Description

Technical Field

[0001] This invention relates to the field of beef cattle breeding technology, and in particular to a mobile beef cattle breeding performance testing device. Background Technology

[0002] In the breeding of high-quality beef cattle, performance testing is an important step. The main performance tests for beef cattle include: 1. Body shape indicators: weight, height, waist circumference, and chest circumference; 2. Growth and development indicators: daily weight gain, body length, chest depth, and waist depth; 3. Muscle quality and meat trait indicators: backfat thickness and scapula length.

[0003] In existing technologies, most beef cattle performance tests are conducted using performance testing vehicles. However, due to the considerable height required for beef cattle performance testing, moving the cattle to these vehicles is quite difficult. Furthermore, most existing beef cattle performance testing vehicles involve placing the cattle directly on the vehicle body or strapping them directly to the vehicle. When the cattle are stimulated and experience a stress response during the testing process, the force exerted by the cattle's four hooves, which provide support, can easily injure the testers and damage the performance testing vehicle.

[0004] Therefore, it is necessary to provide a mobile beef cattle breeding performance testing device to solve the above-mentioned technical problems. Summary of the Invention

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0020] Please refer to the following: Figures 1-9In the first embodiment of the present invention, the mobile beef cattle breeding performance testing device includes: a base plate 1, on which multiple wheels are fixedly installed in a rectangular arrangement at the bottom; a first support frame 2 is fixedly installed on the top of the base plate 1, the width of the first support frame 2 being approximately 1.5m-2.0m. This width is designed to prevent beef cattle from turning around inside the first support frame 2 after entering it, thus facilitating the operator to test various performance parameters of the beef cattle within the first support frame 2; one side of the first support frame 2 is open; the main material of the first support frame 2 is square tubing; both the top and bottom of the first support frame 2 are open; and the first support frame 2 is welded to the base plate 1. A second support frame 3 is provided on the first support frame 2, the second support frame 3 comprising multiple rectangularly arranged square tubing and a top plate, such as... Figure 1 As shown, the square tube used in the second support frame 3 is welded to the first support frame 2. A first lifting mechanism 4 is provided at the top of the second support frame 3. A sling 5 is provided inside the first support frame 2. The sling 5 is used to support the cow's belly and lift the beef cattle. Extension mechanisms 6 are provided on both sides of the sling 5. The extension mechanisms 6 are used to extend or retract the width of the sling. Figure 5 As shown, when the sling 5 contacts the first support plate 16, or weighing plate 17, the width of the sling 5 is at its narrowest. This allows the cattle to easily enter the first support frame 2, ensuring the sling 5 is positioned directly below the cattle's abdomen. Simultaneously, it effectively reduces the chance of the sling being stepped on by the cattle, thus ensuring the sling 5 can properly lift the cattle. The extension mechanism 6 is connected to the first lifting mechanism 4. A conveyor belt 7 is fixedly installed on the top of the base plate 1, located within the first support frame 2. A connecting plate 8 is provided on the first support frame 2. One side of the connecting plate 8 is located outside the first support frame 2. The connecting plate 8 is designed to allow beef cattle to easily walk into the first support frame 2. When the end of the connecting plate 8 located outside the first support frame 2 is in contact with the ground, the tilt angle between the connecting plate 8 and the base plate 1 is controlled within 30 degrees. The first support frame 2 is provided with a storage mechanism 9, which is used to store the connecting plate 8. The second support frame 3 is equipped with a second lifting mechanism 10, which is adapted to the connecting plate 8 and the storage mechanism 9.

[0021] A first support plate 16 is fixedly installed inside the first support frame 2. The first support plate 16 has an installation groove. The top of the conveyor belt 7 is located within the installation groove. A weighing scale 17, fixedly connected to the base plate 1, is installed within the installation groove. The top of the weighing scale 17 is in contact with the conveyor belt 7. Figure 3 and Figure 4As shown, the weighing scale 17 is installed at the top center of the first support plate 16. The area occupied by the two sides of the first support plate 16 is relatively small. Therefore, when the beef cattle enter the first support frame 2, all four hooves of the beef cattle are directly above the weighing scale 17, which can ensure the accuracy of the weighing scale 17 in weighing the beef cattle. At the same time, the setting of the weighing scale 17 can improve the support strength of the conveyor belt 7. Before the beef cattle enter the first support frame 2, the weighing scale 17 is reset to zero, which can effectively avoid the influence of the conveyor belt 7 on the weight of the beef cattle. At the same time, when the beef cattle walk into the first support frame 2, the conveyor belt 7 can slowly start to adjust the relative position of the beef cattle and the lifting belt 5, so that the beef cattle can be lifted more conveniently and accurately.

[0022] The first lifting mechanism 4 includes a plurality of linearly distributed first mounting seats 401 fixedly installed on the top of the second support frame 3. A single first rotating shaft 402 is rotatably mounted on each of the plurality of first mounting seats 401. Two first winding reels 403 are symmetrically fixedly mounted on the first rotating shaft 402. A first rope 404 is fixedly wound around each of the first winding reels 403. Two first through holes are symmetrically opened on the top plate of the second support frame 3, and the first rope 404 passes through the first through holes. Figure 7 As shown, in this embodiment, the hole is round. In other embodiments, the first through hole can be set as a strip hole. The first rope 404 is fixedly connected to the extension mechanism 6. A first gear 405 is fixedly installed on the first rotating shaft 402. A first motor 406 is fixedly installed on the second support frame 3. A second gear 407 is fixedly installed on the output shaft of the first motor 406. The second gear 407 meshes with the first gear 405.

[0023] The same first lifting frame 14 is fixedly installed on the two first ropes 404, and the first ropes 404 are fixedly connected to the extension mechanism 6 through the first lifting frame 14. The extension mechanism 6 includes a sleeve 601 and a limiting post 606. The limiting post 606 is fixedly connected to the first support frame 2. Two sliders 602 are slidably installed inside the sleeve 601. A first spring 603 is fixedly installed between the two sliders 602. Support rods 604 are fixedly installed on the sides of the two sliders 602 that are far apart from each other. One end of the support rod 604 extends outside the sleeve 601 and is rotatably mounted with a lifting block 605. The limiting post 606 has a telescopic groove 607. Figure 5As shown, in this embodiment, the telescopic groove 607 is vertically arranged. In other embodiments, the telescopic groove 607 may be inclined, used to unfold or retract the sling 5 when the lifting block 605 moves within the telescopic groove 607. The lifting block 605 is slidably installed within the telescopic groove 607. One end of the second rope 608 is fixedly installed on each of the two lifting blocks 605 and the sleeve 601. The other ends of the three second ropes 608 are fixedly installed on the first lifting frame 14. The sleeve 601 and the lifting block 605 are detachably connected to the sling 5. Figure 6 As shown, both the sleeve 601 and the lifting block 605 have annular grooves. A connecting strip is fixedly installed in the annular groove. The connecting strip is detachably connected to the sling 5. The connecting strip has a protrusion with a locking hole. The sling 5 is equipped with a buckle that passes through the locking hole (not shown in the figure). Multiple collars can be set between the sleeve 601 and the lifting block 605. The collars are detachably connected to the sling 5 through the buckles. Then, the other end is fitted onto the outside of the support rod 604. This arrangement makes it easy to fold the sling 5.

[0024] The second lifting mechanism 10 includes two second mounting seats 1001 fixedly installed on the top of the second support frame 3. The same second rotating shaft 1002 is rotatably mounted on the two second mounting seats 1001. A second winding reel 1003 is fixedly mounted on the second rotating shaft 1002. A third rope 1004 is fixedly wound on the second winding reel 1003. A second motor 1005 is fixedly mounted on the second support frame 3. The output shaft of the second motor 1005 is fixedly connected to one end of the second rotating shaft 1002.

[0025] A second lifting frame 15 is fixedly installed on the two third ropes 1004. Through the second lifting mechanism 10, the second lifting frame 15 and the storage mechanism 9, after the beef cattle enter the first support frame 2, the connecting plate 8 can be automatically put into the storage mechanism 9, so that the first support frame 2 and the connecting plate 8 form a box that can "open a door", thereby preventing the beef cattle from moving out of the first support 2. The storage mechanism 9 includes two lifting slots 903, two first support blocks 901, and two second support blocks 902 formed on the first support frame 2. The two first support blocks 901 are rotatably mounted on both sides of the connecting plate 8, and slidably mounted on the lifting slots 903. The two second support blocks 902 are rotatably mounted on both sides of the connecting plate 8. Two arc-shaped slots 904 are symmetrically formed on the first support frame 2, with one side of each arc-shaped slot 904 being open. The second support blocks 902 are adapted to fit within the arc-shaped slots 904. Figure 1-2As shown, by setting two arc-shaped grooves 9, when the first support block 901 moves to the top of the lifting groove 903, the connecting plate 8 automatically rotates under its own weight, causing the second support block 902 to enter the arc-shaped groove 904, thus completing the storage of the connecting plate 8. Simultaneously, when the cattle try to move out of the first support frame 2 by backing up, they can only contact the connecting plate 8 through their rump. When the cattle's rump contacts the connecting plate 8, it is relatively close to the first support block 901. At this time, the force exerted by the cattle on the connecting plate 8 and the weight of the connecting plate 8, as well as... The lever formed by the two first support blocks 901 requires considerable force to rotate the connecting plate 8 around the first support blocks 901. Therefore, after the connecting plate 8 enters the storage mechanism 9, it can effectively prevent the beef cattle from moving out of the first support frame 2. In other embodiments, the height of the connecting plate 8 when it is placed vertically, i.e., the length of the connecting plate 8, can also be controlled so that the height of the connecting plate 8 and the first support frame 2 is slightly lower than the back of the beef cattle. One end of the fourth rope 905 is fixedly installed on the top of the first support block 901, and the other end of the fourth rope 905 is fixedly installed on the second lifting frame 15.

[0026] A storage box 13 is fixedly installed on the top of the base plate 1 on one side of the first support frame 2. The storage box 13 allows staff to conveniently store measuring tools for beef cattle performance and record books for recording beef cattle performance. A feeding trough 12 is fixedly installed on the top of the storage box 13 and is fixedly connected to the first support frame 2. The feeding trough 12 can easily lure beef cattle into the first support frame 2 and also soothe the beef cattle when they are being measured, thereby effectively reducing the beef cattle's fright during measurement. A moving mechanism 11 is fixedly installed on the bottom of the base plate 1. The moving mechanism 11 is used to move the base plate 1. In this embodiment, the moving mechanism 11 is a push handle, which can facilitate the movement of the entire device. In other embodiments, the moving mechanism 11 can be set as a hook, which can facilitate the movement of the entire device by hanging it on the rear of a vehicle.

[0027] The working principle of the mobile beef cattle breeding performance testing device provided by this invention is as follows: When it is necessary to test the performance of beef cattle: First, the entire device is moved to the entrance of the cattle shed by the moving mechanism 11. The lower end of the connecting plate 8 is moved out of the arc groove 904 by hand, and the connecting plate 8 is lowered by the second lifting mechanism 10 until the connecting plate 8 contacts the ground. The cattle to be measured are driven or lured into the first support frame 2 by grass. Then, the second motor 1005 is started. The second motor 1005 drives the second rotating shaft 1002 to rotate on the two second mounting seats 1001. The second rotating shaft 1002 drives the second winding reel 1003 to rotate. The second winding reel 1003 begins to wind up the third rope 1004. The third rope 1004 drives the second lifting frame 15 to move upward. The second lifting frame 15 drives the fourth rope 905 to move upward. The fourth rope 9015 drives the first support block 901 to move upward within the lifting groove 903. During this process, while one end of the connecting plate 8 moves upward, the other end of the connecting plate 8 moves upward at two... The first support block 901 rotates around its axis. When the top of the first support block 901 contacts the inner wall of the top of the lifting groove 903, the second support block 902 is directly in the arc groove 904. Under the gravity of the connecting plate 8 and the second support block 902, the connecting plate 8 continues to rotate around the first support block 901, and the second support block 902 enters the arc groove 904, thus completing the storage of the connecting plate 8. This prevents the cattle from moving out of the first support frame 2, thereby ensuring the normal measurement of the cattle. At this time, the weight of the cattle can be measured by weighing 17. When the cattle are fully inside the first support frame 2, the sling 5 is normally positioned between the cattle's front hooves and hind legs. To adjust the position of the sling 5 and better lift the cattle, simply start the conveyor belt 7 in either the forward or reverse direction, depending on the desired movement of the cattle. The conveyor belt 7 will then slowly move the cattle within the first support frame 2 until it reaches the desired position. Afterward, turn off the conveyor belt 7 and start the first motor 406. The first motor 406 drives the second gear 407 to rotate, which in turn drives the first gear 405 to rotate. The first gear 405 drives the first shaft 402 to rotate, which in turn drives the first reel 403 to rotate. The first reel 403 winds up the first rope 404, which in turn moves the first lifting frame 14 upward. The first lifting frame 14 then drives the first... The second rope 608 moves upward, driving the sleeve 601 and the lifting block 605 upward. This causes the lifting block 605 to move upward in the telescopic groove 607. When the lifting block 605 moves out of the telescopic groove 607, under the elastic force of the first spring 603, it pushes the two sliders 602 away from each other. The sliders 602 push the support rod 604 to move, and the support rod 604 drives the lifting block 605 to move until the sides of the two sliders 602 that are away from each other are in contact with the inner wall of the sleeve 601. The two lifting blocks 605, together with the collar, unfold the sling 5. Then, as the first motor 406 continues to start, the sling 5 moves upward until it contacts the belly of the beef cattle and lifts the beef cattle to the required height. At this point, the first motor 406 is turned off, and the various performance characteristics of the beef cattle can be tested.

[0028] After the inspection is completed, the first motor 406 is started in reverse to lower the cattle and press the two lifting blocks 605 together until they can be simultaneously placed into the corresponding telescopic grooves 607 and contact the bottom inner wall of the telescopic grooves 607. Then, the connecting plate 8 is rotated to move the second support block 902 out of the arc-shaped groove 904. Then, the second motor 1005 is started in reverse until the support plate 8 is in the position shown in the figure. Figure 1-2 When the state shown is reached, the sling 5 is then removed from the extension mechanism 6, and the conveyor belt 7 can be started in reverse. The beef cattle are then moved out by the slow movement of the conveyor belt 7.

[0029] Compared with related technologies, the mobile beef cattle breeding performance testing device provided by the present invention has the following beneficial effects: The mobile beef cattle breeding performance testing device provided by this invention, through the width setting of the first support frame 2, can prevent beef cattle from entering the first support frame 2 and turning around inside, thereby facilitating the lifting of beef cattle by the staff. At the same time, the first support frame 2 is designed to be hollow, which allows the staff to use tools such as measuring tapes to measure the body shape indicators, growth and development indicators, muscle quality and meat quality indicators of beef cattle. The conveyor belt 7 facilitates the entry and exit of beef cattle from the first support frame 2. The connecting plate 8 facilitates the entry and exit of beef cattle from the device. At the same time, the storage mechanism 9 and the second lifting mechanism 10 can easily close the first support frame 2, thereby preventing beef cattle from moving out of the device. The first lifting mechanism 4, the sling 5 and the extension mechanism 6 can easily lift the beef cattle, thereby raising the beef cattle's body off the ground, thus effectively avoiding stress reactions in the beef cattle that could cause significant damage to the entire device.

[0030] Second embodiment: Based on the mobile beef cattle breeding performance testing device provided in the first embodiment of this application, the second embodiment of this application proposes another mobile beef cattle breeding performance testing device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

The trigger alarm mechanism 1818 is used to control the second motor 1005 to start when the beef cattle enter the first support frame 2 and the beef cattle's front hooves step on the trigger alarm mechanism 1818, thereby lifting one end of the connecting plate 8 and finally erecting the connecting plate 8.

[0033] The trigger alarm mechanism 18 includes a first mounting box 1801 fixedly installed on the top of the weighing scale 17, a second mounting box 802 fixedly installed on the bottom inner wall of the first mounting box 1801, one end of a second spring 1803 fixedly installed on the bottom inner wall of the second mounting box 1802, a first insulating mounting block 1804 fixedly installed on the top of the second spring 1803, one end of a plurality of third springs 1807 fixedly installed on the bottom of the weighing scale 17, a second insulating mounting block 1808 fixedly installed on the other end of the third springs 1807, a slide rod 1809 fixedly installed on the top of the second insulating mounting block 1808, the slide rod 1809 passing through the weighing scale 17 and slidably connected to the weighing scale 17, and the same trigger plate 1810 fixedly installed on the top of the plurality of slide rods 1809, the trigger plate 1810 being located in the positioning groove; One of the second insulating mounting blocks 1808 is located inside the first mounting box 1801 and a second copper sheet 1806 is fixedly mounted thereon, and a second copper sheet 1805 is fixedly mounted on the first insulating mounting block 1804.

[0034] It also includes a power supply 20 and a switch 19. When the first copper sheet 1805 and the second copper sheet 1806 are in contact, the power supply 20, the switch 19, the second motor 1005, the first copper sheet 1805 and the second copper sheet 1806 form a closed circuit.

[0035] When the cattle enter the first support frame 2 and their front hooves step on the conveyor belt 7 directly above the trigger plate 1810, the trigger plate 1810 moves downward under the weight of the cattle. The trigger plate 1810 pushes the slide rod 1809 downward, which in turn pushes the second insulating mounting block 1808 downward, causing the third spring 1807 to move downward. The second insulating mounting block 1808 then pushes the second copper sheet 1806 downward until the second copper sheet 1806 contacts the first copper sheet 1805. At this point, the power supply 20, switch 19, second motor 1005, first copper sheet 1805, and second copper sheet 1806 form a closed loop. The second motor 1005 then starts, lifting the connecting plate 8 and finally placing it into the storage mechanism 9, thus automatically completing the automatic erection of the connecting plate 8. During this process, when the second copper sheet 1806... After the second copper plate 1806 contacts the first copper plate 1805, the second copper plate 1806 continues to push the first copper plate 1805 downward. The first copper plate 1805 pushes the first insulating mounting block 1804 downward, and the second spring 1803 is compressed until the bottom of the trigger plate 1810 contacts the weighing scale 17. At this time, the first copper plate 1805 and the second copper plate 1806 stop moving. In this process, the setting of the second spring 1803 and the second spring 1807 can play a good buffering role when the beef cattle step on the trigger alarm mechanism 8, thereby ensuring the normal service life of the trigger alarm mechanism 8. When the beef cattle step on the trigger plate 1810, simply turn off the switch 19, and the power supply 20 can be cut off to continue supplying power to the second motor 1005. At this time, the second motor 1005 can still continue to be controlled to rotate forward and backward according to the operation in the first embodiment.
