Description

Agricultural unmanned rice seeder

Technical Field

The utility model relates to an unmanned air vehicle technique field, in particular to agricultural unmanned aerial vehicle's disseminator.

Background

Agricultural unmanned aerial vehicle flies the accuse through ground remote control or navigation, realizes spraying the operation, can spray medicament, seed, powder etc..

But plant protection unmanned aerial vehicle among the prior art, its seeding case has the technical problem that the seeding homogeneity is poor when seeding crops such as rice.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing an agricultural unmanned aerial vehicle rice disseminator to solve the current poor technical problem of agricultural unmanned aerial vehicle seeding case seeding rice homogeneity.

The utility model discloses an agricultural unmanned aerial vehicle rice seeder, including seed case, seed case is formed by upper housing and lower housing through bolted connection, be provided with the charge door on the upper housing, the lower housing includes the section of gathering materials that the cross section is the shape of falling the eight and connects in the U-shaped groove section of gathering materials the section lower extreme;

two parallel discharge rollers are arranged in the U-shaped groove section, each discharge roller comprises a roller shaft with two ends arranged on the side wall of the seed box and a sponge roller arranged on the roller shaft, a motor for driving the roller shafts to rotate is arranged on the side wall of the seed box, and each roller shaft is correspondingly provided with one motor; tooth grooves for containing seeds are uniformly formed in the circumferential surface of the sponge roller, and the length direction of each tooth groove is parallel to the roller shaft;

the inner arms at two sides of the U-shaped groove section are respectively provided with seed baffle plates with the cross sections in the shape of a Chinese character 'jin', the upper side surfaces of the two seed baffle plates are arranged in a V shape, a seed discharging notch is formed between the two seed baffle plates, the lower side surfaces of the two seed baffle plates are arc surfaces matched with the discharging roller, and the distance between the arc surfaces and the outer circular surface of the discharging roller is less than or equal to 1 mm;

the bottom of the U-shaped groove section is provided with a rectangular seed sowing port.

Further, the distance between the arc surface and the outer circular surface of the discharge roller is 0.5 mm.

The utility model has the advantages that:

1. the utility model discloses agricultural unmanned aerial vehicle rice disseminator, its sponge running roller that utilizes motor drive to be provided with the tooth's socket that holds the seed discharges the seed of incasement, and is controllable and stable high through motor speed for this disseminator can be continuous, even discharge the seed, can solve the poor technical problem of current agricultural unmanned aerial vehicle seeding case seeding rice homogeneity.

2. The utility model discloses agricultural unmanned aerial vehicle rice disseminator, its sponge running roller have better pliability, arrange the material in-process, when the seed card is between two sponge running rollers, the sponge running roller can not press from both sides the seed bad, has consequently avoided the problem at seed metering in-process damage seed.

3. The utility model discloses agricultural unmanned aerial vehicle rice disseminator, its two seed baffles that set up only let appropriate amount of seed fall from the seed metering notch between the two, avoided the seed and sponge running roller large tracts of land contact and caused jamming, jam problem; and the distance clearance between the circular arc surface of the seed baffle plate and the outer circular surface of the discharge roller is smaller, so that the problem of clamping stagnation caused by the fact that seeds enter between the seed baffle plate and the discharge roller is avoided.

Detailed Description

The invention is further described with reference to the following figures and examples.

This embodiment agricultural unmanned aerial vehicle rice disseminator, including seed case 1, seed case 1 comprises last casing 101 and lower casing 102 through bolted connection, upward be provided with charge door 2 on the casing, casing 102 includes that the cross section is for the section 1021 of gathering materials of the splayed and the U-shaped groove section 1022 of connecting at the section lower extreme that gathers materials down.

Two parallel discharge rollers 3 are arranged in the U-shaped groove section, each discharge roller comprises a roller shaft 301 with two ends arranged on the side wall of the seed box and a sponge roller 302 arranged on the roller shaft, a motor 4 for driving the roller shafts to rotate is arranged on the side wall of the seed box, and each roller shaft is correspondingly provided with one motor; tooth grooves 303 for containing seeds are uniformly formed in the circumferential surface of the sponge roller, and the length direction of the tooth grooves is parallel to the roller shaft.

The inner arms at two sides of the U-shaped groove section are respectively provided with a baffle plate 5 with a cross section shaped like a Chinese character 'yi', and the baffle plates 5 can be integrally formed with the lower shell in specific implementation and can also be fixed on the lower shell in a bolt or welding mode and the like. The upper side surfaces of the two seed baffle plates are arranged in a V shape, a seed discharging notch 6 is formed between the two seed baffle plates, the lower side surfaces of the two seed baffle plates are arc surfaces matched with the discharging roller, the distance between each arc surface and the outer circular surface of the discharging roller is preferably less than or equal to 1mm, and the distance between each arc surface and the outer circular surface of the discharging roller is specifically designed to be 0.5mm in the embodiment.

The bottom of the U-shaped groove section is provided with a rectangular seed discharging port 7.

This embodiment agricultural unmanned aerial vehicle rice disseminator, its sponge running roller that utilizes motor drive to be provided with the tooth's socket that holds the seed is discharged the seed in the seed case, and is controllable and stable high through motor speed for this disseminator can be continuous, even discharge the seed, can solve the poor technical problem of current agricultural unmanned aerial vehicle seeding case seeding rice homogeneity.

And agricultural unmanned aerial vehicle rice disseminator in this embodiment, its sponge running roller has better pliability, arranges the material in-process, when the seed card was between two sponge running rollers, the sponge running roller can not press from both sides the seed bad, has consequently avoided damaging the problem of seed at the seed metering in-process.

In the unmanned rice planter for agricultural use in the embodiment, the two seed baffles only allow a proper amount of seeds to fall from the seeding notch between the two seed baffles, so that the problems of clamping stagnation and blockage caused by large-area contact of the seeds and the sponge roller are avoided; and the distance clearance between the circular arc surface of the seed baffle plate and the outer circular surface of the discharge roller is smaller, so that the problem of clamping stagnation caused by the fact that seeds enter between the seed baffle plate and the discharge roller is avoided.
