Abstract
The utility model discloses a seed-metering wheel of a rice seedling raising seeder and relates to parts of seeders. The seed-metering wheel comprises a cylindrical seed-metering wheel main body part and end covers connected to two ends of the seed-metering wheel main body part, wherein holes are formed in an outer surface of the seed-metering wheel main body part; the holes are uniformly formed in the outer surface of the seed-metering wheel main body part in a linear groove mode; each row of holes comprises an arc-shaped seed filling groove, a seed filling inclined surface connected with one side of the seed filling groove, and a seed charging inclined surface connected with the other side of the seed filling groove; each row of holes is uniformly segmented into (n-1) independent holes through n blade grooves; n is a natural number of more than 14. The seed-metering wheel of the rice seedling raising seeder is high in seed-metering uniformity, and the precision seeding of the seeder is realized.
Description
Technical field
The utility model relates to a kind of parts of sower, particularly a kind of seed wheel of rice raise rice seedlings sower.
Background technology
Rice raise rice seedlings sower by planting seed to before in seedling-cultivation plate, need to seed be arranged by seed wheel, then by planting seed in seedling-cultivation plate.There is easily loosening and seeding shortcoming not uniformly of end cap in the seed wheel of existing rice raise rice seedlings sower, seeding is inhomogeneous easily causes the phenomenons such as the every cave strain of rice shoot number is inhomogeneous, density is high, directly affects seedling quality, does not meet machine transplanting of rice requirement.
Summary of the invention
The purpose of this utility model be to provide a kind of seeding uniformity high, be beneficial to the seed wheel that sower is realized the rice raise rice seedlings sower of precise sowing.
The technical scheme that the utility model adopts is for achieving the above object: a kind of seed wheel of rice raise rice seedlings sower, comprise seed wheel main part cylindraceous and be connected to the end cap at seed wheel main part two ends, seed wheel main part outer surface is provided with type hole, described type hole linearly groove is evenly arranged on the outer surface of seed wheel main part, every row's type hole comprises respectively kind of the groove that fills that is circular arc, be connected to and fill filling kind of inclined-plane and being connected to the inclined-plane of charging seed that fills kind of groove opposite side of kind of groove one side, every row's type hole is evenly divided into n-1 independently type hole by n insert groove, n is greater than 14 natural number.
Further technical scheme of the present utility model is: described in the charge seed gradient on Yu Chongzhong inclined-plane, inclined-plane equate, and the width on the inclined-plane of charging seed is larger than the width that fills kind of inclined-plane.
Described seed wheel main part two ends cave inward respectively and are provided with groove, and the end cap at seed wheel main part two ends is positioned in groove and by screw and fixes respectively.
The seed wheel of the utility model rice raise rice seedlings sower has following beneficial effect: fill kind of an inclined-plane filling the one side setting of kind of groove, being beneficial to seed enters each and fills in kind of groove, easily improve the seeding uniformity, width is set is greater than the inclined-plane of charging seed that fills kind of inclined-plane filling kind of groove opposite side, be beneficial to seed is launched smoothly, for sower, realize precise sowing effective guarantee is provided, through facts have proved, adopt the sower of the utility model seed wheel to sow, compare with the common blanket shape sowing quantity of growing seedlings, every dish hybrid rice seeding quantity, at 65-125 gram, is saved seed and is reached more than 50%; Groove at seed wheel main part two ends is installed end cap, avoids seed wheel that screw loosening occurs in During Process of Long-term Operation, thereby causes end cap loosening.
Below in conjunction with drawings and Examples, the seed wheel of the utility model rice raise rice seedlings sower is further described.
