The Development of Commercial Leaf and Branch Shredding Machine

Abstract

In this research, the commercial leaf and branch shredding machine was developed. The research was mutually conducted with Harvester Sales and Service (Thailand) Company Limited (the co-researcher) with the office located in Phrae Province. The leaf and branch shredding machine was focused on its usages, performance and efficiency. For the processing, machined was manufactured by casting flat brace for using with 6308 bearing which exhibits high strength property and could resist the compression. Besides, 6308 bearing was also easier to manufacture which consumed less time production. The samples were prepared using turning, shaving, etching and joining, respectively.
For development of commercial leaf and branch shredding machine, the entrepreneur’s objection was system improvement by using generator which could generate electric current of 1,500 rounds per minute and electric potential of 220 volts. Both of current and potential were controlled via controlled box which could measure an occur quantity of electric.  After the determination, it was found that the machine showed good results for mincing woods which could observe from the samples with diameter of 2-4 cm, 4.6 cm and more than 6 cm, respectively.  Furthermore, the machine was examined with fresh and dry branches and it had been seen that the nearly closed average size of branched after shredding was 1.91 cm and 1.90 cm for fresh and dry branched, respectively.
In addition, the research group had distributed and instructed about shredding machine to the entrepreneur and cooperated to create the new market in 2 areas. Firstly, distribution the commercial leads and branch shredding technology to Hat Kruat Subdistrict Munipatual, Hat Kruat Subdistrict, Muang District, Uttaradit. The total average value was 4.32. Secondly, distribution the commercial leads and branch shredding technology to to Nam Rid Subdistrict Munipatual, Nam Rid Subdistrict, Muang District, Uttaradit. The total average value was 4.06. From the obtained evaluation values, it could be said that the research was accomplished and achieve the objectives.
