[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

Among them, the telescopic rod 4 can be an electric push rod, a hydraulic cylinder or a cylinder. A bone placing groove 33 is provided on the bone placing platform 6, and the length direction of the bone placing groove 33 is perpendicular to the length direction of the cutting groove 7, and the depth of the cutting groove 7 is deeper than that of the bone placing groove 33.

[0018] In the present scheme, when using the livestock bone cutting and bone marrow separation device to cut the livestock bone, the bone is first placed on the bone placing platform 6, and then the bone is fixedly clamped by the clamping mechanism, and then the bone cutting knife 5 and the two bone piercing spurs 8 are driven to descend by the telescopic rod 4, so that the bone cutting knife 5 squeezes and cuts the bone below, and at the same time, the two bone piercing spurs 8 pierce the upper surface of the bone. When the bone cutting knife 5 cuts the bone, the two bone piercing spurs 8 both penetrate the bone. At this time, the bone is squeezed and cut into two sections by the bone cutting knife 5, but due to the fixing effect of the clamping mechanism and the two bone piercing spurs 8, the two sections of the bone are still fixed on the original position of the bone placing platform 6, and the corresponding ends of the two sections of the bone are clamped tightly on the corresponding side walls of the bone cutting knife 5. The gas delivery cavity 9 of the thorn 8 is connected to the bone marrow cavity of the corresponding bone through the gas outlet 10, that is, the gas outlet 10 of each bone piercing thorn 8 is located inside the bone marrow cavity of the corresponding bone, and the two liquid inlets 12 of the guide cavity 11 of the bone cutting knife 5 are both connected to the bone marrow cavity of the corresponding segment of bone. The gas is delivered to the bone marrow cavity of the two segments of bone through the gas delivery component, so that the bone marrow inside the two segments of bone is blown and squeezed into the guide cavity 11 of the bone cutting knife 5, and the bone marrow flows into the lower liquid collecting tank 14 through the liquid outlet 13 of the bone cutting knife 5 for collection and temporary storage; this scheme can not only realize the cutting of the bone, but also separate and collect the bone marrow in the bone, which is convenient for separating and recycling the bone marrow, and then convenient for the subsequent preparation of bone marrow into bone marrow food. By setting the guide cavity 11 inside the bone cutting knife 5, it is convenient to directly introduce the bone marrow inside the bone into the lower liquid collecting tank 14 as much as possible. If there is no guide channel, the bone marrow may be blown to other parts outside the liquid collecting tank 14, thereby causing a waste of bone marrow. The rod bone is fixed by the device of the present invention during the whole process of being cut, which to a certain extent prevents the risk of ejection and injury to people when the rod bone is cut, and improves the safety performance of the device of the present invention in cutting the rod bone.

[0019] Specifically, a mounting plate 15 is provided at the lower end of the telescopic rod 4 , the mounting plate 15 is slidably sleeved on the plurality of guide pillars 2 , the bone cutting knife 5 is provided on the mounting plate 15 , and two bone piercing spurs 8 are provided on the mounting plate 15 .

[0020] The clamping mechanism includes a first bone clamping plate 17, a second bone clamping plate 18 and two horizontal electric push rods 19 located on the frame 1; the first bone clamping plate 17 and the second bone clamping plate 18 are arranged opposite to each other and are both higher than the bone placing platform 6, and the bone placing platform 6 is located between the plate surfaces of the first bone clamping plate 17 and the second bone clamping plate 18, and the first bone clamping plate 17 and the second bone clamping plate 18 are both slidably arranged on the frame 1 along the direction approaching and away from the bone placing platform 6, and the sliding directions of the first bone clamping plate 17 and the second bone clamping plate 18 are consistent, and two slide grooves 20 are opened along a straight line on the frame 1, and the two slide grooves 20 are respectively located on both sides of the bone placing platform 6, and the first bone clamping plate 17 and the second bone clamping plate 18 are respectively arranged on both sides of the bone placing platform 6. Slide blocks are provided on the plates 18, and the two slide blocks are both located in the corresponding slide grooves 20 and slideably cooperate with the corresponding slide grooves 20. The cross-sectional shapes of the slide grooves 20 and the slide blocks are both inverted T-shaped or trapezoidal, which is convenient for limiting the sliding direction of the first clamping plate 17; the fixed ends of the two horizontal push rods are respectively connected to the frame 1, the extended end of one of the horizontal electric push rods 19 is connected to the first clamping plate 17, and the extended end of the other horizontal electric push rod 19 is connected to the second clamping plate 18, and the length directions of the two horizontal electric push rods 19 are consistent with the sliding direction of the first clamping plate 17, and the length direction of the mounting seam 16 is consistent with the length direction of the horizontal electric push rods 19.

[0021] The bone is placed on the bone placing platform 6, and the bone placing platform 6 supports the middle part of the bone, so that one end of the bone is toward the first bone clamping plate 17 and the other end is toward the second bone clamping plate 18, and then the horizontal electric push rod 19 is controlled to extend, so that the horizontal electric push rod 19 drives the first bone clamping plate 17 to move toward the second bone clamping plate 18, so that the first bone clamping plate 17 and the second bone clamping plate 18 clamp and fix the bone on the bone placing platform 6, and then the bone cutting knife 5 can be driven by the telescopic rod 4 to press down and cut the bone, and at the same time, the mounting plate 15 is used to press down the two bone piercing spurs 8 below. The limiting nut 23 then drives the two bone piercing spurs 8 to puncture the two ends of the rod bone. In addition, when the bone cutting knife 5 is squeezing and cutting the rod bone, the bone cutting knife 5 can also squeeze and fix the rod bone below, which can prevent the rod bone from shifting when the bone piercing spur 8 punctures the rod bone to a certain extent; similarly, the two bone piercing spurs 8 can fix the rod bone while puncturing the corresponding section of the rod bone, which can prevent the rod bone from shifting when being cut by the bone cutting knife 5 to a certain extent, that is, the bone cutting knife 5 and the two bone piercing spurs 8 can achieve a mutually synergistic and promoting effect.

[0022] More specifically, the gas delivery component includes an air delivery pump 21 and an air delivery pipe 22. The air delivery pump 21 is located on the frame 1. One end of the air delivery pipe 22 is connected to the air outlet end of the air delivery pump 21, and the other end is respectively connected to the air delivery cavities 9 of the two bone spurs 8.

[0023] Start the air pump 21, and the air pump 21 delivers gas to the air delivery cavity 9 of the bone spur 8 through the air delivery pipe 22. The gas is delivered to the bone marrow cavity of the spur through the air delivery cavity 9. After the gas enters the bone marrow cavity, the bone marrow inside the bone marrow cavity can be purged, and the bone marrow can be purged into the guide cavity 11 of the bone cutting knife 5 through the liquid inlet 12 of the bone cutting knife 5. The bone marrow is discharged through the liquid outlet 13 below the guide cavity 11, and the bone marrow finally flows into the liquid collecting tank 14 below for temporary storage.

[0024] Based on Example 1, in this example, reference Figure 1 , Figure 3 The first splint plate 17 and the second splint plate 18 are provided with a plurality of anti-skid protrusions on the opposite plate surfaces, and the anti-skid protrusions are conical protrusions 24, and the tip of the conical protrusions 24 faces the direction of the bone placing platform 6. The conical protrusions 24 can be conical or pyramidal.

[0025] On the one hand, the multiple conical protrusions 24 are used to increase the friction coefficient on the surface of the first splint 17 and the second splint 18, so as to increase the friction force between the two splints and the corresponding ends of the bone. On the other hand, the conical protrusions 24 can squeeze out multiple grooves on the end surfaces of the two ends of the bone, so as to increase the stability of the first splint 17 and the second splint 18 in clamping the bone, and prevent the bone from shifting during the puncture of the bone piercing spur 8.

[0026] Based on Example 1, in this example, reference Figure 1 , Figure 2 , Figure 3 The frame 1 is provided with a bone removal plate 25, which is located above the bone placing table 6. The bone removal plate 25 is provided with a puncture slit 26 for two bone piercing spurs 8 to pass through and a knife slit 27 for the bone cutting knife 5 to pass through; the mounting plate 15 is provided with two through mounting slits 16 along a straight line, and the two mounting slits 16 are respectively located on both sides of the telescopic rod 4, and the length directions of the two puncture slits 26 and the two mounting slits 16 are consistent with the length direction of the horizontal electric push rod 19, and each mounting slit 16 is provided with a bone piercing spur 8 , two limiting nuts 23 are provided on each bone piercing spur 8 through a threaded sleeve, one limiting nut 23 is located above the mounting plate 15, and the other is located below the mounting plate 15, the outer diameters of the two limiting nuts 23 are larger than the size of the corresponding mounting seam 16, the outer diameter of each bone piercing spur 8 is adapted to the width of the corresponding mounting seam 16, the two limiting nuts 23 limit the corresponding bone piercing spur 8 at the corresponding mounting seam 16, and each bone piercing spur 8 can slide at the corresponding mounting seam 16 along the length direction of the corresponding mounting seam 16. It should be noted that the two limiting nuts 23 do not fix the corresponding bone piercing spur 8, that is, the bone piercing spur 8 is not clamped by the two limiting nuts 23.

[0027] When the telescopic rod 4 drives the bone piercing spur 8 and the bone cutting knife 5 to descend, the two bone piercing spurs 8 move downward through the corresponding puncture slits 26 to puncture the lower bone, and the bone cutting knife 5 moves downward through the knife slits 27 to cut the lower bone. After the bone marrow is blown out, the horizontal electric push rod 19 is shortened first to release the squeezing effect of the first bone clamping plate 17 on the bone, and then the bone cutting knife 5 and the two bone piercing spurs 8 are driven to rise through the telescopic rod 4. When the two sections of the bone rise to the lower surface of the bone removal plate 25, the bone removal plate 25 is used to prevent the two sections of the bone from continuing to move upward, the bone cutting knife 5 continues to move upward through the knife slits 27, and the two bone piercing spurs 8 continue to move upward through the corresponding puncture slits 26, thereby achieving the effect of separating the two sections of the bone from the bone piercing spurs 8, which is convenient for recovering the bone. The bone marrow inside the bone is not easy to be completely blown out, and the remaining bone marrow in the bone and the meat outside the bone can be used for making soup.

[0028] In addition, the provision of the guide cavity 11 inside the bone cutting knife 5 is not a conventional setting method, which is likely to reduce the mechanical properties of the bone cutting knife 5. Therefore, the thickness of the bone cutting knife 5 can be set thicker than that of a conventional cutter. However, when such a thicker bone cutting knife 5 is used to cut the bar bone, the bone cutting knife 5 will exert an extrusion force on both ends of the middle part of the bar bone, which is likely to damage the shape structure of the middle section of the bar bone, which is not conducive to the connection between the bone marrow cavity of the bar bone and the liquid inlet 12 of the bone cutting knife 5. In the present scheme, when the bone cutting knife 5 cuts the bar bone, the two horizontal electric push rods 19 can be controlled to contract to facilitate the translation of the two sections of the bar bone to both sides. While the two sections of the bar bone are translated, the corresponding bone piercing spurs 8 are driven to translate, so that the two sections of the bar bone are not easily damaged or excessively deformed due to the downward movement of the bone cutting knife 5. The two horizontal electric push rods 19 can be manually controlled to retract a certain distance to facilitate the movement of the two sections of the bone and the two bone spurs 8. The two bone spurs 8 move along the corresponding installation seams 16 and the corresponding puncture seams 26. A pressure sensor can also be set between the two horizontal electric push rods 19 and the corresponding bone clamping plates. The pressure sensor is used to monitor the squeezing force of the first bone clamping plate 17 and the second bone clamping plate 18 on the bone. When the bone cutting knife 5 cuts the bone downward, the two ends of the bone will slightly shift toward the bone clamping plates at the corresponding ends, which will cause the pressure data monitored by the pressure sensor to increase. When the pressure data of the pressure sensor increases, the horizontal electric push rod 19 at the corresponding end can be controlled to retract by the PLC controller or the single-chip microcomputer until the pressure data drops below the preset value.

[0029] Based on Example 1, in this example, reference Figure 1 , Figure 2, telescopic holes 28 are provided on both inner side walls of the cutting groove 7, and the telescopic holes 28 are inclined. The end of the telescopic hole 28 close to the cutting groove 7 is the highest inclined end, and a telescopic column 29 is slidably arranged in each telescopic hole 28, one end of the telescopic column 29 is located inside the corresponding telescopic hole 28, and the other end extends into the cutting groove 7 and is provided with an abutment plate 30, and a silicone pad 31 is provided on the abutment plate 30, and each abutment plate 30 is provided with a spring 32 at one end close to the corresponding telescopic column 29, and each spring 32 is connected to the inner side wall of the cutting groove 7 on the corresponding side at one end away from the corresponding abutment plate 30, and the two silicone pads 31 are tightly pressed against each other; when the cutting edge of the bone cutting knife 5 descends into the cutting groove 7, the cutting edge of the bone cutting knife 5 moves down from between the two silicone pads 31, and the two silicone pads 31 are tightly pressed against the corresponding side walls of the bone cutting knife 5.

[0030] In this solution, the telescopic rod 4 drives the bone cutting knife 5 to move downward to cut the stick bone and then continue to move downward. The cutting edge of the bone cutting knife 5 passes through between the two silicone pads 31 and continues to move downward. During the downward movement of the bone cutting knife 5, the two silicone pads 31 are respectively pressed against the corresponding sides of the cutting knife until the liquid outlet 13 on the bone cutting knife 5 moves down to below the two silicone pads 31; when the bone marrow is blown away, the telescopic rod 4 drives the bone cutting knife 5 to move upward. During the upward movement of the bone cutting knife 5, the two silicone pads 31 slide relative to the side wall of the bone cutting knife 5, so as to facilitate the scraping of the bone marrow remaining on the side wall of the bone cutting knife 5 into the liquid collecting tank 14 below.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
