[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0020] When using a traditional banana screen, the ore falls directly onto the top of the screen from the feed port. Since there is no buffer device at the bottom of the feed port, the ore itself is heavy and the long-term impact on the screen can easily damage the screen, reducing the service life of the screen. The screen needs to be replaced regularly, which increases the cost of ore screening.

[0021] In view of this, the utility model provides a linear double-layer banana screen for mineral screening. In the linear double-layer banana screen for mineral screening, the ore falls from the feed port to the top of the buffer device, and the ore slowly slides to the top of the screen through the buffer device. The ore will not impact the screen for a long time, thereby extending the service life of the screen, and there is no need to replace the screen regularly, thereby reducing the screening cost of the ore.

[0022] Example 1: By Figure 1 、 2, 3 and 4 show that a linear double-layer banana screen for mineral screening comprises a curved plate 1, a buffer device 2 is provided at the bottom of the curved plate 1, and the buffer device 2 comprises: a rotating plate 21, which is rotatably connected to the inner wall of the curved plate 1 through a pin; a slide bar 22, which is movably connected to the inner wall of the rotating plate 21; a straight rod 23, which is mounted on the outer wall of the slide bar 22; a spring 24, which is mounted on one end of the straight rod 23; an outer cylinder 25, which is movably connected to the outer wall of the straight rod 23 and is fixedly connected to one end of the spring 24; a rotating cylinder 26, which is mounted on the outer wall of the outer cylinder 25 and is rotatably connected to the inner wall of the curved plate 1 through a pin; wherein, after the rotating plate 21 is hit by the ore, the straight rod 23 is driven by the slide bar 22 to compress the spring 24, and at the same time the straight rod 23 contracts into the interior of the outer cylinder 25;

[0023] In the specific implementation process, it is worth noting that a shock absorber is provided between the straight rod 23 and the outer cylinder 25. When the rotating plate 21 is hit by the ore, it rotates downward. The rotating plate 21 drives the straight rod 23 to compress the spring 24 through the sliding rod 22, and at the same time, the straight rod 23 contracts and enters the inner part of the outer cylinder 25.

[0024] Furthermore, the outer wall of the bent plate 1 is installed with a side plate 3, the inner wall of the bent plate 1 is installed with a feed port 4, and the outer wall of the side plate 3 is installed with a banana screen body 5;

[0025] In the specific implementation process, it is worth noting that the feed port 4 facilitates the ore to enter the interior of the banana screen body 5;

[0026] Furthermore, a housing 6 is installed on the top of the banana screen body 5, a supporting leg 8 is installed on the bottom of the banana screen body 5, two screens 9 are installed on the inner wall of the banana screen body 5, and a vibration device 10 is installed on the top of the banana screen body 5;

[0027] In the specific implementation process, it is worth noting that the mesh size of the two sieves 9 is not specifically limited, and can meet the use requirements. The vibration device 10 is a prior art and will not be elaborated in detail.

[0028] Specifically, when the linear double-layer banana screen for mineral screening is used, the ore falls from the feed port 4 to the top of the buffer device 2, and the ore hits the turn plate 21. The spring 24 is compressed by the slide rod 22 and the straight rod 23. The straight rod 23 shrinks and enters the outer cylinder 25. At the same time, the turn plate 21 rotates a certain angle, so that the ore slowly slides to the top of the upper screen 9, thereby protecting the upper screen 9 and extending the service life of the upper screen 9. When the vibration device 10 is working, it drives the banana screen body 5 to vibrate, and the banana screen body 5 drives the two screens 9 to vibrate, thereby finely screening the ore.

[0029] Example 2: By Figure 1 、 2As shown in Figure 4, the inner wall of the shell 6 is provided with a dust removal device 7, which includes: a collection tank 71, mounted on the inner wall of the shell 6; a filter screen 72, mounted on the top of the collection tank 71; a collection pipe 73, connected to the inner wall of the shell 6, and connected to one side of the collection tank 71; a dust collecting port 74, mounted on the bottom of the collection pipe 73, and fixedly connected to the inner wall of the banana screen body 5; a vacuum part 75, mounted on the inner wall of the shell 6; wherein the vacuum part 75 draws the interior of the collection tank 71 into a negative pressure state, and the external air together with the dust enters the dust collecting port 74 and is stored in the interior of the collection tank 71 through the collection pipe 73;

[0030] In the specific implementation process, it is worth noting that the mesh number of the filter 72 is not specifically limited and can meet the use requirements. The exhaust pipe of the vacuum unit 75 is installed on one side of the housing 6. The vacuum unit 75 extracts the air inside the collection tank 71, causing a short-term negative pressure state inside the collection tank 71. The air above the screen 9 and the dust enter the dust collection port 74 and are stored in the collection tank 71 through the collection pipe 73.

[0031] Specifically, based on the above-mentioned embodiment 1, the vacuuming part 75 draws out the air inside the collection tank 71 when it is working, and the filter 72 can prevent dust from entering the interior of the vacuuming part 75. The external air and the dust enter the dust collecting port 74 together and are stored in the collection tank 71 through the collection pipe 73, thereby centrally processing the dust on the top of the upper screen 9.

[0032] Example 3: By Figure 2 and 4 As can be seen, the vacuum unit 75 includes: an air intake pipe 751, which is connected to the interior of the housing 6; a vacuum pump 752, which is detachably mounted on one end of the air intake pipe 751 and detachably connected to the inner wall of the housing 6; wherein the vacuum pump 752 extracts the air inside the collection tank 71 outward through the air intake pipe 751;

[0033] In the specific implementation process, it is worth noting that the model of the vacuum pump 752 is 2X-4G. When the vacuum pump 752 is working, it extracts the air inside the collection tank 71 through the suction pipe 751 and discharges it to the outside of the housing 6;

[0034] Specifically, based on the above-mentioned embodiment 1, when the vacuum pump 752 is working, it extracts the air inside the collection tank 71 through the suction pipe 751 and discharges the air to the outside of the shell 6.
