Abstract
The utility model relates to a clamping device of a material containing bag containing scattered or granular material. The clamping device comprises a machine frame provided with clamping boards, where the clamping boards are arranged on the side of the hole wall of a discharging port in pairs. The machine frame connected with a power mechanism is hinged on a supporting seat, and the power mechanism drives the clamping boards of the machine frame to surround the discharging port to clamp a bag mouth of the material containing bag on the hole wall of the discharging port. The clamping device can enable the bag mouth of the material containing bag can to be firmly clamped on a position of the discharging port, and ensure that the bag mouth can not slide down from the discharging port during a discharging process. The whole clamping device is simple and convenient to operate, reliable and practical, and avoids the operation of artificial sustaining, thereby improving work efficiency.
Description
Technical field
The utility model relates to a kind of fixing device of the bag of feeding, and specifically relates to the fixing device of the charging bag of loose or granular material.
Background technology
Loose or powder and granule shape material adopts charging bag splendid attire, for example concrete materials often in transhipment.The large-sized concrete raw material plant is that components in certain proportion such as the cement of doing the state of mixing and sand are mixed; Stir back enforcement cast with transporting to the camp site behind the pocket splendid attire again,, can adorn one ton of material so this type of charging bag volume is bigger; And be that sack with the charging bag maintains the feed opening place at feed bin during sacked material to charging; All want the artificial sack that goes to maintain at when filling with substance at every turn like this, trouble very, and if the insecure meeting of maintaining make sack from the feed opening landing because of material in the bag is overweight; Cause material unrestrained, working environment is difficult to tidy up.
Summary of the invention
The purpose of the utility model provides a kind of fixing device that can securely the sack of charging bag be clamped in the feed opening place.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: a kind of fixing device is characterized in that: comprise frame, frame is provided with clamping plate; Clamping plate are arranged in pairs in the hole wall side of feed opening; Frame links to each other with actuating unit, and frame also is hinged on the bearing, and the clamping plate on the actuating unit drive chassis and the outer wall of feed opening become to surround or separate cooperation.
The beneficial effect of the utility model is: when the sack of the bag of will feeding is enclosed within the feed opening place; Start actuating unit, actuating unit drives frame and rotates around bearing, and frame drive clamping plate surround the charging bag sack of gripping sleeve at feed opening hole wall place to feed opening; Guaranteed that like this sack can be from the feed opening landing in the process of blanking; After installing material, the clamping plate on the actuating unit drive chassis separate with the outer wall of feed opening, thereby take the charging bag away.Whole fixing device is simple to operation, reliable and practical, has avoided manual work to maintain this operation, thereby has improved work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of fixing device; As shown in Figure 1, comprise frame 10, frame 10 is provided with clamping plate 20; Clamping plate 20 are arranged in pairs in the hole wall side of feed opening; Frame 10 links to each other with actuating unit 30, and frame 10 also is hinged on the bearing 40, and the clamping plate 20 on actuating unit 30 drive chassis 10 and the outer wall of feed opening become to surround or separate cooperation.Actuating unit 30 provides power; Driving frame 10 rotates around bearing 40; Frame 10 drive clamping plate 20 surround with the outer wall of feed opening or separate, and can be clamped in the blanking port place to guarantee blanking fashionable dress pocket sack, after material installs; Clamping plate on the actuating unit drive chassis separate with the outer wall of feed opening, thereby take charged charging bag away.
Further say; The frame 10 of said fixing device comprises the cross bar 11 of horizontal arrangement, and the two ends of cross bar 11 are fixedly connected on the bending part of L shaped bar 12, and the plane that L shaped bar 12 is constituted is vertical with the length direction of cross bar 11; The upper end of described L shaped bar 12 and bearing 40 are hinged; Between the lower end of the L shaped bar 12 of homonymy cylinder 30 is set, the upper end of the shaft of described cross bar 11 and pole 13 is connected, and the lower end of pole 13 respectively with the horizontal direction of clamping plate 20 on two ends be connected.In the charging process, cylinder 30 drives L shaped bar 12 and rotates around bearing 40, surrounds with the outer wall of feed opening or separates thereby drive cross bar 11, pole 13 and clamping plate 20, realizes maintaining and separating of charging bag and feed opening.With cylinder is that air-actuator satisfies the power needs, and responds fast because the needed power of whole device is little as the preferred version of actuating unit 30.
The bar mouth end of the transverse rod sections of the cylinder body tail end of cylinder 30 and the L shaped bar 12 of a side is hinged, and the rod end of the rod end of the transverse rod sections of the L shaped bar 12 of homonymy and the piston rod of cylinder 30 is hinged, can realize that so the L shaped bar 12 of air cylinder driven rotates around bearing 40.Bearing 40 can be the part of feed bin warehouse or the frame that supports the feed bin warehouse, also can be the independent rack unit that is provided with.Adopt the advantage of L shaped bar 12 to be that entire mechanism takes up room little, its pivot region is also little, and the cylinder length that can select for use simultaneously is also little, and expendable weight is also saved cost.
For realizing that the when filling with substance clamping plate 20 bag sack of will feed is clamped in feed opening hole wall place; Clamping plate 20 are set to circular arc; And the radius of curvature of circular arc is consistent with the radius of feed opening, and simultaneously clamping plate 20 are distributed in the perimembranous of feed opening symmetrically and evenly, can guarantee like this sack closely chuck at the feed opening place.
Two ends on clamping plate 20 horizontal directions are provided with cushion block 14, the lower ends of cushion block 14 and pole 13, and two cushion blocks 14 bonding surfaces against each other are provided with rubber pad 50.Set rubber pad 50 has played and has relaxed the effect of impacting, and can avoid in the process that clamps corresponding two cushion blocks 14 to bump against like this and cause damage fixing device, thus the service life of extension fixture.
