The highly efficient multi-functional straw returning machine developed by Jiangsu passed the assessment

The Jiangsu Science and Technology Project “Research and Development of High-efficiency Multi-functional Straw Returning Technology and Machine Tools”, which is mainly participated by the Institute of Agricultural Mechanization of the Chinese Academy of Agricultural Sciences, recently held a live demonstration of equipment in Guanyun County, Lianyungang City. At the scene, the “1GJQN-165 Straw Crushing-Rotary Till Combination Multi-purpose Machine” successfully developed by the project was used to smash and smash the cotton straw. The results were recognized and praised by the leaders, experts and agricultural operators. Previously, the machine has successfully passed the test of Jiangsu Agricultural Machinery Test Station, and various technical indicators meet the design requirements.

The machine adopts the combination structure, which not only ensures the assembly is convenient, but also solves the problem of suspension and longitudinal stability of the unit; it ensures the multi-purpose of the machine, and can be used as the smashing machine and the rotary tiller separately according to the agronomic requirements. Can be combined into a multi-purpose machine, greatly improving its adaptability. The “two-way output straw crushing transmission box” in the machine can ensure reliable transmission of the supporting force of the machine and run smoothly; the grinding cutter shaft is symmetrically staggered, the cutter shaft is balanced by force, the machine runs smoothly and the vibration is small; Design a combined pulverizing knife or hammer to achieve interchangeability between the two to meet the needs of different work objects.

The field test results show that the machine can not only complete the smashing and reclaiming of the dwarf stalks such as rice and wheat, but also complete the smashing and returning of the stalks of corn, cotton and other high-stalk crops, and solve the environment caused by straw burning. Pollution problems and increased soil organic matter.

Round Molded Graphite

As the name implies, Round Molded Graphiteis a cylindrical product of graphite electrode, which is made of graphite block materials by crushing, screening, batching, shaping, cooling, roasting, dipping and graphitization of post section petroleum coke and medium temperature coal tar pitch. It has the advantages of high temperature resistance, corrosion resistance, good conductivity and light weight. It is mainly used for large DC resistance furnaces, blast furnace bricks, conductive electrodes, lining anti-corrosion and other purposes.

The high-purity graphite, graphite block and Molded Graphite produced by Pingdingshan Carbon Graphite Factory for many years are excellent, and the specifications of Round Molded Graphite are as follows: φ 450*800, φ 520*400 φ 630*420, φ 660*620 φ 780*600, φ 820*350~500 φ 900*350~400, φ 1050*350~400 φ 980~350*400, φ 1160*350~680 φ 1260*350~680, φ 1330*400 φ 1420*400, φ 1520*400 φ 1630*350, φ 1800*350 φ 2000*350, φ 520~2000*680
