Description

Peanut fertilizing and seeding machine with depth adjusting function

Technical Field

The invention belongs to the field of agricultural seeding, and particularly relates to a peanut fertilizing and seeding machine with a depth adjusting function.

Background

When the peanut no-tillage fertilizing and seeding operation is performed, the power of the tractor is directly transmitted into the middle gearbox of the fertilizing and seeding all-in-one machine through the transmission shaft and drives the left cutter shaft and the right cutter shaft to rotate in a rotary mode, at the moment when the cutters are in contact with the ground, the front rotary tillage cutters cut off partial straws or stubbles and then dig into the ground to form strip-shaped loosening, the straws and the stubbles are pushed to two sides of a fertilizing and seeding position while the fertilizing and seeding furrow opener ditches, the depth-limiting press wheel (roller) at the rear part rotates by friction with the ground under the dead weight, the chain transmission mechanism drives the seed discharging and fertilizer discharging mechanism to discharge fertilizer and seed, the discharged fertilizer and seed enter the furrow opener through the fertilizer and seed conveying pipes and sequentially fall into the grooves, the press wheel (roller) immediately compacts the grooves, and completes the fertilizing and seeding operation without-tillage

When peanuts are planted, the depth is generally about 3-5cm, but the peanut planting method is not suitable for all situations and needs reasonable adjustment. The soil quality of the land can be seen before planting, if the land is sandy, the planting depth is deeper than clay land, the planting depth of the sandy soil is about 5-7cm, and the planting depth of the clay land is about 3-4 cm. In addition, the method has a certain relation with water, and the arid area can be deeply planted, but the reverse is shallow planting.
