Abstract

The utility model relates to a soil detector, in particular to a portable automatic detector for soil humidity. The portable automatic detector is structurally characterized in that operating rods are arranged at two sides of a handle box, the handle box is provided with a charging work indicator light and a power supply switch, the face of the box is provided with transparent round cover pieces with the numbers from 1 to 8, light emitting diodes are arranged below the round cover pieces, a tapered port small head at the upper end of the box is connected with an insulation thick-wall pipe with a tapered spiral soil breaking cutter at the end head, probes integrated with a humidity sensor are arranged at two sides in the insulation tick-wall pipe face at the upper end of the soil breaking cutter, and the probes on the tapered spiral soil breaking cutter are inserted into soil; when the soil is lack of water, a transistor and the diodes are not conducted, and if the soil has humidity, the water content reduces the resistance between the electrodes of the probes, and the transistor conducts the light emitting diodes under the round cover pieces with the numbers to be lightened in sequence, and the larger the humidity is, the larger the displayed number is. The portable automatic detector for soil humidity is suitable for being used in irrigation of agriculture and gardens to achieve the aims of scientifically using water and saving water resource, and is convenient to use and operate, visual and practical.

Description

Portable soil moisture automatic detector

Technical field

The utility model relates to a kind of soil detecting device.

Background technology

Many known, the agricultural of China, gardens pouring water is to comment the experience pouring mostly, thereby does not reach science week water, causes the waste of water resource.

Summary of the invention

In order to overcome above-mentioned deficiency, the utility model provides a kind of portable soil moisture automatic detector, just can reach the problem that solves above-mentioned existence.

The technical scheme in the invention for solving the technical problem is: by the tapered screw cutter that breaks ground, the portable soil moisture automatic detector that the automatic testing circuit of soil moisture is formed, shown in its circuit: by humidity sensor, detection probe, transistor VT, VD1 to VD7 diode, LED1 to LED8 light emitting diode, potentiometer, power switch, the power supply piece, the automatic testing circuit of forming, the tapered screw cutter that breaks ground, the moisture detection probe of upper end inserts in the soil because of soil when too dried, VT and VD1 to VD7 all are in cut-off state, LED1 to LED8 light emitting diode is not luminous, when soil has certain humidity, moisture in the soil makes the VT ducting capacity that diminishes of the resistance value between the moisture detection probe electrode more strong, it is more many to light the apparent numeral of looking of light emitting diode, what are lighted according to light emitting diode, the humidity size that shows soil, reach the science water according to the humidity that detects, it is characterized in that: handle box both sides are provided with control lever, handle, at its lower end is equipped with power switch, charging indicator light, relay indicating light, the box face is equipped with the transparent dome sheet that indicates 1 to 8 numeral, dome sheet lower end is equipped with LED1 to LED8 light emitting diode, the humidity measuring circuit piece is installed in left side in the box, the power supply piece of rechargeable battery and charger one is equipped with on the right side in the box, be installed in the charging socket that the lateral surface of box is connected with charger, the attachment plug that is connected with outer power plug matches, be connected with the insulation thick-walled pipe at the young head of the lower end of box tapering, the insulation thick-walled pipe link that indicates the depth dimensions mark is equipped with the tapered screw cutter that breaks ground, tapered screw breaks ground detection probe with the humidity sensor one is housed in the insulation thick-walled pipe two sides of cutter upper end, and humidity sensor is connected with the humidity measuring circuit piece by the hole in the pipe with lead.

The beneficial effects of the utility model are: portable soil moisture automatic detector, can detect the soil moisture content under the upper soll layer automatically, cheaply in agricultural, gardens pouring water, reaching the science water, save and utilize water resource, also is the instrument of the liquid water content under the investigation upper soll layer, this detecting device is simple to operation, and it is intuitively practical to detect data.
