AI Technical Summary

Technical Problem

When harvesting grains, the scattered straw cannot be maximized, which affects the field management and resource utilization effects, or requires excessive human resources to be collected.

Method used

A multifunctional grain combined harvesting device is designed, including a threshing mechanism and a straw treatment box. The straw treatment box is equipped with a transmission assembly, a cutting unit and a bidirectional feed channel. The extension assembly and pressure unit are controlled by the control terminal to ensure stable transmission and cutting into fine shapes, and finally output to a special collection box through the bidirectional feed channel.

Benefits of technology

It realizes efficient collection and utilization of straw, reduces the discarding of straw in the field, improves the utilization rate of resources, and reduces the demand for human resources.

Abstract

The utility model discloses a multifunctional grain combined harvesting device which mainly comprises a straw processing box, a top plate and a bottom plate. A feeding port is formed in the side, close to a threshing mechanism, of the top plate and the bottom plate. A distance sensor and a pressure unit are arranged at the output end of the top plate through an extension assembly, the distance sensor is connected with an external control terminal, and a transmission assembly is further arranged on the top face of the bottom plate. A variable frequency motor connected with the control terminal is arranged on the inner side wall of the straw treatment box, the output end of the variable frequency motor is connected with a cutting unit, the cutting unit is close to the other side of the pressure unit and the transmission assembly, a cut material collecting part is arranged below the cutting unit, and the cut material collecting part is provided with a two-way material conveying channel. The grain combine harvester solves the technical problems that when the grain combine harvester harvests grains, scattered straw cannot be utilized to the maximum degree and is discarded in the field, field management is affected, the resource utilization effect is reduced, or too many manpower resources are needed to collect the straw through a collecting device.
