Description

Technical Field

[0001] This utility model relates to vegetable harvesters in agricultural machinery, specifically a transmission mechanism for an 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 relatively noisy and produces exhaust pollution; second, it cannot achieve automated and unmanned operation.

[0005] Therefore, this utility model provides a transmission mechanism for an electric cabbage harvester, which can reduce pollution and noise. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a transmission mechanism for an electric cabbage harvester, addressing the shortcomings of the existing technology.

[0007] The technical solution of this utility model is: a transmission mechanism for an electric cabbage harvester, including a transverse conveying mechanism 3 located at the front and a longitudinal conveying mechanism 12 located on one side behind it. A leaf-removing roller 14 is provided above the side of the transverse conveying mechanism 3 close to the longitudinal conveying mechanism 12. The characteristic is that the transverse conveying mechanism 3, the longitudinal conveying mechanism 12 and the leaf-removing roller 14 are all powered by separate motors 9 and are transmitted separately through a transmission mechanism. The transmission mechanism includes a transition shaft 7, a right-angle gearbox 1 arranged from top to bottom at the front end of the transverse conveying mechanism 3 and a right-angle gearbox 1 fixed above the inner side of the longitudinal conveying mechanism 12. A header sprocket 5, a driven pulley 6 and a double sprocket 4 are arranged sequentially on the transition shaft 7. An active pulley 8 is provided on the motor 9 and transmits power to the driven pulley 6 through a belt to make the transition shaft 7 rotate. The transition shaft 7 then drives the header sprocket 5 and the double sprocket 4 to rotate. The header sprocket 5 is connected to the header assembly through a chain. The double sprocket 4 is connected to the driven sprocket 1 2 and the driven sprocket 2 10 through sprockets respectively.

[0008] The passive sprocket 1 2 is connected to the right-angle gearbox 1 at the top front end of the transverse conveyor 3, and the passive sprocket 2 10 is connected to the conveyor belt 11 above the transverse conveyor 3.

[0009] The right-angle gearbox 1 at the middle of the front end of the transverse conveying mechanism 3 is connected to the leaf-pulling roller 14, and the lowermost right-angle gearbox 1 is connected to the connecting shaft 17.

[0010] The connecting shaft 17 passes through the transverse conveying mechanism 3, and the front end of the connecting shaft 17 is provided with a passive sprocket 16, and the end is connected to the right-angle gearbox 1 on the inner side of the longitudinal conveying mechanism 12 through a universal coupling 13.

[0011] The passive sprocket 16 is connected to the transverse transmission sprocket 15 via a chain.

[0012] The advantages of this utility model compared with the prior art are: first, replacing the gasoline engine with an electric motor reduces noise and pollution, simplifies the transmission system, and improves transmission efficiency; second, it can be combined with remote control and Beidou navigation system to achieve unmanned and intelligent operation.
