Small oilseed rape seeding machine

Abstract

The invention discloses a small oilseed rape seeding machine, and belongs to the field of oilseed rape machinery. The seeding machine can complete seeding and fertilization at one time, has stable seed discharge quantity and has no seed leakage. The seeding machine is mainly composed of a rack, a seed and fertilizer box, a driving and suppressing drum and a seeder; the left lower side of the seedand fertilizer box (1) is provided with a fertilization amount adjustment knob; a driven sprocket disc (4), a seed box sprocket shaft, a fertilizer box sprocket shaft, a seed box sprocket, a fertilizer box sprocket and a seed and fertilizer driving chain (5) are arranged at the two seed and fertilizer sprockets; the bottom of the seed and fertilizer box (1) is provided with the seeder, a seeding box (6) and a seed guide tube (7); a connecting plate (9) is arranged in front of the rack (8); three furrow openers (10) in each of the front and back are arranged at the bottom of the rack; the driving and suppressing drum (11) is arranged at the lower rear part of the rack (8) and a drum shaft is arranged in the middle of the drum; bearings and bearing bases are mounted on the left side of the drum; the bearings, the bearing bases and the driving sprocket groups are mounted on the right side of the drum; a tensioning wheel assembly is fixed on the rear side of the rack (8). Seeding and fertilization of oilseed rape can be used evenly.

Description

Technical field [0001] The invention is a small rapeseed planter, belonging to the field of agricultural machinery, and specifically relates to a rapeseed sowing and fertilizing machine. Background technique [0002] At present, my country's edible oil self-sufficiency rate is less than 40%, and it is necessary to vigorously develop oil crop cultivation to solve the national oil supply security crisis. Take winter oilseed rape as an example. The Yangtze River Basin is the main production area of ​​winter oilseed rape. The annual planting area is 120 million mu. At present, nearly 80 million mu can be used for rapeseed cultivation. Traditional manual labor cannot meet the requirements of large-scale rapeseed production. The level of mechanization is quite low. To increase the total rapeseed production, we must vigorously develop the mechanization of rapeseed production. [0003] The traditional method of rapeseed planting is artificial sowing. The disadvantage is that there is no p...

AI Technical Summary

Problems solved by technology

Taking winter rapeseed as an example, the Yangtze River Basin is the main production area of ​​winter rapeseed, with an annual planting area of ​​120 million mu, and there are still nearly 80 million mu available for planting rapeseed. Traditional manual labor cannot meet the large-scale production requirements of rapeseed, and the existing planting area The level of mechanization is quite low. To increase the total output of rapeseed, we must vigorously develop the mechanization of rapeseed production

[0003] The traditional planting method of rapeseed is artificial sowing. The disadvantage is that there is no spacing between plants and rows after emergence, and the emergence rate is uneven and the density is different. In the later stage, the seedlings must be thinned and transplanted manually. , leading to heavy management work in the later period, and also affecting the yield of subsequent crops

At present, the rapeseed seeder developed and put on the market in response to the above phenomenon has solved the above problems to a certain extent, but there are also many shortcomings, such as complex structure, single function, unstable seeding volume during sowing, and missed sowing. , The situation of seeding, to a certain extent, affects the quality of sowing
