Description

Technical Field

[0001] This utility model relates to the field of soil trough test bench equipment, and in particular to a soil trough test bench vehicle traveling mechanism. Background Technology

[0002] Agricultural machinery plays a crucial role in agricultural development, significantly improving agricultural production efficiency. With the progress of the times, achieving agricultural modernization has become an inevitable trend and core goal of agricultural development. Against this backdrop, vigorously improving the level of agricultural machinery has become an urgent task. As an important component of agricultural machinery, tillage machinery is diverse in type and widely used, playing a vital role in all aspects of agricultural production. The updating and iteration of tillage machinery, as well as the development of new products, require extensive testing. Traditional field testing faces many challenges, such as difficulty in controlling the farmland environment, limited testing time, long verification cycles, and high costs. These factors restrict the high-quality development of tillage machinery products. Indoor soil trough test benches, with their advantages of short testing cycles, minimal impact from external environments, ability to simulate various soil conditions, and high test repeatability, are increasingly demonstrating their value in the field of tillage machinery research.

[0003] Existing invention patents CN211166867U, CN205981631U, CN115655676A, and CN204359523U describe the driving mechanism of a soil trough test trolley, which uses a roller-guide rail friction method to drive the trolley. This method is prone to slippage between the test trolley and the soil trough under high traction loads, thus reducing the accuracy of the test. Existing invention patent CN104990714A uses a chain drive method, which overcomes the slippage between the test trolley and the soil trough. However, due to the tight and slack side characteristics of the chain, there is a movement lag when the test trolley switches between forward and backward, affecting the position control accuracy of the test trolley. Existing utility model patents CN220819456U and CN115676273A use gears as the drive mechanism and auxiliary wheels to limit the lateral movement of the test trolley. However, the vertical limit is achieved by using the trolley's own weight. When the vertical load is large, this limiting method is prone to displacement. In addition, during testing, the upward arrangement of the rack in this utility model patent makes it easy for dust to accumulate on the rack, reducing its lifespan and accuracy.
