Description

Technical Field

[0001] This invention relates to the field of cold storage, specifically a cold storage for preserving frozen meat that facilitates classification. Background Technology

[0002] A cold storage facility is a facility that uses various equipment to refrigerate and maintain a stable low temperature. Cold storage facilities are commonly used for the freezing and refrigeration of food and medicine. In the process of preserving frozen meat, it is necessary to classify and store the frozen meat for easy retrieval later.

[0003] In existing cold storage facilities, the classification of frozen meat is usually done manually. If it is necessary to classify and store two types of frozen meat with significantly different qualities in the cold storage facility, it is currently necessary to classify the two types of meat with different qualities manually.

[0004] In the process of classifying two types of meat with different qualities, current cold storage facilities cannot classify frozen meat of different qualities and can only do so manually; therefore, to address the above problem, a frozen storage facility for preserving and categorizing frozen meat that is easy to classify is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, such as the inability of current cold storage facilities to classify two types of frozen meat of different qualities, this invention proposes a frozen meat preservation cold storage facility that facilitates classification.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: A frozen meat preservation freezer for easy classification, comprising a freezer body, a door hinged to the freezer body, a rectangular opening on the freezer body, a cover plate adapted to the rectangular opening hinged to the freezer body, a fixed platform fixed inside the freezer body, two first vertical plates fixed to the top of the fixed platform, a first rotating shaft rotatably connected between the two first vertical plates via a bearing, two connecting plates fixed to the surface of the first rotating shaft, classification plates fixed to the two connecting plates, two support plates fixed to the top of the fixed platform, a top column slidably inserted into the support plate, the top of the top column contacting the bottom of the classification plate, and the top of the top column being rounded, a circular piece fixed to the bottom of the top column, and a first spring fixed between the circular piece and the fixed platform.

[0007] Preferably, the inner wall of the main body of the freezer is fixed with two inclined plates, and multiple rotating rollers are rotatably connected between the two inclined plates through bearings. The height of the uppermost rotating roller is lower than the rectangular opening, and the height of the lowermost rotating roller is higher than the sorting plate.

[0008] Preferably, three crossbars are fixed between the two inclined plates, and the crossbars are positioned closer to the top of the inclined plates than the rotating roller. A baffle is fixed to the inclined plate, and multiple fixed cones are fixed to the baffle.

[0009] Preferably, two guide rods are fixedly connected to the bottom of the sorting plate, and a movable plate is slidably connected to the surface of the two guide rods. A second spring is fixedly connected between the movable plate and the sorting plate, and the second spring is sleeved on the outside of the guide rods. Four fixed rods are fixedly connected to the top of the movable plate, and two support blocks are fixedly connected to the fixed rods. A blocking rod is fixedly connected to the top of the two support blocks. The cross-section of the blocking rod is a right triangle, and one of the right-angled sides of the triangle is perpendicular to the top of the sorting plate. Four strip openings are opened on the sorting plate, and the blocking rod passes through the strip openings.

[0010] Preferably, the support block includes two fixed blocks, which are respectively fixed to a fixed rod and a barrier rod. A sponge block is fixed between the two fixed blocks. A cylinder is fixed to the lower fixed block. A rod is slidably inserted into the cylinder. The top end of the rod is fixed to the upper fixed block. A lifting plate is fixed to the bottom end of the rod. A third spring is fixed between the lifting plate and the cylinder.

[0011] Preferably, the top of the fixed platform has two second vertical plates fixedly connected to it, and a second rotating shaft is rotatably connected between the two second vertical plates via bearings. One end of the second rotating shaft is fixedly connected to a first circular plate, and a third rotating shaft is rotatably connected to the first circular plate via bearings. One end of the third rotating shaft is fixedly connected to a winding roller, and a torsion spring is fixedly connected between the winding roller and the first circular plate. The torsion spring is sleeved on the outside of the third rotating shaft. A connecting line is wound on the winding roller, and one end of the connecting line is fixedly connected to a moving plate. The other end of the second rotating shaft is fixedly connected to a first sprocket. The top of the fixed platform has a third vertical plate fixedly connected to it, and a fourth rotating shaft is rotatably connected to the third vertical plate via bearings. One end of the fourth rotating shaft is fixedly connected to a second sprocket. A chain is provided above the fixed platform, and the first sprocket and the second sprocket are connected by chain drive. The other end of the fourth rotating shaft is fixedly connected to a gear. A second circular plate is fixedly connected to the surface of the first rotating shaft, and an arc-shaped rack is fixedly connected to the second circular plate. The arc-shaped rack meshes with the gear.

[0012] Preferably, the top of the support plate has a first circular hole, and the top column slides through the first circular hole.

[0013] Preferably, the movable plate has two second circular holes, and the guide rod passes through the second circular holes.

[0014] The advantages of this invention are:

[0015] 1. This invention, through the structural design of a sorting plate, allows for the sorting of frozen meat of different weights. The frozen meat slides onto the sorting plate via rotating rollers. Bars on the sorting plate temporarily prevent the meat from sliding down. After the meat lands on the plate, it rotates around a first axis, pressing the top column downwards. If the frozen meat is of lower weight, the sorting plate remains tilted to the right, allowing the lighter meat to slide down to the right. Conversely, if the frozen meat is of higher weight, the sorting plate tilts to the left, allowing the heavier meat to slide down to the left. This achieves the function of sorting frozen meat of different weights, solving the problem that current cold storage facilities cannot sort two types of frozen meat of different weights.

[0016] 2. This invention utilizes the structural design of the barrier bar. When a small amount of frozen meat falls onto the sorting plate, the rotation of the sorting plate causes the first rotating shaft to rotate. The rotation of the first rotating shaft then causes the second circular plate and the arc-shaped rack to rotate. The arc-shaped rack, through gears, a second sprocket, a chain, and the first sprocket, drives the second rotating shaft to rotate. This causes the winding roller to wind the connecting wire onto the surface. The connecting wire pulls the barrier bar into the slot, and the barrier bar no longer obstructs the frozen meat, allowing it to slide down the sorting plate. When a large amount of frozen meat falls onto the sorting plate, the sorting plate rotates significantly, causing the arc-shaped rack and gears to separate. Since the cross-section of the barrier bar is a right-angled triangle, the barrier bar will not prevent the large amount of meat from sliding down to the left, thus achieving the function of temporarily intercepting the frozen meat.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-9As shown, a frozen meat preservation freezer for easy sorting includes a freezer body 1, a door 2 hinged to the freezer body 1, a rectangular opening 3 on the freezer body 1, a cover plate 4 hinged to the freezer body 1 to fit the rectangular opening 3, a fixed platform 5 fixed inside the freezer body 1, two first vertical plates 6 fixed to the top of the fixed platform 5, a first rotating shaft 7 rotatably connected between the two first vertical plates 6 via a bearing, two connecting plates 8 fixed to the surface of the first rotating shaft 7, sorting plates 9 fixed to the two connecting plates 8, two support plates 10 fixed to the top of the fixed platform 5, a top column 11 slidably inserted into the support plate 10, the top of the top column 11 contacting the bottom of the sorting plate 9, and the top of the top column 11 being rounded, a circular piece 12 fixed to the bottom of the top column 11, and a first spring 13 fixed between the circular piece 12 and the fixed platform 5;

[0030] During operation, when two types of frozen meat with significantly different qualities need to be sorted and placed into the main body 1 of the freezer for preservation and freezing, the door 2 and the cover 4 are opened, and the frozen meat is put in through the rectangular opening 3. The frozen meat falls onto the sorting plate 9, which rotates around the first rotating shaft 7. The top column 11 is pressed downward, and the first spring 13 is compressed. The sorting plate 9 can sort the frozen meat according to its different qualities. Staff need to be stationed on both sides to neatly stack the slid-down frozen meat.

[0031] The inner wall of the main body 1 of the freezer is fixed with two inclined plates 14. Multiple rotating rollers 15 are rotatably connected between the two inclined plates 14 through bearings. The height of the uppermost rotating roller 15 is lower than that of the rectangular opening 3, and the height of the lowermost rotating roller 15 is higher than that of the sorting plate 9.

[0032] Three crossbars 16 are fixed between the two inclined plates 14. The crossbars 16 are positioned closer to the top of the inclined plates 14 than the rotating roller 15. A baffle 17 is fixed to the inclined plate 14, and a plurality of fixed cones 18 are fixed to the baffle 17.

[0033] During operation, frozen meat falls onto the rotating roller 15 and slides down the roller 15. The frozen meat will collide with the baffle 17 and the fixed cone 18. The impact can cause a small amount of ice attached to the surface of the frozen meat to fall off. The ice will fall out from the gap between the rotating rollers 15 to prevent the quality of the ice from affecting the subsequent sorting.

[0034] Two guide rods 19 are fixedly connected to the bottom of the sorting plate 9. A movable plate 20 is slidably connected to the surface of the two guide rods 19. A second spring 21 is fixedly connected between the movable plate 20 and the sorting plate 9. The second spring 21 is sleeved on the outside of the guide rods 19. Four fixed rods 22 are fixedly connected to the top of the movable plate 20. Two support blocks 23 are fixedly connected to the fixed rods 22. A blocking rod 24 is fixedly connected to the top of the two support blocks 23. The cross-section of the blocking rod 24 is a right triangle, and one of the right-angled sides of the triangle is perpendicular to the top of the sorting plate 9. Four slots 25 are opened on the sorting plate 9, and the blocking rod 24 passes through the slots 25.

[0035] During operation, when smaller pieces of frozen meat fall onto the sorting plate 9, the right-angled side of the barrier bar 24 can temporarily stop the frozen meat and prevent it from sliding down.

[0036] The support block 23 includes two fixing blocks 2301, which are respectively fixed to the fixing rod 22 and the blocking rod 24. A sponge block 2302 is fixed between the two fixing blocks 2301. A cylinder 2303 is fixed to the lower fixing block 2301. A rod 2304 is slidably inserted into the cylinder 2303. The top end of the rod 2304 is fixed to the upper fixing block 2301. A lifting plate 2305 is fixed to the bottom end of the rod 2304. A third spring 2306 is fixed between the lifting plate 2305 and the cylinder 2303.

[0037] During operation, when frozen meat falls onto a certain barrier bar 24, the frozen meat will press the barrier bar 24 into the slot 25. The barrier bar 24 will drive the upper fixing block 2301 to move downward. The fixing block 2301 will drive the insertion rod 2304 and the lifting plate 2305 to move downward. The third spring 2306 will be compressed, and the sponge block 2302 will also be compressed, so that a single barrier bar 24 is pressed into the slot 25, preventing all barrier bars 24 from being pressed in.

[0038] Two second vertical plates 26 are fixedly connected to the top of the fixed platform 5. A second rotating shaft 27 is rotatably connected between the two second vertical plates 26 via bearings. A first circular plate 28 is fixedly connected to one end of the second rotating shaft 27. A third rotating shaft 29 is rotatably connected to the first circular plate 28 via bearings. A winding roller 30 is fixedly connected to one end of the third rotating shaft 29. A torsion spring 31 is fixedly connected between the winding roller 30 and the first circular plate 28. The torsion spring 31 is sleeved on the outside of the third rotating shaft 29. A connecting wire 32 is wound on the winding roller 30. One end of the connecting wire 32 is fixedly connected to the moving plate 20. The other end of shaft 27 is fixedly connected to a first sprocket 33. The top of the fixed platform 5 is fixedly connected to a third vertical plate 34. A fourth rotating shaft 35 is rotatably connected to the third vertical plate 34 via a bearing. One end of the fourth rotating shaft 35 is fixedly connected to a second sprocket 36. A chain 37 is provided above the fixed platform 5. The first sprocket 33 and the second sprocket 36 are connected by a drive through the chain 37. The other end of the fourth rotating shaft 35 is fixedly connected to a gear 38. A second circular plate 39 is fixedly connected to the surface of the first rotating shaft 7. An arc-shaped rack 40 is fixedly connected to the second circular plate 39. The arc-shaped rack 40 meshes with the gear 38.

[0039] During operation, when a small piece of frozen meat falls onto the sorting plate 9, the right-angled edge of the blocking bar 24 can temporarily stop the frozen meat, preventing it from slipping down. As the frozen meat falls onto the sorting plate 9, the plate will drive the first rotating shaft 7 to rotate, causing the connecting wire 32 to loosen. Because the torsion spring 31 and the second spring 21 are in balance, the torsion spring 31 is in a torsional state and can wind the loose connecting wire 32 onto the winding roller 30, keeping the connecting wire 32 taut. Due to the small weight of the frozen meat, the sorting plate 9 will rotate a small angle, still tilting to the right. The rotation of the sorting plate 9 and the first rotating shaft 7 will drive the second circular plate 39 to rotate, which in turn drives the arc-shaped rack 40 to rotate. The arc-shaped rack 40 drives the gear 38 to rotate, but the rack 40 will not disengage from the gear 38. The gear 38, through the fourth rotating shaft 35, the second sprocket 36, the chain 37, and the first sprocket 33, drives the second rotating shaft 27 to rotate. The second rotating shaft 27 drives the first circular plate 28 and the torsion spring 31 to rotate. The torsion spring 31 drives the winding roller 30 to rotate, winding the connecting line 32 onto the winding roller 30. As a result, the connecting line 32 pulls the moving plate 20 and the fixed rod 22 to move. The fixed rod 22 drives the support block 23 and the blocking rod 24 to move, pulling the blocking rod 24 back into the strip opening 25, so that the blocking rod 24 will not block the frozen meat. Under the action of gravity, the frozen meat with a smaller mass slides down to the right along the sorting plate 9. When the frozen meat with a larger mass falls on the sorting plate 9, the sorting plate 9 will rotate at a larger angle and tilt to the left. During this process, the blocking rod 24 will block the frozen meat. The arc-shaped rack 40 will pass through the gear 38 and not mesh with it. The blocking rod 24 will first retract downward and then pop out. At the moment of popping out, it will exert a certain pushing force on the frozen meat. The frozen meat with a larger mass will slide down from the right side, realizing the function of sorting two frozen meats with different masses.

[0040] The top of the support plate 10 is provided with a first circular hole 41, and the top column 11 slides through the first circular hole 41;

[0041] During operation, as the disc 12 moves, the top post 11 slides within the first circular hole 41, limiting the disc 12 in the vertical direction.

[0042] The movable plate 20 has two second circular holes 42, and the guide rod 19 passes through the second circular holes 42.

[0043] During operation, as the movable plate 20 moves, the guide rod 19 slides within the second circular hole 42, limiting the movable plate 20 in the direction of the guide rod 19.

[0044] Working principle: When two types of frozen meat with significantly different qualities need to be sorted and placed into the main body 1 of the freezer for preservation and freezing, the door 2 and cover 4 are opened, and the frozen meat is placed in through the rectangular opening 3. The frozen meat falls onto the rotating roller 15 and slides down the rotating roller 15. The frozen meat will collide with the baffle 17 and the fixed cone 18. The impact can cause a small amount of ice attached to the surface of the frozen meat to fall off. The ice will fall out through the gaps between the rotating rollers 15 to prevent the weight of the ice from affecting subsequent sorting. The frozen meat falls onto the sorting plate 9, which will rotate around the first rotating shaft 7. The top column 11 is pressed downward, and the first spring 13 is compressed. When a small piece of frozen meat falls onto the sorting plate 9, the right-angled edge of the barrier bar 24 can temporarily stop it, preventing it from slipping down. As the frozen meat falls onto the sorting plate 9, it causes the first rotating shaft 7 to rotate, loosening the connecting wire 32. Because the torsion spring 31 and the second spring 21 are in balance, the torsion spring 31 is in a torsional state and can wind the loose connecting wire 32 back onto the winding roller 30, keeping the connecting wire 32 taut. Due to the small mass of the frozen meat, the sorting plate 9 will rotate a small angle, still tilting to the right. The rotation of the sorting plate 9 and the first rotating shaft 7 will cause the second circular plate 39 to rotate. The second circular plate 39 drives the arc-shaped rack 40 to rotate, which in turn drives the gear 38 to rotate. The arc-shaped rack 40 will not disengage from the gear 38. The gear 38 drives the second rotating shaft 27 to rotate via the fourth rotating shaft 35, the second sprocket 36, the chain 37, and the first sprocket 33. The second rotating shaft 27 drives the first circular plate 28 and the torsion spring 31 to rotate. The torsion spring 31 drives the winding roller 30 to rotate, winding the connecting wire 32 onto the winding roller 30. As a result, the connecting wire 32 pulls the moving plate 20 and the fixed rod 22 to move. The fixed rod 22 drives the support block 23 and the blocking rod 24 to move, pulling the blocking rod 24 back into the strip opening 25, so that the blocking rod... 24 will not obstruct the frozen meat. Under the action of gravity, the frozen meat with a smaller mass slides down to the right along the sorting plate 9. When the frozen meat with a larger mass lands on the sorting plate 9, the sorting plate 9 will rotate at a large angle and tilt to the left. During this process, the blocking bar 24 will obstruct the frozen meat. The arc-shaped rack 40 will pass through the gear 38 and not mesh with it. The blocking bar 24 will first retract downward and then pop out. At the moment of popping out, it will exert a certain pushing force on the frozen meat. The frozen meat with a larger mass will slide down from the right side, realizing the function of sorting two frozen meats with different masses. Staff need to be set up on both sides to neatly stack the slid-down frozen meat.
