New Knapsack Air Flow Rice Seedling Machine Agronomic Supporting Technology (1)
The new backpack-type air-flowing rice throwing machine is a high technology that is popularized and applied in the 21st century rice mechanization planting production. It has the advantages of saving labor, saving time, saving the province, saving labor, saving water, speeding planting, increasing production, increasing income, and saving production costs. It is of great significance to the full and reasonable utilization of agricultural resources and sustainable development, with obvious economic and social benefits. 1. Adaptability and economy (1) The new backpack-type airflow rice throwing machine is small in size, light in weight, simple in operation, convenient in use, and does not require a dedicated machine for cultivating roads. In the plains, hills, shallow mountain areas have a strong adaptability. It can also be used in one machine, which can throw parasites and spray pesticides. (2) The economic and practical investment is small. Generally, the price of a throwing machine is purchased in the range of 850 to 1100 yuan, which is suitable for purchase by family farms, villages, groups, and joint households. (3) It is usually only 12 to 15 minutes to throw one-acre fields with a new type of rice transplanter. The working efficiency is 4 to 6 times that of manual throwing and 20 times that of manual transplanting. (4) The machine has good throwing uniformity, flexible maneuverability, long throw distance, and easy adjustment. (5) About 25% of the water resources are saved, and the management of Daejeon water promotes the distribution of water by inch of water, and it is dry and wet to harvest. (6) The cost-saving effect is obvious. It can increase rice production by 10%-15% per acre, save cost, and produce high overall economic benefits. 2. New Knapsack Rice Throwing Machine The new knapsack rice throwing machine is composed of four parts: the engine, the ventilation pipe, the connection support frame, and the storage tray (with arc-shaped casting trough). The engine is powered by a two-stroke small backpack-type gasoline motorized spray duster. (1) The engine is equipped with model number and power. 1 Model: It is more suitable to use Shaanxi Weinan-fenglin brand 3MF-2, 3MF-4 and Beijing Dongfanghong brand-18AC two-stroke gasoline motorized spray duster as power machine. 2 Power: General requirements in the 1.84 ~ 2.94 kilowatts (2.5 - 4 horsepower). Speed ​​7000-7500 rpm. (2) The main technical parameters of the casting machine 1 Productivity: 4 ~ 5 acres / hour. 2 flat shooting distance: 13 to 17 meters. 3 vertical ejection: 8-10 meters. 4 into the mud depth: 5-20 mm. 5 Staffing: 3 people, including 1 operator, 2 persons for transfer. 6 The mixture ratio of gasoline and oil is 20:1.
