[0010] Preferably, the openings of the steel plate and the wear-resistant lining plate are shortened from top to bottom. While the openings of the steel plate and the wear-resistant lining plate are shortened, the opening of the material retaining trough is also shortened from top to bottom. On the original basis, the inner side of the material retaining trough is horizontally shortened, from the original size of 1250 mm to 1000 mm.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: Embodiment

[0024] A cantilever tail material retaining device includes a bottom plate 1, and a material retaining device is arranged on the top of the bottom plate 1. The material retaining device includes a material retaining unit and a disassembly unit.

[0025] The material retaining unit is arranged at the left and right ends inside the bottom plate 1, and the disassembly unit is arranged on the front of the material retaining unit.

[0026] The material retaining unit includes rib plates 201, steel plates 202, wear-resistant lining plates 203 and a material retaining groove 204. The rib plates 201 are fixedly installed at the left and right ends inside the bottom plate 1. The number of steel plates 202 is two, and the two steel plates 202 are fixedly installed on the adjacent side of the left and right rib plates 201. The rib plates 201 and the steel plates 202 are made of 8mm manganese plates to provide support for the weight of the wear-resistant lining plate 203 and the load of the falling material impact. The wear-resistant lining plate 203 is installed on the side of the steel plate 202 away from the rib plate 201. The wear-resistant lining plate 203 is an 8 + 4 high-chromium composite plate to improve the wear resistance of the material retaining groove 204 body and reduce the maintenance frequency. The openings of the steel plate 202 and the wear-resistant lining plate 203 are shortened from top to bottom. At the same time as the openings of the steel plate 202 and the wear-resistant lining plate 203 are shortened, the opening of the material retaining groove 204 is shortened from top to bottom, and the inner side of the material retaining groove 204 is horizontally shortened on the original basis, from the original size of 1250mm to 1000mm. The lowest point of the lower opening body of the material retaining groove 204 is 30mm away from the belt after shortening. By reducing the opening size of the bolt 304, the falling point is adjusted so that the falling point is at the center position of the belt, enabling the stacker-reclaimer belt conveyor equipment to operate continuously and normally, reducing the deviation of the belt. The material retaining groove 204 is arranged between the left and right wear-resistant lining plates 203. Embodiment

[0027] On the basis of the first embodiment: The disassembly unit includes a dovetail block 301, a rotating shaft 302, a rotating block 303 and a bolt 304. The dovetail block 301 is fixedly installed on the side of the wear-resistant lining plate 203 close to the steel plate 202. A dovetail groove is provided on the surface of the steel plate 202 close to the wear-resistant lining plate 203. The dovetail block 301 is slidably connected in the dovetail groove. Through the cooperation of the dovetail block 301 and the dovetail groove, it is convenient to disassemble the wear-resistant lining plate 203. The rotating shaft 302 is fixedly installed on the front of the steel plate 202. One end of the rotating block 303 is rotatably connected to the outer surface of the rotating shaft 302. The bolt 304 is installed inside the other end of the rotating block 303. Threaded holes matching the bolt 304 are provided on the upper and lower sides of the front of the wear-resistant lining plate 203. The bolt 304 is threadedly connected inside the threaded hole. After the wear-resistant lining plate 203 is installed on the steel plate 202 through the dovetail block 301, by rotating the bolt 304 to cooperate with the threaded hole, the bolt 304 enters the wear-resistant lining plate 203, so as to fix the wear-resistant lining plate 203 on the steel plate 202.

[0028] During use, by modifying the opening of the material retaining groove 204 to make it smaller, the material falling during stacking and reclaiming of the equipment can fall on the center position of the belt conveyor. A wear-resistant lining plate 203 is installed on the inner side of the narrowed material retaining groove 204, so as to improve the wear resistance of the material retaining groove 204, so as to achieve the purpose that the belt conveyor does not deviate due to the falling position of the material. When the wear-resistant lining plate 203 is worn and needs to be replaced, by rotating the bolt 304, which is threadedly connected to the threaded hole provided on the wear-resistant lining plate 203, the bolt 304 is removed from the threaded hole provided on the wear-resistant lining plate 203, and then the rotating block 303 is rotated downward to prevent the rotating block 303 from blocking the disassembly of the wear-resistant lining plate 203. Then, the wear-resistant lining plate 203 is pushed outwards to remove the wear-resistant lining plate 203 from one side of the steel plate 202. Conversely, a new wear-resistant lining plate 203 can be installed, which is convenient for replacing the wear-resistant lining plate 203 and the operation is simple.
