Description

Technical Field

[0001] The utility model belongs to the technical field of feeders, and in particular relates to a double-channel vibrating feeder. Background Art

[0002] Vibrating feeders are widely used in metallurgy, coal mining, mineral processing, building materials, chemical industry, agriculture and other industries due to their uniform, quantitative and continuous feeding, low working noise and simple structure. However, the single feeding mode sets great limitations for vibrating feeders, and the use of multiple vibrating feeders will cause problems such as space occupation. At the same time, the lack of material monitoring will cause the vibrating feeder to be in working state when there is no material, and the material conveying status cannot be directly reflected to the on-site staff, affecting the efficiency of the production line. Summary of the invention

[0003] The utility model aims to provide a dual-channel vibrating feeder to solve the problems of the existing vibrating feeder, such as single feeding mode and lack of material monitoring.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: a dual-channel vibrating feeder, including a frame, a screen frame structure, an oscillation component, a vibration reduction device, a photoelectric detection device and a discharge port; wherein,

[0005] The frame is a rectangular frame structure, consisting of four columns and a connecting rod horizontally fixed between two adjacent columns; a vibration reduction device is installed on the top of each of the four columns;

[0006] The screen frame structure consists of a bottom plate, two side plates, a tail plate and a partition plate; the bottom plate is a rectangular structure, the two side plates are symmetrically fixed on the bottom plate, the tail plate is fixed at one end of the bottom plate and connects the two side plates, the partition plate is fixed on the bottom plate and is parallel to the two side plates; two angle brackets are fixedly connected to the outer sides of the two side plates, and the positions of the angle brackets correspond to the four columns on the frame; the screen frame structure is connected to four vibration damping devices through four angle brackets; the discharge port is set at the end of the screen frame structure away from the tail plate;

[0007] The oscillation assembly includes a motor mounting plate, a vibration motor fixed on the motor mounting plate, and a connecting beam; two motor mounting plates are provided, both of which are fixed on the screen frame structure, and the two motor mounting plates are connected by a connecting beam;

[0008] Photoelectric detection devices are symmetrically arranged on two side plates of the screen frame structure, and the photoelectric detection devices are connected with the vibration motor signal.

[0009] Preferably, the discharge port is composed of two independent discharge troughs, both of which are arranged to be inclined downward, and a certain angle is formed between the two discharge troughs.

[0010] Preferably, the two motor mounting plates are respectively fixed on the two side plates of the screen frame structure, and the two motor mounting plates are symmetrically arranged.

[0011] Preferably, an audible and visual alarm is provided on the rack, and the audible and visual alarm is signal-connected to the photoelectric detection device.

[0012] Preferably, a vibration-damping base plate is installed between the column and the vibration-damping device.

[0013] Preferably, the number of connecting rods horizontally fixed between two adjacent columns is 2-4.

[0014] The utility model has a simple structure and is easy to use. By arranging two rows of parallel channels on the same screen frame structure and two independent discharge troughs at the discharge port, two materials are respectively allowed to enter the two channels in the screen frame, thereby completing the vibration conveying and discharge of the two materials. When the screen frame materials in any channel are accumulated and submerged in the sensing switch of the photoelectric detection device, the vibration frequency of the vibration motor increases. If the materials in the screen frame submerge in the sensing switch of the photoelectric detection device for a long time, the sound and light alarm is used to warn the on-site personnel, thereby avoiding the occurrence of material accumulation and blockage, thereby improving the efficiency of the production line.
