Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the present invention, the present invention will be further clearly and completely described below in conjunction with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, in the case of no conflict, the features in the implementation manners and examples in the present application can be combined with each other.

[0031] A kind of intelligent single-grain seeding device provided by a typical embodiment of the present invention, such as figure 1 , 2 As shown, it includes a seed box 1, an air blowing cavity assembly, a seeding tray 2 and a controller 3. The air blowing cavity assembly is arranged under the seed box 1 and communicates with the seed box 1. The outer circumference of the seeding tray 2 is evenly distributed There is a tapered hole 4 for seeding, and a seeding area 5 is provided at the bottom of the seeding tray 2 . The air blowing cavity asse...

Abstract

The invention relates to an intelligent single-grain seed metering device. The device comprises a correlation infrared sensor transmitting end and a correlation infrared sensor receiving end which arearranged at the inner side and the outer side of the circumference of each seed metering disc respectively, and a light source signal of the correlation infrared sensor transmitting end can reach thecorrelation infrared sensor receiving end through bottom holes of conical holes rotating to a vertical center line; a weighing sensor is arranged at the outer side of the bottom of each seed meteringdisc and used for weighing the weight of seeds rotating to the bottom of each seed metering disc; and the seed metering discs are connected with a main stepping motor, a seed metering area is provided with a fan-shaped protective plate capable of closing or opening a seed metering port of the seed metering area, and the fan-shaped protective plate is connected with an auxiliary stepping motor. According to the seed metering device, seeds in the conical holes of each seed metering disc are directly monitored and are regulated and controlled according to a monitoring result, so that the influence of interference factors is eliminated, the seed metering accuracy and the seed metering efficiency can be improved, and single-seed metering is realized.

Description

technical field [0001] The invention relates to a seeding device, in particular to a single-grain seeding device capable of detecting and regulating missed sowing and reseeding. Background technique [0002] The main mechanisms of the existing seed metering device are the seed box, the air-blown cavity assembly and the seed-discharging disc. There are conical holes on the peripheral surface of the seed-discharging disc. Holes, single-seed seeding requires only one seed in each cone-shaped hole. During the seeding process, there will inevitably be missed and re-seeded phenomena, which will affect the qualified rate of sowing. [0003] At present, a photoelectric sensor is usually used in the seeding pipe to monitor and alarm the phenomenon of missed broadcasting and rebroadcasting. The invention announced as 108694805A discloses a single-grain seeding detection and alarm device, which is connected to the upper and lower In the middle position of the seeding pipe of the plan...
