[0002] Straw mulching is a conservation tillage model that can effectively utilize straw and is convenient and fast. In my country, especially in the Northeast, in order to respond to the government's policy of banning straw burning and strengthening the protection of black soil, the straw mulching model can efficiently utilize the straw left after crop harvesting, while also playing a role in water conservation, cost saving, efficiency improvement, and soil and water loss prevention.

[0003] According to the description in the pre-tillage straw combing device for rotary tillers disclosed on the patent website (authorization announcement number: CN 211792732 U), "The utility model provides a pre-tillage straw combing device for rotary tillers, in the technical field of agricultural machinery rotary tillers and straw return to the field. It includes an auger left support, an auger right support and an auger connected to the frame assembly of the rotary tiller; the auger includes an auger shaft and auger blades, and a spiral auger blade is fixed on the auger shaft; the auger shaft is rotatably connected to the left and right supports of the auger; the auger shaft is connected to the driving device; the auger blades include left-rotating auger blades and right-rotating auger blades, and the auger rotates to comb the straw on the ground to both sides or the middle, and comb the straw from the plot that needs rotary tillage to the plot that needs straw covering and returning to the field. The utility model mainly solves the problem that traditional rotary tillers are not suitable for the straw covering and returning to the field tillage mode, while improving the quality of rotary tillage, enhancing the straw covering and returning to the field effect, and also has the characteristics of simple and reliable structure, low cost, energy saving and easy use."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the auger blades rotate around the auger shaft, and the blades can exert a uniform and uninterrupted horizontal force on the straw, so that the straw can be effectively moved in the desired direction to achieve the purpose of combing (or sorting) the straw. In actual use, since the installation position of the auger blades of the device is fixed, it cannot be well adjusted according to the straw position and the subsequent classification position, resulting in certain limitations in use. At the same time, the device uses a sprocket for power transmission, which causes the chain of the device to loosen or slip when the field is uneven. Therefore, it is necessary to improve a straw combing device before tilling an agricultural rotary tiller to solve the above problems. Utility Model Content
