Detailed Embodiments

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative work shall fall within the protection scope of the present application.

[0028] Please refer to Figure 1 , Figure 2 andFigure 3 , in the feeding device of the concrete mixing tank in this embodiment, it includes a moving mechanism 1. The moving mechanism 1 includes a bottom plate 11, and casters 12 are fixedly installed at the four corners of the bottom of the bottom plate 11. A receiving mechanism 2 is arranged on the top of the moving mechanism 1, a weighing mechanism 3 is arranged inside the receiving mechanism 2, a shoveling mechanism 4 located outside the receiving mechanism 2 is arranged on the top of the moving mechanism 1, a quantitative mechanism 5 is arranged at the bottom of the shoveling mechanism 4, and a transporting mechanism 6 is arranged on the right side of the receiving mechanism 2.

[0029] Specifically, moving the bottom plate 11 enables the casters 12 to drive the whole feeding device to be easily displaced to the raw material stacking place. Then, start the shoveling mechanism 4 to shovel the raw materials. Subsequently, start the quantitative mechanism 5 so that the raw materials can enter the weighing mechanism 3 for weighing and be sent into the transporting mechanism 6. The excess raw materials can be returned to the raw material stacking place again through the quantitative mechanism 5, significantly saving labor costs.

[0030] Please refer to Figure 1 , the receiving mechanism 2 includes a receiving bin 21. The receiving bin 21 is fixedly installed on the top of the bottom plate 11. A transport hole 22 that penetrates through one end and extends into the inside of the receiving bin 21 is opened on the right side of the receiving bin 21, and a feeding hole 23 that penetrates through one end and extends into the inside of the receiving bin 21 is opened on the top of the receiving bin 21.

[0031] Specifically, the setting of the feeding hole 23 facilitates the entry of raw materials into the receiving bin 21, and the setting of the transport hole 22 facilitates the removal of raw materials from the inside of the receiving bin 21.

[0032] Please refer to Figure 1 and Figure 2 , the weighing mechanism 3 includes a brushless motor 31, a weighing bin 32, and an electronic scale 33. The brushless motor 31 is fixedly installed on the left side of the receiving bin 21. The output end of the brushless motor 31 is fixedly installed with a weighing bin 32. The weighing bin 32 penetrates through and extends into the inside of the receiving bin 21. The right side of the weighing bin 32 is rotatably connected to the right inner wall of the receiving bin 21. An electronic scale 33 is fixedly installed on the inner bottom wall of the weighing bin 32. The weighing bin 32 is rotatably connected to the receiving bin 21 through a bearing.

[0033] Specifically, starting the brushless motor 31 to make the weighing bin 32 flip can easily make the raw materials fall into the transporting mechanism 6 for transportation.

[0034] It should be noted that the setting of the electronic scale 33 facilitates the weighing of raw materials and can quickly start the quantitative mechanism 5 so that the excess raw materials can leak out.

[0035] Please refer to Figure 3, the shoveling mechanism 4 includes a transport shovel 41. Driving rods 42 are fixedly installed on both the front and rear sides of the transport shovel 41. A reduction motor 43 is fixedly installed on the top of the bottom plate 11 and on the front side of the receiving bin 21. The output end of the reduction motor 43 is fixedly connected to the front driving rod 42, and the rear driving rod 42 is rotatably connected to the back surface of the receiving bin 21.

[0036] Specifically, start the reduction motor 43 to drive the front driving rod 42 to rotate the transport shovel 41 to the left, and make the transport shovel 41 contact the ground. At this time, the transport shovel 41 enters the raw materials. Then start the reduction motor 43 to restore the transport shovel 41 by driving the front driving rod 42. In this way, the raw materials can be quantitatively transported through the metering mechanism 5.

[0037] Please refer to Figure 1 , Figure 2 and Figure 4 , the metering mechanism 5 includes a discharge pipe 51. A control valve 52 is fixedly installed on the outside of the discharge pipe 51. A servo motor 53 is fixedly installed on the outside of the discharge pipe 51 and below the control valve 52. The output end of the servo motor 53 is fixedly installed with a rotating shaft 54. The rotating shaft 54 penetrates and extends into the discharge pipe 51. The back surface of the rotating shaft 54 is rotatably connected to the discharge pipe 51. A flow dividing plate 55 is fixedly installed on the outside of the rotating shaft 54. The rotating shaft 54 is rotatably connected to the discharge pipe 51 through a bearing. The outer wall of the flow dividing plate 55 is in contact with the inner wall of the discharge pipe 51. Both the left and right sides of the discharge pipe 51 are communicated with a distributing pipe 56. The two distributing pipes 56 are respectively located on the left and right sides of the flow dividing plate 55.

[0038] Specifically, start the servo motor 53 to drive the rotating shaft 54 to rotate the flow dividing plate 55 to the left, so that the upper left side of the flow dividing plate 55 contacts the left inner wall of the discharge pipe 51, and the lower right side of the flow dividing plate 55 contacts the right inner wall of the discharge pipe 51. Then open the control valve 52, and the raw materials can enter the weighing mechanism 3 through the right distributing pipe 56. Then, start the servo motor 53 again to drive the rotating shaft 54 to restore the flow dividing plate 55, and the raw materials can be discharged.

[0039] Please refer to Figure 1 , the transport mechanism 6 includes a transport pipe 61. The transport pipe 61 is fixedly installed on the right side of the receiving bin 21. The transport pipe 61 is located outside the transport hole 22. The bottom of the transport pipe 61 is fixedly connected to the top of the bottom plate 11. A baffle belt conveyor 62 with one end extending into the receiving bin 21 is fixedly installed inside the transport pipe 61.

[0040] Specifically, start the weighing mechanism 3, and the raw materials can be transported into the mixing tank through the baffle belt conveyor 62.

[0041] It should be noted that the setting of the transport pipe 61 effectively prevents the raw materials from leaking from the front and rear sides of the baffle belt conveyor 62.

[0042] The working principle of the above embodiments is as follows:

[0043] During use, by moving the bottom plate 11, the casters 12 drive the entire feeding device to be displaced to the raw material stacking place. At the same time, the reduction motor 43 is started, which drives the front driving rod 42 to drive the transport shovel 41 to rotate to the left, and the transport shovel 41 contacts the ground. At this time, the transport shovel 41 enters the raw materials. Then, the reduction motor 43 is started to restore the transport shovel 41 via the front driving rod 42. Next, the servo motor 53 is started to drive the rotating shaft 54 to drive the diverter plate 55 to rotate to the left, so that the upper left side of the diverter plate 55 contacts the inner wall of the left side of the discharge pipe 51, and the lower right side of the diverter plate 55 contacts the inner wall of the right side of the discharge pipe 51. Then, the control valve 52 is opened, and the raw materials can enter the inside of the weighing bin 32 through the right side material distribution pipe 56. At this time, the electronic scale 33 weighs the raw materials. When the weight of the raw materials reaches the specified weight, the data is transmitted to the control terminal, and the control terminal will close the control valve 52 and start the servo motor 53 to drive the rotating shaft 54 to restore the diverter plate 55. At this time, the brushless motor 31 flips the weighing bin 32, and then transports the raw materials into the mixing tank through the baffle belt conveyor 62. In this way, the excess raw materials will be discharged to the raw material stacking place through the left side material distribution pipe 56, minimizing manual weighing and feeding, significantly improving the feeding efficiency, and accelerating the concrete production rate.
