This research aims at the problem of sticky lump soil in the southern region, and the problem that vegetables are not easy to be transplanted mechanically, 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 machine is composed of seedling box frame, turntable mechanism, duckbill mechanism and suppression device. The pot seedlings are manually taken out from the seedling box frame, and the pot seedlings are put into the seedling cup of the turntable mechanism in a clockwise direction, and the turntable mechanism It is powered by a gasoline engine and is converted by a gearbox to reach the corresponding speed. When the seedling cup and the duckbill mechanism reach zero at the same time, the lower end of the seedling cup is opened, and the bowl seedling falls into the duckbill mechanism, and the duckbill mechanism is on the crank and rocker. Under the trajectory of movement, vertical penetration into the soil is realized. When the duckbill reaches the lowest point, the duckbill mechanism opens the duckbill and the pot seedling falls into the soil. The duckbill mechanism moves upwards driven by the crank and rocker mechanism. In the open state, when the pot seedling is separated from the duck beak, the duck beak is closed and returned to the zero point, and finally the pressing wheel compacts the transplanted pot seedling to realize the vegetable transplanting process. The disc knife device cuts or presses the debris and large soil blocks at the front end of the planter planting seedlings to the bottom of the soil; while the seedlings are transplanted, drip irrigation belts are laid at the same time, and water and fertilizer integration devices are connected, which can take care of both Water for two rows of vegetables.The test results show that: the diameter of the broken soil particles of the prototype is 0.4cm, the sticky soil of the inserting device is 3.5g, the planting depth is 2.8cm, the transplanting qualification rate is 91.2%, no missing 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. It realizes the integration of agricultural machinery and agronomy, solves the problems of high labor intensity and low production efficiency of farmers, and provides technical support for vegetable transplanting in the southern region. Its social and economic benefits Significantly.
