DETAILED DESCRIPTION

[0021] 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 creative work are within the scope of protection of the present invention.

[0022] like Figure 1 As shown in Example 1, a vibrating screen feeding device includes a bracket 1, which is used to be fixed to the ground, thereby providing a support base for the entire device. A guide hopper 2 is fixedly connected to the bracket 1, and the guide hopper 2 is used to cooperate with the incoming material conveyor belt 3. The guide hopper can carry materials from the incoming material conveyor belt and gather and lower the materials. The guide hopper 2 is connected to the vibrating conveying component 4, which guides the materials transported from the incoming material conveyor belt to the vibrating conveying component. The vibrating conveying component 4 is connected to the output port 5, and the bracket 1 is provided with an adjustment mechanism 6 for adjusting the opening of the output port 5.

[0023] When in use, this embodiment utilizes a vibrating conveying assembly to vibrate and organize the material placed onto it, and vibrates and conveys it in a flat state to the output port at the end. The opening of the output port is adjusted using an adjustment mechanism based on the actual output. When the output is high, the opening of the output hopper is expanded to prevent material accumulation. When the output is low, the opening of the output port is reduced to prevent excessive dispersion of material conveying, thereby improving the quality of the vibratory feeding process. This device can flexibly adjust the opening of the output port at the conveying end of the vibrating screen feeding device, reducing manual labor and intervention and improving the quality and effect of feeding.

[0024] Example 2, based on Example 1, Figure 2 As shown, the vibrating conveying assembly 4 includes a screen bucket 41, the front end of the screen bucket 41 is open, and the output port 5 is arranged at the front end opening of the screen bucket 41, and the rear end of the screen bucket 41 cooperates with the guide hopper 2. A plurality of springs 42 are provided at the bottom of the screen bucket 41, and are connected to the base frame 43 through the springs 42. A vibrator 44 is fixedly provided at the bottom of the screen bucket 41. In this embodiment, the screen bucket itself can optionally have a certain inclination, and the output port is located on the lower side, which is more conducive to prompting the material to move toward the output port during the vibration of the vibrator. The base frame is fixed to the ground by anchor bolts, or fixedly connected to the bracket 1 to prevent displacement during vibration. The springs are arranged in pairs, and 4-10 springs can be optionally used. At the same time, the spring length should not be too long, as too long will easily cause the screen bucket platform to be unstable and tilted when bearing weight.

[0025] As a further specific embodiment, the vibrator 44 includes a double-headed motor 441 fixed to the bottom of the screen bucket 41. Both output ends of the double-headed motor 441 are provided with semicircular blocks 442. When the vibrating screen feeding device is in operation, power is supplied to the double-headed motor, and the output ends of the double-headed motor rotate, thereby driving the semicircular blocks to rotate, thereby generating vibration under the action of centrifugal force.

[0026] In this embodiment, the sieve 41 comprises a porous plate 412, the bottom of which is welded to a spring 42. A U-shaped hopper wall 413 is welded to the porous plate 412. The porous plate allows for the removal of impurities such as dust from the material, while also facilitating gas flow and reducing resistance during vibration. The U-shaped hopper wall blocks the three sides, excluding the outlet, to prevent material from falling and maintain the material conveying direction.

[0027] Example 3, based on Example 2, comprises a discharge port 5 comprising a port bottom plate 51 fixedly connected to the bottom of the opening of the sieve bucket 41. Baffles 52 are hingedly connected to the two sides of the opening of the sieve bucket 41. An adjustment mechanism 6 is fixedly mounted on the port bottom plate 51 and cooperates with the baffles 52. In this embodiment, hinged seats are provided on the bucket walls 413 on both sides of the discharge port, and one side of the baffle is hingedly connected to the hinged seats. Driven by the adjustment mechanism, the positions of the two baffles can be synchronously controlled to achieve the purpose of controlling the opening of the discharge port.

[0028] Furthermore, a symmetrical arcuate opening 53 is formed in the inlet bottom plate 51. A drive post 54 is provided at the bottom of the baffle 52. The drive post 54 passes through the arcuate opening 53 and engages with the adjustment mechanism 6. In this embodiment, the center of the arcuate opening coincides with the axis of the baffle's hinge. As a result, when the adjustment mechanism drives the drive post to move, it slides along the arcuate opening, simultaneously driving the baffle at its upper end to open and close along the hinge.

[0029] Example 4, based on Example 3, Figure 3 、4 As shown, the adjustment mechanism 6 includes a bidirectional lead screw 61 rotatably arranged at the bottom of the feed port bottom plate 51, a lead screw nut symmetrically provided on the bidirectional lead screw 61, and the lead screw nut is fixedly connected to a slider 62, an optical axis 63 is provided on the feed port bottom plate 51, the slider 62 slides in cooperation with the optical axis 63, and the drive column 54 cooperates with the slider 62. In this embodiment, the bidirectional lead screw includes two coaxially arranged lead screws with opposite rotation directions, which are connected by a coupling, and the outer ends are respectively rotatably cooperated with the lead screw seats fixed on the feed port bottom plate. When the bidirectional lead screw rotates, the sliders 62 on both sides can be driven to move toward or away from each other along the optical axis 63 through the transmission cooperation of the two lead screws with opposite rotation directions and the corresponding lead screw nuts, thereby driving the drive column 54 and the baffle 52 to open and close synchronously.

[0030] Furthermore, a track groove 64 perpendicular to the bidirectional screw 61 is provided on the slider 62, and the lower end of the drive column 54 is slidably arranged in the track groove 64. Furthermore, a rotary handle 65 is provided at the end of the bidirectional screw 61. When the opening needs to be adjusted, the rotary handle is rotated to electrically rotate the bidirectional screw, thereby driving the slider to move under the drive of the bidirectional screw, and the movement simultaneously drives the drive column to move along the axial direction of the screw. Under the hinged action of the baffle and the screen bucket, the drive column moves in the arc-shaped opening and slides in the track groove.

[0031] As a further embodiment, to maintain the baffle opening during normal loading, the bidirectional lead screw 61 is provided with a turntable 71 having a plurality of circumferentially spaced holes thereon. A latch 72 is slidably mounted on the feed inlet base plate 51, and the latch 72 engages with the holes. Specifically, in this embodiment, a support housing is provided on the feed inlet base plate, and the latch is slidably mounted on the support housing. A spring is provided between the support housing and the latch. Before adjusting the opening of the two baffles, the latch is pulled to remove its end from the hole on the turntable, compressing the spring. The handle is then rotated, driving the bidirectional lead screw to rotate and thereby adjust the relative opening of the two baffles. Once adjusted to the desired position, the latch is released. Under the return force of the spring, the latch end inserts into the corresponding hole, locking the turntable position and, in turn, the baffle position, maintaining the opening.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
