Description

A food supply device Technical Field

[0001] The present invention relates to the technical field of animal breeding, and more particularly to a food supply device. Background Art

[0002] At present, feeders on the market are widely used as products for automatic feeding of grains. There are three main types:

[0003] The first category: bucket-type feeder. The main technology of the feeder is to place the food to be fed in a bucket. There is a rotating impeller at the bottom of the bucket. The motor is controlled by the control panel to rotate. The motor drives the impeller to rotate to move the food at the bottom of the bucket to fall out of the discharge channel or outlet at the bottom, thereby achieving the function of timely and quantitative food supply.

[0004] The main disadvantages of this bucket feeder are as follows:

[0005] 1. There are strict requirements on the size range of food, which is limited by the impeller spacing and is generally only suitable for certain sizes, such as food with a diameter of less than 12MM.

[0006] 2. The impeller's rotation direction is perpendicular to the falling direction of the food. Under the combined effects of gravity, the impeller's centrifugal force, and the shear force, the rotating food will generate frictional resistance with the bottom, side walls, and impeller, blocking the impeller's rotation. Forcing the food to rotate can easily produce fragments and cause the food to be stuck between the rotating impeller and the barrel outlet, preventing the food from being discharged and causing the pet to starve.

[0007] 3. The bottom of the storage barrel narrows to the impeller, and the food is tightly squeezed together and stuck, resulting in uneven and inaccurate discharge of food, with more, less, or no food being discharged.

[0008] 4. The impeller blades have a complex structure and are difficult to clean.

[0009] 5. The squeezed impeller and food can easily scrape off the plastic, metal, and soft rubber particles on the impeller and side walls, causing food contamination.

[0010] 6. The center of gravity is high and pets may be easily knocked over.

[0011] The second type: a turntable feeder, which uses a motor to drive a horizontal turntable with multiple food grids. The turntable is covered with a lid with an opening. When the lid is turned to the opening position, the food in the grid is exposed for the animals to eat.

[0012] This turntable feeder has the following disadvantages:

[0013] 1. The food in the turntable or the lid is easily stuck, or the food overflows and gets stuck when the pet moves the bowl.

[0014] 2. Due to the size limitation of the structure, there are only a few compartments for separating meals, which is limited to a few meals and the quantity is small, which cannot meet the needs of providing food when the owner is away for many days.

[0015] 3. The lid needs to be rotated, and there is a gap between the grid turntable and the lid, which is not sealed. Food is easy to spoil and become unfresh, and insects can crawl in.

[0016] 4. Regardless of whether the pet eats or not, there is always a grid of food exposed to the air, the food will quickly deteriorate or be eaten by cockroaches, which is unhygienic.

[0017] The third type: self-falling feeder, which uses a container with food in it, turned upside down, with a small opening on the lower side. The food rolls down to the food bowl below under the action of gravity for the pet to eat. When the pet eats part of the food in the bowl, the food falls out under the action of gravity to replenish it.

[0018] This self-falling feeder has the following disadvantages:

[0019] 1. It is impossible to manually control the amount and frequency of food distribution, and it is impossible to control the animal's food intake and frequency, which can easily make the pet fat and unhealthy.

[0020] 2. It is not sealed, so it is easy to absorb water, deteriorate and allow cockroaches to crawl in, causing food contamination, which can make pets sick if eaten.

[0021] 3. The center of gravity is high and pets may be easily knocked over.

[0022] In summary, the above feeders may cause food to get stuck easily, or the fan-shaped food bowls are inconvenient to feed, or the sealing is poor, or the impeller structure is complex and difficult to clean. When the owner is away, they cannot provide food in a quality, clean, and smooth manner, causing the animals to starve, become sick, or even die. Summary of the Invention

[0152] The other end of the first material preparation barrel 202 is connected to one end of the second material preparation barrel 203, and the radius of one end of the second material preparation barrel 203 is greater than the radius of the other end of the second material preparation barrel 203;

[0153] The other end of the second material preparation barrel 203 is a blind hole;

[0154] The other end of the second preparation cylinder 203 is connected to one end of the discharge cylinder 205; the other end of the discharge cylinder 205 serves as the discharge port 4;

[0155] The side walls of the second material preparation cylinder 203 and the material discharging cylinder 205 are both provided with through holes;

[0156] The transfer bin 204 is connected to the through hole of the second material preparation cylinder 203 and the through hole of the material discharge cylinder 205;

[0157] A transmission wheel 6 is provided on the outer wall of the discharge cylinder 205 , and the transmission wheel 6 surrounds the outer wall of the discharge cylinder 205 .

[0158] In this embodiment, a transmission wheel 6 may also be provided on the outer wall of the main barrel 201 , and the transmission wheel 6 surrounds the outer wall of the main barrel 201 .

[0159] The driving end of the driving motor 13 is engaged with the transmission wheel 6, and the main control board 16 controls the driving end of the driving motor 13 to rotate, thereby driving the transmission wheel 6 to rotate, thereby rotating the main silo 2;

[0160] Since the main material bin 2 is tilted, under the action of gravity, as it rotates, the food stored in the main material barrel 201 passes through the first preparation barrel 202, the second preparation barrel 203, the transfer bin 204, and the discharge barrel 205 in sequence, and finally the food is discharged from the discharge port 4 of the discharge barrel 205.

[0161] The radius of one end of the first material preparation barrel 202 is smaller than the radius of the other end of the first material preparation barrel 202 , and the radius gradually increases from one end of the first material preparation barrel 202 to the other end of the first material preparation barrel 202 , forming a horn structure.

[0162] The radius of one end of the first preparation barrel 202 is equal to the radius of the main barrel 201. The radius of the other end of the first preparation barrel 202 is equal to the radius of one end of the second preparation barrel 203;

[0163] The radius of the second material preparation barrel 203 gradually decreases from one end to the other end thereof. Preferably, the radius of the other end of the second material preparation barrel 203 is smaller than the radius of the main material barrel 201 .

[0164] The radius of the first preparation barrel 202 increases from small to large, so that when food enters the first preparation barrel 202 from the main material bin 2, the sliding slope is larger and steeper than that of the main material bin 2. Under the action of gravity, the food will slide to 202 at a faster speed. The preparation area formed by the radius of the first preparation barrel 202 increasing from small to large and the radius of the second preparation barrel 203 decreasing from large to small can allow more food to gather at the through hole and discharge port of the second preparation barrel 203 at a steeper slope, allowing the food to enter the transfer bin 204 in the shortest time.

[0165] One side of the transfer bin 204 is in contact with the outer wall of the second material preparation barrel 203 ; the other adjacent side of the transfer bin 204 is in contact with the outer wall of the material discharge barrel 205 .

[0166] When the transfer bin 204 is at the lowest position, under the action of gravity, the food stored in the main barrel 201 enters the transfer bin 204 through the through holes of the first preparation barrel 202 and the second preparation barrel 203 in sequence.

[0167] When the transfer bin 204 is at the highest position, the food in the transfer bin 204 enters the discharge barrel 205 through the through hole of the discharge barrel 205 and is discharged from the discharge port 4 of the discharge barrel 205 to achieve food delivery.

[0168] In this embodiment, an outlet cover 22 for sealing the outlet of the transfer bin 204 is provided in the discharge barrel 205; the shape of the outlet cover is arc-shaped, and its curvature is the same as the curvature of the circular arc of the discharge barrel 205; one end of the outlet cover is rotatably connected to one side of the feed port of the discharge barrel 205.

[0169] In this embodiment, an outlet cover 22 is provided in the through hole connecting the transfer bin 204 and the discharge barrel 205 (i.e., the feed port of the discharge barrel 205), which can cover the feed port of the discharge barrel 205. When the main silo 2 rotates around the central axis of the main silo 2, the outlet cover 22 will flip around the axis and leave the surface when it approaches the highest position, and the outlet cover 23 will automatically open under the action of gravity. At this time, the material in the main silo 2 is entering the discharge barrel 205 from the transfer bin 204 and the feed port of the discharge barrel 205 under the action of gravity, and finally discharged from the feed port of the discharge barrel 205. When the main silo 2 continues to rotate around the central axis, the outlet cover 22 slowly closes around the axis until the transfer bin 204 approaches the lowest point, preventing the ingress of moisture, insects, cockroaches, etc., and ensuring that the food is isolated from the outside world. The outlet cover 22 is provided with a locking mechanism to lock the outlet cover 22. Alternatively, the outlet cover 22 may be designed with a magnetic end at one end thereof. By designing the channel of the discharge barrel 205 to be magnetic, the main control panel can be used to change the direction of the magnet to control the flipping or tightening of the outlet cover 22. Under normal conditions, the transfer bin 204 is also controlled to be at the lowest point to prevent the ingress of moisture, insects, cockroaches, etc., ensuring that the food is isolated from the outside world, thereby ensuring the dryness and freshness of the food.

[0170] In this embodiment, the structure of the outlet cover is shown in Figures 5 and 6. The outlet cover 22 includes a cover body 25, a rotating shaft seat 26, a rotating shaft, and a locking part 27. The rotating shaft is rotatably arranged on the rotating shaft seat. The rotating shaft seat is used to be fixed to the inner wall of the discharge barrel and is located at the edge of the inlet of the discharge barrel. One end of the cover body is connected to the rotating shaft. The cover body rotates around the rotating shaft with the rotating shaft as the center. One end of the rotating shaft of the locking part is rotatably connected; the rotating surface of the locking part is perpendicular to the rotating surface of the cover body. When the locking part rotates and merges with the cover body, both the cover body 25 and the locking part can rotate. When the locking part rotates and separates from the cover body and is on the opposite side, the locking part and the cover body 25 are connected to the same rotating shaft. At this time, the cover body 25 is in a locked state and cannot rotate.

[0171] In this embodiment, as shown in Figures 7 and 8, a transfer bin 204 is located between the second preparation barrel 203 and the discharge barrel 205. The size of the transfer bin 204 determines the amount of material discharged each time. Different sizes and capacities can be designed to facilitate replacement as needed. With each rotation, the transfer bin 204 moves from its lowest position to its highest position and then from its highest position to its lowest position, clearing and refilling the food within it. Controlling the rotation angle controls the feeding and discharging of food. Food enters the transfer bin 204 and the main barrel 201 at intervals, ensuring a sealed seal during these intervals. The transfer bin 204 is a container with two openings: an inlet 208 for food entering the transfer bin 204 from the main barrel 201 and the first preparation barrel 202; and an outlet 209 for food exiting the transfer bin 204 and entering the discharge port 4, located on the outer periphery of the sidewall of the discharge barrel 205. The outlet 209 is located on the side of the inlet 208 away from the main barrel 201. Preferably, the outlet 209 is larger than the inlet 208 to ensure that large food is not blocked by the outlet 209. The transfer bin 204 has a large capacity and a small opening. When the main barrel 201 rotates, the transfer bin 204 also rotates along with the axis of the main barrel 201, from the highest position to the lowest position. At this time, the outlet 209 is at the highest position of the transfer bin 204, and the inlet 208 is approximately halfway between the outlet 209 and the lowest position, and is above the lowest position of the transfer bin 204. At this time, the food falls from the inlet 208 into the lower position of the transfer bin 204 under the action of gravity. Since the outlet 209 is located above the inlet 208, the food will not fall out of the outlet 209 under the action of gravity. At the same time, since the outlet cover 22 is in the covered state under the action of gravity at this time, possible material jumping out is also prevented; when rotating from 0° to 180°, when the transfer bin 204 rotates to the highest position, the outlet 209 changes from the highest position in the transfer bin 204 to the lowest position, and the inlet 208 is above the outlet 209. Food falls from the outlet 209 to the inlet and outlet 4 under the action of gravity. At this time, the outlet cover 22 is in the open state under the action of gravity. At this time, the preparation feeding area formed by the first preparation barrel 202 and the second preparation barrel 203 connected to the transfer bin 204 is higher than the adjacent main barrel 201, and at this time the inlet 208 is tilted downward, and the material in the main barrel 201 cannot enter the preparation feeding area space here. Only the food in the transfer bin 204 falls into the outlet 4. When rotating the main silo 2, ensure that the rotation trajectory lines of the inlet 208 and the outlet 209 do not intersect, and when the inlet 208 is at the lowest point, the outlet 209 is at the highest position, and when the inlet 208 is at the highest point of the transfer bin 204, the outlet 209 is at the lowest position of the transfer bin 204, ensuring feeding and discharging.Preferably, the entrance 208 is generally set near the middle distance position line between the transfer bin 204 and the rotation axis in the main silo 2. In this way, when rotating, the food at the bottom of the transfer bin 204 will not fall back into the main silo 2 from the entrance 208, or as little as possible. The exit 209 is set at the minimum rotation trajectory point of the transfer bin 204 to ensure that all the food in the transfer bin 204 is discharged.

[0172] Furthermore, as shown in FIG9 , the support base 3 includes a base 301 , a front support leg 302 of the base, and a rear support leg 303 of the base;

[0173] The front support legs 302 and the rear support legs 303 are respectively arranged at both ends of the base 301; and the height of the front support legs 302 is lower than the height of the rear support legs 303;

[0174] The two ends of the main silo 2 are rotatably arranged on the front support legs 302 and the rear support legs 303 of the base;

[0175] The drive motor 13 is arranged in the front support leg 302 of the base, or in the rear support leg 303 of the base, and the driving end of the drive motor 13 is meshed and connected with the transmission wheel 6;

[0176] In this embodiment, the driving motor 13 is disposed in the front supporting leg 302 of the base, and the driving end of the driving motor 13 is meshedly connected to the transmission wheel 6 on the outer wall of the discharge barrel 201 .

[0177] Or the driving motor 13 is arranged in the rear supporting foot 303 of the base, and a transmission wheel 6 is provided on the outer wall of the end of the main barrel 201. The transmission wheel 6 surrounds the outer wall of the main barrel 201, and the driving end of the driving motor 13 is engaged with the transmission wheel 6 on the outer wall of the main barrel 201.

[0178] The front and rear support legs 302 and 303 of the base are adjustable to adjust the elevation angle of the main hopper 2. For viscous materials, a larger elevation angle is required to accelerate the descent. A weighing sensor is installed at the bottom to measure the weight of each discharge and calculate the amount of remaining food.

[0179] In a specific embodiment, as shown in FIG2 , the food supply device is further provided with a light sensor 15 for sensing whether there is food in the transfer bin and a position sensor for sensing the position of the transfer bin; the transfer bin 204 is provided with a light-transmitting area 24 for allowing light to penetrate the transfer bin; a light emitter is provided at a position opposite to the light sensor 15 for directly irradiating the light sensor 15 through the light-transmitting area 24;

[0180] The light sensor 15 and the position sensor are electrically connected to the main control board 16;

[0181] The light emitter 23, the transfer chamber 204 and the light sensor 15 are on the same straight line;

[0182] When it is detected that the transfer bin 204 has rotated to the lowest position, the light emitting device is controlled to emit light directly to the photosensitive sensor 15, or the light emitting device is set to light up when it is detected that the transfer bin 204 has rotated to different positions; if the photosensitive sensor 15 detects light, it is determined that there is no remaining food in the transfer bin 204; if the photosensitive sensor 15 does not detect light, it is determined that there is remaining food in the transfer bin 204.

[0183] In another specific embodiment, as shown in FIG1 , if the transfer bin 204 is disposed on the outer wall of the main barrel and the discharge barrel and is connected to the main barrel and the discharge barrel, a light sensor 15 for sensing whether there is food in the transfer bin and a position sensor for sensing the position of the transfer bin can be provided on the rear support leg 303 of the base, and a corresponding light emitter can be provided on the front support leg 302 of the base. In this case, the side walls of the transfer bin opposite the rear support leg 303 and the front support leg 302 of the base are both configured as light-transmitting areas, that is, they can be made of transparent materials. Of course, the light emitter can also be provided on the rear support leg 303 of the base, and the corresponding light sensor 15 can be provided on the front support leg 302 of the base.

[0184] In another specific embodiment, as shown in FIG2 , the outer wall of the transfer bin is at the same horizontal plane as the outer wall of the main barrel; the light emitter can be set on the sealing cover of the main barrel 201, and the light sensor 15 can be set on the front support foot 302 of the base.

[0185] Light passes through the light emitter on the main barrel 201, such as a linear laser emitted by a laser diode, and is directly emitted from the main barrel 201 into the transfer bin. If there is material in the transfer bin, it will roll into the transfer bin 204 under the action of gravity. If the light passes through the bottom of the transfer bin 204, the presence of food will block the light, and the light sensor installed on the front bracket 302 of the base cannot receive the light, thereby detecting whether the bin is out of material. Or when it is detected that the transfer bin is out of material, but the gravity sensor measures the weight of material, it can notify the main barrel through the network and sound that there is clumping food, blocking the discharge port 208. If you are not on site, the main control panel can remotely control the motor to rotate back and forth to shake out the clumping food, or set it to automatic, thereby determining whether there is food in the transfer bin 204 or the main bin based on whether the light sensor detects light.

[0186] In this embodiment, a power supply circuit may be independently provided on the sealing cover 206 to control the light emitting device to emit light, and a power supply for supplying the light emitting device to operate may be provided on the sealing cover accordingly; the light emitting device may also be controlled by the main control board.

[0187] There is no requirement for the appearance shape of the transfer bin 204, and it can be set to be cylindrical, spherical, olive-shaped, conical, fan-shaped, ring-shaped, etc.

[0188] In this embodiment, the transfer bin 204 is cylindrical, and the side of the transfer bin 204 connected to the outer wall of the second material preparation barrel 203 is set as an inclined surface, and the inclined surface is provided with an inlet 208 connected to the through hole of the second material preparation barrel 203; the inclination of the inclined surface is the same as the inclination formed by the outer wall of the second material preparation barrel 203.

[0189] The transfer bin 204 is provided with an outlet 209 on the side connected to the outer wall of the discharge barrel 205, which is connected to the through hole of the discharge barrel 205. The transfer bin 204 is also provided with a fixing structure 210. Correspondingly, a fixing groove is provided on the outer wall of the discharge barrel 205, which cooperates with the fixing structure 210, or the transfer bins 204 and 205 are directly integrally formed. The fixing structure 210 and the fixing groove cooperate to connect the transfer bin 204 to the discharge barrel 205, allowing the transfer bin 204 to be connected to the discharge barrel 205 or to replace the transfer bin with a different capacity.

[0190] In another specific embodiment, as shown in FIG8 , the main silo 2 further includes a material preparation barrel outer cover 7 ;

[0191] The material preparation barrel outer cover 7 is sleeved on the main material bin 2, and one end of the material preparation barrel outer cover 7 is rotatably connected to the outer wall of the main material barrel 201;

[0192] One end of the material preparation barrel outer cover 7 is rotatably connected to the outer wall of the discharge barrel 205 and is located between the transmission wheel 6 and the second material preparation barrel 203 .

[0193] The outer cover 7 of the material preparation barrel has a cylindrical appearance. In this embodiment, the outer cover 7 is provided to cover the first material preparation barrel 202, the second material preparation barrel 203 and the transfer bin 204 for aesthetic reasons. It is also convenient to set the positioning point 8 on the outer cover 7 later.

[0194] In another specific embodiment, the outer wall of the discharge barrel 205 is provided with a positioning plate; the positioning plate is provided with a plurality of positioning points 8 arranged around the discharge barrel 205;

[0195] The support base 3 is provided with a sensor for sensing the positioning point 8, thereby determining the rotation angle of the main silo 2 and the position of the transfer silo; the sensor is provided with at least one;

[0196] The sensor is electrically connected to the main control board 16 .

[0197] The sensor is arranged on the front supporting foot (302) of the base.

[0198] Or a code disk is provided on the outside of the main barrel 2, and a photoelectric detection device is provided at a position corresponding to the protective shell or the base support foot to sense the different positions and speed information of the code disk rotation; the photoelectric detection device is electrically connected to the main control board 16.

[0199] In this embodiment, the code disk is a digital encoder that measures angular displacement. It offers advantages such as high resolution, high measurement accuracy, and reliable operation, making it the most commonly used displacement sensor for measuring shaft angular position. Code disks come in two types: absolute and incremental. The former directly generates a digital code corresponding to the angular position; the latter uses a computing system to add or subtract the incremental pulses generated by the rotating code disk relative to a reference number.

[0200] This embodiment consists of a photoelectric encoder consisting of a code disk and a photoelectric detection device. The code disk is a circular plate with a certain diameter and a number of rectangular holes opened at equal intervals. Since the photoelectric code disk is coaxial with the motor, when the motor rotates, the code disk rotates at the same speed as the motor. The detection device composed of electronic components such as light-emitting diodes detects and outputs a number of pulse signals. By counting the number of pulses output by the photoelectric encoder per second, the current motor speed can be reflected.

[0201] In another embodiment, different black and white stripes are printed on the outside of the main barrel. The direction of the stripes is the same as the radial direction of the main barrel. The stripes rotate with the motor drive, and the output pulse signal is detected by the reflective photoelectric sensor detection device. By calculating the photoelectric code, the specific position and angle can also be known.

[0202] In this embodiment, positioning points 8 are set at equal intervals on the discharge barrel 205. These positioning points 8 are sensed by sensors to determine the rotation angle of the main material bin 2, which is beneficial to control the rotation angle and specific position of the main material bin 2 and realize smooth discharge of food.

[0203] The positioning point 8 has one or more properties including position, light, and magnetism. When the positioning point 8 rotates to the sensor position, the sensor sends a signal to the control system to locate the specific position of the rotating main silo 2, thereby controlling the rotation angle range for discharging and opening the outlet lid 22, the rotation angle range for closing the outlet lid 22 when discharging is not completed, and the number of times the material is discharged.

[0204] In this embodiment, if a drive wheel 6 is provided on the outer wall of the rear end of the main barrel, a corresponding drive motor is provided at the corresponding position of the base rear support leg 303. Of course, whether the drive motor is provided at the corresponding position of the base rear support leg 303 or the base front support leg 302, only one end is driven. Alternatively, drive motors can be provided at both the base front support leg 302 and the base rear support leg 303 to simultaneously drive the main barrel rotation.

[0205] The four corners of the bottom of the base 301 are provided with anti-tilting support foot suction cups 304, which can firmly suck the bottom to the ground to prevent movement or tipping when the pet is using it.

[0206] The support foot suction cup 304 at the bottom of the base 301 can be provided with a telescopic structure to achieve adjustable height of the end of the base 301. According to the actual needs of the user, the height of the end of the base 301 can be adjusted, thereby adjusting the tilting angle to make it easier for food in the main material bin to be discharged from the main material bin.

[0207] In a specific embodiment, as shown in Figures 10 and 11 , the food supply device includes a main silo protective shell 5;

[0208] The main silo protective shell 5 includes an upper protective shell 9 and a lower protective shell 10;

[0209] The cross-sections of the upper protective shell 9 and the lower protective shell 10 are preferably semicircular;

[0210] One side of the upper protective shell 9 is hinged to one side of the lower protective shell 10, and the other side of the upper protective shell 9 is detachably connected to the other side of the lower protective shell 10 by a buckle;

[0211] The two ends of the lower protective shell 10 are respectively arranged on the front supporting feet 302 and the rear supporting feet 303 of the base;

[0212] The main silo 2 is rotatably disposed in the main silo protective shell 5 .

[0213] The buckle comprises a male buckle component 12 and a female buckle component 19 that cooperates with the male buckle component 12;

[0214] If the male buckle component 12 is provided on the upper protective shell 9 , the corresponding female buckle component 19 is provided on the lower protective shell 10 ;

[0215] If the male buckle component 12 is provided on the lower protective shell 10 , the corresponding female buckle component 19 is provided on the upper protective shell 9 .

[0216] The main hopper protective shell 5 protects the main hopper 2 from being entangled in surrounding objects, including pets, during rotation. More importantly, some pets, especially cats, are timid and may startle or refuse to eat due to fear when the main hopper 2 rotates. The main hopper protective shell 5 prevents these issues and creates an aesthetically pleasing industrial appearance for the food supply device.

[0217] In this embodiment, the lower protective shell 10 may also be provided with a light sensor 15 for sensing the presence of food in the transfer bin and a position sensor for sensing the position of the transfer bin; the light sensor 15 and the position sensor are disposed on the lower protective shell 10 at the end away from the discharge port. A light emitter may also be disposed on the lower protective shell 10 at the discharge port end.

[0218] In a specific embodiment, the front and rear ends of the main silo protective shell 5 are provided with a plurality of rolling pairs 11, or bearings are provided on the outer wall of the main silo 2, so that the main silo 2 and the main silo protective shell 5 are rollingly connected.

[0219] This embodiment is advantageous in reducing friction by providing a rolling pair 11 or a bearing.

[0220] In a specific embodiment, the food supply device further includes at least one spare silo 21;

[0221] At least one spare material bin 21 is detachably connected end to end;

[0222] The main silo 2 is provided with a feed interface at one end of the feed inlet;

[0223] The discharge port of the standby silo 21 is detachably connected to the feed interface of the main silo 2;

[0224] The feed inlet of the standby silo 21 is provided with a detachable sealing cover 206 and a feed interface is reserved.

[0225] The lengths of the standby silo 21 and the main silo 2 can be set according to actual needs to store different quantities of food.

[0226] This embodiment meets the need for capacity expansion by connecting the spare silo 21 to the feed interface of the main silo 2. When the owner is out, the main silo 2 can be equipped with a spare silo connector at the rear end, allowing the capacity to be easily increased when needed and removed when not needed, thus reducing space occupation.

[0227] In a specific embodiment, it further includes a food tray 1 disposed directly below the discharge port 4 of the main silo 2;

[0228] The food tray 1 is provided with a first gravity sensor for sensing the weight of food, and the first gravity sensor is electrically connected to the main control board 16;

[0229] When the first gravity sensor detects that the weight of the food in the food tray 1 is less than the set first weight threshold, the main control board 16 controls the drive motor 13 to drive the main hopper 2 to rotate, thereby releasing the food;

[0230] When the first gravity sensor detects that the weight of the food in the food tray 1 is greater than the set second weight threshold, the main control board 16 controls the drive motor 13 to drive the main hopper 2 to stop rotating, thereby stopping the feeding of food;

[0231] And / or the eating speed and / or food amount of the pet can be calculated based on the weight difference of the food dish 1 detected at two different time points.

[0232] In this embodiment, the weight of the food in the food tray 1 is detected by the first gravity sensor to determine whether food needs to be added. In this embodiment, the calculated pet eating speed and / or food intake can be sent to a mobile terminal for the user to view or communicate with the remote background, and remote management and report output can be performed through the remote background. When the first gravity sensor detects that the weight of the food in the food tray 1 is less than the set first weight threshold, the main control board can also first send a message that there is no food in the food tray 1 to the mobile terminal or the remote background, allowing the user or the remote background to determine whether food needs to be added. The main control board 16 can also intelligently and automatically control the drive motor 13 to drive the main hopper 2 to rotate to achieve food addition.

[0233] According to the above-mentioned food supply device, the specific structure is shown in Figures 11, 12, 13 and 14.

[0234] In a specific embodiment, the food feeding device further includes a camera group, a lighting lamp, an infrared sensor or a dynamic sensor, a microphone, a speaker or a buzzer, and a light sensor arranged on the support base 3 or the main silo protective shell;

[0235] The camera group, lighting, infrared sensor or motion sensor, speaker or buzzer, and microphone are all electrically connected to the main control board 16;

[0236] The camera group includes at least one camera group, which is respectively arranged around the support base (301) and is used to sense the activities of the pet around the feeding device.

[0237] The camera group is used to sense whether the food is eaten each time and which pet eats it, whether the main feed bin 2 is discharged, whether the pet is eating, the number of times it eats, and recognize the barcode or QR code of the food, so as to determine the amount of food put in, the number of times it is put in, and the amount eaten by each pet for statistical control, and monitor the activities of the pets around the food supply device;

[0238] The light sensor is used to detect ambient light. When the ambient light brightness is detected to be less than a preset first brightness value, the main control board 16 controls the lighting to work; when the ambient light brightness is detected to be greater than a preset second brightness value, the main control board 16 controls the lighting to turn off.

[0239] The infrared sensor or the dynamic sensor is used to detect whether a pet is present or near the food supply device;

[0240] The pickup is used to detect sounds emitted on site; by detecting the pet's calls and determining whether the pet is near the food supply device, it can comprehensively determine whether the pet is hungry and then control whether to release food. The sounds emitted on site include pet sounds, human sounds, etc.

[0241] The camera group records, tracks, analyzes and provides feedback on the falling of materials, the number of times the pet comes and the consumption. Every time the pet leaves food, it automatically triggers the adjustment of the next feeding amount to reduce waste. It can also record the environment on-site video.

[0242] In this embodiment, the camera group, lighting, infrared sensor, and microphone are all arranged at the front end of the upper protective shell 9. A monitoring window 14 is provided at the front end of the upper protective shell 9, and the camera group, lighting, infrared sensor, and microphone are arranged in the monitoring window 14.

[0243] The speaker or buzzer is used to make a sound and call the pet to eat, or to drive away non-own pets from eating or intruders; it can also be designed to play the calls of the opposite sex to attract pets to eat or play corresponding sounds and sound waves to drive away non-own pets from eating or intruders.
