Unique advantages of small harvester characteristics and benefits of small harvester

Small harvester has irreplaceable advantages over large harvester, so what are the characteristics and benefits of small harvester? This paper mainly introduces the characteristics, usefulness, parameters and classification of small-sized harvester, as well as the recent development and development trend of domestic small-sized harvester.

Unique advantages of small harvester

1. The harvest is clean, laid uniformly, and can be laid or stacked.

2. Adapt to plains, hills, terraces, triangles and other large and small fields and rotten mud fields.

3. It can be used to harvest wheat, rice, highland barley, hemp, beans and other crops. The harvester is equipped with responsive knives, upper and lower brackets and a safe shield. it can also harvest shrubs, forages, reeds and tea garden branches and rest the garden.

4. The small harvester has the advantages of simple operation and convenient maintenance.

5. the cost will be taken over quickly, and 30-40 yuan per mu of waterway will be harvested, and all the investment can be recovered in a few days.

The small harvester broke the homework bottleneck that the countryside could not get into the large harvester, promoted the mechanization of the harvest homework, shortened the labor cycle, and liberated people from the heavy hard labor. It is widely used to harvest wheat, rice, highland barley, hemp, beans and other crops. With responsive knives, upper and lower brackets and safe shields, you can also harvest shrubs, forages, reeds and tea garden branches and gardens. The small harvester is equipped with weak and powerful gasoline power, convenient and applicable, high efficiency, easy to carry and field work. The gasoline engine has low noise. Characteristics such as stillness and comfort. So that people everywhere will not feel exhausted in the long-term task.

The use of small harvester

Harvest rice, harvest wheat, harvest soybeans, harvest corn, and lay it up! It is used for woodland liquidation, young forest tending, secondary forest innovation and jungle tending to cut shrubs, weeds, pruning and cutting small trees. Equipped with some replaceable additional installation or equipment on the cutting and irrigation machine, it can also be used for harvesting rice and wheat and other crops, as well as pumping water, drilling holes, spraying pesticides and other lessons. The development of irrigation cutting machine is closely related to the development of small power machinery. After the second World War, chainsaw manufacturers such as the Federal Republic of Germany, the United States and Sweden used transmission shafts and cutting task parts as chainsaw accessories for mowing grass and shrubs. On this basis, Japan introduced and developed an active harvester.

Characteristics of small harvester

The small harvester has the advantages of light weight, weak power, beautiful appearance, comfortable operation, low labor intensity, clean harvesting, uniform laying, and can be laid or stacked. Adapt to plains, hills, terraces, triangles and other large and small fields and rotten mud fields. Simple operation and convenient maintenance.

Blade specifications: triple tooth blade, 40 serrated blade, 60 sawtooth blade, 80 sawtooth blade.

Three varieties of small active harvester and its development process

Small harvester can be divided into two types: side-hanging type and backpack type.

① side-mounted small harvester. It adopts hard shaft transmission, which is mainly composed of initiator, transmission system, separation aggregator, task parts, control installation and side hanging belt, etc. One end of the transmission shaft is equipped with a 0.75 ~ 2 kilowatt single-cylinder two-stroke air-cooled gasoline engine and a centrifugal friction separation aggregator, and the other end is equipped with a task component composed of a reducer and a cutting tool. There are many types of task parts, commonly used as circular saw blades, blades or nylon filaments. When doing homework, hang the hook on the aluminum alloy sleeve of the transmission shaft on the strap under the shoulder of the operator, hold the handle and swing the hard shaft laterally, you can complete the homework of cutting weeds and shrubs. The machine weighs about 6 to 12 kilograms and rotational speed is about 4500 to 5000 rpm.

② knapsack active harvester. With soft shaft transmission, the common structure is similar to the side-mounted cutting and irrigation machine, but the difference is that the starter is backed on the operator's back, the cutting parts are driven by the soft shaft, and the power of the starter is generally 0.75 to 1.2 kilowatts. The starter and the back frame are connected by two points and are equipped with special rubber parts for vibration isolation. The flexible shaft is a steel wire flexible shaft installed in the hose to transfer torque. The hose is a threaded pipe wrapped in a metal braided mesh covered with a rubber maintenance sleeve to prevent dust from invading the shaft and adhere to the smooth oil on the outside of the shaft. The cut is usually between 1.5 and 2 meters.

Hand-held small harvester

The weight of the machine tool is supported by the walking wheel, the mechanical progress is promoted by the man, and the working parts are driven by the initiator to cut and fill the work. Its structure and task are similar to portable irrigation cutters.

Hanging small harvester

Hanging behind the extension machine, the power output shaft drives the parts to twist, which is suitable for cutting and irrigation in a large area. It is mainly composed of frame, saw blade, transmission installation, hanging installation and push plate, etc. When cutting irrigation homework, the extension machine retreats, the task speed is 5 km / h, and shrubs with a diameter of 10 cm can be sawed.

Recent development and trend of small harvester in China

In recent years, the wheat combine harvester has been developed rapidly, the skill is becoming more and more mature, and the structure is becoming more and more reasonable, but the further development is facing the grand challenge of usability. Small combine harvesters have their own common usefulness, so they have their own market order.

It is a must for farmers in mountainous areas to get rich.

Yixian County, the market of Shijiazhuang in Hebei Province, is a mountainous county, growing wheat 10700 hm2 a year, mostly in the mountainous areas, with small and irregular plots. Over the years, there are only 100 combine harvesters in the county, but in 2000, small combine harvesters sold well in Jingxing Mountain area. The reason is:

The topographic features of ① mountain areas can only be used by minicomputers.

Farmers in ② mountain areas have the purchasing power due to the transfer of labor and the increase of income due to mining, ash burning, transportation and other businesses.

The price of wheat harvested by the machine is low, and the users feel that it is cost-effective, and the organic households think they can get rich, so the small-sized harvester is attractive. In 2000, when the fees for harvester homework were reduced, the average income of Taiwan could reach more than 8000 yuan.
