[0029] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0030] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, left, right" are usually defined by the direction of the drawing, and "inner" and "outer" refer to the inside and outside of the relevant parts. In addition, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0032] A grab bucket is a mechanism used to grab and release materials, which can realize the transfer of materials.

[0033] After grabbing materials, the existing fully enclosed environmental protection grab bucket tends to adhere to the outer top wall of the fully enclosed environmental protection grab bucket. During the movement of the fully enclosed environmental protection grab bucket, the adhered materials may be shaken off due to the vibration generated by the movement of the fully enclosed environmental protection grab bucket, causing the materials to be scattered everywhere, affecting the working environment. For example, in the fully enclosed grab bucket with patent number CN211594792U, a small amount of materials tends to adhere to the outer top wall of the fully enclosed environmental protection grab bucket, and then fall off as the fully enclosed environmental protection grab bucket moves, causing the materials to be scattered everywhere.

[0034] For this reason, Figure 1-Figure 4 As shown, one aspect of the present disclosure provides a fully enclosed environmentally friendly grab bucket, comprising a driving mechanism 1 and two bucket bodies 2 arranged opposite to each other.

[0035] The tops of the two bucket bodies 2 are hinged to each other, and the driving mechanism 1 is connected to the two bucket bodies 2. The driving mechanism 1 is used to drive the two bucket bodies 2 to move closer to and expand each other. A grabbing opening 21 is provided on the opposite side of the two bucket bodies 2. The tops, bottoms and sides facing away from each other of the two bucket bodies 2 are all constructed as closed structures, and the tops of the two bucket bodies 2 are set as an arc-shaped structure 22 protruding upward.

[0036] The two bucket bodies 2 are hinged to each other so that the two bucket bodies 2 can rotate relative to each other, so that when the two bucket bodies 2 are close to each other, they can grab materials, and when the two bucket bodies 2 are spread out, they can release materials. It can be understood that materials can enter the two bucket bodies 2 through the grabbing opening 21, and materials can fall from the two bucket bodies 2 through the grabbing opening 21. The materials can be coal, etc.

[0037] In the above technical solution, the top, bottom and opposite sides of the bucket body 2 are all constructed as closed structures, so that when the two bucket bodies 2 are brought close to each other, a closed space can be formed to accommodate materials, so that the materials are basically fully surrounded after being grabbed, and the materials will not overflow from the top of the bucket body 2 with the movement of the bucket body 2 and be scattered everywhere, thereby avoiding environmental problems and affecting the working environment. By setting the tops of the two bucket bodies 2 as an arc-shaped structure 22 protruding upward, the situation where the materials adhere to the outer top wall of the bucket body 2 can be reduced, and a small amount of materials can be prevented from adhering to the outer top wall of the bucket body 2, and then falling with the movement of the fully enclosed environmental protection grab, and being scattered everywhere, affecting the working environment.

[0038] Optionally, in one embodiment of the present disclosure, the two bucket bodies 2 each include a top plate 23, a bottom plate 24, and two oppositely arranged side plates 25, the two sides of the bottom plate 24 are connected to the bottoms of the two side plates 25, the two sides of the top plate 23 are connected to the tops of the two side plates 25, the ends of the top plates 23 of the two bucket bodies 2 that are separated from each other are respectively connected to the ends of the corresponding bottom plates 24 of the two bucket bodies 2 that are separated from each other to respectively enclose a receiving space, and the ends of the top plates 23 of the two bucket bodies 2 that are close to each other are respectively spaced from the ends of the corresponding bottom plates 24 of the two bucket bodies 2 that are close to each other to respectively form a grabbing opening 21. Such a setting can facilitate the bucket body 2 to form a closed space, and at the same time, leaving the grabbing opening 21, the grabbing and releasing of materials can be realized without interference. The top plate 23 is located above the bottom plate 24, and the two side plates 25 are located on both sides of the top plate 23 and the bottom plate 24. The top plate 23 and the bottom plate 24 are both arranged at an angle. In some examples, the bottom end of the top plate 23 is connected to the top end of the bottom plate 24, and the top end of the top plate 23 and the bottom end of the bottom plate 24 are arranged at intervals. The top plate 23, the bottom plate 24 and the two side plates 25 are enclosed to form a fan-shaped structure. In some examples, the top plate 23, the bottom plate 24 and the side plates 25 can be directly connected by welding.

[0039] Optionally, in one embodiment of the present disclosure, the top plate 23 is configured as an arc-shaped plate that bulges upward. That is, the top plate 23 is an arc-shaped plate, and the middle portion of the top plate 23 bulges upward, so that the outer top wall of the top plate 23 is arc-shaped. Since the arc-shaped structure 22 causes the material to adhere and affect the change in force, the material on the outer top wall of the top plate 23 is more likely to fall due to gravity, thereby reducing the problem of material adhesion on the outer top wall of the top plate 23. The arc-shaped plate bulges upward, which is the above-mentioned arc-shaped structure 22.

[0040] Optionally, in another embodiment of the present disclosure, the top outer wall of the top plate 23 is formed with an arc-shaped protrusion 26 protruding upward. The arc-shaped protrusion 26 can also generate an arc, so that the material is more easily affected by gravity and falls, which can reduce the problem of material adhesion on the outer top wall of the top plate 23. In some examples, the number of the arc-shaped protrusion 26 can be one, and the arc-shaped protrusion 26 can occupy the entire top of the top plate 23. The arc-shaped protrusion 26 is the arc structure 22.

[0041] Optionally, in one embodiment of the present disclosure, the outer surface of the top of the top plate 23 is covered with a first anti-stick coating 27. The first anti-stick coating 27 can further reduce the adhesion of the material to the outer surface of the top of the top plate 23, avoid the problem of the material scattering around, and does not affect the grasping and releasing of the material. In some examples, the first anti-stick coating 27 can be a ceramic coating, and the material can be coal, so that the adhesion of coal ash and the like can be effectively reduced. In some examples, the first anti-stick coating 27 covers the outer surface of the top of the top plate 23, and can also cover the outer surface of the arc-shaped protrusion 26.

[0042] Optionally, in one embodiment of the present disclosure, the bottom outer surface of the bottom plate 24 and the opposite sides of the two side plates 25 are covered with a second anti-stick coating 28. This arrangement can reduce the adhesion of materials to the outer wall of the bottom plate 24 and the outer wall of the two side plates 25, and can further avoid the problem of materials scattering everywhere, while not affecting the grasping and releasing of materials. In some examples, the second anti-stick coating 28 can be a ceramic coating, and the material can be coal, so that the adhesion of coal ash and the like can be effectively reduced.

[0043] Optionally, in one embodiment of the present disclosure, the fully enclosed environmentally friendly grab has an expanded state and a closed state. In the closed state, an overflow gap 3 is provided at one end where the top plates 23 of the two bucket bodies 2 are close to each other. In some examples, the overflow gap 3 is provided to discharge the air in the bucket body 2 and balance the air pressure when the two bucket bodies 2 are closed to grab the material, and to discharge the excess material grabbed, so as to facilitate the grabbing of the material. It should be noted that the width of the overflow gap 3 is relatively small, mainly for the overflow of excess material.

[0044] Optionally, in one embodiment of the present disclosure, the thickness of the top plate 23 is 4-6 mm, and the thickness of the bottom plate 24 and the side plate 25 is 10 mm-20 mm. The bottom plate 24 and the side plate 25 need to bear the weight of the material, and need a large thickness, while the top plate 23 mainly plays a sealing role, and needs a small thickness, which can reduce the overall weight of the bucket 2 and reduce the manufacturing cost. In some examples, the thickness of the top plate 23 can be 6 mm, and the thickness of the bottom plate 24 and the side plate 25 can be 15 mm.

[0045] Optionally, in an embodiment of the present disclosure, the driving mechanism 1 includes a first supporting base 11 , a second supporting base 12 , a transmission mechanism 13 and two connecting arms 14 .

[0046] One end of the two connecting arms 14 is hinged to the first supporting base 11, and the other end of the two connecting arms 14 is hinged to the two bucket bodies 2. The tops of the two bucket bodies 2 are hinged to the second supporting base 12. The first supporting base 11 is located above the second supporting base 12. The two ends of the transmission mechanism 13 are respectively connected to the first supporting base 11 and the second supporting base 12. The transmission mechanism 13 is used to connect to an external driver to drive the first supporting base 11 and the second supporting base 12 to move closer to or away from each other.

[0047] Among them, the two bucket bodies 2 can rotate relative to the second support base 12, and the connecting arm 14 plays a linkage role, which can limit the rotational freedom of the two bucket bodies 2 and realize the rotation of the two bucket bodies 2 in a specified direction. It can be understood that when the external driver drives the first support base 11 and the second support base 12 to move closer to each other through the transmission mechanism 13, the two bucket bodies 2 rotate due to the action of the connecting arm 14, and the two bucket bodies 2 can move closer to each other. When the external driver drives the first support base 11 and the second support base 12 away from each other through the transmission mechanism 13, the two bucket bodies 2 rotate due to the action of the connecting arm 14, and the two bucket bodies 2 can be unfolded. Through the unfolding and approaching of the two bucket bodies 2, the material can be grasped and released. In some examples, a connecting portion is formed on the top of the two bucket bodies 2, and the connecting portion is hinged to the second support base 12.

[0048] Optionally, in an embodiment of the present disclosure, the transmission mechanism 13 includes two rollers 131 and a rope 132 , the two rollers 131 are respectively connected to the first support base 11 and the second support base 12 , and the rope 132 is wound around the two rollers 131 .

[0049] The rope 132 is wound around two rollers 131, and the rope 132 can be connected to an external winding device, that is, the rope 132 can be wound and released. During the winding and releasing process of the rope 132, the two rollers 131 can rotate accordingly, maintaining the connection between the rope 132 and the two rollers 131, and not affecting the winding and releasing of the rope 132. It can be understood that when the rope 132 is wound, the distance between the two rollers 131 becomes smaller, that is, the first support base 11 and the second support base 12 are close to each other, and when the rope 132 is released, the distance between the two rollers 131 becomes larger, that is, the first support base 11 and the second support base 12 are away from each other.

[0050] A second aspect of the present disclosure further provides a ship unloader, comprising the above-mentioned fully enclosed environmentally friendly grab bucket.

Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0052] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0053] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
