Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A multi-path liquid fertilizer flow regulator is characterized in that a sealed front cover plate 12 and a sealed rear cover plate 5 are respectively arranged on the front end part and the rear end part of a cylindrical shell 1; a driving shaft 9 is rotatably arranged on the central part of the front sealing cover plate 12 through a double-row bearing group 10, a pressure liquid fertilizer inlet pipe 6 is arranged on the central part of the rear sealing cover plate 5, a front sealing plate 8 and a rear sealing plate 7 are respectively arranged on the opposite inner side wall surfaces of the front sealing cover plate 12 and the rear sealing cover plate 5, liquid outlet holes 11 are respectively coaxially arranged on the parts of the front sealing cover plate 12, the front sealing plate 8, the rear sealing cover plate 5 and the rear sealing plate 7 which are positioned on the axial lead of the driving shaft 9 and are used as the rotation center, a bracket 4 is fixedly arranged on the rear side part of the driving shaft 9 and is positioned in the cylindrical cavity of the cylindrical shell 1, sleeves 2 are uniformly arranged on the outer end part of the bracket 4 along the circumferential direction, regulating baffle discs 13 are respectively inserted into the front side part and the rear side part of the sleeves 2 in an axially movable manner, a pressure assembling spring 3 is assembled in the sleeves 2, The rear end is respectively in contact fit with the front and rear regulating and controlling baffle discs 13; the regulating and controlling baffle discs 13 on the front and rear side parts are respectively in close contact fit with the front sealing plate 8 and the rear sealing plate 7 through the extrusion of the pressure spring 3, and are in overlapped closed fit or staggered open fit with the liquid outlet holes 11 on the front sealing plate 8 and the rear sealing plate 7.
During operation, external input rotary motion passes through drive shaft 9, support 4, sleeve 3 drives regulation and control fender dish 13 at 1 internal rotations of cylinder casing, under the effect of pressure spring 3 extrusion force, regulation and control fender dish 13 of both sides closely pastes respectively and leans on preceding closing plate 8 and back closing plate 7, rotatory regulation and control fender dish 13 is in the conversion of closing and opening with a plurality of liquid holes 11 of sealed front shroud 12 and the same radius of gyration circumference position department on the sealed back shroud 7 in proper order, at this moment, the fertile liquid that gets into and is full of in the cylinder casing 1 by pressure liquid manure feed liquor pipe 6 is from a plurality of liquid holes 11 internal discontinuity outputs. The rotating speed of the driving shaft 9 is increased, so that the rotating speed of the regulating and controlling baffle disc 13 in the cylindrical shell 1 is increased, namely the liquid fertilizer output quantity of the liquid outlet hole 11 is reduced; conversely, the rotating speed of the driving shaft 9 is reduced, so that the rotating speed of the regulating baffle disc 13 in the cylinder type shell 1 is reduced, namely the liquid fertilizer output quantity of the liquid outlet hole 11 is increased. The device can realize the multi-path synchronous stepless regulation of the output quantity of the liquid fertilizer.
