Chassis frame for combine harvester and combine harvester with same

Abstract

The invention discloses a chassis frame for a combine harvester. The chassis frame comprises a plurality of beams, plates and supporting seats, wherein the connection of the beams, plates and supporting seats comprises bayonet connection. The chassis frame comprises an upper frame right longitudinal beam, an upper frame left longitudinal beam, an upper frame left-middle longitudinal beam, a right support framework beam, a left support framework beam, an upper frame front short beam, an upper frame front cross beam, an upper frame front-middle cross beam, an upper frame rear-middle cross beam, an upper frame rear cross beam, an upper frame tail cross beam, a water tank supporting seat, a supporting seat plate, a long supporting seat, a short supporting seat, an annular part and the like. According to the chassis frame disclosed by the invention, the integrality is high, the bearing strength is greatly improved and the arrangement of upper-layer parts is facilitated; compared with the traditional frame, the chassis frame disclosed by the invention has the advantage that the welding process is simpler; the water tank supporting seat is arranged for facilitating the bearing of an enlarged water tank; the supporting seat plate can achieve dual purposes; the annular part can allow the hydraulic oil pipe at the front part of the harvester to pass fluently; bayonets formed in part of cross beams facilitate the positioning and welding process; positioning pins facilitate the assembly.

Description

technical field [0001] The invention relates to a chassis frame of a combine harvester, in particular to a combine harvester chassis frame arranged in a checkerboard structure and a combine harvester using the chassis frame. Background technique [0002] With the progress of society and the development of science and technology, more and more machinery and equipment are applied to agricultural production, and the combine harvester is one of them. The combine harvester can complete the harvesting, threshing, separating the stems, removing debris and other processes of cereal crops at one time, and directly obtain various corresponding finished or semi-finished crops from the field. [0003] Combine harvesters are divided into self-propelled combine harvesters and towed combine harvesters. Among them, self-propelled combine harvesters are easy to use and have good adaptability, which is the main development direction of combine harvesters. The self-propelled combine harvester...

AI Technical Summary

Problems solved by technology

Because the working intensity of the combine harvester is usually high, the force on the chassis frame is also relatively large. The existing connection method of the chassis frame usually adopts collision welding, which has poor chassis integrity, difficult positioning, troublesome welding process, and high strength. Not big enough for the practical needs of the combine harvester
