[0037] The use principle of the utility model is as follows:

[0038] As shown in Figure 1 and Figure 5 , the first electric cylinder 21 and the second electric cylinder 22 are each provided with two and are symmetrically arranged on the left and right sides of the support 10 in the conveying direction, before use, the articles are normally conveyed to the discharge position and collected according to the discharge end position of the conveying frame 1, at this time, the first support frame 31 and the second support frame 32 are folded and attached to each other and located above the discharge end position of the conveying frame 1.

[0039] When needed, as shown in Figures 1 to 4 , the first electric cylinder 21 and the second electric cylinder 22 are simultaneously started, wherein, since the third connecting rod 212 is sleeved in the third connecting hole 223, the output end of the first electric cylinder 21 is moved back to the cylinder body direction, drives the second electric cylinder 22 to rotate in the clockwise direction, and the output end of the second electric cylinder 22 is simultaneously extended outward and drives the first support frame 31 and the second support frame 32 to synchronously rotate; in this process, since the first support frame 31 and the second support frame 32 are hingedly connected and the second connecting hole 221 is sleeved on the outside of the second connecting rod 12, the output end of the second electric cylinder 22 is hingedly connected with the first support frame 31, that is, the extension of the output end of the second electric cylinder 22 also drives the first support frame 31 to rotate in the counterclockwise direction.

[0040] At the same time, since the first connecting hole 211 is sleeved on the outside of the first connecting rod 11, with the return of the output end of the first electric top cylinder 21, the first electric top cylinder 21 also synchronously rotates in the clockwise direction, when the second support frame 32 rotates to the horizontal position, the first support frame 31 also rotates to the horizontal position, and the adjacent end faces at the hinged positions of the two support frames are in close contact with each other, at this time, the two electric top cylinders are closed, and the two support frames form an outwardly extending extended section in the discharging direction of the transmission frame 1.

[0041] In order to avoid a large gap in the conveying direction and prevent damage to the articles, a sleeve ring 7 is sleeved on the driving rod and the transmission rod, and the plane on which the upper end wheel surface of the sleeve ring 7 is located is preferably flush with the plane on which the discharging position of the transmission frame 1 is located.

[0042] Finally, the first power motor 43 and the second power motor 53 are simultaneously turned on, the first driving rod 41 drives the first transmission rod 42 to synchronously rotate through the first transmission chain 45 and the second transmission chain 46, and the second driving rod 51 drives the second transmission rod 52 to synchronously rotate through the third transmission chain 55 and the fourth transmission chain 56, so that the articles discharged from the transmission frame 1 continue to be transferred to the position after the extended distance on the second transmission support and the first transmission support.

[0043] After use, the two power motors are closed, and the two electric top cylinders are turned on again to fold the two transmission supports, wherein the output end of the first electric top cylinder 21 extends outward, drives the second electric top cylinder 22 to rotate in the counterclockwise direction, and thereby drives the first support frame 31 and the second support frame 32 to synchronously rotate, the first electric top cylinder 21 also synchronously rotates in the counterclockwise direction, and the output end of the second electric top cylinder 22 returns to the cylinder body direction; in this process, since the first support frame 31 is hingedly connected with the second support frame 32, and the return of the output end of the second electric top cylinder 22 drives the first support frame 31 to rotate in the clockwise direction, so that when the second support frame 32 rotates to the vertical position, the first support frame 31 also rotates to the vertical position, and the two support frames are folded at the vertical position (as shown in the state of Figure 5 At this time, the two electric top cylinders are closed.

[0044] In addition, during use, if the transmission chain needs to be replaced, it only needs to be flipped to open the hole cover 60 to expose the maintenance hole 6, and it can be operated at the position of the maintenance hole 6, and after the replacement is completed, the hole cover 60 can be buckled; it should be noted that in combination with the use state of the two support frames, the hinged positions of the hole cover 60 are preferably close to the hinged ends of the two support frames, so that during the flipping process, the hole cover 60 is always in close contact with the hole opening position of the maintenance hole 6 due to the action of gravity.

[0045] It needs to be explained that in the utility model, the number of the first power motor 43 and the second power motor 53 should be determined according to the specific use, and in the embodiment, the first power motor 43 and the second power motor 53 are each provided with two, so as to ensure the stability of the power transmission.
