Hanging bucket type semi-automatic crop transplanting machine

Abstract

The invention discloses a hanging bucket type semi-automatic crop transplanting machine which comprises a walking driving wheel (1); a walking wheel (6) is connected to a stand (8) by a bearing seat (12); a seedling dropping mechanism (2), a pull-down plate (4), an adjusting screw rod (5) and a compacting mechanism (9) are fixedly arranged on the stand (8); a pull-up plate (3) is connected to the pull-down plate (4) and is connected with an upper pull rod and a lower pull rod of a tractor, so that drawing and lifting of the machine can be realized; a seedling planting mechanism (10) is connected with the adjusting screw rod (5) and is fixed to the stand (8); a hydraulic motor (7) is fixed to the seedling planting mechanism (10) so as to provide seedling transplanting force and reduce the advance resistance of the walking driving wheel (1); and an adjustable plant spacing variable speed drive mechanism (11) is connected with the walking driving wheel (1) and the seedling planting mechanism (10), so that stepless speed change between the walking driving wheel (1) and the seedling planting mechanism (10) can be realized. The machine can realize semi-automatic crop seedling transplanting operation with stepless regulation for plant spacing and row spacing.

Description

technical field [0001] The invention relates to the transplanting operation of various crop seedlings in the field. Background technique [0002] Transplanting is a common method of crop production. Firstly, young seedlings are cultivated in the seedbed, and then transplanted to the field after the seedlings are strong. The transplanting method can realize the separate planting of large and small seedlings, and the seedlings can maintain a reasonable row and plant spacing, which is beneficial to field agronomic management. Inconsistent density and inconsistent growth rate will affect the yield. However, if the manual method is used for transplanting, it is labor-intensive, time-consuming, and increases costs, especially in large-scale planting, which requires mechanized operations. [0003] At present in my country, rice transplanting has achieved a high level of mechanization through years of hard work. However, the transplanting of crops such as tobacco, rapeseed, potat...

AI Technical Summary

Problems solved by technology

Rice transplanting is an agronomic technique for transplanting multiple plants in paddy fields, and rice transplanters cannot meet the agronomic requirements for transplanting single crops in dry land

In recent years, mechanical transplanting has begun to be used in the transplanting of rapeseed and tobacco, but the transplanting models are still in the promotion stage, and there are still many technical problems that need to be solved

Especially in my country, which has a vast territory, different types of crops or different regions have different requirements for row spacing and plant spacing, and their values ​​vary greatly. Improper control of this important agronomic parameter will affect crops. Now there are several types There are still some problems in the adaptability of the transplanting machine, especially the adjustment of the plant distance, which is troublesome to operate by changing the number of sprocket teeth, and it is difficult to achieve the ideal size of the plant distance

China's agricultural machinery market has not really matured crop seedling transplanting machinery
