Abstract
The utility model discloses an electric, adjustable, pneumatic and precise seeding device which consists of a sowing body, an electric suction fan, a power generator, a storage battery and an electronic commutator, wherein the electric suction fan is mounted on the sowing body and consists of a direct current brushless adjustable-speed motor and a suction fan part; the storage battery supplies power for the direct current brushless adjustable-speed motor by the electronic commutator; the power generator supplies power for the storage battery; and the motive power of the power generator takes from a diesel engine on a tractor. According to the seeding device, the power generator supplies the power for the electric suction fan by the storage battery, the negative pressure in the sowing body is stable, and the sowing rate is more than 95%; the rotating speed of the direct current brushless adjustable-speed motor can be adjusted; the negative pressure in the sowing body can be adjusted; and one seeding device can be used for sowing seeds in different shapes and different single weights.
Description
Technical field
The utility model relates to a kind of agricultural machines parts, particularly relates to a kind of electronic adjustable driven sucking precise seeder for crop seeding.
Background technology
Existing electrically driven sucking precise seeder, its structure is to be made of sowing body, electric air-suction machine and generator, generator is to be driven by the diesel engine on the tractor, when being subjected to tractor to receive oil to the edge of a field, diesel engine speed reduces, and causes the lower voltage of generator, the electric air-suction machine rotating speed that generator is directly driven reduces, and then the negative pressure that the sowing body is produced is not enough, causes planting rates low, and the highest planting rates only reaches 85%.
In addition, existing electrically driven sucking precise seeder, the electric air-suction machine of its use is the direct current carbon brush motor, this kind direct current carbon brush motor can not speed governing, the vacuum magnitude that can not regulate the sowing body according to size and the weight of seed.Be that the single motor driven sucking precise seeder can not be fit to seed-bearing sowing needs.
Summary of the invention
The utility model is the improvement to existing electrically driven sucking precise seeder.
The purpose of this utility model is for the negative pressure in the sowing body that solves existing electrically driven sucking precise seeder existence is not enough, causes the low problem of planting rates.
Another purpose of the present utility model is unadjustable for the vacuum magnitude in the sowing body that solves existing electrically driven sucking precise seeder existence, is not suitable for the problem of all planting seeds.
The technical scheme that solves first problem is:
Accumulator and electric air-suction mechatronics, generator is connected with storage battery, and accumulator is to the power supply of electric air-suction machine, and generator charges a battery.This technical scheme has solved the negative pressure not enough problem sometimes in the sowing body that generator directly causes to the power supply of electric air-suction machine.
The technical scheme that solves Second Problem is:
Make the electromotor in the electric air-suction machine into the brush DC variable-speed motor by original direct current carbon brush motor, the brush DC variable-speed motor is connected with storage battery by electronic commutator, generator is connected with storage battery, and accumulator is to the power supply of electric air-suction machine, and generator charges a battery.It is unadjustable that this technical scheme has solved sowing body that existing electrically driven sucking precise seeder the exists vacuum magnitude in producing, and is not suitable for the problem of all planting seeds.
The beneficial effects of the utility model:
1, by accumulator to electric air-suction machine power supply, solved the negative pressure not enough problem sometimes in the sowing body that generator directly causes to electric air-suction machine power supply.Planting rates of the present utility model reaches more than 95%.
2, the starting of brush DC variable-speed motor is steady, and energy loss is low, operates steadily, and reliability is high.
3, brush DC variable-speed motor good airproof performance, anti-dust, moisture resistant, larger for cultivating this dust especially, the situation that service condition is poor, the operation of electric air-suction machine is more reliable, and the life-span is longer.
4, the brush DC variable-speed motor can drive induced-draught fan and carries out speed governing, regulates the induced-draught fan suction air volume according to the big or small weight of seed, seed is inhaled pick up that more reliable accurately single seed rate is higher, has also avoided the damage of seed, and this function is very effective for special crop.
5, the rotating speed of brush DC variable-speed motor can be regulated, and namely can regulate the air quantity of the induced-draught fan of its drive, and a playscript with stage directions utility model just can be sowed the seed of difformity and different single seed weight.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model embodiment.
Embodiment
See also shown in Figure 1, present embodiment is comprised of sowing body 1, electric air-suction machine 2, generator 3, accumulator 4 and electronic commutator 5, electric air-suction machine 2 is installed on the sowing body 1, electric air-suction machine 2 is comprised of brush DC variable-speed motor and induced-draught fan, to the power supply of brush DC variable-speed motor, generator 3 is to accumulator 4 power supplies by electronic commutator 5 for accumulator 4.
Described electronic commutator is existing electronic product, can buy on market.
The power of described generator 3 is taken from the diesel engine on the tractor.
