Description

Technical Field

[0001] The invention relates to the technical field of meat duck breeding systems, and in particular to a meat duck breast muscle thickness measurement and evaluation system and method. Background Art

[0002] In the broiler duck breeding system, the meat production of broiler ducks is an important economic trait to measure the production performance of broiler ducks, and is also an important indicator in breed breeding. When measuring and evaluating the meat production performance of broiler ducks, ultrasonic measurement methods are usually used to measure the breast muscle thickness of live broiler ducks to obtain breast muscle thickness data of broiler ducks.

[0003] When testing live ducks, the ducks are prone to movement, which affects the measurement of the duck's pectoral muscle thickness. Therefore, it is necessary to restrict the movement of the ducks to facilitate stable measurement. The prior art uses acupuncture to prick the duck's chest, and measures the acupuncture depth to obtain data on the duck's chest thickness. This method requires plucking the duck's feathers, and acupuncture the duck's chest muscles and bones, which can easily stimulate the duck to move violently, affecting the measurement of the duck's chest. The prior art uses manual pressing or using a restraint belt to restrain the duck, which has a poor restraining effect on the duck, is not conducive to maintaining the stability of the duck during testing, and is likely to cause damage to the duck. Summary of the invention

[0009] In the above-mentioned duck breast muscle thickness measurement and evaluation system, the electric chuck is electrically connected to a controller, and the controller is installed on a base. The electric chuck has two openings. When the electric chuck is working, it clamps and fixes the duck feet in the two openings. The controller is used to control the working state of the electric chuck.

[0010] In the above-mentioned duck breast muscle thickness measurement and evaluation system, the airbag assembly includes an air pump, which is installed on the side of a fixed frame, and the output end of the air pump is connected to a hose, and the end of the hose away from the air pump passes through a movable plate and is connected to a first airbag, and the top of the first airbag is fixedly connected to the bottom of the movable plate near the through-port and is located above the back of the duck in the fixed frame, and the top of the first airbag is connected to a connecting pipe, both ends of the connecting pipe pass through the top of the movable plate, and the end of the connecting pipe away from the first airbag is connected to a second airbag, and the top of the second airbag is fixedly connected to the bottom of the movable plate away from the through-port and is located above the tail end of the duck's wing in the fixed frame, and an electromagnetic valve is installed on the connecting pipe located above the movable plate.

A second sensor is installed in the second airbag, and the second sensor is used to detect the air pressure in the second airbag. The air pump, the first sensor, the second sensor and the solenoid valve are all electrically connected to the controller, and the controller is used to receive signals from the first sensor and the second sensor to control the working status of the air pump and the solenoid valve.

[0012] In the above-mentioned duck breast muscle thickness measurement and evaluation system, the toggle assembly includes an extrusion plate, a plurality of sliding cavities are opened in the fixed plate, a mounting plate is fixedly connected to the inside of the sliding cavity, the extrusion plate is slidably connected in the sliding cavity, and a spring is fixedly connected between the extrusion plate and the mounting plate, a sliding column is fixedly connected to the side of the extrusion plate away from the spring, the end of the sliding column away from the extrusion plate passes through the fixed plate, and is fixedly connected to a touch block, and the touch block rests on the breast of the duck away from the sliding column.

[0013] In the above-mentioned duck breast muscle thickness measurement and evaluation system, a hydraulic groove is provided in the sliding column, and a push column is fixedly connected to the side of the mounting plate close to the extrusion plate. The push column seals and penetrates the extrusion plate and the sliding column at one end away from the mounting plate, and slides in sealing cooperation with the hydraulic groove. A connecting cavity is provided in the touch block, and one side of the connecting cavity is connected to the hydraulic groove, and the other side is connected to a plurality of connecting holes. The plurality of connecting holes are connected to a rubber block on the side away from the connecting cavity. The rubber block protrudes from the touch block and rests on the breast of the duck.

[0014] In the above-mentioned duck breast muscle thickness measurement and evaluation system, the rubber block is elastic, and the plurality of rubber blocks are arranged horizontally.

[0015] In the above-mentioned duck breast muscle thickness measurement and evaluation system, the hydraulic tank contains hydraulic oil.

[0016] An evaluation method for a duck breast muscle thickness measurement evaluation system comprises the following steps:

[0017] S1: First, the inspector places the meat duck to be inspected into the interior of the fixed frame, and respectively places the feet of the meat duck into the two openings of the electric chuck. The electric chuck is controlled to restrict the feet of the meat duck and expose the breast of the meat duck from the opening of the fixed frame;

[0018] S2: The inspector drives the movable plate to rotate along the inner wall of the fixed frame through the handle, so that the two sets of movable plates are turned from a vertical state to a horizontal state, further limiting the activity space of the meat duck;

[0019] S3: Start the air pump, which delivers air to the inside of the first airbag through the hose, so that the first airbag is inflated and expanded until the lower end of the first airbag fits against the back of the duck; after the first sensor detects that the internal pressure of the first airbag reaches a predetermined threshold, the controller starts the solenoid valve to conduct, and part of the air inside the first airbag enters the second airbag through the connecting tube, so that the second airbag is inflated and expanded until the lower end of the second airbag contacts the end of the duck's wings; after the second sensor detects that the internal pressure of the second airbag reaches a predetermined threshold, the air pump is turned off, and the back and the end of the wings of the duck are squeezed by the inflated first and second airbags, so that the duck lifts its chest and exposes it largely through the opening;

[0020] S4: Start the electric slider 41, so that the electric slider 41 slides upward along the slide rail 4 and drives the fixed plate 42 to move synchronously. The synchronous movement of the fixed plate 42 drives the toggle assembly to move synchronously. During the upward movement of the toggle assembly, the feathers on the breast of the meat duck are pushed away;

[0021] S5: When the touch block 52 in the toggle assembly drives the multiple rubber blocks 54 to move upward and contact the breast of the meat duck, it is subject to the resistance of the breast of the meat duck, and the touch block 52 drives the slide column 51 and the extrusion plate 5 to squeeze the spring 45, and the push column 44 squeezes the hydraulic groove 53 in the slide column 51, so that the hydraulic oil in the hydraulic groove 53 is filled into the multiple rubber blocks 54 through the connecting cavity and the multiple connecting holes, so that the rubber blocks 54 expand and change from soft to hard. Since the breast of a male duck is often firmer than that of a female duck, and the feathers of a male duck are also harder than those of a female duck, when detecting a male duck, the sliding amplitude generated by the resistance of the breast of the meat duck when the slide column 51 moves upward will be larger than that of a female duck, making the rubber block 54 harder. When detecting a female duck, the rubber block 54 is relatively soft, thereby avoiding the hard rubber block from causing damage to the female duck and the soft rubber block from being unable to effectively push the feathers of the male duck apart;

[0022] S6: The detector works to detect the breast muscle thickness of the duck after the feathers are removed.

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] 1. The present invention sets a fixing mechanism, limits the activity space of the meat duck through a fixing frame and a rotatable movable plate, and limits and fixes the feet of the meat duck through an electric chuck. At the same time, the back and the end of the wings of the meat duck are squeezed by the airbag assembly, so that the meat duck straightens its chest and exposes its chest from the opening, thereby completing the restriction of the meat duck, facilitating the improvement of the stability of the meat duck during the subsequent detection operation of the thickness of the pectoral muscles of the meat duck, and improving the detection accuracy.

[0025] 2. The present invention arranges an airbag assembly. When the air pump is working, the first airbag is inflated through a hose. After the first airbag is inflated, it expands and squeezes the back of the duck. After the air pressure in the first airbag reaches a certain threshold, the solenoid valve is turned on, and part of the gas filled in the first airbag enters the second airbag through the connecting tube. After the second airbag is inflated, it expands and squeezes the end of the duck's wings, driving the duck's chest to stand up and expose the duck's chest largely through the opening, which is convenient for subsequent inspection. Since the airbag has a certain elasticity, it will not cause harm to the duck.

[0026] 3. The present invention sets a toggle mechanism. When the electric slider is working, it drives the fixed plate to move upward on the slide rail. When the fixed plate moves, it drives the toggle assembly to move synchronously. The output end of the toggle assembly moves upward from the bottom of the duck's chest, thereby squeezing and pushing aside the duck's feathers, making it convenient for the detector to detect the thickness of the duck's pectoral muscles and improving the detection effect.

[0027] 4. The present invention arranges a toggle assembly. When the toggle assembly moves upward, the touch block drives the multiple rubber blocks to move upward and contact the breast of the meat duck. When the touch block drives the sliding column and the extrusion plate to squeeze the spring, the push column squeezes the hydraulic groove in the sliding column, so that the hydraulic oil in the hydraulic groove is filled into the multiple rubber blocks through the connecting cavity and the multiple connecting holes, so that the rubber blocks expand and change from soft to hard. Since the breast of a drake duck is often firmer than that of a female duck, and the feathers of a drake duck are also harder than those of a female duck, when detecting a drake duck, the sliding amplitude generated by the resistance of the breast of the meat duck when the sliding column moves upward will be larger than that of a female duck, making the rubber block harder. When detecting a female duck, the rubber block is relatively soft, thereby avoiding the hard rubber block from causing damage to the female duck and the soft rubber block from being unable to effectively push aside the feathers of the drake duck, thereby improving the subsequent detection effect.

[0049] Reference Fig. 9 and Fig.10 The toggle assembly includes an extrusion plate 5, a plurality of sliding cavities are opened in the fixed plate 42, a mounting plate 43 is fixedly connected inside the sliding cavity, the extrusion plate 5 is slidably connected in the sliding cavity, and a spring 45 is fixedly connected between the extrusion plate 5 and the mounting plate 43, a sliding column 51 is fixedly connected to the side of the extrusion plate 5 away from the spring 45, the sliding column 51 passes through the fixed plate 42 at one end away from the extrusion plate 5, and is fixedly connected to a touch block 52, and the touch block 52 is against the breast of the meat duck at the side away from the sliding column 51.

[0050] A hydraulic groove 53 is provided in the sliding column 51, and a push column 44 is fixedly connected to the side of the mounting plate 43 close to the extrusion plate 5. The push column 44 seals and penetrates the extrusion plate 5 and the sliding column 51 at one end away from the mounting plate 43, and slides in a sealed manner with the inside of the hydraulic groove 53. A connecting cavity is provided in the touch block 52, and one side of the connecting cavity is connected to the hydraulic groove 53, and the other side is connected to multiple connecting holes. The multiple connecting holes are connected to rubber blocks 54 on the side away from the connecting cavity. The rubber block 54 protrudes from the touch block 52 and rests on the breast of the meat duck.

[0051] The rubber block 54 is elastic, and a plurality of rubber blocks 54 are arranged horizontally.

[0052] The hydraulic tank 53 contains hydraulic oil.

[0053] An evaluation method for a duck breast muscle thickness measurement evaluation system comprises the following steps:

[0054] S1: First, the inspector places the meat duck to be inspected into the interior of the fixing frame 2, and respectively places the feet of the meat duck into the two openings of the electric chuck 21. The electric chuck 21 is controlled to restrict the feet of the meat duck and expose the breast of the meat duck from the opening of the fixing frame 2.

[0055] S2: The inspector drives the movable plate 22 to rotate along the inner wall of the fixed frame 2 through the handle 23, so that the two sets of movable plates 22 are turned from a vertical state to a horizontal state, further limiting the activity space of the meat duck;

[0056] S3: Start the air pump 3, and the air pump 3 delivers air to the inside of the first airbag 32 through the hose 31, so that the first airbag 32 is inflated and expanded until the lower end of the first airbag 32 fits against the back of the duck; after the first sensor 33 detects that the internal pressure of the first airbag 32 has reached a predetermined threshold, the controller will start the solenoid valve 37 to conduct, and part of the air inside the first airbag 32 will enter the second airbag 34 through the connecting tube 36, so that the second airbag 34 is inflated and expanded until the lower end of the second airbag 34 contacts the end of the duck's wing; after the second sensor 35 detects that the internal pressure of the second airbag 34 has reached a predetermined threshold, the air pump 3 is turned off, and the inflated first airbag 32 and second airbag 34 squeeze the duck's back and the end of its wings, so that the duck lifts its chest and exposes it largely through the opening;

[0057] S4: Start the electric slider 41, so that the electric slider 41 slides upward along the slide rail 4 and drives the fixed plate 42 to move synchronously. The synchronous movement of the fixed plate 42 drives the toggle assembly to move synchronously. During the upward movement of the toggle assembly, the feathers on the breast of the meat duck are pushed away;

[0058] S5: When the touch block 52 in the toggle assembly drives the multiple rubber blocks 54 to move upward and contact the breast of the meat duck, it is subject to the resistance of the breast of the meat duck, and the touch block 52 drives the slide column 51 and the extrusion plate 5 to squeeze the spring 45, and the push column 44 squeezes the hydraulic groove 53 in the slide column 51, so that the hydraulic oil in the hydraulic groove 53 is filled into the multiple rubber blocks 54 through the connecting cavity and the multiple connecting holes, so that the rubber blocks 54 expand and change from soft to hard. Since the breast of a male duck is often firmer than that of a female duck, and the feathers of a male duck are also harder than those of a female duck, when detecting a male duck, the sliding amplitude generated by the resistance of the breast of the meat duck when the slide column 51 moves upward will be larger than that of a female duck, making the rubber block 54 harder. When detecting a female duck, the rubber block 54 is relatively soft, thereby avoiding the hard rubber block from causing damage to the female duck and the soft rubber block from being unable to effectively push the feathers of the male duck apart;

[0059] S6: The detector works to detect the breast muscle thickness of the duck after the feathers are removed.

[0060] In the present invention, when the breast muscle thickness of a meat duck needs to be measured, the inspector puts the meat duck to be inspected into the interior of the fixing frame 2, and then puts the feet of the meat duck into the two openings of the electric chuck 21 respectively. After the insertion is completed, the controller is started to open the electric chuck 21. The electric chuck 21 contracts by pushing the three groups of card blocks inside, thereby restricting the feet of the meat duck, so that the meat duck will not move around during the inspection process to affect the inspection results;

[0061] After the duck's feet are restrained, the inspector drives the movable plate 22 to rotate along the inner wall of the fixed frame 2 through the handle 23, so that the two sets of movable plates 22 are rotated from a vertical state to a horizontal state, further restricting the duck's activity space;

[0062] After the two sets of movable plates 22 close the upper end of the fixing frame 2, the air pump 3 is started, and the air pump 3 works to deliver air to the inside of the first air bag 32 through the hose 31, so that the first air bag 32 is inflated and expanded until the lower end of the first air bag 32 is in contact with the back of the duck;

[0063] At this time, the first airbag 32 cannot continue to expand under the restriction of the duck, which will cause the internal pressure of the first airbag 32 to increase sharply. At this time, the first sensor 33 inside the first airbag 32 will detect the change of the internal pressure of the first airbag 32. After the air pressure in the first airbag 32 reaches a predetermined threshold, the first sensor 33 will send a signal to the controller, and the controller will start the solenoid valve 37. At this time, the solenoid valve 37 is opened, so that the connecting pipe 36 remains unobstructed in one direction;

[0064] At this time, part of the air in the first airbag 32 will enter the second airbag 34 through the connecting tube 36, so that the first airbag 32 will not exert a large pressure on the inside of the duck, and the second airbag 34 will be inflated and expanded until the lower end of the second airbag 34 contacts the end of the duck's wing.

[0065] At this time, the second airbag 34 cannot continue to expand under the restriction of the meat duck, which will cause the internal pressure of the second airbag 34 to increase sharply. At this time, the second sensor 35 in the second airbag 34 will detect the change in the internal pressure of the second airbag 34, and the threshold of the signal sent by the second sensor 35 is greater than that of the first sensor 33, so that the internal pressure of the second airbag 34 is greater than that of the first airbag 32, and the squeezing force of the second airbag 34 on the meat duck is greater than that of the first airbag 32. At this time, the meat duck will feel uncomfortable, and the meat duck will raise its chest to adapt to the pressure generated by the second airbag 34, so that the meat duck's chest can be largely exposed through the opening during the inspection, and because the airbag has a certain elasticity, it will not cause harm to the meat duck, which is convenient for subsequent inspections;

[0066] After the meat duck raises its chest, the electric slider 41 is started, so that the electric slider 41 slides upward along the inner wall of the slide rail 4 and drives the fixed plate 42 to move synchronously. The upward movement of the fixed plate 42 drives several touch blocks 52 to move synchronously through the slide column 51. Since the touch block 52 is under the breast of the meat duck, when the touch block 52 moves upward, it will contact the breast of the meat duck. At this time, the touch block 52 will be squeezed by the meat duck to generate thrust, so that the touch block 52 drives the slide column 51 to shrink along the sliding cavity of the fixed plate 42. The shrinkage of the slide column 51 will squeeze the spring 45 through the squeezing plate 5. At the same time, when the slide column 51 shrinks, its inner wall will slide along the outer wall of the push column 44, so that the push column 44 pushes the hydraulic oil in the hydraulic groove 53, so that the hydraulic oil in the hydraulic groove 53 enters the interior of the multiple rubber blocks 54 through the connecting cavity and multiple connecting holes on the touch block 52;

[0067] At this time, after the rubber block 54 is filled with hydraulic oil, its internal pressure increases, thereby causing the rubber block 54 to expand and harden from soft, so that when the rubber block 54 contacts the breast of the meat duck, the feathers on the breast of the meat duck are pushed aside. At the same time, since the breast of a male duck is often firmer than that of a female duck, and the feathers of a male duck are also harder than those of a female duck, when detecting a male duck, the sliding amplitude of the sliding column 51 will be larger than that of a female duck, making the rubber block 54 harder. When detecting a female duck, the rubber block 54 is relatively soft, thereby preventing the hard rubber block 54 from causing damage to the female duck and preventing the soft rubber block 54 from effectively pushing aside the feathers of the male duck, thereby improving the subsequent detection effect;

[0068] After the feathers on the breast of the meat duck are pushed aside, the detector 11, i.e., the veterinary B-ultrasound machine, detects the thickness of the breast muscles of the meat duck to complete the detection of the thickness of the breast muscles of the meat duck.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

10. An evaluation method using the duck breast muscle thickness measurement and evaluation system according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: First, the inspector places the meat duck to be inspected into the interior of the fixing frame (2), and respectively places the feet of the meat duck into the two openings of the electric chuck (21). The electric chuck (21) is controlled to restrict the feet of the meat duck and expose the breast of the meat duck from the opening of the fixing frame (2); S2: The inspector drives the movable plate (22) to rotate along the inner wall of the fixed frame (2) through the handle (23), so that the two sets of movable plates (22) are turned from a vertical state to a horizontal state, further limiting the movement space of the meat duck; S3: Start the air pump (3), and the air pump (3) delivers air to the inside of the first air bag (32) through the hose (31), so that the first air bag (32) is inflated and expanded until the lower end of the first air bag (32) fits against the back of the duck; after the first sensor (33) detects that the internal pressure of the first air bag (32) reaches a predetermined threshold, the controller starts the solenoid valve (37) to conduct, and part of the air inside the first air bag (32) enters the second air bag (34) through the connecting pipe (36), so that the second air bag (34) is inflated and expanded until the lower end of the second air bag (34) contacts the end of the duck's wing; after the second sensor (35) detects that the internal pressure of the second air bag (34) reaches a predetermined threshold, the air pump (3) is turned off, and the inflated first air bag (32) and the second air bag (34) are used to squeeze the duck's back and the end of its wings, so that the duck lifts its chest and exposes it largely through the opening; S4: starting the electric slider (41), so that the electric slider (41) slides upward along the slide rail (4) and drives the fixed plate (42) to move synchronously, and the synchronous movement of the fixed plate (42) drives the toggle assembly to move synchronously, and the toggle assembly moves upward to push away the feathers on the breast of the meat duck; S5: When the touch block (52) in the toggle assembly drives the plurality of rubber blocks (54) to move upward and contact the breast of the meat duck, the touch block (52) drives the slide column (51) and the extrusion plate (5) to squeeze the spring (45), and causes the push column (44) to squeeze the hydraulic groove (53) in the slide column (51), so that the hydraulic oil in the hydraulic groove (53) is filled into the plurality of rubber blocks (54) through the connecting cavity and the plurality of connecting holes, so that the rubber blocks (54) expand and change from soft to hard. Since the breast of a male duck is often firmer than that of a female duck, and the feathers of a male duck are also harder than those of a female duck, when detecting a male duck, the sliding amplitude generated by the resistance of the breast of the meat duck when the slide column (51) moves upward will be larger than that of a female duck, making the rubber block (54) harder. When detecting a female duck, the rubber block (54) is relatively soft, thereby preventing the hard rubber block from causing damage to the female duck and the soft rubber block from being unable to effectively push the feathers of the male duck apart. S6: The detector (11) works to detect the thickness of the breast muscle of the duck after the feathers are removed.
