The first transmission mechanism 1 is connected to a first reduction motor 17, and the second transmission mechanism 2 is connected to a second reduction motor 20. When the first reduction motor 17 and the second reduction motor 20 are in operation, all the feeding devices can be operated simultaneously under the transmission action of the first transmission mechanism 1 and the second transmission mechanism 2, thereby realizing large-flow feeding and providing support for subsequent assembly line operations.

[0029] Specifically, the feeding device includes a feeding bin 3 and a feeding pipe 4. The feeding bin 3 transports the material vertically, and the feeding pipe 4 transports the material horizontally to realize the unloading function. The bottom of the feeding bin 3 is provided with a bin bottom plate 5, and the bin bottom plate 5 is provided with a discharge port 6 deviated from its center. The top and bottom of the feeding bin 3 are both open structures. The bin bottom plate 5 closes the bottom opening of the feeding bin 3, and the material inside the feeding bin 3 is discharged through the discharge port 6. A scraping mechanism 7 is provided inside the feeding bin 3, and the scraping mechanism 7 is used to intermittently sweep the discharge port 6 to discharge the material from the discharge port 6, prevent the material from being blocked at the discharge port 6, and avoid the phenomenon that the material at the bottom of the feeding bin 3 is compacted and agglomerated.

[0030] Among them, the scraping mechanisms 7 of two adjacent feeding devices are connected through the first transmission mechanism 1. Under the driving action of the first reduction motor 17, the scraping mechanisms 7 of the two feeding devices are driven by the first transmission mechanism 1 to operate simultaneously, so that the feeding bins 3 of the two feeding devices output materials at the same time. It is currently explained that for multiple feeding devices, a corresponding number of first transmission mechanisms 1 can be set, and the scraping mechanisms 7 of multiple feeding devices can be operated simultaneously by using the first transmission mechanism 1.

The conveying mechanisms of two adjacent feeding devices are connected through the second transmission mechanism 2.

[0033] Under the driving action of the second reduction motor 20, the conveying mechanisms of the two feeding devices are driven to operate simultaneously through the second transmission mechanism 2, so that the feeding pipes 4 of the two feeding devices output materials simultaneously. It is currently explained that for multiple feeding devices, a corresponding number of second transmission mechanisms 2 can be set, and the conveying mechanisms of multiple feeding devices can be operated simultaneously by using the second transmission mechanism 2, which can meet the demand for a large amount of material supply.

[0034] The present invention sets a first transmission mechanism 1 and a second transmission mechanism 2 between two adjacent feeding devices, uses the first transmission mechanism 1 to drive each scraping mechanism 7 to operate simultaneously, and uses the second transmission mechanism 2 to drive each conveying mechanism to operate simultaneously, so as to realize a large number of material output functions. The present invention can effectively reduce the number of driving devices, which can reduce the overall footprint of the equipment, reduce production energy consumption, and reduce the production cost of the product. Moreover, the overall structure is simple, which can greatly improve the working efficiency of feeding and provide strong support for subsequent assembly line operations.

In the case of three or more feeding devices, a part of the pulleys can be omitted, and two wheel grooves are set for the pulley located in the middle, and the two wheel grooves are connected to two first transmission belts 11. Taking three feeding devices as an example, only three pulleys need to be set, and the three pulleys are two first pulleys A9 and one first pulley B10, respectively. The first pulley B10 is located between the two first pulleys A9, and the first pulley B10 is set with two wheel grooves, and the two wheel grooves are respectively connected to a first transmission belt 11 between the two first pulleys A9, so as to realize the rotation of all the pulleys, so that the pulleys drive each scraping mechanism 7 to operate.

The second pulley A12 and the second pulley B13 are respectively connected to two conveying mechanisms, and the second pulley A12 and the second pulley B13 are connected through the second transmission belt 14. For the case of three or more feeding devices, a part of the pulleys can be omitted, and two wheel grooves are set for the pulley located in the middle, and the two wheel grooves are connected to two second transmission belts 14. Taking three feeding devices as an example, only three pulleys need to be set, and the three pulleys are two second pulleys A12 and one second pulley B13, respectively. The second pulley B13 is located between the two second pulleys A12, and the second pulley B13 is provided with two wheel grooves.

A first reduction motor 17 is connected to the end of the drive shaft 15 of one of the feeding devices. The scraper bar 16 is installed on the drive shaft 15. When the first reduction motor 17 drives the drive shaft 15 to rotate, the scraper bar 16 rotates on the surface of the silo bottom plate 5. The scraper bar 16 intermittently sweeps across the blanking port 6, so that the material in the feeding silo 3 is discharged from the blanking port 6, and can effectively prevent the material from being blocked at the blanking port 6.

[0040] The side wall of the feeding bin 3 is provided with an opening, and the feeding bins 3 of two adjacent feeding devices are connected to each other through the opening. Since the feeding bins 3 are connected, the material replenishment of all the feeding bins 3 can be achieved by only replenishing the material in one feeding bin 3.

[0041] In a specific embodiment, three feeding devices are arranged side by side. The three feeding devices are arranged on a frame 21, and the feeding bins 3 of the three feeding devices are interconnected.
