[0002] Cabbage is one of the main varieties of vegetable cultivation, but compared with grain production, the mechanization level of vegetable production is relatively backward. For a long time, the harvest of cabbage still relies mainly on manual labor, which has low labor efficiency, high labor intensity, poor operation quality and high production cost.
[0003] Our company's Chinese utility model patent number is CN2022208712019, which includes a header device, a power chassis and a cabbage transmission mechanism, and the gasoline engine provides power for the whole machine. The header device is located at the front end of the frame, the cabbage transmission mechanism is located in the middle of the frame, and the gasoline engine, the shift control box and the hand-held handle are located at the rear of the frame. The header device is modularly mounted on the front end of the frame as a whole, and can be controlled by a single button of the oil cylinder to flip and lift the header device relative to the frame; the tension wheel is designed to be movable in front and is kept on the same ground plane as the load-bearing wheel, which extends the contact area between the crawler and the ground, making the walking more stable and reliable; the whole machine is driven by a gasoline engine, and the walking adopts a hand-held integrated design. The whole machine has a compact structure, is small and light, has low cost and is easy to use.
[0004] However, there is a defect in the use process: the harvested cabbage cannot be leafed, and farmers need to pluck the cabbage again, which increases labor costs and wastes time.
[0005] To this end, the utility model provides a transmission mechanism suitable for a hand-held cabbage harvester, which can harvest the cabbage and remove leaves at the same time. Summary of the invention
[0006] The technical problem to be solved by the utility model is to provide a transmission mechanism of a hand-held cabbage harvester in view of the deficiencies of the prior art.
[0007] The technical solution of the utility model is that it includes a transmission main shaft 3 and a pulley 2, a driving sprocket 1 and a driving sprocket 2 4 arranged on the transmission main shaft 3, the pulley 2 is connected to the engine through a belt, and the driving sprocket 1 is connected to the cutting table assembly through a sprocket, and is characterized in that: a driving tooth chain welded body 5 and a passive tooth chain welded body 10 are provided below the driving sprocket 2 4, and the passive tooth chain welded body 10 is connected to a right angle conversion box 3 9 through a shaft, the right angle conversion box 3 9 transmits power to the right angle conversion box 2 8 through a universal coupling 6, and then transmits power to the right angle conversion box 1 7 arranged above the right angle conversion box 2 8 through a shaft, and the right angle conversion box 2 8 and the right angle conversion box 1 7 are respectively connected to the transverse conveyor belt and the blade roller through sprockets / shafts.
[0008] The active tooth chain welded body 5 is welded by a sprocket and a gear 1 5 - 1 , and the passive tooth chain welded body 10 is also welded by a sprocket and a gear 2 10 - 1 . The gear 1 5 - 1 and the gear 2 10 - 1 have the same module and mesh with each other.
[0009] The active sprocket 2 4 is connected to the sprocket on the active toothed chain welding body 5 through a chain and transmits power to the gear 2 10-1 through the gear 1 5-1, so that the passive toothed chain welding body 10 rotates. The passive toothed chain welding body 10 divides the power into two. The passive toothed chain welding body 10 drives the right-angle conversion box 3 9 to work through the shaft. At the same time, the sprocket on the passive toothed chain welding body 10 drives the longitudinal conveyor belt to work through the chain.
[0010] Compared with the prior art, the utility model has the following advantages: first, the transmission mechanism is ingenious, and power can be transmitted to all working assemblies of the cabbage harvester through the engine; second, the structure is compact, which improves the space utilization rate of the whole machine.
