Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibrating conveyor technology, specifically to a high-efficiency vibrating feeder. Background Technology
[0002] Vibrating feeders are widely used in industries such as mining, building materials, and road construction. They are mainly used to uniformly transport mined or crushed blocky or granular stone materials (such as limestone, granite, basalt, etc.) from storage devices (such as silos and feed hoppers) to subsequent processing equipment (such as crushers, sand making machines, and screening machines). At the same time, they also need to take into account the initial sorting of materials to remove impurities or separate large stones that do not meet the standards, so as to ensure the processing efficiency and product quality of subsequent processes.
[0003] The current vibrating feeder's output is not regulated, which can easily cause blockages in subsequent crushers. Stones accumulate at the crusher's feed inlet, forming an arch. The moving and fixed jaws in the crushing chamber cannot mesh properly, requiring manual cleaning with hydraulic jacks. This not only delays production but may also lead to equipment failures such as crusher shaft bending and motor overload. When the subsequent crusher needs to reduce its throughput, it can only be adjusted by starting and stopping, resulting in material flow interruption and material surge upon restarting, further increasing the risk of blockages. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a high-efficiency vibrating feeder, comprising a feeding box with a feed hopper installed at one end of the top; a screen plate slidably connected inside the feeding box, the screen plate having multiple screen holes, the screen plate being inclined, and the upper end of the screen plate being closer to the feed hopper; a recovery port is provided on the side wall of the feeding box above the lower end of the screen plate; an inclined guide plate is fixed inside the feeding box below the screen plate; a discharge port is provided on the side wall of the feeding box above the lower end of the guide plate; a linear actuator is installed on the outer wall of the feeding box on the side with the discharge port above the discharge port; a baffle is fixed to the telescopic end of the linear actuator, the baffle being tightly against the outer wall of the feeding box and able to completely block the discharge port to adjust the opening degree of the discharge port; an anti-accumulation plate is fixed on the top of the inner wall of the feeding box near the feed hopper to prevent material from accumulating too high on the screen plate.
[0005] Furthermore, a rotating shaft is provided below the screen plate, with the axis of the rotating shaft parallel to the screen plate. One end of the rotating shaft extends to the outside of the feed box and is connected to a servo motor. An eccentric cam is fixed on the outer side of the rotating shaft. Spring washers are fixed on the inner wall of the feed box below both ends of the screen plate, and tension springs are fixed between the spring washers and the screen plate.
[0006] Furthermore, two protective plates are fixed between the front and rear walls of the feed box, and the two protective plates are respectively set on the sides of the tension springs at both ends.
[0007] Furthermore, two eccentric cams are provided at both ends of the rotating shaft, and the sieve holes of the sieve plate are located between the two eccentric cams.
[0008] Furthermore, an inclined transition plate is fixed inside the feed box between the screen plate and the guide plate. The transition plate is set parallel to the screen plate, and the inclination direction of the guide plate is opposite to that of the screen plate. The recovery port and the discharge port are located on two opposite side walls of the feed box.
[0009] Furthermore, conical hoppers are provided on the side of both the discharge port and the recovery port.
[0010] The beneficial effects of this utility model are as follows: 1. By setting up a material control structure, the baffle moves vertically to stably control the output within the design processing capacity of the subsequent crusher. The single feeding amount is controlled to avoid crusher blockage caused by overfeeding. By controlling the opening and closing size of the discharge port, the material is fed evenly, so that the crusher feed port can be kept full without overflowing, and the moving jaw and fixed jaw can mesh normally.
[0011] 2. Through the synergistic effect of inclined screen plate, composite vibration and anti-stacking plate, the problem of material accumulation is effectively solved. The inclined screen plate guides the movement of stone by the dual action of gravity and vibration, and the anti-stacking plate limits the passage of concentrated stone at the feed end through the guiding effect, so as to avoid the formation of material pile.

[0016] The present invention will be further described below with reference to the accompanying drawings: A high-efficiency vibrating feeder, such as Figure 1 and Figure 2 As shown, the system includes a feeding box 1, with a feed hopper 2 installed at one end of the top of the feeding box 1; a screen plate 3 is slidably connected inside the feeding box 1, with multiple screen holes on the screen plate 3, the screen plate 3 is inclined, and the upper end of the screen plate 3 is closer to the feed hopper 2; a recovery port 101 is opened on the side wall of the feeding box 1 above the lower end of the screen plate 3; an inclined guide plate 14 is fixed inside the feeding box 1 below the screen plate 3; a discharge port 102 is opened on the side wall of the feeding box 1 above the lower end of the guide plate 14; and the outer wall of the feeding box 1 on the side with the discharge port 102 is above the discharge port 102. A linear actuator 4 is installed, and a baffle 5 is fixed to the telescopic end of the linear actuator 4. The baffle 5 is close to the outer wall of the feed box 1 and can completely block the discharge port 102 to adjust the opening degree of the discharge port 102. An inclined transition plate 13 is fixed inside the feed box 1 between the screen plate 3 and the guide inclined plate 14. The transition plate 13 is set parallel to the screen plate 3. The inclination direction of the guide inclined plate 14 is opposite to that of the screen plate 3. The recovery port 101 and the discharge port 102 are located on two opposite side walls of the feed box 1. A conical collection hopper 15 is provided on the side of the discharge port 102 and the side of the recovery port 101.
[0017] like Figure 1 As shown in this embodiment, an anti-stacking plate 6 is fixed to the top of the inner wall of the feeding box 1 near the feeding hopper 2 to prevent the material from accumulating too high on the screen plate 3.
[0018] like Figure 1 As shown, in this embodiment, a rotating shaft 7 is provided below the screen plate 3. The axis of the rotating shaft 7 is parallel to the screen plate 3. One end of the rotating shaft 7 extends to the outside of the feed box 1 and is connected to a servo motor 8. An eccentric cam 9 is fixed on the outer side of the rotating shaft 7. Two eccentric cams 9 are provided at both ends of the rotating shaft 7. The screen holes of the screen plate 3 are located between the two eccentric cams 9. Spring washers 10 are fixed below both ends of the screen plate 3 on the inner wall of the feed box 1. Tension springs 11 are fixed between the spring washers 10 and the screen plate 3. Two protective plates 12 are fixed between the front and rear walls of the feed box 1. The two protective plates 12 are respectively located on the sides of the tension springs 11 at both ends.
[0019] The working principle of this utility model is as follows: When the gate of the feed hopper 2 is opened, the stone falls from the feed hopper 2 into the screen plate 3. The screen plate 3 guides the stone to move along the inclined surface of the screen plate 3. When the stone falls into the feed end of the screen plate 3, if the stone falls in a concentrated manner and forms a pile height, the anti-piling plate 6 can block the stone to prevent the stone from piling up too high, so that the stone can basically contact the screen plate 3. This avoids the stone piled up at the top from being difficult to screen. Qualified stone falls through the screen holes, while unqualified stone continues to move along the inclined screen plate 3.
[0020] The servo motor 8 is started, which drives the eccentric cams 9 at both ends to rotate via the rotating shaft 7. The cams lift the screen plate 3 to its highest point, and then the tension spring 11 pulls the screen plate 3 back, creating amplitude vibration. Large stones that do not meet the standards move along the lower end of the screen plate 3 to the recovery port 101 and enter the conical collection hopper 15 on the side of the recovery port 101. They can then be returned to the crusher for secondary crushing via a conveyor belt. Qualified stones that pass through the screen holes first fall onto the transition plate 13 inside the feed box 1. The transition plate 13 is designed to prevent qualified stones from falling directly onto the guide plate 14, reducing dust generated by stone impact. At the same time, the inclined structure of the transition plate 13 guides the qualified material to move at a uniform speed to the guide plate 14, preventing the qualified material from accumulating on the transition plate 13. The guide plate 14 adopts an inclination direction opposite to that of the screen plate 3, turning the qualified material for conveying, thus separating the qualified material flow from the recovery material flow.
[0021] When qualified stone material moves along the guide plate 14 to the discharge port 102, the linear actuator 4 is activated. The telescopic end of the linear actuator 4 is connected to the baffle 5, which is in close contact with the outer wall of the feed box 1 and can move up and down vertically. The extension and retraction of the cylinder can be controlled according to the subsequent processing requirements of the crusher, thus controlling the distance between the lower end of the baffle 5 and the bottom of the discharge port 102. When a slight blockage is detected at the crusher feed inlet, the linear actuator 4 extends, reducing the distance between the lower end of the baffle 5 and the bottom of the discharge port 102, achieving dynamic anti-blockage adjustment to avoid crusher blockage caused by overfeeding.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
