[0051] In yet another embodiment of the present invention:

[0052] Please refer to Figure 1-3 A mixing motor 104 is provided on the upper part of the double-layer stirring control box 103, and a stirring rod 105 is provided at the output end of the mixing motor 104;

[0053] The double-layer stirring control box 103 includes an upper mixing layer and a lower polymerization bucket 113;

[0054] The bottom of the upper mixing layer is provided with a discharge port which is connected to the upper part of the discharge barrel pipe 111, and the top of the lower polymerization hopper 113 is connected to the bottom of the discharge barrel pipe 111;

[0055] The stirring rod 105 is sleeved with a sleeve stirring seat 106, and the sleeve stirring seat 106 includes an upper mixing and stirring group 2 located in the upper mixing layer and a lower discharge control group located on the upper part of the lower polymerization bucket 113;

[0056] The upper rotation stroke of the lower discharge control group covers the lower outlet of the discharge barrel pipe 111.

[0057] Please pay attention to Figure 2 , Figure 3 The upper mixing layer includes a stirring filter cabin plate 109, the sleeve rod stirring seat 106 is arranged inside the stirring filter cabin plate 109, and a plurality of stirring rollers 108 are arranged on the surrounding side of the sleeve rod stirring seat 106.

[0058] Please pay attention to Figure 2The lower discharge control group includes a bottom center sleeve 114 sleeved on the side of the stirring rod 105, a sealing disk is provided on the top of the bottom center sleeve 114, a discharge trough 116 is provided on the sealing disk, a shielding plate 117 is provided inside the discharge trough 116, and the shielding plate 117 is distributed in multiple sections and is evenly distributed inside the discharge trough 116 at intervals. The rotation stroke of the shielding plate 117 and the discharge trough 116 includes the lower discharge port of the discharge barrel tube 111;

[0059] The bottom of the lower polymerization bucket 113 is connected to the top of the pumping pipe 401 , and a plurality of inclined stirring plates 115 are provided around the bottom center sleeve 114 . The inclination angle of the inclined stirring plates 115 is parallel to the inclination angle of the surface of the lower polymerization bucket 113 .

[0060] For reference Figure 1 The two filling powder tanks 101 are used to fill two different materials of the same group, and the two double-layer mixing control boxes 103 can be used to mix different mixed material groups. For the internal mixing method, refer to Figure 2 Figure 3 There is a driving relationship between the sleeve stirring seat 106 and the stirring rod 105. The stirring rod 105 drives the stirring roller 108 guide plate to fill the mixture into the discharge barrel pipe 111. The bottom of the discharge barrel pipe 111 is opened and closed by the rotation of the motor. After the sleeve stirring seat 106 rotates, the bottom center sleeve 114 and the baffle 117 rotate, and the rotation of the stirring motor 201 is an angle rotation. In the initial position, the baffle 117 forms a shield on the bottom of the discharge barrel pipe 111. When rotating, the discharge chute 116 is opened, and the channel of the discharge barrel pipe 111 is opened to throw the material into the lower polymerization bucket 113, so that it is stirred and aggregated into the pumping pipe 401. The inside of the pumping pipe 401 can be transported at a fixed time or after it is full. In this way, the discharge amount inside a single double-layer stirring control box 103 can be controlled only by the rotation of the motor. With the cooperation of multiple double-layer stirring control boxes 103, the asphalt mixture can be measured and finally transported to the driving pump 4 for stirring.

[0061] In another embodiment of the present invention:

[0062] Please pay attention to Figure 1, a filter cabin height isolation disk 112 is provided inside the upper mixing layer, and the filter cabin height isolation disk 112 is sleeved on the outside of the upper mixing and stirring group 2, and a spatial fluid mixing zone 110 is formed outside the filter cabin height isolation disk 112, and external limit switches 122 are provided on both sides of the filter cabin height isolation disk 112 to adjust the upper and lower heights, and the filter cabin height isolation disk 112 and the upper mixing and stirring group 2 are connected and disconnected by changing the height of the filter cabin height isolation disk 112; a guide groove 121 is provided on the outside of the stirring filter cabin disk 109, and a guide block 120 is provided on the inner wall of the filter cabin height isolation disk 112, and the guide block 120 is located in the guide groove 121 and is slidably connected, and the external limit switch 122 is fixed to the outside of the double-layer stirring control box 103 to change the height through mechanical adjustment;

[0063] When there is a fluid in the mixture, following the rotation of the stirring rod 105, the flow state inside the fluid mixing area 110 will be better than the flow state of the mixture inside the stirring filter tank disc 109. By adjusting the height of the external limit switch 122, the guide block 120 slides in the guide groove 121, thereby filling the fluid mixing area 110 area, which can balance the density state of the mixture inside the stirring filter tank disc 109 and improve the mixing effect. That is, the excess fluid material will be automatically guided to the fluid mixing area 110 area. When the fluid mixing area 110 is full, there is always a maximum limit of fluid carrying capacity inside 109, and the fluid in the fluid mixing area 110 will automatically form a reflux effect to supplement the internal mixing state at the limit value.

[0064] Please pay attention to Figure 2 , Figure 3 The stirring group 2 includes a stirring motor 201, a primary stirring tank 202, and a secondary stirring tank 203. The stirring end of the stirring motor 201 extends into the primary stirring tank 202 and the secondary stirring tank 203. The primary stirring tank 202 and the secondary stirring tank 203 are arranged in an upper and lower arrangement. A connecting valve is provided between the secondary stirring tank 203 and the primary stirring tank 202.

[0065] A material guide inclined plate 301 is provided on the internal floor of the material storage box 3, and the secondary stirring tank 203 is located inside the material storage box 3 on the lower side close to the material guide inclined plate 301, and the side of the secondary stirring tank 203 close to the material guide inclined plate 301 is in an open state, and the discharge port of the material storage box 3 is located at the bottom of the stirring stroke range of the stirring group 2.

[0066] The stirring method of the stirring group 2 is roughly a two-level stirring method. The upper first-level stirring tank 202 stirs the material, and the lower stirring roller 108 extends into the storage box 3 to stir the existing mixed material, thereby implementing all-round stirring of the temporary storage material through a motor. In addition, the specific structure inside the storage box 3 is not shown in the figure. The structural state can be known through the text description. The guide plate is a guide surface used to guide the mixed material on one side for repeated stirring and mixing, and the fluidity during temporary storage is extremely high. The connection method between the storage box 3 and the first-level stirring tank 202 is not described accordingly and is regarded as a normal stirring and temporary storage structure effect.

[0067] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components.
