[0002] Silos are widely used in process industrial production and are an indispensable link in the material transportation and processing process. They are used to adjust and buffer the balance between the various operating procedures before and after to ensure the continuity of process production. In normal production, materials in granular material silos such as coal silos, ore silos, and mineral powder flow in the changing cone silos, forming a large extrusion pressure. Due to the large friction coefficient and repose angle between the materials, coupled with the influence of physical factors such as the moisture content, particle size composition, and surface shape of the materials, the materials have strong adhesion to each other, which makes them unable to flow out of the silo under their own weight, resulting in arching, crusting, blockage and other problems, resulting in an imbalance in the material ratio, which will not only affect normal production, but also cause great economic losses to the production enterprises in severe cases.

However, the vibrator has a large clearing area and makes a lot of noise. Long-term operation can easily cause cracks in the silo wall. Manual tamping is not only labor-intensive and inefficient, but also poses a safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0021] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0023] Reference Figure 1-4 A silo blockage clearing device comprises a silo body 1, symmetrically distributed mounting blocks 2 are fixedly connected to the two side surfaces of the silo body 1, a limiting slide groove 3 is provided on the upper surface of the mounting block 2, a limiting slider 4 is slidably connected to the inner wall of the limiting slide groove 3, a fixing plate 5 is fixedly connected to the upper surface of the limiting slider 4, the limiting slide groove 3 and the limiting slider 4 are used in coordination to limit the moving stroke of the fixing plate 5 and coordinate the stable movement, and a driving groove 6 is provided on the upper surface of the fixing plate 5;

[0024] A movable clearing device is provided on one side surface of the fixed plate 5 , and the movable clearing device comprises a mounting plate 7 , and one side surface of the mounting plate 7 is fixedly connected to one side surface of the fixed plate 5 .

[0025] A hydraulic cylinder 71 is fixedly installed on the other side surface of the mounting plate 7, and one end of the piston rod of the hydraulic cylinder 71 is fixedly connected to a moving block 72. The moving block 72 serves to extend the extended length of the piston rod of the hydraulic cylinder 71 and prevent the piston rod from being contaminated by materials. A scraper 73 is fixedly connected to the lower surface of the moving block 72. One side surface of the scraper 73 contacts the inner wall of one side of the silo body 1. A reinforcing block 74 is fixedly connected to the one side surface of the moving block 72. The reinforcing block 74 serves to prevent the scraper 73 from being deformed by the material squeezing and the moving block 72, thereby improving the connection strength. The lower surface of the reinforcing block 74 is fixedly connected to the upper surface of the scraper 73. The upper surface of the mounting block 2 is fixedly connected to a supporting block 75. The four supporting blocks 75 are symmetrically distributed in groups of two.

[0026] The inner wall of each group of support blocks 75 is installed with a screw rod 76 through a bearing, and a synchronous wheel 77 is fixedly sleeved on the outer surface of the screw rod 76. The inner walls of the two synchronous wheels 77 are transmission-connected with a synchronous belt 78. The synchronous wheel 77 and the synchronous belt 78 are used in conjunction with each other to achieve the synchronous rotation of the two screw rods 76, and can be replaced with a sprocket and a chain belt according to the usage. The outer surface of the screw rod 76 is threadedly connected with a threaded block 79, and the lower surface of the threaded block 79 is fixedly connected with a driving rod 710. One end of the driving rod 710 is movably plugged into the inner wall of the driving groove 6. The movably plugged connection between the driving groove 6 and the driving rod 710 forms a lifting and lowering activity space, thereby avoiding the damage of the screw rod 76 caused by the reverse thrust. A servo motor 711 is fixedly installed on the front side of one of the support blocks 75, and the output shaft of the servo motor 711 is fixedly connected to one end of one of the screw rods 76 through a coupling.

[0027] By setting up a mobile blockage clearing device, automatic mobile blockage clearing can be achieved according to the blockage position of the silo body 1, which not only reduces manual labor, but also eliminates the safety hazards of manual tamping and dredging, and improves the blockage clearing efficiency.

[0028] Working principle: Step 1, when the silo body 1 is partially blocked and the material discharge is not smooth, the servo motor 711 is started to drive one of the screw rods 76 to rotate clockwise, and the rotation of one of the screw rods 76 causes the two screw rods 76 to rotate synchronously through the cooperation of the synchronous wheel 77 and the synchronous belt 78, and the rotation of the screw rod 76 drives the threaded block 79 to move, and the movement of the threaded block 79 drives the fixed plate 5 to move through the cooperation of the driving rod 710 and the driving groove 6, and the fixed plate 5 moves stably through the cooperation of the limiting slider 4 and the limiting slide groove 3, thereby driving the hydraulic cylinder 71 to move to the blocked area through the mounting plate 7;

[0029] The second step is to start the piston rod of hydraulic cylinder 71 to extend. The extension of the piston rod of hydraulic cylinder 71 drives the scraper 73 to move out through the moving block 72. The movement of the scraper 73 scrapes and pushes the material stuck to the inner wall of the silo body 1, thereby destroying the arch and crust formed by the mutual adhesion of the materials, thereby clearing the blocked area. The use of the reinforcing block 74 can prevent the scraper 73 from being deformed due to the squeezing of the material and the moving block 72. The reverse thrust generated when the piston rod of hydraulic cylinder 71 is extended is prevented from acting on the screw rod 76 through the coordinated force of the limiting slide groove 3 and the limiting slide block 4 and the active plug-in coordination of the driving groove 6 and the driving rod 710, thereby ensuring the subsequent normal use of the screw rod 76.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
