Hand-held rice seedling machine

Abstract

The invention relates to a hand-held rice seedling machine, which comprises a pull bar, a plough portion, a seeder and a seed covering device, wherein the seeder is composed of a stand frame, a funnel groove, a rotating shaft, and traveling wheels. Two ends of the rotating shaft are provided with two traveling wheels respectively; the stand frame bears on the rotating shaft; the funnel groove is movably arranged in the stand frame and slide leftwards and rightwards in the axial direction of the rotating shaft; the bottom of the funnel groove is provided with a plurality of leak holes; the rotating shaft is provided with a plurality of gears; wheel rims of the gears are provided with a plurality of gear grooves which correspond to the leak holes; the plough portion is composed of a plurality of small ploughs which are movably connected to the front end of the stand frame by the pull bar; and the seed covering device is composed of a soil covering plate which is connected with the front end of the stand frame by a plurality of propeller struts. The invention applies a unitized structure which integrates the plough portion, the seeder and the seed covering device together to complete grooving, sowing, and covering soil in a pulling. The invention possesses an integrated simple structure, convenient operation, high practicality, broad application, and uniform density and proper depth in sowing, and is good for regular sprouting of rice to guarantee harvest.

Description

technical field [0001] The invention relates to a rice seeder, in particular to a hand-held rice seeder. Background technique [0002] Traditional rice sowing farmers will use tractors to bury the grass, return the straw to the field, then manually sow the seeds, and finally cover the seeds with a tractor. The mechanical operation costs are high, and it is not suitable for a small amount of farmland. In addition, the artificial sowing of rice seeds is not uniform, and the emergence of seedlings is not uniform. It is easy to cause uneven density, and it is necessary to refill the seedlings after emergence, and the depth of the tractor cover seeds is different, resulting in different emergence times and affecting the growth of rice. Contents of the invention [0003] In order to solve the problems of high cost of mechanized sowing in small and medium-sized farmland in the prior art, uneven artificial sowing, uneven sowing depth, and serious impact on emergence of seedlings, ...
