Synchronous fertilization device for fertilizer spreader

Abstract

The invention relates to the technical field of fertilizer applicators, in particular to a synchronous fertilizer application unit of a fertilizer applicator. The synchronous fertilizer application unit comprises a fertilizer discharging and conveying device, a furrowing, fertilization and earthing device, and a fertilization hose; the fertilizer discharging and conveying device and the furrowing,fertilization and earthing device are connected through the fertilization hose to convey a fertilizer; intermittent rotation is achieved for the fertilizer discharging and conveying device since a sheave mechanism common in other industrial fields is applied, so that it is ensured that the time for one fertilizer accumulating cavity, facing down, to release a fertilizer is extended greatly, and it is also ensured that the moist fertilizer can drop more thoroughly under the action of gravity. Each forming unit is in the shape of T having small top and large bottom; air is blown out quickly from a pipeline; after contacting furrow bottom and walls, the fertilizer may contact a T-shaped middle terrace when driven by the air to rotate, and the fertilizer is blocked and returned into one furrow; therefore, concentration of the fertilizer is increased greatly.

Description

technical field [0001] The invention relates to the technical field of fertilizing machines, in particular to a synchronous fertilizing device for fertilizing machines. Background technique [0002] Synchronous side deep fertilization of rice transplanting refers to the fertilization method that concentrates and evenly applies fertilizer to the soil at a certain depth while rice is transplanting. Synchronous fertilization of rice transplanting, the fertilization operation is completed at the same time as rice transplanting, eliminating the need for manual fertilization, greatly reducing labor intensity and saving labor costs. Deep application of fertilizer is also conducive to the absorption of fertilizer during the rice growth period, can promote the growth and development of the root system, can prolong the fertilizer efficiency, improve the utilization rate of fertilizer, and ensure the supply of nutrients during the rice growth period, especially in the late growth perio...

AI Technical Summary

Problems solved by technology

[0003] However, when rice is transplanted, the machine tool is in a hot, high-humidity environment, and the surface of the fertilizer granules is wet and melted, and the fluidity becomes poor.

In addition, if it encounters rainy weather during the fertilization process, the surface of the fertilizer particles will also be wet and the fluidity will be poor.

[0004] After the fluidity is poor, a longer gravity action time is needed to ensure that the wet fertilizer particles are separated from the fertilizer discharge wheel, while the existing fertilizer applicators are doing uniform circular motion, and the fertilizer accumulation groove of the fertilizer discharge wheel is really facing directly downward. The time is very short, the wet fertilizer cannot completely leave the manure tank, and the fertilization effect is poor

[0005] In addition: In our unit's invention patent with the patent number "201820743328.6", "a device for forming ditching and deep fertilization and soil covering for paddy fields" is disclosed. Adjust up and down, the whole force is on the lead screw, and the upper end of the lead screw is fixed on the floating plate of the rice transplanter, the force at the connection of the floating plate is relatively large, and it is very easy to damage

[0006] There is another problem in the actual application process of the above-mentioned patented product: during operation, the fertilizer granules are auxiliary transported in the pipeline by the airflow of the fan.

[0007] Although the above-mentioned patent discloses a soil-covering board, the ordinary soil-covering board has poor soil fluidity when covering soil, especially when used in a paddy field, it cannot better make the soil on both sides of the ditch flow to the position of the fertilizer ditch to fill the mud ditch. Poor covering effect
