For some known technologies, those skilled in the art may also adopt other alternative methods to implement; and the drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides an asphalt production feeding equipment capable of automatically adjusting the ratio, comprising: a material box 1 for storing auxiliary materials for asphalt mixing, a raised seat 2 is provided at the bottom of the material box 1, a metering component 10 is provided at the bottom of the raised seat 2, the metering component 10 adopts accessories such as an electronic scale or a pressure sensor, the purpose of which is to weigh the material box 1 as a whole in real time; a feeding pipe 4, which passes through the interior of the material box 1 in an inclined shape, and a conveying auger 11 for conveying materials is rotatably connected inside the feeding pipe 4, and the conveying auger 11 can cooperate with The wall of the feed pipe 4 transports the material inside the feed pipe 4 to one end, a feed port 12 is provided on the wall of the feed pipe 4 located inside the material box 1, a discharge port 13 is provided on the wall of the feed pipe 4 located outside the material box 1, and a drop pipe 5 is provided below the discharge port 13; a feeding pipe 7 is provided with a sleeve 8 on the top, and the top of the sleeve 8 is ring-covered on the outside of the bottom end of the drop pipe 5, and the two do not contact each other, ensuring that there is no contact between the drop pipe 5 and the sleeve 8, thereby avoiding the influence of contact force on the accurate measurement of the overall weight of the material box 1 by the metering component 10.

[0024] By arranging an inclined feeding pipe 4 inside the material box 1 and equipping it with an internal conveying auger 11, stable transportation of materials from the inside to the outside of the material box 1 is achieved. At the same time, the overall weight of the material box 1 is measured in real time by the metering component 10, and the output material weight is controlled according to the weight change, thereby realizing automatic proportioning of auxiliary materials and improving work efficiency.

[0025] like Figure 1 As shown, a hopper 3 connected to the outside is provided on the top of the material box 1 for replenishing materials. The hopper 3 is in an upward open structure for easy addition of materials.

[0026] like Figure 2As shown, the upper end of the feed pipe 4 is fixedly connected to a rotating seat 6 for rotationally connecting to a conveying auger 11; the end of the feed pipe 4 away from the rotating seat 6 is externally fixedly connected to a motor 9; the output end of the motor 9 is fixedly connected to the end of the conveying auger 11.

[0027] The conveying auger 11 is driven by the motor 9 to rotate inside the feeding pipe 4 , and the rotating seat 6 is provided to support the end of the conveying auger 11 away from the motor 9 , thereby ensuring the stability of the rotating structure of the conveying auger 11 .

[0028] like Figure 2 As shown, a groove 14 is formed on the height-enhancing seat 2 . The groove 14 is an oblique through-slot structure, and the motor 9 is accommodated in the groove 14 .

[0029] Among them, the motor 9 and the metering component 10 are electrically connected through the control module. When working, the auxiliary material ratio is calculated according to the asphalt weight, and the rated weight of the auxiliary material ratio is manually input into the control module. The metering component 10 records the initial weight of the material box 1, and records the weight change in real time as the material is transported, and sends it to the control module. When the change reaches the rated weight, the control module sends an electrical signal to control the motor 9 to stop and the material stops being transported. At this time, the material put in reaches the rated weight.

[0030] like Figure 2 As shown, it also includes a guide platform 15, which is a wedge-shaped block structure, and the top is an inclined plane with the same inclination angle as the feeding pipe 4, and the feeding pipe 4 is embedded above the guide platform 15; the feed port 12 is located above the tube body of the feeding pipe 4 near the bottom end, and the discharge port 13 is located below the tube body of the feeding pipe 4 near the top end.

[0033] Through this arrangement, the materials falling through the drop tube 5 are all received by the sleeve 8, which prevents the materials from scattering, resulting in the weight of the materials actually added being less than the weight of the configured materials, thereby further ensuring the proportioning accuracy.

[0034] The technical solution provided by the utility model, in actual use, supplements auxiliary materials to the inside of the material box 1 through the hopper 3, wherein a single asphalt mixing device is equipped with multiple devices of the present invention, which are respectively used to add auxiliary materials such as mineral powder, cellulose, plastic, etc., and the weight of the metering component 10 is reset before the motor 9 is started, and the motor 9 is started to drive the conveying auger 11 to rotate, and the material collapses into the inside of the feeding pipe 4 through the feed port 12, and the conveying auger 11 cooperates with the inner wall of the feeding pipe 4 to convey the material to one end of the upper discharge port 13, when the material is conveyed to the discharge port 13, under the action of gravity, it falls under the guidance of the drop pipe 5, and is then received by the sleeve 8 into the inside of the feeding pipe 7, wherein a feeding component for conveying materials is provided inside the feeding pipe 7, including but not limited to a feeding push plate or a conveying screw, etc., the purpose is to convey the materials accumulated in the feeding pipe 7 to the asphalt mixing device, on the other hand, the real-time weight change of the material box 1 is detected by the metering component 10, and when the change reaches the rated weight, the motor 9 stops to complete the automatic proportioning and feeding.

[0035] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.
