Description

Greenhouse temperature controls air discharging machine

Technical field

The utility model is related to agricultural machinery, automatic field, especially a kind of greenhouse temperature controls air discharging machine.

Background technology

Day-light greenhouse is also known as brooder, is a kind of exclusive greenhouse in the northern area of China.It is it is a kind of indoors The greenhouse not heated, even if relying only on sunlight if most cold season to maintain indoor certain temperature levels, to meet The needs of vegetable crop growth.Since heating device can't be arranged in day-light greenhouse, in temperature adjusted The on off state in the multiple air ports being arranged entirely by its top realizes, large number of due to air port, such as using artificial The mode of operation drives it to be turned on and off, it is clear that can consume a large amount of manual labor, and working efficiency is also very low.Cause This, now with day-light greenhouse a kind of automation equipment that can control air port automatic opening, but this kind of dress can be set It is simple and crude to set most structure, transmission mechanism is exposed in air, often occurs stuck, movement in use and transmits unsmooth etc. ask Topic, while air port is after reaching and fully opening, it is also necessary to the motor in manual control automation equipment is stopped, that is to say, that There is still a need for artificial on duty, not smart enoughization.Therefore need one kind being capable of solution to the problems described above or device now.

Invention content

The utility model is to propose that one kind is simple in structure, design is skilful to solve the above-mentioned deficiency present in the prior art It is wonderful, it is of low cost, it is easy to make, and the greenhouse temperature control air discharging machine of air port opening and closing can be automatically controlled.

The technical solution of the utility model is：A kind of greenhouse temperature control air discharging machine, it is characterised in that：Described puts Wind turbine includes protection shell, and motor is provided in protective shell body, driving tooth is provided on the working shaft of motor, in protection shell Interior also rotational support shaft, the driving tooth are meshed with the passive tooth in shaft, and the both ends of shaft protrude from protection respectively It outside shell, and is also keyed in the end of shaft and has main shaft, silk is provided on the part that the shaft is located in protective shell body Thick stick section, is connected with stop nut in leading screw section, and the outer edge of the stop nut is connected with limit catch, limits catch End be slidably connected at be opened in protection shell on limit slideway in, it is described limit slideway both ends be also respectively provided with Limit the travel switch that catch matches, the controller controlled motor be additionally provided on protection shell, at the same with it is described Controller is also mutually furnished with temperature sensor.

The utility model compared with the existing technology, has the following advantages that：

The greenhouse temperature of this kind of structure type controls air discharging machine, and simple in sturcture, ingenious in design, rationally distributed, it is directed to The mechanism of window movement existing variety of problems in use at traditional driving greenhouse air port, it is a kind of special to design Structure, it by all critical components be all disposed within one protection shell in, prevent these driving parts or transmission parts from existing There is phenomena such as interim card, necrosis because of exposure for a long time in the course of work, while it also drives one by leading screw, nut transmission Catch movement is limited, and travel switch is configured with for this limit catch, can be realized for air switch by said mechanism It automatically controls, saves the labour of personnel.It can monitor the temperature in greenhouse at any time, and control window at air port according to temperature value Whether family is turned on and off, and realizes that the automation of greenhouse temperature is adjusted.And its manufacture craft is simple, and manufacturing cost is cheap, It can be said that it has a variety of advantages, particularly suitable for promoting and applying in the art, market prospects are very wide.

Specific implementation mode

Below in conjunction with description of the drawings specific embodiment of the present utility model.As shown in Figure 1 and Figure 2：A kind of greenhouse temperature Air discharging machine is controlled, it includes the protection shell 1 based on one, and motor 2, the work of motor 2 are provided in protection shell 1 It is provided with driving tooth 3 on axis, rotational support shaft 4, above-mentioned driving tooth 3 and the passive tooth 5 in shaft 4 are gone back in protection shell 1 It being meshed, the both ends of shaft 4 are protruded from respectively outside protection shell 1, and are also keyed in the end of shaft 4 and have main shaft 6, It is additionally provided with leading screw section on the part that shaft 4 is located in protection shell 1, stop nut 7 is then connected in leading screw section, limits spiral shell The outer edge of mother 7 is connected with limit catch 8, and the end of limit catch 8 is slidably connected at the limit being opened on protection shell 1 In slideway, it is also respectively provided with the travel switch 9 to match with limit catch 8 at the both ends of the limit slideway, in protection shell 1 On be additionally provided with the controller controlled motor 2, and be also mutually furnished with temperature sensor with this controller.

The course of work of the greenhouse temperature control air discharging machine of the utility model embodiment is as follows：It first will be at all air ports Window is connect with the main shaft 6, in this way when main shaft 6 rotates, can be driven the window actuation at air port, be realized the unlatching in air port Or close,

Motor 2 work, drive driving tooth 3 rotate, and then by 5 drive shaft 4 of passive tooth rotate, in this way with 4 key of shaft The main shaft 6 of connection can also rotate therewith, and finally drive all windows while swinging, and realize automatic opening or the pass in air port It closes；During shaft 4 rotates, since one end of limit catch 8 is plugged in limit slideway, in limit catch 8 Under effect, stop nut 7 can not follow shaft 4 to rotate together, and such stop nut 7 will rotate dynamic relative to shaft 4 Make, and since stop nut 7 is threadedly coupled with the leading screw section in shaft 4, above-mentioned action is eventually converted into stop nut 7 Along the linear reciprocating motion of shaft 4；And the limit catch 8 being fixedly connected with stop nut 7 can also slide in limit slideway, When limit catch 8 moves at some travel switch 9, travel switch 9 can send out signal to controller, and controller will control Motor 2 is stopped, and two be arranged in the present apparatus travel switch corresponds to two states in air port, i.e. fully open state respectively And closed state；

In practical work process, temperature sensor always monitors the temperature in greenhouse in real time, when temperature reaches To preset value the upper limit when, illustrate that canopy temperature is excessively high, need to open air port, temperature sensor can send out letter to controller Number, controller driving motor 2 works, and the present apparatus will be opened by main shaft with the window at air port, when limit catch 8 and first When a travel switch 9 collides, illustrate that air port has been in fully open state, the present apparatus is automatically stopped work；

When temperature reaches the lower limit of preset value, illustrate that the temperature in greenhouse is too low, needs to close air port, temperature sensor Signal, controller driving motor 2 equally are sent out to controller, the present apparatus drives the window at air port to close, works as limit by main shaft When position catch 8 and second travel switch 9 collide, illustrate that air port has been switched off, the present apparatus can also be automatically stopped work；

In addition, adjusting two travel switches 9 on protection shell 1 by way of relative position, the present apparatus can also be allowed Window unlatching is driven to be automatically stopped work afterwards to a certain degree.
