When the feeding cart 20 (see fig. 1) is pushed to the movable block 29, the bottom edge of the feeding cart 20 presses down the end of the movable block 29 close to the drying kiln 1, so that the end of the movable block 29 far from the drying kiln 1 is lifted to abut against the bottom edge of the feeding cart 20, at this time, the hydraulic cylinder 28 is driven, the piston in the hydraulic cylinder 28 extends out, and thus the end of the movable block 29 far from the drying kiln 1 gives a force to the feeding cart 20, so that the feeding cart 20 is forced to slide towards the drying kiln 1.

As shown in fig. 3, the skid device 3 includes a motor 32 and a third slide rail 31. The third slide rail 31 is slidably connected into the tail end of the second slide rail 212, a connecting rod 33 parallel to the width direction of the third slide rail 31 is fixedly connected into the third slide rail 31, and the connecting rod 33 extends out of the third slide rail 31. A threaded rod 34 is fixedly connected to an output shaft of the motor 32, and the threaded rod 34 penetrates through a connecting rod 33 extending to the outer side of the third sliding rail 31 and is in threaded connection with the connecting rod 33. When the plurality of feeding carts 20 (see fig. 1) are slidably connected to the first sliding rail 211 (see fig. 1), the motor 32 is started, the motor 32 drives the threaded rod 34 to rotate, so that the connecting rod 33 in threaded connection with the threaded rod 34 drives the third sliding rail 31 to slide towards the direction close to the drying kiln 1 until the third sliding rail 31 abuts against the first sliding rail 211, and the sliding rail 21 is in a closed ring shape, so that the feeding carts 20 can circularly feed materials from the first sliding rail 211 to the second sliding rail 212 and then from the second sliding rail 212 to the first sliding rail 211 through the third sliding rail 31, and the feeding efficiency is improved.

Meanwhile, the sliding plate 4 is placed on the first sliding rail 211 until the first sliding rail 31 abuts against the second sliding rail 211, and at the moment, the first sliding rail 211, the second sliding rail 212 and the third sliding rail 31 form a closed annular guide rail 35. The bottom surface of the feeding car 20 presses down the end of the movable block 29 at the first slide rail 211 close to the drying kiln 1, so that the end far away from the drying kiln 1 is lifted to abut against the bottom edge of the feeding car 20. The hydraulic cylinder 28 is driven, so that the piston in the hydraulic cylinder 28 moves, when the piston moves to the inlet of the drying kiln 1, one end of the movable block 29, which is far away from the drying kiln 1, pushes the feed carriage 20 to slide, and the catalyst on the feed carriage 20 slides to the tail end of the first sliding rail 211 after being dried by the drying kiln 1. After the dried catalyst is unloaded, the feeding cart 20 is pushed to the second slide rail 212, the un-dried catalyst is loaded, the feeding cart 20 is pushed to press down the end, close to the drying kiln 1, of the movable block 29, and the end, far away from the drying kiln 1, of the movable block 29 is lifted to be abutted against the bottom edge of the feeding cart 20. The hydraulic cylinder 28 is driven so that the piston in the hydraulic cylinder 28 moves to the entrance of the drying kiln 1, and the movable block 29 is driven by the end far away from the drying kiln 1 to slide the feeding cart 20. After the catalyst on the feeding car 20 is dried by the drying kiln 1, the catalyst slides to the tail end of the second slide rail 212, after the dried catalyst is unloaded, the feeding car 20 is pushed to the first slide rail 211, and the catalyst which is not dried is loaded, so that the feeding car 20 can feed continuously and circularly, and the working efficiency is improved.
