Furrowing, fertilization and earthing device of rice transplanting synchronous fertilizer applicator

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a furrowing, fertilization and earthing device of a rice transplanting synchronous fertilizer applicator. The furrowing, fertilization and earthing device comprises a furrower, a fertilization tube holder, and a fertilization tube connector; the fertilization tube connector is fixed to the upper portion of thefertilization tube holder. The furrowing, fertilization and earthing device also comprises an electric push bar, a first pin, a support arm, a second pin and a former; the top of the electric push bar is used for being hinged to a frame of a rice transplanter; the bottom of the electric push bar is hinged to the top of the furrower through the first pin; the bottom of the furrower is hinged to the bottom of the support arm through the second pin; the top of the support arm is used for being fixedly welded to a cross beam of the rice transplanter; the bottom of the furrower is lower than the bottom surface of a floating plate of the rice transplanter; the fertilization tube holder is welded to the rear of the support arm; the former is welded to the bottom of the fertilization tube holder;the former is in the shape of T having small top and large bottom; concentration of a fertilizer is increased greatly; an earthing unit plate in wavy shape provides better earthing effect; furrowingdepth is convenient to adjust.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a ditch fertilization and soil covering device for a synchronous fertilizer applicator for rice transplanting. 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 r...

Problems solved by technology

[0004] In the utility model patent of our unit with the patent number "201820743328.6", "a device for forming ditching and deep fertilization and covering soil for paddy fields" is disclosed. Adjustment, the entire 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

[0005] 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.

[0006] In addition, 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. Buried, poor effect of covering soil
