Description

Technical Field

[0001] The invention relates to the technical field of animal breeding, and in particular to a self-cleaning breeding device and a self-cleaning breeding method. Background Art

[0002] Currently, when multiple small animals are kept in a single cage, the small animals may become dying or die during the breeding process due to internal or external factors (such as after the small animals undergo minimally invasive surgery or are injected with new drugs).

[0003] Because existing cages lack the function of automatically identifying and separating dying or dead individuals from healthy ones, if the experimenters fail to discover them in time (such as when the experimenters go out temporarily or when they get off work at night to rest) and clean them manually, the dying or dead animals may continue to spread pathogens and affect other healthy animals in the cage. What's worse, we have also found that some healthy animals (such as experimental mice) will eat the corpses of their own kind. Summary of the invention

DETAILED DESCRIPTION

[0018] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0019] See also Figure 1-3 The self-cleaning feeding device provided by the present invention comprises a feeding room 1, a movable door 4, a receiving room 2 and a disturbance roller 5. A conveyor belt 3 is provided at the bottom of the feeding room 1 for driving or transporting the feeding objects to change the resting position of the feeding objects. On the one hand, it is convenient to clean the excrement of the feeding objects, and on the other hand, it is convenient to transport the feeding individuals that are difficult to move or have died due to dying. The movable door 4 is arranged on the side wall of the feeding room 1 and is located above the conveying path of the conveyor belt 3. The movable door 4 is usually in a normally closed state. When the dying or dead feeding individuals need to be moved out of the feeding room 1, it is temporarily opened to connect the feeding room 1 with the receiving room 2 for a short time. The receiving room 2 is located at the end of the conveying direction of the conveyor belt 3 to receive the feeding individuals passing through the movable door 4 from the feeding room 1. The disturbance roller 5 is rotatably arranged in the feeding room 1 and close to the movable door 4, and a gap is left between the roller body and the upper conveying surface of the conveyor belt 3 to allow the lying feeding individuals to pass under, and a soft brush 51 (such as a brush) is arranged around the roller body to drive the feeding individuals close to the movable door 4. Generally, the disturbance roller 5 is connected to the conveyor roller of the conveyor belt 3 by transmission, so that the disturbance roller 5 and the conveyor belt 3 are started synchronously, and then the healthy or highly active breeding individuals are effectively driven away from the movable door 4 when the conveyor belt 3 is running, so as to prevent the healthy or highly active breeding individuals from flowing into the receiving room 2 when the movable door 4 is opened. Obviously, the disturbance roller 5 can also be provided with an independent driving mechanism.

[0020] Specifically, to determine the opening time of the movable door 4, we can monitor the life activity of the individuals in the breeding room 1 in real time based on existing non-contact vital signs monitoring technologies such as infrared thermal imaging technology, camera monitoring technology, etc., or we can use a contact monitoring solution to determine the life activity of the individuals. This application provides a passive contact determination solution, and the specific technical solution is as follows: Please refer to Figure 3 and 4The self-cleaning feeding device also includes a pressure sensor 44, which is arranged at the bottom of the movable door 4, and its detection end extends into the feeding room 1, so as to at least control the opening of the movable door 4 after continuously obtaining multiple pressure signals. Since the disturbance roller 5 and the conveyor belt 3 are started at the same time, the healthy or highly active breeding individuals will be driven away from the movable door 4, while the breeding individuals that have lost the ability to move will be transported by the conveyor belt 3 and pass under the disturbance roller 5 to abut against the bottom end of the movable door 4, and continue to press the movable door 4 as the conveyor belt 3 runs. At this time, the pressure sensor 44 on the door can obtain a continuous pressure signal, and then the controller of the device can determine based on the continuous pressure signal that there are dying or dead breeding individuals in the breeding room 1 and that they have been transported to the movable door 4, and then the controller controls the movable door 4 to open and close after a set delay, so that the conveyor belt 3 can transport the dying or dead breeding individuals in time and unload them into the receiving room 2 after the movable door 4, so as to complete the self-cleaning of the dying or dead breeding individuals in the breeding room 1, and effectively and timely separate the dying or dead breeding individuals from the healthy breeding individuals.

[0021] As a further improvement to the above scheme, please refer to Figure 3 , the movable door 4 includes a door body 41, a first electromagnetic suction block 42 and a second electromagnetic suction block 43. The two sides of the top of the door body 41 are rotatably connected to the inner wall of the breeding room 1; the first electromagnetic suction block 42 is arranged on the side of the top of the door body 41 away from the breeding room 1; the second electromagnetic suction block 43 is located outside the breeding room 1 and is arranged opposite to the first electromagnetic suction block 42, and the second electromagnetic suction block 43 can firmly adsorb the first electromagnetic suction block 42 after being energized, so that the door body 41 remains vertical to close the breeding room 1. When the second electromagnetic suction block 43 loses its magnetic attraction after being powered off, the bottom end of the door body 41 can swing after being pressed, specifically, the bottom end of the door body 41 rises toward the receiving room 2, and the top of the door body 41 and the first electromagnetic suction block 42 thereon are away from the second electromagnetic suction block 43, so that the breeding room 1 and the receiving room 2 are temporarily connected. Among them, the first electromagnetic suction block 42 is generally configured to attract a permanent magnet, and the second electromagnetic suction block 43 is configured to be a combination of a permanent magnet and an electromagnet.

[0022] As a further improvement to the above scheme, please refer to Figure 4-5 The receiving chamber 2 includes a rotating disk 6 and a receiving chamber 21. The rotating disk 6 is rotatably connected to the bottom of the receiving chamber 2, and its driving method can be as follows: Figure 4As shown, an outer gear ring is arranged on the outer periphery of the rotating disk 6, and the driving device drives the rotating disk 6 to rotate by meshing the gear with the outer gear ring. The receiving bin 21 is arranged on the top surface of the rotating disk 6 in a detachable manner (such as a drawer type) so that the experimenter can take out the receiving bin 21 separately to clean the breeding individuals in the bin, and there are multiple receiving bins 21 arranged around the rotation center of the rotating disk 6 to receive the breeding individuals that escape from the end of the conveying direction of the conveyor belt 3. Obviously, the top of the receiving bin 21 needs to be open. The specific method of using the receiving bin 21 is: the empty receiving bin 21 is pre-rotated to the lower part of the path where the reared individual falls off from the end of the conveyor belt 3 by the rotating disk 6, so as to receive the reared individual after the movable door 4 is opened. At the same time, the controller marks and numbers the receiving bin 21, and records the time when the movable door 4 is opened as the receiving time of the marked receiving bin 21, so that the experimenter can judge the dying or death time of the reared individual accommodated in the corresponding marked receiving bin 21 to promote the subsequent experiments; after the movable door 4 is closed and delayed for a set time, the rotating disk 6 rotates again to rotate the next empty receiving bin 21 to the lower part of the path where the reared individual falls off. Obviously, when the controller determines that the movable door 4 is open or identifies that there is a reared individual that is dying or dead in the rearing room 1 or records the receiving time, the corresponding information can also be prompted to the experimenter based on sound, light, image, remote alarm, etc.

[0023] As a further improvement to the above scheme, please refer to Figure 4-5, the receiving chamber 2 also includes a shielding plate 7, which is fixedly connected to the bottom plate or side wall of the receiving chamber 2 and is covered above the rotating disk 6 to close at least one receiving bin 21, and a notch is provided on its surface to allow at most one receiving bin 21 to be exposed. Preferably, the receiving chamber 2 also includes a slide 8 arranged obliquely, the high end of which is close to the end of the conveying direction of the conveyor belt 3, and the low end of which extends to the top of the notch, so as to receive the breeding individuals that escape from the end of the conveying direction of the conveyor belt 3 and slide the breeding individuals into the currently exposed receiving bin 21, and the falling path of the breeding individuals is adjusted by setting the slide 8. Obviously, the exposed receiving bin 21 is located below the falling path of the breeding individuals, and the closed receiving bin 21 includes an empty receiving bin and a used receiving bin. The closing of the remaining receiving bins 21 is to prevent the breeding individuals from spreading toxic gases or oxidizing and corrupting prematurely. Preferably, a flexible sealing layer is provided on the bottom surface of the shielding plate 7 to further seal the top opening of the storage bin 21 under the plate, further reducing the contact between the activated storage bin and the outside air. Since the rotating disk 6 rotates slowly, even if interference friction occurs between the top surface of the storage bin 21 and the flexible sealing layer, it does not affect the rotation. Furthermore, the storage chamber 2 also includes a ventilation duct (not shown in the figure), one end of which is connected to the external ventilation system, and the other end is inserted on the shielding plate 7 and connected to at least one storage chamber 2 under the shielding plate 7, so as to at least be used to pump out the air in the corresponding storage chamber 2 with the help of the external ventilation system. On the one hand, by pumping out the oxygen in the bin, oxidation corruption is further slowed down. On the other hand, if harmful gases have been generated in the bin, the ventilation duct can be pumped out together to achieve self-cleaning of the air in the storage bin 21. In particular, if there is a need to rescue dying farmed individuals or prevent healthy individuals from suffocating to death due to mistakenly entering the storage bin, vital signs monitoring equipment (such as infrared thermal imaging, camera monitoring equipment, etc., and the corresponding equipment can be set above the gap in the baffle plate 7) can also be set in the storage room 2 to further verify the life activity of the farmed individuals cleaned into the current marked storage bin. If the verification result is that the life activity is active, after the marked storage bin is rotated to be closed by the baffle plate 7, air with suitable temperature and humidity (such as directly extracted from the breeding room 1) can be transported to the marked storage bin through the ventilation duct to avoid its suffocation and death, and the corresponding information can be prompted to the experimenter based on sound, light, image, remote alarm, etc., so that the experimenter can know in time and come to rescue or save the farmed individual.

[0024] As a further improvement to the above scheme, please refer to Figure 5The self-cleaning feeding device also includes a cleaning tray 9, which is sandwiched between the upper conveying surface and the lower conveying surface of the conveyor belt 3, and the upper conveying surface and the lower conveying surface are both hollowed out, so that the excrement of the feeder falls into the cleaning tray 9 below through the hollowed-out conveying surface, thereby realizing the self-cleaning of the excrement in the feeding room 1. In order to further enhance the self-cleaning effect of the excrement, a scraper or a brush can be provided at the bottom of the movable door 4 to scrape off the dirt on the surface of the conveyor belt 3 during the operation of the conveyor belt 3, and the scraped dirt also falls into the cleaning tray 9 through the hollowed-out part. Obviously, the cleaning tray 9 can be further processed, that is: the self-cleaning feeding device also includes a cleaning module and a storage box 91; the cleaning module is provided on one side of the cleaning tray 9 for flushing the cleaning tray 9; the storage box 91 is located below the cleaning tray 9 on the side opposite to the cleaning module, for receiving the cleaning objects.

[0025] Based on all the above embodiments, it can be known that the self-cleaning breeding device claimed in the present application has at least three self-cleaning functions: first, automatically cleaning the dying or dead breeding individuals in the breeding room, realizing the automatic separation of the dying or dead breeding individuals and the healthy breeding individuals in the breeding room; second, automatically cleaning the excrement in the breeding room; third, automatically cleaning the air in the containment room contaminated by the dying or dead breeding individuals.

[0026] Based on the above self-cleaning feeding device, the present invention also provides a self-cleaning feeding method, comprising the following steps: S1, placing the feed in the feeding room 1, and adding at least an appropriate amount of food and water; in addition, the temperature, humidity, light, ventilation, oxygen concentration and other environmental conditions required by the feed can also be provided, so that the above-mentioned self-cleaning feeding device can also be equipped with one or more of a temperature and humidity detection unit, a humidification unit, a temperature adjustment unit, a disinfection unit, a ventilation unit and a lighting unit; S2. Simultaneously starting the conveyor belt 3 and the disturbance roller 5 based on a preset time interval to drive or move the feed to change the resting position of the feed; by starting the conveyor belt 3 at a fixed time, it is convenient to clean the excrement of the feed, and it is also convenient for the monitoring equipment to better judge the activity of the feed individuals (for example, when the feed is sleeping, the camera monitoring technology may be difficult to identify the survival status); S3, monitoring the life activities of the breeding individuals in the breeding room 1. If the life activity of at least one breeding individual is reduced to a set standard, the conveyor belt 3 and the disturbance roller 5 are kept in operation, and the movable door 4 is controlled to open and close with a delayed time, so that the conveyor belt 3 can transport and unload the dying or dead breeding individuals into the receiving room 2 in time, so as to complete the self-cleaning of the dying or dead breeding individuals in the breeding room 1.

[0027] Among them, regarding monitoring the vital activity of the breeding individuals in the breeding room 1, the present application also provides a passive contact judgment scheme: monitoring the pressure sensor 44 located at the bottom of the movable door 4 facing the side of the breeding room 1, and after continuously obtaining multiple pressure signals, it is determined that there are dying or dead breeding individuals in the breeding room 1 (that is, it is determined that the vital activity of at least one breeding individual is reduced to the set standard) and has been moved to the front of the movable door 4.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
