Embodiment 2

[0047] In Embodiment 2 of the present invention, the present invention provides a kind of small-sized automatic variable fertilizer applicator based on lidar positioning, and its implementation includes the following main steps:

[0048] Step 1: The staff injects fertilizer into the fertilizer tank 16, transmits the soil nutrient distribution map data, turns on the power switch 6 of the fertilizer spreader, waits for the self-check of the fertilizer spreader, and starts the functions of each part.

[0049] Step 2: The laser radar device 5 starts up, completes the scanning, and transmits the geographical data back to the main control device 1 and the host computer, and combines the soil nutrient distribution map to plan the traveling route and fertilization points, and calculate the amount of fertilization.

[0050] Step 3: Travel to the fertilization point, complete the fertilization, and implement the feedback of the remaining fertilizer amount in the fertilizer tank 16 to det...

Abstract

The invention discloses an automatic orchard variable rate fertilizer applicator based on a multi-line laser radar. The fertilizer applicator comprises a vehicle body, a fertilizer application device, a driving device, a laser radar device and a main control device, wherein the vehicle body comprises a carriage and a partition plate horizontally arranged in the compartment. the laser radar device is arranged at the top of the carriage and is electrically connected with the main control device; the driving device is arranged at the bottom of the carriage; the fertilizer application device is electrically connected with the main control device, is arranged on one side of the outer part of the carriage and is fixedly connected with the carriage through a fixing frame; and the main control device is arranged on the top surface of the partition plate. The automatic orchard variable rate fertilizer applicator can effectively solve the problems of uneven fertilizer application, excessive fertilizer application and low fertilizer utilization rate, and provide supplement for agricultural modernization, intelligentization and unmanned development.

Description

technical field [0001] The invention relates to the technical field of fruit tree fertilization, in particular to an automatic variable fertilization machine for orchards based on multi-line laser radar. Background technique [0002] Laser radar technology (Lidar) was first used in the field of aerial surveying and mapping in the 1970s. With the maturity of electronic devices in the 1980s, it was gradually applied to laser radar imaging and space satellite recovery and precise positioning. Now, with the continuous reduction of component costs, performance Continuously improving, it is widely used in civilian fields, intelligent robots, car assistance / automatic driving, etc. Lidar is used as an optical detection method because of its high precision, directionality, monochromaticity, coherence and many other advantages. At this stage, most of the single-line lidars used in agriculture are used for distance measurement, and the measurement accuracy becomes poor after exceeding ...
