This research aims at the problem o

This research aims at the problem of sticky lump soil in our province and southern regions, and the problem that vegetables are not easy to be mechanically transplanted, and researches on mechanized transplanting equipment and supporting technologies suitable for vegetables. Through optimizing the design, a vegetable transplanter suitable for southern regions was designed, and demonstration and promotion were carried out at the same time. The transplanter consists of a seedling box frame, a turntable mechanism, a duckbill mechanism and a suppression device. The pot seedlings are manually taken out of the seedling box frame, and the pot seedlings are placed in the clockwise direction (from top to bottom) in turn. The seedling cup of the turntable mechanism. The turntable mechanism is powered by the engine and converted by the gearbox to reach the corresponding speed. When the seedling cup and the duckbill mechanism reach the zero point at the same time, the lower cover of the seedling cup opens and the bowl seedling falls into the duckbill mechanism , The duckbill mechanism realizes vertical penetration into the soil under the trajectory of the crank and rocker movement. When the duckbill reaches the lowest point, the duckbill mechanism opens the duckbill and the seedling falls into the soil. The duckbill mechanism is driven by the crank and rocker mechanism. , Move up, the duck beak is open, when the bowl seedling is separated from the duck beak, the duck beak closes and returns to the zero point, and finally the pressing wheel compacts the transplanted bowl seedling to realize the vegetable transplanting process. Improve the design of the disc cutter device, cut the debris, large soil blocks, etc. on this line of the planter planting seedlings or press them under the soil layer; design a drip irrigation belt laying device, and the drip irrigation will be laid at the same time as the seedlings are transplanted. Belt: A drip irrigation belt is connected with a water and fertilizer integration device, which can take care of the water for two rows of vegetables at the same time.The test results show that: the diameter of the broken soil particles of the prototype is 0.4cm, the sticky soil of the transplanter is 3.5g, the planting depth is 2.8cm, the transplanting pass rate is 91.2%, no missed planting or replanting, and the lodging rate is 6.3% , The productivity is 4200 plants/h. This machine is suitable for the mechanized transplanting of vegetables in the southern region, and realizes the integration of agricultural machinery and agronomy. Its social and economic benefits are significant. It solves the problems of high labor intensity and low production efficiency of farmers and provides technology for vegetable transplanting in the south support.
