[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 4 This application provides a boiler ash hopper anti-bridging unloading device, including a base plate 1, a support leg 2 fixedly installed on the top of the base plate 1, a mounting frame 3 fixedly connected to one end of the support leg 2, an unloading box 4 fixedly installed on the inner side wall of the mounting frame 3, a boiler body 5 snapped onto the top of the unloading box 4, a discharge component 6 provided at the bottom of the unloading box 4, and a second discharge component 7 fixedly connected to the side wall of the support leg 2; the first discharge component 6 includes a rotating shaft 61 and a gear 62, the rotating shaft 61 is connected to the bottom of the unloading box 4 through a bearing, and the gear 62 is fixedly connected to the side wall of the rotating shaft 61. A circular block 63 is fixedly connected to the side wall of the unloading box 4, and a scraper 64 is fixedly connected to the side wall of the circular block 63. A discharge chute 65 is opened at the bottom of the unloading box 4. The discharge assembly 6 also includes a motor 66 and a gear 67. The motor 66 is fixedly installed at the bottom of the unloading box 4. The gear 67 is fixedly connected to the output end of the motor 66. The gear 67 is meshed with the gear 62. A positioning block 8 is fixedly connected to the side wall of the boiler body 5. The positioning block 8 is engaged with the unloading box 4. Bolts are threadedly connected to the side wall of the unloading box 4. The bolts are threadedly connected to the boiler body 5.

[0033] In this embodiment, the boiler body 5 is first started to discharge boiler ash into the unloading box 4. Then, the motor 66 is turned on to drive the gear 2 67 to rotate. Then, the gear 2 67 drives the gear 1 62 to rotate. Then, the gear 1 62 drives the circular block 63 to rotate through the rotating shaft 61. Then, the circular block 63 discharges the boiler ash through the scraper 64 using the discharge chute 65. The discharge is simple and convenient.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, a second discharge assembly 7 is fixedly connected to the side wall of the support leg 2. The second discharge assembly 7 includes a fixing frame 71 and a cylinder 72. The fixing frame 71 is fixedly connected to the side wall of the support leg 2, and the cylinder 72 is fixedly installed on one side of the fixing frame 71. A connecting plate 73 is fixedly connected to the output end of the cylinder 72. A rectangular box 74 is fixedly installed on one side of the connecting plate 73. The second discharge assembly 7 also includes a bottom cover 75, which is rotatably connected to the bottom of the rectangular box 74. The second discharge assembly 7 also includes a fixing plate 76 and a wheel 77. The fixing plate 76 is fixedly installed on the top of the base plate 1, and the wheel 77 is connected to the top of the fixing plate 76 through a bearing.

[0035] In this embodiment, opening the fixing frame 71 activates the cylinder 72, which in turn drives the connecting plate 73 to move. Then, the connecting plate 73, through the rectangular box 74, causes the bottom cover 75 to be squeezed by the wheel 77, allowing the rectangular box 74 to be positioned above the discharge chute 65 to discharge material. Then, starting the cylinder 72 can drive the rectangular box 74 to move through the connecting plate 73, allowing the rectangular box 74 to move the bottom cover 75 away from the wheel 77. Afterward, the bottom cover 75 will open under gravity to discharge the boiler ash inside the rectangular box 74, which is simple and convenient.

[0036] Working principle: First, starting the boiler body 5 can discharge boiler ash into the unloading box 4. Then, starting the motor 66 can drive gear 2 67 to rotate. Gear 2 67 will then drive gear 1 62 to rotate. Gear 1 62 will then drive the circular block 63 to rotate through the rotating shaft 61. Then, the circular block 63 will discharge the boiler ash through the scraper 64 and discharge it through the discharge chute 65. The discharge is simple and convenient.

[0037] Opening the fixing frame 71 activates the cylinder 72, which in turn moves the connecting plate 73. The connecting plate 73 then moves the bottom cover 75 through the rectangular box 74, which is then squeezed by the wheel 77. This allows the rectangular box 74 to be positioned above the discharge chute 65 to discharge material. Activating the cylinder 72 then moves the rectangular box 74 through the connecting plate 73, causing the bottom cover 75 to move away from the wheel 77. The bottom cover 75 then opens under gravity to discharge the boiler ash inside the rectangular box 74, making the discharge process simple and convenient.
