Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0021] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0022] Example:
[0023] Refer to the attached Figure 1 and Figure 2 The embodiment of the present invention is a machine-made sand aggregate proportioning and feeding device, comprising a mixing barrel 1, with bulk barrels 2 provided on both sides of the top of the mixing barrel 1. The bottoms of the mixing barrel 1 and the bottoms of the bulk barrel 2 are both conical structures. The design of the conical structure is conducive to the smooth falling of materials and reduces residues.
[0024] Refer to the attached Figure 1 and Figure 2 , a No. 1 stirring rod 4 is provided in the mixing barrel 1, and the No. 1 stirring rod 4 directly stirs the material in the mixing barrel 1 to ensure uniform mixing. The bottom of the mixing barrel 1 is connected with a discharge pipe 15, and the mixed material is discharged from the discharge pipe 15. A No. 2 stirring rod 5 is provided in the bulk barrel 2, and the No. 2 stirring rod 5 pre-mixes the material in the bulk barrel 2, which helps to reduce the amount of large materials entering the mixing barrel 1 and improve the mixing quality. The bottom of the bulk barrel 2 is connected with a discharge pipe 3, and the discharge pipe 3 extends into the mixing barrel 1. The material in the bulk barrel 2 enters the mixing barrel 1 along the discharge pipe 3. The discharge pipe 3 and the discharge pipe 15 are both provided with a control valve 16. The control valve 16 allows precise control of the flow rate of the material and the discharge after mixing is completed.
[0025] Refer to the attached Figure 1-Figure 3, a frame 6 is fixedly installed on the top of the bulk barrel 2, and the No. 2 stirring rod 5 is rotatably connected to the frame 6 set on the same side. A pad 7 is fixedly installed between the bulk barrels 2 on both sides, and a top frame 8 is fixedly installed on the pad 7. A stepper motor 9 is fixedly installed on the top of the top frame 8. The output shaft of the stepper motor 9 is connected to the No. 1 stirring rod 4 through a coupling. When the stepper motor 9 is turned on during use, the rotation of the No. 1 stirring rod 4 can be realized. Vertical plates 10 are fixedly installed on both sides of the top frame 8, and a transmission rod 11 is rotatably installed on the vertical plate 10. By setting the vertical plate 10, the stability of the transmission rod 11 during use is guaranteed. The stirring rod 4 and the two transmission rods 11 are arranged vertically, and a No. 1 bevel gear set 12 is arranged between the No. 1 stirring rod 4 and the two transmission rods 11. The No. 2 stirring rod 5 and the transmission rod 11 arranged on the same side are arranged vertically, and a No. 2 bevel gear set 13 is arranged between the No. 2 stirring rod 5 and the transmission rod 11 arranged on the same side. Through the No. 1 bevel gear set 12, the synchronous rotation of the No. 1 stirring rod 4 and the transmission rods 11 on both sides is achieved, and through the No. 2 bevel gear set 13, the synchronous rotation of the transmission rod 11 and the No. 2 stirring rod 5 is achieved, thereby achieving the synchronous rotation of the No. 1 stirring rod 4 and the No. 2 stirring rod 5.
[0026] Refer to the attached Figure 1 A plurality of legs 14 are fixedly installed at the bottom of the mixing barrel 1. The legs 14 provide stable support for the entire device to ensure stability during operation. The top of the mixing barrel 1 and the top of the bulk barrel 2 are both removably installed with protective covers 17. The protective covers 17 are used to protect the stirring system to prevent external impurities from entering, while improving operational safety and avoiding splashing of materials during stirring.
[0027] The machine-made sand aggregate proportioning and feeding device drives the No. 1 stirring rod 4 to rotate through the stepping motor 9, and the No. 1 stirring rod 4 drives the transmission rods 11 on both sides to rotate synchronously through the No. 1 bevel gear set 12. The transmission rod 11 then drives the No. 2 stirring rods 5 in the two bulk barrels 2 to rotate respectively through the No. 2 bevel gear set 13. This linkage mechanism ensures that the materials in the mixing barrel 1 and the bulk barrel 2 can be stirred simultaneously and evenly to achieve efficient mixing. At the same time, by controlling the control valve 16 on the discharge pipe 3, the rate at which the material in the bulk barrel 2 enters the mixing barrel 1 can be adjusted to further control the proportion.
[0028] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
