[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a hopper sealing door device suitable for a waste incinerator, comprising a furnace top 4, a base mechanism 2 is arranged near the middle position of the top of the furnace top 4, a hopper mechanism 1 is arranged on the top of the base mechanism 2, a power mechanism 3 is symmetrically arranged at the position of the top of the furnace top 4 near the base mechanism 2, the base mechanism 2 comprises a hopper base 201, the hopper base 201 is fixedly connected to the top of the furnace top 4, the front and rear inner walls of the hopper base 201 are fixedly connected to the right side with a mounting seat 202, bearings 203 are embedded in the interior of the mounting seat 202, a mounting shaft 204 is fixedly connected between the inner walls of the two bearings 203, the outer surface of the mounting shaft 204 slides through the outer surface of the hopper base 201, and the outer surface of the mounting shaft 204 A sealing plate 205 is connected to the middle of the surface, the hopper mechanism 1 includes a feed hopper 101, and the feed hopper 101 is fixedly connected to the top of the hopper base 201. The two power mechanisms 3 include a first connecting member 301, and the two first connecting members 301 are symmetrically fixedly connected to the top of the furnace top 4 near the right side. A second rotating member 306 is rotatably connected between the inner surface walls of the first connecting member 301, and a cylinder 302 is installed on the left surface of the second rotating member 306. The left end of the cylinder 302 is fixedly connected to the first rotating member 303, and the rear surface of the first rotating member 303 is rotatably connected to a rotating shaft 304, and the rear end of the rotating shaft 304 is fixedly connected to a connecting rod 305, and the connecting rod 305 is connected to the end of the mounting shaft 204 near the top.

[0023] The effect achieved by the entire embodiment 1 is that when it is necessary to open the feed hopper 101 to put in garbage, the oil cylinder 302 is started to retract it. At this time, the second rotating member 306 on the tail end of the oil cylinder 302 will rotate upward inside the first connecting member 301, and the first rotating member 303 at the telescopic end of the oil cylinder 302 will pull the lower end of the connecting rod 305 to move to the right through the rotating shaft 304. At this time, the connecting rod 305 will rotate with the installation shaft 204 as the center of the circle, and will drive the installation shaft 204 to rotate in the opposite direction. When the installation shaft 204 rotates in the opposite direction, it will drive the sealing plate 205 inside the hopper base 201 to flip downward, so that the feed hopper 101 and the garbage incinerator are connected. The furnace top 4 forms a connected state. When the feed hopper 101 needs to be closed, the oil cylinder 302 is started to extend to drive the sealing plate 205 to rotate to a horizontal state, thereby closing the internal space of the hopper base 201. The device mainly uses the movement of the oil cylinder 302 to drive the connecting rod 305 to rotate. After the connecting rod 305 rotates, it cooperates with the installation shaft 204 to control the sealing plate 205 used to open and close the feed hopper 101 to rotate, thereby realizing the opening and closing of the hopper sealing door of the waste incinerator. The use effect is high, which solves the problems existing in the existing hopper sealing doors on the market, thereby improving the operating efficiency of the waste incinerator. At the same time, it also provides a more convenient way for later maintenance.

[0024] Embodiment 2, as Figure 1-Figure 4As shown, a rotating seat 102 is symmetrically fixedly connected to the right surface of the feed hopper 101 near the top, a connecting seat 103 is rotatably connected between the outer surfaces of the two rotating seats 102, a sealing cover 104 is fixedly connected to the outer surface of the connecting seat 103, partitions 105 are fixedly connected to the inner walls on both sides of the feed hopper 101 near the bottom, and the top of the furnace top 4 is symmetrically fixedly connected to the limiting block 41 at the front and rear sides of the hopper base 201, and the right surface of the limiting block 41 conflicts with the left surface of the connecting rod 305.

[0025] The effect achieved by the entire embodiment 2 is that, when the waste incinerator is out of use, the sealing cover 104 can be rotated upward under the action of the rotating seat 102 and the connecting seat 103, so that it can be placed on the top of the feed hopper 101 to play a protective role. At the same time, when the connecting rod 305 rotates to a vertical state and drives the sealing plate 205 to rotate, the connecting rod 305 will be blocked by the limit block 41 and cannot move forward, thereby ensuring the horizontal state of the sealing plate 205. The structure is simple and the sealing effect of the sealing plate 205 is ensured. The partition 105 is mainly used to guide the input garbage and fill the gap between the sealing plate 205 and the inner wall of the hopper base 201.

[0026] Working principle: when it is necessary to open the feed hopper 101 to put in garbage, the oil cylinder 302 is started to retract it. At this time, the second rotating member 306 on the tail end of the oil cylinder 302 will rotate upward inside the first connecting member 301, and the first rotating member 303 at the telescopic end of the oil cylinder 302 will pull the lower end of the connecting rod 305 to move to the right through the rotating shaft 304. At this time, the connecting rod 305 will rotate with the installation shaft 204 as the center of the circle, and will drive the installation shaft 204 to rotate in the opposite direction. When the installation shaft 204 rotates in the opposite direction, it will drive the sealing plate 205 inside the hopper base 201 to flip downward, so that the feed hopper 101 and the top 4 of the garbage incinerator are connected. When it is necessary to close the feed hopper 101, the oil cylinder 302 is started to extend to drive the sealing plate 205 to rotate to a horizontal state, thereby closing the internal space of the hopper base 201. This device mainly uses the oil cylinder 302 The movement drives the connecting rod 305 to rotate. After the connecting rod 305 rotates, it cooperates with the installation shaft 204 to control the sealing plate 205 used to open and close the feed hopper 101 to rotate, thereby realizing the opening and closing of the hopper sealing door of the garbage incinerator. The use effect is high, which solves the problems existing in the existing hopper sealing doors on the market, thereby improving the operating efficiency of the garbage incinerator. At the same time, it also provides a more convenient way for later maintenance. When the garbage incinerator is out of use, the sealing cover 104 can be rotated upward under the action of the rotating seat 102 and the connecting seat 103, so that it can be placed on the top of the feed hopper 101 to play a protective role. At the same time, when the connecting rod 305 rotates to a vertical state and drives the sealing plate 205 to rotate, the connecting rod 305 will be blocked by the limit block 41 and cannot move forward, thereby ensuring the horizontal state of the sealing plate 205. The structure is simple and ensures that the sealing effect of the sealing plate 205 is improved.
