Description

Technical Field

[0001] The invention relates to the technical field of cement silo feeding, in particular to a cement silo feeding structure. Background Art

[0002] Cement silos (also known as cement tanks) are sealed containers used to store bulk cement, fly ash, mineral powder, and other powdered materials. They are widely used in construction, concrete mixing plants, cement production plants, and other fields. When a cement silo is in use, a feeding mechanism is required to transport the cement into the silo.

[0003] After searching, the Chinese patent with application number "CN202020017740.7" is specifically a new type of cement silo feeding structure, including a cement silo main body and a conveyor belt main body. The outer wall of the feed port of the cement silo main body is provided with a dustproof cover, and the left end of the conveyor belt main body is placed directly above the feed port of the cement silo main body. The upper side wall of the feed port of the cement silo main body is fixedly installed with a feed box body, and the inner side wall of the feed box body is hinged with a baffle. The inner side wall of the feed box body is provided with a slide groove, and the lower side wall of the slide groove is embedded with a push rod motor, and the output end of the push rod motor is fixedly installed with a push block.

[0034] Example 2

[0035] Based on the first embodiment, Figure 8As shown, a vibration assembly 87 is provided on the lower side of the guide plate 862, and the vibration assembly 87 includes a guide plate 871, and the outer side of the guide plate 871 is slidably connected to two guide blocks 872, and the outer sides of the two guide blocks 872 are fixedly connected to a connecting rod 873, and the outer ends of the connecting rod 873 are fixedly connected to a metal block 1 874, and the lower side of the guide plate 862 is fixedly connected to two metal blocks 2 875, and the lower sides of the two guide blocks 872 are fixedly connected to a connecting block 3 876, and the outer side of the connecting block 3 876 is rotatably connected to an inclined plate 877, and the outer side of the lower end of the inclined plate 877 is rotatably connected to a connecting block 4 878, and the lower side of the connecting block 4 878 is fixedly connected to a contact block 879, and the lower side of the contact block 879 is fixedly connected to two mounting blocks 8710, and a contact wheel 8711 is provided between the two mounting blocks 8710. A telescopic rod 8712 and a second spring 8713 are fixedly connected between the plates 862. The two inclined plates 877 are symmetrically distributed.

The metal block 1 874 repeatedly collides with the metal block 2 875, generating vibrations. These vibrations cause the cement adhered to the guide plate 862 to fall quickly, thereby avoiding the accumulation of cement.

[0036] Working principle: When in use, the staff first places the cement on the conveyor belt 5 and conveys the cement. The cement falls onto the guide plate 862. Since the guide plate 862 is an inclined structure, the cement falls to the bottom of the feeding frame 1 and falls into the cement silo.

[0037] When feeding, start the motor 3, the motor 3 drives the rotating rod 81 to rotate, the rotating rod 81 drives the rotating plate 8626 to rotate, the rotating plate 8626 drives the control plate 8625 to rotate, and the control plate 8625 drives the rear plate 8624 to move up and down repeatedly.

At the same time, the baffle 85 drives the gear 8622 on the control rod 8621 to swing. Since the gear 8622 is meshed with the arc-shaped tooth plate 8611, the gear 8622 rotates. Under the control of the control rod 8621, the cam 8620, and the arc block 8610, the gear 8622 rotates. 619 and the connecting plate 8618, the L-shaped plate 8617 is controlled to move repeatedly left and right. Under the action of the slider 8613 and the support plate 8615, the guide plate 862 is controlled to swing repeatedly, increasing the swing amplitude of the guide plate 862. When the guide plate 862 swings, the guide plate 862 drives the contact wheel 8711 to contact the baffle 85, controlling the contact block 879 to move up and down repeatedly. Under the action of the inclined plate 877, the guide block 872 and the connecting rod 873, the metal block 1 874 is controlled to collide with the metal block 2 875 repeatedly, generating vibration, so that the cement adhered to the guide plate 862 is cleaned off, reducing the workload of the staff.
