Description

Technical Field

[0001] The invention relates to the technical field of plug tray conveying and feeding, and in particular to a multi-layer bed feeding machine for seedling-raising plug trays. Background Art

[0002] Plug tray seedling technology is a modern seedling technology that uses special plug trays of different specifications as containers, peat, vermiculite and other light soil-free substrate materials as seedling substrates, mechanized precision sowing, one hole and one seed, and one-time seedlings. Plug tray seedling technology is a form of factory seedling cultivation. Usually, the plug tray is filled and sown first, and then the plug tray is placed on the seedling vehicle. The seedling vehicle realizes the turnover and transportation of the plug tray, and the plug tray is moved to the digital seedling workshop to realize factory seedling cultivation in the seedling workshop.

[0003] A seedling car is a vehicle specially used for the transportation and turnover of horticultural crop seedlings. It is mainly used for turnover and transportation within the base greenhouse to improve turnover efficiency. The design of the seedling car takes into account the characteristics of horticultural crops. It usually has a multi-layer structure to facilitate the handling and loading and unloading of seedlings of different types of horticultural crops. The seedling car mainly includes a plug tray transfer car and a seedling transfer car; the plug tray transfer car is used to transport the sown plug tray to the germination room, and its height and width are determined according to the size of the plug tray, the space of the germination room, and the number of seedlings. Seedling carts are widely used in the field of vegetable seedling cultivation, especially in intensive seedling factories and seedling factories with relatively complete internal facilities in the base; they are suitable for turnover and transportation in the base greenhouse, which can reduce manual operations and improve work efficiency.

[0004] Compared with traditional seedling raising methods, factory seedling raising technology can shorten seedling raising time, save seed consumption, occupy a small area, is suitable for mechanized operation, saves labor and effort, realizes large-scale production, can artificially control the environment, is not affected by external conditions, can minimize the occurrence of diseases and insect pests, improve the seedling rate and promote uniform and strong seedlings. Since factory seedling raising is unified seedling raising and unified management, it ensures the completion of sowing tasks and the matching of various early and late crops according to plan. It is also conducive to the timely promotion of new varieties and is an important way to achieve good varieties and seedlings.

[0005] Currently, the placement of seedling trays on the seedling-raising cart is mainly completed manually. The operator needs to manually carry the seedling trays and place them on the seedling-raising cart in sequence. Since the seedling-raising cart is a multi-layer structure with several layers of storage platforms, multiple seedling trays can be placed side by side on each storage platform in sequence. Therefore, when loading the seedling trays onto the seedling-raising cart, it is necessary to manually place the seedling trays one by one on the storage platform. After filling one storage platform, then place them on the next storage platform. However, the working method of manually carrying and placing the seedling trays on the seedling-raising cart not only has a large labor intensity, is time-consuming and laborious, but also has a high labor cost and low work efficiency. In addition, when placing the seedling trays on the uppermost several storage platforms of the seedling-raising cart, due to the high height of the storage platform and the mobility of the seedling-raising cart itself, the placement of the seedling trays is difficult, the operation is extremely inconvenient, and there are certain safety hazards.

[0034] This seedling-raising tray multi-layer feeding machine has a high degree of automation. It realizes the conveyance of trays through the tray conveying mechanism, and realizes the pushing of the trays at the discharging end of the tray conveying mechanism conveyed to the tray conveying mechanism through the first tray pushing mechanism, and pushes the trays to the lifting platform. The lifting platform driven by the fourth driving device cooperates with the second tray pushing mechanism to push the trays onto the storage racks of each layer of the seedling-raising cart, so as to realize the automatic conveyance of trays, the synchronous pushing of multiple trays, and the orderly placement of trays on the storage platforms of each layer of the seedling-raising cart.

[0035] When this seedling-raising tray multi-layer feeding machine operates, the first driving device works to drive the conveyor belt to convey the trays. After the trays are conveyed to the discharging end of the transmission frame body, the limit baffle realizes the positioning and blocking of the trays. And after the next conveyed tray abuts against the previous tray, the previous tray realizes the positioning and blocking of the next tray. In this way, along the conveying direction of the trays on the conveyor belt, the trays can be arranged side by side in sequence. When the number of arranged trays reaches the set value, the third driving device works to drive the lifting frame to descend, realizing the descending displacement of the first tray pushing plate. Then, the second driving device works to drive the translation frame and the lifting frame to displace along the direction close to the lifting platform, and realizes the synchronous pushing of multiple side-by-side trays through the first tray pushing plate, and pushes a row of trays onto the lifting platform. After that, the third driving device works to drive the lifting frame to rise and reset. At the same time, the second driving device works to drive the translation frame to reset, so as to realize the reset of the first tray pushing plate; while the first tray pushing mechanism resets, the fourth driving device works to drive the lifting platform to rise or descend to the set height, so that the lifting platform and the corresponding empty-layer storage platform are at the same height. Then, the seventh driving device works to drive the flipping and overlapping plate to be placed on the current storage platform. After that, the sixth driving device works to drive the second tray pushing plate to descend to the pushing position. Finally, the fifth driving device works to drive the pushing frame body to displace. Under the guiding action of the tray guiding channel, the trays on the lifting platform are pushed onto the storage platform of the seedling-raising cart through the second tray pushing plate; after the feeding of the trays on one layer of the storage platform is completed, the seventh driving device works to drive the flipping and overlapping plate to reset. Then, the fourth driving device works to drive the lifting platform to displace to the initial height position. While the lifting platform resets, the sixth driving device works to drive the second tray pushing plate to rise and reset. The fifth driving device works to drive the pushing frame body to reset. When the lifting platform reaches the initial height position, the second tray pushing plate also resets to the replenishing position. At this time, the lifting platform and the conveyor belt are at the same height, and there is a replenishing gap for the trays to pass between the second tray pushing plate and the lifting platform. The next batch of trays can be pushed onto the lifting platform through the first tray pushing mechanism. Repeat the above steps to push the next batch of trays onto the next layer of the storage platform of the seedling-raising cart, and so on.

[0036] Through this multi-layer bed-loading machine for seedling-raising trays, automatic feeding of trays onto the seedling-raising cart can be achieved, and the feeding operation of trays onto the seedling-raising cart is efficient and orderly. Compared with the traditional working method of manually carrying and placing trays, it effectively replaces manual labor, not only greatly reducing the labor cost but also significantly improving the work efficiency, making the turnover and transportation of trays efficient and orderly, and meeting the usage requirements of intensive seedling raising for the turnover and transportation of trays.

[0089] In one embodiment, asFigures 14 to 16 , Figures 19 to 21 As shown together, the fifth driving device includes a second pushing motor 46 fixedly installed on the mounting frame 41. One end of the mounting frame 41 is rotatably installed with a driving pulley 47. The output shaft of the second pushing motor 46 is in transmission connection with the driving pulley 47. The other end of the mounting frame 41 is rotatably installed with a driven pulley 48 corresponding to the driving pulley 47. A pushing synchronous belt 49 is wound between the driven pulley 48 and the driving pulley 47, and the driven pulley 48 is in transmission connection with the driving pulley 47 through the pushing synchronous belt 49. One end of the pushing frame 44 close to the mounting frame 41 is fixedly connected to one side of the pushing synchronous belt 49.

[0091] In one embodiment, as Figure 14 and Figure 15 As shown together, a third drag chain guide groove is fixedly installed on the lifting platform 28 in the horizontal direction, and a third drag chain is arranged in the third drag chain guide groove. The drag chain can protect and guide the cable, ensuring that the cable can operate stably and safely when the equipment is working.

[0092] In one embodiment, as Figure 14 , Figure 15 , Figure 19 and Figure 22As commonly shown, the sixth driving device includes a second lifting cylinder 53 fixedly installed on the pushing frame 44. The end of the piston rod of the second lifting cylinder 53 is fixedly connected to the second tray pushing plate 54. When the second lifting cylinder 53 operates, it drives the second tray pushing plate 54 to rise or fall. When the second tray pushing plate 54 descends to the pushing position, the second tray pushing plate 54 can abut against one end of the tray 62. When the second tray pushing plate 54 moves, the pushing of the tray 62 is realized. After the second lifting cylinder 53 drives the second tray pushing plate 54 to lift, there is a replenishing gap for the tray 62 to pass between the second tray pushing plate 54 and the lifting platform 28. The next batch of trays 62 can be pushed onto the lifting platform 28 by the first tray pushing mechanism, completing the replenishment of the trays 62 on the lifting platform 28.

[0093] In one embodiment, as Figure 19 and Figure 22 As commonly shown, an anti-warping baffle 55 is fixedly installed on the side of the second tray pushing plate 54 away from the conveyor belt 6. A second strip-shaped mounting hole 5501 is formed in the anti-warping baffle 55. The anti-warping baffle 55 is fixedly installed on the second tray pushing plate 54 by a positioning bolt passing through the second strip-shaped mounting hole 5501. With the provided anti-warping baffle 55, when the second tray pushing plate 54 descends to the pushing position, the anti-warping baffle 55 can press against the end of the tray 62 to prevent the tray 62 from warping when the tray 62 is pushed. In addition, according to the specifications of the tray 62, by loosening the positioning bolt fixing the anti-warping baffle 55, the adjustment of the anti-warping baffle 55 can be realized. After the adjustment is completed, just tighten the positioning bolt again. The adjustment operation is not only simple and convenient, but also can be adaptively adjusted according to different specifications of trays 62, with strong versatility.

[0094] In one embodiment, as Figures 14 to 18 As commonly shown, a flipping and overlapping plate 57 driven by a seventh driving device is provided on the side of the lifting platform 28 away from the conveyor belt 6; to realize the installation of the flipping and overlapping plate 57, a rotating shaft 56 is rotatably installed on the side of the lifting platform 28 away from the conveyor belt 6. The flipping and overlapping plate 57 is fixedly connected to the rotating shaft 56, and the flipping and overlapping plate 57 is rotatably installed on the lifting platform 28 through the rotating shaft 56.

[0095] In one embodiment, as Figures 14 to 18As shown together, the seventh driving device includes a telescopic cylinder 58 hingedly mounted on the lifting platform 28. The telescopic cylinder 58 is located at the end of the lifting platform 28, and the end of the piston rod of the telescopic cylinder 58 is connected to the flipping and overlapping plate 57. When the telescopic cylinder 58 works, it can drive the flipping and overlapping plate 57 to flip. When the piston rod of the telescopic cylinder 58 extends, it drives the flipping and overlapping plate 57 to be overlapped on the seedling-raising cart. After the flipping and overlapping plate 57 is overlapped on the placement table of the seedling-raising cart, the flipping and overlapping plate 57 can cover the gap between the frame 1 and the seedling-raising cart, ensuring that the plug tray 62 can be smoothly pushed onto the seedling-raising cart. After the pushing of the plug tray 62 is completed, the piston rod of the telescopic cylinder 58 retracts, driving the flipping and overlapping plate 57 to reset. After resetting, the flipping and overlapping plate 57 can limit and block the plug tray 62 when the next batch of plug trays 62 are pushed onto the lifting platform 28, preventing the plug tray 62 from slipping off the lifting platform 28.

[0096] In one embodiment, as Figure 17 shown, a hinged connecting plate 59 is installed at the end of the flipping and overlapping plate 57. The end of the piston rod of the telescopic cylinder 58 is hingedly connected to the hinged connecting plate 59, and an avoidance notch 2801 for avoiding the hinged connecting plate 59 is provided on the lifting platform 28, and the avoidance notch 2801 realizes the avoidance of the hinged connecting plate 59.

[0097] In one embodiment, as Figures 1 to 3 、 Figures 14 to 16 shown together, adjusting support feet 60 are installed at the bottom corner positions of the frame 1. The adjusting support feet 60 support the frame 1 and can adjust the height of the frame 1, facilitating the precise docking of each mechanism with the upstream and downstream processes.

[0098] In one embodiment, as Figure 1 shown, a protective net 61 is surrounded on the frame 1. The protective net 61 can protect the equipment inside the frame 1 from external environmental interference and damage, thereby ensuring the normal operation of the equipment and providing a relatively enclosed and safe working environment for the equipment.

[0099] When the multi-layer bed feeding machine for seedling-growing plug trays operates, the first driving device works to drive the conveyor belt 6 to convey the plug trays 62. After the plug trays 62 are conveyed to the discharging end of the transmission frame 2, the limit baffle 13 positions and blocks the plug trays 62. Moreover, after the next conveyed plug tray 62 abuts against the previous one, the previous plug tray 62 positions and blocks the next plug tray 62. In this way, along the conveying direction of the conveyor belt 6 for the plug trays 62, the plug trays 62 can be arranged side by side in sequence. When the number of arranged plug trays 62 reaches the set value, the third driving device works to drive the lifting frame 22 to descend, realizing the descending displacement of the first plug tray pusher 26. Then, the second driving device works to drive the translation frame 14 and the lifting frame 22 to displace in the direction close to the lifting platform 28, and through the first plug tray pusher 26, the multiple side-by-side plug trays 62 are synchronously pushed, and a row of plug trays 62 is pushed onto the lifting platform 28. After that, the third driving device works to drive the lifting frame 22 to rise and reset. At the same time, the second driving device works to drive the translation frame 14 to reset, thus realizing the reset of the first plug tray pusher 26; while the first plug tray pushing mechanism resets, the fourth driving device works to drive the lifting platform 28 to rise or descend to the set height, so that the lifting platform 28 is at the same height as the corresponding empty-layer storage table at present. Then, the seventh driving device works to drive the flipping and overlapping plate 57 to be placed on the current storage table. After that, the sixth driving device works to drive the second plug tray pusher 54 to descend to the pushing position. Finally, the fifth driving device works to drive the pushing frame 44 to displace. Under the guiding action of the plug tray 62 guiding channel, the plug trays 62 on the lifting platform 28 are pushed onto the storage table of the seedling-growing vehicle through the second plug tray pusher 54; after the feeding of the plug trays 62 on one layer of the storage table is completed, the seventh driving device works to drive the flipping and overlapping plate 57 to reset. Then, the fourth driving device works to drive the lifting platform 28 to displace to the initial height position. While the lifting platform 28 resets, the sixth driving device works to drive the second plug tray pusher 54 to rise and reset. The fifth driving device works to drive the pushing frame 44 to reset. When the lifting platform 28 reaches the initial height position, the second plug tray pusher 54 also resets to the replenishing position. At this time, the lifting platform 28 is at the same height as the conveyor belt 6, and there is a replenishing gap for the plug trays 62 to pass between the second plug tray pusher 54 and the lifting platform 28. The next batch of plug trays 62 can be pushed onto the lifting platform 28 through the first plug tray pushing mechanism. Repeat the above steps to push the next batch of plug trays 62 onto the next layer of the storage table of the seedling-growing vehicle, and so on.

[0100] The nursery tray multi-layer feeding machine based on the above structure has a high degree of automation. The conveying of the nursery tray 62 is realized through the tray conveying mechanism. The pushing of the nursery tray 62 at the discharging end of the tray conveying mechanism is realized through the first nursery tray pushing mechanism, and the nursery tray 62 is pushed to the lifting platform 28. The lifting platform 28 driven by the fourth driving device cooperates with the second nursery tray pushing mechanism to push the nursery tray 62 onto the storage racks of each layer of the nursery cart, so as to realize the automatic conveying of the nursery tray 62, the synchronous pushing of multiple nursery trays 62, and the orderly placement of the nursery tray 62 on the storage platforms of each layer of the nursery cart.

[0101] Through this nursery tray multi-layer feeding machine, the automatic feeding of the nursery tray 62 onto the nursery cart can be realized, and the feeding operation of the nursery tray 62 onto the nursery cart is efficient and orderly. Compared with the traditional working method of manually carrying and placing the nursery tray 62, the effective replacement of manual labor is realized. Not only the labor cost is greatly reduced, but also the working efficiency is greatly improved, making the turnover and conveying of the nursery tray 62 efficient and orderly, and meeting the use requirements of intensive nursery for the turnover and transportation of the nursery tray.
