A profiling vibration-absorbing crawler-type walking chassis of a grain combine harvester

Abstract

The invention provides a profiling vibration-damping crawler type traveling chassis of a grain combine harvester. The profiling vibration-damping crawler type traveling chassis comprises a driving control system, a power transmission system, a chassis rack and crawler belt mechanisms, and the crawler belt mechanisms comprise the crawler belt traveling mechanism and the crawler belt support mechanism; the crawler belt traveling mechanism comprises crawler belts, a riding wheel supporting beam, a crawler belt riding wheel, a crawler belt driving wheel, a crawler belt tensioning wheel and a crawler belt load-bearing wheel; the crawler belt support mechanism comprises a crawler belt support main beam, crawler belt vibration damping subsidiary beams, a crawler belt front support beam and a crawler belt rear support beam; the crawler belt front support beam and the crawler belt rear support beam are fixed to the bottom of the chassis rack in the front-rear direction and located on the same straight line; the lower portion of the crawler belt front support beam and the lower portion of the crawler belt rear support beam are jointly connected with the crawler belt support main beam; the lower portion of the crawler belt support main beam is connected with the multiple sets of crawler belt vibration damping subsidiary beams; the bottoms of the crawler belt vibration damping subsidiary beams are both connected with the crawler belt load-bearing wheel. The traveling chassis has the ground profiling and chassis vibration damping functions, and comfort and stability of the grain combine harvester in the field working process are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of a chassis frame of a grain combine harvester, and in particular relates to a profiling vibration-absorbing crawler-type walking chassis of a grain combine harvester, which can be widely used for smooth walking on various types of uneven ground and field work. grain harvest. Background technique [0002] The crawler chassis is the basic platform for agricultural machinery field operations, and its performance directly determines the working capacity of the whole machine. The crawler chassis in agricultural machinery is rarely used in foreign dry land operations, and it is more commonly used in wet and soft field grain harvesting in my country . When my country's grain combine harvester works in the field, its walking conditions are complicated and the field ground is uneven. When the combine harvester works in the field, it is very common to cross ridges, go up and down slopes, an...

Problems solved by technology

[0004] Aiming at the problems existing in the existing technology of my country's medium-sized crawler-type grain combine harvester due to the large body, the heavy weight of the whole machine when the granary is full, and the long track length, etc. In order to avoid the risk of overturning, as well as the severe bumping and violent vibration of the whole machine on hard uneven roads and continuous obstacles, the invention provides a profiling vibration-absorbing crawler-type walking chassis of a grain combine harvester. The two-level vibration-absorbing crawler-type walking chassis with ground profiling and anti-vibration functions reduces the vertical vibration of the whole machine when it is working in the field, prevents the "nodding" and "backward" rollover danger of the whole machine when going up and downhill, and reduces the risk of overturning in the field. The bumps when the hard ground crosses the ridge improves the stability of the whole machine when climbing and crossing the ridge in the field
