It not only eliminates the air pollution caused by straw burning, but also has the effect of increasing fertilizer and yield. In the past, the common practice was to return the straw directly to the field after mechanical crushing. However, when returning the straw to the field in this way, insect eggs will be retained between the poles and will explode in the second year. In addition, the straw will rot in the field and consume nitrogen in the soil, causing soil fertility to decrease and affecting the normal growth of crops. Therefore, many people now use the method of composting the straw and returning it to the field as organic fertilizer.

[0003] After searching, the Chinese patent publication number CN208055227U discloses a harmless treatment device for organic fertilizer, including a treatment bin provided with an upper port, a cover body covering the upper port of the treatment bin and a stirring device extending into the treatment bin, the cover body is provided with an air outlet, the side wall of the treatment bin includes an inner wall and an outer wall, and a hollow structure is formed between the inner wall and the outer wall, the inner wall is provided with a plurality of through holes, the aperture of the through holes is smaller than the powder diameter of the organic fertilizer, and the lower end of the outer wall is provided with an oxygenation hole for filling oxygen into the hollow structure.

[0004] However, during composting and crushing, a large amount of connecting rods need to be processed. After sufficient crushing and stirring, the processed straw fragments need to be discharged to a suitable location for unified stacking. However, the above-mentioned technology lacks a device that can quickly discharge the straw after the crushing process is completed, resulting in the problem of limited connecting rod capacity that the device can process. For this reason, a device for harmless treatment of straw returning to the field is proposed. Utility Model Content

[0031] When the crushed straw falls into the mixing zone 4 for mixing and stirring, it is necessary to discharge the internally mixed and stirred straw and move it to the composting pool for processing, so that the device can continue to process the straw. At this time, the extrusion rod 25 moves downward to extrude the top rod 22 through the extrusion ramp 26. The extruded top rod 22 moves to one end and is inserted into the docking groove 18 at one end of the rotating stirring paddle 15. At this time, the discharging paddle 17 and the stirring paddle 15 can be driven to rotate together.
