Description

Technical Field

[0001] The present application relates to the technical field of farmland fertilization, and more specifically, to a farmland fertilization device. Background Art

[0002] Chemical fertilizers are referred to as fertilizers. Fertilizers made by chemical and (or) physical methods contain one or more nutrients required for the growth of crops. my country is a large agricultural country with a large number of vegetable growers. In the process of vegetable planting, it is necessary to fertilize the vegetable planting pits to ensure the growth of vegetables. Therefore, growers usually use fertilizer spreading devices to fertilize vegetables.

[0003] According to the search, a Chinese patent with patent announcement number CN213718692U discloses a fertilizer spreading device, including a base, a fixture is fixedly installed at the bottom of the base, a roller is rotatably connected to the inner side of the fixture, a connecting rod is fixedly installed at the left side of the base, a push handle is fixedly installed at the top of the connecting rod, a box is fixedly installed at the top of the base, a feed hopper is fixedly installed at the top of the box, a protective box is fixedly installed at the front of the box, a heat dissipation hole is opened at the front of the protective box, and a discharge hopper is fixedly installed at the bottom of the box. The rollers set in this fertilizer spreading device can make the device move by itself, and there is no need to move the fertilizer by manpower for spreading, which reduces the inconvenience of fertilizing the land during crop planting. The uniform leaker can adjust the speed of fertilizer leakage, which is more suitable for fertilization.

[0004] With respect to the above-mentioned related technologies, the applicant believes that although the above-mentioned spreading device can be used to spread fertilizers when in use, when planting vegetables, usually in the farmland, holes are dug longitudinally and at equal intervals, and the vegetable seedlings are planted in the holes. Since the above-mentioned device applies fertilizers continuously and the fertilization surface is wide, it is not convenient to automatically and fixedly fertilize each planting hole, and the fertilization effect is poor. At the same time, it is easy to cause fertilizer waste. For this reason, we propose a farmland fertilization device. Utility Model Content
