Description
Technical Field
[0001] The utility model relates to the technical field of plant cultivation, in particular to a double-axis multifunctional seeder. Background Art
[0002] A seeder is a planting machine that sows crop seeds. It is used for a certain type or crop and is often named after the crop type, such as grain drills, corn hole seeders, cotton seeders, forage spreaders, etc. In the 1st century BC, China had promoted the use of plows, which were the earliest drill seeding machines in the world and are still used in northern dry farming areas. The double-axis seeder described in publication number CN213603108U has a rear baffle plate in the front of the rear shield that extends downward vertically to change the angle of the flying soil on the rear shaft, so that the flying soil can be thrown vertically downward, solving the problem of flying soil blocking the seeds. A seed scattering plate is added to evenly scatter the seeds from the rear shield. This can achieve a high germination rate, uniform germination, increase yield, reduce seed utilization, and reduce fuel consumption per acre of land. However, the prior art still has defects:
[0003] 1. A bent and fixed soil pressing plate is added under the rear beam of the prior art rotary tiller, and the angle between the main plate and the connecting plate is 149.5 degrees, which can press down the flying soil brought up by the rotation of the front axle and change its direction, so that the flying soil will not be thrown backward and upward, ensuring that the sowing surface is flat and provides excellent conditions for sowing. The front of the rear shield is changed to a vertical plane extending downward to form a rear baffle, which can change the throwing angle of the flying soil of the rear axle, so that the flying soil can be thrown vertically downward, solving the problem of flying soil blocking the seeds. However, the prior art only uses the front and rear rotary tillage shafts to blow the soil and cover it on the seeds, and no furrow opener is set to open furrows, so that the seeds may be scattered on the land in a relatively scattered manner, and it is impossible to form a straight line of uniformly arranged planting, and it is impossible to adjust according to the sowing depth of different seeds, and the scope of application is not wide enough.
[0004] 2. The existing technology adds a seed scattering plate to make the seeds evenly scattered from the rear shield. It can achieve a high germination rate, uniform germination, increase yield, reduce seed utilization, and reduce oil consumption per acre of land. However, the existing technology only has one set of sowing tubes, so that only one line of land can be sown at a time, which greatly reduces the sowing efficiency. Utility Model Content
