[0082] In some optional embodiments, the scraper assembly includes a plurality of scrapers 6 fixedly connected to both sides of the chain 2 , and the bottoms of the scrapers 6 located on both sides of the chain 2 are in sliding contact with the tops of the two conveying plates 5 respectively.

[0083] In some optional embodiments, the lifting assembly includes a second motor 7 fixedly connected to the box plate 4, a screw rod 8 is fixedly connected to the output shaft of the second motor 7, a transmission nut 9 is threadedly sleeved on the screw rod 8, the transmission nut 9 is fixedly connected to the fixed plate 26, a slide groove 10 is opened on the box plate 4, the fixed plate 26 is slidably connected to the slide groove 10, and a tensioning wheel 3 is arranged between the two fixed plates 26.

[0084] The wire box 32 is installed at the bottom end of the conveying plate 5 , and the wires 31 are connected to the second motor 7 through the wire box 32 to control the operation of the second motor 7 .

[0085] When in use, the tension of the chain 2 is adjusted by driving the screw 8 to rotate through the second motor 7, thereby driving the transmission nut 9 and the screw 8 to rotate threadably, so that the fixed plate 26 slides in the slide groove 10, and the tensioning wheel 3 rises. After the tensioning wheel 3 rises, the tension on the chain 2 is increased. Similarly, after the tensioning wheel 3 drops, the tension on the chain 2 is reduced.

[0086] In some optional embodiments, a first rotating shaft 11 is rotatably connected to any fixed plate 26 in the support module 1, and the first rotating shaft 11 is fixedly connected to the tensioning wheel 3.

[0090] By setting up multiple first motors 14 to drive, a multi-motor multi-point joint driving mode is implemented to achieve higher power, higher efficiency and better control, and solve the problems of motor overload and heat.

[0091] When the device needs to be moved, the tensioning wheel 3 is first driven down by the second motor 7 to loosen the chain 2. At this time, the chain 2 can be disengaged from the tensioning wheel 3 and the driving wheel respectively, thereby releasing the restrictions on the tensioning wheel 3 and the driving wheel. Then the box plate 4 is moved to both sides to pull the first rotating shaft 11 out of the first slot and the second rotating shaft out of the second slot, thereby separating the first rotating shaft 11 and the second rotating shaft from one box plate 4 respectively. At this time, the two box plates 4 are taken out from both sides of the chain 2 respectively, thereby realizing the disassembly of one module without interfering with the chain 2.

[0092] In some optional embodiments, a plurality of first positioning grooves 15 are formed at one end of the box plate 4, and a plurality of first positioning blocks 16 are fixedly connected to the other end, and the first positioning blocks 16 on the box plate 4 in the support module 1 are clamped with the first positioning grooves 15 on the box plate 4 in the adjacent support module 1;

[0094] During installation, the first positioning block 16 is extended into the first positioning groove 15 and positioned by the positioning column 18, thereby realizing the assembly of two adjacent support modules 1, so that they are connected as a whole, avoiding vibration, movement and dislocation during use, and improving the stability of the device.

A limiting groove 25 slidably connected to the limiting block 24 is opened on the outer wall of the box plate 4. When the limiting block 24 extends into the limiting groove 25, the positioning column 18 extends into the first positioning hole 17. When the limiting block 24 rests on the outer wall of the box plate 4, the positioning column 18 extends out of the first positioning hole 17.

[0097] Under the elastic force of the spring 22, the limit block 24 extends into the limit groove 25, and the positioning column 18 extends into the first positioning hole 17 to achieve assembly; when disassembly is required, the handle 19 is stretched to pull the limit block 24 and the positioning column 18 out of the limit groove 25 and the first positioning hole 17 respectively, and then the rotating rod 23 is rotated to rotate the limit block 24 to be misaligned with the limit groove 25, and the handle 19 is released. Under the elastic force of the spring 22, the limit block 24 is against the outer wall of the box plate 4.

[0098] When installing the present invention, first install the two support modules 1 located at the end, put the chain 2 on the two first sprockets and engage them, and then install the several support modules 1 located in the middle; when installing the middle support module 1, first insert the first rotating shaft 11 and the second rotating shaft into the first slot and the second slot respectively, so as to realize the installation of the two box plates 4, and then insert the first positioning block 16 on the box plate 4 into the first positioning groove 15 on the adjacent support module 1, and then rotate the rotating rod 23 to make the limit block 24 rotate to face the limit groove 25, release the handle 19, and under the elastic force of the spring 22, the limit block 24 extends into the limit groove 25, and at the same time, the positioning column 18 extends into the first positioning hole 17, so as to realize the assembly of the two adjacent support modules 1.

[0099] After the middle supporting modules 1 are assembled in sequence, the chain 2 is tensioned by the tensioning wheel 3 , the chain 2 is meshed with the tensioning wheel 3 , and the driving wheel is also meshed with the chain 2 .

[0100] When disassembly is required, first loosen the chain 2 to cancel the engagement with the tension wheel 3 and the driving wheel, then disassemble the two adjacent support modules 1, and then disassemble the two box plates 4 in the support module 1.

[0101] Example 2

[0103] A second magnetic strip 29 is fixedly connected to the inner top wall of the upper accommodating groove 27. When the first positioning block 16 located above is in a horizontal direction, the first magnetic strip 28 on the first positioning block 16 is magnetically attracted to the second magnetic strip 29. When the first positioning block 16 is rotated downward to a vertical direction, the first magnetic strip 28 is separated from the second magnetic strip 29, and the first positioning block 16 remains vertical under the action of gravity and retracts into the accommodating groove 27.

[0104] A third magnetic strip 30 is fixedly connected to the inner wall of the receiving groove 27 below. When the first positioning block 16 below is in a horizontal direction, the side wall of the first positioning block 16 contacts the bottom of the receiving groove 27, so that the first positioning block 16 is in a horizontal state under the action of gravity. When the first positioning block 16 below is rotated upward to a vertical direction, the first magnetic strip 28 is magnetically attracted to the third magnetic strip 30, so that under the magnetic state, the first positioning block 16 remains vertically retracted into the receiving groove 27.

[0105] When the device is moved, the first positioning block 16 is retracted into the receiving groove 27 to avoid being damaged.
