[0020] See also Figure 1 - Figure 4The utility model provides a technical solution: a high-efficiency discharging device for a concrete mixer, comprising a discharging trough 1, a No. 1 discharging port 2 and a partition 4. A No. 1 discharging port 2 is arranged on one side of the discharging end of the discharging trough 1. The discharging trough 1 can conduct and discharge the concrete mixed by the concrete mixer into the collecting hopper. A No. 2 discharging port 3 is arranged on one side of the No. 1 discharging port 2. The No. 1 discharging port 2 and the No. 2 discharging port 3 are both connected to the discharging trough 1. The No. 1 discharging port 2 and the No. 2 discharging port 3 are in a "human" shape with the discharging trough 1. The partition 4 is connected to the middle of the No. 1 discharging port 2 and the No. 2 discharging port 3 through a rotating shaft. The No. 1 discharging port 2 can be rotated to the No. 2 discharging port 3. 2 and one of the two discharge ports 3 is blocked so that concrete can be discharged from the other side. In this way, after one hopper is full and ready for lifting, the partition 4 at the upper end of the trough is changed to another direction, and the hopper on the other side can continue to be loaded with concrete, saving the time for the hopper to wait for being filled with concrete and improving the concrete transportation efficiency. Limiting grooves 5 are provided on the inner walls of both sides of the discharge trough 1. The limiting grooves 5 can make the partition 4 limit after blocking. The inner walls of the two groups of limiting grooves 5 are provided with magnetic strips 6. Magnetic blocks 7 are arranged and connected on both sides of the end of the partition 4. The magnetic blocks 7 and the magnetic strips 6 attract each other, so that the blocked partition 4 is not easy to be loosened.

[0021] The outer walls of the No. 1 discharge port 2 and the No. 2 discharge port 3 are both provided with extended slots 8, which serve to extend the discharge port, so that the discharge port can be extended through the extended slots 8 when facing different situations, so as to facilitate better discharge. The middle part of the outer wall of the No. 1 discharge port 2 and the No. 2 discharge port 3 is provided with a limiting slide groove 9, and the inner walls on both sides of the extended slot 8 are provided with sliders 10, which are embedded in the limiting slide grooves 9. The sliders 10 can slide in the limiting slide grooves 9 to assist the extended slots 8 to slide on the outer walls of the No. 1 discharge port 2 and the No. 2 discharge port 3 to play a limiting role.

[0022] A card slot 11 is arranged on the top of the limiting slide groove 9, and an active cavity 12 is arranged above the inner walls on both sides of the extended slot 8. A card block 13 is embedded in the active cavity 12, and one end of the card block 13 is embedded in the card slot 11. The card block 13 is embedded in the card slot 11 to achieve a fixed limiting effect on the extended slot 8.

[0023] The end of the block 13 away from the slot 11 is connected to a connecting rod 14, and a spring 15 is provided on the outer wall of the connecting rod 14. The end of the connecting rod 14 away from the block 13 passes through the extended slot 8 and is connected to a pulling block 16. Pulling the pulling block 16 can drive the connecting rod 14 to move outward, thereby driving the block 13 to move out of the slot 11, so as to facilitate the adjustment of the extension degree of the extended slot 11. After adjusting to the corresponding position, the pulling block 16 is released, and the block 13 is embedded in the slot 11 at the corresponding position through the rebound force of the spring 15, completing the fixation of the extended slot 8, thereby realizing the extension of the No. 1 discharge port 2 and the No. 2 discharge port 3 to facilitate discharge under different circumstances.

[0024] A support column 17 is connected to one side of the bottom end of the discharge chute 1 through a rotating shaft. The support column 17 starts the supporting function. A drive box 18 is arranged on one side of the support column 17. The drive box 18 plays a connecting driving role. The inner walls of the bottom of both sides of the drive box 18 are connected to threaded barrels 19 through bearings. The threaded barrel 19 can rotate in the drive box 18. The top of the threaded barrel 19 passes through the drive box 18 and is threadedly connected with a screw 20. The end of the screw 20 away from the threaded barrel 19 is connected to the discharge chute 1 through a rotating shaft.

[0025] The bottom outer wall key of the threaded barrel 19 is connected to a worm wheel 21, and the inner wall of one side of the drive box 18 is connected to a worm 22 through a bearing. The worm 22 is meshed with the worm wheel 21. The outer wall of one side of the drive box 18 is connected to a servo motor 23, and the output end of the servo motor 23 is connected to the worm 22. The servo motor 23 can drive the worm 22 to rotate, and the rotation of the worm 22 drives the worm wheel 21 to rotate. The rotation of the worm wheel 21 drives the threaded barrel 19 to rotate, thereby driving the screw 18 to move up and down. The lifting of the screw 18 can drive one side of the discharge trough 1 to move up and down, thereby realizing the adjustment of the discharge angle inclination of the discharge trough 1, which is convenient for efficient discharge.

[0026] Working principle: When using a high-efficiency discharging device for a concrete mixer, the discharging trough 1 is fixed at the discharging port of the concrete mixer. The concrete mixed by the concrete mixer can be conducted and discharged into the aggregate hopper through the discharging trough 1. The No. 1 discharging port 2 and the No. 2 discharging port 3 are in a "human" shape with the discharging trough 1. The partition 4 is connected to the middle of the No. 1 discharging port 2 and the No. 2 discharging port 3 through a rotating shaft. By rotating the partition 4, one side of the No. 1 discharging port 2 and the No. 2 discharging port 3 can be blocked so that the concrete can be discharged from the other side. In this way, after one aggregate hopper is full and ready for lifting, the partition 4 at the upper end of the trough is changed in direction, and the aggregate hopper on the other side can continue to be loaded with concrete, saving the time for the aggregate hopper to wait for being filled with concrete and improving concrete transportation efficiency. The limit groove 5 allows the partition 4 to limit after blocking, and the magnetic block 7 and the magnetic strip 6 attract each other. The blocked partition 4 is not easy to be loosened easily. Pulling the pull block 16 can drive the connecting rod 14 to move outward, thereby driving the card block 13 to move out of the card slot 11, so as to facilitate the adjustment of the extension degree of the extended slot 11. After adjusting to the corresponding position, the pull block 16 is released, and the card block 13 is embedded in the card slot 11 at the corresponding position through the rebound force of the spring 15, completing the fixation of the extended slot 8, thereby realizing the extension of the No. 1 discharge port 2 and the No. 2 discharge port 3, which is convenient for discharging in different situations. The servo motor 23 can drive the worm 22 to rotate, and the rotation of the worm 22 drives the worm wheel 21 to rotate, and the rotation of the worm wheel 21 drives the threaded barrel 19 to rotate, thereby driving the screw 18 to perform a lifting movement. The lifting of the screw 18 can drive one side of the discharge trough 1 to perform lifting and adjustment, thereby realizing the adjustment of the discharge angle inclination of the discharge trough 1, which is convenient for efficient discharge.
