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] At present, the placement of the plug trays on the seedling raising vehicle is mainly done manually. The operating workers need to manually carry the plug trays and place the plug trays on the seedling raising vehicle in sequence. Since the seedling raising vehicle is a multi-layer structure with several layers of storage tables, multiple plug trays can be placed side by side on each storage table in sequence. Therefore, when loading the plug trays on the seedling raising vehicle, the plug trays need to be placed one by one on the storage table manually. After one layer of storage table is filled, the next layer of storage table can be placed. However, the working method of manually carrying and placing the plug trays on the seedling raising vehicle is not only labor-intensive, time-consuming and labor-intensive, but also has high labor costs and low work efficiency. In addition, when placing the plug trays on the top few storage tables of the seedling raising vehicle, due to the high height of the storage table and the mobility of the seedling raising vehicle itself, it is difficult to place the plug trays, the operation is extremely inconvenient, and there are certain safety hazards.

[0057] In one embodiment, if Figures 14 to 18As shown in common, 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 piston shaft end of the telescopic cylinder 58 is connected to the flip lap plate 57. When the telescopic cylinder 58 works, it can drive the flip lap plate 57 to flip. When the piston shaft of the telescopic cylinder 58 extends, the flip lap plate 57 is driven to overlap the seedling car. When the flip lap plate 57 is overlapped on the storage table of the seedling car, the flip lap plate 57 can cover the gap between the frame 1 and the seedling car, ensuring that the hole tray 62 can be smoothly pushed to the seedling car. After the hole tray 62 is pushed, the piston shaft of the telescopic cylinder 58 retracts, driving the flip lap plate 57 to reset.

[0061] When the multi-layer seedling tray bed machine is running, the first driving device works to drive the conveyor belt 6 to transport the tray 62. After the tray 62 is transported to the unloading end of the transmission frame 2, the limit baffle 13 realizes the positioning and blocking of the tray 62. After the next tray 62 is transported against the previous tray 62, the previous tray 62 realizes the positioning and blocking of the next tray 62. In this way, the trays 62 can be arranged side by side in sequence along the conveying direction of the trays 62 of the conveyor belt 6. When the number of arranged trays 62 reaches the set value, the third driving device works to drive the lifting frame 22 to descend, so as to realize the descending displacement of the first tray push plate 26. Then, the second driving device works to drive the translation frame 14 and the lifting frame 22 to move in the direction close to the lifting platform 28, and the first hole tray push plate 26 is used to synchronously push the multiple hole trays 62 arranged side by side, and a row of hole 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, thereby realizing the reset of the first hole tray push plate 26. While the first hole tray pushing mechanism is reset, the fourth driving device works to drive the lifting platform 28 to rise or descend to a set height, so that the lifting platform 28 and the corresponding space at the current location are aligned. The storage platforms of the first and second layers are at the same height, and then the seventh driving device works to drive the flip lap plate 57 to be placed on the current storage platform, and then the sixth driving device works to drive the second plug tray push plate 54 to descend to the pushing position, and finally, the fifth driving device works to drive the pushing frame 44 to move, and under the guidance of the plug tray 62 guide channel, the plug tray 62 on the lifting platform 28 is pushed to the storage platform of the seedling raising vehicle through the second plug tray push plate 54; after completing the loading of the plug tray 62 on one layer of the storage platform, the seventh driving device works to drive the flip lap plate 57 to reset, and then the fourth driving device works to drive the lifting platform 28 to move to the initial height position When the lifting platform 28 is reset, the sixth drive device works to drive the second plug tray push plate 54 to rise and reset. The fifth drive device works to drive the pushing frame 44 to reset. When the lifting platform 28 reaches the initial height position, the second plug tray push plate 54 is also reset to the feeding position. At this time, the lifting platform 28 and the conveyor belt 6 are at the same height, and there is a feeding gap between the second plug tray push plate 54 and the lifting platform 28 for the plug tray 62 to pass through. 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 to the next storage platform of the seedling raising vehicle, and repeat this process.

[0062] The multi-layer seedling tray loading machine based on the above structure has a high degree of automation. The transportation of the hole tray 62 is achieved through the hole tray conveying mechanism, and the pushing of the unloading end hole tray 62 transported to the hole tray conveying mechanism is achieved through the first hole tray pushing mechanism. The hole tray 62 is pushed to the lifting platform 28, and the lifting platform 28 driven by the fourth driving device cooperates with the second hole tray pushing mechanism to push the hole tray 62 to each layer of the storage rack of the seedling vehicle, thereby realizing the automatic transportation of the hole tray 62, the synchronous pushing of multiple hole trays 62 and the orderly placement of the hole trays 62 on each layer of the storage table of the seedling vehicle.

[0063] Through the multi-layer seedling tray loading machine, the plug tray 62 can be automatically loaded onto the seedling vehicle, and the loading operation of the plug tray 62 on the seedling vehicle is efficient and orderly. Compared with the traditional working method of manually carrying and placing the plug tray 62, it realizes the effective replacement of manual labor, not only greatly reduces the labor cost, but also greatly improves the work efficiency, makes the turnover and transportation of the plug tray 62 efficient and orderly, and meets the use requirements of intensive seedling cultivation for the turnover and transportation of the plug tray.
