Description

Technical Field

[0001] The utility model relates to the technical field of equipment related to concrete preparation, in particular to a feeding device for preparing recycled concrete. Background Art

[0002] Recycled concrete refers to the new concrete made by crushing, cleaning and grading discarded concrete blocks, mixing them with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregate), and then adding cement, water, etc. Recycled concrete can be made into the following types of concrete according to the combination of aggregates: all aggregates are recycled aggregates; coarse aggregates are recycled aggregates and fine aggregates are natural sand; coarse aggregates are natural crushed stone or pebbles and fine aggregates are recycled aggregates; recycled aggregates replace part of coarse aggregates or fine aggregates.

[0003] The utility model patent entitled "A feeding device for preparing recycled concrete" (application number 202120590977.9) states that "the utility model discloses a feeding device for preparing recycled concrete, which relates to the technical field of concrete preparation equipment, including a working box, a cavity, a first movable block, an electric telescopic rod, a movable plate, a slider, a compression spring, a first servo motor, a first reciprocating screw, a water outlet, a water tank, a connecting pipe, a second servo motor, a second reciprocating screw, a second movable block, a connecting rod, a scraper, a rotating shaft, a crawler, an eccentric wheel and a third movable block. The utility model arranges a scraper, adjusts the angle of the movable plate, and evenly sprinkles water on the concrete through the third movable block. The scraper moves on the top of the movable plate to prevent the concrete from solidifying on the surface of the movable plate, thereby ensuring the working effect of the device. By arranging a crawler and an eccentric wheel, the movable plate vibrates up and down, and the concrete moves with the movable plate, further increasing the flow rate of the concrete and ensuring the working effect of the device." However, the utility model patent has the following problems:

[0004] 1. The application does not take into account the existence of a gap between the working box, the first movable block and the slider due to the sliding connection. This treatment method is not good because it will cause the material to penetrate into the gap, causing material loss and affecting the sliding properties between the components, ultimately affecting the normal use of the equipment, so it cannot achieve the best treatment effect;

[0005] 2. The application does not take into account that the position where the second reciprocating screw is set will come into contact with the material. After the material adheres to the threads of the second reciprocating screw and solidifies, the second reciprocating screw will lose its effect, ultimately affecting the normal use of the equipment and failing to achieve the best processing effect.
