Dibbler qualification rate detection equipment and method

Abstract

The invention discloses dibbler qualification rate detection equipment. The equipment comprises a rack, a dibbler support and a conveying mechanism, the dibbler support and the conveying mechanism arearranged on the rack, a qualification rate detector is arranged on the conveying mechanism and comprises a flow guide mechanism, a position sensor and a signal collector, an opening is formed in thefront end of the flow guide mechanism, and the position sensor is located at the opening. Seeds can pass through the opening, the number and the state of the seeds passing through the opening are collected by the position sensor, and the collected number and state of the seeds are displayed in the signal collector in a pulse signal mode. A dibbler qualification rate detection method comprises thestep of using the dibbler qualification rate detection equipment. By utilizing the detection equipment and the detection method, the detection efficiency and accuracy of the dibbler can be improved.

Description

technical field [0001] The invention relates to a testing device and a testing method for qualified rate of hole seeders. Background technique [0002] Xinjiang is the largest high-quality cotton production base in my country. From 2012 to 2019, the annual cotton production in Xinjiang has increased year by year. The first link affecting cotton production is sowing. The quality of sowing will affect the emergence rate of cotton. This in turn affects cotton yield. One of the most important methods of precision sowing is hole sowing, which uses a precision hole sowing seed meter to sow cotton seeds into the farmland in the form of one hole or one hole with multiple seeds at a certain distance. [0003] At present, it is necessary to test the working performance of the hole seeder before leaving the factory to ensure that the qualified hole seeder goes to the field, which plays a very important role in improving the quality of the enterprise's products. Existing detection meth...

Problems solved by technology

[0004] Manual inspection has the problems of time-consuming and laborious and low inspection accuracy; although the machine vision method can be used to better count the number of discharged seeds, it still has the following deficiencies: the requirements for the cotton conveyor belt are high, and the lawn conveyor belt The background color of the green conveyor belt is heavy, which is not conducive to the contrast between the cotton seeds and the background color. The image contrast of the white conveyor belt is high, but the white conveyor belt is not resistant to dirt and is not suitable for long-term operation. When multiple cotton varieties are superimposed When judging the number of cotton seeds, the accuracy rate will be reduced; light curtain and photoelectric sensor detection not only have problems such as low detection accuracy and poor stability, but also when multiple seeds are discharged at the same time, there is a problem that the number of seeds cannot be judged. Problem, for example, the invention patent application publication number CN110082143 A discloses "an automatic detection device for seed leakage of hole seeder", which mainly uses the seeds to pass through the light curtain sensor under the action of gravity, and uses the light curtain sensor to measure the number of seeds. According to the statistics, it is found through experiments that the time for the free fall of seeds to pass through the light curtain sensor is very short, requiring very high detection sensitivity of the light curtain sensor, and the detection accuracy is low; therefore, based on the above analysis, this application designs a New testing equipment and testing method for qualified rate of hole seeders
