Description

Automatic opening and closing gate device for poultry fence

The present invention relates to an automatic gate opening and closing device for a poultry house fence, and more particularly to an automatic gate opening and closing device for a poultry house fence that allows a poultry house (such as a chicken house) robot to move smoothly between different areas of the poultry house.

With the rapid development of smart agriculture in recent years, poultry house robots have been gradually applied to poultry farms to assist in farm management. For example, a chicken disturbance robot can be used in a flat chicken house to drive the chickens to get up and move around during the patrol process to reduce fighting among the chickens, prevent the chickens from squatting for a long time and affecting their health, and promote the chickens to eat, etc. Or an environmental monitoring robot can be used to collect various environmental data of the chicken house (such as temperature, humidity, etc.) during the patrol process to monitor whether the chicken house environment is suitable, etc.

Taking chicken coops as an example, due to the different characteristics of chickens (such as gender, growth age, body size, etc.), chicken farmers usually use iron fences (partitions) about 80 cm high to divide each chicken farm into several areas and raise chickens in different areas. Fences can prevent chickens from mixing and are easy to manage, but they will also hinder the above-mentioned poultry house robots from moving across areas to perform management tasks such as patrolling or collecting data. In other words, fences will affect the range of activities of poultry house robots, reduce the feasibility of practical application of poultry house robots, and significantly reduce the willingness of operators to introduce poultry house robots.

In order to solve the above-mentioned problems of poultry houses, the present invention proposes an automatic opening and closing gate device for poultry house fences. The gate structure is designed so that when a poultry house robot approaches, a controller can control the gate structure to automatically open and close the gate structure, so that the poultry house robot can smoothly pass through the fences and move across areas to perform management tasks such as patrolling or collecting data, thereby improving the convenience of poultry house management.

The poultry fence automatic opening and closing gate device proposed in the present invention comprises a frame, two opening and closing gate structures, a first driving structure, a second driving structure and a controller, wherein the frame is in a rectangular shape and has two side frames arranged in parallel with each other in front and rear, each of the two side frames comprises two guide groove transverse frames arranged in parallel with each other in the upper and lower directions and two longitudinal frames arranged in parallel with each other in the left and right directions, and the two side frames are respectively defined with a longitudinal center line overlapping with each other.

In addition, the two opening and closing gate structures are respectively arranged on the two side frames, and each of the two opening and closing gate structures includes a first double-leaf outward folding gate and a second double-leaf outward folding gate. The first double-leaf outward folding gate includes two first door panels pivoted to each other, one of the two first door panels is pivoted to one of the two longitudinal frames, the other of the two first door panels is slidably arranged on the two guide groove transverse frames, and the first double-leaf outward folding gate covers the area from one of the two longitudinal frames pivoted to the longitudinal center line. The second double-leaf outward folding gate includes two second door panels pivoted to each other, one of the two second door panels is pivoted to the other of the two longitudinal frames, the other of the two second door panels is slidably disposed on the two guide groove transverse frames, and the second double-leaf outward folding gate covers the area from the other of the two longitudinal frames pivoted to the longitudinal center line.

Furthermore, the first driving structure includes a first linear actuator, a first driving connecting rod and two first connecting connecting rods. The first linear actuator is disposed on the frame; the first driving connecting rod is connected to the first linear actuator and slides relative to the frame; the two first connecting connecting rods are respectively pivoted to two ends of the first driving connecting rod and are respectively pivoted to one of the two first door panels of the first double-leaf outward folding gate of the two opening and closing gate structures pivoted to one of the two longitudinal frames.

Similarly, the second driving structure comprises a second linear actuator, a second driving connecting rod and two second connecting connecting rods. The second linear actuator is disposed on the frame; the second driving connecting rod is connected to the second linear actuator and slides relative to the frame; the two second connecting connecting rods are respectively pivoted to the two ends of the second driving connecting rod and are respectively pivoted to one of the two second door panels of the second double-leaf outward folding gate of the two opening and closing gate structures pivoted to the other of the two longitudinal frames;

In addition, the controller is disposed on the frame and is electrically connected to the first linear actuator and the second linear actuator respectively.

As described above, when the poultry house robot approaches the automatic gate opening and closing device of the poultry house partition, the controller can know that the poultry house robot wants to move across the partition. At this time, the controller will control the first double-leaf outward folding gate and the second double-leaf outward folding gate to open and close, so as to achieve the purpose of allowing the poultry house robot to move across areas smoothly, so that the poultry house robot can easily perform management work in different areas of the poultry house, thereby improving the convenience of poultry house management.

In one implementation, the controller includes a wireless communication module, a control module, an IO control module and a power module electrically connected to each other.

In one embodiment, the poultry fence automatic opening and closing gate device further comprises two positioning tags which are respectively arranged outwardly on the two opening and closing gate structures and respectively located on the longitudinal center line, and the controller is electrically connected to the two positioning tags.

In one implementation, the first linear actuator and the second linear actuator are respectively a pneumatic cylinder, or a hydraulic cylinder, or an electric cylinder.

In one embodiment, the poultry house fence automatic gate opening and closing device further comprises a warning device, which is arranged on the frame and electrically connected to the controller. The warning device is a sound warning device, or a light warning device, or both.

The environmental sensor can collect comprehensive environmental data in the poultry house 9, and the wireless transmission technology can be used to wirelessly transmit the collected environmental data to the computer equipment held by people, so that people can immediately know the environmental conditions of the poultry house 9 and the activity conditions of the chickens 91 without entering the poultry house 9, thereby facilitating people to manage the poultry house 9.

As shown in FIG. 1 , in order to facilitate the poultry house robot 8 to move between different areas of the poultry house 9, a poultry house fence automatic gate opening and closing device 1 is provided on the fence 90 between adjacent areas. When the poultry house robot 8 approaches the poultry house fence automatic gate opening and closing device 1, the poultry house fence automatic gate opening and closing device 1 can utilize the structural design described below to perform the gate opening and closing action, so that the poultry house robot 8 can move smoothly across areas to perform management tasks such as patrolling or collecting data.

Please refer to Figures 2 to 4 simultaneously, wherein Figure 2 is a three-dimensional diagram of a preferred specific embodiment of the present invention, Figure 3 is a three-dimensional diagram of Figure 2 with the door panel removed, and Figure 4 is a three-dimensional diagram of Figure 3 from another viewing angle.

FIG. 2 to FIG. 4 show an automatic opening and closing gate device 1 for a poultry house partition installed in the partition 90 as shown in FIG. 1, and the automatic opening and closing gate device 1 for a poultry house partition includes a frame 2 in the shape of a rectangle, such as a long rectangle as shown in the figure, and the frame 2 has two side frames 21 arranged in parallel with each other in the front and rear directions, each of the two side frames 21 includes two guide groove transverse frames 22 arranged in parallel with each other in the upper and lower directions (as shown in FIG. 4, which shows the guide groove structure design) and two longitudinal frames 23 arranged in parallel with each other in the left and right directions, and the two side frames 21 respectively define a longitudinal center line 20 that overlaps with each other, that is, if viewed from the front side (or the rear side), the longitudinal center line 20 of the two side frames 21 is an overlapping line.

As can be seen from FIGS. 2 to 4 , the poultry fence automatic opening and closing gate device 1 further includes two opening and closing gate structures 3 , which are respectively disposed on two side frames 21 , and each of the two opening and closing gate structures 3 includes a first double-piece outward folding gate 31 and a second double-piece outward folding gate 32 .

In this embodiment, the two-opening gate structure 3 has a width and a height respectively, and the width is between 85 cm and 108 cm, and the height is between 82 cm and 102 cm. The above-mentioned height can be roughly consistent with the height of the fence 90 (please refer to Figure 1) in practical design, so there will be no visual incongruity.

The first double-leaf outward folding gate 31 includes two first door panels 311 pivoted to each other, and one of the two first door panels 311 is pivoted to one of the two longitudinal frames 23, and the other of the two first door panels 311 is slidably disposed on the two guide groove transverse frames 22, and the first double-leaf outward folding gate 31 covers the area from one of the two pivoted longitudinal frames 23 to the longitudinal center line 20.

Similarly, the second double-leaf outward folding gate 32 includes two second door panels 321 pivoted to each other, and one of the two second door panels 321 is pivoted to the other of the two longitudinal frames 23, the other of the two second door panels 321 is slidably disposed on the two guide groove transverse frames 22, and the second double-leaf outward folding gate 32 covers the area from the other of the two pivoted longitudinal frames 23 to the longitudinal centerline 20.

Figures 2 to 4 further show that the poultry fence automatic opening and closing gate device 1 includes a first driving structure 41 and a second driving structure 42. The first driving structure 41 and the second driving structure 42 can be used to drive the first door panels 311 of the first double-leaf outward folding gate 31 and the second door panels 321 of the second double-leaf outward folding gate 32 to open and close.

In detail, the first driving structure 41 includes a first linear actuator 411, a first driving connecting rod 412 and two first connecting connecting rods 413. The first linear actuator 411 is disposed on the frame 2; the first driving connecting rod 412 is linked to the first linear actuator 411 and slides relative to the frame 2; the two first connecting connecting rods 413 are respectively pivoted to the two ends of the first driving connecting rod 412 and are respectively pivoted to one of the two first door panels 311 of the first double-leaf outward folding gate 31 of the two opening and closing gate structures 3 pivoted to one of the two longitudinal frames 23.

Similarly, the second driving structure 42 includes a second linear actuator 421, a second driving connecting rod 422 and two second connecting connecting rods 423. The second linear actuator 421 is disposed on the frame 2; the second driving connecting rod 422 is linked to the second linear actuator 421 and slides relative to the frame 2; the two second connecting connecting rods 423 are respectively pivoted to the two ends of the second driving connecting rod 422 and are respectively pivoted to one of the two second door panels 321 of the second double-leaf outward folding gate 32 of the two-opening gate structure 3 pivoted to the other of the two longitudinal frames 23.

In this embodiment, the first linear actuator 411 and the second linear actuator 421 are respectively a pneumatic cylinder, and may also be a hydraulic cylinder, or may be other linear drive mechanisms (screw, slide rail, etc.) such as an electric cylinder.

In addition, the first driving structure 41, the second driving structure 42 and the first door panel 311 and the second door panel 321 connected thereto can form a double crank slider mechanism design in terms of structure. This mechanism design can magnify the slider movement distance by about two times, thereby reducing the space required for the entire poultry house fence automatic opening and closing gate device 1.

As can be seen from Figures 2 to 4, the poultry fence automatic opening and closing gate device 1 includes two positioning tags 5 and a controller 6. The two positioning tags 5 are respectively arranged outwardly on the two opening and closing gate structures 3 and are respectively located at the longitudinal center line 20, that is, the two positioning tags 5 are respectively located at the center of the two opening and closing gate structures 3; the controller 6 is arranged on the frame 2 and is respectively electrically connected to the first linear actuator 411, the second linear actuator 421 and the two positioning tags 5.

Please refer to Figures 5 to 7 simultaneously, wherein Figure 5 is one of the top views of the preferred specific embodiment of the present invention, Figure 6 is the second top view of the preferred specific embodiment of the present invention, and Figure 7 is the third top view of the preferred specific embodiment of the present invention.

FIG. 5 to FIG. 7 sequentially show the operating states of the first double-leaf outward folding gate 31 and the second double-leaf outward folding gate 32. Among them, FIG. 5 shows that the first door panel 311 and the second door panel 321 (please refer to FIG. 2) are in a closed state; FIG. 6 shows that the first door panel 311 and the second door panel 321 begin to fold outward, that is, the first linear actuator 411 and the second linear actuator 421 respectively link the first driving connecting rod 412 and the second driving connecting rod 422 to slide relative to the frame 2, as shown by the arrows in the middle of FIG. 6, and when the first driving connecting rod 412 and the second driving connecting rod 422 slide relative to the frame 2, they will drive the first connecting connecting rod 413 and the second connecting connecting rod 423 respectively, as shown by the arrows on both sides of FIG. 6. The connecting rod 423 then drives the first door panel 311 and the second door panel 321 respectively. Since the first door panel 311 and the second door panel 321 not pivoted by the first connecting rod 413 and the second connecting rod 423 are pivoted with the first door panel 311 and the second door panel 321 pivoted by the first connecting rod 413 and the second connecting rod 423, and are slidably disposed on the guide groove transverse frame 22, the first door panel 311 and the second door panel 321 will produce an outward folding action; Figure 7 shows the state of the first door panel 311 and the second door panel 321 after being folded outward, at this time, the first door panel 311 and the second door panel 321 are in a fully open state.

Please refer to FIG. 6 , which shows an area 30. When the first door panel 311 and the second door panel 321 are folded outward, the above-mentioned structural design will ensure that the outward folding action of the first door panel 311 and the second door panel 321 will not interfere with the area 30. In other words, the poultry house robot 8 shown in FIG. 1 will move to the area 30 when passing through the poultry house fence automatic opening and closing gate device 1, as described in detail below.

Please refer to Figure 8, which is a system architecture diagram of a preferred specific embodiment of the present invention, and please also refer to Figure 2. The controller 6 disposed on the frame 2 includes a wireless communication module 61, a control module 62, an IO control module 63 (controlling power input and output, such as relays, motor drivers, etc.) and a power module 64 that are electrically connected to each other. The poultry house robot 8 performs wireless communication through the wireless communication module 61 so that the controller 6 knows that the poultry house robot 8 has approached the poultry house fence automatic opening and closing gate device 1 and intends to pass through the first door panel 311 and the second door panel 321. At this time, the controller 6 uses the control module 62 and the IO control module 63 to control the first linear actuator 411 and the second linear actuator 421 to start actuation, so that the first door panel 311 and the second door panel 321 (gate mechanism) perform an opening and closing action.

The frame 2 may be further provided with an alarm device 7 which is electrically connected to the controller 6. In the present embodiment, the alarm device 7 is a light alarm device (warning light), and of course, it may also be a sound alarm device, or both. When the first door panel 311 and the second door panel 321 are opening and closing, the alarm device 7 may inform people through light (or sound) that the first door panel 311 and the second door panel 321 are opening and closing.

As shown in FIG. 8 , in practical operation, an electronic mobile device 81 (such as a laptop, a tablet computer, a smart phone, etc.) can also be used to control the opening and closing actions of the first door panel 311 and the second door panel 321 .

Please refer to Figure 9, which is one of the schematic diagrams of the implementation status of the preferred specific embodiment of the present invention, and please also refer to Figures 2, 3 and 8. It is shown that there is a poultry house robot 8 in a poultry house 9 (such as a chicken house in the present embodiment) to perform management tasks such as disturbance of chickens 91 or environmental data collection. When the poultry house robot 8 is to move across regions, the poultry house robot 8 moves close to the poultry house fence automatic opening and closing gate device 1 set on the fence 90. The poultry house robot 8 is close to the wireless communication module 61 at this time and communicates wirelessly with the controller 6, so that the controller 6 knows that the poultry house robot 8 has approached the poultry house fence automatic opening and closing gate device 1 and intends to pass through the opening and closing gate structure 3. When the poultry house robot 8 approaches the opening and closing gate structure 3, the positioning tag 5 can be used to assist the poultry house robot 8 to move to a fixed position.

The positioning tag 5 is a visual identification tag, such as AprilTag, and the poultry house robot 8 may be provided with a visual identification system 80. When the poultry house robot 8 moves close to the poultry house fence automatic gate opening and closing device 1, the visual identification system 80 is used to identify the positioning tag 5 and wirelessly communicate with the controller 6. In addition, since the positioning tag 5 is located at the longitudinal center line 20 (please refer to FIG. 2), the poultry house robot 8 can simultaneously perform path correction to achieve positioning when moving close to the poultry house fence automatic gate opening and closing device 1.

Please refer to FIG. 10, which is a second schematic diagram of the preferred embodiment of the present invention, and also refer to FIG. 2, FIG. 3, FIG. 6 and FIG. 8. The poultry house robot 8 then moves to an area 30 where it will not be interfered with by the opening action of the first door panel 311 and the second door panel 321 (e.g., hit by the first door panel 311 and the second door panel 321). This area 30 is very close to the first door panel 311 and the second door panel 321 (as shown in FIG. 6), so the poultry house robot 8 can first drive away the chickens 91 located in front of the first door panel 311 and the second door panel 321 when moving to this area 30.

Next, the controller 6 uses the control module 62 and the IO control module 63 to control the first linear actuator 411 and the second linear actuator 421 to start operating, so that the first door panel 311 and the second door panel 321 are opened. Please note that since the first door panel 311 and the second door panel 321 are folded outward, when the first door panel 311 and the second door panel 321 are opened, the chickens 91 adjacent to the first door panel 311 and the second door panel 321 (for example, the chickens 91 located at the upper left in FIG. 10 ) will be pushed away to prevent the chickens 91 from following the poultry house robot 8 to move across areas.

Please refer to Figure 11, which is a third schematic diagram of the preferred embodiment of the present invention, and please also refer to Figures 2 and 3. When the first door panel 311 and the second door panel 321 are folded outward and fully opened, the poultry house robot 8 begins to move across the area through the poultry house fence automatic gate opening and closing device 1.

Please refer to Fig. 12, which is a fourth schematic diagram of the preferred embodiment of the present invention, and also refer to Fig. 2 and Fig. 3. When the poultry house robot 8 passes through the poultry house fence automatic door opening and closing device 1, the first door panel 311 and the second door panel 321 perform a closing action.

It should be further explained that in the implementation states shown in Figures 9 to 12 above, the poultry house robot 8 can move in two directions (the frame 2 has two side frames 21 arranged parallel to each other front and rear, and the side frames 21 are respectively provided with opening and closing gate structures 3), that is, the poultry house robot 8 can move across from one area to another, or vice versa, from another area to this area.

As described above, the structural design of the automatic opening and closing gate device 1 for the poultry house fence allows the poultry house robot 8 to move smoothly across zones, and when the poultry house robot 8 moves across zones, the chickens 91 can be prevented from following the poultry house robot 8. That is, the poultry house robot 8 can be easily managed for cross-zone movement, thereby improving the convenience of poultry house management.

In addition, through actual experiments, it takes about 8 seconds for the first door panel 311 and the second door panel 321 to open or close. If the overall process is calculated, that is, the first door panel 311 and the second door panel 321 open, the poultry house robot 8 passes through the poultry house fence automatic gate opening and closing device 1, and the first door panel 311 and the second door panel 321 close, the time required is about 21 seconds to 23 seconds. In other words, in practical operation, the above-mentioned poultry house fence automatic gate opening and closing device 1 can fully meet the actual use requirements.

In actual manufacturing, the frame 2, the opening and closing gate structure 3, the first driving structure 41 and the second driving structure 42 can be manufactured in a modular manner to facilitate transportation and assembly. For example, the entire poultry fence automatic opening and closing gate device 1 can be manufactured in a modular manner with two halves, that is, the frame 2 is divided into left and right halves, one half of which is equipped with the first double-piece outward folding gate 31 and the first driving structure 41 and other structures, and the other half is equipped with the second double-piece outward folding gate 32 and the second driving structure 42 and other structures. As for the left and right halves, they can be connected to each other by means of snap-fitting, screwing, welding, etc.

The above description is only a preferred specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
