[0040] Embodiment 1

[0041] like Figure 1 As shown, the first aspect of the present application provides a vibrating screen feeder, including a main body 1 and a dividing assembly 2, the main body 1 having a feed channel 11 and two discharge channels 12, the two discharge channels 12 are respectively connected to the discharge end 113 of the feed channel 11; the dividing assembly 2 is arranged in the feed channel 11 and is rotatably connected to the main body 1, the dividing assembly 2 divides the feed channel 11 into a first channel 111 and a second channel 112, the first channel 111 and the second channel 112 correspond to the two discharge channels 12 respectively; rotating the dividing assembly 2 can change the feed diameter of the first channel 111 and the second channel 112.

[0042] Specifically, the body 1 of the vibrating screen feeder has a feed channel 11 and two discharge channels 12, so that the body 1 is Y-shaped, and two discharge channels 12 are usually symmetrically arranged and have the same diameter. The present application adds a dividing component 2 to the vibrating screen feeder to separate the feed channel 11 into a first channel 111 and a second channel 112, and can adjust the feed caliber of the first channel 111 and the second channel 112 in the feed channel 11 by rotating the dividing component 2, thereby changing the feed amount of the two channels, and then making the discharge amount of the two discharge channels 12 output to the vibrating screen different, so that without changing the total amount of feed, the discharge amount of the discharge channel 12 can be reduced for the side of the vibrating screen where the screen is biased, while the discharge amount can be increased on the other side, so that the side of the vibrating screen that increases the discharge amount can be partially offset to the side that reduces the discharge amount during the screening work, so as to ensure that the screen surfaces on both sides of the vibrating screen bear the same screening load and ensure the stability of the screening effect.

[0043] The portion of the feed channel 11 corresponding to the material distribution component 2 can be a square pipe, and the material distribution component 2 is provided with a square baffle to adapt to the square pipe to adjust the feed diameter of the first flow channel 111 and the second flow channel 112. In one embodiment, the square pipe is made of 304 stainless steel, and the material of the material distribution component 2 is 304 stainless steel.

[0044] The material distribution component 2 is rotatably connected to the feed channel 11, and may include a rotating shaft and a baffle, wherein the rotating shaft is rotatably connected to the body 1, and the baffle is connected to the rotating shaft so as to be driven to deflect by the rotation; it may also include a hinge and a baffle, wherein one end of the hinge is fixedly connected to the body 1, and the other end is connected to the baffle, and the baffle is driven to rotate in the feed channel 11 by driving the hinge. The driving component 2 may be driven to rotate by setting a driving motor connected to the rotating shaft or hinge to drive the baffle to rotate, or by setting a connecting structure outside the body 1, and applying a driving force to the connecting structure to drive the rotating shaft or hinge to drive the baffle to rotate.

[0045] The rotation center of the material distribution component 2 can be located at the center of the feed channel 11, or can be offset by a certain distance close to the center line, and can be adjusted according to the actual discharge demand, as long as the feed diameter of the first channel 111 and the second channel 112 can be changed after the material distribution component 2 is rotated. For example, when the two discharge channels 12 are symmetrically arranged and have the same diameter, the two discharge channels 12 each share half of the discharge volume of the feed channel 11. At this time, in order to facilitate the adjustment of the feed diameter by the material distribution component 2, the rotation center of the material distribution component 2 can be set to be located at the center line of the feed channel 11 and at the intersection of the two discharge channels 12.

[0046] It should also be noted that, considering that the discharge port of the discharge channel 12 of the vibrating screen feeder body 1 is softly connected to the vibrating screen through a cloth bag or canvas in the actual working scenario, the diameter of the discharge port of the present application should be set slightly smaller than the feed port of the vibrating screen to reduce the wear of the soft connection during the operation of the vibrating screening system.

[0047] A first aspect of the present application provides a vibrating screen feeder, comprising a main body 1 and a dividing assembly 2, the main body 1 having a feed channel 11 and two discharge channels 12, the two discharge channels 12 being respectively connected to a discharge end 113 of the feed channel 11; the dividing assembly 2 being arranged in the feed channel 11 and being rotatably connected to the main body 1, the dividing assembly 2 dividing the feed channel 11 into a first channel 111 and a second channel 112, the first channel 111 and the second channel 112 corresponding to the two discharge channels 12 respectively; rotating the dividing assembly 2 can change the feed diameters of the first channel 111 and the second channel 112. The present application adds a material distribution component 2 to the vibrating screen feeder, and can adjust the feed diameters of the first flow channel 111 and the second flow channel 112 in the feed flow channel 11 by rotating the material distribution component 2, thereby changing the feed amount of the two flow channels, and then making the discharge amounts of the two discharge flow channels 12 output to the vibrating screen different, so that without changing the total amount of feed, the discharge amount of the discharge flow channel 12 can be reduced for the side of the vibrating screen where the screen is biased, while the discharge amount can be increased on the other side, so that the side of the vibrating screen where the discharge amount is increased can be partially offset to the side where the discharge amount is reduced during the screening work, so as to ensure that the screen surfaces on both sides of the vibrating screen bear the same screening load, and ensure the stability of the screening effect. Through the application of the present application, the problem that the vibrating screen will be biased during operation, and uniform feeding will cause the screen surface on the side of the biased screen to bear a greater screening load, affecting the screening effect, is solved.

[0048] like Figure 1 As shown, in some embodiments, the material dividing assembly 2 includes a shaft 21 and a material dividing baffle 22, the shaft 21 is rotatably connected to the main body 1, and the material dividing baffle 22 is connected to the shaft 21; the driving shaft 21 drives the material dividing baffle 22 to rotate, and the material dividing baffle 22 deflects in the feed channel 11 to change the feed diameters of the first channel 111 and the second channel 112.

[0049] Specifically, the material distribution assembly 2 of the present application includes a shaft 21 and a material distribution baffle 22, the shaft 21 is rotatably connected to the body 1, and the material distribution baffle 22 is connected to the shaft 21. The driving shaft 21 can drive the material distribution baffle 22 to rotate, so that the material distribution baffle 22 deflects in the feed channel 11 and thus changes the feed diameters of the first channel 111 and the second channel 112. In this way, the discharge amounts of the two discharge channels 12 output to the vibrating screen are different, so that without changing the total amount of feed, the discharge amount of the discharge channel 12 can be reduced for the side of the vibrating screen where the screen is biased, while the discharge amount can be increased on the other side, so that the side of the vibrating screen where the discharge amount is increased can be partially offset to the side where the discharge amount is reduced during the screening operation, so as to ensure that the screen surfaces on both sides of the vibrating screen bear the same screening load and ensure the stability of the screening effect.

[0050] In one embodiment, the dividing baffle 22 can be arranged on a side edge close to the discharge end 113 and connected to the shaft rod 21. In another embodiment, the shaft rod 21 can be embedded in the dividing baffle 22. There is no specific limitation as long as the dividing baffle 22 is deflected by the rotation of the shaft rod 21. The setting position of the shaft rod 21 can be located on the center line of the feed channel 11, or it can be offset a certain distance close to the center line, as long as the dividing baffle 22 can change the feed diameters of the first channel 111 and the second channel 112 accordingly after deflection.

[0051] like Figure 1 As shown, in some embodiments, the shaft 21 is disposed on the center line of the feed channel 11 .

[0052] Specifically, in order to facilitate adjustment of the feed diameters of the first flow channel 111 and the second flow channel 112 , in one embodiment of the present application, the shaft 21 is disposed on the center line of the feed flow channel 11 . Since the first flow channel 111 and the second flow channel 112 are separated by the dividing baffle 22 in the feed flow channel 11, the dividing baffle 22 is connected to the shaft rod 21, and when the shaft rod 21 is set on the center line, the dividing baffle 22 is not deflected to any flow channel and is in a completely vertical state. The feed amount in the first flow channel 111 and the second flow channel 112 each accounts for half of the total feed amount of the feed flow channel 11. Therefore, when the vibrating screen is deflected, by adjusting the deflection angle of the dividing baffle 22, the proportion of the feed amount in the first flow channel 111 and the second flow channel 112 in the total feed amount of the feed flow channel 11 can be adjusted, and then the discharge amount of the discharge flow channel 12 is reduced on the side of the vibrating screen where the deflection occurs, while the discharge amount on the other side is increased, so that the side of the vibrating screen with increased discharge amount can be partially offset to the side with reduced discharge amount during screening, so as to ensure that the screen surfaces on both sides of the vibrating screen bear the same screening load and ensure the stability of the screening effect.

[0053] like Figure 1As shown, in some embodiments, the shaft rod 21 is arranged near the discharge end 113 of the feed channel 11 and is located at the intersection of the two discharge channels 12; the side edge of the material distribution baffle 22 near the discharge end 113 is fixedly connected to the shaft rod 21.

[0054] Specifically, in order to facilitate the adjustment of the distribution baffle 22 to deflect to either side of the first flow channel 111 or the second flow channel 112 to adjust the feed diameter, in the technical solution of the present application, the shaft rod 21 is arranged near the discharge end 113 of the feed channel 11 and is located at the intersection of the two discharge channels 12. One side of the distribution baffle 22 near the discharge end 113 is fixedly connected to the shaft rod 21. Such an arrangement enables the distribution baffle 22 to deflect to either side of the first flow channel 111 or the second flow channel 112, and the feed diameter of the corresponding side can be directly increased according to the deflection of the distribution baffle 22. Moreover, since the rotation axis of the distribution baffle 22 is located at the intersection of the two discharge channels 12, the slope provided after the distribution baffle 22 is deflected enables the increased material to directly and smoothly enter the corresponding discharge channel 12.

[0055] In some embodiments, the deflection of the material distribution baffle 22 has a deflection angle range, and the deflection angle range is 0° to 45°.

[0056] Specifically, when the material distribution baffle 22 changes the feed diameter of the first flow channel 111 and the second flow channel 112, the increased material in the flow channel on the side where the feed amount is increased will contact the surface of the material distribution baffle 22 during the movement, and continue to flow along the slope formed by the surface after the deflection of the material distribution baffle 22. In order to ensure smooth flow while adjusting the feed diameter of the material distribution baffle 22 and avoid material blockage, the deflection of the material distribution baffle 22 in the present application has a deflection angle range of 0° to 45°, and the deflection direction can be toward the first flow channel 111 or the second flow channel 112, and the maximum deflection angle toward the first flow channel 111 or the second flow channel 112 is 45°.

[0057] When the deflection angle of the material dividing baffle 22 is 0°, the material dividing baffle 22 is in a vertical state, and does not adjust the feed diameter of the first flow channel 111 and the second flow channel 112, and only serves to separate the feed flow channel 11. When the deflection angle of the material dividing baffle 22 is 45°, the material dividing baffle 22 is in an inclined state, and while increasing the feed diameter of the flow channel on one side, a 45° slope is provided for the material added to the side flow channel to ensure the flow of the material. And in another embodiment provided in the present application, when the deflection angle of the material dividing baffle 22 is 45°, that is, when the material dividing baffle 22 moves to the maximum deflection angle, the material dividing baffle 22 at 45° can be set to completely block one of the first flow channel 111 or the second flow channel 112, thereby achieving complete closure of any flow channel.

[0058] like Figure 2 and Figure 3As shown, in some embodiments, an adjusting rod 3 is further included. The adjusting rod 3 is arranged parallel to the material dividing baffle 22 . One end of the shaft rod 21 protrudes out of the body 1 and is fixedly connected to the first end of the adjusting rod 3 .

[0059] Specifically, in order to reflect the position state of the material distribution baffle 22 in the body 1 outside the body 1 of the vibrating screen feeder, and to facilitate the adjustment of the deflection angle of the material distribution baffle 22 outside the body 1, the present application is provided with an adjustment rod 3. The adjustment rod 3 is arranged parallel to the material distribution baffle 22 outside the body 1, and the first end of the adjustment rod 3 is fixedly connected to one end of the shaft rod 21 protruding outside the body 1. In this way, when the adjustment rod 3 deflects a certain angle, the material distribution baffle 22 in the body 1 also deflects the same angle, so that the position of the adjustment rod 3 outside the body 1 can reflect the position state of the material distribution baffle 22 in the body 1, thereby facilitating the operator to adjust the feed diameter of the first flow channel 111 and the second flow channel 112 from the outside of the body 1.

[0060] like Figure 2 and Figure 3 As shown, in some embodiments, a limit member 4 is provided on the outer wall of the main body 1, and a through hole 41 is opened in the limit member 4, and the through hole 41 extends along the rotation trajectory of the side edge of the material distribution baffle 22 away from the shaft 21; a fastener 31 is provided at the second end of the adjusting rod 3, and the end of the fastener 31 close to the main body 1 is at least partially connected to the through hole 41, driving the material distribution baffle 22 to rotate to a preset angle, and locking the fastener 31 to limit.

[0061] Specifically, in order to limit the deflection angle of the adjustment rod 3 and also make the rotation of the material distribution baffle 22 within the deflection angle range, the present application sets a limiter 4 on the outer wall of the main body 1. The limiter 4 can be a plate-like structure of any material, etc., connected to the outer wall of the main body 1 by welding or screws. The limiter 4 is provided with a through hole 41 for limiting, and the through hole 41 extends along the rotation trajectory of the side of the material distribution baffle 22 away from the shaft 21. The second end of the adjustment rod 3 is provided with a fastener 31, and the end of the fastener 31 close to the main body 1 is at least partially connected to the through hole 41. When the adjustment rod 3 is rotated, the fastener 31 can move along the through hole 41, drive the material distribution baffle 22 to rotate to a preset angle, and lock the fastener 31 to limit. When the fastener 31 moves to both ends of the through hole 41, the maximum deflection angle of the material distribution baffle 22 is reached. In one embodiment, the fastener 31 can be a bolt, which drives the adjusting rod 3 to move the bolt along the through hole 41. When the material dividing baffle 22 rotates to a preset angle, the locking bolt can be limited.

[0062] In an embodiment provided in the present application, when the vibrating screen deviates, the operator first unlocks the bolt and drives the adjusting rod 3 to make one end of the bolt move in the through hole 41 of the limiter 4, thereby adjusting the deflection angle of the material distribution baffle 22, and adjusting the side of the vibrating screen that causes the deviating screening to reduce the discharge amount of the discharge channel 12, while increasing the discharge amount on the other side. When the screen surfaces on both sides of the vibrating screen are adjusted to bear the same screening load, the bolts are tightened again and the adjustment is completed.

[0063] In some embodiments, a handle is provided on a side of the second end of the adjusting rod 3 facing away from the fastener 31 .

[0064] Specifically, in order to facilitate driving the adjustment rod 3 to move along the through hole 41 of the limiter 4 through the fastener 31, the present application provides a handle on the second end of the adjustment rod 3 away from the fastener 31. The specific form of the handle is not limited, as long as it is convenient for a person to grasp and drive the adjustment rod 3 to rotate around the shaft 21.

[0065] like Figure 1 As shown, in some embodiments, a thin flange 114 is provided at the feed end of the feed channel 11 .

[0066] Specifically, in the actual working environment, a feeding device such as a bucket elevator is arranged above the vibrating screen feeder. In order to make the feeding end of the feeding channel 11 of the vibrating screen feeder rigidly connected to the feeding device above, thereby avoiding equipment damage caused by wear of the soft connection or the suspension rope connection, and extending the operating life of the vibrating screening system, the feeding end of the feeding channel 11 of the present application is provided with a thin flange 114. The size of the thin flange 114 matches the size of the feeding channel 11 designed according to the feed amount required by the vibrating screening system.

[0067] Embodiment 2

[0068] A second aspect of the present application provides a vibrating screening system, comprising a vibrating screen and the above-mentioned vibrating screen feeder, wherein the vibrating screen has two feed ports, and two discharge channels 12 of the vibrating screen feeder are respectively connected to the two feed ports.

[0069] Specifically, please refer to Example 1 for the specific structure of the vibrating screen feeder, which will not be repeated here.

[0070] It should be noted that, considering that the discharge port of the discharge channel 12 of the vibrating screen feeder body 1 is softly connected to the vibrating screen through a cloth bag or canvas in the actual working scenario, the diameter of the discharge port of the discharge channel 12 of the vibrating screen feeder body 1 of the present application should be set to be slightly smaller than the feed port of the vibrating screen to reduce the wear of the soft connection during the operation of the vibrating screening system.

[0071] The second aspect of the present application provides a vibrating screening system, including a vibrating screen and the above-mentioned vibrating screen feeder, the vibrating screen having two feed ports, and the two discharge channels 12 of the vibrating screen feeder are respectively connected to the two feed ports. The vibrating screen feeder includes a body 1 and a material distribution component 2, the body 1 having a feed channel 11 and two discharge channels 12, the two discharge channels 12 are respectively connected to the discharge end 113 of the feed channel 11; the material distribution component 2 is arranged in the feed channel 11 and is rotatably connected to the body 1, the material distribution component 2 divides the feed channel 11 into a first channel 111 and a second channel 112, the first channel 111 and the second channel 112 correspond to the two discharge channels 12 respectively; rotating the material distribution component 2 can change the feed diameter of the first channel 111 and the second channel 112. The present application adds a material distribution component 2 to the vibrating screen feeder, and can adjust the feed diameters of the first flow channel 111 and the second flow channel 112 in the feed flow channel 11 by rotating the material distribution component 2, thereby changing the feed amount of the two flow channels, and then making the discharge amounts of the two discharge flow channels 12 output to the vibrating screen different, so that without changing the total amount of feed, the discharge amount of the discharge flow channel 12 can be reduced for the side of the vibrating screen where the screen is biased, while the discharge amount can be increased on the other side, so that the side of the vibrating screen where the discharge amount is increased can be partially offset to the side where the discharge amount is reduced during the screening work, so as to ensure that the screen surfaces on both sides of the vibrating screen bear the same screening load, and ensure the stability of the screening effect. Through the application of the present application, the problem that the vibrating screen will be biased during operation, and uniform feeding will cause the screen surface on the side of the biased screen to bear a greater screening load, affecting the screening effect, is solved.
