Lower frame structure of crawler-type cane harvester

Abstract

The utility model discloses a lower frame structure of a crawler-type sugarcane harvester, which aims to solve the problems that a crawler belt is easy to separate from a guide wheel and sugarcane heads left on sugarcane ridges are easy to knock over in the conventional crawler-type sugarcane harvester. The lower frame structure is characterized in that one end of an extension frame (2) is arranged on each of two sides of a lower frame (1); and a walking box connecting plate (3) is fixed at the other end of the extension frame (2), so that the lower frame (1), the extension frame (2) and the walking box connecting plate (3) form an inverted U shape. Therefore, the sugarcane harvester has the advantages of being capable of working on sugarcane ridges with different widths, not prone to disengagement of the crawler belt from the guide wheels and capable of improving trafficability.

Description

Technical Field

[0001] The utility model relates to a crawler type sugarcane harvester, in particular to a lower frame structure of the crawler type sugarcane harvester. Background Art

[0002] At present, a crawler type sugarcane harvester is disclosed on the market, which has the following structural features: it consists of an upper frame structure, a power assembly, an extension arm, a hydraulic assembly, a radiator, a fuel tank and a cab. A turntable is provided on the upper frame structure, which is rotatably connected to the lower frame. The cab is arranged at the left front end of the upper frame structure, one end of the extension arm is mounted in the middle of the front end of the upper frame structure, the power assembly and the radiator are arranged in the middle of the rear end of the upper frame structure, and two fuel tanks are respectively mounted on the left and right sides of the rear end of the upper frame structure. Crawler walking mechanisms are provided on both sides of the lower frame, and rotating claws for grabbing sugarcane are mounted on the other ends of the extension arm. Since the width of sugarcane ridges varies from place to place, and the distance between the crawlers on both sides of the structure is fixed, when the crawlers enter the ditch, because the land on both sides of the sugarcane ridge is sloped, the crawlers are likely to detach from the guide wheels, affecting the tillage efficiency. Moreover, since the height of sugarcane ridges varies from place to place, when the structure enters the ditch, it is likely to knock down the sugarcane heads left on the sugarcane ridge, thereby affecting the growth of sugarcane in the next season. Summary of the Invention

[0003] The utility model aims to provide a crawler type sugarcane harvester lower frame structure which can operate on sugarcane ridges of different widths, is not easy to make the crawler track separate from the guide wheel, ensures the farming efficiency, and improves the passability to ensure the growth of sugarcane in the next season.

[0004] To achieve the above-mentioned purpose, the utility model provides a crawler sugarcane harvester lower frame structure, including an underframe, one end of an extension frame is respectively provided on both sides of the underframe, and a traveling box connecting plate is fixed to the other end of the extension frame, so that the underframe, the extension frame and the traveling box connecting plate form an inverted U shape.

[0005] Four walking box connecting plates are provided at the other end of the extension frame, two walking box connecting plates are installed at a specified interval on the outside of the other end of the extension frame, and two walking box connecting plates are installed at a specified interval on the inside of the other end of the extension frame, so that the walking box and the crawler track can be placed between the two walking box connecting plates on the inside of the other end of the extension frame and the two walking box connecting plates on the outside of the other end of the extension frame.

[0006] Two traveling box connecting plates connected to the outer side of the other end of the extending frame are respectively connected to the extending frame and the traveling box through bolts.

[0007] The upper ends of the two traveling box connecting plates connected to the inner side of the other end of the extension frame are fixedly connected to the extension frame, and the lower ends of the two traveling box connecting plates connected to the inner side of the other end of the extension frame are connected to the traveling box through bolts.

[0008] With this structure, the lower frame, extension frames, and track connecting plates are attached to the other ends of the extension frames, forming an inverted U-shape. This improves maneuverability. Furthermore, because the track and crawler tracks are positioned between the two track connecting plates on the inside and outside ends of the extension frames, the machine can operate on sugarcane ridges of varying widths without causing the crawler tracks to detach from the guide wheels, ensuring efficient cultivation.
