[0027] See also Figure 1-5 A grate side transmission device includes a column frame 1, one side end of the column frame 1 is fixedly connected to a unit shell 2, a plurality of hydraulic cylinders 3 are arranged in the column frame 1, a plurality of flip tile couplings 4 are rotatably connected in the unit shell 2, and the two ends of the plurality of flip tile couplings 4 respectively pass through the two sides of the unit shell 2, the circumferential surfaces of the plurality of flip tile couplings 4 are detachably connected with rocker arms 5, and the plurality of rocker arms 5 respectively correspond to the output ends of the plurality of hydraulic cylinders 3, and the plurality of rocker arms 5 are respectively provided with hinge holes 6, and the output ends of the plurality of hydraulic cylinders 3 are respectively provided with hinge components 7, and the plurality of hinge components 7 are respectively matched with the plurality of hinge holes 6.
[0028] In this embodiment, the tail ends of multiple hydraulic cylinders 3 are installed in the column frame 1 in a hinged manner, and the output ends of the multiple hydraulic cylinders 3 are respectively hinged to the multiple rocker arms 5 through multiple hinge holes 6 and multiple hinge assemblies 7. The grate plates are installed on the movable grate frame on one side of the unit shell 2, and the movable grate frame is connected to one end of multiple flip tile connecting shafts 4. The multiple hydraulic cylinders 3 are telescopically controlled in the column frame 1 to swing the multiple rocker arms 5, so that the rotation of the multiple flip tile connecting shafts 4 is transmitted to the combustion section of the movable grate frame. The grate plates are controlled by the movable grate frame to perform reciprocating motion, and the combustion materials move downward step by step through the grate plates, thereby achieving the effect of burning, discharging and unloading ash at the same time.
[0029] Specifically, each hinge assembly 7 includes an outer tube 71, an inner tube 72, a spring 73 and two rotating shafts 74. The outer tube 71 is slidably connected to the output end of the hydraulic cylinder 3, the inner tube 72 is slidably inserted into the outer tube 71, the spring 73 is arranged in the outer tube 71 and the inner tube 72, and the two rotating shafts 74 are respectively fixedly connected to the ends of the outer tube 71 and the inner tube 72 away from each other, and the two rotating shafts 74 match a hinge hole 6.
[0030] In this embodiment, the two rotating shafts 74 enter the hinge hole 6 under the action of the elastic force of the spring 73, so that the output end of the hydraulic cylinder 3 is hinged to the rocker arm 5, thereby pushing the rocker arm 5 to rotate the tile-turning connecting shaft 4, thereby driving the grate. When the hydraulic cylinder 3 needs to be disassembled and assembled, by pressing the two rotating shafts 74, the outer tube 71 and the inner tube 72 are plugged into each other to squeeze the spring 73, and the two rotating shafts 74 are moved out of the hinge hole 6 to disassemble and assemble the hydraulic cylinder 3.
[0031] Specifically, one end of the outer tube 71 is fixedly connected to a first limiting plate 8 , and the first limiting plate 8 corresponds to the output end of a hydraulic cylinder 3 , and one end of the inner tube 72 is fixedly connected to a second limiting plate 9 , and the second limiting plate 9 is slidably connected to the outer tube 71 .
[0032] In this embodiment, the first limiting piece 8 limits the outer tube 71 to prevent the outer tube 71 from falling at the output end of the hydraulic cylinder 3 , and the second limiting piece 9 limits the inner tube 72 to prevent the inner tube 72 from falling from the outer tube 71 .
[0033] Specifically, one end of each of the plurality of hydraulic cylinders 3 is movably hinged to a hinge seat 10 via a hinge shaft, and each of the plurality of hinge seats 10 can be detachably connected to the column frame 1 , and each of the plurality of hinge seats 10 is provided with a mounting hole 11 .
[0034] In this embodiment, the hinge seat 10 is installed in the column frame 1, so that the tail end of the hydraulic cylinder 3 is hingedly installed in the column frame 1, and the hinge seat 10 is installed and fixed with bolts through the installation hole 11.

[0036] In this embodiment, the stuffing box 12 is a shaft sealing device of the flap coupling 4, which has a good sealing effect and prevents impurities and smoke caused by combustion materials from floating out of the connection between the unit shell 2 and the flap coupling 4. The bearing seat 13 assists the rotation of the flap coupling 4, so that the rotation of the flap coupling 4 remains stable and smooth.
[0037] Working principle: the tail ends of multiple hydraulic cylinders 3 are mounted in the column frame 1 in a hinged manner, and every two rotating shafts 74 enter a hinge hole 6 under the action of the elastic force of a spring 73, so that the output ends of the multiple hydraulic cylinders 3 are respectively hinged to the multiple rocker arms 5, and the grate pieces are mounted on the movable grate frame on one side of the unit shell 2. The movable grate frame is connected to one end of multiple flip tile couplings 4. Multiple hydraulic cylinders 3 are telescopically controlled in the column frame 1 to swing the multiple rocker arms 5, so that the rotation of the multiple flip tile couplings 4 is transmitted to the combustion section of the movable grate frame. The grate pieces are controlled by the movable grate frame to perform reciprocating motion, and the combustion materials move downward step by step through the grate pieces, thereby achieving the effect of burning, discharging and unloading ash at the same time. When the hydraulic cylinder 3 needs to be dismantled, by pressing the two rotating shafts 74, the outer tube 71 and the inner tube 72 are plugged into each other to squeeze the spring 73, and the two rotating shafts 74 are moved out of the hinge hole 6, so that the hydraulic cylinder 3 can quickly detach from the rocker arm 5 for disassembly.
