Hand-held rice transplanter with automatic moisturizing of seedling blocks

Abstract

A walking type rice transplanter with a function of automatic seedling moisturizing comprises a frame, a seedling supply mechanism, a seedling transplanting mechanism, walking wheels, handles and a float plate. The seedling supply mechanism, the seedling transplanting mechanism, the walking wheels, the handles and the float plate are arranged on the frame. A quantitative spraying mechanism is arranged on the upper front side of a seedling tray which is arranged on the seedling supply mechanism. The quantitative spraying mechanism comprises a spraying pipeline and a liquid storage tank, the spraying pipeline facing the seedling tray is provided with a plurality of abreast spraying holes axially along the pipeline, the spraying holes are distributed sequentially from one end of the spraying pipeline to the other end of the spraying pipeline, nozzles are arranged at the spraying holes, and a liquid inlet pipe is arranged in the middle of the spraying pipeline. A quantitative barrel for measuring spraying amount is arranged below the liquid storage tank, a float valve is arranged at a liquid inlet of the quantitative barrel, a water pump is arranged at a liquid outlet of the quantitative barrel, and the liquid inlet pipe of the spraying pipeline is connected with the water pump. A humidity detection mechanism for detecting water content of seedlings is arranged on a seedling delivery belt, and a control mechanism for controlling the float valve and the water pump is arranged on the frame. By the humidity detection mechanism, real-time humidity monitoring of the seedlings is realized. By the quantitative spraying mechanism, automatic seedling moisturizing is realized.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a walk-behind rice transplanter with automatic moisturizing of seedling blocks. Background technique [0002] As one of the grain crops with the largest planting area and the highest yield in my country, rice plays a decisive role in the economic development of our country and the improvement of farmers' living standards. With the increase of my country's population, the planting area of ​​rice will increase in the future. Japan is one of the countries with a high level of rice mechanization development in the world. It achieved a high degree of mechanization in agricultural production in the 1980s, and the level of agricultural mechanization development is at the forefront of the world. [0003] There are currently two ways to mechanize rice transplanting: one is raising seedlings in the field, pulling out seedlings, and then transplanting them with a transplanter; . There is an exi...

AI Technical Summary

Problems solved by technology

[0004] The existing hand-held rice transplanter with automatic moisturizing of seedling blocks will put the seedling blocks into the seedling box before transplanting. When the seedling blocks are too dry, they can be properly sprinkled with water to make them moist, which not only facilitates the easy sliding of the seedling blocks, but also It can ensure the moisture content of the seedlings, otherwise, the seedlings will not meet the requirements of machine transplanting, which will reduce the quality of work

In the prior art, the watering of the hand-held rice transplanter with automatic moisturizing of the seedling block is mainly sprayed directly by the user, and the grasp of the spraying amount must rely on experience, the degree of automation is low, the requirements for the user are high, and the applicability is narrow.
