Annular soil contact test device

Abstract

The invention discloses an annular soil touch test device, which relates to the technical field of soil touch test devices and comprises an upper track, a lower track, a double-track circulating mechanism arranged in the upper track, a speed reducing mechanism arranged in the lower track and an outer track rotating mechanism arranged on the outer side of the lower track, the double-track circulating mechanism comprises a first motor, a first rotating column, a power plate and clamping seats, the first motor is provided with a first motor shaft, the first rotating column is movably connected with the first motor through the first motor shaft, the other end of the first rotating column is fixedly connected with the side wall of the power plate, and the two clamping seats are symmetrically arranged on the side wall, away from the first rotating column, of the power plate along the central axis of the power plate; according to the invention, the external gear and the internal gear are in contact and perform meshing rotation, so that internal single-rail rotation is realized, the fixed ring and the external rotating assembly are driven to rotate, and the sliding seat in the rotating assembly is movably connected with the upper rail to perform external single-rail rotation, so that an annular groove and a test vessel in the annular groove are driven to rotate for testing.

Description

technical field [0001] The invention relates to the technical field of soil contact test devices, in particular to a ring-shaped soil contact test device. Background technique [0002] The so-called soil-touching test device is a key component of planting machinery. It can carry out corresponding ditching, covering and suppression processes in the field according to the agronomic requirements of different crops. The germination rate of seedlings is also related to the balance, stability and energy consumption of the whole machine. [0003] At present, there is no relevant information and data in my country on a soil contact test bench that can simulate field conditions and conduct agricultural machinery wear and reliability tests on working parts. The temperature difference between the north and the south of China is large, and outdoor tests are affected by seasons, climates, temperatures, etc. Due to the influence of environmental factors, the reliability test of agricultur...
