Description

Environment-friendly grab bucket

Technical Field

The utility model relates to the technical field of material grab buckets, in particular to an environment-friendly grab bucket.

Background

The double-flap grab bucket is a common material transportation device on a port bulk cargo wharf, but the double-flap grab bucket often has the condition of scattering materials in the process of grabbing materials and transporting the materials to a hopper. For example, in one case, the grab bucket is used for transporting bulk cargo to the funnel after grabbing the bulk cargo, because the material is in the process from rest to movement, the grab bucket has the characteristic of keeping the original movement characteristic, and meanwhile, due to the action of external wind force, the material leaks from the rear part of the grab bucket body. Under another condition, when the grab bucket grabs coal with higher humidity, the fluidity of the coal is poor, redundant materials cannot overflow from the rear part of the grab bucket in the grabbing process of the grab bucket, the grab bucket is caused to be incapable of being completely closed after the grab bucket is fully grabbed with the materials, and materials are leaked from the bottom edge and the side edge of the bucket body in the process of moving the grab bucket towards the funnel direction. The grab bucket has the condition of scattering materials in the process of transporting materials, so that certain economic loss can be brought to a wharf, and great pollution is caused to the surrounding environment.

The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.

Fig. 1 to 5 are schematic diagrams related to an environmental protection grab bucket provided by the utility model. The environment-friendly grab bucket provided by the utility model is a double-flap grab bucket, the double-flap grab bucket comprises two bucket flaps, namely a left bucket flap and a right bucket flap (or a first bucket flap and a second bucket flap), and the two bucket flaps in the grab bucket can grab materials (or goods) in a closed mode.

Referring to fig. 1 to 3, at least one through hole 9 is formed in at least one of the two bucket petals, and bucket covers 8 corresponding to each through hole 9 are rotatably connected to the outer side wall of at least one bucket petal, wherein each bucket cover 8 can shift relative to the outer side wall of the bucket petal so as to control whether the inner cavity of the bucket petal is communicated with the outside through the through hole 9.

In order to be able to quickly grasp, release and transport material smoothly during loading, transport and unloading, optionally at least one through hole 9 may be provided in both flaps.

It will be appreciated that at least one through hole 9 may be open on at least one bucket flap. By way of example, assuming that the two lobes comprise a left lobe and a right lobe, it is possible to provide at least one through hole 9 only on the left lobe; at least one through hole 9 can be formed only on the right bucket valve; at least one through hole 9 can be formed in the left bucket flap, and at least one through hole 9 can be formed in the right bucket flap.

In the embodiment of the present application, the number of the through holes 9 provided on at least one bucket may be set according to actual application requirements (for example, the size of the bucket). In addition, the number of the through holes 9 provided on different hopper petals may be the same or different, and the present application does not limit any limitation as to whether the number of the through holes 9 provided on at least one hopper petal and the number of the through holes 9 provided on each hopper petal are the same.

Correspondingly, the outer side wall of at least one bucket flap is rotatably connected with a bucket cover 8 corresponding to each through hole 9 respectively. That is, the number of through holes 9 provided on the flap may be the same as the number of caps 8. For example, assuming that the left bucket is provided with two through holes 9, two bucket covers 8 may be rotatably connected to the outer side wall of the left bucket, and the two bucket covers 8 respectively correspond to the two through holes 9.

Based on the possible embodiments, during the process of grabbing the material by the environmental protection grab, the material may squeeze the inner cavity of the bucket flap, so that part of the material overflows the bucket flap along the through hole 9, and the bucket cover 8 rotates on the outer side wall of the bucket flap due to the extrusion or overflow of the material, so that the inner cavity of the bucket flap is communicated with the outside through the through hole 9, and the material leaks out through the through hole 9; after the material spills, rotate the bucket lid 8 of connection on the bucket lamella lateral wall and can cover on the through-hole 9 that corresponds under self gravity effect for the inner chamber of bucket lamella is through-hole 9 and external non-intercommunication, has effectively avoided the problem of leaking the material in the follow-up material transportation.

Of course, in practical design, if the interval distance between the two through holes 9 is smaller than the preset distance, the two through holes 9 may also share one bucket cover 8; or two through holes 9 are directly communicated to form one through hole 9, and the bucket cover 8 corresponding to the communicated through hole 9 is rotationally connected on the outer side wall of the bucket valve.

In one example, the lid 8 may be pivotally connected to the outer side wall of at least one of the flaps by means such as a hinged or swivel connection. Referring to the enlarged view of the partial structure B on the bucket segments shown in fig. 2, the bucket cover 8 may be rotatably connected to the outer sidewall of the bucket segments by using a hinge structure, wherein a certain number (e.g., one, two or more) of hinge structures may be provided according to the size of the through hole 9 (and/or the size of the bucket cover 8), and the specific rotation connection manner of the bucket cover 8 is not limited in the present application.

It will be appreciated that the specific opening position of the at least one through hole 9 on the at least one bucket flap may be arbitrarily set. In order to avoid the environmental protection grab from scattering materials during the process of grabbing and transporting the materials, in the embodiment of the application, at least one through hole 9 can be arranged on one side of the grab valve far away from the ground (or the materials).

Specifically, referring to fig. 1 to 3, the body of each bucket flap may include a main steel pipe 1, a bucket bottom plate 6, a support bent plate 7, and side plates 2; a plurality of cover plate structures 3 are welded between the main steel pipe 1, the bucket bottom plate 6, the supporting bent plate 7 and the side plates 2 in a sealing mode, and through holes 9 are formed in one side, close to the cover plate structures 3, of the bucket bottom plate 6.

As shown in fig. 3, the body of the bucket flap may comprise two supporting bent plates 7 and two side plates 2, wherein the two supporting bent plates 7 and the two side plates 2 are welded on the bucket bottom plate 6 respectively, and at this time, three larger gaps exist in the upper part of the bucket flap body. In the embodiment of the present application, three cover structures 3 may be provided to close the three gaps, respectively.

It will be appreciated that at least one of the plurality of cover structures 3 may be a smooth plate-like structure, for example at least one cover structure 3 being a cuboid or square for directly connecting the bucket floor 6, the main steel duct 1, the support bend 7 and the side panels 2.

In an embodiment of the present application, at least one cover structure 3 of the plurality of cover structures 3 may further include four cover plates spliced into a pyramid shape. By arranging the cover plate structure 3 spliced into a pyramid shape, on one hand, the sealing of the grab bucket is enhanced, and the gap of the grab bucket at the upper part after closing is reduced. On the other hand heightens the bucket body to provide the activity space for the material of snatching in the grab bucket, avoid the material to carry out the in-process of extra extrusion to the grab bucket, lead to two lamella of grab bucket to open at the in-process of transporting the material and spill the hourglass material.

Alternatively, the number of through holes 9 provided on the bucket flaps may also be the same as the number of the plurality of cover plate structures 3. As an example and not by way of limitation, referring to fig. 1 and 3, three cover plate structures 3 may be sealed and welded between the main steel pipe 1, the bucket bottom plate 6, the support bent plate 7 and the side plates 2, and correspondingly, three through holes 9 may be provided on one bucket flap, and each through hole 9 is correspondingly provided with a bucket cover 8.

Through setting up through-hole 9 and the apron structure 3 that quantity is the same like this, can increase the fill lamella inner chamber space, increase the passageway that spills of material, avoid the material to carry out extruded in-process to the grab bucket, lead to two fill lamella to open at the in-process of transporting the material and spill the hourglass material. Simultaneously, through the through-hole 9 and the apron structure 3 that set up the quantity the same still can effectively solve the problem that the material is difficult to release because of the air between unable discharge material and the apron structure 3 inside wall is not enough set up to the through-hole 9 quantity.

Optionally, referring to fig. 1 and 3, a sealing plate 4 may be welded at the side edge of the side plate 2, and the sealing plate 4 is provided with a stop strip 5 at equal intervals; when the two bucket flaps are closed, the baffle strips 5 on the two bucket flaps are mutually meshed in a staggered mode, and the two bucket flaps form a closed space. In the embodiment of the application, the side edges of the two bucket petals are in staggered engagement through the barrier strips to form a labyrinth sealing structure, so that the leakage can be avoided when powdery materials (such as chemical fertilizers and small particles such as rapeseeds and wheat) are grabbed.

In summary, the environment-friendly grab bucket provided by the embodiment of the utility model can effectively avoid the problem of material leakage in the process of transporting materials, reduce the economic loss of a wharf and improve the environmental pollution of the wharf or a storage yard, and has the advantages of simple structure, low manufacturing cost and popularization value.

Optionally, gaps among four cover plates of the cover plate structure 3 are filled through welding, so that the tightness of the bucket body can be ensured.

Alternatively, the height of the cover structure 3 may be determined according to the stacking angle of the materials and the flow angle of the natural stacking.

Alternatively, the two bucket petals may include a first bucket petal and a second bucket petal, the stop strip 5 on the first bucket petal is disposed on a side of the corresponding sealing plate 4 facing the interior of the first bucket petal, and the stop strip 5 on the second bucket petal is disposed on a side of the corresponding sealing plate 4 facing the exterior of the second bucket petal.

Wherein the first bucket flap is a left bucket flap and the second bucket flap is a right bucket flap; or the first bucket is a right bucket and the second bucket is a left bucket. A schematic diagram of a blocking strip malocclusion scene may be shown in fig. 4.

The distance between the bars 5 may be set, for example, according to the material gripped. For example, to cope with most of the material with larger fluidity, smaller particles or powdery material, the spacing between the barrier strips 5 may be set to 25-35mm.

Optionally, the length and width of the sealing plate 4 can be determined according to the flowability and the material drop of the accumulated materials, so that the grab bucket can not be scattered and leaked under the condition that the grab bucket cannot be completely closed, the materials are sealed and completely sealed at the inner side of the grab bucket, and the scattering of the materials is prevented. For example, the length of the sealing plate may be set at 220-280mm.

In one example, as shown in fig. 5, the bottom edge of the bucket base plate 6 of the first bucket flap and the bottom edge of the bucket base plate 6 of the second bucket flap are mis-engaged.

Even if the left bucket flap and the right bucket flap form a plurality of materials (bulk goods) which are grabbed in the bucket body space, when the left bucket flap and the right bucket flap cannot be completely closed, the materials cannot fall off from the bottom edge of the bucket bottom plate 6 because of the dislocation compensation measures, and meanwhile, because of the dislocation structure of the bottom edge of the bucket bottom plate 6, the bucket radii of the left bucket flap and the right bucket flap are almost equivalent, so that no influence is caused on the cleaning operation of customers.

It is worth to say that, the environment-friendly grab bucket provided by the embodiment of the application is provided with the staggered engagement structures at the side cutting edge and the bottom cutting edge. Therefore, when the left bucket flap and the right bucket flap are difficult to close (for example, the materials are grabbed more or the materials cannot be accumulated upwards in the bucket body due to too high viscosity or humidity, and the bottom edge and the side edge cannot be completely closed tightly), the dislocation occlusion structures are arranged at the side edge and the bottom edge, so that the materials can be prevented from being scattered from the side edge and the bottom edge, the radius of the bucket bodies of the two bucket flaps is the same, and the cleaning operation at the tail end of the operation is completely unaffected.

With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
