Operation power consumption and verification tests of a trenching device for orchards in Xinjiang based on discrete element

Abstract

According to the agronomic requirements of orchard planting pattern and fertilization in Xinjiang, the soil particle models and a soil-trenching device interaction model were established by using discrete element simulation software in order to find out the law of influence of structure parameters and working parameters on the operation power consumption of a segmented cutting trenching device; moreover, its cutting process was simulated according to the response surface test design. According to the results of research on the influence of forward speed, cutter disk speed and cutter disk combination on the operation power consumption of the segmented cutting trenching device, the law of their influence on the operation power consumption in descending order is forward speed, cutter disk combination, cutter disk speed. According to the response surface test result, the following influential factor parameter combination has been obtained: forward speed 815 m/h, cutter disk speed 112 r/min, cutter disk combination A (cut angle 150°, bent angle 60° and working width 133 mm), cutter disk combination B (cut angle 180°, bent angle 90° and working width 166 mm), and trenching operation power consumption-optimization results were verified through field tests. According to the verification, the results showed a high accuracy of the simulation, with a relative error mean of 3.18% between the theoretical value and the field test value. This study can provide a reference for the energy-saving design of orchard trenching devices.

Research and Experiment on the Trenching Performance on Orchard Trenching Device

“…When a complete set of trenching operations is completed, its motion path is a cycloid 33 .In addition to the physical characteristics of the soil particles, the factors that affect the soil cutting by the trenching cutter head in this movement process should also include the rotation speed of the cutter head, the positive and negative rotation speed and the forward speed of the device. In order to study the movement state of the trenching operation, according to the previous research results and the research basis 34 , the EDEM2020 software is used to establish the soil-cutter head interaction model of the coordinate system with the cutter head rotation center as the origin (as shown in Fig 2). The forward speed and rotational speed of the cutter head are defined consistent with the test.…”

Design and optimization of the parameters of the key components for reed harvester

“…The variety of reed was unknown because it grows wild, the reeds were 3000-4500 mm tall, the bottom diameter of reeds was 12-16 mm, and the water content of reed stalks was 41.3%-56.5%. 2 and conveying rate Y 3 as the cutting and conveying indexes, and a 3-factor, 3-level orthogonal test was carried out with a total of 17 groups and 5 repetitions at the center point [24][25][26][27] . The test factors and levels are listed in Table 2.…”

“…The other test parameters were blade length, 120 mm and horizontal distance between the cutting and clamping point, 64 mm. With the failure rate Y 1 , cutting efficiency Y2 and conveying rate Y 3 as the cutting and conveying indexes, and a 3-factor, 3-level orthogonal test was carried out with a total of 17 groups and 5 repetitions at the center point[24][25][26][27] . The test factors and levels are listed in Table2.…”

Targeting optimal power consumption: Optimizing operational parameters for orchard furrowing and fertilizing machine

“…Ma et al [ 14 ] conducted a study on the impact of forward speed, disc speed, and disc combination on the operational power consumption of a segmented furrow-opening device. They observed that the influence on furrow-opening operational power consumption follows the order from most to least significant: forward speed, disc combination, and disc speed.…”
