Movable sprout cultivation soil-sieving machine

Abstract

The invention discloses a movable sprout cultivation soil-sieving machine. The movable sprout cultivation soil-sieving machine comprises a chassis, the bottom of which is provided with rollers. A bracing frame is fixedly mounted on the rear part of the chassis. A shoveling plate is fixedly mounted at the lower part of the chassis and located below the bracing frame. Breaking teeth are rotatably arranged on the part of the chassis at one side of the shoveling plate through a rotating shaft. The upper and lower ends of the bracing frame are respectively provided with a rotating shaft; a plurality of uniformly distributed delivery tube seats are installed on the bracing frame through chain drive and are fixedly mounted on a chain; the bracing frame is obliquely arranged; a reserve box is fixedly mounted on the part of the chassis at the side to which the bracing frame inclines; and a sieve is fixedly mounted above the reserve box. The movable sprout cultivation soil-sieving machine can be used as corollary equipment for rice cultivation mechanized sprout cultivating equipment, can be driven by a rotocultivator configured on a farm tractor power drive unit and has the advantages of good soil breaking quality, implement function and working performance, operational reliability, stability and reduction in considerable manual labor.

Description

technical field [0001] The invention relates to the field of rice transplanters, in particular to a mobile soil sieving machine for seedling raising. Background technique [0002] At present, a new round of full-coverage technology for mechanized rice transplanting has been rapidly launched in rural areas. In the technical system of mechanized rice transplanting, soil screening is the premise and basis of the entire mechanized seedling raising. The seedlings used in mechanical transplanting are soft and hard disk seedling blocks with nutrient soil as the carrier. 125 kg of fine soil per mu is needed for bed soil and seed cover soil, which requires a large amount of soil and high quality requirements. However, the crushing and screening of mechanized seedling soil sieving machine is labor-intensive and labor-intensive, so mechanical sieving must be promoted. Contents of the invention [0003] The invention provides a movable mechanized soil sieving machine, which greatl...
