A fixed rod 14 is fixedly connected to the left side of the connecting rod 13, and a collar 15 is fixedly connected to the left side of the fixed rod 14. The inner side of the collar 15 is rotatably connected to the outside of the vertical sleeve rod 6, and an auxiliary blanking assembly is provided on the top of the tank body 1. The purpose of this arrangement is that when in use, the raw materials are poured into the interior of the tank body 1 from the feed port, and the rotating shaft 4 and the vertical sleeve column are driven to rotate by starting the motor 3, and the active bevel gear 5 is driven to rotate, and further the driven bevel gear 9 meshing with it is driven to rotate, and then the turntable 10 and the eccentric shaft 11 are driven to rotate by the rotating rod 8. Under the action of the hollow frame 12, the circumferential operation of the eccentric shaft 11 is converted into the linear motion of the hollow frame 12, and the connecting rod 13 is driven to reciprocate up and down, and then the vertical sleeve rod 6 is driven to perform reciprocating lifting and lowering motion on the outside of the rotating shaft 4 under the action of the fixed rod 14 and the collar 15, so that the vertical sleeve rod 6 can perform reciprocating lifting and lowering motion while rotating, thereby promoting the mixing of the raw materials.

[0030] Embodiment 2
[0031] As shown in Figure 2 and Figure 3 Based on the same concept as in Embodiment 1, this embodiment also proposes an auxiliary discharging assembly including a supporting frame 16 and a fixed seat 19. The supporting frame 16 is fixedly connected to the front side of the tank body 1, and the fixed seat 19 is fixedly connected to the bottom of the tank body 1. The bottom of the supporting frame 16 is fixedly connected to a motor 2, and the output end of the motor 2 is fixedly connected to a cam 18. The inside of the fixed seat 19 is rotatably connected to a lever 20, the right side of the lever 20 is fixedly connected to a knocking hammer 21, and a spring 22 is arranged between the lever 20 and the tank body 1. This arrangement can start the motor 2 while the concrete is being mixed. With the continuous driving of the motor 2, the cam 18 rotates at a predetermined intermittent rhythm. In this process, the cam 18 will intermittently collide and abut against the lever 20. When the cam 18 rotates to the position where it contacts the lever 20, the resulting force between the two causes the lever 20 to be strongly pushed. At the moment when the cam 18 abuts against the lever 20, the lever 20 is pushed by the cam 18 and exerts a pulling force on the spring 22. Due to the elastic properties of the spring 22, it starts to deform and is gradually stretched under the action of the pulling force. Since the lever 20 is rotatably connected to the fixed seat 19, under the combined action of the pushing force from the cam 18 and the pulling force from the spring 22, the lever 20 starts to rotate around the shaft of the fixed seat 19 and is lifted up. The lifting action of the lever 20 drives the knocking hammer 21 connected thereto to move. Under the driving of the lever 20, the knocking hammer 21 starts to make back-and-forth knocking actions within a certain range to knock the tank body 1. The discharge port 24 valve can be opened for discharging. The auxiliary discharging assembly not only ensures that the raw materials can be fully mixed in the tank body 1 and improves the uniformity of the mixing, but also has the dual functions of auxiliary discharging and preventing the discharge port 24 from being blocked, which makes the discharge of the concrete from the discharge port 24 more smooth and reduces the problem of reduced discharging rate caused by blockage, ensuring the smooth progress of the production process.
[0032] Preferably, one end of the spring 22 is fixedly connected to the bottom of the tank body 1, and the other end of the spring 22 is fixedly connected to the top of the lever 20, and the purpose of such arrangement is to drive the lever 20 to reset when the cam 18 and the lever 20 are not in abutment.
[0033] Preferably, the cam 18 and the lever 20 are in abutment, and the knocking hammer 21 and the tank body 1 are in abutment, and the purpose of such arrangement is that the abutment of the cam 18 and the lever 20 can convert the rotating motion of the cam 18 into the pushing action on the lever 20, and the abutment of the knocking hammer 21 and the tank body 1 can effectively transmit the vibration generated by the knocking to the inside of the tank body 1.
[0034] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
