As shown in fig. 5 and 6, six left mounting blocks 11 are distributed on the right side of the left circular ring 101, and symmetrically, six right mounting blocks 12 are distributed on the left side of the right circular ring 102, and the six left mounting blocks 11 are respectively connected with the six right mounting blocks 12 through six connecting rods 10. Taking one of the left mounting blocks 11, the right mounting block 12 and the connecting rod 10 corresponding thereto as an example, the left mounting block 11 is rotatably mounted on the left circular ring 101 through a left main rotating shaft 241, the right mounting block 12 is rotatably mounted on the right circular ring 102 through a right main rotating shaft 242, the left and right main

rotating shafts

241 and 242 are located on the same straight line, and both are used as a main rotating shaft 24, and the main rotating shaft 24 is parallel to the horizontal main axis 2. Since the left mounting block 11 is connected to the right mounting block 12 by the connecting rod 10, the left and

right mounting blocks

11, 12 can rotate simultaneously about the left and right main

rotating shafts

241, 242, respectively. The left and

right mounting blocks

11, 12 are symmetrical in structure, taking the left mounting block 11 as an example, as shown in fig. 7, the left mounting block 11 is circular, and a mounting hole 8 for mounting the left main rotating shaft 241 is formed at the center of the circle. The middle part of the left mounting block 11 is provided with a horizontal mounting groove 15, and the lower part of the left mounting block 11 is provided with a groove 14 for mounting the connecting rod 10. The left and right sides of the storage box 13 for accommodating articles are respectively inserted into the horizontal mounting grooves 15 of the left and

right mounting blocks

right mounting blocks

11 and 12 and the main rotating shaft 24, and the storage box 13 can rotate around the main rotating shaft 24. The motor 4 drives the rotation wheel 1 to rotate, and accordingly, the storage box 13 mounted on the rotation wheel 1 makes a circular motion.

As shown in fig. 9, an eccentric shaft 9 is fixed to the left side of the left circular ring 101, the eccentric shaft 9 is horizontally arranged, the starting end of the eccentric shaft 9 is located at the horizontal main axis 2 and is connected with the horizontal main axis 25 (in fig. 9, the horizontal main axis 25 is shielded by the eccentric shaft 9), and the tail end of the eccentric shaft 9 is located at the horizontal secondary axis 23 which is parallel to the horizontal main axis 2 and the horizontal main axis 2 is in the same horizontal plane. As shown in fig. 8, a circular auxiliary rotating body 5 is disposed on the left side of the left circular ring 101, the auxiliary rotating body 5 is connected to the end of the eccentric shaft 9 at the center of the circle (in fig. 8, the eccentric shaft 9 is blocked by the auxiliary rotating body 5), the center of the auxiliary rotating body 5 is located on the horizontal minor axis 23, and the auxiliary rotating body 5 can rotate around the horizontal minor axis 23. As shown in fig. 8 and 9, six circular weights 6 are circumferentially arranged between the auxiliary rotating body 5 and the left circular ring 101, and one of the weights 6 will be described as an example. As shown in fig. 9, the left end of the left main rotating shaft 241, which is used as the first end of the main rotating shaft 24, extends leftward, and passes through the left ring 101 to be fixedly connected with the balance weight 6 at the center of the balance weight 6, so that the balance weight 6 is fixedly connected with the left mounting block 11 (see fig. 5), and the balance weight 6 is also fixedly connected with the storage box 13. A position of the balance weight 6 near the circumference is provided with a position of a detent (not shown in the figures because it is blocked by the auxiliary rotation shaft 7 parallel to the main rotation shaft 24), as shown in fig. 8 and 9, the auxiliary rotation shaft 7 penetrates through the auxiliary rotation body 5 and then sinks into the detent, so that the balance weight 6 is rotatably connected with the auxiliary rotation body 5 through the auxiliary rotation shaft 7, and the storage box 13 is also rotatably connected with the auxiliary rotation body 5 through the auxiliary rotation shaft 7. It is conceivable that if the auxiliary rotating shaft 7 is disengaged from the detent (described in detail below), the weight 6 is disengaged from the auxiliary rotating body 5, and the storage box 13 can freely rotate about the rotating shaft 24.

As shown in fig. 10, a distance L3 between the sub-rotary shaft 7 and the left main rotary shaft 241 (i.e., a distance from the main rotary shaft 24) is equal to a distance L1 between the horizontal sub-axis 23 and the horizontal main shaft 2, and a distance L4 between the sub-rotary shaft 7 and the horizontal sub-axis 23 is equal to a distance L2 between the main rotary shaft 24 and the horizontal main shaft 2. Therefore, the four line segments of L1, L2, L3 and L4 form a parallelogram, and the horizontal main axis 2, the horizontal secondary axis 23, the main rotating shaft 24 and the secondary rotating shaft 7 are located at four vertexes of the parallelogram. When the rotating wheel 1 rotates clockwise by 30 degrees, the balanced transportation mechanism is in the state shown in fig. 11 and 12, and although the parallelogram formed by the four line segments of L1, L2, L3 and L4 is deformed, the horizontal main axis 2 and the horizontal secondary axis 23 are fixed, so that the L1 is fixed and kept horizontal. The parallelogram property makes L3 be parallel to L1 all the time, so L3 is kept horizontal all the time, so that the flat box 13 keeps a flat state all the time in the process of circular motion. The embodiment can also be changed as follows: both L1 and L3 incline, and the storage box 13 is flat, and because L3 is always parallel to L1, the inclination degree of L1 and L3 is always unchanged in the deformation process, so that the storage box 13 can be kept flat all the time.

Since the auxiliary shaft 7 is made of a magnetically attracted material, the electromagnet 22 can apply a magnetic force to the auxiliary shaft 7 at the bottom of the circular motion path to disengage the auxiliary shaft 7 from the detent (mentioned above, and described in detail below), so that the balance weight 6 is disengaged from the auxiliary rotation body 5, and the storage box 13 can freely rotate around the main shaft 24. As shown in fig. 3 and 13, the right ring 102 has six rotating blocks 17 uniformly arranged around the right side thereof, and one of the rotating blocks 17 is taken as an example for description. The right end of the right main rotating shaft 242 as the second end of the main rotating shaft 24 extends rightward, and penetrates through the right ring 102 and then is fixedly connected with the rotating block 17 at the center of the rotating block 17, so that the rotating block 17 is fixedly connected with the right mounting block 12 (see fig. 6), the rotating block 17 is also fixedly connected with the storage box 13, and the rotating block 17 follows the storage box 13 to perform circular motion. The rotating block 17 is provided with a driving groove 18, and a strip-shaped driving piece 19 can be sunk into the driving groove 18. The driving member 19 is fixed at a position corresponding to the bottom of the circular motion path of the rotating block 17, the driving member 19 is connected to a motor 21 located beside the horizontal main shaft 25 through a timing belt mechanism 20, and the motor 21 can drive the driving member 19 to rotate at the aforementioned position. The rotary block 17 and the rotary drive element 19 together form a tilting mechanism. As shown in fig. 13, when one of the storage boxes 13 moves to the bottom of the circular motion path, the driving member 19 sinks into the driving groove 18 of the rotating block 17 connected to the storage box 13, and at the same time, the electromagnet 22 disengages the sub-rotating shaft 7 located at the bottom of the circular motion path from the detent, so that the storage box 13 located at the bottom of the circular motion path can freely rotate around the main rotating shaft 24. Subsequently, the driving member 19 in the sinking driving groove 18 is driven by the motor 21 to rotate, so that the driving rotating block 17 rotates to drive the storage box 13 to rotate, the cover 131 hinged at the edge of the top opening of the storage box 13 is automatically opened under the action of gravity, the balance transportation mechanism is changed into the state shown in fig. 13, and the articles contained in the storage box 13 are poured out.
