Abstract
The utility model relates to a spiral combined threshing cylinder, which comprises a main shaft, a winding-proof disc, a front opening conical cylinder, a guide in sheet, a guide in sheet reinforcing plate, a disc-shaped coupler, plate-type spiked rods, spike teeth, bolts, slanting spiked plates, a grass return plate, a barrel and spike teeth reinforcing plates, wherein the winding-proof disc and the front opening conical cylinder are installed at the front end of the main shaft, the plate-type spiked rods are connected with the front opening conical cylinder through the disc-shaped coupler, the plate-type spiked rods are fixed onto the disc-shaped coupler, the spike teeth are welded at the front ends of the plate-type spiked rods, the slanting spiked plates are welded at the rear ends of the plate-type spiked rods, and the barrel is mounted at the rear end of the main shaft. The spiral combined threshing cylinder has simple structure and reasonable design, and has the functions of threshing, separating grains and cutting off and dispersing straws. Besides, the grass return plate welded on the barrel can prevent straws from winding on the rear portion of the main shaft. The spiral combined threshing cylinder has low percentage of broken grain, less brown rice, low trash content and less grain waste, particularly has remarkable effect in maize threshing, and is capable of early harvesting high quality grains.
Description
Technical field:
The utility model relates to a kind of spiral combined type threshing cylinder.
Background technology:
At present, existing combine adopts holoaxial stream, semiaxis stream, cut flow roller device mostly, and its ubiquitous shortcoming is that the shelling percentage of damage is higher, and waste grain phenomenon is comparatively serious, the product quality poor performance, and the cycle in service life is short.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of spiral combined type threshing cylinder is provided, and it has mainly solved existing combine and has adopted holoaxial stream, semiaxis stream, cut flow roller percentage of damage height, problems such as waste grain.The purpose of this utility model be achieved in that spiral combined type threshing cylinder by: main shaft, anti-drum, preceding rise mouthful formula awl tube, importing tablet, importing tablet stiffener, plate-like hookup, board-like spike-tooth bar, spike-tooth, bolt, an inclined spike-tooth plate, return careless plate, cylinder, spike-tooth stiffener formation.Front end at main shaft is equipped with anti-drum and before rises by a mouthful formula awl tube, on mouthful formula awl tube that preceding rises, be welded with importing tablet, the rear end of importing tablet is welded with the importing tablet stiffener, board-like spike-tooth bar has several, it is connected with mouthful formula awl tube that before rises by the plate-like hookup, the plate-like hookup has a plurality of, it is welded on the main shaft, board-like spike-tooth bar is fixed on the plate-like hookup by the bolt 20-25 degree angle that tilts clockwise, two places at first three branch of board-like spike-tooth bar are welded with several spike-tooths, the rear end of spike-tooth is welded with several spike-tooth stiffeners, be welded with several inclined spike-tooth plates at back 1/3rd places of board-like spike-tooth bar, the angle of inclined spike-tooth plate and board-like spike-tooth bar is the 18-25 degree, and cylinder is installed in the rear end of main shaft, is welded with on the cylinder to return careless plate.This product structure is simple, reasonable in design, the effect that adopts the inclined spike-tooth to have threshing, separate seed, cut-out, dispersion stalk, be welded with on the cylinder and return careless plate, can prevent that stalk is wrapped in the rear portion of main shaft, its percentage of damage is low, brown rice is few, percentage of impurity is low, waste grain is few, and it is more remarkable especially to take off the corn effect, can gather in high-quality grain kind in advance.
