AI Technical Summary

Technical Problem

In existing rice harvesters, rice husks and roots easily clog the gaps in the cutting teeth during the cutting process, resulting in slower cutting speed, reduced cutting efficiency, and a lack of automatic cleaning function.

Method used

A rice harvesting device including a cleaning mechanism and an adjustment mechanism was designed. The device uses a rotating shaft to drive a pulley and a reciprocating screw to clean the cutting teeth of the machine with brushes. The device also uses a servo cylinder to adjust the lifting and angle of the machine's base frame to adapt to different terrains.

Benefits of technology

It effectively avoids clogging by rice husks and roots, ensuring efficient cutting operations, and can adjust the angle and width of the cutter according to the terrain to improve cutting efficiency.

Abstract

This utility model relates to the field of rice cultivation and discloses a rice harvesting device, including a base. An adjustment mechanism is provided on the top of the base, and a cutting machine frame is mounted on the adjustment mechanism. A rice cutter is fixedly connected to the top of the cutting machine frame. A cleaning mechanism is provided on the base, including a rotating shaft rotatably connected to the inner wall of the base. A pulley A is fixedly connected to the outer wall of the rotating shaft. A bracket is fixedly connected to the right side of the outer wall of the cutting machine frame, and a reciprocating screw is rotatably connected to the inner wall of the bracket. In this utility model, when the device moves, the rotating shaft rotates with the moving wheel, driving the pulley A to rotate. The screw slider, threadedly connected to the reciprocating screw, reciprocates, causing the brush block to slide on the outer wall of the bracket, cleaning the teeth of the rice cutter, preventing rice husks and roots from clogging the gaps between the teeth, and ensuring efficient cutting operations.
