Description
Technical field
The utility model relates to nursery attemperator.
Background technology
In botanical seedling culturing production process, especially in the north of cold, nursery in winter will take freeze prevention measure.Current conventional method is with the heating of burning raw coal, keeps the seedling not frost bitten in seedling rearing room; But with raw coal heating exist temperature unbalanced, need manually to attach raw coal, with serious pollution problem; And ought manually attach raw coal not in time, very easily there is freeze injury, especially at night, easily cause large stretch of nursery stock dead.
Utility model content
The purpose of this utility model has that temperature is unbalanced, easily raw freeze injury, with serious pollution problem to solve the heating of existing botanical seedling culturing burning raw coal, provides a kind of nursery root attemperator.
Nursery root attemperator, it comprises nursery casing and upper cover plate, upper cover plate is uniformly distributed penetrating hole, upper cover plate is placed in the upper surface of nursery casing, it also comprises insulating tube, temperature sensor and temperature controller, insulating tube is placed on the basal surface of seedling growing box intracoelomic cavity body, the roundabout setting of insulating tube is positioned at below the hole of upper cover plate, multiple temperature sensor is separately positioned on the diverse location of insulating tube outer surface, and the output of multiple temperature sensor is communicated with the input of the temperature sensor signal of temperature controller respectively; Insulating tube comprises electrical heating wire, inner sleeve and outer tube, electrical heating wire is spirally placed in the inner chamber body of inner sleeve, inner sleeve is placed in the inner chamber body of outer tube, the external diameter of inner sleeve and the internal diameter of outer tube leave space A, inner sleeve and outer tube are coaxially arranged, and the Current Control output of temperature controller is communicated with electrical heating wire.
The utility model keeps the temperature of suitable for plant seedling growth by the insulating tube that can generate heat being arranged on plantling root.The temperature of temperature controller to insulating tube is controlled: the temperature value detected when any one temperature sensor reach set temperature value lower in limited time, the Current Control output of temperature controller connects electrical heating wire, makes its heating work; The temperature value detected when any one temperature sensor reach set temperature value upper in limited time, the Current Control output of temperature controller disconnects the connection of electrical heating wire and power supply circuits, makes it stop heating work; Thus ensure that plantling root is in suitable temperature all the time.
It is simple that the utility model has structure, use, feature easy for installation.Using the utility model without the need to changing existing nursery casing and upper cover plate, can seedling cost be saved; Without the need to artificial monitoring, thus save labour turnover; Do not use raw coal combustion, no longer produce environmental pollution.Temperature automatically controlled, avoid the generation of unexpected freeze injury.
The utility model is simple and practical to be convenient to vast nursery enterprises and institutions and to promote the use of.
Accompanying drawing explanation
Fig. 1 is vertical view of the present utility model, and Fig. 2 is the vertical view of the upper cover plate of embodiment one, and Fig. 3 is the schematic diagram of the insulating tube duty of embodiment one, and Fig. 4 is the structural representation of the insulating tube of embodiment one.
Embodiment
Embodiment one: composition graphs 1 illustrates present embodiment, nursery root attemperator described in present embodiment, it comprises nursery casing 1 and upper cover plate 2, upper cover plate 2 is uniformly distributed penetrating hole, upper cover plate 2 is placed in the upper surface of nursery casing 1, it also comprises insulating tube 3, temperature sensor 4 and temperature controller 5, insulating tube 3 is placed on the basal surface of nursery casing 1 inner chamber body, the roundabout setting of insulating tube 3 is positioned at below the hole of upper cover plate 2, multiple temperature sensors 4 are separately positioned on the diverse location of insulating tube 3 outer surface, the output of multiple temperature sensor 4 is communicated with the input of the temperature sensor signal of temperature controller 5 respectively, insulating tube 3 comprises electrical heating wire 3-1, inner sleeve 3-2 and outer tube 3-3, electrical heating wire 3-1 is spirally placed in the inner chamber body of inner sleeve 3-2, inner sleeve 3-2 is placed in the inner chamber body of outer tube 3-3, the external diameter of inner sleeve 3-2 and the internal diameter of outer tube 3-3 leave space A, inner sleeve 3-2 and outer tube 3-3 is coaxially arranged, and the Current Control output of temperature controller 5 is communicated with electrical heating wire 3-1.
The temperature that the utility model keeps suitable for plant seedling to grow by the insulating tube 3 that can generate heat being arranged on plantling root.Insulating tube 3 is coiled pipe, below the roundabout hole being arranged on upper cover plate 2.
The temperature of temperature controller 5 pairs of insulating tubes 3 is controlled: the temperature value detected when any one temperature sensor 4 reach set temperature value lower in limited time, the Current Control output of temperature controller 5 connects electrical heating wire 3-1, makes its heating work; The temperature value detected when any one temperature sensor 4 reach set temperature value upper in limited time, the Current Control output of temperature controller 5 disconnects the connection of electrical heating wire 3-1 and power supply circuits, makes it stop heating work; Thus ensure that plantling root is in suitable temperature all the time.
The hole of upper cover plate 2 is the stretching, extension hole of plantling growth, and insulating tube 3 coordinates roundabout setting with the hole of upper cover plate 2, ensure that in plantling process of growth, plantling root is in the scope of heating of insulating tube 3 all the time.
Insulating tube 3 adopts inner sleeve 3-2 and outer tube 3-3, when in electrical heating wire 3-1 heating process, inner sleeve 3-2 is heated, the air between inner sleeve 3-2 and outer tube 3-3 is heated by the outer wall of inner sleeve 3-2, again by the outer surface of outer tube 3-3 by the heat conduction to outer tube 3-3 that add hot-air, thus to the insulation of plantling root, play the effect that plantling root is not burned.And the utility model has certain heat insulating ability, even if there is of short duration power failure or maintenance, the temperature of plantling root still can be ensured.Double-layer sleeve structure water proofing property is higher, and safety is more reliable.
Electrical heating wire 3-1 is spirally arranged has the fast advantage of firing rate, and also can ensure that heater strip 3-1 can not rupture because of stretching, has the advantage that safety is high at the position of insulating tube 3 serpentine bend.
Embodiment two: composition graphs 2 illustrates present embodiment, present embodiment is the further restriction to nursery root attemperator described in embodiment one, A >=25mm.
Space between inner sleeve 3-2 and outer tube 3-3, is used for ensuring enough air layers.
