Description

Technical Field

[0001] This invention relates to the field of pig breeding technology, and in particular to a device for measuring the growth and fattening performance of pigs. Background Technology

[0002] From the end of the nursery period, pigs to be selected for growth and fattening performance testing undergo initial selection. Selected individuals must be healthy, free of genetic defects (cryptorchidism, inguinal canthus, etc.), have normal growth and development, and conform to breed characteristics in body shape and appearance. The standard for the number of pigs for fattening performance testing is to ensure that each litter has two boars and three sows before the end of the nursery period, and one boar and two sows per litter at the end of the testing (if conditions permit, whole-herd testing can be conducted). Boars are tested in individual pens or using an automated boar performance testing device, while sows are tested in small groups. During testing, pigs have free access to feed and water. Test indicators include daily weight gain, feed conversion ratio, and age at which the pig reaches 75 kg.

[0003] In the prior art, most automatic performance testing devices for breeding pigs include a frame, a weighing mechanism, a feeding mechanism, and a weighing mechanism. For example, Chinese Patent [Publication No.: CN108617539B] discloses a closed intelligent breeding pig testing station, which includes a frame, a weighing pen, a feeding device, and a weighing device. The weighing pen is connected to the frame through multiple first weighing sensors. An antenna plate and a controller are installed inside the frame. The antenna plate collects information about the breeding pigs, and the controller communicates with a host computer. The first weighing sensors, the second weighing sensors, and the antenna plate transmit the monitored signals to the controller, which controls the feeding device.

[0004] However, most current testing devices only have a single opening. Breeding pigs enter the device through this opening, and after the test, they exit by backing out. In practice, this method of exiting the device backwards is inconvenient, as the pigs tend to remain inside for extended periods, hindering the entry of subsequent breeding pigs. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a growth and fattening performance testing device for breeding pigs, which solves the problem in the prior art that breeding pigs exit the testing device from the opening by backing away, which is inconvenient and that breeding pigs tend to stay in the testing device for a long time, affecting the entry of subsequent breeding pigs.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] A growth and fattening performance testing device for breeding pigs includes a frame, a weighing mechanism, a feeding mechanism, and a weighing mechanism. One end of the frame has an opening, the weighing mechanism is located at the bottom of the frame, and the feeding mechanism and the weighing mechanism are located at the end of the frame away from the opening. One side of the frame has an outlet, and a sealing plate is provided in the outlet. The top of the sealing plate is rotatably connected to the frame. A first driving component is provided in the frame, which is used to drive the sealing plate to rotate.

[0008] By setting up the above structure, after the test is completed in the testing device, the first drive component is controlled to drive the sealing plate to rotate, opening the outlet on one side of the frame. The breeding pig can leave the testing device from the outlet without having to exit the testing device by backing up, effectively reducing the situation where the breeding pig stays in the testing device for a long time.

[0009] Furthermore, a push plate is provided on the side of the frame away from the sealing plate. The push plate is slidably installed in the frame along the width direction of the frame. A second driving component is provided in the frame. The second driving component is used to drive the push plate to move along the width direction of the frame. When the push plate moves along the width direction of the frame, the push plate drives the breeding pigs in the frame toward the exit side.

[0010] By setting up the above structure, when the outlet is opened, the second drive component is controlled to drive the push plate to move towards the outlet. The push plate drives the breeding pigs in the frame toward the outlet side, effectively preventing the breeding pigs from staying in the measuring device.

[0011] Furthermore, the lower surface of the push plate is separated from the upper surface of the weighing mechanism. When the push plate moves along the width direction of the frame, it scrapes away debris from the weighing mechanism.

[0012] By setting up the above structure, when the push plate moves along the width of the frame, the push plate scrapes away feces, urine and other debris on the weighing mechanism and removes the debris from the weighing mechanism, thus preventing debris from remaining on the weighing mechanism and affecting the accuracy of the weighing mechanism.

[0013] Furthermore, the first driving component includes a driving plate, the end of which is fixedly connected to a push plate away from the sealing plate. The driving plate is located below the rotating shaft of the sealing plate. When the driving plate moves toward the sealing plate, it pushes the sealing plate to rotate and open.

[0014] By setting up the above structure, the push plate moves, driving the drive plate to move, and the drive plate pushes the sealing plate to rotate and open. There is no need to set up an additional drive structure, which effectively reduces the operation steps and lowers the cost.

[0015] Furthermore, the first driving assembly also includes a driving column. A slot is provided on the sealing plate at the position corresponding to the driving plate. The driving column is fixedly installed in the slot. The axis of the driving column and the rotation axis of the sealing plate are on the same straight line. The height of the slot is greater than the length of the driving plate. A missing gear is fixedly provided on the outer circumference of the driving column. The missing gear is located on the side close to the push plate. The driving plate is configured as a rack. The rack meshes with the missing gear.

[0016] By configuring the above structure, as the drive plate moves towards the sealing plate, the rack on the drive plate drives the missing gear to rotate. The missing gear, through the drive column, drives the sealing plate from the closed state to the open state, until the missing gear disengages from the rack. This allows the sealing plate to open after the drive plate has moved a short distance, facilitating the rapid exit of the breeding pigs from the testing device. After the drive plate stops at its maximum position, the weight of the sealing plate causes the missing gear to rotate towards the rack, re-engaging it with the rack. During the retraction of the sealing plate, the rack on the drive plate drives the missing gear to rotate. The missing gear, through the drive column, drives the sealing plate from the open state to the closed state, until the missing gear disengages from the rack. This allows the sealing plate to close after the drive plate has moved a short distance back, effectively preventing breeding pigs from entering the testing device from the exit.

[0017] Furthermore, the second drive assembly includes a drive motor and a screw. The frame has a mounting plate above the push plate along the width direction of the frame. The mounting plate has a mounting groove along the length direction of the mounting plate. The top of the push plate has a mounting ear, which is slidably installed in the mounting groove. The screw is arranged along the length direction of the mounting plate. Both ends of the screw are rotatably connected to the frame. The mounting ear is threaded onto the screw. The drive motor is fixedly connected to the frame and is drively connected to the screw.

[0018] By setting up the above structure, the transmission connection between the second drive component and the push plate is achieved.

[0019] Furthermore, a side plate is provided on the side of the push plate away from the sealing plate. The side plate is fixedly connected to the frame and is used to close the side of the frame away from the sealing plate.

[0020] By setting up the above structure, the side of the frame away from the sealing plate is closed, preventing the breeding pig from entering the measuring device from the side of the frame away from the sealing plate during the process of the push plate moving towards the sealing plate.

[0021] Furthermore, a support plate is provided above the drive plate in the frame, and a connecting rod is fixedly installed on the lower surface of the support plate near the push plate. A sliding groove is provided on the upper surface of the drive plate, and a limiting head is provided at the free end of the connecting rod. The limiting head is slidably locked in the sliding groove and is used to restrict the drive plate from moving along the width direction of the frame.

[0022] By setting the above structure, the direction of movement of the drive board is restricted, preventing the free end of the drive board from wobbling up and down during movement, thus improving the stability of the drive board.

[0023] The beneficial effects of this invention are:

[0024] 1. By setting up an outlet, a sealing plate, and a first driving component, after the breeding pig has been tested in the testing device, the first driving component is controlled to drive the sealing plate to rotate, opening the outlet on one side of the frame. The breeding pig can then leave the testing device from the outlet without having to back out of the testing device through the opening, effectively reducing the situation where the breeding pig stays in the testing device for a long time.

[0025] 2. By setting up a push plate and a second driving component, when the outlet is opened, the second driving component is controlled to drive the push plate to move towards the outlet. The push plate drives the breeding pigs in the frame towards the outlet side, effectively preventing the breeding pigs from staying in the measuring device.

[0026] 3. By setting the lower surface of the push plate to be in contact with the upper surface of the weighing mechanism, when the push plate moves along the width direction of the frame, the push plate scrapes away feces, urine and other debris on the weighing mechanism and removes the debris from the weighing mechanism, thus avoiding debris remaining on the weighing mechanism and affecting the accuracy of the weighing mechanism.

[0027] 4. By setting up a drive board, the push plate moves and drives the drive board to move, and the drive board pushes the sealing plate to rotate and open. No additional drive structure is required, which effectively reduces operation steps and lowers costs.

[0028] 5. This invention, by incorporating a drive column, a missing gear, and a rack, allows the sealing plate to open after the drive plate has moved a short distance, facilitating the rapid exit of breeding pigs from the testing device. The sealing plate also closes after the drive plate has moved back a short distance, effectively preventing breeding pigs from entering the testing device from the exit. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1-7As shown, the present invention discloses a growth and fattening performance testing device for breeding pigs, comprising a frame 1, a weighing mechanism 21, a feeding mechanism 22, and a weighing mechanism 23. One end of the frame 1 has an opening 11. The weighing mechanism 21 is located at the bottom of the frame 1, while the feeding mechanism 22 and the weighing mechanism 23 are located at the end of the frame 1 away from the opening 11. The frame 1 is a rectangular frame 1 used to mount the weighing mechanism 21, the feeding mechanism 22, and the weighing mechanism 23. The weighing mechanism 21 automatically weighs the breeding pigs, the feeding mechanism 22 automatically fills the hopper with feed, and the weighing mechanism weighs the feed in the hopper to ensure quantitative feeding by the feeding mechanism 22. Existing technology also discloses a PLC for controlling and coordinating the operation of various components, and an identification device for identifying electronic RFID ear tags fixed to the ears of breeding pigs, identifying the pig's identity information so that the data can be uploaded to a server after the measurement is completed. The aforementioned weighing mechanism 21, feeding mechanism 22, weighing mechanism 23, PLC, and identification device are all publicly available technologies, and therefore will not be described in detail here. It is understood that an electrically controlled door can be installed at opening 11 to control the opening and closing of opening 11.

[0046] In this embodiment, an outlet 12 is provided on one side of the frame 1, and a sealing plate 3 is provided inside the outlet 12. The top of the sealing plate 3 is rotatably connected to the frame 1. Specifically, a shaft hole is provided on the top of the sealing plate 3, and a rotating shaft is fixedly provided on the frame 1 along the length direction of the frame 1. The sealing plate 3 is rotatably mounted on the rotating shaft through the shaft hole. A first driving assembly 4 is provided inside the frame 1, which is used to drive the sealing plate 3 to rotate. After the breeding pig has completed the measurement in the measuring device, the first driving assembly 4 is controlled to drive the sealing plate 3 to rotate, opening the outlet 12 on one side of the frame 1. The breeding pig can then leave the measuring device from the outlet 12 without having to back out through the opening 11, effectively reducing the situation where the breeding pig stays in the measuring device for a long time.

[0047] In this embodiment, a push plate 5 is provided on the side of the frame 1 away from the sealing plate 3, that is, the sealing plate 3 and the push plate 5 are located on opposite sides of the frame 1. The push plate 5 is slidably installed inside the frame 1 along its width direction. A second drive assembly 6 is provided inside the frame 1. The second drive assembly 6 is used to drive the push plate 5 to move along the width direction of the frame 1. When the push plate 5 moves along the width direction of the frame 1, it drives the breeding pigs inside the frame 1 toward the outlet 12. When the outlet 12 is opened, the second drive assembly 6 is controlled to drive the push plate 5 to move toward the outlet 12, thereby driving the breeding pigs inside the frame 1 toward the outlet 12 and effectively preventing the breeding pigs from remaining inside the measuring device.

[0048] In this embodiment, the lower surface of the push plate 5 is separated from the upper surface of the weighing mechanism 21. When the push plate 5 moves along the width direction of the frame 1, the push plate 5 scrapes away feces, urine and other debris on the weighing mechanism 21 and removes the debris from the weighing mechanism 21, so as to avoid the debris remaining on the weighing mechanism 21 and affecting the accuracy of the weighing mechanism 21.

[0049] In this embodiment, the first driving component 4 includes a driving plate 41, of which two driving plates 41 are provided. The end of the driving plate 41 away from the sealing plate 3 is fixedly connected to the push plate 5. Specifically, the push plate 5 has a slot, and one end of the driving plate 41 is fixedly installed in the slot. The driving plate 41 is located below the rotation axis of the sealing plate 3. When the driving plate 41 moves towards the sealing plate 3, it pushes the sealing plate 3 to rotate and open. In some other embodiments, the first driving component 4 can also be a rotary motor, which drives the sealing plate 3 to rotate through a transmission component. In this embodiment, by setting a driving plate 41 fixedly connected to the push plate 5, the push plate 5 moves, driving the driving plate 41 to move, and the driving plate 41 pushes the sealing plate 3 to rotate and open. No additional driving structure is required, effectively reducing operation steps and lowering costs.

[0050] In this embodiment, the first driving assembly 4 further includes two driving columns 42. A slot 31 is provided on the sealing plate 3 corresponding to the position of the driving plate 41. The driving columns 42 are fixedly installed in the slot 31. The axis of the driving column 42 is aligned with the rotation axis of the sealing plate 3. The height of the slot 31 is greater than the length of the driving plate 41. A missing gear 421 is fixedly provided on the outer circumference of the driving column 42, located near the push plate 5. The driving plate 41 is configured as a rack, which meshes with the missing gear 421. As the driving plate 41 moves towards the sealing plate 3, the rack on the driving plate 41 drives the missing gear 421 to rotate. The missing gear 421, through the driving column 42, drives the sealing plate 3 from a closed state to an open state, until the missing gear 421 disengages from the rack. This allows the sealing plate 3 to open after the driving plate 41 has moved a short distance, facilitating the rapid departure of the breeding pig from the testing device. It should be noted that after the sealing plate 3 is in the open state, the continuously moving drive plate 41 will keep the sealing plate 3 in the open state and cause it to oscillate slightly with the continuous movement of the drive plate 41. After the drive plate 41 stops at its maximum position, the weight of the sealing plate 3 causes the missing gear 421 to rotate towards the rack, so that the missing gear 421 re-engages with the rack. During the return movement of the sealing plate 3, the rack on the drive plate 41 drives the missing gear 421 to rotate. The missing gear 421 drives the sealing plate 3 to rotate inward from the open state to the closed state through the drive column 42, until the missing gear 421 disengages from the rack. This allows the sealing plate 3 to close after the drive plate 41 has moved back a short distance, effectively preventing the breeding pigs from entering the testing device from the outlet 12. It should also be noted that after the sealing plate 3 is in the closed state, the continuously moving drive plate 41 will keep the sealing plate 3 in the closed state and cause it to oscillate slightly with the continuous movement of the drive plate 41.

[0051] In this embodiment, the second drive assembly 6 includes a drive motor 61 and two screws 62. The frame 1 has two mounting plates 13 arranged above the push plate 5 along the width direction of the frame 1. Mounting grooves 131 are formed on the mounting plates 13 along their length direction. Two mounting ears 51 are provided on the top of the push plate 5, and the two mounting ears 51 are slidably installed in the two mounting grooves 131 respectively. The screws 62 are arranged along the length direction of the mounting plates 13, and both ends of the screws 62 are rotatably connected to the frame 1. The mounting ears 51 are threaded onto the screws 62. The drive motor 61 is fixedly connected to the frame 1, and the drive motor 61 is drive-driven to the screws 62. In this embodiment, an output gear is drive-driven onto the output shaft of the drive motor 61, and a transmission gear is fixedly connected to the screws 62. A chain is tensioned between the output gear and the two transmission gears.

[0052] In this embodiment, a side plate 7 is provided on the side of the push plate 5 away from the sealing plate 3. The side plate 7 is fixedly connected to the frame 1 and is used to close the side of the frame 1 away from the sealing plate 3. In some other embodiments, the side plate 7 may not be necessary; the push plate 5 can simply be placed against the wall on the side away from the sealing plate 3. In this embodiment, by providing the side plate 7, the side of the frame 1 away from the sealing plate 3 is closed, preventing the breeding pig from entering the measuring device from the side of the frame 1 away from the sealing plate 3 during the movement of the push plate 5 towards the sealing plate 3.

[0053] In this embodiment, a support plate 14 is provided above the drive plate 41 in the frame 1. A connecting rod 141 is fixedly installed on the lower surface of the support plate 14 near the push plate 5. A sliding groove 412 is formed on the upper surface of the drive plate 41. A limiting head 142 is provided at the free end of the connecting rod 141. The limiting head 142 is slidably locked in the sliding groove 412. The limiting head 142 is used to restrict the movement of the drive plate 41 along the width direction of the frame 1. The movement direction of the drive plate 41 is restricted to prevent the free end of the drive plate 41 from shaking up and down during the movement, thereby improving the stability of the drive plate 41.

[0054] The working principle of this invention is as follows:

[0055] After the breeding pigs entering the testing device have completed the testing,

[0056] The drive motor 61 is controlled to operate. The drive motor 61 drives the transmission gear on the screw 62 to rotate via the output gear and chain. The transmission gear then drives the screw 62 to rotate. During the rotation of the screw 62, the push plate 5 moves closer to the sealing plate 3. This movement of the push plate 5 causes the drive plate 41 to move synchronously.

[0057] As the drive plate 41 moves toward the sealing plate 3, the rack on the drive plate 41 drives the missing gear 421 to rotate. The missing gear 421 drives the sealing plate 3 to rotate outward from the closed state to the open state through the drive column 42, until the missing gear 421 disengages from the rack.

[0058] After the sealing plate 3 is in the open state, the continuously moving drive plate 41 will keep the sealing plate 3 in the open state and make it swing slightly as the drive plate 41 continues to move until the push plate 5 moves to the maximum position.

[0059] During the movement of the push plate 5, on the one hand, the push plate 5 drives the breeding pigs in the frame 1 toward the exit 12. On the other hand, the push plate 5 scrapes away feces, urine and other debris on the weighing mechanism 21 and removes the debris from the weighing mechanism 21.

[0060] When the breeding pig leaves the testing device, it is necessary to close the sealing plate 3.

[0061] The drive motor 61 is controlled to work. The drive motor 61 drives the transmission gear on the screw 62 to rotate in the opposite direction through the output gear and chain, thereby causing the push plate 5 to drive the drive plate 41 to move away from the sealing plate 3, that is, the sealing plate 3 moves back.

[0062] During the retraction of the sealing plate 3, the rack on the drive plate 41 drives the misaligned gear 421 to rotate. The misaligned gear 421, through the drive column 42, drives the sealing plate 3 to rotate inward from the open state to the closed state, until the misaligned gear 421 disengages from the rack. After the sealing plate 3 is in the closed state, the continuously moving drive plate 41 keeps the sealing plate 3 in the closed state and causes it to swing slightly with the continuous movement of the drive plate 41 until the sealing plate 3 returns to its initial position.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention. Technical aspects, shapes, and structures not described in detail in this invention are all well-known technologies.
