Small multifunctional trolley based on soil bin testbed

Abstract

The invention discloses a small multifunctional trolley based on a soil bin testbed. The small multifunctional trolley comprises a testbed rack, a rotary tillage system, a soil compaction system and a soil leveling system. The rotary tillage system is arranged at the front end of the trolley rack. The soil compaction system is arranged at the rear end of the trolley rack. The soil leveling system is arranged on the trolley rack and located between the rotary tillage system and the soil compaction system. The small multifunctional trolley is an important component of the testbed, integrates rotary tillage, leveling and compaction functions and is assisted by a soil bin and capable of conducting soil bin tests of multiple kinds of working modes, and test results can provide important test data and technological means for soil cultivation component design, selection and failure mode analysis and can provide test conditions for combined rotary tillage component research.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery testing, and in particular relates to a small-sized multifunctional trolley based on a soil tank test bench. Background technique [0002] Soil tillage components are the core components of agricultural machinery, and their soil cutting performance directly affects the energy consumption and farming efficiency of agricultural machinery. Soil tillage components are mainly subjected to complex and randomly changing loads from the plow layer soil. Due to excessive resistance, the soil tillage components often lead to short service life, and even bending and fracture. Therefore, real-time testing of the dynamic load of soil tillage components and the study of their stress characteristics and laws during the tillage process will provide important test data and technical means for the design, selection and failure mode analysis of soil tillage components. It can provide valuable referenc...

AI Technical Summary

Problems solved by technology

The soil-contacting parts test device based on the soil tank test bench that has been reported at present mainly has the following deficiencies: 1. The size and specifications of the soil tank test bench and its trolley are relatively large, and different functions (such as rotary tillage, leveling, compaction) can be realized. etc.) The trolley system is relatively independent; 2. Most of the test devices have a single load test, and the test data is mostly limited to torque; 3. Most of the test devices are aimed at the single-roller structure, and are limited to single-roller single-knife or multi-knife test research; 4. Most test devices are limited to specific tests, and the interchangeability and versatility of working parts are poor
