Tobacco-seedling ridge-height self-adaptable automatic-guiding transplanter

Abstract

The invention discloses a tobacco-seedling ridge-height self-adaptable automatic-guiding transplanter, which comprises a machine frame, an engine, a seedling throwing frame, a seedling thrower, a planter, a land wheel, a chain wheel box, a self-adaptable induction plate, a front-wheel supporting rod, a front wheel, automatic guide wheels and guide frames. The transplanter disclosed by the invention has an automatic steering function in the working process, manual control is required during turning of the transplanter, therefore the production efficiency is greatly improved; and the guide wheels are provided with protective films and the left and the right sides used for finishing the side surfaces of a ridge wall, which are favorable for the heat and moisture preservation of the films andthe improvement of survival rate of tobacco seedlings. According to the tobacco-seedling ridge-height self-adaptable automatic-guiding transplanter, the changes of ridge height can be automatically induced and a chassis can be automatically adjusted in real time to enable the transplanter to operate in the optimum position, the consistency of the depth of the transplanted tobacco seedlings is guaranteed, and the survival rate of the tobacco seedlings is effectively improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a tobacco seedling ridge height self-adaptive automatic guiding transplanting machine. Background technique [0002] my country is the world's largest producer of tobacco leaves. Tobacco planting basically adopts the technology of floating seedlings in greenhouses and transplanting them to tobacco ridges in tobacco fields. The main problems at present are: [0003] 1. Large-scale tobacco machinery in the United States, Canada, and northern my country adopts a large tractor suspension operating mechanism. The disadvantages are that the turning radius is large, the machine is heavy, and the work efficiency is low. It requires one driver and two staff members to throw seedlings, and the planting depth is unstable. The applicability is not good in the southern smoking area. [0004] 2. The terrain of Japan is similar to the hilly areas in southern my country. Japanese transplan...

AI Technical Summary

Problems solved by technology

[0003] 1. Large-scale tobacco machinery in the United States, Canada, and northern my country adopts a large tractor suspension operating mechanism. The disadvantages are that the turning radius is large, the machine is heavy, and the work efficiency is low. It requires one driver and two staff members to throw seedlings, and the planting depth is unstable. Poor applicability in southern smoking areas

[0004] 2. The terrain of Japan is similar to the hilly areas in southern my country. Japanese transplanting machines have better applicability in southern China, but the price is too expensive and the annual utilization rate of transplanting machines is low. As a result, tobacco transplanting in most parts of the south is mainly done manually. Finish

[0005] 3. The process of manual transplanting of tobacco seedlings is cumbersome, requiring drilling→planting→covering soil→drilling holes near the tobacco seedlings→fertilizing→covering soil→watering, so the workload is very heavy, and the work efficiency of manual transplanting is low, with an average of 0.3 mu / person·day, and with the development of the economy, the value of labor force in rural areas is getting higher and higher, reaching an average of 80 yuan / day·person, so the cost of artificially transplanting tobacco seedlings is very high
