Description

TECHNICAL FIELD

[0002] At present, in the process of treating household garbage, it is mostly incinerated by an incinerator. The material is heated, dried and burned in the incinerator. In the process of garbage combustion treatment, the garbage is first sent into the feeding device by the garbage grab bucket, and then sent from the feeding device to the incinerator for incineration. The feeding device generally includes a hopper, a chute passage and a feeder. The lower end of the hopper is connected with the chute passage, and the feeder is located below the chute passage and communicates with the incinerator. The garbage is grabbed into the hopper and falls into the chute passage, and then falls from the chute passage to the feeder, and finally is transported from the feeder into the incinerator.

The driver drives the broken bridge plate to rotate through the extension belt. A telescopic sleeve is fixed at one end of the outer periphery of the driver and at the other end of the outer wall of the hopper chute around the through hole to seal the gap between the driver and the through hole. In the process of driving the broken bridge plate to rotate through the extension belt, the broken bridge plate does not rub against the telescopic sleeve, thereby prolonging the service life on the basis of effectively sealing the through hole.

[0004] According to the related technology in the above, the connection between the hopper and the chute passage may be bridged due to high humidity of the garbage, unblended garbage, high material level or too compact garbage, etc., resulting in the lower end of the hopper being blocked. Therefore, some bridge breaking devices are needed to clean and dredge.

[0039] The opening 6 is located at the higher side of the chute channel 2, when the broken bridge plate 41 is in the initial state, the broken bridge plate 41 just covers the opening 6 and is attached to the side wall of the chute channel 2 where the opening 6 is located, and the plug rod 51 is completely located below the lower surface of the broken bridge plate 41 and one end is located within the thickness of the broken bridge plate 41, at this time, the broken bridge plate 41 and the plug rod 51 will not affect the normal falling of garbage in the chute channel 2; when the broken bridge plate 41 is turned upward, the broken bridge plate 41 can enter the hopper 1.

[0043] When the insertion rod 51 rotates, since the insertion rod 51 is threadedly connected with the broken bridge plate 41, the insertion rod 51 can move along the length direction of the insertion rod 51 and be better inserted into the inside of the garbage; and when the insertion rod 51 moves, the power piece 52 can synchronously slide with the sliding block 8, so as to ensure the stable transmission connection between the power piece 52 and the insertion rod 51. And the first rod 511 and the second rod 512 can be inserted into the jammed garbage from different directions, so as to more comprehensively pull the jammed garbage downward, and improve the reliability of cleaning and dredging.

[0044] In some embodiments, a vibration motor 9 is mounted on the lower surface of the broken bridge plate 41. When the insertion rod 51 is inserted into the inside of the jammed garbage, the vibration motor 9 can drive the broken bridge plate 41 and the insertion rod 51 to vibrate, so as to loosen the jammed garbage, and make the garbage fall down better.

When the moving part 412 slides, the moving part 412 always blocks the through hole 10, and the cavities 12 can limit the stable sliding of the moving part 412 and ensure that the through hole 10 is blocked. A connecting block 14 is fixed on the lower surface of the moving part 412 near the center, the fixed part 411 is rotatably connected with a screw rod 13, the screw rod 13 is parallel to the lower surface of the fixed part 411 and is relatively stationary, the screw rod 13 penetrates through the connecting block 14 and is threadedly connected with the connecting block 14, the screw rod 13 is arranged along the sliding direction of the moving part 412, and the adjusting piece 11 is a second motor in transmission connection with the screw rod 13.

The maintenance door 16 can facilitate the opening of the cover 15 to maintain the bridge breaking component 4.

[0048] The feeder 3 includes a housing 31, a pusher block 32, and a hydraulic cylinder 33. The upper side of the housing 31 is connected to the lower end of the chute channel 2. The pusher block 32 is attached to and slidably connected to the lower side of the interior of the housing 31. The pusher block 32 slides along the direction of entering and exiting the interior of the housing 31. The hydraulic cylinder 33 is installed outside the housing 31 and is used to drive the pusher block 32 to slide. The reciprocating pusher block 32 can push the garbage that falls to the bottom of the housing 31 into the incinerator.

[0049] The implementation principle of the waste incinerator feeding device in this application embodiment is as follows: When a blockage occurs at the connection between the lower end of the hopper 1 and the chute channel 2, the driver 42 drives the bridge-breaking plate 41 to rotate upward, so that the upper surface of the bridge-breaking plate 41 abuts against the blocked waste; then the power component 52 drives the insertion rod 51 to pass upward through the upper surface of the bridge-breaking plate 41 and insert into the blocked waste. Then the bridge-breaking plate 41 is rotated downward to the opening 6. At this time, the insertion rod 51 will pull the blocked waste downward, so that the blocked waste falls into the chute channel 2. Even the compacted waste can be hooked down, so that the connection between the lower end of the hopper 1 and the chute channel 2 is cleared; moreover, the rotating and rising insertion rod 51 can better insert into the compacted waste and better return to the lower surface of the bridge-breaking plate 41, so as to better adapt to different causes of bridging and smoothly clear the blockage, and improve the reliability of cleaning and clearing.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
