 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Performance of a Self-propelled Riding Type Rice Transplanter) ผู้เขียน:นายกนกศักดิ์ เอี่ยมโอภาส, ผู้ช่วยศาสตราจารย์ , Vicha Munthumkarn, Narong Ounkong Yoshiaki Goto, Toshio Yamauchi สื่อสิ่งพิมพ์:pdf AbstractThe picking performance of a 4-row self-propelled riding type rice transplanter was evaluated in the experimental filds at Kasetsart University, Kampangsaen campus under two different field conditions. The first fields was prepared using a rotavator attached to the 22 kW four wheel tractor for both first plowing and puddling operation. The second field was plowed using a conventional moldboard plow and the puddling was done using a raker attached to the two wheel walking type tractor. Planting accuracy of the transplanter was measured in these filds. The missing hills and floating hills in the first field were measured to be 6.33% and 1.33% respectively with no observed buried hills. In the second field the missing hills and buried hills were measured to be 2.33% and 2.00% respectively with no observed floating hills. The soil mechanical properties affected the trans-planter performance were also measured and discussed. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : High Moisture Content Corn Sheller) ผู้เขียน:นายอัครเดช อรรถจินดา, รองศาสตราจารย์, Prayouth Suwanchiwakorn, Anek Sukchareon, Toshio Yamauchi สื่อสิ่งพิมพ์:pdf AbstractThe prototype of peg-tooth type corn sheller was designed and constructed based on the study of existing shellers locally manufactured. The purpose was to make it applicable to shelling ear corn with grain moisture content up to 28 percent, while the ordinary shellers were applicable to grain with moisture level of under 20 percent only. And at present, the prototype had already been finished but the testing procedure was still undergo. Spike tooth was used in the prototype after evaluation and analysis of the work done in the project and in the past. From the test and the study of its performance, the spike tooth gave rather low damage rate. In the test, it yielded under 6 percent grain damage at 27.8 percent grain moisture content, with unshelled rate lower than 1 percent. Suitable tip speeds of the drum that yielded lowest damage rate were about 5.5 to 6.0 meters per sec. For open-type and 5.0 to 5.5 meters per sec. for closed –type drum. Similar results were expected for the prototype. However, the design was made so that, if the round peg tooth gave somewhat different result, the other designed square type would be immediately replaced. |
