Detailed Description of the Embodiment

[0026] The following will further elaborate on the present application Figures 1-4 with reference to the attached drawings.

[0027] The embodiment of the present application discloses a material conveying device for concrete production. Referring to Figures 1-4 , a material conveying device for concrete production includes a conveying frame 1. A support 2 is fixed at the bottom end of the conveying frame 1. A conveyor belt 3 is drivingly connected to the top end of the conveying frame 1. A first driving motor 4 for driving the movement of the conveyor belt 3 is fixed on one side of the conveying frame 1. A guide plate 5 is fixed at the blanking end of the conveying frame 1. The bottom end of the guide plate 5 is rotatably connected to a blanking plate 6. The blanking plate 6 is connected to the support 2 through a swinging component 7. A reciprocating component 8 for driving the movement of the swinging component 7 is provided on one side of the support 2.

[0028] In this embodiment, a plurality of conveyor rollers are rotatably connected to the conveyor frame 1, and the plurality of conveyor rollers are drivingly connected by a conveyor belt 3. The first drive motor 4 is fixedly connected to one of the conveyor rollers. Thus, when the first drive motor 4 drives the conveyor roller to rotate, the conveyor belt 3 can be driven to rotate to convey the concrete raw materials. After the concrete raw materials are conveyed to the guide plate 5 by the conveyor belt 3, they are then conveyed to the blanking plate 6, and then under the movement of the reciprocating assembly 8, the movement of the swinging assembly 7 is driven. The swinging assembly 7 drives the swinging of the blanking plate 6 to adjust the end position of the blanking plate 6, so that the concrete raw materials can be blanked at different positions, avoiding the accumulation of the concrete raw materials, facilitating the mixing of the concrete raw materials, and improving the mixing efficiency of the concrete raw materials.

[0029] In a further embodiment, as Figure 2 shown, the swinging assembly 7 includes a connecting rod 71 hinged to the bottom end of the blanking plate 6. One end of the connecting rod 71 is hinged with a slider 72. A sliding groove 73 for the slider 72 to slide is formed on one side of the support 2. The reciprocating assembly 8 includes two rotating wheels 81 rotatably arranged on one side of the support 2. The two rotating wheels 81 are drivingly connected by a chain 82. One side of the chain 82 is hinged with a pull rod 83 hinged to the slider 72. A second drive motor 84 fixed to the rotating wheel 81 is fixed on one side of the support 2.

[0030] After the conveyor belt 3 conveys the concrete raw materials to the guide plate 5, they then slide down to the blanking plate 6 through the guide plate 5. Then, under the movement of the second drive motor 84, the rotation of the rotating wheel 81 is driven. The rotating wheel 81 drives the rotation of the chain 82. The chain 82 drives the movement of the pull rod 83. The pull rod 83 drives the reciprocating movement of the slider 72. The slider 72 drives the reciprocating movement of the connecting rod 71, thereby driving the reciprocating swing of the blanking plate 6. During the swinging of the blanking plate 6, the position of its end continuously changes, so that it is convenient to blank the concrete raw materials at different positions, avoiding the accumulation of the concrete raw materials, facilitating the mixing of the concrete raw materials, and improving the mixing efficiency of the concrete raw materials.

[0031] In a further preferred embodiment of the present utility model, as Figure 1 shown, a support plate 9 is fixed to the feeding end of the conveyor frame 1. A feed hopper 10 is fixed to the top end of the support plate 9. A blanking port 11 located above the conveyor belt 3 is formed at the bottom end of the feed hopper 10. Guide plates 12 are inclined and fixed on both sides of the inner wall of the feed hopper 10. A crushing assembly 13 is arranged below the guide plates 12.

[0032] When transporting concrete raw materials, first pour the concrete raw materials into the feed box 10. The concrete raw materials fall onto the crushing assembly 13 through the guide plate 12. The crushing assembly 13 crushes the concrete raw materials with relatively large volumes. After crushing, they fall onto the conveyor belt 3 through the discharge opening 11 for transportation. This facilitates the crushing of the concrete raw materials with relatively large volumes, is conducive to the mixing of concrete raw materials, and improves the mixing efficiency of concrete raw materials.

[0033] In a further embodiment, as Figures 3-4 shown, the crushing assembly 13 includes two crushing rollers 131 rotatably arranged in the feed box 10 below the guide plate 12. One end of each of the two crushing rollers 131 is fixed with a meshing gear 132. The gear 132 is connected to the first driving motor 4 through a linkage assembly 14. The linkage assembly 14 includes a driving wheel 141 sleeved on the output shaft of the first driving motor 4. One side of the gear 132 is fixed with a driven wheel 142. The driving wheel 141 is in transmission connection with the driven wheel 142 through a belt 143.

[0034] When transporting concrete raw materials, first turn on the first driving motor 4 to drive the conveyor belt 3 to rotate. At the same time, the first driving motor 4 drives the driving wheel 141 to rotate. The driving wheel 141 drives the driven wheel 142 to rotate. The driven wheel 142 drives the two meshing gears 132 to rotate, thereby driving the two crushing rollers 131 to rotate in opposite directions. Then pour the concrete raw materials into the feed box 10 and let them slide down to the crushing rollers 131 through the guide plate 12. The crushing rollers 131 can then crush the concrete raw materials with relatively large volumes. After crushing, they fall onto the conveyor belt 3 through the discharge opening 11 for transportation. This facilitates the crushing of the concrete raw materials with relatively large volumes, is conducive to the mixing of concrete raw materials, and improves the mixing efficiency of concrete raw materials.

[0035] The implementation principle of a material conveying device for concrete production in an embodiment of the present application is as follows: When conveying concrete raw materials, first turn on the first driving motor 4, so that the first driving motor 4 drives the conveyor belt 3 to rotate. At the same time, the first driving motor 4 drives the driving wheel 141 to rotate, the driving wheel 141 drives the driven wheel 142 to rotate, and the driven wheel 142 drives two meshing gears 132 to rotate, thereby driving two crushing rollers 131 to rotate in opposite directions. Then pour the concrete raw materials into the material box 10, and let them slide down to the crushing rollers 131 through the guide plate 12. The larger-sized concrete raw materials can be crushed by the crushing rollers 131. After crushing, they fall onto the conveyor belt 3 through the discharge opening 11 for conveying. This facilitates the crushing of larger-sized concrete raw materials, is conducive to the mixing of concrete raw materials, and improves the mixing efficiency of concrete raw materials. When the concrete raw materials are conveyed onto the guide plate 5, they then slide onto the discharge plate 6. Then, under the movement of the second driving motor 84, the rotation of the rotating wheel 81 is driven. The rotating wheel 81 drives the rotation of the chain 82, and the chain 82 drives the movement of the pull rod 83. The pull rod 83 drives the reciprocating movement of the slider 72, and the slider 72 drives the reciprocating movement of the connecting rod 71, thereby driving the reciprocating swing of the discharge plate 6. During the swinging process of the discharge plate 6, the position of its end constantly changes, which facilitates the discharging of concrete raw materials at different positions, avoids the accumulation of concrete raw materials, is conducive to the mixing of concrete raw materials, and improves the mixing efficiency of concrete raw materials.

[0036] The above are all the preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
