Beet vine cutting machine

Abstract

The invention relates to agricultural machinery, in particular to a beet vine cutting machine. The beet vine cutting machine comprises a frame, a main drive shaft, a shock absorbing device, top cutting devices and rotary leaf removal devices, wherein the main drive shaft, the shock absorbing device, the top cutting devices and the rotary leaf removal devices are all arranged on the frame, the rotary leaf removal devices are respectively arranged below the front parts of both sides of the frame, the shock absorbing device and the top cutting devices are located at the rear of the frame, the topcutting devices are respectively arranged at the rear parts of both sides of the frame, the shock absorbing device is located above the top cutting devices, the cutting devices are connected with theframe through the shock absorbing device, and the main drive shaft is respectively connected with the top cutting devices and the rotary leaf removal devices. The beet vine cutting machine adopts a twisting and thrashing principle, integrates vine cutting and stem removal processes by means of a twisting vine cutting mechanism, simplifies the structure and reduces the power consumption. By meansof a crawling cutting method, a crawling cutting mechanism is used for completing the cutting of beet green heads and adapting to the growth of beets at different heights and spacings.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a beet seedling killing machine. Background technique [0002] China is the eighth largest sugar beet planting country in the world. The planting areas are concentrated in more than ten provinces in the Northeast, Northwest and North China north of 40° north latitude. Among them, Xinjiang, Inner Mongolia and Heilongjiang are the three main producing areas, accounting for 90.3% of the country's planting area. %~95.8%. Sugar beet is an important raw material for my country's sugar industry, with an annual crushing capacity of 7 million tons and an increasing trend year by year. The development of sugar beet topping is of great significance for reducing farmers' labor, increasing production and improving work efficiency. [0003] The high nitrogen content in beet green tops hinders the sugar refining process. If the amount of beet green tops is cut too much during harvesting, the yield wil...

AI Technical Summary

Problems solved by technology

The top cutting machine is a high-speed rotation of multiple rollers, which consumes a lot of power, has a large structure size, and is heavy. Even the cutter is blocked, which affects the effect of cutting green heads, and requires manual secondary cutting, which wastes a lot of labor

At the same time, most of the topping knives are directly fixedly connected to the frame, which cannot achieve effective profiling, and the size of the beets cannot be effectively distinguished during the topping process, which leads to insufficient topping of some larger beets and insufficient topping of small beets. Excessive, prone to omissions, over-cutting, etc., so that the utilization rate of sugar beets decreased, increased labor costs, resulting in a lot of unnecessary waste
