Description

The utility model relates to devices designed for accurate and quick sampling of soil.

Known manual soil drill sampler, in which by rotating the casing, the outer part of which is made in the form of a spiral with a cutting edge, soil with an undisturbed structure is selected with a milling cutter, as a result, the undisturbed soil layer enters the sampling sleeve, and the soil destroyed by the cutting edge enters into the inter-turn space of the screw spiral and rises upwards with it, a well is formed. When a certain depth is reached, the sickle-shaped knives cut the column of the monolith, trying to meet each other, block the entrance to the sampling receptacle, and the drill is removed by the shaft end. [one].

The disadvantages of this device include the low productivity of soil sampling, the high complexity of the process.

The closest in similar features to the proposed device is a robot for sampling and analysis of soil samples, containing a drive device to ensure movement of the robot on the surface of the earth, a control unit for the drive device, a sampler for sampling soil, a laboratory for analyzing soil samples, a processor for generating analysis data soil and a transmitter for transmitting the received data to a remote center [2].

The disadvantages of the known device are:

1. bulky design, which limits the depth of sampling;

2. low accuracy of agrochemical soil analysis;

3. the use of radio frequency (cellular) equipment in various geographical areas for the transmission and sending of received data.

The objective of the utility model is to increase the efficiency and safety of the soil sampling process due to the possibility of remote control of the device in case of emergency.

The proposed device, as well as the known one, contains a self-propelled chassis with a drive device for providing movement on the surface of the earth, a control unit and a control unit, a sampler for taking soil samples, a conveyor for transporting soil samples, an on-board computer, a communication and navigation system that includes a system global positioning. Unlike the known device, the automated soil sampler contains a remote control system, including position sensors in space and obstacle sensors located around the entire perimeter of the self-propelled chassis, a video system for remote control, signaling equipment.

The proposed device allows high-quality and detailed examination to the presence and content of nutrients in the soil, which are necessary for the full development of crops.

An automated soil sampler (APP) is a self-propelled chassis 1 with a drive unit 2 and a power system - rechargeable batteries 3. A sampling mechanism is mounted on the self-propelled chassis 1, including a sampler for taking soil samples 4, a conveyor for transporting soil samples to container 5. When The automated soil sampler is equipped with an autonomous and remote control system, including: a control and monitoring unit (on-board computer) 6, space position sensors and sensors obs tacle 7 disposed around the perimeter of the motor vehicle, a video system for remote control 8, the communication and navigation system 9 10, including a system GPS / GLONASS global positioning, as well as signaling panels 11.

Before starting work, the automated soil sampler receives an individual task, formed on the basis of field mapping. To do this, each field is circled beforehand and the field circuit is stored in the on-board computer memory. After placement at the edge of the field, the APP begins to perform an individual task for sampling. Then, a grid is applied to the resulting contour, the cell of which is an elementary section of the field. At a given point in the field, an automated soil sampler, using sampler 4, takes a soil sample, and then the selected samples are loaded onto a container 5 by a conveyor for transporting soil samples. As soon as container 5 is full, the operator extracts the samples and sends them to the agrochemical laboratory for analysis. This automated soil sampler takes soil samples up to a depth of 50 cm. The APP is powered by an electric battery 3. Obstacle sensors 7 are located around the perimeter of the machine, as well as an automated soil sampler equipped with a special video monitoring system 8. When an emergency occurs, the operation of the automated soil sampler stops and the operator receives a warning signal, through the signaling equipment 11, then the operator makes a decision continuation of the work, or transfers APP on the remote control.

The automated soil sampler is controlled from a mobile or, if there is a stable connection, from a stationary control point using the navigation system 10.

This APP is characterized by versatility and sampling speed (automatically takes up to 20 soil samples), the average productivity of up to 1000 hectares per day. Automated soil sampler with remote control will significantly reduce the cost of manual labor, will make it possible to take soil samples by several robots at once, to one operator, instead of a whole team of employees. Samplers are delivered to the field by truck or trailer of a car.
