Description

Technical Field

[0001] The utility model relates to the field of sorting devices, and particularly relates to a crayfish tail sorting device. Background Art

[0002] The protein content in crayfish is very high, and the meat is soft and easy to digest, which is a good food for people who are weak and need to recuperate after illness. Before the crayfish tails are processed, sorting is required. Sorting can ensure that crayfish tails of the same size are processed uniformly, improving efficiency. Generally, a sorting device with different sieves is used for sorting.

[0003] When the existing sorting device is in use, the sieve is fixed to the device by screws. When it is necessary to disassemble the sieve for corresponding operations, the screws need to be completely removed to achieve the disassembly work. The operation is time-consuming and laborious, which is not conducive to quick disassembly and installation. And during the sorting process, since the crayfish fall in an irregular rolling manner, there are prone to be some crayfish that are smaller than the sieve gap but do not pass through the sieve. Such crayfish are collected by the collection box at the bottom of the device for subsequent re-sorting. However, the collection box is often welded to the device and cannot be removed to pour out the crayfish tails, and the crayfish tails cannot be quickly taken out, and the operation takes a lot of time. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a crayfish tail sorting device, which can effectively solve the problems in the background art.

Detailed implementation manners

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0019] As Figures 1-4 shown, a crayfish tail sorting device includes a device main body 1. Inside the device main body 1, a first screen 2, a second screen 3 and a third screen 4 are sequentially arranged. Installation structures 5 are provided on the first screen 2, the second screen 3 and the third screen 4. A support frame 6 is connected to the device main body 1, and a collection structure 7 is connected to the end of the support frame 6. A first hopper 8, a second hopper 9 and a third hopper 10 are arranged at the lower end of the device main body 1, and the first hopper 8, the second hopper 9 and the third hopper 10 are respectively located below the first screen 2, the second screen 3 and the third screen 4. The support frame 6 is welded to the device main body 1, and an insertion hole is provided at the end of the support frame 6. The collection structure 7 includes a collection box 701, a handle 702, an insertion rod 703, a clamping groove 704 and a limit frame 705. The collection box 701 is fixedly connected to the handle 702. The insertion rod 703 is fixed inside the collection box 701, and the insertion rod 703 passes through the insertion hole on the support frame 6. The clamping groove 704 is arranged on the insertion rod 703, and the limit frame 705 is clamped in the clamping groove 704 on the insertion rod 703. The collection box 701 is connected to the support frame 6 through the insertion rod 703, and the collection box 701 can be quickly removed for pouring the crayfish tails. The limit frame 705 is installed on the insertion rod 703 through the clamping groove 704, and the limit frame 705 is used to play a limiting role to ensure the installation stability of the collection box 701.

[0020] When sorting the tails of crayfish using the device, the main body 1 of the device is stably placed through the support frame 6. The first sieve 2, the second sieve 3, and the third sieve 4 are fixed inside the main body 1 of the device through the installation structure 5. The first sieve 2, the second sieve 3, and the third sieve 4 respectively correspond to the first discharge hopper 8, the second discharge hopper 9, and the third discharge hopper 10 below. A collection structure 7 is provided at the end of the support frame 6. The tails of the crayfish are placed on the first sieve 2. The small tails pass through the first sieve 2 and are discharged from the first discharge hopper 8. The larger tails roll along the sieve. The medium-sized tails pass through the second sieve 3 and are discharged from the second discharge hopper 9. The large tails finally pass through the third sieve 4 and are discharged from the third discharge hopper 10. In this way, the sorting of the tails is achieved. During the sorting process, some tails may not pass through the corresponding sieve due to rolling too fast. These tails will eventually fall into the collection box 701 in the collection structure 7. When the number of tails in the collection box 701 is relatively large, the sorting work is paused. The limit frame 705 at the clamping groove 704 on the insertion rod 703 is removed, and the collection box 701 is pulled outwards so that the insertion rod 703 is detached from the support frame 6. The collection box 701 with the tails is lifted by the handle 702, and the tails are poured onto the unsorted tails. Then the collection box 701 is installed on the support frame 6. Under the action of the insertion rod 703 and the lower end of the collection box 701 abutting against the support frame 6, the collection box 701 has high stability. The limit frame 705 is installed in the clamping groove 704 for limiting, and then the sorting work of the tails can be continued.

[0021] Through the above implementation, the installation structure 5 is connected to the device main body 1. The installation structure 5 includes installation side plates 501, connection components 502 and installation bolts 503. The installation side plates 501 are connected to the connection components 502, and the connection components 502 are in contact with the upper end of the device main body 1. The installation bolts 503 pass through the connection components 502 and are connected to the device main body 1. The installation structure 5 further includes spring washers 504. The connection components 502 pass through the installation side plates 501, and the spring washers 504 are arranged on the connection components 502 and are in contact with the installation bolts 503. The connection components 502 include installation blocks 5021, stoppers 5022, U-shaped holes 5023, threaded holes 5024 and limit screws 5025. The installation blocks 5021 are fixedly connected to the stoppers 5022, and the installation blocks 5021 pass through the installation side plates 501. The U-shaped holes 5023 and the threaded holes 5024 are formed in the installation blocks 5021, and the limit screws 5025 are connected in the threaded holes 5024. The installation structure 5 is used to install the first screen 2, the second screen 3 and the third screen 4 respectively, so that the screens are detachable. The connection components 502 can move along the installation side plates 501 and cooperate with the installation bolts 503. It is not necessary to completely unscrew the installation bolts 503 to disassemble the screens, making the disassembly more convenient and facilitating the quick installation of the screens. The limit screws 5025 are arranged on the installation blocks 5021, and the limit screws 5025 play a limiting role to prevent the installation blocks 5021 from falling off the installation side plates 501.

[0022] During the installation of the screens, place the screens inside the device main body 1. The installation side plates 501 are in contact with the inner wall of the device main body 1. The installation blocks 5021 in the connection components 502 are in contact with the device main body 1, and at the same time, the stoppers 5022 are in contact with the installation side plates 501. Pass the end of the installation bolt 503 with the spring washer 504 through the U-shaped hole 5023, and use the installation bolt 503 to fix the installation block 5021, thus completing the fixation of the screens. When the device vibrates during use, under the action of the spring washer 504, the installation bolts 503 will not loosen, ensuring the use stability. When it is necessary to disassemble the screens, after loosening the installation bolts 503, pull the installation block 5021 so that the U-shaped hole 5023 on the installation block 5021 pulls the installation bolt 503, and then directly lift and remove the corresponding screen. In this process, it is not necessary to completely disassemble the installation bolts 503 for operation, which is convenient for the disassembly work of the screens and can also be quickly installed. The limit screws 5025 in the threaded holes 5024 play a limiting role to prevent the installation blocks 5021 from falling off the installation side plates 501, ensuring the relative stability.
