Stalk cutting test device and method

Abstract

The invention discloses a test device and a test method for indoor simulating cutting of crop stalks. The knife driving mechanism is installed on one side of the stalk clamping device, and the speed sensor is installed on the roller shaft end of the conveyor belt; the torque sensor is installed on the power input shaft, and the cutter and the rocker link are connected. Install a pressure sensor; use the computer's measurement and control system to collect, record and display the data collected by the speed sensor, pressure sensor, and torque sensor for cutting tests. The device is simple and reasonable, and the operation method is stable and reliable, which fundamentally solves the current stem cutting problem. The problem of test parameter adjustment and real-time sampling and processing of test data.

Description

technical field [0001] The invention relates to a cutting test device for crop stalks and a test method thereof, which can be used to simulate the cutting process of rice, rape, wheat, soybean, corn, sugarcane and other crop stalks in the field indoors. Background technique [0002] At present, the research and improvement of the crop harvesting machine header part mainly includes the influence of the structural parameters and motion parameters of the cutter and the reeling device on the header. However, agricultural field experiments are affected by changes in climate, field conditions and machine parameters. The range of structural parameters and motion parameters of cutters and reeling devices in the header is small, so it is difficult to collect and process signals in real time. The cutting performance of the cutter part is closely related to the cutting speed. The higher the cutting speed, the better the performance. With the increase of the cutting speed, the cutting ...

AI Technical Summary

Problems solved by technology

However, agricultural field experiments are affected by changes in climate, field conditions and machine parameters.

The structural parameters and motion parameters of the cutter and reeling device in the header part have a small range of changes, and it is difficult to collect and process signals in real time

The cutting performance of the cutter part is closely related to the cutting speed. The higher the cutting speed, the better the performance. With the increase of the cutting speed, the cutting resistance also decreases, but the vibration of the header increases and the power consumption increases. It is difficult to determine the law of mutual influence and the best combination of parameters

It is not easy to accurately measure the relative position change of the reel in the reeling device and the loss rate of the header under different speed ratio conditions.

There is an urgent need to design a new type of test device to solve the existing problems, but no literature related to this has been retrieved yet
