Description

Technical Field

[0001] The utility model relates to the technical field of agricultural harvesters, and particularly relates to a special narrow-wide corn harvester for strip compound planting with crawlers. Background Technique

[0002] Corn is one of the important food crops in the world. It is not only used for food processing, but also serves as an important feed source for animal husbandry, aquaculture and aquaculture. A corn harvester is an agricultural machine dedicated to performing operations such as mechanical ear picking, husking, and straw returning to the field when corn is ripe. The emergence of corn harvesters not only improves the efficiency of corn harvesting, but also promotes the modernization of agricultural production. At present, there are various special narrow-wide corn harvesters for strip compound planting with crawlers on the market, but there are still some drawbacks.

[0003] For the existing special narrow-wide corn harvester for strip compound planting with crawlers, the corn straw can be crushed and returned to the field by using a straw chopping device. However, when general corn harvesters harvest corn, a large amount of dust and debris will be generated, which will cause the baffle in front of the harvester to be blocked by the debris, affecting the operator's line of sight. At the same time, when corn is harvested and enters the collection box through the conveying box, a large amount of leaves will be carried during corn harvesting, and these leaves are redundant. If not cleaned, it will affect the subsequent weighing of corn. Secondly, after the corn enters the collection box, if there is no loading mechanism, it will cause problems such as the hopper being full and unable to continue loading. For example, the Chinese utility model patent with the authorization announcement number CN202153863U discloses a corn harvester, which includes a motor vehicle frame provided with front walking wheels and rear walking wheels. A ear picking table is installed at the front end of the motor vehicle frame, and a grain box is installed at the rear end of the motor vehicle frame. Straw chopping devices are respectively arranged on both sides of the bottom of the rear end of the ear picking table. The utility model can crush and return the corn straw to the field and can automatically unload grain. However, this device can crush and return the corn straw to the field by using a straw chopping device. When general corn harvesters harvest corn, a large amount of dust and debris will be generated, which will cause the baffle in front of the harvester to be blocked by the debris, affecting the operator's line of sight. At the same time, when corn is harvested and enters the collection box through the conveying box, a large amount of leaves will be carried during corn harvesting, and these leaves are redundant. If not cleaned, it will affect the subsequent weighing of corn. Secondly, after the corn enters the collection box, if there is no loading mechanism, it will cause problems such as the hopper being full and unable to continue loading. Therefore, we propose a special narrow-wide corn harvester for strip compound planting with crawlers to solve the problems raised above. Content of the Utility Model

At the same time, when the corn is harvested and enters the collection box through the conveying box, a large amount of leaves will be carried with the corn, and these leaves are redundant. If not cleaned, it will affect the subsequent weighing of the corn. Secondly, after the corn enters the collection box, if there is no loading mechanism, it will cause the material box to be full and unable to continue loading, etc.
