When using, the flexible end of patting cylinder 71 is reciprocal flexible, because the downside of patting plate 72 articulates in support 4, can make the upper portion of patting plate 72 towards ton bag reciprocating rotation and reciprocal the patting ton bag to make the inside powder of ton bag can comparatively more thorough discharge, optimize the result of use.

Referring to fig. 1 and 2, smuggle device 6 secretly includes two 62 of centre gripping subassembly of fixed connection in the discharging pipe 61 of support 4 and being used for centre gripping ton bag discharge end, and discharging pipe 61 is vertical setting and its lower part is frustum column structure, and the lower extreme of discharging pipe 61 is tip open structure to can do the buffering and slow down the raise dust when being used for making the ejection of compact.

Two 62 of centre gripping subassemblies are including setting up in the grip ring 621 and the lock ring 622 of cover locating discharge pipe 61 on discharge pipe 61 upper end opening border, discharge pipe 61, grip ring 621 and lock ring 622 with the central axis, grip ring 621 and lock ring 622 through a plurality of connecting rod fixed connection that encircle both settings, grip ring 621 slides through the connecting rod and connects in discharge pipe 61, grip ring 621 can the butt in the upper end opening border of discharge pipe 61. The locking ring 622 is provided with a locking piece 623 used for enabling the locking ring to slide and lock, the locking piece 623 can be selected from a commercially available hasp, the side part of the discharge pipe 61 is fixedly connected with a dust suppression pipe 611 communicated with the discharge pipe, and the dust suppression pipe 611 can be communicated with the dust remover.

So that the ton bag wear to locate the light ring valve after, the discharge end infiltration of ton bag is to the discharging pipe 61 in to make the part area face of ton bag discharge end by the centre gripping between the last opening border of grip ring 621 and discharging pipe 61, then move down through lock ring 622 and grip ring 621 and press from both sides the part area face with ton bag discharge end tightly, and make through lock 623 lock ring 622 and grip ring 621 slide the locking can, so that use.

Referring to fig. 1 and 2, an elastic tube 624 is disposed between the clamping ring 621 and the discharge tube 61, the elastic tube 624 has a ring-shaped central axis and has a ring-shaped structure having a central axis identical to that of the clamping ring 621 and the discharge tube 61, and the elastic tube 624 is fixedly connected to an upper opening edge of the clamping ring 621 or the discharge tube 61. So that the area face of ton bag can be comparatively inseparable be centre gripping relatively to for locking member 623 locking ring 622 provides certain buffering allowance, optimize result of use.

Referring to fig. 3 and 4, the aperture valve includes that the valve body 1 that is tubulose, a plurality of centre gripping subassemblies 2 and a plurality of driving piece 3 that are used for centre gripping ton bag discharge end, and a plurality of centre gripping subassemblies 2 are located the valve body 1 inboard and encircle the central axis setting of valve body 1, and the discharge gate of ton bag can be worn to locate valve body 1, and driving piece 3 is provided with the flexible end that can reciprocate flexible. Wherein, driving piece 3 fixed connection is in the outer wall of valve body 1, and the flexible end of driving piece 3 penetrates to the inboard of valve body 1.

The first clamping assembly 2 comprises two claw buckles 21 for clamping the ton bag and two push rods 22. The one end of two push rods 22 all articulates in the flexible end of driving piece 3, and the one end that driving piece 3 was kept away from to two push rods 22 articulates respectively in two claws 21 and keeps away from valve body 1 center one side, and driving piece 3 is located push rod 22 and keeps away from valve body 1 center one side, and push rod 22 is located its articulated claw 21 and keeps away from valve body 1 center one side. Wherein, the claw buckle 21 is hinged on the valve body 1.

The part of the claw buckle 21 far away from the push rod 22 and the valve body 1 can clamp the discharge hole of the ton bag, the plane where the curves of the rotating paths of the push rod 22 and the claw buckle 21 are located is parallel to the radial plane of the valve body 1, and the positions of the two push rods 22 hinged to the two claw buckles 21 are located in the middle of the positions of the two claw buckles 21 hinged to the valve body 1.

When the clamping device is used, when a ton bag needs to be clamped, only the telescopic ends of the driving pieces 3 need to extend out, so that the two push rods 22 hinged with the driving pieces 3 are opened, and the two claw buckles 21 are pushed to rotate towards the central position of the valve body 1, so that the parts, penetrating through the valve body 1, of the ton bag are clamped by the claw buckles 21, or the caliber of a discharge port of the ton bag is reduced, and the closing or flow control is performed; when the telescopic end of the driving piece 3 needs to be retracted, the telescopic end is opened.

Referring to fig. 3 and 4, the opening edges at two axial ends of the valve body 1 are fixedly connected with connecting flanges 11 which are the same with the opening edges at the central axis, and the first clamping assembly 2 is located between the two connecting flanges 11.

Referring to fig. 5, the jaw latch 21 includes a hinge pipe 211 and a latch lever 212 fixedly coupled to an outer wall of the hinge pipe 211, a central axis of the hinge pipe 211 being parallel to a central axis of the valve body 1, and an axis along which the latch lever 212 extends being parallel to a radial plane of the hinge pipe 211. One end of the push rod 22 far away from the driving piece 3 is hinged to the buckling rod 212, and the hinged pipe 211 is hinged to the two connecting flanges 11 or the inner wall of the valve body 1 through a screw rod and the like penetrating through the hinged pipe.

So that when using, do protection and isolation to clamping component 2 through two flange 11, when doing the centre gripping to the ton bag, push rod 22 returns to promote detain pole 212 make detain pole 212 drive the articulated pipe 211 circumferential direction of connecting can to make the whole comparatively stable of claw 21 during the use, optimize the result of use.

Referring to fig. 3 and 4, the two connecting flanges 11 are detachably connected to cover plates 111 at opposite sides respectively, the cover plates 111 may be fixedly connected to the connecting flanges 11 through bolts, and the separated connecting flanges 11 may be welded to the valve body 1 after the first clamping assembly 2 is installed. So as to protect the valve body 1 and the components inside the valve body 1 when in use.

The valve body 1 can be detachably connected to a plurality of fixed beams 12 on the lower side of the connecting flange 11 and fixedly connected to the support 4, the fixed beams 12 can be fixedly connected to the connecting flange 11 through bolts, and two ends of the fixed beams 12 are fixedly connected to the support 4.

The latch rods 212 of different claws 21 are fixedly connected to different positions of different hinge tubes 211 in the axial direction. To reduce the likelihood of interference between different buckling bars 212 during use.

Referring to fig. 6, in order to accommodate the buckling rods 212 connected to different axial positions of the hinge tube 211, the push rod 22 includes two connecting portions and a bending portion located between the two connecting portions, the two connecting portions are parallel to the connecting flange 11 after being installed, the two connecting portions are located in two planes parallel to each other, and two ends of the bending portion are integrally formed on or fixedly connected to opposite end edges of the two connecting portions. So that the push rod 22 can accommodate the snap rods at different axial positions of the hinge tube 211.
