Description

Technical Field

[0001] The utility model relates to the technical field of expanding and multiplying Lepidoptera larvae, and in particular to a feeding tray conveyor line used for expanding and multiplying Lepidoptera larvae. Background Art

[0002] The larvae of Lepidoptera are widely distributed, with the most abundant species in the tropics. Most larvae of these species harm various cultivated plants. Larger ones often eat all the leaves or bore into branches. Smaller ones often roll up leaves, attach leaves, form sheaths, spin silk webs, or bore into plant tissues to feed. Adults often supplement nutrition with nectar, or their mouthparts degenerate and they no longer feed, so they generally do not cause direct harm. Most butterflies are diurnal, while moths fly at dusk, dawn, and at night.

[0003] Lepidoptera larvae have very important economic significance in agriculture, forestry and horticulture, and are one of the key learning contents. To prevent and control Lepidoptera larvae, one is to use insecticidal lamps and sweet and sour liquid to lure and kill adult insects; the second is to protect and utilize natural enemies such as parasitic wasps; the third is chemical control. In the process of raising universal Lepidoptera larvae, trays are needed to fill feed, and the trays are used to raise universal Lepidoptera larvae; there are attempts in the prior art to transport trays in a semi-mechanized manner, but the efficiency is relatively low, and it still relies heavily on manual labor, resulting in high costs and low work efficiency.

This arrangement can greatly extend the automated time for conveying a stack of pallets 4, and reduce the time required to frequently place a stack of pallets 4 on the first conveyor line, allowing operators to free up extra time to do other work.

[0069] In a specific implementation manner, Fig.10 As shown, the tray downstream transfer unit includes:

[0070] The downstream conveyor belt 63 and the third motor driving it to rotate extend along the width direction and the upstream section of which is located below the support platform 2 at a position corresponding to the through-port 3.

The filling section is correspondingly located above the pallet positioned by the positioning block 65. The PLC controller is electrically connected to the third motor, the pallet positioning block cylinder 64 and the third pallet sensor 66.

[0071] The setting of the positioning block 65 can realize the precise positioning of the tray on the downstream conveyor belt 63, so as to facilitate the accuracy of subsequent filling.

[0072] The two pallet positioning block cylinders 64, the two positioning blocks 65 and the third pallet sensor 66 form a group of positioning units.

Each group of the filling parts includes a filling platform 64 erected above the downstream conveyor belt 63 and corresponding to the position of the pallet to be filled. The filling platform 64 is used to place the filling equipment.

[0074] The end pallet sensor at the end of the second conveyor line 44 is used to detect whether there is a stack of pallets 4 at this position. If yes, a signal is given to enable the PLC controller to control the fourth cylinder 53 to drive the vertical baffle 54 to resist the stack of pallets 4. If no, a signal is given to enable the PLC controller to control the first conveyor line 31 and the relevant components of the second conveyor line 44 to realize the conveyance of a stack of pallets 4. Specifically: the first extrusion plate cylinder 42 controls the first extrusion plate to return to its position so that it does not squeeze the last stack of pallets 4. At this time, the first cylinder 37 drives the vertical moving platform 38 to move upward to the first gap 34 to transfer The pallet plate 40 lifts the last stack of pallets 4, and the second cylinder 39 drives the transfer pallet plate 40 to move toward the second conveyor line 44, so that the stack of pallets 4 moves to above the second conveyor line belt 46. At this time, the third cylinder 51 drives the two lifting plates 52 to move upward to lift the stack of pallets 4. At this time, the transfer pallet plate 40 returns to its original position, and then the two lifting plates 52 move downward, so that the stack of pallets 4 is located on the two second conveyor line belts 46. At this time, the second motor is controlled to make the second conveyor line belts 46 rotate to transport the stack of pallets 4 to the end of the second conveyor line 44.

[0075] The conveying process of a plurality of stacks of pallets 4 on the first conveyor line 31 is as follows: when the first pallet sensor 41 at the very end detects the presence of a pallet, the first squeezing plate cylinder 42 is controlled to drive the first squeezing plate to move toward each other so that it clamps the stack of pallets 4 at the very end; when the first pallet sensor 41 at the second end detects the presence of a pallet, the second squeezing plate cylinder 43 is controlled to drive the second squeezing plate to move toward each other so that it clamps the stack of pallets 4 at the second end; as mentioned above, when the end pallet sensor at the end of the second conveyor line 44 detects that there is no stack of pallets 4 at this position, a signal is given to cause the first squeezing plate cylinder 42 to move toward each other so that it clamps the stack of pallets 4 at the very end. The first squeezing plate is driven back to its position, and then the stack of pallets 4 at the end is started to be transported; when the first pallet sensor 41 at the end detects that there is no pallet, a signal is given to control the second squeezing plate cylinder 43 to drive the second squeezing plate to return, so that the stack of pallets 4 at the second end is transported to the end. At this time, when the first pallet sensor 41 at the end detects that there is a pallet, the first squeezing plate cylinder 42 is controlled again to make the two first squeezing plates move toward each other and then clamp the pallet; similarly, when the first pallet sensor 41 at the second end detects that there is a pallet, the second squeezing plate cylinder 43 is controlled again to make the two second squeezing plates move toward each other and then clamp the pallet.

[0076] The three first conveyor lines 31 are arranged to convey a plurality of stacks of trays 4 on the first conveyor line first, followed by the stacks on the second conveyor line, and finally the stacks on the third conveyor line.

[0077] The process is fully automated, greatly improving efficiency.
