Description

Technical Field

[0001] The present invention relates to the technical field of breeding pigs, in particular to a device for measuring the growth and fattening performance of breeding pigs. Background Art

[0002] Starting from the end of the nursery, preliminary selection will be conducted on pigs to be tested for growth and fattening performance. The selected individuals must be healthy, without genetic defects (cryptorchidism, atresia, etc.), with normal growth and development, and body shape and appearance that conform to the breed characteristics. The standard number of pigs for fattening performance testing is to ensure that there are two boars and three sows in each litter before the end of the nursery, and one boar and two sows in each litter at the end of the test (if conditions permit, whole-group testing can be carried out). Boars are tested in single pens or with automatic breeding pig performance testing equipment, and sows are tested in small groups. During the test, they can eat and drink freely, and the test indicators include daily weight gain, feed conversion rate, and age at 75kg body weight.

[0003] In the prior art, most automatic sow performance measurement devices include a frame, a weighing mechanism, a feeding mechanism, and a weighing mechanism. For example, Chinese Patent Publication No. CN108617539B discloses a closed intelligent sow measurement station, which includes a frame, a weighing fence, a feeding device, and a weighing device. The weighing fence is connected to the frame via multiple first weighing sensors, and an antenna board and a controller are provided within the frame. The antenna board collects sow information, and the controller is connected to a host computer for communication. The first weighing sensor, the second weighing sensor, and the antenna board transmit the monitored signals to the controller, which controls the feeding device.

[0004] However, most current measurement devices only have a single opening, through which the pig enters the device and, after the measurement is complete, exits the device by backing out. In actual use, this is inconvenient for the pig to back out of the device, and can easily cause the pig to remain inside the device for extended periods, hindering subsequent pigs from entering. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a growth and fattening performance measuring device for breeding pigs, so as to solve the problem in the prior art that the breeding pigs have to exit the measuring device from the opening by backward movement, which is inconvenient and the breeding pigs are likely to stay in the measuring device for a long time, affecting the entry of subsequent breeding pigs.

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

[0007] A growth and fattening performance measuring device for breeding sows comprises a frame, a weighing mechanism, a feeding mechanism and a weighing mechanism. An opening is provided at one end of the frame, the weighing mechanism is arranged at the bottom of the frame, the feeding mechanism and the weighing mechanism are arranged at the end of the frame away from the opening, an outlet is provided on one side of the frame, a sealing plate is provided in the outlet, the top of the sealing plate is rotatably connected to the frame, a first drive assembly is provided in the frame, and the first drive assembly is used to drive the sealing plate to rotate.

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

[0009] Furthermore, a push plate is provided on the side of the frame away from the sealing plate, and the push plate is slidably installed in the frame along the width direction of the frame. A second drive assembly is provided in the frame, and the second drive assembly 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 to the exit side.

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

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

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

[0013] Furthermore, the first driving assembly includes a driving plate, the end of the driving plate away from the sealing plate is fixedly connected to the push plate, the driving plate is located below the sealing plate rotation axis, and when the driving plate moves toward the sealing plate, the driving plate pushes the sealing plate to rotate and open.

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

[0015] Furthermore, the first driving component also includes a driving column, a slot is provided on the sealing plate at a 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 in 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, and the rack is engaged with the missing gear.

[0016] By setting the above structure, when the driving plate moves toward the closing plate, the rack on the driving plate drives the missing gear to rotate, and the missing gear drives the closing plate from the closed state to the open state through the driving column until the missing gear is disengaged from the rack. The closing plate can be opened after the driving plate moves a short distance, which is convenient for the breeding pigs to quickly leave the measuring device. After the driving plate moves to the maximum position and stops, the deadweight of the closing plate causes the missing gear to rotate toward the rack, so that the missing gear is re-engaged with the rack. When the closing plate moves back, the rack on the driving plate drives the missing gear to rotate, and the missing gear drives the closing plate from the open state to the closed state through the driving column until the missing gear is disengaged from the rack. The closing plate can be closed after the driving plate moves back a short distance, which can effectively prevent the breeding pigs from entering the measuring device from the exit.

[0017] Furthermore, the second driving assembly includes a driving motor and a screw rod. The frame is provided with a mounting plate above the push plate along the width direction of the frame. A mounting groove is provided on the mounting plate along the length direction of the mounting plate. A mounting ear is provided on the top of the push plate. The mounting ear is slidably installed in the mounting groove. The screw rod is provided along the length direction of the mounting plate. Both ends of the screw rod are rotatably connected to the frame. The mounting ear is threadedly connected to the screw rod. The driving motor is fixedly connected to the frame, and the driving motor is transmission-connected to the screw rod.

[0018] By setting the above structure, the transmission connection between the second drive assembly 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 the side plate is used to close the side of the frame away from the sealing plate.

[0020] By setting 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 movement of the push plate toward the sealing plate.

[0021] Furthermore, the frame is provided with a support plate above the driving plate, a connecting rod is fixedly installed on the lower surface of the support plate near one end of the push plate, a sliding groove is provided on the upper surface of the driving plate, and a limiting head is provided at the free end of the connecting rod, and the limiting head is slidably clamped in the sliding groove, and the limiting head is used to limit the movement of the driving plate along the width direction of the frame.

[0022] By providing the above structure, the moving direction of the driving plate is restricted, preventing the free end of the driving plate from shaking up and down during the movement, thereby improving the driving stability of the driving plate.

[0023] Beneficial effects of the present invention:

[0024] 1. The present invention provides an outlet, a sealing plate and a first driving assembly. When the measurement of the breeding pig is completed in the measuring device, the first driving assembly is controlled to drive the sealing plate to rotate, and the outlet on one side of the frame is opened. The breeding pig can leave the measuring device from the outlet without having to exit the measuring device from the opening by backing up, which effectively reduces the situation where the breeding pig stays in the measuring device for a long time.

[0026] 3. The present invention sets the lower surface of the push plate and the upper surface of the weighing mechanism to be in contact with each other. When the push plate moves along the width direction of the frame, the push plate scrapes away debris such as feces and urine on the weighing mechanism and scrapes the debris away from the weighing mechanism, thereby preventing the debris from remaining on the weighing mechanism and affecting the accuracy of the weighing mechanism.

[0027] 4. The present invention sets a driving plate. When the push plate moves, the driving plate drives the driving plate to move. The driving plate pushes the sealing plate to rotate and open. There is no need to set up an additional driving structure, which effectively reduces the operation steps and reduces costs.

[0028] 5. By providing a drive column, a gear, and a rack, the present invention allows the sealing plate to open after the drive plate moves a short distance, facilitating the rapid exit of the measuring device by the breeding pig. The sealing plate can also close after the drive plate moves back a short distance, effectively preventing the breeding pig from entering the measuring device through the exit.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figure 1-Figure 7As shown, the growth and fattening performance measuring device for breeding boars of the present application comprises a frame 1, a weighing mechanism 21, a feeding mechanism 22, a weighing mechanism 23, an opening 11 is formed at one end of the frame 1, the weighing mechanism 21 is arranged at the bottom of the frame 1, and the feeding mechanism 22 and the weighing mechanism 23 are arranged at the end of the frame 1 away from the opening 11. Among them, the frame 1 is a rectangular frame 1, which is used to install the weighing mechanism 21, the feeding mechanism 22 and the weighing mechanism 23. The weighing mechanism 21 is used to automatically weigh the weight of the boar, the feeding mechanism 22 is used to automatically fill the feed into the hopper, and the weighing mechanism is used to weigh the weight of the feed in the hopper, so that the feeding mechanism 22 can quantitatively feed. The prior art also discloses a PLC for controlling and coordinating the work of each component, and an identification device for identifying the electronic RFID ear tag fixed on the ear of the boar to identify the identity information of the boar, so that the data can be uploaded to the server after the measurement is completed. The prior art of the above weighing mechanism 21, feeding mechanism 22, weighing mechanism 23, PLC and identification device has been fully disclosed, so it will not be described in more detail. It can be understood that the opening 11 can be provided with an electric control door to control the on-off of the opening 11.

[0046] In this embodiment, an outlet 12 is formed at one side of the frame 1, and a sealing plate 3 is arranged in the outlet 12. The top of the sealing plate 3 is rotatably connected with the frame 1. Specifically, an axle hole is formed in the top of the sealing plate 3, and a rotating shaft is fixedly arranged on the frame 1 along the length direction of the frame 1. The sealing plate 3 is rotatably installed on the rotating shaft through the axle hole. A first driving assembly 4 is arranged in the frame 1, and the first driving assembly 4 is used to drive the sealing plate 3 to rotate. When the boar completes the measurement in the measuring device, the first driving assembly 4 is controlled to drive the sealing plate 3 to rotate, so that the outlet 12 at one side of the frame 1 is opened, and the boar can leave the measuring device from the outlet 12, without the need to exit the measuring device from the opening 11 in a backward manner, thereby effectively reducing the situation that the boar stays in the measuring device for a long time.

[0047] In this embodiment, a push plate 5 is arranged at the side of the frame 1 away from the sealing plate 3, that is, the sealing plate 3 and the push plate 5 are respectively located at two sides of the frame 1. The push plate 5 is slidably installed in the frame 1 along the width direction of the frame 1. A second driving assembly 6 is arranged in the frame 1, and the second driving 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, the push plate 5 drives the boar in the frame 1 to the outlet 12 side. When the outlet 12 is opened, the second driving assembly 6 is controlled to drive the push plate 5 to move towards the outlet 12, so that the boar in the frame 1 is driven to the outlet 12 side by the push plate 5, thereby effectively avoiding the situation that the boar stays in the measuring device.

[0048] In the embodiment, the lower surface of the push plate 5 is in contact with 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 sweeps the excrement, urine and other sundries on the weighing mechanism 21, and scrapes the sundries off the weighing mechanism 21, so as to avoid the sundries remaining on the weighing mechanism 21, and affecting the accuracy of the weighing mechanism 21.

[0049] In the embodiment, the first driving assembly 4 comprises two driving plates 41, one end of the driving plate 41 away from the sealing plate 3 is fixedly connected with the push plate 5, specifically, a notch is formed on the push plate 5, and one end of the driving plate 41 is fixedly installed in the notch. The driving plate 41 is located below the rotation shaft of the sealing plate 3, when the driving plate 41 moves towards the sealing plate 3, the driving plate 41 pushes the sealing plate 3 to rotate and open. In other embodiments, the first driving assembly 4 can also be a rotary motor, which can drive the sealing plate 3 to rotate through a transmission member. In the embodiment, the driving plate 41 is fixedly connected with the push plate 5, when the push plate 5 moves, the driving plate 41 moves, and the driving plate 41 pushes the sealing plate 3 to rotate and open, without the need for additional driving structure, effectively reducing the operation steps and reducing the cost.

[0050] In this embodiment, the first drive assembly 4 also includes a drive column 42, and there are two drive columns 42. A notch 31 is provided on the sealing plate 3 at a position corresponding to the drive plate 41. The drive column 42 is fixedly installed in the notch 31. The axis of the drive column 42 is in the same straight line as the rotation axis of the sealing plate 3. The height of the notch 31 is greater than the length of the drive plate 41. A missing gear 421 is fixedly provided on the outer circumference of the drive column 42. The missing gear 421 is located on the side close to the push plate 5. The drive plate 41 is configured as a rack, and the rack is engaged with the missing gear 421. In the process of the drive plate 41 moving 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 is disengaged from the rack. This allows the sealing plate 3 to open after the drive plate 41 moves a short distance, making it convenient for the breeding pig to quickly leave the measuring device. It should be noted that after the closing plate 3 is in the open state, the continuously moving drive plate 41 will keep the closing plate 3 in the open state, and produce a small swing with the continuous movement of the drive plate 41. After the drive plate 41 moves to the maximum position and stops, the deadweight of the closing plate 3 causes the missing gear 421 to rotate in the direction close to the rack, so that the missing gear 421 re-engages with the rack. In the process of the closing plate 3 moving back, the rack on the drive plate 41 drives the missing gear 421 to rotate, and the missing gear 421 drives the closing 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, so that the closing plate 3 can be closed after the drive plate 41 moves back a short distance, which can effectively prevent the breeding pigs from entering the measuring device from the exit 12. It should be noted that after the closing plate 3 is in the closed state, the continuously moving drive plate 41 will keep the closing plate 3 in the closed state, and produce a small swing 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. Two mounting plates 13 are provided on the frame 1 above the push plate 5 along the width of the frame 1. Mounting slots 131 are defined on the mounting plates 13 along their length. Two mounting ears 51 are provided on the top of the push plate 5. The two mounting ears 51 are slidably mounted within the two mounting slots 131. The screws 62 are provided along the length of the mounting plates 13. Both ends of the screws 62 are rotationally connected to the frame 1. The mounting ears 51 are threadedly connected to the screws 62. The drive motor 61 is fixedly connected to the frame 1 and is in transmission connection with the screws 62. In this embodiment, an output gear is transmission-connected to the output shaft of the drive motor 61. A transmission gear is fixedly connected to the screw 62. A chain is tensioned between the output gear and the two transmission gears.

[0052] In this embodiment, a side panel 7 is provided on the side of the push plate 5 facing away from the sealing plate 3. The side panel 7 is fixedly connected to the frame 1 and serves to seal the side of the frame 1 facing away from the sealing plate 3. In other embodiments, the side panel 7 may not be required, and the side of the push plate 5 facing away from the sealing plate 3 may simply be placed against a wall. In this embodiment, the side panel 7 seals the side of the frame 1 facing away from the sealing plate 3, preventing the pig from entering the measurement device from the side of the frame 1 facing away from the sealing plate 3 while the push plate 5 moves toward the sealing plate 3.

[0053] In this embodiment, the frame 1 is provided with a support plate 14 above the drive plate 41. A connecting rod 141 is fixedly mounted on the lower surface of the support plate 14 at one end near the push plate 5. A sliding groove 412 is provided 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 slides and engages in the sliding groove 412. The limiting head 142 is used to limit 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 movement, thereby improving the driving stability of the drive plate 41.

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

[0055] After the sows have entered the measuring device and have completed the measurement,

[0056] The drive motor 61 is controlled to operate, and the drive motor 61 drives the transmission gear on the screw 62 to rotate through the output gear and chain, and the transmission gear drives the screw 62 to rotate. As the screw 62 rotates, the push plate 5 moves toward the closing plate 3. As the push plate 5 moves, the drive plate 41 moves synchronously.

[0057] As the drive plate 41 moves toward the closing plate 3, the rack on the drive plate 41 drives the missing gear 421 to rotate, and the missing gear 421 drives the closing 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 closing plate 3 is in the open state, the continuously moving driving plate 41 will keep the closing plate 3 in the open state, and generate a small swing with the continuous movement of the driving plate 41 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 sows in the frame 1 toward the outlet 12. On the other hand, the push plate 5 scrapes away debris such as feces and urine on the weighing mechanism 21 and scrapes the debris away from the weighing mechanism 21.

[0060] When the sow leaves the measuring device and needs to close the sealing plate 3,

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

[0062] 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 from the open state to the closed state through the drive column 42, until the missing gear 421 disengages from the rack. After the sealing plate 3 is in the closed state, the continued movement of the drive plate 41 will keep the sealing plate 3 in the closed state, and it will swing slightly with the continued movement of the drive plate 41 until the sealing plate 3 returns to its original position.

[0063] The above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that the technical solutions of the present invention may be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention, and such modifications or equivalents shall be encompassed by the claims of the present invention. Any techniques, shapes, and structures not described in detail herein are well known.
