Straw mulching ridge seeder

Abstract

A straw mulching and ridging sowing machine comprises a straw mulching and ridging sowing machine rack (1), a power transmission device located at the front end of the straw mulching and ridging sowing machine rack (1), a rotary cultivator rack (7) located in the middle of the straw mulching and ridging sowing machine rack (1), a pesticide spraying device and a sowing device, wherein the pesticide spraying device and the sowing device are located on the rear portion of the straw mulching and ridging sowing machine rack (1). The sowing device comprises ridgers (11), a sowing boot (12), a press wheel (13) and a sower (15), the sowing boot (12) is located on a ridge face between the two ridgers (11) and is vertically adjustable to adapt to the sowing depth, the sower (15) is located above the sowing boot (12) and driven by the press wheel (13) to rotate to sow seeds, and the press wheel (13) is located between the two ridgers (11) and behind the sowing boot (12) and rolls along the ridge face. The pesticide spraying device sprays pesticide to the ground surface through a pesticide pipe.

Description

technical field [0001] The utility invention relates to the field of agricultural machinery, in particular to a straw-covered ridge seeder. Background technique [0002] Peanut is one of the main economic crops planted in my country. There are two planting methods: flat sowing and ridge sowing. Flat sowing is mainly planted in arid and sandy loam areas in the north. Ridge sowing has the advantages of ventilation, light transmission, high yield, easy irrigation and drainage, etc. It has been vigorously promoted in recent years, and the planting area has continued to expand. The previous ridge sowing of peanuts was mainly on the leveled land. The peanut ridge planter was used to fertilize and sow first, and then use the attached plow or disc to turn the soil, pile up, and ditch to form ridges. Method jobs have the following disadvantages: [0003] ①The ridge surface is narrow and arc-shaped, which reduces the effective growth area of ​​peanut roots, which is not conducive to...

Problems solved by technology

[0004] ② There is a contradiction between the sowing depth and the depth of the furrows. Since the seeds are sown first and then the furrows are turned to form the ridges, if the furrows are deep, the raised soil will cover the ridges and the sowing depth will increase relatively, which is not conducive to seedling emergence.

[0005] ③In summer-sown peanut planting areas after wheat harvest, the straw must be burned or the wheat stalks should be recovered first, then the root stubble must be removed, and then the soil should be prepared for sowing.

[0006] ④Preparing the soil first and then planting seeds will cause secondary rolling of the soil, and waste power and increase costs
