Description

Technical Field

[0001] This utility model relates to the field of ore sorting, and in particular to a vibrating feeder for ore sorting. Background Technology

[0002] Vibrating feeders are key auxiliary equipment in ore sorting production lines. Their core function is to generate stable vibrations through a vibration drive mechanism, which uniformly, continuously, and quantitatively transports ore materials to subsequent sorting, crushing, and grinding equipment. They can also adapt to the conveying needs of ores of different particle sizes, providing a regular and stable supply of raw materials for ore sorting operations and ensuring the efficient operation of subsequent sorting processes.

[0003] In traditional devices, when adjusting the eccentric block, the operator needs to be in close contact with the eccentric component. Even if the power is off, the shaft may rotate unexpectedly, causing the operator's hands to be squeezed or scratched by the eccentric block, bolts, and other components. Furthermore, the eccentric component is usually installed at both ends of the vibratory motor, and may be obstructed by components such as the frame and trough, resulting in a narrow operating space. This requires bending over and reaching into the equipment when removing bolts, which can cause the hands to come into contact with rotating parts or sharp edges, resulting in scratches or bumps. Utility Model Content

[0004] The main purpose of this utility model is to provide a vibrating feeder for ore sorting, which can effectively solve the problem of insufficient safety of manually adjusted eccentric components.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vibrating feeder for ore sorting includes a base, a shock absorber 1 fixedly connected to the top of the base, a vibration drive assembly fixedly connected to the top of the shock absorber 1, a support frame fixedly connected to the top of the vibration drive assembly, a second shock absorber 2 rotatably connected to the outer side of the support frame, the other end of the second shock absorber 2 being rotatably connected to the base, and a feeding trough fixedly connected to the top of the support frame.

[0006] Preferably, the vibration drive assembly includes a base, a power chamber fixedly connected above the base, a rotating shaft rotatably connected to the center of the power chamber, a motor installed in the power chamber and driving the rotating shaft to rotate, an eccentric plate two fixedly connected below the rotating shaft, an eccentric plate one rotatably connected above the rotating shaft and the power chamber, a counterweight fixedly connected above both the eccentric plate one and the eccentric plate two, a transmission ring fixedly connected above the rotating shaft and an internal gear ring fixedly connected below the transmission ring.

[0007] Preferably, a guide rail is fixedly connected above the eccentric plate, a locking block is slidably connected to the inner side of the guide rail, a rubber block is fixedly connected above the guide rail, and the locking block meshes with the internal gear ring.

[0008] Preferably, the eccentric plate is fixedly connected to a limit block on the inner side of the locking block, and a guide rod is fixedly connected to the outer side of the limit block. The guide rod is slidably connected to the locking block, and a spring is sleeved on the outer side of the guide rod.

[0009] Preferably, a boss is fixedly connected to the lower part of the card block, a sliding groove is provided on the outer side of the boss and a slider is slidably connected thereto, a positioning frame is fixedly connected to the outer side of the slider, and a positioning pin is fixedly connected to the bottom of the eccentric plate.

[0015] 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.

[0016] like Figure 1 As shown, this utility model provides a vibrating feeder for ore sorting, including a base 1, a shock absorber 2 fixedly connected to the top of the base 1, a vibration drive assembly 6 fixedly connected to the top of the shock absorber 2, a support frame 3 fixedly connected to the top of the vibration drive assembly 6, a second shock absorber 4 rotatably connected to the outside of the support frame 3, and the other end of the second shock absorber 4 rotatably connected to the base 1. A feeding trough 5 is fixedly connected to the top of the support frame 3. The vibration drive assembly 6 is connected to the top of the base 1 through the shock absorber 2, which can absorb the vertical vibration impact force. The vibration generated by the operation of the vibration drive assembly 6 is transmitted to the feeding trough 5 through the support frame 3 above. The second shock absorber 4 rotatably connected to the outside of the support frame 3, with the other end fixed to the base 1, can buffer the horizontal vibration and prevent the overall shaking of the equipment.

[0017] like Figure 2As shown, this utility model provides a vibrating feeder for ore sorting. The vibration drive assembly 6 includes a base 61, a power chamber 62 fixedly connected above the base 61, a rotating shaft 63 rotatably connected to the center of the power chamber 62, a motor inside the power chamber 62 driving the rotating shaft 63 to rotate, an eccentric plate 68 fixedly connected below the rotating shaft 63, an eccentric plate 67 rotatably connected above the power chamber 62, counterweights 66 fixedly connected above both the eccentric plate 67 and the eccentric plate 68, a transmission ring 64 fixedly connected above the eccentric plate 67, and an internal gear fixedly connected below the transmission ring 64. Ring 65 and base 61 are fixed above shock absorber 2, providing installation support for power chamber 62. After the motor in power chamber 62 is powered on, the rotating shaft 63 in the drive center rotates, providing a power source for the entire vibration system. Then, the rotating shaft 63 synchronously drives the transmission rings 64 and eccentric plates 68 at both ends to rotate. At the same time, the internal gear ring 65 fixed below the transmission ring 64 meshes with the locking block 69, thereby driving the eccentric plate 67 to rotate. Counterweights 66 are fixed above both eccentric plates 67 and eccentric plates 68. When the two rotate synchronously, the counterweights 66 generate centrifugal force, which combines to form a continuous and stable excitation force, causing the vibration drive assembly 6 to vibrate and providing power for feeding.

[0018] like Figure 3 As shown, this utility model provides a vibrating feeder for ore sorting. A guide rail 610 is fixedly connected above an eccentric plate 67. A locking block 69 is slidably connected to the inner side of the guide rail 610. A rubber block 613 is fixedly connected above the guide rail 610. The locking block 69 meshes with an internal toothed ring 65. A limit block 611 is fixedly connected to the inner side of the locking block 69 on the eccentric plate 67. A guide rod 612 is fixedly connected to the outer side of the limit block 611. The guide rod 612 is slidably connected to the locking block 69. A spring is fitted on the outer side of the guide rod 612. The guide rail 610 fixed above the eccentric plate 67 provides a sliding track for the locking block 69, ensuring that the locking block 69 can only move laterally along the guide rail 610. The limiting block 611 on the inner side of the eccentric plate 67 has a guide rod 612 fixed on its outer side. The guide rod 612 is slidably connected to the locking block 69, providing guidance for the sliding of the locking block 69. The spring fitted on the outer side of the guide rod 612 normally pushes the locking block 69 to mesh with the internal gear ring 65, ensuring that the transmission does not disengage.

[0019] like Figure 4As shown, this utility model provides a vibrating feeder for ore sorting. A boss 614 is fixedly connected to the lower part of the locking block 69. An eccentric plate 67 has a groove on the outer side of the boss 614 and a slider 615 is slidably connected thereto. A positioning frame 616 is fixedly connected to the outer side of the slider 615. A positioning pin 621 is fixedly connected to the bottom of the eccentric plate 67. The boss 614 fixed below the locking block 69 receives the adjustment power. The groove at the bottom of the eccentric plate 67 provides sliding space for the slider 615. When the included angle needs to be adjusted, the electric push rod 617 pushes the positioning frame 616 to move inward. The positioning frame 616 drives the slider 615 to slide along the groove. The slider 615 presses against the boss 614, thereby pushing the locking block 69 to slide inward along the guide rail 610 and disengage from the inner toothed ring 65.

[0020] like Figure 5 As shown, this utility model provides a vibrating feeder for ore sorting. An electric push rod 617 and a guide rod 618 are fixedly connected to the outside of the positioning frame 616. A guide sleeve 619 is slidably connected to the outside of the guide rod 618. Both the guide sleeve 619 and the electric push rod 617 are fixedly connected to the base 1. A reinforcing plate 620 is fixedly connected to the outside of the guide sleeve 619 and the electric push rod 617 on the base 1. The reinforcing plate 620 is fixedly connected to the guide sleeve 619 and the guide rod 618. The guide sleeve 619 and the electric push rod 617 are both fixed on the base 1 to ensure stable power transmission for adjustment. The reinforcing plate 620 fixed to the outside of the base 1 is fixed to the guide sleeve 619 and the guide rod 618 respectively, which enhances the rigidity of the guiding structure and prevents deformation of the components during adjustment.

[0021] The working principle of the vibrating feeder selected for this ore sorting will be explained in detail below.

[0022] like Figure 1-5As shown, during use, the motor in the power chamber 62 is first started, driving the internal rotating shaft 63 to rotate; then the rotating shaft 63 synchronously drives the eccentric plates 68 and transmission ring 64 fixed at both ends to rotate, providing basic power for vibration. At this time, the positioning frame 616 is located outside the eccentric plate 67, and the spring outside the guide rod 612 is in a naturally extended state, pushing the locking block 69 to tightly mesh with the internal gear ring 65 below the transmission ring 64; because the locking block 69 is slidably connected to the eccentric plate 67 through the guide rail 610, the rotating shaft 63 drives the eccentric plate 67 to rotate synchronously through the meshing transmission ring 64 to the internal gear ring 65 and then to the locking block 69; when the eccentric plates 67 and 68 rotate, the counterweight 66 above them generates centrifugal force, forming a continuous The stable excitation force causes the entire vibration drive assembly 6 to vibrate. Simultaneously, the rubber block 613 above the guide rail 610 limits the sliding stroke of the locking block 69, preventing it from disengaging from the guide rail 610. The vibration of the vibration drive assembly 6 is transmitted to the upper feeding trough 5 via the support frame 3. Under the action of vibration, the ore in the feeding trough 5 slides evenly downwards along the slope of the trough, continuously conveying it to the subsequent sorting equipment to complete the feeding operation. When it is necessary to adjust the vibration intensity, the angle of the eccentric plate can be changed to adapt to the vibration frequency. When it is necessary to adjust the angle between eccentric plate one 67 and eccentric plate two 68, the electric push rod 617 is energized and extends, pushing the outer fixed positioning frame 616 inwards until the positioning frame 616 is in contact with the bottom of eccentric plate one 67. During this process... The guide rod 618 slides along the guide sleeve 619, providing stable support for the positioning frame 616. Simultaneously, the rotating shaft 63 drives the eccentric plate 67 to rotate slightly, causing the positioning pin 621 at the bottom of the eccentric plate 67 to engage with the positioning frame 616, achieving initial positioning of the eccentric plate 67. The electric push rod 617 continues to push the positioning frame 616, which in turn drives the inner slider 615 to slide along the groove at the bottom of the eccentric plate 67. The slider 615 contacts and pushes the boss 614 below the locking block 69, causing the locking block 69 to slide inward along the guide rail 610, compressing the spring on the outer side of the guide rod 612 until the locking block 69 completely disengages from the inner toothed ring 65, releasing the meshing transmission between the eccentric plate 67 and the rotating shaft 63. After the locking block 69 disengages, the slider 615 locks... The eccentric plate 67 is inserted into the groove of the eccentric plate 67 and braked to its current position. The rotating shaft 63 continues to rotate, only driving the eccentric plate 68 to rotate, until the eccentric plate 67 and the eccentric plate 68 form the target angle. After the adjustment is completed, the electric push rod 617 retracts, driving the positioning frame 616 and the slider 615 to retract outward. The slider 615 disengages from the boss 614 and the groove of the eccentric plate 67. The spring on the outside of the guide rod 612 resumes extension, pushing the locking block 69 to engage with the internal gear ring 65 again. The eccentric plate 67 rotates again with the rotating shaft 63, and the equipment resumes normal vibration feeding. The impact force generated when the vibration drive component 6 works is transmitted to the base 1 through the shock absorber 2 at the bottom. The shock absorber 2 can absorb part of the vertical vibration energy.Meanwhile, the shock absorber 4, which is rotatably connected to the outer side of the support frame 3, has its other end rotatably connected to the base 1, which can buffer horizontal vibration and impact forces, extending the service life of the equipment.
