Embodiment Construction
[0026] The present invention will be further described in conjunction with accompanying drawings.
[0027] The structure of each component that constitutes the coal hopper anti-blocking device is as follows:
[0028] Screw drive device 1 such as figure 1 , 2 , 3 shown. Two base plates of the leading screw driving device 1 are installed on the outer sides of the coal hopper framework 9 .
[0029] Lead screw driving device 1 comprises: base plate 11, leading screw 12, leading screw coupling 13, drive motor 14, leading screw nut 15, slide block 16, sensor 17, leading screw nut connection block 18, lower bearing seat 19, upper Bearing block 20, upper support frame 21 of slide rail, lower support frame 22 of slide rail, guide rail 23, motor support plate 24, upper bearing 25, lower bearing 26.
[0030] The lead screw nut 15 and the lead screw nut connection block 18 are connected on the lead screw 12 in a threaded form to form a lead screw kinematic pair;
[0031] The upper be...

The invention relates to an anti-blocking device for a coal scuttle, which is suitable for cleaning and dredging the coal scuttle, and comprises a lead screw driving device (1), a transmission rod (2), an upper quadrilateral actuating mechanism (3), a connecting rod (4), a lower quadrilateral actuating mechanism (5), an upper wall scraping device (7) and a lower wall scraping device (8), wherein the lead screw driving device (1) is connected with an upper motor protective shell (31) through the transmission rod (2), and the upper quadrilateral actuating mechanism (3) is connected with the lower quadrilateral actuating mechanism (5) through the connecting rod (4); the upper quadrilateral actuating mechanism and the lower quadrilateral actuating mechanism are connected with the inner side of the skeleton of the coal scuttle through one side of each of the upper quadrilateral actuating mechanism and the lower quadrilateral actuating mechanism, and the lead screw driving device (1) is connected with the outer side of the skeleton of the coal scuttle; and motors of the upper and lower wall scraping devices are arranged in the upper motor protective shell and a lower motor protective shell. After a driving motor (14) is powered, a lead screw nut drives the upper quadrilateral actuating mechanism and the lower quadrilateral actuating mechanism to make reciprocating motion along the vertical direction through the transmission rod, and the motors of the wall scrapping devices drive scrapers to make circular motion after being powered.
Description
technical field [0001] The invention relates to an anti-blocking device for coal hoppers, which is suitable for coal hoppers in power plants and other occasions where a large amount of dense material flows. Background technique [0002] The coal hopper of the thermal power plant is an important equipment for the coal conveying system to convey coal to the boiler combustion system. The structure and shape of various types of coal hoppers are basically the same, the upper part is cylindrical, and the lower part is conical. The upper port is large and the lower port is small, and the upper port is fed with coal, and the coal material falls from top to bottom by its own weight. The falling coal material enters the coal mill through the coal feeder and is finally sent to the combustion chamber. In the actual operation process, the equipment generally has a serious problem of coal blockage. The clogging of the coal hopper will bring about serious consequences such as shutting d...
