Intelligent electric-driven and pneumatic-type wide seedling strip wheat precision and uniformity seed-metering device

Abstract

The invention discloses an intelligent electric-driven and pneumatic-type wide seedling strip wheat precision and uniformity seed-metering device. The device comprises a pneumatic multi-row precisionseed meter arranged on a bearing frame, a row seeding conversion manifold block, a wide seedling strip row ditcher and an intelligent collection control circuit part, wherein a seed transport interface is arranged at the upper end of the pneumatic multi-row precision seed meter; the pneumatic multi-row precision seed meter comprises a multi-circle combined discharge plate driven by a servo motor;a seed cleaning knife mechanism is arranged on the multi-circle combined discharge plate; the row seeding conversion manifold block is connected to the lower part of an outlet of the multi-circle combined discharge plate; the wide seedling strip row ditcher is connected to the lower end of the row seeding conversion manifold block; the intelligent collection control circuit part comprises a speedcollection sensor; the speed collection sensor is arranged on a land wheel shaft of a matched machine, collects a land wheel speed and transmits a signal to a touch terminal; an advance speed of a seeding machine is calculated; and the discharge plate outputs a control signal of driving the servo motor to drive the servo motor, thereby matching a rotating speed of the discharge plate with the advance speed of the machine and achieving the stability and consistency of per mu seeding rate and a set value.

Description

technical field [0001] The invention relates to a high-efficiency, precise, environment-friendly and multi-functional farmland operation equipment, in particular to an intelligent electric-driven pneumatic type wheat wide seedling belt precision and uniform sowing device. Background technique [0002] Sowing is a key link in crop production. Mechanized sowing has the characteristics of high efficiency and stability. It has replaced manual on-demand sowing and has become the main planting mode in the production of field crops and certain-scale economic crops. Wheat is the number one grain crop in my country, with a sown area of ​​24.2 million hectares, and a huge amount of 363,000 tons of seeds consumed annually if the sowing rate is calculated at 10 kg / mu. At present, wheat sowing generally adopts the form of mechanically driven outer sheave. The outer sheave metering device is installed at the bottom of the seed box, and falls into the seeding area of ​​the sheave metering ...

Problems solved by technology

This scheme uses the horizontal axis roller as the seed picking mechanism, which requires the cooperation of positive and negative pressure to complete the suction and cleaning, and the distance between the multi-channel seed introduction tube and the ground is far away, and the large drop will inevitably cause a large variation in the plant spacing after the seeds fall to the ground. The degree is difficult to guarantee and the horizontal axial distance is relatively large, so it is not suitable for multi-row arrangement
