Screening method of rice field seedling-raising mud

Abstract

The invention discloses a screening method of rice field seedling-raising mud. Screening is carried out by adopting a rice field seedling-raising mud screening machine. Soil blocks firstly enter intoa crushing area in a mud stirring conveying device through a feed hopper of the rice field seedling-raising mud screening machine; a first stirring shaft and a second stirring shaft rotate to drive soil crushing rods to crush the soil blocks and stir the crushed soil blocks for forming small granules; the small granules are driven by a conveying spiral to enter a spiral propulsion area; the smallgranules are mixed with water to form mud; the mud flows into a vibrating screen body through a stirring discharge guide plate; after the mud is shaken up and down by a vibrating transverse groove body and a vibrating sieving body, mud with a particle diameter smaller than the diameter of vibrating sieving hole falls into a mud collecting box, so that the mud required for the seedling raising is obtained; and impurities and the like remaining on the vibrating sieving body gradually moves forward along with the moving of the vibrating sieving body, and falls into an impurity collecting box. Thescreening effect is remarkable, the labor intensity is effectively reduced, and the productivity is improved.

Description

technical field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a method for screening mud for seedling raising in rice fields. Background technique

[0002] my country is the country with the largest rice production in the world, and rice is the main food crop in my country. There are two methods of rice planting in my country, direct seeding and transplanting, among which transplanting is the main planting method, and in the transplanting method, the most important link is seedling raising. There are mainly two kinds of mechanized seedling raising methods in my country, one is industrial seedling raising, and the other is field seedling raising, wherein field seedling raising is the main method used in southern my country.

[0003] Seedling raising technology in the field includes plate placement, mud laying, precision sowing, and seed pressing. The process of plate placement and seed pressing is simple, the labor intensity ...
