Sunflower threshing device for agricultural production

Abstract

The invention discloses a sunflower threshing device for agricultural production. The device comprises a bottom groove, a vertical plate is fixedly mounted on the bottom groove, a discharging hole isformed in the lower left side wall of the vertical plate, and a feeding barrel is vertically and fixedly mounted on the right side wall of the vertical plate; a connecting frame is rotatably providedwith a first rotating roller and a second rotating roller, and a strip-shaped hole is horizontally formed in the side wall of the connecting frame; a limiting baffle is vertically and fixedly mountedat the left end of a sliding rod, the lower portion of a horizontal net plate is horizontally and slidingly provided with a pulling rod, and a scraping plate the lower end of which is slidingly connected with the upper surface of the bottom groove is fixedly mounted at the left end of the pulling rod. According to the sunflower threshing device, through the rotation of the first rotating roller and the second rotating roller, sunflower flowers are rotatably extruded, and sunflower seeds on the sunflowers are primarily separated; the sunflowers on the horizontal net plate are repeatedly kneadedthrough a kneading plate, rapid threshing of the sunflower seeds is promoted, under the limiting effect of a limiting spring, the kneading plate can be tightly attached to the sunflowers while kneading, the sunflowers are fully kneaded, and the threshing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sunflower processing machinery, in particular to a sunflower threshing device for agricultural production. Background technique [0002] Sunflower is an annual herb of the genus Helianthus in the family Asteraceae. The stem is erect, round and angular, hard and covered with white coarse hairs. Widely ovate leaves are usually alternate, with sharp or acuminate apex, 3 veins at the base, coarsely serrated edges, rough on both sides, hairy, and long stalk. Flower heads, 10-30 cm in diameter, solitary on stem tops or branches. Involucral bracts are multi-layered, leafy, imbricate, covered with long bristles, flowering in summer, neutral yellow tongue-shaped flowers on the edge of the inflorescence, not fruiting. The middle part of the inflorescence is bisexual tubular flowers, brown or purple, capable of fruiting. Rectangular oval achenes with lignified skin, gray or black, called sunflower seeds. Native...

Problems solved by technology

[0003] Sunflower seeds, that is, sunflower seeds, are eaten as snacks after frying. Sunflower seeds are obtained by threshing from sunflowers. Most of the threshing operations of sunflower threshing devices use manual manual threshing. The threshing process is slow and the threshing efficiency is low. Sunflower seeds cannot be separated quickly and thoroughly from the sunflowers of the sunflower
