Description

Technical Field

[0001] The invention relates to the technical field of planting machines, in particular to a rice seedling planting machine with a fertilization function. Background Art

[0002] Due to geographical location factors, rice is the main food crop in my country. During the rice planting process, rice seedlings need to be inserted into the ground. With the development of technology, planting machines can be used for transplanting, which greatly improves planting efficiency.

[0003] In the prior art, a rice transplanter with the authorization publication number CN111448879B includes a rice seedling group storage device, a rice seedling group feeding device, a rice seedling sorting device and a rice seedling planting device. The rice seedling group storage device is used to place a rice seedling mesh plate containing rice seedling pots. The rice seedling group feeding device is used to transfer the rice seedling mesh plate placed on the rice seedling group storage device to the rice seedling sorting device. The rice seedling sorting device is used to take out the rice seedling pots contained on the rice seedling mesh plate transferred by the rice seedling group feeding device and sort the taken out rice seedling pots. The rice seedling planting device is used to insert the rice seedling pots sorted by the rice seedling sorting device into the land, thereby improving the automation of rice seedling planting, improving production efficiency and saving labor costs.

[0004] In the actual implementation process of the above device, the rice seedlings will be stored in the rice seedling group storage device, which is easily affected by the ambient temperature and becomes dry. However, the device is inconvenient to water the rice seedlings to keep them active. In addition, it is inconvenient to fertilize the land during the planting process, and the practicality is low. For example, in a rice fixed-point quantitative deep fertilization device with the authorization publication number CN103931318B, it includes transplanting, a frame assembly, a fertilizer assembly mounting frame and an air gun fertilizer assembly. The frame assembly is provided with a fertilizer assembly mounting frame, and the fertilizer assembly mounting frame is provided with an air gun fertilizer assembly, which uses the air gun principle to directly inject large granular urea into the mud near the seedlings;

[0005] In the actual operation of the above-mentioned device, it is inconvenient to apply fertilizer during dry load, that is, the air gun type fertilizer assembly in the above-mentioned device is not suitable for a rice transplanter with publication number CN111448879B. When the fertilizer pipe is directly inserted into the land, the soil is easy to adhere to the inside and outside of the fertilizer pipe, causing the fertilizer pipe to be blocked, affecting the subsequent fertilization operation.

[0006] Therefore, we propose a rice seedling planting machine with fertilization function to solve the above-mentioned problems. Summary of the invention
