Wherein, the feeding mechanism 2 is connected with stirring barrel 1, material enters stirring barrel 1 through the feeding mechanism 2;Stirring mechanism 3 is located in stirring barrel 1, for the material in stirring barrel 1 is stirred;Adjusting mechanism 4 is arranged on stirring barrel 1, the adjusting mechanism 4 can simultaneously adjust the stirring speed of stirring mechanism 3 and the discharge amount of feeding mechanism 2, so that the change of stirring speed and discharge amount can be synchronized, to ensure the uniformity of material stirring.

[0039] Specifically, as shown in Figure 1 , the stirring barrel 1 is provided with a plurality of feeding mechanisms 2, different materials enter the stirring barrel 1 through the respective feeding mechanisms 2, and the material used in the embodiment is industrial solid waste. The stirring barrel 1 is also connected with a discharge pipe 11 and a water spraying pipe 12, the discharge pipe 11 is arranged near the bottom of the stirring barrel 1, and a valve 13 is further arranged in the discharge pipe 11 to facilitate the control of the discharge operation. The water spraying pipe 12 is connected with an external water pump for water supply during the mixing process, and according to the actual demand, the water spraying pipe 12 can be provided with a plurality of pipes, which are evenly distributed along the circumference of the stirring barrel 1. In the embodiment, the water spraying pipe 12 is provided with two groups. In addition, the bottom of the stirring barrel 1 is also connected with a plurality of hydraulic cylinders 5, which can be used to lift the height of the entire stirring device, facilitating the transportation of the mixed material after stirring to the transport vehicle at different heights.

[0040] As shown in Figure 2 , Figure 3 , the feeding mechanism 2 includes an adjusting block 21, a feeding pipe 22 and a hopper 25, one end of the feeding pipe 22 is connected with the hopper 25, and the other end is connected with the stirring barrel 1. A sliding groove 23 is horizontally opened along the radial direction of the feeding pipe 22, one end of the adjusting block 21 is inserted into the sliding groove 23, and the adjusting block 21 can slide in and out to change the size of the feeding passage of the feeding pipe 22, thereby realizing the adjustment of the discharge amount.

[0041] The adjusting block 21 is also connected with a reset member 24, which is preferably a spring member, one end of the spring member is connected with the inner wall of the feeding pipe 22, and the other end is connected with the end of the adjusting block 21.

[0042] The feeding mechanism 2 can be provided with a plurality of types according to the types of materials, and is annularly distributed around the adjusting mechanism 4. In addition, when the adjusting block 21 slides to the innermost side of the sliding groove 23, the feeding passage should not be completely blocked to ensure that the feeding pipe 22 has a minimum feeding amount, which can be selected according to the actual working condition. In the embodiment, referring to Figure 6As shown, the feeding mechanism 2 is provided with two, and the adjusting block 21 and the suction accessory 42 of the adjusting mechanism 4 are displaced in the same horizontal plane. In addition, the minimum feeding amount of the feeding pipe 22 is half of the maximum feeding amount.

[0043] As shown, the adjusting mechanism 4 includes a first motor 41 and a suction accessory 42. Among them, the first motor 41 drives the stirring mechanism 3 and the suction accessory 42 at the same time, the suction accessory 42 dynamically adsorbs the adjusting block 21, changes the depth of the adjusting block 21 inserted into the feeding pipe 22 by changing the adsorption force between them, so as to adjust the amount of feeding. Because the size of the adsorption force of the suction accessory 42 to the adjusting block 21 changes synchronously with the speed of the first motor 41, and the stirring mechanism 3 is also driven by the first motor 41, so that the stirring speed of the stirring mechanism 3 and the feeding amount can be changed synchronously, thereby ensuring that the material can be better stirred under different feeding amounts.

Among them, the suction accessory 42 is located on the rotating disc 43, the output shaft of the first motor 41 penetrates the center of the rotating disc 43, and drives the rotating disc 43 to rotate synchronously.

In addition, the suction accessory 42 is preferably a magnetic ball, the elastic connecting piece 44 is a spring, and the adjusting block 21 is a metal block.

[0044] In order to ensure that the suction accessory 42 can smoothly move radially on the rotating disc 43, the rotating disc 43 is provided with a limiting groove for the movement of the suction accessory 42 along the radial direction thereof, and the bottom of the suction accessory 42 is provided with a protrusion which is clamped in the limiting groove.

[0045]

[0046] ​A stirring device for road base mixture in this embodiment, the dynamic adsorption process of the magnetic ball on the metal block is as follows: When the first motor 41 rotates at a constant speed, the centrifugal force on the magnetic ball is balanced with the centripetal force provided by the spring, and the magnetic ball is in a relatively stable state. The distance between the magnetic ball and the metal block is relatively constant, so that the adsorption force of the magnetic ball on the metal block is also relatively constant, thus making the size of the feeding channel relatively fixed. When the rotation speed of the first motor 41 changes, the stable state of the magnetic ball is broken, the adsorption force of the magnetic ball on the metal block also changes, and the depth of the metal block inserted into the feeding pipe 22 also changes, causing the feeding channel in the feeding pipe 22 to change correspondingly, so as to achieve the synchronous change between the rotation speed of the first motor 41 and the material feeding amount.

[0047] Specifically, when the rotation speed of the first motor 41 increases, the centrifugal force on the magnetic ball increases, and the magnetic ball slides outward along the limiting groove and approaches the metal block, so that the adsorption force on the metal block increases. When the adsorption force is greater than the pulling force of the resetting member 24, the metal block slides outward, increasing the feeding channel in the feeding pipe [i]22[ / i], and the feeding amount increases accordingly. At this time, due to the increase in the rotation speed of the first motor 41, the stirring speed of the stirring mechanism 3 increases synchronously. The principle when the rotation speed of the first motor 41 decreases is the same as above, but the result is opposite, which will not be elaborated here.

[0048] As Figure 4 shown, the stirring mechanism 3 includes a rotating shaft 31, and the end of the rotating shaft 31 is connected to the output shaft of the first motor 41. The rotating shaft 31 is provided with a first stirring component 32 and a second stirring component 33. Among them, the stirring radius of the first stirring component 32 is larger than that of the second stirring component 33, that is, the first stirring component 32 is used to stir the material near the inner wall of the stirring cylinder 1, and the second stirring component 33 is used to stir the material near the center in the stirring cylinder 1, so as to ensure the uniformity of material mixing.

[0049] Specifically in this embodiment, the first stirring component 32 includes a first cross beam 321, and both ends of the first cross beam 321 are provided with first stirring rods 322. The side wall of the first stirring rod 322 closely adheres to the inner wall of the stirring cylinder 1, and the bottom of the first stirring rod 322 contacts the bottom wall of the stirring cylinder 1.

[0050] The second stirring component 33 includes a second cross beam 331, and both ends of the second cross beam 331 are connected with second stirring rods 332. The second stirring rod 332 is in an overall "冂" shape to increase the stirring area. At the same time, second motors 34 are provided at both ends of the second cross beam 331, and the second stirring rods 332 are connected to the output shafts of the second motors 34. The second motors 34 can drive the second stirring rods 332 to rotate self - sufficiently, which can further improve the stirring efficiency. Preferably, a cavity is provided on the second cross beam 331, and the second motors 34 are located in the cavity.

[0051] The working process of the mixing device for road base mixture of the embodiment is as follows: first, different materials are respectively placed in the plurality of hoppers 25, the outflow amount of the materials in the hoppers 25 and the stirring speed of the stirring rods are controlled by controlling the rotating speed of the first motor 41. When it is needed to increase the input amount of the materials, the rotating speed of the first motor 41 is increased, the centrifugal force of the magnetic ball on the circular rotating disc is increased, the magnetic ball moves towards the direction close to the metal block, the metal block is attracted to move outwards from the sliding groove 23, the material passage in the feeding pipe 22 is enlarged, and thus the input amount of the materials is increased. At the same time, the stirring speeds of the first stirring rod 322 and the second stirring rod 332 are also increased synchronously. When it is needed to reduce the input amount of the materials, the rotating speed of the first motor 41 is reduced, the centrifugal force of the magnetic ball is reduced, the distance between the magnetic ball and the metal block is far, the attraction force of the magnetic ball on the metal block is small, when the attraction force of the magnetic ball on the metal block is smaller than the pulling force of the spring member on the feeding pipe 22, the metal block is pulled back to the original position by the spring member, and thus the input amount of the materials is reduced. Finally, when the mixing and stirring are completed, the height of the hydraulic cylinder 5 is adjusted to a suitable position, the valve 13 is opened, and the mixture is discharged.

[0052] The above description of the present application and its embodiments is illustrative and not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above description, without departing from the spirit of the present application, similar structural modes and embodiments can be designed without creativity, and all of them should belong to the protection scope of the present application.
