Problems solved by technology

The sieve cylinder wrapped outside the rotor of the corn thresher adopts a combined structure of steel wire and flat steel. When the moisture is high in autumn, the corn damage rate is very high. When threshing with skin, the corn husk will hang on the steel wire and affect the threshing effect.
There is also a threshing drum with an extrusion structure. When threshing with skins, corn kernels are easily caught in the skins and discharged from the tuyere, resulting in waste.

Embodiment Construction

[0012] like figure 1 , 2 As shown in and 3, it includes a rotor 1 and a sieve cylinder 2, the outer wall of the rotor 1 is spirally arranged with peeling nails 3, rubbing blocks 4 and cleaning nails 5 from the input end to the output end, and the rubbing block The front end surface and one side end surface of 4 are slopes that play a guiding role, and its top surface is provided with a rib 6 that is consistent with the direction of the side slope. Peeling spikes 3 can peel off the corn husks from the cob in advance, and then squeeze and knead the rubbing block 4 to make the threshing more clean and thorough. Cleaning spikes 5 can shake out the grains caught in the corn husks to prevent loss of grains waste. The ribs on the top of the kneading block 4 can improve the threshing efficiency. Peeling nail teeth 3 quantity is far more than cleaning nail teeth 5, but its height is smaller than cleaning nail teeth. The side slopes of the kneading block 4 are consistent with the di...

Abstract

The invention discloses a roller structure of a corn thresher, and relates to agricultural machines, in particular to an improvement of the roller structure of the corn thresher. The roller structure comprises a rotor (1) and a screen drum (2), an excoriating spike tooth (3), a rubbing block (4) and a cleaning spike tooth (5) are sequentially and spirally arranged on the outer wall of the rotor (1) from the input end to the output end, the front end face and one lateral end face of the rubbing block (4) are slopes which have the guide effect, and a bead (6) coincident with the lateral slope in direction is arranged on the top face of the rubbing block (4). The roller structure has the advantages of being reasonable in structure, low in breakage rate and good in threshing effect. Through the processes of peeling, rubbing threshing and shaking cleaning, the corn threshing effect is better, cleaning is more thorough, and losses of corn in the threshing process is reduced to the maximum degree.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an improvement of the drum structure of a corn thresher. Background technique [0002] Most of the rotors of the existing corn threshers have a nail-tooth structure. When working, the corn cobs are fed from the feed port, and the corn is impacted by the high-speed rotating nail teeth in the drum, and the grains are separated from the sieve holes. The tail is discharged, and the corn silk and skin are discharged from the tuyere. The impact of this kind of structure is stronger during operation, the damage rate of corn kernels is higher, and the corncob is also often broken, which brings trouble to recycling. The sieve cylinder wrapped outside the rotor of the corn thresher adopts a combined structure of steel wire and flat steel. When the moisture is high in autumn, the corn damage rate is very high. When threshing with skin, the corn husk will hang on the steel wire and affect the thre...
