Pneumatic precise seeder

Abstract

The invention relates to an agricultural machine, in particular to a pneumatic precise seeder. The pneumatic precise seeder is characterized in that an air bag (4) which can be filled with high-pressure air is arranged on a rack (1); an opening in one side of the air bag (4) is connected with an air ejection pipe (5); a switching valve (6) is arranged on the air ejection pipe (5); one end of the air ejection pipe (5) is opposite to a percussion port (10); the rack (1) is provided with a seed box (11) and a seed conveyor used for conveying seeds (15), and a seed conveying port (16) of the seeds (15) is opposite to the percussion port (10). The air-blasting precise seeder has the advantages that high-pressure air is adopted for percussion so that the seeds can be discharged, hole positions are precise, the single seed rate is high, furrowing is not required for soft soil, the seeds are directly hit into a plough layer, in this way, the preservation performance of soil moisture is better, and the operation cost is lowered; besides, the pneumatic precise seeder is simple in structure, stable in performance, convenient to use and capable of remarkably improving seeding quality, thereby being expected to become a new-generation seeder in place of existing products.

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.
