Abstract
The project entitled “modification and performance evaluation of self propelled reaper windrower for harvesting chickpea and wheat” was undertaken with the objectives to evaluate performance of self propelled vertical conveyor reaper for harvesting of chickpea and wheat crop and modifications done are development of collection and unloading unit. For collection of cut crop and heap making at every 5 m distance of travel. The testing was carried at Central Research Station of Dr.PDKV, Akola. Also the test results of mechanical harvesting of chickpea and wheat crop by self propelled vertical conveyor reaper were compared with test results of manual harvesting to know the benefits of mechanical harvesting over manual harvesting. The self propelled vertical conveyor reaper cut and windrowed cut crop uniformly in a row.
The average effective field capacity and field efficiency of the self propelled vertical conveyor reaper for chickpea was found to be 0.249 ha/h and 89.00 per cent, and for wheat it was 0.360 ha/h and 91.76 per cent respectively. Fuel consumption of self propelled vertical conveyor reaper was 0.725 lit/h and 2.84 lit/ha for chickpea and 0.700 lit/h and 1.92 lit/ha for wheat. The field trail of VCR has been conducted at different grain moisture content, in order to determine the optimum grain moisture content at which the harvesting losses are minimum. It was observed that at lower grain moisture content the per cent harvest losses were higher. At grain moisture content of 17.0 % the harvest losses were found minimum i.e. 2.33 % and in case of wheat at grain moisture content of 10.24% the harvest losse were found minimum i.e. 0.93 % as compared to the harvest losses at other higher grain moisture content.
The average harvesting losses for chickpea in mechanical harvesting and manual harvesting were found to be 8.01 per cent and 3.08 per cent, and for wheat crop 1.035 per cent and 1.83 per cent respectively. Developed collection and unloading unit was found work satisfactorily during laboratory and filler field trail. The cost of operation of self propelled vertical conveyor reaper and manual harvesting for chickpea were 850 Rs/ha and 1264 Rs/ha and for wheat 1155 Rs/ha and 3400 Rs/ha respectively. In mechanical harvesting the per cent saving in the cost of operation and time were found to be 32.83 per cent and 35.82 per cent and for wheat 66.02 per cent and 62.71 per cent respectively.
Description
The self-propelled vertical conveyor reaper is an engine operated, walk behind type reaper suitable for harvesting and windrowing cereals crops. During forward motion of the reaper, crop row dividers divide the crop, which come in contact with cutter bar, where shearing of crop stems takes place. The cut crop is conveyed to one side of the machine by the conveyor belt fitted with lugs and is windrowed in the field. The crop is collected and heaped manually and transported to threshing yard. . Mechanization of harvesting chickpea and wheat is desired by the farmers for saving cost and time. Some farmers tried to use the multi-crop combine harvesters that were readily available in the market and observed a seed loss. Majority of farmers in India belongs to this category of land holding. Hence mechanized harvesting of small field is the major problem. Hence, farmers are manually harvesting the crop. Manually harvesting of chickpea and wheat is very time consuming, laborious and costly.
During Shiwar feri 2016-17 at Dr PDKV Akola , the need of equipment for harvesting chickpea was discussed by the farmers in the session of “charcha satra” Hence, keeping in view the above facts, the project on modification and performance evaluation of self-propelled vertical conveyor reaper for harvesting of chickpea as well as wheat was carried with the provision of collection in box for making heap of the harvested crop.
