Pneumatic Precision Seeder

Abstract

The present invention relates to an agricultural machine, that is, a pneumatic precision seeder, which is characterized in that an air bag (4) that can be filled with high-pressure gas is provided on the frame (1), and one side opening of the air bag (4) is connected out Air jet pipe (5), on the air jet pipe (5) is provided with switching valve (6), one end of air jet pipe (5) is opposite to percussion port (10), and frame (1) is provided with seed box (11) and conveying The seed injector of seed (15), the seed injection port (16) of seed (15) is opposite with percussion port (10). The beneficial effects are: high-pressure gas is used to trigger seeding, the acupuncture point is accurate, and the single seed rate is high. For relatively soft soil, the seeds can be directly injected into the plow layer without ditching. The performance of moisture conservation is better, the operation cost is reduced, and the structure is simple. It has stable performance, is easy to use, and can significantly improve the quality of sowing. It is expected to replace existing products and become a new generation of sowing models.

Description

technical field [0001] The invention relates to an agricultural machine, namely a pneumatic precision seeder. Background technique [0002] At present, the breeding level of crops such as corn is constantly improving, the cost of seeds is constantly rising, and the accuracy of the sowing rate is also getting higher and higher. The sowing point is accurate, and one seed per hole has become the goal pursued by people. And existing sowing machine not only sows acupuncture point inaccurately, and single seeding rate is also relatively low. At present, the most widely used seeders mainly include socket type, air suction type, There are several kinds of spoon type, finger clip type, etc. Among them, two seeds are often placed in the socket of the socket type, and the list rate is low. The air suction type absorbs seeds through negative pressure. From the working principle, the single seed rate should be very high, but the precision of the parts is very high, and the small defor...

Problems solved by technology

However, the existing seeder not only sows acupuncture points inaccurately, but also has a relatively low single seeding rate.

At present, the most widely used seeders mainly include socket type, air suction type, There are several kinds of spoon type, finger clip type, etc. Among them, two seeds are often placed in the socket of the socket type, and the list rate is low

The air suction type absorbs seeds through negative pressure. From the working principle, the single seed rate should be very high, but the precision of the parts is very high, and the small deformation of the parts will obviously reduce the single seed rate, and the energy consumption of the negative pressure fan is also large. , the operating cost is also high

The spoon type and the finger clip type have high requirements on the debugging ability and maintenance level of the user. The easy adjustment is lower than the air suction type seeder, and the poor adjustment is the same as the socket type, and the control is more difficult.
