Raw material feeding device for rice seedling raising

Abstract

The invention relates to the technical field of rice seedling raising, in particular to a raw material feeding device for rice seedling raising. The device comprises a mounting plate, enclosure pipesare arranged on the bottom surface of the mounting plate, a motor is arranged on the top surface of the mounting plate, a rotor of the motor is in transmission connection with a screw shaft through acoupler, an extension pipe sleeves the outer side of each enclosure pipe, a soil breaking blade is arranged on the outer wall of the extension pipe, a baffle ring sleeves the outer side of each enclosure pipe, a connecting frame is arranged on the top surface of the mounting plate, a material box is arranged on the top surface of the connecting frame, a feeding opening is formed in a bottom plateof the material box, and a material conveying pipe is inserted into the bottom end of the feeding opening. The device has the beneficial effects that: multiple sets of enclosure pipes are installed below the mounting plate, the screw shaft is additionally arranged in each enclosure pipe to convey a fertilizer fed by the material conveying pipe into soil, the extending length of the extension pipearranged on the outer side of each enclosure pipes in a sleeving mode can be adjusted, and soil with different depths can be fertilized conveniently.

Description

technical field [0001] The invention relates to the technical field of rice seedling raising, in particular to a raw material feeding device for rice seedling raising. Background technique [0002] Paddy dry seedling raising technology, the main advantage of this seedling raising method is that the seedling age is short, the seedlings are strong, and the management is convenient. It can be inserted by machine or by hand, with high efficiency and good quality. The seedlings can be intensified and the production is specialized. Save species, save water, and have high economic benefits. Suitable for different production systems. [0003] In the prior art, the bed soil of rice dry seedling raising technology is soft. In order to improve the fertility of the soil, granular chemical fertilizers are usually spread on the soil surface, but it is difficult for the chemical fertilizers on the soil surface to supplement the fertility of the lower soil, resulting in uneven soil ferti...
