Seed metering test bed capable of automatically recycling seeds

Abstract

The invention discloses a seed metering test bed capable of automatically recycling seeds and belongs to scientific research test equipment. The seed metering test bed is characterized in that a seed metering detection rotary belt assembly which is driven by an electronic motor B and is provided with a friction material layer and a flexible ruler is arranged on a rack in a rotary motion manner; a seed metering system consisting of a funnel type seed box, a seed metering device, a seed metering driving shaft, a driven belt wheel, a transmission belt, a driving belt wheel, a wheel shaft and an electric motor C is assembled on the rack and located on the upper portion of the seed metering detection rotary belt assembly; a friction roller and a first-stage recovered seed transfer tank with a seed cleaning plate are mounted on the rack and located at the starting end and the tail end of the seed metering detection rotary belt assembly respectively; and the first-stage recovered seed transfer tank communicates with the funnel type seed box through a baffle type seed conveying belt assembly driven by an electric motor A and a second-stage recovered seed transfer tank. The seed metering test bed realizes automatic recovery and recycling of the seeds, reduces the test cost, avoids seed waste, is high in detection precision, and saves labor, effort and time.

Description

technical field [0001] The invention belongs to scientific research and test equipment, and mainly relates to a test bench for performance testing of seed metering accuracy, quality, efficiency, etc. of a seed metering device. Background technique [0002] In order to ensure the manufacturing quality and qualified rate of mass-produced seed metering devices and improve the R&D and design level of new seed metering devices, it is necessary to conduct random inspection of batch products and test bench performance of scientific research samples in the process of production and scientific research. In order to ensure that the seeds do not bounce when the seeds are discharged from the seed metering device and fall on the seed metering detection rotary belt assembly, the current seed metering test bench adopts the method of smearing butter on the surface of the seed metering detection rotary belt, and at the same time Check seed spacing by manually measuring dimensions. The above...

AI Technical Summary

Problems solved by technology

The above-mentioned prior art not only causes the test seeds to be contaminated with butter and cannot be reused, resulting in waste of seeds and increased test costs, but also the technical problems of low efficiency, poor precision, and inconvenient operation in the manual measuring scale.
