A miniature self-propelled precision seeder for direct seeding of rice and wheat

Abstract

The invention discloses a miniature self-propelled precision seeder for rice and wheat direct seeding test, which comprises a walking tractor, a main body frame, a seeding box, a turning assembly, an adjustment assembly and a driving mechanism; the two sides of the upper end surface of the main body frame are welded Two mounting parts, a connecting frame is welded between the upper ends of the two mounting parts, a connector is welded between the connecting frame and the middle position of the main body frame, and the connector is fixed with the dragging end of the walking tractor; the present invention Through the set L-shaped flat iron lock, fixed knob, seed cleaning hole, rectangular shaft and bearing seat, the seed box can be turned over when the variety is changed during the seeding test of the seeder, and the fixed knob is loosened first when turning over. Then turn the seeding box to rotate the seeding box around the rectangular axis, and then realize the overturning of the seeding box, so that all the seeds in the seeding box overflow from the seed cleaning hole, avoiding the frequent replacement of seeds during the sowing of plots. The seeds are not easy to clean.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a miniature self-propelled precision seeder for rice and wheat direct seeding experiments. Background technique [0002] A seeder is a planting machine that uses crop seeds as the object of sowing. The seeder used for a certain type or a certain crop is often named after the type of crop, such as grain drill, corn hole seeder, cotton seeder, pasture spreader, etc. In wheat and rice cultivation, seeds are planted in the field using a seeder. [0003] But existing planter generally has the following problems in use: [0004] 1. It is inconvenient to pour out the remaining seeds in the seeding box after the sowing is completed; [0005] 2. When adjusting the sowing depth, it is necessary to adjust the height of the openers one by one, and the operation is cumbersome; [0006] 3. It is impossible to accurately adjust the seeding rate during use; [0007] 4. There ...
