摘要：
The invention described in this application relates to the development of a machine for addressing the nursery requirement of horticulture sector. It has been developed at Industrial Extension Project, Coimbatore under Central Institute of Agricultural Engineering (Bhopal) in collaboration with Indian Institute of Spices Research, Calicut. The machine is named as "POWER OPERATED POTTING MACHINE FOR HORTICULTURAL NURSERY. This continuous type machine is capable of mixing, pulverizing, sieving and filling potting mixture (soil: granite powder: compost at 2:1:1 ratio v/v) in poly-bags at the desired quantity (250, 500,1,000g, etc.). The machine consists of 3-hp motor (3- phase), paddles for mixing and pulverizing, sieve attached in slider-crank mechanism for sieving, and electronic instrumentation including load cell for dispensing potting mixture at a set quantity and timing. In addition to the electronic dispensing unit, a pedal has also been provided for operator to manually control quantity of potting mixture. Germination studies conducted in the mist chamber using machine-made potting mixture and the quality of the potting mixture based on the textural analysis were found encouraging. The root developments with the machine made potting mixture are very good as observed in the germination study. The electronic vending unit fills desired quantity with 90% accuracy, and this is acceptable in nursery practices. The cost of the unit is approximately Rs. 1.00 lakh, and its capacity is 100 kg/hour. About 1,600 bags of 500-g capacity can be filled in 8 hours by engaging two labourers, while only 300-350 bags were filled in the conventional method. Cost of bagging by machine is Rs. 320 per 1,000 bags, and it is Rs. 1,140 in the manual method. There is about 70 % cost saving and 80% time-saving through machine-filling. The device is shown in the Figures 1, & 2 and Plates 1 & 2 as enclosed.
