[0040] Specifically, when the concrete filling operation is needed, the winding machine 7 installed on the top of the mounting plate 6 is started, and the winding machine 7 starts to work, and the two steel wires 8 outside the winding machine 7 are reeled in and out. Since the ends of the steel wires 8 are fixedly connected with the T-shaped sliding blocks 9, and the plurality of T-shaped sliding blocks 9 are respectively slidably connected in the T-shaped grooves 5 opened on the adjacent side of the two guide plates 4, when the steel wires 8 are reeled in and out, the T-shaped sliding blocks 9 will stably slide up and down in the T-shaped grooves 5, thereby driving the rotating connection of the rotating rod 10 to move. The middle part of the rotating rod 10 is rotatably connected with the landing gear 11. In the movement process of the rotating rod 10, the landing gear 11 will be lifted up and down, and at this time, the tipping cart 12 placed on the top of the landing gear 11 will also be driven to rise or fall. After the tipping cart 12 is lifted to the appropriate position, the locking assembly arranged on the front and rear sides of the top end of the landing gear 11 starts to play a role.

Since the plurality of gears 201 are respectively rotatably connected to the front and rear sides of the middle lower part of the mixing box 3, and the front two gears 201 and the rear two gears 201 are respectively engaged with each other, when the abutting frame 202 moves, the closing plate 205 fixedly connected to the bottom of the abutting frame 202 will also move. The top walls of the two closing plates 205 and the bottom of the mixing box 3 are designed with the same radian arc shape, so that the closing plate 205 can be tightly abutted with the bottom of the mixing box 3 during movement, thereby realizing the opening and closing control of the discharge port. During the opening of the discharge port by the closing plate 205, the gears 201 will rotate on the mixing box 3 correspondingly to cooperate with the movement track of the closing plate 205, so as to ensure the smooth discharge process. The protective cover 206 arranged outside the plurality of gears 201 plays a role of protecting the gears 201, preventing sundries from entering the meshing part of the gears 201 to affect the normal rotation of the gears 201, and avoiding the accidental contact of the gears 201 by the operator to cause safety accidents. When the discharging is completed, the hydraulic rod 204 works reversely to drive the closing plate 205 to return to the initial position to close the discharge port, so as to prepare for the next concrete production operation, so that the discharging process of the concrete can be accurately and efficiently controlled, and the stable operation and production efficiency of the entire automatic filling device for concrete production are ensured.

The bottom left and right ends of the steel structure outer frame 1 are fixedly connected with horizontal bottom plates 17, and the two horizontal bottom plates 17 are vertically installed on the bottom of the steel structure outer frame 1, and the interiors of the two horizontal bottom plates 17 are designed as hollow. A plurality of reinforcing ribs 18 are fixedly installed outside the steel structure outer frame 1, and the plurality of reinforcing ribs 18 are designed as hollow. The right end of the hopper cart 12 is fixedly installed with two rubber handles 19, and the outer walls of the two rubber handles 19 are designed as anti-skid. The top front and rear sides of the mounting plate 6 are fixedly installed with guide wheels one 20, and the top of the two T-shaped grooves 5 is fixedly installed with guide wheels two 21. The outer walls of the two guide wheels one 20 and the guide wheels two 21 are respectively abutted with the two steel ropes 8;

[0044] Specifically, the maintenance escalator 16 facilitates the maintenance of the mixing box 3 and related components by the operator; the transverse bottom plate 17 provides stable bottom support for the entire device, and the hollow design not only ensures the strength but also reduces the weight of the device; the reinforcing rib 18 adopts a hollow design to enhance the overall strength and stability of the steel structure outer frame 1; the rubber handle 19 facilitates the operator to push or control the tipping cart 12, and the anti-skid outer wall can prevent hand slipping; the guide wheel one 20 and the guide wheel two 21 are respectively attached to the steel ropes 8 to guide the winding and unwinding of the steel ropes 8, ensuring their stable operation in the T-shaped grooves 5, thereby ensuring the smooth lifting action of the landing gear 11 and making the collaborative work of each component of the automatic filling device for concrete production more reliable and efficient.

The middle part of the rotating rod 10 is rotatably connected to the landing gear 11, and in the movement process of the rotating rod 10, the landing gear 11 will perform a lifting action, and at this time, the tipping cart 12 placed on the top of the landing gear 11 will also be driven to rise or fall. After the tipping cart 12 is raised to the appropriate position, the locking assembly provided on the front and rear sides of the top end of the landing gear 11 starts to work. The two L-shaped clamping blocks 13 in the locking assembly are fixedly connected to the right side of the top of the landing gear 11, and their interiors are mutually clamped with the left side of the top of the tipping cart 12. In this way, the position of the tipping cart 12 on the landing gear 11 can be stabilized to prevent displacement during subsequent operation. At the same time, the press-type trigger 14 fixedly installed on the right side of the middle part of the landing gear 11 and the electric telescopic limiting column 15 fixedly installed on the right side of the top of the landing gear 11 also play the role of auxiliary fixation and safety protection. When the tipping cart 12 reaches the designated position and is locked by the L-shaped clamping blocks 13, the left side of the electric telescopic limiting column 15 is attached to the right side of the bottom of the tipping cart 12, further enhancing the stability of the tipping cart 12. When the filling operation is completed, the winding machine 7 works in reverse to loosen the steel ropes 8, so that the landing gear 11 is lowered, thereby lowering the tipping cart 12 filled with concrete to the ground for subsequent transportation work.

[0046] And, when the discharge operation is needed, the two hydraulic rods 204 are started to work synchronously, through the extension and retraction of the hydraulic rods 204, the movement of the attached frame 202 is driven, since the plurality of gears 201 are respectively rotatably connected to the front and rear sides of the middle lower part of the stirring box 3, and the front two gears 201 and the rear two gears 201 are respectively engaged with each other, when the attached frame 202 moves, the closing plate 205 fixedly connected to the bottom thereof will also move, the top wall of the two closing plates 205 and the bottom of the stirring box 3 are designed with the same radian arc, so that the closing plate 205 can be tightly attached to the bottom of the stirring box 3 during the movement, so as to realize the opening and closing control of the discharge port, during the opening of the discharge port by the closing plate 205, the gears 201 will rotate on the stirring box 3 correspondingly to cooperate with the movement track of the closing plate 205, to ensure the smooth discharge process, and the protective cover 206 arranged outside the plurality of gears 201 plays a role in protecting the gears 201, preventing sundries from entering the meshing part of the gears 201, affecting the normal rotation, and also avoiding the accidental contact of the gears 201 by the operator to cause safety accidents, when the discharge is completed, the hydraulic rod 204 works reversely to drive the closing plate 205 to return to the initial position, and the discharge port is closed, ready for the next concrete production operation.
