Seed recognition device for precise crop seeding equipment

Abstract

The invention relates to a seed recognition device for precise crop sowing equipment, and discloses a seed recognition device capable of recognizing the category and size of seeds sucked into a seed discharging groove and controlling a rotating motor to drive an adjusting sliding plate to slide out of an adjusting sliding groove to adjust the size of the seed discharging groove in real time according to the category and size of the seeds. And small-particle-size seeds are prevented from being sucked into the negative-pressure cavity. The device is characterized in that the fixing assembly is composed of a fixing disc, an annular fixing barrel, a limiting disc and limiting through grooves, one end of the annular fixing barrel is connected with the fixing disc, the other end of the annular fixing barrel is connected with the limiting disc, the limiting through grooves are formed in the limiting disc at equal intervals, and a plurality of controllers are arranged in the annular fixing barrel at equal intervals in the circumferential direction; a processor is arranged in the annular fixing cylinder, the seed metering assembly is composed of a motor, a rotating shaft, a seed metering plate, a sliding groove, a seed metering disc, an adjusting sliding groove, an adjusting groove, a seed metering groove, a dustproof brush, an avoiding brush and a recognition camera, and one end of the rotating shaft is connected with the motor.

Description

technical field [0001] The invention relates to a seed identification device for precision sowing equipment for crops, which relates to a device for precision sowing equipment for crops, which can identify the type of seeds and adjust the size of a seeding trough, and belongs to the technical field of agricultural machinery. Background technique [0002] At present, the seeder has been widely used in the field of agricultural seeding. Among them, the air suction seeder is a kind of precision sowing that relies on negative pressure to absorb the seeds into the seeding holes on the seeding disc, and the seeds are sown sequentially by the rotation of the seeding disc. However, due to the different seed sizes, seeds with smaller particle sizes are easily sucked into the negative pressure chamber through the seed hole through negative pressure suction, resulting in equipment failure. The seed hole on the existing air suction seeder disc fixed size, During the sowing process, th...

[0002]At present, the seeder has been widely used in the field of agricultural seeding, among which the air suction seeder is a kind of seeding hole that absorbs the seeds to the seeding tray by negative pressure Among them, the precision seeder is a precision seeder that sows the seeds sequentially by rotating the seed disc. However, due to the different seed sizes, the seeds with smaller particle sizes are easily sucked into the negative pressure chamber through the seed hole through the negative pressure suction, resulting in equipment failure. The size of the seeding hole on the seeding disc of the existing air suction type seeder is fixed,

During the sowing process, the seeding hole cannot be adjusted in real time according to the different seed sizes, which may easily cause smaller-sized seeds to pass through the seeding hole and be sucked into the negative pressure chamber. At the same time, when sowing different types of seeds, the seeding tray needs to be Dismantling and replacing from the seeder, the steps are cumbersome, time-consuming and slow down the seeding speed

[0003] Publication No. CN210537389U discloses a sowing monitoring device, an air-suction seeder, the device includes a support, a transmitting unit and a receiving unit, and the transmitting unit and the receiving unit pass through the support Suspended above the seed tray of the air-suction planter, and the launch unit and the receiver unit are set near the exit of the seed-carrying area of ​​the air-suction planter; The hole emits light beams, and the receiving unit is used to convert the received light beams emitted by the emitting unit into signal voltages according to the situation of absorbing seeds through the suction holes at the outlet of the seed-carrying area. It is composed of a seeding disk and a seed suction hole, and several rows of seed suction holes are evenly distributed radially on the circumference of the sowing disk. The plane direction of the disc is drop-shaped, the vertical direction of the disc of the drop-shaped semi-circular hole is semi-circular, and the vertical direction of the seeding disc at the bottom of the drop-shaped semi-circular hole is provided with a vertical circular through hole, The size of the seeding tray or the seeding hole on the sowing tray of the above-mentioned device is fixed, and the seeding hole cannot be adjusted in real time according to the different seed sizes during the sowing process, and it is easy to cause smaller-sized seeds to be sucked into the seeding hole through the seeding hole. In the negative pressure chamber, at the same time, when sowing different types of seeds, it is necessary to disassemble and replace the seeding disc from the planter. The steps are cumbersome, time-consuming and slow down the sowing speed.
