Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer application devices, in particular to a fertilizer application machine for crop planting. Background Art

[0002] In order to meet the nutrient needs of crops in different growth cycles, it is usually necessary to manage crops by fertilization. Organic fertilizers contain more comprehensive nutrients, but the fertility of organic fertilizers evaporates slowly. Applying fertilizers directly to the soil surface and exposing them to the air can easily weaken the fertility and reduce the utilization rate of fertilizers. Therefore, deep fertilization is usually used, that is, before fertilization, it is necessary to dig a fertilization pit, and then fill the fertilization pit after fertilization. In addition, digging fertilization pits, fertilizing and filling require workers to change different tools to operate, which leads to cumbersome fertilization management and low fertilization efficiency.

[0003] In order to improve the efficiency of fertilization, a patent application with authorization announcement number CN218868688U discloses a fertilizer spreader. Through the cooperation of components such as a brick rod and a discharge nozzle, when the fertilizer spreader is in use, it can automatically drill holes and then apply fertilizer under the soil, thereby achieving deep fertilization and improving the fertilization effect.

[0004] However, since the fertilizer spreader sprays by mixing fertilizer and water, some substances in the fertilizer dissolve in the water after the fertilizer and water are mixed, resulting in a higher viscosity of the fertilizer-water mixture. The fertilizer-water mixture easily adheres to the discharge nozzle and affects the fertilization effect. When the mixture adhered to the discharge nozzle accumulates to a certain extent, it may even cause the nozzle to be blocked.

[0005] Therefore, there is an urgent need for a crop planting fertilizer applicator that can deeply apply fertilizer and is convenient for fertilizer management. Summary of the invention

[0006] The purpose of the present invention is to solve at least the above-mentioned drawbacks and provide advantages which will be described later.

During the movement of the fertilizer spreader for crop planting, the rake hook passes through the fertilizer and soil in the fertilization pit. The rake hook further hooks up the soil at the bottom of the fertilization pit and at the same time brings the fertilizer into deeper soil, thereby increasing the fertilization depth.

[0021] Preferably, the groove portion, the soil covering portion and the discharge port are each provided with two, and are symmetrically arranged on the left and right sides of the machine body.
