An experimental device for raising seedlings in agriculture based on physical ultrasonic detection

Abstract

The invention provides an agricultural seedling experiment device based on physical ultrasonic detection. The device comprises a plant height measuring system, a conveying system and a central processing unit, wherein the plant height measuring system comprises a screw transmission mechanism, a first driving motor, a rotating connecting rod, a linear actuator and an ultrasonic sensor, the conveying system comprises two sets of seedling pot conveying mechanisms, each set of seedling pot conveying mechanisms comprises a conveying bracket, a moving plate, a first driving screw, a second driving motor and a nutrient liquid supply pipe, one side of each conveying bracket is provided with a water supply pipe, and each water supply pipe is provided with a plurality of atomizing spray heads used for spraying water on seedlings. The agricultural seedling experiment device based on the physical ultrasonic detection has the advantages that the moving plates can drive seedling pots to pass througha detection area under the ultrasonic sensor in turn, thereby automatically completing the plant height measurement of the seedlings in the seedling pots, and greatly reducing the measurement time ofthe plant height of the seedlings.

Description

technical field [0001] The invention relates to the technical field of seedling-raising experimental devices, in particular to an agricultural seedling-raising experimental device based on physical ultrasonic detection. Background technique [0002] In the experimental stage of seedling cultivation, in order to improve the quality of seedling cultivation, we often add different nutrient solutions to the seedlings to compare and analyze the effects of different nutrient solutions on the growth of seedlings, so as to obtain the best ratio of nutrient solutions. A very important seedling physical index. In the existing seedling height testing technology, pure manual measurement is still used. When measuring the height, the staff uses measuring tools to manually measure the seedlings one by one and make statistics. Then, the statistical results are input into the computer through subsequent arrangement. , to generate the required statistics, it takes too much time and effort to...

In the existing seedling height testing technology, pure manual measurement is still used. When measuring the height, the staff uses measuring tools to manually measure the seedlings one by one and make statistics. Then, the statistical results are input into the computer through subsequent arrangement. , to generate the required statistics, it takes too much time and effort to measure plant height due to the large number of seedlings
