1. Product Name: Kaixuan Wang Straw Grinding and Returning Machine

2. Product model: 1JHY-120

3. Manufacturer: Hebei Gengmu Agricultural Machinery Manufacturing Co., Ltd

4. Product Introduction: The series of straw crushing and returning machines produced by Hebei Gengnong Agricultural Machinery Manufacturing Co., Ltd. have good crushing quality, high operating efficiency, and all performance indicators meet or exceed the requirements of relevant national standards. The model can be matched with tractors ranging from 15 to 95 kW (2 to 130 horsepower), with full suspension operation. It has good shredding and crushing performance for corn, sorghum, cotton, rice and other straw that is upright or laid in the field, making it an ideal tool for straw shredding and returning to the field.

5. Scope of application: This machine is suitable for crushing and returning straw from crops such as corn, cotton, wheat, rice, pineapple, etc. It can also improve soil structure and enhance soil fertility. Moreover, it can compete for agricultural time, reduce labor intensity, and avoid environmental pollution caused by burning straw.

6. Product structure and working principle: The main structure of the straw chopper and returning machine consists of a suspension device, gearbox, transmission mechanism, cover, blade shaft, and ground wheel. When working, the power output shaft of the tractor is transmitted to the gearbox through a universal joint. Through the speed increase of the transmission mechanism, the blades on the blade shaft rotate at high speed, generating high acceleration. The straw is cut and driven into the casing, and together with the fixed blade, it is repeatedly hit, torn, and kneaded until the straw is crushed. Under the action of airflow and centrifugal force, broken straw is evenly scattered along the inner wall of the cover on the ground behind.
