Sowing machine detection and test platform

Abstract

The invention discloses a seeder detection and test platform, which comprises a platform foundation, and a weighing device, a pressure flow sensor assembly, a seeder lifting device, a positive pressure fan assembly and a negative pressure fan assembly which are arranged on the platform foundation, the platform movement frame is mounted on the platform foundation, and the three-point suspension module, the land wheel driving module, the seed and fertilizer amount detection device and the large-flow fan assembly are mounted on the platform movement frame. And the rear output shaft driving module is mounted on the three-point suspension module. Through integration of all the components, the device can be used for testing and analyzing the rotating speed and torque of a transmission system of a seeder, the seed metering amount and fertilizer metering amount of a seed metering and fertilizer metering system, the airflow pressure and flow in the seed metering and fertilizer metering link and whether seed and fertilizer are discharged from a seed guide pipe and a fertilizer guide pipe or not, and can simulate the influence of the slope of the field surface on the seed metering and fertilizer metering performance.

Description

technical field [0001] The invention belongs to the technical field of farmland seeders in agricultural machinery, and in particular relates to a seeder detection and test platform. Background technique [0002] Sowing is a key link in agricultural production. The seeder realizes mechanized seeding operations by controlling the process of seed migration into the soil and supporting rotary tillage, fertilization, ditching, covering soil and other related operations. In the seeding operation, each series-parallel system module of the seeder will affect the function and performance of the seeder. In order to effectively evaluate the operating parameters and performance indicators of each series-parallel system module, the seeder needs to be sorted through the indoor bench test system before mass production. System, fertilizer discharge system, pneumatic system, transmission system and other key components of the planter are tested and analyzed under different operating conditi...

AI Technical Summary

Problems solved by technology

[0003] Each system module of the seeder will affect the operation performance of the whole machine. If the seeding system is not designed properly, it will lead to missing seeding, seedling shortage, and broken strips, which will affect the quality of seedling emergence and crop yield; Unevenness and blockage of fertilizer pipes reduce the utilization rate of fertilizers; when there are problems in the transmission system, the structure of the planter will be complicated, the transmission efficiency will be low, and the stability and reliability of the whole machine will be affected, and the complex operating conditions on the ground will affect the key components of the planter Performance has a significant impact, but there is currently a lack of a seeder testing and testing platform for systematically testing the structural parameters and performance indicators of the seeder and its key components under different operating conditions, and it is difficult to ensure that the actual field sowing effect of the seeder meets the agronomic requirements of planting
