Abstract

    The development of tractors with green manure seeding machines is for the seed of soybean, sun hemp and sesbania to save the labor cost and enhance the efficiency of green manure seed sowing. The device, equipped on the rear part of the tractor and the front upper part of the rotary plow, can efficiently improve sowing work. There are three transmission methods: 1. Mechanic Transmission – Use the transmission pulley at the rear wheel of the tractor to drive the main shaft of the device. The main shaft is set at different gear ratios as 15T, 18T, 21T, 24T, and 27T:16T. The seed sowing amount can be at 20-32 kg/ha by shifting the gear ratio. 2. Oil Hydraulic Transmission – Connect the flow control-valve with the external oil hydraulic of the tractor. The oil hydraulic motor is driven by the stepless speed control regulator to activate the device. The seed sowing amount can be at 20-80 kg/ha. 3. Electromechanical Transmission – The power source is the 12V 100A battery of the tractor. The DC reducing motor is driven by the stepless speed adjusting switch to activate the device. The seed sowing amount can be at 20-80 kg/ha. The operation time each hectare is at 1.5-2.5 hours, operation cost $5-6 thousand, saves the operating time of 50% more, saves the cost of operation $2.5 thousand (33%), the germination rate of these crops is higher than 86% for the integrating operation of sowing and ridging of the device, other benefits, such as inhibiting weed growth and adding organic matter in soil also prove that the machine is advantageous and multifunctional.
