Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a straw cutting and collecting machine. Background Art

[0002] In recent years, with the increase in corn harvesting rates, straw has been scattered in the fields as waste. The length of the straw mostly ranges from 5 cm to 20 cm, which brings great trouble to the recycling and reuse of the straw.

[0003] Today's straw pickers are usually located behind a tractor, with the tractor moving in front and the picker behind. When working in a corn field with relatively high temperature, the two rows of corn stalks stepped on by the tractor's tires are pressed to the ground, making it impossible for the picking device at the back to pick up the stalks, affecting the practicability of the machine. In addition, the picked-up straw is directly transferred to the storage vehicle carried by the tractor after being crushed, and workers are required to pack and separate them, which is inefficient. Utility Model Content
