Description

Technical Field

[0001] The present invention relates to the technical field of tobacco planting equipment, and in particular to a tobacco planting device and method. Background Art

[0002] Traditional planting methods have many inconveniences and inefficiencies. For example, the planting process requires multiple steps such as pond digging, watering, fertilizing, and ridge making. These operations often need to be completed manually, which is not only labor-intensive but also inefficient. In addition, traditional planting equipment often has a single function and cannot complete multiple steps at the same time, making the planting process cumbersome and time-consuming.

[0003] After searching, a seedling planting and fertilizing integrated machine with publication number CN110637574A is found, which relates to the field of mechanized tobacco planting. The seedling planting and fertilizing integrated machine includes a seedling planting tube, a handle assembly, a linkage assembly, a soil breaking assembly, a metering assembly and a fertilizing assembly, wherein the handle assembly and the soil breaking assembly are both connected to the seedling planting tube, and the handle assembly is arranged at one end of the seedling planting tube, the soil breaking assembly is arranged at the other end of the seedling planting tube, the metering assembly is connected to the fertilizing assembly, and both are connected to the seedling planting tube, the dosage assembly is arranged between the handle assembly and the soil breaking assembly, the fertilizing assembly is arranged at one end of the seedling planting tube close to the soil breaking assembly, and the linkage assembly controls the soil breaking assembly and the fertilizing assembly.

[0004] The integrated seedling planting and fertilizing machine provided by the above invention can simultaneously realize the transplanting and fertilizing of tobacco seedlings, but it cannot deal with the situation where the seedlings are stuck when transplanting the seedlings. When planting seedlings in the seedling planting tube, it is necessary to manually insert the soil-breaking component and the fertilizing component into the soil with force, turn the metering wrench, let the opening of the metering part connect with the feed port in the metering cylinder, so that the fertilizer enters the metering cavity, put down the metering wrench, and rotate the opening of the metering part to connect with the discharge port in the metering cylinder, so that the fertilizer enters the fertilization cavity through the discharge port.
