Background

A grain combine harvester, called a combine harvester for short, is a combine harvester for harvesting crops, and is a harvesting machine for directly obtaining grains from the field. The grain combine harvester is mainly used for the combined harvest of wheat crops, and can complete cutting, threshing, separating, cleaning and other operations in one step in the field. When the harvester is used for segmental harvesting, the grain picker is arranged on the harvesting table, the grain strips after being aired can be picked up and spread, and the operations of threshing, separating, cleaning and the like are completed. Threshing machines and mechanical harvesters have greatly increased agricultural productivity over the past century before the advent of combine harvesters. This makes it possible to harvest more grain with fewer workers than before. But an invention later in the last century has improved this efficiency even further. The combine combines the harvesting and threshing machines in one piece, allowing the farmer to complete both harvesting and threshing in a single operation. Thereby saving manpower and material resources and greatly reducing the burden of farmers. When the auxiliary devices (such as a soybean low-cutting device and the like) are added on the grain combine harvester or after proper modification and adjustment, the grain crops such as rice, corn, soybean, millet, overhead and the like can be harvested. The collection of components that direct air or air-fuel mixture into the engine cylinders is referred to as the engine intake system.
