Description

Technical Field

[0001] This invention relates to the field of Silkie chicken breeding technology, specifically to a device for recording and calculating the egg production of hens used in Silkie chicken breeding. Background Technology

[0002] Silkie chickens, also known as Taihe black-boned chickens, are a specialty of Taihe County, Jiangxi Province. Currently, when breeding Silkie chickens, it's necessary to count the egg production of the hens. However, chicken coops are usually located inside the chicken house, requiring workers to reach into the coop to retrieve the eggs. Because the coops are inside the coop and some distance from the outside environment, the eggs are prone to slipping, falling, or other accidents during retrieval, resulting in egg damage and affecting subsequent breeding work.

[0003] Furthermore, when staff remove the eggs from the nests of Silkie chickens, they need to manually count the number of eggs laid. This manual counting method not only increases the labor intensity and time required for counting, but also makes it difficult for staff to concentrate if unexpected situations occur, leading to inaccuracies in the egg count and requiring them to start counting again. This affects the efficiency of the statistics and causes staff to perform repetitive work.

[0004] Therefore, in view of this, the present invention proposes a device for recording and calculating the egg production of hens used for the breeding of Silkie chickens to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a device for recording and calculating the egg production of Silkie chicken breeding hens, thereby resolving the corresponding technical issues raised in the background section.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a statistical recording device for egg production of silky black-boned chickens, comprising a chicken house body, wherein a chicken nest is fixed inside the chicken house body, and an egg-boosting component is connected inside the chicken house body.

[0007] The egg-boosting assembly includes a drive shaft rotatably connected to the rear inner wall of the chicken coop body. A turntable is fixedly connected to the outer ring surface of the front end of the drive shaft. A connecting column is fixedly connected to the front off-axis of the turntable. A fixing plate is fixedly connected to the inner top wall of the chicken coop body. A linkage shaft is rotatably connected between the fixing plate and the rear inner wall of the chicken coop body. A linkage frame and a connecting frame are sequentially fixedly connected to the outer ring surface of the linkage shaft. A connecting groove is provided on the connecting frame. The connecting column is movably connected to the connecting groove. A push plate is fixedly connected to the end of the linkage frame away from the linkage shaft. A drive motor is connected to the end of the drive shaft away from the turntable through the chicken coop body. A switch is provided on the front inner bottom wall of the chicken coop body, and the switch is electrically connected to the drive motor. Sliding rods are symmetrically fixedly connected to the front inner bottom wall of the chicken coop body. A pressing plate is slidably connected between the sliding rods, and the pressing plate is located above the switch.

[0008] Furthermore, a first spring is fixedly connected between the pressing plate and the inner bottom wall of the chicken house body, and the first spring is sleeved on the outside of the sliding rod.

[0009] Furthermore, a positioning block is fixedly connected to one inner wall of the chicken house body, and magnetic blocks are fixedly connected to the opposing surfaces of the positioning block and the push plate.

[0010] Furthermore, one end of the chicken coop is provided with through holes at equal intervals, and one end of the bottom of the chicken coop is provided with a connecting groove, which is connected to the through holes.

[0011] Furthermore, a transfer frame is fixedly connected to the inside of the connecting groove at an incline, and a fixed frame is fixedly connected to the bottom front end of the transfer frame, with an egg quantity counting component connected to the fixed frame.

[0012] Furthermore, the egg counting component includes a collection rack, with sliding plates symmetrically fixedly connected to both sides of the collection rack, and the collection rack is slidably connected to the fixed frame via the sliding plates. A pull ring is fixedly connected to the front side of the collection rack via a pull rod.

[0013] Furthermore, the collection rack has egg slots equidistantly spaced, a second spring is fixedly connected to the inner bottom wall of the egg slot, a tray is fixedly connected to the other end of the second spring, an extension plate is fixedly connected to the tray, a support plate is fixedly connected to the bottom of the extension plate by a support rod, and a first magnetic column is fixedly connected to the top of the end of the support plate away from the support rod.

[0014] Furthermore, a U-shaped frame is fixedly connected at equal intervals on one outer wall of the collection rack, a push rod is slidably connected to the U-shaped frame, and a counting plate is fixedly connected to the end of the push rod away from the U-shaped frame.

[0015] Furthermore, a second magnetic post is fixedly connected to the end of the push rod away from the counting plate via a connecting block, and the second magnetic post and the first magnetic post are magnetically repelled. A third spring is fixedly connected between the U-shaped frame and the connecting block, and the third spring is sleeved on the outside of the push rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) By setting up an egg-propelling component, when Silkie chickens enter or leave the chicken house, the pusher plate can move on the surface of the chicken nest, pushing the eggs on the surface of the chicken nest, so that the eggs are removed from the surface of the chicken nest and finally detached from the chicken nest. They fall one by one through the through hole at one end of the chicken nest and enter the collection rack for storage and statistics of Silkie chicken eggs. In this way, the staff does not need to put their hands into the inside of the chicken house to take the Silkie chicken eggs from the chicken nest. The Silkie chicken eggs can be detached from the chicken nest, thus avoiding the situation where the eggs slip or fall during the process of the staff taking the Silkie chicken eggs from the chicken nest, which would cause the eggs to be damaged and affect the subsequent breeding work.

[0018] (2) By setting an egg count component at one end of the bottom of the chicken coop, when the Silkie chicken lays an egg and it falls through the through hole with the help of the push plate, it will be transferred by the tilt of the transition frame so that the egg eventually rolls onto the collection rack, stores the eggs one by one, and arranges the eggs in an orderly manner, so as to facilitate the subsequent statistics of the Silkie chicken's egg production.

[0019] (3) When the eggs of Silkie chickens are transferred through the inclined transfer rack and finally neatly arranged on the collection rack, the weight of the eggs themselves causes the second spring to be compressed, which in turn causes the first magnetic column to move downward and away from the second magnetic column. Since the magnetic forces between the first and second magnetic columns are repulsive, when the first magnetic column moves away from the second magnetic column, the repulsive force on the second magnetic column gradually disappears. Under the elastic force of the third spring, the second magnetic column can be driven to move towards the position before the first magnetic column moved, which in turn causes the counting plate at the other end of the push rod to change position, indicating to the staff that there are Silkie chicken eggs stored there, so as to facilitate the staff to count and record the number of Silkie chicken eggs.

[0020] (4) After the egg production statistics of Silkie chickens are completed, since the collection rack is slidably connected to the fixed frame, the pull ring can be pulled outward to move the pull rod, and the collection rack can slide out of the fixed frame and eventually detach from the fixed frame, so that the collection rack can be taken out from the chicken house body, so as to facilitate the subsequent breeding work of the Silkie chickens' egg production.

[0032] 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.

[0033] Embodiments of the present invention

[0034] Please refer to Figures 1 to 9 As shown, it includes a chicken house body 1, a chicken coop 3 fixed inside the chicken house body 1, and an egg-boosting component connected inside the chicken house body 1.

[0035] The egg-boosting assembly includes a drive shaft 8 rotatably connected to the inner rear wall of the chicken house body 1. A turntable 9 is fixedly connected to the outer ring surface of the front end of the drive shaft 8. A connecting column 10 is fixedly connected to the front side of the turntable 9 off-center. A fixing plate 13 is fixedly connected to the inner top wall of the chicken house body 1. A linkage shaft 14 is rotatably connected between the fixing plate 13 and the inner rear wall of the chicken house body 1. A linkage frame 15 and a connecting frame 11 are fixedly connected in sequence to the outer ring surface of the linkage shaft 14. A connecting groove 12 is provided on the connecting frame 11. The connecting column 10 is movably connected in the connecting groove 12. A push plate 16 is fixedly connected to the end of the linkage frame 15 away from the linkage shaft 14. A drive motor is connected to the end of the drive shaft 8 away from the turntable 9 through the chicken house body 1. A switch 7 is provided on the inner bottom wall of the front side of the chicken house body 1, and the switch 7 is electrically connected to the drive motor. Slide rods 5 are symmetrically fixedly connected to the inner bottom wall of the front side of the chicken house body 1. A pressing plate 4 is slidably connected between the slide rods 5, and the pressing plate 4 is located above the switch 7.

[0036] A first spring 6 is fixedly connected between the pressing plate 4 and the inner bottom wall of the chicken house body 1, and the first spring 6 is sleeved on the outside of the slide rod 5.

[0037] A positioning block 2 is fixedly connected to one inner wall of the chicken house body 1, and magnetic blocks 17 are fixedly connected to the opposite sides of the positioning block 2 and the push plate 16.

[0038] The effects achieved by this embodiment are as follows: In the prior art, when it is necessary to collect and count the eggs laid by Silkie chickens in the nest 3, staff members need to reach into the chicken house body 1 to remove the eggs from the nest 3. However, since there is a certain distance between the nest 3 and the external environment, the eggs are prone to slipping or falling during the egg-removal process, leading to accidents and damage. Compared with the prior art, the egg-pushing component can push the pusher plate 16 to push the eggs on the surface of the nest 3 while the Silkie chickens are entering or leaving the chicken house body 1, thus removing the eggs from the nest 3. This eliminates the need for staff to reach into the chicken house body 1 to remove the eggs from the nest 3, preventing slipping or falling during egg removal and avoiding damage to the eggs, which could affect subsequent breeding work.

[0039] Please refer to Figures 1 to 9 As shown, a through hole 18 is provided at one end of the chicken coop 3 at equal intervals, and a connecting groove 19 is provided at one end of the bottom of the chicken coop 3. The connecting groove 19 is connected to the through hole 18. A transfer frame 20 is fixedly connected inside the connecting groove 19 at an incline. A fixed frame 21 is fixedly connected to the bottom front end of the transfer frame 20. An egg count component is connected to the fixed frame 21.

[0040] The egg counting component includes a collection rack 22, with slide plates 23 symmetrically fixedly connected to both sides of the collection rack 22, and the collection rack 22 is slidably connected to the fixed frame 21 via the slide plates 23. A pull ring 38 is fixedly connected to the front side of the collection rack 22 via a pull rod 37.

[0041] Egg slots 24 are evenly spaced on the collection rack 22. A second spring 26 is fixedly connected to the inner bottom wall of the egg slot 24. A tray 25 is fixedly connected to the other end of the second spring 26. An extension plate 27 is fixedly connected to the tray 25. A support plate 29 is fixedly connected to the bottom of the extension plate 27 through a support rod 28. A first magnetic column 30 is fixedly connected to the top of the end of the support plate 29 away from the support rod 28.

[0042] A U-shaped frame 31 is fixedly connected at equal intervals on one outer wall of the collection rack 22. A push rod 32 is slidably connected to the U-shaped frame 31. A counting plate 36 is fixedly connected to the end of the push rod 32 away from the U-shaped frame 31. A second magnetic column 34 is fixedly connected to the end of the push rod 32 away from the counting plate 36 through a connecting block 33. The second magnetic column 34 and the first magnetic column 30 are magnetically repelled. A third spring 35 is fixedly connected between the U-shaped frame 31 and the connecting block 33. The third spring 35 is sleeved on the outside of the push rod 32.

[0043] The effects achieved by this embodiment are as follows: In the prior art, when the staff takes the eggs out of the chicken coop 3, the staff still need to manually count the number of eggs laid by the Silkie chickens. The manual counting method is not only time-consuming and laborious, but also easily affected by the external environment, which can cause the staff to become distracted, resulting in deviations in the statistical results and requiring repeated recording. Compared with the prior art, the set egg counting component can not only store the eggs one by one after the push plate 16 is pushed away, so that the eggs can be arranged in an orderly manner, but also, when arranging, the weight of the eggs can be used to increase the distance between the first magnetic column 30 and the second magnetic column 34, so that the repulsive force on the second magnetic column 34 gradually decreases and disappears. Under the elastic force of the third spring 35, the push rod 32 drives the counting plate 36 to move and change its position synchronously, so that the counting plate 36 where the eggs are placed is deviated from other counting plates 36, so that the staff can quickly know the number of eggs stored on the collection rack 22.

[0044] Furthermore, since the collection rack 22 is installed on the fixed frame 21 by a sliding connection, when it is necessary to remove the eggs laid by the Silkie chickens on the collection rack 22, the collection rack 22 can be pulled outward to disengage from the fixed frame 21 and remove the collection rack 22 from the chicken house body 1, so as to facilitate the subsequent breeding work of the Silkie chickens' eggs.

[0045] The complete usage steps and working principle of the above embodiments are as follows:

[0046] When the selected Silkie chickens enter the chicken house 1, they first step on the pressing plate 4, causing both ends of the pressing plate 4 to slide downwards on the sliding rod 5. Simultaneously, the first spring 6 is compressed. At this time, when the pressing plate 4 is pressed against the inner bottom wall of the chicken house 1 by the weight of the Silkie chicken, it will press the switch 7 located below it. Since the switch 7 is electrically connected to the drive motor, when the switch 7 is pressed, the drive motor will start operating, causing the drive shaft 8 to rotate on the rear inner wall of the chicken house 1. Simultaneously, it will drive the turntable 9, which is coaxially mounted at its front end, to rotate around the drive shaft 8. Since the connecting column 10 is mounted off-center on the front surface of the turntable 9, and the connecting column 10 is movable... The connecting slot 12 opened on the connecting frame 11 is connected to the connecting column 10. When the connecting column 10 rotates synchronously with the rotation of the turntable 9 around the drive shaft 8, the position of the connecting column 10 will change accordingly. The connecting frame 11 will also reciprocate accordingly according to the movement of the position of the connecting column 10. Since the connecting frame 11 is fixed on the linkage shaft 14, and the linkage frame 15 is also fixed on the linkage shaft 14, when the connecting frame 11 reciprocates, the linkage frame 15 will be driven to reciprocate synchronously through the connection of the linkage shaft 14, thereby driving the push plate 16 to move on the chicken coop 3, pushing the eggs left on the chicken coop 3, and finally passing through the through hole 18 and leaving the surface of the chicken coop 3.

[0047] It should be noted that in the initial state, the push plate 16 and the positioning block 2 are positioned and connected by two magnetic blocks 17 that attract each other. When the drive motor is turned on, it will only drive the drive shaft 8 to rotate one revolution. Even if the push plate 16 is separated from the positioning block 2, passes over the surface of the chicken coop 3, and finally returns to the positioning block 2, it will be magnetically connected to the positioning block 2.

[0048] When the pusher plate 16 pushes the eggs on the surface of the chicken coop 3 and they fall off the surface of the chicken coop 3 through the through hole 18, the eggs will first enter the connecting groove 19 connected to the through hole 18 and finally fall on the transfer rack 20. Since the transfer rack 20 is installed at an angle, the eggs will roll on the transfer rack 20 under the force of the angle and finally enter the interior of the collection rack 22. It should be noted that the bottom surface of the egg that is in contact with the collection rack 22 is inclined, which can provide the inclined force for the egg to roll, so that the egg can roll at an angle on the collection rack 22 as it does on the transfer rack 20.

[0049] The first egg to enter will roll to the front of the collection rack 22 with the support of the inclined plane. When the egg stops rolling due to the obstruction at the front of the collection rack 22, it will be exactly on the egg slot 24. Through the weight of the egg itself, it will press the tray 25 in the egg slot 24 downward, causing the second spring 26 to compress. This will simultaneously drive the extension plate 27 to move downward. With the connection of the support plate 29, the first magnetic column 30 will move downward synchronously. Since the right side of the first magnetic column 30 is provided with a second magnetic column 34 that is magnetically repelled by it, and a connecting block 33 is installed on the second magnetic column 34, the connecting block 33 and the U-shaped frame 31 are connected by a third spring 35 and a push rod 32. When the first... As the first magnetic column 30 moves downward, the repulsive force on the second magnetic column 34 gradually disappears. Under the elastic force of the third spring 35, the second magnetic column 34 is pushed towards the position before the first magnetic column 30 moves, simultaneously driving the push rod 32 to move in the same direction on the U-shaped frame 31. Since the other end of the push rod 32 is connected to the counting board 36, the counting board 36 will also move when the push rod 32 moves, creating a positional deviation between it and the counting board 36 set behind it. This allows the staff to quickly identify the number of eggs stored in the collection rack 22, thereby facilitating the staff's work of counting and recording the number of eggs laid by Silkie chickens.

[0050] As the first egg positions and presses the tray 25, causing the corresponding counting plate 36 to move and change position, subsequent eggs also roll onto the collection rack 22 in sequence. Guided by the inclined surface and supported by the preceding eggs, subsequent eggs can be placed in the egg slots 24 opened on the collection rack 22, and press the tray 25 accordingly, causing the corresponding counting plate 36 to move and change position, thereby indicating to the staff that there is an egg placed at the counting plate 36, so that the staff can count and record the eggs.

[0051] When the number of eggs laid by Silkie chickens is counted and the eggs need to be removed for subsequent breeding research, the pull ring 38 can be pulled outward to move the pull rod 37 forward. Simultaneously, the collection rack 22 moves forward on the fixed frame 21 via the slide plate 23, and finally the collection rack 22 is separated from the fixed frame 21, making it convenient for staff to remove the collection rack 22 from the chicken house body 1 and carry out the subsequent egg removal work.

[0052] When the collection rack 22 is removed and the eggs placed on it are taken out, the pressure on the tray 25 disappears as the eggs detach from the rack 22. Simultaneously, the compressive force on the second spring 26 also disappears. Under the elastic force of the second spring 26, the tray 25 extends upwards, causing it to lift. With the extension plate 27 connected, the support rod 28 moves synchronously, and with the support plate 29 connected, the first magnetic column 30 moves synchronously upwards, following the movement of the tray 25. The magnetic pillars 30 and 34 repel each other. When the first magnetic pillar 30 moves upward, the magnetic repulsion drives the second magnetic pillar 34 to move away from the first magnetic pillar 30. Simultaneously, the push rod 32 moves outward, squeezing the third spring 35 and compressing it. As the push rod 32 moves outward, the counter 36 also moves outward, thus achieving a reset. When all the eggs on the collection rack 22 have been taken, the counter 36 will finally stop on the same axis.

[0053] The circuits and controls involved in this invention are all existing technologies and will not be described in detail here.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
