Description

Technical Field

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

[0002] Recycled concrete refers to new concrete made by crushing and cleaning discarded concrete blocks and then adding cement, water, etc. The production method of recycled concrete by crushing and reusing discarded concrete can reduce the demand for natural resources, reduce the generation of solid waste, and reduce carbon dioxide emissions. At the same time, the preparation process of recycled concrete is more energy-saving than traditional concrete, and there is no need to prepare new concrete materials from scratch. Recycled concrete is widely used in residential, commercial buildings, roads, bridges and other building structures.

[0003] In the preparation process of recycled concrete, loading is an important link. Its main function is to transport the processed recycled aggregate, cement, sand and other admixtures into the mixer in a certain proportion to provide the necessary raw materials for the subsequent mixing process.

[0004] At present, when feeding recycled concrete, there is a lack of a structure to remove dust from the raw materials, resulting in low purity and cleanliness of the recycled concrete. For this reason, we propose a feeding device for recycled concrete preparation. Utility Model Content

The vibration of the movable plate can drive the raw materials to shake, so that the light dust in the raw materials can be shaken up. The axial flow fan generates suction force, and cooperates with the dust hood to absorb and discharge the dust shaken up in the raw materials, thereby effectively improving the purity and cleanliness of the recycled concrete.

[0011] Specifically, one end of the rubber magnetic plate is connected to a connecting plate, and fastening bolts are provided at the corners around the connecting plate through bolt holes, and a handle No. 1 is provided on one side of the connecting plate.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] In order to improve the purity and cleanliness of recycled concrete, Figure 1-4As shown, a feeding device for preparing recycled concrete described in the utility model comprises a box body 1, a feeding channel 4 is arranged on one side of the top of the box body 1, a discharging channel 9 is arranged on one side of the bottom of the box body 1, a rubber magnetic plate 6 is installed inside the box body 1, and an oblique unloading plate 12 is arranged on the inner bottom of the box body 1;

[0030] A stepper motor 18 is installed on the other side of the box body 1 through a mounting seat 16, and the periphery of the output end of the stepper motor 18 is connected to a paddle 19. A movable plate 21 is provided inside the box body 1 at the upper end of the rubber magnetic plate 6, and one end of the movable plate 21 is connected to the inner wall of the box body 1 through a cylindrical rotating shaft 22. A mounting frame 23 is fixed on the top of the box body 1 on one side of the feed channel 4, and an axial flow fan 25 is installed inside the mounting frame 23 through a fixing rod 24. A dust hood 26 for easy dust collection is fixed on one side of the top of the box body 1.

[0031] When in use, when feeding, the rubber magnetic plate 6 is convenient for removing magnetic impurities such as iron nails, iron wires, iron sheets, etc. in the raw materials, so as to prevent the impurities from affecting the purity and cleanliness of the recycled concrete;

[0032] The inclined blanking plate 12 is an inclined structure, and is made of ceramic material, which has good wear resistance and smoothness, and is conducive to the sliding of the raw materials;

[0033] The rotation of the stepper motor 18 can drive the paddle 19 to rotate, and the paddle 19 can drive the movable plate 21 to shake. As the stepper motor 18 continues to rotate, the paddle 19 can continuously drive the movable plate 21. When the raw material falls onto the surface of the movable plate 21, the shaking of the movable plate 21 can drive the raw material to shake, so that the light dust in the raw material can be shaken up. The axial flow fan 25 cooperates with the dust hood 26 to absorb and discharge the dust shaken up in the raw material.

[0034] For example, Figure 1 , Figure 2 , Figure 3 As shown, one end of the rubber magnetic plate 6 is connected to a connecting plate 7 , and fastening bolts 13 are provided at the corners around the connecting plate 7 through bolt holes 11 , and a number one handle 3 is provided on one side of the connecting plate 7 .

[0035] When in use, through the connecting plate 7, the bolt holes 11 and the fastening bolts 13, personnel can fasten the rubber magnetic plate 6 inside the box body 1, and it is easy to disassemble.

[0036] For example, Figure 1 As shown, a side door 2 is installed at one end of the box body 1 through a hinge, and a second handle 8 is provided on one side of the side door 2.

[0037] When in use, by tightly gripping the second handle 8, a person can open the side door 2 for easy inspection.

[0038] For example, Figure 1 , Figure 3 As shown, a sealing plate 5 is installed inside the discharge channel 9 by opening a mounting groove 15 , and a No. 3 handle 10 is provided at one end of the sealing plate 5 .

[0039] When in use, a person can pull out the sealing plate 5 from the inside of the discharge channel 9 by tightly gripping the third handle 10 , thereby opening the discharge channel 9 .

[0040] For example, Figure 4 As shown, a first reserved opening 14 is provided on one side of the box body 1 , and a second reserved opening 20 is provided on the other side of the box body 1 .

[0041] When in use, the No. 1 reserved opening 14 facilitates the end of the rubber magnetic plate 6 to pass through the box body 1 and connect with the connecting plate 7, and the No. 2 reserved opening 20 facilitates the end of the movable plate 21 to pass through the box body 1 and fit with the dial plate 19, and the height of the No. 2 reserved opening 20 is greater than the thickness of the movable plate 21, which facilitates the movement of the movable plate 21.

[0042] For example, Figure 3 As shown, the top of the discharge channel 9 is provided with an end plug 17 through a sampling port, and the end plug 17 is made of silicone rubber material.

[0043] When in use, the end plug 17 made of silicone rubber material is soft in texture and has good fit, and can seal the sampling port on the box body 1 .

[0044] When the utility model is used, when feeding, the rubber magnetic plate 6 is convenient for removing magnetic impurities such as iron nails, iron wires, iron sheets, etc. in the raw materials, so as to prevent the impurities from affecting the purity and cleanliness of the recycled concrete;

[0045] The inclined blanking plate 12 is an inclined structure, and is made of ceramic material, which has good wear resistance and smoothness, and is conducive to the sliding of the raw materials;

[0046] The rotation of the stepper motor 18 can drive the paddle 19 to rotate. The paddle 19 fits with one end of the bottom of the movable plate 21, and can lift one end of the paddle 19, while the other end of the movable plate 21 is connected to the box body 1 through the cylindrical rotating shaft 22. Therefore, when one end of the movable plate 21 is subjected to force and moves, its other end can be rotated by the action of the cylindrical rotating shaft 22. As the stepper motor 18 continues to rotate, the paddle 19 can continuously lift the movable plate 21, thereby achieving the effect of driving the movable plate 21 to vibrate; when the raw material falls onto the surface of the movable plate 21, the shaking of the movable plate 21 can drive the raw material to shake, so that the light dust in the raw material can be shaken up, and at this time, the axial flow fan 25 in the mounting frame 23 generates a suction force, which cooperates with the dust hood 26 to absorb and discharge the dust shaken up in the raw material, thereby effectively improving the purity and cleanliness of the recycled concrete.
