A drum type safflower picking machine

Abstract

A rotary drum type safflower picking machine comprises a machine frame, a power device, a picking device, a drive device, a safflower collecting box and a pneumatic conveying device, wherein the safflower collecting box is arranged on the machine frame, the pneumatic conveying device is arranged behind the machine frame, the picking device is arranged above the safflower collecting box, and the power device and the drive device are arranged on two sides of the picking device respectively. The machine frame comprises a base plate, a base and a cantilever. The power device mainly comprises an electric motor. The picking device comprises a main rotating shaft, rotary drum type picking frames, picking heads and a bearing, and a working principle is that filament clamping and loosening are achieved through reciprocating motion of moving teeth with respect to fixed teeth. The drive device comprises a coupler, flat keys and a gear. When the rotary drum type picking frames perform rotary motion, the picking heads complete rotation and filament clamping; when the picking heads turn to the position above the collecting box, the filaments are sucked into the collecting box to achieve safflower collection and conveying. The rotary drum type safflower picking machine achieves change from aligning point-to-point type picking to mechanical blind picking in safflower filament picking, improves efficiency and saves production costs.

Description

technical field [0001] The invention relates to a drum-type safflower picking machine, in particular to a safflower picking machine for picking dried safflower or fresh safflower, 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. Therefore, safflower picking equipment is crucial to the development of safflower, and the safflower harvester described in CN102714975A ​​utilizes air blowing force to blow off safflowers, and then collects them; mouth, and then cut; the portable flower picking machine described in CN102860176A uses the scissors at the head of the flower suction pipe to cut and then collects; the negative pressure pneumatic video color difference picking head described in CN103371024A is realized by machi...

AI Technical Summary

Problems solved by technology

Generally, 2-3 crops of safflower can be harvested from growing to withering, that is, the achenes cannot be damaged when picking. Therefore, it is difficult and inefficient to pick safflower by precise positioning when harvesting

[0004] A drum-type safflower picking machine of the present invention provides a mechanical picking method for safflower filaments, which avoids the disadvantage that the existing safflower harvesting must be aligned with the achene, and utilizes the friction and tightening effect between the comb teeth, The extraction of filaments is realized, and the arc-shaped picking surface can meet the picking of safflower filaments at different positions and heights, and the harvesting is completed, which greatly improves the problems existing in the existing safflower harvesting machinery, that is, the precise positioning of achenes must be realized. Broken, serious drop phenomenon, low efficiency
