On the surface of canopy ceiling 200, the surface of greenhouse ceiling 200 is rinsed, the dirt on the surface of greenhouse ceiling 200 is washed away, so
Realize the cleaning to greenhouse ceiling 200.First soaked by described above, then cleaned, finally flushed cleaning flow, greenhouse
Top 200 can preferably rinsed, that is, cleaning just can once remove the dirt on the surface of greenhouse ceiling 200, without repeatedly clear
Clean, cleaning efficiency is high.
It should be noted that the first water spray portion and the second water spray portion are not limited to be opened in the hole on tube-like piece, it is arranged on
Shower nozzle on tube-like piece can also constitute the first water spray portion and the second water spray portion.Matrix can be manufactured into be possessed and greenhouse ceiling
The form of adaptable flexibility, makes it fit in greenhouse ceiling 200 naturally, so as to obtain more preferable cleaning effect.
Also, it should be noted that matrix is not limited to tube-like piece, any device for possessing cavity is used equally to as matrix.
In order that those skilled in the art are clearer to understand the present embodiment, running gear 130 is carried out specifically below
It is bright.
In the present embodiment, running gear 130 includes two frames 131, two push rods 134 and is rotated with frame 131
The travelling wheel 132 of connection, two push rods 134 are respectively fixedly disposed in two frames 131, and two frames 131 are individually positioned in
In the greenhouse gutter 210 of the both sides of greenhouse ceiling 200.Cleaning with the two ends on 120 length directions respectively with two frames 131
Connection.Staff promotes running gear 130 by push rod 134, running gear 130 by the rotation of travelling wheel 132 so as to
It is for linear motion on the length direction of greenhouse gutter 210.
In order to obtain more preferable cleaning effect, power set 140 can also be set.Power set 140 include two motors
141 and two winding guide wheels 143.Power set 140 are arranged on running gear 130, and two motors 141 are separately fixed at traveling
In two frames 131 of device 130.Two winding guide wheels 143 connect with cleaning with the two ends on 120 length directions respectively
Connect, two winding guide wheels 143 are connected with two motors 141 respectively.When motor 141 does reciprocating rotation, winding is driven to lead
Wheel 143 does reciprocating rotation, so that pull cleaning to be moved reciprocatingly on the width of greenhouse ceiling 200 with 120, to big
Canopy ceiling 200 is washed by rubbing with the hands, so as to preferably make dirt depart from from the surface of greenhouse ceiling 200.
In the present embodiment, power set 140 also include two two frames 131 for being separately positioned on running gear 130
On pressure zone guide wheel 142.Cleaning with the two ends on 120 length directions bypass respectively after two pressure zone guide wheels 142 with two
Winding guide wheel 143 is connected.Pressure zone guide wheel 142 makes cleaning band 120 keep some tension, so that cleaning band 120
Greenhouse ceiling 200 can be close to, to improve cleaning effect.
Embodiment 2
The present embodiment provides a kind of cleaning device of greenhouse ceiling 200, and compared with embodiment 1, power set 140 are or not it
Together, remainder is essentially identical.
Reference picture 3 and Fig. 4, power set 140 include 141, winding guide wheel 143 of a motor and an elastic device
144.Two ends on length direction of the cleaning with 120 are connected with elastic device 144 and winding guide wheel 143 respectively, and winding is led
Wheel 143 is connected with motor 141, and motor 141 is fixed in a frame 131 of running gear 130, and elastic device 144 is consolidated
It is scheduled in another frame 131 of running gear 130.
When winding guide wheel 143 does reciprocating rotation so as to pull cleaning band 120 to move by motor 141, elasticity dress
144 are put as cleaning is flexible with 120 motion.
When motor 141 is rotated forward, cleaning is moved with 120 to the direction away from elastic device 144, elastic device 144
It is stretched.When motor 141 is inverted, in the presence of the restoring force of elastic device 144, cleaning band 120 is near elasticity
The direction motion of device 144.The restoring force of elastic device 144 makes cleaning accelerate with 120 movement velocity such that it is able to
Bigger dynamics washes the surface of greenhouse ceiling 200 by rubbing with the hands, to reach more preferable cleaning efficiency.
Elastic device 144 can be compression spring, leaf spring, extension spring, rubber spring etc..
In the present embodiment, the two ends of elastic device 144 are respectively arranged with hook, one of to link up with and cleaning band
120 one end connection, another hook is connected with frame 131.By link up with connect, replace with it is easy to maintenance, save manpower
Financial resources.
Embodiment 3
The present embodiment provides a kind of cleaning device of greenhouse ceiling 200, and compared with embodiment 1, running gear 130 is or not it
Together, remainder is essentially identical.
Reference picture 5, running gear 130 includes two frames, 131, four travelling wheels 132 and two running motors 133. 1
Two travelling wheels 132 are respectively arranged with individual frame 131, and two running motors 133 are separately fixed in two frames 131 simultaneously
It is connected with travelling wheel 132.
Running motor 133 drives travelling wheel 132 to rotate, and running gear 130 is by the rotation of travelling wheel 132 so as in greenhouse
It is for linear motion on the length direction of gutter 210.Because greenhouse gutter 210 is typically all to be located off ground height higher
On, so as to the staff that there is correlation is difficult to touch running gear 130.Running gear 130 is by running motor
133 drive, and can effectively improve cleaning efficiency, effectively save manpower.
Section Example of the present utility model is the foregoing is only, the utility model is not limited to, for this
For art personnel, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle it
