Backpack type semi-automatic fertilization device used in crop growing period

Abstract

The invention discloses a backpack type semi-automatic fertilization device used in the crop growing period. The device comprises a shell. Straps, a power source and a control switch are arranged outside the shell. The shell is of a cylindrical structure. The power source is electrically connected with the control switch. A rotating rod fixedly penetrates through the middle of a first bearing and the middle of a second bearing, the lower end of the rotating rod extends to a closed space formed by a partition plate and the shell, a blocking plate is fixedly installed at the lower end of the rotating rod, communication openings are symmetrically formed in the blocking plate, discharge outlets are symmetrically formed in the lower surface of the bottom end of the shell, and discharge plates are fixedly installed at the lower ends corresponding to the discharge outlets. According to the backpack type semi-automatic fertilization device of the structure, the fertilization condition in the growing process of crops, particularly high crops such as corn crops and cotton crops can be met, the uneven fertilization amount possibly caused by manual fertilization is avoided through the cooperation of an automatic spiral groove and a motor, the physical power burden of workers is relieved, and the working efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of agricultural mechanized equipment, in particular to a backpack-type semi-automatic fertilization device for crop growth. Background technique [0002] In agricultural production, especially in northern China, because most of the farmland is dry land, there are more drought-tolerant crops such as wheat, corn, and sorghum, and there are fewer water-loving crops such as rice. Most of the time is in a state of drought. When you need to add nutrients to the crops in the farmland, you need to fertilize the crops. Nowadays, most of the fertilizer applicators on the market are large-scale and automated. However, in the growing process of crops, many fertilizers must be applied during the growth cycle. The existing machines will destroy the crops and are not convenient for mechanized operations. The intensity is particularly strong when working manually. Summary of the invention [0003] The purpose of the present in...
