Small-grain crop precision seeder

Abstract

The invention discloses a small-grain crop precision seeder, and relates to the technical field of agricultural machinery design. The precision seeder comprises a rack, a ditching device, a seed metering device, a pressing device and a soil collecting device, wherein the seed metering device is located behind the ditching device; the pressing device is located behind the seed metering device; thesoil collecting device is located between the seed metering device and the pressing device; the soil collecting device comprises a soil collector and a soil collecting spring; the soil collector is rotationally arranged on the rack through a soil collecting pin shaft, one end of the soil collecting spring is connected with the rack, the other end of the soil collecting spring is connected with thesoil collector, and the soil collector is in an inclined state. The precision seeder has the advantages that the soil collecting device can quickly cover soil pits where seeds are sown by using a dugsoil body after seed sowing, the covering effect is good, and the operation efficiency is improved. The ditching device, the pressing device and the soil collecting device are all in a floating stateand all can be adjusted, the seeder can be freely adjusted according to different heights of soil layers, and the profile modeling purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery design, in particular to a precision seeder for small-grain crops, which is mainly used in the sowing operation process of small-grain crops. Background technique [0002] Seeding is an important part of the process of planting crops, and its operation effect directly affects the planting effect of crops. The importance of its operation can be seen from this. With the rapid development of modern agricultural technology, there are many types of seeders. Direct operation indicators such as method and work efficiency have been greatly improved, which has greatly changed the operation method of crops. [0003] At present, there are too many types of seeders on the market, and there are flaws in the precision seeding process. In the process of collecting soil, the soil is often returned to the pit by relying on the inertia of the soil block itself, and it does not have the ability of pro...

Problems solved by technology

[0003] At present, there are too many types of seeders on the market, and there are flaws in the precision seeding process. In the process of collecting soil, the soil is often returned to the pit by relying on the inertia of the soil block itself, and it does not have the ability of profiling. Fundamentally solve the problem of mechanism copying, which seriously affects the effect of sowing operations, operation efficiency and the quality of sowing of the whole machine; at the same time, with a large number of rural laborers migrating to cities in recent years, the rural labor force is insufficient, and labor costs have increased. At this stage, there is an urgent need for high-tech High-efficiency, high-quality agricultural machinery to complete the sowing process and improve work efficiency
