A kind of grain lifting device and corn harvester

Abstract

The invention relates to a seed lifting device and a corn harvester. The seed lifting device comprises a horizontal conveying mechanism, a seed lifting mechanism and a grain discharging mechanism, wherein a discharging port of the horizontal conveying mechanism is connected with a feeding port of the seed lifting mechanism, and a feeding port of the seed lifting mechanism is connected with a feeding port of the grain discharging mechanism; the grain discharging mechanism comprises a first outlet and a second outlet; the first outlet is located on one side of the grain discharging mechanism, and the second outlet is located on the lower portion of the grain discharging mechanism; a rotatable adjusting plate is arranged in the grain discharging mechanism and used for shielding the first outlet or the second outlet, so that switching between a mode of conveying seeds to a cluster collecting device for collection together with clusters and a mode of conveying the seeds to a seed collectingdevice for independent collection is realized, and different demands of users are met. The seed lifting device has the characteristics of simple structure, simplicity and convenience in operation andwide applicability.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a grain lifting device and a corn harvester. Background technique [0002] As the main food crop, corn has a wide range of planting areas in various regions of my country, and the cumulative planting area in the country is about 35 million hectares. Due to the large span of north-south latitude and different accumulated temperature zones in my country, there are various varieties of corn, and the span of corn harvesting seasons is long. There are also differences in the demand for corn harvesters in various regions. The methods of peeling and cleaning the grains into the recycling tank and returning the straw to the field cannot meet the needs of users and farmers in different regions. [0003] In the prior art, the grain collection device has two forms: the grain is directly cleaned and then enters the recovery tank, and is collected separately, or the grain directly enters...

AI Technical Summary

Problems solved by technology

However, the ear box and the grain recovery device on the corn harvester are fixed devices, and the recovery mode of the grain cannot be changed.

If the position of the recovery box is changed to meet the above two grain collection forms, it will be necessary to stop and modify, which not only complicates the operation, but also seriously affects the operating efficiency of the corn harvester, and even has a serious impact on the corn harvesting process.
