A plurality of brackets 4 are mounted on the two sets of transmission chains 3, the length direction of the brackets 4 is perpendicular to the direction of movement, and the two ends of the brackets 4 are respectively fixed to the transmission chains 3 on both sides, and rotate synchronously with the transmission chains 3. The brackets 4 also have at least one pair of brackets 41, and the brackets 41 on the multiple brackets 4 are aligned in the direction of movement and are used to carry solar cells, so that the solar cells and the brackets 4 move synchronously.

[0032] Each transmission wheel 2 is installed independently, and the transmission wheels 2 on the same side are only subjected to the transmission effect of the transmission chain 3 to achieve synchronous rotation. Specifically, since each transmission chain 3 is wound with multiple transmission wheels 2, including a driving wheel connected to the output assembly 10, and a driven wheel other than the driving wheel. In the present application, the symmetrically distributed driving wheels are designed to be disconnected, that is, there is no need to use a transmission shaft system for connection; at the same time, the symmetrically distributed driven wheels also need to be designed to be disconnected, and no transmission shaft system is used for connection to avoid the problem of asynchronous transmission on both sides; further, based on the power output of the power source 1, the transmission wheels 2 on the same side only need to be subjected to the transmission effect of the transmission chain 3 to achieve synchronous rotation.

[0033] Regarding the power source 1, the utility model provides the following implementation modes:

[0034] Example 1

[0035] like Figure 1 , Figure 2 As shown, the power source 1 is constructed as a single power drive, including a driving part 11, a first transmission part 12 and a second transmission part 13; the driving part 11 adopts a motor, and the output end of the motor is connected to the input end of the first transmission part 12; the first transmission part 12 is arranged in one group, and the second transmission part 13 is symmetrically arranged in two groups; wherein, the output end of the first transmission part 12 is respectively connected to the input end of the two groups of second transmission parts 13, and the power is evenly transmitted to the second transmission part 13; the two groups of second transmission parts 13 are respectively constructed into two groups of output components 10, and the output ends of the output components 10 are respectively connected to the transmission wheels 2 on the same side.

[0036] Specifically, in this embodiment, the first transmission part 12 adopts a combination of a synchronous wheel and a synchronous chain, and the output end of the motor is connected to one side of the synchronous wheel, thereby realizing the connection between the motor output end and the input end of the first transmission part 12; the other side of the synchronous wheel is connected to the transmission shaft.

[0037] The second transmission part 13 adopts a combination of synchronous wheels and synchronous chains, and two groups are set. The two side ends of the transmission shaft are respectively connected to one side of the synchronous wheels in the second transmission part 13, thereby realizing the connection between the output end of the first transmission part 12 and the input end of the second transmission part 13; the other side of the synchronous wheel in the second transmission part 13 is connected to the transmission wheel 2.

[0038] Example 2

[0039] like Figure 3 As shown, the power source 1 is configured as a single power drive, including a driving part 11 , a first transmission part 12 and a second transmission part 13 .

[0040] In this embodiment, the first transmission part 12 adopts a pair of meshing bevel gears; the second transmission part 13 adopts a combination of a synchronous wheel and a synchronous chain.

[0041] Of course, in other embodiments, the first transmission part 12 and the second transmission part 13 may also be a pair of meshing spur gears or helical gears.

[0042] Example 3

[0043] like Figure 4 As shown, the power source 1 is constructed as a dual-power drive, including two sets of driving parts 11. The driving parts 11 use motors and respectively drive any driving wheel 2 around which the corresponding side transmission chain 3 rotates.

[0044] In this embodiment, the driving part 11 is directly connected to the transmission wheel 2 , and thus the output shaft of the driving part 11 is configured as an output assembly 10 .

[0045] Example 4

[0046] like Figure 5 As shown, the driving part 11 and the transmission wheel 2 are connected to each other by a third transmission part 14. Two groups of the third transmission parts 14 are provided, and the two groups of the third transmission parts 14 are respectively configured to form an output assembly 10 and are symmetrically arranged. The third transmission part 14 adopts a combination of a synchronous wheel and a synchronous chain. Of course, in other embodiments, the third transmission part 14 can also adopt a pair of meshing gears.

[0047] In summary, in the present invention, for a chain-type sintering furnace, a symmetrically distributed output assembly 10 is used to transmit power. Through the output of the driving unit 11, the power can be evenly transmitted to the transmission wheels 2 on both sides, and the problem of uneven transmission of the transmission chains on both sides can be avoided during long-term use. In combination with the above embodiments, it can be seen that the power source 1 can be driven by either a single power source or a dual power source, and the selection of the transmission unit is diverse, and the power can be effectively transmitted to the output assembly 10.
