Transplanting planting distance adjusting device for transplanting machine

Abstract

A transplanting planting distance adjusting device for a transplanting machine comprises a chain wheel mechanism I and a chain wheel mechanism II, wherein a set of corresponding chain wheels on the chain wheel mechanism I and the chain wheel mechanism II are sleeved with a closed-loop chain, the chain is provided with an automatic tensioning mechanism, a tensioning wheel rotates around a tensioning wheel axle through the torsional moment effect of a tensioning spring to automatically realize the tensioning of the chain, a wheel changing mechanism I used for adjusting the position of the chain on the chain wheel mechanism I is arranged on one side of the chain wheel mechanism I, and a wheel changing mechanism II used for adjusting the position of the chain on the chain wheel mechanism II is arranged on one side of the chain wheel mechanism II. The transplanting planting distance adjusting device simplifies the planting distance adjustment operation and saves the adjustment time, when the transplanting planting distance of the transplanting machine needs to be changed, a driving land wheel does not need to be disassembled and assembled, the relative position of the chain wheel also does not need to be replaced or adjusted, and the disassembling and assembling cumbersome processes in the process of adjusting the transplanting planting distance are eliminated, so that time and effort are saved, and the using effect is better.

Description

technical field [0001] The invention relates to equipment for transplanting crops, in particular to a plant-to-plant spacing adjustment device for a transplanter. Background technique [0002] Along with the development of agronomy, the planting of commercial crops such as cotton and tobacco begins to use potted seedling transplanting technology. The traditional transplanting of crops is manual transplanting, which is gradually being replaced by mechanical transplanting; different pot seedlings are transplanted, and the transplanting spacing is different. For the transplanting machine, the transplanting spacing is the same as the driving ground wheel Transmission ratio to transplanting mechanism There is a positive correlation, the transmission ratio The change of the transplanting distance will produce the change of the transplanting distance; however, the machine cannot change the transplanting distance intelligently like a human being when transplanting. The device i...

Problems solved by technology

However, the power source of the traction transplanter on the market is the ground wheel, and the ground wheel transmits the power to the gearbox or directly to the transplanting and seedling throwing mechanism through the chain drive, and the transmission ratio of the chain drive behind the ground wheel is changed. Change the plant spacing of different transplanting machines; however, the current method of changing the transmission ratio is relatively complicated. After removing the ground wheel and replacing it with a sprocket with a different transmission ratio, and then installing the relevant components to complete the adjustment of the plant spacing of transplanting, the whole process is cumbersome. Time-consuming
