Description

Technical Field

[0002] Crayfish is also called Procambarus clarkii, red crayfish and freshwater crayfish. It looks like shrimp but has a hard shell. It is a freshwater economic shrimp. Because of its delicious meat, most factories will prepare crayfish into instant or frozen food in advance to meet people's demand for crayfish.

[0003] At present, on the automatic production line of crayfish, conveyors are usually required to transport crayfish to various processing equipment. Since most of the processing equipment on the production line are at different heights, and the heights of the corresponding conveyors are also different, in order to ensure the processing efficiency of crayfish, a lifting mechanism is usually set between conveyors at different heights to solve the problem of height difference. However, the existing lifting mechanism is usually a climbing belt conveyor. Although it can lift crayfish, due to the inclined state of its belt, the whole machine is not only long and occupies a large space, but also during the lifting process, crayfish are very easy to slide, so it is necessary to lift the crayfish at a slower speed, which leads to a long lifting time and low lifting efficiency.

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment: An automatic lifting machine for crayfish, such as Figure 1-4 As shown, it includes a belt conveyor 1, a lifting conveying mechanism 3, and a belt conveyor 2 which are arranged in sequence. The conveying height of the belt conveyor 1 is lower than that of the belt conveyor 2. The lifting conveying mechanism 3 lifts the lobsters delivered by the belt conveyor 1 and sends them to the belt conveyor 2. The lifting conveying mechanism 3 includes a lifting frame 31, a V-shaped container 1 32 and a V-shaped container 2 33 for holding lobsters, a pair of lifting seats 1 34 which are lifted and arranged on the lifting frame 31 and symmetrically located on both sides of the V-shaped container 1 32, a pair of hinge shafts 1 321 which are fixed at both ends of the V-shaped container 1 32 and rotate through the two lifting seats 1 34 respectively, a pair of lifting seats 2 35 which are lifted and arranged on the lifting frame 31 and symmetrically located on both sides of the V-shaped container 2 33, and a pair of fixed There are hinge shafts 331 fixed at both ends of the V-shaped container and rotating through the two lifting seats 35 respectively, a lifting device 36 driving the two pairs of lifting seats 1 34 and lifting seats 2 35 to vertically and oppositely lift and slide, a rotating device 37 driving the hinge shaft 1 321 to rotate relative to the lifting seat 2 35, and a rotating device 2 38 driving the hinge shaft 2 331 to rotate relative to the lifting seat 2 35. The V-shaped container 1 32 and the V-shaped container 2 33 are respectively close to the output end of the belt conveyor 1 1 and the input end of the belt conveyor 2 2. When the V-shaped container 1 32 is lower than the output end of the belt conveyor 1 1, the lobsters output by the belt conveyor 1 can be received. When the V-shaped container 2 33 is higher than the input end of the belt conveyor 2 2, the lobsters can be flipped and poured into the belt conveyor 2 2.

[0026] Furthermore, a pair of support plates 4 are fixedly provided on the bracket of the belt conveyor 1, and the two support plates 4 are located between the belt conveyor 1 and the lifting frame 31, and a flippable shovel-shaped container 5 is provided between the two support plates 4. Articulated shafts 3 51 that rotate and pass through the two support plates 4 are fixedly provided on both sides of the shovel-shaped container 5, and the articulated shafts 3 51 are located at the upper middle part of the bottom of the shovel-shaped container 5. A rotating device 3 52 for driving the articulated shaft 3 51 to rotate is provided on the support plate 4. The shovel-shaped container 5 is located below one end of the belt of the belt conveyor 1. When the V-shaped container 32 is located above the shovel-shaped container 5, the shovel-shaped container 5 can temporarily receive the lobsters output by the belt conveyor 1. When the V-shaped container 32 is located below the shovel-shaped container 5, the shovel-shaped container 5 can be flipped over to pour the lobsters into the V-shaped container 32.

[0027] Furthermore, the support of the belt conveyor 1 is located above the two support plates 4 and is fixedly provided with a U-shaped guard plate 11. The U-shaped guard plate 11 is located above the shovel-shaped container 5, and the two sides are in an inverted right-angled triangle shape. The bottom of the U-shaped guard plate 11 is horizontal, and when the shovel-shaped container 5 is in a temporary storage state, the top of its side contacts the bottom of the U-shaped guard plate 11. By adopting the above-mentioned U-shaped guard plate 11, not only can the lobsters output by the belt conveyor 1 be ensured to fall safely into the shovel-shaped container 5, but also the bottom plane thereof can limit and position the flipping of the shovel-shaped container 5, so as to ensure that the shovel-shaped container 5 stores the crayfish at a suitable angle.

[0028] Furthermore, a U-shaped guard plate 21 is fixedly provided on the bracket of the belt conveyor 2, and one end of the belt of the belt conveyor 2 is close to the lifting frame 31 and is located in the middle of the U-shaped guard plate 21. By adopting the above-mentioned U-shaped guard plate 21, when the lobsters are poured out of the V-shaped container 23, it is possible to prevent the lobsters from being piled up too high on the belt of the belt conveyor 2, causing the lobsters to slide off the two sides of the belt conveyor 2.

[0029] Furthermore, the lifting device 36 includes a pair of rotating shafts 1 361 rotatably disposed on the lifting frame 31 and close to the upper end of the lifting frame 31, a pair of rotating shafts 2 362 rotatably disposed on the lifting frame 31 and close to the lower end of the lifting frame 31, four sprocket wheels 1 363 respectively fixed on the two rotating shafts 1 361 and the two rotating shafts 2 362, four sprocket wheels 2 364 respectively fixed on the two rotating shafts 1 361 and the two rotating shafts 2 362, a chain 1 365 sleeved on the four sprocket wheels 1 363, a chain 2 366 sleeved on the four sprocket wheels 2 364, and a fixing lifting device 36. A worm gear reduction motor 367 is mounted on a lifting frame 31 and has an output end connected to a rotating shaft 361. Chain 1 365 and chain 2 366 are parallel to each other and are respectively located on both sides of V-shaped container 1 32 or V-shaped container 2 33. Two lifting seats 1 34 are respectively fixed on chain 1 365 and chain 2 366 and are located on the vertical part of chain 1 365 or chain 2 366 close to belt conveyor 1. Two lifting seats 2 35 are respectively fixed on chain 1 365 and chain 2 366 and are located on the vertical part of chain 1 365 or chain 2 366 close to belt conveyor 2 2.

[0030] By adopting the lifting device 36, when the V-shaped container 1 32 and the V-shaped container 2 33 need to be lifted, the worm gear reduction motor 367 first drives the rotating shaft 1 361 to rotate, and then the sprocket 1 363 and the sprocket 2 364 of the rotating shaft 1 361 will respectively drive the two chains to move synchronously. Since the lifting seat 1 34 and the lifting seat 2 35 are fixed on two vertical parts of the chain 1 365 or the chain 2 366 in opposite directions of movement, the chain 1 365 and the chain 2 366 drive the two chains to move synchronously. , the two lifting seats 1 34 and the two lifting seats 2 35 will move up and down in opposite directions respectively. Because the lifting seat 1 34 and the V-shaped container 1 32 are hinged by the hinge shaft 1 321, and the lifting seat 2 35 and the V-shaped container 2 33 are hinged by the hinge shaft 2 331, when the lifting seat 1 34 and the lifting seat 2 35 move up and down, the V-shaped container 1 32 and the V-shaped container 2 33 will move up and down in opposite directions, and cooperate with the flipping device 1 and the flipping device 2 to realize the automatic lifting effect of crayfish.

[0031] Furthermore, the lifting frame 31 includes a pair of vertically parallel plates 311, four connecting rods 312 whose two ends are respectively fixedly connected to the two plates 311 and evenly distributed at the four corners of the plates 311, a rotating shaft 1 361 and a rotating shaft 2 362 are parallelly located in the middle of the four connecting rods, and the two ends are respectively rotatably connected to the two plates 311, a worm gear reduction motor 367 is fixedly installed on the side of one plate 311 facing away from the other plate 311, and one end of a rotating shaft 1 361 rotates through the plate 311 to connect to the output end of the worm gear reduction motor 367. By adopting the above-mentioned lifting frame 31, not only can each component in the lifting device 36 be stably supported, but also its structure is simple, assembly is convenient, and manufacturing cost is low.

[0032] Furthermore, the rotating device 37 includes two pairs of connecting blocks 371 respectively fixed on both sides of the V-shaped container 32, a pair of arc plates 372 fixedly connected to the two pairs of connecting blocks 371 on one side, a pair of sliding posts 373 respectively fixed to the other sides of the two arc plates 372, and a pair of sliding holes 374 respectively opened on the two plates 311 and respectively provided for the two sliding posts 373 to slide. The two pairs of connecting blocks 371 are respectively located on both sides of the vertical parts of the chain 1 365 and the chain 2 366, and are respectively close to the left and right inclined surfaces of the V-shaped container 32. The chain 1 365 and the chain 2 366 are respectively located on the two arc plates 311. In the gap between chain 372 and the two sides of the V-shaped container 32, the sliding hole 374 includes a vertical portion 374a and an arc portion 374b, and the lower end of the arc portion 374b is connected to the upper end of the vertical portion 374a, the trajectory of the vertical portion 374a is tangent to the trajectory of the arc portion 374b, and the axis of the hinge shaft 321 translates along the trajectory of the vertical portion 374a, the arc portion 374b is located in the middle and upper part of the vertical part of the chain 1 365 or the chain 2 366, and the upper end and the axis of the arc portion 374b are both located on the side of the vertical portion 374a close to the V-shaped container 2 33.

[0033] By adopting the above-mentioned rotating device 37, when the V-shaped container 32 just starts to rise from below the shovel-shaped container 5, the sliding column 373 will first slide along the vertical part 374a of the sliding hole 374. Since the axes of the hinge shafts 321 on both sides of the V-shaped container 32 also translate along the track of the vertical part 374a, the hinge shaft 321 and the sliding column 373 will remain aligned up and down during the sliding process of the sliding column 373 in the vertical part 374a. , and the V-shaped container 1 32 will keep the safe angle position of loading lobsters rising continuously during this process; then, when the slide post 1 373 transitions from the upper end of the vertical portion 1 374a to the arc portion 1 374b, the hinge shaft 1 321 still moves horizontally on the track of the vertical portion 1 374a, while the slide post 1 373 will no longer maintain the vertical alignment relationship with the hinge shaft 1 321, and gradually move away from the hinge shaft 1 321 in the horizontal direction. 73 is connected to one side of the V-shaped container through the arc plate 1 and the connecting block 1 371, and the upper end and the axis of the arc portion 1 374b are both located on the side of the vertical portion 1 374a close to the V-shaped container 2 33. Therefore, when the slide column 1 373 slides along the arc portion 1 374b, the V-shaped container 1 32 will tilt toward the V-shaped container 2 33 with the hinge shaft 1 321 as the center; finally, when the slide column 1 373 slides to the upper end of the arc portion 1 374b, the V The V-shaped container 1 32 will reach the best angle position for pouring out the lobsters, and because the arc-shaped portion 1 374b is located in the middle and upper position of the vertical part of the chain 1 365 or the chain 2 366, the V-shaped container 2 33, which moves in the opposite direction to the V-shaped container 1 32, just drops to the bottom of the V-shaped container 1 32 at this time to receive the lobsters poured out by the V-shaped container 1 32, thereby realizing the lobster replacement work between the V-shaped container 1 32 and the V-shaped container 2 33. Among them, the chain 1 365 and the chain 2 366 pass through the gaps on both sides of the two arc plates 1 372 and the V-shaped container 1 32 respectively, which can effectively avoid the problems of interference and collision between the slide column 1 373 and the chain 1 365 or the chain 2 366 when the slide column 1 373 slides along the arc-shaped portion 1 374b, thereby ensuring the flipping safety of the V-shaped container 1 32.

[0034] Furthermore, the rotating device 38 includes a pair of arc plates 382 respectively fixedly connected to the two sides of the V-shaped container 33 on one side, a pair of sliding posts 383 respectively fixed to the other sides of the two arc plates 382, ​​and a pair of sliding holes 384 respectively opened on the two plate bodies 311 and respectively for the two sliding posts 383 to slide. A pair of connecting blocks 381 connected to one side of the arc plates 382 are respectively fixedly arranged on both sides of the V-shaped container 33, and the connecting blocks 381 are respectively close to the left and right inclined surfaces of the V-shaped container 33. The chain 1 365 and the chain 2 366 are respectively located on the two arc plates 311. In the gap between 382 and the two sides of the V-shaped container 33, the sliding hole 384 includes a vertical portion 384a and an arc portion 384b, and the lower end of the arc portion 384b is connected to the upper end of the vertical portion 384a, the trajectory of the vertical portion 384a is tangent to the trajectory of the arc portion 384b, and the axis of the hinge shaft 331 translates along the trajectory of the vertical portion 384a, the arc portion 384b is located at a height position above the belt conveyor 2, and the upper end and the axis of the arc portion 384b are both located on the side of the vertical portion 384a close to the belt conveyor 2.

[0035] When the V-shaped container 33 is loaded with lobsters and just starts to rise, the sliding post 383 will first slide along the vertical part 384a of the sliding hole 384. Since the axes of the hinge shafts 331 on both sides of the V-shaped container 33 also translate along the trajectory of the vertical part 384a, during the sliding process of the sliding post 383 in the vertical part 384a, the hinge shaft 331 and the sliding post 383 will maintain a vertical alignment relationship, and the V-shaped container 33 will maintain a safe angle position for loading lobsters during this process. The sliding column 383 gradually moves away from the hinge shaft 231 in the horizontal direction. Since the sliding column 383 is connected to one side of the V-shaped container through the arc plate 2 and the connecting block 231, and the upper end and the axis of the arc portion 2384b are both located on the side of the vertical portion 2384a close to the belt conveyor 22, during the sliding process of the sliding column 383 along the arc portion 2384b, the V-shaped container 33 will tilt toward the direction of the belt conveyor 22 with the hinge shaft 231 as the center; finally, after the sliding column 383 slides to the upper end of the arc portion 2384b, the V-shaped container 33 will reach the best angle position for pouring out the lobsters, and because the arc portion 2384b is located at a height position above the belt conveyor 22, the V-shaped container 33 will just pour the lobsters onto the upper belt of the belt conveyor 22, thereby realizing the shrimp unloading work of the V-shaped container 233. Among them, chain one 365 and chain two 366 pass through the gaps on both sides of the two arc plates 2 382 and the V-shaped container 2 33 respectively, which can effectively avoid interference and collision between the sliding column 2 383 and chain one 365 or chain two 366 when the sliding column 2 383 slides along the arc portion 2 384b, thereby ensuring the flipping safety of the V-shaped container 2 33.

[0036] Furthermore, the rotating device three 52 includes a sprocket three 521 fixedly connected to one end of the hinge shaft three 51, a rotating shaft three 522 rotating through the plate body 311, a sprocket four 523 fixedly connected to one end of the rotating shaft three 522, a chain three 524 mounted on the sprocket three 521 and the sprocket four 523, a gear 525 fixedly connected to the other end of the rotating shaft three 522, and a rack 526 fixed on the vertical part of the chain one 365 and capable of meshing with the gear 525. The sprocket three 521 and the shovel-shaped container 5 are located on both sides of a support plate 4, the sprocket four 523 and the gear 525 are respectively located on both sides of the plate body 311, the rack 526 is vertically located below a lifting seat one 34, and when the V-shaped container one 32 moves to below the shovel-shaped container 5, the rack 526 and the gear 525 mesh for transmission.

[0037] By adopting the above-mentioned rotating device 352, when the V-shaped container 132 moves to the bottom of the shovel-shaped container 5, the rack 526 will mesh with the gear 525 to rotate, and then the gear 525 drives the rotating shaft and the sprocket 4523 to rotate, and then the sprocket 4523 drives the hinge shaft 351 to rotate through the chain 3524 and the sprocket 3521, and finally the hinge shaft 351 drives the shovel-shaped container 5 to flip, so as to pour the lobsters stored inside into the V-shaped container. Among them, the above-mentioned transmission structure can not only make full use of the movement power of the chain 1365 to realize the flipping of the shovel-shaped container 5, but also the flipping activity of the shovel-shaped container 5 and the lifting activity of the V-shaped container 132 can be performed synchronously at the right time, so the probability of error in flipping the shovel-shaped container 5 is small.

[0038] Furthermore, a pair of cylinders 6 are hingedly connected to the bracket of the belt conveyor 1, and one end of the cylinder 6 hinged to the bracket of the belt conveyor 1 is closed and the other end is open, and a pair of telescopic rods 61 are respectively slid and telescoped inside the cylinder 6, and one end of the two telescopic rods 61 extending out of the cylinder 6 is respectively hingedly connected to the two sides of the shovel-shaped container 5, and a spring 62 is commonly connected between the inner bottom of the cylinder 6 and the end of the telescopic rod 61 located inside the cylinder 6. By using the above-mentioned cylinder 6, telescopic rod 61 and spring 62, not only can resistance to the overturning activity of the shovel-shaped container 5 be given to prevent it from overturning too quickly, but also when the shovel-shaped container 5 is in a state of temporarily collecting lobsters, the U-shaped guard plate 11 can be used to pull and position the shovel-shaped container 5 to maintain this state, so as to prevent the lobster from being affected by the gravity and autonomously overturning.

[0039] The working principle of this embodiment:

[0040] When lifting lobsters, first the low belt conveyor 1 outputs the crayfishes to the shovel-shaped container 5, and then when the crayfishes in the shovel-shaped container 5 are accumulated to a certain amount, the lifting device 36 will drive the V-shaped container 1 32 to descend to the bottom of the shovel-shaped container 5, and then the rotating device 3 52 will drive the shovel-shaped container 5 to flip over, and pour all the crayfishes stored in it into the V-shaped container 1 32, so as to realize the first replacement of crayfishes; then the lifting device 36 will raise the V-shaped container 1 32 filled with crayfishes and lower the empty V-shaped container 2 33, and the rotating device 3 52 will drive the shovel-shaped container 5 to flip back to the initial state to continue to receive crayfishes, and wait until the V-shaped container 1 32 is raised to the highest point of the belt conveyor 1 and the belt conveyor 3 After the V-shaped container 32 reaches the middle height position of the highest point, the V-shaped container 32 just drops to the bottom of the V-shaped container 32. At this time, the rotating device 37 drives the V-shaped container 32 to flip over and pour the crayfish loaded inside into the V-shaped container 33 to achieve the second replacement of the crayfish; finally, the lifting device 36 will raise the V-shaped container 33 loaded with crayfish and lower the empty V-shaped container 32, so that the V-shaped container 32 returns to the bottom of the shovel-shaped container 5 to continue to receive another batch of crayfish, and the V-shaped container 33 is raised to the top of the belt conveyor 2, and under the drive of the rotating device 38, the crayfish are poured onto the belt of the belt conveyor 2, thereby achieving a fast and safe lifting effect of the crayfish.
