Description

Seedbed tidal type irrigation rig is moved in the automation of a kind of greenhouse

Technical field

The present invention relates to irrigation rig, mainly is that seedbed tidal type irrigation rig is moved in a kind of greenhouse automation that is used to irrigate plant in the greenhouse.

Background technology

The development in science and technology in Development of Chinese Agriculture and greenhouse is closely bound up.The development in science and technology in greenhouse, abroad because the high and greenhouse workman of labour cost to the requirement for height of greenhouse working environment, the direction towards the automation greenhouse has had significant progress already.The automation in greenhouse has various aspects.Wherein, because the seal of growth room, greenhouse, temperature, the requirement for height of humidity causes the environment in greenhouse to be not suitable for very much the greenhouse workman and works long hours within it.And except the growth room in greenhouse provides plant grows, all there has been the workshop of supporting suitable greenhouse workman work in external greenhouse within it.And the fixedly seedbed in the greenhouse has also changed portable seedbed into.

Summary of the invention

The objective of the invention is to overcome the deficiency that prior art exists, and provide a kind of greenhouse automation that is applied on the portable seedbed to move seedbed tidal type irrigation rig.

The objective of the invention is to accomplish through following technical scheme, it comprises mobile seedbed, nutrition liquid bath, and described mobile seedbed is positioned on the rolling wheel support, moves the inner bag that the seedbed is provided with a tidal type, and plant and its growth pot are placed on the inner bag; Be connected with a feed pipe in the described nutrition liquid bath, on this feed pipe, be connected with magnetic valve, between magnetic valve and nutrition liquid bath, be connected with water pump, this water pump links to each other with feed pipe, and magnetic valve links to each other with the control computer in the external world with water pump; Described feed pipe and magnetic valve are positioned at the top of moving the seedbed stand.

As preferably, one side described inner bag be provided with an overfall and a little relief port of bore that bore is big, this overfall is height adjustable overfall, relief port is positioned at the lowest part of inner bag.

As preferably, place, the below of described overfall and relief port is provided with return duct, and this return duct is connected in the nutrition liquid bath.

Beneficial effect of the present invention is: this greenhouse automation is moved seedbed tidal type irrigation rig and can be satisfied and move the seedbed and in whole system, still can be moved; And the inner bag of the tidal type that is provided with, the overfall and the relief port that reach on the inner bag can make nutrient solution recycle, the free of contamination characteristics of the plant of have energy-saving and environmental protection, planting out.

Label in the accompanying drawing is respectively: 1, move the seedbed; 2, nutrition liquid bath; 3, inner bag; 4, feed pipe; 5, magnetic valve; 6, water pump; 7, return duct; 8, rolling wheel support; 31, overfall; 32, relief port.

Embodiment

To combine accompanying drawing that the present invention is done detailed introduction below: like accompanyingdrawing 1,2, shown in 5; The present invention includes and moveseedbed 1,nutrition liquid bath 2; Describedmobile seedbed 1 is positioned on therolling wheel support 8; Move the inner bag 3 thatseedbed 1 is provided with a tidal type, plant and its growth pot are placed on the inner bag 3; Be connected with afeed pipe 4 in the describednutrition liquid bath 2, on thisfeed pipe 4, be connected withmagnetic valve 5, be connected withwater pump 6 atmagnetic valve 5 and 2 of nutrition liquid baths, thiswater pump 6 links to each other withfeed pipe 4, andmagnetic valve 5 links to each other with the control computer in the external world withwater pump 6; Describedfeed pipe 4 is positioned at the top of movingseedbed 1 stand with magnetic valve 5.Feedpipe 4 can be moved because moveseedbed 1, so can not have rigid being connected withmobile seedbed 1.

Like accompanying drawing 3, shown in 4, one side described inner bag 3 be provided with borebig overfall 31 and thelittle relief port 32 of bore, thisoverfall 31 is height adjustable overfall,relief port 32 is positioned at the lowest part of inner bag 3.

Shown in accompanyingdrawing 1, the place, below of describedoverfall 31 andrelief port 32 is provided withreturn duct 7, and thisreturn duct 7 is connected in the nutrition liquid bath 2.No matter from the nutrient solution ofoverfall 31 outflows, or, all can flow in thereturn duct 7, flow back at last in thenutrition liquid bath 2 from the nutrient solution thatrelief port 32 flows out.The nutrition fluid power that so flow back intonutrition liquid bath 2 is recycled.

The operation principle of chamber planting plant is: except the growth room in greenhouse provides plant grows, the workshop of supporting suitable greenhouse workman work has all been arranged within it.The greenhouse workman in workshop, will move the plant treatment in seedbed intact after, the mobile seedbed of waiting for growth is moved in the growth room in greenhouse and goes growth.After the completion in vegetative period, will move the seedbed again and move the interior harvest work of handling plant between hothouse production.Deng harvest intact after, new a collection of waits growing plants is handled and is placed on the mobile seedbed that spares, repeat the process that the growth room, greenhouse is moved in mobile seedbed again.

Operation principle of the present invention is: when implementing to irrigate, computer can be opened thewater pump 6 ofnutrition liquid bath 2, so nutrient solution is sent into thefeed pipe 4 from nutrition liquid bath 2.During feed flow, nutrient solution is byfeed pipe 4 downward one side that flows into the inner bag 3 of tidal type abovemobile seedbed 1, and inner bag 3 another sides to tidal type flow then.Nutrient solution can not be sprayed onto the leaf of plant like this, takes, and only can rise (mode that flood tide) from the lower direction of plant growing basin.Computer can be controlledmagnetic valve 5 makes liquid measure to reach the liquid height that is asked in the necessarily required time.Because inner bag 3 another sides of tidal type are equipped with big overfall ofbore 31 and thelittle relief port 32 of bore, and the feed liquor amount of computer control is greater than the discharge ofrelief port 32, and liquid level can rise earlier.Overfall 31 has adjustable height.After nutrient solution rose toabove overfall 31 height, nutrient solution flowed out fromoverfall 31, made nutrient solution finally remain on the height ofoverfall 31 height.When the irrigation that is provided with to when stopping to irrigate, computer will be controlledmagnetic valve 5 and stop feed flow.Becauserelief port 32 is mounted in the minimum position of the inner bag 3 of tidal type, nutrient solution will slowly be flowed out till flowing out fully by therelief port 32 of gravitational effect from the inner bag 3 of tidal type.Like this, just satisfied the mode that tidal type is irrigated.

The present invention is not limited to above-mentioned embodiment, no matter on its shape or material formation, do any variation, every employing structural design provided by the present invention all is a kind of distortion of the present invention, all should think within protection domain of the present invention.
