[0023] As follows, embodiments are further described with reference to the accompanying drawings.

[0024] like Figures 1 to 3 As shown in FIG. 1 , as a preferred embodiment 1, a shaft rotationally symmetrical material distribution device comprises a rotary center column 5 vertically arranged in the middle of a sliding form platform 11, wherein the top of the rotary center column 5 is fixedly matched with the middle of the bottom of the rotary bracket 4, and the rotary bracket 4 is rotationally matched with the sliding form platform 11 through the rotary center column 5, thereby ensuring that the device as a whole rotates around the axis;

[0025] Both ends of the slewing bracket 4 are provided with a walking mechanism 6, and a circular track 7 is coaxially provided on the sliding platform 11 near the outer side. The slewing bracket 4 moves along the circular track 7 through the walking mechanism 6, providing driving force for rotation around the axis, without manual rotation;

[0026] Feeding belts 1 are provided on both sides of the top of the rotating bracket 4, and the feeding belts 1 are symmetrical about the middle position of the rotating bracket 4, which is convenient for horizontal distribution and feeding from the middle to both sides, thereby improving feeding efficiency and realizing symmetrical unloading. A flexible scraping mechanism 9 is provided at the bottom of the discharge end of each feeding belt 1, and a distribution hopper 3 is provided at the top of the middle position of the rotating bracket 4. The distribution hopper 3 is provided with two discharge ports, and a receiving hopper 2 is provided at the bottom of the two discharge ports of the distribution hopper 3. The receiving hopper 2 corresponds to the feeding belt 1 one by one, and the discharge port of the receiving hopper 2 is located above the feed end of the corresponding feeding belt 1, which is convenient for separating the feeding.

[0027] The conveying directions of the feeding belt conveyors 1 on both sides are along the rotating bracket 4 away from the middle position of the rotating bracket 4, with material unloading in the middle and material discharging on both sides to achieve symmetrical unloading.

[0028] The feeding belt conveyor 1 is supported and fixedly matched with the rotary bracket 4 through the I-beam crossbeam 10 to ensure the stability of the installation and leave space for installing the flexible scraping mechanism 9.

[0029] The discharge end of the feeding belt conveyor 1 is provided with a string tube 8, which extends vertically downward, and the discharge end of the string tube 8 is located between the lining edge line and the shaft wall line. The discharge end of the feeding belt conveyor 1 and the flexible scraping mechanism 9 are both located within the feed end range of the string tube 8 on the corresponding side, ensuring that both the unloading and scraping materials directly enter the string tube 8 to complete directional unloading, which is used for vertical shaft construction to prevent dripping.

[0030] The flexible scraping mechanism 9 includes a scraping plate 91, one end of which is hingedly fitted with the lower end of the base of the feeding belt conveyor 1 through a shaft 93, and a portion of the scraping plate 91 away from the shaft 93 is stretched and fitted with the upper end of the base of the feeding belt conveyor 1 through a tension spring 92. The scraping end of the scraping plate 91 is pressed and fitted with the lower belt of the feeding belt conveyor 1 through the tension spring 92. The tension spring 92 makes the scraping plate and the lower belt tightly attached to scrape the concrete remaining on the belt that has been unloaded, thereby satisfying the scraping requirements while reducing the wear on the belt.

[0031] One end of the tension spring 92 is rotatably connected to the upper end of the base of the feeding belt conveyor 1, and the other end of the tension spring 92 is rotatably connected to a part of the scraper plate 91 away from the shaft 93, and tension springs 92 are provided on both sides of the scraper plate 91 to ensure the effectiveness and stability of the scraping.

[0032] The rotating center column 5 includes a rotating outer column and a rotating inner column that are sleeved together, and the rotating outer column and the rotating inner column form a rotational fit through bearings. The end of the rotating outer column away from the rotating inner column forms a fixed fit with the middle position of the sliding platform 11, and the end of the rotating inner column away from the rotating outer column forms a fixed fit with the middle position of the rotating bracket 4, ensuring smooth rotation around the axis.

[0033] The walking mechanism 6 includes a column arranged at the bottom end of the slewing bracket 4, and a universal walking wheel and a driving motor are provided at the bottom of the column. The column forms a limited sliding fit with the annular track 7 through the walking wheel, and the walking wheel forms a transmission fit with the output shaft of the driving motor. By driving the motor forward and reverse, the slewing bracket 4 can rotate forward and reverse around the slewing center column 5, thereby realizing rotationally symmetrical continuous feeding, and better ensuring the quality of concrete pouring and construction safety.

[0034] As a preferred embodiment 2, a partition baffle is vertically provided in the middle of the distribution hopper 3, and the discharge port of the distribution hopper 3 is symmetrical about the partition baffle, dividing the delivered concrete into two parts, thereby realizing simultaneous feeding of the receiving hoppers 2 of the two feeding belt machines 1.

[0035] The working principle of this utility model:

[0036] The utility model provides driving force through the walking mechanism 6, which makes the slewing bracket 4 rotate around the slewing center column 5. At this time, the material is distributed to the receiving hopper 2 on both sides through the distribution hopper 3. After the material is discharged from the receiving hopper 2, it is fed to the corresponding feeding belt conveyor 1, and the material is discharged to both sides at the same time, and discharged through the string drum 8, realizing symmetrical material discharge while rotating, thereby improving the material discharge efficiency;

[0037] The flexible scraping mechanism 9 is used to flexibly scrape the belt after unloading, which does not damage the belt while ensuring the integrity and stability of the unloading, thereby improving the unloading efficiency and quality.
