Description

Technical Field

[0001] This utility model relates to the field of pet feeder technology, specifically to a feeder that reduces the pressure of food on the food dispensing system. Background Technology

[0002] Pets provide companionship and emotional comfort to their owners. Currently, with the increasingly fast pace of life and rising living standards, more and more families are keeping pets. Because owners often need to go out or work, they cannot feed their pets promptly. Therefore, automatic pet feeders have emerged on the market. For example, Chinese utility model patent CN221104433U provides a pet feeder that stores pet food in a food storage bin and has a food dispensing channel on its casing. The dispensing mechanism opens or closes the connection between the dispensing channel and the food storage bin, thus dispensing food to the pet.

[0003] However, in this technical solution, the grain is stored inside the grain storage tank and flows into the grain dispensing mechanism in large quantities, burying the dispensing mechanism inside the grain. At this time, the dispensing mechanism is subjected to a large amount of gravity from the grain. When the dispensing mechanism is activated, it is resisted by the grain, resulting in a large load on the dispensing mechanism during startup. This may cause the starting current or load of the starting motor to exceed the rated current or rated load, reducing the life of the motor or causing damage to the motor due to excessive load. At the same time, because the gravity of the grain acts on the dispensing mechanism, the resistance during the operation of the dispensing mechanism is large during the grain conveying process, which can easily cause damage to the rotating shaft, impeller, and grain stirring rod.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a feeder that reduces the pressure of grain on the grain dispensing system, thereby solving at least one of the above-mentioned technical problems. The utility model adopts the following technical solution: A feeder for reducing the pressure of grain on a grain dispensing system includes a grain storage device for holding grain, the grain storage device having a grain outlet for grain to flow out, a grain dispensing system disposed inside the grain storage device for intermittently introducing grain into the grain outlet, a grain retainer being disposed inside the grain storage device, the grain retainer covering the grain dispensing system, and the orthographic projection of the grain retainer toward the grain dispensing system covering the grain dispensing system, and at least one grain leakage port being disposed on the grain retainer for grain to leak toward the grain dispensing system.

[0006] Furthermore, the grain storage device includes a base and a grain hopper mounted on the base. A grain outlet channel is provided on the base to connect the grain hopper with the grain outlet. The grain outlet system is located on the base to intermittently introduce grain into the grain outlet channel. The grain blocking cover is fixedly installed at the position where the base and the grain hopper are connected to each other to block the top of the grain outlet system.

[0007] Furthermore, a grain discharge funnel corresponding to the grain hopper is formed on the base. The bottom of the grain discharge funnel is connected to the grain discharge channel. The grain discharge system is set at the bottom of the grain discharge funnel. The grain retainer is fixed on the inner wall of the grain discharge funnel, and a grain passage gap is defined between the circumference of the grain retainer and the inner wall of the grain discharge funnel for grain to pass through.

[0008] Furthermore, the grain-blocking cover has a cover body and a plurality of legs disposed on the cover body, and all the legs are spaced apart from each other at equal angles, and the legs are detachably connected to the inner wall of the grain discharge funnel.

[0009] Furthermore, the cover has an arched structure and is equipped with an outwardly convex arc-shaped outer surface.

[0010] Furthermore, the grain discharging system includes a rotating shaft rotatably connected to the base and an impeller fixedly mounted on the rotating shaft. The impeller rotates to push the grain toward the grain discharging channel. The grain blocking cover is located on the upper side of the rotating shaft and covers the rotating shaft from above.

[0011] Furthermore, the center of the arc-shaped outer surface of the cover is located on the extension line of the axis of rotation.

[0012] Furthermore, all the grain leakage ports are arranged around the center of the arc surface of the cover, and the distance between the inner edge of the grain leakage port and the center of the arc surface of the cover is greater than the radius of the rotating shaft.

[0013] The beneficial effects of this utility model are as follows: This technical solution provides a feeder that reduces the pressure of grain on the grain discharge system. When grain flows into the bottom of the grain bin, it is blocked by a grain retainer. After being blocked, the grain falls through the discharge port to the lower side of the retainer. At this point, the pressure on the grain discharge system is only generated by the portion of grain located below the retainer, thus reducing the overall pressure on the system. It is worth noting that the grain discharge system mainly experiences the vertical force of the grain. Additionally, the lateral force from the grain filling the system is also reduced. After being blocked by the retainer, the weight of the grain inside the bin acts directly on the retainer, significantly reducing the vertical force exerted on the system. This reduces the starting current and load on the motor during startup and operation, ensuring reduced resistance and extending the system's lifespan. Attached Figure Description

Detailed Implementation

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0021] This technical solution provides a feeder that can reduce the pressure of grain on the grain dispensing system 200. When grain is stored in the grain bin, the grain blocking cover 300 can block the grain, preventing all the grain from flowing into the bottom of the grain bin and avoiding the grain from pressing against the grain dispensing system 200. This reduces the weight of the grain in the grain bin from directly acting on the grain dispensing system 200. At this time, when the grain system is started, the resistance of the grain in the grain bin to the grain dispensing system 200 can be reduced, which can effectively protect the normal operation of the grain dispensing system 200 and improve the service life of the grain dispensing system 200.

[0022] In this embodiment, as Figure 1-5 As shown, this technical solution provides a feeder that reduces the pressure of grain on the grain dispensing system 200. It includes a grain storage device 100 for holding grain, a grain outlet 101 for grain to flow out, and a grain dispensing system 200 disposed inside the grain storage device 100 to intermittently guide grain into the grain outlet 101. A grain retainer 300 is also disposed inside the grain storage device 100. The grain retainer 300 covers the grain dispensing system 200, and the orthographic projection of the grain retainer 300 toward the grain dispensing system 200 covers the grain dispensing system 200. At least one grain leakage port 301 is provided on the grain retainer 300 for grain to leak out toward the grain dispensing system 200.

[0023] During operation, after the grain flows into the bottom of the grain silo, such as... Figure 3 At this point, the grain will be blocked by the grain retainer 300. After being blocked by the grain retainer 300, the grain will fall into the lower side of the grain retainer 300 through the grain outlet 301. At this time, the pressure received by the grain discharge system 200 is only generated by the portion of grain located below the grain retainer 300, thereby reducing the overall pressure received by the grain discharge system 200. It is worth noting that, as Figure 5 As shown, the grain discharging system 200 mainly receives the vertical gravity of the grain. Additionally, due to the lateral force received by the grain discharging system 200 after it has been buried by the grain, the gravity of the grain inside the grain bin acts directly on the grain bin 300 after being blocked and limited by the grain retaining cover 300. This significantly reduces the vertical gravity exerted on the grain discharging system 200 by the grain inside the grain bin. Consequently, during the start-up and operation of the grain discharging system 200, the starting current and load of the motor are reduced, ensuring the resistance of the grain discharging system 200 during start-up and operation, and extending the service life of the grain discharging system 200.

[0024] In this embodiment, as Figure 1-4As shown, the grain storage device 100 includes a base 110 and a grain hopper 120 mounted on the base 110. A grain discharge channel 111 is provided on the base 110 to connect the grain hopper 120 with the grain outlet 101. A grain discharge system 200 is mounted on the base 110 to intermittently introduce grain into the grain discharge channel 111. A grain retainer 300 is fixedly mounted at the connection between the base 110 and the grain hopper 120, blocking the top of the grain discharge system 200. More specifically, a grain discharge funnel 112 corresponding to the grain hopper 120 is formed on the base 110. The bottom of the grain discharge funnel 112 is connected to the grain discharge channel 111. The grain discharge system 200 is located at the bottom of the grain discharge funnel 112. The grain retainer 300 is fixed to the inner wall of the grain discharge funnel 112, and a grain passage gap 113 is defined between the circumference of the grain retainer 300 and the inner wall of the grain discharge funnel 112 for grain to pass through.

[0025] The grain discharge funnel 112 allows the grain to flow more quickly toward the grain discharge channel 111. The grain retainer 300, positioned above the grain discharge funnel 112, creates a grain passage gap 113 between the circumference of the retainer 300 and the inner wall of the grain discharge funnel 112. This allows grain to pass through the gap and fall into the space below the retainer 300. Because the grain can fall into the space below the retainer 300 along the circumferential gap, it generates a force that propels the grain discharge system 200 toward the grain discharge system. A downward-sloping lateral force is applied to the system simultaneously along the circumference. Therefore, the lateral force on the grain dispensing system 200 is canceled out, leaving only vertical pressure. Since the grain is blocked and divided into two parts by the grain retainer 300, most of the grain's weight is blocked, significantly reducing the weight of the grain on the grain dispensing system 200 covered by the grain retainer 300. This reduces the load on the grain dispensing system 200 during startup and operation, and improves its service life.

[0026] In this embodiment, as Figure 4 As shown, the grain retainer 300 has a cover body 310 and several legs 320 disposed on the cover body 310. All legs 320 are spaced apart from each other at equal angles, and the legs 320 are detachably connected to the inner wall of the grain discharge hopper 112. By fixing the grain retainer 300 to the inner wall of the grain discharge hopper 112 through the legs 320, a grain discharge gap can be formed between the edge of the grain retainer 300 and the inner wall of the grain discharge hopper 112. Furthermore, the size of the grain discharge gap can be adjusted by setting the length of the legs 320.

[0027] In this embodiment, the cover 310 has an arched structure and is equipped with an outwardly convex arcuate outer surface. By setting the outer surface of the cover 310 as an outwardly convex arcuate surface, it can withstand the downward gravity of the grain, such as... Figure 5 As shown, the cover 310 can apply a reaction force to the grain in an upward direction, thereby counteracting gravity. Furthermore, the arc-shaped outer surface guides the grain as it falls downwards, causing it to move towards the grain outlet gap, thus improving the grain's fluidity.

[0028] In this embodiment, the grain discharging system 200 includes a rotating shaft 210 rotatably connected to the base 110 and an impeller 220 fixedly mounted on the rotating shaft 210. The impeller 220 rotates to push the grain toward the grain discharging channel 111. A grain blocking cover 300 is disposed above the rotating shaft 210, covering it from above. When grain discharging is required, a motor is connected to the rotating shaft 210 to drive it to rotate. At this time, the impeller 220 rotates with the rotating shaft 210, intermittently pushing the grain located below the grain blocking cover 300 into the grain discharging channel 111, allowing the grain to flow out along the grain discharging channel 111. During the start-up and operation of the grain discharging system 200, after the grain inside the grain bin is blocked and isolated by the grain blocking cover 300, a small portion of the grain can flow along the grain leakage port 301 and the grain passage gap 1. 13 grains fall below the grain retaining cover 300. At this time, since the grain retaining cover 300 divides the grain discharge funnel 112 into two parts, the grain discharge system 200 is mainly subjected to the pressure of the grain located below the grain retaining cover 300. This greatly reduces the impact of the grain's gravity on the grain discharge system 200. During startup, it significantly reduces the startup current and load. At the same time, it also reduces the resistance of the rotating shaft 210 and impeller 220, thereby avoiding damage to the rotating shaft 210 and impeller 220, and thus greatly improving the lifespan of the grain discharge system 200. Furthermore, in this embodiment, to improve the flowability of the grain during discharge, a grain stirring rod 230 is fixedly installed on the rotating shaft 210. The stirring of the grain stirring rod 230 loosens the grain located below the grain retaining cover 300, making it easier for the impeller 220 to move and discharge the grain.

[0029] When the grain flows along the grain passage gap 113 to the space under the cover 310, the grain flowing into the space can be evenly distributed around the rotating shaft 210, thereby canceling the lateral force on the rotating shaft 210. The center of the arc outer surface of the cover 310 is set on the extension line of the axis of the rotating shaft 210.

[0030] In this embodiment, when grain falls into the space under the cover 310 through the grain leakage openings, all grain leakage openings are arranged around the center of the arc surface of the cover 310, and the distance between the inner edge of the grain leakage opening and the center of the arc surface of the cover 310 is greater than the radius of the rotating shaft 210. In this embodiment, eight grain leakage openings are arranged at equal angles and surround the center of the cover 310, so that the grain falling along the grain leakage openings will not fall directly onto the rotating shaft 210. At the same time, it will be evenly distributed around the rotating shaft 210, and the rotating shaft 210 is blocked by the center of the cover 310, which can prevent the grain from directly pressing the rotating shaft 210, thereby reducing the pressure on the rotating shaft 210 and improving the service life of the grain dispensing system 200.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
