Model Classification Of Different Working Principles Of Farm Corn Combine Harvester

Farm corn combine harvester can be roughly divided into the following forms according to different working principles:

1. Combine harvesting: Use a farm corn combine harvester to complete ear picking, peeling, and gathering (or picking, peeling, and threshing, but the humidity of the grain should be below 23%), and carry out the stalk weighing process (cut into sections for silage or crush and return to the field) Wait for tasks, then transport the ears without bracts to the field, and then thresh them after drying.

The technological process is three consecutive links: picking-peeling-straw processing.

2. Semi-mechanized harvesting

(1) Use a windrower to cut down and place the corn. After a few days of drying, the humidity of the grain drops to 20%~22%. Use mechanical or manual ear picking and peeling, and then transport to the field for drying and threshing; Straw treatment (cut into sections for silage or crushed to return to the field).

(2) Use ear picking machine to pick ears in the growing state of corn (called standing stalk picking), then transport the ears to the field, peel them with a peeling machine, and thresh them after drying; straw treatment (cut silage or Smash to the field). The technological process is: earing-peeling-straw and processing (three links are carried out in stages).

3. Other

(l) Replace the corn header with a grain combine harvester, and complete operations such as ear picking, peeling, (threshing, separation and cleaning) at one time;

(2) Use a windrower to cut down the corn and place it in a zigzag strip shop. A grain combine harvester equipped with a grain picker can pick up and thresh the grain and can also be used for straw field.

The research and production technology of foreign farm corn combine harvester has matured. At present, corn harvesting (including grain and straw silage) has basically realized all mechanized operations in Western countries such as the United States, Germany, Ukraine, and Russia. Since its planting method is mostly planted once a year, the moisture content of corn kernels at harvest is very low.

Most countries use the farm corn combine harvester method of picking the ears and directly threshing corn, such as the United States John Deere Company, Case Company, German Mengle Company, Deutz Company and other farm corn combine harvester, most of which are on the wheat farm corn combine harvester Replace the corn header, and perform the combined harvest of corn by adjusting the speed of the threshing roller and the threshing gap.
