Description

Seedling raising tray

Technical Field

The invention belongs to the field of plant planting equipment, and particularly relates to a seedling raising tray.

Background

The seedling raising is seedling cultivation, which means that the seedlings are cultivated in a nursery, a hotbed or a greenhouse and are ready to be transplanted into the land for planting. In a common saying, "the seedling is strong and half harvested", it can be seen that the quality of the seedling directly affects the later growth of the seedling. The seedling culture is a work with high labor intensity, time consumption and strong technical performance; different plants can adopt different seedling raising methods due to different life habits of the plants. Common seedling raising methods include a nutrition block seedling raising method, a nutrition bag seedling raising method, a floating seedling raising method and the like; the floating seedling raising method is a seedling raising method that a seedling raising tray filled with a light seedling raising matrix floats on water surface, seeds are sowed in the matrix, seedlings grow in the seedling raising matrix in a root mode, and water and nutrients can be absorbed from the matrix and a water bed.

In order to improve the germination rate of seeds and promote the growth of seedlings, a method for promoting the germination of the seeds by using magnets is provided at present, and the method is mainly realized by arranging magnets on the side wall of a seedling hole on a seedling tray; because the aperture size in the hole of growing seedlings is fixed, such device generally can only be grown seedlings to a plant, is unfavorable for the make full use of seedling tray.

Disclosure of Invention

The invention aims to provide a seedling raising tray, which solves the problem that the seedling raising tray in the prior art can only raise seedlings of plants of a single variety because the aperture of a seedling raising hole is fixed.

The seedling raising tray comprises a tray body, wherein a plurality of seedling raising holes are formed in the tray body, a plurality of magnetic metal adjusting pieces are hinged to the bottoms of the seedling raising holes, the adjusting pieces are fan-shaped, and the adjusting pieces form a circle and seal the seedling raising holes; a plurality of first electromagnets are arranged below the adjusting pieces and located in the disc body, the first electromagnets are communicated with a controller in a two-way mode through electric signals, and the controller is used for controlling the on-off of the first electromagnets and the size of electromagnetic energy.

The working principle and the beneficial effects of the scheme are as follows: the device is provided with a controller and an adjusting sheet, when a seedling raising tray is used for raising seedlings, the controller controls a first electromagnet below the adjusting sheet to be electrified, the electrified first electromagnet is provided with an adjusting sheet which magnetically attracts magnetic metal, and the adjusting sheet rotates downwards to form the minimum aperture of a seedling raising hole required for raising seedlings; in the process of adjusting the minimum aperture of the seedling growing hole, the electromagnetic energy of the first electromagnet is controlled to realize the control of the aperture of the seedling growing hole, so that the minimum diameter of the seedling growing hole can meet the aperture size of seedling growing required to be carried out, the problem of fixed aperture of the seedling growing hole in the prior art is solved, and the seedling growing of various plants is realized.

Furthermore, a plurality of second electromagnets are arranged above the adjusting sheets and connected with the controller through electric signals. When carrying out plant species and planting, can make the first electro-magnet circular telegram of adjustment sheet top through the controller to make the adjustment sheet upwards rotate, thereby make the space of below bigger, be favorable to the circulation of air, be favorable to the growth of plant.

Further, the lower terminal surface of disk body is equipped with magnet, and magnet is located the below of adjustment sheet. Through setting up magnet in the below of adjustment sheet, when moisture entered into the in-process of the hole matrix of growing seedlings, the heavy metal of aquatic can be lived in the magnet absorption, is favorable to the sprouting of seed.

Furthermore, the magnet is a third electromagnet, and the third electromagnet is communicated with the controller in a two-way mode through an electric signal. Setting the magnet as a third electromagnet, and after the third electromagnet adsorbs a certain amount of heavy metal, powering off the third electromagnet through the controller to lose magnetism; the metal adsorbed on the third electromagnet is convenient to collect.

Further, the seedling hole is a taper hole, and the adjusting piece is arranged at the smaller end of the seedling hole. The seedling culture holes are arranged to be conical holes, so that the moisture can flow downwards conveniently, and the seedling culture work can be carried out conveniently.

Further, the controller is a plc controller. The first electromagnet, the second electromagnet and the third electromagnet can be controlled simultaneously or respectively through a plc controller.

Detailed Description

The present invention will be described in further detail below by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a plc controller 1, a seedling growing hole 2, a tray body 3, a second electromagnet 4, an adjusting sheet 5, a first electromagnet 6 and a third electromagnet 7.

The embodiment is basically as shown in the attached figures 1-2: a seedling raising tray comprises a rectangular tray body 3, six conical seedling raising holes 2 are formed in the tray body 3, a plurality of magnetic metal adjusting sheets 5 are hinged to the smaller ends of the seedling raising holes 2, the adjusting sheets 5 are fan-shaped, and the adjusting sheets 5 form a circle and seal the seedling raising holes 2; the tray body 3 is also provided with a through hole which is positioned under the seedling culturing hole 2 and is communicated with the seedling culturing hole 2; one end of the through hole is provided with an annular third electromagnet 7, and the third electromagnet 7 is positioned at one end far away from the seedling hole 2; second electro-magnet 4 and first electro-magnet 6 are equipped with respectively to a plurality of regulating segments 5's upper and lower side, and first electro-magnet 6 and second electro-magnet 4 all are located disk body 3, and first electro-magnet 6, second electro-magnet 4 and third electro-magnet 7 all have plc controller 1 (like mitsubishi plcQ3.0 and above version) through the two-way UNICOM of signal of telecommunication, and the controller is used for controlling the break-make of first electro-magnet 6 and the size of electromagnetic energy.

When the seedling raising plate is used for raising seedlings of plants, such as the seedlings of cauliflower seeds; putting the substrate into the seedling growing holes 2, putting seeds into the substrate, and putting the seedling growing tray on the water surface. Before the seeds are put in, the size of the minimum diameter of the seedling hole 2 can be determined according to the size and the variety of the seeds, the first electromagnet 6 is electrified by using the plc controller 1, and the current is controlled, so that the electromagnetic energy of the first electromagnet 6 is controlled; the first electromagnet 6 attracts the adjusting sheet 5 after being electrified, and the adjusting sheet 5 rotates downwards to enable the adjusting sheet to reach the required minimum aperture of the seedling growing hole 2. When the cauliflower plants are planted or during seed seedling raising, the second electromagnet 4 can be controlled by the plc controller 1, the second electromagnet 4 attracts the adjusting sheet 5 to rotate upwards, the space below the seeds or the plants is larger, more air enters, and the seed seedling raising or the plant growth is facilitated; in the seedling or plant planting process, the third electromagnet 7 adsorbs heavy metals in the moisture, and after the third electromagnet 7 is powered off, the previously adsorbed metals can be collected. Meanwhile, the magnetic fields generated by the first electromagnet 6, the second electromagnet 4 and the third electromagnet 7 are all favorable for the germination and growth of seeds.
