[0021] In this embodiment, the supporting plate 5 includes a hard metal base 51 and a nylon lining plate 52, wherein the nylon lining plate 52 is a plate-like structure with a rectangular cross-section, and a plurality of nylon lining plates 52 are respectively wrapped around the outer surface of the upper end surface of the hard metal base 51, and the nylon lining plates 52 are spirally structured around the axis of the hard metal base 51, and the lower end surface of the hard metal base 51 is respectively connected to the supporting spring 4 and the exciter 6.

[0022] By arranging the nylon lining plates in a spiral structure, a spiral joint is formed between adjacent nylon lining plates, and the joint can be used to guide material transportation.

[0023] In this embodiment, the load-bearing column 3 is a telescopic column structure of at least two stages, and the upper end surface of the load-bearing column 3 is coaxially distributed with the assembly groove 7, the lower half of the load-bearing spring 4 is embedded in the assembly groove 7, and is connected to the bottom of the assembly groove 7 through the pressure sensor 8, and at the same time, 20%-60% of the effective length of the load-bearing spring 4 is embedded in the assembly groove 7 and is slidably connected to the wall of the assembly groove 7.

[0024] By setting the supporting column as a telescopic column structure, on the one hand, the height of the supporting plate can be flexibly adjusted to effectively meet the thickness of the material layer during material transportation; on the other hand, the height of the supporting plate can be adjusted locally through the supporting column so that the upper end surface of the supporting plate is at a certain angle to the horizontal plane, thereby achieving rapid cleaning operations.

[0025] It should be emphasized that the hard metal base 51 includes a bearing base 511, a bearing plate 512, a connecting pipe head 513, and an exhaust port 514. Among them, the bearing base 511 is a cylindrical groove structure with a "U"-shaped axial cross-section. Its upper end surface is connected to the lower end surface of the bearing plate 512 and is coaxially distributed. The diameter of the bearing plate 512 is at least 1.5 times the diameter of the upper end surface of the bearing base 511. At the same time, the lower end surface of the bearing base 511 is respectively connected to the bearing spring 4 and the vibrator 6.

[0026] The provided connecting pipe head, exhaust port, and exhaust gap can transport the external high-pressure air flow to the upper end surface of the bearing plate through the exhaust gap, so as to form a stable air flow driving layer between the upper end surface of the bearing plate and the surface of the material it bears. On the one hand, it enables the material to quickly achieve driving flow under the drive of the air flow, improving the feeding operation efficiency; on the other hand, through the air cushion layer formed by the air flow, the frictional loss between the flowing material and the surface of the bearing plate is effectively reduced, improving the service life of the bearing plate.

The side surfaces of the nylon plate corresponding to the front and rear end surfaces of the ceramic pads 521 form an angle of 100° - 135° with the lower part of the nylon plate, and this inclined side surface corresponds to the position of the exhaust gap 515.

[0030] Meanwhile, among the nylon lining plates 52 , the upper end surfaces of the nylon lining plates 52 are evenly distributed, and the upper end surfaces of the nylon lining plates 52 are parallel to the upper end surface of the carrier plate 5 or inclined.

[0031] It should be noted that when the upper end surface of the nylon lining plate 52 adopts an inclined structure with the upper end surface of the carrying plate 5, the upper end surface of the nylon lining plate 52 adopts any one of a truncated cone structure and a spherical cap structure, and the upper end surface of the nylon lining plate 52 at the center position of the carrying plate 5 is 1-10 mm higher than the upper end surface of the nylon lining plate 52 at the edge position of the carrying plate.

[0032] By maintaining a certain inclination angle between the upper end surface of the nylon lining plate and the upper end surface of the carrying plate, the material conveying efficiency is assisted to be improved.

[0033] During operation of the present invention, the base support, toothed disc, bearing column, bearing spring, bearing disc and vibrator constituting the present invention are first assembled, and then the base support is connected to the frame mechanism of the disc feeder, and the toothed disc is connected to the power mechanism of the disc feeder to complete the assembly of the present invention.

[0034] During operation, the carrier plate of the present invention is driven by the disc feeder to run and convey materials. On the one hand, the material can be kept in an oscillating state on the carrier plate by means of the provided load-bearing spring and vibrator, thereby improving the material conveying efficiency and preventing blockage and other faults caused by material accumulation. On the other hand, the provided nylon lining plate can effectively protect the metal structure of the carrier plate, reduce the wear of the technical components by the material, and can quickly replace the local nylon lining plate during equipment maintenance, thereby improving the equipment operation stability and reducing the equipment operation and maintenance costs.

[0035] The utility model has a simple structure and good versatility, and can be effectively used in conjunction with existing equipment. During operation, on the one hand, it can effectively improve the wear resistance; on the other hand, it can effectively improve the work efficiency of material conveying operations, thereby effectively improving the material conveying operation efficiency and the stability and continuity of equipment operation, and helping to reduce equipment operation and maintenance costs.
