[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments only are a part of the embodiments of the utility model, and not all the embodiments.

[0018] Embodiment: see Figures 1-4This utility model discloses a scraper conveyor for a fully mechanized mining face. Two rotating shafts 2 are symmetrically arranged at both ends of the frame 1, with drive wheels 4 fixedly connected to the sides of each shaft 2. Grooves 3 are provided on both sides of the frame 1. The frame 1 provides a supporting structure for the entire scraper conveyor, ensuring the stability of the equipment. The symmetrically arranged rotating shafts 2 and their drive wheels 4 provide the foundation for power transmission and the movement of the scraper 8. The grooves 3 guide and constrain the conveyed material, ensuring that the material does not scatter during conveying. A driven wheel 6 corresponding to the drive wheel 4 is rotatably arranged at the other end of the frame 1. A chain 7 is installed between the drive wheel 4 and the driven wheel 6. Multiple mounting plates 5 are equidistantly connected to the chain 7. A scraper is provided on one side of each mounting plate 5. 8. A fixing bolt is installed between the scraper 8 and the mounting plate 5. The driving wheel 4 drives the driven wheel 6 to rotate through the chain 7. The mounting plate 5 and scraper 8 on the chain 7 move accordingly. The scraper 8 can scrape the material for conveying, realizing continuous material transportation and improving material conveying efficiency. The fixing bolt ensures that the scraper 8 and the mounting plate 5 are firmly connected and that the scraper 8 can work normally. The replacement component includes a replacement plate 9. One side of the replacement plate 9 is provided with a rectangular groove corresponding to the inner shape of the trough side 3. The other side of the replacement plate 9 is provided with multiple fixing clamps 10. The rectangular groove on one side of the replacement plate 9 is adapted to the inner shape of the trough side 3, which facilitates accurate positioning and replacement of the trough side 3. The multiple fixing clamps 10 provide a structural foundation for subsequent fixing of the trough side 3, making the replacement operation of the trough side 3 more convenient and faster.

[0019] In this utility model, the fixing clamp 10 abuts against the outer side of the groove side 3. Multiple fixing bolts are passed between the fixing clamp 10 and the replacement plate 9. The fixing clamp 10 abuts against the outer side of the groove side 3 and is connected to the replacement plate 9 through the fixing bolts, which can firmly fix the groove side 3, ensure the stability of the groove side 3 during use, extend the service life of the groove side 3, and facilitate the replacement of damaged groove side 3. Multiple locking grooves 12 are equidistantly opened on the opposite surfaces of the drive wheel 4 and the driven wheel 6. The locking grooves 12 on the drive wheel 4 and the driven wheel 6 can better lock and position the chain 7, prevent the chain 7 from slipping or falling off during operation, improve the stability of the chain 7, and ensure the normal operation of the scraper conveyor 8. One end of the rotating shaft 2 is coaxially fixed to a drive motor 11 installed on one side of the outer wall of the frame 1. The drive motor 11 is coaxially fixed to the rotating shaft 2, which can efficiently transmit power to the rotating shaft 2, thereby driving the drive wheel 4 to rotate, providing stable and reliable power for the scraper conveyor 8, improving power transmission efficiency, and ensuring the stable operation of the scraper conveyor 8.

[0020] Working principle: when the utility model uses, when need to install replacement plate 9 to groove help 3, first scraping plate 8 conveyor stops and ensures to be in safe state, because the one side of replacement plate 9 is equipped with the rectangular groove matching with the shape of the inside of groove help 3, this makes replacement plate 9 can accurately adhere to the inside of groove help 3, the rectangular groove of replacement plate 9 is aligned with the inside of groove help 3, slowly pushes replacement plate 9, makes it closely with the inside contact of groove help 3, at this moment, the multiple fixed clamping plates 10 of the other side of replacement plate 9 are placed in the outside of groove help 3 correspondingly, then, using fixed bolt sequentially passes through the fixed clamping plate 10 and replacement plate 9 on the preset bolt hole, and tightens these fixed bolts, along with the tightening of fixed bolt, fixed clamping plate 10 will tightly abut on the outside of groove help 3, through the joint action of fixed clamping plate 10 and replacement plate 9, groove help 3 is firmly clamped in the middle, completes the installation of replacement plate 9 on groove help 3, after installation, check whether fixed bolt is tightened, and the adhesion condition of replacement plate 9 and groove help 3, ensure that installation is firm and has no loosening.

[0021] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art in the technical range disclosed by the utility model, according to the technical scheme and utility model concept of the utility model, equivalent replacement or change, should be covered in the protection scope of the utility model.
