TECHNICAL FIELD
[0001] The utility model relates to a straw returning to field stubble cleaning machine belongs to agricultural machinery field. BACKGROUND
[0002] Straw returning to field stubble is an ecological management technique in agricultural production, mainly applied to straw treatment after crop harvesting. It promotes the improvement of soil fertility and improves soil structure by directly returning crop straw to the field combined with appropriate stubble cleaning measures, while reducing the environmental burden of agricultural waste. The commonly used straw pulverizer is to use high-speed rotation to achieve the purpose of pulverization. In the use process, the oil silk rope elastic ruler is installed. When encountering wetland corn straw, the lifting of the oil silk rope elastic ruler to the straw is not very good, and the oil silk rope elastic ruler is also prone to deformation. When the amount of corn straw is large, it is easy to block and cause the pile to be removed, affecting the stubble cleaning effect. Moreover, the supporting power is large, the oil consumption is high, the straw in the ridge ditch cannot be picked up, thereby the effect is not ideal, and the next operation link operation is affected.
[0003] Therefore, it is urgent to propose a new type of straw returning to field stubble cleaning machine to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0010] This utility model has the following beneficial effects:
[0011] 1. Compared with the traditional blade and hammer system, the spring tooth turntable of this utility model has stronger adaptability. Especially when processing different types of straw, it can better prevent straw, vines and other weed stubble from getting tangled on the machine parts, reducing equipment failure and downtime. Whether it is soft rice straw or hard corn straw, the spring tooth turntable can effectively handle it, reducing the problem of unstable operation caused by different types of straw.
[0012] 2. The spring teeth on the spring tooth turntable of this utility model can powerfully tear and shear the straw through high-speed rotation, thereby breaking the straw into smaller fragments, which are easier to return to the field;
[0013] 3. The elastic properties of the toothed turntable of this utility model make it less likely for straw to get stuck or cause machine blockage when it is torn by the toothed rack, thus improving the continuity and efficiency of operation.
[0014] 4. This utility model uses the crushing action of the toothed turntable to cut the straw into smaller particles, increasing the contact area between the straw and the soil. At the same time, the toothed turntable does not require additional driving power; it can rotate simply by the friction between the teeth and the ground when walking, thus reducing fuel consumption and saving energy and reducing emissions.
[0015] 5. The straw returning and stubble-killing machine of this utility model has a simple structure, ingenious design, convenient disassembly and assembly, and is sturdy, making it suitable for widespread use. Attached Figure Description
