Description

Beet seedling killing machine

Technical Field

The utility model relates to the field of agricultural machinery, in particular to a beet seedling killing machine.

Background

The beet is the second important sugar source of sugarcane in sugar industry, and the sugar content of beet is mainly distributed on root tuber, so the harvesting operation steps of beet are mainly divided into seedling killing, pulling up and transporting, i.e. before harvesting the root tuber of beet, the stem and leaf on the root tuber of beet are removed by seedling killing machine, then the root tuber of beet is pulled up and transported away. As the green tops of the beet tuberous roots exposed out of the soil contain more nitrogen elements and can have harmful effects on the sugar making process, the green tops of the tuberous roots can be cut off together when the beet is subjected to seedling killing operation. Therefore, seedling killing and top cutting are an essential process in beet harvest.

According to the growth conditions of beets, generally, the beets with large root tubers are exposed out of the soil in a large amount, the green tops on the tops of the root tubers are also larger, the beets with small root tubers are exposed out of the soil in a small amount, and the green tops on the tops of the root tubers are also smaller. However, the spacing between the copying device and the top cutter of the top cutting component of the existing beet seedling killing machine is fixed, or the spacing between the copying device and the top cutter can only be roughly adjusted according to the growth condition of the beet before the seedling killing machine operates. During the operation of the seedling killing machine, no matter how the size of the beet root tuber is, and the height of the green top exposed out of the soil is, the seedling killing machine only cuts off the root tuber top with the same height as the space between the profiling device and the top cutting knife. Therefore, the root tuber and the green top of the large beet cannot be completely cut off, the large beet still needs manual inspection and cutting off subsequently, working procedures are increased, manpower is wasted, and the yield of the small beet is influenced due to excessive cutting off of the root tuber and the green top of the small beet.

SUMMERY OF THE UTILITY MODEL
