Description
Technical Field
The invention relates to a safflower fruit ball positioning test bed, in particular to a positioning test bed combining mechanical devices and sensor technologies, and belongs to the field of agricultural machinery.
Background
At present, the safflower is picked and is adopted artifical picking mode to pick the safflower, picks inefficiency, and the main problem that restricts the automatic development of picking of safflower is the location problem of safflower, and safflower flowers and fruits ball is not of uniform size, and the height is fallen by mistake, and there is the problem of sheltering from in machine vision location, and a large amount of safflower can not be fine acquire spatial position. The invention provides a safflower fruit ball positioning test bed which obtains fruit ball positions in a mode of a mechanical device and a sensor and obtains parameter configuration with high positioning rate through tests.
Therefore, according to the growth characteristics of safflower plants, namely the diameter of the fruit balls is far larger than the diameter of the stems, the test bed is designed aiming at the spacing of the positioning pieces and the lifting speed of the lifting device, the spacing of the positioning pieces influencing the positioning rate of the fruit balls, the lifting speed of the lifting device and other factors are tested, finally, the parameter combination with high positioning rate is obtained, and the theoretical basis is provided for the automatic picking of the safflower.
Disclosure of Invention
The invention aims to provide a fig ball positioning test bed capable of adjusting the distance between positioning pieces and adjusting the rotating speed of a lifting device.
The invention relates to a safflower fruit ball positioning test bed which comprises a rack, a clamping device, a lifting device and a control system.
The clamping device comprises a clamping movable plate, a clamping fixed plate and a bolt, wherein the clamping fixed plate is fixed on the rack, and the clamping movable plate is connected with the clamping fixed plate through the bolt.
