An entrance gate structure and control method for preventing simultaneous entry of multiple birds

Abstract

The application discloses an entrance door structure and a control method for preventing multiple birds from entering simultaneously. The entrance door structure comprises a passageway and three sequentially connected folding plates arranged on the passageway. The surfaces of the three sequentially connected folding plates are perpendicular to the ground of the passageway. One side of the passageway and the three folding plates form a trapezoidal body. The first folding plate and the third folding plate are telescopic plates. The telescopic distance between the two plates determines the distance between the second folding plate and the other side of the passageway, thereby limiting the body width of the birds passing through the passageway. The application also discloses a control method for the entrance door structure. The method is realized by positioning a rotating door and cooperating with a sensor. When the sensor detects the first bird entering the passageway, the control motor is triggered to close the positioning rotating door, thereby limiting the following birds from entering and ensuring that only one bird enters. The application is convenient for limiting single birds to enter a measuring station or an enclosed structure.

Description

Technical Field

[0001] This invention relates to the field of poultry breeding technology, and in particular to an entrance gate structure and control method for a poultry testing station that prevents multiple birds from entering at the same time. Background Technology

[0002] When breeding poultry are feeding, two or more individuals may simultaneously and rapidly switch feeding ports to compete for food. This makes it difficult for the short-time measurement system to distinguish and lock the feed intake and weight data. Consequently, it is impossible to accurately monitor the feed-to-meat ratio data at each stage of the breeding poultry's growth cycle and achieve maximum production benefits.

[0003] In addition, given the mobility of breeding poultry and the need to perform procedures such as vaccinating individual breeding poultry, it is necessary to develop an entrance gate structure for capturing individual breeding poultry in group settings. Summary of the Invention

[0004] To facilitate limiting entry of individual birds into the testing station or enclosed structure.

[0005] On the one hand, the present invention provides an entrance gate structure to prevent multiple birds from entering at the same time, which includes a channel and three folding plates that are sequentially movably connected on the channel;

[0006] The three folding plates connected in sequence are perpendicular to the floor of the passage. One side of the passage and the three folding plates form a trapezoid. The first and third folding plates are retractable. The retraction of these two plates determines the distance between the second folding plate and the other side of the passage, thus limiting the width of the passage for birds to pass through.

[0007] Preferably, the retractable plate includes a guide plate and a sliding plate. One side of the guide plate is hinged to the second folding plate. A guide hole is horizontally provided on the surface of the guide plate. A circular hole that can move coaxially along the guide hole is provided on the sliding plate. The guide plate and the sliding plate are fixedly connected by a fastener passing through the circular hole and the guide hole. The position of the circular hole in the length direction of the guide hole is adjustable, thereby adjusting the actual width of the guide plate and the sliding plate after they are fixed.

[0008] Furthermore, a support frame is provided on the second folding plate, and a positioning rotating door is provided on the support frame. A motor drives a push-pull device to control the positioning rotating door to open or close the passage.

[0009] Preferably, the positioning revolving door includes a door shaft, one end of which is connected to the lower part of the rod body via a connecting member, and the other end of the door shaft consists of a door shaft positioning bushing, a bearing, and a swing arm positioning bushing arranged sequentially from bottom to top.

[0010] Preferably, the push-pull device includes a first T-shaped plate and a second T-shaped plate, with two push-pull guide rods arranged in parallel and spaced apart between the two T-shaped plates. A swing arm positioning bushing is positioned on the revolving door. The end of the swing arm is rotatably connected to a pulley axle. The grooves at both ends of the pulley diameter are correspondingly matched with the two push-pull guide rods. A rotating shaft below the pulley axle is connected to one end of a tension spring connecting plate. The free end of the tension spring connecting plate is inserted into a guide hole provided below the first T-shaped plate. The free end of the swing arm of the swing arm positioning bushing is connected to the rotating shaft of the pulley axle. As the pulley slides between the two push-pull guide rods, the tension spring connecting plate on the pulley axle is pulled out and pulled in the guide hole of the first T-shaped plate, ensuring that the pulley can slide stably between the two T-shaped plates under the guidance of the two push-pull guide rods and the tension spring connecting plate.

[0011] Furthermore, a tension spring connection point is provided on the free end of the tension spring connecting plate, or on the tension spring connecting plate at its maximum distance between the two T-shaped plates, on the outer side of the first T-shaped plate, and another connection point of the tension spring is provided on the second T-shaped plate. The tension spring is used to reset the swing arm of the swing arm positioning bushing connected to the door shaft, thereby resetting the entrance door.

[0012] Preferably, the support frame includes two vertical rods, with a motor cover between the top ends of the two rods for holding the motor. Two guide rods are arranged parallel above the second folding plate. The upper sides of the motor cover are connected to the two guide rods by U-shaped plates. The U-shaped groove of the U-shaped plate is snapped onto the two guide rods, allowing the motor cover to slide along the guide rods and follow the second folding plate through the channel width adjustment.

[0013] Furthermore, an ear plate is provided on one side below the motor cover, and one end of the cable that supplies power to the motor is fixedly connected to the ear plate. As the motor cover moves, the cable can be wound up accordingly.

[0014] Alternatively, the passageway can be a trestle, a bridge, or a passageway that is enclosed in all directions and can be accessed from the front and back.

[0015] On the other hand, the present invention provides a control method for an entrance gate structure that prevents multiple birds from entering simultaneously, comprising:

[0016] The pulley slides along the track inside the push-pull device. The pulley axle is connected to the tension spring connecting plate, and its free end is pulled out within the plate surface on the side opposite to the limiting baffle at one end of the track of the push-pull device. A connecting tension spring is provided between the limiting baffle and the free end of the tension spring connecting plate.

[0017] When the first bird is detected, a control signal is generated to drive the push-pull device to move from the first position to the second position. The pulley and the limit baffle of the push-pull device are separated from the contact state. Due to the separation and movement, the pulley is in the original position, and the tension spring is pulled open and extended.

[0018] When the tension spring undergoes contraction deformation, the tension spring connecting plate is forced to move towards the second position under the contraction force of the tension spring. The tension spring connecting plate drives the pulley to move towards the limit baffle and abut against it.

[0019] The door hinge arm, connected to the pulley axle, rotates from its initial position to a fixed position, thereby causing the entrance door connected to the door hinge to close from the open state.

[0020] Beneficial effects

[0021] This invention provides an entrance gate structure to prevent multiple birds from entering simultaneously. This structure employs three sequentially connected folding plates along the bird passage. The movable connection of these plates alters the height of the trapezoidal shape formed by the three folding plates and one side of the passage. This adjusts the width of the passage between the second folding plate and the other side of the passage, restricting passage to only one bird at a time. The first and last folding plates are retractable, and their extension or retraction determines the distance between the second folding plate and the other side of the passage, further limiting the width of the bird passing through. This accommodates the varying body shapes of birds at different growth stages, further refining the restriction to single-bird passage. The control method for this entrance gate structure involves a positioning rotating door on the second folding plate in conjunction with a sensor. Once the sensor detects the first bird entering the passage, it triggers a control motor to close the positioning rotating door, preventing subsequent birds from entering and ensuring only one bird can pass at a time.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In various embodiments of the present invention, the poultry can be ducks, geese, mandarin ducks, chickens, pigeons, or other poultry, with ducks being the preferred choice.

[0034] See Figure 1 This invention provides an entrance door structure to prevent multiple birds from entering simultaneously. The entrance door structure includes a passageway and three folding panels connected by sequential hinges on the passageway.

[0035] The passageway can be a trestle, a bridge, or an enclosed passageway that allows passage in all directions. In this embodiment, a trestle is preferred. The entrance to the trestle is connected to the ground by an entrance ramp or steps, and the exit of the trestle connects to the entrance of the measuring station or the entrance of other enclosed spaces.

[0036] The three folding panels connected in sequence are perpendicular to the bridge deck. The longitudinal side of the first folding panel 11 is connected to the first support rod 31 of the bridge deck 2, and the longitudinal side of the third folding panel 13 is connected to the second support rod 33 of the bridge deck. The support panel 14 on one side of the bridge deck, together with the three folding panels 11, 12, and 13, forms a trapezoid. The movable connection of the folding panels can change the height of the trapezoid formed by the support panel 14 and the three folding panels, that is, it can adjust the width of the passage between the second folding panel and the opposite side of the bridge support panel 14, restricting the passage to only one bird at a time.

[0037] The first folding plate includes a guide plate 111 and a sliding plate 112. One side of the guide plate is hinged to the second folding plate 12. A horizontal guide hole 1110 is provided on the surface of the guide plate. One side of the sliding plate is connected to the first support rod. A circular hole 1120 that can move coaxially along the guide hole is provided on the sliding plate. The guide plate 111 and the sliding plate 112 are fixedly connected by bolts passing through the circular hole 1120 and the guide hole 1110 and nuts. The position of the circular hole in the length direction of the guide hole is adjustable, thereby adjusting the actual usable width after the guide plate and the sliding plate are fixed. The structure of the first folding plate and the third folding plate is the same, and will not be described again. The adjustability of the width of the first folding plate and the third folding plate determines the width of the gap between the second folding plate and the suspended side of the pier, that is, the width of the actual passage width for birds to enter the pier. This adapts to the size of birds at different stages of growth, ensuring that the actual passage width of the pier can only accommodate the body width of one bird, and preventing multiple birds from entering at the same time. If the passageway is a boardwalk, multiple ducks crossing the boardwalk will push any extra ducks off one side of the boardwalk. Preferably, the guide plate surface is provided with pairs of elongated guide holes 1110 on the top and bottom, and the sliding plate surface is provided with corresponding pairs of round holes 1120 to ensure the stability of the connection between the two plate surfaces.

[0038] A support frame is fixedly installed on the second folding plate 12. The support frame includes two vertical rods 32, with a motor cover 4 between the tops of the two rods to hold the motor. A positioning revolving door is installed on the vertical rod 32 near the entrance of the trestle bridge. This positioning revolving door includes a door shaft 5. One end of the door shaft is connected to the lower part of the rod 32 via a connector 51. The other end of the door shaft consists of a door shaft positioning sleeve 510, a bearing 520, and a swing arm positioning sleeve 530 arranged sequentially from bottom to top. The housing of the bearing 520 is fixedly connected to the upper part of the rod 32 via the connector 52. A push-pull device driven by a motor 40 causes the swing arm of the swing arm positioning sleeve 530 to rotate, thereby driving the door shaft to rotate. The entrance door 6, which is fixedly connected to the side of the door shaft, opens and closes with the rotation of the door shaft. The structure of the entrance door is the same as that of the first folding plate, consisting of a guide plate and a sliding plate, and the width of the entrance door can be adjusted.

[0039] The push-pull device includes a first T-shaped plate 71, a second T-shaped plate 72, and two push-pull guide rods 73 arranged in parallel and spaced apart between the two T-shaped plates. The free end of the swing arm 531 of the swing arm positioning bushing 530 is rotatably connected to a pulley 74 axle. The grooves at both ends of the pulley diameter are correspondingly matched with the two push-pull guide rods 73. The shaft below the pulley axle is connected to one end of a tension spring connecting plate 75. The other end (free end) of the tension spring connecting plate is inserted into the guide groove or guide hole 710 provided below the first T-shaped plate. As the pulley slides between the two push-pull guide rods, the tension spring connecting plate on the pulley axle is pulled out and pulled in the guide hole of the first T-shaped plate, ensuring that the pulley can slide stably between the two T-shaped plates under the three-point guidance of the two push-pull guide rods and the tension spring connecting plate. A tension spring (not shown) connection point is provided on the free end of the tension spring connecting plate, or on the tension spring connecting plate at its maximum distance between the two T-shaped plates. Another connection point of the tension spring is provided on the lower end of the second T-shaped plate. This tension spring is used to reset the swing arm of the swing arm positioning bushing connected to the door hinge, thereby resetting the entrance door. The tension spring also has the function of flexibly closing the entrance door to prevent it from getting stuck and injuring the ducks.

[0040] The motor output shaft is connected to a motor swing arm 41 via a spherical bearing. The first T-shaped plate is connected to the motor swing arm via a connecting shaft. When the swing arm 531 is in its initial position (as per the positioning sleeve 530), the second T-shaped plate abuts against the pulley, the tension spring is at its initial length without external force, and the entrance door connected by the door hinge is open. At this time, ducks can enter the entrance door. When an infrared sensor inside the passage detects the first duck entering, it triggers a control signal to control the motor 40 to drive the motor swing arm 41 to rotate, pushing the first T-shaped plate, the two push-pull guide rods, and the second T-shaped plate to move horizontally from the initial first position to the second position. The axle connection point is close to the guide hole of the first T-plate. The second T-plate changes from a state of contact with the pulley to a state of separation from the pulley, and the tension spring is pulled open. Then, because the swing arm of the swing arm positioning bushing loses the limiting effect of the second T-plate on the pulley, the pulled-open tension spring undergoes contraction deformation. Under the contraction tension of the tension spring, the tension spring connecting plate is forced to move towards the second position. The tension spring connecting plate drives the pulley to move towards the second T-plate, thereby driving the swing arm of the swing arm positioning bushing to rotate to a certain position. The linkage door shaft rotates to close the entrance door 6, which can prevent multiple ducks following the first duck from entering.

[0041] When the duck passes through the entrance gate structure and completes a measurement event, a control signal is triggered, controlling the motor to rotate in the opposite direction. The motor swing arm rotates in the opposite direction, pulling the first T-shaped plate, the two push-pull guide rods, and the second T-shaped plate from the second position to the initial first position. During this process, the pulley is always in contact with the second T-shaped plate. The pulley drives the swing arm of the swing arm positioning bushing to rotate from the fixed position to the initial position. The linkage gate shaft rotates until the entrance gate 6 opens, starting the next event.

[0042] The system senses the first duck entering the passage, triggering a control signal to drive the motor to close the entrance gate. Once a duck passes through the entrance gate, completing one measurement event, the control signal is triggered to open the entrance gate. Only one duck is allowed to enter the measurement station at a time for data collection on its weight and feed intake. The duck leaves the station, completing one measurement event. During this event, the measurement is conducted within a closed measurement station, hence the entrance gate remains closed to prevent other ducks from entering and interfering with the data collection.

[0043] Two guide rods 8 are parallel to each other above the second folding plate. The lugs on both sides of the motor cover are connected between the two guide rods by U-shaped plates. The U-shaped groove of the U-shaped plate 81 is fastened above the two guide rods, allowing the motor cover to slide along the guide rods. By adjusting the width of the second folding plate on the platform, the motor cover slides on the two guide rods to a suitable position. An ear plate is set on one side of the lower part of the motor cover. One end of the power supply cable for the motor is fixedly connected to the ear plate. As the motor cover moves, the cable can be wound up accordingly.

[0044] Embodiment 2 of the present invention provides a control method for an entrance gate structure that prevents multiple poultry from entering simultaneously. Based on Embodiment 1, the method includes the following steps:

[0045] S100: The pulley slides along the track inside the push-pull device. The pulley axle is connected to the tension spring connecting plate, and its free end is pulled out within the plate surface on the side opposite to the limiting baffle at one end of the track of the push-pull device. A connecting tension spring is provided between the limiting baffle and the end of the free end of the tension spring connecting plate.

[0046] In this step, the limiting baffle is the second T-shaped plate, and the plate surface on the opposite side of the limiting baffle is the first T-shaped plate.

[0047] S200: When the first duck is detected, a control signal is generated to drive the push-pull device to move from the first position to the second position. The pulley and the limit baffle of the push-pull device are separated from the contact state. Due to the separation and movement, the pulley is in the original position, and the tension spring is pulled open and extended.

[0048] In this step, the first duck is detected by an infrared sensor, triggering a control signal.

[0049] S300: When the tension spring undergoes contraction deformation, the tension spring connecting plate is forced to move towards the second position under the tension of the tension spring. The tension spring connecting plate drives the pulley to move towards the limit baffle and abut against it.

[0050] In this step, the tension spring has the function of pulling and closing the entrance door, and at the same time, it also has the function of flexibly closing the entrance door and elastic buffering to prevent the ducks from being pinched or injured.

[0051] S400: The door hinge arm connected to the pulley axle rotates from its initial position to a fixed position, thereby causing the entrance door connected to the door hinge to close from the open state. This keeps the following ducks out of the door, limiting the passage to one duck at a time.

[0052] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
