The through-hole of adaptation；Upper opening 22 is equipped at the top of the screen frame 2, bottom is equipped under shed 23, and the bore of the screen frame 2 is from top to down
It is gradually reduced；The sieve 3 is made of more criss-cross filaments 31, offers multiple guide grooves on four walls of the screen frame 2
21 and the spacing of adjacent channels 21 be gradually reduced from top to down, the both ends of the filament 31 penetrate after the guide groove 21 with pitch-row tune
Regulating device 4 is connected；The pitch-row regulating device 4 is mounted on the platform 1, and it is sliding along guide groove 21 that the filament 31 is adjusted
It is dynamic.Specifically, when filament 31 is along 21 upward sliding of guide groove, the spacing of adjacent filaments 31 is gradually increased, then is indulged by more filaments 31
Square hole pitch-row made of traversed by is wrong is gradually increased；When filament 31 is along 21 slide downward of guide groove, the spacing of adjacent filaments 31 gradually contracts
It is small, then as more filaments 31 it is criss-cross made of square hole pitch-row be gradually reduced.
As further improvement of these options, the pitch-row regulating device 4 includes elevating mechanism and connecting rod 44, institute
It states elevating mechanism to be mounted on the platform 1, the connecting rod 44 is horizontally mounted on elevating mechanism, 31 both ends of filament
It is connected with connecting rod 44.The movement that 31 up and down direction of filament is realized by elevating mechanism is realized by the guide groove 21 of spacing gradual change
The movement of 31 left and right directions of filament.
As further improvement of these options, ball spout 441 and ball installation are offered in the connecting rod 44
Slot 442, the ball spout 441 are provided with 44 two sides of connecting rod, and the ball mounting groove 442 is provided with 44 two sides of connecting rod
Top is simultaneously connected to ball spout 441, and two sides open up ball spout 441 and ball mounting groove 442, and interchangeability is good；It is described thin
31 both ends of silk are connected with ball 311, and the ball 311 is mounted in ball spout 441.Specifically, in the connecting rod 44 also
It is arranged with the protective case 45 for preventing ball 311 from deviating from from ball mounting groove 442.Specifically, ball 311 can be from ball mounting groove
442 insertion ball spouts 441, and ball 311 cannot take out from the radial direction of connecting rod 44.Ball 311 can be in ball spout 441
Sliding, frictional resistance is minimum, facilitate 4 adjustment hole of pitch-row regulating device away from.

The lifting of existing filament 31.
As further improvement of these options, 21 upper end of guide groove is also provided with the guide groove for being easily installed filament 31
Hole 211, when installing filament 31, ball 311 thereon can be passed through directly from guiding groove hole 211, facilitate installation, replacement filament 31.
As further improvement of these options, on any one side wall of the screen frame 2, adjacent channels 21 are in office
Spacing is equal on what horizontal line, which ensure that through hole can make square hole pitch-row equidistantly increase or contract away from regulating device
It is small.Its principle is, referring to Fig. 8, the guide groove 21 on any side wall constitutes an isosceles trapezoid.Tri- side ac, bd, ef is taken to lead
Slot, and ae and eb is isometric, cf is isometric with fd, extends two waist of isosceles trapezoid and intersects at o point, takes up an official post in three guide grooves and take a level
Line gi, then any altitude of a triangle can reason out gh and hi etc. by the definition of similar triangles on straight line bo in Fig. 8
It is long.The ratio of the ratio of the high line of the correspondence of similar triangles, the ratio of corresponding middle line and corresponding angular bisector is equal to the likelihood ratio.Triangle
Aeo is similar to triangle gho, and the high line of triangle aeo is bo, and the high line of triangle gho is io, then the likelihood ratio is io/bo, then
The length that gh can be reasoned out is the product of io/bo and ae；Triangle ebo is similar to triangle hio, and the high line of triangle ebo is
The high line of bo, triangle hio are io, then the likelihood ratio is io/bo, then the length that can reason out hi is the product of io/bo and eb；It is comprehensive
On, it can reason out that gh and hi is isometric namely the spacing on any horizontal line of adjacent channels 21 is equal.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme should all cover within the scope of the claims and the description of the invention.
