[0042] The protective mechanism is arranged above the culture tray 6, and comprises a fixed cylinder 13 movably sleeved on the outer periphery of the connecting shaft 18, a movable sleeve 17 movably sleeved on the outer periphery of the fixed sleeve 13, two mounting rings 15 arranged on the outer periphery of the movable sleeve 17, and a protective net arranged on the outer periphery of the mounting ring 15; the mounting ring 15 is coaxially arranged with the movable sleeve 17, and the inner diameter of the mounting ring 15 is greater than the outer diameter of the movable sleeve 17; the protective net comprises two fixed shafts 12 fixed on the outer periphery of the mounting ring 15, a fixed ring 9 fixed on the two fixed shafts 12, and an intercepting net 10 arranged on the inner ring of the fixed ring 9; the two fixed shafts 12, the fixed ring 9 and the mounting ring 15 jointly form a sector space, and the intercepting net 10 is filled in the sector space; the fixed ring 9 is coaxially arranged with the mounting ring 15, the included angle between the two fixed shafts 12 is 180 degrees, and a spacing is arranged between the two fixed shafts 12 of the two protective nets, and the width of the spacing is not less than the width of the first notch 8; the top of the fixed cylinder 13 is fixedly connected with the bottom surface of the second movable rod 4; the inner ring of the mounting ring 15 is rotationally connected with the outer periphery of the movable sleeve 17 through a rotating shaft 22; the second movable rod 4 is provided with a connecting assembly for driving the movable sleeve 17 to move upward when the connecting shaft 18 moves away from the fixed rod 2; the connecting assembly comprises a guide wheel 11 fixed on the bottom surface of the second movable rod 4 and a pull rope 14 fixed on the top of the movable sleeve 17; the other end of the pull rope 14 passes through the guide wheel 11 and is fixedly connected with a fixed sleeve 5 sleeved on the outer periphery of the second movable rod 4; when the culture tray 6 is moved to the side away from the fixed rod 2, the pull rope 14 is gradually unfolded; when the pull rope 14 is taut, the movable sleeve 17 above the culture tray 6 moves upward under the pulling of the pull rope 14, so as to drive the two protective nets to be lifted upward; conversely, when the culture tray 6 is moved to the side close to the fixed rod 2, the pulling force of the pull rope 14 gradually decreases, and the movable sleeve 17 gradually falls under the action of gravity during the process that the culture tray 6 continues to move close to the fixed rod 2, until the protective nets are overlapped on the top of the culture tray 6.

[0043] The protective mechanism further comprises a linkage assembly arranged on one side of the fixed cylinder 13 and used for driving the mounting ring 15 to rotate when the movable sleeve 17 is lifted and lowered; the linkage assembly comprises two racks 16 fixed on the bottom surface of the second movable rod 4 and two gears 21 respectively sleeved on the outer peripheries of the two rotating shafts 22; the two rotating shafts 22 are not fixedly connected with the same mounting ring 15; the two racks 16 are respectively engaged with the two gears 21; when the movable sleeve 17 moves upward, the mounting ring 15 moves upward synchronously; the gears 21 positively rotate while moving upward along the surfaces of the racks 16, so as to drive the protective nets to be turned upward; conversely, when the movable sleeve 17 descends, the protective nets can be driven to be turned downward.

[0044] The implementation principle of the embodiment is that when breeding, mulberry leaves are laid in the placing disc 6, and then silkworms are placed on the mulberry leaves. When breeding, the plurality of breeding units are arranged in order from top to bottom, and the fixing rod 2 is clamped in the first notch 8, so that the breeding disc can be prevented from rotating. When it is necessary to operate a certain breeding unit, the breeding unit can be pulled out to the outside until the fixing rod 2 moves to the outside of the first notch 8. At this time, half of the breeding disc 6 in the breeding unit moves to the outside of the breeding unit directly above, and then the breeding disc 6 can be rotated to check or arrange the mulberry leaves or silkworms in the breeding disc 6. After the arrangement is completed, the breeding disc 6 can be pushed back to the original position.

[0045] When the breeding disc 6 is pulled out to the outside, the protective nets arranged above the breeding unit are also opened. When the breeding disc 6 moves away from the fixing rod 2, the pull rope 14 is gradually unfolded. When the pull rope 14 is taut, the movable sleeve 17 arranged above the breeding disc 6 moves upward under the pulling of the pull rope 14, so that the two protective nets can be lifted upward. While the movable sleeve 17 moves upward, the mounting ring 15 moves upward synchronously, and the gear 21 moves upward along the surface of the rack 16 and rotates in the positive direction, so that the protective nets are turned upward. Conversely, when the breeding disc 6 moves toward the fixing rod 2, the pulling force of the pull rope 14 gradually decreases. Under the action of gravity, the movable sleeve 17 gradually falls downward in the process that the breeding disc 6 continues to move toward the fixing rod 2, and the protective nets are turned downward until the protective nets are overlapped on the top of the breeding disc 6.

[0046] Embodiment 2

[0047] In combination with Figure 1 , Figure 3 , Figure 4 and Figure 5 , the embodiment is further improved on the basis of the embodiment 1. The bottom surface of the breeding disc 6 is fixed with a collecting hopper 7. The collecting hopper 7 is rotatably sleeved on the outer periphery of the connecting shaft 18. The outer periphery of the connecting shaft 18 is sleeved with a limiting ring 20. The bottom of the collecting hopper 7 abuts against the top surface of the limiting ring 20. The limiting ring 20 can support the collecting hopper 7. A second notch is arranged on the collecting hopper 7 below the first notch 8. The width of the second notch is the same as that of the first notch 8. The length of the second notch is the same as that of the first notch 8. The two long sides of the second notch are both arranged as open ports communicating with the inside of the collecting hopper 7. The outer periphery of the connecting shaft 18 is fixed with a scraper 19 arranged in the radial direction of the collecting hopper 7. The bottom surface of the scraper 19 abuts against the bottom surface of the collecting hopper 7. One end of the scraper 19 abuts against the inner circle of the collecting hopper 7. The open port arrangement of the second notch makes the silkworm sand or residue of mulberry leaves in the collecting hopper 7 easy to be discharged.

[0048] The principle of the embodiment is that the excrement of silkworms or the residues of mulberry leaves in the breeding tray 6 fall into the collecting hopper 7 through the mesh holes on the breeding tray 6, and when the excrement and residues of mulberry leaves in the collecting hopper 7 are collected, the breeding tray 6 is rotated, the connecting shaft 18 does not rotate, the scraper 19 can scrape the excrement or residues of mulberry leaves on the bottom of the collecting hopper 7 when the breeding tray 6 rotates, and the scraped residues can be discharged from the second notch when the second notch passes the scraper 19, thereby facilitating the collection of the excrement or residues of mulberry leaves in the collecting hopper 7 by the operator.

[0049] The above-mentioned embodiments are only the preferred embodiments of the present application, and cannot be used to limit the protection scope of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the protection scope of the present application.
