At the center position on one side of the auxiliary slot 504, a support pin 506 is fixedly provided, and one end of the support pin 506 is adaptively inserted into the auxiliary slot 504.

[0022] Regarding the setting of the conveying mesh chain in this solution, when it needs to be removed, there is no need to remove the first sleeve 1 and the second sleeve 2 connected to it, that is, there is no need for overall removal. When the conveying mesh chain needs to be disassembled as a whole, it is only necessary to release the fixation of the filter plate body 601 and the chain by the connecting fitting and the limiting fitting, that is, release the connection of one pair of adjacent filter plate bodies 601, and then the entire conveying mesh chain can be removed. One side of the filter plate body 601 in the filter conveying chain assembly is provided with a docking convex part 602, the other side is provided with a docking concave part 603, and a docking sleeve 604 is arranged at the end position of the docking convex part 602. The filter plate body 601 is also provided with a docking sleeve 604 at the end of the side provided with the docking concave part 603; the outer chain plate 605, the inner chain plate 606 and the chain sleeve 607 form a transmission chain, and the transmission chain is connected to the filter plate body 601 through the provided connecting fitting. One end of the connecting pin shaft 701 in the connecting fitting is fixedly provided with a limiting disc 702. Through holes 705 are symmetrically arranged in the limiting disc 702, and receiving grooves 703 are equidistantly arranged on the side wall of the end of the limiting disc 702 connected to the connecting pin shaft 701. The first auxiliary balls 704 are placed in the receiving grooves 703. The receiving grooves 703 are arranged in an equidistant annular shape on the limiting disc 702. First auxiliary sleeve grooves 707 are equidistantly arranged in the limiting cover plate 706, and the first auxiliary sleeve grooves 707 and the receiving grooves 703 are arranged at corresponding positions and have the same number of sets. Connecting screw grooves 708 are symmetrically arranged on one side of the limiting cover plate 706. The limiting cover plate 706 and the limiting disc 702 are attached to each other and are connected and fixed by the provided connecting screw 709.

[0023] In order to limit the connection between the filter plate body 601 and the drive chain, in this solution, a limit fitting and a connection fitting are used in cooperation by arranging a limit fitting at the other end of the connection pin shaft 701. Among them, the connection thread 801 in the limit fitting is arranged at the side wall position of one end of the connection pin shaft 701, and a fastening slot 802 is also arranged at the position where the connection thread 801 is arranged. The fastening slot 802 is arranged in a ring shape. The limit collar 803 is sleeved on the connection pin shaft 701, and a threaded cavity 804 is arranged at one end of the limit collar 803. Second auxiliary sleeve slots 805 are equidistantly arranged in the threaded cavity 804, and second auxiliary balls 806 are placed in the second auxiliary sleeve slots 805. The limit cover body 807 is sleeved on the connection pin shaft 701, and a threaded convex part 808 is fixedly arranged at one end of the limit cover body 807. The threaded convex part 808 is threadedly connected with the threaded cavity 804 in a matching manner, and an annular groove 809 is arranged on the end face of the threaded convex part 808; among them, the connection pin shaft 701 sequentially passes through the outer side link plate 605, the inner side link plate 606, the chain sleeve 607, and the inner side link plate 606 and the outer side link plate 605 at the other end of the chain sleeve 607, then passes through the docking sleeve 604 in the filter plate body 601, and finally passes through the outer side link plate 605, the inner side link plate 606, and the chain sleeve 607 on the other side of the filter plate body 601, and the connection pin shaft 701 is tightened, so that the limit disc 702 at one end of the connection pin shaft 701 limits the outer side link plate 605 on one side of the drive chain, and then the limit fitting is installed.

[0024] In order to improve its stability, in this solution, a fastening structure is arranged for limit and firmness, that is, the internal thread fastening cap 901 in the fastening structure is threadedly connected with the connection thread 801 on the side wall of one end of the connection pin shaft 701 in a matching manner. Rotation auxiliary ridges 903 are symmetrically and fixedly arranged on the outer side wall of the internal thread fastening cap 901. A threaded through hole 902 is arranged in the internal thread fastening cap 901, and the threaded through hole 902 is threadedly connected with the locking screw 904 in a matching manner. One end of the locking screw 904 is clamped with the fastening slot 802 in a matching manner; that is, the internal thread fastening cap 901 is threadedly connected with the connection thread 801 on the side wall of one end of the connection pin shaft 701. After the internal thread fastening cap 901 is tightened, at this time, the threaded through hole 902 arranged in the internal thread fastening cap 901 is aligned with the notch of the fastening slot 802, and then the locking screw 904 is threadedly connected with the threaded through hole 902, so that one end of the locking screw 904 is stuck in the fastening slot 802.

[0025] When disassembling the connecting pin 701, it is first necessary to release the limiting work of the fastening structure, that is, it is necessary to first release the lock of the internal thread fastening cap 901, rotate the locking screw 904, so that one end of the locking screw 904 is separated from the fastening slot 802, and then release the lock of the internal thread fastening cap 901, and then rotate the internal thread fastening cap 901 to release the limit of the limiting collar 803 by the internal thread fastening cap 901, and then remove the limiting collar 803, and finally pull out the connecting pin 701. At this time, the connection between the two adjacent filter plates 601 is released, and the conveyor chain can be disassembled, which is convenient to operate.

[0026] If it is necessary to disassemble and replace a certain section or part of the filter plate 601, it is only necessary to disassemble the connecting pin 701 connecting the corresponding filter plate 601 to it, which makes its maintenance more flexible. In this solution, the use of the limiting disc 702 and the limiting collar 803, through the provision of the first auxiliary ball 704 and the second auxiliary ball 806, also has a corresponding friction protection effect on the outer chain plate 605 during transmission, thereby increasing its service life.

[0027] In order to further improve the maintenance work of the conveyor network chain, save maintenance time, and meet the needs of its food waste transportation work, this solution uses connecting accessories and limit accessories to connect each pair of adjacent filter plates 601. The purpose is that during actual maintenance work, a certain section or a certain filter plate 601 can be replaced according to actual needs, and the replacement is convenient; on the other hand, compared with the traditional one with only one disconnectable connector, there is no need to spend time looking for the corresponding disconnect connector, that is, the existing conveyor chain usually also has a disconnectable connector, which is also for the convenience of subsequent replacement work, but in actual operation, it generally takes a certain amount of time to find a disconnectable connector; therefore, this solution has better working flexibility.

[0028] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
