Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See Figures 1-3 This utility model provides a technical solution:

[0025] A linear banana screen for screening mineral sand includes side wall plates 1, tail wall plates 2, upper crossbeams 3, lower crossbeams 4, longitudinal beams 5, upper screen 6, lower screen 7, reinforcing beams 8, a vibration assembly, a power assembly, and a frame assembly. Two side wall plates 1 are symmetrically arranged on the frame assembly. The tail ends of the two side wall plates 1 are fixedly connected by a tail wall plate 2. The lower parts of the two side wall plates 1 are fixedly connected by at least three lower crossbeams 4, which are arranged in an arc shape. The lower screen 7 is fixedly mounted on the lower layer by multiple longitudinal beams 5. On the crossbeam 4, the middle parts of the two side wall panels 1 are fixedly connected by at least three upper crossbeams 3. The three upper crossbeams 3 are arranged in an arc shape. The upper screen 6 is fixedly installed on the upper crossbeams 3 by multiple longitudinal beams 5. Both the upper screen 6 and the lower screen 7 are fixedly connected to the side wall panel 1 and the tail wall panel 2. The screen hole area on the upper screen 6 is larger than the screen hole area on the lower screen 7. The upper parts of the two side wall panels 1 are fixedly connected by reinforcing beams 8. A vibration assembly is installed on the top of the side wall panel 1, and the vibration assembly is connected to the power assembly on the side wall panel 1. A wall panel reinforcing beam 24 is installed on the upper part of the side wall panel 1. The two side wall panels 1 are fixedly connected at their lower parts by multiple lower crossbeams 4, at their middle parts by multiple upper crossbeams 3, and at their upper parts by multiple reinforcing beams 8. This connection method makes the entire linear banana screen structurally strong. The upper screen 6 is fixed to the upper crossbeam 3 by multiple longitudinal beams 5, and the lower screen 7 is fixed to the lower crossbeam 4 by multiple longitudinal beams 5, further securing the upper screen 6 and the lower screen 7. At the same time, both the upper screen 6 and the lower screen 7 are fixedly connected to the side wall panel 1 and the tail wall panel 2, further improving the structural strength of the linear banana screen. Multiple reinforcing beams 8 are set on the upper part of the side wall panel 1, which can effectively prevent the side wall panel 1 and the tail wall panel 2 from being damaged during use.

[0026] In some embodiments, the vibration assembly includes a vibrator beam 9, a vibrator assembly 10, and a vibrator protective cover 11. The two ends of the vibrator beam 9 are fixedly connected to two side wall plates 1, respectively. The vibrator assembly 10 is mounted on the vibrator beam 9 and is drivenly connected to the output end of the power assembly. The vibrator assembly 10 is housed within the vibrator protective cover 11. The two ends of the vibrator beam 9 are fixed to the side wall plates 1 on both sides. The vibrator beam 9 is used to mount the vibrator assembly 10 (as in the prior art). The vibrator assembly 10 drives the upper screen 6 and the lower screen 7 to vibrate. The vibrator protective cover 11 protects the vibrator assembly 10 and prevents damage to it.

[0027] In some embodiments, the power assembly includes a motor frame 12, a motor 13, a limiting drive shaft 14, and a flexible connector 15. The motor 13 is fixedly mounted in the middle of the motor frame 12. The limiting drive shaft 14 is mounted on the top of the motor frame 12. One end of the limiting drive shaft 14 is connected to the output shaft of the motor 13 via a V-belt 17, and the other end of the limiting drive shaft 14 is connected to the input end of the vibrator assembly 10 via the flexible connector 15. A connector protective cover 16 that mates with the flexible connector 15 is provided on the motor frame 12. A belt protective cover 18 that mates with the V-belt 17 is also provided on the motor frame 12. The motor frame 12 is independently fixed to the ground and is used to mount the existing motor 13. The limiting drive shaft 14 can only rotate on the motor frame 12 and will not move axially. The motor 13 drives the limiting drive shaft 14 to rotate via the existing V-belt 17. The limiting drive shaft 14 drives one end of the existing flexible connector 15 to rotate, and the other end of the flexible connector 15 drives the vibrator assembly 10 to work. Under the action of the flexible connector 15, the vibration on the vibrator assembly 10 will not be transmitted to the motor frame 12 and will not affect the motor 13. A protective cover 18 protects the V-belt 17, and a connector protective cover 16 protects the flexible connector 15.

[0028] In some embodiments, the frame assembly includes a screen frame 19, a spring 20, an upper spring seat 21, and a lower spring seat 22. The upper spring seat 21 and the lower spring seat 22 are respectively fixed to the lower ends of the side wall plate 1. A spring 20 is disposed between one end of the screen frame 19 and the upper spring seat 21, and a spring 20 is disposed between the other end of the screen frame 19 and the lower spring seat 22. A spring guard 23 that cooperates with the spring 20 is disposed on the side wall plate 1. In this embodiment, the body of the linear banana screen is inclined, so the upper spring seat 21 and the lower spring seat 22 are at different heights, with the upper spring seat 21 being higher than the lower spring seat 22. The upper spring seat 21 is disposed closer to the tail wall plate 2. The screen frame 19 is fixed to the ground. The upper spring seat 21 is connected to the screen frame 19 by multiple springs 20, in quantities of two, three, four, or five. The lower spring seat 22 is also connected to the screen frame 19 by multiple springs 20, in quantities of two, three, four, or five. All springs 20 are vertically arranged with the spring force pointing vertically upwards. Spring protective covers 23 are respectively installed on the upper spring seat 21 and the lower spring seat 22, protecting the springs 20 through the action of the spring protective covers 23.

[0029] In some embodiments, both the upper screen 6 and the lower screen 7 are provided with at least three segments, and the included angle between adjacent segments varies from 4 to 6°. Alternatively, both the upper screen 6 and the lower screen 7 are provided with five segments, with adjacent segments bent at angles of 4°, 5°, or 6°. An upper crossbeam 3 is provided below the bend of the upper screen 6, and an upper crossbeam 3 is provided below both ends of the upper screen 6. A lower crossbeam 4 is provided below the bend of the lower screen 7, and a lower crossbeam 4 is provided below both ends of the lower screen 7. Therefore, the two side wall panels 1 are fixedly connected by seven upper crossbeams 3 and seven lower crossbeams 4, resulting in higher strength for this linear banana screen.

[0030] In some embodiments, walkways 25 are provided on both sides of the frame assembly, and the upper ends of the two walkways 25 are connected by a platform 26. The linear banana screen in this technology is large in volume, and the walkways 25 on both sides allow access to the platform 26. Workers standing on the platform 26 can observe the working conditions inside the linear banana screen and also facilitate maintenance of the linear banana screen.
