Seeder with flexible soil covering mechanism

Abstract

The invention relates to a seeder with a flexible soil covering mechanism. A rotary cultivator is arranged at a position, close to a fertilizing furrow opener, so that the end part of a rotary tillagebending knife of the rotary cultivator is contacted with the right front part of the lower part of the furrow opener; the rotating shaft of the rotary cultivator is additionally provided with a plurality of side block cleaning straight knives, the rotating radius of the outermost end of the straight knives is larger than the rotating radius of the outermost end of the rotary tillage bending knife, and the side block cleaning straight knife is close to one side of the fertilizing furrow opener; the flexible soil covering mechanism comprises a supporting structure, the supporting structure supports a vertically arranged upright rod, the middle part of the upright rod is fixedly provided with a chain wheel, and the chain wheel drives the upright rod to rotate together; the lower part of theupright rod is fixedly connected with the center of a disc, a plurality of connecting rings are fixedly arranged around the disc, each connecting ring is connected with a rubber long belt, the head part of the rubber long belt is embedded with a weighting block, and the rubber long belt is made of a flexible rubber material. According to the invention, a positive position mode of fertilizing rightunder seeds is adopted, the fertilizer utilization rate is improved, the flexible rubber long belt can be deformed continuously, and soil adhered to the flexible rubber long belt can fall off automatically.

Description

technical field [0001] The invention relates to an agricultural mechanical device, in particular to a planter with a flexible soil covering mechanism. Background technique [0002] Most of the existing seeders have single functions, and operations such as rotary tillage, ditching, sowing, fertilization, and herbicide spraying must be completed separately by different operating machines, and the number of times the machines are placed in the field is high, resulting in high production costs. [0003] Most of the existing planters adopt the method of direct spreading or concentrated fertilization at the position below the seed side, the utilization rate of fertilizer is low, and the position of fertilization has obvious influence on the absorption and utilization of fertilizer. [0004] The opener is an important part of the seeder. Fertilization in the right position requires the opener to open a deep ditch to apply the fertilizer to a fixed position. In the case of heavy cla...

However, this passive anti-blocking mechanism cannot ensure no clogging when working in sticky and heavy soil, because the clay will stick to the surface of the anti-blocking mechanism, accumulate more and more, and it is not easy to fall off by itself
