Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0028] The sugar beet seedling-killing and top-cutting machine comprises a frame 1, on which a transmission mechanism, a ground wheel guide mechanism, a seedling-killing mechanism and a top-cutting mechanism are arranged. The ground wheel guide mechanism includes ground wheels 18 positioned at both sides of the frame 1, and the ground wheels 18 are installed on the connecting rod 10 as the running mechanism of the whole machine.
[0029] The transmission mechanism is connected to the power source of the top cutting machine, including a gear box 5, and the power output shaft 4 of the gear box 5 is connected with a sprocket 2, and the sprocket 2 is provided with a transmission chain 3, which is connected to the power input of the rice seedling killing mechanism through the transmission chain 3 The shaft provides power for the rice seedling killing mechanism.

The invention relates to a beet stem chopping and topping machine. Each stem chopping mechanism comprises two wheel discs and stem chopping tools distributed spirally along the surface of the wheel discs, each stem chopping tool is mounted on the wheel discs through swing arms at two ends of the corresponding blade, and the swing arms are hinged to the wheel discs and capable of rotating around corresponding joints to realize flexible stem chopping. Each topping mechanism comprises a cutter mechanism and a profiling linkage mechanism, a cutter of each cutter mechanism is arc shaped, two sides of each cutter are connected with a cutter holder through a mounting shaft, and each cutter is capable of rotating around the corresponding mounting shaft. Each profiling linkage mechanism enables the corresponding cutter to be adjustable in position according to landforms, so that uniformity in topping thickness can be achieved. By combination of the topping mechanisms and the profiling mechanisms, vibration resetting of the cutters is realized after cutting is finished, and consequently attachments on the cutters can be removed. Owing to the swing arms, flexible contact between the stem chopping tools and beets is realized, and the beets are protected from being damaged by the stem chopping mechanisms. Since traditional fixed cutters are structurally replaced by the cutters capable of rotating around the shafts, topping can be realized more easily, beet roots are protected from being pushed down, blockage of the cutters is avoided, topping efficiency is improved, and the beet stem chopping and topping machine is suitable for high-speed operations.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to an agricultural harvesting machine, in particular to a top cutter used for harvesting sugar beets and similar crops. Background technique [0002] Seedling and top cutting operations are an important link in the crop harvesting process, which is labor-intensive and inefficient. The seedling cutting and top cutting machine is used for harvesting operations, for cleaning crop seedlings and top cutting operations, which can effectively improve the harvesting efficiency of crops, so that crops can be harvested in time. Realize the modernization of crop production, save labor and reduce labor intensity, and liberate people from heavy production labor. [0003] Present most seedling killing mechanism adopts the cutter roller that is fixed on the seedling killing mechanism to shake and pulverize sugar beet seedling leaves. This kind of mechanism can remove the seedling le...
