[0002] A grab bucket refers to a special tool for a crane to grab dry bulk goods. It consists of two or more closable bucket-shaped jaw plates that form a material-containing space together. When loading, the jaw plates are closed in the material pile, and the material is grabbed into the material-containing space. When unloading, the jaw plates are opened in a suspended state above the material pile, and the material falls on the material pile. The opening and closing of the jaw plates are generally controlled by the wire rope of the crane's hoisting mechanism. Grab bucket operation involves no heavy physical labor, can achieve high loading and unloading efficiency and ensure safety, and is the main dry bulk cargo loading and unloading tool in ports. According to the types of goods handled, it can be divided into ore grab buckets, coal grab buckets, grain grab buckets, wood grab buckets, etc.

[0003] When the grab bucket grabs bulk materials, when the bulk materials are piled up in large quantities, during the process of grabbing and transferring them, the bulk materials are likely to scatter. The scattered materials are likely to pose a safety hazard to the staff at the bottom of the moving path. When the scattered amount is small, the remaining bulk materials are scattered around and are difficult to be grabbed by the grab bucket. Moreover, when the grab bucket grabs some wet and sticky materials, the materials stick to the grab bucket and are difficult to clean.

[0021] The following is a description of the preferred embodiments of the present utility model in conjunction with the attached drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0022] Embodiment: As Figures 1 to 3 shown, a large - capacity seven - petal grab bucket that is convenient for grasping according to the present utility model includes seven bucket petals 1. The seven bucket petals 1 are all hinged on the connecting column 5, and the connecting column 5 is located in the middle of the seven bucket petals 1; the top surface of the connecting column 5 is fixedly connected with a mounting column 4, and the sides of the mounting column 4 are respectively hinged with seven hydraulic cylinders 3. The telescopic ends of the hydraulic cylinders 3 are respectively hinged with the top surfaces of the seven bucket petals 1; by the telescopic movement of the hydraulic cylinders 3, the bucket petals 1 are driven to move, so as to realize the opening and closing of the bucket petals 1, and further facilitate the grasping of materials by the bucket petals 1.

[0023] The top surface of the mounting column 4 is fixedly connected with a top plate 6, and a plurality of fixed hooks 7 are installed on the top plate 6; the fixed hooks 7 are used to connect with the existing fixed ropes, and the seven - petal grab bucket is lifted and moved through the fixed ropes, so as to complete the transfer of materials.

[0024] An air cylinder 8 is installed in the connecting column 5, and the telescopic end of the air cylinder 8 is fixedly connected with a cover plate 9. The cover plate 9 is located in the middle of the seven bucket petals 1; the air cylinder 8 can drive the cover plate 9 to move. During the process of grasping materials, the cover plate 9 is in the original position. After the materials are grasped, the air cylinder 8 pushes the cover plate 9 downward, so that the cover plate 9 fits on the surface of the materials, covering the materials to prevent the materials from falling and causing safety accidents; when the materials are less and scattered around, the cover plate 9 can be used to scrape the materials together, so as to facilitate grasping. When scraping, it needs to be completed in combination with external existing equipment, such as the lifting equipment for transferring materials.

[0025] One side of the bucket flap 1 facing the cover plate 9 is installed with a scraping plate 10, and a tipping plate 2 is installed on the bottom surface of the bucket flap 1 facing the middle position. The tipping plate 2 is arranged to incline upwards, and when the bottoms of the seven bucket flaps 1 are closed, a sealing structure is formed, and the tipping plate 2 is located inside the seal. The setting of the tipping plate 2 makes it more convenient to grab the material.

[0026] The bottom surface of the mounting column 4 is provided with a mounting groove, the bottom surface of the connecting column 5 is vertically penetrated with a cavity, and the cavity is connected to the mounting groove, and the fixed end of the air cylinder 8 is installed in the mounting groove.

[0027] The bucket flap 1 is arc-shaped, and the middle part protrudes towards the side away from the cover plate 9, and the cover plate 9 is located above the protruding part of the bucket flap 1. By setting the protruding part, the quantity of the grabbed material can be increased, thus improving the efficiency.

[0028] The cover plate 9 is an arc-shaped structure symmetrical front and back, and the left and right ends of the cover plate 9 are at different heights, and inclined surfaces are respectively arranged on the bottom surfaces of the left and right ends of the cover plate 9. By setting different heights, the cover plate 9 is convenient for scraping and conveying the scattered material.

[0029] The scraping plate 10 is arranged to fit the side wall of the bucket flap 1, a fixing groove is opened on the side wall of the bucket flap 1, a spring 15 is installed in the fixing groove, and both ends of the spring 15 are respectively arranged on the groove wall of the fixing groove and the top surface of the scraping plate 10. When cleaning is required, the scraping plate 10 can be pulled to move along the surface of the bucket flap 1 to scrape off the stains, and the connected spring 15 prevents the scraping plate 10 from falling during the process of moving the scraping plate 10.

[0030] Two clamping grooves two 13 are respectively opened on the two side walls of the fixing groove, an elastic protection plate 16 is arranged on the surface of the fixing groove, both ends of the protection plate 16 are respectively connected with a clamping plate 14, and the clamping plate 14 is clamped in the clamping groove two 13, and a protruding part is arranged on the surface of the clamping plate 14 at one end. The protection plate 16 can play a protective role for the fixing groove during the process of grabbing the material, and the protruding part is convenient for removing the protection plate 16.

[0031] Two clamping grooves one 11 are symmetrically opened on the bottom surface of the bucket flap 1 where the scraping plate 10 is located, a clamping block 12 is clamped in the clamping groove one 11, and the clamping block 12 extends outside the clamping groove one 11. When the clamping block 12 is inserted into the clamping groove one 11, it can play a limiting role for the scraping plate 10, and the clamping block 12 extending to the outside is convenient for taking the clamping block 12.

[0032] During operation, through the arranged cover plate 9, under the push of the air cylinder 8, it can be attached to the top surface of the material to cover it after grabbing the material, preventing the material from falling during the transfer process. When the material is less and scattered around and difficult to grab, through the side end of the cover plate 9, the material can be scraped towards the middle along the ground to pile it up for convenient grabbing; a scraping plate 10 is arranged on the bucket flap 1, and when cleaning the bucket flap 1, by pushing the scraping plate 10 to move, the stains on the bucket flap 1 can be cleaned.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
