Electrical control pneumatic seeding device

Abstract

The invention discloses an electrical control pneumatic seeding device which comprises a seed box, two land wheels, a mounting plate, a protection shell and an electrical control pneumatic part. The mounting plate is arranged at the bottom of the seed box; the top of the mounting plate is fixedly connected with the bottom of the seed box; the electrical control pneumatic part is fixed on the mounting plate, and the protection shell is arranged outside the electrical control pneumatic part; the two land wheels are respectively connected with both sides of the seed box by a connection rod of thetwo land wheels. The device disclosed by the invention is simple in structure, convenient to use, reliable to work, time-saving and labor-saving and can efficiently complete the seeding operation ina small region. According to the device disclosed by the invention, by adopting injection-type seeding, seeds only need to be placed into the seed box, then the seeds can enter a funnel-shaped seed missing pipe under the action of the gravity, and the seeds can be injected into leveled soil by a once key switch operation without carrying out operations of ditching and earthing; the seeding processis kept complete and seeding capability is good; power consumption is low; the electrical control pneumatic seeding device is light in weight, does not need to be dragged by agricultural machinery; the land wheels can be well suitable for various terrains.

Description

technical field [0001] The invention relates to an electrically controlled pneumatic seeding device, which belongs to the field of agricultural machinery. Background technique [0002] Seeding machinery is one of the important machinery in my country's grain planting. It is widely used in the planting operations of soybeans, corn and wheat, and the seed pelletization technology has developed rapidly as the need for mechanical precision sowing and high crop yield. . However, due to the vast territory of our country, the geographical, climate, agronomic requirements and economic conditions of various regions are quite different, resulting in a relatively low degree of mechanization of sowing operations in small areas, and large and heavy sowing machinery cannot enter the operation. At this time, The proposal of this electronically controlled pneumatic seeder can not only adapt to the complex terrain of a small area, but also can complete the sowing operation without considerin...

Problems solved by technology

[0003] There are many types of various small seeders, the product models are not standardized enough, the production batches are small, and the reliability and technicality of the whole machine cannot adapt to the rural operations in most communities. With the development of agricultural production, research and development is specially oriented to small It is particularly urgent to use small seeders in rural areas to make up for the inability of large seeders to work efficiently in small areas

For example CN206596370U No. utility model discloses a kind of improved soybean seeding device, although this improved soybean seeding device can realize electric type digging hole and bean seed accurately entering pit and filling soil to soil, but this structure volume is huge, The complex process is not conducive to the operation in a small area
