Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand feeding, in particular to a quartz sand feeding device. Background Art

[0002] Quartz sand is a sand-like material with quartz as the main component. It is a natural silicate mineral and is widely used in glass manufacturing, ceramic production, and construction industries. When producing quartz sand, it is often necessary to transport the material from a low place to a high place. Bucket elevator is a commonly used lifting equipment. Bucket elevator uses the bucket on the traction component to lift the material from a low place to a high place for loading. It is suitable for continuous vertical lifting of quartz sand materials.

[0003] When the bucket elevator is in use, materials are fed through the feed port at the bottom of the bucket elevator. However, if too much material is fed through the feed port at one time, the material is likely to accumulate at the bottom of the bucket elevator, affecting the operation of the bucket inside the bucket elevator, causing the bucket elevator to become stuck and affecting the transportation of materials. Summary of the invention

[0004] The utility model provides a quartz sand feeding device to solve the problem that materials enter the bucket elevator through the feeding port at one time, which easily causes the bucket elevator to be stuck. The quartz sand feeding device can make the materials enter the bucket elevator evenly and make the bucket elevator run smoothly.

[0008] Furthermore, a motor is fixed on the outer rear side surface of the box body, and the rear end of the rotating rod passes through the rear side plate of the box body and is connected to the output end of the motor.

The feed hopper 3 penetrates and is connected to the top plate of the box body 2 on the upper left side of the conveyor belt 4; the driving assembly includes a rotating rod 8 and a circular plate 9. A rotating rod 8 is rotatably provided in the box body 2 on the upper side of the rotating shaft 5. The rotating rod 8 is a round rod body. The front end of the rotating rod 8 movably penetrates the front side plate of the box body 2 and is connected to the circular plate 9. The upper part of the circumferential surface of the circular plate 9 is provided with teeth 10, which mesh with the gear 7 when the teeth 10 face downward; a gate plate 11 is provided in the box body 2. When the rotating rod 8 rotates, the gate plate 11 is driven by the transmission member to block or open the lower end opening of the feed hopper 3.

[0022] The left end of the bottom surface of the box body 2 is supported by a support plate 12, and the support plate 12 is a rectangular plate. The feed hopper 3 is a hollow quadrangular pyramid with a large top and a small bottom and openings at both ends. The connecting pipe 22 is a rectangular tube with openings at both ends, and the connecting pipe 22 is higher on the left and lower on the right. The left end opening of the connecting pipe 22 is connected to the right end opening of the box body 2, and the right end opening is connected to the feed port of the bucket elevator body 1.

[0023] A motor 13 is fixed on the outer rear side of the box body 2 , and the rear end of the rotating rod 8 passes through the rear side plate of the box body 2 and is connected to the output end of the motor 13 .

[0024] The gate plate 11 is located in the box body 2 on the upper side of the rotating rod 8. The gate plate 11 is a rectangular plate whose front and rear ends slide in contact with the front and rear inner surfaces of the box body 2 respectively. The left end of the gate plate 11 moves through the left side plate of the box body 2, and the top surface slides in contact with the top surface of the box body 2. The right part of the gate plate 11 covers the lower end opening of the feed hopper 3.

[0025] The transmission member includes a spring 14 and a drive ring 15. The left end of the bottom surface of the gate plate 11 is connected to a vertical plate 21. The spring 14 is connected between the vertical plate 21 and the left side plate of the box body 2. The drive ring 15 is fixedly mounted on the rotating rod 8. The drive ring 15 is a circular ring body. The lower part of the outer ring surface of the drive ring 15 is provided with a second tooth 16. The bottom surface of the gate plate 11 directly above the drive ring 15 is provided with a third tooth 17 from left to right. The second tooth 16 on the drive ring 15 engages with the third tooth 17 when facing upward. A through hole 18 is provided on the left side plate of the box body 2 for the gate plate 11 and the third tooth 17 to move through. When the spring 14 is in a natural state, the right end of the gate plate 11 is flush with the lower end of the inner side surface of the right part of the feed hopper 3.

[0026] A transverse plate 19 is provided between the rotating shaft 1 5 and the rotating shaft 2 6, and the front and rear ends of the transverse plate 19 are respectively fixedly connected to the front and rear side plates of the box body 2, and the upper and lower parts of the inner side surface of the conveyor belt 4 slide in contact with the transverse plate 19 respectively; a baffle 20 is fixed to the right end of the bottom surface of the gate plate 11, and the lower end of the baffle 20 slides in contact with the upper part of the outer side surface of the conveyor belt 4. The baffle 20 is a rectangular plate whose front and rear ends slide in contact with the front and rear inner surfaces of the box body 2, and the baffle 20 can prevent the quartz sand material from entering the box body 2 on the left side of the baffle 20.

[0027] When in use, the gate plate 11 blocks the lower opening of the feed hopper 3, and the quartz sand material is fed into the feed hopper 3; the motor 13 and the bucket elevator body 1 are started, and the motor 13 drives the rotating rod 8 to rotate counterclockwise (the counterclockwise rotation of the rotating rod 8 is Figure 2 The main viewing angle in the figure), when the rotating rod 8 rotates counterclockwise, it drives the circular plate 9 to rotate counterclockwise. When the tooth 10 on the circular plate 9 faces downward, the meshing gear 7 drives the rotating shaft 5 to rotate clockwise (the clockwise rotation of the gear 7 and the rotating shaft 5 is Figure 3The main viewing angle in the figure), the rotating shaft 15 drives the conveyor belt 4 to rotate clockwise. At the same time, when the rotating rod 8 rotates counterclockwise, the driving ring 15 rotates counterclockwise. When the tooth 2 16 on the driving ring 15 faces upward, the meshing tooth 3 17 drives the gate plate 11 to move leftward. The spring 14 is stretched. After the gate plate 11 moves leftward, the lower end opening of the feed hopper 3 is no longer completely covered. The quartz sand material in the feed hopper 3 falls into the upper part of the outer surface of the conveyor belt 4 through the lower end opening of the feed hopper 3 and is transported to the right. As the rotating rod 8 continues to rotate, the tooth 10 on the circular plate 9 disengages from the gear 7, the rotating shaft 15 no longer drives the conveyor belt 4 to rotate, the tooth 2 16 on the driving ring 15 disengages from the tooth 3 17, and the gate plate 11 is restored by the spring 14. Under the restoring force, it returns to the initial state to the right, blocking the lower end opening of the feed hopper 3; therefore, in the process of the motor 13 driving the rotating rod 8 to rotate continuously counterclockwise, the gate plate 11 is intermittently driven to open or block the lower end opening of the feed hopper 3, and the lower end opening of the feed hopper 3 intermittently feeds materials to the conveyor belt 4. While the feed hopper 3 intermittently feeds materials to the conveyor belt 4, the conveyor belt 4 also intermittently moves to the right, and the conveyor belt 4 can intermittently feed the materials on the conveyor belt 4 into the bucket elevator body 1 through the connecting pipe 22. The bucket elevator body 1 lifts the quartz sand material and feeds it, avoiding that all the materials in the feed hopper 3 enter the interior of the bucket elevator body 1 at one time, thereby ensuring smooth feeding of the bucket elevator body 1.

[0028] The preferred implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the above-mentioned embodiments. Without violating the spirit of the present invention, i.e., the disclosure scope, any equivalent or equivalent deformation or replacement of the technical solution of the present invention shall fall within the protection scope of the present invention.
