Description

Technical Field

[0001] The utility model relates to the technical field of corn threshers, in particular to a combined corn thresher. Background Art

[0002] A corn thresher is usually composed of a frame, a shell, a stripping drum, a stripping grate, a rotating shaft, and a pendulum mechanism on the rotating shaft. When the corn cob enters the shell, it collides with the stripping grate driven by the high-speed rotation of the stripping drum, so that the corn kernels and corn cobs are peeled off. In the prior art, the frame of the corn thresher is welded, which is inconvenient to transport. In addition, during the production, the welding process is used in many places, which is easy to cause environmental pollution and is time-consuming and power-consuming. In addition, due to the welding method, the distance between the pendulum on the rotating shaft and the grate is fixed. If the corn cobs are of different sizes, the separation effect will be poor.

[0003] The patent publication number CN201541490U was retrieved. The patent name is a public material of a corn thresher, and it specifically discloses a corn thresher, including a frame, a feed hopper and a threshing bin. A threshing roller and a matching threshing ridge are provided in the threshing bin. A fixed arm is provided at the rear end of the threshing ridge, and the outer end of the fixed arm is connected to the frame through an adjustment mechanism; a feed grate is provided below the threshing roller; a feed chute and a blower are provided below the feed grate. The part of the feed grate located below the threshing roller is an arc-shaped structure protruding downward, and the outer end of the feed grate and the arc-shaped structure are connected to each other in a horizontal structure. The feed chute is an inclined structure with the left side lower and the right side higher. The blower is arranged at the left end of the feed chute and the air outlet faces the upper right. The outer end of the fixed arm is provided with a thread and passes through the frame and is fixedly connected by a matching adjusting nut. A filter is provided above the threshing ridge.

[0004] By analyzing the above-mentioned public materials, it can be known that the frame in this structure is fixed by welding, which makes it inconvenient to transport after production. In addition, the distance between the rotating shaft and the unloading grate cannot be adjusted. Utility Model Content
