Description
Technical Field
[0001] The utility model belongs to the technical field of breeding equipment and relates to a scale, in particular to a crab scale with a grabbing function. Background Art
[0002] During the crab farming process, crabs usually need to be weighed regularly to observe their growth signs. Currently, traditional electronic scales are mostly used for weighing. Since crabs are aggressive and difficult to catch, it is also difficult to fix them on the electronic scale after catching them, which makes the weighing process difficult to operate and even causes injuries to operators.
[0003] Therefore, it is necessary to provide a crab scale that is convenient for weighing. In the prior art, the utility model patent with publication number 207197645U discloses a special electronic scale for crabs, including a base, a display screen, a button group, a support column, a weighing platform, a storage box, a rotating cover plate, a customer observation screen, a support column sleeve, a pressure sensor, a block, a drainage groove and a water outlet. The same side of the base is provided with a display screen and a button group. The top of the base supports the weighing platform through the support column. A storage box is welded on the weighing platform. A rotating cover plate is hinged on the top of one side wall of the storage box. The lower surface of the rotating cover plate completely covers the top opening of the storage box. The electronic scale is welded with a storage box that does not count weight on the weighing platform, and the storage box is surrounded by a steel grid plate. A drainage groove and a water outlet are provided on the weighing platform. Therefore, when weighing live crabs, there is no need to add a rope to restrict the movement of live crabs. The water attached to the live crabs will also flow out from the water outlet along the drainage groove, which minimizes the gross weight of live crabs when weighing.
[0004] The device controls the range of crab movement on the electronic scale by setting up a holding box on the weighing platform to assist in weighing crabs. The device increases the accuracy of weighing to a certain extent, but there is still a risk of personal injury in the process of grabbing and placing crabs, and the weighing process is complicated and not suitable for use in breeding.
