Seeding device with dual seed adding devices

Abstract

The invention relates to a seeding device with dual seed adding devices. A machine frame is provided with two vibration seed disc devices, two seed absorption devices, two seed adding devices, a pneumatic supply device and a controller. The controller is electrically connected with the vibration seed disc devices, the seed absorption devices, the seed adding devices and the pneumatic supply device. Each vibration seed disc device comprises a trapezoidal seed box, a vibrating plate, an adjustable horizontal baffle, a linear bearing, an electromagnetic vibrator, a vibrating spring and an L-shaped connecting frame. According to the seeding device with the dual seed adding devices, a cylinder is utilized to push an ejector pin to move to eliminate blocking objects in a seed suction nozzle in the seeding device; through the adjustment of the adjustable horizontal baffle, the levelness of the disc surface of each vibration seed disc of the seeding device is adjusted; by adoption of the mobile seed adding devices, seeds are added evenly quantitatively; and an air suction vibration principle is adopted so as to perform automatic precise seeding.

Description

technical field [0001] The invention belongs to the technical field of sowing, and in particular relates to a sowing device equipped with double seeding devices. Background technique [0002] my country is a large agricultural country. With the advancement of science and technology, agricultural mechanization has become a trend. High-efficiency and precision seeding plays a very important role in promoting agricultural production. [0003] The existing air-suction seeder cannot realize multiple functions in one. For the air-suction planter, the seeds are easy to block the suction nozzle, resulting in the inability to suck the seeds in the next step. During the vibration of the vibrating seed plate, how to Adjust the levelness of the vibrating seed disk surface. When the seeds in the seed box are at a certain amount, the seeds should be added evenly in time. How to add seeds precisely and quantitatively? A seeding device equipped with a double seeding device can prevent seed...
