Abstract
The utility model relates to a track straining device on cabbage harvester power chassis, including chassis frame (4) and locate take-up pulley (1), bearing wheel (3), drive wheel (5) and track (2) on chassis frame (4), chassis frame (4) are by the integral type frame construction that square tube welding formed. The tensioning wheel bracket (6) is of a Y-shaped structure, and a bent structure is arranged between the front fork-shaped structure and the rear horizontal rod; the tension wheel (1) is supported on a fork-shaped structure at the front end of a tension wheel support (6), and a horizontal rod at the rear end is directly arranged in a square tube of the chassis frame (4) and can horizontally move in the square tube. The obtuse angle beta of the bending shape is 130-140 degrees. The movable type crawler belt has the advantages that the front-mounted movable type design of the tensioning wheel enables the tensioning wheel and the bearing wheel to be kept on the same horizontal plane, the contact area of the crawler belt and the ground is increased, and walking is more stable and reliable.
Description
Technical Field
The utility model relates to an agricultural machine, especially a track straining device on cabbage harvester power chassis.
Background
Cabbage is one of the main varieties for vegetable planting, but the mechanization level of vegetable production is relatively laggard compared with grain production. For a long time, the harvesting of the cabbages still basically depends on manual operation, and has low labor efficiency, high labor intensity, poor operation quality and high production cost.
For this reason, some cabbage harvesting mechanisms have been newly developed in recent years, and the latest harvester is mainly of a large riding structure, such as the disclosed "cabbage harvester" (patent No. 2021101436874), in which the power chassis of the traveling mechanism is composed of a chassis assembly and two track assemblies. The tensioning wheel is of a fixed type non-adjustable structure, and the contact area between the crawler and the ground cannot be increased to the maximum extent, so that the walking stability is improved.
Disclosure of Invention
The utility model aims to solve the problem that the crawler-type power chassis of a cabbage harvester is provided to the not enough of last prior art. The chassis frame structural design as an organic whole, take-up pulley activity sets up, and can furthest's increase the area of contact on track and ground, improves the stability of walking.
The technical scheme of the utility model is, including chassis frame (4) and locate take-up pulley (1), bearing wheel (3), drive wheel (5) and track (2) on chassis frame (4), chassis frame (4) are the integral type frame construction that forms by square tube welding, and take-up pulley (1) supports the front end in chassis frame (4) through take-up pulley support (6) forward type, its characterized in that: the tensioning wheel bracket (6) is of a Y-shaped structure, and a fork-shaped structure at the front end of the tensioning wheel bracket is bent with a horizontal rod at the rear end of the tensioning wheel bracket; the tensioning wheel (1) is supported on a fork-shaped structure at the front end of the tensioning wheel support (6), and a horizontal rod at the rear end of the tensioning wheel support (6) is arranged in a square tube of the chassis frame (4) and can horizontally move in the square tube of the chassis frame (4). Obtuse angle beta
The bent shape between the front fork-shaped structure of the Y-shaped tension wheel bracket (6) and the rear horizontal rod is an obtuse angle beta which is 130-140 degrees.
The tensioning wheel (1) and the bearing wheel (3) are on the same plane with the tangent line of the ground.
The utility model discloses with the advantage that prior art relative ratio possessed, the take-up pulley adopts leading movable design, and the take-up pulley support is "Y" shape design of bending, makes the take-up pulley keep simultaneously with the bearing wheel all the time with ground contact on same horizon to the area of contact on track and ground has been prolonged, makes the walking more steady reliable.

fig. 2 is a schematic structural diagram of the tension pulley 1, the tension pulley bracket 6 and the chassis frame 4 in fig. 1.
Reference numbers in the figures: 1-a tension wheel, 2-a track, 3-a bearing wheel, 4-a chassis frame, 5-a driving wheel, 6-a tension wheel bracket and a beta-obtuse angle.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The utility model relates to a track straining device on cabbage harvester power chassis, including chassis frame (4) and locate take-up pulley (1), bearing wheel (3), drive wheel (5) and track (2) on chassis frame (4), chassis frame (4) are the integral frame construction that forms by square pipe welding, and take-up pulley (1) is through the front-end of take-up pulley support (6) forward type support in chassis frame (4).
The tensioning wheel support (6) is of a Y-shaped structure, and a fork-shaped structure at the front end of the tensioning wheel support and a horizontal rod at the rear end of the tensioning wheel support are arranged in a bent mode. The tensioning wheel (1) is supported on a fork-shaped structure at the front end of the tensioning wheel support (6), and a horizontal rod at the rear end of the tensioning wheel support (6) is arranged in a square tube of the chassis frame (4) and can horizontally move in the square tube of the chassis frame (4).
The bent shape between the front fork-shaped structure of the Y-shaped tension wheel bracket (6) and the rear horizontal rod is an obtuse angle beta which is 130-140 degrees.
The tensioning wheel (1) and the bearing wheel (3) are on the same plane with the tangent line of the ground.
The obtuse angle beta of the bending of the tensioning wheel bracket (6) is 135 degrees in the embodiment. After the horizontal end of the tension wheel support (6) is properly adjusted in the square tube of the chassis frame (4), the tension wheel support (6) can be fixed through a stop bolt or a direct welding mode.
