Description

Lin-type rice seedling thrower

Lin-type rice seedling thrower is a kind of novel rice planting machine.It no longer needs manually to pull up seedlings and separate seedlings or planting; It can automatically be finished seedling sending simultaneously, separate seedlings or planting and rice transplanting; Rice shoot under throwing is embarked on journey and is stood on Tanaka equably; Line-spacing can be adjusted, and can satisfy the plantation needs of different regions.

The purpose that designs this throwing transplanting machine is: alleviate the labour intensity of agricultural production, realize the mechanization farming, voluminous grain makes agricultural foison.China is a large agricultural country, and populous, grain-production is extremely important.But agricultural machinery is also relatively backward, catch up with and surpasses developed country, will study and design the advanced person's who is fit to China's national situation agricultural machinery.

In recent years, practice is verified " rice transplanting can make increases in grain production ".But the throwing transplanting machine of rural area use at present generally also exists many shortcomings.As:

1. it is inhomogeneous to throw the rice shoot of planting: machinery also need manually be mended throwing after throwing and planting, and overstocked place manually subtracts seedling again;

2. the rice shoot lodging is more: the normal growth to rice shoot has certain influence, often needs manually to put a lodged plant upright;

3. need manually to pull up seedlings, separate seedlings or planting: machine is thrown when planting, and two people ceaselessly to add rice shoot in machine, and labour intensity is still very big;

4. because the rice shoot no regularity of dishing out, give in the future field management and the mechanized harvest of paddy rice bring difficulty.

Lin-type rice seedling thrower has overcome the deficiency of existing throwing transplanting machine.Its function mainly contains:

1. it can once be finished seedling sending simultaneously, separate seedlings or planting and three steps of rice transplanting;

2. adopt and be with native seedling sheet, saved manually operation such as pull up seedlings, separate seedlings or planting;

3. throw the rice shoot of planting regular (strain is to strain, and row is to row), and thin, close adjustable, satisfied the production demand of different regions;

4. throw the rice shoot strain strain of planting and stand on Tanaka, the phenomenon that lodges can not occur;

5. the rice shoot of throwing kind does not lack, no longer needs manually to going between Tanaka to fill the gaps with seedlings;

6. this throwing transplanting machine adaptability is strong, is not subjected to the restriction of seedling raising manners.As the land for growing field crops seedling, seedling-cultivation plate, seedling of seedling canopy and mechanization seedling all are suitable for.Especially seedling dish mechanization seedling is the most suitable.

The band soil seedling sheet specification that this machine uses is 500mm * 320mm.During machinery operation, only need a people to add on the seedling sending band unhurriedly to put the seedling sheet to get final product, not only alleviated labour intensity, the more important thing is that the rice shoot that this throwing transplanting machine is thrown kind embarks on journey, be the field management in later stage, as weed the fields, the mechanized harvest of weeding, fertilising, desinsection and paddy rice all brought convenience.Simultaneously, the neat rice shoot ventilation condition of ranks is good, and illumination is even, paddy rice is grown better and the increases in grain production good harvest.

Below in conjunction with accompanying drawing this machine is further described.
