Abstract
The utility model discloses a fertilizer drill unit in a micro-irrigation system. The utility model is composed of a venturi pipe 1, a suction pipe 2, a regulator valve 3, and a filter 4. The venturi pipe 1 is connected with a main pipe in parallel via a water inlet pipe 5 and a water outlet pipe 6. Soluble fertilizer is sucked in via the fertilizer drill unit in a micro-irrigation system and enters the vicinity of a crop root system. The utility model has the advantages of low cost, convenient operation, high rate of automation, no additional power and no trouble. The fertilizer distribution is homogeneous, and the fertilizer is saved.
Description
The utility model is a kind of and the supporting fertilizer apparatus of irrigation system.
At present, multiple fertilizer apparatus is arranged in the irrigation system: as pump pressurization fertilizer apparatus, this device fertilising good evenness, but cost height, need additional power and frequent maintenance; Also have and adopt other fertilising filling device, but fertilising efficient is low, fertilizing amount is few, the uniformity is poor.
The purpose of this utility model is a kind of hydrodynamic force of utilizing irrigation system self of design, need not additional other power, fertilising efficient height, good evenness, irrigation system fertilizer apparatus easy to use.
The utility model is made up of Venturi tube 1, suction tube 2, control valve 3, filter 4, sees accompanying drawing.Venturi tube 1 water inlet and delivery port are the back taper bell socket, are convenient to be connected with outlet pipe 6 with water inlet pipe 5; Venturi tube 1 is made of left side pipe 11, right pipe 12, left side pipe 11 and right pipe 12 are connected by thread seal and at centre formation ring cavity 13, left side pipe 11 is provided with the suction inlet 14 that communicates with ring cavity, suction inlet 14 can be set as 1 or several, to adapt to the needs (need be set as two as suction inlet in soilless culture 14) that different soakages and multiple fertilizer apply simultaneously; Suction inlet 14 is the back taper bell socket, with the convenient suction tube 2 that connects.The Venturi tube 1 that adopts this mode to design, easily manufactured, assembling is easily; The dimensional accuracy of ring cavity guarantees easily, and the difficult obstruction of employing ring cavity, thereby makes the fertilizer soakage reliable and stable.Control valve 3 on the suction tube 2 can be regulated the fertilizer soakage, when fertilizer apparatus is not worked, closes control valve 3 and can prevent that sealing flows out from suction tube 2.Filter 4 can prevent that the impurity in the fertilizer solution from entering in the irrigation system and the obstruction that causes, filter 4 is made up of bell seat 15, piston ring 16 and filter screen 17, this simple in structure effectively and can change filter screen 17 easily, simultaneously bell seat 15 is provided with the taper bell socket and is connected with suction tube 2.Usually, Venturi tube 1 is connected in parallel with trunk line 7 by water inlet pipe 5, outlet pipe 6, elbow 8, threeway 9, suction tube 2 is placed in the uncovered fertilizer bucket 18 that fills fertilizer solution, the current that have certain pressure produce negative pressure by Venturi tube 1, suck fertilizer from suction tube 2, the fertilizer that sucks mixes with the current by Venturi tube 1, flow into trunk line 7 and further mixes enforcement irrigation in the inflow slight irrigation pipelines at different levels from trunk line 7 then with current the trunk line 7 from outlet pipe 6.This fertilizer apparatus also can with trunk line 7 use that is installed in series.
Advantage of the present utility model and good effect are: use the irrigation system pressure water be derived from the hydrodynamic force of body as the power of system's fertilizer apparatus, need not to rely on additional other power to apply fertilizer, can energy savings, reduce the fertilising cost.And this fertilizer apparatus is easy to manufacture, fertilising efficient height, fertilising good evenness, easy to install, cost is low, fault-free.
Fig. 1 is the schematic diagram of installing and using of the present utility model, and Fig. 2 is the structural representation of Venturi tube 1, and Fig. 3 is the structural representation of filter 4.
Narrate embodiment of the present utility model below with reference to the accompanying drawings.
Venturi tube 1 is connected in parallel with trunk line 7 by water inlet pipe 5, outlet pipe 6, elbow 8, threeway 9, on trunk line 7, be provided with valve 10 and be used for regulating flow by Venturi tube 1, when valve 10 is closed gradually, the flow that flows into Venturi tube 1 by water inlet pipe 5 constantly increases, when the flow that passes through Venturi tube 1 is enough big, fertilizer solution begins to suck the Venturi tube 1 interior current of also evenly sneaking into from suction tube 2, flows into trunk lines 7 by outlet pipe 6 and applies fertilizer.During valve 10 Close Alls, the soakage maximum of fertilizer solution also is the fertilizing amount maximum.Control valve 3 on the suction tube 2 also can be used to regulate the soakage of fertilizer.Fertilizer apparatus was not worked when valve 10 was all opened.In the time of need applying fertilizer, earlier fertilizer is dissolved in the uncovered fertilizer bucket 18, an end that suction tube 2 is equipped with filter 4 immerses in the interior fertilizer solution of bucket, opens control valve 3.Gradually valve-off 10, water in the trunk line 7 enters Venturi tube 1 by water inlet pipe 5, fertilizer in the fertilizer bucket 18 sucks the Venturi tubes 1 from suction tube 2 and mixes with current, enters from outlet pipe 6 that trunk line 7 and person in charge's current are further to be mixed laggard pipelines at different levels of going into irrigation system and apply fertilizer and pour water again.The big I of aperture by control and regulation valve 3 and valve 10 changes fertilising concentration and speed.Fertilising finishes, and valve 10 is all opened, and control valve 3 cuts out.This fertilizer apparatus also can be directly and trunk line 7 use that is installed in series.
Claims (2)
1, the fertilizer apparatus in a kind of irrigation system is characterized in that this device is made up of Venturi tube 1, suction tube 2, control valve 3 and filter 4, and control valve 3 and filter 4 are located on the suction tube 2; The water inlet of Venturi tube 1 and delivery port are the back taper bell socket, Venturi tube 1 is made of left side pipe 11, right pipe 12, left side pipe 11 and right pipe 12 are connected by thread seal and at centre formation ring cavity 13, left side pipe 11 is provided with the suction inlet 14 that communicates with ring cavity, suction inlet 14 can be set as 1 or several, and suction inlet 14 is the back taper bell socket; Filter 4 is made up of bell seat 15, piston ring 16 and filter screen 17, and bell seat 15 is provided with the taper bell socket and is connected with suction tube 2; Venturi tube 1 is connected in parallel with trunk line 7 by water inlet pipe 5, outlet pipe 6, elbow 8, threeway 9, and trunk line is provided with valve 10.
