Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a frozen bullfrog preservation device. Background Art

[0002] Bullfrogs are amphibians belonging to the family Ranidae. They are native to the eastern part of Los Angeles, USA. Due to their large size and high economic value, they are widely introduced for breeding. Bullfrogs have become one of the main products of special aquaculture in my country. Bullfrogs are soft, tender, delicious and nutritious. They are high in protein, low in fat and cholesterol, and are very popular among consumers.

[0003] The bullfrog is transferred to the liquid nitrogen freezing device through the conveying roller for freezing and preservation. During the transportation of the bullfrog, the liquid nitrogen quick freezer sprays gas to freeze the bullfrog. However, only one side of the bullfrog is in contact with the liquid nitrogen gas, so the freezing speed of the other side of the bullfrog will be relatively slow, which may cause uneven temperature on the upper and lower sides of the bullfrog, thereby affecting the freezing and preservation effect of the bullfrog. Therefore, it is necessary to design a frozen bullfrog preservation device. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides the following technical solutions: a frozen bullfrog preservation device, comprising a freezing device body, the rear inner wall of the freezing device body is rotatably connected with a conveying roller for conveying bullfrogs, a liquid nitrogen quick-freezing machine for freezing bullfrogs is fixedly arranged on the top inner wall of the freezing device body, and a plurality of straightening mechanisms for changing the posture of bullfrogs are fixedly arranged on the rear inner wall of the freezing device body and located above the conveying roller;

[0005] The inner wall at the rear side of the main body of the freezing device is slidably provided with a turning mechanism for ejecting the bullfrog and turning it sideways, and is located at the lower side of the conveying roller.

[0006] As an improvement of the above technical solution, the straightening mechanism includes a horizontal fixing plate, which is fixedly installed on the rear inner wall of the refrigeration device body and located on the upper side of the conveying roller. An arc straightening plate for changing the conveying angle of the bullfrog is welded to the bottom of the horizontal fixing plate. An anti-stuck block is fixedly installed on the bottom of the refrigeration device body and located on the rear side of the arc straightening plate. The bullfrog is straightened and positioned separately during the conveying process of the conveying roller through the cooperation between the straightening mechanisms.

[0007] As an improvement of the above technical solution, the flipping mechanism includes an installation slot, and an installation slot is opened on the inner wall of the rear side of the freezing device body and located at the lower side of the conveying roller. The installation slot is movably connected with a moving block, and the front end of the moving block is fixedly installed with a power-assisted moving plate, and a plurality of push plates are welded on the top of the power-assisted moving plate. A plurality of arc push blocks for ejecting and flipping the bullfrog are fixedly installed on the top of the push plate. A power motor is detachably installed on the rear side surface of the freezing device body, and the front end of the power motor passes through the inner wall of the rear side of the freezing device body and extends into the inner side of the freezing device body. An elliptical power block for pushing the arc push block to move upward is fixedly installed on the output end of the power motor, and the outer side of the elliptical power block contacts the bottom of the power-assisted moving plate, and the bullfrog is ejected during the transportation process between the flipping mechanisms to cause the bullfrog to flip over.

[0008] As an improvement of the above technical solution, a plurality of groups of mutually offset arc straightening plates are arranged on the upper side of the conveying roller, so that the arc straightening plates at different positions can straighten and reposition the bullfrog after it has been flipped over.

[0009] As an improvement of the above technical solution, a plurality of groups of mutually offset arc push blocks are arranged on the upper side of the power-assisted moving plate through a plurality of push plates, and bullfrogs at different positions can be pushed upward to make them flip sideways through the mutually offset arc push blocks.

[0010] As an improvement of the above technical solution, the top of the arc pushing block is designed to be arc-shaped to prevent the arc pushing block from causing damage to the bullfrog when pushing it upward.

[0011] The beneficial effects of the utility model are as follows: when the bullfrog is being transported, the arc straightening plate, the pushing plate and other structures cooperate to make the bullfrog constantly straighten and flip again, so that the gas sprayed by the liquid nitrogen quick-freezing machine fully contacts the front and back sides of the bullfrog, thereby helping to reduce the freezing time and improving the freezing and preservation effect and efficiency of the bullfrog freezing and preservation device.

[0019] See also Figure 1-4 The utility model provides a technical solution: a frozen bullfrog preservation device, comprising a freezing device body 1, a rear inner wall of the freezing device body 1 is rotatably connected with a conveying roller 2 for conveying bullfrogs, a top inner wall of the freezing device body 1 is fixedly provided with a liquid nitrogen quick-freezing machine 21 for freezing bullfrogs, and a plurality of straightening mechanisms for changing the posture of bullfrogs are fixedly provided on the rear inner wall of the freezing device body 1 and located above the conveying roller 2;

[0020] A flipping mechanism for ejecting the bullfrog and flipping it sideways is slidably provided on the rear inner wall of the refrigeration device body 1 and located below the conveying roller 2 .

[0021] Specifically, the straightening mechanism includes a horizontal fixing plate 3, which is fixedly installed on the rear inner wall of the refrigeration device body 1 and located on the upper side of the conveying roller 2. An arc straightening plate 31 for changing the bullfrog conveying angle is welded to the bottom of the horizontal fixing plate 3. An anti-stuck block 32 is fixedly installed on the bottom of the refrigeration device body 1 and on the rear side of the arc straightening plate 31.

[0022] In this embodiment, the bullfrog is straightened and positioned separately during the conveying process of the conveying roller 2 through the cooperation between the straightening mechanisms.

[0023] Specifically, the flipping mechanism includes an installation slot 4, and an installation slot 4 is opened on the inner wall of the rear side of the freezing device body 1 and located on the lower side of the conveying roller 2. The installation slot 4 is movably connected with a moving block, and a power-assisted moving plate 41 is fixedly installed at the front end of the moving block. A plurality of pushing plates 42 are welded on the top of the power-assisted moving plate 41, and a plurality of arc pushing blocks 43 for ejecting the side-flipping bullfrog are fixedly installed on the top of the pushing plate 42. A power motor 44 is detachably installed on the rear side surface of the freezing device body 1, and the front end of the power motor 44 passes through the inner wall of the rear side of the freezing device body 1 and extends into the inner side of the freezing device body 1. An elliptical power block 45 for pushing the arc pushing block 43 to move upward is fixedly installed on the output end of the power motor 44, and the outer side of the elliptical power block 45 contacts the bottom of the power-assisted moving plate 41.

[0024] In this embodiment, the bullfrog is pushed out during the transportation between the turning mechanisms to cause the bullfrog to turn over.

[0025] Specifically, a plurality of groups of mutually offset circular arc straightening plates 31 are arranged on the upper side of the conveying roller 2 .

[0026] In this embodiment, the arc straightening plates 31 at different positions can straighten and reposition the bullfrog after it has been turned over.

[0027] Specifically, a plurality of groups of mutually staggered arc pushing blocks 43 are arranged on the upper side of the power-assisted moving plate 41 through a plurality of pushing plates 42 .

[0028] In this embodiment, the bullfrogs at different positions can be pushed upwards to turn over by the mutually offset arc pushing blocks 43.

[0029] Specifically, the top of the arc pushing block 43 is designed to be arc-shaped.

[0030] In this embodiment, the arc pushing block 43 is prevented from causing damage to the bullfrog when it is pushed upward.

[0031] When in use, the cleaned bullfrog is placed on the conveying roller 2, and the conveying roller 2 drives the bullfrog to be conveyed from the left side to the right side. When the conveying roller 2 conveys the bullfrog, the liquid nitrogen quick-freezing machine 21 sprays gas to freeze and preserve one side of the bullfrog. When the conveying roller 2 conveys the bullfrog to contact the circular arc straightening plate 31, the circular arc straightening plate 31 straightens the tilted bullfrog and separates and positions the bullfrog. The straightened bullfrog continues to move to the right side, and the power motor 44 is started. The power motor 44 drives the elliptical power block 45 to rotate. In the process of the elliptical power block 45 changing from the horizontal state to the vertical state, it pushes the power-assisted moving plate 41 upward, and the power-assisted moving plate 41 moves upward along the installation card slot 4 through the moving card block. The assisting moving plate 41 drives the pushing plate 42 to move upward, and the pushing plate 42 drives the circular arc pushing block 43 to move upward. When the circular arc pushing block 43 moves upward, it pushes the bullfrog on the upper side of the conveying roller 2 upward, causing the bullfrog to roll over. After the bullfrog rolls over, the liquid nitrogen quick freezing machine 21 freezes and preserves the other side of the bullfrog. Similarly, the working principles of the remaining circular arc straightening plates 31 and the circular arc pushing block 43 are the same as above. When the bullfrog is conveyed, the circular arc straightening plates 31 and the pushing plate 42 and other structures cooperate to make the bullfrog continuously straightened and flipped again, so that the gas ejected by the liquid nitrogen quick freezing machine 21 is in full contact with the front and back sides of the bullfrog. After the bullfrog is frozen, it is conveyed out from the right side of the freezing device body 1.

[0032] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
