Description

Technical Field

[0001] This utility model relates to vegetable harvesters in agricultural machinery, specifically a chassis for a self-propelled electric cabbage harvester. Background Technology

[0002] Cabbage is one of the main vegetable varieties, but compared with grain production, the level of mechanization in vegetable production is relatively backward. For a long time, cabbage harvesting has still relied mainly on manual labor, which is characterized by low labor efficiency, high labor intensity, poor work quality, and high production costs.

[0003] Our company's Chinese utility model patent, CN202220871201.9, includes a header device, a power chassis, and a cabbage conveying mechanism, powered by a gasoline engine. The header device is located at the front of the frame, the cabbage conveying mechanism is located in the middle of the frame, and the gasoline engine, gear shift control box, and handrail are located at the rear of the frame. The header device is modularly and integrally attached to the front of the frame, and can be tilted and raised relative to the frame via a single button control using a hydraulic cylinder. The tension wheel has a front-mounted movable design and is kept on the same ground plane as the load-bearing wheel, extending the contact area between the tracks and the ground, resulting in smoother and more reliable movement. The entire machine is driven by a single gasoline engine, and the walking mechanism uses an integrated handrail design, making the overall structure compact, lightweight, low-cost, and easy to use.

[0004] However, it has the following drawbacks during use: First, the gasoline engine is quite noisy and produces exhaust pollution; second, it cannot turn around on the spot; and third, it cannot achieve automated and unmanned operation.

[0005] Therefore, this utility model provides a self-propelled electric cabbage harvester chassis that can reduce pollution and noise. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a self-propelled electric cabbage harvester chassis, addressing the shortcomings of the existing technology.

[0007] The technical solution of this utility model is: a self-propelled electric cabbage harvester chassis, including a chassis support 11 and a frame 4 fixed on top. The front end of the chassis support 11 is provided with a tension wheel 2, and the bottom is provided with more than 4 evenly distributed load-bearing wheels 14. The front end of the frame 4 is welded with a cutting table support 3, and the rear end is provided with a handle 6. The characteristic is that: the frame 4 is also provided with a ramp 12 in the middle, the top of the ramp 12 is a battery mounting box 15, and the rear of the battery mounting box 15 is provided with an electric control panel 7; the battery mounting box 15 is provided with a walking motor 10 and a planetary gear reducer 17 below it. The output end of the planetary gear reducer 17 is connected to a drive wheel 18, and the drive wheel 18 is fixed to the bottom of the end of the frame 4 through a bearing seat 16.

[0008] A transverse conveyor belt support 15 is provided in front of the ramp 12, a collection basket support 8 is welded to the rear side of the frame 4, and a longitudinal conveyor belt support 9 is welded to the front end of the collection basket support 8.

[0009] A transmission bracket 1 is welded below the front end cutter support 3 of the frame 4.

[0010] The planetary gear reducer 17 is a right-angle bend reduction gearbox.

[0011] The advantages of this utility model compared with the prior art are: first, the noise is reduced by driving the cabbage chassis with a motor; second, the dual-motor driven chassis can turn around on the spot; and third, it can work with the Beidou navigation system to achieve unmanned and automated operation.
