Portable precision seeder for tests

Abstract

The present invention relates to a portable precision seeder for tests. The portable precision seeder for the tests comprises a machine shell, a seed groove fixedly arranged at an upper opening of themachine shell and a seed arrangement opening arranged at a lower opening of the machine shell, a seed arrangement wheel matched with a material discharging opening of the seed groove is shaft-connected in the machine shell, a groove is arranged in an outer surface of the seed arrangement wheel, and the seed arrangement wheel is connected with a shell body of the machine shell through a first torsion spring; and the machine shell is provided with a driving mechanism for driving the seed arrangement wheel to rotate. The portable precision seeder for the tests has simple integral structure and strong universality, can realize sowing of various seeds, and is small in volume, convenient in operation, high in sowing accuracy, convenient for precision sowing for the tests; and a driving rod drives the seed arrangement wheel and an upper duckbilled plate to rotate simultaneously through a pull rope and the operation is convenient.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a portable precision seeder for testing, which realizes precision sowing of crops such as corn and soybeans. Background technique [0002] At present, the density or row spacing tests of corn, soybeans, and wheat rely on manual ditching, on-demand sowing, and soil burial. The depth of ditching is different, which is time-consuming and labor-intensive, resulting in irregular seedling emergence and insufficient density. Therefore, it is necessary to greatly improve the accuracy of sowing. At the same time save manpower and time. [0003] The overall size of the traditional portable seeder is too large, and the seed opening is wide, which may easily cause the seeds to deviate from the predetermined position during sowing, and the seeding speed needs to be slowed down to achieve the experimental results; and the seeder is too heavy, which is not convenient for female researchers...

Problems solved by technology

[0002] At present, the density or row spacing tests of corn, soybeans, and wheat rely on manual ditching, on-demand sowing, and soil burial. The depth of ditching is different, which is time-consuming and labor-intensive, resulting in irregular seedling emergence and insufficient density. Therefore, it is necessary to greatly improve the accuracy of sowing. Save manpower and time at the same time

[0003] The overall size of the traditional portable seeder is too large, and the seed opening is wide, which may easily cause the seeds to deviate from the predetermined position during sowing, and the seeding speed needs to be slowed down to achieve the experimental results; and the seeder is heavy, which is not convenient for female researchers to use

[0004] In view of the problems of large size, low precision and laborious operation of the existing seeders, it is urgent to invent a more compact and relatively high-precision small portable seeder to improve the precision of seed sowing, make the operation steps simpler and faster, and ensure test quality
