Seed metering measuring device, seed metering test platform system and method for detecting seed metering quality

Abstract

The invention provides a seed metering measurement device, a seed metering test platform system and a method for detecting seed metering quality, and provides reliable data support for seed metering and fertilizer discharging performance improvement. The seed metering measuring device comprises a mounting frame, a conveying mechanism, a seed containing grid assembly, a seed guide cylinder and a weighing device, the seed containing grid assembly comprises grid baffles, baffles and a bearing plate, the grid baffles are uniformly distributed on a transmission belt, the baffles are connected to the two sides of the transmission belt, the bearing plate is connected to the transmission belt and located between the baffles, and a seed outlet is formed in the right end of the bearing plate. The seed metering test platform system comprises a rack, a seed box, a seed guide pipe, a distributor, a seed mixing pipe, a seed feeding device, a Venturi premixer, a seed metering device and more than one seed metering measuring device. The method for detecting the seed metering quality comprises the following steps: adjusting the seed metering quantity of the seed metering device, and controlling the blocking sleeve to do reciprocating rectilinear motion along the outer grooved wheel by adjusting a blocking motor; and changing the working rotating speed of the outer grooved wheel by adjusting the rotating speed of the seed metering motor.

Description

technical field [0001] The invention relates to a detection device, in particular to a seed-discharging measuring device, a seed-discharging test platform system and a method for detecting the quality of seed-discharging, belonging to the technical field of agricultural equipment. Background technique [0002] The problem of large consistency differences among rows of pneumatic drill seeders is serious. How to solve the differences in consistency among rows is a key technical bottleneck to improve the operation quality of pneumatic drill drills. Seeding amount detection mainly includes indirect detection method and direct detection method. At present, the seeding uniformity and consistency test of pneumatic seed drill mainly adopts indirect detection method. , by weighing the weight of the seeds in each receiving device, that is, to obtain the average value of the amount of seeds for a period of time instead of the real-time value to perform calculations and comparisons of t...
