Pneumatic seed shooting and seeding device

Abstract

The present invention provides a pneumatic seed shooting and seeding device. The device comprises a machine frame provided with travelling wheels and a seeding device arranged on the machine frame, wherein the seeding device comprises a seed box, a typical hole seeding apparatus, a seed guide pipe and a stepping motor, the seed box is arranged on the machine frame, the typical hole seeding apparatus is arranged on the bottom of the seed box, the seed guide pipe is communicated with the typical hole seeding apparatus, and the stepping motor is connected with the typical hole seeding apparatus. The present invention is characterized in that a pneumatic seed shooting device and a PLC (programmable logic control) controller are additionally arranged, and the control end of the stepping motor is connected with the PLC controller; the pneumatic seed shooting device comprises a drive module, a pneumatic seed shooting module and an accelerating tube, wherein the pneumatic seed shooting module is vertically arranged on the middle lower part of the machine frame in a movable mode, the top end is connected with the bottom of the drive module, the control end of the drive module is connected with the PLC controller, and the accelerating tube is fixed on the bottom of the pneumatic seed shooting module. The device directly sows seeds without adopting a ditching device and a soil covering device in a traditional seeder. The device has excellent work performance.

Description

technical field [0001] The invention provides a pneumatic seeding and sowing device for realizing shooting and sowing with high-pressure gas, which belongs to the technical field of agricultural machinery. Background technique [0002] The currently used hole sowing seeder mainly completes the work of ditching, seeding, fertilizer discharge, covering soil and compaction. When the seeder is working, the opener opens a seed ditch on the ground, and the seeds in the seed box are discharged by the seed meter and fall into the seed ditch through the seed delivery pipe. The traditional contact sowing method (direct contact between the opener and the soil) cannot meet the requirements of various advanced agronomic technologies developed in recent years, such as film mulching sowing, precision agriculture, water-saving agriculture and liquid fertilizer fertilization, etc.; Due to the direct interaction between the soil-entry device and the soil, the power consumption is relatively ...

Problems solved by technology

The traditional contact sowing method (direct contact between the opener and the soil) cannot meet the requirements of various advanced agronomic technologies developed in recent years, such as film mulching sowing, precision agriculture, water-saving agriculture and liquid fertilizer fertilization, etc.; Due to the direct interaction between the soil-entry device and the soil, the power consumption is relatively large; when the soil humidity is high, it is difficult to ensure the quality of the seed or even sow; However, there is a distance of the distance between the plants, so that the seed ditch between the plants is not used, which reduces the working efficiency of the opener, and the soil is also plowed when the ditch is opened, which is not conducive to soil protection. If the seeds can be directly sown Into the land, that is, the ditching process is eliminated, and energy saving can also prevent the soil from being plowed repeatedly
