Description

Technical Field

[0001] This utility model relates to a vibrating feeder, and more particularly to a vibrating feeder for mineral conveying applied in the field of vibrating feeders. Background Technology

[0002] A vibrating feeder is a device that uses vibration to uniformly, regularly, and continuously transport lumpy or granular materials from storage containers or collectors to production lines or other equipment. Vibrating feeders are used in mineral conveying processes to break up the ore and achieve uniform transport.

[0003] A search revealed, for example, a vibrating feeder for mineral processing equipment disclosed in patent publication number CN222612102U, includes a frame, a vibrating hopper arranged on the frame, a feed bin fixed on the top of the frame, and a grating plate. The grating plate is fixed at the inlet end of the feed bin. The grating plate and the feed bin are inclined at the same angle, and the grating plate has a cross structure and is divided into several feed inlets. A baffle structure is arranged at the bottom of the feed bin. The baffle structure includes a fixed plate, guide rods, and a baffle. The fixed plate is fixed on the top side of the bottom end of the feed bin. Two guide rods are symmetrically inserted into the through holes opened at both ends of the fixed plate. The inner ends of the baffle are fixedly connected to one end of each of the two guide rods. The bottom end of the baffle is set as an inclined surface, and the bottom end of the baffle is inclined and aligned with the top side of the grating plate, which has the advantages of spreading the incoming ore and dispersing the vibration feeding.

[0004] However, the aforementioned vibrating feeder still requires the material to be evenly placed into the grid plate during feeding in order to achieve dispersed feeding at the vibrating hopper. Otherwise, the ore will still be concentrated in one place, and the vibration dispersion will take longer. Therefore, a vibrating feeder for mineral conveying is proposed to improve the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The core of this invention lies in using a drive assembly to drive a guide chute to reciprocate along the width of the vibrating feed hopper, ensuring that the mineral material in the guide chute falls evenly onto the feed hopper. This solves the problem in existing vibrating feeders with grid plates for dispersed feeding, where the material still needs to be evenly placed into the grid plates to achieve dispersed feeding at the vibrating hopper. Simultaneously, it can automatically adjust the material drop rate in conjunction with the movement of the guide chute.

[0007] 2. Technical Solution

[0008] To solve the above problems, this utility model provides a vibrating feeder for mineral conveying, including a frame and a vibrating feeder hopper installed on the upper end of the frame, and a vibrating motor is installed at the lower end of the vibrating feeder hopper. An auxiliary feeding mechanism is provided above the side of the frame that is inclined upwards on the vibrating feeder hopper.

[0009] The auxiliary feeding mechanism includes a mounting frame, a guide chute, and a drive assembly;

[0010] The mounting bracket is fixed to the side of the frame, the guide chute is located inside the mounting bracket, and the length direction of the guide chute is set in the same direction as the width direction of the vibrating feed hopper. The drive assembly is connected between the mounting bracket and the guide chute to drive the guide chute to move back and forth along the width direction of the vibrating feed hopper.

[0011] In the above-mentioned vibrating feeder for mineral conveying, the drive assembly drives the guide chute to move back and forth along the width direction of the vibrating feed hopper, which allows the mineral material in the guide chute to fall evenly onto the feed hopper, thus achieving decentralized feeding.

[0012] Furthermore, a spring is vertically installed between the frame and the vibrating feed hopper.

[0013] Furthermore, the drive assembly includes a drive motor and a threaded rod. The drive motor is mounted on the side of the mounting frame, and the threaded rod is horizontally rotatably mounted on the upper end of the mounting frame. One end of the threaded rod is coaxially fixed with the output end of the drive motor, and a connecting piece that is threadedly engaged with the threaded rod is installed on the guide chute.

[0014] Furthermore, a variable slope guide rail is fixed in the middle of the mounting frame, and a guide wheel adapted to the variable slope guide rail is installed on the side of the downward inclined end of the material guide chute. The upward inclined end of the material guide chute is rotatably connected to the connector.

[0015] Furthermore, the connectors include a connecting frame, a drive block, and a suspension bracket;

[0016] The drive block and the suspension bracket are fixed to the two axial ends of the connecting frame, respectively. The drive block is threaded onto the threaded rod, and the lower end of the suspension bracket is rotatably connected to the guide chute.

[0017] Furthermore, two sets of variable slope guide rails, guide wheels, and connectors are provided, and the two sets of variable slope guide rails, guide wheels, and connectors are located on opposite sides of the guide chute.

[0018] Furthermore, a flexible protective sleeve is fitted on the outer side of the threaded rod, and the two ends of the flexible protective sleeve are fixed to the mounting bracket and the drive block, respectively.

[0019] 3. Beneficial Effects

[0020] Compared with the prior art, the advantages of this invention are:

[0021] (1) This solution drives the guide chute to move back and forth along the width direction of the vibrating feed hopper through the drive component, so that the mineral material in the guide chute can fall evenly onto the feed hopper, thus realizing decentralized feeding.

[0022] (2) This scheme uses the combination of variable slope guide rail and guide wheel to make the inclination of the guide chute gradually increase as the lower end of the guide chute moves away from the feeding equipment, thereby increasing the amount of material falling, in order to compensate for the reduction of material falling caused by extending the guide path of the mineral material, so that the mineral material falling onto the vibrating feeder is more evenly dispersed.

[0030] The following describes one embodiment of this application in detail with reference to the accompanying drawings.

[0031] Example 1:

[0032] Figures 1-5 As shown, a vibrating feeder for conveying minerals includes a frame 1 and a vibrating feed hopper 2 installed on the upper end of the frame 1. Specifically, a spring 4 is vertically installed between the frame 1 and the vibrating feed hopper 2. A conventional vibrating motor 3 is installed at the lower end of the vibrating feed hopper 2 to realize the vibrating feeding action of the vibrating feed hopper 2.

[0033] The frame 1 is equipped with an auxiliary feeding mechanism located above the upward-sloping side of the vibrating feed hopper 2. Specifically, the auxiliary feeding mechanism includes a mounting frame 5, a guide chute 6, and a drive assembly. The mounting frame 5 is fixed to the side of the frame 1, and the guide chute 6 is located inside the mounting frame 5. The length direction of the guide chute 6 is aligned with the width direction of the vibrating feed hopper 2. The drive assembly is connected between the mounting frame 5 and the guide chute 6 to drive the guide chute 6 to move back and forth along the width direction of the vibrating feed hopper 2, so that the mineral material in the guide chute 6 can fall evenly onto the feed hopper 2, achieving decentralized feeding.

[0034] Regarding the drive assembly, specifically, the drive assembly includes a drive motor 7 and a threaded rod 8. The drive motor 7 is mounted on the side of the mounting bracket 5, and the threaded rod 8 is horizontally rotatably mounted on the upper end of the mounting bracket 5. One end of the threaded rod 8 is coaxially fixed with the output end of the drive motor 7. A connecting piece that is threadedly engaged with the threaded rod 8 is installed on the guide chute 6.

[0035] The drive motor 7 drives the threaded rod 8 to rotate, and the rotating threaded rod 8 drives the connecting piece to move back and forth along the width direction of the vibrating feed hopper 2 with the guide chute 6. This allows the mineral material in the guide chute 6 to fall evenly onto the feed hopper 2, achieving decentralized feeding.

[0036] In addition, considering that tiny particles from the splashing of mineral materials can easily get stuck on the surface of the threaded rod 8, a conventional flexible protective sleeve (not shown in the figure) is fitted on the outside of the threaded rod 8, such as a cloth sleeve or a rubber sleeve. The two ends of the flexible protective sleeve are fixed to the mounting bracket 5 and the drive block 11, respectively.

[0037] Example 2:

[0038] The difference from Embodiment 1 is that a variable slope guide rail 9 is fixed in the middle of the mounting frame 5, and a guide wheel 13 adapted to the variable slope guide rail 9 is installed on the side of the downward inclined end of the material guide chute 6. The upward inclined end of the material guide chute 6 is rotatably connected to the connector.

[0039] Correspondingly, the connecting parts include a connecting frame 10, a driving block 11, and a suspension frame 12. The driving block 11 and the suspension frame 12 are respectively fixed to the two axial ends of the connecting frame 10. The driving block 11 is threaded onto the threaded rod 8, and the lower end of the suspension frame 12 is rotatably connected to the guide chute 6.

[0040] like Figure 3 and Figure 4As shown, during the reciprocating movement of the guide chute 6 along the width direction of the vibrating feed hopper 2, the guide wheel 13 of the guide chute 6 reciprocates within the arc section of the variable slope guide rail 9. As the inclined lower end of the guide chute 6 moves toward the side away from the feeding equipment, the distance between the position of the mineral material falling onto the guide chute 6 and the inclined lower end of the guide chute 6 gradually increases, that is, the guiding path of the mineral material gradually increases. At this time, in order to compensate for the reduction in material falling caused by the extended guiding path of the mineral material, the inclination of the guide chute 6 gradually increases, thereby increasing the amount of material falling at the inclined lower end of the guide chute 6, so that the mineral material falling onto the vibrating feed hopper 2 is more evenly dispersed.

[0041] The variable slope guide rail 9, guide wheel 13 and connecting parts are provided in two sets, and the two sets of variable slope guide rail 9, guide wheel 13 and connecting parts are located on opposite sides of the guide chute 6, so that the guide chute 6 is subjected to more uniform force and runs more stably.

[0042] Working principle: The mineral material is fed onto the guide chute 6 using conventional feeding equipment. The drive motor 7 drives the threaded rod 8 to rotate, which in turn drives the connecting parts to move the guide chute 6 back and forth along the width of the vibrating feed hopper 2. This allows the mineral material in the guide chute 6 to fall evenly onto the feed hopper 2, achieving decentralized feeding. Furthermore, through the cooperation of the variable slope guide rail 9 and the guide wheel 13, the inclination of the guide chute 6 gradually increases as the lower end of the guide chute 6 moves away from the feeding equipment, thereby increasing the amount of material falling. This compensates for the reduced material falling due to the extended guide path of the mineral material, making the mineral material falling onto the vibrating feed hopper 2 more evenly dispersed.

[0043] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
