Description

Technical Field

[0001] This utility model relates to the field of cement storage equipment, specifically to a material feeding auxiliary mechanism for preventing blockage at the bottom of a cement silo. Background Technology

[0002] During prolonged use, cement silos are prone to blockages at the bottom due to the poor flowability of cement powder and changes in humidity, leading to poor material discharge. Currently, the main methods to solve the blockage problem are manual cleaning or vibration, but these have proven ineffective in practice. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cement silo bottom feeding auxiliary mechanism to promote feeding and prevent blockage.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A cement silo bottom unloading auxiliary mechanism includes a silo bottom, characterized in that a blockage-clearing component is assembled inside the silo bottom. The blockage-clearing component includes a fixed frame, a vertical column, a lifting sleeve, a rotating sleeve, a scraper, a driven gear ring, a driving gear, and a motor. The vertical column is fixedly connected to the fixed frame. Multiple vertical guide grooves are evenly formed along the circumference of the outer wall of the vertical column. Correspondingly, multiple guide blocks are fixedly connected along the circumference of the inner wall of the lifting sleeve. The number and position of the guide blocks correspond one-to-one with the vertical guide grooves, and each guide block is embedded in the corresponding vertical guide groove. A rotating sleeve is connected to and rotatably fitted around the outer circumference of the lifting sleeve. Two or four connecting rods are evenly hinged on the outer circumferential wall of the rotating sleeve. A scraper is hinged to the other end of each connecting rod. When the lifting sleeve descends to the lowest position of the vertical guide groove, the scraper is in contact with the inner wall of the silo bottom. A driven gear ring is fixedly connected to the bottom of the rotating sleeve. The driven gear ring meshes with the driving gear through its teeth. The driving gear is driven by a motor.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0007] This utility model incorporates a blockage-clearing component. When needed, the lifting sleeve is lowered to its lowest position, the scraper is opened, and then the rotating sleeve is driven by a motor, which in turn drives the scraper to rotate. The rising and falling motion of the lifting sleeve effectively promotes material feeding, resulting in good performance. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0009] The present invention will now be further described with reference to the accompanying drawings. Any parts not detailed below are based on existing technology and common knowledge in the field.

[0010] like Figure 1 As shown, this utility model discloses a cement silo bottom unloading auxiliary mechanism, including a silo bottom 10, within which a blockage-clearing component is assembled. The blockage-clearing component includes a fixed frame 1, a vertical column 2, a lifting sleeve 3, a rotating sleeve 4, a scraper 5, a passive gear ring 6, a driving gear 7, and a motor 8. The fixed frame 1 is fixedly connected to the vertical column 2, and multiple vertical guide grooves 2.1 are evenly formed along its circumference on the outer wall of the vertical column 2. Correspondingly, multiple guide blocks are fixedly connected along its circumference on the inner wall of the lifting sleeve 3. The number and position of the guide blocks correspond one-to-one with the vertical guide grooves, and each guide block is embedded in its corresponding vertical guide groove 2.1. The lifting sleeve 3 is rotatably fitted with a rotating sleeve 4 on its outer periphery. Two or four connecting rods 9 are evenly hinged on the outer periphery of the rotating sleeve 4, and a scraper 5 is hinged to the other end of each connecting rod 9. When the lifting sleeve 3 descends to the lowest position of the vertical guide groove 2.1, the scraper 5 is in contact with the inner wall of the silo bottom 1. A passive gear ring 6 is fixedly connected to the bottom of the rotating sleeve 4. The passive gear ring 6 meshes with the driving gear 7 to realize the vertical transmission of the two rotational forces. The driving gear 7 is driven by a motor 8, which is fixed at a suitable position on the vertical column 2. A traction rod or traction rope (which can extend from a suitable position in the cement silo) is fixedly connected to the top of the lifting sleeve 3 to drive the lifting sleeve 3 to move up and down.

[0011] When in use, the rotating sleeve 4 is located at the lowest position of the vertical guide groove. At this time, the scraper 5 is in contact with the inner wall of the tank bottom. Then, the rotating sleeve 4 is driven to rotate by the active gear, the passive gear ring, etc., thereby driving the scraper to rotate. After a period of time, the lifting sleeve 3 can be pulled up and down periodically to effectively prevent the tank bottom from being blocked.
