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

Abstract

A drum-type safflower silk picking head with comb teeth friction clamping includes fixed comb teeth, fixed comb teeth rails, moving comb teeth, push-pull electromagnets, a rotating main shaft, a power shaft, and an electromagnet mounting seat. Its main feature is that the rotating shaft is connected to the power shaft, the fixed comb is fixed to the rotating shaft, the moving comb is embedded in the track of the fixed comb, and its two ends are connected with the push-pull rod of the push-pull electromagnet through bolts, and the connection part is an opening. The slot can adjust the distance between the push-pull electromagnet and the moving comb teeth. An electromagnet mounting seat is welded on both sides of the rotating main shaft, and the push-pull electromagnet is fixed on the electromagnet mounting seat. The tooth ends of the comb teeth have radians, and the tooth surface is knurled, which can increase friction and ensure that the achenes are not damaged, and the filaments and achenes are separated. A total of 8 sets of comb teeth in the picking head are evenly distributed on the drum. The relative displacement of the movable and fixed comb teeth of the present invention is smaller than the minimum diameter of the safflower stalk, pedicel and achene. It can realize safflower picking from aiming at flower and fruit picking filigree to mechanical blind picking, improving work efficiency and saving 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
