The invention has the beneficial effects that:
1. the invention adopts a novel rotary cutting type ploughshare mode which is developed integrally, and thoroughly changes the technical processes of design, manufacture, installation and the like of the original large plough. The front end of the plough share body and the lower end of the plough share body are opened to the working ground, and simultaneously, the plough share longitudinally drills loose, transversely cuts and twists the blades, so that soil blocks of the working ground and root stubbles of plants are minced and turned over, and the operations of turning over, raking and rotating the ground are completed at one time. The working area of the machine is 4.4 meters, the traction speed of the tractor is 5.76 km per hour, the working time is calculated every working day (18 hours), and the working time reaches 45.6 hectares, which is twice of the working area of seven furrow plough at home and abroad.
2. The invention adopts a mode of transverse in-line ploughshares and integral forward movement, and changes the inclined frame plow into a square frame plow. The resistance arm is reduced, the manufacturing process of the power arm is increased, the power consumption is thoroughly reduced, the tangible and intangible two-way loss of mechanical parts is reduced, and the aims of reducing the cost and increasing the benefit are fulfilled. The working surface of the machine is wide, the wheels on both sides of the tractor walk on the flat ground, the drawn farm machine ploughshare does not turn over large soil pieces, and the flat and straight working mode of the ploughshare overcomes the working mode of forward and oblique turning of the existing seven-furrow plough triangle ploughshare, so that the machine is labor-saving and rapid. The machine works for 45 hectares on each working day (calculated in 18 hours), the profit per hectare is calculated in 300 yuan, the gross profit per working day is 13500 yuan, the labor cost is deducted in 400 yuan, the food charge is increased by 50 yuan, the oil consumption of the oil distribution vehicle is reduced by 20 yuan, and the profit per day is 13000-14000 yuan. The land preparation in autumn every year is calculated according to 30 days, the profit is more than 39 ten thousand yuan, and the profit is 2.6 times of that of domestic seven furrow plough. This is only the benefit of a single operation, and if one to three operation fees are added, the profit can reach more than 56 ten thousand yuan.
3. The invention adopts means such as light steel production, thoroughly changes the ploughshare body and the production process of the ploughshare, and arranges the landing gear mechanism and the step blade at the upper end of the ploughshare body, so that the trafficability of the ploughshare is obviously enhanced. Meanwhile, the invention can adopt the technology that a single ploughshare mechanism is not moved, the whole ploughshare mechanism can be lifted, the rotary knife is not stopped when turning around, and the operation can be carried out after embedding, and the like. The working procedures of upturned soil sheets, soil moving blocks and the like of the existing large plow are fundamentally abandoned, time and labor are saved, and the working efficiency is greatly improved. When the machine tool works, the original working soil is only turned over in situ, and the soil blocks are crushed by cutting blades (three groups of 9 blades) and cutter bars (18 cutter bars) rotating at high speed, so that the effects of turning over, raking and rotating the soil are achieved.
4. Because of the advancement and scientificity of the novel ploughshare manufacturing technology and process, the plough only needs 50 kilowatts (87 horsepower) for working (calculated by a 210 horsepower locomotive), 80 horsepower for traction and most of mechanical power is not utilized, so that the efficiency is improved.
