Row-spacing-adjustable differential seeding mechanism

Abstract

The invention relates to the field of seeders, in particular to a row-spacing-adjustable differential seeding mechanism which comprises a supporting platform, a driving device and a seeding device. The seeding device comprises a plurality of seeders, each seeder is detachably arranged on the supporting platform and comprises a feeding part, a seeding part and a switch part, and the driving devicecomprises a driving component and a driven component. When seeding is needed, the seeders can be arranged on the supporting platform, distance among the seeders can be adjusted, and seeding and planting of multiple plants or seeds can be realized at the same time; the seeds can be conveyed into the seeding part through the feeding part which is closed at this moment, then the driving component isstarted to provide driving force and drive the driven component to move, finally the driven component pulls the switch part to start the seeding part, and the seeders can ditch soil in advance, in this way, the seeds enter ditches through the seeders.

Description

technical field [0001] The invention relates to the field of seeders, in particular to a differential seeding mechanism with adjustable row spacing. Background technique [0002] The planting object of the seeder is the seed of the crop or the coated seed made into pellets. It can be divided into three types according to the sowing method: the vacuum seed sower, the sower, and the hole sower. The planter can precisely control the seeding amount, hole distance and sowing depth. The pneumatic seeding precision seeder developed in the 1970s uses positive pressure or negative pressure airflow to discharge a row of seeds at certain intervals to achieve single seed precision seeding. In addition, there is a mechanical precision seeder. It is a suspended 6-row row crop seeder with fertilization device, which can be used for row sowing and hole sowing of row crops such as soybean, corn and sorghum.

Problems solved by technology

[0003] Existing seeders generally put the seeds into the ditch after ditching, and then cover the soil. In this method, the depth of the seeds buried in the soil varies, and some seeds may only be covered with a thin layer of soil. , it may be exposed after watering, affecting the survival of the seeds, and the development of plants at different depths is not the same

[0004] China's patent publication number: CN108848797A; publication date: 2018.11.23 discloses a small agricultural seeder, including a frame, the bottom of the frame is fixedly mounted with a wheel shaft, and the bottom end of the wheel shaft is movably connected with a roller. The front surface of the roller is fixedly installed with a first pulley, the bottom of the frame is fixedly installed with a vertical bar, and the bottom end of the vertical bar is movably connected with a second pulley, and the first pulley and the second pulley are connected through a belt drive , the front surface of the second pulley is fixedly equipped with a trigger rod, one end of the trigger rod is movably connected to the trigger wheel through the wheel rod, the top of the frame is fixedly installed with a support frame, and the right end of the support frame is fixed A seeding box is installed, and a swivel seat is fixedly installed on the left side of the seeding box, and a curved rod is movably connected to the swivel seat, and a contact ball is fixedly installed on the end of the curved rod near the touch wheel. A seeding door is movably connected, and a baffle plate is fixedly installed on the bottom of the seeding box. The baffle plate and the seeding door are fixedly connected by a telescopic spring. The inside of the box is fixed with a seed box, the top of the seed box is provided with a seeding pipe, the right side of the seed box is fixed with a fixed frame, and the bottom of the fixed frame is fixed with a shelving column. There is a push handle fixedly installed on the right side of the planter. The planter cannot adjust the row spacing during sowing, and the depth of seed sowing cannot be consistent.
