Description

Technical Field

[0001] This utility model relates to the field of feeders, specifically to a rodent-proof automatic feeder. Background Technology

[0002] For entertainment or production purposes, humans often keep pets, livestock, or other economic animals. Feeding them regularly and in measured amounts is currently considered a more scientific method of animal feeding. Overfeeding can overburden an animal's digestive system, prolong digestion time, and lead to obesity and impaired mobility. If a mixed feed is used, animals may only eat their preferred foods, resulting in nutritional imbalances. Insufficient feeding can also negatively impact an animal's health and development. Furthermore, feeding is typically done 2-3 times a day, sometimes before dawn, and sometimes during the caretaker's working hours. Manually feeding each time is extremely inconvenient.

[0003] The patent with publication number CN203912893U discloses an automatic timed feeder in which food automatically flows onto a tray and then the food on the tray is swept to the bottom of the tray at regular intervals.

[0004] However, in existing technology, feeding troughs are usually placed in the animal's activity area, with a feeder installed at the bottom. The feeder dispenses food at regular intervals and in measured quantities to achieve the effect of feeding at set times and in measured quantities. Since the animal activity area is usually a semi-open area, and rats are common animals in cities with a very high reproductive rate, the aroma of the food will attract rats to sneak in and steal it. Rats may also directly attack smaller animals, and some animals are quite valuable, such as racing pigeons, which are usually priced from several thousand to tens of thousands of yuan. If a racing pigeon wins a race, it can also receive more prize money. Therefore, if a racing pigeon is attacked and injured by a rat, it will cause huge losses to its owner.

[0005] Currently, there are two main solutions to prevent rats from stealing food:

[0006] I. Killing rats is an option, but existing methods are often unsatisfactory: rat poison can easily lead to animals accidentally ingesting it, and rat traps can easily injure people and animals. Once a rat trap is triggered, rats will urinate under the influence of the irritant, and other rats will realize the danger by smelling the urine and stay away, making it difficult to reuse the rat trap.

[0007] Second, given the limitations of current methods for catching rats, directly protecting the feeding container is the only way to fundamentally solve the problem of rats stealing food. Once rats realize they cannot obtain food no matter what, they will naturally stay away from animal activity areas and will no longer attack animals. However, because rats have a powerful bite, increasing the hardness of the feeding container's outer shell would require using more expensive materials, significantly increasing costs.

[0008] Therefore, there is a need for an automatic feeding device that can feed animals on a regular schedule, protect the feeder from rat attacks, and is also economical and practical. Utility Model Content

[0009] The present invention aims to provide a rodent-proof automatic feeder that can feed animals on a regular schedule, protect the feeder from rodent attacks, and is also economical and practical.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: a rodent-proof automatic feeder, comprising a feeding cylinder, a feeding outlet at the bottom of the feeding cylinder, and a feeding device at the bottom of the feeding outlet. The feeding device is normally in a closed state and is used to block the feeding outlet and open at a set time. When the feeding device opens, it releases the blockage of the feeding outlet, and the food at the bottom of the feeding cylinder passes through the feeding outlet and the feeding device in sequence for the animal to eat.

[0011] The feeding tube is equipped with a support and protection structure at the bottom, which includes a protective part. The protective part is used to isolate the feeder from the outside rats. Rats cannot pass through the support and protection structure. The bottom of the protective part is equipped with a food dispensing channel. When the feeder is opened, the food passes through the feed opening, the feeder and the food dispensing channel in sequence.

[0012] The beneficial effects of this plan are:

[0013] 1. Rats are rodents, extremely destructive, and have a strong jumping ability. As long as the feeding trough is not placed in an enclosed area, rats are likely to find the feeding trough and determine the location of the feeding opening.

[0014] Research has revealed that, for economic and practical reasons, most commercially available feeding containers are made of stainless steel, while the feed dispenser is made of plastic. The feed dispenser contains components such as a motor, making it difficult to make at home; therefore, purchasing a ready-made product is more economical. Consequently, the plastic feed dispenser becomes the weakest point in the entire feeding system, making it more susceptible to being chewed by rats.

[0015] Typically, mice can jump between 30 and 70 cm high. Even if the feeding opening is more than 30 cm off the ground, the mouse can still jump and enter the feeding device, damaging its structure to obtain food.

[0016] Therefore, this solution includes a specially designed support and protective structure to isolate and protect the feeder, preventing rats from jumping up and biting it, causing damage. Regardless of how the support and protective structure is damaged or deformed, as long as rats cannot pass through it, it will not affect the feeding of the feeder, nor will it easily cause deformation of the feeding tube and its lower feeder, leading to uncontrolled food leakage from the outlet. This prevents rats from being attracted to continue bumping into it. Consequently, rats cannot bite the feeder, nor can they bite the support and protective structure, and it is impossible to stimulate them to urinate or use scent for marking.

[0017] Furthermore, there's no need to replace high-strength materials; common metal protective structures are sufficient, making them easy to manufacture. This achieves the dual benefits of allowing for regular animal feeding while protecting the feeding dishes from rodent attacks, making it both economical and practical.

[0018] 2. This design includes a food outlet at the bottom of the protective section, ensuring that food can fall smoothly to a position where the animals can eat during feeding time.

[0019] 3. Research has shown that the maximum height a mouse can reach while standing is no more than 15cm. Therefore, the bottom of the protective part is usually set to be more than 15cm off the ground (20cm in this design), so that the mouse can only jump to attack the protective part. The mouse cannot use its momentum in the air, thus reducing the damage to the protective part caused by the mouse.

[0020] 4. The inventor designed the feeder based on the pigeon feeder and extended its applicability to all animals fed by humans (such as chickens, ducks, geese, pigs, dogs, cats, etc.) with the main purpose of rodent control and to improve the automation of the feeding process.

[0021] 5. For feeding wires that are easily accessible to mice, you can apply butter to the wires. The butter will corrode the mice's intestines and stomach, thus causing the mice to stay away from the wires on their own.

[0022] Furthermore, the protective section is a cylindrical tube with its opening facing upwards, and a support tube is provided at the bottom of the feeding tube with its opening facing downwards. The support tube is housed within the protective section. This design provides double protection for the feeder, preventing it from being attacked by rats.

[0023] Furthermore, the protective section includes a cylindrical frame, with protective netting on the sides and bottom of the cylindrical frame, and the grain outlet channel is the mesh of the protective netting at the bottom of the protective section.

[0024] Furthermore, the support and protective structure includes a support part, which includes several legs arranged circumferentially on the lower side of the protective part. A diffuser is provided at the center below the protective part. The diffuser includes a conical part and an impact part at the upper end of the conical part. The slope of the side of the impact part is greater than the slope of the side of the conical part. The area between the diffuser and the legs is the feeding area for the animal.

[0025] Furthermore, the gaps between the legs are designed to allow the animal's head to pass through while feeding, and these gaps are smaller than the width of the animal's body. This design prevents the animal from entering the feeding area and soiling the food, ensuring the food remains clean and hygienic.

[0026] Furthermore, protective nets are provided on the sides and bottom of the protective section, and the grain outlet channel is the mesh of the protective net at the bottom of the protective section.

[0027] Furthermore, the protective section is a rectangular frame, and the supporting protective structure also includes a support section. The support section includes legs respectively located at the four corners of the bottom of the rectangular frame, and a tray is provided between the four legs. The width of the tray is smaller than the distance between adjacent legs. This arrangement facilitates the removal of the tray for cleaning.

[0028] Furthermore, the feeder and feeding container are designed separately, with the feeder connected to the supporting and protective structure. This design makes it easy to remove the feeding container separately for cleaning.

[0029] Furthermore, it also includes a height-increasing tube, the lower end of which is detachably connected to the upper end of the feeding tube. The height-increasing tube increases the capacity of the feeding tube, and the top of the height-increasing tube is detachably connected to the bottom of another height-increasing tube. This design facilitates extending the feeding cycle, ensuring that the food in the tube can meet the needs for a longer period when the keeper is away for extended periods.

[0030] Furthermore, the feeder includes a housing, on which a feed motor, a feed shaft, and a timer are provided. The output shaft of the feed motor is horizontally positioned and connected to the feed shaft. A feed switch is provided on the feed shaft. The feed switch causes the feed at the bottom of the feeding tube to fall out by rotating.

[0031] The timer is connected to the feeding motor, and the timer is used to control the start time and running time of the feeding motor.

[0032] Furthermore, the feeding switch includes an impeller, the impeller includes a disc, the disc has several moving blades arranged circumferentially, and side baffle structures are provided on the front and rear sides of the disc respectively;

[0033] The side baffle structure, wheel, and two moving blades are used to seal the feeding port;

[0034] When the feeder is opened, the food leaves the feed outlet as the moving blades rotate.

[0035] Furthermore, the casing is equipped with a feed-blocking brush, which blocks the feed. That is, during non-feeding periods, it prevents the feed from falling directly down from the gap between the impeller and the feed outlet. During feeding periods, the impeller rotates, causing the feed to break through the obstruction of the feed-blocking brush, thus completing the feeding process. In addition, the feed-blocking brush can generate an upward reaction force on large particles of feed, preventing large particles of feed from getting stuck between the moving blades, thereby avoiding food entrapment.

[0036] Furthermore, the feeding switch includes a blocking part. When the blocking part rotates above the feeding shaft, it blocks the feeding port. When the blocking part moves away from above the feeding shaft, the opening of the feeding port expands, and the amount of food flowing out of the feeding port gradually increases.

[0037] Furthermore, the feeding switch also includes a stirring part, which partially invades the feeding port when the stirring part rotates above the feeding shaft.

[0038] Furthermore, the support and protection structure includes an upward-facing protective part and a downward-facing support barrel. The food dispenser is fixed inside the support barrel, which is housed within the protective part. The protective part is equipped with support legs.

[0039] Furthermore, the sealing part is a shell with a fan-shaped cross-section, and the straight side of the fan-shaped cross-section is provided with a transfer opening, through which food enters and exits the interior of the sealing part.

[0040] This solution also has the following effects:

[0041] 1. The feed dispensing motor has an adjustable feed dispensing rate, which is adjusted by the running time. The feed dispensing motor rotates at a constant speed, and the running time is controlled by a timer. The timer is usually accurate to the second, thus ensuring that the feeding time is strictly controlled by the breeder.

[0042] 2. The bottom of the feeding container is designed in an inverted cone shape to prevent food from piling up at the bottom and to ensure that the food eventually falls into the outlet, rather than accumulating in the bottom corner of the feeding container to rot and spoil.

[0043] 3. Place the tray between the legs rather than directly under the legs for easy access and cleaning; similarly, the feeding tube and dispenser are designed separately for easy removal and cleaning of the feeding tube.

[0044] 4. To reduce the amount of food adhering to the sealing or agitating parts, this solution uses a food-retaining brush to brush off the adhering food. After brushing the adhering food together, the food enters the groove formed between the moving blades along the inclined direction of the food-retaining brush. After the groove passes the position of the food-retaining brush, the groove rotates so that the opening faces downward, and the food in the groove falls below the supporting protective structure.

[0045] 5. The feeder in this design uses a horizontally positioned feeding shaft. One half of the feeding shaft is a semi-circular section with a blocking part, and the other half is several plate-shaped stirring parts. During the rotation of the feeding shaft, some of the blocking part and stirring parts will pass through the feeding port and enter the feeding tube, thereby stirring the food in the feeding tube and preventing food from getting stuck.

[0046] 6. After the food falls, it collides with the impact part of the disperser and scatters. The more food in the feeding hopper, the faster the food at the bottom falls, the greater the impact force, and the farther the food falls from the impact part. When the food falls close to the impact part, it means that the food in the feeding hopper should be replenished.

[0047] 7. To further enhance effect 3 and make the food drop location more obvious, in this solution, the sealing part is designed as a hollow shell. When the sealing part rotates to below the food outlet shaft, most of the food enters the interior of the sealing part through the transfer opening. When the transfer opening faces downward, the food in the sealing part pours down.

[0048] This setup reduces the rotation speed of the feeding shaft, ensuring that as much food as possible enters the sealing section. Then, it allows as much food as possible to impact the disperser's impact section at once. This reduces the resistance of friction on the food, minimizing food residue on the disperser. As a result, the food falls into the animal's feeding area as much as possible, reducing the chance of food falling on the disperser and not being eaten by the animal, which could attract rats instead.

[0049] When the food in the feeding hopper decreases, the amount of food passing through the sealing part will also decrease significantly after the feeding shaft completes one revolution, and more food will remain on the disperser, thus reminding the owner to replenish the food in the feeding hopper.

[0050] 8. To reduce food waste, the disperser can be removed and the feeding area expanded so that animals can directly enter the area under the supporting protective structure to feed. Attached Figure Description

[0058] The following detailed description illustrates the specific implementation method:

[0059] The reference numerals in the accompanying drawings include: feeding tube 1, feeding outlet 11, supporting and protective structure 2, cage 21, support leg 22, protective part 23, tray 3, shell 41, feeding motor 42, feeding shaft 43, extension section 44, food blocking brush 45, impeller 51, wheel 52, moving blade 53, sealing part 54, transfer opening 55, stirring plate 56, perforation 57, support barrel 6, ventilation hole 61, disperser 7, conical part 71, impact part 72.

[0060] Example 1

[0061] Example 1 is basically as follows Figures 1-3 As shown: A rodent-proof automatic feeder, comprising, from top to bottom, a feeding tube, a supporting and protective structure, and a tray.

[0062] The feeding tube is made of aluminum and has a conical lid. The lid is counterweighted to increase the stability of the feeding tube and prevent it from being knocked over by mice when there is little food inside. The feeding tube is used to hold the animal's food. The inner side of the bottom surface of the feeding tube is inverted conical, and there is a feeding outlet at the center of the bottom surface of the feeding tube, that is, the feeding outlet is located at the lowest position of the feeding tube. The feeding outlet can be a circular hole, but in this embodiment, the feeding outlet is a rectangular hole.

[0063] The supporting and protective structure includes a protective section and a support section. The protective section can be a rectangular mesh cage. The protective section is welded to the bottom of the feeding tube. The height of the protective section is 20cm. The protective section is equipped with a feeding device. The protective section has corresponding notches at the feeding opening and feeding device positions. The support section is located on the lower side of the protective section. The support section includes four legs. The four legs are welded to the four corners of the bottom of the protective section. The height of each leg is 20cm. The tray is square and placed between the four legs.

[0064] The feeder is used to seal the feed outlet and open it at fixed intervals. When the feeder opens, the seal on the feed outlet is released, and the feeder slides across the food at the bottom of the feeding container. The food passes sequentially through the feed outlet, the feeder, and the supporting protective structure, finally falling below the supporting protective structure for the animal to eat. Specifically, the feeder includes a shell, which is welded to the bottom of the feeding container. Openings are located at the center of both the upper and lower sides of the shell to allow food to pass through. Figure 3 As shown, a feeding motor is bolted to the housing. The feeding motor can be controlled by a controller to rotate a certain number of revolutions at a fixed time or a fixed time interval. This is existing technology and will not be described in detail. The output shaft of the feeding motor is set horizontally and is keyed to one end of the feeding shaft. The other end of the feeding shaft is inserted from the inside of the housing and rotatably connected to the housing.

[0065] The feeding shaft is divided into a basic section and an extension section along its length. The length of the basic section is adapted to the width of the feeding opening. Figure 2The horizontal direction of the feeding inlet is the length direction, and the direction perpendicular to the paper is the width direction. The basic section is equipped with a feeding switch, which is used to block and open the feeding inlet. The feeding switch includes an impeller, and the impeller includes a wheel disk. The basic section passes through the wheel disk and is welded to the wheel disk. The wheel disk is integrally formed with several moving blades in the circumferential direction. Side baffle structures are provided on the front and rear sides of the wheel disk respectively. In this embodiment, a part of the shell is used as a side baffle structure on the side of the wheel disk closer to the feeding motor, while the diameter of the extended section of the feeding shaft is larger than that of the wheel disk. The extended section serves as a support structure on the side of the wheel disk away from the feeding motor. The top of the extended section can abut against the lower surface of the feeding tube. Since the extended section has a circular cross-section, there will inevitably be some gaps between the extended section and the feeding tube. These gaps should be minimized as much as possible, or the food in the feeding tube should be prevented from passing through these gaps.

[0066] When the feeding motor stops working, the housing, impeller, extension section, and two moving blades enclose the feeding opening to seal it; as... Figure 2 As shown, the moving blades used for sealing are not necessarily adjacent; the distance between two moving blades and the length of the feeding inlet is determined to achieve the sealing effect. When the feeder opens, the food leaves the feeding inlet as the moving blades rotate. When the moving blades rotate to below the feeding shaft, all the food between the moving blades has fallen down.

[0067] If the feed outlet is blocked and the space between the driving wheels is full of feed, the feed will be squeezed from the basic section into the extension section when the feed shaft rotates, thus reducing the amount of feed between the driving wheels and ensuring smooth rotation of the feed shaft; considering the above, if Figure 2 As shown, this solution has a grain-blocking brush inside the housing. The brush handle of the grain-blocking brush is bolted to the inner side of the housing. The grain-blocking brush prevents the food from falling directly down and prevents the food from getting stuck. The length of the grain-blocking brush is greater than the length of the basic section of the feeding shaft. In this embodiment, the length of the grain-blocking brush is equal to the sum of the lengths of the basic section and the extended section of the feeding shaft.

[0068] In addition, it includes at least one heightening tube, which is used to increase the capacity of the feeding tube. The lower end of the heightening tube is used to be threaded to the feeding tube, and the top of the heightening tube is used to be threaded to the bottom of another heightening tube.

[0069] Example 2

[0070] The difference between Example 2 and Example 1 is that the protective part is a rectangular frame, and protective netting is welded to the sides and bottom of the rectangular frame. The grain outlet channel is the mesh of the protective netting at the bottom of the protective part. Two long strip support plates are welded to the upper sides of the rectangular frame, and the support cylinder is a rectangular cylinder, with the bottom of the support cylinder supported on the support plates.

[0071] Example 3

[0072] The difference between Example 3 and Example 1 is as follows: Figure 4 , Figure 5As shown, it also includes a support bucket with the opening facing downwards. The support and protective structure includes a protective part of a cage structure with the opening facing upwards. The support bucket is housed inside the protective part. The feeder is fixed inside the support bucket. The shell of the feeder is welded to the support bucket. Several ventilation holes are opened on the side wall of the support bucket. In this embodiment, the ventilation holes are arch-shaped. The side wall of the protective part is composed of several vertically equidistant uprights. The bottom of the protective part is composed of several equidistant horizontal bars. Several vertical support legs are welded circumferentially to the lower edge of the protective part. The gap between the support legs is used for the animal's head to pass through for feeding. The gap between the support legs is smaller than the width of the animal's body.

[0073] The tray is round, with legs supporting it. A disperser is welded to the center of the tray. The disperser includes a conical part, and the upper part of the conical part has a bullet-shaped impact part integrally formed. The side of the impact part is perpendicular to the ground. The area between the disperser and the legs is the animal's feeding area.

[0074] Example 4

[0075] The difference between Example 4 and Example 5 is that: Figure 6 , Figure 7 As shown, the feeding switch includes a blocking part and a stirring part. The blocking part is a semi-cylindrical shell welded to the feeding shaft 43 and coaxial with it. The semi-circular straight side of the blocking part has a transfer opening. The stirring part consists of three stirring plates. One side of each of the three stirring plates is welded to the feeding shaft. The included angle between the three stirring plates is 45°. Each stirring plate has a rectangular perforation to ensure that the food between the stirring plates can enter the blocking part through the perforation.

[0076] When the blocking part rotates above the feeding shaft, it blocks the feeding opening; when the blocking part moves away from above the feeding shaft, the opening of the feeding opening widens, and the amount of food flowing out of the feeding opening gradually increases; when the stirring part rotates above the feeding shaft, it partially invades the feeding opening.
