Description

Technical Field

[0001] This invention relates to the field of turtle cutting and processing technology, and in particular to a device for removing the bottom plate of a turtle. Background Technology

[0002] Soft-shelled turtles are a nutritious aquatic product with a large market demand. Currently, soft-shelled turtles are generally slaughtered manually. Because the shell has medicinal value, it's best to keep it intact during slaughter, usually by dissecting the turtle's abdomen (base) to remove the internal organs. However, soft-shelled turtles are resilient, strong, and aggressive, making live dissection far more difficult than with other aquatic products. Processing workers can easily be bitten if not handled carefully. For large-scale processing, the base of each live turtle must be manually removed, which is not only time-consuming and physically demanding but also inefficient and labor-intensive, consequently increasing processing costs. Summary of the Invention

[0003] The purpose of this invention is to provide a device for removing the bottom plate of a turtle, which helps to quickly and manually remove the bottom plate of a live turtle, thereby improving the efficiency and safety of turtle slaughtering.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a turtle bottom plate removal device, comprising a bone sawing machine, the bone sawing machine comprising an upper box and a lower box, a bone sawing processing table fixed on the lower box, and a band saw cutting device installed inside the upper and lower boxes with a saw blade penetrating through the bone sawing processing table, characterized in that a turtle positioning and conveying mechanism is installed on the surface of the bone sawing processing table, the turtle positioning and conveying mechanism comprising a sliding bracket sliding on the bone sawing processing table, an adjusting component for adjusting and locking the relative position of the sliding bracket with respect to the bone sawing processing table, and a turtle positioning plate fixedly installed on the sliding bracket and perpendicular to the bone sawing processing table. The band saw consists of a rotating shaft that rotates vertically on the saw blade processing table, a servo motor fixedly mounted on the head of the upper housing and located at the top of the rotating shaft, a worm gear reducer connecting the output end of the servo motor to the rotating shaft, a flipping bracket fixedly connected to the rotating shaft at one end, and a belt clamping and conveying assembly mounted on the flipping bracket and parallel to the turtle positioning plate. The sliding bracket and the flipping bracket are located on both sides of the saw blade of the band saw cutting equipment, and the sliding bracket and the turtle positioning plate are parallel to each other between the upper housing and the saw blade. The rotating shaft is located behind the saw blade and can drive the belt clamping and conveying assembly to press down the turtle on the turtle positioning plate and convey it through the saw blade.

[0005] By adopting the above technical solution, when it is necessary to process and remove the turtle's bottom plate, the band saw cutting device in the bone saw is started, preparing the saw blade for cutting. Then, the servo motor drives the rotating shaft to rotate, causing the flipping bracket to flip away from the turtle positioning clamp, so that the operator can place the live turtle sideways between the belt clamping conveyor assembly and the turtle positioning plate. After the turtle is placed, the servo motor is started again to drive the rotating shaft to rotate in the opposite direction, reducing the gap between the belt clamping conveyor assembly and the turtle positioning plate, thereby clamping and positioning the turtle between them. At the same time, the belt... The clamping and conveying assembly then begins its transport operation, gradually pushing the turtle closer to the working saw blade. Since the turtle positioning plate and the belt-driven clamping and conveying assembly are located on opposite sides of the saw blade, and the sliding bracket has been pre-adjusted via an adjusting component to maintain a suitable distance between the turtle positioning plate and the saw blade for the turtle's base plate thickness, the turtle's base plate is gradually cut open as it approaches and passes through the saw blade. Finally, after the turtle has completely passed through the saw blade, it and its base plate are completely separated, and the belt-driven clamping and conveying assembly transports it out of the gap between it and the turtle positioning plate. The worm gear reducer installed between the servo motor and the rotating shaft can self-lock the rotating shaft before and after the servo motor starts and stops, ensuring that the belt-driven clamping assembly on the tilting bracket, in conjunction with the turtle positioning plate, stably presses down on and transports the turtle through the saw blade.

[0006] A further configuration of the present invention is as follows: the adjustment assembly includes a guide rod horizontally fixed to the saw bone processing table, a sliding sleeve fixedly installed at one end of the sliding bracket and slidably connected to the guide rod, an L-shaped support plate fixed to the saw bone processing table, a long slot in the L-shaped support plate parallel to the saw bone processing table, a locking screw slidably disposed on the long slot and perpendicularly passing through the other end of the sliding bracket, a nut threadedly connected to the locking screw and clamping the L-shaped support plate and the sliding bracket, and a locking screw threadedly connected to the top of the sliding sleeve and perpendicularly pressing one end against the side wall of the guide rod. The guide rod and the L-shaped support plate are respectively located on the front and rear sides of the saw blade. The saw bone processing table has a scale line printed on one side of the guide rod to indicate the distance between the turtle positioning plate and the saw blade.

[0007] By adopting the above technical solution, when it is necessary to adjust the distance between the turtle positioning plate and the saw blade, first loosen the second locking screw on the top of the sliding sleeve, and unscrew the first locking screw and nut that clamp the L-shaped support plate and the sliding frame. This releases the sliding lock at both ends of the sliding bracket. Then, according to the thickness of the turtle base plate, the operator manually adjusts the movement of the sliding bracket and at the same time checks the scale line on the saw bone processing table. Finally, when the scale line shows that the distance between the turtle positioning plate and the saw blade is appropriate, the operator manually retightens the second locking screw, the second locking screw and the nut to lock both ends of the sliding bracket and fix the position of the turtle positioning plate at this time.

[0008] A further configuration of the present invention is as follows: the belt clamping and conveying assembly includes a pair of belt rollers 1 and 2 respectively vertically rotatably mounted at both ends of the flipping bracket, a single belt roller 3 vertically rotatably mounted on one side of the flipping bracket, a belt sleeved on belt rollers 1, 2 and 3, a servo motor 2 fixedly mounted at one end of the flipping bracket and close to belt roller 1, and a gear reducer connecting the output end of the servo motor 2 and the lower end of the belt roller. Belt roller 1, servo motor 2 and gear reducer are located at the end of the flipping bracket away from the rotation axis, and belt roller 2 is located at the end of the flipping bracket close to the rotation axis. Belt roller 2 is located on the side of the flipping bracket facing the turtle positioning and is located in front of the saw blade.

[0009] By adopting the above technical solution, when a turtle needs to be pressed and conveyed to one side of the turtle positioning plate, the servo motor 2 first drives the belt roller 1 to rotate, causing the belt rollers 1, 2, and 3 to move together. Then, during the belt movement, the belt rollers 2 and 3 press the elastic belt against the turtle's back, allowing the turtle to move along with the belt due to friction between its back and the belt, thus achieving the effect of pressing and conveying the turtle through the saw blade. The relative positions of the belt rollers 1, 2, and 3 on the flipping bracket can increase the inlet width of the gap between the belt and the turtle positioning plate, making it easier for the operator to safely and quickly place the turtle side into the gap for clamping and conveying.

[0010] A further feature of the present invention is that: a pressure plate parallel to the saw blade processing table is slidably disposed on the side of the turtle positioning plate facing the saw blade; the pressure plate is located in front of the saw blade, and an adjustment plate parallel to its side wall is fixedly connected to the side of the turtle positioning plate; a pair of vertical elongated holes are provided above the turtle positioning plate; locking screws passing through the adjustment plate are slidably disposed on the two elongated holes; nuts for clamping the adjustment plate and the turtle positioning plate are threaded onto the locking screws; a turtle guide plate is obliquely fixed to the end of the pressure plate away from the saw blade, and the end of the turtle guide plate away from the pressure plate is higher than the pressure plate.

[0011] By adopting the above technical solution, when the turtle passes through the saw blade, the pressure plate can press down on the top of the turtle. This not only works in conjunction with the belt clamping and conveying assembly and the turtle positioning plate to further improve the stability of the turtle's feeding, but also prevents the turtle from being rotated by the saw blade teeth, thus ensuring the efficiency and quality of the turtle's bottom plate removal. When the turtle's top is too high or too low, first loosen the locking screw three and nut two that clamp the turtle positioning plate and adjusting plate to release the sliding lock of the pressure plate. Then, manually adjust the height of the pressure plate according to the height of the turtle when placed on its side. Finally, after the pressure plate is adjusted to the appropriate height, retighten the locking screw three and nut two to lock the pressure plate in its current position, ensuring that the pressure plate can effectively and stably press down on the top of the turtle. The turtle guide plate facilitates the operator in placing the turtle sideways between the pressure plate, belt, and turtle positioning plate.

[0012] A further feature of the present invention is that a plurality of parallel-spaced rollers are vertically and rotatably mounted on the sliding bracket. The rollers are located between the turtle positioning plate and the upper housing, and the turtle positioning plate has a square hole for the side portion of the rollers to extend out. The elongated hole and the pressure plate are both located above the square hole.

[0013] By adopting the above technical solution, the friction between the turtle's base plate and the turtle's positioning plate can be reduced, thereby ensuring that the belt clamping and conveying assembly can safely and quickly press the turtle through the saw blade.

[0014] A further configuration of the present invention is as follows: the bone sawing processing table includes a base plate fixedly installed on the lower housing and a heightening plate fixedly installed on the base plate. There is a gap between the base plate and the heightening plate, and they are both provided with a saw groove for the saw blade of the band saw cutting equipment to pass through. The turtle positioning and conveying mechanism is installed on the heightening plate. A support frame for installing a servo motor is fixedly provided at the head of the upper housing. The upper and lower ends of the rotating shaft are respectively rotatably connected to the support frame and the heightening plate.

[0015] By adopting the above technical solution, not only can the turtle positioning and conveying mechanism be raised to facilitate the placement or removal of turtles by workers, but also the turtle positioning and conveying mechanism on the bone sawing machine can be quickly assembled or disassembled through the connection structure of the raising plate and the base plate, so that the operator can perform maintenance on the bone sawing machine or the turtle positioning and conveying mechanism in the future.

[0016] A further feature of the present invention is that the bone sawing table is provided with a turtle unloading mechanism at the output end of the belt clamping and conveying assembly and the turtle positioning plate. The turtle unloading mechanism includes an unloading disc that is inclinedly fixed to the extension plate, a single guide roller 1 that is rotatably mounted on the base plate and located between the extension plate and the base plate, multiple guide rollers 2 that are rotatably mounted on the base plate and spaced in parallel, a rotating assembly that drives the guide roller 1 to rotate, and a turtle tray that slides on the base plate and is located below the unloading disc. The guide roller 1 and the guide roller 2 respectively contact the two sides of the turtle tray, and the guide roller 1 can rub against and push the turtle tray to move horizontally along the lower end of the unloading disc. The unloading disc is located at one end of the turtle positioning plate near the rotating shaft and the side of the flipping bracket near the turtle positioning plate.

[0017] By adopting the above technical solution, when the turtle's bottom plate is cut open and leaves the gap between the turtle positioning plate and the belt, it will naturally slide from the unloading tray into the turtle tray. At the same time, the rotating component will drive the guide roller one to rotate after the turtle slides into the turtle tray and before the next turtle slides into the turtle tray. Since the guide roller one and the guide roller two are in parallel contact with the two sides of the turtle tray, when the guide roller one rotates, it will push the turtle tray forward a certain distance, so that each turtle can be placed in the turtle tray in sequence. This not only helps the operator to retrieve the turtles and improves the efficiency of turtle bottom plate cutting, but also helps the operator to carry out subsequent slaughtering processes such as cleaning the turtle's internal organs when the turtles are arranged in the turtle tray.

[0018] A further configuration of the present invention is as follows: the rotating assembly includes a driving large gear, a driven small gear, and a one-way bearing; the lower end of the rotating shaft rotates through the heightening plate and is fixedly inserted into the inner ring of the one-way bearing; the driving large gear is fixedly sleeved on the outer ring of the one-way bearing; the driven small gear is fixedly installed on the bottom of the first guide roller and meshes with the driving large gear; the tooth tip circle diameter of the driven small gear is smaller than the outer ring diameter of the first guide roller.

[0019] By adopting the above technical solution, when the rotating shaft rotates and drives the flipping bracket to approach the turtle positioning plate, the one-way bearing connected to the lower end of the rotating shaft will transmit its rotation to the driving gear. Then, the driving gear will mesh with the driven pinion, causing the driven pinion to drive the guide roller one to rotate. This, in turn, works with the guide roller two to automatically push the turtle tray forward a certain distance during the interval between the turtles sliding into the turtle tray. When the rotating shaft rotates and drives the flipping bracket away from the turtle positioning plate, the one-way bearing connected to the lower end of the rotating shaft will slip, preventing the rotation of the rotating shaft from being transmitted to the driving gear. This avoids the guide roller two from rotating in the opposite direction again after pushing the turtle tray forward, pulling the turtle tray back.

[0020] A further feature of the present invention is that a plurality of vertically spaced guide rollers are rotatably mounted on both sides of the base plate located on the guide roller one. The guide rollers three and guide roller one have the same diameter and are flush with one side of the turtle tray.

[0021] By adopting the above technical solution, the stability of the turtle tray sliding can be further guaranteed.

[0022] A further feature of the present invention is that a plurality of parallel and spaced rollers are rotatably mounted on the unloading disc, and the rollers are located parallel to each other on the inclined surface of the unloading disc.

[0023] By adopting the above technical solution, it is possible to further ensure that the turtle with its bottom plate cut open can slide safely and quickly into the turtle tray.

[0024] The beneficial effects of this invention are:

[0025] 1. Through the turtle positioning plate on the sliding bracket and the belt clamping conveyor on the flipping bracket in the turtle positioning and conveying mechanism, the turtle can not only be clamped and conveyed through the saw blade on the bone sawing machine to help the operator cut the bottom plate of the turtle safely and quickly, but also, in conjunction with the adjustment component, pressure plate and turtle positioning plate connection structure, the turtle positioning and conveying mechanism can adapt to turtles of various thicknesses and heights. Thus, while improving the efficiency and safety of turtle slaughtering, it can also ensure that the device has a sufficient range of applications.

[0026] 2. The unloading disc, guide roller one, guide roller two, and turtle tray in the turtle unloading mechanism not only work in conjunction with the turtle positioning and conveying mechanism to help operators automatically retrieve turtles with their bottom plates cut off, thus improving the efficiency of turtle bottom plate removal, but also, through the transmission structure of the driving large gear, driven small gear, and one-way bearing in the rotating assembly, the rotational power of the rotating shaft in the turtle positioning and conveying mechanism can be converted into the power required to move the turtle tray by friction of the guide roller one. Thus, while achieving the effect of automatic turtle unloading, the energy used to drive the turtle positioning and conveying mechanism can be fully utilized, improving the overall energy utilization rate of the device.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Example: A device for removing the bottom plate of a turtle, such as... Figure 1 , Figure 2As shown, the device includes a bone sawing machine 1, which comprises an upper housing 11 and a lower housing 12, a bone sawing processing table 13 fixed on the lower housing 12, and a band saw cutting device 14 installed inside the upper housing 11 and the lower housing 12 with a saw blade 141 passing through the bone sawing processing table 13. A turtle positioning and conveying mechanism 2 is installed on the surface of the bone sawing processing table 13. The turtle positioning and conveying mechanism 2 includes a sliding bracket 21 that slides on the bone sawing processing table 13, an adjusting component 22 that adjusts and locks the relative position of the sliding bracket 21 with respect to the bone sawing processing table 13, a turtle positioning plate 23 fixedly installed on the sliding bracket 21 and perpendicular to the bone sawing processing table 13, a rotating shaft 24 that rotates perpendicularly on the bone sawing processing table 13, and a fixed mounting... The servo motor 25 is located at the top of the upper housing and on the top of the rotating shaft 24. A worm gear reducer 26 connects the output end of the servo motor 25 and the rotating shaft 24. A flip bracket 27 is fixedly connected to the rotating shaft 24 at one end. A belt clamping and conveying assembly 28 is installed on the flip bracket 27 and parallel to the turtle positioning plate 23. The sliding bracket 21 and the flip bracket 27 are located on both sides of the saw blade 141 of the band saw cutting equipment 14. The sliding bracket 21 and the turtle positioning clamp are parallel between the upper housing and the saw blade 141. The rotating shaft 24 is located behind the saw blade 141 and can drive the belt clamping and conveying assembly 28 to press the turtle on the turtle positioning plate 23 and convey it through the saw blade 141.

[0037] By employing the aforementioned turtle bottom plate removal device, when the turtle's bottom plate needs to be removed, the band saw cutting device 14 in the bone saw 1 is activated, preparing the saw blade 141 for cutting. Then, the servo motor 25 drives the rotating shaft 24 to rotate, causing the flipping bracket 27 to flip away from the turtle positioning clamp, allowing the operator to place the live turtle sideways between the belt clamping conveyor assembly 28 and the turtle positioning plate 23. After the turtle is placed, the servo motor is activated again to drive the rotating shaft 24 to rotate in the opposite direction, reducing the gap between the belt clamping conveyor assembly 28 and the turtle positioning plate 23, thereby clamping and positioning the turtle between them. Simultaneously, the belt clamping conveyor assembly 28... The conveying process begins at step 8, gradually pushing the turtle closer to the working saw blade 141. Since the turtle positioning plate 23 and the belt-clamping conveyor assembly 28 are located on either side of the saw blade 141, and the sliding bracket 21 has previously been adjusted via the adjusting assembly 22 to maintain a suitable distance between the turtle positioning plate 23 and the saw blade 141 for the turtle's base plate thickness, the turtle's base plate 131 is gradually cut by the saw blade 141 as it approaches and passes through. Finally, after the turtle has completely passed through the saw blade 141, the turtle and its base plate 131 are completely separated, and the turtle is simultaneously conveyed out of the gap between itself and the turtle positioning plate by the belt-clamping conveyor assembly 28. The worm gear reducer 26 installed between the servo motor 25 and the rotating shaft 24 can self-lock the rotating shaft 24 before and after the servo motor starts and stops, ensuring that the belt 284 clamping assembly on the flipping bracket 27, in conjunction with the turtle positioning plate 23, stably presses down on and conveys the turtle through the saw blade 141.

[0038] like Figure 2 , Figure 3 As shown, the adjustment assembly 22 includes a guide rod 221 horizontally fixed on the saw processing table 13, a sliding sleeve 222 fixedly installed on one end of the sliding bracket 21 and slidably connected to the guide rod 221, an L-shaped support plate 223 fixed on the saw processing table 13, an elongated hole 224 opened on the L-shaped support plate 223 and parallel to the saw processing table 13, a locking screw 225 slidably set on the elongated hole 224 and vertically passing through the other end of the sliding bracket 21, a nut 226 threadedly connected to the locking screw 225 and clamping the L-shaped support plate 223 and the sliding bracket 21, and a locking screw 227 threadedly connected to the top of the sliding sleeve 222 and vertically pressing against the side wall of the guide rod 221. The guide rod 221 and the L-shaped support plate 223 are located on the front and rear sides of the saw blade 141, respectively. The saw processing table 13 has a scale line 228 printed on one side of the guide rod 221 to show the distance between the turtle positioning plate 23 and the saw blade 141. By using the aforementioned adjustment component 22, when it is necessary to adjust the distance between the turtle positioning plate 23 and the saw blade 141, first loosen the second locking screw 227 on the top of the sliding sleeve 222, and loosen the first locking screw 225 and nut 226 that clamp the L-shaped support plate 223 and the sliding frame, thereby releasing the sliding lock at both ends of the sliding bracket 21. Then, according to the thickness of the turtle base plate, the operator manually adjusts the movement of the sliding bracket 21 and at the same time checks the scale line 228 on the bone saw processing table 13. Finally, when the scale line 228 shows that the distance between the turtle positioning plate 23 and the saw blade 141 is appropriate, the operator manually retightens the second locking screw 227, and tightens the second locking screw and nut 226 to lock both ends of the sliding bracket 21 and fix the position of the turtle positioning plate 23 at this time.

[0039] like Figure 2 , Figure 5As shown, the belt clamping and conveying assembly 28 includes a pair of belt rollers 281 and 282 that are vertically rotatably mounted at both ends of the flipping bracket 27, a single belt roller 283 that is vertically rotatably mounted on one side of the flipping bracket 27, a belt 284 that is sleeved on belt rollers 281, 282 and 383, a servo motor 285 that is fixedly mounted on one end of the flipping bracket 27 and close to belt roller 281, and a gear reducer 286 that connects the output end of the servo motor 285 and the lower end of belt roller 281. Belt roller 281, servo motor 285 and gear reducer 286 are located at the end of the flipping bracket 27 away from the rotating shaft 24, and belt roller 282 is located at the end of the flipping bracket 27 close to the rotating shaft 24. Belt roller 282 is located on the side of the flipping bracket 27 facing the turtle positioning and in front of the saw blade 141. By employing the aforementioned belt clamping and conveying assembly 28, when a turtle placed on one side of the turtle positioning plate 23 needs to be pressed and conveyed, the servo motor 285 first drives the belt roller 281 to rotate, causing the belt 284, which is fitted together by the belt rollers 281, 282, and 283, to move. Then, during the movement of the belt 284, the belt rollers 282 and 283 press and adhere the elastic belt 284 to the turtle's back, causing the turtle to move along with the belt 284 due to friction between its back and the belt 284, thus achieving the effect of pressing and conveying the turtle through the saw blade 141. The relative positions of the belt rollers 281, 282, and 283 on the flipping bracket 27 can, to a certain extent, widen the inlet width of the gap between the belt 284 and the turtle positioning plate 23, thereby facilitating the operator to safely and quickly place the turtle side into the gap for clamping and conveying.

[0040] like Figure 3 , Figure 4As shown, a pressure plate 29 parallel to the saw bone processing table 13 is slidably disposed on the side of the turtle positioning plate 23 facing the saw blade 141. The pressure plate 29 is located in front of the saw blade 141, and an adjustment plate 291 parallel to its side wall is fixedly connected to the side of the turtle positioning plate 23. A pair of vertical elongated holes 231 are opened above the turtle positioning plate 23. Locking screws 293 passing through the adjustment plate 291 are slidably disposed on the two elongated holes 231. Nuts 294 for clamping the adjustment plate 291 and the turtle positioning plate 23 are threadedly connected to the locking screws 293. A turtle guide plate 292 is obliquely fixed to the end of the pressure plate 29 away from the saw blade 141, and the end of the turtle guide plate 292 away from the pressure plate 29 is higher than the pressure plate 29. By using the aforementioned pressure plate 29, when the turtle passes through the saw blade 141, the pressure plate 29 can press down on the top of the turtle. This not only works in conjunction with the belt clamping and conveying assembly 28 and the turtle positioning plate 23 to further improve the stability of the turtle's feeding, but also prevents the turtle from being rotated by the saw teeth of the saw blade 141, thereby ensuring the efficiency and quality of the turtle's bottom plate removal. When the top of the turtle is too high or too low, first loosen the locking screws 293 and nut 294 that clamp the turtle positioning plate 23 and the adjusting plate to release the sliding lock of the pressure plate 29. Then, manually adjust the height of the pressure plate 29 according to the height of the turtle when it is placed on its side. Finally, after the pressure plate 29 is adjusted to a suitable height, tighten the locking screws 293 and nut 294 again to lock the position of the pressure plate 29, ensuring that the pressure plate 29 can effectively and stably press down on the top of the turtle. The turtle guide plate 292 allows the operator to easily place the turtle sideways between the pressure plate 29, the belt 284, and the turtle positioning plate 23.

[0041] like Figure 3 , Figure 4 As shown, multiple parallel rollers 211 are vertically and rotatably mounted on the sliding bracket 21. The rollers 211 are located between the turtle positioning plate 23 and the upper housing. The turtle positioning plate 23 has a square hole 212 for the side of the rollers 211 to extend out. The elongated hole 231 and the pressure plate 29 are both located above the square hole 212. By using the rollers 211, the friction between the turtle bottom plate and the turtle positioning plate 23 can be reduced, so as to ensure that the belt clamping and conveying assembly 28 can safely and quickly press the turtle through the saw blade 141.

[0042] like Figure 1 , Figure 2As shown, the bone sawing table 13 includes a base plate 131 fixedly installed on the lower housing 12 and a riser plate 132 fixedly installed on the base plate 131. There is a gap between the base plate 131 and the riser plate 132, and both have a saw groove for the saw blade 141 of the band saw cutting device 14 to pass through. The turtle positioning and conveying mechanism 2 is installed on the riser plate 132. A support frame 111 for installing a servo motor 25 is fixedly installed at the head of the upper housing. The upper and lower ends of the rotating shaft 24 are rotatably connected to the support frame 111 and the riser plate 132, respectively. By adopting the connection structure of the base plate 131 and the riser plate 132, the turtle positioning and conveying mechanism 2 can be raised to facilitate the placement or removal of turtles by the operator. Moreover, the connection structure between the riser plate 132 and the base plate 131 allows for quick assembly or disassembly of the turtle positioning and conveying mechanism 2 on the bone sawing machine 1, facilitating subsequent maintenance of the bone sawing machine 1 or the turtle positioning and conveying mechanism 2 by the operator.

[0043] like Figure 2 As shown, the bone sawing table 13 is also equipped with a turtle discharge mechanism 3 at the output end of the belt clamping and conveying assembly 28 and the turtle positioning plate 23. The turtle discharge mechanism 3 includes a discharge plate 31 that is tilted and fixed on the raising plate 132, a single guide roller 33 that is rotatably mounted on the base plate 131 and located between the raising plate 132 and the base plate 131, multiple guide rollers 34 that are rotatably mounted on the base plate 131 and spaced in parallel, a rotating assembly 37 that drives the guide roller 33 to rotate, and a turtle tray 36 that slides on the base plate 131 and is located below the discharge plate 31. The guide roller 33 and the guide roller 34 respectively contact the two sides of the turtle tray 36, and the guide roller 33 can rub and push the turtle tray 36 to move along the lower end of the discharge plate 31. The discharge plate 31 is located at one end of the turtle positioning plate 23 near the rotating shaft 24 and the side of the flipping bracket 27 near the turtle positioning plate 23. By employing the aforementioned turtle unloading mechanism 3, when the turtle's bottom plate is cut open and leaves the gap between the turtle positioning plate 23 and the belt 284, it will naturally slide from the unloading tray 31 into the turtle tray 36. Simultaneously, the rotating component 37 will drive the guide roller 33 to rotate after the turtle slides into the turtle tray 36 and before the next turtle slides into the turtle tray 36. Since the guide roller 33 and the guide roller 34 are in parallel contact with both sides of the turtle tray 36, when the guide roller 33 rotates, it will push the turtle tray 36 forward a certain distance, thereby allowing each turtle to be placed in the turtle tray 36 in sequence. This not only helps the operator to retrieve the turtles and improves the efficiency of turtle bottom plate cutting, but also, the arrangement of the turtles in the turtle tray 36 helps the operator to carry out subsequent turtle viscera removal and other slaughtering processes.

[0044] like Figure 2 , Figure 3As shown, the rotating assembly 37 includes a driving large gear 371, a driven small gear 372, and a one-way bearing 373. The lower end of the rotating shaft 24 rotates through the heightening plate 132 and is fixedly inserted into the inner ring of the one-way bearing 373. The driving large gear 371 is fixedly sleeved on the outer ring of the one-way bearing 373. The driven small gear 372 is fixedly installed on the bottom of the guide roller 33 and meshes with the driving large gear 371. The tooth tip circle diameter of the driven small gear 372 is smaller than the outer ring diameter of the guide roller 33. By employing the aforementioned rotating component 37, when the rotating shaft 24 rotates and drives the flipping bracket 27 to approach the turtle positioning plate 23, the one-way bearing 373 connected to the lower end of the rotating shaft 24 will transmit its rotation to the driving gear 371. Then, the driving gear 371 will mesh with the driven gear 372, causing the driven gear 372 to drive the guide roller 33 to rotate. This, in turn, cooperates with the guide roller 34 to automatically push the turtle tray 36 forward a certain distance during the interval between the turtles sliding into the turtle tray 36. When the rotating shaft 24 rotates and drives the flipping bracket 27 away from the turtle positioning plate 23, the one-way bearing 373 connected to the lower end of the rotating shaft 24 will slip, preventing the rotating shaft 24 from transmitting its rotation to the driving gear 371. This avoids the guide roller 34 from rotating in the opposite direction again after pushing the turtle tray 36 forward, pulling the turtle tray 36 back. The base plate 131 is rotatably mounted on both sides of the guide roller 33 with multiple vertically spaced guide rollers 35. The guide rollers 35 and guide roller 33 have the same diameter and are flush with one side of the turtle tray 36, which can further ensure the stability of the turtle tray 36 sliding. The unloading tray 31 is rotatably mounted with multiple parallel and spaced rollers 32, which are parallel to each other on the inclined surface of the unloading tray 31, which can further ensure that the turtle cut open by the base plate 131 can slide safely and quickly into the turtle tray 36.
