the transparent plate is located in front of the vibrating plate.

[0020] The above technical solution allows operators to visually observe the remaining material in the feeding box and replenish it in a timely manner, avoiding disruption to repair work due to insufficient material. The transparent panel is easy to install, does not affect the overall structural stability of the feeding box, and improves the ease of use of the device.

[0021] In summary, this utility model has the following beneficial effects: 1. This utility model, through the installation of tracked wheels, is adapted to the scenario of mining coal pillars on isolated islands. The motor drives the rotary tiller through pulleys and transmission belts to achieve coal pillar mining, while the material spreading pipe of the mining and repair mechanism can simultaneously carry out site repair, achieving integrated mining and repair and improving the continuity of operations; 2. This utility model facilitates the inspection and replacement of rotary tillage components through the design of the rotary tillage box and the movable plate.
