Description

Simple Seedling Raising Machine

technical field

The utility model only relates to the field of machinery, in particular to a kind of machinery for rice seedling raising.

Background technique

my country's rice planting area is nearly 500 million mu, the country with the largest rice planting area in the world, and rice production accounts for about half of my country's total grain output. With the adjustment of my country's rural industrial structure and the development of moderate-scale agricultural operations, the vast rural areas have increasingly urgent requirements for rice planting mechanization, and the area of mechanical transplanting and throwing has increased rapidly. The complete set of equipment for industrialized rice seedling raising can provide a reliable guarantee for solving the problem of rice mechanization. However, the equipment for factory seedling raising costs more than 60,000 yuan, which is unaffordable for relatively poor rural areas. Therefore, there is an urgent need for a simple seedling raising machine that does not require electricity and other equipment. The cost is low, so it is suitable for the vast rural areas.

Utility model content

The purpose of the utility model is to provide a simple rice seedling raising machine, which can complete the functions of film spreading, soil spreading, soil covering and sowing, and has low cost and is suitable for use in vast rural areas.

The technical scheme of the utility model is as follows:

The simple rice seedling raising machine includes a frame on which traveling wheels are installed, and is characterized in that the front, middle and rear sections of the frame are respectively equipped with rotating shafts for winding film, soil paving bucket grooves, and seeding bucket grooves. The bottom outlet of the soil-spreading hopper is equipped with a covering wheel, and the covering wheel includes a mandrel installed on both sides of the soil-spreading trough, and a cylindrical net cover is set on the outside of the mandrel; The bottom outlet is equipped with sowing rollers, and the surface of the sowing rollers has sockets for accommodating rice seeds.

The lower end of the covering wheel has a frame with a strip beam in the middle and is fixedly connected with the soil-laying bucket groove.

The front and rear sides of the soil covering wheel are respectively fixedly connected with a film covering board, a soil covering board and a soil laying bucket groove or a frame.

An elastic scraper is installed at the bottom of the seeding hopper groove, and the elastic scraper is attached to the seeding roller.

When the seedling raising machine is working, under the action of people pulling or power pulling, the film is first pressed under the two running wheels, and the film can rotate around the shaft. With the movement of the seedling raising machine, the film can be laid automatically. Then use the soil-covering wheel at the bottom of the soil-spreading bucket to rotate, and the soil leaks out from the cylindrical mesh cover to realize the soil covering with a thickness of about 20mm. There is a frame with a bar-shaped beam in the middle at the lower end of the soil-covering wheel, so that the film under the beam is formed when the soil is spread. There is no soil accumulation on the top, and there is a gap of 20mm in the middle. There are 4 roads in total. The total width of the soil is 1180mm, and the width of each ridge is 280mm, which is convenient for raising seedlings in the future to meet the needs of machine transplanting. After spreading the soil, cover it with a cover plate for sowing. The sowing roller rotates continuously, and the elastic scraper at the bottom of the sowing hopper groove is attached to the sowing roller to continuously scrape off the rice seeds attached to the surface of the sowing roller, leaving only the rice seeds located in the sockets on the surface of the sowing roller to achieve sowing. The height of the sowing bucket is higher, and the control of the seeding rate is controlled by the walking speed. The seedling raising machine can be drawn by manpower or by a tractor, and it can also be hung on a tractor for long-distance transportation.

The utility model can complete functions such as film spreading, soil spreading, soil covering and sowing, etc., has low cost and is suitable for use in vast rural areas.

The simple rice seedling raising machine comprises a frame 3 on which traveling wheels 5 are installed, and the front, middle and rear sections of the frame 3 are respectively equipped with a winding film 2, a soil spreading bucket groove 4, a seeding bucket groove 6, and soil spreading The bottom outlet of the bucket groove 4 is rotatably equipped with a soil-covering wheel 10. The soil-covering wheel 10 includes a mandrel installed on the two side walls of the soil-spreading bucket groove, and a cylindrical net cover is set on the outside of the mandrel; The bottom outlet of 6 is rotated and is equipped with sowing roller 7, and the surface of sowing roller 7 has the socket eye 8 of accommodating rice seed. There is a frame 12 with a strip beam in the middle of the soil covering wheel 10 lower end and is fixedly connected with the bucket groove 4 for laying soil. The front and rear sides of the soil covering wheel 10 are respectively fixedly connected with a film covering plate 11, a soil covering plate 9 and a bucket groove 4 for spreading soil or a frame 3. The bottom of the seeding hopper groove 6 is equipped with an elastic scraper, and the surface of the elastic scraper and the seeding roller 7 are bonded.

The soil in the soil paving hopper groove 4 first falls into the net cover, and of course larger soil clods cannot enter the net cover, so the effect of the net cover also plays a role of screening, filtering and crushing, and the basic thickness of the covering soil depends on the net cover. The distance from the mandrel is guaranteed (generally 20mm-25mm).

For guaranteeing that the rice seed in the sowing bucket groove 6 does not spill out, there is a dividing plate at the bottom of the sowing bucket groove 6, and there is a groove in the middle of the dividing plate, and the width of the groove is adjusted according to the diameter of the socket.
