Abstract
A sowing mechanism of a corn planter belongs to the field of agricultural machinery and comprises a seed box, seed extracters and a sowing machine, wherein the sowing machine comprises a rotation disc and a fixed tray fixed on the frame of the corn planter, and the rotation disc is connected with the fixed tray through a bearing and a shaft; a loop of seed extracters are equidistantly mounted on the edge wall of the rotation disc through screws; an opening matched with the seed box in size is formed in the edge wall of the rotation disc; the fixed tray is fixed on the shaft through the bearing, and the rotation disc is mounted on the shaft; a seed inlet is formed on the fixed tray; and each of the seed extracters comprises a seed case and a seed extraction spoon, the seed case is provided with a rectangular seed-passing opening, and the seed extraction spoon is arranged below the seed-passing opening and is provide with an outlet just facing a seed inlet of the seed sowing machine. The sowing mechanism can only sow only corn seed each time so as to avoid seed waste; and singling the crop in the final-period management is not required, so that the labor intensity is reduced.
Description
Technical field
The utility model belongs to agricultural machinery, is the auxiliary facility of corn drill.
Background technology
Publication number is disclosed among the CN201612014U " a kind of Novel corn planter ", and the sowing number is generally 2 in production practices, particularly runs into the small-size maize kind, the quantity of sowing is 2 ~ 4, and the seed waste is serious, and final-period management needs thinning, time-consuming, labour intensity is large.
Summary of the invention
The utility model aims to provide the sowing mechanism of the few corn drill of sowing number.
The utility model comprises seed-box, inhales kind of a device, seeder, and described suction kind device comprises blower fan, and blower fan connects the seeding carrier pipe of seed-box by pipeline.Power take-off by tractor flows to blower fan with power through power transmission shaft, and the negative pressure that is produced by blower fan with seed sucking-off in the seed-box, is put into dibbler through carrier pipe input seed box by getting kind of a spoon by suction pipe.
Seeder comprises rotating disc, fixed disk, and fixed disk is fixed on the frame of corn drill, and rotating disc is connected with axle by bearing with fixed disk, passes through the equidistant installation one all seed-taking devices of screw on the limit wall of rotating disc; The opening that mates with the seed box size is set on the limit wall of rotating disc, and fixed disk is fixed on the axle by bearing, and rotating disc is installed on the axle.Fixed disk is provided with the seed entrance.
Described seed-taking device by seed box, get kind of a spoon and form, the seed port is set on the seed box, the seed port is rectangular, the below of seed port arranges and gets kind of a spoon, gets kind of a spoon outlet and aims at a dibbler seed entrance.
Described seed box is supporting 133 specifications, for the specification sowing of 133 all corn varieties of present agricultural production;
The specification of 133 corn varieties that the size specification of the seed port of the seed box of each specification and at present agricultural production are all is to coupling.The maize seed of broadcasting different size can be changed the seed box of different size seed port.
The utility model can only be sowed 1 maize seed, can reduce the seed waste, and final-period management does not need thinning, and labour intensity is little.
