[0028] Example:

[0029] The embodiment of the present application discloses a mechanism in which the upper and lower belt conveyors share a common drive system. Figure 1 、 Figure 2 and Figure 3 The two gears are connected to each other by a shaft 3, and the two gears are connected to each other by a shaft 3.

[0030] One end of the motor 6 housing is fixedly connected to a mounting plate, which is an "L"-shaped plate structure, and one end of the bottom of the mounting plate is fixedly mounted on the outer surface of the front frame plate 2;

[0031] The drive adjustment assembly includes an adjustment slot 11 that is opened through the inner cavity of the front end frame 2, and a displacement block 12 is slidably sleeved on the inner wall of one side of the adjustment slot 11. One end face of the displacement block 12 is fixedly connected to the connecting column 10, and an electric push rod 13 is fixedly connected to one side wall of the displacement block 12. The non-driving end of the electric push rod 13 is fixedly installed on the inner wall of the other side of the adjustment slot 11. The drive adjustment assembly also includes a slide slot 14 opened in the middle of the upper and lower sides of the displacement block 12. The inner walls of the two slide slots 14 are both slidably sleeved with slide rails 15, and the two slide rails 15 are respectively fixedly installed on the upper and lower inner walls of the adjustment slot 11;

[0032] Among them, under the joint action of the adjustment slot 11, displacement block 12, electric push rod 13, slide slot 14 and slide rail 15 in the drive adjustment component, the connecting column 10 is fixedly connected, and the stable support and positioning effect of the third gear 7 is indirectly achieved. In addition, the horizontal position of the third gear 7 can be indirectly adjusted through the drive adjustment action of the electric push rod 13, thereby solving the extended tensioning effect of the slack phenomenon caused by long-term use of the chain 8.

[0033] See also Figure 1 and Figure 2 , both ends of the outer wall of the other side of the two sets of belt conveyor bodies 1 are fixedly connected with support plates 16, and the support plates 16 at both ends are in the same horizontal plane as the bottom of the frame plates 2 at both ends. The connection between the frame plates 2 at both ends and the support plates 16 on one end face is vertically fixed with two cross beams 17. The four cross beams 17 are respectively in contact with both sides of the bottom of the two sets of belt conveyor bodies 1. A control panel 18 is fixedly installed at one corner of the upper end of the front frame plate 2. The outer surface of the control panel 18 is provided with a display screen and buttons. The control panel 18 is electrically connected and controlled with the motor 6 and the electric push rod 13 through wires, and the connection control function of the control panel 18 can be achieved through programming. It is a prior art and will not be described in detail here.

[0034] The working principle of this embodiment is as follows: when in use, the whole is in a complete assembled state, wherein the two sets of belt conveyor bodies 1 are both existing mature belt conveyor structures, which generally include "main frame plate, transmission belt and multiple rollers", and the two shafts 3 are fixedly connected to the extended end of a "roller" at the end of the two sets of belt conveyor bodies 1, that is, when the shafts 3 passively rotate, they can indirectly drive the belt conveyor bodies 1 to operate and horizontally transport materials;

[0035] When the motor 6 is controlled to start, it drives the second gear 5 to rotate. At the same time, the meshing transmission of the second gear 5 and the outer wall of the first gear 4 and the third gear 7 uses the chain 8 shared by the second gear 5, thereby indirectly making the first gear 4, the second gear 5, and the third gear 7 rotate synchronously and in the same direction, so that the operation and transmission of the two sets of belt conveyor bodies 1 can be realized under the rotation of the two shafts 3. When the third gear 7 rotates passively, its central inner cavity is connected with the I-shaped shaft 9 through the rotation sleeve, and the outer wall of the I-shaped shaft 9 is limited and rotated to achieve the tensile restriction of the isosceles triangle state of the chain 8.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
