Description

Technical Field

[0001] The utility model relates to an aggregate feeding device, in particular to a premixed concrete aggregate feeding device. Background Art

[0002] Concrete aggregate refers to granular loose materials that play a role of skeleton or filling in concrete. It is divided into coarse aggregate and fine aggregate. Coarse aggregate refers to pebbles, crushed stones, etc., and fine aggregate refers to natural sand, artificial sand, etc. The weight ratio of coarse aggregate in concrete is about 60%, which is an important part of concrete production.

[0003] When mixing concrete, different raw materials need to be put into the mixer in a certain order for mixing. The feeding timing and method of coarse aggregate determine the mixing quality of concrete. In the prior art, the feeding of coarse aggregate mostly adopts conveyor belt to transport to the mixer and then centralized feeding. The feeding position is uneven, which increases the mixing difficulty of the mixer and makes the mixing time long. Summary of the Utility Model

[0019] The utility model will be described in detail below with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0020] As Figures 1 to 4 In the embodiment of the precast concrete aggregate feeding device of the utility model shown, the precast concrete aggregate feeding device includes a mixer 1 with an upper opening. A spreading bin 2 is provided above the mixer 1. The spreading bin 2 is communicated with the upper opening of the mixer 1. A rotating spreading plate 3 is provided inside the spreading bin 2. A feeding bin 4 is provided at the top of the spreading bin 2. A feeding port 5 is opened on the side wall of the feeding bin 4.

[0021] Specifically, the coarse aggregate is transported to the feeding port 5 by a conveying device, fed into the feeding bin 4, and falls from the feeding bin 4 onto the spreading disk 3. The rotating spreading disk 3 uses centrifugal force to throw the coarse aggregate in all directions, and it collides with the inner wall of the spreading bin 2 and then falls into the mixer 1. Since the shape of the coarse aggregate is irregular, diffuse reflection occurs after colliding with the wall of the spreading bin 2, forming a uniform distribution in the mixer 1, enabling the coarse aggregate to spread out in the mixer 1, which is conducive to the mixer 1 mixing the coarse aggregate evenly. Compared with the fixed placement position of the coarse aggregate, it takes less time to make the concrete evenly mixed, and the mixing difficulty of the mixer is reduced due to the uniform distribution of the coarse aggregate.

[0022] In an embodiment of the present application, preferably, a rotating shaft 6 is fixedly connected to the center of the spreading disk 3. The rotating shaft 6 is rotatably connected to the top of the feeding bin 4. A spreading motor 7 is fixedly connected to the top of the feeding bin 4. The drive shaft of the spreading motor 7 is fixedly connected to the rotating shaft 6 for driving the spreading disk 3 to rotate.

[0023] In an embodiment of the present application, preferably, there are a plurality of radially arranged ribs 8 on the spreading disk 3. The ribs 8 are respectively fixedly connected to the spreading disk 3 and the rotating shaft 6. The ribs 8 are used to prevent the coarse aggregate from slipping on the spreading disk 3.

[0024] In an embodiment of the present application, preferably, the rib 8 is arc-shaped, and the arc top direction of the arc-shaped rib 8 is consistent with the rotation direction of the spreading disk 3, making the spreading of the coarse aggregate more uniform.

[0025] In an embodiment of the present application, preferably, a receiving disk 9 is fixedly connected to the feeding port 5 for docking with the coarse aggregate conveying device.

[0026] In an embodiment of the present application, preferably, a lining plate 10 is fixedly connected to the wall of the spreading bin 2, which is used to reduce the wear of the coarse aggregate on the bin wall, extend the service life of the equipment, and also increase the roughness of the bin wall.

[0027] In an embodiment of the present application, preferably, two stirring shafts 11 are rotatably connected in the mixer 1. Stirring spiral belts 12 are fixedly connected to the stirring shafts 11. A stirring motor 13 is fixedly connected to the mixer 1. The drive shaft of the stirring motor 13 is fixedly connected to the stirring shaft 11 for making the stirring faster and more uniform, and the production efficiency is higher.

[0028] In summary, for the premixed concrete aggregate feeding device in the above embodiments of the present utility model, specifically, the coarse aggregate is transported to the receiving tray 9 by the conveying device, fed into the feeding bin 4 through the feeding port 5, and falls from the feeding bin 4 onto the spreading tray 3. The spreading motor 7 is started, and the rotating spreading tray 3 uses centrifugal force to throw the coarse aggregate around, colliding with the inner wall of the spreading bin 2 and falling into the mixer 1. Since the shape of the coarse aggregate is irregular, diffuse reflection occurs after colliding with the wall of the spreading bin 2, forming a uniform distribution in the mixer 1, causing the coarse aggregate to disperse in the mixer 1. Compared with the fixed placement position of the coarse aggregate, it can make the concrete mixing more uniform and take less time. Since the coarse aggregate is evenly distributed, the mixing difficulty of the mixer is reduced.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
