Problems solved by technology

During corn threshing operation, the operation resistance is large, the broken rate of corn kernels is high, and the quality of threshing operation is reduced. Especially when there are many ear skins of corn ears, the ear skins are entangled on the threshing drum assembly, and the problem is more significant and prominent. Even The machine is not working properly
In addition, none of the existing corn threshers is equipped with a bran suction mechanism, and the corn kernels after removal are mixed with more bran and snow foam, the effect of removing bran is poor, the cleanliness of the corn kernels is low, and the impurity rate is high

Embodiment Construction

[0012] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The corn thresher includes a main vibrating screen 1, a threshing drum assembly 3 and a suction fan 4, and the bran suction bucket 2 and the bran suction duct 5 are installed on the part between the lower part of the threshing drum assembly 3 and the upper part of the main vibrating screen 1. The ends are respectively connected on the chaff suction barrel 2 and the suction fan 4, and the chaff suction barrel 2 is communicated with the suction fan 4; Suction chaff through hole. On the cylinder shaft 7 of the threshing cylinder assembly 3, the nail tooth seat rod 6 is evenly distributed along the circumferential direction, and the nail tooth plate 8 is axially and radially positioned, and the circumferential direction is rotatably sleeved on the nail tooth seat rod 6. The two nail tooth plates 8 are arranged in a helical shape on the drum shaft 7 as a who...

Abstract

The invention belongs to agricultural machinery and provides a corn thresher. A chaff suction barrel is assembled on a position below a threshing cylinder assembly and above a main vibrating screen. The chaff suction barrel is communicated with a suction ventilator through a chaff suction air duct. The cross section of the chaff suction barrel is in a fan-shaped structure. Chaff suction through holes are formed in the side wall of an arc bottom of the chaff suction barrel. Spike tooth seat rods are uniformly distributed and assembled on a rotary barrel shaft of the threshing cylinder assembly along the peripheral direction. Spike tooth plates are positioned in the axial direction and in the radial direction, and circumferentially and rotatably mounted on the spike tooth seat rods in a sleeved mode. Multiple spike tooth plates are arranged and assembled on the rotary barrel shaft in an integrally spiral linear mode. The corn thresher is novel and reasonable in design, simple in structure, low in kernel crashing rate, high in cleaning rate, low in operating resistance, and few in fault.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a corn threshing machine tool. Background technique [0002] Traditional corn threshers all use columnar threshing spikes fixed on the spike seat plate of the threshing drum assembly. During corn threshing operation, the operation resistance is large, the broken rate of corn kernels is high, and the quality of threshing operation is reduced. Especially when there are many ear skins of corn ears, the ear skins are entangled on the threshing drum assembly, and the problem is more significant and prominent. Even The implement is not working properly. In addition, none of the existing corn threshers is equipped with a bran suction mechanism, and the removed corn kernels are mixed with more bran and snow foam, the effect of removing bran is poor, the cleanliness of the corn kernels is low, and the impurity content is high. Contents of the invention [0003] The purpose of the present...
