A pressure monitoring device and monitoring method for sowing monomers

Abstract

The invention relates to the field of agricultural intelligent machinery, and discloses a pressure monitoring device for sowing monomers and a monitoring method thereof, wherein the pressure monitoring device includes: a pressure sensor and a host computer; Obtain the force of the ground on the depth gauge wheel in real time; the upper computer is connected with the pressure sensor, and is used to convert the real-time force of the ground to the depth gauge wheel into the actual pressure of the depth gauge wheel on the ground . The pressure monitoring device provided by the present invention is provided with a pressure sensor at the depth gauge wheel, and through the upper computer, the force of the ground on the depth gauge wheel acquired by the pressure sensor in real time is converted into the actual pressure of the depth gauge wheel on the ground, thereby achieving real-time The purpose of dynamically monitoring the pressure of the depth-gauge wheel on the ground is to provide a basis for subsequent control of the pressure of the depth-gauge wheel on the ground.

Description

technical field [0001] The invention relates to the field of agricultural intelligent machinery, in particular to a pressure monitoring device for sowing monomers and a monitoring method thereof. Background technique [0002] During the sowing operation, the ground pressure of the single profiling mechanism directly affects the growth and development of the seedlings in the later stage. Research has shown that too little pressure can lead to plants with shallow root systems, and too much pressure can cause overcompaction of the soil near the roots, limiting root growth, both of which lead to yield loss. Therefore, it is particularly important to dynamically monitor and control the pressure of the sowing monomer. [0003] The existing sowing unit mainly realizes the sowing depth and pressure control through the passive mechanical profiling mechanism, which mainly includes parallel four-bar linkage, depth-limiting wheel, tension spring and profiling adjustment mechanism; it r...

AI Technical Summary

Problems solved by technology

Due to the continuous reduction of seeds in the seed box and fertilizer in the fertilizer box during the operation process, the change in the weight of the whole machine caused insufficient pressure on the ground of the sowing unit, resulting in insufficient sowing depth and even the phenomenon of bare seeds

[0004] Although the existing sowing unit control mechanism can realize sowing depth profiling and simple pressure adjustment, due to the wide variety of soil conditions and surface conditions, the number of tension springs and pre-tightening forces required are also different, so it is very inconvenient to use and adjust. Especially in the case of stubble coverage and uneven ground, the profiling effect needs to be further improved, and at the same time, it is impossible to detect and control the ground pressure of the profiling wheel in real time
