Description

Technical Field

[0001] This utility model belongs to the field of animal cage technology, specifically relating to a rapid feeding structure for IVC cages. Background Technology

[0002] Laboratory animal cages are crucial equipment used in life science research and drug development for the housing and management of laboratory animals. Their core function is to provide a standardized living environment for laboratory animals and ensure the standardization of experimental procedures and animal welfare.

[0003] Currently, feeding in these cages generally involves direct feeding. Specifically, the zookeeper needs to open the cage door and place the food dish directly into the cage or remove the empty food dish from the cage. This traditional method carries the risk of the laboratory animals escaping or scratching or biting the zookeeper's hands during the opening of the cage door and the removal of the food dish, posing a direct threat to personnel safety. Utility Model Content

[0004] This invention provides a rapid feeding structure for IVC cages, which solves the defects of existing technologies that require opening the cage door to feed the animals, which can lead to animals escaping or scratching the keepers' hands.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a rapid feeding structure for IVC cages, comprising a cage, which further includes: Feed hopper; A feeding channel that extends through the feeding hopper; A discharge bin, which is tilted and fixed between the feed bin and the cage; A discharge channel, which runs through the discharge hopper and is connected to the inlet channel; A feeding mechanism, wherein the feeding structure is disposed within the feed hopper, and is used to connect or block the feed channel and the discharge channel.

[0006] Ideally, the feeding mechanism includes a discharge plate rotatably mounted within the feed hopper.

[0007] Optimally, the feeding structure further includes limiting grooves formed on both sides of the feeding hopper, limiting posts fixed on both sides of the discharging plate and cooperating with the limiting grooves, and a support plate fixed inside the feeding hopper for supporting the discharging plate.

[0008] Optimally, the feeding mechanism further includes a rotating shaft rotatably mounted in the feed hopper, a rotating handle fixed to one end of the rotating shaft, and an anti-slip part surrounding the outer circumference of the rotating handle, and the feeding plate is fixed on the rotating shaft.

[0009] Ideally, it also includes a guide section that is tilted and fixed between the discharge bin and the feed bin.

[0010] Ideally, the angle between the material guide and the horizontal plane is greater than the angle between the discharge bin and the horizontal plane.

[0011] Ideally, it also includes a cover plate that is rotatably mounted on top of the feed hopper.

[0012] Ideally, it also includes a fixing plate fixed to the side of the discharge bin near the cage and a fixing hole penetrating the fixing plate.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model of IVC cage uses a rapid feeding structure by setting up an interconnected feed hopper and discharge hopper on one side of the cage. During feeding, food is put into the feed hopper from the outside. The feeding mechanism connects or blocks the feed hopper and discharge hopper, so that food can be put into the food bowl inside the cage from the outside without opening the cage door. This avoids the safety hazards of laboratory animals escaping or scratching the hands of the keepers. Attached Figure Description

[0015] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0016] like Figure 1 , 2 The diagram shows a quick-feeding structure for the IVC cage of this invention. This structure is fixed to one side of the cage, allowing food to be placed into the food bowl inside the cage without opening the cage box. An opening is provided on one side of the cage box, connecting the internal and external spaces. The food bowl is welded to the side of the cage box with the opening, and the upper surface of the food bowl is flush with the lower surface of the opening, facilitating food to fall into the bowl through the opening.

[0017] Feeding bin 1 is a hollow rectangular frame structure, welded together from four metal plates. The interior of feeding bin 1 forms a feeding channel 5, into which the feeder places solid granular food during feeding. Feeding bin 2 is fixed to the bottom of feeding bin 1 by welding (i.e., the inlet of feeding bin 2 is connected to the outlet of feeding bin 1, and food falls into feeding bin 2 through feeding bin 1).

[0018] The discharge bin 2 is constructed from four welded metal pieces. The interior of the discharge bin 2 forms a discharge channel 6 that connects to the feeding channel 5. The discharge bin 2 is tilted to allow food to fall easily into the cage box on one side under gravity. Figure 2 As shown, a guide section 11 is fixed between the feed hopper 1 and the discharge hopper 2 by welding, and the angle between the guide section 11 and the horizontal plane is greater than the angle between the discharge hopper 2 and the horizontal plane. When food falls from the feed channel 5, it first contacts the guide section 11 with a large angle, and the guide section 11 guides the food into the discharge hopper 2, facilitating the food's descent.

[0019] The fixing plate 3 is fixed to the side of the discharge bin 2 away from the feed bin 1 (i.e., the side of the discharge bin 2 closest to the cage opening) by welding, and the fixing hole 4 passes through the fixing plate 3. A through hole matching the fixing hole 4 is provided on the side of the cage with the opening. The fixing plate 3 is placed against the outside of the side of the cage with the opening, and the fastening bolts are passed through the fixing hole 4 and the through hole in sequence. The nut is then tightened on the other side, thereby fixing the discharge bin 2 to the side of the cage with the opening. The discharge channel 6 is connected to the opening of the cage. When food falls from the feed channel 5, it first contacts the steeply angled guide part 11. Under the action of the guide part 11, the food is guided into the discharge channel 6, and then falls into the feeding bowl inside the cage through the opening.

[0020] The rotating shaft 14 is mounted inside the feed hopper 1 via bearings (specifically, a bearing hole is provided on the side of the feed hopper 1 near the discharge hopper 2, and a bearing is installed in the bearing hole; the rotating shaft 14 is installed inside the bearing, and the normal rotation of the rotating shaft 14 is ensured by the action of the bearing). The discharge plate 12 is fixed to the rotating shaft 14 by welding, and the feeding channel 5 and the discharge channel 6 are connected or disconnected by rotating the discharge plate 12.

[0021] like Figure 3 As shown, the rotating handle 15 is fixed to one end of the rotating shaft 14. When the feeder rotates the rotating handle 15, it drives the rotating shaft 14 and the feed plate 12 to rotate synchronously, thereby opening the feed channel for food delivery or closing the feed channel. The anti-slip part 16 is arranged around the outer circumference of the rotating handle 15. When the feeder rotates the rotating handle 15, the anti-slip part 16 increases the friction of the hand and prevents slipping (the anti-slip part 16 is a protrusion arranged around the outer circumference of the rotating handle 15).

[0022] Limiting grooves 17 are provided on both sides of the feeding bin 1, and the limiting grooves 17 are arc-shaped. Limiting posts 18 are fixed to both sides of the feeding plate 12 by welding and cooperate with the limiting grooves 17. When the feeder turns the rotating handle 15 to feed, it will drive the feeding plate 12 to rotate synchronously. At this time, the limiting posts 18 on both sides of the feeding plate 12 move along the arc-shaped trajectory of the limiting groove 17 in the limiting groove 17, which improves the stability of the rotation of the feeding plate 12.

[0023] There are two support plates 13, which are fixed to the bottom of the feed hopper 1 by welding and are arranged opposite each other, as shown below. Figure 2 As shown, when the feeding plate 12 is in a horizontal state, the feeding plate 12 blocks the feeding channel 5 and the discharging channel 6. At this time, the feeding plate 12 abuts against the support plate 13, and the support plate 13 blocks the feeding plate 12.

[0024] The first boss 8 is fixed to the top of the feed hopper 1 by welding at intervals. The first boss 8 has a first shaft hole. The second boss 9 is fixed to one side of the cover plate 7 by welding. The second boss 9 has a second shaft hole. The first boss 8 and the second boss 9 are connected by a pivot. The pivot passes through the first shaft hole and the second shaft hole, so that the cover plate 7 can rotate relative to the feed hopper 1 about the axis of the pivot, thereby opening or closing the feed hopper 1.

[0025] The extension plate 10 is fixed to the side of the cover plate 7 away from the second protrusion 9 by welding. The design of the extension plate 10 makes it convenient for the breeder to open the cover plate 7.

[0026] First, the feeder opens the cover 7, puts food into the feeding bin 1, and then closes the cover 7. When feeding is needed, the feeder turns the rotating handle 15, causing the feed plate 12 in the feeding bin 1 to rotate counterclockwise, connecting the feeding channel 5 and the discharging channel 6. When the food falls from the feeding channel 5, it first contacts the steeply angled guide part 11, which guides the food to the discharging channel 6. Then, the food falls into the food bowl in the cage through the opening. The feeder can observe the amount of food in the food bowl in real time. Then, the feed plate 12 is turned in the opposite direction to close the feed plate 12, thus stopping the feeding.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
