Problems solved by technology

[0003] However, most of the existing precision seeders are suspended and driven by the ground wheel, so there are the following disadvantages: 1. The ground wheel drive is unstable. Due to the limitation of the working environment, the ground wheel drive has certain slippage problems; 2. The transmission mechanism is complex, Sometimes it is necessary to manually change the matching sprocket; 3. Real-time adjustment cannot be realized, and the operation depends on the technical level of the operator

Abstract

The invention relates to the technical field of agricultural machinery, and discloses a radar measurement and control precision seeder. The radar measurement and control precision seeder comprises a rack, wherein a seed box and a fertilizer box are arranged on the rack; a precision seeding device is arranged below the seed box; a ditching and fertilization device is arranged below the fertilizer box; a soil covering compacting device is arranged at the rear part of the rack; a speed measuring radar, a controller, an adjustable proportional valve, a hydraulic motor and a seeding driving shaft are also arranged on the rack, and are sequentially connected; the precision seeding device is connected to the seeding driving shaft. According to the radar measurement and control precision seeder, the radar is used for monitoring speed, the hydraulic motor is used for driving seeding, and the seeding rate can be regulated according to the working speed of the seeder, so that predetermined requirements on the seeding rate can be met. The radar measurement and control precision seeder has the advantages of high automation degree, accuracy in seeding rate regulation and control, and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a radar measurement and control precision seeder. Background technique [0002] Sowing is a key operation link in agricultural production. The seeds must be sown into the field within a short sowing time and according to the requirements of agricultural technology, so that the crops can obtain good development and growth conditions. The quality of sowing will directly affect the emergence, seedlings and seedlings of crops, and thus have a great impact on yield. The traditional sowing method is manual, which has low operating efficiency and high labor intensity. With the development of agricultural mechanization, it is gradually eliminated. Mechanized sowing is the trend of agricultural development, suitable for sowing operations in large fields, and has been fully rolled out in major grain producing areas in my country. my country has always emphasized agricultu...
