Magnetic sensor based on amorphous magnetic core coil and working method thereof

The invention discloses a magnetic sensor based on an amorphous magnetic core coil and a working method thereof. The sensor consists of an amorphous magnetic core magnetic sensitive element and a working circuit, wherein the amorphous magnetic core magnetic sensitive element is a block magnetic core (1) formed by laminating a sheeting amorphous material; an induction coil (2), an insulating layer (3) and a biased coil (4) are sequentially arranged outside the block magnetic core (1); the working circuit consists of a biased circuit (5), an oscillating circuit (6) and a frequency-measuring circuit (7); and the induction coil (2) is the induction coil in the oscillating circuit (6). The working method comprises the following steps of: adjusting the working current of the biased coil to obtain the magnetic field strength H0 when the amorphous magnetic core magnetic sensitive element is under the magnetic field strength of 1 to 200e; placing the amorphous magnetic core magnetic sensitive element in a magnetic field to be measured, and measuring the resonance frequency fx output by the oscillating circuit; and obtaining the magnetic field strength Hx when the resonance frequency is fx according to the formula that fx is equal to 5.94Hx+36.51, and obtaining the strength delta Hx of the magnetic field to be measured according to the formula that delta Hx is equal to Hx-H0. The magnetic sensor and the method can be widely used for high-precision measurement on a weak magnetic field.

SEEDlING TRANSPLANTER

The present invention provides a seedling transplanter which can be used for effectively switching a preparation seedling loading part to a first state and a second state. Through swinging a transplanter body, seedling can be prevented from falling off from the preparation seedling loading part, and when the preparation seedling loading part is in the second state, the utmost upper layer and the central layer of the upper and lower directions of the preparation seedling loading part are arranged on the front side of the transplanter body, thus working efficiency can be enhanced, and a seedling box and a seedling-fetching part can be stored on preset positions. The preparation seedling loading part for loading seedlings is arranged on a supporting part (24) through a connecting rod part, and the supporting part is fixed on a driving vehicle body. Through rotatingly operating the connecting rod part, the preparation seedling loading part can be automatically switched to the first state along the front and rear direction and the second state along the upper and lower direction. A front side protruding part and a rear side protruding part are formed on the front and rear parts of the preparation seedling loading part, a front side locking part and a rear side locking part higher than the seedling loading surface of the preparation seedling loading part are formed on the front and rear side protruding parts, and a guiding surface with a low front part and a high rear part are formed on the upper surface of the front side locking part.
