AI Technical Summary
Technical Problem
The existing quantitative feeding equipment suffers from frequent maintenance and high procurement costs.
Method used
The system uses a combination of a screw feeder and a scraper. The screw feeder is used to transport sand and gravel aggregates to the quantitative bin, and the scraper is used to scrape off excess material. The opening and closing of the tilting plate is controlled by a cylinder to achieve quantitative feeding, and the capacity is adjusted by switching the bottom plate and the positioning block.
Benefits of technology
It achieves low-cost and reliable quantitative feeding, reduces maintenance frequency, and improves equipment applicability.

Abstract
This utility model relates to a quantitative feeding device for concrete aggregates. It includes a feeding hopper, a quantitative hopper, and a screw feeder. The quantitative hopper is defined by a front baffle, a left side plate, a right side plate, a rear baffle, a tilting plate, and a bottom plate. The bottom plate is inclined rearward, forming a discharge port between the bottom plate and the rear baffle. The upper end of the rear baffle has a rearwardly extending mounting plate, on which a cylinder is hinged. The extension end of the cylinder is hinged to the tilting plate; when the cylinder extends, it pushes the tilting plate to completely close the discharge port. The feeding device also includes a horizontal reciprocating mechanism and a scraper. The horizontal reciprocating mechanism drives the scraper to move horizontally back and forth on the upper side of the quantitative hopper. This utility model utilizes a screw feeder to transfer aggregates from the feeding hopper to the quantitative hopper, and then uses the reciprocating scraper to remove excess aggregates, achieving quantitative feeding with higher reliability and significantly reducing maintenance frequency.
