Problems solved by technology

[0003] When grains such as wheat, rapeseed, soybean and rice are threshed to the cleaning stage, when the vibrating screen on the thresher is cleaning the grain grains and straw debris, the fan blows out the large-sized straw debris on the sieve plate. Thresher, the finally screened grain particles are discharged from the body through the grain lifter for reloading treatment; in the process of grain grain discharge, the grain lifter in the prior art uses the discharge baffle on the rotating shaft, the auger or It is a fan blade or a hammer, which uses its rotation to drive the grain to make a circular motion in the grain lifter, and finally is thrown out through the discharge port. However, during the stirring process of the grain lifter shaft, the grain particles are in contact with the discharge structure on the shaft. The area is generally too large to facilitate the rapid discharge of grains, and the rotation speed of the shaft in the grain lifter is the same as the speed of the bow-toothed drum used for threshing, that is, when the feeding amount of the thresher increases, the speed of the bow-toothed drum is the same as that of the grain lifter. The rotation speed of the rotating shaft will exceed 1200 revolutions per unit time, and the accumulation of particles in the grain lifter will increase at the same time. At this time, the discharge structure on the rotating shaft will stir the nearly full grain particles in the closed cavity. The friction between the structure and the particles, as well as between the particles, increases the breakage rate in the process of food discharge, and the breakage rate exceeds 10% in severe cases, exceeding the standard value stipulated by the state

Embodiment 1

[0028] like figure 1 and image 3As shown, this embodiment includes a turntable 1, a flange 2 is fixed on the outer peripheral wall of the turntable 1, and a plurality of ring-shaped and array-distributed hoppers 3 are installed on the flange 2, and the hoppers 3 One end is open and the opening direction is the same as the rotation direction of the turntable 1, the opening end face of the hopper 3 is a rounded rectangle, and the area of ​​the rounded rectangle decreases gradually along the direction that the opening end points to the bottom of the hopper 3; A balance weight 4 is fixed at the center of 70~80mm, and an adjustment bucket 5 with open upper and lower ends is also included. Edge 2 threaded connection.

[0029] When the present invention is in use, the turntable 1 is directly fixed on the rotating shaft of the grain lifter, and the grain particles in the grain lifter grain tank are scooped by using the hopper 3 with an open end and the same opening direction as the...

Embodiment 2

[0034] Such as figure 2 and Figure 4 As shown, this embodiment includes a turntable 1 and a plurality of dischargers 7, the discharger 7 is fixed on the outer peripheral wall of the turntable 1 through a U-shaped clamping part 8, and the discharger 7 is the bottom end An open conical cavity, and the opening direction of the discharger 7 is the same as the rotation direction of the turntable 1; a balance weight 4 is fixed at a distance of 70-80mm from the axis of the turntable 1. When the present invention is in use, through the contact between the arc-shaped end surface of the conical discharger 7 and the grain particles, the particles are quickly collected by the discharger 7, and when they are rotated to the discharge port of the grain lifter, the discharge The particles in the device 7 are ejected to complete the grain particle collection process; wherein, when the conical discharger 7 is in contact with the accumulated grain particles on its open end face, many grain pa...

Abstract

The invention discloses a winnower rotor disc which comprises a rotating disc. The outer peripheral wall of the rotating disc is fixedly provided with a protruding edge. The protruding edge is provided with a plurality of annular hoppers arranged in an array mode. One end of each hopper is provided with an opening, and the opening direction is the same as the rotating direction of the rotating disc. The opening end faces of the hoppers are in a rounded rectangle shape. The area of the rounded rectangle is gradually decreased in the direction from the opening ends to the bottoms of the hoppers. The opening end faces of the hoppers are in the rounded rectangle shape, when the hoppers make contact with piled grain particles, the edges of the opening end faces of the hoppers and the particles act with one another, hammer slices or the whole material discharging faces of a material discharging fan blade does not collide with the particles directly, the inner sections of the hoppers are inverted trapezoid-shaped containing cavities, the collected particles are directly driven to conduct synchronous movement along with the hoppers, the probability that a high-speed rotating material discharging structure crushes the grain particles is greatly lowered, and finally the raised grain particles are discharged out of a material outlet.

Description

technical field [0001] The invention relates to the field of grain threshing, in particular to a grain lifter rotor disc. Background technique [0002] Despite the rapid development of combine harvesters in recent years, due to my country's vast territory, large differences in climate and geographical conditions, cultivated varieties, and planting methods, coupled with unbalanced economic development, the performance of some combine harvesters and some key technologies It is still immature, and the thresher is still an indispensable operating tool in the harvesting of grain crops in my country, especially in mountainous areas, hilly small plots, intercropping and miscellaneous grains. The traditional threshing machine usually adopts the cleaning mechanism of double-layer vibrating screen with fan frame, that is, through clamping feeding, threshing with bow tooth drum and cleaning with fan, it has the characteristics of simple structure, small size, light weight, etc., especia...
