Description

Technical Field

[0001] The present invention relates to the technical field of pork detection equipment, and particularly to a pork shear force measuring instrument. Background Art

[0002] The main protein source for humans is animal protein, and pork accounts for the largest proportion in meat consumption, accounting for about 40% of the global meat consumption. With the growth of the population and the increase in the average household income, both the global per capita pork consumption and the total pork consumption are on the rise. At the present stage, people's demand for pork has gradually shifted from quantity-based to quality-based. Pork shear force is one of the main indicators reflecting pork quality and is closely related to the appearance, juiciness, flavor and tenderness of pork. A pork shear force measuring instrument is an instrument that measures relevant data by the force obtained from shearing pork.

[0003] In the prior art, a patent document with the application number CN201820796401.6 and the authorization announcement date of December 4, 2018 discloses a pork shear force measuring device, including a control box. A placement box is fixedly connected to the top of the control box. An opening is provided at the top of the placement box. Through holes are provided on both the left and right sides of the placement box. The inner wall of the control box is movably connected through a threaded rod. Threaded tubes are threadedly connected to both the left and right sides of the outer surface of the threaded rod. Connecting rods are fixedly connected to the tops of the two threaded tubes. Clamping blocks are fixedly connected to the opposite ends of the connecting rods corresponding to the through holes. A driven bevel gear is threadedly connected to the outer surface of the threaded rod and on the right side of the right threaded tube.

[0028] Next, in combination with the accompanying drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0029] Embodiment 1:

[0030] Combined with Figures 1-4, a pork shear force measuring instrument according to this embodiment includes a machine base 1. Above the machine base 1, there is a workbench 2. In the middle of the workbench 2, there is an installation hole. Inside the installation hole, there is a driving disk 3 rotatably connected. On the driving disk 3, there is a driving component for connecting the workbench 2. On the outer side of one end of the workbench 2, there is a shear force tester 4 installed on the machine base 1. At the other end of the workbench 2, there is a feeding component. The driving component includes a plurality of clamping blocks 10 hinged on the driving disk 3. Along the circumferential direction, a plurality of clamping grooves 11 engaged with the clamping blocks 10 are provided on the inner wall of the installation hole. On one side of the clamping block 10, there is an installation column 12 fixed on the driving disk 3. On the installation column 12, there is a return spring 13 fixed on the adjacent clamping block 10. On the top of the driving disk 3, there is a feeding rod 14 slidably matched with the tabletop of the workbench 2. At one end of the workbench 2, there is a discharge port 15 matched with the feeding rod 14. Below the workbench 2, there is a loading block 20 slidably connected to the machine base 1. Inside the loading block 20, there is a receiving box 21 slidably connected. At the bottom of the driving disk 3, there is a worm 16 rotatably connected to the machine base 1. On the machine base 1, there is a driving shaft rotatably connected. On the outer side of the driving shaft, there is a worm gear fixedly sleeved and engaged with the worm 16. On the machine base 1, there is a rotating shaft rotatably connected. On the outer walls of the driving shaft and the rotating shaft, there are transmission wheels fixedly sleeved. Outside the transmission wheels, there is a transmission belt. The transmission wheels and the transmission belt are in transmission cooperation. On the outer wall of the rotating shaft, there is a semi-gear 18 fixedly sleeved. Outside the semi-gear 18, there is a linkage frame 17 sleeved. On the inner walls of both sides of the linkage frame 17, there are teeth engaged with the semi-gear 18. At both ends of the linkage frame 17, there are connecting columns 19. The connecting column 19 near one end of the loading block 20 is fixed on the loading block 20. On the bottom of the workbench 2, there is an annular groove. Inside the annular groove, there is a connecting ring 9 slidably connected. At the bottom of the connecting ring 9, there are a plurality of support columns fixed on the machine base 1. The support columns slide inside the notch of the annular groove. Inside the machine base 1, there is a motor. The motor is a forward and reverse motor. The output end of the motor is in transmission connection with one end of the driving shaft. At the bottom of the loading block 20, there is a sliding block 22. On the machine base 1, there is a sliding groove 23 slidably matched with the sliding block 22. The receiving box 21 corresponds to the discharge port 15.

[0031] The workbench 2 is of a circular structure. Along the circumferential direction, the workbench 2 is provided with a plurality of material placement grooves with the driving disk 3 as the axis. The material placement grooves correspond to the cutting knives of the shear force tester 4. Through the material placement grooves corresponding to the cutting knives of the shear force tester 4, the cutting knives of the shear force tester 4 can quickly shear and process the pork in the material placement grooves.

[0032] The support columns are provided with stable holes. The connecting column 19 at the end far from the loading block 20 slides inside the stable holes. Through the sliding cooperation between the stable holes and the connecting column 19, the stability performance of the linkage frame 17 can be effectively improved.

[0033] In the embodiment of the present application, the implementation principle of a pork shear force tester is as follows: Through the operation of the motor, the drive shaft is driven to rotate, and the worm gear is driven to rotate. Through the meshing of the worm gear and the worm 16, the drive disk 3 is driven to rotate counterclockwise. At this time, the workbench 2 can be driven to rotate by the counterclockwise rotating drive disk 3. At this time, the pork on the workbench 2 can be driven to rotate by the rotating workbench 2. When the pork rotates to the bottom of the cutter of the shear force tester 4, the pork can be measured by the operation of the shear force tester 4 at this time. After the measurement of a piece of pork is completed, the motor continues to operate at this time, driving the next piece of unmeasured pork to rotate to the bottom of the cutter of the shear force tester 4, and the pork is measured continuously at this time. After all the pork has been measured, by the reverse operation of the motor, the drive disk 3 is driven to rotate clockwise. At this time, the rotating drive disk 3 will drive the material pushing rod 14 to rotate. At this time, the cut pork on the workbench 2 can be swept by the rotating material pushing rod 14. At this time, the swept pork will enter the inside of the discharge port 15 and fall into the inside of the receiving box 21 through the discharge port 15, and the receiving box 21 is used to collect the measured pork.

[0034] And when the drive shaft rotates, through the transmission cooperation of the transmission wheel and the transmission belt, the rotating shaft and the half gear 18 will be driven to rotate. At this time, the linkage frame 17 can be driven to reciprocate by the rotating half gear 18. At this time, the connecting column 19 can be driven to reciprocate by the reciprocating linkage frame 17, driving the loading block 20 and the receiving box 21 to reciprocate. At this time, the pork inside the receiving box 21 can be driven to shake by the reciprocating receiving box 21, leveling the pork inside the receiving box 21 and increasing the capacity of the receiving box 21.

[0035] Embodiment 2:

[0036] Combined with Figures 5-7, on the basis of Embodiment 1, the further improvement of this embodiment lies in that the feeding assembly includes a housing 5 fixed on the machine base 1. The housing 5 is provided with a material placement cavity 6 and a working cavity 7. The inner wall between the material placement cavity 6 and the working cavity 7 is provided with a sliding groove. A plurality of material placement plates 24 are slidably connected inside the sliding groove. The pork can be carried by the material placement plates 24. By using the material placement plates 24 that carry the pork at intervals, it is possible to prevent multiple pieces of pork from sticking together, thereby effectively improving the discharging speed and endurance of the equipment. At the bottom of the lowermost material placement plate 24, there is a push block 25 that slides inside the sliding groove. On one side of the material placement plate 24 close to the push block 25, there is a guiding groove 27. A guiding block 26 that slides inside the guiding groove 27 is fixed on the push block 25. A linkage block 28 is hinged on the inner wall of the guiding groove 27. One end of the housing 5 close to the workbench 2 is fixed with a guiding plate. The guiding plate is provided with a guiding hole. Above the guiding plate, there is a discharging groove opened on the housing 5. A driving plate 8 is slidably connected inside the working cavity 7. The push block 25 is fixed on the driving plate 8. A plurality of hydraulic cylinders 30 with piston ends fixed on the driving plate 8 are fixed on the inner wall of the working cavity 7. The driving plate 8 is provided with a sliding opening 29 that slidably cooperates with the material placement plate 24. The bottom of the housing 5 is provided with a conveying plate opening 31 that communicates with the working cavity 7. On the top of the machine base 1, there is a receiving plate box 32. The receiving plate box 32 is a box with an upward opening. The opening of the receiving plate box 32 corresponds to the conveying plate opening 31. By the operation of the hydraulic cylinder 30, the piston end of the hydraulic cylinder 30 is driven to displace, and the driving plate 8 is driven to displace. At this time, the push block 25 can be driven to displace by the displaced driving plate 8. At this time, the pork can be pushed to displace by the displaced push block 25. When the pork falls on the guiding plate through the discharging groove, at this time, the displaced push block 25 will push the pork on the guiding plate into the guiding hole. At this time, the pork that falls into the guiding hole will fall on the workbench 2. At this time, the workbench 2 can carry the pork that has not been measured.

[0037] And when the conveying of one piece of pork is completed, at this time, the hydraulic cylinder 30 operates, driving the piston end of the hydraulic cylinder 30 to contract, driving the driving plate 8 and the push block 25 to reset. At this time, the reset push block 25 will pull the material placement plate 24 to reset. When the material placement plate 24 enters the working cavity 7, at this time, by the operation of the hydraulic cylinder 30, the piston end of the hydraulic cylinder 30 is driven to displace, driving the driving plate 8 to displace, and driving the push block 25 to displace. When the material placement plate 24 on the push block 25 passes through the sliding opening 29, at this time, the material placement plate 24 on the push block 25 will fall into the conveying plate opening 31 and enter the receiving plate box 32. At this time, the receiving plate box 32 can receive the material placement plate 24. And when the material placement plate 24 inside the material placement cavity 6 enters the working cavity 7, at this time, the pork and the material placement plate 24 above the lowermost material placement plate 24 inside the material placement cavity 6 will fall into the material placement cavity 6. When the guiding block 26 on the displaced push block 25 enters the guiding groove 27 on the adjacent material placement plate 24, the feeding work can continue.

[0038] A movable door is hinged to the outside of the housing 5. The movable door is communicated with the material placing cavity 6 and the working cavity 7. By opening the movable door, it is convenient for the staff to place the pork inside the material placing cavity 6.

[0039] Working principle: Through the operation of the hydraulic cylinder 30, the piston end of the hydraulic cylinder 30 is driven to displace, driving the driving plate 8 to displace. At this time, the pushing block 25 can be driven to displace by the displaced driving plate 8. At this time, the pushing block 25 in displacement can push the pork to displace. When the pork falls on the guide plate through the discharge chute, the pushing block 25 in displacement at this time will push the pork on the guide plate into the inside of the guide hole. At this time, the pork falling into the guide hole will fall on the workbench 2. Then, through the operation of the hydraulic cylinder 30, the piston end of the hydraulic cylinder 30 is driven to contract, driving the driving plate 8 and the pushing block 25 to reset. At this time, the reset pushing block 25 will pull the material placing plate 24 to reset. When the material placing plate 24 enters the inside of the working cavity 7, at this time, through the operation of the hydraulic cylinder 30, the piston end of the hydraulic cylinder 30 is driven to displace, driving the driving plate 8 to displace, and driving the pushing block 25 to displace. When the material placing plate 24 on the pushing block 25 passes through the sliding port 29, the material placing plate 24 on the pushing block 25 will fall into the inside of the plate conveying port 31 and enter the inside of the plate receiving box 32. At this time, the plate receiving box 32 can receive the material placing plate 24. And when the material placing plate 24 in the material placing cavity 6 enters the inside of the working cavity 7, the pork and the material placing plate 24 above the material placing plate 24 at the bottom of the material placing cavity 6 will fall into the inside of the material placing cavity 6. When the guiding block 26 on the displacing pushing block 25 enters the inside of the guiding groove 27 on the adjacent material placing plate 24, the feeding work can continue. After the pork is placed, through the operation of the motor, the driving shaft is driven to rotate, driving the worm gear to rotate. Through the meshing of the worm gear and the worm 16, the driving disc 3 is driven to rotate counterclockwise. At this time, the workbench 2 can be driven to rotate by the counterclockwise rotating driving disc 3. At this time, the pork on the workbench 2 can be driven to rotate by the rotating workbench 2. When the pork rotates to the bottom of the cutter of the shear force tester 4, the pork can be measured through the operation of the shear force tester 4. After one piece of pork is measured, at this time, the motor continues to operate, driving the next piece of unmeasured pork to rotate to the bottom of the cutter of the shear force tester 4, and at this time, the pork is continuously measured. After all the pork is measured, through the reverse operation of the motor, the driving disc 3 is driven to rotate clockwise. At this time, the rotating driving disc 3 will drive the material pushing rod 14 to rotate. At this time, the cut pork on the workbench 2 can be swept by the rotating material pushing rod 14. At this time, the swept pork will enter the inside of the discharge port 15 and fall into the inside of the material receiving box 21 through the discharge port 15. The measured pork is collected through the material receiving box 21. And when the driving shaft rotates, through the transmission cooperation of the transmission wheel and the transmission belt, the rotating shaft and the half gear 18 will be driven to rotate. At this time, the linkage frame 17 can be driven to reciprocate by the rotating half gear 18. At this time, the connecting column 19 can be driven to reciprocate by the reciprocating linkage frame 17, driving the loading block 20 and the material receiving box 21 to reciprocate.At this time, the reciprocating displacement of the material receiving box 21 can drive the pork inside the material receiving box 21 to vibrate, level the pork inside the material receiving box 21, and improve the capacity of the material receiving box 21.

[0040] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
