Line cooperates with pump housing closely-pitched female thread at screw thread pair, and three-level connecting rod is equipped with the piston portion with sealing function, and screw rod will pump
Internal body portion is divided into three cavitys, and the internal structure of screw pump ontology can guarantee that screw rod is screwed when screw rod rotates clockwise
Enter in the pump housing, pumping intracorporal structure makes the bodies such as the volume of level-one cavity and secondary cavity and the holding of the volume of three-level cavity in the pump housing
Product reduces, i.e., the hydraulic oil of equivalent is squeezed out secondary cavity and three-level cavity and entered in the plunger cylinder respectively to connect, make column
The plunger of plug oil cylinder is ejected, and dynamic roller is released to the direction far from fixed roll, to make fixed roll is parallel with dynamic roller gap to increase；Instead
It, when screw rod rotates counterclockwise, screw rod is back-outed to outside the pump housing, and pumping intracorporal structure makes level-one cavity and secondary cavity in the pump housing
Volume and the volume of three-level cavity keep isometric and increase, the plunger of plunger cylinder is in the gravity of dynamic roller and the bullet of pressure spring
Spring force effect is lower to be retracted, and is squeezed the hydraulic oil in plunger cylinder in the secondary cavity for returning to the pump housing and three-level cavity, move roller to
The direction of fixed roll returns, to make fixed roll is parallel with dynamic roller gap to reduce.And dynamic roller and the size for determining clearance between roll, by screw rod
Rotating cycle determines that the rotating cycle of screw rod then passes through servo motor and realizes On-line Control.Pass through the pump housing and screw-rod structure size
The reduction amount (incrementss) of setting, the reduction amount (incrementss) and three-level cavity volume of realizing I and II cavity volume is equal, protects
The oil liquid that card enters left and right plunger case is equal, and the displacement for stretching out the plunger case of two same sizes is equal, realizes fixed roll and moves
The parallel adjustment in roller gap.Since the dynamic roller of seed damage device and fixed roll are all high speed rotation parts, need to guarantee its depth of parallelism, the knot
Structure can accurately realize the parallel adjustment to roller gap.Level-one cavity and the total volume change of secondary cavity and three-level cavity body
Product variable quantity is equal, keeps the oil liquid of into and out two plunger cylinders equal, realizes the parallel adjustment to roller gap, guarantees high
The stationarity of fast rotating roller.When screw rod rotation simultaneously is compared with multi-turn number, plunger case could stretch out 1mm displacement, reduce automatic control
Difficulty, greatly improve to the parallel Adjustment precision in roller gap.
Pore 21 of the setting for connection between level-one cavity 14 and secondary cavity 15.The effect of pore is connection level-one chamber
Body and secondary cavity volume realize level-one cavity and the total variable quantity and three-level cavity volume variable quantity phase of secondary cavity volume
Deng.
The head end of the pump housing 13 is equipped with dust cover 24, and the head of the pump housing 13 is equipped with Sealing shield ring 25.Dust cover is set to the pump housing
The junction of end and screw rod seals its link position seam that may be present, prevents impurity etc. from entering；Sealing shield ring is for close
The hydraulic oil for sealing level-one inside cavity, prevents its spilling.
The bottom end setting connecting rod 26 of swing arm 3 is connect with pressure spring 27.
The outer diameter of primary connecting rod 18 is equal with the internal diameter of level-one cavity 14；The outer diameter of second level screw rod 19 is less than primary connecting rod
18；The outer diameter of three-level connecting rod 20 is less than second level screw rod 19, and the outer diameter of piston 31 is equal with the internal diameter of three-level cavity 16；Secondary cavity
15 internal diameter is greater than the internal diameter of level-one cavity 14 and three-level cavity 16, and the internal diameter of three-level cavity 16 is less than the interior of level-one cavity 14
Diameter.
The plunger of plunger cylinder 7 and the side wall vertical connection of swing arm 3, the plunger of plunger cylinder 7, which is equipped with, adjusts 28 He of bolt
Fastening nut 29.Since plunger cylinder uses same size, when the hydraulic oil volume of into and out plunger cylinder is identical, column
The stroke that plug is stretched out or retracted is equal and synchronous, and it is initial between plunger and dynamic roller for adjusting to adjust bolt and fastening nut
Gap, and the bolt that adjusts by adjusting two plungers guarantees to move the initial parallel degree between roller and fixed roll.
When operation, opening servo motor 11 makes it that screw rod 12 be driven to rotate, when needing to tune up the roller gap of destroyer, according to
Gap width actually required determines that the circle number that screw rod 12 rotates, driving screw rod 12 rotate clockwise, and screw rod 12 is screwed into the pump housing
In 13, piston 31 is squeezed into three-level cavity 16, and the hydraulic oil in level-one cavity 14 is passed through pore 21 to two by primary connecting rod 18
It is squeezed in grade cavity 15, the bodies such as the volume of level-one cavity 14 and secondary cavity 15 and the holding of the volume of three-level cavity 16 in the pump housing 13
Product reduces, i.e., the hydraulic oil of equivalent is squeezed out secondary cavity 15 and three-level cavity 16 and entered in the plunger cylinder 7 respectively to connect,
It is ejected the plunger of plunger cylinder 7, dynamic roller 1 is released to the direction far from fixed roll 5, the gap between fixed roll 5 and dynamic roller 1
When increasing to the width of needs in parallel, seed damage operation can be started by closing servo motor 11 and being started roller 1 and rotate；It needs to adjust
When the roller gap of small destroyer, gap width according to actual needs determines the circle number that screw rod 12 rotates, and drives 12 inverse time of screw rod
Needle rotation, screw rod 12 back-outs to outside the pump housing 13, and the structure in the pump housing 13 makes level-one cavity 14 and secondary cavity 15 in the pump housing 13
Volume and the volume of three-level cavity 15 keep isometric and increase, and plunger cylinder 7 is in the gravity of dynamic roller 1 and the spring of pressure spring 27
The lower retraction of power effect, is squeezed the hydraulic oil in plunger cylinder 7 in the secondary cavity 15 and three-level cavity 16 for returning to the pump housing 13, moves
Roller 1 is returned to the direction of fixed roll 5, when fixed roll 5 is parallel with dynamic 1 gap of roller is decreased to the width needed, closes servo motor 11
Seed damage operation can be started by being started the rotation of roller 1.
