Description

Technical Field

[0001] This utility model relates to vegetable harvesters in agricultural machinery, specifically 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 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, which addresses the shortcomings of the existing technology.

[0007] The technical solution of this utility model is: a self-propelled electric cabbage harvester, including an electric chassis 19 located below, a frame 5, and a header assembly 2 supported at the front end of the frame 5. The frame 5 is provided with a transverse conveying mechanism 14 and a longitudinal conveying mechanism 10. The transverse conveying mechanism 14 is located directly behind the header assembly 2 and has a leaf-removing roller 15 above it. The longitudinal conveying mechanism 10 is located on the outer side of the frame 5 and behind the transverse conveying mechanism 14. The characteristic is that the header assembly 2, the transverse conveying mechanism 14, the longitudinal conveying mechanism 10, and the leaf-removing roller 15 are all driven individually by a working motor 6 through a transmission mechanism. A battery and electronic control system 7 and an electronic control operating table 8 are arranged sequentially at the rear of the frame 5. The electric chassis 19 is provided with symmetrically arranged walking motors 22 located below the battery and electronic control system 7, and the walking motors 22 are connected to drive wheels 23 and fixed to the bottom of the frame 5 by bearings.

[0008] The transmission mechanism includes an intermediate shaft 1, three right-angle conversion boxes 9 arranged from top to bottom in front of the transverse conveying mechanism 14, and a right-angle conversion box 9 fixed inside the longitudinal conveying mechanism 10. The intermediate shaft 1 is provided with a cutting table sprocket 3, a pulley 4, and a double sprocket 16 in sequence. The cutting table sprocket 3 is connected to the sprocket on the cutting table assembly 2 via a chain. The pulley 4 is connected to the working motor 6 via a belt. The double sprocket 16 is connected to the driven sprocket 17 and the driven sprocket 2 18 via a chain. The driven sprocket 2 18 is connected to the conveying leaf 13 above the transverse conveying mechanism 14. The driven sprocket 17 is connected to the right-angle conversion box 9 at the top front of the transverse conveying mechanism 14, which transmits power to the two right-angle conversion boxes 9 below in sequence. The middle right-angle conversion box 9 is connected to the leaf roller 15, and the bottom right-angle conversion box 9 is connected to the transition shaft 24.

[0009] The transition shaft 24 passes through the transverse conveying mechanism 14. The front end of the transition shaft 24 is provided with a passive sprocket 21, and the end is connected to the right-angle conversion box 9 inside the longitudinal conveying mechanism 10 through a universal coupling 12.

[0010] The passive sprocket 21 is connected to the sprocket 20 of the transverse conveyor mechanism via a chain.

[0011] The longitudinal conveying mechanism 10 is provided with a longitudinal conveyor belt mechanism support 11 below it, which is welded to the frame 5. A collection basket is placed at the tail end of the longitudinal conveyor belt mechanism support 11.

[0012] Compared with the prior art, this utility model has the following advantages: First, the cabbage chassis is driven by a motor to move and work, which reduces noise and pollution; 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.
