Mechanical continuous threshing device for agricultural harvesting

Abstract

The invention provides a mechanical continuous threshing device for agricultural harvesting, and relates to the technical field of threshing devices, the mechanical continuous threshing device comprises a shell, a threshing part, a screening part, a driving part and a cleaning part; two fixed seats are symmetrically welded on the shell; the two fixing seats are each of a rectangular plate-shaped structure, and two fixing bolts are connected to each fixing seat in an inserted mode. Four elastic telescopic rods A are mounted on the bottom end face of the top plate, and a mounting seat is mounted at the head ends of the four elastic telescopic rods A; the mounting seat is of a concave structure, and stop levers are welded on the mounting seat in a linear array shape; the blocking rod is of a cylindrical rod-shaped structure, protrusions A are welded to the blocking rod in a linear array shape, and the protrusions A form a retarding structure when the sunflowers move, so that the threshing effect is improved, and the problems that firstly, the sunflowers move fast during threshing, the threshing effect is not obvious enough, and repeated threshing needs to be conducted are solved; and secondly, the problem that residues are doped in the seeds during threshing is solved.

Description

technical field [0001] The invention relates to the technical field of threshing devices, in particular to a mechanical continuous threshing device for agricultural harvesting. Background technique [0002] Sunflower is a plant of the order Platycodon, Compositae, and the genus Helianthus; it is named after the inflorescence rotates with the sun. When threshing the sunflower, the sunflower needs to be dried first, and then threshed after drying. Currently, the sunflower is threshed. The threshing is often achieved by vibration. At present, when the sunflower is vibrated and threshed, there will be residues mixed in the seeds, and subsequent cleaning is required. [0003] However, as far as the current mechanical continuous threshing device for traditional agricultural harvesting is concerned, first of all, the sunflower moves faster in the existing device during threshing, the threshing effect is not obvious enough, and multiple repeated threshing needs to be performed; Whe...

Problems solved by technology

[0003] However, as far as the current mechanical continuous threshing device for traditional agricultural harvest is concerned, first of all, the existing device moves faster when the sunflower is threshing, and the threshing effect is not obvious enough, and repeated threshing is required; secondly, the existing device is threshing. When the seeds are mixed with residues, the screening effect is not obvious enough
