4) after more carbonized garbage is accumulated in the shell 53, the V-shaped plate 56 is pulled, so that the garbage in the shell 53 falls into the ash discharge groove 51 for cleaning.

The working principle of the invention is as follows: when the invention is used, the hinged garbage is poured into the feeding barrel 3, then the shaft 15 is driven to rotate by the motor 14, the shaft 15 drives the fixed rod 111 and the connecting rod II 114 to rotate, and further drives the carbonization barrel 21 and the rotating plate 112 to rotate, so that the carbonization barrel 21 moves to the position shown in figure 1, at the moment, the transmission block 219 is jacked up by the spring II 221, and the transmission block 219 moves to the feeding port II 218, after passing through the feeding port II 218, the transmission block 219 jacks up the supporting rod 43, the supporting rod 43 drives the movable plate I42 to move upwards, the movable plate I42 drives the transmission rod III 49 to move upwards, the transmission rod III 49 drives one end of the transmission rod II 46 to move upwards, the other end of the transmission rod II 46 to move downwards, the transmission rod I45 drives the movable plate II 44 to move downwards, so that a gap is leaked between the movable plate II 44 and the vertical end of the L-shaped baffle plate 41, and the garbage falls into an outlet feeding port I16 of the feeding barrel 3, then the garbage leaks out from the feeding hole I16 through a gap between the vertical end of the L-shaped baffle plate 41 and the feeding hole I16 and a gap between the movable plate II 44 and the L-shaped baffle plate 41, and falls into the carbonization cylinder 21 through the feeding hole II 218 under the action of gravity, when the volume of the garbage falling into the carbonization cylinder 21 is enough, the motor 14 is started, the motor 14 drives the shaft 15 to rotate, and further drives the carbonization cylinder 21, the rotating plate 112, the electric heating tube I22 and the electric heating tube II 25 to rotate through the fixed rod 111 and the connecting rod II 114, and in the rotating process, because the length of the connecting rod I19 is fixed, the carbonization cylinder 21 pushes the connecting rod I19, the T-shaped sliding block 18 and the

circular rings

215 and 217 connected to the lower end of the connecting rod I19 to move, the circular rings 215 and the circular plates 217 push the garbage entering the carbonization cylinder 21 to move, in the moving process of the circular rings 215, the driving block 219 moves into the groove 220 after being separated from the feeding hole II 218, and the circular rings 215 move relative to the carbonization cylinder 21, therefore, the circular plate 217 at the center of the circular ring 215 slides in the spiral groove on the electric heating tube II 25 through the limiting block, so that the circular plate 217 and the circular ring 215 are driven to rotate relatively, the circular plate 217 drives the elastic telescopic rod 216 on the side surface of the circular plate to rotate, and the garbage can be stirred through the elastic telescopic rod 216 in the process of pushing the garbage to move, so that the positions of the garbage are exchanged, and the situation that the garbage is not completely carbonized is avoided;

after the carbonization of the garbage is completed, the circular ring 215 and the circular plate 217 push the garbage to move to the other end of the carbonization cylinder 21, at this time, the circular ring 215 and the circular plate 217 push the garbage, and when the garbage passes through the discharge port 210, the garbage directly leaks out of the carbonization cylinder 21 through the discharge port 210 and falls onto the inclined plate 54; when all the garbage is separated from the discharge port 210, the circular ring 215 and the circular plate 217 continue to move, the sliding plate II 211 is in contact with the sliding plate I29, the sliding plate II 211 slides in the opposite direction of the movement of the circular ring 215 and the circular plate 217 until the clamping block 212 is clamped into the clamping groove, then the circular ring 215 and the circular plate 217 continue to move, the sliding plate II 211 pushes the sliding plate I29 to slide outwards and compress the spring I27 until the circular ring 215 and the circular plate 217 abut against the inner wall of the carbonization cylinder 21, at the moment, the sliding plate II 211 blocks the discharge port 210 below to prevent the garbage from directly falling out after entering from the feed port II 218, and simultaneously, when the circular ring 215 and the circular plate 217 abut against the inner wall of the carbonization cylinder 21, the transmission block 219 pops up again, so that the garbage in the feed cylinder 3 enters the carbonization cylinder 21 through the other outlet, then the motor 14 is reversely started, and carbonization is performed again; the carbonization cylinder 21 adopts a spiral shape, so that the required occupied area is small compared with linear garbage conveying, and the factory building cost can be effectively reduced;

when the waste ash drops to the swash plate 54 from the carbonization cylinder 21, drop to the V-shaped plate 56 through the ash discharge port 55 along the swash plate 54, then drop to the inner wall end that is close to the casing 53 along the inclined plane of V-shaped plate 56, through the setting on two inclined planes, effectively less waste ash flies upward, when the waste ash is piled up too much, pulling V-shaped plate 56, make the waste ash drop to in the ash discharge groove 51, then moving V-shaped plate 56 to the normal position, it can to promote the ash discharge groove 51 and clear up the waste ash, do not influence equipment work.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
