An agricultural mechanized fertilization device

Abstract

The invention provides an agricultural mechanized fertilization device, comprising: a frame; a material storage box; a rotating part, which is rotatably mounted on the side wall of the material storage box; The device drives the rotating part to rotate; the discharge part is connected to the storage box and has a side facing the rotating part, and the bottom of the discharge part is provided with a discharge hole; the discharge pipe is connected to the rotation part, and the two ends of the discharge pipe There are first and second nozzles, the first nozzle communicates with the concave cavity, and there is an alignment station where the second nozzle is aligned with the discharge hole during the rotation stroke of the discharge pipe, and the second nozzle is in close contact with the side of the discharge member. With the rotation of the rotating part, the discharge pipe is intermittently in the alignment position; when it is in the alignment position, the first nozzle is higher than the second nozzle, and the fertilizer in the concave cavity passes through the discharge pipe by gravity. The feed tube slides into the discharge hole and exits. Beneficial effects: With the help of gravity discharge, the method is simpler, the fertilizer is easier to discharge, and it is easy to control and achieve the required fertilization effect.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an agricultural mechanized fertilization device. Background technique [0002] In the process of agricultural production, such as corn, sunflower, etc., when the initial seedlings are low, tractors can be used to fertilize. When the seedlings grow and develop, tractors can no longer fertilize, and only manual fertilization or manual fertilization devices can be used. The labor intensity is high, the work efficiency is low, and the fertilizer is easy to agglomerate, which cannot meet the needs of agricultural production. [0003] In this regard, the Chinese invention patent application with the application publication number CN110122012A discloses an adjustable fertilization device for corn planting, which includes a frame, a fertilizer cylinder and a fertilizer feeding mechanism. The mechanism includes a fertilizer feeding pipe, a fertilizer feeding tray and a dri...

Problems solved by technology

[0005] Although the above-mentioned fertilization device can realize intermittent fertilization, the reason why the fertilizer can be discharged from the fertilizer cylinder is entirely due to the centrifugal force generated when the fertilizer delivery disc rotates. Therefore, the requirement for the rotation speed of the fertilizer delivery disc is relatively high. It is difficult to discharge, and it is necessary to accurately adjust the rotation speed of the fertilizer feeding tray, and the fertilizer feeding tray and the stirring shaft rotate synchronously, and the rotating speed of the fertilizer feeding tray and the stirring shaft will affect the mixing effect and quality of the fertilizer, that is, the rotation speed of the fertilizer feeding tray The setting also needs to consider the stirring of the fertilizer, so it is very difficult to reasonably set the speed of the fertilizer feeding pan

At the same time, even if the rotation speed of the fertilizer feeding plate is appropriate, most of the fertilizer cannot be discharged due to the influence of the U-shaped trough structure, but as the U-shaped trough continues to rotate, the discharged fertilizer is limited, and it is difficult to achieve ideal fertilization.
