Suspended pendulum soil covering device for rice mechanical direct seeding

Abstract

The invention discloses a mechanical direct-seeding pendulum type rice covering device which comprises a covering plate, a swinging rod, a mounting plate and a driving disk, wherein the swinging rod is connected with the covering plate, the mounting plate is rotatably connected with the middle of the swinging rod, and the driving disk is arranged on the mounting plate and drives the swinging rod to swing. Mounting holes are formed in the periphery of the surface of the mounting plate, a transmission shaft of a seed-metering device penetrates a middle via hole of the mounting plate and is connected with a middle shaft hole of the driving disk, a swinging rod driving column is arranged on the external circumference of the driving disk, a slotted hole is formed in the upper portion of the swinging rod, the body of the swinging rod driving column is slidably connected with the wall of the slotted hole, the lower end of the swinging rod is connected with the covering plate through a soil covering mounting plate, and the swinging rod reciprocates along with rotation of the swinging rod driving column when the driving disk rotates. The covering device solves the problem of bird damage, rat damage, rain wash, sunlight exposure and low temperature after directly seeding and particularly effectively solves the problem that early rice in double cropping rice areas is easily affected by cold spell in later spring, and direct-seeding full-stand rate is ensured.

Description

technical field [0001] The invention belongs to the field of soil-covering machinery in agriculture, and in particular relates to a suspension-swing type soil-covering device for rice machinery direct seeding. Background technique [0002] Rice is the main food crop in my country, with an annual planting area of ​​about 30 million hectares, accounting for 30% of the country's grain planting area and 20% of the world's rice planting area. With the transfer of rural labor and the application of high-efficiency herbicides, rice direct seeding technology has become more and more popular among farmers. At present, when rice is sown directly, the rice seeds are mostly sown on the mud surface, which is easily affected by bird damage, rodent damage, rain erosion, sun exposure, low temperature, etc. It is even more difficult to guarantee the emergence rate. Therefore, it is of great practical significance to study soil covering technology and equipment to solve a series of problems...
