[0028] In use: when disassembling the steel pipe, the side top pressing bolt is unscrewed, the steel pipe is rolled out of the U-shaped slot, and the steel pipe is rolled to the connecting chain on the disassembly guide slope, the steel pipe is lifted and erected, and the disassembly of the steel pipe is completed. Although the disassembly and assembly of the steel pipe still needs to stop and disassemble the top pressing bolt, since the bolt fixing position is inside the baffle, the baffle on both sides will not block the bolt position, and all the bolts can be disassembled at each stop. At the same time, there is no need to move the steel pipe to be disassembled to the rotating position, since the steel pipe between the two baffles can also be rolled out of the gap and disassembled, and the steel pipe in the blocked part can be disassembled between the two baffles, so the process does not need frequent intermittent start and stop, as shown in Figure 5 , and there is no need to leave space on both sides for the extraction and feeding of the steel pipe, as shown in Figure 6 . When installing the steel pipe, the steel pipe is also horizontally placed on the connecting chain, rolled into the inclined U-shaped slot of the fixed chain along the disassembly guide slope, and then screwed into the side hole of the baffle through the top pressing bolt, so as to press and clamp the steel pipe on the outer side of the position, prevent the steel pipe from falling off, or directly screwed into the corresponding thread hole on the steel pipe, complete the installation and fixation of the steel pipe. When changing the specification of the steel pipe, the radius of the arc of the bottom of the inclined U-shaped slot is selected and adjusted according to the size of the steel pipe to be installed, and a length of the chain unit can be conveniently replaced as a whole through the movable pin.

[0029] The rhizome crop harvester chain facilitating the disassembly and assembly of the conveying steel pipe overcomes the inconvenience of intermittent operation adjustment during the disassembly and assembly of the conveying steel pipe of the existing rhizome crop harvester, and the requirement of large side space for the operation process. Through the semi-open structure design of the fixed part of the chain, the disassembly and assembly of the conveying steel pipe can be conveniently carried out, and the frequent and intermittent start and stop of the conveying part during the operation process is not required, and the side space for the extraction and feeding of the steel pipe is not required, which improves the efficiency of the disassembly and assembly and reduces the limitation of the disassembly and assembly conditions.
