A kind of greenhouse ventilation device
The present invention relates to a kind of ventilation device more particularly to a kind of greenhouse ventilation devices, belong to agricultural machinery production
Requirement of the agricultural production to automation is higher and higher, the greenhouse vegetable greenhouse of especially current north of china in winter gradually into
Enter large-scale production plantation, the ongoing operations of traditional greenhouse are relatively more, the noon on daytime in northern winter, intensity of sunshine
Bigger, temperature-rise ratio is very fast in greenhouse, at this point, needing big to greenhouse to keep the temperature in greenhouse constant
Canopy is aerated ventilation and heat dissipation, and when sun whereabouts to the west in afternoon, and the temperature in greenhouse is begun to decline, but need by
It is closed to the channel of greenhouse ventilation and heat dissipation, to guarantee that the temperature inside greenhouse is constant, current tradition temperature
Room greenhouse, this ventilating are all to reserve several openings between wall and thermal insulation plastic film at the top of greenhouse in advance, are needed
When divulging information, manually an opening will be pulled out between thermal insulation plastic film and wall, be thus aerated, when needing to close, manually
The opening between thermal insulation plastic film and wall is closed again, although carrying out heat preservation on and off by pulley blocks now with one kind
The device of ventilation opening between plastic foil and wall, but still need manually to be operated, inconvenience on and off, it is artificial to make
Industry amount is big.

Further, the motor output shaft is connect by shaft coupling with screw rod, and shaft coupling connection transmission effect is good, is improved
The rotation torsion efficiency of screw rod.
Further, the mobile bar is connect by linear bearing with sliding bar, improves cunning of the mobile bar on slide bar
Further, the ventilation of the wind direction being connected to controller vertically upward is additionally provided on the wall beside the slide bar
Fan, when the vent is open, can participate in ventilation, improve the efficiency of ventilation；The air inlet of the draft fan and go out
Air port is provided with protective net, and the article without fixed duties for preventing weight lighter is sucked into draft fan, and prevents the article fallen from pounding
Hurt the flabellum of draft fan.
The beneficial effects of the present invention are: motor operation is controlled by temperature sensor and controller, branch screw rod is driven to turn
Dynamic, it is mobile that screw rod rotation drives mobile bar to do horizontal linear, and then opens or closes the ventilation opening of greenhouse, reaches according to temperature
Temperature change inside the greenhouse of room is automatically opened or closed ventilation opening, convenient and efficient, reduces manual work, the draft fan of setting can
To help to accelerate ventilation, working efficiency is improved.

Specific introduction is done to the present invention with reference to the accompanying drawing.
Fig. 1 is overall structure of the present invention；Fig. 3 is mobile bar front view of the present invention；Fig. 4 is the mobile bar side of the present invention
As shown in Fig. 1,3,4: the present embodiment is a kind of greenhouse ventilation device, including is arranged in greenhouse ventilation opening
The temperature sensor locating the motor 3 on wall 1 and being arranged in inside greenhouse, temperature sensor pass through controller and motor 3
Connection；It is connected with screw rod 4 on 3 output shaft of motor, two are additionally provided on the wall 1 on 4 both sides of screw rod and equidistant is parallel to silk
The slide bar 6 of bar 4, two slide bars 6 and screw rod 4 are cased with a mobile bar on screw rod 4 and two slide bars 6 in same level
5, mobile bar 5 is connect by feed screw nut 13 with screw rod 4, and mobile bar 13 is slidably connected with two slide bars 6, is arranged in mobile bar 5
There is thermal insulation plastic film attachment base 12, the thermal insulation plastic film 2 at greenhouse ventilation opening is fixedly connected on the thermal insulation plastic film and connects
On joint chair 12.
In the present embodiment, screw rod bearing fixed seat 7, screw rod 4 are provided between two ends of the slide bar 6 far from wall 1
Rotation is interspersed in the screw rod bearing fixed seat 7, and screw rod 4 is avoided to shake when rotating, and ensure that the stabilization that screw rod 4 rotates
Property；And 3 output shaft of motor is connect by shaft coupling 9 with screw rod 4 in the present embodiment, the connection transmission effect of shaft coupling 9 is good, improves
The rotation torsion efficiency of screw rod 4, meanwhile, mobile bar 5 is slidably connected by linear bearing 8 with slide bar 6 in the present embodiment, is improved
Sliding stability of the mobile bar 5 on slide bar 6.
Fig. 2 is application schematic diagram of the present invention；
As shown in Figure 2: in the present embodiment, the wall 1 at greenhouse ventilation opening is arranged in motor 3 in a manner of insertion
It is interior, the space of greenhouse is made full use of, ensure that the installation of motor 3 is firm, while ensure that motor 3 will not be touched surprisingly
In order to improve the efficiency of ventilation, the present embodiment is additionally provided on the wall 1 on 6 side of slide bar to be connected with controller
The draft fan 10 of logical wind direction vertically upward can participate in ventilation when the vent is open；In the air inlet of draft fan 10
It is provided with protective net 11 with air outlet, the article without fixed duties for preventing weight lighter is sucked into draft fan 10, and prevents from falling
Article injure the flabellum of draft fan 10 by a crashing object.
The course of work is as follows:
When the temperature inside temperature sensor detects greenhouse exceeds controller setting value, transducing signal is transmitted
To controller, controller control motor 3 rotates forward within the set time drives screw rod 4 to rotate, and the drive mobile bar 5 of screw rod 4 is to remote
It is slided from 3 direction of motor, and then drives the thermal insulation plastic film 2 being connected in mobile bar 5 far from wall 1, form a ventilation opening,
Meanwhile controller control draft fan 10 rotates, the thermal current inside greenhouse is discharged, when temperature sensor detects greenhouse
When temperature inside greenhouse is lower than controller setting value, transducing signal is passed into controller, controller control motor 3 is being set
Time in reversion drive screw rod 4 rotate, screw rod 4 drive mobile bar 5 to close to 3 direction of motor slide, and then drive be connected to
Thermal insulation plastic film 2 in mobile bar 5 closes ventilation opening close to wall, meanwhile, controller control draft fan 10 stops operating,
Complete one action process.
The present invention controls motor operation by temperature sensor and controller and drives the rotation of branch screw rod, and screw rod rotation, which drives, to move
It is mobile that lever does horizontal linear, and then opens or closes the ventilation opening of greenhouse, reaches the temperature inside according to greenhouse
Variation is automatically opened or closed ventilation opening, convenient and efficient, reduces manual work, and the draft fan of setting can help to accelerate to divulge information to change
Gas improves working efficiency.
