Description

Technical Field

[0001] This invention relates to the field of broiler breeder management technology, and more particularly to a cage-raising device for layer chickens used for selection and performance testing. Background Technology

[0002] Currently, stacked egg-laying hen cages are commonly used in egg-laying hen farming. These cages require little floor space, have high space utilization, and are easily adapted for intensive and large-scale farming. Furthermore, existing stacked egg-laying hen cages are equipped with automatic egg collection and conveying systems. After laying eggs, they roll onto an egg tray on one side of the cage, and are then transported by a conveyor belt to an automatic egg collection device. This device automatically collects the eggs, significantly reducing manual labor and improving collection efficiency.

[0003] However, in egg-laying hen farming, regular selection and performance testing of hens are necessary to obtain the highest quality eggs. These processes require individual cage rearing and data collection. Current cages typically house multiple hens in the same space, resulting in large internal compartments. Placing only one hen in each cage leads to wasted space. Even disregarding this space waste, eggs from each hen will inevitably roll onto the egg tray, causing mixing. Furthermore, automated egg collection and conveying systems cannot be applied in this situation. Summary of the Invention

[0004] The main objective of this invention is to provide a cage-raising device for laying hens for selection and performance testing. By improving the internal structure of the cage, multiple compartments are added to the cage, and the size of the compartments can be adjusted according to actual conditions. In addition, an egg-blocking mechanism and a coding mechanism are added. The egg-blocking mechanism can separate eggs laid by different laying hens during the egg collection process, and then the eggs are automatically marked by the coding mechanism before being transported and collected in a unified manner, which facilitates subsequent selection, performance testing, etc.

[0005] To solve the above-mentioned technical problems, the present invention is implemented as follows: a cage-raising device for laying hens for selection and performance testing, comprising: a cage body, an egg collection tray, an egg-blocking mechanism, and a coding mechanism;

[0006] The cage is a long rectangular structure with a sloping bottom. Multiple compartments are arranged sequentially along the length of the cage. An opening is provided at the bottom of the front of the cage, which is connected to each compartment inside the cage.

[0007] The egg collection tray is set at the bottom of the front of the cage along the length of the cage body. One side of the egg collection tray along the length of the cage body is connected to the bottom of the opening, and the other side is provided with a stop plate.

[0008] The egg-blocking mechanism is located above the egg collection tray. The mechanism includes a control unit, a rotating plate, and multiple egg-blocking rods.

The control unit can control all egg-blocking rods to rotate simultaneously and move away from the egg collection tray.

[0009] The coding mechanism is located above the egg-blocking bar. The coding mechanism includes an automatic coding device, a cylinder, and a power unit that drives the cylinder to move along the length of the egg collection tray. The cylinder is mounted on the power unit, and the automatic coding device is fixedly mounted on the end of the piston rod of the cylinder. The automatic coding device is equipped with an image recognition sensor.

[0010] As a further technical solution, the egg collection tray has a recessed part in the center, the recessed part is arranged along the length direction of the egg collection tray, and the automatic inkjet printer is located directly above the recessed part.

[0011] As a further technical solution, a feeding trough is provided on the front of the cage, the feeding trough is arranged along the length direction of the cage, and the feeding trough extends from one end of the length direction of the cage to the other end; a fixing plate is fixedly provided at both ends of the feeding trough.

[0012] As a further technical solution, the control unit includes a rotating rod, a lifting rope, and a first stepper motor. The rotating rod is arranged along the length of the cage body, and its two ends are fixed to both sides of the cage body. A rotating wheel is fixed to each end of the rotating rod. There are two lifting ropes, which are symmetrically arranged at both ends of the rotating rod. One end of the lifting rope is connected to the egg-blocking bar at the corresponding first or last end, and the other end passes through the corresponding fixing plate and is wound around the corresponding rotating wheel. The lifting rope is connected to the end of the egg-blocking bar away from the stop plate. The first stepper motor is located at one end of the rotating rod, and its motor shaft is fixedly connected to the corresponding end of the rotating rod.

[0013] As a further technical solution, the egg-stopping rod includes an upper straight rod, an inclined rod, and a lower straight rod. The upper and lower straight rods are staggered vertically and arranged in parallel. The inclined rod is inclined between the upper and lower straight rods, and its two ends are respectively connected to the ends of the upper and lower straight rods. The end of the upper straight rod away from the inclined rod is provided with a U-shaped clamp, and the egg-stopping rod is clamped onto the rotating plate through the clamp.

[0014] As a further technical solution, the power unit includes a mounting base and a slider. The mounting base is installed between the fixed plates at both ends of the feeding trough along the length of the cage. The bottom of the mounting base is provided with a ball screw and a slide rail. The slide rail and the ball screw are arranged adjacent to each other and both are arranged along the length of the mounting base. The slide rail is fixedly installed at the bottom of the mounting base, and the ball screw is rotatably installed at the bottom of the mounting base. One end of the ball screw is provided with a second stepper motor that drives its rotation. The slider is located below the mounting base. The slider is provided with a groove-shaped structure that slides with the slide rail and a connecting hole that corresponds to the ball screw. The bottom of the slider is fixedly connected to a cylinder.

[0015] As a further technical solution, the cage body is a mesh structure; the back of the cage body has an opening, and a baffle that can be opened and closed is provided at the opening; the bottom of the baffle is rotatably connected to the bottom of the opening by a hinge, and the top two ends of the baffle are respectively provided with fixing holes; corresponding snap-fit ​​seats are provided on the side walls of the left and right sides of the cage body, and an L-shaped rotating rod is slidably provided in the snap-fit ​​seat, with one end of the L-shaped rotating rod passing through the snap-fit ​​seat and into the corresponding fixing hole.

[0016] As a further technical solution, the cage body has multiple partitions arranged at intervals along its length, which divide the cage body into multiple compartments. The top wall inside the cage body has multiple sliding grooves arranged at intervals along its length. The partitions are inserted into the corresponding sliding grooves and are slidably connected to the sliding grooves. The bottom of the partitions is set as an inclined side that matches the bottom of the cage body. The baffle has multiple openable cage doors, each cage door being set between two adjacent sliding grooves.

[0017] As a further technical solution, a transition plate is inclined on the side of the egg collection tray away from the stop plate. The transition plate is integrally formed with the egg collection tray. The side of the transition plate away from the egg collection tray is fixedly connected to the bottom of the opening on the front of the cage. A detachable guide frame is installed at the bottom of the side of each partition near the opening. The guide frame is trapezoidal.

[0018] As a further technical solution, the end of the flow guide frame connected to the partition plate is provided with a rectangular opening, and a snap-fit ​​mechanism is provided at the opening. The flow guide frame is snapped onto the partition plate by the snap-fit ​​mechanism. There are two sets of snap-fit ​​mechanisms, which are symmetrically arranged on both sides of the opening. Each set of snap-fit ​​mechanisms includes a spring and a cap. The spring is fixedly installed on the side wall of the opening, and the cap covers the outside of the spring and is fixedly connected to the spring.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This application uses partitions to divide the cage into multiple compartments, allowing each laying hen to be placed in a separate compartment, thus achieving independent zoning for each hen and facilitating breeding or performance testing. The top wall of the cage has grooves for installing the partitions, and the back of the cage has a baffle that can be opened, facilitating the installation or adjustment of the partition positions and consequently the size of the compartments, thereby improving the utilization rate of the area. Alternatively, depending on the actual situation, a partition can be inserted every other groove or every two grooves to expand the space of each compartment. Or, all partitions or some partitions can be removed, turning the cage into a regular chicken cage, achieving multiple uses from one cage.

[0021] 2. This application further includes an egg-blocking mechanism and a coding mechanism on the egg collection tray. Egg-blocking bars separate eggs laid by hens in adjacent compartments, preventing mixing between eggs from different hens and facilitating subsequent selection and performance testing. After being marked and distinguished by an automatic coding mechanism, the eggs are then transported uniformly by a conveyor belt. The egg-blocking and coding mechanisms significantly reduce the intensity of manual egg collection and improve collection efficiency. Furthermore, these mechanisms allow existing automatic egg collection and conveying systems to be applied to this cage as well. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] like Figures 1-8 As shown, the present invention proposes a cage-raising device for laying hens for selection and performance testing, comprising: a cage body 1, an egg collection tray 2, an egg blocking mechanism 3, and a coding mechanism 4.

[0039] like Figure 1 and Figure 4 As shown, cage 1 is a long, rectangular structure with a mesh structure. The bottom of cage 1 is a sloped surface (the slope is small and not easily shown in the figure). An opening 10 is provided at the bottom of the front of cage 1, extending along the length of cage 1 and communicating with the interior of cage 1. Figure 6 , Figure 7As shown, the back of the cage 1 has an opening, meaning the back of the cage 1 is an open structure. A baffle 12, which can be opened and closed, is provided at the opening. The baffle 12 can be a mesh structure. The bottom of the baffle 12 is rotatably connected to the bottom of the opening via a hinge. Two symmetrical fixing seats 13 are provided at both ends of the top of the baffle 12 along its length. Each fixing seat 13 has a fixing hole 130, the axis of which is parallel to the length of the baffle 12. A corresponding snap-fit ​​seat 15 is provided on the sidewalls of both the left and right sides of the cage 1. The snap-fit ​​seat 15 is located on the side of the corresponding sidewall closest to the baffle 12. An L-shaped rotating rod 14 slides within the snap-fit ​​seat 15. One end of the L-shaped rotating rod 14 passes through the snap-fit ​​seat 15 and into the corresponding fixing hole 130, thereby fixing the baffle 12 to the opening.

[0040] like Figure 2 and 6 As shown, the cage 1 has multiple compartments arranged sequentially along its length, and the opening 10 on the front of the cage 1 is interconnected with each compartment. Multiple partitions 16 are arranged at intervals along the length of the cage 1, dividing the cage 1 into multiple compartments. Multiple sliding grooves 17 are arranged at intervals along the length of the top wall inside the cage 1, with each partition 16 inserted into and slidably connected to the corresponding sliding groove 17; the bottom of the partition 16 is a beveled edge that mates with the bottom of the cage 1. The partitions 16 may also be of a mesh structure.

[0041] Other examples Figure 7 As shown in the figure, the baffle 12 is provided with a plurality of openable cage doors 18. Each cage door 18 is provided between two adjacent slides 17, that is, each cage door 18 corresponds to a compartment, thereby realizing the independence of each compartment, and the laying hen can be put into or taken out from the corresponding compartment.

[0042] In this application, the baffle 12 on the back of the cage 1 can be opened, and the specific operation is as follows: Figure 6As shown, the L-shaped rotating rods 14 at both ends of the baffle 12 are pulled out of the fixing holes 130, so that the baffle 12 is no longer restricted by the L-shaped rotating rods 14, and then the baffle 12 can be opened. After the baffle 12 is opened, the opening can expose the entire interior of the cage 1. At this time, the position of the partitions 16 can be installed or adjusted, and a partition 16 is inserted into each slide 17. The space between two adjacent partitions 16 forms a compartment, and one laying hen is placed in each compartment, thus realizing independent partitioning for each laying hen, which is convenient for breeding or performance testing. The distance between two adjacent slides 17 is set according to the maximum volume of the laying hens in the actual situation, so that the space of each compartment is sufficient and avoids the space being too small. Alternatively, depending on the actual situation, a partition 16 can be inserted every other slide 17 or every two slides 17, thereby expanding the space of each compartment. If breeding or performance testing is not required, there is no need for too many separate compartments. All partitions 16 or some partitions 16 can be removed, thus turning this cage 1 into a regular chicken cage. In addition, after adjusting the partition 16 and closing the baffle 12, the cage door 18 corresponding to each compartment can be opened to put the laying hen into or take it out of the compartment. The cage door 18 ensures the independence of each compartment and facilitates the removal of any laying hen for observation during the test.

[0043] like Figure 1 and Figure 2 As shown, a feeding trough 5 is provided on the front of the cage body 1. The feeding trough 5 is arranged along the length direction of the cage body 1 and extends from one end of the length direction of the cage body 1 to the other end. The two ends of the feeding trough 5 are respectively symmetrically provided with fixing plates 50.

[0044] like Figures 1-4 As shown, the egg collection tray 2 is positioned along the length of the cage body 1 at the bottom of the front side of the cage body 1. One side of the egg collection tray 2 along its length is aligned with the bottom of the opening 10, and the other side is equipped with a stop plate 20. After the hen lays an egg, the egg can roll down the slope onto the egg collection tray 2, and the stop plate 20 acts as a stop to prevent the egg from falling out of the egg collection tray 2. Specifically, as shown... Figure 3 and Figure 4As shown, the egg collection tray 2 has a recessed portion 21 in the center, which is located along the length of the tray. This recessed portion 21 is the lowest point on the tray, so when an egg rolls from the compartment onto the tray, it will eventually settle in this recessed portion. A transition plate 22 is inclined on the side of the egg collection tray 2 away from the stop plate 20. The transition plate 22 is integrally formed with the tray, and its side away from the tray is fixedly connected to the bottom of the opening 10 on the front of the cage 1. End plates 220 are fixedly attached to both ends of the transition plate 22 along its length. After the hen lays an egg, the egg rolls down the inclined surface onto the transition plate 22, and then from there onto the tray. The slope of the transition plate 22 is less than that of the bottom slope of the cage 1. The transition plate 22 can gradually slow down the rolling speed of the eggs, so as to prevent the eggs from being damaged by collision with the stop plate 20 due to excessive speed, or from being ejected from the egg collection tray 2 after colliding with the stop plate 20.

[0045] In addition, each partition 16 has a removable guide frame 23 installed at its bottom on the side near the opening 10. The guide frame 23 is trapezoidal, such as... Figure 4 and Figure 5 As shown, the smaller end of the flow guide frame 23 is secured to the partition 16, while the larger end is located near the egg collection tray 2. The end of the flow guide frame 23 connected to the partition 16 has a rectangular opening 230; that is, the smaller end of the flow guide frame 23 has an opening 230. A locking mechanism is provided at the opening 230, and the flow guide frame 23 is secured to the partition 16 via this mechanism. Figure 5 As shown, there are two sets of snap-fit ​​mechanisms, which are symmetrically arranged on both sides of the opening 230. Each set of snap-fit ​​mechanisms includes a spring 24 and a cap 25. The spring 24 is fixedly installed on the side wall of the opening 230, and the cap 25 covers the outside of the spring 24 and is fixedly connected to the spring 24.

[0046] The guide frame 23 in this application primarily serves a guiding function. Adjacent guide frames 23 form a channel for eggs to pass through, ensuring that when eggs from each compartment roll down the transition plate 22 onto the egg tray 2, they pass through the corresponding channel within that compartment, preventing them from rolling into other channels and ensuring a one-to-one correspondence between eggs and hens. Simultaneously, the guide frame 23 is trapezoidal, making the channel narrower closer to the egg tray 2, thus ensuring that the eggs ultimately land on the egg tray 2 near the center of that compartment. Furthermore, the snap-fit ​​mechanism allows the guide frame 23 to be easily detached, making the guide frame 23 and the partition 16 independent and facilitating adjustment of the partition 16's position.

[0047] like Figures 1-3As shown, the egg-blocking mechanism 3 is located above the egg collection tray 2. The egg-blocking mechanism 3 includes a control unit 30, a rotating plate 31, and multiple egg-blocking rods 32. The rotating plate 31 is positioned along the length of the egg collection tray 2 on the stop plate 20, and the bottom of the rotating plate 31 is rotatably connected to the stop plate 20. The egg-blocking rods 32 are located on the surface of the egg collection tray 2, and multiple egg-blocking rods 32 are arranged sequentially along the length of the cage body 1. Each egg-blocking rod 32 is positioned between two adjacent compartments, and one end of each egg-blocking rod 32 is engaged with the top of the rotating plate 31. The egg-blocking rods 32 are used to separate the eggs in adjacent compartments. The control unit 30 can control all egg-blocking rods 32 to rotate simultaneously and move away from the egg collection tray 2. Specifically, the control unit 30 includes a rotating rod 300, a lifting rope 301, and a first stepper motor 303. The rotating rod 300 is positioned along the length of the cage body 1, and both ends of the rotating rod 300 are fixed to the sides of the cage body 1. Figure 3 As shown, connecting plates 3000 are fixed at both ends of the rotating rod 300, with the connecting plates 3000 on both sides fixed to the left and right sides of the cage body 1, respectively. Additionally, rotating wheels 302 are fixed at both ends of the rotating rod 300. Two lifting ropes 301 are provided, symmetrically arranged at both ends of the rotating rod 300. One end of each lifting rope 301 is connected to the corresponding egg-blocking bar 32 at the beginning or end, and the other end passes through the corresponding fixing plate 50 and is wound around the corresponding rotating wheel 302. The lifting rope 301 is connected to the end of the egg-blocking bar 32 furthest from the stop plate 20. Figure 3 As shown, the lower side of the fixing plate 50 has a through hole. The lifting rope 301 passes through the through hole and extends to the rotating wheel 302, where it is wound around the wheel 302. The first stepper motor 303 is located at one end of the rotating rod 300, and its motor shaft is fixedly connected to the corresponding end of the rotating rod 300. A motor mount (not shown in the figure) for fixing the first stepper motor 303 can be provided below the first stepper motor 303.

[0048] In this application, the egg-stop bar 32 can be configured as follows: Figure 3 The configuration shown includes an upper straight rod 320, a diagonal rod 321, and a lower straight rod 322. The upper and lower straight rods 320 and 322 are staggered vertically and parallel to each other. The diagonal rod 321 is inclined between the upper and lower straight rods 320 and 322, with one end fixedly connected to the end of the upper straight rod 320 and the other end fixedly connected to the end of the lower straight rod 322. The upper straight rod 320 has a U-shaped locking head 323 at the end away from the diagonal rod 321. This locking head 323 is made of a flexible metal sheet, and the egg-stopping rod 32 can be secured to the rotating plate 31 through this locking head 323. The lower straight rod 322 has a through hole at a position away from the diagonal rod 321, allowing the lifting rope 301 to pass through and be fixed there. Figure 3As shown, this is the initial state of the egg-blocking rod 32, where the lower straight rod 322 rests on the egg-collecting tray 2, and the intersection of the lower straight rod 322 and the inclined rod 321 is located at the recessed part 21 of the egg-collecting tray 2. This forms a barrier to prevent eggs from mixing in different compartments. When the barrier is not needed, the first stepper motor 303 drives the rotating rod 300 to rotate, which in turn drives the rotating wheel 302 to rotate. The rotating wheel 302 winds and tightens the lifting rope 301, thereby pulling the lower straight rod 322 of the egg-blocking rods 32 at both ends to rotate upwards, causing the egg-blocking rods 32 at both ends to rotate as a whole. This rotation is then transmitted through the rotating plate 31 to all the egg-blocking rods 32, causing them to move away from the egg-collecting tray 2. Figure 8 As shown.

[0049] like Figures 1-3 As shown, the coding mechanism 4 is located above the egg-blocking rod 32. The coding mechanism 4 includes an automatic coding device 41, a cylinder 42, and a power unit 40 that drives the cylinder 42 to move along the length of the egg collection tray 2. The cylinder 42 is mounted on the power unit 40, and the automatic coding device 41 is fixedly mounted on the piston rod end of the cylinder 42. The automatic coding device 41 is equipped with an image recognition sensor (not shown in the figure), and the automatic coding device 41 is located directly above the recess 21. The power unit 40 includes a mounting base 400 and a slider 401. The mounting base 400 is installed between the fixing plates 50 at both ends of the feeding trough 5 along the length direction of the cage body 1. The bottom of the mounting base 400 is provided with a ball screw 402 and a slide rail 403. The slide rail 403 and the ball screw 402 are arranged adjacent to each other and both are arranged along the length direction of the mounting base 400. The slide rail 403 is fixedly installed at the bottom of the mounting base 400, and the ball screw 402 is rotatably installed at the bottom of the mounting base 400. One end of the ball screw 402 is provided with a second stepper motor 404 that drives it to rotate. Vertical plates 4000 are respectively provided at both ends of the bottom of the mounting base 400. The two ends of the ball screw 402 are rotatably connected to the vertical plates 4000 respectively, and one end of the ball screw 402 passes through the vertical plate 4000 and is fixedly connected to the motor shaft of the second stepper motor 404. The second stepper motor 404 can be fixed on the corresponding vertical plate 4000. The slider 401 is located below the mounting base 400. The slider 401 has a groove-shaped structure that slides into the slide rail 403, and a corresponding connecting hole that mates with the ball screw 402. One side of the slider 401 engages with the slide rail 403 via the groove-shaped structure, while the other side is fixedly connected to the nut of the ball screw 402 via the connecting hole. The bottom of the slider 401 is fixedly connected to the cylinder 42.

[0050] This application includes a controller, in which the cylinder 42, image recognition sensor, second stepper motor 404, and first stepper motor 303 are all electrically connected to the controller. In this application, after each hen in a compartment lays an egg, the egg rolls into the recess 21 of the egg tray 2. The egg-blocking rod 32 separates the eggs from different compartments. After a certain period, the marking mechanism 4 automatically marks the eggs with inkjet printing. The second stepper motor 404 drives the ball screw 402 to rotate, causing the slider 401 to slide and move the cylinder 42 and the automatic inkjet printer 41. The automatic inkjet printer 41 is equipped with an image recognition sensor. When the image recognition sensor recognizes an egg, it transmits a signal to the controller. The controller then controls the piston rod of the cylinder 42 to extend, causing the automatic inkjet printer 41 to move downwards and mark the egg surface. To ensure that each egg's marking corresponds to its respective hen, as shown in the diagram... Figure 2 As shown, the stroke of slider 401 is almost equal to the length of cage 1, and the width of each compartment corresponds to a small segment of the overall stroke of slider 401. Therefore, it can be set in the controller that when slider 401 slides within the stroke distance corresponding to the first compartment, the automatic inkjet printer 41 prints "1", when slider 401 slides within the stroke distance corresponding to the second compartment, the automatic inkjet printer 41 prints "2", and so on. The laying hens are also pre-marked with the corresponding "1, 2...", thereby realizing the inkjet marking of eggs laid by laying hens in different compartments. The above inkjet marking is only an example, and other inkjet markings that are easy to distinguish can also be set. Due to the setting of recess 21 and guide frame 23, the eggs in each compartment will be located in recess 21, and almost all of them will be located at the center position between the two corresponding egg-blocking bars 32, which also facilitates the identification of inkjet printing mechanism 4.

[0051] It is worth noting that in this application, a conveyor belt 6, as in the prior art, can be pre-laid on the egg collection tray 2, and an automatic egg collection device, as in the prior art, can be installed at one end of the cage body 1. After the coding mechanism 4 completes the coding, the egg-blocking bar 32 is raised, and the conveyor belt 6 transports the eggs uniformly to the automatic egg collection device for unified collection. This can save a lot of manpower and improve the efficiency of egg collection. Furthermore, this application can be used as a single unit, i.e., as... Figure 1 As shown, multiple cages can also be used, for example, multiple cages 1 of this application can be stacked together to form a multi-layer cage structure; each layer of cage 1 has its own feeding trough 5, egg collection tray 2, conveyor belt 6, inkjet printing mechanism 4, egg blocking mechanism 3, etc., and each layer of cage 1 works independently.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.
