Multifunctional seed fertilizer double-sowing machine

Abstract

The invention provides a multifunctional seed fertilizer double-sowing machine comprising a rack, a seed fertilizer box, a shuttle-cutter-shaped discharging device, a walking wheel and an opening / closing operation device. The multifunctional seed fertilizer double-sowing machine is characterized in that discharging openings at the bottom of the seed fertilizer box are respectively provided with fine adjusting mechanisms; and a hoisting rack is mounted behind the rack. According to the multifunctional seed fertilizer double-sowing machine, the fine adjusting mechanisms are additionally arranged so that the sowing of crop seeds with different grain diameters and the fertilizer application of fertilizers with different grain diameters are realized; the additionally-arranged hoisting rack can adjust the height of the double-sowing machine according to different soil qualities so that the utilization efficiency and the applicable range of the double-sowing machine are improved; and furthermore, when the power of a ground range and a driving mechanism is greater, the multifunctional seed fertilizer double-sowing machine can be integrated in parallel so that the efficiency is greatly improved.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a double seeder capable of simultaneously sowing and fertilizing. Background technique [0002] I applied for a patent ZL2008200352994 earlier, which disclosed a double seeding machine for various fertilizers, which has the advantages of both sowing and fertilizing at the same time. Although this equipment can control the opening and closing of the feeding opening through the feeding control valve, the device can only control the opening and closing of the feeding port. The opening and closing of the feed opening cannot be precisely controlled for the accuracy of opening and closing, and it cannot effectively sown various crop seeds with different particle sizes such as wheat seeds, rapeseed, rice seeds, and beans, and it cannot effectively control different types of fertilizers. Deep Shi. In addition, the double seeder is installed at the rear of the drive mechanism by hard connection...

[0002] I first applied for a patent ZL2008200352994, which discloses a kind of fertilizer double sowing machine, which has the advantages of being able to sow seeds and fertilize at the same time. Although this equipment can control the opening and closing of the feeding port through the material feeding control valve, the device can only control the The opening and closing of the feed opening cannot be accurately controlled for the accuracy of opening and closing, and it cannot effectively sow seeds of various crops with different sizes such as wheat seeds, rapeseeds, rice seeds, beans, etc., nor can it effectively control the production of different types of fertilizers. Deep Shi

In addition, the double-casting machine is installed at the rear of the driving mechanism by hard connection, and its height cannot be adjusted. When the soil quality is greatly different, it will affect the use efficiency of the double-casting machine.
