Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to an ore quantitative feeding buffer transfer device. Background Art

[0002] In the past, due to the limited height inside the corridor of the mining dam, when the vibrating feeder is in the working state, the material rolls into the vibrating feeder through the bin opening. Most of the material directly hits the vibrating feeder, causing direct damage to the vibrating feeder, affecting the service life of the vibrating feeder, and increasing the production and maintenance costs. When the material is in the non-operating state and the angle of repose of the material is greater than the angle of repose, the material will automatically roll into the bin opening until the bin opening, the feed hopper, the vibrating feeder, and the discharge hopper are full of the material, resulting in an increase in the pressure on the vibrating feeder and also causing direct damage to the belt conveyor, affecting the service life of the equipment.

[0003] Therefore, there is an urgent need for a technical solution to solve the above problems. Summary of the Utility Model

An adjusting plate is arranged above the inlet opening, and the adjusting plate covers a part of the feeding working surface of the inlet opening to control the area of the material falling on the vibrating feeding plate.

[0008] By arranging a buffer plate in front of the feed hopper, it plays a buffering role for the material falling at the inlet opening, thereby reducing the direct damage caused by the material to the vibrating feeder. By arranging an adjusting plate above the inlet opening, the feeding amount of the material at the inlet opening is controlled. Cooperating with the buffer plate, it can control the area of the material directly pressing on the vibrating feeder within one-fourth of the bin opening area, meeting the design requirements of the vibrating feeder without affecting the material feeding space and flow angle.

[0009] After controlling the feeding amount of the material at the feeding port by using the regulating plate, the area where the material directly presses on the vibrating feeder can be reduced, thereby reducing the bin pressure of the material in the feeding hopper.
