Description

Technical Field

[0001] The utility model relates to the technical field of automatic coal feeding, in particular to an automatic coal feeding device. Background Art

[0002] Automatic coal feeding device is an automated device used in coal-fired power plants, industrial boilers, thermal power stations and other places, aiming to achieve continuous, accurate and stable supply of coal to meet the heat load requirements of combustion equipment. This type of device integrates mechanical, electronic, control and other technologies to replace manual operation and improve the operating efficiency and safety of coal-fired systems.

[0003] The existing automatic coal feeding device controls the automatic supply of coal by opening and closing valves at the bottom of the prepared coal placement frame. However, since the coal is easily compressed into blocks when it is prepared and stacked, the coal guide port is easily blocked during coal feeding, and knocking or vibration is required to shake off the aggregated coal blocks, resulting in unsmooth coal feeding and affecting the fluency of the coal feeding operation.

[0004] Therefore, an automatic coal feeding device has been developed which can stir the prepared coal while feeding it intermittently to improve the smoothness of coal feeding. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art in the above-mentioned background technology, the utility model provides an automatic coal feeding device which can stir the prepared coal while feeding the coal intermittently, thereby improving the smoothness of feeding the coal.

[0006] The technical implementation scheme of the utility model is: an automatic coal feeding device, including a support frame, a placement frame, a fixed block, a first motor, a gear set, an opening and closing mechanism and a rotating mechanism, the left and right sides of the placement frame are rotatably connected to the support frame, the upper front side of the right support frame is connected to the fixed block, the fixed block is connected to the first motor, a gear set is provided between the output shaft of the first motor and the right side of the placement frame, an opening and closing mechanism is provided at the bottom of the placement frame, and a rotating mechanism is provided on the opening and closing mechanism.

[0007] In a preferred embodiment of the present invention, the placement frame is a cone-shaped structure.

[0008] In a preferred embodiment of the utility model, the opening and closing mechanism includes a fixed frame, a second motor, a rotating shaft, a transmission wheel, a rack, a first opening and closing plate and a second opening and closing plate. The fixed frame is connected to the right side of the lower part of the placement frame, the fixed frame is connected to the second motor, the second motor output shaft is connected to the rotating shaft, and the transmission wheel is connected to the rotating shaft. The first opening and closing plate is slidably connected to the lower side of the front of the placement frame, and the second opening and closing plate is slidably connected to the lower side of the rear of the placement frame. The first opening and closing plate and the right side of the second opening and closing plate are both connected to the rack, and the rack is meshed with the transmission wheel. The rotation of the second motor output shaft drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the transmission wheel to rotate. The rotation of the transmission wheel drives the first opening and closing plate and the second opening and closing plate to move closer to or away from each other through engagement with the rack. When the first opening and closing plate and the second opening and closing plate slide closer to each other, the first opening and closing plate and the second opening and closing plate are in a closed state, so that the coal in the placement frame cannot be discharged. When the first opening and closing plate and the second opening and closing plate move away from each other, the coal inside the placement frame can be discharged.

[0009] In a preferred embodiment of the utility model, a flexible sealing strip is provided on one side where the first opening and closing plate and the second opening and closing plate are close to each other.

[0010] In a preferred embodiment of the utility model, a rotating mechanism is also included, which includes a transmission assembly, a connecting shaft and a rotating frame. The rotating frame is rotatably connected to the interior of the placement frame, and the connecting shaft is connected to the right side of the rotating frame. A transmission assembly is provided between the connecting shaft and the second motor output shaft. When the second motor output shaft rotates, the connecting shaft is driven to rotate through the transmission assembly. The rotation of the connecting shaft drives the rotating frame to rotate. The rotation of the rotating frame stirs the coal inside the placement frame, making it more convenient to export the coal.

[0011] In a preferred embodiment of the utility model, the transmission assembly includes a pulley and a belt, the second motor output shaft and the connecting shaft are both connected with pulleys, and the belt is wound between the pulleys.

[0012] The beneficial effects of the utility model are as follows: the utility model controls the opening and closing of the first opening and closing plate and the second opening and closing plate by the second motor, and uses the transmission component to control the rotation of the rotating frame to stir the coal placed inside the placing frame. The prepared coal can be stirred while intermittently unloading the coal, thereby improving the smoothness of coal unloading. BRIEF DESCRIPTION OF THE DRAWINGS

A transmission assembly 71 is provided between the connecting shaft 72 and the output shaft of the second motor 62.

[0022] In use, the output shaft of the first motor 4 rotates through the gear set 5 to control the rotation of the placement frame 2, and the angle of the placement frame 2 is adjusted to adapt to the coal conveying device. The coal is conveyed to the placement frame 2 through the coal conveying device. The unloading of the coal in the placement frame 2 is controlled by the second motor 62. The output shaft of the second motor 62 rotates to drive the rotating shaft 63 to rotate. The rotation of the rotating shaft 63 drives the transmission wheel 64 to rotate. The rotation of the transmission wheel 64 drives the first opening and closing plate 66 and the second opening and closing plate 67 to move closer to or farther away from each other through the meshing with the rack 65.
