[0020] To further illustrate the embodiments, the utility model provides the drawings. These drawings are part of the utility model disclosure, which mainly serves to illustrate the embodiments, and can be combined with the related description of the specification to explain the operation principle of the embodiments. With reference to these contents, those skilled in the art should understand other possible embodiments and the advantages of the utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0021] In the description of the present application, the terms "upper", "lower", "left", "right", "front", "back" and the like orientation or position relationship are based on the orientation or position relationship shown in the drawings, which is only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the present application.

[0022] The utility model will be further described in conjunction with the drawings and specific embodiments.

[0023] Reference Figs. 1 to 3As shown, the vibrating feeder provided by the embodiment comprises a fixed base 10, a vibrating machine 40 and a long strip-shaped conveying bin 20. The long strip-shaped conveying bin 20 has a long strip-shaped conveying channel and can convey materials over a long distance. The conveying bin 20 is assembled on the fixed base 10 through damping elastic members 30. The conveying bin 20 has opposite first and second ends in the length direction thereof. The vibrating machine 40 acts on the first end of the conveying bin 20. The conveying bin 20 is provided with a feeding port 201 near the first end thereof and a discharging port 202 at the second end thereof.

[0024] One working process is as follows: the materials in the incoming bin 1 enter the conveying bin 20 from the feeding port 201 of the conveying bin 20. The vibrating machine 40 acts on the first end of the conveying bin 20, i.e. the first end of the conveying bin 20 has the maximum vibration intensity. The vibration intensity of the conveying bin 20 decreases from the first end to the second end, so that the materials are smoothly conveyed from the feeding port 201 to the discharging port 202 and discharged, effectively solving the problem of material blocking during long-distance vibration conveying. In addition, the vibration transmission effectively avoids the generation of magnetic materials (i.e. the vibration effectively avoids excessive friction between metal materials to generate magnetic materials) and other abrasion during pushing.

[0025] The vibrating feeder of the application can convey and feed powdery materials, granular materials, blocky materials and materials with high humidity.

[0026] In the embodiment, the damping elastic members 30 are provided in multiple groups and are distributed at intervals along the length direction of the conveying bin 20, effectively supporting the conveying bin 20. Each group of damping elastic members 30 comprises two damping elastic members and is connected to the two sides in the width direction of the conveying bin 20, so that the conveying bin 20 is more stable during installation. Specifically, the damping elastic members 30 are springs. The fixed base 10 and the conveying bin 20 are both provided with positioning columns. The two ends of the spring are respectively sleeved on the positioning column 11 of the fixed base 10 and the positioning column 23 of the conveying bin 20. One installation method is as follows: first, the lower end of the spring is sleeved on the positioning column 11 of the fixed base 10. After all the springs are installed, the positioning column 23 of the conveying bin 20 is finally inserted into the upper end of the spring, which can be further fixed by welding or the like. In this way, reliable, stable and simple installation is achieved.

[0027] The second end of the conveying bin 20 protrudes from the fixed base 10. The discharging port 202 is a lower opening provided at the second end of the conveying bin 20, which is more convenient for the output of materials and the connection of other receiving devices. Of course, in other embodiments, the discharging port 202 can also be provided at the end of the second end of the conveying bin 20, i.e. the discharging port 202 is a lateral opening.

[0028] The conveying bin 20 comprises a silo 21 in a "U" shape in cross section and a cover plate 22 covering the upper opening of the silo 21, and the feeding port 201 is formed on the cover plate 22.

[0029] The number of the feeding ports 201 is multiple, three in the embodiment, and the three feeding ports 201 are arranged at intervals along the length direction of the conveying bin 20 for docking the three feeding ports of the incoming bin 1. Of course, in other embodiments, the number of the feeding ports 201 can also be one or more than two, which can be designed according to actual conditions.

[0030] The cover plate 22 is further provided with a visual window 203, and a transparent cover plate is covered on the visual window 203 for directly observing the conveying condition of the materials in the conveying bin 20. Specifically, the number of the visual windows 203 is multiple, and the visual windows 203 are arranged at intervals along the length direction of the conveying bin 20, so that the conveying conditions at various positions of the conveying bin 20 can be better observed to find problems more timely. More preferably, one of the visual windows 203 is arranged above the discharging port 202 to observe the discharging condition of the discharging port.

[0031] The inner wall of the conveying bin 20 is provided with a wear-resistant and corrosion-resistant plating layer or lining plate, which plays a role of wear resistance and corrosion resistance. Specifically, when the plating layer is adopted, the plating layer can adopt an ETFE (ethylene-tetrafluoroethylene copolymer) layer, a tungsten carbide coating or a ceramic adhesive layer, etc.; when the lining plate is adopted, an ETFE lining plate can be selected.

[0032] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all the changes are within the protection scope of the utility model.
