A two-way seeder for grain

Abstract

A bidirectional grain seeding machine comprises a machine frame, an engine, front wheels, a lifting wheel and a material bin, wherein the engine is arranged at the front end of the machine frame, driving axles are arranged on two sides of the machine frame, the front wheels are arranged on two sides of the driving axles, and each driving axle is connected with the inner sides of intermediate shafts on two sides of the machine frame through a first driving mechanism. The lifting wheel is connected and fixed to the middle of the machine frame through a lifting rod, and a lifting handle is arranged at the top of the lifting rod. The material bin is fixedly arranged at the rear end of the machine frame and is wholly strip-shaped, multiple discharging bin bodies are arranged in the material bin in the length direction, blanking holes are formed in the bottoms of the discharging bin bodies, blanking pipes corresponding to the blanking holes are arranged at the bottom of the material bin, and a group of symmetrical valve strips is arranged at the bottoms of the blanking holes and the blanking pipes of the material bin in a sliding mode. The bidirectional grain seeding machine is simple in structure, low in manufacturing cost, wide in application range, capable of achieving bidirectional seeding and flatly pushing the land where grains are to be seeded, uniform in seeding density and good in seeding effect.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a two-way grain seeder. Background technique [0002] The 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. According to the sowing method, it can be divided into spreader, drill, hole sower and so on. Most of the existing planters have complex structures, high manufacturing costs and high weight, and are mainly suitable for planting crops in plain areas, but are not widely used in hilly areas. In these hilly areas, artificial seeding is mostly used, making seeding The efficiency is extremely low, manpower is wasted, and the income is very small; in addition, most of the existing seeders have an integrated one-way sowing structure.

AI Technical Summary

Problems solved by technology

Most of the existing planters have complex structures, high manufacturing costs, and high weight. They are mainly suitable for planting crops in plain areas, but they are not widely used in hilly areas. In these hilly areas, artificial seeding is mostly used. The efficiency is extremely low, manpower is wasted, and the income is very little; in addition, most of the existing planters have an integrated one-way sowing structure. During the turning process of the equipment, it is easy to cause repeated sowing turning to the inside, while the sowing density turning to the outside is low. , the sowing effect is poor; and the traditional seeder does not have the function of flattening the ground, if the grain seeds are spread on the uneven ground, it will seriously affect the rooting and germination of the seeds, and the sowing uniformity is poor
