Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, the utility model is described in more detail.These embodiments and accompanying drawing, only for further illustrating the utility model, do not limit the protection domain of the utility model claim.
2000 grades of adjustable nozzles 1 that the utility model center pivot sprinkling machine is evenly sprayed (are called for short shower nozzle, see Fig. 1-4) comprise shower nozzle bottom 4 and several all-purpose nozzles 2, each all-purpose nozzle 2 (or nozzle, see Fig. 2-4) two ends are equipped with screw thread, the screw thread at two ends cooperatively interacts, be interconnected by screw thread between all-purpose nozzle 2 and all-purpose nozzle 2, shower nozzle bottom 4 is threaded connection with all-purpose nozzle bottom, and all-purpose nozzle topmost 2 and truss lower end cantilever 7 are threaded connection; Spray orifice 3 is evenly distributed with in the middle part of all-purpose nozzle 2, the benchmark spray orifice radius of spray orifice 3 is 0.5mm, according to nozzle hole number difference all-purpose nozzle 2 is divided into 12 kinds of nozzle sequence numbers, namely 1. number nozzle, 2. number nozzle, 3. number nozzle, 4. number nozzle, 5. number nozzle, 6. number nozzle, 7. number nozzle, 8. number nozzle, 9. number nozzle, 10. number nozzle,
number nozzle and
number nozzle, the nozzle hole number that described 12 kinds of nozzle sequence numbers are corresponding in turn to is respectively 1,2,4,8,10,20,40,80,100,200,400 and 800.The equivalent shower nozzle of such arbitrary size can form a complete set of out with several in these 12 kinds of all-purpose nozzles, can realize 0-19.625cm
2any adjustment of the shower nozzle size of equivalence perforate sectional area, namely the equivalent opening diameter of shower nozzle is any adjustment between 0-5cm.2000 grades of adjustments continuously of shower nozzle can be realized according to 12 kinds of all-purpose nozzles, its adjustment progression can also be higher, regulate the higher required orifice number of progression more, the all-purpose nozzle shape designed owing to utilizing the utility model, the shower nozzle of the higher plate number be combined into will be longer, the lower pipe considering truss 5 distance overhead can not too near and engineering practice, and 2000 grades are enough to meet actual needs, regulate continuously so only consider 2000 grades here.Benchmark nozzle hole area in the utility model is very little, when calculating hole number less than a hole, little on the impact of total water yield.
Described in the utility model shower nozzle is further characterized in that, 1. the benchmark spray orifice radius of number nozzle, 2. number nozzle, 3. number nozzle and 4. number nozzle adopts equivalent spray orifice radius to be that 0.25mm replaces respectively, and equivalent nozzle hole number when the corresponding equivalent spray orifice radius of described 1. number nozzle, 2. number nozzle, 3. number nozzle and 4. number nozzle is 0.25mm is respectively 4,8,16 and 32.If this be due to nozzle hole number on nozzle very little, will be unfavorable for realizing even sprinkling irrigation.

Wherein A
ii-th shower nozzle equivalence perforate sectional area; R
iit is the distance of i-th shower nozzle decentre support; Δ P
ithe relative pressure being i shower nozzle is poor, and its size is relevant with all shower nozzle equivalence perforate sectional areas, is calculated by iteration of simulations;
When optimization calculates and reaches uniform irrigation, the equivalent perforate sectional area required for residue nozzle exit area place shower nozzle, determines the equivalent perforate radius of shower nozzle;
(3) equal 0.5mm for benchmark with spray orifice radius, according to the shower nozzle equivalence perforate radius of each spout obtained in step (2), calculating required spray orifice radius is the nozzle hole number of 0.5mm;
(4) select the corresponding nozzle in 12 kinds of nozzle sequence numbers, carry out Nozzle combination configuration, even if the nozzle hole number sum on all nozzles selected by each spout equals the nozzle hole number in step (3) needed for corresponding spout; Nozzle selection principle is: the nozzle number first determining maximum orifice number that required nozzle hole number can comprise, and selects the nozzle of corresponding sequence number; Next is the nozzle number of orifice number more than second, selects the nozzle of corresponding sequence number, by that analogy, until required nozzle hole number all configures; Such as: if the required nozzle hole number calculated is 1841, nozzle selection principle is: the nozzle number first determining 1841 maximum orifice number that can comprise, the nozzle of corresponding sequence number is selected; Next is the nozzle number of orifice number more than second, selects the nozzle of corresponding sequence number, by that analogy, until 1841 all configure; I.e. 1841=800 × 2+200 × 1+40 × 1+1, selects corresponding to 800 holes
number two, nozzle, one, 10. number nozzle corresponding to 200 holes, one, 7. number nozzle corresponding to 40 holes, one, 1. number nozzle corresponding to 1 hole;
(5) all nozzle arrangement combination principle selected for: when carrying out Nozzle combination configuration according to the nozzle selected in step (4), large sequence number nozzle first carries out screw thread with truss lower end cantilever 7 and is connected, and then connects from big to small successively; The nozzle of minimum nozzle sequence number is connected with shower nozzle bottom 4 by screw thread, and its bottom seals by shower nozzle bottom 4;
(6) according to above five steps, all shower nozzles are all configured complete.
The utility model is (see Fig. 5) in use, support is fixed on appropriate position, the left end of truss 5 is fixedly connected with support 6, whole truss 5 rotates centered by support 6, with one end of mounting bracket 6 for a left side, on truss 5, be equidistantly distributed with truss lower end cantilever 7 from left to right along truss 5 length direction; Truss lower end cantilever 7 is threaded with corresponding shower nozzle.
The all-purpose nozzle of 12 kinds of different sizes in the utility model, when center pivot sprinkling machine truss water inlet pressure or inflow change, when requiring certain application rate of sprinkler irrigation, on truss, each shower nozzle equivalence perforate size will change.Changing inlet pressure, reaching uniform irrigation each equivalent nozzle openings area determined by calculating, be then configured with several in the all-purpose nozzle of these 12 kinds of specifications, be combined into required shower nozzle equivalence perforate sectional area.Different shower nozzle equivalence perforate sectional area needs the nozzle of several different size to carry out assembly, and guarantee can carry out supporting installation between all-purpose nozzle, so the nozzle sets of all size is healed up, size is identical, is fixed connection between nozzle by screw thread.Spray orifice is small-sized, take nozzle diameter as 45mm, and 200, the hole being uniformly distributed 1mm radius in the middle part of nozzle is example, and nozzle length is shorter, even if during shower nozzle required for the synthesis of several nozzle sets, the total length of shower nozzle also can not be oversize, can meet use needs.To be 0 ° vertically downward, spray orifice punching 45 ° all vertically downward, direction, is more conducive to realizing downward uniform irrigation, and not to surrounding diffusion.
During center pivot sprinkling machine work, pressure and the jet size at shower nozzle water yield and shower nozzle place are all relevant.But when inlet pressure changes, in order to reach even sprinkling irrigation, the shower nozzle equivalence change of bore size does not become fixed proportion with the change of inlet pressure.When first shower nozzle equivalence bore size changes, in order to reach even sprinkling irrigation, residue shower nozzle equivalence bore size does not become fixed proportion to change yet.If the showerhead configurations method conventionally, all according to result of calculation, shower nozzle series to be redesigned at every turn, again shower nozzle is manufactured, production for irrigation sprinkler shower nozzle is brought very large trouble by this, greatly increases the manufacturing cost of shower nozzle, is not easy to produce in batches shower nozzle.
This general showerhead configurations method of the utility model design, when at ambient pressure or when requiring that the condition of different application rate of sprinkler irrigation changes, the shower nozzle equivalence perforate size required for each shower nozzle is determined through simulation calculation, that just can select in the application in these 12 kinds of all-purpose nozzles is several, is combined into the shower nozzle of equivalent perforate size required arbitrarily.So for the irrigation sprinkler of any specification, its nozzle all can be produced in batches by above-mentioned 12 kinds of specifications.
Such as, first shower nozzle equivalence perforate radius be 0.3cm, inlet pressure be 30N reach evenly sprinkling irrigation time one group of shower nozzle specification determining, but when inlet pressure changes, this group shower nozzle no longer will can realize even sprinkling irrigation, when inlet pressure gradually becomes 20N by 30N, sprinkling irrigation unevenness will reach 13%.When becoming 160mm at truss caliber from 168mm, the sprinkling irrigation unevenness of 6.99% will be caused.When current water resource anxiety, uneven sprinkling irrigation will cause very large water resource waste, crosses simultaneously and irrigates or owe to irrigate, all can affect the output of crops.Evenly just need constantly to change each jet size on truss as reached, all to go out each shower nozzle equivalence bore size by simulation calculation to produce separately more at every turn, if adopt scheme of the present utility model, only need to reconfigure nozzle, do not need again to produce shower nozzle.
Therefore the application can produce in batches according to the nozzle of the 12 kinds of specifications determined, any shower nozzle equivalence perforate size can carry out combination configuration by these several in 12 in nozzle, for producer is cost-saving, can solve by crossing a large amount of wastes of irrigating or owing to irrigate the water resource caused simultaneously, and cross the loss of irrigating and owing to irrigate the crop yield caused, realize center pivot sprinkling machine and evenly spray.
The utility model is not addressed part and is all applicable to prior art.
