Description

Technical Field

[0001] The utility model belongs to the technical field of transport hoppers, and in particular relates to a ferroboron dustproof transport hopper. Background Art

[0002] Ferroboron is an alloy material, the main components of which are iron and boron. The main function of ferroboron is to enhance the hardness, strength and toughness of steel, making it more wear-resistant, heat-resistant and corrosion-resistant. In addition, ferroboron can also promote uniform grain refinement inside steel and improve the processing performance of steel.

[0003] At present, during the production process of ferroboron raw materials, the materials need to be transported through a transport hopper. When the transport hopper leaves the feeding end, the upper opening of the hopper is exposed, and dust in the materials is easily released during the transportation process, thereby polluting the working environment. The existing method is to weld an oblique baffle above the hopper to reduce the opening size of the hopper. Although this method can reduce the scope of dust overflow, the hopper opening is always kept open, so the actual dust suppression effect of this method is poor. Therefore, there is an urgent need for a ferroboron dust-proof transport hopper to solve the above problems. Utility Model Content

[0004] In view of the problem that the opening of the existing hopper is always kept in an open state and the ordinary baffle structure has a poor dust suppression effect, the present utility model is proposed.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a ferroboron dust-proof transport hopper, comprising a hopper body and a flip cover, a telescopic dust-proof mechanism is installed at the opening of the hopper body, one end of the telescopic dust-proof mechanism is connected to two counterweights, and the other end is connected to a cross bar, and the side of the hopper body away from the flip cover is slidably connected to two push rods, and the push rods are transmission-connected to the cross bar; the telescopic dust-proof mechanism includes a limit plate fixedly connected to the symmetrical sides of the hopper body, a plurality of slide rods are slidably connected between the limit plate and the hopper body, and a dust-proof cloth is fixedly connected between two adjacent slide rods.

[0006] Furthermore, a sliding rod away from one side of the flip cover is connected and fixed to the limiting plate.

[0007] Furthermore, the counterweight block is connected to a slide bar close to a side of the flip cover via a pull rope 1, and a limiting guide rail 1 is slidably connected to the counterweight block, and the limiting guide rail 1 is fixedly connected to the hopper body.

[0008] Furthermore, both ends of the cross bar are connected to the sliding rod close to the flip cover through a second pull rope, and both ends of the cross bar are slidably connected to a second limiting guide rail, the second limiting guide rail is fixedly connected to the hopper body, and the cross bar and the top rod are connected through a driving assembly.

[0009] Furthermore, the driving assembly includes a rack fixedly connected to one end of the top rod, one side of the rack is meshed with a gear, the gear is rotatably connected to the hopper body, and a rotating rod 1 is fixedly connected to the gear, one end of the rotating rod 1 is rotatably connected to the rotating rod 2, and the rotating rod 2 is hinged to the cross bar.

[0010] Furthermore, both ends of the limit plate are fixedly connected with guide rods, and the pull rope 1 and the pull rope 2 are in sliding contact with the guide rods.

[0011] Beneficial effects of the utility model:

[0012] 1. The utility model can slide on the opening end of the hopper body through the cooperation of the sliding rod and the dustproof cloth. When the top rod drives the cross rod to descend, multiple sliding rods slide to one side to open the opening of the hopper body; when the counterweight block descends, multiple sliding rods slide in the opposite direction to close the opening of the hopper body, and the dustproof effect is good.

[0013] 2. In the utility model, when the hopper body approaches the feeding end, the top rod abuts against the feeding end to drive the cross bar down, and the telescopic dust-proof mechanism contracts. After the top rod cancels the abutment with the feeding end, the telescopic dust-proof mechanism is driven to expand under the gravity of the counterweight block. No external power is required, the structure is compact, and it is conducive to popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. Example

[0020] Reference Figures 1 to 3 , which is the first embodiment of the utility model, provides a ferroboron dustproof transport hopper, which includes a hopper body 1 and a flip cover 2. A telescopic dustproof mechanism 3 is installed at the opening of the hopper body 1. One end of the telescopic dustproof mechanism 3 is connected to two counterweights 4, and the other end is connected to a cross bar 6. The side of the hopper body 1 away from the flip cover 2 is slidably connected to two push rods 7, and the push rods 7 are transmission-connected to the cross bar 6.

[0021] In the above technical scheme, under the action of gravity of the counterweight block 4, the telescopic dust-proof mechanism 3 is unfolded, which can completely cover the opening of the hopper body 1 to prevent dust from being dispersed when the hopper body 1 is transporting ferroboron materials. When the top rod 7 drives the cross bar 6 to descend, the cross bar 6 can drive the telescopic dust-proof mechanism 3 to open, so that the opening of the hopper body 1 is opened to facilitate contact with the material.

[0022] In actual work, a plurality of lifting ears are fixedly welded on the hopper body 1 , and the movement of the hopper body 1 is controlled by connecting the lifting ears with lifting equipment.

[0023] The telescopic dustproof mechanism 3 includes a limit plate 301 fixedly connected to two symmetrical sides of the hopper body 1 , a plurality of slide bars 302 are slidably connected between the limit plate 301 and the hopper body 1 , and a dustproof cloth 303 is fixedly connected between two adjacent slide bars 302 .

[0024] In the above technical solution, the dustproof cloth 303 is made of flexible rubber material and can be bent and deformed. When multiple slide bars 302 are unfolded at equal intervals, the dustproof cloth 303 can be driven to unfold synchronously, thereby covering the opening of the hopper body 1 to prevent the material dust in the hopper body 1 from floating out. When the multiple slide bars 302 shrink and approach each other, the dustproof cloth 303 bends and folds to expose the opening of the hopper body 1 to facilitate receiving materials.

[0025] A slide bar 302 away from one side of the flip cover 2 is connected and fixed to the limit plate 301. After the slide bar 302 is connected and fixed to the limit plate 301, the slide bar 302 farthest from the slide bar 302 can make the dustproof cloth 303 unfold to block and then bend and fold when sliding.

[0026] The counterweight block 4 is connected to the slide bar 302 close to the side of the flip cover 2 through a pull rope 5, and the counterweight block 4 is slidably connected to a limiting guide rail 401, and the limiting guide rail 401 is fixedly connected to the hopper body 1. The gravity of the counterweight block 4 is greater than the sum of the sliding friction of the telescopic dustproof mechanism 3 and the gravity of the cross bar 6 and the top rod 7, so that when the top rod 7 is not affected by external force, the counterweight block 4 descends in the limiting guide rail 401, and drives a slide bar 302 to slide through the pull rope 5, and multiple slide bars 303 slide toward the side of the flip cover 2 and drive the dustproof cloth 303 to unfold, thereby covering the opening of the hopper body 1.

[0027] Both ends of the cross bar 6 are connected to the sliding rod 302 close to the flip cover 2 through a pull rope 8, and both ends of the cross bar 6 are slidably connected to the limiting guide rail 601, the limiting guide rail 601 is connected and fixed to the hopper body 1, and the cross bar 6 and the top rod 7 are connected through a driving assembly 9.

[0028] When the hopper body 1 is close to the feeding end, the top rod 7 abuts against the feeding end to drive the cross bar 6 to descend along the limiting guide rail 2 601. The cross bar 6 drives a slide bar 302 to slide through the pull rope 2 8, so that multiple slide bars 302 slide to one side of the cross bar 6 and the dustproof cloth 303 is bent and folded, so that the hopper body 1 opens.

[0029] Both ends of the limiting plate 301 are fixedly connected with guide rods 10, and the pull rope 1 5 and the pull rope 2 8 are in sliding contact with the guide rods 10. The multiple guide rods 10 limit the pull rope 1 5 and the pull rope 2 8 respectively, so that the pull rope 1 5 and the pull rope 2 8 can drive the sliding rod 302 to move after turning.

[0030] During use, when the lifting equipment drives the hopper body 1 to move toward the feeding end, the top rod 7 abuts against the feeding end and drives the cross bar 6 to descend. The cross bar 6 drives the sliding bar 302 connected to it to slide through the pull rope 8. At this time, multiple sliding bars 302 all slide to the side of the cross bar 6, and bend and fold the dustproof cloth 303 to make the hopper body 1 open. Then the feeding end can discharge ferroboron material into the hopper body 1. When the lifting equipment drives the hopper body 1 away from the feeding end, the top rod 7 cancels the abutment with the feeding end, and the counterweight block 4 descends under the action of gravity, and drives the sliding bar 302 connected to it to slide through the pull rope 5. At this time, multiple sliding bars 302 all slide to the side of the flip cover 2, and straighten and unfold the dustproof cloth 303 to block the opening of the hopper body 1 and prevent dust in the material from overflowing. Example

[0031] Reference Figure 4, which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the driving assembly 9 includes a rack 901 fixedly connected to one end of the top rod 7, a gear 902 is meshedly connected to one side of the rack 901, the gear 902 is rotatably connected to the hopper body 1, and a rotating rod 1 903 is fixedly connected to the gear 902, one end of the rotating rod 1 903 is rotatably connected to the rotating rod 2 904, and the rotating rod 2 904 is hinged to the cross bar 6.

[0032] In the above technical solution, the rotating rod 1 903 and the rotating rod 2 903 are arranged in a V shape, and the two sets of rotating rods 1 903 and rotating rods 2 904 are arranged symmetrically. When the top rod 7 descends, the rack 901 drives the gear 902 to rotate, and the gear 902 drives the rotating rod 1 903 connected thereto to rotate. The rotating rod 1 903 and the rotating rod 2 904 cooperate to drive the cross bar 6 to descend.

[0033] In actual work, by utilizing the rotational coordination of the rack 901 and the gear 902, the small-distance displacement of the top rod 7 can be amplified, and the cross bar 6 can be lifted and slid over a large distance, which is beneficial for the telescopic dustproof mechanism 3 to be quickly deployed and the working flexibility of the telescopic dustproof mechanism 3 is improved.

[0034] The remaining structures are the same as those of Example 1.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
