Description
Technical Field
[0001] The utility model relates to the technical field of ship unloader hoppers, in particular to a weighing device for a ship unloader hopper. Background Art
[0002] The ship unloader hopper is an important device used in port ship unloading operations. It is usually used in conjunction with a grab ship unloader. The grab ship unloader grabs materials from the ship with a grab, then unloads the materials into the hopper, and then the hopper transports the materials to the subsequent transportation system or storage facility. The structure and design of the hopper have an important impact on improving the ship unloading efficiency, reducing material loss, and extending the service life of the equipment.
[0003] When the existing hopper is loaded, the weight of the materials in the hopper cannot be known, and only the capacity of the hopper can be used for judgment. However, such judgment often results in inaccurate situations, which may cause the materials inside the hopper to be too heavy and subsequently affect the unloading efficiency.

Detailed implementation manner
[0021] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0022] Please refer to Figures 1-4 , a weighing device for a ship unloader hopper of the present utility model includes a hopper body 1 and a base 2. The hopper body 1 is the ship unloader hopper, which is used to collect and weigh materials. The base 2 is the bottom structure of the device, which is used to support the ship unloader hopper and install other structures. Four support columns 22 are arranged on the outer side above the base 2, that is, the hopper body 1 is supported by the support columns 22. Movable openings 21 are arranged on the front two support columns 22, and movable bolts 12 are arranged on both sides in front of the hopper body 1. That is, the movable bolts 12 are connected to the movable openings 21, so that the support columns 22 support the front of the hopper body 1. Support grooves 23 are arranged on the rear two support columns 22, and support blocks 13 are arranged on both sides behind the hopper body 1. The support blocks 13 are butted against the support grooves 23. By the movement of the movable bolts 12 on the movable openings 21, the two support blocks 13 at the rear side are located on the support grooves 23, so as to support the rear side of the hopper body 1.
[0023] A weighing block 11 is arranged on the inner side behind the hopper body 1, and an installation frame 3 is arranged on the inner side behind the base 2. The installation frame 3 is an installation structure. An installation plate 4 is arranged above the inner side of the installation frame 3. The installation plate 4 is an installation structure. The installation plate 4 includes a weighing plate 41. The weighing block 11 is located on the weighing plate 41. That is, the weight of the hopper body 1 is pressed onto the weighing plate 41 by the weighing block 11, so as to weigh it, that is, to obtain the weight of the materials. A limit opening 33 is arranged below the inner side of the installation frame 3, and a limit bolt 5 is arranged inside the limit opening 33. The limit bolt 5 is connected to the limit opening 33 and the limit bolt 5 moves inside the limit opening 33. A threaded rod 53 is arranged at the top of the limit bolt 5, and a threaded pipe 43 is arranged at the bottom of the installation plate 4. The threaded rod 53 is in threaded connection with the threaded pipe 43. That is, the limit bolt 5 rotates in the limit opening 33, which drives the threaded rod 53 to rotate, thereby pushing the installation plate 4 and the weighing plate 41 at the top to rise, so as to lift the weighing block 11 and make the support blocks 13 on both sides leave the support grooves 23.
[0024] On both sides inside the installation frame 3, there are provided limiting rails 32. On both sides of the installation plate 4, there are provided limiting blocks 42. The limiting blocks 42 are movably connected to the limiting rails 32. At the bottom of the limiting bolt 5, there is provided a first bevel gear 51. Outside the first bevel gear 51, there is provided a second bevel gear 52. The second bevel gear 52 meshes with the first bevel gear 51. At the rear side of the base 2, there is provided a motor 31. The motor 31 is connected to the second bevel gear 52. That is, the motor 31 drives the second bevel gear 52 to rotate, thereby driving the first bevel gear 51 to rotate, so that the limiting bolt 5 rotates in the limiting port 33. By limiting the limiting block 42 through the limiting rail 32, the installation plate 4 is kept stable when ascending and descending.
[0025] The working principle of the present utility model is as follows: The device is connected to the movable port 21 through the movable bolt 12, so that the support column 22 supports the front of the hopper body 1. By the movable bolt 12 moving on the movable port 21, the two support blocks 13 at the rear side are on the support grooves 23, so as to support the rear side of the hopper body 1. When weighing is required before feeding, the motor 31 drives the second bevel gear 52 to rotate, thereby driving the first bevel gear 51 to rotate, so that the limiting bolt 5 rotates in the limiting port 33, that is, drives the threaded rod 53 to rotate, thereby pushing the installation plate 4 and the weighing plate 41 at the top to rise. By limiting the limiting block 42 through the limiting rail 32, the installation plate 4 is kept stable when ascending and descending, jacking up the weighing block 11, so that the support blocks 13 on both sides leave the support grooves 23. The weight of the hopper body 1 is pressed onto the weighing plate 41 through the weighing block 11, so as to weigh it.
[0026] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
