Embodiment 1

[0041] The single-wheel soil tank test bench of the present embodiment has a structure such as figure 1 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, it includes a soil tank system, a drive system, a drag system, a control system and a data acquisition system, wherein the soil tank system is mainly composed of a soil tank body 5 and a walking guide rail 4 arranged along the soil tank body 5, and the soil tank body 5 is Rectangular box structure, which is equipped with test soil 11, the size requirements of the box structure are as follows: its length should be determined as 9 meters according to the requirements of data collection in the stability test stage, the width should be determined as 1.5 meters according to the requirements of the drive system, and the depth should be 1.5 meters. Determined to be 0.8 meters, which can reduce the impact of soil boundary effects on the test. A first truss is arranged laterally in the box structure. The first truss ...

Abstract

The invention relates to a single-wheel soil bin test stand which comprises a soil bin system, a driving system, a dragging system, a control system and a data acquisition system. The driving system comprises a driving support. The driving support is a rectangle frame; the inner side of the rectangle frame is provided with a linear bearing; the linear bearing is internally provided with a vertical guide rod; the lower end of the vertical guide rod is equipped with a bottom board; the bottom board is provided with a vehicle wheel fixation shaft support base; the vehicle wheel fixation shaft support base is internally provided with a vehicle wheel fixation shaft; the vehicle wheel fixation shaft is sleeved by a second deceleration chain wheel; the second deceleration chain wheel is connected with a second driving chain wheel; the second driving chain wheel is connected with a first deceleration chain wheel; the first deceleration chain wheel is connected with a first driving chain wheel arranged on a driving motor; the dragging system comprises a dragging motor; an output shaft of the dragging motor is provided with a first driving gear; the first driving gear is connected with a first reduction gear; the first reduction gear is connected with a second driving gear; and the second driving gear is connected with a second reduction gear. According to the single-wheel soil bin bed stand, development cycle of a vehicle can be reduced effectively, and research speed is accelerated.

Description

technical field [0001] The invention relates to a test platform, in particular to a single-wheel soil tank test platform. Background technique [0002] As far as the applicant knows, the indoor soil tank is a necessary experimental equipment for soil-machine system research, and the existing soil tank is usually used to study the performance of agricultural machinery. Since the 1930s, in order to improve the test accuracy of agricultural machinery, many countries have successively established soil tank test bench systems. Generally, the soil tank test bench is to control the traction speed, plowing depth and the speed of the rotating parts of the agricultural implements under the conditions of simulating the moisture content and firmness of the field soil, and test the pulling force and rotational torque of the agricultural implements during travel. And other parameters, so as to analyze the corresponding relationship between pulling force, torque and traction speed, plowin...
