Embodiment Construction

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

[0031] An intelligent single-grain seed metering 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 seed metering plate 2 and a controller 3. The air blowing cavity assembly is arranged below the seed box 1 and communicates with the seed box 1. The outer circumference of the seed metering plate 2 is evenly distributed There is a tapered hole 4 for seed metering, and a seed metering area 5 is arranged at the bottom of the seed metering plate 2 . The air blowing cavity asse...

Abstract

The invention relates to an intelligent single-grain seed metering device, which comprises an opposite-beam infrared sensor transmitting end and an opposite-beam infrared sensor receiving end respectively arranged on the inside and outside of the circumference of a seed-metering disc. The light source signal of the opposite-beam infrared sensor transmitting end can be rotated to a vertical The bottom hole of the tapered hole on the center line reaches the receiving end of the opposite-beam infrared sensor; the weighing sensor is arranged on the outside of the bottom of the seeding pan, and the weighing sensor is used to weigh the weight of the seeds that are rotated to the bottom of the seeding pan; the seeding pan and the main The stepper motor is connected, the seed metering area is provided with a fan-shaped guard plate that can close or open the seed metering port of the seed-metering area, and the fan-shaped guard plate is connected with the auxiliary stepping motor. The invention directly monitors the seed grains in the conical holes of each seed-metering plate, and regulates and controls according to the monitoring results, thereby eliminating the influence of interference factors, improving the seed-metering accuracy and seed-metering efficiency, and realizing single-grain seeding.

Description

technical field [0001] The invention relates to a seed metering device, in particular to a single-grain seed metering device with missed sowing, replay detection and regulation. Background technique [0002] The main mechanisms of the existing seed metering device are the seed box, the air blowing cavity assembly and the seed metering disc. The circumferential surface of the seed metering disc is provided with a conical hole, and the seeds are filled into the cone under the action of the air nozzle of the air blowing cavity assembly. Hole, single seeding requires only one seed in each conical hole. In the process of seeding, there will inevitably be missed sowing and rebroadcasting, which will affect the seeding qualification rate. [0003] At present, a photoelectric sensor is usually installed in the seed metering pipe to monitor and alarm the phenomenon of missed seeding and replaying. The invention announced as 108694805A discloses a single seed metering detection and a...
