Detailed Description

The technical scheme of the utility model is further explained by combining the attached drawings.

As shown in fig. 1, the intelligent precision seeder of the present embodiment mainly comprises: the device comprises a speed acquisition device, seed boxes provided with weight sensors (each seed box is provided with a weight sensor), seed box motors and a control circuit. Seed box and seed box motor set up in the seeder frame respectively one-to-one, every seed box motor is connected with the seeding shaft transmission that corresponds seed box, and speed acquisition device, weight sensor, seed box motor are connected with control circuit communication respectively. The control circuit is responsible for receiving the weight sensor signal, and is programmed in advance (the program is a routine technical means of those skilled in the art and is not part of the inventive improvement of the technical problem to be solved by the present application) and the main parameters: demand mu seeding quantity, farm implement width, seed weight, walking speed, motor speed, user set up demand mu seeding quantity, farm implement width, weighing sensor detects out seed weight to the speed of going when combining the locomotive walking calculates theoretical surplus seed weight, compares actual surplus seed weight after the regulation motor speed or fast, or slow, makes theoretical surplus seed weight and actual surplus seed weight unanimous.

The speed acquisition device of this embodiment is the navigation signal receiver that sets up in the seeder frame, and the navigation signal receiver is through receiving the speed of advancing that the satellite signal acquireed the seeder. When the navigation signal receiver works, firstly, the satellite continuously transmits signals, and the user receiver receives and processes the signals, thereby obtaining the three-dimensional position, the movement speed and the direction of the navigation signal receiver. The product of the propagation time of the coded signal from the satellite to the navigation signal receiver and the propagation speed of the radio wave is the distance between the satellite and the receiver. In order to obtain the target running speed, 4 satellites are used for transmitting coded signals and a navigation signal receiver is used for receiving the coded signals, the specific positions of the longitude, the latitude and the height of the target are determined, and finally the speed is obtained.

The speed acquisition device of this embodiment also can be replaced by photoelectric rotary encoder, and photoelectric rotary encoder installs on the land wheel of seeder. When the wheel or the land wheel rotates, the encoder generates a pulse signal, and the control circuit reads the pulse signal and converts the pulse signal into the running speed.
