Soil base material refining device for rice culture

Abstract

The invention discloses a soil base material refining device for rice culture. The soil base material refining device comprises a tank body, a feeding port and a discharging port, wherein the feedingport is formed in the top end of the tank body; a smashing device is arranged at the feeding port; the discharging port is formed in the lower end of the right side of the tank body; a first motor isarranged on the right side of the tank body and connected with a first drive rotating shaft; and a plurality of smashing paddles are fixedly connected onto the first drive rotating shaft. When the soil base material refining device for the rice culture is used, the first motor is started to drive the first drive rotating shaft and the first smashing paddles to rotate, soil is cut and smashed in the vertical direction, the treated soil penetrates through a first sieving plate and falls on a second sieving plate, sliding sleeves at the two ends of the first sieving plate slide along slide rods,supporting springs provide elastic force, when too much soil is accumulated, the first sieving plate moves downwards, smashing space of the first smashing paddles is increased, the first sieving plateshakes , so that accumulation of the soil on the first sieving plate is reduced, and the blockage is prevented.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a soil base material thinning device for rice cultivation. Background technique [0002] The soil used for agricultural planting is easy to agglomerate after a long time, which reduces the air permeability of the roots. As if the roots are sealed up, the agglomerated soil needs to be crushed, which increases the gaps between the soil particles. The air is easy to enter, which increases the respiration of root cells, and the respiration is strengthened, which can strengthen transpiration and promote the exchange of mineral elements in the root hairs and soil, which can also promote the absorption of mineral elements by the roots; especially in the process of seedling cultivation Among them, the requirements for the soil are higher, and the requirements for the degree of refinement of the soil are more stringent, so that the soil can be fully mixed with other nutrien...

AI Technical Summary

Problems solved by technology

[0003] Due to the single crushing structure of the existing soil crushing equipment, the crushing quality is unstable, and the size of the crushed soil particles is different, which is likely to cause uneven mixing and agglomeration of the components of the cultivated soil, chemical fertilizers and soil, and affect the quality of the cultivated soil and fertilizer effect
