Description

Technical Field

[0001] This utility model relates to the field of cement conveying technology, and more specifically, to a feeding device for concrete production. Background Technology

[0002] A concrete mixing plant is an industrial facility used for centralized concrete production. It mainly consists of a raw material storage system, a metering system, a mixing system, a control system, and a conveying system. It can mix cement, aggregates (such as sand and stone), water, and admixtures in a certain proportion to produce concrete that meets engineering requirements. It has advantages such as high-efficiency production, stable quality, environmental protection, and energy saving.

[0003] There are two main methods of cement transportation: bulk cement transport and bagged cement transport. Bulk cement is typically transported by rail or road, suitable for large-scale engineering projects. General cement mixing plants primarily handle bagged cement. Within the mixing plant, cement is usually transported to the mixer using bucket elevators, belt conveyors, screw conveyors, etc. However, this process requires manual cutting of the bagged cement for transfer, which is wasteful of labor and poses health risks.

[0041] The following embodiments will be used to describe in detail a concrete feeding device for concrete production according to this application.

[0042] In this embodiment, as Figures 1 to 3 As shown, the concrete production feeding device includes: a conveying mechanism 1, which is inclined;

[0043] Box 2 is hollow and has a discharge hole;

[0044] The rotating mechanism 3 is installed inside the box 2. The conveying mechanism 1 is used to convey bagged cement to the rotating mechanism 3, and the rotating mechanism 3 is used to drive the bagged cement to rotate.

[0045] Cutting mechanism 4, located inside box 2, is used to cut the packaging bags of bagged cement;

[0046] Rotating mechanism 3 includes:

[0047] The first drive motor 301 is mounted on the housing 2;

[0048] The rotating shaft 302 is connected to the first drive motor 301 and has a shaft protrusion 305;

[0049] The first guide rail 303 is circular and is fixedly installed inside the housing 2;

[0050] Several support members 304 are evenly arranged between the shaft protrusion 305 and the first guide rail 303. One end of each support member 304 is connected to the shaft protrusion 305, and the other end of each support member 304 is engaged with the first guide rail 303. The first drive motor 301 is used to drive each support member 304 to rotate.

[0051] In this technical solution, the bottom of the box 2 is inclined to the lower right, and the discharge hole of the box 2 is located at the intersection of its right side and bottom side. The conveying mechanism 1 is a belt conveyor or a bucket elevator, which is arranged on the left side of the box 2 in the direction from the lower left to the upper right. The left side wall of the box 2 is provided with a clearance hole for the conveying mechanism 1 to pass through, and the right end of the conveying mechanism 1 extends above the area on the left side of the first guide rail 303.

[0052] The rotating mechanism 3 is located inside the housing 2. The first drive motor 301 is fixed to the upper side of the housing 2. The rotating shaft 302 is vertically installed inside the housing 2. The axle protrusion 305 is a circular plate-shaped component installed on the rotating shaft 302. The first guide rail 303 is coplanar with the axle protrusion 305 and surrounds the outside of the axle protrusion 305. The axle protrusion 305 has several notches, and pins are fixed in the notches. The inner end of the support member 304 is hinged to the pin at the notch, and the outer end of the support member 304 is engaged in the guide groove 306 of the first guide rail 303. The guide groove 306 also prevents the support member 304 from falling off the first guide rail 303. When the first drive motor 301 is turned on, the rotating shaft 302, the axle protrusion 305, and each support member 304 are rotated, which can transport the bagged cement conveyed by the left conveying mechanism 1 to the right side.

[0053] The cutting mechanism 4 is a motor-driven cutter, which is located on the right side of the rotating mechanism 3. The height of the cutter is between the first guide rail 303 and the first section 504, which can slide the packaging bag of cement.
