Comb-tooth friction clamping drum-type saffron threads picking head

Abstract

A comb-tooth friction clamping drum-type saffron threads picking head is provided. The picking head comprises fixed comb teeth, a fixed comb teeth track, moving comb teeth, a push-and-pull electromagnet, a rotary main shaft, a power shaft and electromagnet mounting seats; the picking head is characterized in that the rotary main shaft is connected with the power shaft; the fixed comb teeth are fixed on the rotary main shaft; the moving comb teeth are embedded in the fixed comb teeth track, wherein two ends of the moving comb teeth are connected with a push-pull rod of the push-and-pull electromagnet through bolts and the connecting portion is a opening groove which can adjust the distance between the push-and-pull electromagnet and the moving comb teeth. Electromagnet mounting seats are welded at two sides of the rotary main shaft; the push-and-pull electromagnet is fixed on the electromagnet mounting seats. Ends of the comb teeth are arc and the tooth surface is knurled, which increases friction, guarantees that achene is not damaged and realizes separating of filament and achene. Eight groups of comb teeth of the picking head are uniformly distributed on the roller. The relative displacement of the moving comb teeth and the fixed comb teeth is less than the minimum diameter of the safflower stems, bennets and achene. It can realize the change from aligned flower and fruit picking to mechanical blind picking, improve work efficiency and save production cost.

Description

technical field [0001] The invention relates to a drum-type safflower picking head with comb teeth friction clamping, in particular to a safflower picking head for picking dried safflower flowers or fresh safflower flowers, and belongs to the field of agricultural machinery. Background technique [0002] As a crop with high economic value, safflower is planted in a large area in Xinjiang. Because the maturity period of safflower filaments and achenes is different, they need to be picked separately, and the flowering period is short. At present, some colleges and universities and enterprises have developed a variety of safflower picking equipment, which is crucial to the development of safflower. The safflower harvester described in CN102714975A ​​uses air blowing force to blow off safflower and then collects it; The machine uses the principle of air suction to suck the filaments into the flower suction port, and then cuts; the portable flower picking machine described in CN1...

AI Technical Summary

Problems solved by technology

[0005] A drum-type safflower picking head with comb teeth friction clamping of the present invention provides a mechanical picking method for safflower filaments, which avoids the disadvantage that the existing safflower harvest must be aligned with the achene, and utilizes the gap between the comb teeth The friction and tightening effect realize the extraction of filaments and complete harvesting, which greatly improves the problems existing in the existing safflower harvesting machinery, that is, the precise positioning of achenes must be realized, safflowers are broken, serious falling phenomenon, and low efficiency
