Seed dibbler

Abstract

The invention relates to a seed dibbler. Like a traditional dibbler, the seed dibbler adopts a rotary cultivator to pulverize soil and cover seeds, but is quite different from a traditional seeder about a seeding mechanism, and the seeding mechanism comprises a seeding shaft, a seeding tray, a seed-casting spoon, a lever, a tension spring and a touch wheel. The seeds are taken out form a seed box by a seed-fetching and casting mechanism and cast from the seed-casting spoon into a seeding pipe by utilizing the principles of acceleration and inertia so as to be sent to set positions. The seed dibbler can fetch precise number of seeds, uniformly cast the seeds in the soil, can adjust row distances and planting distances and is particularly suitable for seeding crops unsuitable for drill seeding, such as paddy, rape, soybeans, peanuts, corn, and the like.

Description

technical field [0001] The invention relates to a field seeder. Background technique [0002] At present, the most widely used farmland seed sowing machine is a seed drill matched with a walking tractor - Jiangnan 2BG-6A rice and wheat drill machine. Seeders have been used for three-wheat drills for decades, and the market has reached hundreds of thousands of units. But because this kind of planter has many disadvantages in the structure and the method of adjusting the sowing rate, it uses a circular sowing wheel sleeve with several grooves to rotate in a barrel-shaped seeding box, and adjusts the gap between the gates to adjust the sowing rate. In fact, it is difficult to ensure accurate and consistent control of the seeding rate. Even if the adjustment is very good, it will not take long. Due to the vibration of the tractor, it often causes a section of missed sowing, and a section of multi-seeding. The amount of seeds is large, and it can be used for three-wheat sowing....

Problems solved by technology

But because this kind of planter has many disadvantages in the structure and the method of adjusting the sowing rate, it uses a circular sowing wheel sleeve with several grooves to rotate in a barrel-shaped seeding box, and adjusts the gap between the gates to adjust the sowing rate. In fact, it is difficult to ensure accurate and consistent control of the seeding rate. Even if the adjustment is very good, it will not take long. Due to the vibration of the tractor, it often causes a section of missed sowing, and a section of multi-seeding. The amount of seeds is large, and it can be used for three-wheat sowing.

This kind of seed drill is not suitable for rape, soybean, peanut, corn and other crop seeds. At present, farmers still use manual on-demand sowing, which is not only inefficient, but also labor-intensive. Farmers urgently need a multi-functional sowing with precision on-demand machine

Although many scientific research institutions and agricultural machinery departments are doing research and experiments, so far, an ideal precision seed on-demand planter has not been seen in the market.
