Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0020] like Figures 1 to 4 As shown, a scraper conveyor protection device includes a body 2, the body 2 includes a feed pipe 21, a conveying rod 31, a transmission chain 32 and a plurality of material scrapers 33 arranged on the transmission chain 32, the feed pipe 21 is installed on the upper side of the body 2;
[0021] The top of the body 2 is provided with a mounting base 22, and the mounting base 22 is provided with a first drive motor 23. The output shaft of the first drive motor 23 is connected to a first transmission wheel 24, and the first transmission wheel 24 is connected to a transmission belt 25, and the transmission belt 25 is connected to a second transmission wheel 26, and the second transmission wheel 26 is connected to a conveying rod 31. The conveying rod 31 is connected to a transmission chain 32 for driving the transmission chain 32 to move; the first drive motor 23 drives the conveying rod 31 to rotate, thereby driving the transmission chain 32 to move, which is conducive to automatic material transportation and has a high degree of mechanization.
[0022] Material scrapers 33 are installed on both sides of the transmission chain 32, and a roller assembly is installed on the side of the material scraper 33 close to the inner wall of the body 2. An annular groove 41 is opened on the inner wall of the body 2, and an annular guide rail 42 is provided in the annular groove 41. Each roller assembly is rolled in the annular guide rail 42.
