Smart Wheat Wide Seedling Belt Precision Sowing Mechanism

Abstract

The invention relates to an intelligent wide-seedling zone precision sowing mechanism for wheat. The intelligent wide-seedling zone precision sowing mechanism for wheat comprises a seed box, a seed taking roller, a suction device, a seeding motor, a controller, a plurality of seed guide pipes, a wide-seedling zone opener, and a suppression mechanism, wherein the seed box is fixedly mounted on a frame, upper and lower openings are formed in the seed box, the lower opening is connected and communicated with a cylindrical housing, and openings are formed in the left side surface and the bottom of the cylindrical housing; the seed taking roller is mounted in the cylindrical housing, an air guide shaft is mounted in the seed taking roller, and the left end of the air guide shaft extends out of the left side surface of the cylindrical housing; the suction device is mounted at the left end of the air guide shaft, and comprises a negative pressure pipe, a positive pressure pipe and a double-acting fan; the seeding motor is positioned at the right end of the seed taking roller, and the rotating shaft of the seeding motor is connected with the seed taking roller; the controller is connected with the seeding motor; the seed guide pipes are vertically mounted under the bottom opening of the cylindrical housing; the wide-seedling zone opener is mounted in front of the seed guide pipes, and a soil coverer is suspended behind the wide-seedling zone opener; the suppression mechanism is mounted on the frame and positioned behind the cylindrical housing.

Description

technical field [0001] The invention relates to an agricultural mechanical mechanism, in particular to an intelligent wheat wide seedling belt precision sowing mechanism. Background technique [0002] "Precision seeding" technology is one of the modern agricultural production technologies of "saving costs and increasing efficiency" promoted by the state. It is an important technical means for the development of agriculture from rough planting methods to intensive and precise planting. Wheat wide seedling belt single-grain precision sowing technology is to change the traditional dense row sowing seed crowding into a wide sowing seed dispersion seed sowing. The single-row sowing width of wheat is widened from the traditional 2-3 cm to 8-10 cm. Inner wheat seed branches are evenly distributed, with large growth space, avoiding competition for fertilizer, water, and light, achieving thick tillers, well-developed root system, increasing panicle weight, and improving lodging resis...

AI Technical Summary

Problems solved by technology

[0004] 1. Semi-precision sowing machines are mainly used, which cannot meet the technical requirements for single-grain precision sowing in wide seedling belts of wheat, and the results of ditching and uniform sowing cannot meet expectations;

[0005] 2. The existing wide seedling belt precision seeder metering device is mainly a hole wheel type metering device, which is not suitable for high-speed operation and other problems, which restricts the production efficiency of wheat sowing operations;

[0006] 3 The traditional air-suction seed metering device is only suitable for single-row single-grain precision seeding operations of wheat. Due to the narrow sowing width, problems such as lack of seedlings, broken ridges and pimple seedlings occur. Difficult to improve work efficiency
