Description

Technical Field

[0001] This utility model relates to a feeding structure for a cylindrical screen, belonging to the field of cylindrical screen technology. Background Technology

[0002] Minerals refer to all natural mineral or rock resources buried underground that can be used by humans. Minerals can be divided into categories such as metals, non-metals, and combustible organics. They are non-renewable resources. After mining, minerals need to be crushed and screened. A cylindrical screen is a type of mechanical equipment commonly used in mineral screening.

[0003] Chinese patent CN215784804U proposes a feeding structure for a mining cylindrical screen, which uses a first screen in conjunction with a second screen to screen ore, thereby improving screening efficiency. However, in actual use, the ore falls through the feeding conveyor belt and hits the screen surface. Since the ore itself is hard and heavy, it will cause some deformation and damage to the screen, reducing the screen's service life and making it less practical. There is an urgent need for a feeding structure for a cylindrical screen to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a feeding structure for a cylindrical screen to solve the problems mentioned in the background art. The present utility model has a reasonable structure. Before the ore falls onto the screen, the gravitational potential energy of the ore can be absorbed by the movable seat, thereby avoiding damage to the screen by the ore, extending the service life of the screen, and making it highly practical.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a feeding structure for a cylindrical screen, comprising a screening chamber, a feeding cylinder, a control panel, a screen, a vibrating motor, a movable seat, a compression spring, a first fixed seat, and a second fixed seat. The feeding cylinder is welded to the upper end face of the screening chamber, a movable seat is provided inside the feeding cylinder, a control panel is installed on the front end face of the screening chamber, a screen is provided inside the screening chamber, a vibrating motor is provided above the screen, a first fixed seat is provided inside the screening chamber, a second fixed seat is provided above the first fixed seat, and a compression spring is provided between the first fixed seat and the second fixed seat.

[0006] Furthermore, the screening chamber has a cavity inside, the screen is placed inside the cavity, the right end of the screening chamber has a slot, and the screen is tilted towards the slot.

[0007] Furthermore, a vibration frame is welded to the upper surface of the screen, the vibration frame is in the shape of a gate, the vibration motor is installed on the upper surface of the vibration frame, and the control panel is electrically connected to the vibration motor through wires.

[0008] Furthermore, a mounting bracket is provided on the lower end face of the first fixed base, and the front and rear ends of the mounting bracket are fixedly connected to the inner wall of the screening chamber by fixing bolts.

[0009] Furthermore, the second fixed seat is fixedly connected to the lower end face of the movable seat by fixing bolts, and a buffer pad is bonded to the upper end face of the movable seat. The buffer pad is made of wear-resistant rubber.

[0010] Furthermore, a fixing sleeve is provided on the upper end face of the first fixing seat, and a sliding sleeve is provided on the lower end face of the second fixing seat, wherein the sliding sleeve slides tightly along the inner wall of the fixing sleeve.

[0011] Furthermore, the compression spring is sleeved on the outside of the fixed sleeve and the sliding sleeve, and spring seats are provided at both ends of the compression spring. The compression spring is fixedly connected to the first fixed seat and the second fixed seat through the spring seats.

[0012] The beneficial effects of this utility model are as follows: The feeding structure of this utility model for a cylindrical screen, due to the addition of a movable seat, a buffer pad, a first fixed seat, a second fixed seat, and a compression spring, allows the ore to be screened to fall onto the movable seat and impact the buffer pad first when it enters the feeding cylinder through an external conveying device. Under the gravity of the ore, the movable seat drives the second fixed seat and the sliding sleeve to move downward along the inner wall of the fixed sleeve, compressing the compression spring. Simultaneously, as the movable seat moves downward, the connection between the feeding cylinder and the cavity is no longer blocked. The ore enters the cavity through the left side of the movable seat and falls onto the surface of the screen. Subsequently, the vibration motor is turned on and drives the inclined screen to vibrate through the vibration frame. Under vibration, the ore is screened to remove fine soil impurities and discharged from the slot. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a feeding structure for a cylindrical screen, including a screening chamber 1, a feeding cylinder 2, a control panel 3, a screen 4, a vibrating motor 5, a movable seat 6, a compression spring 7, a first fixed seat 8, and a second fixed seat 9. The feeding cylinder 2 is welded to the upper end face of the screening chamber 1, and the movable seat 6 is arranged inside the feeding cylinder 2. The control panel 3 is installed on the front end face of the screening chamber 1, the screen 4 is arranged inside the screening chamber 1, the vibrating motor 5 is arranged above the screen 4, the first fixed seat 8 is arranged inside the screening chamber 1, the second fixed seat 9 is arranged above the first fixed seat 8, and the compression spring 7 is arranged between the first fixed seat 8 and the second fixed seat 9. This design solves the problem that the screen of the original cylindrical screen is easily damaged and deformed by the ore during the ore screening process.

[0021] As the first embodiment of this utility model: a cavity 12 is provided inside the screening chamber 1. The space on the left side of the cavity 12 is larger than the space of the feed cylinder 2. This design allows the ore to fall from the left side of the feed cylinder 2 into the cavity 12. The screen 4 is set inside the cavity 12. A slot 11 is provided at the right end of the screening chamber 1. The screen 4 is inclined towards the slot 11. The inclined screen 4 facilitates the screening and guidance of the ore. A vibration frame 51 is welded to the upper end of the screen 4. The vibration frame 51 is U-shaped. The vibration motor 5 is installed on the upper end of the vibration frame 51. The vibration motor 5 can drive the screen 4 to vibrate through the vibration frame 51. The control panel 3 is electrically connected to the vibration motor 5 through wires. The control panel 3 can control the opening and closing of the vibration motor 5. A mounting bracket 82 is provided on the lower end of the first fixed seat 8. The front and rear ends of the mounting bracket 82 are fixedly connected to the inner wall of the screening chamber 1 by fixing bolts. The mounting bracket 82 can fix the first fixed seat 8. The second fixed seat 9 is fixedly connected to the lower end face of the movable seat 6 by fixing bolts. The movable seat 6 can drive the second fixed seat 9 to move together. A buffer pad 61 is bonded to the upper end face of the movable seat 6. The buffer pad 61 is made of wear-resistant rubber and can absorb the gravitational potential energy of the falling ore. A fixed sleeve 81 is provided on the upper end face of the first fixed seat 8, and a sliding sleeve 91 is provided on the lower end face of the second fixed seat 9. The sliding sleeve 91 slides tightly along the inner wall of the fixed sleeve 81. The fixed sleeve 81 and the sliding sleeve 91 make the movable seat 6 move more stably in the vertical direction. The compression spring 7 is sleeved on the outside of the fixed sleeve 81 and the sliding sleeve 91. The compression spring 7 can help the movable seat 6 return to its original position. Spring seats 71 are provided at both ends of the compression spring 7. The compression spring 7 is fixedly connected to the first fixed seat 8 and the second fixed seat 9 through the spring seats 71. The spring seats 71 can fix the position of the two ends of the compression spring 7.

[0022] As a second embodiment of this utility model: when there is no ore inside the feed cylinder 2, the movable seat 6, in conjunction with the buffer pad 61, seals the connection between the feed cylinder 2 and the screening chamber 1. When the ore to be screened enters the feed cylinder 2 through an external conveying device, the ore falls first onto the movable seat 6 and impacts the buffer pad 61. Under the gravity of the ore, the movable seat 6 drives the second fixed seat 9 and the sliding sleeve 91 to move downward along the inner wall of the fixed sleeve 81, compressing the spring 7. Simultaneously, as the movable seat 6 moves downward, the connection between the feed cylinder 2 and the cavity 12 is no longer blocked, and the ore enters through the left side of the movable seat 6. Inside the cavity 12, the ore falls onto the upper surface of the screen 4. Then, the vibrating motor 5 is turned on and drives the inclined screen 4 to vibrate through the vibrating frame 51. Under the vibration, the fine soil impurities of the ore are screened out and discharged from the slot 11. The user can fix the slot 11 to the collection equipment to facilitate the collection of ore. When there is no ore inside the feed cylinder 2, the sealing effect of the moving seat 6 can prevent the dust generated during screening from overflowing through the feed cylinder 2. The design of the cavity 12 ensures that the ore always falls to the leftmost end of the screen 4, thereby ensuring that the ore has sufficient travel during the screening process to ensure the screening effect.
