[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-7 As shown, a shear emulsification mechanism for the production of pesticide emulsifiable concentrates comprises a housing 1 and a discharge port 2, including:

[0031] A filter plate 4 for filtering impurities, which is fixedly arranged on the inner wall of the housing 1;

[0032] The shear blade 3 driven by the driving motor comprises a bottom blade 31 arranged on the output shaft of the driving motor, and a rectangular opening is opened in the bottom blade 31;

[0033] The deflection leaf 32 is rotatably arranged in the rectangular opening, and the rotation stroke thereof includes:

[0034] In the initial position, the deflection leaf 32 overlaps the rectangular opening;

[0035] At the end position, the deflection leaf 32 is staggered from the bottom leaf 31, and the rectangular opening is opened;

[0036] The deflection leaf 32 is pressed to switch from the initial position to the final position, and the output torque direction of the driving motor is always positive.

[0037] Specifically, the discharge port 2 is equipped with a cover plate for inspecting the inside of the device, and the output torque direction of the driving motor is always positive, that is, clockwise.

[0038] Furthermore, the emulsion is poured into the casing 1, and the emulsion is sheared by the shearing blade 3. At this time, the deflection blade 32 is in the initial position, and the deflection blade 32 overlaps with the rectangular opening on the bottom blade 31, so that the deflection blade 32 and the bottom blade 31 form a complete blade surface, and the emulsion is stirred together, so that the emulsion becomes finer after passing through the filter plate 4. When there are agglomerated impurities that are not completely emulsified in the emulsion, the pressure of the local emulsion on the shearing blade 3 becomes greater, so that the deflection blade 32 rotates from the initial position. At the termination station, the deflection leaf 32 under the station is staggered with the bottom leaf 31. Since the limiting groove 35 is provided on the bottom leaf 31, the deflection leaf 32 stops after rotating to a predetermined angle relative to the bottom leaf 31. The contact surface between the deflection leaf 32 and the impurity is inclined, so that the contact area is reduced. At this time, the rectangular opening is open, and the deflection leaf 32 under the termination station divides the agglomerated impurities, so that the divided impurities enter the rectangular opening through the upper and lower sides of the deflection leaf 32 respectively, so as to avoid excessive pressure of the agglomerated impurities on the shear blade 3 as a whole.

[0039] In the above technology, through the design of the deflection leaf 32, when the pressure of the local emulsion on the shearing blade 3 increases, the deflection leaf 32 is staggered with the bottom leaf 31 and rotates to a predetermined angle relative to the bottom leaf 31 and then stops, thereby dividing the agglomerated impurities, so that the divided impurities enter the rectangular opening through the upper and lower sides of the deflection leaf 32 respectively, making the impurities more delicate and reducing agglomeration, and also preventing the agglomerated impurities from causing excessive pressure on the shearing blade 3.

[0040] As an embodiment further provided by the present invention, a slot 321 is provided on the deflection leaf 32, and the shearing blade 3 further includes a protrusion 341. When the deflection leaf 32 is in the initial position, the slot 321 and the protrusion 341 are engaged with each other.

[0041] Specifically, a torsion spring is provided on the deflection leaf 32, so that the deflection leaf 32 always has a tendency to rotate toward the termination position. During normal use, the deflection leaf 32 is located at the initial position. At this time, the slot 321 and the protrusion 341 are engaged with each other, so that the deflection leaf 32 remains overlapped with the rectangular opening, and the torsion spring stores elastic energy at this time; when the deflection leaf 32 encounters agglomerated impurities, it is subjected to greater pressure, causing the deflection leaf 32 to be deflected under pressure and drive the slot 321 to disengage from the protrusion 341, and the elastic potential energy of the torsion spring is released, driving the deflection leaf 32 to rotate toward the termination position.

[0042] As another embodiment further provided by the present invention, a movable leaf 33 is slidably provided on the bottom leaf 31 , and the protrusion 341 is squeezed out of the slot 321 as the movable leaf 33 approaches the bottom leaf 31 .

[0043] Specifically, the movable leaf 33 is arranged on the side of the bottom leaf 31 shearing the emulsion. When the emulsion has a large resistance to the shearing leaf 3, the movable leaf 33 will be pushed toward the bottom leaf 31 first. At this time, the protrusion 341 is squeezed out of the groove 321 as the movable leaf 33 approaches the bottom leaf 31, so that the deflection leaf 32 loses the restriction of the protrusion 341 and deflects to the end position under the action of the torsion spring.

[0044] An inclined surface can be provided on the adjacent surfaces of the movable leaf 33 and the bottom leaf 31, and the inclined surface can guide the protrusion 341 to slide away from the slot 321 when the movable leaf 33 and the bottom leaf 31 approach each other; or a wedge block can be provided on the protrusion 341, and the wedge block can be squeezed out as the movable leaf 33 and the bottom leaf 31 approach each other, thereby driving the protrusion 341 to disengage from the slot 321; or other transmission methods known to those skilled in the art can be used.

[0045] As another embodiment further provided by the present invention, an elastic member 34 is disposed on the movable leaf 33 , and the protrusion 341 is disposed on the elastic member 34 .

[0046] Specifically, the elastic member 34 is located between the movable leaf 33 and the bottom leaf 31, and the protrusion 341 is located in the middle of the elastic member 34. When the movable leaf 33 and the bottom leaf 31 are pressed by the emulsion and approach each other, the elastic member 34 is bent. At this time, the elastic member 34 supports the movable leaf 33 by its own elastic force. When the pressure is small, the protrusion 341 extends out of the inside of the elastic member 34. Figure 6 In the state shown, the protrusion 341 and the slot 321 are engaged with each other, limiting the deflection leaf 32 to the initial position; when the pressure of the emulsion is greater than the elastic force of the elastic member 34, the elastic member 34 bends and drives the protrusion 341 to retract into the elastic member 34. Figure 5 In the state shown, the protrusion 341 is disengaged from the locking groove 321, and the deflection leaf 32 is not restricted and rotates under the action of the torsion spring.

[0047] As another embodiment further provided by the present invention, a sleeve 5 is provided on the output shaft of the driving motor, and a movable plate 41 is slidably provided on the sleeve 5 through a keyway, and the movable plate 41 is slidably provided on the filter plate 4.

[0048] Specifically, a wavy guide groove 52 is provided on the sleeve 5. The sleeve 5 can be driven by a driving motor. When the sleeve 5 rotates, the movable plate 41 is driven to move along the guide groove 52 through the key groove. Since the movable plate 41 is slidably arranged on the filter plate 4, and the filter plate 4 is fixedly arranged on the inner wall of the casing 1, the movable plate 41 is guided by the guide groove 52 to move back and forth in the vertical direction, and the emulsion on the movable plate 41 and the filter plate 4 is stretched or squeezed, so that the emulsion is more delicate and impurities are reduced.

[0049] As another embodiment further provided by the present invention, a tooth particle 51 is disposed on the upper end surface of the sleeve 5 , and a clamping block 36 that can be engaged with the tooth particle 51 is disposed on the rotating shaft of the deflection leaf 32 .

[0050] Specifically, when the deflection leaf 32 rotates to the end position, the position of the block 36 is fixed due to the restriction of the limiting groove 35. At this time, the block 36 on the rotating shaft is tangent to the tooth particle 51. At this time, the deflection leaf 32 is driven by the output shaft of the driving motor. Since the output torque direction of the driving motor is always positive, that is, clockwise, the block 36 is driven to rotate in the positive direction with the output shaft, thereby driving the sleeve 5 to rotate in the positive direction through the tooth particle 51, thereby driving the movable plate 41 to reciprocate up and down in the vertical direction; after the emulsion is discharged, when the deflection leaf 32 needs to be reset, the cover plate can be removed, and then The sleeve 5 can be rotated in the opposite direction by hand, and the block 36 can be driven to rotate in the opposite direction by the sleeve 5, so that the deflection leaf 32 returns to the initial position. At this time, since the emulsion is completely emptied, the movable leaf 33 is not affected by the pressure, and maintains a certain distance with the bottom leaf 31 under the elastic support of the elastic member 34, and the elastic member 34 is not bent by force, so that the protrusion 341 extends out of the elastic member 34 in the direction of the deflection leaf 32. When the deflection leaf 32 returns to the initial position, the slot 321 and the protrusion 341 are driven to engage with each other, so that the deflection leaf 32 overlaps the rectangular opening.

[0051] Working principle: the emulsion is poured into the housing 1, and the emulsion is sheared by the shear blade 3. At this time, the deflection blade 32 is in the initial position, and the deflection blade 32 overlaps with the rectangular opening on the bottom blade 31, so that the deflection blade 32 and the bottom blade 31 form a complete blade surface, and the emulsion is stirred together, so that the emulsion is more delicate after passing through the filter plate 4; when there are agglomerated impurities that are not completely emulsified in the emulsion, the movable blade 33 and the bottom blade 31 are pressed by the emulsion and come close, the elastic member 34 is bent, and the protrusion 341 is driven to retract into the elastic member 34. At this time, Figure 5 In the state shown, the protrusion 341 is disengaged from the slot 321, and the deflection leaf 32 is not restricted and rotates under the action of the torsion spring to the termination position. The deflection leaf 32 at this position is staggered with the bottom leaf 31. Since the limiting slot 35 is provided on the bottom leaf 31, the deflection leaf 32 stops after rotating to a predetermined angle relative to the bottom leaf 31. The contact surface between the deflection leaf 32 and the impurity is inclined, so that the contact area is reduced. At this time, the rectangular opening is open, and the deflection leaf 32 at the termination position divides the agglomerated impurities, so that the divided impurities enter the rectangular opening through the upper and lower sides of the deflection leaf 32 respectively, to prevent the agglomerated impurities from exerting too much pressure on the shear blade 3 as a whole.

[0052] At the same time, when the deflection leaf 32 rotates to the end position, the position of the block 36 is fixed due to the restriction of the positioning groove 35. At this time, the block 36 on the rotating shaft is tangent to the tooth particle 51. At this time, the deflection leaf 32 is driven by the output shaft of the driving motor. Since the output torque direction of the driving motor is always positive, that is, clockwise, the block 36 is driven to rotate in the positive direction with the output shaft, thereby driving the sleeve 5 to rotate in the positive direction through the tooth particle 51, thereby driving the movable plate 41 to reciprocate up and down in the vertical direction; after the emulsion is discharged, when the deflection leaf 32 needs to be reset, the cover plate can be removed, and then The sleeve 5 can be rotated in the opposite direction by hand, and the block 36 can be driven to rotate in the opposite direction by the sleeve 5, so that the deflection leaf 32 returns to the initial position. At this time, since the emulsion is completely emptied, the movable leaf 33 is not affected by the pressure, and maintains a certain distance with the bottom leaf 31 under the elastic support of the elastic member 34, and the elastic member 34 is not bent by force, so that the protrusion 341 extends out of the elastic member 34 in the direction of the deflection leaf 32. When the deflection leaf 32 returns to the initial position, the slot 321 and the protrusion 341 are driven to engage with each other, so that the deflection leaf 32 overlaps the rectangular opening.

[0053] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
